Description

Technical Field

[0001] The utility model belongs to the technical field of biological fermentation tanks and relates to a sealing and feeding device for a biological fermentation tank. Background Art

[0002] Common fermentation tanks are divided into solid fermentation tanks and liquid fermentation tanks. Fermentation tanks are divided into seed tanks (strain fermentation tanks) and fermentation tanks according to their volume and purpose. Fermentation tanks are divided into ventilated fermentation tanks and anaerobic fermentation tanks according to their different aerobic types.

[0003] After searching, for example, Chinese patent literature discloses a biological fermentation tank for improving the efficiency of microbial fermentation [Application No.: CN202322054765.0; Publication No.: CN220618948U]. This includes a biological fermentation tank body, an oxygen tank is arranged on the right side of the biological fermentation tank body, the top of the oxygen tank is connected to an exhaust pipe, a control valve is arranged on the surface of the exhaust pipe, and the top of the exhaust pipe is connected to a hose. An oxygen detector is arranged to detect the oxygen concentration inside the biological fermentation tank body. Although the function of detecting the oxygen concentration of the biological fermentation tank is realized, the problem of insufficient oxygen content in biological fermentation affecting the efficiency of biological fermentation is solved, but when additives and other substances need to be added, multiple positions need to be disinfected, the operation process is cumbersome, and the operation difficulty is high.

[0004] Based on this, we designed a sealed feeding device for a biological fermentation tank. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a sealing feeding device for a biological fermentation tank. The technical problem to be solved by the device is: how to reduce the operating difficulty and simplify the operating steps when sealing and feeding the biological fermentation tank.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A sealed feeding device for a biological fermentation tank comprises a base and a storage tank, wherein a fermentation tank body is arranged on the base, a feeding pipe is connected to the upper end of the fermentation tank body, and a flow valve is installed on the feeding pipe, a sealing cover is threadedly connected to the opening of the storage tank, and a sealing film is fixed on the inner side of the opening of the storage tank, an expansion pipe is connected to the upper end of the feeding pipe, and an internal thread matching the storage tank is arranged on the inner side of the upper end of the expansion pipe, an air intake pipe and a one-way exhaust valve are connected to the frontal end of the expansion pipe, an electromagnetic valve is installed on the air intake pipe, and an opening mechanism for cutting the sealing film is arranged inside the expansion pipe.

[0008] The opening mechanism includes a push rod motor fixed on the outside of the expansion tube, and the output shaft of the push rod motor extends to the inside of the expansion tube, an arc-shaped spring piece is fixed on the output shaft of the push rod motor, and the other end of the arc-shaped spring piece is fixed on the inner wall of the expansion tube, and a cutting blade is fixed on the upper end of the arc-shaped spring piece.

[0009] With the above structure, when in use, the sealing cover on the storage tank is opened, and then the storage tank opening is threadedly connected to the expansion tube with the opening facing downward, and then the solenoid valve is opened to input inert gas or other gases that do not affect the internal reaction of the fermentation tank body into the inside of the expansion tube through the air inlet pipe, and the air inside the expansion tube is discharged through the one-way exhaust valve, and then the push rod motor is extended, and the arc-shaped spring piece is bent upward, so that the cutting blade cuts the sealing film. At this time, the material inside the storage tank will fall into the expansion tube. With the opening of the flow valve, the material can be quantitatively controlled to enter the inside of the fermentation tank body, so as to achieve sealed feeding, and the operation is simple, no disinfection and other operations are required, and the operation difficulty is relatively low.

[0010] The cutting blade is a cross-shaped blade.

[0011] With the above structure, when in use, compared with a straight blade, the cross-shaped blade can cut a larger crack, speed up the falling of the material, and make the sealing and feeding smoother.

[0012] A fixing ring is integrally formed on the inner side of the expanded diameter tube, and a sealing gasket is fixed on the fixing ring.

[0013] With the above structure, when the material storage tank is invertedly threadedly connected to the expansion tube during use, the edge of the material storage tank abuts against the upper surface of the sealing gasket, which can improve the sealing performance of the inside of the expansion tube.

[0014] A dust cover is provided on the expanded diameter tube.

[0015] With the above structure, when it is not necessary to feed materials into the fermentation tank body, the upper end of the expansion tube can be covered with a dust cover to prevent dust from falling into it.

[0016] Compared with the prior art, the sealed feeding device for the biological fermentation tank has the following advantages:

[0017] 1. Through the storage tank, sealing film, expansion pipe, air inlet pipe, opening mechanism and one-way exhaust valve, before feeding, the air between the storage tank and the expansion pipe can be squeezed out by gas that will not affect the internal reaction of the fermentation tank body to prevent it from entering the fermentation tank body, thereby achieving the effect of sealed feeding, the operation process is simple and the operation difficulty is relatively low.

[0018] 2. The sealing film can be cut through the opening mechanism, and the cross-shaped blade can ensure the smoothness of the additive falling. The structure is simple and will not be blocked.

[0019] 3. The sealing gasket is used to further improve the sealing performance inside the expansion tube, prevent air from entering the expansion tube during the feeding process, and improve the sealing effect of the sealed feeding. BRIEF DESCRIPTION OF THE DRAWINGS
