[0002] Cyanuric acid is an organic compound, which is one of the isomers of uric acid. In the chemical industry, cyanuric acid can be used as a raw material for dyes, pigments and fluorescent brighteners. In the medical field, it is sometimes used to prepare some drugs. It can also be used to produce pesticides and herbicides. Cyanuric acid products are crystalline solids. In order to adapt to the use in various different fields in the later stage, cyanuric acid needs to be crushed after production.

[0003] Most traditional crushing devices directly extrude solid cyanuric acid to crush the crystalline cyanuric acid. The cyanuric acid particles obtained by this crushing method generally have large differences in particle diameter, which cannot meet the requirements for use in some fields. Therefore, it is necessary to control the diameter of the crushed cyanuric acid particles. In addition, the diameters of cyanuric acid particles used in different fields are also different. The existing crushing devices cannot limit the diameter of cyanuric acid particles during the crushing process. Therefore, a crushing device for cyanuric acid production that can adjust the diameter of the crushed particles is needed. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-Figure 3 The specific implementation methods of the utility model are further described in detail:

[0019] Embodiment 1, by Figure 1-Figure 3It is provided, comprising: a support platform 1, with a plurality of legs 2 fixedly connected to the bottom thereof, preferably three or more legs 2, to ensure that the support platform 1 can be stably placed on a plane, and the shape of the support platform 1 can be adjusted according to demand, and the number of legs 2 can be adjusted synchronously. A circular sleeve 3 is fixedly connected to the support platform 1. A material storage groove 4 is fixedly connected to the circular sleeve 3, and a discharge port 5 is provided at the bottom to discharge the material after crushing from the crushing area. A fixed friction plate 6 is fixedly connected to the material storage groove 4, and a feed port 7 is provided at the top thereof. The middle part of the fixed friction plate 6 is in a truncated cone shape, and a plurality of protrusions are provided on the inner side of the fixed friction plate 6 to facilitate material crushing. The top of the feed port 7 is in a trumpet shape to facilitate the placement of materials. When in use, the material to be crushed is placed into the fixed friction plate 6 through the feed port 7. The rotating friction plate 8 is placed inside the fixed friction plate 6, and its bottom is arranged inside the material storage groove 4. A conveying pipe 9 is fixedly connected in the middle. The conveying pipe 9 is a hollow pipe-mounted structure. A screw 10 is rotatably connected in the middle of the conveying pipe 9. The screw 10, the conveying pipe 9, the rotating friction plate 8, the fixed friction plate 6 and the material storage groove 4 are all coaxial. When in use, the rotating friction plate 8 rotates relative to the fixed friction plate 6 to squeeze and crush the material placed between the rotating friction plate 8 and the fixed friction plate 6. Since the middle part of the fixed friction plate 6 is truncated, the frictionally crushed material will slide along the inclined surface into the material storage groove 4, and then be discharged from the material storage groove 4 through the discharge port 5. The annular frame 11 is placed inside the material storage groove 4 and slides in the vertical direction relative to the material storage groove 4. The top contacts the rotating friction plate 8. The position of the annular frame 11 can change the gap between the rotating friction plate 8 and the fixed friction plate 6 by adjusting the position of the annular frame 11 up and down, thereby changing the particle diameter of the material after crushing. The discharge pipe 12 is placed at the bottom of the material storage groove 4 and is connected to the discharge port 5. The bottom of the conveying pipe 9 passes through the top of the discharge pipe 12. The auger 10 passes through the discharge pipe 12, and a sieve plate 13 is fixedly connected to the bottom thereof. The sieve plate 13 is connected to the discharge pipe 12 by bolts. The density of the sieve plate 13 can be replaced and adjusted according to needs. The sieve plate 13 is at an angle to the horizontal plane. A discharge plate 14 is fixedly connected to the bottom of the discharge pipe 12, and the sieve plate 13 is placed between the discharge pipe 12 and the discharge plate 14. When in use, the crushed material slides through the sieve plate 13 to the side close to the auger 10. At the same time, the crushed particles with a diameter smaller than the diameter of the holes in the sieve plate 13 penetrate the sieve plate 13 and enter the upper side of the discharge plate 14, and then slide out of the discharge plate 14. At the same time, the material with a larger diameter enters the bottom of the auger 10, and then is pushed by the auger 10 along the conveying pipe 9 to the upper end of the rotating friction plate 8, and then undergoes secondary crushing.

[0020] The invention also includes a plurality of limit screws 15 rotatably connected to the bottom of the material storage groove 4. The top of the limit screw 15 is gear-shaped, and the outer side of the remaining part is provided with a thread. The plurality of limit screws 15 are evenly distributed along the bottom of the material storage groove 4. The outer side of each limit screw 15 is provided with a positioning sleeve 16. Each positioning sleeve 16 is threadedly connected to the corresponding limit screw 15. The diameter pitch of the limit screw 15 and the positioning sleeve 16 is small. In actual use, there is no human operation and the limit screw 15 will not rotate. Each positioning sleeve 16 is fixedly connected to the annular frame 11. The outer side of the annular frame 11 is provided with a drive ring 17. A handle is fixedly connected to one side of the drive ring 17. The handle passes through the circular sleeve 3. The drive ring 17 corresponds to each of the limit screws 15. The screws 15 are all in the shape of internal gears, and each of the limit screws 15 is meshed with a drive ring 17, which is rotatably connected to the arc sleeve. A plurality of support wheels 25 are rotatably connected to the top of the annular frame 11, and each of the support wheels 25 is in contact with the rotating friction plate 8. One side of the support wheel 25 is an inclined surface, so that the rotating friction plate 8 can run smoothly when rotating relative to the annular frame 11. At the same time, a bearing can be installed at the axial position of the support wheel 25. When in use, the plurality of limit screws 15 are rotated synchronously by rotating the drive ring 17. At the same time, the limit screw 15 adjusts the position of the annular frame 11 relative to the arc sleeve through the positioning sleeve 16. At this time, the support wheel 25 changes the gap between the rotating friction plate 8 and the fixed friction plate 6, thereby changing the diameter of the finished crushed material.

[0021] The support platform 1 also includes a driving motor 18 fixedly connected to the middle part thereof. When in use, the driving motor 18 needs to be powered on and the control switch is turned on. The output shaft of the driving motor 18 is fixedly sleeved with a first driving gear 19 and a second driving gear 20. The outer side of the conveying pipe 9 is fixedly sleeved with a first driven gear 21, and the first driven gear 21 is meshed with the first driving gear 19. The bottom of the auger 10 is fixedly connected with a second driven gear 22, and the second driven gear 22 is meshed with the second driving gear 20. The diameter of the first driving gear 19 is smaller than that of the first driven gear 21. The first driven gear 21 has a larger tooth height than the first driven gear 21 to ensure that the first driven gear 21 always keeps in mesh with the first driving gear 19 during the up and down sliding process of the rotating friction plate 8. The diameter of the second driving gear 20 is smaller than the second driven gear 22 to ensure that the rotating friction plate 8 rotates while the auger 10 rotates in the same direction, and the auger 10 rotates relative to the conveying pipe 9. When in use, the driving motor 18 is started. At this time, the first driving gear 19 and the second driving gear 20 respectively rotate the rotating friction plate 8 and the auger 10 through the first driven gear 21 and the second driven gear 22.

[0022] Embodiment 2, based on embodiment 1, Figure 1-Figure 3It is given that a plurality of friction strips 23 are fixedly connected to one side of the rotating friction plate 8, and the friction strips 23 are used to optimize the crushing effect. The friction strips 23 are placed between the rotating friction plate 8 and the fixed friction plate 6. When in use, the friction strips 23 contact with the material and generate friction. At the same time, the material is squeezed and crushed by the rotating friction plate 8 and the fixed friction plate 6. A plurality of push plates 24 are fixedly connected to the peripheral side of the rotating friction plate 8, and the push plates 24 are placed in the material storage groove 4. When in use, the push plates 24 push the crushed material falling into the material storage groove 4 to the position of the discharge port 5, so that the material is discharged from the discharge port 5 to avoid material blockage.

[0023] The working process of the utility model is as follows: when in use, a container for storing crushed materials is placed under the discharge plate 14, and a screen with an appropriate aperture is selected and installed, and then the drive motor 18 is started. At this time, the first drive gear 19 and the second drive gear 20 respectively rotate the rotating friction plate 8 and the auger 10 through the first driven gear 21 and the second driven gear 22, and then the material to be crushed is placed in the fixed friction plate 6 through the feed inlet 7. At this time, the rotating friction plate 8 rotates relative to the fixed friction plate 6, and the material placed between the rotating friction plate 8 and the fixed friction plate 6 is squeezed and crushed. Since the middle part of the fixed friction plate 6 is in the shape of a truncated cone, the friction strip 23 contacts the material and generates friction. At the same time, the material is squeezed and crushed by the rotating friction plate 8 and the fixed friction plate 6. The frictionally crushed material will slide into the storage groove 4 along the inclined surface, and the push plate 24 will fall into the crushed material in the storage groove 4. The material is pushed to the discharge port 5 so that the material is discharged from the discharge port 5 to avoid material blockage. The crushed material slides through the sieve plate 13 to the side close to the auger 10. At the same time, the crushed particles with a diameter smaller than the diameter of the holes in the sieve plate 13 penetrate the sieve plate 13 and enter the upper side of the discharge plate 14, and then slide out of the discharge plate 14 and enter the container for storing the crushed material. At the same time, the material with a larger diameter enters the bottom of the auger 10, and then the auger 10 pushes it to the upper end of the rotating friction plate 8 along the conveying pipe 9, and then performs secondary crushing. When it is necessary to adjust the diameter of the crushed material, the multiple limit screws 15 are rotated synchronously by rotating the drive ring 17. At the same time, the limit screw 15 adjusts the position of the annular frame 11 relative to the arc sleeve through the positioning sleeve 16. At this time, the support wheel 25 changes the gap between the rotating friction plate 8 and the fixed friction plate 6, thereby changing the diameter of the finished crushed material.

[0024] The utility model has novel structure, ingenious conception and simple and convenient operation. The purpose of adjusting the diameter of crushed particles is effectively achieved through the design, and the function of secondary crushing is added.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
