[0019] The outer wall of the lower tank body 100 is provided with a feed inlet 110, and the other side wall of the lower tank body is provided with a discharge outlet 120. A partition plate 130 is installed at the bottom of the lower tank body 100. Two blowdown pipes 140 are symmetrically arranged at the bottom of the lower tank body 100 with the partition plate 130 as the center. A first threaded sleeve 150 is installed at the top of the feed inlet 110. A second threaded sleeve 210 is installed at the bottom of the upper tank body 200. A connecting tank body 300 is located between the lower tank body 100 and the upper tank body 200. A second threaded groove 310 is formed at the top of the connecting tank body 300 and matched with the second threaded sleeve 210. A first threaded groove 320 is formed at the bottom of the connecting tank body 300 and matched with the first threaded sleeve 150. By connecting the first threaded sleeve 150 and the first threaded groove 320, and connecting the second threaded sleeve 210 and the second threaded groove 310, the upper tank body 200, the connecting tank body 300 and the lower tank body 100 are connected from top to bottom to form an overall filter tank structure. In use, the slurry enters the inside of the lower tank body 100 through the feed inlet 110. At this time, the flow rate of the slurry will gradually decrease. The particles in the slurry will settle to the bottom of the filter tank under the action of gravity. The particles with higher density are more likely to quickly precipitate to the bottom of the filter tank under the influence of gravity, realizing the separation of the slurry and the particles. The filtered slurry is discharged through the blowdown outlet 140. The blowdown outlet 140 is a tubular structure and is provided with a ball valve inside. When it is necessary to blow down the inside of the filter tank, the ball valve is opened, and the dirt can be discharged from the blowdown outlet 140.

The other ends of the two limiting rods 440 respectively extend through the top and bottom of the fixing frame 410. When the connecting tank body 300 is connected with the lower tank body 100, the sliding plate 420 is pulled to slide upward in the fixing frame 410 and press the upper spring 430. The lower limiting rod 440 is retracted into the fixing frame 410 along with the sliding plate 420. At this time, the lower tank body 100 is connected with the connecting tank body 300 by rotating the first threaded sleeve 150 and connecting the first threaded groove 320.

When the clamp 170 is installed, the clamp 170 is deformed by being squeezed, and the fixed pipe 170a is inserted into the discharge port 120. The clamp 170 is released and clamped on the inner wall of the lower tank body 100 to fix the fixed pipe 170a in the discharge port 120.
