Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically a sludge storage tank for sludge treatment. Background Technology

[0002] Sludge storage tanks are used to store sludge. Through the discharge port at the bottom of the tank, the sludge is transported to the drying tower for drying and then incineration. When sludge is transported from the sewage treatment plant through pipelines or from outside, it is first transported to the storage tank for storage before being processed. However, sludge often produces some odors during the storage process. If these odors are not treated and are discharged directly, they will pollute the environment.

[0003] According to Chinese Patent Publication No. CN220502879U, a sludge storage tank for sludge treatment is disclosed. It filters and adsorbs odors in sludge by setting up a filter mechanism, fixing block, connecting plate, mesh frame, and locking block. At the same time, it is convenient to clean and replace the filter layer. The operation is simple and convenient. It improves the adsorption efficiency of odors and has good effect. By setting up a scraper, a second spring, and a push rod, the second spring provides thrust to the push plate, push rod, and scraper, so that the scraper can scrape the sludge remaining on the inner wall of the tank more cleanly and avoid the residual sludge affecting the storage process.

[0004] However, in this technical solution, when the sludge enters the tank, the sand and gravel contained in the sludge may also enter the tank along with it. When the spiral blades are agitating the sludge, the sand and gravel may collide with the spiral blades, causing damage to the spiral blades and thus greatly reducing the service life of the spiral blades. Therefore, we propose a sludge storage tank for sludge treatment. Utility Model Content

[0008] Preferably, a limiting rod is fixedly installed on the inner wall of the limiting groove, and a rod hole is opened on the limiting slider. The limiting rod moves through the rod hole, and the spring surrounds the outer wall of the limiting rod.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-5As shown, this utility model provides a technical solution: a sludge storage tank for sludge treatment, including a tank body 1 and a purification box 25. A fan 28 is provided between the purification box 25 and the tank body 1, and the purification box 25 is connected to the tank body 1 through the fan 28. A support leg 17 is fixedly installed at the bottom of the tank body 1, and a support frame 19 is fixedly installed at the top of the tank body 1. A motor 2 is fixedly installed at the top of the support frame 19. A rotating shaft 4 passes through the top of the tank body 1, and the rotating shaft 4 is rotatably connected to the tank body 1 through a bearing. The rotating shaft 4 and the motor 2... The transmission connection includes a screen plate 3 slidably sleeved on the outer wall of the rotating shaft 4, which is slidably connected to the inner wall of the tank 1. A support ring 11 is provided below the screen plate 3 and is fixedly installed on the inner wall of the tank 1. A second protrusion 13 is fixedly installed at the top of the support ring 11, and a first protrusion 12 is fixedly installed at the bottom of the screen plate 3. A spiral blade 5 is fixedly installed on the outer wall of the rotating shaft 4. A discharge pipe 15 is connected to the bottom of the tank 1, and a solenoid valve 16 is fixedly installed in the discharge pipe 15. A tank cover 18 is hinged to the top of the tank 1 via a hinge.

[0026] The purification box 25 is disclosed in the announcement number CN221999561U, entitled "A technology in a sludge storage tank for sludge treatment". It discloses that the purification box 25 is provided with a filter layer, a HEPA filter and an activated carbon layer. Therefore, it is not described or drawn in detail in this article and the accompanying drawings.

[0027] Specifically, in the above technical solution, when using the sludge storage tank for sludge treatment, the tank cover 18 can be opened, and then the sludge can be poured into the tank body 1. The sludge will fall onto the screen plate 3. Then, the motor 2 is started, and the motor 2 drives the drive shaft 20 to rotate. The drive shaft 20 drives the connecting shaft 21 to rotate, and the connecting shaft 21 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the screen plate 3 to rotate through the limiting slider 7. The screen plate 3 drives the first protrusion 12 to make a circular motion. When the first protrusion 12 contacts the second protrusion 13, the second protrusion 13 will push the first protrusion 12 to move upward, so that the first protrusion 12 drives the screen plate 3 to move upward, so that the screen plate 3 drives the limiting slider 7 to compress. When the spring 9 moves to disengage from the protrusion 12, the limiting slider 7 will drive the screen plate 3 to move downward under the reset force of the spring 9. When the screen plate 3 rotates continuously, it can achieve up-and-down reciprocating vibration, thereby improving the screening efficiency of the screen plate 3 for sludge. Through the above structure, the screen plate 3 can perform preliminary screening and filtration of sludge, screening out any large sand and gravel that may be present in the sludge to the top of the screen plate 3, preventing sand and gravel from entering the tank 1 along with the sludge. This avoids the problem of the spiral blades 5 colliding with the sand and gravel in the sludge when the rotating shaft 4 drives the spiral blades 5 to rotate, causing damage and reducing service life.

[0028] Furthermore, a limiting groove 6 is provided on the outer wall of the rotating shaft 4, and a limiting slider 7 is fixedly installed on the inner wall of the screen plate 3. The limiting slider 7 is slidably connected to the limiting groove 6. A spring 9 is fixedly connected between the top of the limiting slider 7 and the inner wall of the limiting groove 6. A protective cylinder 24 is fixedly installed on the top of the screen plate 3. The protective cylinder 24 is movably sleeved on the outer wall of the rotating shaft 4.

[0029] By setting a limiting slider 7, the rotating shaft 4 can drive the screen plate 3 to rotate through the limiting slider 7. By setting a protective cylinder 24, the limiting slide 6 can be protected to a certain extent, reducing the possibility of sludge entering the limiting slide 6, ensuring the normal movement of the limiting slider 7 in the limiting slide 6, and thus ensuring the normal vibration of the screen plate 3.

[0030] Furthermore, a limiting rod 8 is fixedly installed on the inner wall of the limiting slide 6, and a rod hole 10 is opened on the limiting slider 7. The limiting rod 8 moves through the rod hole 10, and the spring 9 surrounds the outer wall of the limiting rod 8.

[0031] The limiting rod 8 can limit the spring 9 and ensure its stability during compression.

[0032] Furthermore, there are several protrusions 12 and 13, and the shape of protrusions 12 and 13 is semi-circular. A flow guide 14 is fixedly installed at the bottom of the inner wall of the tank 1.

[0033] By setting up a guide platform 14, the sludge can be more easily guided into the discharge pipe 15 after passing through the guide platform 14.

[0034] Furthermore, a retaining ring 29 is fixedly sleeved on the outer wall of the rotating shaft 4. There are two retaining rings 29. The two retaining rings 29 are slidably connected to the top of the tank body 1 and the inner wall of the tank body 1, respectively. A drive shaft 20 is fixedly installed at the output end of the motor 2. The drive shaft 20 movably passes through the support frame 19. A connecting shaft 21 is fixedly installed at the bottom end of the drive shaft 20. A shaft groove 22 is opened at the top of the rotating shaft 4. The connecting shaft 21 is inserted into the shaft groove 22.

[0035] The retaining ring 29 can support and limit the rotation of the shaft 4, ensuring its stability during rotation.

[0036] Furthermore, a groove pad 23 is fixedly installed on the inner wall of the shaft groove 22. The groove pad 23 is in close contact with the outer wall surface of the connecting shaft 21. The material of the groove pad 23 is wear-resistant rubber.

[0037] By setting the groove 23, the coupling 21 can play a certain role in damping the vibration when it drives the rotating shaft 4 to rotate, thereby reducing the impact of vibration on the motor 2.

[0038] Furthermore, an air intake pipe 26 is connected to the input end of the fan 28, and the air intake pipe 26 is connected to one side of the tank 1. An air guide pipe 27 is connected to the output end of the fan 28, and the air guide pipe 27 is connected to the purification box 25.

[0039] Specifically, by starting the blower 28, the blower 28 can draw in the odorous gas emitted by the sludge inside the tank 1 through the suction pipe 26, and then transport it to the purification box 25 through the air guide pipe 27 for purification and filtration before being discharged.
