Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment, specifically a building wastewater treatment device. Background Technology

[0002] Many construction sites, such as development zones, factory areas, and road and bridge construction sites, are newly developed land, often located in remote areas where water, electricity, sewage treatment, food, and accommodation are inconvenient. On these construction sites, workers need to solve all their needs for food, clothing, housing, and transportation on-site. The main sources of wastewater are washing construction vehicles, canteens, and concrete pouring. Because the conditions on the construction site cannot meet the requirements for sewage separation, the wastewater generated by these activities is usually mixed together for storage, treatment, and then discharged.

[0003] During storage and treatment, these wastewaters contain building material dust, particles, oil stains, and other waste materials, which usually require filtration. However, simple filtration is not convenient for removing oil stains mixed in with the dust, especially large particles of concrete, soil, and stones, which have many gaps and pores and are prone to storing oil stains. Even after these particles are separated from the wastewater and stored, they will still decompose, breed bacteria and insects, and produce odors, making them even more difficult to handle. Summary of the Invention

[0004] The purpose of this invention is to provide a building wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building wastewater treatment device, comprising a treatment tank, a separation layer, a pulverizing structure, and a circulation structure. The side of the treatment tank is provided with a power unit, which is used to drive the pulverizing structure to operate. The separation layer is disposed inside the treatment tank and located above the pulverizing structure. One end of the circulation structure is disposed at the bottom of the treatment tank, and the other end is disposed above the separation layer.

[0006] The separation layer includes multiple separation plates and connecting plates on both sides of the separation plates. The bottommost separation plate is provided with an elastic airbag, which is connected to the separation plates and the connecting plates.

[0007] The crushing structure includes a crushing blade and a pressing plate, both of which are mounted on a clamping plate, which is fixedly mounted on a stepped shaft.

[0008] The circulation structure includes a top suction hood and a bottom suction hood, both of which are located inside the collection box.

[0009] Preferably, the processing box includes a feeding port, a guide plate, and an outer casing. The feeding port is located at the top of the outer casing, and the guide plate is located below the feeding port.

[0010] Preferably, the separation plates are arranged at an angle inside the processing box, and multiple sets of separation plates are arranged alternately end to end.

[0011] Preferably, the separation plate includes a substrate and a mesh surface. The substrate has a cavity inside, the mesh surface covers the cavity of the substrate, the mesh surface has micropores, and the cavity communicates with a connecting plate.

[0012] Preferably, the connecting plate is provided with a pipe, and the lower part of the pipe is connected to the elastic airbag.

[0013] Preferably, the side of the elastic airbag is provided with an air tube that connects to the outside.

[0014] Preferably, both ends of the stepped shaft are rotatably mounted on the processing box, the crushing blade and the pressing plate are spaced apart from each other, and the end of the pressing plate has a forward-curved arc.

[0015] Preferably, the crushing structure has screens on both sides below it, and the screens partially surround the outside of the crushing structure. The top of the screens is fixedly installed inside the processing box, and the bottom of the screens has a discharge hole located directly above the collection box.

[0016] Preferably, the top suction hood is installed on the top of the side wall of the collection box, and the outside of the top suction hood is connected to the outside through a pipe.

[0017] Preferably, the bottom suction hood has an opening facing downwards and is located at the bottom of the collection box. The bottom suction hood is connected to the top of the processing box through a pipe and sprays the suction material onto the separation layer through the pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention uses a separation layer to inject microbubbles into the wastewater through micropores on the mesh surface as the wastewater passes through the separation plate. The microbubbles mix with oil and dust to form foam, thus cleaning the oil from the wastewater.

[0020] 2. The crushing structure of this invention can crush large particles in sewage. After the large particles are crushed, it is easier to discharge the oil that fills the gaps and holes in the particles, thus achieving a thorough cleaning effect.

[0021] 3. The circulating structure of this invention can continuously re-mix the sewage in the collection tank with air bubbles and agitate it, ensuring that the oil in the sewage is cleaned up as much as possible. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 6 The present invention provides a technical solution: a building wastewater treatment device, including a treatment tank 1, a separation layer 2, a crushing structure 3 and a circulation structure 4. The side of the treatment tank 1 is provided with a power part 5, which is used to drive the crushing structure 3 to operate. The separation layer 2 is disposed inside the treatment tank 1 and located above the crushing structure 3. One end of the circulation structure 4 is disposed at the bottom of the treatment tank 1 and the other end is disposed above the separation layer 2.

[0035] In this embodiment, the separation layer 2 includes multiple separation plates 21 and connecting plates 22 connected to both sides of the separation plates 21. The bottom separation plate 21 is provided with an elastic airbag 23. The elastic airbag 23 is connected to the separation plate 21 and the connecting plate 22. The separation plates 21 are set as needed, but at least two layers are set to facilitate the thorough mixing of sewage and air bubbles.

[0036] In this embodiment, the crushing structure 3 includes a crushing blade 31 and a pressing plate 32. Both the crushing blade 31 and the pressing plate 32 are mounted on a clamping plate 33. The clamping plate 33 is fixedly mounted on a stepped shaft 34. The crushing blade 31 is used to crush large particles of debris. The pressing plate 32 cooperates with the elastic airbag 23 to squeeze out a large amount of gas in a short time.

[0037] In this embodiment, the circulation structure 4 includes a top suction hood 41 and a bottom suction hood 42. Both the top suction hood 41 and the bottom suction hood 42 are installed inside the collection box 43, which recirculates the sewage and debris that fall into the collection box 43 back to the separation layer 2, helping the bubbles to mix fully with the oil and powder.

[0038] In this embodiment, the treatment box 1 includes a feeding port 11, a guide plate 12, and an outer casing 13. The feeding port 11 is located on the top of the outer casing 13, and the guide plate 12 is located below the feeding port 11. The feeding port 11 is used to feed sewage, and the guide plate 12 is used to guide the flow of sewage.

[0039] In this embodiment, the separation plate 21 is inclined inside the treatment tank 1, and multiple sets of separation plates 21 are arranged in an alternating manner to maximize the travel of sewage on the separation plate 21, thereby increasing the mixing time.

[0040] In this embodiment, the separation plate 21 includes a substrate and a mesh surface. The substrate has a cavity inside, and the mesh surface covers the cavity of the substrate. The mesh surface has micropores. The cavity is connected to a connecting plate 22. The connecting plate 22 has a pipe 221 inside, and the lower part of the pipe 221 is connected to an elastic airbag 23. The side of the elastic airbag 23 has an air pipe 231 connected to the outside. The air pipe 231 is connected to an external air pump. Air is blown into the elastic airbag 23 through the air pipe 231. The air passes through the pipe 221 and eventually enters the cavity. It is then discharged through the micropores on the mesh surface to form microbubbles. These microbubbles mix with the sewage flowing through the mesh surface. By increasing the surface area, the surface tension of the bubbles adsorbs the dust and oil in the sewage and mixes them to form foam, thus separating the dust and oil from the sewage.

[0041] In this embodiment, both ends of the stepped shaft 34 are rotatably mounted on the processing box 1. The crushing blade 31 and the pressing plate 32 are spaced apart from each other. The end of the pressing plate 32 is provided with a forward-curved arc. When the pressing plate 32 rotates, it contacts the elastic airbag 23 through this arc and presses the elastic airbag 23, causing a large amount of gas in the elastic airbag 23 to suddenly rush out. This can push out the water that flows into the cavity through the micropores of the mesh surface, and also prevent dust and oil in the sewage from clogging the micropores.

[0042] In this embodiment, screens 35 are provided on both sides below the crushing structure 3 and the screens 35 partially surround the outside of the crushing structure 3. The top of the screens 35 is fixedly installed in the processing box 1, and the bottom of the screens 35 is provided with a discharge hole. The discharge hole is located directly above the collection box 43. The screens 35 can filter out large particles in the sewage and crush these large particles by the crushing blades 31, releasing the dust and oil adsorbed therein.

[0043] In this embodiment, the top suction hood 41 is installed on the top side wall of the collection tank 43. The outer side of the top suction hood 41 is connected to the outside through a pipe. Since the foam in the sewage falling into the collection tank 43 will float on the sewage, the top suction hood 41 set at the top of the collection tank can be used to suck out the foam on the top of the sewage under the action of the external suction equipment, so as to separate the powder, oil and sewage. At the same time, since it exists in the form of foam, it is also convenient for subsequent evaporation of water, leaving solid powder and oil, which is easier to separate and process.

[0044] In this embodiment, the bottom suction hood 42 has an opening facing downwards and is located at the bottom of the collection box 43. The bottom suction hood 42 is connected to the top of the processing box 1 through a pipe and sprays the suction material onto the separation layer 2 through the pipe. Wastewater mixed with large particles and dust that has not been combined with air bubbles will accumulate at the bottom of the collection box 43. The wastewater is then sucked from the bottom by the bottom suction hood 42 and recycled back to the separation layer 2. The above process is repeated until all the large particles are crushed into powder that is easier to process.

[0045] Working principle: First, wastewater is fed into the feed port 11. The wastewater flowing through the mesh of the separation plate 21 mixes with the micropores on the mesh to form tiny bubbles. By increasing the surface area, the surface tension of the bubbles adsorbs the dust and oil in the wastewater and mixes them to form foam. Along with the remaining wastewater and large particles, the foam flows into the crushing structure 3. The screen 35 filters out the large particles in the wastewater and crushes them with the crushing blade 31. The foam then falls into the collection box 43. The wastewater mixed with large particles and dust that has not been combined with the bubbles will accumulate at the bottom of the collection box 43. The bottom suction hood 42 will suck the wastewater from the bottom and recycle it back to the separation layer 2. This process is repeated until all the large particles are crushed into powder that is easier to process. The foam in the wastewater falling into the collection box 43 will float on the wastewater. The top suction hood 41 set at the top of the collection box can suck out the foam on the top of the wastewater with the help of external suction equipment, thus separating the powder, oil and wastewater.

[0046] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
