Description

TECHNICAL FIELD

[0001] The utility model relates to medicinal material processing technical field, concretely is a kind of pressure filter device for extracting Chinese herbal medicine. BACKGROUND

[0002] The production and processing of traditional Chinese medicine is a relatively complex process, as most of the traditional Chinese medicinal materials are crude drugs with plant tissues. In order to fully extract the medicinal liquid and effective components and avoid waste, sometimes the dregs of some medicinal materials need to be squeezed for extraction, so that the medicinal liquid remaining in the dregs can overflow.

[0003] To this end, Chinese patent number CN202322430681.2 discloses a pressure filter device for processing Chinese herbal medicine, which includes a vertically arranged filter cartridge. A filter plate is arranged inside the filter cartridge below. The filter plate has uniformly distributed through holes. A cover plate that can rotate freely horizontally is arranged at the upper end of the filter cartridge. A plurality of hydraulic rods are arranged at the bottom of the cover plate. The output ends of the hydraulic rods are connected to a pressing plate located directly above the filter plate. The pressing plate is gradually lowered by the hydraulic rods, thereby forcibly squeezing the dregs spread on the filter plate. Meanwhile, the short protruding columns can break and crush the dregs of larger volume for a second time and fill the gaps in the dregs. The squeezing effect on the dregs can be significantly improved by the cooperation of the pressing plate. Then the pressing plate rises, and the cover plate and the pressing plate are rotated horizontally by a servo motor, so that the short protruding columns can further fine-tune the squeezing position of the dregs. The dregs do not need to be stirred, and then they are squeezed for a second or multiple times, so that the dregs can be effectively squeezed and filtered, greatly improving the extraction efficiency of the dregs.

[0004] The device adjusts the squeezing position of the dregs by the rotation of the pressing plate and the short protruding columns. However, in actual use, due to the limited volume and rotation position of the short protruding columns, they cannot fully contact the top surface of the dregs, so the dregs cannot be fully squeezed and filtered, and a large amount of liquid remains in the dregs, causing waste and affecting the user experience.
