Description

Technical Field

[0001] This utility model belongs to the field of riboflavin fermentation technology, specifically relating to a riboflavin fermentation mechanism. Background Technology

[0002] In the industrial fermentation production of riboflavin, after each batch of fermentation is completed, the inner walls and internal components of the fermentation tank are often covered with a large amount of bacteria, protein, culture medium residues and other mixed organic and inorganic dirt. If these residues are not thoroughly cleaned, they can easily become breeding grounds for miscellaneous bacteria, which will affect the purity and yield of the next batch of fermentation. In addition, the exhaust gas emitted during the fermentation process contains active bacteria and aerosols. If it is emitted directly without effective treatment, it will pollute the production environment and threaten the health of the operators.

[0003] In existing technologies, fermentation tanks are often cleaned manually or semi-automatically in a single operation, and exhaust gases are purified independently through methods such as ultraviolet irradiation, heating, or spraying sterilizing liquid, resulting in high treatment costs. Utility Model Content

[0004] The purpose of this invention is to provide a riboflavin fermentation mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a riboflavin fermentation mechanism, comprising a fermentation cylinder, a top cover screwed onto the top of the fermentation cylinder through an opening, an installation plate provided at the top of the fermentation cylinder, a first pipe installed on the installation plate through a retaining ring, a three-dimensional rotating nozzle connected to the bottom of the first pipe, a sliding plate embedded in the front side of the fermentation cylinder through a groove, a filter layer provided on the sliding plate, a water outlet provided at the bottom of the fermentation cylinder, and the water outlet connected to a spray box through a second pipe.

[0006] Preferably, the three-dimensional rotating nozzle has three spray nozzles.

[0007] Preferably, a cyclone separator is provided on the right side of the fermentation tank. The cyclone separator includes: a shell, an annular inlet at the top of the shell, a waste gas inlet on the left side of the annular inlet, a waste discharge port at the bottom of the shell, and an airflow outlet at the top of the shell.

[0008] Preferably, a third pipe connects the exhaust gas inlet to the fermentation tank.

[0009] Preferably, a spray box is provided at the rear side of the fermentation tank, and a fourth pipe is connected between the spray box and the airflow outlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using a three-dimensional rotating nozzle, this utility model can thoroughly clean the inner wall and dead corner areas of the fermentation tank, significantly improving the cleaning effect and reducing the risk of cross-contamination caused by residues.

[0011] In this invention, the cleaning water is filtered and then enters the spray box through the outlet and the second pipe. After mixing with the bactericidal liquid, it forms an atomized water curtain for waste gas treatment, realizing the recycling of water resources and significantly reducing water consumption and operating costs.

[0012] This invention introduces a cyclone separator to perform preliminary purification of bacteria-containing waste gas, using centrifugal force to remove most of the solid particles and droplets, reducing the processing load of the spray box and improving the overall exhaust gas purification efficiency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1 to 6 The riboflavin fermentation mechanism shown includes a fermentation cylinder 1, with a top cover 3 screwed onto the top of the fermentation cylinder 1 through an opening 2. An installation plate 4 is located at the top inside the fermentation cylinder 1, and a first pipe 6 is installed on the installation plate 4 via a retaining ring 5. A three-dimensional rotating nozzle 7 is connected to the bottom of the first pipe 6. A sliding plate 9 is embedded in the front of the fermentation cylinder 1 through a groove 8, and a filter layer 10 is provided on the sliding plate 9. A water outlet 11 is located at the bottom of the fermentation cylinder 1, and the water outlet 11 is connected to a spray box 15 through a second pipe 12. The three-dimensional rotating nozzle 7 has three spray nozzles 7. 01; A cyclone separator 13 is provided on the right side of the fermentation tank 1. The cyclone separator 13 includes: a shell 131, an annular inlet 132 at the top of the shell 131, an exhaust gas inlet 133 on the left side of the annular inlet 132, a waste discharge port 134 at the bottom of the shell 131, and an airflow outlet 135 at the top of the shell 131; a third pipe 14 connects the exhaust gas inlet 133 and the fermentation tank 1; a spray box 15 is provided on the rear side of the fermentation tank 1, and a fourth pipe 16 connects the spray box 15 and the airflow outlet 135.

[0023] This invention utilizes a three-dimensional rotating nozzle 7 to thoroughly clean the inner wall and dead corners of the fermentation tank 1, significantly improving the cleaning effect and reducing the risk of cross-contamination caused by residues. The cleaning water, after filtration, enters the spray box 15 through the outlet 11 and the second pipe 12, where it mixes with the sterilizing liquid to form an atomized water curtain for waste gas treatment, achieving water resource recycling and significantly reducing water consumption and operating costs. Furthermore, this invention introduces a cyclone separator 13 for preliminary purification of the bacteria-containing waste gas, using centrifugal force to remove most solid particles and droplets, reducing the processing load on the spray box 15 and improving the overall exhaust gas purification efficiency.

[0024] Example 2

[0025] like Figures 1 to 6The riboflavin fermentation mechanism shown includes a fermentation cylinder 1 with an opening 2 at the top. A removable top cover 3 is screwed onto the opening 2 via precision threads, ensuring airtightness while facilitating opening by the operator. An installation plate 4 is fixedly installed on the top of the fermentation cylinder 1. A first pipe 6 is securely installed on the installation plate 4 via a corrosion-resistant retaining ring 5. The first pipe 6 is made of stainless steel and has a three-dimensional rotating nozzle 7 connected to its bottom. The nozzle has three spray nozzles 701, enabling multi-dimensional rotating spraying in space.

[0026] The front side wall of the fermentation tank 1 is provided with a groove 8, and a pull-out slide plate 9 is embedded in the groove 8. A multi-layer composite filter layer 10 is laid on the slide plate 9. The filter layer 10 is composed of activated carbon fiber and non-woven fabric, which has good impurity interception and preliminary adsorption capacity. The bottom of the fermentation tank 1 is provided with a water outlet 11, which is connected to the spray box 15 through a second pipe 12. That is, the water filtered by the filter layer 10 can be collected through the water outlet 11 and then enter the spray box 15 for secondary use.

[0027] After the riboflavin fermentation process is completed, the waste gas accumulated inside the fermentation tank 1 and the residues attached to the inner wall need to be cleaned. During the operation, the staff first unscrews the top cover 3 to connect the inside of the tank with the outside. Then, the water injection pipe of the external water pump (not shown in the figure) is connected to the interface at the upper end of the first pipe 6. After the water pump is started, the water flow is delivered downward along the first pipe 6 and drives the three-dimensional rotating nozzle 7 to rotate. The three spray nozzles 701 of the nozzle spray water. By adjusting the water pump pressure, the rotation speed and water intensity of the nozzle can be precisely controlled to achieve all-round, no dead angle rinsing of the inner wall of the fermentation tank 1. During the rinsing process, the impurities that are peeled off flow downward with the water flow. When they pass through the filter layer 10 on the slide plate 9, the solid residues are effectively intercepted, while the water continues to seep down through the filter layer 10.

[0028] After a period of use, the filter layer 10 can be removed from the fermentation tank 1 by pulling forward the slide plate 9. This allows for the centralized cleaning of impurities accumulated on the filter layer 10 or replacement of the filter material, making maintenance convenient. The filtered water is discharged through the outlet 11 at the bottom of the fermentation tank 1 and introduced into the spray box 15 through the second pipe 12. The spray box 15 is filled with bacteria-containing waste gas generated during the riboflavin fermentation process. The water entering the box mixes with the bactericidal liquid in the spray box 15 and then forms an atomized water curtain through the built-in nozzles, which fully contacts the waste gas. This reduces the concentration of bacteria and dust in the waste gas and realizes the recycling of water resources, achieving the dual purpose of cleaning and waste gas pretreatment.

[0029] Example 3

[0030] like Figures 1 to 6The riboflavin fermentation apparatus shown is based on Example 2, with a cyclone separator 13 located on the right side of the fermentation tank 1. The cyclone separator 13 is mainly composed of a cylindrical shell 131. The top of the shell 131 has a tangentially arranged annular inlet 132, and the left side of the annular inlet 132 is connected to the exhaust gas inlet 133. The bottom of the shell 131 is a conical dust collection section with a discharge port 134, and the top center has an airflow outlet 135. The exhaust gas inlet 133 is connected to the exhaust part of the fermentation tank 1 through a third pipe 14, so that the bacteria-containing exhaust gas generated during the fermentation process can be introduced into the cyclone separator 13. In practical applications, after the high-speed dust-containing exhaust gas enters the annular inlet 132 tangentially, it forms a rotating airflow along the inner wall of the shell 131. Under the action of centrifugal force, the solid particles and liquid droplets in the exhaust gas are thrown towards the wall and fall along the bottom of the cone, and are finally discharged periodically through the discharge port 134.

[0031] The gas after preliminary purification rises axially and is discharged from the air outlet 135 at the top. If the spray box 15 is arranged behind the fermentation tank 1 and connected to the air outlet 135 and the air inlet of the spray box 15 through the fourth pipe 16, the gas treated by the cyclone separator 13 can be further introduced into the spray box 15. In the spray box 15, the gas and the circulating water from the fermentation tank 1 come into secondary contact through the high-efficiency atomization system. The water mist captures residual microbacteria and soluble harmful substances, significantly improving the exhaust gas purification effect.
