Japanese Patent Laid-Open No. 9-262600 (2nd page, FIG. 1)
[0004]
[Problems to be solved by the invention]
However, when removing odors with a deodorizing tower as in the past, it is necessary to construct a deodorizing tower by securing a space for installing the deodorizing tower around the processing tank. There was a problem that piping work for the duct pipe to be sent and wiring work for supplying power to the motor of the exhaust fan of the deodorizing tower were also required.
[0005]
In addition, when the activity of activated carbon etc. filled in the deodorizing tower decreases, the activated carbon is taken out from the deodorizing tower, activated and returned to the deodorizing tower again, or exchanged with new activated carbon, etc. for good deodorizing action. It is necessary to perform maintenance so that it can be maintained, but this maintenance work is troublesome.
[0006]
The present invention has been made to cope with the above problems, and an object of the present invention is to provide a deodorizing cover that allows the cover itself to have a deodorizing function, eliminates the need for a deodorizing tower, and allows easy maintenance. There is.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a deodorizing cover according to the present invention is formed by forming a suction part and an exhaust part in a cover having a hollow interior, and housing a tube filled with a deodorizing agent in the hollow interior. The exhaust part is communicated and an exhaust fan is attached to the exhaust part. Here, the tube is a concept including a unit in which a plurality of cartridges filled with a deodorizer are detachably connected.
[0008]
When this deodorizing cover is attached to the opening of the treatment tank and the exhaust fan is turned, the odor generated in the treatment tank is sucked from the intake part and moves in the tube toward the exhaust part. Deodorized in contact with the deodorizer and released from the exhaust section to the atmosphere by an exhaust fan. In this way, the cover itself exerts a deodorizing function, so as in the past, the installation space for the deodorization tower was secured around the treatment tank to construct the deodorization tower, and the duct pipe was installed from the treatment tank to the deodorization tower. Is completely unnecessary.
[0009]
In the deodorizing cover of the present invention, it is desirable that a solar cell module is installed on the upper surface of the cover and the motor of the exhaust fan is driven using the electric power generated by the solar cell module.
[0010]
With such a configuration, wiring for supplying power to the motor of the exhaust fan from the outside becomes unnecessary, so that there is no inconvenience that the wiring becomes an obstacle when the cover is opened and closed. In particular, the solar cell module is effective as a motor power source for the exhaust fan of the deodorizing cover because the power generation amount increases on a sunny day with high temperature and high odor generation.
[0011]
Further, in the deodorizing cover of the present invention, an inspection port is formed on the upper surface of the cover, and the cover is detachably covered with the inspection port, and the end of the tube is detachably connected to the intake and exhaust portions. Is desirable.
[0012]
With this configuration, when the activity of the deodorizer filled in the tube decreases, open the lid, put your hand through the inspection port, disconnect the intake and exhaust sections from the tube, and take out the tube. The tube can be exchanged by simply inserting a tube filled with a new deodorizer into the hollow interior from the inspection port and connecting both ends of the tube to the intake and exhaust sections, making maintenance easy . In that case, if a tube is used in which a plurality of the cartridges described above are detachably connected to form a unit, the replacement work when the activity of the deodorant is reduced can be performed more easily.
[0013]
Furthermore, in the deodorizing cover according to the present invention, it is desirable that the waterproof cover is floated and attached to the exhaust part.
[0014]
With such a configuration, the rain cover is prevented from entering the exhaust portion by the waterproof cover, so that there is no fear that the exhaust fan or the motor of the exhaust portion gets wet with rain water or the rain water enters the tube from the exhaust portion. In addition, since the waterproof cover is mounted so as to float from the exhaust section, there is no problem with exhaust.
[0015]

FIG. 1 is a perspective view showing a usage state of a deodorizing cover according to an embodiment of the present invention, FIG. 2 is a plan view of the deodorizing cover, and FIG. 3 is a longitudinal sectional view of the deodorizing cover in use.
[0017]
The deodorizing cover 1 is made of FRP or synthetic resin, and includes a curved top plate 2, front and rear side plates 3, and a bottom plate 4 curved with a curvature substantially equal to the top plate 2, as shown in FIG. The interior 5 is hollow. And the flange part 3a is formed in the lower end of the side plate 3 of front and rear, as shown in FIG. 2, FIG.
[0018]
A box-shaped intake portion 6 is formed on one end side (right end side in FIG. 3) of the hollow interior 5, and a suction port 6 a of the intake portion 6 is opened in the bottom plate 4. Further, a box-shaped exhaust part 7 is formed on the other end side (the left end side in FIG. 3) of the hollow interior 5, and a discharge cylinder 7 a of the exhaust part 7 is attached through the top plate 2. An exhaust fan 8 is attached inside the discharge cylinder 7a, and a waterproof cover 9 is attached above the discharge cylinder 7a. The waterproof cover 9 is attached so as to float so as not to close the upper end opening of the discharge cylinder 7a.
[0019]
As shown in FIGS. 2 and 3, two flexible tubes 10 filled with a deodorizing agent 10 a are accommodated in parallel in the hollow interior 5 of the cover 1. Both ends of each tube 10 are detachably connected to the intake section 6 and the exhaust section 7 by a one-touch detachable joint 10b, and the intake section 6 and the exhaust section 7 communicate with each other through the tube 10. As the deodorizing agent 10a, activated carbon which has a large adsorbing power and can be obtained at low cost is preferably used.
[0020]
The tube 10 may have a long length as shown in FIG. 3, but a tube cartridge having a length of about 1/2 to about 1/3 of the tube 10 is attached with a one-touch detachable joint. Of course, it is also possible to use a unit in which two to three are detachably connected.
[0021]
As shown in FIGS. 1, 2, and 3, a solar cell module 11 in which semiconductor elements that convert sunlight into electrical energy are arranged and packaged is installed at the center of the top plate 2. Wiring (not shown) is performed so that the motor 8a of the exhaust fan 8 can be driven using the electric power generated in step.
[0022]
In addition, two inspection ports 12 are formed on both sides of the solar cell module 11 of the top plate 2, and a lid 13 is placed on each inspection port 12 so as to be freely opened and closed.
[0023]
As shown in FIGS. 1 and 3, the deodorizing cover 1 having the above configuration is placed side by side on the opening of the processing tank 14, and the flange portions 3 a of the left and right side plates 3 are fixed to the processing tank 14 with anchor bolts and nuts.

It is fixed to the processing tank 14 with a nut. In addition, as shown in FIG. 1, it is not necessary to cover all the opening of the processing tank 14 with the deodorizing cover 1, and it covers the opening of the processing tank 14 by using the normal cover without the deodorizing function and the deodorizing cover 1 in combination. This is enough.
[0024]
When the deodorizing cover 1 is attached to the opening of the treatment tank 14 as described above, the motor 8a of the exhaust fan 8 is driven using the electric power generated by the solar cell module 11, and the exhaust fan 8 is turned. The odor generated in the above is sucked into the suction part 6 from the suction port 6a of the cover bottom plate 4 and moves in the tube 10 toward the exhaust part 7, and in the middle of the deodorizing agent 10a in the tube 10 is contacted and deodorized, The exhaust fan 8 releases the air from the discharge cylinder 7a of the exhaust unit 7 to the atmosphere. Therefore, it is not necessary to secure an installation space for the deodorization tower around the treatment tank 14 and construct the deodorization tower, and it is not necessary to connect a duct pipe from the treatment tank 14 to the deodorization tower.
[0025]
In addition, when the motor 8a of the exhaust fan 8 is driven using the power of the solar cell module 11 like the deodorizing cover 1, no wiring for supplying power to the motor 8a of the exhaust fan 8 from the outside is required. There is no inconvenience that wiring is obstructive when the cover 1 is opened and closed. In particular, the solar cell module 11 is extremely effective as a power source for the motor 8a of the exhaust fan 8 of the deodorizing cover 1 because the amount of power generation increases on the day when the generation amount of odor increases, that is, on the day when the temperature is high and clear. .
[0026]
Further, when the activity of the deodorant 10a filled in the tube 10 is lowered, both the lids 13 are opened and hands are inserted from the inspection ports 12, and the one-touch attachment / detachment joints 10b at both ends of the tube 10 are disconnected. The tube 10 can be easily replaced simply by removing the tube 10 and inserting a tube filled with a new deodorizer into the hollow interior 5 from the inspection port 12 and connecting the one-touch attachment / detachment joints at both ends of the tube to the intake portion 6 and the exhaust portion 7. It can be performed. Therefore, the deodorizing cover 1 is easy to maintain.
[0027]
Further, when the waterproof cover 9 is attached above the discharge cylinder 7a of the exhaust part 7 as in the deodorizing cover 1, the waterproof cover 9 prevents rainwater from entering the exhaust part 7, so that the exhaust fan 8 There is no need to worry that the motor 8a gets wet with rainwater or that rainwater enters the tube 10 from the exhaust part 7.
[0028]
【The invention's effect】
