Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a filtering device for a traditional Chinese medicine extraction tank, and belongs to the technical field of extraction tank accessory equipment and liquid medicine filtering equipment. Background Art

[0002] Chinese herbal formula granules are Chinese herbal granules made from Chinese herbal medicine slices through production processes such as extraction, concentration, drying and granulation. They have the characteristics of modern medicines while retaining the characteristics of traditional Chinese medicine. They are increasingly widely used in clinical practice of Chinese medicine.

[0003] The medicinal liquid obtained after the Chinese herbal medicine pieces are extracted in the extraction tank needs to be filtered before it can be concentrated. The existing extraction tank is equipped with a filter at the bottom of the tank to achieve preliminary filtration of the medicinal liquid, but in order to ensure that there is no residue in the medicinal liquid, it is usually necessary to connect an external filtering device to finely filter the medicinal liquid.

[0004] The patent with publication number CN211097787U discloses a filter for a Chinese herbal medicine extraction tank. The technical solution of the patent is to set a filter plate and a filter frame in the main body of the device to achieve the function of the filter plate for filtering large drug residues and the filter frame for fine filtering. However, in the actual filtering operation, as the drug solution flows, the drug residue is continuously deposited on the filter plate and the filter frame, thereby clogging the filter holes and reducing the filtering efficiency.

[0005] In summary, how to propose a filtering device to address the above technical issues has become an urgent problem to be solved by technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0023] Specific implementation method 1: Combination Figures 1 to 3 The present embodiment is described. A filtering device for a Chinese medicine extraction tank in the present embodiment includes a housing 100 , a frame 200 and a cage-type filtering unit 300 .

[0024] The box body 100 is mounted on the frame 200 , a driven shaft 110 is mounted on the box body 100 , an end cover 120 is mounted on one end surface of the box body 100 , a liquid inlet pipe 122 is mounted on the end cover 120 , and a liquid discharge pipe 123 is mounted on the bottom of the box body 100 .

[0025] A motor 210 is installed on the frame 200 , and pulleys are installed on the output shaft of the motor 210 and the driven shaft 110 . The motor 210 transmits power to the driven shaft 110 through belt transmission.

[0026] The cage filter unit 300 is installed in the housing 100, and the axis of the cage filter unit 300 is parallel to the horizontal plane. One end surface of the cage filter unit 300 is coaxially fixed to the driven shaft 110, and the other end surface of the cage filter unit 300 is against the end cover 120, and the inner surface of the cage filter unit 300 is connected to the liquid inlet pipe 122.

[0027] Specific implementation method 2: Combination Figures 1 to 3 To explain this embodiment, the cage-type filter unit 300 in this embodiment includes a circular plate 310 , an annular plate 320 , a sealing felt ring 321 , a filter screen 350 and a plurality of spacer sleeves 340 .

[0028] The circular plate 310 and the annular plate 320 are connected by bolts 330 . The spacer sleeve 340 is arranged between the circular plate 310 and the annular plate 320 , and the spacer sleeve 340 is sleeved on the bolts 330 .

[0029] The circular plate 310 is coaxially connected to the driven shaft 110 by screws. An annular groove is formed on one end surface of the annular plate 320. The sealing felt ring 321 is installed in the annular groove, and the two end surfaces of the sealing felt ring 321 are respectively against the bottom of the annular groove and the end cover 120.

[0030] The width of the filter screen 350 is greater than the length of the spacing sleeve 340 , and the filter screen 350 is fixedly connected to the outer circumferential surfaces of the circular plate 310 and the annular plate 320 .

In this way, when there are too many drug residues in the cage type filter unit 300, which affects the filtering effect of the cage type filter unit 300, the drug residues can be cleaned by removing the slag cleaning cover plate 121.

[0034] Furthermore, the slag cleaning cover plate 121 is made of organic glass, which makes it easy to observe the operating status of the cage-type filter unit 300.

[0035] The other components and connection relationships are the same as those of the first, second or third specific implementation modes.

[0036] How it works

[0037] Combination Figures 1 to 4 Explain the working principle of the utility model:

[0038] The motor 210 transmits power to the driven shaft 110 through a belt drive. One end face of the cage type filter unit 300 is coaxially fixed to the driven shaft 110, and the other end face of the cage type filter unit 300 is against the end cover 120. The axis of the cage type filter unit 300 is parallel to the horizontal plane, and the inner surface of the cage type filter unit 300 and the end cover 120 form a filtering space.

[0039] One end of the liquid inlet pipe 122 is connected to the Chinese medicine extraction tank, and the other end of the liquid inlet pipe 122 is connected to the inner surface of the cage-type filter unit 300. The medicinal liquid to be filtered in the Chinese medicine extraction tank is transported to the cage-type filter unit 300 through the liquid inlet pipe 122, and the rotation of the output shaft of the motor 210 drives the cage-type filter unit 300 to rotate.

[0040] A sealing felt ring 321 is installed in the annular groove on the annular plate 320, and the two end surfaces of the sealing felt ring 321 are respectively against the bottom of the annular groove and the end cover 120, so the drug liquid can only pass through the filter screen 350 and then be discharged from the box body 100 through the drain pipe 123, while the drug residue is intercepted by the filter screen 350.

[0041] During filtration, since the cage-type filter unit 300 rotates continuously, the drug residues in the cage-type filter unit 300 also move along the rotation direction, thereby preventing the drug residues from being deposited on the filter screen 350 and thus reducing the filtration efficiency.

[0042] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
