Vacuum PPH Filter Barrel

The quality vacuum PPH filter barrel of Xinda Chemical is specially designed for harsh solid-liquid separation conditions.  The main body is made of high-crystallinity polypropylene homopolymer (PPH), which is formed in one piece through an advanced spiral extrusion winding process.  This fundamentally ensures that the equipment has no weld seams and no leakage risk, and it also has excellent resistance to corrosion by strong acids, strong alkalis and various organic solvents.  This device is lightweight and easy to install.  

It also supports flexible customization of filter plate pore sizes and various interfaces based on specific filtration accuracy (5-100μm) and process layout, perfectly meeting the precision filtration requirements of corrosive or high-purity materials in fields such as chemical engineering, new energy battery materials, pharmaceutical crystallization, food processing, and environmental protection.  Compared with traditional metal equipment, it completely eliminates the risk of metal ion contamination, has a longer service life, lower comprehensive maintenance costs and higher operational safety.

Structural composition

Our vacuum PPH filter barrel has a reasonable structure design, mainly consisting of a top cover, a middle tank, a filter tank and a base. On the bottom surface of the tank, there is a concave surface, and on one side, there is a perforation that can be used in conjunction with a double pipe seat. It also includes a bracket, on which a suction filter bottle and a filtration funnel are fixedly connected. The filtration funnel is located above the suction filter bottle, and the bottom of the filtration funnel is sealed and fixedly connected to the feeding port of the suction filter bottle. The filtration funnel consists of a collection hopper and two feeding cylinders, both of which are fixedly connected to the top of the collection hopper. Two valves are installed on the collection hopper, which respectively control the connection between the two feeding cylinders and the suction filter bottles. The bottom of the inner walls of the two feeding cylinders are fixedly connected with filter plates, and the interior of both feeding cylinders can be disassembled and equipped with filtration structures.

Characteristics and advantages

Working principle

Our vacuum PPH filter barrel is connected to a vacuum pump to create a vacuum and uses negative pressure to achieve the filtration and solid-liquid separation of materials. When the filter paper in one of the feeding cylinders is clogged and needs to be replaced, the other one can still work, and the replacement of the filter paper does not affect the operation of the entire vacuum filter, thereby improving the work efficiency.
