Sludge dewatering dryer

Abstract

The invention relates to the technical field of sludge treatment equipment, and discloses a sludge dewatering dryer. The sludge dewatering dryer comprises a roller, wherein a T-shaped groove is formed in the top end of the interior of the roller, an M-shaped hole is formed in the portion, located at the top end of the T-shaped groove, of the interior of the roller, an M-shaped pipe is fixedly connected in the hole in a sleeved mode, holes are formed in the portions, located below the two sides of the T-shaped groove, of the interior of the roller, the roller is movably sleeved with a shell through the hole, and a scattering rod is movably sleeved with the lower portion of the interior of the shell. A telescopic bag is compressed through water vapor formed in the sludge drying process, so that the length of the scattering rod extending out of the shell is increased, the extending length of the scattering rod is controlled according to the content of the water vapor, the scattering strength of a scattering device on the sludge is set and controlled according to the extending number of lower beating rods and side beating rods, and therefore the extension length of the scattering rod is increased when the water content of the sludge is large, the force applied to scattering the sludge is large, the scattering device can sufficiently scatter the sludge, and the sludge is prevented from caking or adhering to the inner wall of the roller.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a dryer for sludge dehydration. Background technique [0002] Sludge is mostly produced during the treatment of urban wastewater and factory wastewater. It has the characteristics of high moisture, high viscosity and high water holding capacity. In order to achieve the purpose of environmental protection, sludge is usually treated before being discharged or used, while sludge drying As the last step of sludge treatment, drying is an important link to determine the effect of sludge treatment. The existing sludge drying step usually uses a sludge dryer, which provides heat to the drum through heat transfer oil to promote the evaporation of water in the sludge. [0003] Due to the high moisture and high viscosity of the sludge, in order to prevent the sludge from sticking to the wall of the cylinder or forming agglomerates, the inner wall of the sludge dryer is us...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing sludge dryer proposed in the background technology, the present invention provides a dryer for sludge dehydration, which has the ability to adjust the length of the dispersing device according to the moisture content inside the sludge, so as to promote It has the advantages of fully breaking up the sludge, strengthening the drying effect of the sludge, and improving the drying efficiency, and solves the technical problems raised in the above-mentioned background technology
