Description

Technical Field

[0001] The utility model relates to the field of microbial detection, in particular to a filtering device for microbial detection. Background Art

[0002] After searching Chinese patents, the announcement number is: CN208684950U, a filtering device for drug microbial limit detection, including a bracket, a round tube and a vacuum gauge, the round tube is arranged between the brackets, the vacuum gauge is arranged on the upper side of the round tube, and a vacuum adjustment button is arranged on one side of the vacuum gauge. The beneficial effect is that the utility model can adjust the vacuum degree in the round tube according to the viscosity of the liquid medicine through the pump adjustment button, vacuum gauge and vacuum adjustment button, so that the filtration efficiency of the liquid medicine can be accurately adjusted, and the liquid storage bottle is arranged to prevent the liquid medicine pumped out after filtration from entering the pump machine, ensuring the normal operation of the pump machine.

[0003] The existing filtering device is not convenient for replacing filter paper. Generally, filter paper is installed inside the fixed cylinder and is pressed and fixed by the bottom of the funnel. The funnel and the fixed cylinder are generally connected by threads. When replacing the filter paper, the funnel needs to be frequently turned. The whole replacement process is relatively cumbersome, which increases the workload and reduces the replacement efficiency. It also cannot prevent waste liquid from entering the vacuum pump. Generally, a waste liquid bottle is installed to collect waste liquid. During use, if the waste liquid bottle is full and is not discovered in time by the staff, the waste liquid will flow from the waste liquid bottle into the vacuum pump, causing damage to the vacuum pump and causing economic losses. In order to solve the above-mentioned problems, we propose a filtering device for microbial detection. Utility Model Content
