Description

Technical Field

[0001] The utility model relates to the technical field of spirulina separation equipment, in particular to a spirulina separation device with a liquid return blocking function. Background Art

[0002] After the cultivation of spirulina is completed, it is necessary to extract spirulina from its growth environment, purify and separate it. The separation of spirulina is usually divided into three main steps: primary separation, secondary separation and tertiary separation. The primary separation mainly uses filtration, centrifugation and flocculation methods to initially extract spirulina from its growth environment.

[0003] When primary separation of Spirulina is performed by filtering, the algae liquid in the liquid storage tank is directly transported to the separation device through a delivery pump, and then separated by the filter cloth on the separation device, so that the Spirulina can remain on the filter cloth, and the nutrient solution used to cultivate the Spirulina will be filtered out and discharged. However, when separating Spirulina, the existing separation equipment will tilt the separation equipment to prevent the separation point of the Spirulina from being fixed, so that the Spirulina liquid can flow on the tilted filter cloth to prevent the separation point from being fixed due to the flat placement and affecting the separation effect. However, since the filter cloth is tilted, the Spirulina liquid transported to the filter cloth has a certain impact flow rate, that is, the fast-flowing Spirulina liquid has a large impact force on the filter cloth, making it difficult for the Spirulina to be evenly distributed on the filter cloth, and part of the Spirulina may be washed away or not effectively retained on the filter cloth.
