[0023] The present invention will now be described based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0025] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0026] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] Reference Figure 1-2 This utility model provides a sludge storage tank with convenient classification and storage functions, used to store sludge and reduce the moisture content of the sludge. It includes a tank body 1, a sieve plate 2, a support assembly 3, and a heating jacket 4. The support assembly 3 can fix the tank body 1, the sieve plate 2 is disposed inside the tank body 1 for drainage, and the heating jacket 4 is disposed outside the tank body 1, thereby increasing the storage temperature inside the tank body 1.

[0028] A sieve plate 2 is fixed to the middle of the tank body 1. Multiple sieve holes 21 are evenly distributed on the surface of the sieve plate 2. A drain pipe 5 is fixed to the lower end of the tank body 1 and is connected to the tank body 1. When storing sludge, the water in the sludge can gradually flow from the sieve plate 2 into the lower end of the tank body 1 by gravity, and the water can be discharged through the drain pipe 5. This reduces the water content in the sludge stored above the sieve plate 2, lowers the storage difficulty, and facilitates subsequent transportation and processing.

[0029] The tank body 1 includes a cylindrical part 11 and an inverted conical part 12. The inverted conical part 12 is fixed below the cylindrical part 11. The screen plate 2 is a circular plate and is fixed to the lower end of the cylindrical part 11. The drain pipe 5 is fixed to the lower end of the inverted conical part 12. The inverted conical part 12 can provide a water flow slope 141 to increase the water output speed.

[0030] The upper end of the tank 1 is open, and a cover 13 is provided at the upper end of the tank 1. The cover 13 is bolted to the cylindrical part 11, thereby sealing the pipe. Opening the cover 13 allows sludge to be added to or removed from the tank 1. It should be noted that the cover 13 and the tank 1 can be fixed by bolts alone, or they can be combined by a hinge or other connection methods.

[0031] A horizontal plate 121 is fixed inside the inverted conical part 12. A circular plate 122 is slidably connected to the top of the horizontal plate 121 in the vertical direction. There is a gap between the edge of the circular plate 122 and the circumference of the inverted conical part 12. Multiple insert rods 123 are fixed above the horizontal plate 121 and can be inserted into the screen holes 21. After long-term operation, due to the continuous compaction of sludge, the screen holes 21 may become clogged due to the compaction of sludge, which will slow down the water flow rate. At this time, the circular plate 122 is moved upward, and the insert rods 123 can push out the compacted sludge in the screen holes 21 to maintain the dewatering rate.

[0032] In one embodiment, a sleeve 124 is fixed above the horizontal plate 121. A sliding rod 125 is inserted into the sleeve 124, and the upper end of the sliding rod 125 is fixed to the circular plate 122. A spring 126 is installed inside the sleeve 124, and the upper and lower ends of the spring 126 are fixed to the sliding rod 125 and the horizontal plate 121, respectively. Under normal conditions, the spring 126 can drive the sliding rod 125 to move downward. A vertical rod is fixed to the lower side of the circular plate 122. An inclined surface 141 is opened on one side of the vertical rod. A push rod 15 is slidably connected to the inverted cone portion 12 in the horizontal direction. One side of the push rod 15 can abut against the inclined surface 141. When the push rod 15 is pushed in the direction of the axis of the cone portion, it can act on the inclined surface 141 to make the vertical rod rise, drive the circular plate 122 upward, and make the insert rod 123 clean the sieve hole 21. When the push rod 15 is stopped, the circular plate 122 descends under the action of the spring 126, so that water can pass through the sieve hole 21.

[0033] Furthermore, a stop 127 is fixed to the side wall of the inverted cone portion 12 corresponding to the upper side of the push rod 15. A limit strip 151 is fixed to the upper side of the push rod 15. The side of the limit strip 151 away from the axis of the inverted cone portion 12 can abut against the stop 127. The stop 127 and the limit strip 151 cooperate to limit the push rod 15 and prevent the push rod 15 from falling off.

[0034] As one embodiment, the upper end of the insertion rod 123 is chamfered to reduce the collision and wear between the side edge of the insertion rod 123 and the sieve hole 21, and to improve the smoothness of the insertion rod 123 when it is inserted into the sieve hole 21.

[0035] The support assembly 3 includes a mounting ring 31 and support legs 32. The mounting ring 31 is coaxially arranged with the cylindrical part 11 and fixed to the outer periphery of the cylindrical part 11. Multiple support legs 32 are provided and are evenly arranged along the circumferential direction of the mounting ring 31. The support legs 32 are fixed to the lower side of the mounting ring 31 and are used to support the tank body 1.

[0036] A ring 33 is fixed on the upper side of the mounting ring 31. The ring 33 and the mounting ring 31 are coaxially arranged. An annular groove 331 is opened on the inner side of the ring 33. The heating sleeve 4 is fixed in the annular groove 331. The inner side of the heating sleeve 4 abuts against the outer side of the cylindrical part 11. The heating sleeve 4 can adjust the temperature inside the tube to adapt to sludge storage at different temperatures.

[0037] The principle of this utility model is as follows: when storing sludge, the water in the sludge can gradually flow from the sieve plate 2 into the lower end of the tank 1 by gravity, and the water can be discharged from the drain pipe 5, so that the water content in the sludge stored above the sieve plate 2 is reduced, the storage difficulty is reduced, and the subsequent transportation and treatment are facilitated.

[0038] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0039] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
