Walking driving device for filter plate of filter press

Abstract

The invention discloses a walking driving device for a filter plate of a filter press. The walking driving device comprises a rack; a fixed end plate is arranged at one end of the rack, and a movableend plate is arranged at the other end of the rack; a plurality of filter plates are arranged between the fixed end plate and the movable end plate; side beams are arranged on the two sides of the rack; a driving support is arranged on the rack; side beam sleeving holes are formed in the two sides of the driving support; the side beams penetrate through the side beam sleeving holes; and idler wheels rolling on the side beams are arranged at the front ends and the rear ends of the upper sides and the lower sides of the side beam sleeving holes. A hydraulic driving mechanism for driving the idler wheels to rotate is arranged in the driving support, and the idler wheels run on the side beams when rotating so as to drive the movable end plate to move and further drive the filter plates to be mutually pressed or separated.

Description

Technical field[0001]The invention relates to a walking driving device for filter plates of a filter press, belonging to the field of filter press machinery.Background technique[0002]The filter press relies on the opening between the filter plates to form a temporary closed cavity to realize the feed pressure filter. When the filter plate is closed and compressed, a relatively closed cavity is formed between the filter plates. When the material is pressed into the cavity, under the action of pressure, the liquid in the material is discharged from the cavity through the filter cloth, and the solid in the material is Intercepted in the middle of the filter cloth in the cavity, this process is called filter press.[0003]When the filter plate is opened, the filter cake formed between the filter plate cavities is separated from the filter plate. This process is called unloading. The rear end of the general filter press is provided with an squeeze cylinder, which squeezes or stretches the ...

AI Technical Summary

Problems solved by technology

The opening and closing space of the filter plate of the existing filter press is limited by the stroke of the extrusion cylinder

For a general horizontal beam filter press, the filter plate is installed vertically and the oil cylinder is installed horizontally. Since the oil cylinder rod is stretched out, the self-weight is relatively large, which may easily cause damage to the seal of the oil cylinder. In general, in order to ensure the long-term stable operation of the equipment , the stroke of the cylinder is relatively short

Therefore, in the process of opening the plate of the filter press, the plate opening space that can be formed is small, and generally only one or several filter plates can be opened at the same time.
