Description

Technical Field

[0001] The present application relates to the technical field of storage tanks, and specifically to a sludge storage tank. Background Art

[0002] Sludge storage tanks are mainly used to store sludge generated during sewage treatment. These sludges usually contain complex components such as organic debris, bacterial cells, inorganic particles, colloidal sludge, etc., and have high water content and high organic matter content. They are easy to rot and stink. By storing and treating sludge in sludge storage tanks, it can effectively prevent sludge from posing a threat to the environment.

[0003] A discharge port is usually set at the bottom of the sludge storage tank and equipped with corresponding discharge equipment (such as a screw pump) to discharge the sludge from the tank. The discharge system is usually also equipped with valves, filters and other equipment to ensure smooth discharge of sludge and prevent blockage.

[0004] For example, the patent with announcement number CN214166044U discloses a sludge storage tank, which can make the storage tank and the internal sludge generate high-frequency vibrations, so that the generated salt impurities will not adhere to the inner wall of the storage tank, and can be discharged together with the treated sludge. It also has a good seismic isolation effect, preventing vibrations from spreading to the connected pipes and base.

[0005] However, in actual storage, the sludge itself contains a large amount of water and mud components. When the sludge is stored in the storage tank for a long time, its viscosity may further increase, causing the sludge to easily adhere to the discharge port or the inner wall of the pipe during the discharge process, thereby preventing the sludge from being discharged normally and reducing the discharge efficiency.

[0006] Therefore, it is necessary to provide a sludge storage tank to solve the above problems.

[0007] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] like Figure 1-Figure 2As shown, the present application provides a sludge storage tank, comprising a frame 1 and a tank body 2 fixedly arranged at the upper end of the frame 1, the tank body 2 being a main container for storing sludge, and a feed port 5 fixedly arranged on the tank body 2, the feed port 5 being used to introduce the sludge into the tank body 2 for use;

[0036] A discharge port 6 is fixedly provided at the lower end of the tank body 2, and the discharge port 6 is used to discharge the sludge. At the same time, in order to continuously break up the sticky sludge and prevent it from sticking and clumping, which makes it difficult to discharge, a breaking mechanism 4 is fixedly provided at the lower end of the tank body 2 at the position of the discharge port 6, and the breaking mechanism 4 is used to break up the sludge for processing;

[0037] The breaking mechanism 4 includes a plurality of first cylinders 41 fixedly arranged on one side of the frame 1, and a connecting frame 40 fixedly arranged between the output ends of the first cylinders 41, so that the first cylinders 41 can drive the connecting frame 40 to move vertically along the frame 1;

[0038] At the same time, a cover body 42 is fixedly provided at the middle position of the upper end of the connecting frame 40, and the cover body 42 is located directly below the discharge port 6, so that the first cylinder 41 can drive the connecting frame 40 to move the cover body 42 accordingly. When the first cylinder 41 drives the cover body 42 to continuously approach the discharge port 6 until it is in contact with the discharge port 6, the discharge port 6 can be closed. Conversely, when the first cylinder 41 drives the cover body 42 to continuously move away from the discharge port 6, the discharge port 6 can be opened to discharge the sludge.

[0039] In order to break up the discharged sludge, a first motor 45 is fixedly provided at the lower end of the cover 42. The output end of the first motor 45 passes through the cover 42 and is fixedly connected to a rotating shaft 43. At the same time, the rotating shaft 43 extends into the interior of the tank 2 and is fixedly connected to a breaking blade 44. Therefore, starting the first motor 45 can drive the breaking blade 44 to rotate, thereby breaking up the discharged sludge.

[0040] When the sludge needs to be discharged, the first cylinder 41 can be used to drive the cover 42 on the connecting frame 40 away from the discharge port 6, thereby releasing the sludge inside the tank 2;

[0041] When the sludge is released, the first motor 45 is started to drive the breaking blades 44 to cut and break up the sludge by rotating, thereby reducing the sludge from clumping and blocking the discharge port 6.

[0042] like Figure 1 and Figure 3-Figure 4 As shown, in order to enable the sludge to be discharged quickly from the tank body 2, a pressing mechanism 3 is fixedly provided at the upper end of the tank body 2. The pressing mechanism 3 is used to apply pressure to the sludge, thereby reducing the gaps and clearances of the sludge, making it difficult for the sludge to accumulate in the tank body 2;

[0043] The pressing mechanism 3 includes a mounting cover 30 fixedly mounted on the upper end of the tank body 2, a plurality of support columns 31 fixedly mounted on the mounting cover 30, a fixing plate 32 fixedly mounted on the upper end of the support columns 31, and a second cylinder 33 fixedly mounted on the lower end of the fixing plate 32. The output end of the second cylinder 33 passes through the mounting cover 30 and extends into the interior of the tank body 2.

[0044] At the same time, a pressing plate 35 is fixedly connected to the output end of the second cylinder 33. The pressing plate 35 is used to directly contact the sludge and is suitable for sliding inside the tank body 2. Therefore, the second cylinder 33 can be activated to push the pressing plate 35 downward to compress the sludge, thereby forcing the sludge to move toward the discharge port 6.

[0045] A scraper 36 is fixedly provided around the pressing plate 35, and the scraper 36 is arranged in contact with the inner wall of the tank body 2 so as to clean the sludge on the inner wall of the tank body 2 during the pressing process;

[0046] At the same time, in order to break up the lumps in the sludge during the pressing process, thereby improving its fluidity and making it easier to compact and discharge the sludge, a stirring assembly 34 is installed on the pressing plate 35. The stirring assembly 34 is used to stir the sludge.

[0047] The stirring assembly 34 includes a support rod 348 fixedly mounted on the upper end of the pressure plate 35. A second motor 343 is fixedly mounted on the upper end of the support rod 348. The output end of the second motor 343 is fixedly connected to a driving wheel 344, so that the second motor 343 can drive the driving wheel 344 to rotate.

[0048] At the same time, multiple sets of driven wheels 345 are rotatably provided at the upper end of the pressure plate 35. A belt 342 is connected between the driven wheels 345 and the driving wheel 344, so that the second motor 343 can be started to drive the driven wheels 345 to rotate through the driving wheel 344. A stirring shaft 346 is fixedly provided inside the driven wheel 345. The stirring shaft 346 passes through the pressure plate 35 and extends to the bottom end. At the same time, a stirring paddle 347 is fixedly provided at one end of the stirring shaft 346. The stirring paddle 347 is used to effectively stir the sludge during the descending process, thereby improving the uniformity and fluidity of the sludge.

[0049] When the pressing mechanism 3 starts to work, the second motor 343 will start, generating power to drive the driving wheel 344 to rotate. The driving wheel 344 drives the driven wheel 345 to rotate together through the belt 342, thereby driving the stirring shaft 346 and the stirring paddle 347 to rotate. The stirring paddle 347 will stir the sludge during the rotation process to make it more uniform and fluid, thereby increasing the sludge descending speed and thus improving the discharge efficiency.

[0050] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
