Description

Technical Field

[0001] This utility model relates to the field of cyclone sedimentation sand separators, specifically to a cyclone sedimentation sand separator that is easy to maintain. Background Technology

[0002] A vortex grit chamber is a physical grit removal device that uses mechanical force to control the flow pattern and velocity of water. It accelerates the sedimentation of sand particles and separates organic matter through centrifugal force. The core structure includes an inlet, a sedimentation zone, a grit hopper, a turbine drive device, and a grit discharge system. After sewage enters tangentially, it forms a vortex. Under the action of centrifugal force, sand particles settle along the pool wall into the grit hopper, while organic matter is discharged with the central water flow. It has the advantages of high-efficiency grit removal, small footprint, and adaptability to flow rate changes. It is widely used in urban sewage treatment and industrial wastewater pretreatment. The vortex grit chamber sand-water separator is its supporting equipment, used to separate the sand-water mixture discharged from the grit chamber. The typical structure is a spiral sand-water separator, which consists of a shaftless spiral, a U-shaped trough, a water tank, a guide plate, and a drive device. After the sand-water mixture enters, the sand particles are deposited at the bottom of the trough. The two work together to achieve effective separation of sand particles and water, improving sewage treatment efficiency.

[0003] Existing cyclone grit chambers and sand separators lack easy maintenance capabilities during use. This makes it difficult to disassemble and maintain the integrated cyclone grit chamber and sand separator. The lack of regular maintenance will also lead to accelerated wear of components, affecting sewage treatment efficiency. Moreover, long-term use will reduce separation efficiency and increase sand residue, affecting subsequent treatment processes.

[0004] Therefore, it is necessary to invent a vortex grit chamber sand-water separator that is easy to maintain in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cyclone grit chamber sand-water separator that is easy to maintain. This is achieved through a main separator body, a first flange, a first conical guide tube, a first inner sealing ring, a second flange, a second conical guide tube, and a sedimentation tank. This design, using flange connections, allows for quick installation and disassembly, significantly reducing maintenance time and costs. Furthermore, the inner sealing ring and the inclined guide vanes work together to reduce leakage risks. Simultaneously, the inclined guide vanes guide the water flow to form a spiral flow field, enhancing the centrifugal separation effect. This addresses the lack of ease of maintenance in existing technologies, which often result in integrated cyclone grit chamber sand-water separators that are difficult to disassemble and maintain. Lack of regular maintenance can also lead to accelerated component wear, affecting wastewater treatment efficiency. Moreover, long-term use can reduce separation efficiency, increase sand residue, and negatively impact subsequent treatment processes.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The cyclone grit chamber sand-water separator shown includes a main separator body 1, which is the main body for sand-water separation in the cyclone grit chamber.

[0026] The first flange 5 is fixedly installed on the lower exterior of the main separator body 1 for assembling the sand-water separator. The upper part of the first flange 5 is threaded with a first double-ended bolt 6. The bottom end of the first double-ended bolt 6 is threadedly connected to a first conical guide tube 7. The upper interior of the first conical guide tube 7 is fixedly installed with a first inner sealing ring 8. The interior of the first inner sealing ring 8 is fixedly installed with inclined guide vanes 9.

[0027] The second flange 10 is fixedly installed on the lower exterior of the first conical guide tube 7 for guide tube assembly. A second double-ended bolt 11 is threaded through the upper part of the second flange 10. The bottom end of the second double-ended bolt 11 is threadedly connected to the second conical guide tube 12. A second inner sealing ring 13 is fixedly installed inside the upper part of the second conical guide tube 12. A sedimentation tank 14 is threadedly connected to the bottom end of the second conical guide tube 12. An inner annular groove 15 is formed on the upper part of the main separator body 1. An inner slider 16 is slidably connected inside the inner annular groove 15. Above the inner slider 16... An inner auxiliary flow frame 17 is fixedly installed, and a main flow vane 18 is fixedly installed inside the inner auxiliary flow frame 17. External teeth 19 are fixedly installed on the outside of the inner auxiliary flow frame 17. The main separator body 1, the first cone guide cylinder 7 and the second cone guide cylinder 12 are connected by a first flange 5 and a second flange 10. At the entire connection, a first inner sealing ring 8 and a second inner sealing ring 13 are inserted inside the first cone guide cylinder 7 and the second cone guide cylinder 12. At the same time, inclined guide vanes 9 are also provided inside the first inner sealing ring 8 and the second inner sealing ring 13.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, an external support frame 2 is fixedly installed on the outside of the main separator body 1. An inlet 3 is opened on one side of the outside of the main separator body 1, and an outlet 4 is opened on the other side of the outside of the main separator body 1. The high and low distribution of the inlet 3 and outlet 4 allows wastewater to flow into the pretreatment zone from the top, and grease to float naturally, reducing the damage of turbulence to the separation layer. The number of inclined guide vanes 9 is set to multiple, and the multiple inclined guide vanes 9 are distributed in a ring array on the first inner sealing ring 8. The inclined guide vanes 9 can accelerate the separation of water and sand and improve the centrifugal separation effect. The inclined guide vanes 9 are fixedly installed inside the second inner sealing ring 13 and the first inner sealing ring 8. The first cone guide tube 7 and the second cone guide tube 12 are used together. The first cone guide tube 7 and the second cone guide tube 12 form a multi-stage separation chamber through the difference in taper, realizing multiple turns and centrifugal separation of the fluid.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, a fixing block 20 is fixedly installed on the outside of the main separator body 1. A servo motor 21 is fixedly installed at the bottom of the fixing block 20. A drive gear 22 is fixedly installed at the output end of the servo motor 21. The drive gear 22 meshes with the external gear 19. The meshing and rotation of the drive gear 22 and the external gear 19 can drive the inner auxiliary flow frame 17 inside the main separator body 1 to rotate at a uniform speed, thereby accelerating the separation speed. An outer fixing frame 23 is fixedly installed on the top of the main separator body 1. A drive motor 24 is fixedly installed on the top of the outer fixing frame 23. A centrifugal separation rod 25 is fixedly installed at the output end of the drive motor 24. The centrifugal separation rod 25 is rotatably connected to the main separator body 1. The centrifugal separation rod 25 rotates inside the main separator body 1, thereby pushing the sand and water entering the main separator body 1 to be separated quickly.

[0030] The working principle of this utility model is as follows: First, connect the external power supply and input the wastewater to be separated into the main separator body 1 through the inlet 3. Then, turn on the switch of the drive motor 24 on the outer fixed frame 23, so that the drive motor 24 drives the centrifugal separation rod 25 to rotate rapidly, thereby generating centrifugal force by rotating the wastewater entering the main separator body 1. Next, turn on the switch of the servo motor 21, so that the servo motor 21 drives the drive gear 22 to mesh with the external teeth 19 on the outside of the inner auxiliary flow frame 17, so that the inner auxiliary flow frame 17 rotates and slides above the main separator body 1 by relying on the inner ring groove 15 and the inner slider 16. In this way, the rotating inner auxiliary flow frame 17 can also accelerate the rotation speed of the wastewater through the main flow plate 18, thereby increasing the centrifugal force. Then, the main separator body 1, the first cone guide cylinder 7 and the second cone guide cylinder 12 are connected by the first flange 5 and the second flange 10. Moreover, at the connection, the first inner sealing ring 8 and the second inner sealing ring 13 are inserted inside the first cone guide cylinder 7 and the second cone guide cylinder 12. The inner sealing ring 8 and the second inner sealing ring 13 are also equipped with inclined guide vanes 9. This allows the wastewater to be guided downwards layer by layer by the first conical guide tube 7 and the second conical guide tube 12 after passing through the main separator body 1 due to centrifugal force. The inclined guide vanes 9 also accelerate the separation of water and sand. The sand sinks into the sedimentation tank 14 due to centrifugal rotation, while the separated water flows out through the outlet 4. This design makes the vortex grit chamber sand-water separator easy to maintain. The flange connection allows for quick installation and disassembly, significantly reducing maintenance time and costs. The inner sealing ring and the inclined guide vanes 9 work together to reduce the risk of leakage. Simultaneously, the inclined guide vanes 9 guide the water flow to form a spiral flow field, enhancing the centrifugal separation effect. After completing the installation and use of the vortex grit chamber sand-water separator according to the above operations, turn off the servo motor 21 and the drive motor 24. If not used for a long period, simply disconnect the external power supply. This completes the usage process of the easy-to-maintain vortex grit chamber sand-water separator.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
