Description

Technical Field

[0001] This invention relates to the field of raw material crushing technology, specifically to a raw material crushing device for producing amino acids from poultry feathers. Background Technology

[0002] Poultry farming is widespread globally, generating a large amount of poultry feather waste annually. If these feathers are not utilized properly, they not only put pressure on the environment but also waste valuable resources. Poultry feathers are rich in protein and have high potential utilization value. Amino acids are the basic building blocks of protein and have wide applications in many fields such as medicine, food, feed, and cosmetics. By converting poultry feathers into amino acids, efficient resource utilization can be achieved, meeting the amino acid needs of different industries. In the past, poultry feather processing methods were relatively simple and crude. On the one hand, directly discarding or burning feathers caused environmental pollution and resource waste; on the other hand, some simple physical processing methods were insufficient to fully break down the feathers, affecting the efficiency of subsequent amino acid extraction.

[0003] Existing equipment cannot process feathers using a combination of pre-crushing and fine crushing when crushing raw materials. It cannot perform finer grinding and cutting on pre-crushed feathers, resulting in low crushing efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a raw material crushing device for producing amino acids from poultry feathers, comprising:

[0005] A pretreatment cylinder has a feed frame connected to its top, a cover plate rotatably connected to the top of the feed frame via a rotating bolt, a discharge nozzle connected to the bottom of the pretreatment cylinder, a support plate fixedly connected to the outside of the discharge nozzle, and a base fixedly connected to the bottom of the support plate.

[0006] The crushing cylinder has a discharge port located at the center of its bottom.

[0007] Crushing device, used for grading and crushing raw materials;

[0008] A material turning device is used to turn over the raw materials inside the crushing drum;

[0009] The discharge device screens and discharges the crushed raw materials.

[0010] The support plate is provided in two sets, and the two sets of support plates are symmetrically distributed on both sides of the discharge nozzle. The top of the crushing cylinder is connected to the bottom of the discharge nozzle. The outer side of the crushing device is fixedly connected to the top of the base through a bracket. Both ends of the turning device penetrate the crushing cylinder and are rotatably connected to the crushing cylinder through sealed bearings. The discharge device is sleeved on the outer side of the crushing cylinder and fixedly connected to the outer wall of the crushing cylinder.

[0011] The crushing device includes:

[0012] A drive motor, the output end of which is fixedly connected to a rotating column;

[0013] A reinforced blade holder is provided, wherein a first cutting blade is fixedly connected to the outer side of the reinforced blade holder by a combination of bolts and nuts.

[0014] Preferably, multiple sets of reinforced blade holders are provided, and the multiple sets of reinforced blade holders are evenly distributed on the rotating column. The side of the reinforced blade holder away from the first cutting blade is fixedly connected to the outer wall of the rotating column, and the outer side of the drive motor is fixedly connected to the top of the base through a bracket.

[0015] Preferably, the crushing device further includes a rotating rod, one end of which is connected to a rotating column via a belt drive mechanism. A reinforcing block is fixedly connected to the outer side of the rotating rod, and a second cutting blade is fixedly connected to the outer side of the reinforcing block. A drive motor drives the rotating column to rotate, and the rotating column drives the rotating rod to rotate via the belt drive mechanism. The rotating rod then drives the second cutting blade to rotate via the reinforcing block. The rotating second cutting blade pre-cuts the raw material entering the pretreatment cylinder. The raw material after being cut by the second cutting blade is discharged into the crushing cylinder from the discharge nozzle. The rotating column drives the first cutting blade to further finely crush the cut raw material via the reinforcing blade holder. The feathers are processed using a combination of pre-crushing and fine crushing. First, the second cutting blade is used to coarsely process the feathers, breaking them into larger flake or block structures. Then, the first cutting blade is used to finely grind and cut the pre-crushed feathers, effectively improving the crushing efficiency.

[0016] Preferably, both ends of the rotating rod pass through the pretreatment cylinder and are rotatably connected to both ends of the pretreatment cylinder through sealed bearings, and multiple sets of the reinforcing blocks and the second cutting blade are provided.

[0017] Preferably, the turning device includes a turning cylinder, with circular plates fixedly connected to both ends of the turning cylinder. An arc-shaped opening is provided on the outer side of the turning cylinder, and a turning plate is rotatably connected to the inner wall of the arc-shaped opening via a rotating seat. An arc-shaped spring is fixedly connected to one side of the turning plate, and a shovel plate is fixedly connected to the side of the turning plate away from the arc-shaped spring. A rotary motor is fixedly connected to one side of the circular plate, and the rotary motor drives the circular plate to rotate. The circular plate drives the turning cylinder to rotate, and the turning cylinder drives the turning plate to move. The turning plate drives the shovel plate to move along one side of the inner wall of the crushing cylinder. The rotation of the turning cylinder can turn over the feathers inside the crushing cylinder, which can effectively prevent the feathers from accumulating inside the crushing cylinder during crushing and discharge, thereby improving the uniformity of crushing and the efficiency of discharge.

[0018] Preferably, the end of the arc-shaped spring away from the tilting plate is fixedly connected to the outer wall of the tilting cylinder, the circular plate passes through the crushing cylinder and is rotatably connected to the end of the crushing cylinder through a sealed bearing, and the rotating column passes through the circular plate and is rotatably connected to the circular plate through a bearing.

[0019] Preferably, the output end of the rotary motor is fixedly connected to one side of the circular plate, and the outer side of the rotary motor is fixedly connected to the top of the base through a bracket. Multiple sets of arc-shaped openings are provided, and the multiple sets of arc-shaped openings are staggered.

[0020] Preferably, the discharge device includes an arc-shaped screen plate with screen holes on its side. A movable block is fixedly connected to the outer side of the arc-shaped screen plate, and an annular electric slide rail is slidably connected to one side of the movable block via an electric slider. The processed feather crushed product in the crushing cylinder needs to fall from the discharge port into the screen holes and pass through the screen holes for discharge. Feathers that do not pass through the screen holes will fall again from the top of the inner wall of the crushing cylinder under the rotation of the tilting cylinder and be crushed again by the first cutting blade. The crushing continues in the crushing cylinder until it passes through the screen holes, which avoids the problem of unstable product quality caused by incomplete crushing at one time and reduces the waste of raw materials.

[0021] Preferably, the screen holes are provided in three sets, with the apertures of the three sets increasing sequentially. The annular electric slide rail, through its internal electric slider, drives the moving block to move, which in turn drives the arc-shaped screen plate to rotate. The arc-shaped screen plate has screen holes of different apertures, allowing the appropriate size of the screen hole to be rotated to the discharge port according to the different particle size requirements of the raw materials in the amino acid production process. This ensures the consistency of the final feather crushing product's particle size and also allows for adjustment of the discharged crushed material size, improving the adaptability of the device. Two sets of annular electric slide rails are provided, symmetrically distributed on both sides of the arc-shaped screen plate. The annular electric slide rails are fitted onto the outside of the crushing cylinder and fixedly connected to the outer wall of the crushing cylinder.

[0022] This invention provides a raw material crushing device for producing amino acids from poultry feathers. It has the following beneficial effects:

[0023] 1. This raw material crushing equipment for producing amino acids from poultry feathers, through the installation of the crushing device, drives a motor to rotate a rotating column, which in turn drives a rotating rod to rotate via a belt drive mechanism. The rotating rod, in turn, drives a second cutting blade to rotate via a reinforcing block. The rotating second cutting blade pre-cuts the raw material entering the pretreatment cylinder. The raw material after being cut by the second cutting blade is discharged into the crushing cylinder from the discharge nozzle. The rotating column, through the reinforcing blade holder, drives the first cutting blade to further finely crush the cut raw material. By combining pre-crushing and fine crushing, the feathers are processed. First, the second cutting blade is used to coarsely process the feathers, breaking them into larger flakes or blocks. Then, the first cutting blade is used to finely grind and cut the pre-crushed feathers, effectively improving the crushing efficiency.

This raw material crushing equipment for producing amino acids from poultry feathers, through the installation of a turning device, a rotary motor drives a circular plate to rotate, the circular plate drives a turning drum to rotate, and the turning drum drives a turning plate to move while rotating. The turning plate drives a shovel to move along one side of the inner wall of the crushing drum. The rotation of the turning drum can turn over the feathers inside the crushing drum, which can effectively prevent feathers from accumulating inside the crushing drum during crushing and discharge, thereby improving the uniformity of crushing and the efficiency of discharge.

[0025] 3. This raw material crushing equipment for producing amino acids from poultry feathers, through the installation of the discharge device, requires the processed feather crushed products in the crushing cylinder to fall from the discharge port to the screen holes and be discharged through the screen holes. Feathers that do not pass through the screen holes will fall again from the top of the inner wall of the crushing cylinder under the rotation of the rotating cylinder and be crushed again by the first cutting blade. The crushing continues in the crushing cylinder until they pass through the screen holes, avoiding the problem of unstable product quality caused by incomplete crushing at one time, and reducing the waste of raw materials.

This raw material crushing equipment for producing amino acids from poultry feathers, through the setting of screen holes, opens the annular electric slide rail and drives the moving block to move through the electric slider inside, and the moving block drives the arc-shaped screen plate to rotate. The arc-shaped screen plate is provided with screen holes of different diameters. According to the different particle size requirements of the amino acid production process, the screen hole of the appropriate size can be rotated to the discharge port, which can not only ensure the consistency of the particle size of the final feather crushed product, but also adjust the size of the discharged crushed material, thus improving the adaptability of the device.

The side of the reinforced blade holder 83 away from the first cutting blade 84 is fixedly connected to the outer wall of the rotating column 82. The outer side of the drive motor 81 is fixedly connected to the top of the base 11 through a bracket.

[0050] The crushing device 8 also includes a rotating rod 85, one end of which is connected to the rotating column 82 via a belt drive mechanism 86. A reinforcing block 87 is fixedly connected to the outside of the rotating rod 85, and a second cutting blade 88 is fixedly connected to the outside of the reinforcing block 87.

[0051] Both ends of the rotating rod 85 pass through the pretreatment cylinder 1 and are rotatably connected to both ends of the pretreatment cylinder 1 through sealed bearings. Multiple sets of reinforcing blocks 87 and second cutting blades 88 are provided.

[0052] The material turning device 9 includes a turning cylinder 91, with circular plates 92 fixedly connected to both ends of the turning cylinder 91.

[0055] In operation, the worker pours the raw material to be processed from the feed frame 2 into the pretreatment cylinder 1, then flips the cover plate 3 to cover the top of the feed frame 2, preventing the raw material from escaping from the top of the feed frame 2 during crushing. Then, the drive motor 81 is turned on, which drives the rotating column 82 to rotate. The rotating column 82 drives the rotating rod 85 to rotate through the belt transmission mechanism 86. The rotating rod 85 then drives the second cutting blade 88 to rotate through the reinforcing block 87. The rotating second cutting blade 88 pre-cuts the raw material entering the pretreatment cylinder 1. The raw material after being cut by the second cutting blade 88 is discharged from the discharge nozzle 4 into the crushing cylinder 6. The rotating column 82 drives the first cutting blade 84 to further finely crush the cut raw material through the reinforcing blade holder 83. The feathers are processed by combining pre-crushing and fine crushing. First, the second cutting blade 88 is used to coarsely process the feathers, breaking them into larger flakes or blocks. Then, the first cutting blade 84 is used to finely grind and cut the pre-crushed feathers, effectively improving the crushing efficiency.

[0056] Turn on the rotary motor 97, which drives the circular plate 92 to rotate. The circular plate 92 drives the tilting cylinder 91 to rotate. When the tilting cylinder 91 rotates, it drives the tilting plate 94 to move. The tilting plate 94 drives the shovel 96 to move along one side of the inner wall of the crushing cylinder 6. The rotation of the tilting cylinder 91 can turn over the feathers inside the crushing cylinder 6. During crushing and discharge, the feathers can be effectively prevented from accumulating inside the crushing cylinder 6, thereby improving the uniformity of crushing and the efficiency of discharge.

[0057] Second embodiment, please refer to Figures 1-10The present invention provides a technical solution: Based on the first embodiment, the discharge device 10 includes an arc-shaped screen plate 101, the side of the arc-shaped screen plate 101 is provided with screen holes 102, a moving block 103 is fixedly connected to the outer side of the arc-shaped screen plate 101, and a ring electric slide rail 104 is slidably connected to one side of the moving block 103 through an electric slider.

[0058] The screen holes 102 are provided in three sets, and the diameter of the three sets of screen holes 102 increases sequentially. There are two sets of annular electric slide rails 104. The two sets of annular electric slide rails 104 are symmetrically distributed on both sides of the arc-shaped screen plate 101. The annular electric slide rails 104 are sleeved on the outside of the crushing cylinder 6 and fixedly connected to the outer wall of the crushing cylinder 6.

[0059] During use, the processed feathers inside the crushing cylinder 6 need to fall from the discharge port 7 to the screen hole 102 and be discharged through the screen hole 102. Feathers that do not pass through the screen hole 102 will fall again from the top of the inner wall of the crushing cylinder 6 under the rotation of the tilting cylinder 91 and be crushed again at the first cutting blade 84. The crushing continues inside the crushing cylinder 6 until it passes through the screen hole 102, which avoids the problem of unstable product quality caused by incomplete crushing at one time and reduces the waste of raw materials.

[0060] The circular electric slide rail 104 is activated, which drives the moving block 103 to move via the electric slider inside. The moving block 103 drives the arc-shaped screen plate 101 to rotate. The arc-shaped screen plate 101 is provided with screen holes 102 of different aperture sizes. According to the different requirements of the amino acid production process for the particle size of the raw materials, the screen hole 102 of the appropriate size can be rotated to the discharge port 7. This can not only ensure the consistency of the particle size of the final feather crushed product, but also adjust the size of the discharged crushed material, thus improving the adaptability of the device.

[0061] Working principle: The worker pours the raw material to be processed into the pretreatment cylinder 1 from the feed frame 2, then flips the cover plate 3 to cover the top of the feed frame 2, preventing the raw material from overflowing from the top of the feed frame 2 during crushing. Then, the drive motor 81 is turned on, driving the rotating column 82 to rotate. The rotating column 82 drives the rotating rod 85 to rotate via the belt drive mechanism 86. The rotating rod 85 then drives the second cutting blade 88 to rotate via the reinforcing block 87. The rotating second cutting blade 88 pre-cuts the raw material entering the pretreatment cylinder 1. After being cut by the 88-cutting process, the raw material is discharged from the discharge nozzle 4 into the crushing cylinder 6. The rotating column 82 drives the first cutting blade 84 through the reinforced blade holder 83 to further finely crush the cut raw material. The feathers are processed using a combination of pre-crushing and fine crushing. First, the second cutting blade 88 is used to coarsely process the feathers, breaking them into larger flakes or blocks. Then, the first cutting blade 84 is used to perform finer grinding and cutting on the pre-crushed feathers. The rotating motor 97 is turned on, and the rotating motor 97 drives the circular plate 92 to rotate. The circular plate 92 drives the tilting cylinder 91 to rotate. As the tilting cylinder 91 rotates, it drives the tilting plate 94 to move. The tilting plate 94 then drives the shovel plate 96 to move along one side of the inner wall of the crushing cylinder 6. The rotation of the tilting cylinder 91 agitates the feathers inside the crushing cylinder 6, effectively preventing feather accumulation during crushing and discharge. The processed feathers inside the crushing cylinder 6 fall from the discharge port 7 into the screen hole 102 and pass through it for discharge. Feathers that do not pass through the screen hole 102 are then discharged again from the inner wall of the crushing cylinder 6 under the rotation of the tilting cylinder 91. The material falls from the top and is crushed again at the first cutting blade 84, and continues to be crushed in the crushing cylinder 6 until it passes through the screen hole 102. The annular electric slide rail 104 is activated, and the moving block 103 is moved by the electric slider inside. The moving block 103 drives the arc screen plate 101 to rotate. The arc screen plate 101 is provided with screen holes 102 of different diameters. According to the different requirements of the amino acid production process for the particle size of the raw materials, the screen hole 102 of the appropriate size can be rotated to the discharge port 7, which can ensure the consistency of the particle size of the final feather crushed product.

[0062] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
