1500 Polypropylene Chamber Filter Plate

I. Product Overview

The Type 1500 polypropylene chamber filter plate is a key component for filter presses to perform solid-liquid separation. The "1500" usually represents the relevant size specifications of the filter plate. Made of high-quality polypropylene material, with its excellent performance, it is widely applied in filter press equipment in numerous industries such as chemical engineering, environmental protection, food, and pharmaceuticals. It provides reliable solutions for the filtration of various materials, facilitating the achievement of efficient solid-liquid separation.

II. Product Structural Features

Dimension Specifications: The external dimensions of this filter plate are generally about 1500×1500mm, and the thickness usually ranges from 70mm to 90mm, depending on the actual design and usage requirements. The diameter of the central feeding hole is approximately 200mm. Such dimensions endow the filter plate with a large filtration area and a suitable filter chamber volume, which can meet the filtration needs of production at different scales and improve the filtration efficiency.

Chamber Structure Design: The filter plate has a chamber structure, with sealing grooves provided around it, where sealing rubber strips can be installed. When the filter press is in operation, adjacent filter plates fit closely together, and the sealing rubber strips play a sealing role to form a closed filter chamber, effectively preventing the leakage of filtrate. The surface of the filter plate is carefully designed with drainage grooves, which can guide the filtrate to flow smoothly out of the filter cloth and be discharged from the filter chamber through the drainage holes on the filter plate, ensuring the smooth progress of the entire filtration process.

Reinforcing Rib Design: In order to enhance the strength and rigidity of the filter plate, enabling it to withstand a large pressure without deforming or cracking during the filtration process, reasonably arranged reinforcing ribs are set on the surface or inside of the filter plate. These reinforcing ribs disperse the pressure, ensuring the stability and reliability of the filter plate during long-term use.

III. Product Material Characteristics

High-Strength Polypropylene: The main material is polypropylene, which has high strength and rigidity. During the filtration and pressing processes of the filter press, it can withstand a large pressure and maintain the structural integrity of the filter plate. Compared with traditional filter plate materials, it performs better in terms of strength and is less likely to be deformed or damaged.

Excellent Corrosion Resistance: Polypropylene has good tolerance to most chemical substances such as acids, alkalis, and salts. This enables the Type 1500 polypropylene chamber filter plate to adapt to the filtration of various corrosive materials. In industries such as chemical engineering and pharmaceuticals, it is often necessary to handle materials containing corrosive components. With its outstanding corrosion resistance, this filter plate can effectively extend its service life and reduce the maintenance cost of the equipment.

Good Temperature Resistance: It can work stably within a certain temperature range, generally able to withstand temperature changes of about 0°C to 90°C. Whether in a cold environment or a high-temperature production workshop, it can maintain good performance and normally perform its filtration function.

Lightweight: The density of the polypropylene material is relatively low, making the filter plate lightweight. This not only facilitates the handling and installation of the filter plate but also reduces the overall load of the filter press and lowers the energy consumption during the equipment's operation.

IV. Working Principle

Filtration Stage: After the filter press is started, a certain number of Type 1500 polypropylene chamber filter plates are closely arranged under the action of strong mechanical force, and the inner cavities between the filter plates form a filter chamber. The material to be filtered is conveyed into the filter chamber under the specified feeding pressure. The solid particles in the material are intercepted by the filter cloth and gradually form a filter cake on the surface of the filter plate; while the liquid part passes through the filter cloth, follows the drainage grooves on the surface of the filter plate, and is discharged from the filter chamber through the drainage holes, thus achieving solid-liquid separation.

Discharge Stage: After the filtration is completed, the pressure between the filter plates is reduced, and the filter plates are loosened. The filter cake falls off from the surface of the filter plate due to its own gravity or with the help of an auxiliary discharge device (such as a scraper, etc.), completing the discharge process and preparing for the next filtration cycle.

V. Application Fields

Chemical Industry: In the processes of chemical raw material production and chemical product purification, it is used to separate various suspension liquids, emulsions, and other materials, such as in the filtration during the production of dyes, pigments, pesticides, fertilizers, etc., effectively removing impurities and improving product purity.

Environmental Protection Industry: It is widely applied in fields such as sewage treatment and sludge dewatering. It can efficiently handle solid pollutants in sewage, dewater the sludge, reduce the moisture content of the sludge, facilitate subsequent disposal and utilization, and reduce environmental pollution.

Food Industry: In the food processing process, such as sugar making, wine brewing, soybean product processing, and juice beverage production, it is used to separate solid residues and liquids, ensuring the quality and taste of products and realizing the recycling of resources at the same time.

Pharmaceutical Industry: In the pharmaceutical production process, it filters and separates various liquid medicines, intermediates, etc., removes impurities and solid particles, and ensures that the purity and quality of medicines meet strict standards.

VI. Product Advantages

Efficient Filtration: With a large filtration area and a reasonable structural design, the filter plate can quickly and effectively perform solid-liquid separation, shorten the filtration cycle, improve production efficiency, and bring higher economic benefits to enterprises.

Long Service Life and Low Cost: The high-quality polypropylene material and the sturdy structural design endow the filter plate with good corrosion resistance, strength, and rigidity, reducing the damage and replacement frequency of the filter plate, as well as the maintenance cost and downtime of the equipment.

Strong Adaptability: It can adapt to a variety of materials with different properties and complex working environments. Whether the materials are acidic, alkaline, or neutral, it can work stably and reliably, meeting the diverse filtration needs of different industries.

Convenient Installation: The lightweight feature makes the installation and disassembly of the filter plate more convenient and quick. At the same time, the structural design of the filter plate also facilitates its connection and coordination with other components of the filter press, reducing the workload and difficulty during the installation process.
