Technical Field
The invention belongs to the field of filter presses, and particularly relates to a water mold for a plate-frame filter press.
Background
Plate and frame filters are used for the separation of solids and liquids. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has higher solid content and excellent separation effect. The basic principle of solid-liquid separation is as follows: the mixed liquor flows through the filter medium (filter cloth), and the solids stay on the filter cloth and gradually accumulate on the filter cloth to form a filter mud cake. While the filtrate portion permeates the filter cloth to become clear solution without solids.
The filtering mechanism of the plate-and-frame filter press consists of material molds and water molds which are arranged alternately, and the traditional water molds have the following problems: 1. the water mold can only play a role of sealing water in a compressed state, and the water cannot be sealed when the filter plate is pulled open; 2. there is no water guide structure on the rubber, which will cause damage to the rubber and permeable layer during filter pressing.
