Background technology
It is connected respectively with carbon-dioxide gas compressor and process tank before and after the main evaporator of refrigerator of expansion line cold end, carries
Task by the carbon dioxide liquefaction of 40 DEG C, 32bar-35bar pressure for liquid.
Because the particularity of carbon dioxide process flow, the carbon dioxide through compressor compression carries a certain amount of
Moisture, these moisture with carbon dioxide in evaporator of refrigerator by the freezing of freon, become ice, these ice are gradual
Evaporator inner silica carbon path and flange are blocked, carbon-dioxide gas compressor outlet pressure is ultimately resulted in and is alarmed more than setting value
Parking.So needing periodically (accumulative production 50 hours) to be dismantled by maintenance mans to evaporator, remove in evaporator both ends and gather
Water.
Needed however, each quality of the flange at evaporator both ends is more in 90kg or so, each maintenance by 3 staff
Synchronous working is just basically completed for time-consuming 6 hours, therefore the situation that evaporator ice blocks up largely is influenceing production line just
Often operation.
Therefore, it is necessary to existing evaporation structure is improved, to solve the above problems.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided one kind solves to expand main evaporator of refrigerator
Ice stifled structure and method.The present invention makes it can be with by being improved on the basis of existing main evaporator of refrigerator structure
High pressure gas is passed through, to realize cleaning accumulated ice rapidly and efficiently.
In order to reach above-mentioned purpose, the present invention adopts the following technical scheme that：
It is a kind of to solve to expand the stifled structure of main evaporator of refrigerator ice, including evaporator body, the both ends of evaporator body
With end flange, there is plug installing port in one of end flange；
There is carbon dioxide pipe, carbon dioxide pipe and the condenser pipe inside evaporator body on evaporator body
Beam is connected, and condensation tube bank connects with carbon dioxide liquid back pipe；
And there is gas-liquid dividing plate inside evaporator body,
Inlet suction port is additionally provided with the evaporator body, inlet suction port is connected with condensation tube bank；
Air outlet valve is installed, and the end flange of evaporator body is provided with sewage draining exit on the plug installing port；
Wherein, compressed air melts accumulated ice through pervaporation device body interior after inlet suction port entrance, and accumulated ice is changed into liquid
Water flows out from sewage draining exit.
Preferably, the inlet suction port is connected by counter flange with condensation tube bank.
Preferably, the counter flange center has gas channel, has the pilot hole of hierarchic structure on the outside of gas channel
And the pilot hole of cylindrical structure.
Preferably, the air outlet valve is manual ball valve.
While said structure scheme is provided, present invention also offers a kind of side that accumulated ice is removed using said apparatus
Method, mainly comprise the following steps：
A, air outlet valve and sewage draining exit are opened, makes vaporizer body form open circuit；
B, compressed air is made to enter from inlet suction port；
C, compressed air is melted the accumulated ice condensed inside tube bank and end flange using the heat and kinetic energy of itself；
D, accumulated ice becomes sewage from sewage draining exit outflow；
E, sewage draining exit and air outlet valve are closed, completes accumulated ice cleaning.
In the above method, it is preferred that step D continues 15-20 minutes.
The beneficial effects of the invention are as follows：
Entered using compressed air from intake valve, flowed out after flowing through evaporator body inside from air outlet valve so that evaporator sheet
The ice-out of body accumulated inside is the water of liquid, is then flowed out from sewage draining exit.Whole process efficient quick, and without dismantling evaporation
Device flange, and then manual working intensity is reduced, and reduce downtime.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment：As shown in figure 1, a kind of solve to expand the stifled structure of main evaporator of refrigerator ice, including evaporator body
10, the east of evaporator body 10 is connected with evaporator east flange 1, and western end is connected with evaporator Western method orchid 7, evaporator sheet
10 have carbon dioxide pipe 2, carbon dioxide liquid back pipe 4 and plug installing port on body, and the inside of evaporator body 10 has cold
Solidifying tube bank 6 and gas-liquid dividing plate 5.
The side of evaporator east flange 1 is additionally provided with inlet suction port 3, and inlet suction port 3 is installed on evaporator body 10 on the lower
Part, the inner side of inlet suction port 3 are connected by counter flange 11 with condensation tube bank 6.As shown in Figures 2 and 3, in the counter flange 11
Centre has gas channel 12, and the outside of gas channel 13 has the pilot hole 13 of hierarchic structure and the pilot hole 13 of cylindrical structure, real
Show and utilized replacement of the counter flange 11 by connector by non-standard to standard component.
Air outlet valve 9 is installed, and the end flange of evaporator body 10 is provided with sewage draining exit 8 on the plug installing port.
Under use state, inlet suction port 3 is connected by intake valve with the pneumatics source of the gas of outside.
The present invention principle be：The 3/4 〞 plugs installed on original plug installing port are replaced with into this of pressure-resistant 100bar
Paisa gram manual ball valve (i.e. air outlet valve 9), and additionally increase inlet suction port 3 on evaporator body 10, make evaporator body 10
Inside is also provided with an air inlet and a gas outlet while with original structure.
Under normal operating condition, flange, air outlet valve 9 and sewage draining exit 8 on inlet suction port 3 are on state, titanium dioxide
Carbon gasifies in the freon that condensation is restrained outside the tube bank 6 that is condensed inside 6 and cooled, and is normally liquefied, while produced with accumulated ice.
When shutting down cleaning accumulated ice, open air outlet valve 9 and sewage draining exit 8, compressed air and enter from inlet suction port 3, using itself
Kinetic energy and temperature, flow through the process that 6, evaporator east flange 1 and evaporator Western method orchid 7 are restrained in the condensation inside evaporator body 10
In, the accumulated ice inside evaporator body 10 is converted into water, flowed out from sewage draining exit 8 as liquid.Melt the early stage of accumulated ice, because of sky
Pressure of compressed air is larger, so compressed air can flow out from air outlet valve 9, until after the middle and later periods, accumulated ice (the i.e. liquid after and more melting
State water) together discharged from sewage draining exit 8, and then ensure that initial charge state downstream passage is unimpeded.Continue to evaporator body
Ventilation 15 minutes or so in 10, you can melt most of accumulated ice, so as to quickly finish the maintenance work of evaporator body 10.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
