Large grid plate for air pressure filter

Abstract

The invention relates to a large grid plate for an air pressure filter, which can improve the safety class of food and rice wine taste fundamentally. The surface of a large silicone rubber grid plate forms a concavo-convex liquid-flow surface through multiple cycles of element rests; and the concavo-convex liquid-flow surface is provided with a deflector hole. The large silicone rubber grid plate has the advantages of innocuity, no odor, acid resistance, alkali resistance, high and low temperature resistance, insusceptibility to oxidation and photochemical action and long service life. In addition, the large silicone rubber grid plate not only does not exert any influence on the rice wine taste, but also really retains the original taste and flavor in a rice wine-making process and improves the safety class of the food. The large silicone rubber grid plate improves the squeezing efficiency of squeezed materials effectively to improve the discharging rate of the materials by more than 10 percent and reduces the discharging cost of the squeezed materials effectively. After being discarding as worthless material, the large silicone rubber grid plate can be recycled so as to protect environment.

Description

technical field [0001] The invention relates to a large grid plate specially used for air filter presses, which can fundamentally improve the food safety level and the taste of rice wine, and belongs to the field of manufacturing large grid plates specially used for air filter press machines. Background technique [0002] CN CN201175601Y, name "a plate and frame type diaphragm filter plate", its structural form is: the filter plate is a diaphragm type, the plate frame is a filter cake chamber, and one plate and one frame are combined into a filter unit. The feed hole is at the corner of the plate frame, and the feed hole of the plate frame has a groove leading to the filter chamber, and the filtrate enters the filter chamber through the groove of the feed hole. The outlet hole of the filtrate is at the corner of the membrane filter plate, and it is connected with the undercurrent pipeline. The filter cloth adopts a whole single piece, and there are lock cloth buttons on bot...

Problems solved by technology

Its disadvantages: First, poor elasticity, unable to increase the compression rate of the material, resulting in waste of active ingredients and increasing the direct cost of material retrieving; second, it is not suitable for making rice wine, and the membrane and After the rice wine is in contact, it will not only destroy the molecular structure of the rice wine, but also have any impact on the taste of the rice wine, directly downgrading the food safety level
