Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing equipment, in particular to a root medicinal material screening drum. Background Art

[0002] For root medicinal materials, it is inevitable that soil will adhere to and remain on the roots during the processing. If it is not removed, it will greatly affect the quality of the medicinal materials. In order to remove the soil attached to the root medicinal materials, pharmaceutical factories generally use vibrating screening machines or drum screening machines for batch processing. The working principle of the drum screening machine is as follows: the screening drum is arranged obliquely on the rotating drive mechanism, and the rotating drive mechanism drives the screening drum to rotate. After the root medicinal materials enter from one end of the screening drum, the soil falls through the screen, and the root medicinal materials are discharged along the other end of the screening drum, thereby achieving screening. However, during the working process of the existing drum screening machine, it can only screen and remove the soil mixed in the root medicinal materials, but it has little effect on removing the soil remaining on the root medicinal materials. Utility Model Content

[0003] The purpose of the utility model is to provide a root medicinal material screening drum in view of the existing technical status. On the basis of screening out the mixed soil, the utility model can not only better remove the residual soil on the root medicinal materials, but also can quickly complete disassembly and assembly, and is convenient for cleaning and maintenance.

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 3 As shown, a root medicinal material screening drum includes a drum frame 1 and a screen 2 coated on the drum frame 1. After the root medicinal materials enter from one end of the screening drum, the soil mixed therein falls through the screen 2, and the root medicinal materials are discharged along the other end of the screening drum, thereby achieving screening out of the soil mixed in the root medicinal materials.

[0023] The drum frame 1 includes two identical frames, which include a first annular body 3, a second annular body 4 and a plurality of connecting rods 5. The first annular body 3 and the second annular body 4 have the same outer diameter, and the connecting rods 5 are connected between the first annular body 3 and the second annular body 4. A first support frame 6 is provided in the inner ring of the first annular body 3, and the first support frame 6 is provided with a first connecting hole 6-1 at the center of the first annular body 3. The second annular body 4 is evenly provided with a plurality of second connecting holes 4-1 along its circumference. The two frames are spliced ​​into the drum frame 1 through the second connecting holes 4-1 provided on the second annular body 4 and locking members (generally bolts, not shown in the figure). The first connecting holes 6-1 are used to connect the spliced ​​drum frame 1 to the rotating drive mechanism.

[0024] In the above technical solution, the thickness of the first annular body 3 is greater than the thickness of the second annular body 4. After the two frames are spliced ​​into the drum frame 1, the first annular bodies 3 at both ends of the drum frame 1 are connected to the rotary drive mechanism, so the thickness of the first annular body 3 should be as large as possible to bear a larger load, and the thickness of the second annular body 4 does not need to be too large.

[0025] In this embodiment, illustratively, four connecting rods 5 are connected between the first annular body 3 and the second annular body 4 .

[0026] The frame body is provided with a third annular body 7 connected to its connecting rod 5, and the third annular body 7 is welded and fixed in the frame body, and along the axial direction of the frame body, the third annular body 7 is arranged in the middle of the frame body. A second support frame 8 is provided in the third annular body 7, and the second support frame 8 divides the inner ring of the third annular body 7 into 2N sector-shaped areas evenly, and baffles 9 are alternately arranged in the sector-shaped areas of the third annular body 7, and the baffles 9 are detachably fixed on the second support frame 8 provided in the third annular body 7.

[0027] In the above technical solution, on the axial projection surface of the drum frame 1, the baffles 9 provided in the third annular bodies 7 of the two frame bodies do not overlap to prevent the root medicinal materials from running poorly in the screening drum; one end of the drum frame 1 is the feed end and the other end is the discharge end, and the baffle 9 is provided with reinforcing ribs on the end surface in the direction from the feed end to the discharge end to strengthen the structural strength of the baffle 9 and prevent the root medicinal materials from impacting it and causing excessive deformation. The shape of the reinforcing ribs is determined according to the reinforcement requirements.

[0028] In this embodiment, illustratively, the second support frame 8 evenly divides the inner ring of the third annular body 7 into 4 or 6 sector-shaped areas.

[0029] In addition, it should be noted that the screen 2 should be respectively coated on the two frame bodies of the drum frame 1, rather than being entirely coated on the entire drum frame 1, which is more conducive to the disassembly and assembly of the screening drum.

[0030] In general, the utility model designs the drum frame 1 to be composed of two identical frame bodies, and at the same time, a third ring body 7 is added in each frame body, and baffles 9 are alternately arranged in the third ring 7. In the process of the root medicinal materials sliding from the feed end to the discharge end of the screening drum, they will collide with the baffles 9, thereby removing the residual soil thereon, and at the same time, a hoarding trend will be formed at the baffles 9. As the screening drum rotates, the root medicinal materials that have formed a hoarding trend will also fall and collide, thereby further removing the residual soil thereon.

[0031] According to the above design, on the basis of achieving screening out mixed soil, the utility model can not only better remove the soil remaining on the root medicinal materials, but also can quickly complete disassembly and assembly, and is convenient for cleaning and maintenance.

[0032] Of course, the above are only preferred implementations of the present utility model, and are not intended to limit the scope of use of the present utility model. Therefore, any equivalent changes made to the principles of the present utility model should be included in the protection scope of the present utility model.
