Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically a solid-liquid separation device for sludge in a sedimentation tank of a waterworks. Background Technology

[0002] Solid-liquid separation equipment for sludge in sedimentation tanks of water treatment plants is a key auxiliary device for ensuring the stable operation of drinking water treatment processes and is widely used in the sludge treatment stage of water supply treatment. During the water purification process, after sedimentation tanks remove suspended particles from the water through gravity settling, a large amount of sludge with high water content is generated. Direct discharge of this sludge can cause pipe blockage, environmental pollution, or water waste. The application of solid-liquid separation equipment achieves efficient separation of water and solid matter in the sludge, creating the necessary conditions for subsequent sludge disposal (such as dewatering, drying, or resource utilization). From an industry demand perspective, with the acceleration of urbanization and the improvement of drinking water standards, the scale of water treatment plants is constantly expanding, and the amount of sludge discharged from sedimentation tanks is increasing significantly, placing higher demands on the treatment efficiency, stability, and adaptability of solid-liquid separation equipment. Efficient operation of the equipment not only reduces the water content of the sludge, reducing transportation and disposal costs, but also avoids sludge backflow interfering with the sedimentation process, ensuring the safety of the treated water. Currently, this equipment is gradually developing towards intelligence and energy conservation. Some advanced equipment further reduces energy and chemical consumption by optimizing operating parameters, aligning with the green and low-carbon industry development trend. As a crucial link in the water treatment process chain, technological advancements in solid-liquid separation equipment have provided reliable support for the efficient operation and environmental compliance of waterworks.

[0003] Existing sludge solid-liquid separation equipment in waterworks sedimentation tanks has revealed insufficient sealing performance during actual operation. Leaks frequently occur at the connection between the equipment cover and the tank body due to sealing failure. This poor sealing not only causes sludge slurry to overflow during the treatment process, polluting the working environment, but may also allow air to enter, affecting the efficiency and quality of sludge solid-liquid separation, increasing the frequency of equipment shutdowns for cleaning, and hindering the continuous and stable operation of the sludge treatment system. Utility Model Content

[0004] The purpose of this utility model is to provide a solid-liquid separation device for sludge in sedimentation tanks of waterworks, which solves the problem of poor sealing between the cover and the tank body during use, which easily leads to leakage at the connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for sludge in a sedimentation tank of a waterworks, comprising a tank body, a base fixedly connected to the lower end of the tank body, a cover in contact with the upper end of the tank body, an inlet pipe fixedly connected to the upper end of the cover, a gasket fixedly connected inside the tank body, a sealing gasket slidably connected inside the cover, a guide rod fixedly connected to the lower end of the cover, a guide block fixedly connected to the outer side of the guide rod, the guide rod slidably connected to the sealing gasket, the guide block slidably connected to the sealing gasket, a limiting frame fixedly connected inside the sealing gasket, the limiting frame contacting the guide rod, the limiting frame slidably connected to the guide block, a spring provided inside the limiting frame, and a fixing mechanism provided on the tank body.

[0006] Preferably, the sealing gasket is slidably connected to the can body, and the sealing gasket is in contact with the gasket ring. The design of the sealing gasket can increase the sealing performance between the lid and the can body.

[0007] Preferably, one end of the spring contacts the limiting frame, and the other end of the spring contacts the sealing gasket. Through the design of the spring, the sealing gasket can be driven to fit with the gasket ring.

[0008] Preferably, the fixing mechanism includes a fixing seat, a fixing seat fixedly connected to the outer side of the can body, a connecting seat fixedly connected to the outer side of the lid, the fixing seat contacting the connecting seat, a slider slidably connected inside the fixing seat, a connecting block fixedly connected to the upper end of the slider, the connecting block slidably connected to the connecting seat, a locking block fixedly connected to the upper end of the connecting block, a locking groove opened inside the connecting seat, a threaded rod rotatably connected inside the fixing seat, a retaining ring fixedly connected to the outer side of the threaded rod, and the retaining ring contacting the inner wall of the fixing seat. Through the design of the fixing mechanism, the lid and the can body can be stably installed.

[0009] Preferably, the locking block contacts the fixed base, and the locking block is slidably connected to the locking slot. The design of the locking block can limit the position of the connecting base.

[0010] Preferably, the outer side of the threaded rod is provided with positive and negative threads, and the threaded rod is connected to the slider by threads. Through the design of the threaded rod, two sliders can be moved simultaneously.

[0011] Preferably, a knob is fixedly connected to the end of the threaded rod away from the fixed seat. The knob contacts the fixed seat, and the design of the knob allows the threaded rod to be rotated easily.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a gasket, a sealing gasket, and a spring to form a sealing structure. The spring force makes the sealing gasket fit tightly against the gasket, which enhances the sealing performance at the connection between the cover and the tank. This design effectively solves the problem of leakage at the connection caused by poor sealing in existing sludge solid-liquid separation equipment, avoids slurry overflow and air mixing, and improves the stability and safety of equipment operation.

[0014] 2. This utility model uses a slider, a locking block, and a threaded rod to form a limiting mechanism. Rotating the threaded rod drives the slider to move the locking block, achieving precise locking with the connecting seat, thereby securing the cover. This design makes the cover and tank more firmly installed, effectively solving the problem of loose connection caused by insecure fixing in traditional equipment, and improving the structural stability of the sludge solid-liquid separation equipment during operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A solid-liquid separation device for sludge in a sedimentation tank of a waterworks includes a tank 1, a base 11 fixedly connected to the lower end of the tank 1, a cover 2 in contact with the upper end of the tank 1, an inlet pipe 21 fixedly connected to the upper end of the cover 2, a gasket 3 fixedly connected inside the tank 1, a sealing gasket 31 slidably connected inside the cover 2, the sealing gasket 31 slidably connected to the tank 1, and the sealing gasket 31 in contact with the gasket 3. The design of the sealing gasket 31 can increase the sealing between the cover 2 and the tank 1. A guide rod 32 is fixedly connected to the lower end of the cover 2.

[0023] Please see Figure 2-5 A guide block 33 is fixedly connected to the outside of the guide rod 32. The guide rod 32 is slidably connected to the sealing gasket 31. The guide block 33 is slidably connected to the sealing gasket 31. A limit frame 34 is fixedly connected inside the sealing gasket 31. The limit frame 34 is in contact with the guide rod 32. The limit frame 34 is slidably connected to the guide block 33. A spring 35 is provided inside the limit frame 34. One end of the spring 35 is in contact with the limit frame 34. The other end of the spring 35 is in contact with the sealing gasket 31. Through the design of the spring 35, the sealing gasket 31 can be driven to fit with the gasket ring 3. A fixing mechanism 4 is provided on the tank body 1.

[0024] Please see Figure 2-5 The fixing mechanism 4 includes a fixing seat 41. The fixing seat 41 is fixedly connected to the outside of the tank body 1, and the connecting seat 42 is fixedly connected to the outside of the cover 2. The fixing seat 41 and the connecting seat 42 are in contact. The fixing seat 41 is slidably connected to the inside of the fixing seat 41. The upper end of the sliding block 43 is fixedly connected to the connecting block 44. The connecting block 44 is slidably connected to the connecting seat 42. The upper end of the connecting block 44 is fixedly connected to the locking block 45. The connecting seat 42 has a locking groove 46 inside. The locking block 45 is in contact with the fixing seat 41 and is slidably connected to the locking groove 46. Through the design of the locking block 45, the connecting seat 42 can be limited.

[0025] Please see Figure 2-5 The fixed base 41 is internally rotatably connected to a threaded rod 47. The outer side of the threaded rod 47 is provided with positive and negative threads. The threaded rod 47 is threadedly connected to the slider 43. Through the design of the threaded rod 47, two sliders 43 can be moved simultaneously. A retaining ring 48 is fixedly connected to the outer side of the threaded rod 47. The retaining ring 48 contacts the inner wall of the fixed base 41. A knob 49 is fixedly connected to the end of the threaded rod 47 away from the fixed base 41. The knob 49 contacts the fixed base 41. Through the design of the knob 49, the threaded rod 47 can be easily rotated. Through the design of the fixing mechanism 4, the lid 2 and the tank 1 can be installed stably.

[0026] The specific implementation process of this utility model is as follows: When in use, by installing the lid 2 and the can body 1, the lid 2 drives the sealing gasket 31 to slide into the can body 1, so that the sealing gasket 31 contacts the gasket ring 3, and the sealing gasket 31 moves on the guide rod 32, so that the sealing gasket 31 compresses the spring 35. The elastic force of the spring 35 can drive the sealing gasket 31 to fit with the gasket ring 3, thereby effectively increasing the sealing between the lid 2 and the can body 1.

[0027] When installing the lid 2 and the tank body 1, the lid 2 moves the connecting seat 42 on the locking block 45, causing the locking block 45 to slide into the locking groove 46 on the connecting seat 42. Then, the knob 49 is turned, causing the knob 49 to rotate the threaded rod 47, causing the threaded rod 47 and the slider 43 to move in a threaded motion. This causes the slider 43 to move on the threaded rod 47, which in turn moves the connecting block 44, causing the connecting block 44 to move the locking block 45, thus locking the locking block 45 with the connecting seat 42. This can limit the position of the lid 2, thus ensuring the lid 2 remains stable after installation with the tank body 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
