Description

A drying mesh belt cleaning device

technical field

The invention relates to the technical field of sludge dryers, in particular to a drying mesh belt dust removal device.

Background technique

In the process of recycling sludge, it is necessary to dry the sludge first, and then proceed to the next step of crushing and stirring. The existing commonly used sludge drying device is a belt dryer. , the interior contains multiple mesh belts. When the internal sludge is conveyed through the mesh belts, the sludge is dried by the external circulating hot air. During the drying process, some small dust will be on the mesh belts. If it falls to the bottom, it needs to be removed in time. Therefore, the existing patent is to install an automatic dust removal device under the mesh belt. When the dust accumulates to a certain thickness, the accumulated dust will be removed. However, the existing mesh belt After a certain thickness of dust accumulates in the gaps of the mesh belt of the dryer, it is easy to cause the hot air circulation to be blocked, resulting in a decrease in drying efficiency. At this time, if the power of the external hot air circulation system is increased, the wind speed of the incoming air The increase will cause the dust accumulated on the dust cleaning device below to be blown, which will affect the collection and discharge of dust.

The existing publication number is CN113788598A, which provides an automatic dust removal device and its working method applied to the sludge belt dryer. The scraper conveying mechanism can clean the fallen sludge dust particles in time, and the soft spiral The setting of the conveying mechanism can discharge the sludge and dust particles in the storage tank in time, realize automation, and effectively improve its cleaning effect, but the dust in the gaps of the mesh belt cannot be completely removed. After a long time of use, it is easy to cause a decrease in drying efficiency caused by blockage in the mesh seams.
