Settling tank with multilayer settling function

Abstract

The invention discloses a settling tank with a multilayer settling function. The settling tank comprises a primary settling tank, a secondary settling tank, and an outlet valve, and is characterized in that the upper edge of the primary settling tank is higher than the upper edge of the secondary settling tank, the lower edge of the primary settling tank is lower than the lower edge of the secondary settling tank; the outlet valve is arranged in the primary settling tank; two sides of the inner of the primary settling tank are provided with stainless steel rails fixed by supports, a stainless steel frame driven by a motor is arranged on the stainless steel rails and moves on the stainless steel rails, a stirring machine, which is provided with a vertically downward stirring rod, is arranged on the stainless steel frame; the primary settling tank is provided with at least one outlet valve, and any two outlet valves are not in the same level no matter in the horizontal direction or the vertical direction. The provided settling tank has the advantages that the re-fermentation rate of algae is reduced, and the settlement becomes more complete.

Description

technical field [0001] The invention relates to a settling tank with multi-layer settling function. Background technique [0002] Seaweed powder needs to be settled during the production of seaweed liquid. At present, most of the sedimentation tanks are primary sedimentation tanks, and the settlement is not complete, and the seaweed is easy to ferment again. Contents of the invention [0003] The purpose of the present invention is to provide a double-stage sedimentation tank which can reduce the probability of seaweed re-fermentation and make the sedimentation more complete. [0004] In order to achieve the above object, the present invention adopts the technical solution as follows: [0005] A settling tank with multi-layer settling function, including a primary settling tank, a secondary settling tank, and an outlet valve, is characterized in that the upper edge of the primary settling tank is higher than the upper edge of the secondary settling tank, and the upper edg...
