Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of biological feed production equipment, specifically to a raw material crushing device for biological feed production. Background Technology
[0002] In the production of bio-feed, raw material crushing is a crucial process that directly impacts the quality and efficiency of subsequent processing. Existing raw material crushing equipment typically employs a single mechanical structure for crushing operations. While this meets basic crushing requirements, it has several shortcomings in practical applications. For example, mechanical friction and material collisions during crushing generate significant heat, leading to elevated internal temperatures. This can affect the physical and chemical properties of the raw materials and potentially cause overheating, reducing the equipment's lifespan. Furthermore, existing equipment often features fixed screening mechanisms, resulting in low screening efficiency and a susceptibility to clogging, making it difficult to meet the requirements of high-efficiency production and refined processing. Additionally, some equipment has complex structures, making maintenance inconvenient and increasing production costs and operational difficulty. Therefore, effectively addressing the temperature rise issue during crushing, improving screening efficiency, and optimizing the overall equipment structure have become pressing technical challenges in the bio-feed production field. This application aims to provide a high-efficiency, stable, and easy-to-maintain raw material crushing device for bio-feed production through an innovative double-layer cooling structure and dynamic screening design, overcoming the shortcomings of existing technologies. Utility Model Content
[0003] This invention addresses the shortcomings of existing raw material grinding equipment for bio-feed production in terms of grinding efficiency, temperature control, and particle size screening, and provides a structurally optimized raw material grinding device for bio-feed production. Through a double-layer structural design, integrated cooling system, and the synergistic effect of a dynamic screening mechanism, the device solves the problems of raw material deterioration or shortened equipment lifespan caused by high temperatures in traditional equipment, while simultaneously achieving precise control over the particle size of the ground raw materials.
[0004] This utility model provides a raw material crushing equipment for biological feed production, including a crushing tank, a feeding hopper, a stainless steel discharge pipe, a support, a crushing mechanism, a raw material screening mechanism, and an auxiliary stabilizing structure.
[0005] in:
[0006] The pulverizing tank adopts a double-layer structure design, with a cavity formed between the inner and outer layers. A cooling pipe is spirally arranged inside the cavity. One end of the cooling pipe is fixed with a refrigerant input pipe, and the other end is fixed with a heat medium output pipe. The ends of both the refrigerant input pipe and the heat medium output pipe penetrate the pulverizing tank and extend to the outside for connection with an external cooling system, thereby achieving effective heat removal during the pulverizing process.
[0007] Furthermore, the feed hopper extends through and is fixed to the top of the crushing tank, and is used to uniformly input the raw material to be crushed into the crushing tank. The design of the feed hopper ensures the smooth flow of the raw material into the crushing tank and avoids affecting the crushing efficiency due to accumulation.
[0008] Specifically, the stainless steel discharge pipe runs through and is fixed to the bottom right side of the grinding tank to discharge the ground raw materials. The choice of stainless steel ensures the corrosion resistance and durability of the pipe. A raw material screening mechanism is installed at the end of the stainless steel discharge pipe to screen the ground raw materials by particle size, meeting the requirements for uniform particle size in bio-feed production.
[0009] Furthermore, the bottom of the pulverizing tank is supported and fixed by at least two brackets. The number and distribution of the brackets are determined according to the overall weight of the equipment and the vibration characteristics during operation, so as to ensure the stability of the equipment during operation.
[0010] The crushing mechanism includes a crushing motor fixed to the left side of the crushing tank. The output end of the crushing motor passes through the crushing tank and is fixed to a main shaft. Evenly distributed crushing blades are fixed on the outer diameter of the main shaft. The crushing motor drives the main shaft to rotate, and the main shaft drives the crushing blades to rotate at high speed, thereby efficiently crushing the raw materials.
[0011] Furthermore, the raw material screening mechanism includes a conical screening chamber located at the end of a stainless steel discharge pipe. The surface of the conical screening chamber has evenly distributed screening holes for screening the pulverized raw materials. The end of the stainless steel discharge pipe rotates relative to the conical screening chamber via a bearing, allowing the pulverized raw materials to flow smoothly into the conical screening chamber. A driven pulley is fixed to the left side of the outer diameter of the conical screening chamber, and a drive motor is fixed to the right side of the pulverizing chamber. A drive pulley is fixed to the output end of the drive motor, and the drive pulley and the driven pulley are connected by a connecting belt drive, thereby driving the conical screening chamber to rotate. The rotating conical screening chamber improves screening efficiency and ensures the uniformity of particle size of the pulverized raw materials through dynamic screening.
[0012] Specifically, a rotating ring is rotatably connected to the right side of the outer diameter of the conical screening chamber. The outer diameter of the rotating ring is connected to the rightmost support via two connecting strips. The design of the rotating ring and connecting strips enhances the stability of the conical screening chamber and effectively reduces vibration during equipment operation.
[0013] Furthermore, the right side of the conical screening chamber is open, and it can be opened and closed by rotating a sealed door and a handle, facilitating cleaning of the screening chamber. The sealed door design ensures the airtightness of the equipment during operation, while also facilitating maintenance.
[0014] This invention solves the problem of raw material deterioration and shortened equipment lifespan caused by high-temperature environments in existing crushing equipment through the above-mentioned technical solution. The double-layer structure design of the crushing tank and the arrangement of cooling pipes, with the cooling medium introduced through a refrigerant inlet pipe and the heated medium discharged through a heat outlet pipe, effectively control the heat generated during the crushing process. The optimized flow path of the cooling medium ensures that the cooling effect evenly covers the entire inner wall of the crushing tank, thereby avoiding localized overheating.
[0015] Furthermore, the design of the crushing mechanism enables highly efficient crushing of raw materials. The crushing motor drives the main shaft to rotate at high speed, and the crushing blades on the main shaft apply shearing and impact forces to the raw materials, enabling them to reach the required particle size in a short time.
[0016] Specifically, the raw material screening mechanism is designed to achieve dynamic screening of the pulverized raw materials. A drive motor rotates the conical screening chamber via belt drive. During rotation, the raw material is evenly distributed on the surface of the screening holes under centrifugal force. Raw materials that do not meet the particle size requirements are retained in the screening chamber for further screening, while those that meet the requirements are discharged through the screening holes. The size and distribution of the screening holes are optimized to meet the needs of bio-feed production with different particle size requirements.
[0017] Furthermore, the design of the rotating ring and connecting bar enhances the stability of the conical screening chamber. The rotating ring is connected to the support frame via the connecting bar, forming a stable support structure that effectively reduces vibration during equipment operation, thereby extending the equipment's service life.
[0018] Specifically, the design of the sealing door and handle facilitates cleaning and maintenance of the conical screening chamber. The sealing door opens by rotation, allowing operators to quickly remove residues from the screening chamber. The sealing structure between the sealing door and the conical screening chamber is made of high-temperature and corrosion-resistant materials, ensuring the equipment's sealing performance in high-temperature environments.
[0019] In summary, this invention significantly improves the performance of raw material grinding equipment for bio-feed production through its dual-layer structure design, integrated cooling system, and the synergistic effect of its high-efficiency grinding mechanism and dynamic screening mechanism. The equipment exhibits excellent performance in grinding efficiency, temperature control, and particle size screening, making it suitable for large-scale industrial production and possessing significant application value.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a raw material crushing device for biological feed production, the structural design and functional implementation of which are described in detail with reference to the accompanying drawings. The specific embodiments of this utility model will be described in detail below with reference to the specific component reference numerals in the drawings and the actual operating principle and process of the equipment.
[0028] like Figures 1 to 5 As shown, the raw material grinding equipment for biological feed production of this utility model includes a grinding tank 1, a feeding hopper 2, a stainless steel discharge pipe 3, a support 4, a grinding mechanism, a raw material screening mechanism, and other auxiliary stabilizing structures. These components, through optimized design, achieve efficient grinding, precise temperature control, and uniform particle size screening. The following provides a detailed description of the specific structure and operating principle of each component.
[0029] The pulverizing tank 1 adopts a double-layer structure design, with a cavity formed between the inner and outer layers. A cooling pipe 11 is spirally arranged inside this cavity. One end of the cooling pipe 11 is fixedly connected to a refrigerant inlet pipe 12, and the other end is fixedly connected to a heat medium outlet pipe 13. Both the refrigerant inlet pipe 12 and the heat medium outlet pipe 13 penetrate the pulverizing tank 1 and extend to the outside for connection with an external cooling system. The cooling medium enters the cooling pipe 11 from the refrigerant inlet pipe 12 and flows along a spiral path, absorbing the heat generated during the pulverizing process. The heated medium is then discharged through the heat medium outlet pipe 13. This design ensures that the cooling effect evenly covers the entire inner wall of the pulverizing tank, preventing localized overheating. In practical applications, the cooling medium can be liquids such as water or antifreeze; the appropriate type of medium is selected based on the ambient temperature and equipment usage requirements.
[0030] The feed hopper 2 penetrates and is fixed to the top of the grinding tank 1, and is used to evenly feed the raw material to be ground into the grinding tank. The design of the feed hopper 2 ensures smooth entry of the raw material into the grinding tank, while preventing accumulation that could affect grinding efficiency. After entering from the feed hopper 2, the raw material falls directly into the grinding tank 1, where it is efficiently processed by the grinding mechanism. The opening size of the feed hopper 2 can be adjusted according to the particle size of the raw material to accommodate different types of raw materials.
[0031] A stainless steel discharge pipe 3 runs through and is fixed to the bottom right side of the grinding tank 1 for discharging the ground raw materials. The choice of stainless steel enhances the corrosion resistance and durability of the pipe, extending the service life of the equipment. A conical screening chamber 6 is located at the end of the stainless steel discharge pipe 3 for particle size screening of the ground raw materials. The end of the stainless steel discharge pipe 3 rotates relative to the conical screening chamber 6 via a bearing 31, allowing the ground raw materials to flow smoothly into the conical screening chamber 6. The surface of the conical screening chamber 6 has evenly distributed screening holes, the size and distribution of which are optimized to meet the needs of biological feed production with different particle size requirements. A passive pulley 61 is fixed to the left side of the outer diameter of the conical screening chamber 6, and a drive motor 62 is fixed to the right side of the grinding tank 1. A drive pulley 63 is fixed to the output end of the drive motor 62, and the drive pulley 63 and the passive pulley 61 are connected by a connecting belt 64. The drive motor 62 drives the drive pulley 63 to rotate, transmitting power to the passive pulley 61 through the connecting belt 64, thereby driving the conical screening chamber 6 to rotate. The rotating conical screening chamber 6 improves screening efficiency through dynamic screening of raw materials, while ensuring the uniformity of particle size after crushing. During actual operation, the rotation speed of the conical screening chamber 6 can be adjusted according to the characteristics of the raw materials to achieve the best screening effect.
[0032] The bottom of the crushing tank 1 is supported and fixed by at least two supports 4. The number and distribution of supports 4 are determined according to the overall weight of the equipment and the vibration characteristics during operation to ensure the stability of the equipment during operation. The design of the supports 4 not only considers the static stability of the equipment, but also takes into account the vibration problems that may occur during the operation of the equipment, effectively reducing the shaking amplitude of the equipment during operation.
[0033] The pulverizing mechanism includes a pulverizing motor 5 fixed to the left side of the pulverizing tank 1. The output end of the pulverizing motor 5 passes through the pulverizing tank 1 and is fixed to a main shaft 51. Uniformly distributed pulverizing blades 52 are fixed on the outer diameter of the main shaft 51. The pulverizing motor 5 drives the main shaft 51 to rotate at high speed. The main shaft 51 drives the pulverizing blades 52 to apply shearing and impact forces to the raw material, enabling the raw material to reach the required particle size in a short time. In actual operation, the power and speed of the pulverizing motor 5 can be adjusted according to the hardness of the raw material and the required particle size to achieve the best pulverizing effect.
[0034] A rotating ring 7 is rotatably connected to the right side of the outer diameter of the conical screening chamber 6. The outer diameter of the rotating ring 7 is connected to the rightmost support 4 via two connecting bars 71. The design of the rotating ring 7 and connecting bars 71 enhances the stability of the conical screening chamber 6 and effectively reduces vibration during equipment operation. This design not only improves the overall rigidity of the equipment but also extends its service life. The right side of the conical screening chamber 6 is open, and it is opened and closed by rotating a sealing door 8 and a handle 81. The design of the sealing door 8 facilitates quick cleaning of residues inside the screening chamber by operators while ensuring the airtightness of the equipment during operation. The sealing structure between the sealing door 8 and the conical screening chamber 6 is made of high-temperature and corrosion-resistant materials, which can maintain good sealing performance in high-temperature environments.
[0035] In actual operation, the raw material crushing equipment for biological feed production of this utility model completes the crushing and screening of raw materials according to the following steps: S1, start the equipment and check whether the cooling system is operating normally, ensuring that the refrigerant inlet pipe 12 and the heat outlet pipe 13 are connected correctly. S2, evenly feed the raw material to be crushed into the crushing tank 1 from the feed hopper 2. S3, start the crushing motor 5, drive the main shaft 51 to drive the crushing blades 52 to rotate at high speed, and perform efficient crushing of the raw material. S4, the crushed raw material is discharged into the conical screening chamber 6 through the stainless steel discharge pipe 3. S5, start the drive motor 62, drive the conical screening chamber 6 to rotate through the active pulley 63, the connecting belt 64 and the passive pulley 61, and perform dynamic screening of the raw material. S6, the raw material that meets the particle size requirements is discharged through the screening holes on the surface of the conical screening chamber 6, and the raw material that does not meet the particle size requirements continues to remain in the screening chamber for further screening. S7, periodically open the sealing door 8 to clean the residue in the screening chamber to ensure the long-term stable operation of the equipment.
[0036] In summary, this invention significantly improves the performance of raw material grinding equipment for bio-feed production through its dual-layer structure design, integrated cooling system, and the synergistic effect of its high-efficiency grinding mechanism and dynamic screening mechanism. The equipment exhibits excellent performance in grinding efficiency, temperature control, and particle size screening, making it suitable for large-scale industrial production scenarios.
