Description

Technical Field

[0001] The utility model relates to the technical field of reactor cleaning, in particular to a lifting cleaning device for a biological reactor. Background Art

[0002] Bioreactors are equipment used for biological / cell culture, reacting and synthesizing microorganisms with chemical solutions to achieve the heating, evaporation, cooling, and low-speed mixing functions required by the process. However, when the reactor produces viscous products, raw materials will remain on the side walls of the reactor. The residual materials will affect the quality of the next batch of products. In order to ensure the stability of product quality, the reactor needs to be cleaned using a cleaning device after the completion of the next batch of products.

[0003] Application No. 202321922524.7 discloses a liftable reactor cleaning device, "a plurality of universal wheels are symmetrically fixedly installed on the bottom of the mounting frame, a rotary joint is fixedly installed on the water outlet end of the telescopic tube, the water outlet end of the rotary joint is fixedly connected to the water inlet end of the flushing pipe, and the device is moved by the provided universal wheels." In the above, the movement of the device is achieved by rolling the universal wheels to move it to the side of the reactor to be cleaned, but the wheel body of the universal wheel is a cylindrical structure, which reduces its contact area with the ground, and easily leads to poor stability when the device is placed, and vibrations will be generated during the cleaning process. Relying solely on the universal wheel for support will cause the device to shake during the cleaning process, thereby affecting the cleaning of the reactor and resulting in incomplete cleaning of the reactor.

The water box is connected to the lower end of the connecting plate through a short block, and the connecting pipe is connected to the outer wall of the water box, and the water inlet end of the connecting pipe passes through the connecting plate and is connected to the end of the hose away from the delivery pipe. Several of the nozzles are equidistant and evenly connected to the lower end surface of the water box.

[0008] Specifically, when cleaning the reactor, first, the connecting plate is driven down by the first electric telescopic rod to enable the cleaning component to enter the interior of the reactor. After entering, the brush strips and scraper on the outer wall of the cylindrical barrel contact the inner wall of the reactor. Then the driving motor of the driving component is turned on, and the driving motor runs in conjunction with the rotating shaft to drive the connecting rod and the cylindrical barrel to rotate, so that the brush strips and scraper rotate with the rotation of the cylindrical barrel. The residue on the inner wall of the reactor can be scraped off by the scraper, and then the inner wall of the reactor is cleaned by the brush strip. At the same time, the water pump of the pumping component is operated to cooperate with the water pipe, the delivery pipe and the smooth hose to pump water into the interior of the water spray component. The water in the hose enters the water box through the connecting pipe, and is finally sprayed out through the nozzle to flush the inner wall of the reactor to cooperate with the cleaning operation and complete the cleaning operation of the reactor.
