Description

Technical Field

[0001] The invention relates to the technical field of dryers, and in particular to a dryer with a refrigerant leakage early warning function. Background Art

[0002] Cold dryer is the abbreviation of refrigerated dryer. It is a new technology and belongs to the air source processing component in the pneumatic system. It uses refrigerant to exchange heat with compressed air to reduce the temperature of compressed air to the dew point temperature in the range of 2 to 10℃. In the patent application with application announcement number CN220871272U, it includes that the outer surface of the movable sleeve of the main case is fixedly installed with a placing plate, and the adjusting component includes a movable plate, the movable plate is arranged on one side of the placing plate, and the outer surfaces of multiple placing plates are fixedly installed with clamping columns, and multiple clamping grooves are opened inside the movable plate, and the clamping columns are movably clamped inside the clamping grooves. The utility model drives the anti-slip plate to move back and forth inside the installation groove by controlling the extension and retraction of the electric telescopic rod. During the movement of the movable plate, the placing plates at both ends are driven to move one downward and the other upward. Conversely, the anti-slip plate will be driven to move in the opposite direction inside the installation groove. Under the action of the clamping groove, the placing plates at both ends move in opposite directions, thereby achieving the purpose of synchronously adjusting the spacing between multiple placing plates.

[0018] A conical groove is provided on the guide hopper 22 , and a connecting hole is provided on the guide hopper 22 below the conical groove. The cross section of the guide hopper 22 is in a “Y” shape.

[0019] An inner baffle is fixedly provided at the bottom of the guide hopper 22, and the bottom end of the floating plate 23 contacts the top of the inner baffle. An outer baffle is fixedly provided on the inner wall of the collecting tank body 21, and the bottom end of the floating plate 23 contacts the top of the outer baffle. A plurality of volatilization holes are opened on the floating plate 23, and the plurality of volatilization holes are distributed in a circular array.

[0020] The first conductive sheet 241 and the second conductive sheet 242 are symmetrically arranged with respect to the connecting conductive sheet 232 . One end of the lower material guiding pipe 25 is connected to the inside of the electromagnetic valve 243 . The cooling pipe 26 is vortex-shaped.

[0021] When leakage occurs at the connection between the feed inlet 17 and the second feed guide tube 162, the liquid refrigerant and the mixed gas inside will enter the collection tank body 21 through the inclined surface of the guide hopper 22. As the refrigerant inside the collection tank body 21 gradually increases, the float plate 23 can slide on the inner wall of the collection tank body 21 under the action of its own buoyancy, and the side plate 231 fixed on the float plate 23 can slide on the inner wall of the movable groove.

At the same time, the first material guide pipe 161 can be connected to the lower material guide pipe 25. At this time, the gas mixed with the refrigerant can enter the lower material guide pipe 25 through the first material guide pipe 161, and then enter the cooling pipe 26. At this time, the refrigerant in the collection tank body 21 can cool the gas in the cooling pipe 26, and finally be discharged into the evaporator body 12 through the upper material guide pipe 27, so as to fully utilize the leaked refrigerant.

[0022] A sealing assembly 3 is provided at the top of the collecting tank body 21, and the sealing assembly 3 includes two expansion side seats 31 fixed at the top of the collecting tank body 21, and an expansion airbag 34 is fixedly provided inside each expansion side seat 31.

[0024] The dryer body 1 is provided with a main air inlet 14 , the dryer body 1 is provided with a main air outlet 15 on one side of the main air inlet 14 , and the dryer body 1 is provided with a radiator 13 on the other side of the evaporator body 12 .

[0025] When leakage occurs at the connection between the feed port 17 and the second feed guide pipe 162, the liquid refrigerant and the mixed gas inside will enter the collection tank body 21 through the inclined surface of the feed guide hopper 22. With the cooperation of the early warning adjustment component 2, the refrigerant inside the collection tank body 21 can absorb the temperature of the surface of the cooling tube 26. The refrigerant that has absorbed a certain amount of heat will volatilize. At this time, the space below the feed guide hopper 22 is in a sealed state, and the volatilization of the refrigerant can increase the air pressure in the sealed space. The volatilized refrigerant can enter the two air guide pipes 33 through multiple air inlets 32, and finally enter the expansion airbag 34 fixed on each expansion side seat 31, and cause the expansion airbag 34 to expand, so as to seal the refrigerant leakage position connected between the feed port 17 and the second feed guide pipe 162, thereby playing a sealing role.

[0026] The working principle and use process of the present invention are as follows: when leakage occurs at the connection between the feed inlet 17 and the second material guide pipe 162, the liquid refrigerant and the mixed gas inside thereof will enter the interior of the collecting tank body 21 through the inclined surface of the material guide hopper 22. As the refrigerant inside the collecting tank body 21 gradually increases, the float plate 23 can slide on the inner wall of the collecting tank body 21 under the action of its own buoyancy, and the side plate 231 fixed on the float plate 23 can slide on the inner wall of the movable groove. During this process, the connecting conductive sheet 232 fixed on the side plate 231 can contact the first conductive sheet 241 and the second conductive sheet 242 at the same time. At this time, the power supply can energize the warning buzzer 24 and the solenoid valve 243 through the connection of the wires, so that the warning buzzer 24 sounds an alarm. At this time, the solenoid valve 243 can automatically close the passage of the first material guide pipe 161 to the second material guide pipe 162, and at the same time, the first material guide pipe 161 can be connected to the lower material guide pipe 25. At this time, the gas mixed with the refrigerant can enter the lower guide pipe 25 through the first guide pipe 161, and then enter the cooling pipe 26. At this time, the refrigerant in the collecting tank body 21 can cool the gas in the cooling pipe 26, and finally be discharged into the evaporator body 12 through the upper guide pipe 27. At the same time, the refrigerant in the collecting tank body 21 can absorb the temperature of the surface of the cooling pipe 26. The refrigerant that has absorbed a certain amount of heat will volatilize. At this time, the space below the guide hopper 22 is in a sealed state, and the volatilization of the refrigerant can increase the air pressure in the sealed space. The volatilized refrigerant can enter the two air guide pipes 33 through multiple air inlets 32, and finally enter the expansion airbag 34 fixed on each expansion side seat 31, and make the expansion airbag 34 expand, so as to seal the refrigerant leakage position connected between the feed port 17 and the second guide pipe 162.
