Description

Technical Field

[0001] The invention relates to the technical field of feed processing, in particular to a powder blending and granulating device for biological feed processing. Background Art

[0002] Feed refers to food used to feed livestock, poultry, aquatic animals and other animals to meet their nutritional needs for growth, development, reproduction and production (such as milk production, egg production, wool production, etc.). There are many types of feed, which can be divided into roughage, concentrated feed, green feed, additive feed, complete feed, biological feed, etc. according to the source of raw materials, nutritional components, processing methods, etc.

[0003] In order to promote the uniform distribution of nutrients in feed, improve the taste of feed, increase the feed intake of animals, reduce the occurrence of animal digestive tract diseases, improve the health of animals, increase the density of feed, facilitate storage and transportation, and reduce the dust loss of feed during transportation and feeding, the powdered or granular raw materials will be processed into granular feed with a certain shape and density through feed processing and granulating equipment.

[0004] The existing feed processing and pelleting equipment may encounter the following problems during use:

[0005] In the process of feed processing and pelleting, when feed raw materials and additives are mixed inside the equipment, in order to mix the feed raw materials evenly, the structure of the stirring device inside the equipment is usually complicated, with dead corners and hard-to-reach areas. It is difficult to clean these places later, and residues are easily accumulated in these parts, resulting in cross-contamination between finished feed products when different batches or different types of feed raw materials and additives are mixed inside the equipment, which not only affects the hygienic quality of the feed, but also may cause risks to animal health;

[0006] At the same time, if the residual feed inside the dead corner is not cleaned thoroughly, the residual feed will easily breed bacteria, mold and other microorganisms. When the next batch of feed raw materials are mixed, these microorganisms and bacteria will multiply in the next batch of feed raw materials, causing feed deterioration and affecting animal health.

[0019] (III) Beneficial effects

[0020] The powder blending and granulating equipment for biological feed processing provided by the present invention has the following beneficial effects:

[0021] 1. By setting the interior of the stirring shaft to be a cavity and the stirring shaft to be a bendable material, when the feed raw materials need to be stirred, the stirring shaft is inflated and straightened to stir the feed raw materials. When stirring is not needed, the stirring shaft becomes soft and droops, and a part of the feed raw materials adhered to the surface of the stirring shaft can flow down from the surface of the stirring shaft, so that the feed raw materials adhered to the surface of the stirring shaft are less. Compared with the existing stirring shaft that needs to clean more adhered feed raw materials, cleaning the stirring shaft with less adhered feed raw materials can complete the cleaning task more quickly and easily, saving time and resources required for cleaning. In addition, the scraper is fitted to the inner wall of the mixing box. When the active shaft drives the scraper to rotate through the auxiliary rod, the scraper can scrape off the feed raw materials adhered to the inner wall of the mixing box, reducing the feed raw materials adhered to the inner wall of the mixing box, thereby making it easier to clean the inside of the equipment, reducing the downtime caused by cleaning, thereby improving the overall production efficiency. Since there are fewer feed raw materials adhered to the inside of the equipment, it can reduce the waste of feed raw materials and improve the utilization rate of feed raw materials.

[0022] 2. Through the connecting ring set inside the stirring shaft, when the stirring shaft becomes soft and droops, the outer surface of the stirring shaft will not fit with the outer surface of the driving shaft, reducing the existence of cleaning dead angles caused by the contact between the stirring shaft and the outer surface of the driving shaft, making the cleaning of the driving shaft and the stirring shaft surface easier, and thus the cleaning work inside the mixing box can be more thorough and efficient, reducing cleaning time and labor costs, preventing cross-contamination between different batches or different types of feed raw materials, ensuring the quality and safety of the feed, avoiding the growth of bacteria, mold and other microorganisms caused by incomplete cleaning, reducing the risk of microbial contamination, improving the sanitary quality of the feed, ensuring the consistency of different batches of feed products, thereby improving product quality. In addition, it can also reduce the scale formed by the accumulation of residues inside the equipment and the corrosion caused to the equipment.

[0023] 3. By setting one side of the extrusion block as an inclined surface, and the extrusion block is located on the movement trajectory of the auxiliary block, when in use, the auxiliary rod drives the auxiliary block connected to the dispersion disk to rotate to the extrusion block, the extrusion block squeezes the dispersion disk downward through the auxiliary block, and the spring 2 connected to the dispersion disk is compressed. At the same time, the spring 2 stores a certain elastic potential energy. When the auxiliary rod continues to drive the auxiliary block connected to the dispersion disk to rotate away from the extrusion block, the elastic potential energy stored in the spring 2 is released, thereby driving the dispersion disk to vibrate to a certain extent. When the dispersion disk vibrates, the feed raw materials transported to the top of the dispersion disk through the feeding pipe can be evenly dispersed into the mixing box through the through holes opened on the surface of the dispersion disk as the dispersion disk vibrates, so that different raw material particles can contact with other raw material particles more quickly, thereby accelerating the mixing process, improving the mixing efficiency, and facilitating the uniform mixing of the feed raw materials, ensuring that all nutrients are uniformly distributed in the entire feed batch, improving the consistency of the feed product, ensuring that the animals obtain balanced nutrition, and helping to improve the health of the animals.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] refer to Figures 1 to 9A powder blending and granulating device for biological feed processing according to a preferred embodiment of the present invention will be described in detail below. A powder blending and granulating device for biological feed processing includes a mixing box 1. The upper surface of the mixing box 1 is connected to a feeding pipe 2. A granulating box 3 is detachably connected to the lower part of the mixing box 1. The mixing box 1 and the granulating box 3 are connected, and the mixing box 1 and the granulating box 3 are located in the same vertical section. A driving shaft 4 is coaxially connected to the inside of the mixing box 1. The driving shaft 4 is fixedly connected to the output shaft end of the motor. The top of the driving shaft 4 passes through the mixing box 1 and extends to the top of the mixing box 1. The inside of the driving shaft 4 is set as a cavity. The outer surface of the driving shaft 4 located inside the mixing box 1 is fixedly connected to a connecting ring 5. When the stirring shaft 6 softens and droops, the stirring The shaft 6 will not fit with the surface of the driving shaft 4, reducing the existence of cleaning dead angles caused by the contact between the stirring shaft 6 and the outer surface of the driving shaft 4, making it easier to clean the surfaces of the driving shaft 4 and the stirring shaft 6, making the cleaning work inside the mixing box 1 more thorough and efficient, reducing cleaning time and labor costs, and preventing cross-contamination between different batches or different types of feed raw materials, ensuring the quality and safety of the feed, avoiding the growth of bacteria, molds and other microorganisms caused by incomplete cleaning, reducing the risk of microbial contamination, improving the sanitary quality of the feed, ensuring the consistency of different batches of feed products, thereby improving product quality. In addition, it can also reduce the scale formed by the accumulation of residues inside the equipment and the corrosion caused to the equipment;

[0037] The end of the connecting ring 5 away from the driving shaft 4 is set as an inclined surface, so that after the stirring shaft 6 is bent vertically, the inner wall of the stirring shaft 6 does not completely fit with the end of the connecting ring 5 away from the driving shaft 4, so that the gas transported through the internal cavity of the driving shaft 4 can more easily enter the interior of the cavity set in the stirring shaft 6 in subsequent use

[0038] The connecting ring 5 is evenly arranged, and the outer surface of the connecting ring 5 is fixedly connected with a stirring shaft 6. The end of the stirring shaft 6 close to the driving shaft 4 is fixedly connected to the driving shaft 4. The interior of the stirring shaft 6 is arranged as a cavity, and the stirring shaft 6 is made of a bendable material, specifically polyurethane material, with good flexibility and wear resistance.

[0039] The outer surface of the driving shaft 4 extending above the mixing box 1 is provided with a ring-shaped slide groove 7. There are two slide grooves 7, which are distributed up and down on the same vertical plane. The outer surface of the driving shaft 4 extending above the mixing box 1 is rotatably connected with a swivel 8. The surface of the swivel 8 on one side close to the center line of the driving shaft 4 is provided with a circular groove 9. The circular grooves 9 are symmetrically distributed with reference to the vertical center line of the driving shaft 4. The inside of the circular grooves 9 are fixedly connected with a spring 10, and the end of the spring 10 close to the driving shaft 4 is fixedly connected with a slider 11, and the slider 11 is slidably connected to the inside of the slide groove 7.

[0040] The outer surface of the swivel 8 is connected with a connecting pipe 12 , and one end of the connecting pipe 12 away from the swivel 8 is fixedly connected with an air pump. The outer surface of the driving shaft 4 is evenly penetrated with circular holes 13 .

[0041] The outer surface of the driving shaft 4 located inside the mixing box 1 is rotatably connected to an auxiliary ring 14, the outer surface of the auxiliary ring 14 is fixedly connected to an auxiliary rod 15, and the end of the auxiliary rod 15 away from the auxiliary ring 14 is fixedly connected to a scraper 16, the auxiliary rod 15 and the scraper 16 are distributed in a circular array with the center point of the driving shaft 4 as a reference, and the side of the scraper 16 away from the driving shaft 4 is in contact with the inner wall of the mixing box 1. When in use, the scraper 16 is in contact with the inner wall of the mixing box 1, and the scraper 16 scrapes off the feed raw materials adhered to the inner wall of the mixing box 1 and stirs it, which can reduce the feed raw materials adhered to the inner wall of the mixing box 1. A small amount of feed raw materials adhered to the inner wall of the mixing box 1 can be more easily and thoroughly cleaned, which can avoid introducing bacteria or other contaminants into the next batch of feed, prevent cross-contamination of different batches of feed, and ensure the safety and quality of the feed.

[0042] The outer surface of the auxiliary ring 14 is fixedly connected with a bevel gear 17, the inner wall of the mixing box 1 is fixedly connected with a fixing rod 18, the end of the fixing rod 18 away from the inner wall of the mixing box 1 is fixedly connected with a bevel gear 2 19, the bevel gear 2 19 is meshed with the bevel gear 17, the outer surface of the driving shaft 4 is fixedly connected with a bevel gear 3 20, the bevel gear 3 20 is meshed with the bevel gear 2 19. When in use, the scraper 16 connected to the bevel gear 17 through the auxiliary ring 14 and the stirring shaft 6 connected to the driving shaft 4 rotate in opposite directions with the driving shaft 4 as the central axis. The reverse rotation of the scraper 16 and the stirring shaft 6 can increase the mixing effect, make different feed raw materials more evenly mixed together, ensure that various nutrients in different feed raw materials are evenly distributed, avoid the situation of excessive or insufficient local nutrients, and at the same time speed up the mixing process, improve the mixing efficiency of feed raw materials, shorten the preparation time, and improve production capacity.

[0043] The upper surface of the auxiliary rod 15 is fixedly connected with a spring 21, and one end of the spring 21 away from the auxiliary rod 15 is fixedly connected with a dispersion disk 22. When in use, the extrusion block 24 presses the dispersion disk 22 downward through the auxiliary block 23, and the spring 21 connected to the dispersion disk 22 is compressed. At the same time, the spring 21 stores a certain elastic potential energy. When the auxiliary rod 15 continues to drive the auxiliary block 23 connected to the dispersion disk 22 to rotate away from the extrusion block 24, the elastic potential energy stored in the spring 21 is released, thereby driving the dispersion disk 22 to vibrate to a certain extent. When the dispersion disk 22 vibrates, the feed raw materials transported to the top of the dispersion disk 22 through the feeding pipe 2 can be evenly dispersed into the mixing box 1 through the through holes opened on the surface of the dispersion disk 22 as the dispersion disk 22 vibrates, so that different raw material particles can contact with other raw material particles more quickly, thereby accelerating the mixing process, improving the mixing efficiency, and facilitating the uniform mixing of the feed raw materials, ensuring that all nutrients are uniformly distributed in the entire feed batch, improving the consistency of the feed product, ensuring that the animals obtain balanced nutrition, and helping to improve the health and growth performance of the animals;

[0044] The upper surface of the dispersion disk 22 is evenly penetrated with through holes, the upper surface of the dispersion disk 22 is fixedly connected with an auxiliary block 23, the top wall of the mixing box 1 is fixedly connected with an extrusion block 24, one side of the extrusion block 24 is set as an inclined surface, the extrusion block 24 is located on the movement trajectory of the auxiliary block 23, and the auxiliary block 23 and the extrusion block 24 are distributed in a circular array with the center point of the driving shaft 4 as a reference.

[0045] The bottom end of the driving shaft 4 extends to the inside of the pelletizing box 3, and the outer surface of the driving shaft 4 extending to the inside of the pelletizing box 3 is fixedly connected with a baffle 25. Two connecting rods 26 are located below the baffle 25 to prevent the feed materials from accumulating on the surface of the diaphragm 27 when the connecting rod 26 rotates to retract the diaphragm 27. The outer surface of the driving shaft 4 is provided with a connecting rod 26. There are two connecting rods 26, and one of the connecting rods 26 is fixedly connected to the driving shaft 4, and the other connecting rod 26 is slidably connected to the outer surface of the driving shaft 4. The connecting rod 26 slidably connected to the driving shaft 4 is connected to the driving device, and the driving device drives the connecting rod 26 to rotate with the center line of the driving shaft 4 as the axis. A diaphragm 27 is fixedly connected between the connecting rods 26, and the diaphragm 27 can be slidably connected to the baffle 25. The baffle 25 scrapes off the feed materials adhered to the surface of the diaphragm 27.

[0046] The outer surface of the driving shaft 4 extending to the inside of the granulation box 3 is fixedly connected with a spiral blade 28, and the side of the spiral blade 28 away from the driving shaft 4 is in contact with the inner wall of the granulation box 3, and the side of the granulation box 3 away from the mixing box 1 is detachably connected to a granulation mold 29, and mold holes are evenly penetrated through the upper surface of the granulation mold 29. A scraper 30 is detachably connected to the inside of the driving shaft 4, and the scraper 30 penetrates the granulation mold 29 and extends to the outside of the granulation box 3, and the scraper 30 is in contact with the bottom of the granulation mold 29.

[0047] The following is the entire working process and working principle of the above embodiment:

[0048] Before use, select suitable feed raw materials, such as grains, soybean meal, fish meal, vitamins, minerals, etc., and carry out necessary crushing and mixing to ensure the uniformity and appropriate particle size of the raw materials. Then, various raw materials are transported to the inside of the mixing box 1 through the conveying mechanism and the feed pipe 2 according to the formula ratio.

[0049] When mixing the feed raw materials, first, the operator presses the swivel 8 downward. When pressing the swivel 8 downward, the slider 11 fixedly connected to the swivel 8 by the spring 10 is squeezed by the portion of the surface of the driving shaft 4 where the slide groove 7 is not provided. At this time, the spring 10 fixedly connected to the slider 11 is compressed. When the swivel 8 is pressed to the slide groove 7 below, the slider 11 is no longer squeezed by the portion of the surface of the driving shaft 4 where the slide groove 7 is not provided. At this time, the rebound force of the spring 10 pushes the slider 11 to slide and connect to the inside of the slide groove 7 below. At this time, the connecting pipe 12 connected to the surface of the swivel 8 and the circular hole 13 provided on the surface of the driving shaft 4 are at the same height, and the operator The personnel turns on the power of the air pump connected to the connecting pipe 12, and the air pump compresses the gas and transports it to the cavity set inside the driving shaft 4 through the connecting pipe 12 and the circular hole 13. The gas transported to the cavity of the driving shaft 4 is transported to the inside of the cavity set in the stirring shaft 6 through the connecting ring 5. Since the stirring shaft 6 is made of a bendable material, specifically polyurethane material, which has good flexibility and wear resistance, the stirring shaft 6 is straightened after the gas is transported to the cavity of the stirring shaft 6. The hardness of the stirring shaft 6 after being inflated and straightened increases, and it can pass through the feed raw materials more effectively, stir them, and make different feed raw materials evenly mixed together.

[0050] Next, the operator starts the motor and drives the driving shaft 4 to rotate through the output shaft of the motor. When the driving shaft 4 rotates, it drives the stirring shaft 6 and the bevel gear 3 20 fixedly connected to the surface to rotate synchronously. When the bevel gear 3 20 rotates, it drives the bevel gear 1 17 meshed with the bevel gear 2 19 and the bevel gear 3 20 to rotate in the opposite direction to the bevel gear 3 20. When the bevel gear 17 rotates, it drives the auxiliary ring 14 fixedly connected to the bevel gear 17 to rotate. When the auxiliary ring 14 rotates, it drives the scraper 16 fixedly connected to the auxiliary ring 14 through the auxiliary rod 15 to rotate. Since the bevel gear 3 20 and the bevel gear 17 rotate in the opposite direction Therefore, the stirring shaft 6 and the scraper 16 rotate in opposite directions inside the mixing box 1 with the center line of the driving shaft 4 as the axis, so that the stirring shaft 6 and the scraper 16 reversely stir the raw materials inside the mixing box 1. The reverse stirring can increase the movement path and mixing times of the raw materials in the mixing box 1, thereby improving the mixing uniformity of the raw materials and ensuring balanced nutrition of the feed. It can also effectively break up the lumps in the raw materials and prevent the raw materials from being accumulated during the stirring process, ensuring the fluidity of the raw materials during the entire stirring process. Since the shear force generated by the reverse stirring is relatively large, the components with large viscosity or specific gravity difference in the raw materials can be better dispersed and mixed;

[0051] Furthermore, since the scraper 16 is in contact with the inner wall of the mixing box 1, when the scraper 16 rotates, the scraper 16 can scrape off the feed raw materials adhered to the inner wall of the mixing box 1, thereby reducing the feed raw materials adhered to the inner wall of the mixing box 1, making it easier to clean the inside of the equipment, reducing the downtime caused by cleaning, and thus improving the overall production efficiency. Since there are fewer feed raw materials adhered to the inside of the equipment, it can reduce the waste of feed raw materials and improve the utilization rate of feed raw materials.

[0052] Finally, when the auxiliary rod 15 rotates, it drives the dispersion disk 22 connected to the auxiliary rod 15 through the spring 21 to rotate. When the dispersion disk 22 rotates, it drives the auxiliary block 23 connected to the dispersion disk 22 to rotate. Since one side of the extrusion block 24 is set as an inclined surface, and the extrusion block 24 is located on the movement trajectory of the auxiliary block 23, therefore, when the dispersion disk 22 drives the auxiliary block 23 to rotate to the extrusion block 24, the inclined surface on one side of the extrusion block 24 squeezes the dispersion disk 22 downward through the auxiliary block 23. At this time, the spring 21 connected to the dispersion disk 22 is compressed, and the spring 21 stores a certain amount of elastic potential energy. The dispersion disk 22 continues to drive the auxiliary block 23 to rotate away from the extrusion block. At 24, the elastic potential energy stored in the spring 21 is released, thereby driving the dispersion plate 22 to generate a certain vibration. When the dispersion plate 22 vibrates, the feed raw materials transported to the top of the dispersion plate 22 through the feeding pipe 2 can be evenly dispersed into the mixing box 1 through the through holes opened on the surface of the dispersion plate 22 as the dispersion plate 22 vibrates, so that different raw material particles can contact with other raw material particles more quickly, thereby accelerating the mixing process, improving the mixing efficiency, and facilitating the uniform mixing of the feed raw materials, ensuring that all nutrients are uniformly distributed in the entire feed batch, improving the consistency of the feed product, ensuring that the animals obtain balanced nutrition, and helping to improve the health of the animals.

[0053] When the mixing of the feed raw materials is completed, the operator pushes the swivel 8 upward. When pushing the swivel 8 upward, the slider 11 fixedly connected to the swivel 8 by a spring 10 is squeezed by the portion of the surface of the driving shaft 4 where the slide groove 7 is not provided. At this time, the spring 10 fixedly connected to the slider 11 is compressed. When the swivel 8 is pushed to the upper slide groove 7, the slider 11 is no longer squeezed by the portion of the driving shaft 4 where the slide groove 7 is not provided. At this time, the rebound force of the spring 10 pushes the slider 11 to slide and connect to the upper slide groove 7. At this time, the connecting pipe 12 connected to the surface of the swivel 8 is no longer at the same height as the circular hole 13 provided on the surface of the driving shaft 4, and the swivel 8 no longer blocks the circular hole 13 provided on the surface of the driving shaft 4. The operator turns off the power of the air pump, and the air pump no longer compresses the gas and passes through the connecting pipe 12 through the circular The gas in the stirring shaft 6 flows out from the circular hole 13 through the cavity of the driving shaft 4. As there is no gas support inside the stirring shaft 6, the stirring shaft 6 becomes soft. As the mixing of the feed materials inside the mixing box 1 is completed and the feed materials are reduced, the softened stirring shaft 6 sags. After the stirring shaft 6 sags, part of the feed materials adhered to the surface can flow down from the surface of the stirring shaft 6, so that the feed materials adhered to the surface of the stirring shaft 6 are less. Compared with the existing stirring shaft 6 with more adhered feed materials, cleaning the stirring shaft 6 with less adhered feed materials can complete the cleaning task more quickly and easily, saving the time and resources required for cleaning.

[0054] Then, the driving device drives the connecting rod 26 slidably connected to the driving shaft 4 to rotate one circle with the center line of the driving shaft 4 as the axis. When the connecting rod 26 rotates, the diaphragm 27 is retracted, so that the feed raw materials mixed inside the mixing box 1 enter the inside of the granulating box 3 through the connecting part between the mixing box 1 and the granulating box 3. When the driving shaft 4 rotates, the spiral blade 28 fixedly connected to the driving shaft 4 is driven to rotate. When the spiral blade 28 rotates, it can push the mixed feed raw materials toward the direction close to the granulating mold 29. When the mixed feed raw materials are pushed to the granulating mold 29 by the spiral blade 28, as the driving shaft 4 drives the spiral blade 28 to rotate, the spiral blade 28 squeezes the mixed feed raw materials through The feed raw materials flow through the die holes opened on the surface of the granulation die 29 to the outside of the granulation box 3. When the driving shaft 4 rotates, it drives the scraper 30 connected to the driving shaft 4 to rotate. Since the scraper 30 is in contact with the bottom of the granulation die 29, the scraper 30 cuts off the feed raw materials that are squeezed by the spiral blade 28 through the die holes opened on the surface of the granulation die 29 to the outside of the granulation box 3 to form pellets. Since the side of the spiral blade 28 away from the driving shaft 4 is in contact with the inner wall of the granulation box 3, when the spiral blade 28 rotates, the side of the spiral blade 28 away from the driving shaft 4 is slidably connected to the inner wall of the granulation box 3, so that less feed raw materials can be attached to the inner wall of the granulation box 3, making it easy to clean the inside of the granulation box 3.
