Description

Technical Field

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

[0002] Fermentation tanks are core equipment used for microbial culture, cell fermentation, or biochemical reactions, and are widely used in biopharmaceuticals, food fermentation, chemicals, environmental protection, and other fields. Their structure and characteristics directly affect fermentation efficiency, product quality, and process stability. The main body is generally a vertical cylinder made of stainless steel, and strict sealing is required in its design and manufacturing to prevent contamination and leakage. After fermentation, the fermentation tank must be carefully cleaned before it can be used for the next fermentation production.

[0003] Cleaning small fermenters often requires disassembling the tank, cleaning it with a brush, and then reassembling it. The seal must also be verified before it can be used for the next fermentation. Repeated cleaning is not only troublesome but also easily damages the fermenter's airtightness, reducing its lifespan. Disassembling fermenters larger than 100L is even more inadvisable. For fermentations with long fermentation times and sticky culture media, ordinary brushes often stick during cleaning, forming a ring of residue on the inner wall that is difficult to remove with ordinary sterilization.

[0004] Based on the above problems, those skilled in the art urgently need to develop a fermentation cleaning device that can clean the inside of the fermentation tank without disassembling the tank body, can clean residues of different viscosities, will not stick to the brush, and is suitable for fermentation tanks of different sizes. Summary of the Invention

[0005] This invention aims to solve the technical problems in the prior art by providing a fermentation tank cleaning device. This cleaning device uses a pneumatic motor to drive a connecting rod, guiding a brush to rotate for internal cleaning of the fermentation tank. The speed of the aeration motor can be adjusted by changing the air intake volume to accommodate residues of varying viscosities.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] This utility model provides a fermentation tank cleaning device, which includes an installation platform, a shell, a first connecting rod, a second connecting rod, and a brush.

[0008] The outer casing is located on the upper part of the mounting platform, and a pneumatic motor is installed inside the casing. One end of the pneumatic motor is connected to an air inlet pipe, and the other end is connected to a first connecting rod, which is wrapped by a sleeve. The bottom of the first connecting rod is connected to a second connecting rod via a gear, and the bottom of the second connecting rod is connected to a brush. A flexible hose is installed on the sleeve, with one end connected to a faucet and the other end being a compressed nozzle. The compressed nozzle corresponds to the brush, allowing the cleaning liquid in the hose to be sprayed onto the brush for simultaneous brushing and cleaning.

[0009] Furthermore, the first connecting rod is provided with several limiting slots, which can adjust the length of the first connecting rod to meet the cleaning depth requirements of fermenters of different sizes.

[0010] Furthermore, the end of the second connecting rod is a threaded connection, which allows for quick brush replacement for cleaning of residues with different hardness and viscosity.

[0011] Furthermore, a micro-perforated waterproof camera is installed on the sleeve to monitor the cleaning effect in real time.

[0012] Furthermore, the end of the intake pipe is connected to a compressed air source.

[0013] Furthermore, handles are provided on both sides of the outer casing.

[0014] Furthermore, the hose is a rubber hose or a PPR hose.

[0015] Furthermore, the gear is made of carbon steel or stainless steel.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This fermentation tank cleaning device can directly insert the connecting rod into the fermentation tank, drive the connecting rod to rotate via a pneumatic motor, and guide the brush to rotate via gears to clean the inside of the fermentation tank.

[0018] 2. This fermenter cleaning device can change the speed of the aeration motor by changing the amount of air intake, thus meeting the cleaning requirements for residues of different viscosities.

[0019] 3. This fermenter cleaning device is equipped with a hose for introducing cleaning solution. The cleaning solution can be sprayed onto the brushes through a compressed nozzle, allowing for simultaneous brushing and rinsing. This ensures that the brushes remain clean and do not stick while cleaning the fermenter.

[0020] 4. The connecting rod of this fermenter cleaning device is adjustable in length to accommodate tanks of different depths; the cleaning device is also equipped with a waterproof camera for real-time monitoring of the cleaning status inside the tank.

[0021] 5. The brush head of this fermenter cleaning device is detachable, and can be adapted or replaced with brushes of different hardness to deal with residues of different viscosity and hardness.

[0022] 6. This fermenter cleaning device avoids the shortened service life and manual technical difficulty caused by frequent disassembly and cleaning of small fermenters, and improves the problem of difficult cleaning of large fermenters. Compared with traditional cleaning devices, it has the characteristics of cleaning more thoroughly and being more practical. Attached Figure Description

The bottom of the first connecting rod 9 is connected to a second connecting rod 10 through a gear 11. The bottom of the second connecting rod 10 is connected to a brush 6. A flexible hose 4 is provided on the sleeve 5. One end of the flexible hose 4 can be connected to a faucet, and the other end is a compressed nozzle 12. The compressed nozzle 12 corresponds to the brush 6, so that the cleaning liquid can be sprayed onto the brush 6 through the compressed nozzle 12 for brushing and cleaning.

[0035] Furthermore, the first connecting rod 9 is provided with several limiting slots 13, which can adjust the length of the first connecting rod 9 to meet the cleaning depth requirements of fermentation tanks of different sizes.

[0036] Furthermore, the end of the second connecting rod 10 is a threaded connection port 14, which allows for quick replacement of the brush 6 for cleaning residues of different hardness and viscosity.

[0037] Furthermore, a micro-perforated waterproof camera 15 is installed on the sleeve 5 to monitor the cleaning effect in real time.

[0038] Furthermore, the end of the air intake pipe 2 is connected to a compressed air source.

[0039] Furthermore, handles 3 are provided on both sides of the outer casing 8.

[0040] Furthermore, the hose 4 is a rubber hose or a PPR hose.

[0042] The fermentation tank cleaning device is used as follows: After installing a brush 6 of appropriate size and material according to the depth and size of the fermentation tank and the type of residue, adjust the length of the first connecting rod 9 and insert the cleaning device into the fermentation tank. Turn on the compressed air source and water tap, introduce gas through the air inlet pipe 2, start the pneumatic motor 1 and drive the first connecting rod 9 to rotate, which in turn guides the second connecting rod 10 via the gear 11, causing the brush 6 to rotate. Simultaneously, the cleaning solution is sprayed onto the brush 6 through the hose 4 and the compressed nozzle 12. While brushing and cleaning, the cleaning status is observed through the micro-perforated waterproof camera 15. After cleaning is complete, turn off the compressed air source and water tap, and remove the cleaning device.

[0043] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0044] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
