Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment equipment, and more particularly to a building sewage treatment device. Background Art

[0002] Many construction sites, such as those in development zones, factory areas, and road and bridge construction, are on newly developed land, often in the wilderness. Water supply, power supply, sewage treatment, accommodation, etc. are all inconvenient. On these construction sites, workers' food, clothing, housing, and transportation need to be solved within the site. The main sources of the wastewater generated are cleaning engineering vehicles, canteens, concrete pouring, etc. Since the site conditions cannot meet the requirements for sewage diversion, the wastewater generated by these activities is usually stored, treated, and then discharged after being mixed together.

[0003] During the storage and treatment process, since there are some waste materials such as building materials dust, particles, and oil stains in this sewage, filtration treatment is usually required. However, simple filtration is not convenient for filtering out the oil stains mixed in the dust. Especially for some large particles such as concrete, soil, and stones, which have many gaps and holes and are easy to store oil stains. During the storage process after separating these particles from the sewage, they will still rot, breed bacteria and mosquitoes, and produce odors, making it even more difficult to handle.

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a building sewage treatment device, including a treatment tank 1, a separation layer 2, a crushing structure 3 and a circulation structure 4. A power part 5 is provided on the side of the treatment tank 1. The power part 5 is used to drive the crushing structure 3 to operate. The separation layer 2 is arranged inside the treatment tank 1 and above the crushing structure 3. One end of the circulation structure 4 is arranged at the bottom of the treatment tank 1, and the other end is arranged above the separation layer 2.

[0020] In this embodiment, the separation layer 2 includes multiple layers of separation plates 21 and connecting plates 22 connected to both sides of the separation plates 21. An elastic airbag 23 is provided on the lowermost separation plate 21. The elastic airbag 23 is communicated with the separation plate 21 and the connecting plate 22. The separation plates 21 are arranged as required, but at least two layers are provided to facilitate the full mixing of sewage and bubbles.

[0021] In this embodiment, the crushing structure 3 includes a crushing knife 31 and a pressing plate 32. The crushing knife 31 and the pressing plate 32 are both installed on a clamping plate 33, and the clamping plate 33 is fixedly installed on a stepped shaft 34. The crushing knife 31 is used to crush large-particle sundries, and the pressing plate 32 cooperates with the elastic airbag 23 to extrude a large amount of gas in a short time.

[0022] In this embodiment, the circulating structure 4 includes a top suction hood 41 and a bottom suction hood 42. The top suction hood 41 and the bottom suction hood 42 are both arranged in a collection box 43 to recycle the sewage and sundries that fall into the collection box 43 back to the separation layer 2 to help the bubbles mix fully with the oil stains and powders.

[0023] In this embodiment, the treatment tank 1 includes a feeding port 11, a guiding plate 12, and an outer box housing 13. The feeding port 11 is arranged at the top of the outer box housing 13, and the guiding plate 12 is arranged below the feeding port 11. The feeding port 11 is used to feed sewage, and the guiding plate 12 is used to guide the flow of sewage.

[0024] In this embodiment, the separation plate 21 is inclinedly arranged in the treatment tank 1, and multiple groups of separation plates 21 are arranged end to end in a staggered manner to increase the travel distance of the sewage on the separation plate 21 as much as possible, thereby increasing the mixing time.

[0025] In this embodiment, the separation plate 21 includes a base body and a mesh surface. A cavity is provided inside the base body, the mesh surface covers the cavity of the base body, micropores are provided on the mesh surface, the cavity is communicated with a connecting plate 22, a pipeline 221 is provided inside the connecting plate 22, the lower part of the pipeline 221 is connected to an elastic airbag 23, an air pipe 231 communicating with the outside is provided on the side of the elastic airbag 23, and the air pipe 231 is connected to an external air pump. By blowing air into the elastic airbag 23 through the air pipe 231, the air will pass through the pipeline 221 and finally enter the cavity, and then be discharged from the micropores on the mesh surface to form tiny bubbles, which are mixed with the sewage flowing through the mesh surface. By increasing the surface area, the dust and oil stains in the sewage are adsorbed by the surface tension of the bubbles and mixed to form foam, realizing the separation of the dust and oil stains from the sewage.

[0026] In this embodiment, both ends of the stepped shaft 34 are rotatably installed on the treatment tank 1. The crushing knife 31 and the pressing plate 32 are arranged at intervals from each other. The end of the pressing plate 32 is provided with a forward-bending arc. During rotation, the pressing plate 32 contacts and presses the elastic airbag 23 through this arc, causing a large amount of gas in the elastic airbag 23 to suddenly rush out. This can not only push out the water flowing into the cavity through the micropores on the mesh surface, but also prevent the dust and oil stains in the sewage from blocking the micropores.

[0027] In this embodiment, screen meshes 35 are provided on both sides below the crushing structure 3, and the screen meshes 35 semi-surround the outside of the crushing structure 3. The top of the screen meshes 35 is fixedly installed in the treatment tank 1. A discharge hole is provided at the bottom of the screen meshes 35, and the discharge hole is located directly above the collection tank 43. The screen meshes 35 can filter out large particles in the sewage, and the crushing knife 31 crushes these large particles to release the dust and oil adsorbed therein.

[0028] In this embodiment, the top suction hood 41 is installed at the top of the side wall of the collection tank 43, and the outside of the top suction hood 41 is connected to the outside through a pipeline. Since the foam in the sewage falling into the collection tank 43 will float on the sewage, the top suction hood 41 provided at the upper end of the collection tank can suck out the foam on the upper layer of the sewage under the action of an external suction device, realizing the separation of powder, oil and sewage. At the same time, because it exists in the form of foam, it is also convenient for subsequent evaporation of water, leaving solid powder and oil, which is more convenient for separate treatment.

[0029] In this embodiment, the bottom suction hood 42 has an opening facing downward and is provided at the bottom of the collection tank 43. The bottom suction hood 42 is connected to the top of the treatment tank 1 through a pipeline and sprays the sucked material onto the separation layer 2 through the pipeline. The sewage mixed with large particles and dust not combined with bubbles will accumulate at the bottom layer of the collection tank 43 and is sucked from the bottom layer through the bottom suction hood 42, and these sewage are recycled back to the separation layer 2, repeating the above process until all the large particles are crushed to form powder that is more convenient to process.

[0030] Working principle: First, sewage is fed into the feeding port 11. The sewage flowing through the mesh surface of the separation plate 21 will be mixed with the tiny bubbles discharged through the micropores on the mesh surface. By increasing the surface area, the dust and oil in the sewage are adsorbed by the surface tension of the bubbles and mixed to form foam, and together with the remaining sewage and large particles, they flow into the crushing structure 3. The screen meshes 35 can filter out large particles in the sewage, and the crushing knife 31 crushes these large particles, and then they fall into the collection tank 43. The sewage mixed with large particles and dust not combined with bubbles will accumulate at the bottom layer of the collection tank 43 and is sucked from the bottom layer through the bottom suction hood 42, and these sewage are recycled back to the separation layer 2, repeating the above process until all the large particles are crushed to form powder that is more convenient to process. The foam in the sewage falling into the collection tank 43 will float on the sewage, and the top suction hood 41 provided at the upper end of the collection tank can suck out the foam on the upper layer of the sewage under the action of an external suction device, realizing the separation of powder, oil and sewage.

[0031] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all respects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
