[0024] The self-locking mechanism 9 includes a sliding plate 14, one side of the sliding plate 14 is fixedly connected to a self-locking block 15, and the other side of the sliding plate 14 is centrally fixedly connected to a group of self-locking springs 16, and the other side of the sliding plate 14 is fixedly connected to a pull rod 17 on the side. In order to facilitate the replacement of the inner tank and the cleaning of the filtered impurities, the self-locking mechanism 9 is provided.

[0025] See also Figure 1The heat exchange box 1 is located on one side of the cleaning liquid tank 2. The upper and lower ends of the heat exchange box 1 are fixedly connected with an inlet pipe and a return pipe. One end of the inlet pipe is fixedly connected to the one-way valve 5, and one end of the return pipe is fixedly connected to the filter barrel 3. Start the circulation pump 4 and the one-way valve 5, extract the cleaning liquid inside the cleaning liquid tank 2, and transport it to the inside of the heat exchange box 1 through the inlet pipe, so that it flows along the pipeline inside the heat exchange box 1, and then enters the filter barrel 3 through the return pipe.

[0026] See also Figure 2 One side of the filter liner 7 is arranged in an inclined shape, and the clamping ring 13 is centered with the bottom surface of the filter liner 7 and is clamped. The cleaning liquid entering the filter barrel 3 is filtered through the filter liner 7, so that impurities are filtered inside the filter liner 7, and the cleaning liquid flows back into the cleaning liquid tank 2.

[0027] See also Figure 2 The side of the cleaning rod 12 is arranged in an inclined shape, and one end of the cleaning rod 12 is in contact with the inner surface of the filter liner 7.
