Improved belt-type concentration squeezing filtering machine

Abstract

The invention relates to an improved belt-type concentration squeezing filtering machine, which comprises a belt-type concentration section, a filter pressing section, a filter cloth deviation-correcting device, a filter cloth cleaning device, a filter cloth tension device, a reducing motor (2) and an electric control box (3), wherein the belt-type concentration section comprises a feed pipe (1), a water inlet pipe (18), a blow-off pipe (19), a drain pipe (20), a strap shaped filter cloth (4), a tension roller (5), a deviation roller (6), a deviation cylinder (7) and a driving roller (8); the filter pressing section comprises the strap shaped filter cloth (4), tension cylinders (9), the tension roller (5), a squeeze roller (10), the deviation roller (6), a spray pipe (11), the water inlet pipe (18), the deviation cylinder (7) and a dehydration roller (12); and a sliding shaft (13) is connected between the front and the back tension cylinders (9) of the filter pressing section, the spray pipe (11) is arranged beside the dehydration roller (12) on the lower part of the front section of the filter pressing section, and a reverse water-spraying water skip (14) is added below the spray pipe (11). Through the improvements, the improved belt-type concentration squeezing filtering machine greatly reduces the damage times of the strap shaped filter cloth, and the entire machine is more convenient to operate so that the pollution discharging effect of the entire machine is better.

Description

technical field [0001] The invention relates to an improved belt-type thickening press filter, which belongs to the field of environmental protection sludge treatment equipment. Background technique [0002] The belt-type thickening press filter is the most advanced sludge treatment equipment in the prior art, but in the process of use, the movement of the two tension cylinders before and after the filter-press section is inconsistent, and the water spray pipe is set in the belt-type filter cloth of the filter-press section. The flushing filter cloth above the top of the filter is not clean, and the belt filter cloth is easy to run off. The existing deviation control device is a mechanical control mechanism. Once the filter cloth deviates, the mechanical control mechanism will easily cause the filter cloth to tear, break, etc., resulting in shutdown and replacement of the filter cloth, which greatly affects the processing efficiency. .

[0002] The belt-type thickening press filter is the most advanced sludge treatment equipment in the prior art, but in the process of use, the movement of the two tension cylinders before and after the filter-press section is inconsistent, and the water spray pipe is set in the belt-type filter cloth of the filter-press section. The flushing filter cloth above is not clean, and the belt filter cloth is easy to run off, etc.

The existing deviation control device is a mechanical control mechanism. Once the filter cloth deviates, the mechanical control mechanism will easily cause the filter cloth to tear, break, etc., resulting in shutdown and replacement of the filter cloth, which greatly affects the processing efficiency.
