Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0028] The present invention provides as Figures 1-6A crusher for the production of ursodeoxycholic acid preparations is shown, including a crushing cylinder 1. A connecting pipe 2 is connected to the center of the rear end of the crushing cylinder 1. A hopper 3 is connected to the upper end of the connecting pipe 2. A collection box 4 is fixedly connected to the lower end of the crushing cylinder 1. Support legs 5 are fixedly connected to the four corners of the lower end of the collection box 4 for supporting the crushing cylinder 1 and the collection box 4. A limiting frame 6 is fixedly connected to the inner part of the front end of the connecting pipe 2. A limiting connection cover 7 with an opening forward is fixedly connected to the inner part of the front end of the crushing cylinder 1. The limiting frame 6 and the limiting connection cover 7 are used for restricting the position of the crushing rotating shaft 9. A fixing frame 8 is fixedly connected to the inner part of the front end of the limiting connection cover 7 for fixing the crushing motor 11. The front end of the limiting frame 6 is rotatably connected to a crushing rotating shaft 9, and the front end of the crushing rotating shaft 9 passes through the inner parts of the centers of the limiting connection cover 7 and the fixing frame 8 from front to back. A plurality of primary crushing roller plates 10 are fixedly connected to the outer rear side of the crushing rotating shaft 9. A crushing motor 11 is arranged at the front end of the crushing rotating shaft 9, and the front end of the crushing rotating shaft 9 is rotatably connected to the inner part of the center of the rear end of the crushing motor 11. The crushing motor 11 is fixedly connected to the front end of the fixing frame 8. A crushing filter cylinder 13 is rotatably connected between the inner walls of the front and rear ends of the crushing cylinder 1 through two limiting rotating rings 12, and the two limiting rotating rings 12 are respectively fixedly connected to the outer parts of the centers of the inner walls of the front and rear ends of the crushing cylinder 1. The crushing filter cylinder 13 is sleeved outside a plurality of primary crushing roller plates 10, and the front end of the crushing filter cylinder 13 is sleeved outside the limiting connection cover 7. A plurality of primary filter holes 14 are opened in the inner part of the cylindrical outer wall of the crushing filter cylinder 13. A plurality of secondary crushing roller plates 20 are fixedly connected to the outer part of the cylindrical outer wall of the crushing filter cylinder 13. A plurality of secondary filter holes 21 are opened in the inner part of the lower end of the crushing cylinder 1. The ursodeoxycholic acid raw material is put into the hopper 3 and introduced into the crushing filter cylinder 13 arranged at the center of the inner part of the crushing cylinder 1 through the connecting pipe 2. The crushing cylinder 1 performs primary crushing through a plurality of primary crushing roller plates 10 arranged inside. The raw material after primary crushing is introduced between the crushing cylinder 1 and the crushing filter cylinder 13 through a plurality of primary filter holes 14 and undergoes secondary crushing through a plurality of secondary crushing roller plates 20. Finally, it is introduced into the collection box 4 through a plurality of secondary filter holes 21 opened in the inner part of the lower end of the crushing cylinder 1 for collection and export, so as to obtain the ursodeoxycholic acid raw material powder, and the ursodeoxycholic acid preparation is made with the ursodeoxycholic acid raw material powder.
[0029] Among them, a plurality of extrusion balls are placed inside the gaps between the multiple first-stage crushing roller plates 10 and inside the gaps between the multiple second-stage crushing roller plates 20. The multiple first-stage crushing roller plates 10 are fixedly connected to the outside of the crushing rotating shaft 9. The crushing rotating shaft 9 is driven to rotate by a crushing motor 11 provided at the front end. When the crusher performs first-stage crushing on the ursodeoxycholic acid raw material, the multiple first-stage crushing roller plates 10 rotate inside the crushing filter cylinder 13, causing the multiple extrusion balls to roll back and forth inside the gaps between the multiple first-stage crushing roller plates 10. At the same time, the multiple first-stage crushing roller plates 10 can scrape the raw material into the gaps through the edges. After the raw material enters the gaps, it will be rolled back and forth by the extrusion balls, so that the ursodeoxycholic acid raw material is crushed. And when the diameter of the crushed ursodeoxycholic acid raw material is smaller than the pore diameter of the first-stage filter holes 14, the crushed ursodeoxycholic acid raw material will enter the space between the crushing cylinder 1 and the crushing filter cylinder 13 through the first-stage filter holes 14 for second-stage crushing.
[0030] Preferably, a tooth groove 15 is provided inside the front side of the cylindrical inner wall of the crushing filter cylinder 13. A driven gear 16 is rotatably connected to the inside of the lower end of the tooth groove 15. An upper end of the driven gear 16 is rotatably connected to a driving gear 17. The driving gear 17 is fixedly connected to the outside of the crushing rotating shaft 9. The driving gear 17 is rotatably connected inside the limit connection cover 7 and is located behind the fixed frame 8. The driven gear 16 is connected between the tooth groove 15 and the driving gear 17 through a gear groove 18. The gear groove 18 is provided inside the inner wall of the lower end of the limit frame 6. During the process of first-stage crushing, the crushing motor 11 drives the multiple first-stage crushing roller plates 10 to rotate through the crushing rotating shaft 9, and drives the crushing filter cylinder 13 to rotate in the opposite direction to the first-stage crushing roller plates 10 through the tooth groove 15, the driven gear 16 and the driving gear 17, so that the ursodeoxycholic acid raw material inside the crushing filter cylinder 13 can more easily enter the gaps between the multiple first-stage crushing roller plates 10. At the same time, it can turn the ursodeoxycholic acid raw material, making it easier for the crushed ursodeoxycholic acid raw material with a diameter smaller than the pore diameter of the first-stage filter holes 14 to pass through the inside of the first-stage filter holes 14, thereby improving the crushing efficiency of the ursodeoxycholic acid raw material and at the same time improving the crushing uniformity.
[0031] Preferably, since the driven gear 16 is rotatably connected to the inside of the gear groove 18 through a gear seat 19, and the rear end of the gear seat 19 is fixedly connected to the lower side of the center of the rear inner wall of the limit connection cover 7, the upper and lower ends of the driven gear 16 are respectively engaged with the tooth groove 15 and the driving gear 17. Therefore, the driving gear 17 can drive the crushing filter cylinder 13 to rotate in the opposite direction to the first-stage crushing roller plates 10 through the driven gear 16.
[0032] Preferably, after the Ursodeoxycholic Acid raw material enters the inside of the crushing cylinder 1 and the crushing filter cylinder 13, multiple secondary crushing roller plates 20 rotate between the crushing cylinder 1 and the crushing filter cylinder 13 driven by the crushing filter cylinder 13, and scrape the Ursodeoxycholic Acid raw material into the gap between the multiple secondary crushing roller plates 20 through the edge for secondary crushing. The Ursodeoxycholic Acid raw material entering the gap is crushed again under the rolling pressure of multiple extrusion balls. When the diameter of the Ursodeoxycholic Acid raw material is smaller than the aperture of the secondary filter hole 21, the Ursodeoxycholic Acid raw material will enter the inside of the collection box 4 through the secondary filter hole 21. The collection box 4 collects the Ursodeoxycholic Acid raw material with the crushing fineness reaching the standard, and finally exports it through the export pipe at the lower end. Since the aperture of the secondary filter hole 21 is smaller than the aperture of the primary filter hole 14, the Ursodeoxycholic Acid raw material entering the inside of the collection box 4 is finer than the Ursodeoxycholic Acid raw material entering between the crushing cylinder 1 and the crushing filter cylinder 13. Through primary and secondary crushing, the Ursodeoxycholic Acid raw material meets the preparation standard.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
