[0026] As Figures 1 to 10 shown, the present invention discloses a granulator for producing feed detoxifying enzyme, which includes a feeder 1, an extrusion melting device 2 and a granulation cylinder 3. Regarding the feeder 1 and the extrusion melting device 2, they are both prior art devices well-known to those skilled in the art. During actual use, the feeder 1 is connected to the input end of the extrusion melting device 2, and the unmelted enzyme preparation raw material is added into the extrusion melting device 2 through the feeder 1. Then, during the movement of the enzyme preparation raw material in the extrusion melting device 2, the enzyme preparation raw material is gradually made into a liquid state, and subsequently, the granulation operation of the enzyme preparation raw material is continued. An extrusion cylinder 4 is rotatably arranged in the granulation cylinder 3, and a driving device 5 for driving the extrusion cylinder 4 to rotate is arranged on one side of the granulation cylinder 3. The driving device 5 is a prior art device in the prior art for driving the extrusion cylinder 4 to rotate in the granulation cylinder 3, and is composed of a driving motor device and transmission devices such as a belt speed reducer, and is used to drive the extrusion cylinder 4 to rotate in the granulation cylinder 3, which is a technical device well-known to those skilled in the art.

[0027] As Figures 1 to 8As shown in the figure, it further includes a fixed sealing plate 6. One side of the extrusion cylinder body 4 is rotatably connected with the fixed sealing plate 6. The extrusion cylinder body 4 is circumferentially provided with a hole extrusion structure 100. The hole extrusion structure 100 includes a through strip 10. A plurality of through strips 10 are fixedly connected through the side wall of the extrusion cylinder body 4 in a circumferential manner. A plurality of extrusion holes 11 are formed on the through strip 10. After pouring the melted enzyme preparation raw material into the extrusion cylinder body 4, during the rotation of the extrusion cylinder body 4, the liquid enzyme preparation raw material is driven to flow on the inner wall of the extrusion cylinder body 4. The liquid enzyme preparation raw material is extruded into the extrusion holes 11 by the extrusion wheel 7, so that the liquid enzyme preparation is discharged from the extrusion cylinder body 4 in a rod shape; Two extrusion wheels 7 are rotatably arranged inside the extrusion cylinder body 4. An installation cylinder body 12 is arranged inside the extrusion cylinder body 4. The installation cylinder body 12 is fixedly connected to the fixed sealing plate 6. The two extrusion wheels 7 are respectively rotatably arranged on both sides of the installation cylinder body 12. After pouring the liquid enzyme preparation raw material into the extrusion range of the extrusion wheel 7, the extrusion wheel 7 is used to extrude the liquid enzyme preparation from the extrusion cylinder body 4 into the extrusion holes 11; Two driving wheels 13 are rotatably connected inside the installation cylinder body 12. A combined driving structure is arranged between the two driving wheels 13. The extrusion wheel 7 is provided with an extrusion section 14 and a driving section 15. A plurality of extrusion protrusions are circumferentially arranged on the extrusion section 14. The driving wheel 13 cooperates with the driving section 15. The driving section 15 is located between the corresponding two extrusion holes 11. The combined driving structure includes a rotating shaft. The driving wheel 13 is rotatably connected inside the installation cylinder body 12 through the rotating shaft. And transmission gears one 26 are arranged on both rotating shafts. A transmission toothed belt one 27 is transmissionally arranged between the two transmission gears one 26. A first driving motor 28 is arranged outside the granulation cylinder body 3. The output end of the first driving motor 28 is fixedly connected to one of the rotating shafts. When it is necessary to drive the two extrusion wheels 7 to rotate, the first driving motor 28 is started to drive the rotating shaft to rotate. Through the transmission cooperation relationship between the transmission gear one 26 and the transmission toothed belt one 27, the two rotating shafts are driven to rotate, so that the driving wheel 13 abuts against the driving section 15 of the extrusion wheel 7, driving the extrusion wheel 7 to rotate. And the driving section 15 occupies a relatively small area of the whole extrusion wheel 7. Therefore, not too much enzyme preparation raw material will come into excessive contact with the driving section 15. Instead, the enzyme preparation raw material is pushed towards the extrusion holes 11 by the plurality of extrusion protrusions on the extrusion section 14. The distance between the plurality of extrusion protrusions on the extrusion section 14 is the same as the distance between the extrusion holes 11 on the two adjacent through strips 10.

[0028] As Figures 1 to 2 、 Figure 4 、 Figures 6 to 7As shown, a two-way discharging structure 200 is provided between the extrusion cylinder body 4 and the extrusion melting device 2. The extrusion wheel 7 extrudes the raw materials through the hole extrusion structure 100. The two-way discharging structure 200 includes a discharging device 16. The discharging end of the extrusion melting device 2 is communicated with the discharging device 16. Two discharging pipes 17 are communicated with the discharging device 16. The discharging sections of the two discharging pipes 17 are respectively arranged in the extrusion areas of the two extrusion wheels 7. The discharging device 16 is a prior art device for transporting high-temperature liquid materials, which is well-known to those skilled in the art. The high-temperature liquid enzyme preparation raw materials processed by the extrusion melting device 2 are injected into the discharging device 16, and then the high-temperature liquid materials are respectively filled into the two discharging pipes 17 through the discharging device 16, and finally the high-temperature liquid materials are filled into the working areas of the two extrusion wheels 7 in the extrusion cylinder body 4; It should be further noted that after the direct filling of the liquid enzyme preparation material, a large amount of liquid material will accumulate in the discharging area of the discharging pipe 17. At this time, when the extrusion section 14 simply squeezes the liquid material in the direction of the extrusion hole 11, it will be extruded into the extrusion hole 11 due to the continuous filling of the liquid material. When the extrusion cylinder drives the liquid material to move in the extrusion direction of the extrusion wheel 7, the liquid material can be extruded into the extrusion hole 11 through the extrusion section. Therefore, during the working process of the extrusion wheel 7, a plurality of extrusion holes 11 within the range of the extrusion wheel 7 will discharge the liquid material, so that the liquid material is discharged from the extrusion hole 11 in a rod shape.

[0029] As Figures 1 to 8 shown, arc-shaped mounting groove frames 8 are arranged on both outer walls of the extrusion cylinder body 4. Scraper plates 9 are fixedly connected at equal intervals on the inner arc surfaces of the arc-shaped mounting groove frames 8. The scraper plates 9 scrape the raw materials discharged through the hole extrusion structure 100. A plurality of semi-circular scraping grooves 18 are opened on both the upper and lower sides of the scraper plates 9. A slope-shaped groove 19 is opened at the top of the scraper plates 9. A discharge through groove 20 is opened at the bottom of the slope-shaped groove 19. When the scraper plates 9 contact the rod-shaped raw materials exposed from the extrusion cylinder body 4, the semi-circular scraping grooves 18 contact the rod-shaped raw materials. As the extrusion cylinder body 4 continues to rotate, the scraper plates 9 can crush the rod-shaped raw materials. During the extrusion process of the rod-shaped materials from the extrusion cylinder body 4, certain softening problems will occur. The semi-circular scraping grooves 18 can be in full contact with the rod-shaped materials. By using the temperature difference between the scraper plates 9 and the rod-shaped materials, the rod-shaped materials can be quickly hardened. When the arc-shaped mounting groove frames 8 drive the scraper plates 9 to swing quickly and the top ends of the scraper plates 9 crush the rod-shaped materials, the crushed enzyme preparation particles will roll on the slope-shaped groove 19 and finally fall from the scraper plates 9 through the discharge through groove 20 and fall to the bottom of the arc-shaped mounting groove frames 8; The arc-shaped mounting slot frame 8 and a plurality of shovel plates 9 are all swung along the extrusion cylinder 4, and the raw materials within the moving range of the arc-shaped mounting slot frame 8 are shoveled into particles. A pitch-adjusting slot frame 21 is arranged on the outer side of the granulating cylinder 3, and two pitch-adjusting chambers are arranged on the pitch-adjusting slot frame 21. A connecting plate body 22 is slidably connected in the pitch-adjusting chamber, and the connecting plate body 22 is fixedly connected to the arc-shaped mounting slot frame 8. A pitch-adjusting screw 29 is rotatably connected in the pitch-adjusting chamber, and the connecting plate body 22 is transmission-arranged on the pitch-adjusting screw 29. Second drive motors 30 are arranged on both sides of the pitch-adjusting slot frame 21, and the output end of the second drive motor 30 is fixedly connected to the pitch-adjusting screw 29. Because the body of the feed prepared for different animals The volume of livestock and poultry feed is not the same, and the volume of poultry feed is very different. Therefore, when preparing detoxifying enzyme particles, detoxifying enzyme particles of different volumes need to be prepared. During the use of the present invention, the second drive motors 30 on both sides are started to drive the pitch-adjusting screw 29 to rotate, so that the pitch-adjusting screw 29 adjusts the position of the corresponding connecting plate 22 on one side, thereby completing the distance between the arc-shaped mounting slot frame 8 and the shovel plate 9 and the extrusion cylinder 4, so that the rod-shaped raw material contacts the shovel plate 9 after being extruded to a sufficient length. The present invention arranges a plurality of shovel plates 9 in sequence along the rotation path of the extrusion cylinder 4, and can shovel and crush the rod-shaped raw material that has just been extruded according to the corresponding gear; A swing driving structure 300 is provided on one side of the pitch-adjusting slot frame 21. The swing driving structure 300 includes a driving box body, in which a driving shaft 31 is rotatably connected. The driving shaft 31 is fixedly connected to the middle part of the pitch-adjusting slot frame 21. A driving gear 32 is provided on the driving shaft 31. Two driving gears 34 are rotatably connected to the driving box body through a rotating shaft 33. The two driving gears 34 are meshed with each other. A plurality of meshing rods 35 are provided along an arc on the same side of the two driving gears 34. The driving gear 32 is meshed with a plurality of meshing rods 35 located on both sides in turn. When it is necessary to make the pitch-adjusting slot frame 21 drive the two arc-shaped mounting slot frames 8 to swing in a small range, one of the rotating shafts 33 can be continuously driven to rotate. The two driving gears 34 are meshed with each other and drive the two driving gears 34 to move. The drive gear 34 rotates in the opposite direction, and during the rotation of the driving gear 34, the multiple meshing rods 35 areas on the two driving gears 34 mesh with the driving gear 32 in turn, so that the driving gear 32 swings back and forth, driving the driving shaft 31 and the mounting slot frame to swing, so that the arc-shaped mounting slot frame 8 swings on the outside of the extrusion cylinder 4, and an arc-shaped slide rail 41 is fixedly connected to the driving box body, and a rotating ball sliding seat 42 is slidably connected in the arc-shaped slide rail 41. The rotating ball sliding seat 42 is fixedly connected to the driving shaft 31, and an engaging seat 43 for engaging the rotating ball sliding seat 42 is provided in the middle of the arc-shaped slide rail 41. After stopping the swing of the arc-shaped mounting slot frame 8 and leveling the pitch-adjusting slot frame 21, the rotating ball sliding seat 42 and the engaging seat 43 are kept in meshing, thereby improving the stability of the pitch-adjusting slot frame 21; In the present invention, by driving the arc-shaped mounting groove frame 8 and the material shoveling plate 9 to swing, the contact time between the material shoveling plate 9 and the rod-shaped raw material is controlled, so as to control the extrusion speed of the rod-shaped raw material and the contact time period between the rod-shaped raw material and the material shoveling plate 9, and complete the control of the granulation volume of the enzyme preparation.

[0030] Both sides of the bottom of the granulation cylinder body 3 are communicated with discharge hoppers 23. A flexible material conveying channel 24 is communicated between the bottom of the discharge hopper 23 and the bottom of the arc-shaped mounting groove frame 8. An inlet groove 25 is formed on one side of the discharge hopper 23 close to the arc-shaped mounting groove frame 8. The rod-shaped raw materials shoveled by the material shoveling plate 9 will be centrally collected in the arc-shaped mounting groove frame 8, and the rod-shaped raw materials are conveyed into the discharge hopper 23 through the flexible material conveying channel 24. In addition, some enzyme preparation particles will roll down along the side wall of the granulation cylinder body 3, and can also be rolled into the discharge hopper 23 through the inlet groove 25; Such as Figures 1 to 2 and Figures 9 to 10 As shown, a spiral material conveying structure is communicated with the bottom of the discharge hopper 23. A synchronous driving structure 400 is arranged between the two spiral material conveying structures. The spiral material conveying structure includes a material conveying cylinder body 36. The material conveying cylinder body 36 is communicated with the bottom of the discharge hopper 23. One side of the bottom of the material conveying cylinder body 36 is communicated with a discharge port. A spiral conveying rod 37 is rotatably connected in the material conveying cylinder body 36. After the granular material enters the discharge hopper 23, it will enter the material conveying cylinder body 36, drive the spiral conveying rod 37 to rotate, and the spiral conveying rod 37 drives the granular material to be conveyed towards the discharge port; The synchronous driving structure 400 is in transmission cooperation with the swing driving structure 300. The synchronous driving structure 400 includes a gear box. Connecting shafts are fixedly connected to both of the two spiral conveying rods 37. The connecting shafts penetrate and are rotatably connected to the material conveying cylinder body 36. Both of the two connecting shafts are in transmission cooperation with the gear box. A third driving motor 38 is arranged on one side of the gear box. The output end of the third driving motor 38 is in transmission cooperation with the gear box. Transmission gears two 39 are arranged on the output end of the third driving motor 38 and one of the rotating shafts 33. A transmission belt two 40 is arranged in transmission between the two transmission gears two 39. When it is necessary to drive the driving gear 34 and the two spiral conveying rods 37 to rotate, start the third driving motor 38 to drive the two connecting shafts to rotate through the gear box, and complete the driving operation of the spiral conveying rod 37. During the start-up process of the third driving motor 38, the rotating shaft 33 is driven to rotate through the transmission relationship between the transmission gears two 39 and the transmission belt two 40, so that one of the driving gears 34 rotates.

[0031] The working principle of the granulator for producing feed detoxifying enzyme: The enzyme preparation raw material is conveyed into the extrusion melting device 2 through the feeder 1, and then the melted enzyme preparation raw material is filled into the two extrusion wheel 7 areas in the extrusion cylinder 4 through the two-way discharging structure 200. During the rotation of the extrusion cylinder 4, the enzyme preparation raw material is gradually moved into the extrusion wheel 7 area. Under the action of the extrusion wheel 7, the enzyme preparation raw material is discharged through the multiple hole extrusion structure 100, so that the enzyme preparation raw material is extruded from the extrusion cylinder 4 in a rod shape. Each shoveling plate 9 is responsible for the corresponding shoveling area. During the process of the enzyme preparation raw material moving out of the extrusion cylinder 4, the rod-shaped raw material still moves together with the extrusion cylinder 4. Then, the rod-shaped raw material contacts the shoveling plate 9, and the rod-shaped raw material is shoveled into granular form. The distance between the arc-shaped mounting groove frame 8 and the extrusion cylinder 4 can be adjusted, and the arc-shaped mounting groove frame 8 can be driven to reciprocate outside the extrusion cylinder 4 to control the distance between the shoveling plate 9 and the extrusion cylinder 4, so as to realize the shoveling and crushing of the rod-shaped raw material with the corresponding length.
