Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a mobile sludge dewatering cabin. Background Art

[0002] Sludge is the inevitable product of sewage treatment in sewage treatment plants and sewage stations. If the sludge is not properly treated and disposed of, it will directly cause secondary pollution to the water and the atmosphere after entering the environment, and will also pose a serious threat to the ecological environment and human activities. Therefore, sludge is handled with great caution, and the sludge dewatering machine plays the role of solid-liquid separation in the sludge.

[0003] Most of the existing centrifugal sludge dewatering machines separate solids and liquids through the centrifugal force generated by the rotation of the drum, but the dewatering effect on the sludge is not ideal. The water content in the dewatered sludge is still high, which makes it very difficult for workers to clean up the dewatered sludge. Not only is the dewatering efficiency poor, but it also increases the labor problem of the staff. Utility Model Content

[0004] The utility model aims to provide a mobile sludge dewatering cabin, aiming to solve the above technical problems.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The cam is provided with a toothed structure, the toothed structure is provided with a toothed structure, and a toothed structure is provided on the toothed structure to prevent the toothed structure from being distorted and lost.

[0007] As a further solution of the utility model: the scraping assembly includes a gear shaft, which is rotatably installed on the end of the connecting rod, and a driving gear is fixedly sleeved on the gear shaft. A gear ring is fixedly arranged on the top of the cabin body, and the driving gear is gear-engaged with the gear ring. A scraper shaft is fixedly connected to the bottom end of the gear shaft, and a scraper plate is arranged on the outside of the scraper shaft, and the scraper plate is arranged against the outer wall of the dewatering filter cartridge.

[0008] As a further solution of the utility model: a sliding limit groove is provided at the bottom of the connecting rod, and the top end of the dehydration filter cartridge is adapted to be slidably installed in the sliding limit groove.

[0009] As a further solution of the utility model: the bottom outlet of the feed pipe is arranged directly opposite to the inner cavity of the dehydration filter cartridge.

[0010] As a further solution of the utility model: a pump is fixedly arranged at the upper end of the square cabin body, the input end of the pump is connected to the inner cavity of the square cabin body, and the output end of the pump is connected to a water outlet pipe.

[0011] As a further solution of the utility model: connecting seats are distributed at the four corners of the square cabin body, and the connecting seats are used to connect the square cabin body with the mobile carrier.

[0012] The beneficial effects of the utility model are as follows: the rotating shaft will drive the sleeve and the counterweight guide column in the sleeve to rotate. Due to the centrifugal force generated by the rotation, the counterweight guide column will move outward along the sleeve, so that the extrusion plate will have an extrusion effect on the sludge, thereby being able to more fully squeeze out the moisture in the sludge, effectively improving the dehydration efficiency, and the scraper shaft can revolve around the outer wall of the dehydration filter cartridge while rotating on itself, so that the scraper plate can continuously scrape and clean the outer wall of the dehydration filter cartridge.
