Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a concrete sewage treatment device. Background Art

[0002] A large amount of sewage is often generated during the concrete production process. This sewage not only contains conventional building materials such as sand, gravel, cement, etc., but also contains various types of concrete additives. If it is discharged directly, it will cause serious pollution to the natural environment and greatly waste a large amount of sand, gravel and other building materials in the sewage. Treating sewage can not only recycle the sand and gravel in concrete sewage and realize the recycling of resources, but also purify sewage and save water resources. At the same time, it also improves the utilization rate of water resources and reduces production costs. Before sewage purification, large particles such as sand and gravel in sewage need to be filtered out.

[0003] Among them, the existing filtering method is to install a filter at the drainage end. Although this method can filter the sewage, it is necessary to stop the water supply when cleaning the sand and gravel on the filter, otherwise the sewage will get on the workers, and stopping the water supply will reduce the filtering efficiency.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A concrete sewage treatment equipment, such as Figure 1-Figure 3It includes a filtering device and a rectangular box 1, the upper and lower parts of the rectangular box are bell mouths facing each other, the rectangular box 1 is supported by a bracket 13, the top surface of the rectangular box 1 is connected to a water inlet pipe 2 through a corresponding bell mouth, and the bottom surface is connected to a water outlet pipe 3 through a corresponding bell mouth, and a first slide groove is horizontally opened on the front and rear inner walls of the rectangular box 1; the filtering device includes two fixedly connected filtering boxes 4, the filtering boxes 4 are parallel and penetrated from top to bottom, and the front and rear surfaces of the filtering boxes 4 are fixedly connected to a first slide rod 5 adapted to the first slide groove; the front and rear inner walls of the filtering boxes 4 are horizontally opened Two slide grooves, a second slide rod 6 is slidably matched in the second slide groove, the two second slide rods 6 are fixedly connected by a filter screen 16, and the longitudinal width of the filter screen 16 is the same as the spacing between the front and rear inner walls of the filter box 4, and the two filter boxes 4 are provided with a first strip groove 7 through which the filter screen 16 passes on the back side, and the inner wall of the top surface of the first strip groove 7 and the top surface of the filter screen 16 are located on the same horizontal plane, and outlet grooves through which the filter box 4 passes are opened on both sides of the rectangular box 1, the length of the filter box 4 is the same as the spacing between the two outlet grooves, and any filter box 4 is located in the rectangular box 1.

[0022] When the present application is in use, the concrete sewage enters the rectangular box 1 through the water inlet pipe 2 and flows into the corresponding filter box 4, and the filter screen 16 in the filter box 4 filters the concrete sewage, and the filtered water flows out through the outlet pipe 3. Among them, when the filter box 4 is used for a period of time, the filter box 4 that is not in the rectangular box 1 is pushed, so that the filter box 4 located in the rectangular box 1 is moved out through the corresponding outlet slot, and the new filter box 4 enters through the corresponding outlet slot. After the filter box 4 is moved out, the worker first manually selects and discards the useless concrete blocks or other wastes, and then pulls the filter screen 16, the filter screen 16 is pulled out from the strip groove, and the sand and gravel fall from the gap between the filter screen 16 and the filter box 4, thereby realizing the collection of sand and gravel. Among them, the selection of concrete blocks and the collection of sand and gravel are both carried out on one side of the rectangular box 1, and there is another filter box 4 in the rectangular box 1 for filtering, so the selection of concrete blocks and the collection of sand and gravel will not be touched by sewage to the workers, and will not affect their normal filtration, thereby improving the filtration efficiency.

[0023] In order to prevent sewage from flowing out from the gap between the outlet groove and the filter box 4, and between the filter screen 16 and the first strip groove 7, the side of the filter box 4 is consistent with the shape of the outlet groove and can block the outlet groove, and the side of the filter screen 16 is fixedly connected with a baffle 8 that can close the first strip groove 7. The baffle 8 blocks the first strip groove 7, and the side of the filter box 4 blocks the outlet groove, thereby preventing sewage from splashing out.

[0024] After filtering for a period of time, there will be certain stains on the filter 16, which will block the filter 16 opening and affect the reuse of the filter 16. This problem has not been solved. The front and rear inner walls of the filter box 4 are also laterally provided with a third slide groove 9, which is located below the second slide groove and parallel to the second slide groove. The opposite sides of the two filter boxes 4 are also provided with a second strip groove through which the filter 16 can pass. The second strip groove is blocked by a blocking plate, so that the filter 16 can be pulled out, rotated 180 degrees in the opposite direction, and then inserted into the second strip groove of the filter box 4 in the rectangular box 1 again, so that the filter 16 can be backwashed with sewage to prevent the filter 16 from being blocked by silt and unable to be used normally, while eliminating the waste of water resources caused by using clean water to clean the filter 16.

[0025] After the filter box 4 is pulled out, the filter screen 16 is loaded with sand, gravel, concrete and other residues, which makes the filter box 4 on this side heavier. At the same time, since there is no support after the filter box 4 is removed, the middle of the filter box 4 is easily bent by the gravity of the sand, gravel and other residues, which affects normal use. For this reason, the two sides of the rectangular box 1 are vertically connected with support rods 10, and there are two support rods 10 distributed along the longitudinal direction of the rectangular box 1. The opposite side of the support rods 10 is provided with a slideway into which the first slide bar 5 can slide, and a support beam 11 is fixedly connected between the support rod 10 and the rectangular box 1. The support rod 10 and the support beam 11 can support the removed filter box 4, wherein the support beam 11, the support rod 10 and the rectangular box 1 form a triangular support for better stability.

[0026] In order to better support the filter 16, a slot 14 is opened on the side of the filter box 4 away from the first strip groove 7. A block 15 matching the slot 14 is arranged in the slot 14. The block 15 is fixedly connected to the filter 16, so as to better support the filter 16 on that side.

[0027] The two sides of the rectangular box 1 are fixedly connected with a feed plate 12, and the feed plate 12 is inclined downward in the opposite direction of the rectangular box 1. The opposite surfaces of the two rectangular boxes 1 are fitted and fixedly connected, and the upper part of the fitting surface of the rectangular box 1 is an inclined surface inclined from top to bottom in the opposite direction. The feed plate 12 can play a better material guiding effect, and the inclined surface on the side of the filter box 4 can ensure that the sewage enters the corresponding filter box 4 better.

[0028] The use of the present application can be achieved by filtering with one filter box 4 located inside the rectangular box 1 and the other filter box 4 located outside, thereby facilitating the cleaning of residues on the filter screen 16 inside the filter box 4, which not only does not affect the normal filtration of concrete sewage, but also prevents sewage from splashing on workers during cleaning.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
