Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an industrial wastewater treatment device capable of multi-stage filtration. Background Technology

[0002] Industrial wastewater treatment processes, such as sedimentation, filtration, flotation, centrifugation, and filtration, treat wastewater with high levels of suspended solids, enabling it to meet environmental standards and achieve resource reuse.

[0003] According to Chinese Patent Publication No. CN222374415U, "An Industrial Wastewater Treatment Device with Multi-stage Filtration," the device mainly describes a system where wastewater and treatment agent flow into a tank in an alternating manner. This allows the wastewater and treatment agent to achieve a certain level of mixing upon entering the tank. Through the cooperation of a servo motor, rotating shaft, fixed plate, and blades, the wastewater and treatment agent can be quickly and evenly stirred and fully reacted. Then, through the cooperation of a base, filter plate, and handle, the filter plate can be pulled out to remove the filter residue. Through the cooperation of a mixing liquid tank and a mixing liquid outlet, the mixed liquid can flow evenly into the filter plate, thereby increasing the usable area of ​​the filter screen and improving the filtration efficiency.

[0004] Industrial wastewater is commonly filtered using a water-guiding structure combined with multiple detachable filter plates. However, during the filtration process, particulate matter in the industrial wastewater can easily get stuck in the mesh of the filter plates, reducing the filtration effect and affecting the filtration process. Utility Model Content

[0005] In view of the deficiencies in the existing technology, this utility model provides an industrial wastewater treatment device with multi-stage filtration to improve the filtration effect and reduce the obstruction of industrial processes caused by material blockage.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a multi-stage filtration industrial wastewater treatment device, including a treatment tank, a connecting pipe, a mixing tank, a sewage inlet pipe, a treatment agent inlet pipe, and a flap valve. A sealing plate is hinged to one side of the treatment tank. An adaptation groove is formed on the side of the treatment tank near the sealing plate. A U-shaped gasket frame is fixedly connected to the sealing plate at the corresponding position of the adaptation groove. A first groove is uniformly formed within the adaptation groove of the treatment tank. An inclined frame is provided between two adjacent first grooves. A rubber clip is contacted on one side of the inclined frame and fixedly connected to the sealing plate. The inclined frame has a U-shaped structure. A filter plate is fixedly connected inside the inclined frame. The filter plate has uniformly formed... The filter has a through hole, and a connecting plate is inserted into the first groove. An auxiliary rod is fixedly connected between two opposing connecting plates. A hidden groove is opened on the side of the connecting plate away from the auxiliary rod. A drive motor is fixedly connected to the connecting plate on the side of the hidden groove. A screw is fixedly connected to the output end of the drive motor. A slider is threaded onto the screw. There are two sliders. The other slider is slidably connected to the auxiliary rod. A water pump is fixedly connected to the bottom end of one of the sliders. A water distribution pipe is fixedly connected between the two sliders. Spray holes are evenly opened at the upper end of the water distribution pipe and the spray holes correspond to the bottom end of the filter plate. The output end of the water pump communicates with the inside of the water distribution pipe. A metal hose is fixedly connected to the water inlet end of the water pump.

[0007] As a preferred technical solution of this utility model, a filter cylinder is fixedly connected to the side of the metal hose away from the water pump. The filter cylinder has filter holes evenly distributed on it. The filter cylinder is in contact with the bottom side of the filter plate. By setting the filter cylinder and guiding it with the inclined frame, impurities in the water fall onto the inclined frame and the bottom side of the filter plate, so that some water is on the upper side of the filter plate. Therefore, during the water pumping process, impurities in the water on the upper side of the filter plate will not enter the water pump from the metal hose.

[0008] As a preferred technical solution of this utility model, a U-shaped guide frame is provided on the bottom side of the filter plate, and the upper end of the U-shaped guide frame is fixedly connected to the inclined frame. By setting the U-shaped guide frame, the contact between water and screw can be reduced.

[0009] As a preferred technical solution of this utility model, a support ball is rotatably embedded on the side of each of the two connecting plates that are far apart. The support ball contacts one side wall of the first groove. By setting the support ball, the contact area between the connecting plate and the first groove is reduced, making it easier to remove the inclined frame and filter plate for cleaning when the sealing plate is opened.

[0010] As a preferred technical solution of this utility model, a rubber handle is fixedly connected to the connecting plate. The rubber handle is located in the first groove. By setting the rubber handle and cooperating with the hidden groove, it is convenient to pull the connecting plate to move.

[0011] This invention has the following advantages: by setting multiple inclined frames and filter plates in the treatment box to provide filtration, and then driving the screw to rotate and causing the slider and water distribution pipe to move, and providing a backwashing effect on the other side of the filter plate, it can extend the maintenance cycle of the industrial wastewater treatment device, improve the filtration effect, and promote the filtration process of industrial wastewater.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The illustrated industrial wastewater treatment equipment with multi-stage filtration includes a treatment tank 1, a connecting pipe 2, a mixing tank 3, a wastewater inlet pipe 4, a treatment agent inlet pipe 5, and a flap valve 6. A servo motor is mounted on one side of the flap valve 6, and the servo motor is fixedly connected to one side of the connecting pipe 2. The servo motor drives the flap valve to rotate, thereby sealing the connecting pipe 2. The mixing tank 3 is used for mixing the treatment agent and wastewater. Both the wastewater inlet pipe 4 and the treatment agent inlet pipe 5 have the same structure as the flap valve 6, enabling control of water inflow and outflow. A sealing plate 7 is hinged to one side of the treatment tank 1. Both the sealing plate 7 and one side of the treatment tank 1 are equipped with connecting plates and are sealed by bolts. The treatment tank 1 is located near the sealing plate. A groove 8 is provided on one side of the sealing plate 7. A U-shaped pad frame is fixedly connected to the corresponding position of the sealing plate 7 and the groove 8. The treatment box 1 is fixedly connected within the groove 8 with uniformly spaced first grooves 11. An inclined frame 9 is provided between two adjacent first grooves 11. A rubber clip 24 contacts one side of the inclined frame 9. When the sealing plate 7 and the treatment box 1 are in contact, the rubber clip 24 can contact the upper and lower sides of the inclined frame 9, thereby reducing water leakage from different inclined frames 9. The rubber clip 24 is fixedly connected to the sealing plate 7. The inclined frame 9 has a U-shaped structure. Some impurities in the industrial wastewater get stuck in the mesh of the filter plate 10, which will cause some of the filtered water to remain at the lowest point of the filter plate 10. At a certain point, a certain liquid level is formed, and the water pumped by the water pump 17 is supplied from this point. A filter plate 10 is fixedly connected inside the inclined frame 9. The filter plate 10 has through holes evenly distributed (not shown in the figure, but structurally consistent with those used in the referenced document). A connecting plate 12 is inserted into the first groove 11. An auxiliary rod 14 is fixedly connected between two opposing connecting plates 12. A hidden groove 13 is opened on the side of the connecting plate 12 away from the auxiliary rod 14. A drive motor is fixedly connected to the side of the connecting plate 12 located in the hidden groove 13. The rotation of the drive motor drives the screw 15 to rotate, which can move the slider 16, thereby allowing the water distribution pipe 18 to move on the bottom side of the inclined frame 9 and the filter plate 10. A screw 15 is fixedly connected to the output end of the motor. A slider 16 is threaded onto the screw 15. There are two sliders 16. The other slider 16 is slidably connected to an auxiliary rod 14. A water pump 17 is fixedly connected to the bottom end of one of the sliders 16. The water pump 17 draws water from the lowest point at the top of the filter plate 10 and forms a backwashing structure, which can wash away debris stuck in the mesh of the filter plate 10. A water distribution pipe 18 is fixedly connected between the two sliders 16. The upper end of the water distribution pipe 18 is evenly provided with spray holes, and the spray holes correspond to the bottom end of the filter plate 10. The output end of the water pump 17 is connected to the inside of the water distribution pipe 18. A metal hose 19 is fixedly connected to one side of the water inlet end of the water pump 17.

[0018] Among them, the metal hose 19 is fixedly connected to the filter cylinder 20 on the side away from the water pump 17. The filter cylinder 20 has filter holes evenly opened on it. The filter cylinder 20 is in contact with the bottom side of the filter plate 10. By setting the filter cylinder 20, impurities contained in the water at the lowest point of the upper end of the filter plate 10 can be filtered, reducing the amount of impurities entering the water pump 17.

[0019] The filter plate 10 has a U-shaped guide frame 21 on its bottom side. The U-shaped guide frame 21 can reduce the direct contact between the water and the screw 15. The upper end of the U-shaped guide frame 21 is fixedly connected to the inclined frame 9. By setting the U-shaped guide frame 21, the filtered water can pass through, reducing the direct contact between the water and the screw 15. Furthermore, by installing folding sleeves on both sides of the slider 16, and fixing one side of the folding sleeve to the connecting plate 12, the water and impurities in the water can be prevented from contacting the screw 15.

[0020] In this case, a support ball 22 is rotatably embedded on the side of each of the two connecting plates 12 that are far apart. The support ball 22 contacts one side wall of the first groove 11. By setting the support ball 22, the contact surface between the first groove 11 and the connecting plate 12 is reduced, which can reduce the friction of the connecting plate 12 during movement.

[0021] A rubber handle 23 is fixedly connected to the connecting plate 12. The rubber handle 23 is located in the first groove 11. By setting the rubber handle 23, it is easy to pull the connecting plate 12.

[0022] The drive motor, servo motor, and water pump 17 used in some of the structures are all existing technologies, and protective covers have been installed to reduce direct water erosion of the water pump 17, drive motor, and servo motor. These components can be purchased on demand from the market.

[0023] Working principle: Industrial wastewater and treatment agent enter the mixing tank 3 together, and are mixed by the stirring rod driven by the drive motor. After a period of time, the flap valve 6 rotates and opens, and the water enters the treatment tank 1. Then, it passes through multiple inclined frames 9 and filter plates 10 to filter impurities in the water. Under the guidance of gravity, some debris and impurities are stuck at the lower points of the inclined frames 9 and filter plates 10, or some impurities accumulate or stick to the through holes at the lower points of the inclined frames 9 and filter plates 10. The flow rate of the wastewater to be treated decreases at this point. Water accumulates, and then the drive motor rotates the screw 15, which moves the slider 16 and the water distribution pipe 18. At the same time, the water pump 17 draws water from the lowest point at the top of the filter plate 10 and sprays it through the water distribution pipe 18 to the bottom of the filter plate 10, providing backwashing. This reduces debris and impurities stuck in the through holes of the filter plate 10. When disassembling, simply open the sealing plate 7 and pull the connecting plate 12 with the rubber handle 23 to disassemble and clean the connecting plate 12, filter plate 10, water pump 17, screw 15 and other components.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
