Rubber filter belt, filter machine belt (vacuum belt)

Hangzhou Hezi Technology

 

Rubber filter belts, also known as vacuum belts, are key components of vacuum belt-type washing machines and DU horizontal belt vacuum filters.

Features:
The surface of the belt body has a row of transverse grooves, with one or more rows of drainage holes in the grooves. The drainage hole section can use a pure rubber structure; the skeleton layer of the belt body is made of high-strength polyester canvas or nylon canvas; the upper and lower covering rubber of the filter belt can use different formulas according to working conditions to meet various needs such as acid and alkali resistance, heat resistance, oil resistance, and cold resistance; the molding and vulcanization of the rubber belt adopt a one-time overall composite process, ensuring the flatness of the belt body and the stability of its performance.


Acid and alkali resistant filter belt
Suitable for working environments that come into contact with acids and alkalis, such as: phosphate fertilizer, alumina, catalysts (4A zeolite), and other industries. The covering rubber uses a rubber-plastic blend material filled with acid and alkali resistant inert media, which has superior acid and alkali resistance compared to chloroprene rubber; the skeleton material uses high-strength polyester canvas, which has stronger acid and alkali resistance than cotton canvas; the drainage hole section uses pure rubber, effectively blocking the corrosion of acid and alkali liquids on the skeleton layer, significantly extending the service life of the filter belt.

Heat resistant filter belt
Mainly used for filtering high-temperature materials, with a heat resistance temperature of 800C < heat resistance temperature < 1050C. The covering rubber uses a thermoplastic elastomer with excellent heat resistance and aging resistance; the skeleton layer uses high-strength polyester canvas, and heat-resistant glass cloth can be laid between the covering rubber and the skeleton layer; the drainage hole section uses a pure rubber structure, effectively blocking the impact of high temperature and filtrate on the skeleton material; the service life of the filter belt is significantly improved.

Oil resistant filter belt
Suitable for filtering environments containing various oily materials. The covering rubber uses nitrile rubber with a high acrylonitrile content, and the skeleton layer uses high-strength polyester canvas. It has advantages such as low deformation and change rate of the belt body, high strength, and wide range of use.

Cold resistant filter belt
Suitable for working environments with temperatures ranging from -40C to +70C. The skeleton layer uses polyester canvas, and the covering rubber uses a combination of natural rubber and polybutadiene rubber, featuring high elasticity, impact resistance, and cold resistance.
