Description

Technical Field

[0001] The present invention relates to the technical field of sludge pumps, and in particular to a sludge pump for sewage treatment. Background Art

[0002] A sludge pump is a mechanical device used to extract and transport sludge, which can transport the sludge in treatment units such as sedimentation tanks and thickening tanks to subsequent treatment links, such as sludge dewatering equipment, sludge digestion tanks, etc., to ensure the smooth progress of the sludge treatment process. At the same time, the discharge and treatment of sludge generated in some industrial production processes also rely on the function of sludge pumps.

[0003] According to the characteristics of sludge and application scenarios, there are many types of sludge pumps, mainly including the following: 1. Vertical sludge pump, which is usually installed at the bottom of the tank and is suitable for transporting sludge at the bottom of sedimentation tanks, ponds, etc. The vertical sludge pump does not occupy floor space and has a compact structure, and can effectively handle the sludge transportation task with large flow and low head. Its design is generally vertical, which can reduce the loss of the power transmission system.

[0004] 2. Horizontal sludge pump, which is generally used to transport sludge with high viscosity and high solid content. Its design is suitable for the situation where the sludge contains more solid particles or sediment, and is often used to handle relatively thick sludge. The advantage of the horizontal sludge pump lies in its high stability and reliability, and it is suitable for applications that require large power and pressure.

[0005] 3. Pneumatic diaphragm pump, which is powered by an air compressor and is suitable for transporting sludge with high viscosity and high solid content. One feature of the pneumatic diaphragm pump is that it does not require electric drive and is suitable for use in special places such as explosion-proof areas, especially suitable for irregularly shaped sludge particles or sludge containing foreign objects.

[0006] The prior art document with the publication number of CN116085268A provides a sludge pump for sewage treatment. By separating the sludge into mud and water, it is convenient to separately crush the mud blocks and hard garbage in the sludge. A large amount of separated thin mud is transported through the annular space, and the thin mud does not pass through the square cavity used as the crushing space. Compared with the method of directly crushing the whole sludge without mud-water separation, this solution improves the transportation efficiency of the sludge.

[0007] When the prior art sludge pump is in use, it realizes the crushing and transportation of sludge. However, when extracting and treating sludge in park lakes, the sludge pump is not convenient to be installed and fixed on a ship for use, resulting in limited treatment scope and affected overall working efficiency.

[0008] In summary, in the prior art, there is a lack of technology for sludge pumps that are convenient to install on ships. Summary of the Invention

Detailed implementation manners

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] As Figures 1-8 shown, a sludge pump for sewage treatment includes a mounting frame 1. A hull 2 is arranged in the middle of the mounting frame 1. A mounting mechanism 3 is arranged on the mounting frame 1. A pump cover 4 is fixedly connected to the lower side of the mounting frame 1. A sludge pump 5 is installed in the pump cover 4. A mud guide seat 6 is fixedly connected to the mounting frame 1. A swing pipe 7 is rotatably connected to the outer wall of one side of the pump cover 4. An adjusting pipe 8 is slidably fitted to the outer wall of the swing pipe 7. Floating seats 9 are slidably fitted to both sides of the mounting frame 1. The sludge pump 5 is a self-priming sludge pump 5. When it starts to work, negative pressure will be generated inside the pump, the air will be discharged, and the pump will be filled with liquid. During the liquid suction process, the sludge pump 5 enables the liquid and solid mixture to smoothly enter the pump body through its special impeller design.

[0024] As Figure 3 shown, a handle 101 is fixedly connected to the middle of the upper end of the mounting frame 1. Universal joints 102 are rotatably connected to both sides of the bottom end of the mounting frame 1. A handrail 103 is fixedly connected to the outer end of the universal joint 102. Two limiting strips 108 are fixedly connected to both sides of the mounting frame 1 in a symmetric structure.

[0025] The inner end of the universal joint 102 is fixedly connected with a worm 104. On both sides of the worm 104, worm wheels 105 are meshed and driven. On the worm wheels 105, adjustable support legs 106 are fixedly connected. The other end of the adjustable support leg 106 is rotatably connected with a moving wheel 107. The moving wheels 107 installed on the adjustable support legs 106 enable the whole device to move conveniently on the ground. Especially when the device needs to be moved or adjusted in position, this design greatly reduces the complexity of manual handling. The moving wheels 107 provide low friction, enabling the device to move easily on different ground surfaces, improving the operability of the device. The adjustable support legs 106 are designed to be retractable. When the device is in water, by retracting the adjustable support legs 106, it can effectively avoid the contact between the adjustable support legs 106 and underwater objects (such as rocks, sediments, obstacles, etc.). It avoids the collision between the adjustable support legs 106 and the bottom objects in water, reduces the risk of equipment damage, and improves the safety and durability of the equipment.

[0026] As Figure 4 As shown, the installation mechanism 3 includes a grip rod 301. At both ends of the grip rod 301, hinge seats 302 are fixedly connected. On the hinge seats 302, two connecting rods 303 are symmetrically rotatably connected. The other end of the connecting rod 303 is rotatably connected with a limit rod 304. The limit rod 304 is slidably matched with the mounting frame 1. At the bottom end of the limit rod 304, an inclined surface 305 is provided. On one side of the limit rod 304, a tension spring 306 is fixedly connected. The other end of the tension spring 306 is fixedly connected with the mounting frame 1. The bottom end of the limit rod 304 is in movable contact with the transverse rib of the hull 2.

[0027] By arranging the installation mechanism 3 on the mounting frame 1 of the sludge pump 5, the device can be installed on the transverse rib of the hull 2, which can significantly enhance the stability of the equipment, expand the operation range and improve the operation efficiency, providing greater flexibility and adaptability for the sludge pump 5, enabling it to efficiently suck sludge under different water conditions, while reducing energy waste and operation difficulty, and being applicable to different scales of operation requirements.

[0028] As Figure 5 As shown, on the mud guiding seat 6, two mud guiding pipes 601 are symmetrically fixedly connected. The end of the mud guiding pipe 601 above the mounting frame 1 is arranged in an inclined structure. The mud guiding seat 6 is fixedly connected with the output end of the sludge pump 5. The inclined structure at the top end of the mud guiding pipe 601 enables the sludge to accurately flow to the lower sludge seat 903, avoiding the situation of sludge overflow or deviation from the target area.

[0029] As Figure 6As shown in the figure, one end of the swing pipe 7 is rotatably connected to the input end of the sludge pump 5. One end of the swing pipe 7 is fixedly connected with an adjusting wheel 701. A rack 702 is meshed and driven on one side of the adjusting wheel 701. One end of the rack 702 is fixedly connected with an electric push rod 703. The electric push rod 703 is fixedly connected with the inner wall of the pump cover 4.

[0030] As Figure 7 As shown in the figure, one end of the adjusting pipe 8 is fixedly connected with a spherical net head 801. A threaded rod 802 is threadedly connected to one side of the adjusting pipe 8. One end of the threaded rod 802 is rotatably connected with a motor cover 803. The motor cover 803 is fixedly connected with the swing pipe 7. A motor 804 is fixedly connected inside the motor cover 803. The output end of the motor 804 is fixedly connected with the threaded rod 802. The spherical net head 801 can effectively prevent sludge particles or sundries from entering the suction pipeline. The mesh holes of the spherical net head 801 can filter larger particles, reduce the risk of pipeline blockage, improve the suction efficiency and the service life of the pipeline. The shape of the spherical net head 801 can make the suction force evenly distributed on the entire surface of the net head. In this way, the suction process is more balanced, which helps to suck the sludge at the bottom of the lake more comprehensively, avoid only sucking the sludge in a local area, and ensure a more comprehensive suction effect. The shape of the spherical net head 801 can smoothly contact the bottom of the lake, thus reducing the disturbance to the bottom environment of the lake. Compared with a sharp suction head, the spherical net head 801 can better disperse the suction force and avoid damaging the stability of the lake bottom ecology and sediment.

[0031] As Figure 8 As shown in the figure, one side of the floating seat 9 is fixedly connected with a sliding seat 901. The sliding seat 901 is slidably matched with the limiting strip 108. Two air bags 902 are fixedly connected to the outside of the floating seat 9. The air bags 902 are made of PVC polyvinyl chloride material, which has the advantages of corrosion resistance, wear resistance, ultraviolet resistance, high strength and relatively low price. By setting the air bags 902 on the floating seat 9, the weight of the sludge seat 903 can be effectively offset, avoiding the tilting or instability of the ship, improving the overall stability and reducing the risk of capsizing. During the sludge operation, the ship may be disturbed by the sludge seat 903 or the surrounding water area. The air bags 902 can effectively absorb part of the water surface fluctuation or external force, reducing the pressure or imbalance caused to the hull 2 during the sludge operation process.

[0032] A sludge seat 903 is placed inside the floating seat 9, and a hook rack 904 is fixedly connected inside the sludge seat 903. The setting of the hook rack 904 enables the lifting equipment to quickly and stably lift the sludge seat 903. The lifting process can be more efficient, saving time and reducing the operation difficulty. Especially in the working environment where the sludge seat 903 needs to be lifted frequently, by fixedly connecting the hook rack 904 inside the sludge seat 903, the lifting efficiency, safety and accuracy can be greatly improved. This design simplifies the lifting operation, reduces the risk of manual intervention and misoperation, and ensures the safety of the equipment and personnel. At the same time, it can adapt to different types of lifting equipment, optimizes the flexibility of the lifting process, reduces equipment damage, and improves the overall operation efficiency and space utilization.

[0033] Working principle: When it is necessary to treat the sludge in the park lake, first install the device on the hull 2, place the mounting frame 1 on the hull 2, align the upper end of the mounting frame 1 with the transverse rib on the hull 2, and then when the mounting frame 1 moves downward, the inclined surface 305 at the bottom end of the limit rod 304 will contact the transverse rib on the hull 2, enabling the limit rod 304 to move away. Then, under the action of the tension spring 306, the limit rod 304 is driven to reset, so that the mounting frame 1 is installed on the hull 2. When it is necessary to remove the device from the hull 2, by moving the grip 301 upward, the grip 301 drives the hinge seat 302 to move upward. At this time, the hinge seat 302 drives the connecting rod 303, so that the connecting rod 303 drives the limit rod 304 to move outward, releasing the limit on the transverse rib on the hull 2, and the mounting frame 1 can be removed. After the mounting frame 1 is installed on the hull 2, by rotating the universal joint 102 connected to the handle 103, the universal joint 102 drives the connected worm 104 to rotate, so that the worm 104 can drive the engaged worm gear 105 to rotate, and the worm gear 105 can drive the connected adjustable support leg 106 to rotate upward and retract, thus reducing the obstruction during the movement of the hull 2. Before removing the device from the hull 2, by lowering the adjustable support leg 106, the moving wheels 107 are used to facilitate the movement of the device on the ground. When installing the device on the hull 2, the airbag 902 on the floating seat 9 will cause the floating seat 9 to float on the water surface. Then, when sucking and treating the sludge at the bottom of the lake, the electric push rod 703 is used to drive the connected rack 702 to move, so that the rack 702 drives the swing pipe 7 connected to the adjusting wheel 701 to be adjusted to an appropriate angle. Then, the motor 804 is used to drive the connected threaded rod 802 to rotate, so that the threaded rod 802 can drive the adjusting pipe 8 to move out, and the spherical mesh head 801 on the adjusting pipe 8 is placed in the sludge. Then, under the action of the sludge pump 5, the sludge will be filtered through the spherical mesh head 801 and injected into the mud guide seat 6 through the adjusting pipe 8 and the swing pipe 7, and then sprayed out through the mud guide pipe 601 on the mud guide seat 6 and collected in the sludge seat 903. When the sludge seat 903 is full of sludge, the hook of the lifting device is hung on the hook rack 904, and the sludge seat 903 can be taken out of the floating seat 9 for cleaning.
