Crawler-type filtering equipment for producing algal polysaccharides

Abstract

The invention provides crawler-type filtering equipment for producing algal polysaccharides. The crawler-type filtering equipment comprises a first crawler-type filtering system. The first crawler-type filtering system comprises a first crawler-type filter screen, a first material receiving box and a second material receiving box, wherein the first material receiving box is provided with a first discharge pipe, arranged in a ring-shaped space defined by the first crawler-type filter screen and used for receiving first feed liquor filtered by the first crawler-type filter screen, and the second material receiving box is provided with a second discharge pipe, arranged under the first crawler-type filter screen and used for receiving first filter residues filtered out by the first crawler-type filter screen. The crawler-type filtering equipment for producing algal polysaccharides in the embodiment is good in filtering effect.

Description

technical field [0001] The invention relates to a crawler-type filtering device for seaweed polysaccharide production. Background technique [0002] Seaweed is the main body of marine plants, and there are more than 20,000 kinds of seaweed. It has attracted widespread attention because of its variety, large output and wide use, and has high economic value. Seaweed polysaccharides are widely used in food, textile, rubber, medicine and other fields, and are indispensable and important additives in the production process. [0003] In the process of extracting seaweed polysaccharides, after the seaweed is digested in the previous process, a viscous seaweed polysaccharide paste material is obtained, which contains a large amount of indigestible seaweed skins and undigested residual roots. The material needs to be processed Fine separation and filtration treatment. Traditional filtration equipment has the following disadvantages: 1) The design capacity of single-layer filtration...

Problems solved by technology

Traditional filtration equipment has the following disadvantages: 1) The design capacity of single-layer filtration is too small, and the filtration accuracy is low

2) The transmission wheel is made of carbon steel, and the part in contact with the material is prone to rust, which affects product quality

3) The driving wheel and the driven wheel are driven by a flat belt, which is easy to deviate, easy to run out of material, and easy to damage the filter screen

4) The steel chain used for transmission between the reducer and the sprocket needs to be lubricated with oil, which is easy to pollute the material and affect the product quality

5) The filter screen is not rinsed thoroughly, it is easy to paste the filter screen, and the filter screen is replaced frequently, which increases the production cost

6) The filter screen and the flat machine belt are fixed with carbon steel bolts. The f
