Description

Technical Field

[0001] This application relates to the field of feed production and processing technology, and in particular to a livestock feed processing equipment and its processing technology. Background Technology

[0002] In the production and processing of livestock feed, ensuring precise proportions of raw materials is crucial for improving feed quality and production efficiency. To achieve this, various raw materials stored in the raw material silo must be transported to a mixer in specific ratios to form a homogeneous feed mixture. Pneumatic conveying systems are widely used in this stage, transporting powdered or granular raw materials from the warehouse to the processing equipment via airflow. However, during pneumatic conveying, powdered raw materials may clump due to high humidity in the external environment, resulting in poor flowability and consequently affecting the accuracy of batching and production efficiency.

[0003] In existing technologies, pneumatic conveying equipment uses filters to intercept and filter raw materials, supplemented by pipeline heating equipment. This allows raw materials that have become clumped due to moisture to dry and disperse, while also maintaining the fluidity of the moist raw materials and preventing them from adhering to the inner wall of the pipeline, thus improving conveying efficiency and batching accuracy. However, when clumped powdery raw materials remain at the filter screen for a long time, it not only affects the conveying speed and batching accuracy, but may also cause the raw materials trapped at the filter screen to be heated for a long time, making them prone to chemical or biological changes. This can affect the quality of the feed, potentially leading to the loss of nutrients in the feed and negatively impacting animal health, thereby reducing the overall quality of feed production. Summary of the Invention

[0004] This application proposes a livestock feed processing equipment and its processing technology, which utilizes gas to impact and break up agglomerated raw materials, and uses a guide plate to vibrate the filter screen, thereby accelerating the filtration and breaking up of agglomerated raw materials and reducing the probability of deterioration caused by prolonged heat exposure of agglomerated raw materials. This improves the overall quality and efficiency of feed production and solves the problem of reduced formulation efficiency and overall feed quality caused by prolonged retention of agglomerated raw materials when using pneumatic conveying equipment to transport powdered raw materials.

[0005] To achieve the above objectives, this application adopts the following technical solution: a livestock feed processing equipment, including a pneumatic conveying pump body, a conveying pipe fixedly installed at the bottom end of the pneumatic conveying pump body, and a filter screen slidably installed on the inner wall of the conveying pipe. A flow guiding mechanism is symmetrically fixedly installed on the inner wall of the conveying pipe, and the flow guiding mechanism is located on the side of the filter screen close to the pneumatic conveying pump body. A high-pressure air pump is connected to the flow guiding mechanism. Two sliders are symmetrically fixedly installed on the outer side of the filter screen. A sliding groove is opened on the inner side wall of the conveying pipe to limit and slide the sliders. An elastic element is fixedly installed on the side of the slider away from the flow guiding mechanism. After the agglomerated raw material is intercepted by the filter screen, as the filter screen and slider slide, the high-pressure air pump is triggered and air is sprayed onto the agglomerated raw material intercepted by the filter screen through the flow guiding mechanism to accelerate the breaking efficiency of the agglomerated raw material.

[0006] Furthermore, the flow guiding mechanism is used to facilitate the real-time breaking up of raw materials agglomerated on the filter screen. The flow guiding mechanism includes a support pipe fixedly installed on the inner wall of the conveying pipe. The side of the support pipe closest to the filter screen is fixedly connected to a main air outlet pipe, and the main air outlet pipe is inclined. The end of the support pipe away from the main air outlet pipe is fixedly connected to an air inlet pipe. The ends of multiple air inlets away from the support pipe are all fixedly connected to a high-pressure air pump through connecting pipes.

[0007] Furthermore, the flow guiding mechanism is used to facilitate the timed breaking up of the agglomerated raw materials on the filter screen. The flow guiding mechanism includes an exhaust pipe fixedly installed on the inner wall of the conveying pipe. The top end of the exhaust pipe is fixedly connected to the bottom end of the inlet pipe. A pressure sensor is fixedly installed on the inner wall of the end of the slide away from the exhaust pipe. The pressure sensor is electrically connected to the controller.

[0008] Furthermore, an adjusting ring is slidably installed on the inner wall of the support tube, and an arc-shaped baffle is fixedly installed on the top of the adjusting ring. A spring is fixedly installed between the bottom wall of the adjusting ring and the inner bottom wall of the support tube to support the adjusting ring.

[0009] Furthermore, a traction rope is fixedly installed at the bottom of the adjusting ring, and the end of the traction rope away from the adjusting ring moves through the bottom wall of the support tube and is fixedly connected to the filter screen.

[0010] Furthermore, a plurality of connecting rods arranged in a ring array are fixedly installed on the side of the filter screen away from the support tube. A connecting shaft is provided on the side of the connecting rod away from the inner wall of the conveying tube. A guide plate is fixedly installed on the end of the connecting shaft away from the connecting rod. One side of the guide plate is a smooth surface and the other side is an arc-shaped surface, which is used to generate a pressure difference when the gas passes through.

[0011] Furthermore, the top end of the connecting shaft movably passes through the bottom wall of the connecting rod and is fixedly installed with a connecting plate. The connecting rod has an internal movable groove that matches the connecting plate, providing space for the connecting plate to move.

[0012] A processing technology for livestock feed includes the following processing steps:

[0013] S1. When the raw materials in the storage bin are transported by the pneumatic conveying pump body, the raw materials that are damp and clumped together will be intercepted and broken up by the filter screen.

[0014] S2. When the filter screen is blocked by agglomerated raw materials, the force-bearing area increases. The filter screen slides under force and drives the adjusting ring and baffle to slide through the traction rope to release the blockage of the adjusting ring on the support pipe, allowing gas to enter the interior of the conveying pipe through the support pipe and spray it onto the agglomerated raw materials through the main outlet pipe to impact and break them up.

[0015] S3. At the same time, when the gas flows through the guide plate, the pressure difference between the smooth surface and the arc-shaped surface of the guide plate causes the filter screen to be subjected to torsional forces in different directions in the cross-sectional direction, which causes the filter screen to vibrate to help break up the agglomerated raw materials on the filter screen.

[0016] The beneficial effects of this invention are as follows:

[0017] This application provides a livestock feed processing equipment and its processing technology. When the pneumatic conveying pump body transports raw materials in the storage bin, it not only achieves multi-stage filtration and disintegration of agglomerated raw materials through multiple filter screens with different aperture sizes, avoiding the raw materials from deteriorating due to prolonged contact with the filter screens, but also uses high-pressure gas to impact and disintegrate the agglomerated raw materials through the support pipe and main air outlet pipe or from the air outlet pipe, allowing the agglomerated raw materials to turn over, accelerating the filtration and disintegration speed of the agglomerated raw materials and the feed production efficiency, reducing the probability of agglomerated raw materials adhering to the filter screen for a long time and causing filter screen blockage, thereby improving the overall production quality and efficiency of feed.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1, see Figures 1 to 6 A livestock feed processing device includes a pneumatic conveying pump body 1, a conveying pipe 2 fixedly installed at the bottom end of the pneumatic conveying pump body 1, a filter screen 3 slidably installed on the inner wall of the conveying pipe 2, and the filter screen 3 is spherically shaped. A heating device adapted to the filter screen 3 is provided on the outside of the conveying pipe 2 to heat the raw materials passing through the filter screen 3, preventing the raw materials from adhering to the inner wall of the conveying pipe 2. Multiple filter screens 3 are provided. As the filter screen 3 gradually moves away from the storage bin for storing raw materials, the pore size of the filter screen 3 gradually decreases, so that the agglomerated raw materials pass through multiple filter screens 3 in sequence to meet the production requirements, preventing the agglomerated raw materials from staying at the filter screen 3 for a long time and causing the filter screen 3 to become clogged.

[0028] Please see Figure 2Multiple sliders 4 arranged in a circular array are fixedly installed on the outer side of the filter screen 3. A sliding groove is provided on the inner wall of the conveying pipe 2 to limit and slide the sliders 4. An elastic element 5 is fixedly installed on the side of the slider 4 away from the pneumatic conveying pump body 1 to reset the slider 4 after the agglomerated raw material is dispersed. Two support pipes 6 are symmetrically fixedly installed on the inner wall of the conveying pipe 2. The support pipes 6 are placed on the side of the filter screen 3 close to the pneumatic conveying pump body 1. The side of the support pipe 6 close to the filter screen 3 is fixedly connected to the main air outlet pipe 7, and the main air outlet pipe 7 is inclined. The end of the support pipe 6 away from the main air outlet pipe 7 is fixedly connected to the air inlet pipe 61. The ends of the multiple air inlet pipes 61 away from the support pipe 6 are connected to a high-pressure air pump through a connecting pipe. When the agglomerated raw material is intercepted by the filter screen 3, the high-pressure air pump sprays air towards the filter screen 3 through the support pipe 6 and the main air outlet pipe 7 to quickly break up the agglomerated raw material so that it meets the filtration requirements of the filter screen 3.

[0029] Please see Figures 2 to 4 An adjusting ring 8 is slidably installed on the inner wall of the support pipe 6. An arc-shaped baffle 9 is fixedly installed on the top of the adjusting ring 8. A spring 11 is fixedly installed between the bottom wall of the adjusting ring 8 and the inner bottom wall of the support pipe 6. Under the action of the spring 11, the adjusting ring 8 is positioned at the top of the support pipe 6, thereby preventing gas from entering the conveying pipe 2 through the support pipe 6 and the main exhaust pipe 7. A traction rope 10 is fixedly installed at the bottom of the adjusting ring 8. The end of the traction rope 10 away from the adjusting ring 8 moves through the bottom wall of the support pipe 6 and is fixedly connected to the filter screen 3. When agglomerated raw materials are intercepted by the filter screen 3, the agglomerated raw materials block the filter screen 3, increasing the force-bearing area of ​​the filter screen 3, thus making the filter... The filter screen 3 slides away from the pneumatic pump body 1. When the filter screen 3 slides, the adjusting ring 8 and the baffle 9 slide downward through the traction rope 10, and the spring 11 is compressed. At this time, the adjusting ring 8 and the baffle 9 are placed at the bottom of the support tube 6. The adjusting ring 8 no longer blocks the top of the support tube 6, so that the gas impacts and breaks up the agglomerated raw materials. The impact of the gas on the agglomerated raw materials reduces the probability that the raw materials will stay at the filter screen 3 for a long time, avoids the agglomerated raw materials from being heated and deteriorating due to prolonged stay, and also reduces the probability that the agglomerated raw materials will adhere to the filter screen 3 and cause the filter screen 3 to be blocked. This speeds up the filtration of agglomerated raw materials by the filter screen 3 and improves the production efficiency of the feed.

[0030] Please see Figures 2 to 6Multiple connecting rods 12 arranged in a ring array are fixedly installed on the side of the filter screen 3 away from the support pipe 6. A connecting shaft 13 is provided on the side of the connecting rod 12 away from the inner wall of the conveying pipe 2. A guide plate 14 is fixedly installed on the end of the connecting shaft 13 away from the connecting rod 12. One side of the guide plate 14 is a smooth surface, and the other side is an arc-shaped surface. When the gas conveying the raw material passes through the guide plate 14, the gas travels a longer distance along the arc-shaped surface, the flow rate is faster, and the gas pressure is lower, which creates a pressure difference between the smooth surface and the arc-shaped surface, thereby improving the conveying efficiency. A torsional force is applied to the filter screen 3 through the connecting shaft 13 and connecting rod 12 in the cross-sectional direction of the feed pipe 2. By setting the orientation of the arc surface on the guide plate 14, the torsional force applied to the filter screen 3 by each guide plate 14 is in a different direction, which causes the filter screen 3 to vibrate. The vibration of the filter screen 3 can help to break up the agglomerated raw materials when the high-pressure air pump pumps air into the feed pipe 2, and can also help to shake off the raw materials on the filter screen 3, thereby preventing the raw materials from adhering to the filter screen 3 and causing the pore size to become smaller, which would affect the conveying efficiency of the raw materials.

[0031] The filter screen 3 is spherical, which increases the filtration area. When the filter screen 3 is clogged by agglomerated raw materials, the force-bearing area is increased, allowing the agglomerated raw materials to accumulate in the concave areas of the filter screen 3. Normal, unagglomerated raw materials can be filtered out from the periphery of the filter screen 3. Since the guide plate 14 is placed on the side of the filter screen 3 away from the support tube 6, the guide plate 14 will not affect the filtration effect of the filter screen 3. The agglomerated raw materials that have been filtered by the filter screen 3 and have reduced in volume will not be intercepted by the guide plate 14 for a long time.

[0032] Please see Figure 5 The top end of the connecting shaft 13 movably passes through the bottom wall of the connecting rod 12 and is fixedly installed with a connecting plate 15. The connecting rod 12 has an internal movable groove 16 that matches the connecting plate 15, providing space for the connecting plate 15 to move. This allows the guide plate 14 to swing slightly in the horizontal direction when the gas passes through it, thus preventing the force balance between multiple guide plates 14, increasing the vibration frequency of the filter screen 3, and further enhancing the shaking effect of the raw material on the surface of the filter screen 3.

[0033] Example 2, please refer to Figure 3Two air outlet pipes 17 are symmetrically fixedly installed on the inner wall of the conveying pipe 2. The top of the air outlet pipe 17 is fixedly connected to the air inlet pipe 61. A pressure sensor is fixedly installed on the inner side wall of the slide groove away from the air outlet pipe 17. When the agglomerated raw material is intercepted by the filter screen 3, as the force-bearing area of ​​the filter screen 3 increases, the filter screen 3 and the agglomerated raw material intercepted by the filter screen 3 gradually slide away from the air inlet pipe 61. When the filter screen 3 slides, it drives the slider 4 to slide together. When the slider 4 slides in the slide groove to contact the pressure sensor, the pressure sensor transmits the pressure signal to the controller. The controller then converts the pressure signal into a control signal and starts the high-pressure air pump. The high-pressure air pump sprays air towards the filter screen 3 through the support pipe 6 and the main air outlet pipe 7 to quickly break up the agglomerated raw material so that it meets the filtration requirements of the corresponding filter screen 3.

[0034] A processing technology for livestock feed includes the following processing steps:

[0035] S1. When the raw materials in the storage bin are transported by the pneumatic conveying pump body 1, the raw materials that are damp and clumped together will be intercepted and broken by the filter screen 3.

[0036] S2. When the filter screen 3 is blocked by agglomerated raw materials, the force-bearing area increases. The filter screen 3 slides under force and drives the adjusting ring 8 and baffle 9 to slide through the traction rope 10, so as to release the blockage of the support pipe 6 by the adjusting ring 8, allowing gas to enter the interior of the conveying pipe 2 through the support pipe 6, and spray it onto the agglomerated raw materials through the main air outlet pipe 7 to impact and break them up.

[0037] S3. At the same time, when the gas flows through the guide plate 14, the pressure difference between the smooth surface and the arc-shaped surface of the gas in the guide plate 14 causes the filter screen 3 to be subjected to torsional forces in different directions in the cross-sectional direction, causing the filter screen 3 to vibrate to assist in breaking up the agglomerated raw materials on the filter screen 3.

[0038] Working principle:

[0039] When raw materials are transported from the storage bin via the pneumatic pump body 1 and the conveying pipe 2, the raw materials pass through the filter screen 3. When damp, clump-forming raw materials are intercepted by the filter screen 3, the clump-forming material obstructs the filter screen 3, increasing its contact area. This causes the filter screen 3 to slide away from the pneumatic pump body 1. As the filter screen 3 slides, the traction rope 10 drives the adjusting ring 8 and the baffle 9 downwards, compressing the spring 11. This prevents the adjusting ring 8 from blocking the top of the support pipe 6, allowing gas to enter the conveying pipe 2 through the support pipe 6 and the main exhaust pipe 7, impacting and breaking up the clump-forming raw materials. The impact of the gas on the clump-forming raw materials reduces the time the raw materials remain in the environment. The probability of clogging the filter screen 3 is reduced, which avoids the raw materials from being heated for a long time and thus deteriorating. It also reduces the probability of the raw materials clinging to the filter screen 3 and causing it to become clogged. This speeds up the filtration of the raw materials and improves the feed production efficiency. At the same time, when the gas flows through the guide plate 14, the pressure difference between the smooth surface and the curved surface causes the filter screen 3 to be subjected to torsional forces in different directions in the cross-sectional direction, which causes the filter screen 3 to vibrate. The vibration of the filter screen 3 can help break up the clogging raw materials when the high-pressure air pump pumps air into the conveying pipe 2. It can also help shake off the raw materials on the filter screen 3, thereby preventing the raw materials from adhering to the filter screen 3 and causing the pore size to become smaller, which would affect the conveying efficiency of the raw materials.

[0040] When agglomerated raw materials are intercepted on the surface of filter screen 3, the high-pressure air pump impacts and breaks up the agglomerated raw materials through the support pipe 6 and the main air outlet pipe 7 or through the air outlet pipe 17. During the process of intercepting and breaking up the agglomerated raw materials, the filter screen 3 not only achieves multi-stage filtration and breaking up of the agglomerated raw materials through multiple filter screens of different pore sizes, avoiding the agglomerated raw materials from staying on the filter screen 3 for a long time and causing the raw materials to deteriorate, but also accelerates the filtration and breaking up speed of the agglomerated raw materials through the impact of the gas, further improving the breaking up speed of the agglomerated raw materials. The impact of the gas on the agglomerated raw materials causes the raw materials to turn over, reducing the probability of the agglomerated raw materials adhering to the filter screen 3 for a long time and causing the filter screen 3 to become clogged, thus accelerating the filtration speed of the filter screen 3 on the agglomerated raw materials, thereby improving the overall production quality and efficiency of feed.
