Description

Technical Field

[0001] This utility model belongs to the field of fermentation device technology, specifically relating to a high-density fermentation device. Background Technology

[0002] High-density fermentation, also known as high-density culture, generally refers to a culture technique where the cell population density of microorganisms in liquid culture exceeds 10 times that of conventional culture. Increasing the cell density and thus the specific production rate (yield of product per unit volume per unit time) can not only reduce the volume of culture containers and the consumption of culture medium, and improve the efficiency of separation and extraction in downstream processes, but also shorten the production cycle, reduce equipment investment, and lower production costs. Therefore, it has significant practical value.

[0003] Currently, fermentation equipment often lacks cleaning devices for the fermentation tanks, which can easily lead to inadequate cleaning and affect subsequent fermentation processes. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-density fermentation device to solve the technical problem that the current fermentation device lacks a cleaning device, which easily leads to inadequate cleaning and affects the fermentation process.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a high-density fermentation device, comprising a fermentation tank, a feeding hopper, a stirring device, and a discharge pipe. A cleaning device is detachably connected to the top of the fermentation tank. The cleaning device includes a connecting support with an internal cavity, a cleaning pipe rotatably connected to the connecting support, and a driving component disposed within the connecting support for driving the cleaning pipe to rotate. Water outlet holes are dispersedly disposed on the wall of the cleaning pipe. The connecting support is connected to a water supply device and is connected to a connecting hole disposed at the top of the fermentation tank, allowing the cleaning pipe to extend into the fermentation tank.

[0006] Preferably, the drive assembly includes an upper support block, a lower connecting pipe spaced apart from the upper support block, and a drive plate connecting the upper support block and the lower connecting pipe. Multiple drive plates are provided and evenly distributed along the circumference of the upper support block and the lower connecting pipe. The gap between adjacent drive plates communicates with the lower connecting pipe. The lower end of the lower connecting pipe is connected to the cleaning pipe.

[0007] Preferably, the upper support block is connected to the top of the inner cavity of the connecting support via a bearing assembly.

[0008] Preferably, the lower connecting pipe is connected to the bottom of the inner cavity of the connecting support via a bearing assembly.

[0009] Preferably, a water inlet pipe is provided on one side of the connecting support portion, and the water inlet pipe is horizontally aligned with the position of the drive plate.

[0010] Preferably, the cleaning device further includes a connecting block disposed on the connecting support portion, the connecting block having a shape that matches the connecting hole; the connecting block is sleeved on the cleaning tube.

[0011] Preferably, both the connecting block and the connecting hole are designed to be larger at the top and smaller at the bottom.

[0012] Preferably, the connection hole is equipped with a stopper, which is connected to the top of the fermentation tank by a connecting rope.

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] This utility model relates to a detachable cleaning device. When cleaning is needed, the cleaning pipe extends into the fermentation tank and is driven to rotate by a drive device. Water is sprayed out from the water outlets distributed on the cleaning pipe. The rotating water flow effectively cleans the inner wall of the fermentation tank, ensuring cleaning efficiency and preventing interference with subsequent fermentation. The detachable connection allows for easy removal of the cleaning device during fermentation, reducing contamination of the cleaning pipe by fermenting materials. The cleaning device includes a connecting support, a cleaning pipe, and a drive device. The connecting support has an internal cavity connected to a water supply device. The cleaning pipe is rotatably connected to the connecting support and communicates with the internal cavity. Water outlets are distributed on the wall of the cleaning pipe. The drive device rotates the cleaning pipe. During cleaning, the connecting support is connected to a connecting hole at the top of the fermentation tank. The cleaning pipe extends into the fermentation tank, water flows through the connecting support, and water sprays out from the water outlets on the cleaning pipe. The drive device rotates the cleaning pipe, and the sprayed water cleans the inner wall of the fermentation tank. The rotating water flow ensures effective cleaning and prevents interference with subsequent fermentation. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments, and do not limit the scope of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The specific implementation method is as follows:

[0022] like Figure 1 , 2 As shown, a high-density fermentation device includes a fermentation tank 1, a feeding hopper 2, a stirring device 3, a discharge pipe 4, and a cleaning device 8. A support base 5 is placed at the bottom of the fermentation tank 1. A discharge pipe 4 is located at the bottom of one side wall of the fermentation tank 1, and a switch is installed on the discharge pipe 4. The feeding hopper 2 is located at the top of the fermentation tank 1 for feeding materials into the fermentation tank 1. The stirring device 2 is located at the top of the fermentation tank 1, with stirring blades extending into the fermentation tank 1 to stir the mixture during fermentation and increase the fermentation rate.

[0023] A connection hole (not shown in the figure) is provided at the top of the fermentation tank 1, through which a cleaning device 8 can be detachably connected. The cleaning device 8 includes a connecting support 81, a cleaning pipe 88, and a drive assembly. The connecting support 81 is preferably cylindrical, with a cylindrical inner cavity. A water supply device connected to the connecting support 81 supplies water into the inner cavity. The cleaning pipe 88 is rotatably connected to the connecting support 81 and communicates with the inner cavity of the connecting support 81; water outlet holes 89 are distributed on the wall of the cleaning pipe 88, and when the connecting support 81 is connected to the fermentation tank 1, the water outlet holes 89 are located at the portion of the cleaning pipe 88 that extends into the fermentation tank 1. The drive assembly is located inside the connecting support 81 and is used to drive the cleaning pipe 88 to rotate.

[0024] In this embodiment, when a high-density fermentation device is in use, after fermentation is completed, the fermentation liquid is released from the discharge pipe 4. The cleaning device 8 is installed in the connection hole on the fermentation tank 1. The water supply device is turned on, and water enters the cleaning pipe 88 from the connecting support part 81. The drive device is started to drive the cleaning pipe 88 to rotate. Water is sprayed out from the water outlet 89 from the tank wall of the aerated fermentation tank 1 to complete the cleaning. The rotating water flow is more conducive to cleaning the tank wall, ensuring that the cleaning meets the standards, so as not to affect the next fermentation.

[0025] Furthermore, the drive assembly includes an upper support block 84, a lower connecting pipe 86, and a drive plate 85. Multiple drive plates 85 are provided. The upper support block 84 and the lower connecting pipe 86 are spaced apart vertically. The upper and lower ends of the drive plates 85 are connected to the outer walls of the upper support block 84 and the lower connecting pipe 86. The drive plates 85 are evenly distributed along the circumference of the upper support block 84 and the lower connecting pipe 86. There is a gap between adjacent drive plates 85, and this gap communicates with the lower connecting pipe 86. The cleaning pipe 88 is connected to the lower end of the lower connecting pipe 86. Additionally, the upper support block 84 and the lower connecting pipe 86 are rotatably and sealingly connected to the connecting support portion 81 within their inner cavities. Based on this, water enters the connecting support portion 81 and flows laterally towards the drive plate 85. The rotation of the drive plate 85 drives the upper support block 84 and the lower connecting pipe 86 to rotate, thereby driving the cleaning pipe 88. The entire drive assembly requires no additional power, making it energy-saving and environmentally friendly.

[0026] Furthermore, the upper support block 84 and the connecting support part 81, and the lower connecting pipe 86 and the connecting support part 81 are all connected by bearing assembly 83, and the connection is sealed to prevent water leakage.

[0027] Furthermore, a water inlet pipe 82 is provided on the side wall of the connecting support part 81. The water inlet pipe 82 is aligned with the drive plate 85 and is set perpendicular to the drive plate 85, so that the water sprayed from the water inlet pipe 82 impacts the drive plate 85 at a near-vertical angle, ensuring sufficient impact force on the drive plate 85.

[0028] Furthermore, the cleaning device 8 also includes a connecting block 87. The connecting block 87 is fitted onto the cleaning tube 88, and its shape matches the shape of the connecting hole, ensuring that the cleaning device 8 is stably connected to the fermentation tank 1. In this embodiment, both the connecting block 87 and the connecting hole adopt a design that is larger at the top and smaller at the bottom, ensuring a tight connection and stability.

[0029] Furthermore, the connection hole is also equipped with a stopper 6. The lower part of the stopper 6 matches the shape of the connection hole, making it easy to plug the connection hole when the fermentation tank 1 does not need to be cleaned, thus ensuring a safe fermentation environment inside the fermentation tank 1. More specifically, the stopper 6 is connected to the inner wall of the fermentation tank 1 by a connecting rope 7, preventing the stopper from being lost due to careless placement.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
