[0007] In a further technical solution, a plurality of second blowdown holes are provided on the bottom plate, and a filter screen is provided in each second blowdown hole.
[0008] A further technical solution is that the aperture sizes of the filter screen, protective screen, and filter holes decrease sequentially.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] The coarse brine to be filtered enters the filter chamber through the inlet, passes through the protective mesh into the filter cylinder, and after filtration, flows from the inside of the filter cylinder to the seepage outlet, and finally exits from the outlet at the top of the outer shell. The entire process, with the coarse brine entering from the bottom and exiting from the top, facilitates the flushing of impurities on the bottom plate, the lower end of the top plate, the outside of the filter cylinder, and the protective mesh, preventing impurities from accumulating and causing blockages. This avoids the problem of large impurities leaking from the filter chamber and the need for frequent filter cleaning. Attached Figure Description
