Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater reuse device with filtration function. Background Technology

[0002] In the production and electroplating process of automotive parts, wastewater containing heavy metal ions and organic pollutants is generated. If this wastewater is discharged directly to the outside without effective treatment, it will not only cause serious pollution to the environment, but also waste a lot of water resources. Therefore, wastewater or sewage needs to be treated before it can be reused in the production system. This water is called recycled water. In the process of filtering sewage, filter screens are used to filter impurities. However, after a long period of use, impurities will adhere to the outer surface of the filter screen. Over time, the pores of the filter screen will gradually shrink, which will seriously affect the subsequent filtration efficiency of sewage. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater reuse device with filtration function to solve the problem mentioned in the background art that the filter screen is easily clogged and affects subsequent wastewater filtration.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater reuse device with filtration function, comprising a housing, the housing being cylindrical, and a filter box being fixedly installed on the outer surface of the housing. A motor is fixedly installed on the outer surface of the filter box, and the output end of the motor penetrates through the outer surface of the filter box. A filter screen is rotatably installed inside the housing, and a toothed ring is fixedly installed on the outer surface of the filter screen. The toothed ring and the filter screen are concentrically designed. A rotating engagement mechanism is provided between the filter screen and the filter box, and the filter screen is cleaned by the rotating engagement mechanism.

[0005] Preferably, the rotating engagement mechanism includes: a scraper plate, which is slidably mounted on the outer surface of the filter box, the outer surface of the scraper plate is in contact with the outer surface of the filter screen, a gear is fixedly mounted on the output end of the motor, and the gear is located inside the box, the gear meshes with the gear ring, and the outer surface of the scraper plate engages with the filter box.

[0006] By adopting the above technical solution, the rotation of the motor can drive the gear to rotate together, so that the gear ring meshing with the gear can rotate along with it, allowing the filter screen to rotate. While the filter screen is rotating, the scraper plate can brush and wash the filter screen, keeping the filter screen clean at all times. At the same time, the rotation of the filter screen prevents wastewater from being filtered in only one place when it falls, keeping the filter screen clean at all times and ensuring the water flow during wastewater treatment and filtration.

[0007] Preferably, an electric push rod is fixedly installed on the outer surface of the filter box near the motor, a filter screen frame is slidably installed inside the filter box, and the inside of the filter screen frame is inclined. A movable door is rotatably installed on one outer surface of the filter screen frame, and the movable door engages with the filter screen frame. A sludge inlet pipe is opened on the outer surface of the end of the filter box away from the electric push rod, and the sludge inlet pipe is higher than the side surface of the filter screen frame.

[0008] Using the above technical solution, the wastewater discharged into the filter box can be coarsely filtered through the filter screen frame, allowing large particles such as plastics in the wastewater to be filtered out, reducing the filtration pressure on the filter screen disc. After a period of use, the filter screen frame can be pushed out by an electric push rod, and the inclined design inside the filter screen frame allows large particles to be gathered together. Filtration can continue even after the filter screen frame is pushed out. Subsequently, the inside of the filter screen frame can be cleaned, allowing debris to be swept out through the movable door.

[0009] Preferably, the filter screen is designed in the shape of a bucket, and a hollow connecting tube is fixedly installed on the outer surface of the filter screen. A pushing and sliding mechanism is provided between the hollow connecting tube and the scraper plate, and the dirt washed off by the brush can be cleaned by pushing and sliding mechanism.

[0010] By adopting the above technical solution, the funnel-shaped design of the filter screen can easily collect the filtered dirt through the flowing water, and facilitate the discharge of the filtered dirt from the hollow connecting tube, allowing the dirt to be easily discharged outwards.

[0011] Preferably, the pushing and sliding mechanism includes: an electric actuator assembly, which is fixedly installed on the side surface of the filter box, and the outer surface of the filter box is slidably connected to the output end of the electric actuator assembly; a spring is provided between the scraper plate and the filter box, and the spring is in contact with the outer surface of the filter box and the scraper plate; the outer surface of the scraper plate is in contact with the outer surface of the hollow connecting tube; and the outer surface of the scraper plate is in contact with the outer surface of the output end of the electric actuator assembly.

[0012] By adopting the above technical solution, the cleaning power of the scraper plate on the filter screen will not decrease after long-term use. The fit of the scraper plate to the sewage inlet pipe prevents the flowing sewage from entering the interior of the box through the hollow connecting pipe. Furthermore, the use of the electric push rod assembly makes it easy to discharge the scrubbed dirt.

[0013] Preferably, a mixing rod is fixedly installed on the outer surface of the hollow connecting tube, and the mixing rod is in contact with the outer surface of the box. A sludge collection trough is provided on the outer surface of the box, and the sludge collection trough and the box are concentrically designed. A rotating mechanism is provided inside the box, which allows the hollow connecting tube to rotate more smoothly and facilitates the discharge of dirt sediment.

[0014] Using the above technical solution, the mixing rod can be driven to rotate at the same time as the filter screen, which facilitates the stirring of the sewage inside the tank, speeds up the mixing speed of the flocculant and sewage and mixes them evenly, so that the flocculant can combine with the dirt in the sewage more quickly, and the dirt can be concentrated into the inside of the sludge collection tank by the stirring water flow, so that the treated sewage above can be discharged outward.

[0015] Preferably, the rotating mechanism includes: a support frame, which is fixedly installed inside the sludge collection tank, and the sludge collection tank and the support frame are concentrically designed; the support frame is rotatably connected to the hollow connecting tube; a through hole is opened at one end of the hollow connecting tube near the support frame, and a through hole is opened on the side of the support frame away from the hollow connecting tube; a solenoid valve pipe is fixedly installed on the outer surface of the sludge collection tank, and the solenoid valve pipe and the support frame are concentrically designed; and an inlet pipe is fixedly opened on the outer surface of the housing, and one end of the inlet pipe penetrates the outer surface of the filter box.

[0016] Using the above technical solution, the through holes on the outer surface of the hollow coupling tube allow the cleaned dirt to be discharged into the inside of the dirt collection tank. At the same time, the support frame makes the filter screen more secure and rotates more smoothly. And the dirt and flocculated matter can be conveniently discharged from the dirt collection tank through the solenoid valve pipeline.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the wastewater reuse equipment with filtration function:

[0018] 1. After the wastewater passes through the coarse filter, it enters the interior of the filter screen for secondary filtration. As the motor rotates, it drives the gear to rotate, which in turn drives the filter screen to rotate. This allows the filter screen to come into contact with the scraper plate as it rotates, enabling the scraper plate to scrub the filter screen and keep its outer surface clean, thus ensuring the filter screen can filter through at a certain flow rate.

[0019] 2. The spring-driven scraper plate keeps the filter screen in close contact with the outer surface of the filter screen at all times. This ensures that even after prolonged scrubbing, the scraper plate will not lose contact with the filter screen due to wear, guaranteeing that the filter screen can still be cleaned after long-term use. At the same time, the spring-driven scraper plate can seal the hollow connecting pipe, preventing unfiltered wastewater from entering the interior of the housing. When it is necessary to clean the particles brushed off inside the filter screen, simply activate the electric push rod assembly to push the scraper plate upward, allowing the particles to be discharged into the sludge collection tank along with the flushing water. The particles are then discharged outward through the opening of the solenoid valve pipe, making it convenient to clean the filtered particles while maintaining the long-term scrubbing effect of the scraper plate and the filter screen.

[0020] 3. Wastewater is discharged into the filter box through the inlet pipe and filtered through the filter screen to remove large particles. The inclined design of the filter screen concentrates the debris. When cleaning the inside of the filter screen is required, simply activate the electric push rod to push out a portion of the filter screen. Then, tools can be used to clean the inside of the filter screen, and large particles can be easily swept out through the movable door. Pushing the filter screen halfway out allows a small amount of wastewater to still be filtered, ensuring that wastewater treatment does not stop while cleaning is being performed.

[0028] 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.

[0029] Please see Figure 1-6This utility model provides a technical solution: a wastewater reuse device with filtration function, including a box 1, which is cylindrical, and a filter box 2 is fixedly installed on the outer surface of the box 1. A motor 9 is fixedly installed on the outer surface of the filter box 2, and the output end of the motor 9 passes through the outer surface of the filter box 2. A filter screen 7 is rotatably installed inside the box 1. A toothed ring 8 is fixedly installed on the outer surface of the filter screen 7, and the toothed ring 8 and the filter screen 7 are concentrically designed. A rotating engagement mechanism is provided between the filter screen 7 and the filter box 2, and the filter screen 7 is cleaned by the rotating engagement mechanism.

[0030] The filter screen 7 allows for secondary filtration of wastewater to remove small particulate impurities and reduce the time required for subsequent water treatment flocculation.

[0031] The rotating meshing mechanism includes: a scraper plate 11, which is slidably mounted on the outer surface of the filter box 2. The outer surface of the scraper plate 11 is in contact with the outer surface of the filter screen 7. A gear 10 is fixedly mounted on the output end of the motor 9, and the gear 10 is located inside the box 1. The gear 10 meshes with the gear ring 8, and the outer surface of the scraper plate 11 is engaged with the filter box 2.

[0032] After the motor 9 starts, it will drive the gear 10 to rotate, so that the gear ring 8 that meshes with the gear 10 can rotate along with it, driving the filter screen 7 to rotate. As the filter screen 7 rotates, the outer surface of the filter screen 7 will be cleaned and scrubbed by the scraper plate 11, allowing the filter screen 7 to rotate and be scrubbed, ensuring the cleanliness of the filter screen 7. At the same time, the surface in contact with the sewage is constantly changing, so that the flow rate of the filter screen 7 can be kept at the optimal level.

[0033] An electric push rod 4 is fixedly installed on the outer surface of the filter box 2 near the motor 9. A filter screen frame 5 is slidably installed inside the filter box 2, and the filter screen frame 5 has an inclined design. A movable door 6 is rotatably installed on one outer surface of the filter screen frame 5, and the movable door 6 engages with the filter screen frame 5. A dirt inlet pipe 3 is opened on the outer surface of the end of the filter box 2 away from the electric push rod 4, and the dirt inlet pipe 3 is higher than the side surface of the filter screen frame 5.

[0034] The filter screen frame 5 can filter the sewage discharged through the sewage inlet pipe 3, remove large particles of debris from the sewage, reduce the processing difficulty of the filter screen disc 7, and reduce the chance of clogging of the hollow connecting pipe 13. At the same time, the electric push rod 4 can push the filter screen frame 5 to move and extend, allowing the movable door 6 to leak out of the filter box 2. The inclined design inside the filter box 2 can gather large particles of debris together, and after the filter screen frame 5 is pushed out part of its length, it is convenient to clean the debris inside and push the debris out through the movable door 6. This facilitates cleaning while allowing sewage to still be filtered through the filter screen frame 5.

[0035] The filter screen 7 has a bucket-shaped design, and a hollow connecting tube 13 is fixedly installed on the outer surface of the filter screen 7. A pushing and sliding mechanism is provided between the hollow connecting tube 13 and the scraper plate 11. The dirt washed off by the brush can be cleaned by pushing and sliding mechanism.

[0036] The funnel-shaped design of the filter disc 7 allows the particles washed off by the filter to be more easily collected, rather than scattered throughout the filter disc 7.

[0037] The sliding mechanism includes an electric actuator assembly 19, which is fixedly mounted on the side surface of the filter box 2. The outer surface of the filter box 2 is slidably connected to the output end of the electric actuator assembly 19. A spring 12 passes through the scraper plate 11 and the filter box 2. The spring 12 is in contact with the outer surface of the filter box 2 and the scraper plate 11. The outer surface of the scraper plate 11 is in contact with the outer surface of the hollow connecting tube 13. The outer surface of the scraper plate 11 is in contact with the outer surface of the output end of the electric actuator assembly 19.

[0038] The scraper plate 11 is pushed by the spring 12, so that the scraper plate 11 can always be in close contact with the outer surface of the filter screen 7, so that the scraper plate 11 can always brush the filter screen 7 without failing. At the same time, by activating the electric push rod assembly 19, the scraper plate 11 can be driven to rise, so that the scraper plate 11 can be disengaged from the hollow connecting tube 13, allowing the particles gathered by the filter brush to be discharged through the hollow connecting tube 13, preventing unfiltered sewage from entering the housing 1. While maintaining the brushing of the filter screen 7, it is convenient to remove impurities and prevent leakage.

[0039] A mixing rod 14 is fixedly installed on the outer surface of the hollow connecting tube 13, and the mixing rod 14 is in contact with the outer surface of the box 1. A sludge collection tank 16 is provided on the outer surface of the box 1, and the sludge collection tank 16 is concentric with the box 1. A rotating mechanism is provided inside the box 1, which allows the hollow connecting tube 13 to rotate more smoothly and facilitates the discharge of dirt sediment.

[0040] As the filter screen 7 rotates, the hollow connecting pipe 13 and the mixing rod 14 will rotate together. The rotation of the mixing rod 14 allows the flocculant discharged into the tank 1 through the liquid inlet pipe 18 to be evenly mixed, improving the mixing uniformity of wastewater and flocculant, and accelerating the flocculation speed. The mixing rod 14 agitates the wastewater, allowing the flocculated impurities to be collected in the sludge collection tank 16, which is convenient for subsequent discharge through the solenoid valve pipe 17. This facilitates use and allows the treated water to be discharged from one side of the tank 1.

[0041] The rotating mechanism includes: a support frame 15, which is fixedly installed inside the sludge collection tank 16 and is concentric with the sludge collection tank 16. The support frame 15 is rotatably connected to the hollow connecting tube 13. The hollow connecting tube 13 has a through hole at one end near the support frame 15 and a through hole at the other side of the support frame 15 away from the hollow connecting tube 13. A solenoid valve pipe 17 is fixedly installed on the outer surface of the sludge collection tank 16 and is concentric with the support frame 15. An inlet pipe 18 is fixedly opened on the outer surface of the housing 1 and one end of the inlet pipe 18 penetrates the outer surface of the filter box 2.

[0042] The particles filtered and washed by the filter screen 7 can be discharged into the collection tank 16 through the through hole of the hollow connecting tube 13. The support frame 15 can make the filter screen 7 more stable when rotating and ensure that the hollow connecting tube 13 will not shift its position as it rotates.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
