Description

Technical Field

[0001] The invention belongs to the field of filtration, and in particular relates to a box-type filtration system. Background Art

[0002] The main equipment for solid-liquid separation and filtration is a filter press. Its working method is that a high-pressure pump pumps the mixed liquid (material) to be filtered into the filter chamber composed of filter plates through the feed port of the filter press. The liquid phase passes through the filter cloth covering the filter plate and flows out of the filter chamber. The solid phase is blocked by the filter cloth in the filter chamber to form a filter cake, and then the filter cake is unloaded to achieve solid-liquid separation. To complete solid-liquid separation and filtration is a systematic project, which is composed of multiple components. From the collection of materials, there are many links such as storage, stirring, high-pressure feed pump, filter press system, filtrate collection and treatment, filter cake collection and treatment, filter cloth cleaning, connection of various functional pipelines, power system, automatic control system, etc., and each link is an indispensable element. For materials with a high rate of difficulty, a stirring and adding device for filter aids should be added. With the enhancement of people's environmental awareness, solid-liquid separation is required in some temporary places or construction sites. It is impossible to place and fix the separated liquids and solids in order according to process requirements in a fixed place for reuse or further treatment. Such as piling sites of various construction sites; dredging of rivers and lakes; drilling construction sites; such separation and filtration sites are generally not restricted and can be carried out by dispersed vehicles. For sites such as underground, tunnels, and offshore drilling platforms, due to site limitations, stringent requirements are placed on the site occupancy of the solid-liquid separation system, that is, to meet production requirements while minimizing the system footprint. At the same time, these sites often require rapid installation and rapid disassembly and removal after work is completed. How to achieve these requirements is a problem currently facing the filtration field. Summary of the invention
