Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, in particular to a post-operation cleaning device for a bioreactor. Background Art

[0002] A photobioreactor refers to a type of device that can be used to culture photosynthetic microorganisms and their photosynthetic tissues or cells. This type of reactor has a similar structure to a general bioreactor. Under general conditions, a certain amount of light, temperature, and nutrients are required to culture the microorganisms and regulate and control the system environment. After the photosynthetic microorganism operation is completed, the photobioreactor needs to be cleaned to facilitate the next operation, so a cleaning device is required.

[0003] In the patent application with the authorization publication number CN113731992B and the authorization publication date 2021-12-31, entitled "A bioreactor post-operation cleaning device", the inner cleaning structure is provided to facilitate the cleaning of the inner wall of the bioreactor, so that the cleaning effect of the inner wall of the bioreactor is better; the outer cleaning structure is provided to facilitate the cleaning of the outer wall of the bioreactor, so that the cleaning effect of the outer wall of the bioreactor is better, and the outer cleaning structure is convenient for temporary placement to the side, does not hinder the replacement of workpieces, and is more flexible and convenient to use;

[0004] During the actual use of the above-mentioned device, the cleaning range is inconvenient to be adaptively adjusted according to the specifications of the actual bioreactor, resulting in low applicability. At the same time, the device scrapes the inner and outer walls of the bioreactor through the inner brush plate and the outer brush plate. This method is likely to cause scratches on the surface of the bioreactor. To avoid this, an additional cleaning liquid spraying device is required, which increases the operational burden. After the bioreactor is cleaned with the cleaning liquid, water droplets will be attached to the surface of the bioreactor. The presence of water droplets may provide an environment for the growth of microorganisms, which may easily affect the normal use of the bioreactor. Manual drying will increase the burden on the staff and be time-consuming and laborious.

[0005] Therefore, we propose a bioreactor post-operation cleaning device to solve the above-mentioned problems. Summary of the invention

The specific contents are as follows:

[0033] Start the electric push rod 1 to drive the tooth plate to move. The tooth plate drives the upper top plate to rotate by meshing with the stressed gear, so as to facilitate the bioreactor to be placed upside down and centered on the rubber pad 1. Then start the electric push rod 1 in the reverse direction to drive the upper top plate to rotate in the reverse direction. Then, the upper top plate is driven downward by the linear motion module until the rubber pad 2 is attached to the upper end surface of the bioreactor. Under the action of the upper and lower rubber pads 1 and 2, the bioreactor can realize the fixing operation of bioreactors of different specifications.

[0034] The motor at the end of the bevel gear transmission assembly is started to drive the threaded rod connected to the bevel gear transmission assembly to rotate, and the movable plate sleeved on the outer side of the threaded rod moves up and down under the action of the guide rod, thereby driving the cleaning mechanism on the movable plate to move up and down synchronously, so as to facilitate adaptive adjustment according to bioreactors of different heights, and the second electric push rod is started to drive the sliding plate to move, and then the driving motor is started, and the driving motor drives the bidirectional screw to rotate, and the outer vertical rod and the inner vertical rod threadedly sleeved on both ends of the bidirectional screw move relatively until the second scraper on the outer vertical rod and the inner vertical rod are respectively attached to the inner and outer walls of the bioreactor, so as to be suitable for bioreactors with different inner and outer diameters, and the motor at the end of the driving gear is started to drive the driving gear to rotate, and the driving gear drives the bioreactor above the gear ring to rotate by meshing with the gear ring, and the cleaning mechanism is used to clean the bioreactor during its rotation;

[0035] When the motor at the end of the driving gear drives the driving gear to rotate, the driving gear utilizes the meshing action with the gear ring and the driven gear to drive the gear ring and the driven gear to rotate synchronously. When the driving gear rotates forward, the driven gear utilizes the ratchet assembly to drive the turntable located below to rotate. After the turntable below rotates, the connecting rod between the piston plate inside the water transfer chamber drives the piston plate to reciprocate in the water transfer chamber, and the cleaning liquid in the cleaning liquid tank is drawn into the water transfer chamber, and then squeezed into the injection pipe located on the right side, and then sprayed out from the first nozzle, the second nozzle and the third nozzle. The first nozzle blows toward the surface of the second scraper to remove impurities adhered to the second scraper. The second nozzle blows toward the bioreactor so that the second scraper can scrape off the impurities on the bioreactor. The third nozzle blows between the two second scrapers to improve the cleaning effect.

[0036] When cleaning is completed, the motor at the end of the driving gear is started in reverse to drive the driving gear to rotate in the opposite direction. The driven gear uses the ratchet assembly to drive the turntable located above to rotate. When the turntable located above rotates, according to the above working principle, the gas transfer chamber filters and extracts external air, heats it through the heating element, and then squeezes it into the injection pipe located on the left, and then sprays it out from the first nozzle, the second nozzle and the third nozzle. At the same time, the driving gear drives the bioreactor to rotate in the opposite direction, so that the second scraper on the other side can scrape off the water droplets on the surface of the bioreactor. At the same time, since the hot air is sprayed from the first nozzle, the second nozzle and the third nozzle, the effect of removing the water droplets on the surface of the bioreactor can be improved.

At the same time, since the hot air is sprayed from the first nozzle 1161, the second nozzle 1162 and the third nozzle 1163, the effect of removing the water droplets on the surface of the bioreactor can be improved.

[0060] Working principle: When cleaning the device after using the bioreactor, Figure 1-11 As shown, firstly, the water transfer chamber 15 is connected to the injection pipe 116 and the cleaning liquid tank on the right side by a hose, and the gas transfer chamber 16 is connected to the injection pipe 116 on the left side by a hose, and then the upper top plate 6 is rotated by the flip cover mechanism 7 so that the bioreactor is placed upside down and centered, and then the bioreactor is fixed by the lower positioning mechanism and the upper positioning mechanism;

[0061] Then, the height adjustment mechanism 9 and the thickness adjustment mechanism 12 are used to adjust the position of the cleaning mechanism 11 until the scraper is attached to the inner and outer walls of the bioreactor, and then the motor at the end of the drive gear 3 is started to drive the bioreactor to rotate. During the rotation process, the scraper is used to clean the bioreactor;

[0062] During the rotation of the driving gear 3, the cooperation between the water vapor control mechanism 14 and the turntable 142 located below is used to drive the piston plate 17 to reciprocate inside the water transfer chamber 15, and the cleaning liquid in the cleaning liquid tank is sprayed out through the injection pipe 116 located on the right, and the contact effect of the scraper is cooperated to improve the cleaning effect. When the cleaning operation is completed, the motor at the end of the driving gear 3 is started in reverse to drive the driving gear 3 to rotate in the opposite direction, and the cooperation between the water vapor control mechanism 14 and the turntable 142 located above is used to drive the piston plate 17 to reciprocate inside the gas transfer chamber 16, and then the heated external gas is blown to the surface of the bioreactor to scrape off the water droplets on the surface of the bioreactor.
