Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage treatment technology, and in particular to an integrated high-efficiency coagulation sedimentation and filtration device. Background Technology

[0002] Wastewater is water that has become contaminated with impurities and pollutants during production, daily life, and natural processes, losing its original usability. If discharged directly without treatment, its harmful components will damage the ecological environment and may also harm human health through the food chain. Therefore, it must be treated with basic processes such as sedimentation and coagulation to reduce pollution before being discharged.

[0003] In current wastewater treatment technologies, coagulation, sedimentation, and filtration equipment are often connected in one go via pipelines to ensure continuous wastewater purification operations and efficient, uninterrupted treatment processes. However, since the coagulation, sedimentation, and filtration equipment used in wastewater purification is mostly designed as separate units, the equipment needs to be connected through a large number of pipelines, which increases the overall footprint, reduces wastewater treatment efficiency, and makes daily operation procedures relatively cumbersome. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most coagulation, sedimentation and filtration equipment used in sewage purification in the prior art is designed as separate units, which require a large number of pipelines to connect the equipment, thus increasing the overall footprint. Therefore, this invention proposes an integrated and efficient coagulation, sedimentation and filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated high-efficiency coagulation sedimentation filtration device includes a main chamber, in which an inclined perforated plate and a sludge hopper are fixedly connected respectively. A main water inlet pipe is fixedly installed on the main chamber. A coagulation chamber is fixedly installed in the main chamber, and the main water inlet pipe and the coagulation chamber are connected. A water distribution pipe is fixedly installed on the coagulation chamber and extends to below the inclined perforated plate. The device also includes: A filter assembly is disposed in the main chamber and is used to filter the supernatant after passing through the perforated plate. A sludge suction assembly is located below the sludge hopper and is used to suction sludge from the sludge hopper. A stirring assembly is disposed inside the coagulation chamber and is used to stir the fluid inside the coagulation chamber.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5An integrated high-efficiency coagulation sedimentation filtration device includes a main chamber 1, within which a perforated plate 2 and a sludge hopper 3 are fixedly connected. The perforated plate 2 optimizes the water flow path in the sedimentation zone—slowing down the water flow velocity to provide sufficient settling time for suspended solids in the wastewater, while also preventing secondary re-floating of settled sludge due to water flow impact. Compared to traditional horizontal flow sedimentation structures, this design significantly improves the separation efficiency of the supernatant and reduces the amount of suspended solids carried into subsequent filtration stages, laying a solid foundation for the efficient operation of the filtration components. The sludge hopper 3 features a conical structure that is wider at the top and narrower at the bottom, utilizing gravity to guide the settled sludge to naturally converge at the bottom of the hopper, preventing sludge from forming dead corners at the bottom of the main chamber 1 and reducing the risk of contamination within the chamber due to sludge retention. Simultaneously, the sludge hopper 3 is located above the sludge extraction component and is connected to the connecting pipe, providing a centralized collection space for the sludge extraction component to accurately extract sludge, ensuring more thorough and efficient sludge extraction and reducing the impact of sludge residue on the device's treatment effect. A main water inlet pipe 4 is fixedly installed on the main chamber 1. A coagulation chamber 5 is fixedly installed inside the main chamber 1, and the main water inlet pipe 4 and the coagulation chamber 5 are connected. A water distribution pipe 6 is fixedly installed on the coagulation chamber 5, and the water distribution pipe 6 extends to the bottom of the inclined hole plate 2. It also includes: The filter assembly is located in the main chamber 1 and is used to filter the supernatant after passing through the inclined plate 2. The sludge suction component is located below the sludge hopper 3 and is used to remove sludge from the sludge hopper 3. A stirring assembly is installed inside the coagulation chamber 5 and is used to stir the fluid inside the coagulation chamber 5.

[0017] Reference Figure 2 , Figure 3 and Figure 5 The filtration components include: a drainage pipe 8, a filter tank 9, and a water collection tank 10.

[0018] The drainage pipe 8 is fixedly installed inside the main chamber 1, and is positioned directly above the perforated plate 2; the filter tank 9 is fixedly installed through the bottom of the drainage pipe 8; the water collection tank 10 is fixedly installed through the drainage pipe 8; the drainage pipe 8 collects the supernatant after sedimentation through the perforated plate 2, preventing the supernatant from mixing again with the unsedimented sludge below, thus ensuring stable water quality entering subsequent filtration stages. Its fixed installation method ensures the stability of the drainage path, preventing incomplete supernatant collection or impurity contamination due to pipe displacement.

[0019] The filter assembly also includes: a backwash outlet pipe 91, filter media 93, and a backwash inlet pipe 92.

[0020] A backwash outlet pipe 91 is embedded and fixedly installed in a through-type configuration on the filter tank 9, with one end extending to the outside of the main chamber 1. Filter media 93 is fixedly installed inside the filter tank 9. A backwash inlet pipe 92 is embedded and fixedly installed in a through-type configuration on the filter tank 9, with one end extending to the outside of the main chamber 1 and the other end extending below the filter media 93. As the core of the filtration process, the filter media 93's porous structure can deeply trap residual micro-suspended solids, colloidal particles, and other impurities in the supernatant, further improving the quality of the effluent. The fixed installation method prevents the filter media 93 from shifting or being lost under the impact of water flow, ensuring a stable and long-lasting filtration effect.

[0021] Reference Figures 2-3 The sludge pumping assembly includes: a sludge pump 7, a connecting pipe, a sludge discharge pipe 71, and a sludge return pipe 72.

[0022] The sludge pump 7 is fixedly installed at the bottom of the inner cavity of the main chamber 1; the connecting pipe is fixedly installed on the sludge pump 7 and is connected to the top of the sludge hopper 3; the sludge discharge pipe 71 is fixedly installed on the sludge pump 7, and one end of the sludge discharge pipe 71 extends to the outside of the main chamber 1; the sludge return pipe 72 is fixedly installed in a through-type manner on the sludge discharge pipe 71 and the main water inlet pipe 4. The sludge discharge pipe 71 can directly discharge the pumped sludge from the device, realizing the rapid removal of sludge; the sludge return pipe 72 forms a sludge return channel—when the sludge concentration is low, the sludge can be transported back to the main water inlet pipe 4 by controlling valve 1 73 and valve 2 74, and re-enter the coagulation chamber 5 to participate in the reaction, thereby improving the removal rate of pollutants in the sludge and avoiding resource waste.

[0023] The sludge suction assembly also includes: valve 1 73 and valve 2 74.

[0024] Valve 1 73 is fixedly installed on sludge discharge pipe 71; Valve 2 74 is fixedly installed on sludge return pipe 72.

[0025] Reference Figures 1-4 The mixing assembly includes: a cross rotor 51, a motor 52, a first fixed disc 53, a second fixed disc 54, and bolts 55.

[0026] The cross-shaped rotating rod 51 is rotatably connected to the inner wall of the main chamber 1 and is located inside the coagulation chamber 5. The motor 52 is fixedly connected to the outer wall of the main chamber 1 and drives the cross-shaped rotating rod 51 to rotate. The first fixed plate 53 is fixedly sleeved on the cross-shaped rotating rod 51. The second fixed plate 54 is horizontally slidably sleeved on the cross-shaped rotating rod 51. The same bolt 55 is threadedly connected to both the first fixed plate 53 and the second fixed plate 54, and a matching nut is threaded onto the bolt 55. The adjustable structure, which uses the same bolt 55 for threaded connection and locking with the nut, allows workers to loosen the bolt 55 to disassemble the main rod 56 and the agitator 57 for cleaning, preventing excessive residue from adhering to the agitator 57 and affecting the mixing effect.

[0027] The mixing assembly also includes: a main rod 56 and a mixing paddle 57.

[0028] The main rod 56 is horizontally slidably sleeved on the cross rotating rod 51, and the main rod 56 and the fixed disk 54 are fixedly connected; the stirring paddle 57 is fixedly connected to the outer wall of the main rod 56.

[0029] The main compartment 1 is equipped with a movable top cover 11 for protecting its interior.

[0030] The functional principle of this utility model can be explained through the following operation methods: When in use, first cover the top cover 11 of the main chamber 1 to protect the internal components, and the fluid to be treated enters the coagulation chamber 5 through the main water inlet pipe 4.

[0031] The motor 52 of the stirring assembly is started, which drives the cross rotor 51 inside the coagulation chamber 5 to rotate. On the cross rotor 51, the first fixed disk 53 and the second fixed disk 54, which are fixed by bolts 55 and nuts, rotate synchronously, driving the main rod 56 connected to the second fixed disk 54 and the outer stirring paddle 57 to rotate, so as to fully stir the fluid in the chamber to achieve coagulation reaction.

[0032] After coagulation, the fluid is transported to the area below the inclined orifice plate 2 via the water distribution pipe 6 on the coagulation chamber 5. As it flows upward along the inclined orifice plate 2, the suspended solids settle to the mud hopper 3 below, while the supernatant flows to the area directly above the inclined orifice plate 2 and enters the filter tank 9 through the diversion pipe 8. After being filtered by the filter media 93 in the filter tank 9, the qualified water is discharged through the backwash inlet pipe 92.

[0033] When the filter tank 9 needs to be cleaned, flushing water is introduced through the backwash inlet pipe 92. After passing through the filter media 93, the flushing water is discharged from the backwash outlet pipe 91 that extends to the outside of the main chamber 1, thus completing the backwashing.

[0034] The sludge in sludge hopper 3 is handled by the sludge pumping assembly: start sludge pump 7, the sludge is pumped out through the pipe, open valve 1 73 to discharge through sludge discharge pipe 71, open valve 2 74 to return to the main water inlet pipe 4 for further treatment through sludge return pipe 72.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
