Technical Field

[0001] The utility model relates to the technical field of biological preparation production, in particular to a filtering device for biological preparation production. Background Art

[0002] Biological preparations refer to drugs or other products produced by biotechnology, usually including substances extracted from organisms (such as bacteria, fungi, plants or animal cells) or produced by genetic engineering methods. These preparations can be used in many fields such as medicine, agriculture, and food industry. In the fermentation process of microbial or cell culture, it is necessary to separate the microbial cells, solid particles or other impurities in the fermentation liquid through a filtering device to extract the target product. At present, filtration is mostly performed by exchange filtration. However, when the existing filtering device filters the biological product liquid, the filtering surface of the device is ineffective, the product liquid is viscous, the product liquid has low passing efficiency, and the filter membrane needs to be replaced frequently, resulting in extremely low filtration efficiency of the biological product liquid. Therefore, the utility model proposes a filtering device for the production of biological preparations to solve the problems mentioned in the above background technology. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a filtering device for producing biological preparations.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Preferably, a cleaning spline is rotatably connected inside the product tank, and the product tank is connected to a lower discharge pipe.

[0007] Preferably, a motor is fixedly installed on the rear side of the collection box, and the motor output shaft is fixedly connected to the front rotating shaft. A bevel gear is fixed to the lower end of the cleaning spline, and another bevel gear meshing with the bevel gear at the lower end of the cleaning spline is fixed on the circumference of the rotating shaft.

[0008] Preferably, a notched round block located in the discharge pipe is fixed at the front end of the rotating shaft, and a through opening corresponding to the notch of the notched round block is opened inside the discharge pipe.

[0009] Preferably, the slide seat slides left and right in the collection box, the filter frame slides in the collection box through the front and rear slide seats, and an inclined block is fixed on the middle upper side of the slide frame, and shift blocks corresponding to the inclined block are fixed at the front and rear ends of the rotating shaft.

[0010] Preferably, the sliding frame slides left and right in the sliding seat, a stop block is fixed on the lower middle side of the sliding seat, and springs are connected between both sides of the stop block and the sliding frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The biological product liquid filtering structure provided in the utility model has a filtering surface provided with an inclined vibrating screen structure. When the product liquid flows down through the high side of the filtering surface, the high-frequency vibrating filter frame can accelerate the efficiency of the product liquid passing through the filtering surface.
