Horizontal vacuum belt type filter and filtering method thereof

Abstract

The invention discloses a horizontal vacuum belt type filter which comprises a rack, a driving roller, a driven roller, a belt support system, an annular belt, a piece of filtering cloth, a vacuum boxmechanism and a feeder, wherein the belt support system comprises a support track and a support track sliding strip; the vacuum box mechanism comprises vacuum boxes, liquid collection branch tubes, airbags, push discs, mounting platforms and vacuum box chutes; the vacuum boxes consist of multiple sections of vacuum box bodies, vacuum box flanges, front vacuum box guides, rear vacuum box guides and vacuum box elbows; the feeder comprises a box-shaped overflowing mechanism, an upper cover and a feeding tube; and the box-shaped overflowing mechanism comprises a box-shaped overflowing cavity, a storage tank, a front buffer tank, a rear buffer tank, a front adjusting plate, a rear adjusting plate, a front inner support, a rear inner support, a front cover plate, a rear cover plate, a left sidesupport and a right side support. By adopting the horizontal vacuum belt type filter, an excellent filtering effect can be ensured, the overall deformation resistance of a vacuum box is improved in the operation process, the feeding amount can be increased, product consumption in the filtering process is reduced, and uniform feeding can be ensured.

Description

technical field [0001] The invention relates to a filtering device, in particular to a horizontal vacuum belt filter and a filtering method thereof. Background technique [0002] Horizontal vacuum belt filter has been gradually used in the filtration of sodium bicarbonate suspension in soda ash production in recent years. The belt support system is a very important mechanism in the horizontal vacuum belt filter. It is used to support the upper half of the horizontal section of the endless belt. Since the filter cloth is directly installed above the endless belt, can the belt support system provide a flat horizontal support? It has a critical impact on the filtering effect. In the prior art, the belt support system relies on air cushion or water cushion support, the air cushion support system cannot provide a real flat surface, any loss of air pressure will cause damage to the expensive belt; the water cushion support system requires a lot of clean water , and in developing...

Problems solved by technology

In the prior art, the overflow mechanism of the feeder is generally a fishtail type, which can only overflow and feed in a single direction. It has no buffer function for the feed slurry, and the feeding is uneven, and the loss of the product to be filtered is high.
