Filter chamber pressure-bearing open-and-close component for filtering element of flexible tube squeezer

Abstract

The invention provides a filter chamber pressure-bearing open-and-close component for a filtering element of a flexible tube squeezer. In the invention, a flexible tube squeezer is high-pressure solid-liquid separation equipment for deep dehydration; and the filter chamber pressure-bearing open-and-close component for the filtering element of the flexible tube squeezer is a component combining a push-pull clamping force balance mechanism with a pressure-applying structure, and the component is related to maintenance of pressure in a filter chamber during the slurry squeezing process and discharge of a filter cake after squeezing. The push-pull clamping force balance mechanism comprises a front swing pressure-bearing plate, a rear swing pressure-bearing plate, an electric actuating mechanism, an upper push-pull cam plate, a lower push-pull cam plate, a traveling mechanism and a horizontal shaft; and by utilizing the component, the filtering element of the flexible tube squeezer can also replace the traditional plate-and-frame diaphragm of a plate-and-frame diaphragm squeezer. The filter chamber pressure-bearing open-and-close component has the advantages of simplified structure, easily controlled sealing pressure, greatly strengthened reliability, lowered manufacturing accuracy and prolonged service life; the component can assist in automatically completing the treatment process and is more beneficial to making big filtering element so as to realize ultra-large-scale treatment; and in addition, the equipment can be loaded on a transport vehicle to form mobile dewatering equipment.

Description

technical field [0001] The present invention relates to a pressure-bearing opening and closing part of a filter chamber of a flexible tube press filter element for solid-liquid separation of viscous and fine-grained substances. discharge. The flexible pipe press adopting this part is especially suitable for papermaking wastewater treatment, sludge treatment, river dredging mud treatment, wet smelting wastewater treatment, coal washing wastewater treatment and livestock and poultry breeding pollutant treatment. Background technique [0002] The push-pull clamping force balance mechanism and the pressing structure proposed by the present invention are the improvement of the pressure-bearing opening and closing parts of the filter chamber of the filter element of the flexible tube press machine proposed by myself; obviously, with a little improvement, the filter element of the flexible tube press machine It can replace the plate and frame of the traditional plate and frame pre...

Problems solved by technology

[0008] In the past, the pressure plate and the pressure plate utilize the fixed suspension guide wheels and filter elements on both sides to move relatively on the upper frame guide rail. figure 1 Putting the pressure bearing plate shown on the rack guide rails of the next level can reduce the load of the rack guide rails on the upper level, improve the overall structure of the rack, and reduce the overall weight of the rack; There must be an intermediate bearing plate between each filter tube unit, which consumes a lot of material; the thickness of the pressure bearing plate in the past was large, and the material consumption was more. Thin and even need to be made shorter to reduce cost

Recently, the design of the permeable plate was adopted in the scheme of the patent application No. 201010116437.3 of "Filter element with multi-layer permeable plate for pressing device", so that the thinning of the pressure bearing plate has become a reality, and the sealing of the filter chamber depends on a The pressure-bearing opening and closing parts of the filter chamber are completed, but in the past design, the pressure-bearing opening and closing parts of the filter chamber need to be hung under a wider pressure-bearing plate, so the filter chamber needs to be pressure-bearing after the pressure-bearing plate is improved or thinned The opening and closing parts need to be improved and a new design scheme is proposed; in addition, the sealing pressure of the pressure-bearing opening and closing parts of the filter chamber in the past is relatively small, and the structure is complicated, which also needs to be improved.

In addition, in the past, the pressure-bearing opening and closing parts of the filter chamber relied on the cylinder as the driving power mechanism, and it was inevitable that the clamping distance of the pressure-bearing opening and closing parts of each filter element was inconsistent, resulting in inconsistent pressing force of each filter chamber and dehydration. inconsistent dryness
