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...

AI Technical Summary

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 filter screen cannot be used universally, and the maintenance is frequent. When replacing the filter screen, the labor intensity is high, the maintenance time is long, and the carbon steel material pollutes the material

7) The bearing seat has no waterproof design, it is easy to splash into water, the service life of the bearing is short, and the maintenance cost is increased

8) The belt of the flat machine is easy to loose, the adjustment of the tensioning system is cumbersome, the maintenance is difficult and the maintenance time is long

9) The support rod of the filter screen is made of PVC-U material, which is easy to wear, and the worn fine residue falls into the material, which is easy to pollute the material

10) The water receiving box has no slope along the water, the water flow is not smooth, and the remaining time is long and easy to deteriorate, which affects the product quality
