Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a filtering device for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage is divided into domestic sewage and industrial wastewater. The treatment of domestic sewage generally requires the salvage of floating objects and other debris first, and a screen machine is generally used to filter out debris on domestic sewage.

[0003] In the prior art entitled "A Filter Device for Sewage Treatment" with Publication (Announcement) No. CN219630784U and Publication (Announcement) Date 2023-09-05, it is proposed that "the sewage treatment tank and the intermediate water tank are connected by a filtration channel. At present, a multi-stage grid mesh is generally arranged in the filtration channel. The grid mesh can be used to filter debris. A grid machine can also be provided at the discharge port of the sewage treatment tank. The grid machine is used to salvage debris, and it is troublesome to collect the debris after filtration. To address this problem, the present application designs two sets of filter mesh transmission belts, which are used to filter debris, and then the inclined guide plates are used to guide the debris, effectively preventing the debris from being stuck at the bottom of the filter mesh transmission belt." The problem raised is solved.

[0004] However, in the above-mentioned prior art, when the debris is filtered and lifted, it will be accompanied by a lot of water. The debris and sewage are directly discharged through the inclined guide plate, and the sewage will also be directly discharged. At the same time, the wet debris falls on the guide plate and slides down by gravity, which is inefficient. Therefore, a new filtering device for sewage treatment is proposed to optimize the above-mentioned prior art. Utility Model Content

The baffle is used to shield the bottom gap between the filter mesh transmission belt and the filter channel to prevent impurities from flowing directly to the rear through the gap.

[0010] As a further solution of the utility model: a tensioning roller is provided on the inner side of the top of the mounting frame, and the tensioning roller is against the filter mesh transmission belt.

[0011] As a further solution of the utility model: guide grooves are provided at both ends of the mounting frame corresponding to the tensioning roller, and a first sliding seat and a second sliding seat are slidably connected inside the guide grooves.

[0015] 2. The utility model uses the second sliding seat to cooperate with the spring to squeeze the first sliding seat, so that the tensioning roller and the filter mesh transmission belt are placed on the filter mesh transmission belt, so that the filter mesh transmission belt is tensioned. At the same time, the position of the second sliding seat can be adjusted by rotating the threaded rod to control the tensioning force, effectively avoiding the problem that the filter mesh transmission belt is loose and the active roller and the driven roller cannot drive the filter mesh transmission belt to operate.

[0024] The active roller 4 is driven by the first motor 6, and the active roller 4 cooperates with the driven roller 5 to drive the filter mesh transmission belt 2 to run, so that the impurities filtered by the filter mesh transmission belt 2 are lifted to the collecting bucket 7, and the impurities entering the collecting bucket 7 fall into the discharge pipe 8, and the impurities are discharged under the action of the spiral auger 10 driven by the second motor 11, thereby achieving the effect of actively outputting the impurities. When the spiral auger 10 outputs the impurities, it squeezes the impurities through the gradually changing pitch, and cooperates with the filter mesh holes 9, thereby achieving the effect of draining water.

[0025] One side of the collecting bucket 7 is fixedly connected to the mounting frame 3 , and the other side of the collecting bucket 7 is symmetrically fixedly connected to a support plate, which is fixedly connected to the inner wall of the filtering channel 1 .

[0026] A baffle 12 that fits and matches the filter mesh transmission belt 2 is provided on the outer bottom side thereof, and the baffle 12 is fixedly connected to the inner wall of the filter channel 1. The baffle 12 shields the bottom gap between the filter mesh transmission belt 2 and the filter channel 1 to prevent impurities from flowing directly through the gap to the rear.

[0027] A tensioning roller 13 is provided on the inner side of the top of the mounting frame 3 , and the tensioning roller 13 abuts against the filter mesh transmission belt 2 .

[0028] Guide grooves 14 are provided on the mounting frame 3 at both ends corresponding to the tensioning roller 13, and a first sliding seat 15 and a second sliding seat 16 are slidably connected to the inner side of the guide groove 14. The tensioning roller 13 is rotatably connected between the two first sliding seats 15, and a plurality of springs 17 are fixedly connected between the first sliding seat 15 and the second sliding seat 16. The springs 17 provide elastic force to cause the first sliding seat 15 to drive the tensioning roller 13 to approach the filter mesh transmission belt 2 to provide elastic contact.

[0031] The working principle of the utility model is:

[0032] When in use, the first motor 6 runs, thereby driving the active roller 4 to rotate, and drives the filter mesh transmission belt 2 to run with the cooperation of the driven roller 5. At this time, the sewage passes through the filter channel 1, and the sewage passes through the filter mesh transmission belt 2 under the action of the baffle 12, wherein the impurities are filtered and lifted along with the operation of the filter mesh transmission belt 2, and the lifted impurities eventually rise to the top of the filter mesh transmission belt 2 and fall into the collecting bucket 7. The impurities entering the collecting bucket 7 fall into the discharge pipe 8, and at this time, the water is drained through the filter mesh holes 9. The second motor 11 drives the spiral auger 10 to rotate, thereby outputting the impurities in the discharge pipe 8 to the outside. During the output process, the impurities are squeezed, so that the water flows back along the inclined discharge pipe 8 and flows back into the filter channel 1 through the filter mesh holes 9.

[0033] When in use, the second sliding seat 16 squeezes the first sliding seat 15 through the spring 17. At this time, the first sliding seat 15 drives the tensioning roller 13 to press against the filter mesh transmission belt 2, so that the filter mesh transmission belt 2 is tensioned, which is convenient for the active roller 4 and the driven roller 5 to drive the filter mesh transmission belt 2 to run. When the filter mesh transmission belt 2 is loose, the threaded rod 18 can be rotated. At this time, the threaded rod 18 drives the second sliding seat 16 to slide in the guide groove 14, so that the tensioning roller 13 is further close to the filter mesh transmission belt 2, which has the effect of tensioning and adjusting.
