I. Application of Plate and Frame Filter Press in Fiber Stock Solution Filtration
Fiber stock solution is commonly found in industries such as papermaking, textiles, and biomass materials. Its core components are a mixture of fibers (e.g., plant fibers, chemical fibers) and liquids (e.g., water, solvents). The filtration goal is to separate pure fibers or remove impurities from the stock solution to meet the requirements of subsequent production processes.
1. Filtration Principle and Characteristics
The solid particles (fibers) in the fiber stock solution are relatively large in size (usually tens of micrometers to several millimeters) and have certain toughness and adsorption properties. The plate and frame filter press retains fibers through the filter cloth, while the liquid passes through the filter cloth to become the filtrate.
It is necessary to select filter cloths with good air permeability and wear resistance (such as polyester mesh and nylon mesh) to prevent fiber clogging of the filter cloth pores and reduce fiber residue on the filter cloth.
2. Specific Application Scenarios
Papermaking industry: In the pulp preparation process, plate and frame filter presses can filter out fine impurities in the pulp (such as sediment and undecomposed lignin), improve pulp purity, and ensure paper quality. They can also be used to recover fibers from the pulp, reducing raw material waste.
Textile industry: In the production of chemical fiber stock solutions (e.g., viscose fiber, polyester stock solution), filtration can remove gel particles and undissolved polymer impurities in the stock solution, avoiding blockage of spinneret holes during subsequent spinning processes.
Biomass material production: For example, in the filtration of biomass stock solutions such as straw fiber and bamboo fiber, the separated fibers can be used to make boards, composite materials, etc., and the filtrate can be further processed for recycling.

3. Advantages and Precautions
Advantages: It can efficiently retain fibers, and the filter cake (fibers) has a low moisture content, which is convenient for subsequent drying or processing. The equipment has strong adaptability to fibers and can handle high-concentration stock solutions (fiber content can reach 10%-30%).
Precautions: It is necessary to regularly clean the residual fibers on the filter cloth to prevent blockage. The filtration pressure (usually 0.3-0.6MPa) should be adjusted according to fiber characteristics to avoid fiber crushing, which may affect quality.

Product Overview and Model Description
Overview
Filter presses are divided into plate-and-frame filter presses and chamber filter presses. They are intermittent pressurized filtration equipment used for solid - liquid separation of various suspensions. They rely on a pressing device to clamp the filter plates tightly, and then pump the suspension into the filter chamber with a pump. The purpose of separating solid particles and liquid materials is achieved through the filter cloth. The whole machine has a simple structure, good separation effect, convenient use, and a wide range of applications. It is widely used in coal washing, inorganic salts, mining, alcohol, petroleum, chemical industry, fuel, metallurgy, medicine, food, textiles, printing and dyeing, papermaking, and sewage treatment and other fields.
