It is suitable for dehydrating coal sludge in coal washing plants, dehydrating sludge in sewage treatment plants, dehydrating sludge in paper mills, and dehydrating hazardous waste. The existing public patent (Announcement No. CN204737339U) discloses a filter material output device for a vertical filter press, which includes a housing, a filter plate, a rotating shaft, a conveyor belt, a feed port, and a feeding mechanism. The feeding mechanism consists of a conveying pipe, a motor, and a rotating shaft. The rotating shaft is provided with spiral blades, which can be driven by the motor to rotate the rotating shaft and the rotating blades to transport the filter material in the conveying pipe to the discharge port. This material transportation method replaces the traditional belt conveyor material transportation method, which solves the problem that the filter material often sticks to the belt, causing inconvenience in use. At the same time, it can also effectively collect the filter material to prevent the filter material from splashing out during transportation. An arc-shaped baffle is provided on the left or right side of the rotating shaft to prevent the filter material from splashing out when it is unloaded from the conveyor belt.
