Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, and more specifically, to a particulate material processing device. Background Technology

[0002] With the increasing demand for industrial automation and precision manufacturing, particulate material processing equipment is playing an increasingly important role in various fields such as chemical, pharmaceutical, and food processing. The main function of these devices is to process raw materials into particles with specific shapes and sizes to meet the needs of subsequent processes.

[0003] Taking the shaping and preparation of spherical graphite as an example, existing natural graphite shaping processes often require multiple crushing, spheroidizing, and grading processes to produce spherical graphite. For example, 60, 50, and 30 mills all have a tailings grading system, which discharges micro powder during the crushing and shaping process, resulting in the generation of tailings. The tailings account for nearly half of the total, so the yield of spherical graphite is generally around 50%. The value of the tailings differs greatly from that of spherical graphite, leading to a significant reduction in production efficiency.

[0004] As can be seen from the above, the existing technology has the problem of excessive waste material generated after processing granular materials. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a particulate material processing device, comprising: a crushing assembly, which includes a first cylinder, a crushing component, and a classifying impeller. The crushing component is rotatably disposed in the lower part of the first cylinder for crushing particulate materials, and the classifying impeller is disposed in the upper part of the first cylinder for classifying the crushed particulate materials; and a shaping assembly, which includes a second cylinder and a shaping disc. The second cylinder is connected to the first cylinder, and the shaping disc is rotatably disposed in the second cylinder for shaping the classified particulate materials.

[0007] Furthermore, the crushing component includes hammers and a hammer disk. There are multiple hammers, which are spaced apart on the top surface of the hammer disk along the circumference. At least a portion of each hammer protrudes from the outer periphery of the hammer disk. The hammer disk is horizontally rotatable, and a crushing area is formed between the crushing component and the inner wall of the first cylinder.

[0008] Furthermore, the crushing assembly also includes a first liner plate, which is disposed on the inner wall surface of the first cylinder and correspondingly disposed with respect to the crushing component. The first liner plate includes a plurality of first grinding columns, which are arranged circumferentially along the inner wall surface of the first cylinder, and a crushing area is formed between the crushing component and the first liner plate.

[0009] Furthermore, the minimum gap L between the hammer and the first liner plate and the diameter L of the hammer disk satisfy the following condition: 0.045≤L1 / L2≤0.089.

[0010] Furthermore, the hammerhead has protrusions on its end face protruding from the outer periphery of the hammerhead disc. There are multiple protrusions, which are spaced apart.

[0011] Furthermore, the shaping component also includes shaping balls, and there are multiple shaping balls that are movably distributed between the inner wall surfaces of the shaping disk and the second cylinder.

[0012] Furthermore, the shaping assembly also includes a second liner plate, which is disposed on the inner wall surface of the second cylinder and corresponding to the shaping disc. The second liner plate includes a plurality of second grinding columns, which are arranged circumferentially along the inner wall surface of the second cylinder, and a shaping area is formed between the shaping disc and the second liner plate.

[0013] Furthermore, the particulate material processing apparatus also includes a liquid addition component, which is connected to the second cylinder and is used to add a binder for bonding the particulate material into the second cylinder.

The spray section is located between the shaping disc and the inner wall of the second cylinder and is parallel to the rotation axis of the shaping disc. There are multiple nozzles, which are spaced apart in the spray section.

[0016] The granular material processing device using the technical solution of this utility model includes a crushing component and a shaping component. The crushing component includes a first cylinder, a crushing element, and a classifying impeller. The crushing element is rotatably disposed in the lower part of the first cylinder for crushing the granular material.

This interconnected crushing component... In the shaping component, the granular material is first circulated and pulverized in the first cylinder of the pulverizing component.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] To address the problem of excessive waste material generated after processing granular materials in existing technologies, this invention provides a granular material processing device.

[0031] The following will use the shaping and preparation of spherical graphite as an example to specifically describe the particulate material processing apparatus and process of this application. That is, in this embodiment, the particulate material processing apparatus is a spherical graphite shaping and preparation apparatus. It can be understood that when spherical graphite is shaped and prepared, the particulate material to be processed is graphite powder. Of course, the particulate material processing apparatus can also be an apparatus for other purposes, and can be selected according to actual needs.

[0032] like Figures 1 to 4As shown, the particulate material processing device includes a crushing assembly 100 and a shaping assembly 200. The crushing assembly 100 includes a first cylinder 29, a crushing component, and a classifying impeller 7. The crushing component is rotatably disposed in the lower part of the first cylinder 29 for crushing the particulate material. The classifying impeller 7 is disposed in the upper part of the first cylinder 29 for classifying the crushed particulate material. The shaping assembly 200 includes a second cylinder 12 and a shaping disc 16. The second cylinder 12 communicates with the first cylinder 29, and the shaping disc 16 is rotatably disposed within the second cylinder 12 for shaping the classified particulate material.

[0033] This application utilizes a connected crushing component 100 and a shaping component 200. The particulate material is first circulated and crushed within the first cylinder 29 of the crushing component 100. Qualified fine particles are discharged to the shaping component 200 via the airflow through the classifying impeller 7, while unqualified coarse particles are thrown back to the lower part of the first cylinder 29 by the classifying impeller 7 under centrifugal force for further crushing. This achieves ultrafine crushing of the particulate material. The crushed particulate material then enters the shaping component 200 for shaping, ultimately forming spherical small-diameter particles. This eliminates tailings during the entire processing, significantly improving the yield of particulate material and increasing production efficiency.

[0034] like Figure 2 As shown, the crushing component includes hammerheads 3 and hammerhead discs 4. There are multiple hammerheads 3, which are spaced apart along the circumference of the hammerhead disc 4 on the top surface of the hammerhead disc 4, and at least a portion of each hammerhead 3 protrudes from the outer periphery of the hammerhead disc 4. The hammerhead disc 4 is horizontally rotatable, and a crushing area is formed between the crushing component and the inner wall of the first cylinder 29.

[0035] Furthermore, such as Figure 2As shown, the crushing assembly 100 also includes a first liner 2. The first liner 2 is disposed on the inner wall of the first cylinder 29 and is correspondingly disposed with respect to the crushing component. The first liner 2 includes a plurality of first grinding columns, which are arranged circumferentially along the inner wall of the first cylinder 29, forming a crushing zone between the crushing component and the first liner 2. Coarse particles in the particulate material fall into the lower part of the first cylinder 29 under their own gravity and are quickly dispersed by the hammers 3 on the hammer disk 4, scattered around the hammer disk 4, and enter the crushing zone between the crushing component and the first liner 2. The hammer disk 4 rotates at high speed, generating a large number of air vortices. Under the dual action of air vortices and centrifugal force, the particulate material collides with each other and is sheared and ground by the hammers 3 on the hammer disk 4 and the first liner 2, achieving ultrafine crushing of the particulate material. The pulverized granular material is driven upward into the classification zone by the main airflow. Qualified micro powder particles are discharged through the first discharge port 10 by the classification impeller 7 and flow to the shaping component 200. Unqualified coarse powder particles are returned to the pulverizing area by the classification impeller 7 under the action of centrifugal force for further pulverization. The cycle continues until all particle sizes meet the requirements.

[0036] It is understood that the first cylinder 29 in this embodiment is a vertical structure. The first grinding column is parallel to the rotation axis of the hammer head disk 4, that is, it is set vertically.

[0037] In this embodiment, the minimum gap L1 between the hammerhead 3 and the first liner 2 and the diameter L2 of the hammerhead disc 4 satisfy the following ratio: 0.045 ≤ L1 / L2 ≤ 0.089. This setting ensures that the ratio in this embodiment is less than the ratio of the gap to the hammerhead disc 4 in typical crushing equipment. This improves the uniformity of particle material distribution within the first cylinder 29, thereby increasing crushing efficiency. Simultaneously, the reduced gap increases the probability of particle material collision, resulting in better crushing performance.

[0038] In this embodiment, the hammerhead 3 has multiple protrusions on its end face protruding from the outer periphery of the hammerhead disk 4, spaced apart. Specifically, the protrusions can be circular or elliptical. This arrangement increases the contact area between the hammerhead 3 and the particulate material, thereby increasing the crushing intensity.

[0039] Furthermore, such as Figure 2 As shown, the crushing assembly 100 also includes a feeding mechanism, which has a first feed inlet 1 connected to the first cylinder 29. In this embodiment, the feeding mechanism is a spiral feeding mechanism. Furthermore, the crushing assembly 100 also has a first discharge outlet 10, which is connected to the first cylinder 29 via a classifying impeller 7.

[0040] Furthermore, such as Figure 2As shown, the crushing assembly 100 also includes a first shaft sleeve 5, a first driving member 6, a second shaft sleeve 8, and a second driving member 9. The rotating shaft of the hammer disc 4 is mounted below the first cylinder 29 via the first shaft sleeve 5. The first driving member 6 is driven to rotate the hammer disc 4 via the rotating shaft. Correspondingly, the second driving member 9 is mounted above the first cylinder 29 via the second shaft sleeve 8. The second driving member 9 is driven to rotate the classifying impeller 7 via the classifying impeller 7.

[0041] In this embodiment, both the first driving component 6 and the second driving component 9 are motors.

[0042] In this embodiment, as Figure 3 As shown, the shaping assembly 200 also includes a second liner 13. The second liner 13 is disposed on the inner wall surface of the second cylinder 12 and is correspondingly disposed with respect to the shaping disk 16. The second liner 13 includes a plurality of second grinding columns, which are arranged circumferentially along the inner wall surface of the second cylinder 12. A shaping area is formed between the shaping disk 16 and the second liner 13.

[0043] Furthermore, such as Figure 3 As shown, the shaping assembly 200 also includes shaping balls 14. Multiple shaping balls 14 are movably distributed between the inner walls of the shaping disk 16 and the second cylinder 12. More specifically, the shaping balls 14 are movably distributed between the shaping disk 16 and the second liner 13. By setting the shaping balls 14, agglomerated granular materials can be broken up, improving shaping efficiency. Specifically, the shaping balls 14 can be rotated to a certain height along with the second liner 13, and then fall due to their own gravity. The kinetic energy generated by the falling shaping balls 14 can break up the material inside the second cylinder 12. At the same time, the granular material rubs against each other during its movement with the shaping balls 14, which can grind the granular material.

[0044] In this embodiment, the high-speed rotation of the second liner 13 and the shaping disk 16 drives the particulate material to flow in three dimensions. The impact force, compressive force, and shear force from the second liner 13, the shaping disk 16, the shaping ball 14, and the particulate material act continuously on the particulate material, achieving the effect of removing the sharp edges of the particulate material through friction.

[0045] It is understood that the second cylinder 12 in this embodiment is a horizontal structure, that is, the rotation axis of the shaping disc 16 is a horizontal axis. Correspondingly, the second grinding column is horizontally positioned.

[0046] It should be noted that the arrows in the attached diagram indicate the flow direction of the particulate material.

[0047] like Figure 1As shown, the granular material processing device also includes a liquid addition component 300, which is connected to the second cylinder 12 and is used to add a binder for bonding the granular material into the second cylinder 12. The addition of the binder causes the micro-powder particles to adsorb each other and form spheres during rotation, achieving both densification and spheroidization through granulation / composite effects. Existing traditional processes do not add binders but instead use a dozen or so 60, 50, and 30 mills connected in series for continuous crushing and shaping (60 and 50 mills for crushing, 30 mill for shaping), ultimately producing 50% tailings with low value. The granular material processing device of this application adds binder to the shaping component 200 through the liquid addition component 300, thereby granulating and spheroidizing the fine powder, achieving a complete harvest effect.

[0048] In this embodiment, the shaping ball 14 also serves to prevent the particulate material from agglomerating excessively due to the addition of the binder.

[0049] In this embodiment, water is used as the binder. Using water as the binder is cost-effective, and compared to other binders, it results in a lower load and lower power consumption for the shaping component 200, without altering the coating structure. It also avoids material agglomeration and large particle clustering caused by the excessively high adhesion index of other binders. Of course, the binder can also be other materials such as liquid asphalt or resin, and can be selected according to actual needs.

[0050] like Figure 4 As shown, the granular material processing apparatus also includes a heating element 18. At least a portion of the heating element 18 extends into the second cylinder 12 and is located between the shaping disc 16 and the inner wall of the second cylinder 12, for heating the granular material. Through this arrangement, heating during the shaping process intensifies the mutual adsorption force between the fine powder particles, resulting in a tighter bond. After a certain period of shaping, the heating element 18 is turned on. After a certain period of time, the fine powder particles are completely bonded together, and the moisture has evaporated completely.

[0051] It should be noted that when water is selected as the binder, the heating element 18 is installed. In order to prevent water from evaporating when the forming begins, the temperature is raised after a period of time. This makes the fine powder particles bond more tightly while the water evaporates. The final product does not require any other processing and can be used directly.

[0052] like Figures 3 to 5As shown, the liquid addition assembly 300 includes a spray pipe 27 and nozzles 28. The spray pipe 27 has a spray section extending into the second cylinder 12, located between the shaping disc 16 and the inner wall of the second cylinder 12 and parallel to the rotation axis of the shaping disc 16. More specifically, the spray section is located between the shaping disc 16 and the second liner 13. Multiple nozzles 28 are spaced apart within the spray section. This arrangement allows the binder to be more evenly added to the shaping area and sprayed onto the particulate material.

[0053] Furthermore, such as Figure 6 As shown, the liquid filling assembly 300 also includes a storage tank for storing the adhesive. A liquid inlet 19, a pressure gauge 20, and an air inlet 21 are respectively provided above the storage tank. The liquid inlet 19 is used to add adhesive to the storage tank, the pressure gauge 20 is used to measure the pressure of the storage tank, and the air inlet 21 is used to supply compressed air to the storage tank as a power source.

[0054] Furthermore, such as Figure 6 As shown, the dispensing assembly 300 also includes a weighing module 22 and a flow meter 23. The weighing module 22 is used to weigh the binder, and the flow meter 23 is installed on the outlet pipe of the storage tank to measure the flow rate of the binder. Through this setup, precise dispensing of the binder can be achieved, thereby accurately controlling the proportion and rate of the binder and ensuring the performance of the final product.

[0055] Furthermore, such as Figure 6 As shown, the liquid addition assembly 300 also includes a control valve 26, which is installed on the outlet pipe of the storage tank and is used to control the opening and closing of the spray pipe 27 by its own opening and closing. In this embodiment, the control valve 26 can be a pneumatic valve or a solenoid valve.

[0056] Furthermore, such as Figure 6 As shown, the liquid addition assembly 300 also includes a purge port 24 and a liquid outlet 25. The liquid outlet 25 is located at the end of the storage tank's outlet pipe and is connected to the spray pipe 27. The purge port 24 is located on the storage tank's outlet pipe and is connected to an external air source for purging the storage tank's outlet pipe, blowing any residual adhesive back into the tank.

[0057] Understandably, when there is no tail material generated during full recovery, the performance of the final product may decrease. This application, by reasonably setting the second liner 13, shaping disc 16, shaping ball 14, heating element 18 and spray pipe 27 of the shaping component 200, has the functions of shaping, heating and fusion coating. A binder is added during ball milling shaping. By adjusting the proportion and parameters, the product prepared by the particle material processing device of this application has no significant difference in performance from the product produced by the existing process.

[0058] The technical solution of this embodiment can flexibly adjust the type and proportion of the binder and the shaping parameters of the shaping component 200 to control the index of the particulate material, and the index is highly adjustable.

[0059] Below are a set of examples and comparative examples of spherical graphite processed by the particulate material processing apparatus of this application.

[0060] Example 1

[0061] Using the particulate material processing apparatus of this application, the material is shaped and prepared through the above processing steps. The material discharged from the crushing component 100 to the shaping component 200 has a D50 of 7-25 μm. Water is added at the inlet 19, with a graphite to water mass ratio of 5:1. The final prepared spherical graphite has a D50 of 10-25 μm, a yield close to 100%, and a tap density of 0.9 g / cm³. 3 The specific data is shown in Tables 1 and 2 below.

[0068] As can be seen from Tables 1 and 2 above, the electrochemical properties of spherical graphite prepared by the particulate material processing device of this application are basically consistent with those of traditional processes.

[0069] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By setting the particulate material processing device to include a crushing component 100 and a shaping component 200, the crushing component 100 includes a first cylinder 29, a crushing element, and a classifying impeller 7. The crushing element is rotatably disposed in the lower part of the first cylinder 29 for crushing the particulate material. The classifying impeller 7 is disposed in the upper part of the first cylinder 29 for classifying the crushed particulate material. The shaping component 200 includes a second cylinder 12 and a shaping disc 16. The second cylinder 12 is connected to the first cylinder 29, and the shaping disc 16 is rotatably disposed in the second cylinder 12 for... The granular material after grading is shaped. Through the interconnected crushing component 100 and shaping component 200, the granular material is first circulated and crushed in the first cylinder 29 of the crushing component 100. Qualified fine powder is discharged to the shaping component 200 by the airflow through the grading impeller 7, while unqualified coarse powder is thrown back to the lower part of the first cylinder 29 by the grading impeller 7 under the action of centrifugal force to continue crushing, thereby achieving ultra-fine crushing of the granular material. The crushed granular material enters the shaping component 200 for shaping, and finally forms spherical small-diameter particles. This eliminates the discharge of tail material in the entire processing, greatly improves the yield of granular material, and increases production efficiency.
