Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment, and in particular to homogenizers. Background Technology

[0002] In the production processes of daily chemicals, chemicals, food, pharmaceuticals and other fields, homogenizers are equipment used to disperse, emulsify and refine materials. Homogenizers use a specific structure to rotate at high speed and act on the material to break up agglomerated particles and achieve dispersion, so as to meet the particle size requirements of subsequent production processes.

[0003] In existing technology, a homogenizer includes a motor that provides power, a main shaft that transmits power, grinding cutters that rotate with the main shaft, and a fixed grinding cylinder. When the homogenizer is started, the motor outputs power to drive the main shaft to rotate at high speed. The main shaft drives the grinding cutters to make circular motions within the crushing chamber. The material to be ground enters the crushing chamber from the feed structure at the top of the equipment and is driven by the high-speed rotating grinding cutters to form a high-speed material flow. During this process, the material is subjected to shearing action from the outer peripheral wall of the grinding cutters and impact and compression from the inner peripheral wall of the fixed grinding cylinder. At the same time, the material particles also collide with each other. These forces work together to gradually break up the agglomerated particles in the material, making the material particles finer. The ground material is discharged directly from the bottom of the crushing chamber under its own gravity and falls into a pre-set collection chamber at the bottom of the equipment or an external collection container, thus completing the grinding and collection process.

[0004] Regarding the aforementioned technologies, since the ground material is collected directly, some material may only undergo a brief grinding process and not be sufficiently sheared, impacted, and compressed before being discharged along with other materials. This results in a large number of insufficiently ground particles in the final collected material. This is especially true for coarse particles with larger initial particle sizes, which require stronger forces and longer grinding times to achieve the desired fineness. In the existing structure, if coarse particles are not sufficiently ground when they first pass through the crushing chamber, they will be directly mixed with the already refined material and collected together, causing uneven particle size distribution in the final material. The presence of coarse particles not only fails to meet the strict requirements for material particle size in subsequent production processes but may also affect subsequent processing steps, ultimately impacting product quality. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the purposes of this utility model is to provide a fine particle size homogenizer.

[0006] The fine particle size homogenizer provided in this application adopts the following technical solution:

[0007] The fine particle size homogenizer includes a motor, a main shaft, and a material container. The motor shaft of the motor is drivenly connected to the main shaft. A grinding cutter is provided at the end of the main shaft away from the motor. The grinding cutter is fixedly connected to the main shaft. A grinding cylinder is fixedly arranged around the outer periphery of the grinding cutter. A crushing chamber is formed between the grinding cutter and the grinding cylinder. The grinding cutter rotates around the main shaft in the crushing chamber. A through hole is opened at the bottom of the grinding cylinder. An inverted frustum-shaped screen, called a frustum screen, is installed in the material container. The grinding cylinder is located in the middle of the frustum screen.

[0008] The frustum screen is connected to the motor shaft via a speed-increasing and variable-speed mechanism.

[0009] The truncated cone screen uses a mesh size that meets the fineness requirements of the output material.

[0010] The frustum screen is provided with an outward flange above it, and an annular retaining edge fixed relative to the material container is provided outside the flange.

[0011] The height of the annular retaining edge is higher than the height of the frustum screen.

[0012] Below the annular retaining edge is a circular groove surrounding the lower outer side of the flange, which is called the recycling receiving platform;

[0013] The recycling receiving platform is inclined and has an opening on the lower side as a discharge port. The discharge port of the recycling receiving platform is connected to a material conveying mechanism. The discharge port of the material conveying mechanism is located above the grinding tool, forming a recycling and feeding system from the recycling receiving platform to the grinding tool.

[0014] By adopting the above technical solution, an inverted frustum screen is installed in the material container. The frustum screen is connected to the motor shaft through a speed-increasing mechanism. Together with the flange, annular guard, inclined recycling receiving platform and material conveying mechanism, a recycling and feeding system is formed. This effectively solves the problem of insufficient grinding and coarse particle mixing caused by direct collection of materials in the homogenizer in the existing technology.

[0015] The size of the circular screen mesh matches the required fineness of the output, enabling precise screening of fine particle size materials. The speed-increasing mechanism drives the screen to rotate at high speed, using centrifugal force to improve screening efficiency and reduce clogging. Coarse particles that do not pass through the screen flow outward under the guidance of centrifugal force and the flange. The annular baffle prevents them from splashing and allows them to fall into the recycling receiving platform. The inclined receiving platform guides the coarse particles into the material conveying mechanism by gravity, and finally sends them back to the crushing chamber above the grinding cutter for secondary grinding.

[0016] This closed-loop design can complete the cyclic grinding of coarse particles without manual intervention, ensuring that all discharged materials meet the requirements for fine particle size, improving the uniformity of product particle size, and avoiding the increase in workload and production interruption caused by manual secondary feeding.

[0017] Preferably, at least three first connecting rods are provided on the outer periphery of the grinding cylinder, which are evenly distributed along the circumference of the outer wall of the grinding cylinder, and the end of the first connecting rod away from the grinding cylinder is fixedly connected to the inner wall of the material container.

[0018] At least three second connecting rods are provided on the outer periphery of the annular retaining edge, which are evenly distributed along the circumference of the annular retaining edge. The end of the second connecting rod away from the annular retaining edge is fixedly connected to the inner wall of the material container.

[0019] At least three third connecting rods are provided on the outer periphery of the recycling receiving platform, which are evenly distributed along the circumference of the recycling receiving platform. The end of the third connecting rod away from the recycling receiving platform is fixedly connected to the inner wall of the material container.

[0020] By adopting the above technical solution, a first connecting rod is provided on the outer periphery of the grinding cylinder, a second connecting rod is provided on the outer periphery of the annular baffle, and a third connecting rod is provided on the outer periphery of the recycling receiving platform. Each connecting rod is evenly distributed along the circumference of the corresponding component and is fixedly connected to the inner wall of the material container. This can ensure that the grinding cylinder, the annular baffle, and the recycling receiving platform are in stable positions during equipment operation, and avoid component displacement or loosening caused by vibration generated by the high-speed rotation of the grinding cutter and the circular screen.

[0021] Preferably, at least four blades are evenly arranged on the outer periphery of the grinding tool, the blades are located in the crushing chamber, and the blades rotate coaxially with the grinding tool;

[0022] The grinding cylinder has a cylindrical structure, and at least 10 long grooves are evenly arranged on the inner side wall of the grinding cylinder. The length direction of the long grooves is the same as the axial direction of the main shaft, forming a guide groove.

[0023] By adopting the above technical solution, when the blade rotates coaxially with the grinding tool, it forms a stronger shearing effect with the fixed grinding cylinder, while the axial guide groove can guide the material to flow along the main shaft axis, breaking the limitation that the material in the traditional homogenizer only moves in the circumferential direction.

[0024] The material is subjected to shearing force from the blades in the crushing chamber, and it also repeatedly impacts and is squeezed against the walls of the guide channel. This increases the frequency of contact between the material and the grinding components, effectively improving the material refining efficiency. At the same time, it avoids uneven grinding caused by the single movement path of local materials, further ensuring that the material particle size can meet the fine particle size requirements.

[0025] Preferably, the blade and the grinding tool are integrally formed.

[0026] By adopting the above technical solution, the blade and grinding tool are integrally formed, which significantly enhances the overall structural strength of the blade and grinding tool compared with the traditional assembled blade. The integral forming design eliminates assembly gaps, which not only avoids the blade from loosening or breaking due to material impact during high-speed rotation, reducing the frequency of equipment maintenance, but also prevents cleaning problems caused by residual material in the assembly gaps, ensuring the cleanliness of the material during the grinding process.

[0027] Preferably, an annular plate-shaped structure, referred to as a pressure plate, is provided above the grinding tool; a fixing bolt is provided above the pressure plate, the fixing bolt passes through the pressure plate and is threaded to the spindle.

[0028] By adopting the above technical solution, the pressure plate and fixing bolt structure form an axial limiting mechanism for the grinding tool, which prevents the grinding tool from axially moving during high-speed rotation. In turn, by stabilizing the cooperation between the grinding tool and the spindle, the uniformity of material tumbling and the stability of shearing are enhanced, ultimately ensuring the material refining effect.

[0029] Specifically, the fixing bolt passes through the pressure plate and forms a threaded connection with the main shaft. After tightening, it can firmly press the pressure plate above the grinding tool, providing a continuous and stable axial downward constraint force for the grinding tool. This effectively counteracts the upward tendency of the grinding tool caused by centrifugal force and material impact when it rotates at high speed, ensuring that the grinding tool is always in the preset axial position throughout the entire working process, so that the material can be fully tumbled and sheared.

[0030] Preferably, the grinding tool is sleeved on the outer periphery of the spindle, and the inner sidewall of the grinding tool is provided with a strip-shaped groove; a plate-shaped structure is provided between the fixing bolt and the pressure plate, which is called a safety component. One end of the safety component is bent upward along the axial direction of the spindle and abuts against the fixing bolt. The safety component is bent downward along the axial direction of the spindle away from the upward bent end and embedded in the strip-shaped groove.

[0031] By adopting the above technical solution, one end of the safety component is bent upward along the spindle axis to abut against the fixing bolt, and the other end is bent downward to abut against the inner wall of the grinding tool, so that the grinding tool can rotate coaxially with the spindle in both positive and negative directions.

[0032] Meanwhile, the safety device is located between the fixing bolt and the pressure plate, which can limit the safety device and prevent the grinding tool from axially moving due to centrifugal force or material impact when the spindle rotates at high speed. This would result in insufficient tumbling of the material in the upper and lower disturbance areas, leading to unstable material shearing effect.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. An inverted frustum screen is installed in the material container. The frustum screen is connected to the motor shaft through a speed-increasing mechanism. Together with the flange, the annular guard, the inclined recycling receiving platform and the material conveying mechanism, it forms a recycling and feeding system. This can effectively solve the problem of insufficient grinding and coarse particles being mixed in due to the direct collection of materials in the homogenizer in the existing technology.

[0035] The size of the circular screen mesh matches the required fineness of the output, enabling precise screening of fine particle size materials. The speed-increasing mechanism drives the screen to rotate at high speed, using centrifugal force to improve screening efficiency and reduce clogging. Coarse particles that do not pass through the screen flow outward under the guidance of centrifugal force and the flange. The annular baffle prevents them from splashing and allows them to fall into the recycling receiving platform. The inclined receiving platform guides the coarse particles into the material conveying mechanism by gravity, and finally sends them back to the crushing chamber above the grinding cutter for secondary grinding.

[0036] This closed-loop design can complete the cyclic grinding of coarse particles without manual intervention, ensuring that all discharged materials meet the requirements for fine particle size, improving the uniformity of product particle size, and avoiding the increase in workload and production interruption caused by manual secondary feeding.

[0037] 2. A first connecting rod is provided on the outer periphery of the grinding cylinder, a second connecting rod is provided on the outer periphery of the annular retaining edge, and a third connecting rod is provided on the outer periphery of the recycling receiving platform. Each connecting rod is evenly distributed along the circumference of the corresponding component and is fixedly connected to the inner wall of the material container. This ensures that the grinding cylinder, the annular retaining edge, and the recycling receiving platform are in stable position during equipment operation, and avoids component displacement or loosening caused by vibration generated by the high-speed rotation of the grinding cutter and the circular screen.

[0038] 3. When the blade rotates coaxially with the grinding tool, it forms a stronger shearing effect with the fixed grinding cylinder, while the axial guide groove can guide the material to flow along the main shaft axial direction, breaking the limitation of material only moving in the circumferential direction in traditional homogenizers.

[0039] The material is subjected to shearing force from the blades in the crushing chamber, and it also repeatedly impacts and is squeezed against the walls of the guide channel. This increases the frequency of contact between the material and the grinding components, effectively improving the material refining efficiency. At the same time, it avoids uneven grinding caused by the single movement path of local materials, further ensuring that the material particle size can meet the fine particle size requirements.

[0045] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0046] This application discloses a fine particle size homogenizer.

[0047] Reference Figure 1 and Figure 2 The fine particle size homogenizer includes a motor 1, a main shaft 2, and a material container 3. The motor shaft of the motor 1 is connected to the main shaft 2 for transmission. To ensure the stability and coaxiality of the transmission between the two, a set screw is provided at the connection between the motor 1 and the main shaft 2. The set screw fixes the motor shaft of the motor 1 and the main shaft 2, which can control the runout of the main shaft 2 to less than or equal to 0.02mm, so as to achieve stable coaxial transmission between the motor 1 and the main shaft 2. A grinding cutter 4 is provided at the end of the main shaft 2 away from the motor 1. The grinding cutter 4 is fixedly connected to the main shaft 2, specifically, the grinding cutter 4 is sleeved on the outer periphery of the main shaft 2. A grinding cylinder 5 is fixedly provided on the outer periphery of the grinding cutter 4. The grinding cylinder 5 has a cylindrical structure. At least three first connecting rods 12 are provided on the outer periphery of the grinding cylinder 5, which are evenly distributed along the outer wall of the grinding cylinder 5. The end of the first connecting rod 12 away from the grinding cylinder 5 is fixedly connected to the inner wall of the material container 3. The grinding cylinder 5 is stably positioned in the material container 3 through the first connecting rods 12. A crushing chamber for grinding materials is formed between the grinding cutter 4 and the grinding cylinder 5. The grinding cutter 4 rotates around the main shaft 2 in the crushing chamber, so that the material is ground by rotating and tumbling in the crushing chamber. A through hole is opened at the bottom of the grinding cylinder 5. The ground material will be discharged directly from the through hole at the bottom of the grinding cylinder 5 under its own gravity.

[0048] A truncated cone-shaped screen, called a truncated cone screen 6, is installed in the material container 3. The truncated cone screen 6 is connected to the motor shaft through a speed-increasing mechanism 7. The mesh size of the truncated cone screen 6 is set according to the fineness requirements of the output material to ensure that the particle size of the material passing through the screen meets the fine particle size requirements. The grinding cylinder 5 is located in the middle of the truncated cone screen 6, specifically, the axis of the truncated cone screen 6 coincides with the axis of the grinding cylinder 5, and the top of the grinding cylinder 5 is higher than the top of the truncated cone screen 6. Gaps are left between the bottom of the grinding cylinder 5 and the screen of the truncated cone screen 6, and between the outer wall of the grinding cylinder 5 and the inner wall of the truncated cone screen 6, to avoid frictional contact between the grinding cylinder 5 and the truncated cone screen 6 during the rotation of the truncated cone screen 6. At the same time, the material screened by the truncated cone screen 6 is discharged from the mesh of the screen into the material container 3.

[0049] Above the frustum screen 6, at the end with the larger radius of the inverted frustum screen 6, there is an outwardly extending flange 8. This flange 8 is used to guide coarse particles that have not passed through the screen to flow outward. Outside the flange 8, there is an annular baffle 9 fixed relative to the material container 3. At least three second connecting rods 13 are evenly distributed around the annular baffle 9. The annular baffle 9 is fixedly connected to the inner wall of the material container 3 through the evenly distributed second connecting rods 13. The height of the annular baffle 9 is higher than the height of the frustum screen 6 to prevent coarse particles from splashing out of the annular baffle 9 from the outside of the flange 8 under the action of centrifugal force.

[0050] Below the annular retaining edge 9, there is an annular groove surrounding the lower outer side of the flange 8. This annular groove is called the recycling receiving platform 10. At least three third connecting rods 14 are evenly distributed around the circumference of the recycling receiving platform 10. The end of the third connecting rod 14 away from the recycling receiving platform 10 is fixedly connected to the inner wall of the material container 3 to ensure the stability of the recycling receiving platform 10. The recycling receiving platform 10 is inclined at an angle of 15°. An opening is provided on the lower side of the recycling receiving platform 10 as a discharge port. The discharge port is connected to a material conveying mechanism 11. In this embodiment, the material conveying mechanism 11 includes a conveying pipe and a pump. The feed end of the material conveying mechanism 11 is fixedly connected to the discharge port of the recycling receiving platform 10. The discharge end of the material conveying mechanism 11 extends above the grinding blade 4 and corresponds to the feed area of ​​the crushing chamber, forming a recycling feeding system from the recycling receiving platform 10 to the grinding blade 4, so that coarse particles that have not passed through the screen can re-enter the crushing chamber for secondary grinding.

[0051] Reference Figure 2 , Figure 3 and Figure 4At least four blades 15 are evenly arranged along the circumference of the grinding cutter 4. The blades 15 are located inside the crushing chamber and rotate coaxially with the grinding cutter 4 and the main shaft 2. Preferably, the blades 15 and the grinding cutter 4 are integrally formed. This integral structure can significantly improve the overall structural strength of the blades 15 and the grinding cutter 4, preventing the blades 15 from loosening or breaking due to material impact during high-speed rotation. At the same time, the grinding cylinder 5 has a cylindrical structure. At least 10 long grooves are evenly arranged along the circumference of the inner wall of the grinding cylinder 5. The length direction of the long grooves is the same as the axial direction of the main shaft 2, forming a guide groove 16. The guide groove 16 can guide the material to flow along the axial direction of the main shaft 2 and, together with the thrust of the blades 15 on the material, form a shearing effect. The dense guide grooves 16 greatly increase the contact area between the grinding cylinder 5 and the material, causing the material to repeatedly collide and squeeze against the groove wall during the flow, significantly increasing the shearing frequency.

[0052] A ring-shaped plate structure, called pressure plate 17, is provided above the grinding cutter 4. A fixing bolt 18 is provided above the pressure plate 17. The fixing bolt 18 passes through a preset through hole in the pressure plate 17 and is threadedly connected to the preset internal thread hole at the upper end of the spindle 2. After tightening the fixing bolt 18, the lower end face of the pressure plate 17 is tightly fitted with the upper end face of the grinding cutter 4, providing a continuous and stable axial downward constraint force for the grinding cutter 4. This can effectively counteract the upward tendency of the grinding cutter 4 caused by centrifugal force and material impact when it rotates at high speed, ensuring that the grinding cutter 4 is always in the preset axial position and providing a stable tumbling and shearing environment for the material.

[0053] Furthermore, a strip-shaped groove 19 is provided on the inner wall of the grinding cutter 4; a plate-like structure, called a safety element 20, is provided between the fixing bolt 18 and the pressure plate 17. The safety element 20 has a through hole in the middle for the fixing bolt 18 to pass through. One end of the safety element 20 is bent upward at 90 degrees along the axial direction of the main shaft 2, and this upward bend abuts against the fixing bolt 18. The other end of the safety element 20, away from the upward bend, is bent downward at 90 degrees along the axial direction of the main shaft 2, and the downward bend is embedded in and abuts against the strip-shaped groove 19 on the inner wall of the grinding cutter 4. The bending structure of the safety element 20 allows the grinding cutter 4 to rotate coaxially with the main shaft 2 in both directions. At the same time, it works in conjunction with the pressure plate 17 to prevent the grinding cutter 4 from moving axially, thereby avoiding the problem of uneven material refinement caused by insufficient or excessive local shear force in the grinding chamber.

[0054] The implementation principle of this application embodiment is as follows:

[0055] When this fine particle size homogenizer is working, the material to be processed enters the crushing chamber from the feed area at the top of the material container 3. The motor 1 drives the motor shaft to rotate, and the motor shaft simultaneously drives the main shaft 2 and the speed-increasing mechanism 7 to rotate. The main shaft 2 drives the grinding cutter 4 and the blade 15 to rotate at high speed in the crushing chamber, performing shearing, impact crushing and grinding on the material. The guide groove 16 on the inner side wall of the grinding cylinder 5 guides the material to flow axially, improving the uniformity of crushing.

[0056] The crushed material enters the frustum screen 6 area through the through hole at the bottom of the grinding cylinder 5. The high-speed rotating frustum screen 6 generates centrifugal force, and fine particles that meet the fineness requirements fall through the screen mesh into the bottom of the material container 3. Coarse particles that do not pass through the screen flow outward under the guidance of centrifugal force and the flange 8, and fall into the recycling receiving platform 10 below after being blocked by the annular baffle 9. The inclined recycling receiving platform 10 causes the coarse particles to slide to the lower discharge port under the action of gravity and enter the material conveying mechanism 11. The material conveying mechanism 11 transports the coarse particles to the top of the grinding cutter 4 and re-enters the crushing chamber for secondary grinding. This cycle continues until all materials have passed through the frustum screen 6, finally achieving uniform particle size of the material.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
