Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment, and in particular to a device and method for treating waste liquid in a cell freezing box. Background Art

[0002] The waste liquid from existing cell freezing boxes mainly includes metabolic waste generated during cell culture, cell fragments, and cryoprotectants used to freeze and preserve cells. If these waste liquids are not properly handled, they may pollute the environment, so appropriate treatment measures need to be taken. During the cell culture process, the culture liquid needs to be replaced regularly and the old culture liquid and washing liquid need to be removed. This step is called waste liquid suction. The existing waste liquid is pumped out by a water pump and discharged into a storage box for storage.

[0003] China's publicly authorized invention: CN207632822U discloses a waste liquid collection device for a cell room, which includes two suction cup hooks, a conveyor belt, and a waste liquid bucket. The conveyor belt is composed of two bent steel wires and a polyester film with a stainless steel sheet. The polyester film is connected between the two bent steel wires. A suction cup hook is fixed to the upper end of each of the two bent steel wires. The bottom ends of the two bent steel wires are fixed to the side of the upper end surface of the waste liquid bucket and form an inclined surface with the upper end surface of the waste liquid bucket. A stainless steel baffle with holes is provided in the middle of the waste liquid bucket. The device has a simple structure, can increase the amount of waste liquid collected, and can achieve solid waste and liquid waste separation during the waste liquid collection process, especially can reduce the risk of cell contamination. The device is simple and easy to operate, highly operable, and suitable for general use in laboratory cell rooms.

[0004] However, the device still has certain problems. In actual use, although the waste liquid can be filtered through the stainless steel baffle, the stainless steel baffle is fixed and not convenient for circulating swing filtration. The filter holes on the stainless steel baffle are easily blocked after long-term use, resulting in low filtration efficiency. At the same time, it is not convenient to quickly remove the stainless steel baffle to clean the solid waste on its surface. For this reason, we propose a cell freezing box waste liquid treatment device and method to solve the above problems. Summary of the invention
