Description

Technical Field

[0001] This invention relates to the technical field of industrial wastewater treatment, and in particular to a circulating industrial wastewater treatment device. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater is diverse and complex in composition.

[0003] Industrial wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus making full use of water resources.

[0004] Chinese patent CN109912117A discloses an industrial wastewater treatment device. The device includes a vessel with an inlet at the top and an outlet at the bottom. The vessel's interior is divided into an upper and lower filter chamber and a reaction chamber by a partition. The bottom of the filter chamber is connected to the reaction chamber via a pipe equipped with a water pump. Filter screens are hinged to both sides of the inner wall of the filter chamber. When the bottoms of the two filter screens are in contact, they form a V-shaped filtration mechanism. A through hole is opened on the inner wall of the filter chamber below the filter screens. A limiting rod passes through the through hole and is fitted with a limiting plate on its body inside the filter chamber. A handwheel is provided at the outer end of the limiting rod. A compressed spring is fitted on the limiting rod between the inner wall of the filter chamber and the limiting plate. The end of the limiting rod inside the filter chamber contacts the filter screen. This invention has a simple structure and performs filtration and biological decomposition treatment on industrial wastewater after pH adjustment. It has a good filtration effect, and the filter screen is easy to clean and not easily clogged. The above-mentioned related technologies have the following defects: In the prior art, when separating impurities in wastewater through physical filtration, a filter structure is set up to separate particulate impurities in the wastewater. However, the particulate impurities in the wastewater are of different sizes. In order to reduce the number of residual particles in the wastewater, a filter mechanism with smaller sieve holes is used to filter the wastewater. As a result, larger particles accumulate rapidly on one side of the filter structure, and the filtration effect of the wastewater will decrease rapidly. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a circulating industrial wastewater treatment device.

[0006] The present invention provides a circulating industrial wastewater treatment device, which adopts the following technical solution: it includes a wastewater pipe and a treatment equipment tank. The wastewater pipe is installed and connected to the upper end of the treatment equipment tank. Multiple filter cylinders are coaxially arranged inside the treatment equipment tank. A fixed base is provided inside the treatment equipment tank. The lower end of each filter cylinder is fixed to the upper surface of the fixed base. A scraping mechanism is provided inside the treatment equipment tank. The lower end of the scraping mechanism slides in contact with the outer ring surface of each filter cylinder. The space above the scraping mechanism is only connected to the outer ring side of the outermost filter cylinder among the multiple filter cylinders. A turbine mechanism is installed inside the wastewater pipe, which drives the scraping mechanism to rotate after being impacted by water flow.

[0007] The upper surface of the fixed chassis has multiple vertically penetrating impurity grooves on the outer ring of each filter cylinder. An impurity aggregation cylinder is coaxially mounted at the lower end of the processing equipment barrel, and a rotatable water baffle is mounted at the upper end of the impurity aggregation cylinder. The water baffle is in rotatable contact with the bottom surface of the fixed chassis. A rotatable linkage ring is installed between the fixed chassis and the processing equipment barrel. The two ends of the linkage ring are fixed to the scraping mechanism and the water baffle, respectively. Water permeable holes are opened on the arc surface of the filter cylinder, and the diameter of the water permeable holes distributed on the surface of the multiple filter cylinders gradually decreases from the outside to the inside.

[0008] The upper surface of the baffle plate is provided with multiple drainage grooves on the outer ring side of each filter cylinder. The lower end of the drainage groove is connected to the inside of the impurity aggregation cylinder. A drain pipe is fixedly inserted into the inner side of the lower end of the innermost filter cylinder. The fixed base is fixedly sleeved on the outside of the drain pipe. The baffle plate is rotatably sleeved on the outside of the drain pipe. The drain pipe is coaxially fixed with the impurity aggregation cylinder.

[0009] Optionally, the turbine mechanism includes a turbine body and a shaft. The turbine body is installed inside the wastewater pipe. The turbine body and the shaft are coaxially mounted. The shaft and the scraping mechanism are coaxially mounted. The turbine body rotates under the impact of water flow through the shaft and the scraping mechanism.

[0010] Optionally, the scraping mechanism includes a top plate that slides in contact with the upper end face of each filter cylinder. The outer ring surface of the top plate has multiple notches, and the outermost filter cylinder among the multiple filter cylinders communicates with the notches of the top plate on its outer ring side.

[0011] The bottom surface of the top plate is fixedly installed with multiple scraping baffles on the outer ring side of each filter cylinder. The scraping baffles slide in contact with the adjacent filter cylinders, and the inner wall of the treatment equipment barrel slides in contact with the adjacent scraping baffles. The centers of the multiple scraping baffles are distributed one-to-one with the centers of the multiple sewage troughs. The lower end of the outermost scraping baffle connected to the top plate is fixed to the linkage ring.

[0012] Optionally, both the scraper baffle and the top plate are hollow, and the scraper baffle is connected to the inside of the top plate. A rotatable air inlet pipe is installed at the upper end of the top plate. The upper end of the air inlet pipe passes through the inside of the wastewater pipe. A shaft passes through the outer surface of the air inlet pipe and is fixed to the inner wall of the top plate. The shaft can rotate relative to the air inlet pipe.

[0013] The upper end of the intake pipe is horizontal and the lower end is vertical. The shaft is located in the vertical part of the intake pipe, which is coaxial with the top plate. A fan impeller is installed inside the vertical part of the intake pipe.

[0014] Optionally, the bottom surface of the scraper baffle is provided with air holes that communicate with its interior. The range of the air holes at the bottom of the scraper baffle corresponds to the range of the impurity trough, and the size of the sewage discharge trough is adapted to the range of the impurity trough.

[0015] The width of the upper end of the scraper baffle is smaller than the width of its lower end, and the range between the lower ends of two adjacent scraper baffles that are in contact with the outer wall of the same filter cylinder is adapted to the range of the sewage trough.

[0016] Optionally, the water baffle plate has a central hole inside, the inside of the sewage trough is not connected to the inside of the water baffle plate, the inside of the water baffle plate is connected to the inside of the drain pipe, and a water leakage hole is opened on the upper surface of the water baffle plate and connected to the inside of the water leakage hole. The inner diameter of the water leakage hole is smaller than the minimum inner diameter of the water permeable hole.

[0017] Optionally, an external gear ring is installed on the outer ring surface of the linkage ring, and a gear meshes on the outer ring surface of the external gear ring. A motor that controls the rotation of the gear is installed on the outside of the processing equipment barrel, and a wireless speed sensing controller that controls the motor start by detecting the shaft speed is installed inside the air inlet pipe.

[0018] Optionally, a pressure-concentrating cylinder is installed inside the wastewater pipe. The pressure-concentrating cylinder is located on the upper side of the turbine body, and the inner annular surface of the pressure-concentrating cylinder is conical. The lower end of the inner wall of the pressure-concentrating cylinder is the small-diameter end.

[0019] In summary, the present invention has the following beneficial technical effects: This invention utilizes a combination of components such as multi-layered filter cylinders, water-permeable holes with gradually decreasing diameters from the outside to the inside, and a scraping mechanism. Initial wastewater is discharged into the outermost filter cylinder, allowing it to flow sequentially from the outermost to the innermost filter cylinder. The gradually decreasing diameter water-permeable holes progressively layer and block particles on the outer sides of the corresponding filter cylinders. As the scraping mechanism and baffle plate rotate, and the impurity trough connects with the sewage discharge trough, impurities filtered on the outer side of the filter cylinders are discharged into the impurity aggregation cylinder, enabling the filter cylinders to circulate and filter the wastewater.

[0020] This invention, through the coordination of components such as a fan impeller, a scraper baffle with air holes at the bottom, and an air inlet pipe, allows the turbine body to rotate as the shaft rotates due to the impact of water flow. The shaft then drives the fan impeller to rotate within the air inlet pipe. When the scraper baffle and the wastewater discharge trough rotate to connect with the impurity trough, the airflow entering the top plate and the scraper baffle is injected into the lower impurity trough through the air holes, assisting in pushing out the impurities in the impurity trough. This facilitates the impurity trough to accommodate the impurities filtered by the filter cartridge again when it is misaligned with the scraper baffle. Attached Figure Description

Detailed Implementation

[0023] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0024] This invention discloses a circulating industrial wastewater treatment device. For example... Figures 1-7 As shown, it includes a wastewater pipe 1 and a treatment equipment tank 3. The wastewater pipe 1 is installed and connected to the upper end of the treatment equipment tank 3. The end of the wastewater pipe 1 away from the treatment equipment tank 3 is connected to a wastewater supply device. Multiple filter cylinders 2 are coaxially arranged inside the treatment equipment tank 3. The multiple filter cylinders 2 are arranged with equal gaps. A fixed base 4 is provided inside the treatment equipment tank 3. The lower end of each filter cylinder 2 is fixed to the upper surface of the fixed base 4.

[0025] A scraping mechanism 5 is provided inside the treatment equipment tank 3. The lower end of the scraping mechanism 5 slides in contact with the outer ring surface of each filter cylinder 2. The space above the scraping mechanism 5 is only connected to the outer ring side of the outermost filter cylinder 2 among the multiple filter cylinders 2. The wastewater provided by the wastewater pipe 1 flows into the space between the outermost filter cylinder 2 and the treatment equipment tank 3 through the upper side of the scraping mechanism 5. At the same time, the scraping mechanism 5 blocks the upper end of the filter cylinders 2 distributed on the inner side. A turbine mechanism 6 is installed inside the wastewater pipe 1, which drives the scraping mechanism 5 to rotate after being impacted by the water flow.

[0026] The turbine mechanism 6 includes a turbine body 61 and a shaft 62. The turbine body 61 is installed inside the wastewater pipe 1. The turbine body 61 and the shaft 62 are coaxially mounted. The turbine body 61 is made of polytetrafluoroethylene (PTFE), which is suitable for highly corrosive wastewater environments. It has extremely strong acid and alkali resistance and wear resistance, and can maintain its precision for a long time. The shaft 62 is coaxially mounted with the scraping mechanism 5. The turbine body 61 rotates through the shaft 62 and the scraping mechanism 5 when impacted by water flow.

[0027] A pressure-concentrating cylinder 612 is installed inside the wastewater pipe 1. The pressure-concentrating cylinder 612 is located on the upper side of the turbine body 61. The inner ring of the pressure-concentrating cylinder 612 is conical. The lower end of the inner wall of the pressure-concentrating cylinder 612 is the small diameter end. The maximum outer diameter of the turbine body 61 is matched with the inner diameter of the corresponding position of the wastewater pipe 1, so that the water flow can fully impact the turbine body 61 and drive it to rotate.

[0028] Multiple vertically connected impurity grooves 7 are provided on the upper surface of the fixed base 4 on the outer ring of each filter cylinder 2. Impurities blocked by each layer of filter cylinder 2 fall into the impurity groove 7 on the outer side of the corresponding filter cylinder 2.

[0029] The lower end of the processing equipment tank 3 is coaxially mounted with an impurity aggregation cylinder 9. The upper end of the impurity aggregation cylinder 9 is mounted with a rotatable baffle plate 8. The baffle plate 8 is in rotatable contact with the bottom surface of the fixed base 4. A rotatable linkage ring 10 is installed between the fixed base 4 and the processing equipment tank 3. The two ends of the linkage ring 10 are fixed to the scraping mechanism 5 and the baffle plate 8, respectively. The arc surface of the filter cylinder 2 is provided with water permeable holes 11. The diameter of the water permeable holes 11 distributed on the surface of multiple filter cylinders 2 gradually decreases from the outside to the inside, so that impurities of different particles are blocked in layers on the outside of different filter cylinders 2.

[0030] In this embodiment, the inner side of the lower end of the impurity polymerization cylinder 9 is shaped like a cone, the upper end of the inner side of the impurity polymerization cylinder 9 is a small diameter end, and an opening is provided on the outer side of the lower end of the impurity polymerization cylinder 9 to remove internal impurities.

[0031] The scraping mechanism 5 includes a top plate 51, which slides in contact with the upper end face of each filter cylinder 2. The outer ring surface of the top plate 51 has multiple notches. The outer ring side of the outermost filter cylinder 2 is connected to the notch of the top plate 51. Wastewater flowing to the upper side of the top plate 51 flows through the notch between the outermost filter cylinder 2 and the treatment equipment tank 3.

[0032] Multiple drain troughs 12 are provided on the upper surface of the baffle plate 8 on the outer ring side of each filter cylinder 2. The lower end of the drain trough 12 is connected to the inside of the impurity aggregation cylinder 9.

[0033] Multiple scraper baffles 52 are fixedly installed on the bottom surface of the top plate 51 on the outer ring side of each filter cylinder 2. The scraper baffles 52 slide in contact with the adjacent filter cylinder 2. As the scraper baffles 52 rotate relative to the filter cylinder 2, they can clean the impurities attached to the outside of the corresponding filter cylinder 2, so that the water permeable holes 11 always have good water permeability. The inner wall of the treatment equipment tank 3 slides in contact with the adjacent scraper baffles 52. The centers of the multiple scraper baffles 52 are distributed one-to-one with the centers of the multiple sewage troughs 12, so that the scraper baffles 52 and the sewage trough 12 are simultaneously connected to or misaligned with the impurity trough 7. At the same time, the width of the bottom of the scraper baffles 52 ensures that the impurity trough 7 is not simultaneously connected to the sewage trough 12 and the outside of the scraper baffles 52, ensuring that wastewater does not flow directly into the impurity aggregation cylinder 9 through the sewage trough 12 and the impurity trough 7. The lower end of the outermost scraper baffle 52 connected to the top plate 51 is fixed to the linkage ring 10.

[0034] A drain pipe 13 is fixedly inserted into the innermost part of the filter cylinder 2. Water filtered by the innermost filter cylinder 2 is discharged from the drain pipe 13. The fixed base 4 is fixedly sleeved on the outside of the drain pipe 13. The water baffle 8 is rotatably sleeved on the outside of the drain pipe 13. The drain pipe 13 is coaxially fixed with the impurity aggregation cylinder 9.

[0035] Both the scraper baffle 52 and the top plate 51 have a central hole. The scraper baffle 52 is connected to the top plate 51. A rotatable air inlet pipe 53 is installed on the upper end of the top plate 51, allowing external air to enter the top plate 51 through the air inlet pipe 53. The upper end of the air inlet pipe 53 passes through the wastewater pipe 1. The shaft 62 passes through the outer surface of the air inlet pipe 53 and is fixed to the inner wall of the top plate 51. A shaft seal and bearing are installed at the connection between the shaft 62 and the air inlet pipe 53, allowing the shaft 62 to rotate relative to the air inlet pipe 53.

[0036] The upper end of the intake pipe 53 is horizontal and the lower end is vertical. The shaft 62 is located in the vertical part of the intake pipe 53. The vertical part of the intake pipe 53 is coaxially arranged with the top plate 51. The fan impeller 54 is installed inside the vertical part of the intake pipe 53. When the turbine body 61 is impacted by the water flow and rotates, it drives the fan impeller 54 to rotate through the shaft 62. When the fan impeller 54 rotates, it draws external air into the intake pipe 53 and the top plate 51.

[0037] The interior of the baffle plate 8 is shaped like a central hole. The interior of the drain trough 12 is not connected to the interior of the baffle plate 8. The interior of the baffle plate 8 is connected to the interior of the drain pipe 13. When the baffle plate 8 rotates, the water inside can be discharged into the drain pipe 13. A water leakage hole is opened on the upper surface of the baffle plate 8 and is connected to its interior. The inner diameter of the water leakage hole is smaller than the minimum inner diameter of the water permeable hole 11, ensuring that only water can enter the interior of the baffle plate 8 through the water leakage hole. When the impurity trough 7 and the drain trough 12 are misaligned, the impurity trough 7 is partially connected to the water leakage hole of the baffle plate 8, so that the water flowing into the impurity trough 7 can be discharged into the drain pipe 13 through the water leakage hole and the interior of the baffle plate 8.

[0038] In this embodiment, the bottom surface of the scraper baffle 52 is provided with air holes that communicate with its interior. The range of the air holes at the bottom of the scraper baffle 52 corresponds to the range of the impurity trough 7, and the size of the drain trough 12 is adapted to the range of the impurity trough 7.

[0039] When the impurity tank 7 is connected to the drain tank 12, the impurity tank 7 overlaps with the range of the air hole, so that the airflow entering the scraper baffle 52 is filled into the impurity tank 7 through the air hole, which helps to push the impurities in the impurity tank 7 into the impurity aggregation cylinder 9 through the drain tank 12.

[0040] The upper width of the scraper baffle 52 is smaller than its lower width. The connection between the two ends of the scraper baffle 52 is rounded to prevent impurities from accumulating in dead corners. The narrower upper width of the scraper baffle 52 increases the flow rate of the incoming water. The range between the lower ends of two adjacent scraper baffles 52 that are in contact with the outer wall of the same filter cylinder 2 is matched with the range of the drain trough 12. The impurities blocked by the filter cylinder 2 fall into the corresponding impurity trough 7 through the space between two adjacent scraper baffles 52. As the impurity trough 7 alternates with the scraper baffle 52 through misalignment and overlap, the impurities blocked by the filter cylinder 2 are continuously discharged, so that the filter cylinder 2 can continuously maintain a large filtration effect.

[0041] An external gear ring 621 is installed on the outer ring surface of the linkage ring 10. A gear 622 meshes with the outer ring surface of the external gear ring 621. A motor 623 that controls the rotation of the gear 622 is installed on the outside of the treatment equipment tank 3. A wireless speed sensor controller 624 that controls the start of the motor 623 by detecting the speed of the shaft 62 is installed in the air inlet pipe 53. By setting the parameters of the wireless speed sensor controller 624, after the speed of the shaft 62 decreases to a certain value or stops, the wireless speed sensor controller 624 controls the motor 623 to start. Through the meshing of the gear 622 and the external gear ring 621, the linkage ring 10 and the connected scraper baffle 52 and baffle plate 8 are actively driven to rotate, ensuring that the scraper baffle 52 and baffle plate 8 can continue to rotate and work even when the power generated by the wastewater flow rate is insufficient.

[0042] The working principle is as follows: the wastewater pipe 1 carries the initial wastewater through the turbine mechanism 6 and into the upper side of the scraping mechanism 5. Then the wastewater enters the outermost filter cylinder 2, causing the wastewater to flow from the outermost filter cylinder 2 to the innermost filter cylinder 2. The water-permeable holes 11, whose diameter gradually decreases from the outside to the inside, gradually block the particles in layers on the outside of the corresponding filter cylinder 2. The impurity tank 7 contains the impurities blocked by the corresponding filter cylinder 2. The scraping mechanism 5 drives the baffle plate 8 to rotate through the linkage ring 10. When the impurity tank 7 is connected to the sewage discharge tank 12, the impurities contained in the impurity tank 7 fall into the impurity aggregation cylinder 9 through the sewage discharge tank 12, so that the filter cylinder 2 can continuously filter the wastewater for a long time. At the same time, the impurity tank 7 can circulate and contain the impurities filtered by the filter cylinder 2.

[0043] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
