A device for collecting combustion products in a tank flue is shown in figures 1-5. Comprising a transverse tube 1. One end of the transverse pipe 1 is communicated with the tank body air outlet pipe 4, and the other end is communicated with the heat exchanger air inlet 27; two iron ore powder adsorption mechanisms are arranged in the transverse tube 1 along the gas flow direction, each iron ore powder adsorption structure comprises an outer tube 2 which is vertically and fixedly arranged, an inner tube 3 which is adapted in the outer tube 2, and a magnetic attraction mechanism 7 which is arranged in the outer tube 2, wherein the outer tube 2 and the inner tube 3 are sealed, the upper end and the lower end of the outer tube 2 are attached to the inner wall of the transverse tube 1 and are fixedly connected, and accordingly the two ends of the outer tube 2 are closed. The two sides of the outer tube 2 are vertically provided with strip-shaped grooves 5 which are opposite to the air flow, wherein, as shown in figure 1, the left side strip-shaped groove 5 is used for air inlet, the right side strip-shaped groove 5 is used for air outlet, the lower end of the inner tube 3 penetrates out of the transverse tube 1 and is in threaded connection with a material receiving cap 6, and a magnet 26 is suspended in the outer tube 2; the magnetic attraction mechanism 7 comprises a vertical rod 71, an iron block fixedly connected to the top end of the vertical rod 71 and attracted to the magnet 26, and a strip electromagnet 73 fixedly arranged on the vertical rod 71, wherein the iron block and the magnet 26 are of an annular structure, an inserting rod 8 is fixedly arranged in the magnet 26, a slot 9 for inserting the inserting rod 8 is formed in the top surface of the vertical rod 71 downwards, the attraction force between the magnet 26 and the iron block is larger than the gravity of the magnetic attraction mechanism 7 and smaller than the gravity received when the magnetic attraction mechanism 7 is attracted by iron ore powder, a supporting rod 12 for supporting the vertical rod 71 is fixedly arranged in the inner tube 3, a sensor 13 is arranged at the lower part of the inner wall of the inner tube 3, the sensor 13 can be a signal transmitting unit and a signal receiving unit which are arranged on two sides of the inner wall of the inner tube 3 and are opposite, the signal receiving unit is connected with a controller through signals, the magnetic attraction structure penetrates through between the signal transmitting unit and the signal receiving unit and is shielded by the signal transmitting unit, the alarm 14 is arranged on the cross tube, and the electromagnet 26 and the alarm 14 are controlled by the controller.
In use, hot air containing iron ore powder enters the transverse pipe 1 through the tank body air outlet pipe 4, enters the outer pipe 2 through the strip groove 5 and moves out of the strip groove 5 on the other side after passing over the strip electromagnet 73, wherein the strip electromagnet 73 can absorb the iron ore powder, so that the iron ore powder is absorbed on the strip electromagnet 73, only hot air flows out, as the iron ore powder is absorbed on the strip electromagnet 73, the overall gravity of the magnetic attraction mechanism 7 is increased, when the overall gravity of the magnetic attraction mechanism 7 is greater than the suction force between the magnet 26 and the iron block 72, the magnetic attraction mechanism 7 falls down and falls on the support rod 12 under the guide of the plunger rod 8, during the falling, the sensor 13 transmits a signal to the controller to control the strip electromagnet 73 to cut off, so that the iron falls off from the strip electromagnet 73 and falls on the support rod 12 of the inner pipe 3 and falls into the ore powder receiving cap 6 under the action of gravity. Since the bar electromagnet 73 is located in the inner tube 3 at this moment, hot air can be effectively prevented from blowing out the iron ore powder to be adsorbed out of the bar-shaped groove 5, so that iron ore powder is collected, then the material receiving cap 6 is opened, the iron ore powder is rapidly poured out, then the material receiving cap 6 is rotated, then the magnetic attraction mechanism 7 is pushed up, so that the iron block 72 is contacted with the magnet 26 and attracts the magnetic attraction mechanism 7, and one of the two iron ore powder adsorption mechanisms still absorbs the iron ore powder when the iron ore powder is removed, so that the number of the iron ore powder entering the heat exchanger is reduced.
Because the magnet mechanism 7 is pushed to the butt joint of the magnet 26 from the inner tube 3 after the iron ore powder is cleaned, the inner tube 3 is in threaded connection with the outer tube 2, so that the inner tube 3 can be moved upwards in a rotating mode on the premise of meeting sealing, the inner tube 3 can be moved to the butt joint of the iron block 72 and the magnet 26, and the magnet 26 is used for adsorbing the magnet mechanism 7. The air inlet 27 is formed in the side face of the outer tube 2 towards the direction of air flow, the air inlet 27 is located above the strip-shaped groove 5, the material receiving cap 6 comprises an outer tube 61, the outer tube 61 is connected to the inner tube 3 in a threaded mode, a material receiving cloth bag 62 is arranged in the outer tube 61, the lower end of the outer tube 61 is sleeved in a sealing disc 63 with the closed bottom end and is connected with the sealing disc 63 in a threaded mode, and when the inner tube 3 rotates in the outer tube 2 to seal the strip-shaped groove 5, the iron block 72 is in contact with the magnet 26. When the inner tube 3 moves upwards, the strip-shaped groove 5 is blocked, when the strip-shaped groove 5 is blocked at the inner tube 3 part, because the strip-shaped groove 5 is positioned on the same transverse line, the air inlet 27 is arranged at one side, so that the air entering the air inlet 27 is little, and even if the air enters the air inlet 27, the air is removed from the strip-shaped groove 5 at the other side, and the air is absorbed by the strip-shaped electromagnet 73 by the iron ore powder, the inner tube 3 rotates upwards, firstly, the strip-shaped groove 5 can be blocked, then the sealing disc 63 is opened, so that the air enters the outer tube 2 through the air inlet 27 and enters the inner tube 3 from the outer tube 2, air flow can be formed in the inner tube 3, the iron ore powder absorbed on the strip-shaped electromagnet 73 is blown away, the iron ore powder is prevented from being absorbed when the magnetism is not generated, the strip-shaped electromagnet 73 can be blown to clean the strip-shaped electromagnet 73 when the magnetic attraction mechanism 7 is pushed to butt joint with the magnet 26, and the iron ore powder is prevented from being adhered to the strip-shaped electromagnet 73.
In the application, two material receiving caps 6 can be arranged on one inner tube 3, so that when the inner tube 3 rotates to the position that the distance between the top surface and the inner wall of the top surface of the strip-shaped groove 5 is 5cm in use, the sealing disc 63 is rotated out, then the inner tube 3 is continuously rotated, the strip-shaped groove 5 is thoroughly sealed by the inner tube 3, the inner tube 3 is positioned below the air inlet 27, after a few seconds of blowing, the inner tube 3 is reversely rotated, when the inner tube 3 rotates to the position that the distance between the top surface and the inner wall of the top surface of the strip-shaped groove 5 is 5cm in use, the sealing disc 63 is rotated again, then the inner tube 3 is continuously rotated, and after the inner tube 3 returns to the initial position, the material receiving caps 6 are integrally removed and replaced with new material receiving caps 6;
Since the bar electromagnet 73 only has a magnetic attraction surface capable of attracting the iron ore powder, the attraction amount is relatively small, and for this reason, the vertical rod 71 is provided with a plurality of bar electromagnets 73 along its circumferential direction with the attraction surfaces of the bar electromagnets 73 facing outward.
