Abstract

The invention provides a device for fixing filtering cloth on a filter plate surface, which comprises the filter plate surface (1), a linear pressure cloth groove (2), a round pressure cloth groove (8) and the filtering cloth (3), wherein the filter plate surface (1) is provided with the filtering cloth (3) of which the joint part is positioned in the linear pressure cloth groove (2), a bottom pressure strip (5) presses on the joint part of the filtering cloth (3), a trapezoidal pressure tank (4) is positioned above the bottom pressure strip (5), and the trapezoidal pressure tank (4) is connected with the bottom pressure strip (5) through a bolt (6). The device can well fix the filtering cloth on the filter plate surface, solve the technical problems in the prior art that the product yield is decreased, the quality is reduced, the production cost is increased, the installation is difficult, the energy source is wasted and the like because of the ageing and the deformation of rubber strips.

Description

technical field [0001] The invention relates to a filter machine for alumina production, in particular to a fixing device for filter cloth on the filter plate surface. Background technique [0002] There are 20 pieces of filter cloth on the horizontal disc filter used by my country's alumina factory for washing and filtering finished aluminum hydroxide. Their joints are fixed in the cloth pressing groove of the disk surface by a diameter of 15mm circular rubber strip 9 and trapezoidal rubber strip 10. During the working process of the aluminum hydroxide washing and filtering horizontal disc filter, the aluminum hydroxide slurry is added to the filter disc surface at a height of about 50mm; then the washing water is continuously added to pump the aluminum hydroxide on the disc surface. Vacuum, so that the liquid in the aluminum hydroxide is sucked away after passing through the filter cloth; stop adding washing water, and after the liquid in the aluminum hydroxide is fully r...
