Embodiment

[0028] Example A filter press

[0029] Such as Figure 1 to Figure 4 As shown, the top pressing part and the bottom supporting part in the pressing mechanism of this embodiment cooperate with each other to squeeze the material flowing into the filter mechanism, and then separate the solid and liquid of the material. The material pressure filtration method based on the structure of the device is fast and efficient, and can greatly improve the production efficiency of solid-liquid separation of materials.

[0030] 1. Overall framework 1

[0031] The overall frame 1 is the basic structure of the device, and is used to fix other components of the device, so that each part of the structure is connected to each other. The overall frame 1 is made of metal material and has a firm structure. The overall frame 1 is fixed with a top pressing part, a filtering mechanism and a bottom supporting part in sequence from top to bottom.

Abstract

The invention discloses a filter press, and the filter press comprises an integral frame, a filtering mechanism and a pressing mechanism, wherein the filtering mechanism and the pressing mechanism arefixedly arranged on the integral frame; the pressing mechanism comprises a top pressing part and a bottom supporting part; the filtering mechanism is arranged between the top pressing part and the bottom supporting part, and a feeding pipeline and a water outlet pipeline are communicated with the filtering mechanism. According to the invention, the solid-liquid separation efficiency of materialsis improved, and the bearing pressure of the filter screen in the filter pressing process is reduced. The solid-liquid separator is suitable for the fields of coal mines, metallurgy, pharmacy, sewagetreatment and the like, and is used for solid-liquid separation of materials.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and relates to a solid-liquid separation device, in particular to a filter press. Background technique [0002] As a kind of equipment for solid-liquid separation of materials, filter press is widely used in coal mines, metallurgy, pharmaceuticals, sewage treatment and other fields. At present, the filter press generally adopts a plate-and-frame structure, that is, the filter plates and filter frames are arranged alternately, the two sides of the filter plates are covered with filter cloth, and the filter plates and filter frames are compressed with a pressing device, and then the filter plates and filter frames are pressed together. A filter chamber is formed between them. The plate and frame filter press achieves the purpose of filtering through the extrusion of the filter screen and the material. The filter screen bears high pressure, is easily damaged, has a short service lif...
