Further, the outer pipe body is communicated with the fermentation tank body, and one end of the inner pipe body extends into the fermentation tank body by 40 cm.
The utility model discloses a theory of operation does: in order to avoid the corrosion of dilute sulfuric acid, a polypropylene PP pipe is connected to the tank body part of the fermentation tank, a polytetrafluoroethylene pipe is lined in a stainless steel pipe, and the dilute sulfuric acid is conveyed in the polytetrafluoroethylene pipe, so that the contact of stainless steel materials with the dilute sulfuric acid is directly avoided, and the corrosion of the dilute sulfuric acid is effectively prevented. Because of the characteristics of high temperature resistance, pressure resistance and acid and alkali corrosion resistance of the polytetrafluoroethylene material, the requirements of sterilization of the fermentation tank are met, meanwhile, the corrosion of dilute sulfuric acid is effectively avoided, the durability of the equipment is improved, and the production safety is also ensured.
In order to be suitable for different workshop environments, the acid supplementing pipeline adopts a combination form of multi-section splicing, so that the production difficulty is reduced, and the applicability is improved. The outer pipe body is spliced through a traditional flange splicing structure, and a disc-shaped butt joint structure is formed on the surface of the flange structure of the outer pipe body by the polytetrafluoroethylene pipe serving as the lining. When two disconnected acid-supplementing pipelines are butted, the two spliced flange structures are locked to provide pressure, and the two disc-shaped butting structures in the interlayer are mutually pressed. In order to improve the sealing effect and prevent leakage, the surfaces of the two corresponding disc-shaped butt joint structures can be respectively provided with a groove and a bulge, and the sealing effect is improved when the two corresponding disc-shaped butt joint structures are buckled with each other. The inner pipe body extends into the fermentation tank body by 40cm, so that the contact between dilute sulfuric acid and the inner wall of the fermentation tank can be effectively reduced, and the corrosion can be avoided.
The utility model has the advantages that: because of the characteristics of high temperature resistance, pressure resistance and acid and alkali corrosion resistance of the polytetrafluoroethylene material, the requirements of sterilization of the fermentation tank are met, meanwhile, the corrosion of dilute sulfuric acid is effectively avoided, the durability of the equipment is improved, and the production safety is also ensured.
