Novel automatic pulling plate filter press and use method thereof

Abstract

The invention discloses a novel automatic pulling plate filter press. The filter press comprises a split limiting type filter pressing box body, a modularized elastic sealing filter pressing device and an automatic control circulation pulling plate device, and the split limiting type filter pressing box body is arranged on the automatic control circulation pulling plate device; and the modularized elastic sealing filter pressing device is arranged in the split limiting type filter pressing box body. The invention belongs to the technical field of pulling plate filter presses, and particularly relates to the novel automatic pulling plate filter press and a use method thereof. A longitudinal filter pressing method is creatively used, so the filter pressing efficiency is greatly improved; the bottom baffle of a filter plate is designed to be of a sealed structure, the top baffle of the filter plate is designed to be of a filter screen structure, and a slope flow guide face of a filter pressing water tank is matched, so that the problem that automatic drainage cannot be achieved through self-weight in longitudinal filter pressing is solved; and elastic modules are used for compensating the position movement between each group of filter pressing devices during volume compression, so that the problem that the efficiency bottleneck of the pull plate filter press in the current market is difficult to break through is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of pull-plate filter presses, and specifically refers to a novel automatic pull-plate filter press and a use method thereof. Background technique [0002] Pull plate filter press is a kind of filter press. It is a solid-liquid separation equipment with simple structure, strong applicability and intermittent operation. Discharge after extrusion to achieve solid-liquid separation. [0003] At present, the pulling plate filter presses on the market are all in the way of horizontal compression. Before compression, the material is filled into the compression plate, and then the high-pressure gas is introduced, and the moisture in the material is squeezed out through the extrusion of the gas, but this kind of The compression disc itself takes up quite a lot of space, and only a small amount of material can be injected into each compression disc. After the press filtration is completed, the material is in the shap...

[0003] At present, the pulling plate filter presses on the market are all in the way of horizontal compression. Before compression, the material is filled into the compression plate, and then the high-pressure gas is introduced, and the moisture in the material is squeezed out through the extrusion of the gas, but this kind of The compression disc itself takes up quite a lot of space, and only a small amount of material can be injected into each compression disc. After the press filtration is completed, the material is in the shape of a cake, and the material occupies only about 30% of the space in the entire compression device. This is mainly due to the limitation of the amount of material injected into each compression disk during horizontal compression, otherwise it will overflow under the action of gravity, while in vertical compression, the material can be received by the compression disk because the direction of gravity is perpendicular to the direction of the compression disk. live, the upper limit of compression efficiency is obviously much higher than the horizontal

[0004] However, longitudinal compression has been unable to be popularized due to technical difficulties such as inconvenient drainage and difficulty in maintaining a fixed position after pulling the plate.

[0005] Moreover, the existing automatic plate pulling machine uses gas to compress, and there is no advantage in effect and cost compared with mechanical rigid compression, mainly because the filter plate of the existing plate pulling machine is fixed during the filter pressing process, so Press filtration can only be carried out by occupying the material space. In order to solve the above problems, the present invention proposes a vertical filter press that can automatically drain, pull the plate, and position. It uses mechanical rigid compression and can compensate for positional deviation during compression. automatic pull plate filter press
