technical field

The utility model belongs to the technical field of fermentation equipment, and in particular relates to a convenient cleaning fermentation tank.

Background technique

Fermentation tank is an industrial device used for microbial fermentation. For example, in the biopharmaceutical industry, the cultured strains are fermented in the fermentation tank. During the fermentation process, clean air or oxygen is introduced into the fermenter according to the needs of the fermentation reaction, and the fermented materials are stirred at the same time. During the fermentation process, a large number of air bubbles will be generated. After the sequential fermentation is completed, the fermenter often needs to be cleaned before the next fermentation reaction can be carried out.

It is more difficult to clean the fermenter. The fermenter is elongated and cylindrical, and it is difficult to clean it manually. Now a cleaning device is generally used to clean the inside of the tank. The cleaning effect is not ideal. The reason is that the upper part of the fermentation tank is easy to adhere to the dirt, and the adhesion is often relatively strong. The conventional water pump and water washing method is often used in the prior art, which is not enough to wash away the fermentation. Dirt on the inside of the tank.

Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings in the embodiments of the present invention.

A fermenter that is easy to clean, including a tank body 1, a feed inlet 2, an annular pipe 3, a branch pipe 4, a stirring shaft 5, a motor 6, blades 7, a discharge port 8, a discharge port switch valve 9, and a lower bearing 10 , the first on-off valve 12, the water pump 13 and the cooling pipe 14, the feed inlet 2 is arranged on the upper part of the tank body 1, and the annular pipe 3 is arranged on the upper part of the tank body 1 as a ring-shaped pipeline, through which the 19 communicates with the water outlet of the water pump 13, the first on-off valve 12 is arranged on the water outlet side of the water pump 13, the plurality of branch pipes 4 communicate with the annular pipe 3, and the annular pipe 3 and the branch pipe 4 are provided with several openings facing the tank body 1 The water outlet hole of the inner wall, the stirring shaft 5 is arranged inside the tank body 1, and is rotatably connected with the lower bearing 10 arranged at the inner bottom of the tank body 1, and is driven to rotate by the motor 6 arranged outside the tank body 1, and the blade 7 It is arranged on the stirring shaft 5, the outlet 8 is arranged on the lower side of the tank body 1, the switch valve 9 of the outlet outlet is arranged on the outlet 8, and the cooling pipe 14 is arranged inside the tank body 1 .

As shown in Figure 1, the feed port 2 is used for filling materials, and the stirring shaft 5 drives the blade 7 to rotate under the driving action of the motor 6 to stir the materials to be fermented, and the fermentation rate is adjusted under the cooling action of the cooling pipe 14. temperature, after the fermentation is completed, open the discharge port on-off valve 9, and the material is discharged from the discharge port 8. After a fermentation is completed, when carrying out the cleaning of the fermenter tank body 1, first open the first switching valve 12 at this moment, start the water pump 13, water enters from the water inlet of the water pump 13, and flows through the pipeline 19 into the annular pipe 3 and In the branch pipe 4, it is finally sprayed onto the inner wall of the tank body 1 by the water outlet. As shown in Figure 1, the annular pipe 3 is located at the top of the tank body 1, its outer diameter is close to the inner diameter of the tank body 1, and it is close to the inner wall of the tank body 1, so its water outlet is closer to the inner wall of the tank body 1, By controlling the size of the water outlet hole, a greater impact force of the water flow can be obtained, the distance between the water outlet hole and the inner wall of the tank body 1 is shortened, the loss of kinetic energy of the water flow is reduced, and the impact force of the water flow is greater, which can better flush The dirt on the inner wall of the tank body 1 should be cleaned thoroughly. Cooperate with the cleaning function of the water outlet hole on the upper branch pipe 4, the upper half of the whole tank body 1 is cleaned, so as to get ready for the next fermentation.

The easy-to-clean fermenter includes an air compressor 11 and a second on-off valve 17, the air outlet of the air compressor 11 communicates with the pipeline 19, and the air outlet side of the air compressor 11 is provided with a second on-off valve 17.

As shown in Figure 1, open the second switch valve 17, start the air compressor 11 to ventilate the inside of the tank body 1, the gas enters the annular pipe 3 and the branch pipe 4 through the pipeline 19, and finally sprays out through the water outlet. It has three functions: first, during the fermentation process, the inside of the tank 1 can be ventilated by starting the air compressor 11, such as fresh air or oxygen; second, in the process of cleaning the inner wall of the tank 1 , through the air compressor 11, the compressed gas is passed into the ring pipe 3 and the branch pipe 4, and the compressed gas is sprayed from the outlet hole to the inner wall of the tank body 1. On the one hand, the compressed air speed is high and the impact force is large, so that the dirt on the inner wall can be blown off On the other hand, the cleaned inner wall can be dried; thirdly, when cleaning the tank body 1, start the water pump 13 and the air compressor 11 at the same time, accelerate the water flow, and spray high-speed water from the water outlet hole Air-air mixture increases the impact force of water, and maintains the scouring effect of water, and the cleaning effect is improved.

The easy-to-clean fermenter includes a solenoid valve 20, which is arranged at the outlet end of the air compressor 11, and the solenoid valve 20 is regularly turned on and off.

As shown in Figure 1, the solenoid valve 20 controls the compressed air from the air compressor 11 to enter the pipeline 19, opens the second on-off valve 17, and starts the air compressor 11. When the solenoid valve 20 is regularly turned on and off, for example, with 1 second is the cycle, within the cycle 05 seconds is on, 05 is off, the effect obtained is that the water outlet holes on the annular pipe 3 and the branch pipe 4 intermittently eject high-speed gas or water-air mixture, which impacts the inner wall of the tank body 1 The effect of the load. Compared with a load of the same size, the impact load has a better scouring effect and a better cleaning effect on the inner wall of the tank body 1 .

The fermenter that is convenient to clean includes a sterilizing tube 18, the sterilizing tube 18 is arranged on the water inlet side of the water pump 13, a quartz tube 15 is arranged in the tube wall of the sterilizing tube 18, and a quartz tube 15 is arranged in the quartz tube 15. UV lamp16.
