[0029] a cleaning brush 43, the cleaning brush 43 is movably connected to the surface of the threaded block 42;

[0030] an isolation component 5, the isolation component 5 is arranged inside the rectification tank 1;

[0031] a sealing component 6, the sealing component 6 is arranged inside the isolation component 5.

[0032] The function of the filtering component 3 is to filter. The function of the cleaning component 4 is to clean the impurities on the surface of the filtering component 3. The reverse-threaded screw rod 41 is fixedly connected to the surface of the connection groove 31 near the rear end. A rod is fixedly connected to the surface near the front end. Each two threaded blocks 42 are rotatably connected to a cleaning brush 43 and are divided into two groups. At both ends of the cleaning brush 43 in each group are respectively rotatably connected to the surfaces of the two threaded blocks 42. The two threaded blocks 42 are respectively threadedly sleeved on the outer surface of the reverse-threaded screw rod 41 and the surface of the connecting rod on the surface of the connection groove 31. The reverse-threaded screw rod 41 is divided into two threaded sections in opposite directions. One threaded block 42 in each of the two groups is respectively threadedly sleeved on the outer surfaces of the two threaded sections. The top of the reverse-threaded screw rod 41 is fixedly connected to a motor, and the motor is fixedly installed on the outer surface of the top of the rectification tank 1. Thus, starting the motor drives the reverse-threaded screw rod 41 to rotate, and the two threaded blocks 42 respectively drive the two cleaning brushes 43 to move to clean the impurities on the surface of the filtering component 3. The function of the isolation component 5 is to isolate, and the function of the sealing component 6 is to seal. The first partition plate 21 divides the interior of the rectification tank 1 into left and right parts. The rectification pipe 22 is in a loop shape and is fixedly connected to the surface of one end of the connection groove 31. And a plurality of baffle plates are fixedly connected inside the part of the rectification tank 1, thereby increasing the residence time of the condensate in the rectification tank 1 and increasing the rectification efficiency. The connection groove 31 is fixedly connected to the surface of the left end of the first partition plate 21. Many filtering holes are formed on the surface of the filter plate 32. Thus, when the rectification liquid passes through the filter plate 32, the impurities are adsorbed on the surface of the filter plate 32, and the rectification liquid enters the rectification pipe 22 to rectify the cooling liquid.

[0033] The isolation component 5 includes an isolation plate 51. The isolation plate 51 is fixedly connected to the inner surface of the rectification tank 1. One end of the isolation plate 51 is fixedly connected to the surface of the first partition plate 21. A communication port 52 is formed on the surface of the isolation plate 51.

And liquid inlets and outlets are respectively fixedly connected to the top and bottom of the upper and lower parts of the rectification tank 1. The rectification liquid first passes through the upper part and then flows into the interior of the rectification pipe 22 through one end of the rectification pipe 22, then flows to the bottom through the other end, and finally is discharged through the outlet.

[0035] The sealing component 6 includes an adjusting screw rod 61. The adjusting screw rod 61 is movably connected to the interior of the isolation plate 51. A sliding plate 62 is threadedly connected to the outer surface of the adjusting screw rod 61.

[0037] The surface of the sliding plate 62 is provided with a connection port 63, and the sliding plate 62 is movably connected inside the communication port 52.

[0038] When the sliding plate 62 is at the rightmost end of the slot, the sliding plate 62 seals the communication port 52. When the sliding plate 62 moves to the left end and the connection port 63 is inside the communication port 52, the upper and lower parts of the connection groove 31 are connected, and the sewage at the top after cleaning enters the bottom through the connection port 63 and is discharged through the bottom liquid outlet.

[0039] The working principle of the low-temperature rectification equipment of the refrigerator provided by the present utility model is as follows:

[0040] When it is necessary to clean the impurities on the filter plate 32, first start the motor at the top of the reverse-threaded screw rod 41 to drive the reverse-threaded screw rod 41 to rotate. Thus, while the threaded block 42 drives the cleaning brush 43 to move up and down, the cleaning brush 43 contacts the surface of the filter plate 32 and rotates to wash off the impurities on the surface of the filter plate 32. After the cleaning is completed, then rotate the adjusting screw rod 61 to drive the sliding plate 62 to move to the left end until the connection port 63 moves into the interior of the communication port 52. The sewage above the isolation plate 51 flows through the isolation plate 51 to its lower part, and then open the liquid outlet at the lower part of the rectification tank 1, and the sewage is discharged through the liquid outlet. Then, inject new rectification liquid from the liquid inlet at the top of the rectification tank 1.
