Special medicament preparation plate-frame pressure filtration device

Abstract

The invention provides a special medicament preparation plate-frame pressure filtration device which comprises a pressure filtration tank, a protective cover frame, a movable pressure plate, smashingblades, a threaded push rod, gas ejection pipes and ejection holes. The movable pressure plate is slidably mounted on guide rods via sliders at two ends of the movable pressure plate, a rubber frame is arranged on the outer side of the movable pressure plate, a fixed pressure plate is mounted at the other end of the inner side of the pressure filtration tank, an end of the fixed pressure plate isconnected with the protective cover frame, the threaded push rod penetrates a threaded sleeve at an end of the pressure filtration tank in a threaded manner and is inserted in bearings of a conical push plate, a smashing shaft downwardly extends into a discharge barrel, the smashing blades are welded on the smashing shaft, a liquid loading pipe is inserted in the bottom of the protective cover frame, and a gas inlet pipe downwardly penetrates the protective cover frame to be connected onto the gas ejection pipes. The special medicament preparation plate-frame pressure filtration device has theadvantages that gas with certain pressures can be fed into the special medicament preparation plate-frame pressure filtration device and can be ejected by the ejection holes, and accordingly materials adhered on filter cloth can be quickly and thoroughly blown off; materials which are fed into the discharge barrel can be smashed under the driving effect of a smashing motor, and can be directly smashed to obtain powder.

Description

technical field [0001] The invention relates to the technical fields of plate and frame filter press and pharmaceutical equipment, and more specifically, relates to a special plate and frame filter press device for pharmaceutical preparations. Background technique [0002] Filter presses are divided into plate and frame filter presses and chamber filter presses. The filter press is a kind of intermittent filtration equipment used for solid-liquid separation of various suspensions; it relies on the pressing device to press the filter plate Then the suspension is pumped into the filter chamber and passed through the filter cloth to separate the solid particles from the liquid particles. [0003] For example, in the patent application number: CN201720390844.0, a plate and frame filter press is disclosed, including a frame, a thrust plate, a compression system, a machine beam, a filter plate, a filter cloth, a compression plate and a turning plate. plate, the thrust plate and t...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the present invention provides a special plate and frame filter press device for pharmaceutical preparations. Through structural and functional improvements, the filtrate after the press filter is easily splashed, and the problem of sticking to the filter cloth after the press filter is shaken by vibration is solved. When feeding the material, the material does not fall completely, and the cutting board is used to cut the material, which can only cut the material into two parts, which is not conducive to the problem of post-processing
