Embodiment, as shown in Figures 1 to 3, a tank body for a thickener, including an outer cylinder 10 and a guide tube 20, the upper part of the outer cylinder 10 is fixed with an end cover 1, and the guide tube 20 is inserted Covered in the outer cylinder 10 and fixed on the inner side wall of the outer cylinder 10 by the support rod 21, the bottom end side wall of the guide tube 20 is formed with an extension 22 extending radially outward, and the extension 22 is fixed on the outer cylinder 10 On the inner side wall of the outer cylinder body 10 and the guide cylinder 20, an external elutriation area 30 and an inner elutriation area 40 are formed. It communicates with the external elutriation area 30, and the upper side wall of the outer cylinder 10 is connected with an overflow pipe 6;

Further, the inner wall of the guide cylinder 20 is fixed with a limit ring 2, the filter cartridge 3 is inserted into the guide cylinder 20, the lower end surface of the filter cartridge 3 is pressed against the limit ring 2, and the top of the filter cartridge 3 The filter device 31 is fixed, the top compression ring 32 is inserted into the guide tube 20 and fixedly connected to the inner side wall of the guide tube 20 by bolts, the top compression ring 32 is pressed against the top surface of the filter device 31 .

Further speaking, the lower end of the outer cylinder 10 is a tapered portion 50, the lower end of the tapered portion 50 is connected with a collecting portion 60, and the lower end of the collecting portion 60 is formed with a recoil port 70, and the collecting portion 60 The side wall has an outlet opening 80 .

Further speaking, the upper end of the end cover 1 is connected with two window holes 12 , and a window mirror is fixed on the window holes 12 .

Further, the filter cartridge 3 includes a frustum-shaped cylindrical body 301 made of a porous plate. The bottom outer wall has a bottom filter plate 303 made of a porous plate, a first filter plate 304 and a second filter plate 305 are welded and fixed on the middle outer wall of the cone-shaped cylinder 301, and the bottom filter plate 303 is pressed against the limit ring 2, The outer walls of the top filter plate 302 , the bottom filter plate 303 , the first filter plate 304 and the second filter plate 305 are all in close contact with the inner wall of the guide tube 20 .

Further speaking, the cavity between the first filter plate 304 and the second filter plate 305 is filled with a mesh filter block 306 formed by stacking multiple layers of mesh plates.

Further, the filter device 31 includes an annular porous bottom plate 311, the annular porous bottom plate 311 has a main annular groove 312, the main annular groove 312 is filled with gravel 313, the porous cover plate 314 is fixed on the annular porous bottom plate 311, the top The pressing ring 32 is pressed against the perforated cover plate 314 .

Further, the side wall of the exhaust pipe 5 is connected with an inflatable pipe 51, the upper end of the inflatable pipe 51 is connected with the exhaust end of the air pump 52, and the air pump 52 is fixed on the connecting plate 101 fixed on the outer wall of the outer cylinder 10.
