[0015] The beneficial effects of the present invention are: 1.

[0016] 2. The filter cartridge is driven by a motor to rotate, so that the discharge port and the second discharge pipe are rotated to the bottom of the first discharge pipe, so that the muddy debris enters the filter cartridge. The filter cartridge is driven by a motor to rotate at a high speed, so that the residual water in the muddy debris is thrown out to the inner wall of the guide box and flows into the collecting box. After the muddy debris is dehydrated to form dry residue, it enters the discharge mechanism and is finally discharged.

[0017] 3. The transmission shaft is driven to rotate by the second reduction motor, so that the arc filter and the square filter are fitted on the inner wall of the primary treatment box with the central axis of the transmission shaft as the center and rotate in a circle. While the arc filter and the square filter rotate, the waste liquid in the primary treatment box is fully filtered. The larger particles of impurities and flocs in the waste liquid remain on the surface of the square filter, and the smaller particles of muddy debris in the waste liquid pass through the square filter and enter the arc filter. The device can simultaneously perform graded filtration on the waste liquid, and make the arc filter and the square filter fully contact with the waste liquid, effectively improving the filtration effect and effectively avoiding the situation where impurities sink to the bottom and cannot be filtered.

[0018] 4. The first reduction motor drives the transmission gear to rotate, so that the incomplete gear ring drives the linkage rod to rotate clockwise, so that the two sets of linkage rods drive the transmission shaft to rotate on the surface of the two sets of arc guide rails. At the same time, the second reduction motor drives the transmission shaft to rotate counterclockwise, so that the opening of the arc filter is always facing upward to prevent the muddy debris in the arc filter from flowing out, thereby effectively improving the stability of the muddy debris during transportation and preventing the muddy debris from flowing out and causing environmental pollution.

When the dehydration mechanism 10 completes dehydration and needs to remove material residues, the electric turntable 11 drives the material guide cylinder 1201 to rotate, so that the feed port 1202 rotates to the top, so that the material residues can enter the material guide cylinder 1201 through the feed port 1202. The fourth reduction motor 1204 drives the feed shaft 1205 to rotate, so that the second spiral material guide blade 1206 rotates and transports the material residues, so that the material residues are discharged through the second discharge pipe 13 and collected for recycling.

While the arc filter 705 and the square filter 706 rotate, the waste liquid in the primary treatment box 1 is fully filtered, and the larger particles of impurities and flocs in the waste liquid remain on the surface of the square filter 706, and the smaller particles of muddy debris in the waste liquid pass through the square filter 706 and enter the arc filter 705.

[0032] When the square filter 706 rotates to the first discharge pipe 101, the larger granular impurities and flocs accumulated on the square filter 706 are discharged through the first discharge pipe 101 for collection and centralized treatment, and the filter mechanism 7 continues to rotate until it is level with the opening of the primary treatment box 1. At this time, the electric valve plate is opened to open the guide groove 105, and the filtered waste liquid enters the liquid collection box 202 through the square guide pipe 3 for further treatment.

[0033] The first reduction motor 107 drives the transmission gear 108 to rotate, so that the incomplete gear ring 106 drives the linkage rod 104 to rotate clockwise, so that the two sets of linkage rods 104 drive the transmission shaft 701 to fit on the surface of the two sets of arc guide rails 6 to rotate.

After the muddy debris in the arc filter 705 is emptied, the filter mechanism 7 is driven by the first reduction motor 107 and the second reduction motor 702 to reset to the initial state, and start the next round of filtering operation.

[0034] The filter cartridge 1004 is driven to rotate by the motor 5, so that the discharge port 1005 and the second discharge pipe 17 are rotated to the bottom of the first discharge pipe 8, so that the muddy debris enters the filter cartridge 1004, and the filter cartridge 1004 is driven to rotate at a high speed by the motor 5, so that the residual water in the muddy debris is thrown out to the inner wall of the guide box 201 and flows into the collecting box 202. The muddy debris is dehydrated to form dry residue. The filter cartridge 1004 is driven to rotate by the motor 5, so that the discharge port 1005 and the second discharge pipe 17 are rotated to the top of the discharge mechanism 12, and the two groups of first spiral guide blades 1007 are driven to rotate synchronously by the third reduction motor 1008, so that the residue attached to the inner wall of the filter cartridge 1004 is transported to the center of the filter cartridge 1004 until it is transported to the discharge port 1005 for discharge.

[0035] When the dehydration mechanism 10 is in a dehydration state, the electric turntable 11 drives the material guide cylinder 1201 to rotate, so that the feed port 1202 rotates to the bottom to prevent water generated by dehydration from flowing out of the material guide cylinder 1201. When the dehydration mechanism 10 completes dehydration and needs to remove material residues, the electric turntable 11 drives the material guide cylinder 1201 to rotate, so that the feed port 1202 rotates to the top, so that the material residues can enter the material guide cylinder 1201 through the feed port 1202. The fourth reduction motor 1204 drives the feeding shaft 1205 to rotate, so that the second spiral material guide blade 1206 rotates and transports the material residues, so that the material residues are discharged through the second discharge pipe 13 and collected for recycling.

[0036] Based on the above-mentioned advanced environmentally friendly waste liquid treatment device for building materials, the embodiment of the present invention further proposes a treatment method for the waste liquid treatment device. Exemplarily, the treatment method includes: Pour the waste liquid to be treated and the flocculant into the primary treatment tank for full reaction; Turn on the second reduction motor, and the arc filter and the square filter fit on the inner wall of the primary treatment box and rotate to fully filter the waste liquid in the primary treatment box; Larger particles of impurities and flocs in the waste liquid remain on the surface of the square filter, while smaller particles of muddy debris in the waste liquid pass through the square filter and enter the arc filter; When the square filter screen rotates to the first discharge pipe, the larger particles and flocs accumulated on the square filter screen are discharged through the first discharge pipe; When the filter mechanism continues to rotate until it is level with the opening of the primary treatment box, the electric valve plate is opened to allow the filtered waste liquid to enter the liquid collection box through the square guide pipe; Turn on the first reduction motor to drive the transmission shaft to rotate against the surfaces of the two sets of arc guide rails; Turn on the second reduction motor to drive the transmission shaft to rotate counterclockwise so that the opening of the arc filter always faces upward; When the filter mechanism rotates to the top of the hemispherical funnel, the second reduction motor is turned on to drive the transmission shaft to continue to rotate counterclockwise, so that the arc filter and the square filter are synchronously fitted and rotated between the two sets of limit plates, so that the muddy debris in the arc filter flows out through the square filter into the hemispherical funnel; The motor is turned on to drive the filter cartridge to rotate, so that the discharge port and the second discharge pipe are rotated to the bottom of the first discharge pipe, and the first solenoid valve and the second solenoid valve are turned on to allow the muddy debris to enter the filter cartridge; Turn on the motor to drive the filter cartridge to rotate at high speed, so that the residual water in the muddy debris is thrown out and flows into the liquid collection box; After the muddy debris is dehydrated, it forms dry slag. The motor is turned on to drive the filter cartridge to rotate, so that the discharge port and the second discharge pipe rotate to the top of the discharge mechanism. The third reduction motor is turned on to drive the two sets of first spiral guide blades to rotate synchronously, so as to transport the residue attached to the inner wall of the filter cartridge to the center of the filter cartridge until it is transported to the discharge port and discharged; Turn on the electric turntable to drive the guide barrel to rotate, so that the feed port rotates to the top, and turn on the second solenoid valve to allow the slag to enter the guide barrel through the feed port; The fourth reduction motor is turned on to drive the feeding shaft to rotate, so that the second spiral guide blade rotates and transports the material residue, so that the material residue is discharged through the second discharge pipe.
