[0002] In wastewater treatment and industrial production processes, sedimentation tanks are key equipment for separating suspended solids and liquids. Their sludge discharge efficiency directly affects the stability and treatment effect of the overall process. Traditional sedimentation tank sludge discharge methods mostly adopt bottom sludge discharge structures. Through sludge discharge pipes and valves set at the bottom of the tank, gravity or sludge pumps are used to discharge the sludge deposited at the bottom of the tank. However, in practical applications, some sedimentation tanks cannot adopt the conventional bottom sludge discharge method due to structural design, site limitations, or operating conditions. Some sedimentation tanks have limited bottom space, making it difficult to install sludge discharge equipment. Or, during the renovation of existing facilities, the original foundation structure restricts the large-scale modification of the tank bottom to arrange a sludge discharge system, thus affecting the efficiency of bottom sludge discharge.

A drive rod is fixedly installed on both sides of the top of the sludge scraper. The front end of the drive rod extends through to the outside of the sedimentation tank body and is connected to an electric cylinder through a drive plate. The rear end of the electric cylinder is connected to the front of the sedimentation tank body.

[0007] As a preferred embodiment, a support plate is fixedly installed on the back of the sedimentation tank body, and positioning vertical plates are installed on both sides of the top of the support plate. A support spring is installed on the inner side of the upper end of the positioning vertical plate, and a clamping sleeve is installed on the inner end of the support spring.

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

[0013] 1. This utility model breaks through the dependence of traditional bottom sludge discharge on the sedimentation tank structure, eliminating the need for complex modifications to the tank bottom or the reservation of sludge discharge space. It is especially suitable for sedimentation tanks with limited bottom space, obstacles, or difficult modifications, significantly expanding the application scenarios of the sludge discharge device. By placing the sludge pump above the tank surface and discharging sludge through the upper-extending sludge discharge pipe, the equipment installation process is simplified, construction difficulty and cost are reduced, and the construction cycle is shortened. It is particularly suitable for the renovation and upgrading of existing sedimentation tanks.

It can not only fit the pipe tightly to prevent loosening, but also avoid excessive compression that could damage the pipe. While ensuring the stability of the connection, it improves the compatibility with sludge discharge pipes of different specifications. During the operation of the sedimentation tank, the support spring can effectively buffer the impact of equipment vibration on the sludge discharge pipe, reduce pipe wear and noise caused by vibration. At the same time, the elastic connection method can absorb the impact force generated by the fluid flow in the pipe, reduce the risk of pipe resonance, and ensure the long-term stable operation of the sludge discharge system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1:

[0023] Please see Figure 1 As shown, this utility model provides a sludge removal device for the upper part of a sedimentation tank, including a sedimentation tank body 1. A top plate 2 is fixedly installed on the top of the sedimentation tank body 1. A sludge pump 3 is fixedly installed on the top of the top plate 2. The two ends of the sludge pump 3 are respectively connected to a sludge discharge pipe 6 and a sludge inlet pipe 4. A clamping clamp 5 is sleeved on the outer surface of the sludge inlet pipe 4. A connecting frame 11 is fixedly installed on the outside of the clamping clamp 5. An adjusting bracket 12 is installed on the front of the connecting frame 11. The adjusting bracket 12 is U-shaped and its outer end extends to the outside of the sedimentation tank body 1 and is connected by an adjusting knob 16.

[0024] This technical solution breaks through the reliance on the sedimentation tank structure for traditional bottom sludge discharge, eliminating the need for complex modifications to the tank bottom or the reservation of sludge discharge space. It is particularly suitable for sedimentation tanks with limited bottom space, obstacles, or difficult modifications, significantly expanding the application scenarios of the sludge discharge device. By placing the sludge pump 3 above the tank surface and discharging sludge through the upper-extending sludge discharge pipe 6, the equipment installation process is simplified, construction difficulty and cost are reduced, and the construction cycle is shortened. It is especially suitable for the renovation and upgrading of existing sedimentation tanks. The sludge inlet pipe 4 can precisely extend to the specific part of the sedimentation tank that needs sludge discharge, effectively avoiding dead corners of sludge accumulation, improving sludge discharge efficiency and thoroughness, and ensuring the stable operation and treatment effect of the sedimentation tank.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, a positioning seat 13 is fixedly installed on the front of the sedimentation tank body 1. An adjustment groove 14 is opened on the outside of the positioning seat 13. An adjustment slide plate 15 is slidably connected to the outside of the adjustment groove 14. The front of the adjustment slide plate 15 is connected to the inner side of the front end of the adjustment bracket 12. The locking end of the adjustment knob 16 passes through the adjustment slide plate 15 and is firmly connected to the front of the positioning seat 13. A sludge scraper 17 is provided on the rear side of the inner cavity of the sedimentation tank body 1. A drive rod 18 is fixedly installed on both sides of the top of the sludge scraper 17. The front end of the drive rod 18 passes through to the outside of the sedimentation tank body 1 and is connected to an electric cylinder 19 through a drive plate. The rear end of the electric cylinder 19 is connected to the front of the sedimentation tank body 1.

[0027] Adopting such Figure 1 The technical solution shown, with its combination of positioning seat 13, adjusting groove 14, adjusting slide plate 15, and adjusting knob 16, enables flexible adjustment of the position of the adjusting bracket 12. Through the tight connection between the adjusting knob 16, adjusting slide plate 15, and positioning seat 13, the installation position of the adjusting bracket 12 can be precisely adjusted according to actual usage requirements, allowing the sedimentation tank to adapt to different operating conditions and significantly improving the equipment's versatility and flexibility. The structural design of the scraper 17, drive rod 18, drive plate, and electric cylinder 19 constitutes an automated sludge cleaning system. The electric cylinder 19, connected to the drive rod 18 via the drive plate, drives the scraper 17 to reciprocate within the rear of the sedimentation tank body 1, efficiently removing settled sludge. This automated design reduces manual intervention, improves sludge cleaning efficiency, reduces labor intensity, and ensures the sedimentation tank maintains a consistently good sedimentation effect, thus improving overall operating efficiency.

[0028] Secondly, in the technical solution, a support plate 7 is fixedly installed on the back of the sedimentation tank body 1. Positioning vertical plates 8 are installed on both sides of the top of the support plate 7. A support spring 9 is installed on the inner side of the upper end of the positioning vertical plate 8. A clamping sleeve 10 is installed on the inner end of the support spring 9. The clamping sleeve 10 is clamped on the surface of the outer end of the sludge discharge pipe 6. The sludge inlet pipe 4 is assembled by connecting multiple pipes through a flange. The lower end of the sludge inlet pipe 4 is connected to a trumpet-shaped sludge suction pipe.

[0029] Its adoption is as follows Figure 1 The technical solution shown forms an elastic clamping structure through the combination of support plate 7, positioning vertical plate 8, support spring 9, and clamping sleeve 10. The support spring 9 gives the clamping sleeve 10 adaptive adjustment capability, which can automatically adjust the clamping force according to the slight difference in the outer diameter of the sludge discharge pipe 6. It can not only fit the pipe tightly to prevent loosening, but also avoid excessive compression and damage to the pipe. While ensuring the stability of the connection, it improves the compatibility with sludge discharge pipes 6 of different specifications. During the operation of the sedimentation tank, the support spring 9 can effectively buffer the impact of equipment vibration on the sludge discharge pipe 6, reduce pipe wear and noise caused by vibration. At the same time, the elastic connection method can absorb the impact force generated by the fluid flow in the pipe, reduce the risk of pipe resonance, and ensure the long-term stable operation of the sludge discharge system.

[0030] Example 3:

[0031] This utility model is as follows Figures 1-4 As shown, a guide rod is fixedly installed on the upper part of the clamping sleeve 10, and the outer end of the guide rod extends through to the outside of the positioning vertical plate 8; a rubber pad is installed on the inner wall of the clamping sleeve 10, and the rubber pad is arc-shaped and sleeved on the surface of the end of the sludge discharge pipe 6 and sealed; a vertical guide rod is fixedly installed on the front side of the inner cavity of the sedimentation tank body 1, and an adjustment seat is slidably installed on the outside of the vertical guide rod, and the outside of the adjustment seat is connected to one side of the adjustment bracket 12.

[0032] Using the above technical solution, the guide rod installed above the clamping sleeve 10 extends through to the outside of the positioning vertical plate 8, providing precise guidance for the movement of the clamping sleeve 10. When the sludge discharge pipe 6 is installed, disassembled, or displaced due to vibration, the guide rod can effectively limit the offset of the clamping sleeve 10, ensuring that it always slides smoothly along a straight line, making the clamping process between the clamping sleeve 10 and the sludge discharge pipe 6 smoother and the positioning more accurate, thus enhancing the overall stability of the connection structure of the sludge discharge pipe 6.

[0033] The working principle of this utility model is as follows: Based on the sludge deposition in the sedimentation tank, loosen the adjustment knob 16, adjust the position of the sludge inlet pipe 4 through the adjustment bracket 12, and after the sludge suction pipe is in a suitable sludge suction position, tighten the adjustment knob 16 to fix the adjustment bracket 12, start the sludge pump 3, the sludge pump 3 sucks the sludge in the sedimentation tank through the sludge suction pipe of the sludge inlet pipe 4, and discharges it through the sludge discharge pipe 6. During the sludge discharge process, the clamping sleeve 10 tightly clamps the sludge discharge pipe 6 under the action of the support spring 9, reducing the shaking of the sludge discharge pipe 6. If it is necessary to disassemble or adjust the sludge discharge pipe 6, the clamping sleeve 10 can be pressed appropriately to overcome the elasticity of the support spring 9 and loosen the sludge discharge pipe 6. The electric cylinder 19 is started periodically. The electric cylinder 19 drives the scraper 17 to move in the inner cavity of the sedimentation tank body 1 through the drive rod 18, scraping the sludge at the bottom of the tank to the vicinity of the suction pipe, assisting in sludge discharge and improving the sludge discharge effect.
