[0035] With reference to Figure 4 One end of return spring 65 is fixedly connected on the top of dredging ball 66 outer wall, the other end of return spring 65 is fixedly connected on the top of scraper 64 inner wall, the effect of return spring 65 is to automatically reset the position of the bottom of dredging ball 66 after extrusion movement, dredging ball 66 slidingly connects on the inner wall of scraper 64, the surface of filter plate 7 is provided with multiple filter holes, the outer wall of dredging ball 66 is in contact with the inner wall of filter hole, the contact between the two, so that scraper 64 can dredge filter hole of filter plate 7 through dredging ball 66 when moving, so as to avoid the blockage when filtering the sandstone in the hot water of geothermal, thereby affecting the filtering efficiency of sandstone.

[0036] With reference to Figure 4 And Figure 5The switching assembly 5 comprises a moving rod 51, a plurality of clamping grooves are formed in the surface of the moving rod 51, the bottom end of the outer wall of the plug block 54 is clamped with the inner wall of the clamping groove, and the clamping is achieved between the two, so that the moving rod 51 can drive the shielding plate 52 to adjust the two groups of positions communicated with the drain pipes 4 in the inner wall of the shell 1 to be closed, thereby facilitating the hot water to discharge the sand outward, and when one of the drain pipes 4 is blocked and damaged, the switching can be performed in time, so that the machine does not need to be stopped for maintenance.
