Vertical type full automatic plate-and-frame filter press, and filter technique

Abstract

The invention relates to a vertical full automation filter press. The existing filtration filter pressing installment as a result of the structure technology, ,the horizontal hand movement filtration frame which uses the plastic has low production efficiency and big environmental pollution; because the semiautomatic pressure filtration installment also uses the electrical controlled method, but the automated coordination performance of other organization is bad, its stability and the production efficiency are low, specially when the seal cavity bearing, the equipment presents vibration and spray phenomenon. The filter press includes the leveling board frame group, the main body support structure, the board frame group opening and holding apparatus, the filtering cloth automatic cycle running gear, the filtering cloth washing device, automatic control system, hydraulic system, craft circuitry and so on. It uses the vertical structure to realize the full automatic operation, thus has high filter efficiency, low energy consumption, high automaticity, high product quality, easy operation, the simple maintenance, and no pollution.

Description

technical field [0001] The invention relates to a filter press and its filtration process, in particular to a vertical fully automatic plate-and-frame filter press controlled by a PLC (or DCS computer) with a vertical structure and automatic cycle movement of filter cloth and its filtration process. Background technique [0002] The filter press is mainly used for sewage treatment in mining, metallurgy, chemical industry, electronics industry and environmental protection engineering. It is a widely used solid-liquid separation equipment. Due to structural technical reasons, the existing filter press devices mostly adopt horizontal manual or semi-automatic pressurized filtration, and the horizontal manual filter plate frame is made of plastic products, which has low production efficiency and large environmental pollution; semi-automatic vertical pressurized filter device Because the equipment also adopts the electronic control method, but due to the poor automation performanc...

Problems solved by technology

Due to structural technical reasons, the existing filter press devices mostly adopt horizontal manual or semi-automatic pressurized filtration, and the horizontal manual filter plate frame is made of plastic products, which has low production efficiency and large environmental pollution; semi-automatic vertical pressurized filter device Because the equipment also adopts the electronic control method, but due to the poor automation performance of other mechanisms, its stability and production efficiency are low, especially when the sealed cavity is under pressure, the equipment will vibrate and spray liquid, and the filter cloth will It is basically impossible to realize automation in cleaning, and it is impossible to realize fully automatic pressure filtration treatment in the true sense.

[0003] There are also some filtration processes based on vertical automatic filter presses, but due to technical limitations, most of the equipment adopts electronic control, but the stability and production efficiency of the equipment are low, especially when the sealed cavity is under pressure, the equipment will appear Vibration and spraying phenomenon, the environmental pollution is relatively serious, and it is impossible to realize the real full-automatic filter press treatment

The whole process can not achieve the expected filtering effect
