The ring belt of rubber belt vacuum filter is continuously driven by the motor. Between the belt and the vacuum slide table, the ring friction belt contacts to form a water seal to prevent the damage of vacuum environment. The main filter medium of rubber belt vacuum filter is press cloth.
When the vacuum chamber of the rubber belt vacuum filter is connected with the vacuum system, the annular rubber belt forms a vacuum extraction zone. Under the pressure of vacuum and gravity, filtrate passes through the filter cloth and enters the vacuum chamber through the rubber belt, while solid particles are trapped by the filter cloth to form a filter cake. The ring rubber belt of the rubber belt vacuum filter will drive the filter cake to move through the washing area and dry area, and finally remove the filter cake.
