Description

Technical Field

[0001] The present invention relates to the field of sewage and wastewater treatment and discharge devices, and specifically to wastewater treatment and discharge devices. Background Art

[0002] The discharge of wastewater and sewage has strict requirements in the industrial environment. However, for drainage equipment in living areas, it is very difficult to separately discharge sewage, wastewater, and rainwater. When the mixed discharge flows into rivers, it will pollute the rivers. Moreover, outdoor kitchen waste will also be dumped into the sewer pipes, causing pollution of rainwater and blockage of the sewer pipes. When encountering heavy rain, the occurrence of urban waterlogging is not due to the drainage speed of the sewer pipes. More often, when discharging heavy rainwater, various garbage will be carried and blocked in the pipes, resulting in the inability to normally discharge the heavy rainwater during heavy rain weather and forming urban waterlogging. Therefore, to solve the above problems, it is first necessary to clean the garbage that is prone to generating wastewater and sewage and causing blockages. Therefore, every time there is urban waterlogging, workers need to manually clean it, which not only causes a long time of waterlogging but also a high labor cost.

[0003] For this reason, technicians in this field have designed a wastewater treatment and discharge device to solve the above problems. Summary of the Invention

[0004] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a wastewater treatment and discharge device that can be adapted to the welding of mesh sheets with different spacings.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: It includes a first drain pipe. At the inner bottom of the first drain pipe, a water collection plate is fixedly connected. Inside the first drain pipe, a rainwater collection mechanism is installed. The rainwater collection mechanism includes a connecting rod that is slidably connected to the first drain pipe. At the bottom of the connecting rod, a water collection airbag is connected. At the top of the connecting rod, a circular plate is connected. On both sides of the first drain pipe, sewage pipes are provided. On one side of the sewage pipe, a side pipe that is connected to the first drain pipe and communicates with it is connected. At the bottom of the first drain pipe, a second drain pipe is connected. On both sides of the second drain pipe, grease pipes are connected. The center of the water collection plate is slidably connected to the water collection airbag through an opening.

[0006] Preferably, a grease mesh is slidably connected inside the grease pipe, and the diameters of the grease pipe and the grease mesh are larger than that of the second drain pipe. The axis of the sewage pipe is tangent to the outer circle of the grease mesh.

[0007] Preferably, an annular mesh is slidably connected to the inner top of the first drain pipe. The diameter of the annular mesh is larger than that of the circular plate. The annular mesh is always located above the circular plate. The annular mesh can be in contact with the bottom surface of the discharge cylinder through sliding. The annular mesh is in contact with and slidably connected to the side pipe.

[0008] Preferably, the circular plate can rotate in a folding manner on both the left and right sides, and water seepage openings are provided on the surface of the circular plate. The upper surface of the circular plate is distributed in a structure with a higher center and lower periphery, and the circular plate can be inserted into the inside of the discharge cylinder.

[0009] Preferably, two bottom plates are rotatably connected to the bottom of the discharge cylinder through openings. The rotational connection between the bottom plates and the discharge cylinder is located at the edge of the opening at the bottom of the discharge cylinder. The bottom plates can rotate outward in an unfolded manner along the rotation axis. There is a slit between the two bottom plates, and the width of the slit is greater than twice the thickness of the circular plate. The slit is in a straight line and is parallel to the folding line of the circular plate. The two bottom plates are combined into a structure with a higher center and lower periphery.

[0010] Preferably, a sewage discharging member is further provided in the sewage pipe. The sewage discharging member includes a cover plate, a rope, and a supporting plate. The cover plate is located at the top of the sewage pipe. The bottom of the cover plate is connected to the supporting plate through a rope. The supporting plate is located in the middle of the sewage pipe, and the height of the supporting plate is lower than the height of the side pipe. The sewage pipe is communicated with the grease pipe.

[0011] Preferably, the water collecting airbag is in a conical structure, and the volume of the water collecting airbag above the water collecting plate is larger than the part of the water collecting airbag below the water collecting plate.

[0012] The beneficial effects of the present invention: In the state of heavy rain, all rainwater will gather into the sewer, along with various garbage. This device first collects the rainwater, and then uses the buoyancy generated by the rainwater on the water collecting airbag to push the garbage that has gathered at the inlet upward, discharging the blocked garbage, helping the heavy rainwater to drain quickly, and avoiding the problem of blockage of the sewer pipe; In the period lacking rainwater, even if there is garbage gathered at the inlet, the grease will drain to both sides, reducing the subsequent mixing of rainwater, sewage, or wastewater, and also avoiding the situation of grease condensation and blockage in the sewer pipe. Since the sewage pipe and the grease pipe are interconnected, after cleaning the sewage or wastewater in the sewage pipe, it can also be directly inserted into the grease pipe in the form of a long rod to push the rotation of the grease net to break the root of the caked grease, making it easier to be washed away, greatly reducing the problem of blockage of the main drainage pipe, and also reducing the mixing of rainwater and sewage or wastewater, further enhancing the protection of the ecological river environment.

[0026] The present invention provides a wastewater treatment and discharge device, as Figure 1-7 shown, which includes a first drain pipe 1. A water collecting plate 102 is fixedly connected to the inner bottom of the first drain pipe 1. A rainwater collection mechanism 6 is installed inside the first drain pipe 1. The rainwater collection mechanism 6 includes a connecting rod 601 that is slidably connected to the first drain pipe 1. The bottom of the connecting rod 601 is connected to a water collecting airbag 603, and the top of the connecting rod 601 is connected to a circular plate 602. Sewage pipes 5 are arranged on both sides of the first drain pipe 1. One side of the sewage pipe 5 is connected to a side pipe 501 that is communicated with the first drain pipe 1. The bottom of the first drain pipe 1 is connected to a second drain pipe 4. Grease pipes 7 are connected to both sides of the second drain pipe 4. The center of the water collecting plate 102 is slidably connected to the water collecting airbag 603 through an opening.

[0027] A grease screen 701 is slidably connected inside the grease pipe 7, and the diameters of the grease pipe 7 and the grease screen 701 are larger than those of the second drain pipe 4. The grease pipe 7 is thicker than the second drain pipe 4. For the grease that is likely to be stationary for a long time in winter, the grease pipe 7 is more likely to accumulate grease, but it does not affect the water passing through the center of the grease pipe 7. Blockage only occurs when the grease blocks up to the axial position of the grease pipe 7. The axis of the sewage pipe 5 is tangent to the outer circle of the grease screen 701. The sewage pipe 5 can reach the grease pipe 7 directly. Workers can use a long rod to push the rotation of the grease screen 701, which can play a role in destroying the root of large grease blocks. The grease screen 701 adopts a mesh structure, which can facilitate the grease to pass through the grease screen 701 and adhere to the grease pipe 7. When the grease screen 701 is rotated, the root of the grease block can be easily destroyed, which is convenient for cleaning.

[0028] A ring network 101 is slidably connected to the top inner circle of the first drain pipe 1. The diameter of the ring network 101 is larger than the diameter of the circular plate 602. The ring network 101 cannot be pushed by the disc. Instead, when there is a lot of sewage and garbage, the garbage forms a lump and gets stuck with the ring network 101 at the edge. When the circular plate 602 pushes the garbage upward, the garbage will move upward together with the ring network 101, preventing the garbage from overflowing at the outlet of the first drain pipe 1. The ring network 101 is always located above the circular plate 602. The ring network 101 can come into contact with the bottom surface of the discharge cylinder 3 through sliding. The ring network 101 cannot enter the discharge cylinder 3. The ring network 101 is in contact with and slidably connected to the side pipe 501. The ring network 101 can not only fix the garbage, but also allow the oil stains after flushing the kitchen waste to slowly overflow into the sewage pipes 5 on both sides, realizing the separation of sewage and rainwater. The circular plate 602 can rotate in a folded manner on the left and right sides. There are water seepage openings on the surface of the circular plate 602. The upper surface of the circular plate 602 is distributed in a structure with a higher center and lower periphery. The circular plate 602 can be inserted into the interior of the discharge cylinder 3. The circular plate 602 can push the garbage into the discharge cylinder 3. When the circular plate 602 descends and disengages from the interior of the discharge cylinder 3, the circular plate 602 can leave the garbage in the discharge cylinder 3 by folding inward, and itself can fold and disengage from the interior of the discharge cylinder 3 and return to the first drain pipe 1. Two bottom plates 301 are rotatably connected to the bottom of the discharge cylinder 3 through openings. The rotational connection between the bottom plates 301 and the discharge cylinder 3 is located at the edge of the opening at the bottom of the discharge cylinder 3. The bottom plates 301 can rotate outward in an unfolded manner along the axis. There is a slit between the two bottom plates 301, and the width of the slit is greater than twice the thickness of the circular plate 602. The slit is in a straight line and parallel to the folding line of the circular plate 602. Under the push of the circular plate 602, the bottom plates 301 can rotate upward to open. When the circular plate 602 needs to move downward after entering the interior of the discharge cylinder 3, the bottom plates 301 cannot open downward. The circular plate 602 can only pass through the slit of the bottom plates 301 by folding. The two bottom plates 301 are combined into a structure with a higher center and lower periphery. The distribution characteristic of the higher center and lower periphery of the bottom plates 301 can allow the oil to flow to both sides, preventing it from flowing back into the first drain pipe 1. A sewage discharge member 502 is also provided in the sewage pipe 5. The sewage discharge member 502 includes a cover plate 5021, a rope 5022, and a support plate 5023. The cover plate 5021 is located at the top of the sewage pipe 5. The bottom of the cover plate 5021 is connected to the support plate 5023 through the rope 5022. The support plate 5023 is located in the middle of the sewage pipe 5. The height of the support plate 5023 is lower than the height of the side pipe 501. The sewage pipe 5 is connected to the grease pipe 7. The sewage discharge member 502 can facilitate the cleaning personnel to take it out for cleaning at any time. The bottom support plate 5023 can hold the grease, preventing the oil stains from flowing into the main sewage discharge pipeline. The water collecting airbag 603 is in a conical structure. The volume of the water collecting airbag 603 above the water collecting plate 102 is larger than the part of the water collecting airbag 603 below the water collecting plate 102. The conical structure of the water collecting airbag 603 is more convenient for repeated docking with the holes on the water collecting plate 102, which can avoid the problem of being unable to block the holes. Secondly, the water collecting plate 102 and the water collecting airbag 603 together form a water collecting structure. After storing a certain amount of rainwater, the buoyancy brought by the rainwater to the water collecting airbag 603 can be used to clean the garbage above, effectively avoiding the situation that the sewage pollutes the rainwater due to garbage blockage. Taking the ring plate 2 as the demarcation line, all the structures below the ring plate 2 are underground structures, while all the structures above the ring plate 2 are above-ground structures. When installing, the discharge cylinder 3 must be located above the drain pipe 1, and the height of the discharge cylinder 3 must be higher than that of the drain pipe 1; During use, a lot of garbage or impurities will enter above the circular plate 602. Especially during heavy rain, garbage floating objects will enter above the circular plate 602, and a large amount of rainwater will seep downward along the holes on the surface of the circular plate 602 and gradually accumulate above the water collecting plate 102 and the water collecting airbag 603. The buoyancy of the water collecting airbag 603 in a large amount of rainwater will rise, but the pressure of the rainwater will also press on the water collecting airbag 603. When the critical value is reached, the water collecting airbag 603 will drive the circular plate 602 to move upward, pushing a large amount of garbage into the interior of the discharge cylinder 3; The process of the circular plate 602 pushing the garbage is as follows: When there is a lot of garbage, the garbage will be stuck with the ring net 101. When the circular plate 602 moves upward, it will drive the ring net 101 to move upward together, but the ring net 101 cannot enter the discharge cylinder 3, while the circular plate 602 can enter the interior of the discharge cylinder 3. The ring net 101 protects the garbage and prevents the garbage from overflowing to both sides. The discharge cylinder 3 and the garbage will push the bottom plate 301 to open to both sides to let the garbage enter. When the water level in the drain pipe 1 drops, the water collecting airbag 603 will move downward again to continue the water storage operation. When the circular plate 602 wants to actively pass through the already closed bottom plate 301, since the bottom plate 301 cannot rotate downward to open, the circular plate 602 will fold inward to retain most of the garbage in the discharge cylinder 3. The circular plate 602 passes through the gap between the two bottom plates 301 by folding and unfolds again in the discharge cylinder 3 to continue receiving garbage; When the circular plate 602 is inside the discharge cylinder 3, the kitchen waste in the garbage will continuously overflow oily liquids outward. Due to the slow outward overflow characteristics of these liquids, the oil stains will gradually flow to both sides and flow into the sewage pipe 5, and are received by the bottom support plate 5023. When cleaning is required, directly take out the entire sewage discharge part 502 to pull out all the oil stains; Since it is impossible to completely avoid oil stains flowing into the sewer, long-term accumulation of oil stains will cause solidification and form oil blocks to block the sewage outlet. Therefore, an oil pipe 7 is provided, and its diameter is much larger than that of the drain pipe 4. The oil stains will accumulate in the oil pipe 7 with a larger diameter. The initial accumulation will not affect the flow of water. Once siltation occurs, the grease net 701 can be rotated by pushing it with a long rod through the sewage pipe 5, and the large oil blocks can be broken by rotation, allowing the water flow to wash them away naturally. It should be noted that the above specific implementation manners are only preferred embodiments of the present invention and the technical principles applied. Those skilled in the art should understand that various modifications, equivalent replacements, changes, etc. can also be made to the present invention. However, as long as these transformations do not deviate from the spirit of the present invention, they should be within the protection scope of the present invention. In addition, some terms used in the description and claims of this application are not restrictive, but are only for the convenience of description.
