Description

Technical Field

[0001] This application relates to the technical field of feed production equipment, and in particular to a feed pellet mill. Background Technology

[0002] Granulation is a process that causes finer particles of powder to agglomerate into coarser granules due to the flowability of the powder. Granulation is the operation of processing materials in powder, molten liquid, aqueous solution, etc., into granules with a certain shape and size. The concept of biological feed has only been proposed in the last ten years or so, and its definition and connotation are constantly changing with the development of science and practice.

[0003] In a broad sense, biological feed should include all feeds or raw materials except for artificially synthesized additives. What people commonly refer to as biological feed uses cassava, potatoes, sweet potatoes, fruits, etc., as raw materials. After microbial fermentation, the starch is converted into protein and then made into pellets to replace grains in feed, significantly reducing feed costs.

[0004] There are many existing pelleting methods, but most of them cannot change the size of feed pellets without changing the mold. Therefore, changing the size of the feed pellets requires changing the size of the mold, which leads to a decrease in feed pelleting efficiency due to mold replacement. Summary of the Invention

[0005] In order to change the particle size of feed during the feed production process, this application provides a feed pellet mill.

[0006] The feed pellet mill provided in this application adopts the following technical solution: A feed pellet mill includes a cylinder with a pelleting plate installed inside the cylinder. The pelleting plate has multiple pelleting holes. A clamping mechanism is located above the pelleting plate for pressing feed onto the pelleting plate. A feeding assembly for adding material to the pelleting plate is installed on the cylinder. Multiple annular grooves are formed on the side of the pelleting plate away from the clamping mechanism. Each annular groove corresponds to one of the pelleting holes, and the pelleting holes are located within the annular grooves. A variable-diameter cone is slidably connected within each annular groove. The variable-diameter cone gradually narrows on the side away from the clamping mechanism and is slidably inserted into the annular groove. A driving assembly is installed on the pelleting plate for driving the variable-diameter cone to slide within the annular groove. The variable-diameter cone includes multiple sector plates surrounding its axis. An elastic element connects two adjacent sector plates. The width of the annular groove is greater than the thickness of the sidewall of the variable-diameter cone.

[0007] By adopting the above technical solution, feed can be added into the cylinder through the feeding component, and then the feed can be pressed onto the pelleting plate for pelleting by the pressing component. At the same time, the driving component can drive the variable diameter cone to move in the annular groove, so that the feed passes through the pelleting hole and then enters the variable diameter cone with a variable diameter. By sliding the variable diameter cone in the annular groove, the distance between the various sector plates in the variable diameter cone can be adjusted, thereby changing the area of ​​the opening of the variable diameter cone. Thus, the diameter of the feed pellets can be changed during feed production, and the diameter of the variable diameter cone can be adjusted multiple times or repeatedly during production, thereby improving the efficiency of feed pelleting.

[0008] Optionally, the pressing mechanism includes a hydraulic cylinder mounted on the cylinder, a pressing plate connected to the piston rod of the hydraulic cylinder, the outer wall of the pressing plate abutting against the inner wall of the cylinder, a plurality of feed holes arranged around the axis of the pressing plate on the pressing plate, and the pressing mechanism further includes a sealing component for sealing the feed holes.

[0009] By adopting the above technical solution, the feed can be placed on the upper part of the pelleting plate through the feed inlet, and then the feed inlet can be blocked by the sealing component. Then, the feed can be pressed down by the extrusion plate driven by the hydraulic cylinder, thereby quickly extruding the feed onto the pelleting plate.

[0010] Optionally, the extrusion plate has a placement groove, the sealing assembly includes a connecting block fixed to the extrusion plate, a drive motor is installed in the connecting block, the output shaft of the drive motor is placed in the placement groove, a plurality of sealing plates are slidably connected in the placement groove, the sealing plates correspond one-to-one with the feed holes, and the connecting rod is fixed to the arc-shaped sidewall of the output shaft of the drive motor.

[0011] By adopting the above technical solution, the drive motor can be started, and the drive motor can drive the sealing plate to move simultaneously through multiple connecting rods, thereby quickly sealing the feed hole.

[0012] Optionally, the feeding assembly includes a feeding pipe, a stirring pipe is installed inside the cylinder, an auger is installed inside the stirring pipe, a stirring motor for driving the auger to rotate is installed on the stirring pipe, and a discharge port is opened at the end of the stirring pipe away from the stirring motor, and the discharge port is located inside the cylinder.

[0013] By adopting the above technical solution, the crushed feed can be placed in the mixing tube through the feed pipe, and then the auger can be rotated by the mixing motor, thereby stirring and mixing the feed, and the feed can enter the cylinder through the discharge port.

[0014] Optionally, the feeding assembly further includes an inlet coil fixedly connected to and connected to the outlet, wherein multiple outlet pipes are fixedly connected to the arc-shaped sidewall of the inlet coil, and the outlet pipes correspond one-to-one with the inlet holes.

[0015] By adopting the above technical solution, the feed after mixing can fall directly into the feed hole through the discharge hole on the feed coil, thereby reducing the accumulation of material on the upper part of the extrusion plate.

[0016] Optionally, the lower end of the granulation plate is provided with an installation groove, and the driving assembly includes an electric telescopic rod installed in the installation groove. The telescopic end of the electric telescopic rod is fixedly connected to a driving rod, and the driving rod is fixedly connected to the variable diameter cone.

[0017] By adopting the above technical solution, the drive rod can be moved by the electric telescopic rod, thereby quickly controlling the movement of the variable diameter cone in the annular groove by controlling the extension and retraction of the electric telescopic rod, thus quickly changing the diameter of the variable diameter cone.

[0018] Optionally, a sleeve is provided inside the granulation hole, the sleeve is coaxially arranged with the granulation hole, and a vibration mechanism is provided on the granulation plate for driving the sleeve to vibrate.

[0019] By adopting the above technical solution, the sleeve can be vibrated by the vibration mechanism, thereby reducing the amount of feed adhering to the pelleting hole and thus reducing the amount of feed residue in the pelleting hole.

[0020] Optionally, the vibrating mechanism includes a plurality of first springs, the first springs being arranged around the outer wall of the sleeve, one end of the first spring being fixedly connected to the outer wall of the sleeve, and the other end of the first spring abutting against the inner wall of the granulation hole. The vibrating mechanism also includes an abutting component for abutting against the outer wall of the sleeve.

[0021] By adopting the above technical solution, the sleeve can be abutted by the abutting component, causing the first spring to extend or compress, thereby causing the sleeve to reciprocate and thus achieving the vibration of the sleeve.

[0022] Optionally, the granulation plate has a placement cavity, which corresponds one-to-one with the granulation hole. The abutment assembly includes a slide rod passing through the placement cavity. A limit ring is fixedly connected to the slide rod. A second spring is fixed between the limit ring and the inner wall of the placement cavity. One end of the slide rod passes through the placement cavity and abuts against the outer wall of the sleeve. The other end of the slide rod passes through the placement cavity and is placed in the annular groove. A stepped groove is formed on the inner arc surface of the variable diameter cone. The end of the slide rod abuts against the stepped groove.

[0023] By adopting the above technical solution, when the variable diameter cone moves, the sliding rod can be subjected to force through the stepped groove, causing the sliding rod to move in the placement cavity. Under the action of the second spring, the sliding rod moves back and forth in the placement cavity, thereby causing the sliding rod to repeatedly impact the outer wall of the casing. Thus, the casing can be vibrated without additional force.

[0024] Optionally, the elastic element is configured as an extended rubber plate fixed between the two sector plates, the extended plate being arranged along the length direction of the sector plates.

[0025] By adopting the above technical solution, the connection between two sector plates can be achieved by extending the rubber sheet, thereby allowing the distance between the two sector plates to be flexibly changed.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The distance between the various sector plates in the variable diameter cone can be adjusted, thereby changing the area of ​​the opening of the variable diameter cone. This allows for the alteration of the feed pellet diameter during feed production, and the diameter of the variable diameter cone can be adjusted multiple times or repeatedly during production, thereby improving the efficiency of feed pelleting. 2. After mixing, the feed can fall directly into the feed hole through the discharge hole on the feed coil, thereby reducing the accumulation of material on the upper part of the extrusion plate; 3. When the variable diameter cone moves, the stepped groove can apply force to the slide rod, causing the slide rod to move within the placement cavity. Under the action of the second spring, the slide rod reciprocates within the placement cavity, thereby causing the slide rod to reciprocate and impact the outer wall of the casing. Thus, the casing can be vibrated without additional force. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0030] An embodiment of this application is: a feed pellet mill, referring to... Figure 1 and Figure 2 It includes a cylindrical body 1 arranged in a columnar shape, and a feeding assembly 4 for adding feed into the cylinder 1 is provided at the upper end of the cylinder 1.

[0031] The feeding assembly 4 includes a stirring tube 42 that passes through and is fixed to the upper end of the cylinder 1. A steam input pipe 46 for adding steam into the stirring tube 42 is fixedly connected and communicated with the stirring tube 42. The axis of the stirring tube 42 is perpendicular to the axis of the cylinder 1. Both ends of the stirring tube 42 are located outside the cylinder 1. A feed pipe 41 is fixedly connected and communicated to the arc-shaped sidewall of one end of the stirring tube 42. A stirring motor 47 is fixedly connected to the other end of the stirring tube 42. An auger 43 is installed inside the stirring tube 42 along the length of the stirring tube 42. The output shaft of the stirring motor 47 passes through the sidewall of the stirring tube 42 and is fixedly connected to the auger 43. A discharge port is opened at the end of the stirring tube 42 away from the feed pipe 41.

[0032] The feeding assembly 4 also includes a feeding coil 44, which is connected to the discharge port and is fixedly connected to and connected to the stirring tube 42. The feeding coil 44 is arranged around the axis of the cylinder 1. Multiple discharge pipes 45 are fixedly connected to and connected to the arc-shaped sidewall at the lower end of the feeding coil 44, and the discharge pipes 45 are arranged along the circumference of the feeding coil 44.

[0033] Feed can be added into the mixing tube 42 through the feed pipe 41, and then steam can be added into the mixing tube 42 through the steam input pipe 46 to humidify the material in the mixing tube 42. At the same time, the mixing motor 47 can be started to drive the auger 43 to rotate, so that the material moves towards the feed coil 44 during the mixing process, and falls into the cylinder 1 through the feed coil 44 and the discharge pipe 45.

[0034] Reference Figure 3 , Figure 4 and Figure 5 A pelletizing plate 2 is fixedly connected inside the cylinder 1. The pelletizing plate 2 is parallel to the end face of the cylinder 1. A pressing mechanism 3 is installed on the cylinder 1 to press the feed onto the pelletizing plate 2 for pelleting.

[0035] The pressing mechanism 3 includes a hydraulic cylinder 31 installed on the upper end face of the cylinder 1. The end of the piston rod of the hydraulic cylinder 31 passes through the cylinder 1 and is connected to a pressing plate 32. The pressing plate 32 is slidably connected inside the cylinder 1. The pressing plate 32 has multiple feed holes 321, which correspond one-to-one with the discharge pipe 45. The feed discharged from the discharge pipe 45 can fall directly into the feed holes 321. The pressing mechanism 3 also includes a sealing component 33 for sealing the feed holes 321.

[0036] The sealing assembly 33 includes a connecting block 334, with a connecting groove 3341 at the lower end of the connecting block 334. The connecting block 334 is fixedly connected to the upper end face of the extrusion plate 32. The sealing assembly 33 also includes a drive motor 332 fixed in the connecting groove 3341. The extrusion plate 32 has a placement groove 322, which is connected to the feed hole 321. A sealing plate 331 for sealing the feed hole 321 is provided at the feed hole 321. The sealing plate 331 corresponds one-to-one with the feed hole 321. A connecting rod 333 is fixedly connected to the sealing plate 331. The other end of the connecting rod 333 is fixedly connected to the arc-shaped side wall of the output shaft of the drive motor 332.

[0037] Thus, the drive motor 332 can drive multiple sealing plates 331 to move simultaneously within the groove 322, so that the sealing plates 331 block the feed hole 321. Then, the hydraulic cylinder 31 can be activated to drive the extrusion plate 32 to move towards the granulation plate 2 and finally press it onto the granulation plate 2.

[0038] Reference Figure 5 and Figure 6The granulation plate 2 has multiple granulation holes 21 and multiple annular grooves 22 on the side of the granulation plate 2 away from the extrusion plate 32. The annular grooves 22 correspond one-to-one with the granulation holes 21 and the granulation holes 21 are placed in the annular grooves 22. The annular grooves 22 gradually shrink from top to bottom towards their own axis. A variable diameter cone 5 is slidably connected in the annular grooves 22. The variable diameter cone 5 gradually shrinks on the side away from the pressing mechanism 3, and the width of the annular grooves 22 is greater than the thickness of the side wall of the variable diameter cone 5.

[0039] The variable diameter cone 5 is slidably inserted into the annular groove 22. The variable diameter cone 5 includes a plurality of sector plates 51 surrounding the axis of the variable diameter cone 5. The sector plates 51 are made of elastic material. An elastic element 52 for connecting the two adjacent sector plates 51 is provided. In the figure, the elastic element 52 is set as an extension plate. The extension plate is set along the length direction of the sector plate 51 and together with the sector plate 51 forms a cone shape.

[0040] The pelletizing plate 2 is equipped with a drive assembly 6 for driving the variable diameter cone 5 to slide in the annular groove 22. The lower end of the pelletizing plate 2 is provided with multiple mounting grooves 23, and every two mounting grooves 23 correspond to one pelletizing hole 21. The pelletizing hole 21 is located between two mounting grooves 23.

[0041] The drive assembly 6 includes an electric telescopic rod 61 fixed in the mounting groove 23. The telescopic end of the electric telescopic rod 61 is located below the granulation plate 2, and a drive rod 62 is fixedly connected to the end of the telescopic end of the electric telescopic rod 61. The end of the drive rod 62 away from the electric telescopic rod 61 is fixedly connected to the arc-shaped outer wall of the variable diameter cone 5.

[0042] Therefore, by activating the electric telescopic rod 61, the electric telescopic rod 61 drives the variable diameter cone 5 to slide within the annular groove 22 via the drive rod 62. During the sliding process, the variable diameter cone 5 can deform the extended rubber plate under the restriction of the annular groove 22, thereby changing the distance between its fan-shaped plates 51, thus changing the diameter of the opening at the lower end of the variable diameter cone 5. This restricts the feed falling into the variable diameter cone 5 through the pelleting hole 21 of the self-made pellet plate 2, thereby changing the particle size of the feed.

[0043] A sleeve 8 is provided inside the pelleting hole 21 and is coaxially arranged with the pelleting hole 21. The pelleting plate 2 is provided with multiple sets of vibration mechanisms 9 for vibrating the sleeve 8. The vibration mechanism 9 corresponds to the sleeve 8 one by one. In order to reduce the occurrence of feed placed in the pelleting hole 21 sliding out from between the sleeve 8 and the inner wall of the pelleting hole 21 when the vibration mechanism 9 vibrates the sleeve 8, a blocking ring 7 is fixedly connected to the upper end of the sleeve 8. The blocking ring 7 is coaxially arranged with the sleeve 8.

[0044] The vibrating mechanism 9 includes a plurality of first springs 91 arranged around the axis of the sleeve 8. One end of the first spring 91 is fixedly connected to the arc-shaped outer wall of the sleeve 8, and the other end of the first spring 91 is fixedly connected to the inner wall of the granulation hole 21. The vibrating mechanism 9 also includes an abutting component 92 for touching the sleeve 8 and causing the sleeve 8 to reciprocate under the action of the first springs 91.

[0045] The granulation plate 2 has a placement cavity 24, which corresponds one-to-one with the granulation hole 21. The abutment component 92 includes a slide rod 921 that passes through the placement cavity 24. The axis of the slide rod 921 is perpendicular to the axis of the sleeve 8. A limit ring 922 is fixedly connected to the slide rod 921. The limit ring 922 is placed in the placement cavity 24. A second spring 93 is fixedly connected between the limit ring 922 and the inner wall of the placement cavity 24. One end of the slide rod 921 passes through the side wall of the placement cavity 24 and abuts against the outer wall of the sleeve 8. Under the action of the second spring 93, the other end of the slide rod 921 passes through the side wall of the placement cavity 24 and is placed in the annular groove 22. A stepped groove 53 is formed on the inner arc surface of the variable diameter cone 5. The end of the slide rod 921 placed in the annular groove abuts against the stepped groove 53.

[0046] Therefore, when the variable diameter cone 5 slides in the annular groove 22, the stepped groove 53 on the variable diameter cone 5 will abut against the end of the slide rod 921, which will drive the slide rod 921 to slide back and forth in the placement cavity 24, and impact the sleeve 8 while sliding, thereby causing the sleeve 8 to vibrate, and causing the feed residue on the inner wall of the sleeve 8 to be shaken off from the inner wall of the sleeve 8.

[0047] The implementation principle of this application embodiment is as follows: When in use, the stirring motor 47 is started, and steam is added to the stirring tube 42 through the steam input pipe 46. Then, feed is added to the stirring tube 42 through the feed pipe 41. The feed that has been stirred then enters the pelleting plate 2 through the feed coil 44. Then, the sealing component 33 is started to seal the feed inlet hole 321 on the extrusion plate 32. Then, the hydraulic cylinder 31 is started to press the feed onto the pelleting plate 2 for pelleting. At the same time, the variable diameter cone 5 can be slid in the annular groove 22 by controlling the drive component 6, thereby changing the particle size of the feed. At the same time, the vibrating mechanism 9 vibrates the sleeve 8 to reduce the feed residue in the sleeve 8, thereby completing the feed pelleting process.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
