Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a building construction sewage filter. Background Art

[0002] At present, construction needs to treat the sewage generated during construction. Generally, the sewage is mixed with mud, iron nails and iron sheets. The sewage is rich in construction impurities and harmful substances. Direct discharge will damage the surface water quality and ecological environment near the construction site.

[0003] A Chinese utility model patent with announcement number CN211885744U discloses a construction sewage filter, comprising an outer shell, a side wall of which is provided with a water inlet, a first guide plate fixedly connected to the inner side of the outer shell, a second guide plate fixedly connected to the inner side of the outer shell, an upper mounting ring provided at the lower end of the outer shell, a detachable inner shell provided inside the outer shell, a lower mounting ring provided on the lower side of the inner shell, and a mounting mechanism provided between the upper mounting ring and the lower mounting ring.

[0004] Although the above-mentioned prior art can quickly realize the disassembly and assembly operation between the outer shell and the inner shell, facilitate the cleaning of the coarse filter, and filter out harmful substances in the sewage, the filter screen and filter filler alone cannot fully filter the sewage, and there will be water-soluble pollutants, which reduces the filtering effect. Utility Model Content

[0005] In order to solve the technical problem that sewage cannot be fully filtered, pollutants soluble in water exist and the filtering effect is reduced, the utility model provides a construction sewage filter.

[0006] The utility model is implemented by the following technical scheme: a construction sewage filter, comprising a sedimentation tank and a filter tank, the filter tank is connected with the sedimentation tank through a water pump, an inlet is opened at the top of the sedimentation tank, and an interception component is arranged inside the sedimentation tank for intercepting large-grained concrete blocks and construction metal debris, a sedimentation part is arranged at the bottom of the sedimentation tank and below the interception component, a filtering mechanism is arranged inside the filter tank for fully filtering the sewage after sedimentation, and a water outlet pipe is connected to one side of the filter tank.

[0007] As a further improvement of the above scheme, the filtering mechanism includes a filter box fixedly installed inside the filter pool, a rotating shaft is rotatably installed inside the filter box, and the interior of the filter box is filled with activated carbon particles, and rotary blades are fixedly installed on the surface of the rotating shaft.

[0008] Through the above technical solution, the water flow flushes the rotary blades, so that the rotary blades drive the rotating shaft to rotate, thereby rotating and stirring the activated carbon particles, so that the activated carbon particles can fully filter the sewage and improve the filtering effect.

[0009] As a further improvement of the above scheme, eccentric disks are fixedly connected to both ends of the rotating shaft, a through groove corresponding to the eccentric disk is opened at the bottom of the filter box, and a filter plate sliding inside the filter tank is arranged at the bottom of the filter box, a second spring is fixedly installed at the bottom of the filter plate, and the filter plate and the eccentric disk are arranged correspondingly, and the second spring is fixedly installed on the inner wall of the filter tank.

[0010] Through the above technical solution, the rotation of the rotating shaft drives the eccentric disk to rotate at the same time, so that the eccentric disk squeezes the filter plate. By cooperating with the second spring, the filter plate slides up and down to prevent sand and gravel particles from clogging the filter plate. At the same time, the filter plate is arranged at the bottom of the filter box. When the eccentric disk is not in contact with the filter plate, the filter plate blocks the through groove to prevent the activated carbon particles from leaking out.

[0011] As a further improvement of the above solution, the interception assembly includes a mounting plate slidably connected to the top of the sedimentation tank, and an interception net is arranged inside the mounting plate.

[0012] Through the above technical solution, larger particles of concrete or iron sheets and wires are intercepted by the interception net to prevent such debris from affecting the normal use of the device.

[0013] As a further improvement of the above solution, the intercepting net is detachably arranged, and a first spring is fixedly connected to the bottom of the mounting plate, and the first spring is fixedly mounted on the inner wall of the sedimentation tank.

[0014] Through the above technical solution, the first spring performs buffering when the interception net is intercepting, thereby preventing heavier debris from damaging the interception net.

[0015] As a further improvement of the above solution, the water pipe of the water pump is located above the sedimentation part, and the water pipe on the other side of the water pump leads to the top of the filter tank, and the incoming water flow is used to flush the rotating blades.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model uses a water pump to pump the standing sewage into the filter tank, and the sewage that enters washes the rotary blades, so that the rotary blades drive the rotating shaft to rotate, thereby rotating and stirring the activated carbon particles, so that the activated carbon particles fully filter the sewage, and the filtered sewage is then filtered through the filter plate and discharged from the outlet pipe. This design can intercept and precipitate the sewage and then fully filter and purify it, thereby improving the filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please combine Figure 1 - Figure 3 A construction sewage filter of this embodiment includes a sedimentation tank 1 and a filter tank 7. The filter tank 7 is connected to the sedimentation tank 1 through a water pump 8. An inlet 2 is opened at the top of the sedimentation tank 1, and an interception component is arranged inside the sedimentation tank 1 for intercepting large-particle concrete blocks and construction metal debris. A sedimentation part 6 is arranged at the bottom of the sedimentation tank 1 and below the interception component. A filtering mechanism is arranged inside the filter tank 7 for fully filtering the sewage after sedimentation, and a water outlet pipe 17 is connected to one side of the filter tank 7.

[0026] Please combine Figure 2 The filtering mechanism includes a filter box 9 fixedly installed inside the filter pool 7, a rotating shaft 10 is rotatably installed inside the filter box 9, and the inside of the filter box 9 is filled with activated carbon particles 12, and a rotating blade 11 is fixedly installed on the surface of the rotating shaft 10.

[0027] The water flow flushes the rotor blades 11, so that the rotor blades 11 drive the rotating shaft 10 to rotate, so that the rotor blades 11 stir the activated carbon particles 12, so that the activated carbon particles 12 can fully filter the sewage, thereby improving the filtering effect.

[0028] Please combine Figure 2 and Figure 3An eccentric disk 13 is fixedly connected to both ends of the rotating shaft 10, a through groove 14 corresponding to the eccentric disk 13 is opened at the bottom of the filter box 9, and a filter plate 15 sliding inside the filter tank 7 is arranged at the bottom of the filter box 9, and a second spring 16 is fixedly installed at the bottom of the filter plate 15, and the filter plate 15 is arranged corresponding to the eccentric disk 13, and the second spring 16 is fixedly installed on the inner wall of the filter tank 7.

[0029] The rotation of the rotating shaft 10 drives the eccentric disk 13 to rotate, so that the eccentric disk 13 squeezes the filter plate 15, and the filter plate 15 slides up and down by cooperating with the second spring 16 to prevent sand and gravel particles from clogging the filter plate 15. At the same time, the filter plate 15 is arranged at the bottom of the filter box 9. When the eccentric disk 13 is not in contact with the filter plate 15, the filter plate 15 blocks the through groove 14 to prevent the activated carbon particles 12 from leaking out.

[0030] Please combine Figure 2 The interception assembly includes a mounting plate 3 slidably connected to the top of the sedimentation tank 1 , and an interception net 4 is arranged inside the mounting plate 3 .

[0031] The interception net 4 intercepts larger concrete particles or iron sheets and wires to prevent such debris from affecting the normal use of the device.

[0032] Please combine Figure 2 The interception net 4 is detachably arranged, and the bottom of the mounting plate 3 is fixedly connected with a first spring 5 , which is fixedly mounted on the inner wall of the sedimentation tank 1 .

[0035] The implementation principle of a construction sewage filter in the embodiment of the present application is as follows: when working, a large amount of sewage enters the sedimentation tank 1 from the inlet 2, and is intercepted by the interception net 4. When the interception net 4 is intercepting, the first spring 5 is used for buffering to prevent heavier debris from damaging the interception net 4. The incoming sewage is first precipitated through the sedimentation part 6 to sink the sand and gravel particles to the bottom. The sewage after standing is pumped into the filter tank 7 through the water pump 8. The incoming sewage flushes the rotary blade 11, so that the rotary blade 11 drives the rotating shaft 10 to rotate, so that the rotary blade 11 stirs the activated carbon particles 12, so that the activated carbon particles 12 fully filter the sewage. The filtered sewage is then filtered by the filter plate 15 and discharged from the outlet pipe 17. The rotation of the rotating shaft 10 drives the eccentric disk 13 to rotate, so that the eccentric disk 13 squeezes the filter plate 15, and the filter plate 15 slides up and down through the cooperation with the second spring 16 to prevent the sand and gravel particles from clogging the filter plate 15.
