Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a high-efficiency sludge removal integrated water purifier. Background Technology

[0002] Traditional integrated water purification systems generally employ a combined design of processes such as coagulation, sedimentation, filtration, and sludge removal. However, significant shortcomings remain in the sludge removal stage. For example, conventional systems rely on gravity sedimentation and timed manual sludge removal, resulting in low sludge removal efficiency, long cycles, and poor sludge concentration, which can easily lead to filter media clogging or fluctuations in effluent turbidity. While some systems incorporate automatic sludge removal systems (such as siphon backflushing or sludge removal valves), they still require external water pumps or air compressors, resulting in high energy consumption. Furthermore, sludge removal necessitates system shutdown, affecting continuous operation. In addition, for high-turbidity water sources (such as raw water with a turbidity of 3000 mg / L), traditional sludge removal systems struggle to quickly separate suspended particles, leading to uneven sludge deposition and requiring frequent manual intervention and maintenance, increasing operating costs.

[0003] In recent years, the industry has proposed several technological improvements to address the aforementioned issues. For example, patent CN110960912A achieves dynamic sludge removal by combining a spiral scraper with a filter cloth cylinder, but it still relies on external power and the filter cloth is prone to wear. Patent CN222250071U uses a motor-driven scraper to remove sludge from the inner wall of the tank, but it does not solve the problem of internal filter clogging. Another technology combines a centrifugal separation zone with a dynamic filter media filtration zone to shorten the purification time, but the sludge removal device still relies on gravity settling, resulting in limited sludge concentration efficiency and lacking integrated metal impurity adsorption functionality. In existing technologies, magnetization treatment is mostly used as an independent module and is not designed in conjunction with the sludge removal system, leading to residual metal particles that affect water quality. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency integrated sludge removal water purifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency sludge removal integrated water purifier, comprising:

[0006] The tank body has a filter screen cylinder for rinsing sewage through a fixed ring at the upper end of the tank body. The bottom of the filter screen cylinder has a vertical sewage pipe for discharging sludge in the sewage downwards. The filter screen cylinder has a cleaning spindle that is electrically driven to rotate and clean its inner wall.

[0007] An arc-shaped partition is provided, through which a drain pipe is installed to discharge sludge from the sewage downwards. A rotating main rod connected to the cleaning main shaft is vertically inserted inside the drain pipe. A magnetization chamber is formed at the upper end of the tank body, which contains rare earth strong magnetic strips that penetrate from the upper end of the tank body to adsorb and remove metal substances from the sewage.

[0008] Preferably, a motor is located at the center of the bottom of the tank, and the motor shaft is connected to the rotating main rod through a transmission. The top of the rotating main rod is connected to the lower end of the cleaning main shaft through a transmission. Driven directly by the motor, the cleaning main shaft can be continuously powered during the operation of the water purifier, realizing real-time cleaning of the inner wall of the filter screen cylinder without the need for additional equipment assistance.

[0009] Preferably, a long drain pipe is provided on one side of the lower end face of the filter cylinder, and the other end of the long drain pipe is connected to one side of the drain pipe. A short drain pipe is connected to the other side of the lower end face of the filter cylinder, and the other end of the short drain pipe is connected to the other side of the drain pipe, so that the sludge in the sewage can be quickly concentrated and discharged into the drain pipe through the long drain pipe and the short drain pipe.

[0010] Preferably, the tank has water inlets at the bottom of both sides of the exterior and water outlet at the top of one side of the exterior. The upper end of the sewage discharge pipe is spaced from the bottom of the filter screen cylinder to avoid interfering with the normal filtration water flow during sewage discharge, ensuring a continuous and stable purification process and solving the problem of turbidity fluctuations in the effluent caused by sludge discharge in traditional equipment.

[0011] Preferably, the upper end of the cleaning spindle is provided with cleaning support rods on both sides, and the other end of the cleaning support rod is fixed with an L-shaped brush rod, one end of which is fixedly connected to the lower end of the cleaning spindle on both sides. The brush rod is uniformly provided with cleaning brushes that adhere to the inner wall of the filter screen. The cleaning spindle is driven by a motor to drive the cleaning support rods and brushes, which can effectively remove the sludge attached to the inner wall of the filter screen, keep the filter screen transparent, and extend the service life of the filter screen.

[0012] Preferably, the upper part of the tank is provided with a conical baffle, and the top of the baffle is connected to the lower end of the magnetization chamber, which helps to guide the water flow into the magnetization chamber more rationally, so that the metal substances in the sewage can come into more full contact with the rare earth strong magnetic strips.

[0013] Preferably, the top of the tank is provided with a detachable cover plate by screws, and the lower end of the detachable cover plate is provided with a connecting rod extending into the tank body, and the lower end of the connecting rod is provided with a fixing strip plate. The rare earth strong magnetic strips are evenly distributed and fixed at the bottom of the fixing strip plate, and the rare earth strong magnetic strips are located inside the magnetization chamber. When the strong magnetic strips are saturated with adsorbed metal substances, they can be cleaned or replaced by removing the cover plate to ensure that the magnetization function remains effective.

[0014] Preferably, an electric drain port is provided on one side of the lower end face of the tank, and a manual drain port is provided on the corresponding side, providing dual drain options. The electric drain port can be used during normal operation of the equipment, which is efficient and convenient. In case of electric system failure or special circumstances, emergency sludge discharge can be carried out through the manual drain port, ensuring that the equipment can discharge sludge normally under various conditions.

[0015] Compared with existing technologies, the technical effects and advantages of this utility model are: This high-efficiency sludge removal integrated water purifier...

[0016] This invention uses a motor-driven cleaning spindle and related structures for sludge discharge, such as a long and short sludge discharge pipe and a sludge discharge rotary pipe, to quickly and centrally discharge sludge without relying on external power equipment. This solves the problem of low sludge discharge efficiency, reduces filter media clogging and effluent turbidity fluctuations caused by sludge deposition, and allows for continuous operation while reducing energy consumption.

[0017] This design utilizes a motor to drive the cleaning support rod and brushes, cleaning the inner wall of the filter screen in real time, maintaining filter permeability, extending filter life, eliminating the need for downtime maintenance, and reducing operating costs. Simultaneously, the design of inlets on both sides ensures that wastewater enters the tank evenly, and the spacing between the drain pipe and the bottom of the filter screen avoids interference with the normal filtered water flow, ensuring a continuous and stable purification process. This solves the problem of multiple small filters trapping various tiny adhesive substances that cannot be removed by backwashing, and the automatic brushes being unable to reach deep into the filter screen for cleaning, resulting in incomplete cleaning and ineffective filtration.

[0018] Existing technologies lack coordinated design between magnetization treatment and sludge removal systems, leading to metal particle residue. This invention incorporates a magnetization chamber inside the tank, guiding water flow through a conical baffle to ensure more thorough contact between metal substances in the wastewater and the rare-earth strong magnetic strips, thus improving the adsorption efficiency of metal impurities. Furthermore, the rare-earth strong magnetic strips are mounted on a detachable fixing plate for easy cleaning and replacement, ensuring continuous and effective magnetization. In addition, the dual electric and manual drain design further guarantees normal operation under various conditions, comprehensively enhancing the water purifier's wastewater purification capabilities.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency sludge removal integrated water purifier, comprising:

[0026] Tank 1 provides a closed space for wastewater purification and sludge removal. It has inlets 13 at the bottom of both sides to introduce wastewater to be purified; an outlet 14 at the top of one side allows purified water to flow out; a motor 10 is installed at the center of the bottom to power internal rotating parts; an electric drain 21 and a manual drain 22 are respectively located on the lower end face to discharge settled sludge. Inside the upper part of tank 1, a filter cylinder 3 for rinsing wastewater is installed via a fixing ring 2. The fixing ring 2, located at the upper part of the tank 1, provides stable support for the filter cylinder 3. By tightly fitting the inner wall of tank 1 to the outer wall of filter cylinder 3, the filter cylinder 3 is firmly fixed in a designated position inside tank 1, ensuring it does not shift during wastewater filtration. The filter cylinder 3 performs the initial rinsing and filtration of wastewater. A cleaning spindle 5 is rotatably installed inside the filter cylinder 3. When the cleaning spindle 5 rotates, cleaning brushes 16 scrub its inner wall to prevent sludge from clogging the filter.

[0027] The filter cylinder 3 is equipped with a cleaning spindle 5 that rotates electrically to clean its inner wall. Located inside the filter cylinder 3, the spindle 5 is connected to the top of the rotating main rod 8 via a through-drive connection at its bottom, and is driven by a motor 10. When the cleaning spindle 5 rotates, it drives the cleaning support rods 15 connected to both sides at its upper end to rotate synchronously. This causes the cleaning brushes 16 on the outside of the cleaning support rods 15, which are attached to the inner wall of the filter cylinder 3, to brush the inner wall of the filter screen, keeping it clean and maintaining good filtration performance.

[0028] An arc-shaped baffle 6, installed inside the tank 1, guides the water flow and sludge. A drain pipe 7 runs through the arc-shaped baffle 6, allowing sludge collected from the long drain pipe 11 and short drain pipe 12 to be smoothly discharged downwards through the drain pipe 7. Simultaneously, the shape of the arc-shaped baffle 6 helps guide water flow upwards into the magnetization chamber, optimizing the water flow path. The drain pipe 7, which discharges sludge downwards from the wastewater, runs through the arc-shaped baffle 6. Its upper end is connected to the bottom of the filter cylinder 3 via the long drain pipe 11 and short drain pipe 12, receiving sludge from the bottom of the filter cylinder 3 and discharging it downwards. The drain pipe 7 can rotate to a certain extent under the drive of the rotating main rod 8 (if required by design), assisting in sludge discharge and improving sludge discharge efficiency. The rotating main rod 8, which is driven by the cleaning main shaft 5, runs vertically through the drain pipe 7, with its upper end connected to the bottom of the cleaning main shaft 5. After the motor 10 starts, its shaft drives the rotating main rod 8 to rotate. The rotating main rod 8 then transmits power to the cleaning main shaft 5, causing the cleaning main shaft 5 to rotate. This, in turn, drives the cleaning support rod 15 and the cleaning brush 16 to clean the inner wall of the filter cylinder 3. Simultaneously, the rotating main rod 8 also provides rotational power to the sewage discharge pipe 7. A magnetization chamber is formed at the upper end of the tank 1, containing rare-earth strong magnetic strips 9 that penetrate from the upper end of the tank 1 to adsorb and remove metal substances from the sewage. Their function is to use strong magnetism to adsorb metal substances in the sewage. When sewage flows through the magnetization chamber, metal particles are adsorbed onto the surface of the rare-earth strong magnetic strips 9 under the influence of the magnetic field, thereby removing metal impurities from the sewage and improving the quality of the purified water.

[0029] A motor 10 is located at the center of the bottom of the tank 1, and the rotating shaft of the motor 10 is connected to the rotating main rod 8 through a transmission. The top end of the rotating main rod 8 is connected to the lower end of the cleaning main shaft 5 through a transmission, and the motor 10 is fixed at the center of the bottom of the tank 1. The motor 10 serves as the power source for the entire equipment, providing continuous rotational power to the rotating main rod 8 through the rotating shaft, thereby driving the cleaning main shaft 5 and related rotating parts, ensuring the normal operation of the equipment.

[0030] A long drain pipe 11 is provided on one side of the lower end face of the filter cylinder 3, and the other end of the long drain pipe 11 is connected to one side of the drain pipe 7. A short drain pipe 12 is connected to the other side of the lower end face of the filter cylinder 3, and the other end of the short drain pipe 12 is connected to the other side of the drain pipe 7. Their function is to collect sludge from different positions at the bottom of the filter cylinder 3 and guide it to the drain pipe 7. Through the design of different lengths, the bottom of the filter can be covered more comprehensively, ensuring that the sludge is discharged without any leakage.

[0031] The tank body 1 has water inlets 13 at the bottom of both sides of the exterior and water outlet 14 at the top of one side of the exterior. The upper end of the sewage discharge pipe 7 is spaced from the bottom of the filter screen cylinder 3.

[0032] The cleaning main shaft 5 has cleaning support rods 15 on both sides of its upper end, and an L-shaped brush rod 4 is fixed to the other end of the cleaning support rod 15. One end of the brush rod 4 is fixedly connected to the lower ends of the cleaning main shaft 5. Cleaning brushes 16 are evenly distributed on the outside of the brush rod 4 and adhere to the inner wall of the filter cylinder 3. The other end is fixed with an L-shaped structural component (which further fixes the cleaning brushes 16). When the cleaning main shaft 5 rotates, the cleaning support rods 15 and the brush rod 4 rotate accordingly, driving the cleaning brushes 16 to perform all-round brushing of the inner wall of the filter cylinder 3, effectively removing the sludge attached to the filter screen, ensuring the permeability of the filter screen. The cleaning brushes 16 evenly distributed on the outside of the cleaning support rod 15 and adhere to the inner wall of the filter cylinder 3, driven by the cleaning support rod 15, physically brush the inner wall of the filter screen, brushing off the attached sludge, allowing it to be smoothly discharged through the drain pipe 4, the long drain pipe 11, and the short drain pipe 12, maintaining the filtration performance of the filter screen.

[0033] The upper part of the tank 1 is provided with a conical baffle 17. The conical structure can guide the pre-filtered sewage to flow upward into the magnetization chamber in a uniform and orderly manner, so that the metal substances in the sewage can come into more full contact with the rare earth strong magnetic strip 9, thereby improving the adsorption effect of metal impurities. The top of the baffle 17 is connected to the bottom of the magnetization chamber.

[0034] A detachable cover plate 18 is provided at the top of the tank body 1 by screws, and its lower end face is connected to a connecting rod 19. The function of the detachable cover plate 18 is to facilitate the maintenance and replacement of the rare earth strong magnetic strips 9 inside the tank body 1, especially in the magnetization chamber. When it is necessary to clean or replace the rare earth strong magnetic strips 9, the screws can be unscrewed, the disassembly cover 18 can be removed, and then the relevant components can be operated. The lower end of the disassembly cover 18 is provided with a connecting rod 19 extending into the tank body 1. Its function is to connect the disassembly cover 18 and the fixing strip 20 into a whole. When the disassembly cover 18 is disassembled or installed, the connecting rod 19 drives the fixing strip 20 and the rare earth strong magnetic strips 9 fixed at its bottom to move synchronously, which facilitates the maintenance of the rare earth strong magnetic strips 9. The lower end of the connecting rod 19 is provided with the fixing strip 20, and the rare earth strong magnetic strips 9 are evenly fixed at the bottom of the fixing strip 20. The rare earth strong magnetic strips 9 are located inside the magnetization chamber and are connected to the disassembly cover 18 through the connecting rod 19. The bottom of the rare earth strong magnetic strips 9 is evenly fixed. The fixing strip 20 provides the installation foundation for the rare earth strong magnetic strips 9, ensuring that the rare earth strong magnetic strips 9 maintain a stable position in the magnetization chamber and can effectively adsorb metal substances in sewage.

[0035] An electric drain port 21 is provided on one side of the lower end face of the tank body 1. When the equipment is running normally and sludge needs to be discharged, the electric drain port 21 can be opened by the electric control system to automatically discharge the sludge settled at the bottom of the tank body 1, realizing efficient and convenient sludge discharge operation. A manual drain port 22 is provided on the opposite side of the electric drain port 21. When the electric drain port 21 malfunctions or the electric sludge discharge function cannot be used under special circumstances, the manual drain port 22 can be opened by manual operation to carry out emergency sludge discharge, ensuring that the equipment can complete the sludge discharge work normally under various conditions.

[0036] Specifically, during use, wastewater flows in from the inlet 13 at the bottom of both sides of the tank 1. Inside the tank 1, the water first enters the area equipped with the filter screen 3. The wastewater undergoes preliminary filtration through the filter screen 3, and the sludge in it will accumulate at the bottom of the filter screen 3 under the action of gravity. It will then be collected in the drain pipe 7 through the vertically installed drain pipe 4 at the bottom, as well as the long drain pipe 11 and short drain pipe 12 connected to both sides of the lower end face, and then discharged downwards.

[0037] At the same time, the motor 10 located at the center of the bottom of the tank 1 starts, and the rotating shaft of the motor 10 drives the rotating main rod 8 to rotate, which in turn drives the cleaning main shaft 5 to rotate. The cleaning support rods 15 and brush rods 4 on both sides of the upper end of the cleaning main shaft 5 rotate accordingly, and the cleaning brushes 16 installed on the outside of the brush rods 4 continuously brush the inner wall of the filter screen cylinder 3 to ensure that the filter screen is not clogged by sludge and to maintain a good filtration effect.

[0038] The wastewater, after initial filtration, continues to flow upwards into the magnetization chamber, guided by a conical baffle 17 at the upper end of the tank 1. As the wastewater flows through the magnetization chamber, metallic substances are adsorbed and removed by rare-earth magnetic strips 9, which are installed at the bottom of a fixed plate 20 and penetrate from the top of the tank 1. The fixed plate 20 is connected to a detachable cover plate 18 via a connecting rod 19, facilitating the cleaning and replacement of the rare-earth magnetic strips 9.

[0039] The purified water flows out from the outlet 14 at the upper end of the outer side of the tank 1. As for sludge removal, when sludge removal is required, it can be automatically removed through the electric drain port 21 on the lower end face of the tank 1; if the electric system fails, the manual drain port 22 on the corresponding side can be used for emergency sludge removal, thereby ensuring that the equipment can operate normally under various conditions and realizing the integrated function of efficient sludge removal and wastewater purification.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
