Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material processing, in particular to an impurity removal and screening device. Background Art

[0002] Screening is required during the processing of Chinese medicinal materials. Traditional screening devices use electric vibrating screens for screening. During screening, the separation degree between Chinese medicinal materials and impurities is insufficient, which affects the screening effect.

[0003] Prior art CN216910934U discloses a device for processing and screening impurities for Chinese medicinal materials. The device comprises a screening tank housing, within which a screening drum, a screening plate, and a dust-blowing device are installed. Specifically, the screening drum is cleverly equipped with an inlet and outlet pipes at each end. In operation, after the Chinese medicinal materials are introduced into the inlet pipe, a drive mechanism is activated, which drives the outlet pipe and the screening drum to work in tandem, gradually expanding the inner diameter of the drum from left to right. This design ensures that once the Chinese medicinal materials enter the screening drum, they move smoothly and slowly to the right, completing the screening process. Simultaneously, the dust-blowing device effectively extracts and removes dust from the Chinese medicinal materials. After screening, qualified Chinese medicinal materials are discharged smoothly through the outlet pipe. The screening plate effectively isolates impurities and smaller medicinal materials, discharging them separately through two separate drop pipes, significantly improving the quality of the medicinal materials produced.

[0004] The above device can perform graded screening, but during the screening process, screening is only performed by rotating the screening cylinder, so that Chinese medicinal materials are easily accumulated in the screening cylinder, resulting in affecting the screening effect.

The complete gear 108 rotates, thereby driving the rotating gear 107 to rotate periodically, so that the rotating gear 107 drives the rotating shell 104, the outer cylinder 105 and the inner cylinder 106 to rotate, so that the outer cylinder 105 and the inner cylinder 106 can rotate back and forth under the action of gravity and the incomplete gear 108, so that the Chinese medicinal materials in the inner cylinder 106 and the outer cylinder 105 are distributed more evenly to avoid accumulation. It can be understood that the above scheme can be used to improve the screening effect of Chinese medicinal materials, and can also be used to increase the time for Chinese medicinal materials to be screened in the outer cylinder 105 and the inner cylinder 106.

[0023] According to this specific embodiment, the collecting frame 102 is installed at the bottom of the housing 101 . The collecting frame 102 is connected to the housing 101 by bolts, and the screened impurities are collected by the collecting frame 102 .

The incomplete gear 108 is rotatably connected to the outer shell 101 and meshes with the rotating gear 107 and is located on one side of the outer shell 101. The driving member 109 is provided on the rotating shell 104 and drives the outer cylinder 105 to rotate. The side walls of the inner cylinder 106 and the outer cylinder 105 are The inclined surface is provided with a plurality of sieve holes evenly thereon, wherein the diameter of the sieve holes on the outer cylinder 105 is smaller than the diameter of the sieve holes on the inner cylinder 106, and the length of the inner cylinder 106 is greater than the length of the outer cylinder 105, so that it is convenient for the staff to classify and collect the Chinese medicinal materials of different sizes screened out; the outer shell 101 is also provided with a motor seat 119, and a rotating motor 120 is installed on the motor seat 119, and the output end of the rotating motor 120 is connected to the incomplete gear 108; when in use, the Chinese medicinal materials to be screened are placed inside the inner cylinder 106, and then the driving member 109 is started to drive the outer cylinder 105 to rotate, thereby driving the inner cylinder 106 to rotate, and the Chinese medicinal materials inside thereof are driven by the rotation of the inner cylinder 106 The Chinese medicinal materials rotate, and then the Chinese medicinal materials are screened, so that impurities and Chinese medicinal materials with smaller volumes are discharged through the sieve holes on the inner cylinder 106 and then fall into the inner side of the outer cylinder 105. Then, the Chinese medicinal materials are screened for the second time by the outer cylinder 105, so that impurities fall into the collection frame 102 for collection. Since the sizes of the sieve holes on the inner cylinder 106 and the outer cylinder 105 are different, the sizes of the Chinese medicinal materials screened out by the inner cylinder 106 and the outer cylinder 105 are different. During the screening process, the rotating motor 120 is started to drive the incomplete gear 108 to rotate.

Since the feed pipe 111 can be bent, the feed pipe 111 can be prevented from interfering with the swing of the inner cylinder 106. At the same time, Chinese medicinal materials are added through the feed hopper 110, so that the Chinese medicinal materials enter the inner cylinder 106 along the feed pipe 111, which is convenient for the staff to add Chinese medicinal materials to the inner cylinder 106.
