Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a separation device for urban sludge treatment. Background Art

[0002] With the development of cities, the amount of urban sludge generated in the sewage treatment process is increasing. The composition of these sludges is complex, containing a large amount of water, organic matter, inorganic matter and microorganisms. If they are not effectively treated and separated, they will cause serious pollution to the environment and waste the potential resources.

[0003] In the prior art, after the sludge is separated from the sewage, the solid-liquid separation is performed through a filtering mechanism, and the sludge obtained after the separation is collected. Since the sewage can be mixed with the sludge, only the sewage that is not mixed with the sludge can be separated after filtering by the filtering mechanism, and the sewage mixed with the sludge cannot be separated, resulting in the sludge after filtering and separation containing more sewage, which is inconvenient to treat the sludge;

[0004] The existing patent (publication number: CN216497754U) discloses a sewage sludge separation device for sludge treatment. This utility model drives the first rotating shaft to rotate after the motor is powered on. After the first rotating shaft rotates, it drives the first extrusion member to rotate. After the first extrusion member rotates, it squeezes the sludge passing through the filter plate and the first extrusion member. When the squeezed sludge passes through the second extrusion mechanism, the second extrusion mechanism squeezes the sludge again, effectively reducing the moisture contained in the sludge.

[0005] In view of the above problems, existing patents have provided solutions, but the above patents are unable to clean the filter plates used to filter sludge and sewage, so that the filter screen that has not been continuously cleaned is very easy to be clogged by sludge and cannot fully exert its filtering effect, resulting in incompletely filtered sludge carrying sewage through the filter plates, resulting in incomplete separation and affecting the subsequent treatment effect.

[0006] Therefore, a separation device for treating urban sludge is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. This application sets up a separation mechanism, and allows the sludge to slide smoothly to the position of the electric beating rod through the inclined plate.

[0042] Working principle: In the process of urban sludge separation and treatment, the sludge first enters the separation box 1 through the feeding hopper 2. In the separation box 1, the sludge slides smoothly to the position of the electric beating rod 10 under the guidance of the inclined plate 301. The electric beating rod 10 is started to beat the sludge, so that the solid particles and water in the sludge are better separated, thereby improving the separation effect. The beaten sludge then falls to the surface of the separation net 303. Above the separation net 303, the electric extrusion cylinder 302 squeezes the sludge to squeeze out the residual water therein.

The key separation net 303 plays a filtering role, effectively separating the solid particles and sewage in the sludge, while the reciprocating cleaning structure 305 at the bottom of the separation net 303 continues to work, and the reciprocating motor 3051 drives the screw rod 3052 to rotate, so that the threaded connection on the screw rod 3052 The moving block 3053 moves left and right, and the cleaning brush 3054 on the top of the moving block 3053 moves accordingly to clean the bottom of the separation net 303 to prevent the separation net 303 from being blocked by sludge and unable to fully play its filtering role, thereby ensuring that the separation net 303 always maintains good filtering performance. The sewage obtained after squeezing drips into the U filter screen 401 of the sludge conveying mechanism 4 for filtering again. The conveying motor 402 on the left side of the separation box 1 drives the shaft 403 to rotate, and the spiral conveying blade 404 on the outside of the shaft 403 will slide to the sludge on the right side of the U filter screen 401 and directly transport it to the position of the sludge discharge valve 5, and then discharge it from the separation box 1 through the sludge discharge valve 5, thereby ensuring the continuity and stability of the entire treatment process and avoiding the accumulation and blockage of sludge during the treatment process. The sludge discharged from the sludge discharge valve 5 falls into the sludge collecting box 8 inside the protective frame 7 for collection. The push-pull handle 9 on the right side of the sludge collecting box 8 and the moving wheel at the bottom facilitate the transfer and treatment of the collected sludge.
