Description

Technical Field

[0001] This utility model relates to the technical field of solid-liquid separators for industrial wastewater pretreatment, specifically a solid-liquid separator for industrial wastewater pretreatment. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production processes. It contains industrial production materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater is characterized by its wide variety, complex composition, and serious hazards. Among these hazards are water pollution and ecosystem damage. Therefore, industrial wastewater needs to be treated. Before treatment, solid-liquid separators are used for pretreatment to achieve solid-liquid separation.

[0003] A solid-liquid separator is a device specifically designed to separate solid particles or suspended matter from a liquid. In industrial wastewater pretreatment, the main function of a solid-liquid separator is to effectively remove solid impurities and particulate matter from wastewater through physical or mechanical means, thereby purifying the water quality and achieving solid-liquid separation of industrial wastewater, which facilitates subsequent treatment processes for industrial wastewater.

[0004] Currently, when using solid-liquid separators for the pretreatment of industrial wastewater, the industrial wastewater can be fed into the device first, and then the internal separation structure can be used to achieve solid-liquid separation. After the separation is completed, the solids inside the device need to be cleaned to prevent them from accumulating too much and affecting the use of the device.

[0005] However, most solid-liquid separators cannot continuously treat wastewater. After each treatment period, the solids inside need to be cleaned, which can reduce the efficiency of solid-liquid separation pretreatment of industrial wastewater and affect the continuity and stability of wastewater treatment. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a solid-liquid separator for industrial wastewater pretreatment, in order to solve the technical problem that most solid-liquid separators cannot continuously treat wastewater, and the solids inside need to be cleaned after each treatment period, which easily reduces the working efficiency of solid-liquid separation pretreatment of industrial wastewater and affects the continuity and stability of wastewater treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separator for industrial wastewater pretreatment, comprising a housing, a partition fixedly connected inside the housing, and a first movable block rotatably connected to the surface of the partition. Second movable blocks are rotatably connected to both ends of the housing. A rotating shaft is rotatably connected between a group of second movable blocks, and the rotating shaft is rotatably connected to the first movable block. A conical filter cylinder is fixedly connected to the surface of the rotating shaft via multiple sets of connecting rods. A connecting shaft is rotatably connected to one end of each conical filter cylinder. A meshing gear is fixedly connected to the surface of each connecting shaft. A spiral blade meshing with the inner wall of the conical filter cylinder is provided on the surface of each connecting shaft. One end of each connecting shaft movably penetrates the surface of the first movable block and one of the second movable blocks and extends to the outside for connection.

[0008] By adopting the above technical solution, when the drive shaft rotates, the positions of multiple conical filter cylinders can be adjusted simultaneously until one of them moves to the inlet position, facilitating the delivery of industrial wastewater into it. After the industrial wastewater is delivered to the corresponding conical filter cylinder, the connecting shaft can be driven to rotate, causing the spiral blades to rotate against the inner wall of the conical filter cylinder. This allows the liquid in the industrial wastewater to be discharged through the conical filter cylinder, while the solids are delivered to one end of the conical filter cylinder. Then, the drive shaft rotates again, causing another conical filter cylinder to reach the inlet position. The connecting shaft and spiral blades then perform solid-liquid separation of the industrial wastewater. While the connecting shaft drives the spiral blades to deliver solids, gears can cause other connecting shafts to drive corresponding spiral blades to rotate, discharging solids from other conical filter cylinders. This structure allows for continuous solid-liquid separation of industrial wastewater, improving work efficiency. Furthermore, the cooperation between the connecting shaft and the spiral blades enables solid-liquid separation, thus improving wastewater treatment quality.

[0009] The present invention is further configured such that a sliding groove is provided on the surface of the partition and at both ends of the box body, and a slider that fits into the sliding groove is slidably connected in each sliding groove, and each slider is fixedly connected to the surface of the corresponding first movable block or second movable block.

[0010] By adopting the above technical solution, the design of the chute and slider can increase the stability of the first and second movable blocks in the movement of the box or partition, making it easier to use the device.

[0011] The present invention is further configured such that one end of each of the conical filter cylinders is movably connected to a movable plate, and one side of each movable plate is fixedly connected to a set of movable rods, and each movable rod is connected to the first movable block by a spring.

[0012] By adopting the above technical solution, the design of the movable plate, movable rod, and spring allows one end of the conical filter cartridge to have a certain elasticity. Therefore, when the conical filter cartridge moves the solids in the industrial wastewater, it can not only compress the solids against the inner wall of the conical filter cartridge, but also compress them against the movable plate, which facilitates better separation of the liquid in the solids. Furthermore, after the conveying force of the solids pushes the movable plate to move, the solids can fall between the conical filter cartridge and the movable plate, which facilitates better solid-liquid separation.

[0013] The present invention is further configured such that each of the connecting shafts is provided with a cavity, and each of the connecting shafts is provided with a plurality of slots at the end near the gear.

[0014] By adopting the above technical solution, the cavity and slot design allows industrial wastewater to be transported into the cavity through an external device until the industrial wastewater enters the conical filter cartridge through the slot on the outer surface of the connecting shaft. The solid-liquid separation of industrial wastewater can then be achieved through the conical filter cartridge and its internal structure.

[0015] The present invention is further configured such that a connecting plate is fixedly connected to the surface of the housing, a first motor is mounted on the surface of the connecting plate, and the output end of the first motor is connected to one end of a rotating shaft; a silencer box is fixedly connected to the surface of one of the second movable blocks, a second motor is installed inside the silencer box, and the output end of the second motor is connected to one end of one of the connecting shafts.

[0016] By adopting the above technical solution, the first motor can be started by rotating the connecting rod and the conical filter cylinder around the axis of the rotating shaft, thereby changing the position of the conical filter cylinder. The second motor can be started by driving the other connecting shafts to rotate synchronously through one of the connecting shafts and the gear, so that the spiral blades rotate in the corresponding conical filter cylinders, which can squeeze the industrial wastewater and thus achieve solid-liquid separation.

[0017] The present invention is further configured such that a movable tube that fits into the cavity is slidably connected inside the connecting plate, a fixed plate is fixedly connected to the surface of the movable tube, and the fixed plate and the connecting plate are connected by a telescopic rod.

[0018] By adopting the above technical solution, after the rotating shaft drives the conical filter cylinder to rotate to the designated position via the connecting rod, the fixed plate and the movable tube can be pushed into the cavity of the corresponding connecting shaft by the telescopic rod, thereby conveying industrial wastewater into the cavity. At the same time, after conveying a certain amount of industrial wastewater, the telescopic rod can be activated to drive the movable tube to retract, thereby removing it from the cavity and avoiding affecting the rotation of the connecting shaft.

[0019] The present invention is further configured such that a first discharge port is provided on one side of the box body, and a second discharge port is provided at one end of the box body.

[0020] By adopting the above technical solution, the design of the first and second discharge ports allows the separated solids and liquids to be discharged from their respective discharge ports, facilitating subsequent recycling and processing, thereby improving work efficiency.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention, by conveying industrial wastewater into corresponding conical filter cartridges, drives the connecting shaft and spiral blades to rotate, allowing the liquid in the industrial wastewater to be discharged through the conical filter cartridges, while the solids in the industrial wastewater are conveyed to one end of the conical filter cartridge. Then, by adjusting the position of the conical filter cartridges via the rotating shaft, industrial wastewater can be conveyed into other conical filter cartridges, thus discharging the liquid in the industrial wastewater again. When the spiral blades are conveying solids again, gears can be used to drive other connecting shafts to rotate corresponding spiral blades, thus discharging the solids from other conical filter cartridges. This structure can continuously perform solid-liquid separation of industrial wastewater, improving work efficiency. Furthermore, the cooperation between the connecting shaft and the spiral blades enables solid-liquid separation, improving the quality of wastewater treatment. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A solid-liquid separator for industrial wastewater pretreatment, such as Figure 1-7 As shown, the device includes a housing 1, with a partition 7 fixedly connected inside the housing 1. The partition 7 divides the housing 1 into two spaces for better solid-liquid separation. A first discharge port 20 is provided on one side of the housing 1, and a second discharge port 25 is provided at one end of the housing 1. The first discharge port 20 and the second discharge port 25 are located in different spaces, so the separated solids and liquids can be discharged from their respective discharge ports, facilitating subsequent recycling and processing, thereby improving work efficiency. At the same time, the bottom of each space is designed with a sloping structure, and the lower part of each sloping structure is located at one end of the corresponding first discharge port 20 or second discharge port 25, which facilitates better discharge of solids or liquids.

[0034] Meanwhile, a first movable block 8 is rotatably connected to the surface of the partition 7, and a second movable block 26 is rotatably connected to both ends of the housing 1. This allows the first movable block 8 and the second movable block 26 to rotate on the corresponding surfaces of the partition 7 or the housing 1. Slide grooves 9 are provided on the surface of the partition 7 and both ends of the housing 1. A slider 10 that matches the slide groove 9 is slidably connected in each slide groove 9. Each slider 10 is fixedly connected to the surface of the corresponding first movable block 8 or second movable block 26. Therefore, the stability of the movement of the first movable block 8 or the second movable block 26 is increased by the slide grooves 9 and the sliders 10, which facilitates better use of the separation device.

[0035] A rotating shaft 2 is rotatably connected between a set of second movable blocks 26, and the rotating shaft 2 is rotatably connected to the first movable block 8, so that the rotating shaft 2 can rotate within the first movable block 8 and the second movable block 26. The surface of the rotating shaft 2 is fixedly connected to a conical filter cylinder 4 through multiple sets of connecting rods 3, so that the rotating shaft 2 drives the conical filter cylinder 4 to rotate synchronously through the connecting rods 3, thereby adjusting the position of the conical filter cylinder 4. One end of each conical filter cylinder 4 is rotatably connected to a connecting shaft 5, and the surface of each connecting shaft 5 is fixedly connected to a meshing gear 6. Therefore, when one connecting shaft 5 rotates, the other connecting shafts 5 can be rotated synchronously through the gear 6. The surface of each connecting shaft 5 is provided with a spiral blade 11 that meshes with the inner wall of the conical filter cylinder 4. When the connecting shaft 5 drives the spiral blade 11 to rotate, the conical structure of the conical filter cylinder 4 can squeeze the solids in the sewage. One end of each connecting shaft 5 movably passes through the surface of the first movable block 8 and one of the second movable blocks 26 and extends to the outside for connection.

[0036] Furthermore, each connecting shaft 5 is provided with a cavity 16, and each connecting shaft 5 is provided with several slots 12 near the end of the gear 6. Industrial wastewater can be transported into the cavity 16, allowing it to enter the interior of the conical filter cylinder 4 through the slots 12 on the surface of the connecting shaft 5, facilitating solid-liquid separation. At the same time, a movable plate 13 is movably connected to one end of each conical filter cylinder 4, and a set of movable rods 14 is fixedly connected to one side of each movable plate 13. Each movable rod 14 is connected to the first movable block 8 by a spring 15. After the industrial wastewater undergoes solid-liquid separation, the solids can exert a pushing force on the movable plate 13, which will then react with the solids, facilitating the separation of liquid within the solids. When the pushing force is too large, the movable plate 13 can be moved, causing the solids to fall through the gap between the movable plate 13 and the conical filter cylinder 4. After falling, the movable plate 13 is reset by the spring 15.

[0037] Therefore, during use, the rotating shaft 2 can be driven to rotate, thereby synchronously adjusting the positions of multiple conical filter cylinders 4 until one of them moves to the inlet position, facilitating the delivery of industrial wastewater into it. Simultaneously, after the industrial wastewater is delivered into the corresponding conical filter cylinder 4, the connecting shaft 5 can be driven to rotate, causing the spiral blade 11 to rotate against the inner wall of the conical filter cylinder 4. This allows the liquid in the industrial wastewater to be discharged through the filter holes on the surface of the conical filter cylinder 4, while the solids in the industrial wastewater are delivered to one end of the conical filter cylinder 4. Then, the rotating shaft 2 can be used to adjust the position of the conical filter cylinder 4. The position allows another conical filter cartridge 4 to reach the inlet position, and then the industrial wastewater can be separated into solids and liquids through the connecting shaft 5 and the spiral blade 11. At this time, when the connecting shaft 5 drives the spiral blade 11 to rotate to realize the conveying of solids, the gear 6 can make other connecting shafts 5 drive the corresponding spiral blades 11 to rotate, so that the solids in other conical filter cartridges 4 can be discharged. This structure can continuously separate solids and liquids in industrial wastewater, which can improve working efficiency. Moreover, the cooperation between the connecting shaft 5 and the spiral blade 11 can realize solid-liquid separation, which can improve the quality of wastewater treatment.

[0038] In this embodiment, a connecting plate 22 is fixedly connected to the surface of the housing 1. A first motor 21 is installed on the surface of the connecting plate 22, and the output end of the first motor 21 is connected to one end of the rotating shaft 2. Therefore, the first motor 21 can drive the rotating shaft 2 to rotate, so that the connecting rod 3 and the conical filter cylinder 4 rotate around the axis of the rotating shaft 2, thereby changing the position of the conical filter cylinder 4. A silencer box 24 is fixedly connected to the surface of one of the second movable blocks 26. A second motor 23 is installed inside the silencer box 24, and the output end of the second motor 23 is connected to one end of one of the connecting shafts 5. Therefore, the second motor 23 can drive the connecting shaft 5 to rotate, so that the spiral blade 11 rotates in the corresponding conical filter cylinder 4, which can squeeze the industrial wastewater, thereby achieving solid-liquid separation. At the same time, an electric slip ring concentric with the first movable block 8 is provided at the end of the housing 1 near the second motor 23. The second motor 23 is connected to a brush that cooperates with the electric slip ring, so that the power supply of the second motor 23 can be realized.

[0039] Meanwhile, a movable tube 17 that fits into the cavity 16 is slidably connected inside the connecting plate 22. A fixed plate 18 is fixedly connected to the surface of the movable tube 17, and the fixed plate 18 and the connecting plate 22 are connected by a telescopic rod 19. Therefore, after the rotating shaft 2 drives the conical filter cylinder 4 to rotate to the designated position through the connecting rod 3, the fixed plate 18 and the movable tube 17 can be pushed into the cavity 16 inside the corresponding connecting shaft 5 by the telescopic rod 19, thereby conveying industrial wastewater into the cavity 16. After conveying a certain amount of industrial wastewater, the telescopic rod 19 can be activated to drive the movable tube 17 to retract, thereby withdrawing it from the cavity 16 to avoid affecting the rotation of the connecting shaft 5. A rubber layer is provided at the connection between the movable tube 17 and the cavity 16 to increase the sealing of the connection.

[0040] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
