Vertical type blotter press

Abstract

The invention discloses a vertical filter press, the filter press includes a horizontal plate frame group (1) which is positioned in a main body frame (2), a plate frame group tension drive mechanism (6) and a filter cloth automatic circulating walking mechanism (3) which are arranged on the main body frame (2), a filter cloth washing device (4) and an automatic control system which are arranged below the plate frame group, wherein, a locking pin device (8) is arranged between a movable pressure plate of the plate frame group tension drive mechanism (6) and a plate frame bottom plate (12), and a correction hydraulic cylinder device (7) is arranged on the filter cloth automatic circulating walking mechanism (3). The locking pin device which is arranged thereon reduces the number of the main hydraulic cylinders and reduces the volume and the cost of the filter press; the hydraulic power replaces the pneumatic mode or the screw rod transmission mode of the filter cloth automatic walking system of the filter press, so as to overcome the shortcomings of high requirements and low sensitivity; furthermore, all the power supply of the whole filter press can be completed only by using an oil pressure pump of the original filter pressing system so as to perfect the automatic control system of the filter pressing system.

Description

technical field [0001] The invention relates to a vertical filter press, in particular to a vertical full-automatic filter press with multi-layer plate and frame filter elements. Background technique [0002] Filter presses are mainly used for solid-liquid two-phase separation in mines, metallurgy, chemical industry, electronics industry and environmental protection engineering. The horizontal manual filter plate is made of plastic products, which has low production efficiency and high environmental pollution. The semi-automatic vertical pressurized filter device also uses electronic control methods, but the automatic coordination performance of its mechanism is poor, and its stability and production The efficiency is low, especially when the sealed cavity is under pressure, the equipment will vibrate and spray liquid, and the cleaning of the filter cloth cannot be automated. [0003] The utility model with the patent No. ZL00222138.1 discloses a vertical multi-layer filter...

Problems solved by technology

Some use pneumatic devices, but there are certain conditions for the source of the pneumatic and the stability of the gas source. If it is necessary to increase the gas station

And this invention uses four main hydraulic cylinders for the tensioning of the plate and frame group, which increases the volume of the equipment and the power of the hydraulic pump station, and there are inevitable safety hazards such as leakage and solenoid valve failure in any hydraulic system. The more hydraulic cylinders there are, the more potential safety hazards they have
