[0002] In the preparation process of traditional Chinese medicine, multiple processes such as crushing, extraction, concentration, spray drying and mixing and screening are required. The extraction of traditional Chinese medicine is a crucial link in the preparation of traditional Chinese medicine. In the extraction process, the solvent is mixed with the crushed traditional Chinese medicinal materials, so that the medicinal properties are extracted by the solvent. Since there are a large amount of medicinal dregs or other dirty particles in the extracted medicinal liquid, it is necessary to perform preliminary filtration treatment before concentration.

[0003] The existing filtering device mainly comprises a tank body, a coarse filter screen and a fine filter screen which are sequentially arranged in the tank body from top to bottom, a feed inlet is arranged at the top of the tank body, and a discharge outlet is arranged at the bottom of the tank body. During filtration, the medicinal liquid is injected from the feed inlet, the larger medicinal residues and particles are intercepted when passing through the coarse filter screen, the smaller medicinal residues and particles are intercepted when passing through the fine filter screen, and the filtered medicinal liquid is discharged from the discharge outlet.

[0004] Although the above filtering device can preliminarily filter the medicinal liquid, it is realized by relying on the gravity and the cooperation of the screen, the filtering efficiency is relatively low, and the filtering and separating effect of the medicinal liquid and the medicinal residues is poor, and some small medicinal residues are still mixed in the medicinal liquid.

The top cover 2 is provided with a feeding port 21, and the tank body 1 is provided with a discharging port 11 at a position close to the bottom. According to actual needs, valves for opening and closing can be installed at the feeding port 21 and the discharging port 11.

[0036] The tank body 1 has a hollow structure and is open at the top, is made of stainless steel material, and has high strength and excellent corrosion resistance. More specifically, the tank body 1 comprises a side wall and a bottom wall, and the inner surface of the bottom wall is fixedly connected with a flow guide platform 12 which gradually decreases in height from the middle to the periphery to form a slope surface on which the falling liquid can converge towards the side wall. A bottom plate 7 is placed below the tank body 1, and the tank body 1 is fixed to the bottom plate 7 by supporting legs 13.

[0037] Referring to Figure 2 The top cover 2 is also made of stainless steel material and is threadedly connected or flange-connected to the open end of the tank body 1, which is only shown in the figure and is not specifically illustrated. One side of the top cover 2 with the feeding port 21 is fixedly connected with a handle 22 to facilitate the opening and closing operation of the staff.

[0038] The filter basket 5 is hollow and open at the top end, and has a barrel-shaped structure which is large at the top and small at the bottom. Filter holes are formed on the filter basket 5, and when the top cover 2 is installed on the tank body 1, the filter holes of the filter basket 5 are located below the upper edge of the sieve cylinder 3.

[0039] Referring to Figure 2 and Figure 3 A plurality of clamping plates 51 are integrally formed on the open end of the filter basket 5 and extend in the radial direction of the open end of the filter basket 5. Meanwhile, a mounting seat 8 for mounting the filter basket 5 is fixedly connected to one side of the top cover 2 facing the tank body 1. The mounting seat 8 has an L-shaped cross section and specifically comprises a fixing ring 81 and a supporting ring 82 fixedly connected to one end of the fixing ring 81. One end of the fixing ring 81 away from the supporting ring 82 is fixedly connected to the top cover 2, so that a clamping groove is formed between the supporting ring 82 and the top cover 2. The clamping groove is matched with the clamping plates 51, and a plurality of gap notches 83 are formed on the supporting ring 82 and correspond to the clamping plates 51 one by one.

[0040] During installation, the clamping plates 51 are aligned with the gap notches 83 and are inserted, and then the filter basket 5 is rotated so that the clamping plates 51 are turned into the clamping groove and are misaligned with the gap notches 83.

[0041] In order to facilitate the staff to install the filter basket 5, a plurality of protrusions 52 for easy gripping are fixedly connected to the lower position of the filter basket 5.

[0042] The inside of the sieve cylinder 3 is hollow and one end is open, the sieve cylinder 3 is located directly below the filter basket 5 and the open end of the sieve cylinder 3 is half wrapped in the filter basket 5, so that the medicine liquid filtered by the filter basket 5 can directly enter the sieve cylinder 3. The side wall of the sieve cylinder 3 is processed with dense filter holes for filtered medicine liquid to pass through. The bottom plate 7 is not processed with filter holes, and such arrangement is also convenient for the medicine liquid to converge to the side wall. The center of the sieve cylinder 3 far from the open end is fixed with a rotating shaft 31, the rotating shaft 31 is rotatably connected to the bottom wall of the tank body 1 through a shaft sealing structure, and the rotating shaft 31 penetrates through the tank body 1 to the outside, and a corresponding flow guide table 12 is processed with a vertical through hole matched with the rotating shaft 31.

[0043] The filter cloth 4 is made of polyester, polypropylene or nylon material, and has a cylindrical structure as a whole. The filter cloth 4 is arranged in close contact with the inner wall of the sieve cylinder 3 and has a permeation function. Magnets are sewn at the bottom and the top of the filter cloth 4. The filter cloth 4 can be fixed in the sieve cylinder 3 by the magnets.

[0044] Referring to Figure 2 The driving assembly 6 is arranged on the bottom plate 7 below the tank body 1 and specifically includes a motor 61 fixed on the bottom plate 7, a driving gear 62 mounted on the output shaft of the motor 61, and a driven gear 63 fixed on the rotating shaft 31 and engaged with the driving gear 62. The size of the driving gear 62 is larger than that of the driven gear 63. In order to protect the components, a protective cover 9 is arranged outside the driving assembly 6.

[0045] The implementation principle of the embodiment of the present application is as follows: in operation, the motor 61 is started to drive the sieve cylinder 3 to rotate at high speed, and the medicine liquid is injected from the feed inlet 21. In the process of injection, the filter basket 5 performs primary filtration on the medicine liquid to intercept large particles and dregs in the medicine liquid in the filter basket 5, and the medicine liquid enters the sieve cylinder 3. Since the sieve cylinder 3 rotates at high speed, the medicine liquid quickly penetrates the filter cloth 4 and the sieve cylinder 3 into the tank body 1 under the action of centrifugal force to achieve secondary filtration, and finally is discharged from the discharge outlet 11. The fine residues and particles in the medicine liquid are intercepted in the filter cloth 4. Compared with the traditional filter device, the present application adopts two-stage filtration and centrifugal processing to greatly improve the filtration efficiency and the separation effect of the medicine liquid and the dregs by using the fine filtration of the filter cloth 4.
