[0024] like Figures 1 to 3 As shown, this utility model provides a filtration device for a heat exchanger unit. Liquid enters the interior of the filter tank 100 through the inlet pipe 400 and is filtered by the filter bag 900. The filtered liquid is discharged through the outlet pipe 500. The filtered impurities remain inside the filter tank 100 and can be discharged through the discharge pipe 700. When the filter bag 900 is clogged, the valves on the surface of the outlet pipe 500, the inlet pipe 400, and the discharge pipe 700 are closed, and the valve on the surface of the jet pipe 600 is opened to blow air into the filter tank 100, which can blow off the impurities on the surface of the filter bag 900, making it easy to reuse the filter bag 900.
[0025] like Figures 1 to 4As shown, this utility model provides a filtration device for a heat exchanger unit. The lower end of the connecting seat 910 is provided with an anti-clogging structure. The anti-clogging structure includes a fixing ring 510, which is fixedly installed on the surface of the liquid outlet pipe 500. A movable ring 511 is sleeved on the surface of the liquid outlet pipe 500. A return spring 512, connected to the fixing ring 510 and the movable ring 511, is sleeved on the surface of the liquid outlet pipe 500. A pin 911 is fixedly installed at the upper end inside the connecting seat 910. The upper end of the pin 911 is in contact with the lower end of the movable ring 511.

A rotating gear 327 is rotatably installed inside the mounting ring seat 320. A bevel gear 326 is fixedly installed on one end of the rotating screw sleeve 322. The bevel gear 326 meshes with the rotating gear 327. An adjustment groove 321 is opened at the upper end of the mounting ring seat 320. A push block connected to the rotating gear 327 passes through the interior of the adjustment groove 321.
[0028] like Figures 1 to 3 As shown, this utility model provides a filtration device for a heat exchanger unit. The user pushes the push block, which moves along the adjustment groove 321, causing the rotating gear disk 327 to rotate. The rotating gear disk 327 drives the rotating screw sleeve 322 through the bevel gear 326. Under the action of the thread, the limiting screw 323 moves into the interior of the rotating screw sleeve 322, causing the locking block 325 to be pulled out from the inside of the locking groove 311 and disengaged from the connecting block 310. This allows the canister cover 300 to be disengaged from the filter canister 100, thereby facilitating the cleaning of the interior of the filter canister 100.
