Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a solid-liquid separation centrifuge for wastewater treatment. Background Technology

[0002] In the fields of environmental protection and water resource treatment, solid-liquid separation is an important part of the wastewater treatment process, aiming to remove solid particles from wastewater to purify water quality. Centrifuges, as a highly efficient solid-liquid separation device, are widely used in various wastewater treatment scenarios. Their working principle is based on the action of centrifugal force. Through the high-speed rotating separation cylinder, solid particles in the wastewater are thrown against the cylinder wall due to centrifugal force, thereby achieving effective solid-liquid separation.

[0003] During centrifuge operation, water is continuously injected into the separation cylinder through water pipes. This water is then sprayed into the separation screen cylinder through nozzles to assist the separation process. However, the nozzles are usually fixed in a specific position, resulting in some areas of the separation screen cylinder being directly washed by water during the spraying process, while other areas may be left unwashed due to insufficient water flow. This uneven water flow distribution causes areas in frequent contact with water to be continuously washed, easily leading to blockage of the separation screen cylinder. This not only reduces separation efficiency but may also damage the equipment and increase maintenance costs. At the same time, the unwashed areas lack effective water flow, resulting in a significant reduction in the removal of solid particles, affecting the overall solid-liquid separation quality, and indicating that the separation cylinder is not being utilized comprehensively and evenly. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a solid-liquid separation centrifuge for sewage treatment, so as to solve the technical problem that the nozzles are usually fixed in a specific position.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A solid-liquid separation centrifuge for wastewater treatment includes a separation cylinder and three legs welded to the bottom of the separation cylinder. A cylinder cover is provided at the opening at the top of the separation cylinder. A mesh cylinder is rotatably provided inside the separation cylinder, and a filter cloth is installed on the outer surface of the mesh cylinder.

[0008] A water inlet pipe is installed through one side of the top of the cylinder cover. A hose is fixedly connected to the outlet end of the water inlet pipe. A spray pipe is fixedly connected to the outlet end of the hose. A nozzle is installed at the outlet of the spray pipe facing the mesh cylinder. A reciprocating drive source is fixed to the top of the cylinder cover. The movable end of the reciprocating drive source is located inside the separation cylinder and is fixedly connected to the spray pipe.

[0009] As an improved technical solution, a storage cylinder is rotatably installed at the center of the bottom of the inner wall of the separation cylinder via a rotating shaft, and a mesh cylinder is detachably installed inside the storage cylinder. A support plate is welded between the three legs, and a drive motor for driving the electric telescopic rod to rotate is fixed at the center of the top of the support plate. A through groove is formed around the periphery of the drive motor.

[0010] As an improved technical solution, a fixing block is detachably installed between the top of the storage cylinder and the top of the mesh cylinder by bolts.

[0011] As an improved technical solution, the reciprocating drive source includes a pipe frame fixed on the spray pipe, a connecting strip fixed on the side of the pipe frame away from the spray pipe, a rack welded to the top of the connecting strip, and an opening for the rack to enter and exit the top of the cylinder cover. The reciprocating drive source also includes a servo motor mounted on the cylinder cover, and a gear meshing with the rack is mounted on the drive end of the servo motor.

[0012] As an improved technical solution, a guide rod is welded to the top of the inner wall of the cylinder cover and directly above the pipe rack, and a sliding hole is opened on the top of the pipe rack to slide with the guide rod.

[0013] As an improved technical solution, transverse connecting blocks are welded to both sides of the cylinder cover, and electric telescopic rods are fixed on the convex edges on both sides of the support plate, with the movable end of the electric telescopic rod connected to the bottom of the transverse connecting block.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the cylinder cover and the separating cylinder are separated and merged by the extension and retraction of the electric telescopic rod. The cylinder cover is opened by the electric telescopic rod to facilitate the installation and disassembly of the mesh cylinder. At the same time, the fixing block is fixed between the mesh cylinder and the fixing block by bolts, which further facilitates the installation, disassembly and replacement of the mesh cylinder.

[0016] 2. In this utility model, while the nozzle is spraying water onto the mesh cylinder, the servo motor drives the gear to rotate. Under the meshing transmission of the gear and rack, the rack is driven to move upward, which in turn drives the spray pipe to move downward through the connecting plate and the pipe frame. This causes the nozzle to move downward vertically along the mesh cylinder. Subsequently, the servo motor drives the gear to rotate in the opposite direction. Under the meshing transmission of the gear and rack, the nozzle is driven to move upward. Therefore, the nozzle is in an active state when spraying water, thus expanding the spray range of the nozzle.

[0017] 3. This utility model expands the utilization rate of the mesh cylinder and the amount of water sprayed at the same time by using multiple nozzles to spray water out of the inlet pipe, which helps to improve the separation efficiency. At the same time, when the nozzles are spraying water, the reciprocating drive source can drive the nozzles to move vertically and reciprocally, so that the nozzles move up and down along the vertical of the mesh cylinder, further expanding the spray range of the nozzles on the mesh cylinder. Simultaneously, the drive motor drives the mesh cylinder to rotate, so that the nozzles can spray the mesh cylinder 360 degrees without dead angles, so that the mesh cylinder can fully and evenly contact the wastewater, improving the separation effect.

[0028] like Figures 1 to 3 As shown in the figure, this embodiment provides a solid-liquid separation centrifuge for sewage treatment. This solid-liquid separation centrifuge for sewage treatment includes a separation cylinder 1 and three support legs 11 welded to the bottom of the separation cylinder 1. A water outlet pipe is welded to the water outlet end of the separation cylinder 1. A cylinder cover 15 is provided at the open end of the top of the separation cylinder 1. A mesh cylinder 2 is rotatably provided inside the separation cylinder 1. A filter cloth 21 is installed on the outer surface of the mesh cylinder 2.

[0029] A water inlet pipe 3 is installed through one side of the top of the cylinder cover 15. A hose 31 is fixedly connected to the outlet end of the water inlet pipe 3. A spray pipe 32 is fixedly connected to the outlet end of the hose 31. A nozzle 33 is installed at the outlet of the spray pipe 32 facing the mesh cylinder 2. A reciprocating drive source 4 is fixedly installed on the top of the cylinder cover 15. The movable end of the reciprocating drive source 4 is located inside the separation cylinder 1 and is fixedly connected to the spray pipe 32.

[0030] By spraying water from multiple nozzles 33 onto the inlet pipe 3, the utilization rate of the mesh cylinder 2 and the amount of water sprayed at the same time are increased, which helps to improve the separation efficiency. At the same time, when the nozzles 33 are spraying water, the reciprocating drive source 4 can drive the nozzles 33 to move vertically and reciprocally, so that the nozzles 33 move vertically along the mesh cylinder 2, further expanding the spray range of the nozzles 33 on the mesh cylinder 2. Simultaneously, the drive motor 24 drives the mesh cylinder 2 to rotate, so that the nozzles 33 can spray the mesh cylinder 2 360 degrees without dead angles, so that the mesh cylinder 2 can fully and evenly contact the wastewater, improving the separation effect.

[0031] like Figures 1 to 2 As shown in the figure, in this embodiment, a storage cylinder 23 is rotatably installed at the center of the bottom of the inner wall of the separation cylinder 1 via a rotating shaft, and the mesh cylinder 2 is detachably installed inside the storage cylinder 23. A support plate 12 is welded between the three legs 11, and a drive motor 24 for driving the electric telescopic rod 13 to rotate is fixed at the center of the top of the support plate 12. The drive end of the drive motor 24 is connected to the rotating shaft end of the storage cylinder 23, and a through groove 25 is formed around the periphery of the drive motor 24.

[0032] like Figure 2 As shown, in this embodiment, a fixing block 22 is detachably installed between the top of the storage cylinder 23 and the top of the mesh cylinder 2 by bolts. The fixing block 22 is fixed between the mesh cylinder 2 and the fixing block 22 by bolts, which further facilitates the assembly, disassembly and replacement of the mesh cylinder 2.

[0033] like Figures 1 to 3 As shown in the figure, in this embodiment, the reciprocating drive source 4 includes a pipe frame 45 fixed on the spray pipe 32. A connecting strip 44 is fixed on the side of the pipe frame 45 away from the spray pipe 32. A rack 43 is welded to the top of the connecting strip 44, and the top of the cylinder cover 15 has an opening for the rack 43 to enter and exit. The reciprocating drive source 4 also includes a servo motor 41 installed on the cylinder cover 15. A gear 42 that meshes with the rack 43 is installed on the drive end of the servo motor 41. While the nozzle 33 sprays water onto the mesh cylinder 2, the servo motor 41... 1. Drive gear 42 to rotate. Under the meshing transmission of gear 42 and rack 43, drive rack 43 to move upward. Then, through connecting plate 44 and pipe frame 45, drive spray pipe 32 to move downward, so that nozzle 33 moves downward vertically along mesh cylinder 2. Subsequently, servo motor 41 drives gear 42 to rotate in the opposite direction. Under the meshing transmission of gear 42 and rack 43, drive nozzle 33 to move upward. Therefore, when nozzle 33 sprays water, it is in an active state, expanding the spray range of nozzle 33.

[0034] like Figures 2 to 3As shown in the figure, in this embodiment, a guide rod 46 is welded to the top of the inner wall of the cylinder cover 15 and directly above the tube frame 45, and a sliding hole is opened on the top of the tube frame 45 to slide with the guide rod 46.

[0035] like Figure 1 As shown, in this embodiment, horizontal connecting blocks 14 are welded to both sides of the cylinder cover 15, and electric telescopic rods 13 are fixed on the protruding edges on both sides of the support plate 12. The movable end of the electric telescopic rod 13 is connected to the bottom of the horizontal connecting block 14. The cylinder cover 15 and the separation cylinder 1 are separated and merged by the extension and retraction of the electric telescopic rod 13. The cylinder cover 15 is opened by the electric telescopic rod 13 to facilitate the installation and removal of the mesh cylinder 2.

[0036] In use, the electric telescopic rod 13 extends and drives the cylinder cover 15 to move upward through the cross connecting block 14, thereby separating the cylinder cover 15 from the separation cylinder 1 and exposing the inner cavity of the separation cylinder 1. Then, the mesh cylinder 2 is placed inside the storage cylinder 23. The connecting block 22 is fixed between the storage cylinder 23 and the top of the filter cloth 21 by bolts, fixing the mesh cylinder 2 inside the storage cylinder 23. After installation, the electric telescopic rod 13 shortens and the cylinder cover 15 is put back on the top of the separation cylinder 1. The nozzle 33 will also enter the inner cavity of the mesh cylinder 2.

[0037] Wastewater is injected into the inlet pipe 3. The wastewater enters the spray pipe 32 through the hose 31 and is finally sprayed onto the mesh cylinder 2 through the nozzle 33. Solid impurities in the waste liquid are filtered by the mesh cylinder 2 and the filter cloth 21. Water passes directly through and enters the interior of the filter cloth 21 and is finally discharged through the outlet pipe.

[0038] While the nozzle 33 sprays water onto the mesh cylinder 2, the drive motor 24 drives the storage cylinder 23 to rotate at high speed, which in turn drives the mesh cylinder 2 to rotate at high speed. Under the action of centrifugal force, the water inside the mesh cylinder 2 is further thrown outward, thereby achieving solid-liquid separation of the waste liquid.

[0039] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
