Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary structure technology for filter machines, specifically a filter belt tension adjustment device for a rotary vacuum filter machine. Background Technology
[0002] A common but also very difficult problem with disc vacuum filters is belt misalignment caused by the belt drive roller and belt tension roller. The filter belt is a critical component, and its tension has a great impact on filtration efficiency and filter cake quality. If the filter belt is too tight, it will increase the wear of the filter cloth and rubber belt, and also lead to a decrease in filtration efficiency. If the filter belt is too loose, it will cause the filter cake to be loose and unable to maintain compression, which will also affect filtration efficiency and filter cake quality.
[0003] When applying for this invention, the applicant, after searching, discovered a Chinese patent that discloses a "Filter Belt Tension Adjustment Device for Vacuum Filter Machine" with application number "201310253297.8". This patent mainly uses a coarse adjustment device and a fine adjustment device to make large-scale or small-scale adjustments to the filter belt as needed. Although the patent improves the adjustment efficiency in the specification, the tensioning roller needs to be moved during the tensioning process. If it is moved during operation, it will cause the filter belt to fall off. Therefore, according to the applicant's invention, a device that can filter circulating wastewater and separate pollutants has been invented, which solves the problem of pollutants gradually accumulating at the filter cylinder and causing slow flow rate.
