Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sludge treatment, and in particular relates to a sewage sludge storage device. Background Art

[0002] After environmentally friendly treatment, wastewater can be directly recycled or discharged into the ecological environment as clean water. During the environmentally friendly wastewater treatment process, such as through physical, microbial, and chemical treatment methods, a large amount of organic and inorganic matter in the wastewater is decomposed, degraded, and precipitated to form a large amount of organic sludge.

[0003] Organic sludge is not only highly polluting but also difficult to treat harmlessly. Therefore, existing technologies have been used to recycle organic sludge into recyclable materials, such as activated carbon that can be used in industry after high-temperature treatment.

[0004] After desilting the sewage pool, a large amount of organic mud needs to be stored in the mud tank. However, since the organic mud is very easy to stratify during the storage process, the mud material is severely dried due to dehydration. After drying, the mud is not only severely stratified, but also has an uneven distribution of organic matter content. At the same time, drying makes subsequent discharge difficult.

[0005] Therefore, the slurry needs to be stirred evenly during storage to avoid severe stratification and dehydration. However, due to the high viscosity of the slurry, traditional mixing structures are simply unable to stir the high-viscosity slurry and maintain a uniform slurry.

[0006] Specifically, the mixing mechanisms of traditional storage tanks, such as paddle, plate, and impeller types, are unable to fully agitate the slurry. Especially before discharge from the tank, if the slurry is not fully agitated, especially dried slurry, it will not be able to be discharged from the bottom of the tank. Utility Model Content

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0041] Example 1

[0042] like Figure 1-5 As shown, a sewage slurry storage device includes a slurry storage tank. The shape of the slurry storage tank is as follows: the slurry storage tank includes a cylindrical portion 11, and the cylindrical portion 11 is integrally formed with a tapered portion 12 (to facilitate the discharge of slurry).

[0043] At the same time, the top opening of the cylindrical portion 11 is fixedly connected to the top of the mud storage tank and the top of the mud storage tank is fixedly connected to the annular track seat 13 .

[0044] In order to ensure that the mud is fully stirred during storage and subsequent discharge, the mud can be avoided from stratification and drying out (upper mud) after severe stratification, which may lead to difficulty in subsequent discharge and uneven distribution of organic matter in the mud.

[0045] The mud storage tank is equipped with a mud stirring mechanism, which includes two roller frames 21 that roll on the top of the mud storage tank (the roller frames 21 roll on the top of the annular track seat 13). The roller frame 21 includes a roller frame, and a roller wheel 22 is rotatably connected to the roller frame.

[0046] A bridge 23 is fixedly connected between the rotating roller frames 21 (the bridge 23 is fixedly connected between the roller frames). Edge stirring structures near the edges of the mud storage tank are mounted on both sides of the bridge 23. Meanwhile, a central stirring structure located in the center of the mud storage tank is mounted on the center of the bridge 23.

[0047] The edge stirring structure is used to stir the mud at the edges of the tank body, and the center stirring structure is used to stir the mud at the center of the tank body. The technical defect that thick mud is difficult to stir is solved by separate stirring methods.

[0048] Example 2

[0049] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the specific structure of the edge stirring structure is as follows:

[0050] The edge stirring structure includes a plurality of folding rods 26 , and spiral blades are fixedly connected to the outer side walls of the folding rods 26 .

[0051] Specifically, the folding rod 26 comprises a vertical portion positioned perpendicularly within the cylindrical portion 11. This vertical portion is integrally formed with an oblique portion 261 positioned within the conical portion 12. Vanes are helically wound around the vertical portion and oblique portion 261. The helical blades correspond to the shape of the folding rod 26. The design of the folding rod 26 allows the slurry within the cylindrical portion 11 and conical portion 12 to be stirred at the edges during operation, tailored to the tank's shape. The helical blades provide minimal stirring resistance and achieve finer slurry.

[0052] Similarly, the central stirring structure includes a fixed frame 27 installed in the bridge frame 23. The bottom of the fixed frame 27 is fixedly connected to a plurality of vertical stirring rods, and the vertical stirring rods are fixedly connected to blades with a spiral structure.

[0053] The above-mentioned mud stirring mechanism also includes a drive motor 24 for driving the bridge 23. Specifically, a U-shaped drive frame is fixedly connected to the top center position of the bridge 23, and the output shaft of the drive motor 24 is fixedly connected to the U-shaped drive frame.

[0054] At the same time, a motor mounting bracket 241 is fixedly connected to the top of the driving motor 24 , and both ends of the motor mounting bracket 241 are fixedly connected to the outer side wall of the annular track seat 13 .

[0055] During operation, the mud stirring mechanism is driven by the driving motor 24 to rotate in a rolling manner, and the mud is fully stirred during the rotation process.

[0056] Example 3

[0057] like Figure 1-5 As shown, based on the structure of Example 2, this embodiment has a rectangular opening in the bridge 23, in which a plurality of sliding adjustment screws 231 are fixedly connected; a slider 25 slidably connected to the sliding adjustment screw 231 is fixedly connected to the top of the vertical portion of the folding rod 26, and a plurality of pairs of nuts 2311 positioned on both sides of the slider 25 are threadedly connected to the sliding adjustment screw 231.

[0058] This method allows the relative position between the folding rod 26 and the inner wall of the tank to be adjusted during operation, making it convenient to adjust the stirring position. For example, after the edge of the mud is evenly stirred, the folding rod 26 can be adjusted toward the center to continue stirring and dispersing the mud inward. The specific method is to adjust the position by adjusting the nuts 2311 positioned on both sides of the slider and then sliding the adjustment screw 231.

[0059] The fixing bracket 27 is fixed at the center position between the sliding adjustment screws 231 .

[0060] Example 4

[0061] like Figure 1-5 As shown, this embodiment builds on the structure of Example 3, with a tubular discharge portion 121 integrally formed at the bottom of the tapered portion 12. The tubular discharge portion 121 is opened and closed by a plunger mechanism. Specifically, the plunger mechanism includes a plug 33 of a cylindrical structure that blocks the tubular discharge portion 121; the bottom of the plug 33 is fixedly connected to a base 32. The plunger mechanism also includes a bracket 31 fixedly connected to the outer wall of the tubular discharge portion 121. Several lifting cylinders 34 are fixedly connected to the bracket 31, and the piston rods of the lifting cylinders 34 are fixedly connected to the top edge of the base 32. The cylinder barrels of the lifting cylinders 34 are fixed to the top of the bracket 31, and their piston rods are slidably connected to the bracket 31. The bottom of the piston rods is fixedly connected to the top edge of the base 32.

[0062] The plug 33 is driven to rise and fall by the cylinder to block or open the tubular discharge portion 121. After opening, the evenly stirred slurry is tilted for discharge. After discharge, the tubular discharge portion 121 is blocked by the plug, so that convenient discharge is achieved in this way.

[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
