A plurality of through holes are provided on the bottom plate of the first fixed groove 211 close to the water outlet 13 to allow the filtrate filtered by the fine filter plate 213 to flow out. The coarse filter plate 212 and the fine filter plate 213 are both fixed in the first fixed groove 211 and abut against the four side walls of the first fixed groove 211 to filter the waste liquid entering from the water inlet 12. The coarse filter plate 212 is located on a side of the fine filter plate 213 close to the water inlet 12, and the filter hole density of the coarse filter plate 212 is greater than the filter hole density of the fine filter plate 213, which is convenient for multiple filtration of wastewater to obtain a better filtering effect.

[0025] The second filter component 22 includes a second fixed groove 221, an activated carbon filter layer 222 arranged in the second fixed groove 221, a quartz sand filter layer 223 arranged adjacent to the activated carbon filter layer 222, and a cotton yarn layer 224 arranged adjacent to the quartz sand filter layer 223.

[0026] The second fixing groove 221 is inserted from the inspection port 14 and abuts against the other three side walls of the housing 11. At the same time, since the internal filter layer is heavy, it can be inserted by opening a groove or setting a convex strip inside the housing 11, and no further restrictions are made here. The activated carbon filter layer 222, the quartz sand filter layer 223 and the cotton yarn layer 224 are stacked in sequence, and the arrangement is from the water inlet direction where the water inlet 12 is located to the water outlet direction where the water outlet 13 is located, the cotton yarn layer 224, the quartz sand filter layer 223, and the activated carbon filter layer 222 are arranged in sequence, so that various particulate matter in the wastewater can be adsorbed through the cooperation between the multiple filter layers to achieve further filtration.

The first fixed cover plate 312 is disposed between the first support plate 311 and the second support plate 313, and is sized to completely cover the inspection port 14. It is conceivable that the first fixed cover plate 312 is also provided with a handle for easy holding, and a sealing strip disposed on the contact surface with the shell 11, which are all conceivable prior arts, so only a brief description is given here. The L-shaped top plate 314 is a long strip top plate with an L-shaped cross section, which abuts against and buckles on the first fixed cover plate 312 to limit the first fixed cover plate 312 and prevent displacement.

The sliding sleeve 334 is sleeved on the sleeve rod 333 and can slide freely along the rod body. The sliding sleeve 334 is fixedly connected to the L-shaped clamping plate 335 so that the sliding sleeve 34 can drive the L-shaped clamping plate 335 to move when it moves. The L-shaped clamping plate 335 is a long strip top plate with an L-shaped cross-section, which is pressed against and buckled on the filter layer to clamp and fix the position of the filter layer. The threaded rod 336 passes through the second placement plate 332 and is threadedly connected, and the end is fixed on the L-shaped clamping plate 335, so that the L-shaped clamping plate 335 can be driven to move by rotating the threaded rod 336 to fix the filter layer.

[0033] When in use, firstly, waste water is put into the shell 11 through the water inlet 12, and the waste water is filtered through the coarse filter plate 212 and the fine filter plate 213, and then the waste water falls and passes through the cotton yarn layer 224, the quartz sand filter layer 223 and the activated carbon filter layer 222 in turn, and the microbial impurities in the waste water are adsorbed, and the treated waste water flows out through the water outlet 13 for recycling and reuse. After the work is completed, the first fixing groove 211 is separated from the shell 11 by rotating the fastener, and the L-shaped top plate 314 is pushed upward, the spring 316 is compressed, and the telescopic rod 315 is contracted, so that the bottom end of the L-shaped top plate 314 is separated from the first fixed cover plate 312, and the The first fixed cover plate 312 removes the first fixed groove 211, cleans the coarse filter plate 212 and the fine filter plate 213 in the first fixed groove 211, separates the second fixed cover plate 321 from the shell 11 by rotating the fastening screw 322, pulls the second fixed cover plate 321 to remove the second fixed groove 221, and rotates the two threaded rods 336 to drive the second L-shaped plate 22 to move. The sliding sleeve 25 on the second L-shaped plate 22 slides on the sleeve rod 26, and the L-shaped clamping plate 335 moves upward, thereby removing the cotton yarn layer 224, the quartz sand filter layer 223 and the activated carbon filter layer 222 for replacement.

[0034] Compared with the prior art, the concrete wastewater filtration equipment provided by the utility model realizes multiple filtration of wastewater and layered filtration of different impurities by setting the coarse filter plate 212 and the fine filter plate 213, and utilizes different filter hole densities to obtain better filtration effect. Through the cooperation between the L-shaped top plate 314, the spring 316 and the telescopic rod 315, the first fixed groove 211 is fixed and disassembled, so that the coarse filter plate 212 and the fine filter plate 213 can be taken out for cleaning. At the same time, by setting the threaded rod 336 to rotate and drive the L-shaped clamping plate 335, the cotton yarn layer 224, the quartz sand filter layer 223 and the activated carbon filter layer 222 are fixed and disassembled, so that the filter layer can be removed for replacement, and the equipment can be used multiple times, saving equipment costs.
