Description

Technical Field

[0001] This utility model relates to the field of talc processing technology, and in particular to a combined high-efficiency airflow mill for talc preparation. Background Technology

[0002] Talc powder is a white or off-white fine powder made from talc ore through mining and grinding processes. Its main component is hydrated magnesium silicate. It has good lubricity, fire resistance and high melting point. It is widely used in many industrial fields. Natural talc ore resources are limited. The preparation process can improve resource utilization by rationally beneficiating and processing ore, transforming low-grade talc ore into high-value-added products, reducing resource waste and extending the service life of talc ore resources.

[0003] The combined high-efficiency air jet mill for talc powder preparation is a specialized device for the fine processing of talc powder, aiming to achieve efficient powder preparation. This equipment typically uses compressed air and superheated steam as power sources. Driven by a high-speed airflow, it achieves continuous and automated production, significantly improving production efficiency and product quality. It can meet the high-quality talc powder needs of various industries. However, in existing combined high-efficiency air jet mills for talc powder preparation, talc particles frequently collide and rub against internal components. The wear-resistant layer on the surface of these components is gradually eroded, exposing the metal material directly and subjecting it to further wear, resulting in a significant decrease in performance. To ensure stable equipment operation and product quality, regular replacement is required, necessitating time-consuming replacement and debugging by professional personnel. This increases maintenance costs and downtime, negatively impacting production efficiency. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides: a combined high-efficiency airflow mill for talc powder preparation, including a support frame 1, a feed hopper 3 fixedly connected to the top right side of the support frame 1, a valve 4 fixedly connected to the bottom of the outer wall of the feed hopper 3, an airflow pulverizing mechanism 5 connected to the bottom of the outer wall of the valve 4, an exhaust port 24 connected to the bottom right side of the airflow pulverizing mechanism 5, a separation hopper 6 fixedly connected to the bottom of the outer wall of the airflow pulverizing mechanism 5, a connecting pipe 7 connected to the top of the outer wall of the airflow pulverizing mechanism 5, a collection hopper 8 connected to the other end of the connecting pipe 7, an observation window 9 opened on the left side of the outer wall of the collection hopper 8, a packaging hopper 10 fixedly connected to the bottom of the outer wall of the collection hopper 8, a filter screen 11 fixedly connected to the middle of the inner wall of the collection hopper 8, a cleaning mechanism 2 fixedly connected to the left side of the outer wall of the support frame 1, the cleaning mechanism 2 is used to filter internal dust and impurities, handles 16 fixedly connected to the front and rear sides of the outer wall of the separation hopper 6, and multiple support feet 17 fixedly connected to the bottom of the outer wall of the airflow pulverizing mechanism 5.

[0032] Specifically, support frame 1 ensures device stability, feed hopper 3 stores talc raw materials, and operators adjust the raw material flow and speed into the airflow pulverizing mechanism 5 via control valve 4. The raw materials are pulverized through collision and friction under the action of high-speed airflow. The airflow is typically generated by an air compressor, and exhaust port 24 discharges waste gas to maintain stable air pressure. The pulverized talc powder mixes with the airflow; larger particles fall into separation hopper 6, while finer particles enter collection hopper 8 through connecting pipe 7. Filter screen 11 separates the talc powder, and operators monitor the collection process through observation window 9. Once a certain amount of talc powder is collected, it falls into packaging hopper 10 for subsequent processing. For packaging and sales, the device efficiently completes the preparation of talc powder through the coordinated work of its various components. A cleaning mechanism 2 is fixedly connected to the left side of the outer wall of the support frame 1. The cleaning mechanism 2 is used to filter internal dust and impurities. Handles 16 are fixedly connected to both the front and rear sides of the outer wall of the separation barrel 6. The handles 16 are used to facilitate the operator to stabilize and move the separation barrel 6 during use. The bottom of the outer wall of the airflow pulverizing mechanism 5 is also equipped with multiple support feet 17. The function of these support feet 17 is to ensure that the entire pulverizing mechanism can be stably placed on the ground during operation, preventing it from moving or tipping over due to vibration or external force.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 2 includes a drain pipe 201, which is fixedly connected to the top left side of the collection bucket 8. One end of the drain pipe 201 is fixedly connected to a flange 202, and the other end of the flange 202 is fixedly connected to a suction mechanism 203. A support plate 204 is fixedly connected to the top of the outer wall of the suction mechanism 203, and an exhaust pipe 205 is fixedly connected to the top of the outer wall of the support plate 204. A motor 206 is fixedly connected to the left side of the outer wall of the suction mechanism 203, and a baffle 12 is fixedly connected to the right side of the outer wall of the motor 206. A screw 13 is threadedly connected to one side of the outer wall of the baffle 12. Fasteners 14 are rotatably connected around the outer wall of the packaging bucket 10, and multiple fasteners 14 are rotatably connected to the top of the outer wall of the multiple fasteners 14.

[0034] Specifically, the structure is mainly responsible for the airflow treatment within the collection bucket 8. The suction mechanism 203 generates suction to draw out the filtered airflow, further treats it, and then discharges it, ensuring smooth airflow and preventing dust pollution. The motor 206 serves as the power source for the suction system; upon startup, it drives the impeller to rotate at high speed, generating negative pressure and forming suction. The unblocking pipe 201 connects the collection bucket 8 and the suction mechanism 203, and the flange 202 ensures a tight seal and connection. The airflow gains kinetic energy and changes direction within the suction mechanism 203, and after treatment, it is discharged through the exhaust pipe 205, meeting environmental protection requirements and reducing pollution. The motor 206 drives the suction mechanism 203 to generate suction, drawing in airflow through the unblocking pipe 201, which is then discharged through the exhaust pipe 205 after treatment, effectively treating and discharging the airflow and ensuring the normal operation of the talc powder preparation process. A baffle 12 is fixedly connected to the right side of the outer wall of the motor 206, mainly serving as a protective and isolating element. The baffle 12 is used to prevent debris and dust from entering the motor 206 when the motor 206 is running at high speed. To ensure that the baffle 12 is securely installed on the motor 206, a threaded screw 13 is used to fix it on one side of the outer wall, making it easy to remove the baffle 12. Multiple rotating buckles 14 are rotatably connected around the outer wall of the packaging barrel 10. The buckles 14 can rotate flexibly, which greatly facilitates the use of the packaging barrel 10. At the top of the outer wall of the multiple buckles 14, a rotatable ring 15 is connected to each buckle. When it is necessary to seal the packaging barrel 10 or connect and fix it with other components, the operator rotates the buckle 14 to the appropriate position and then fastens the ring 15 to the corresponding part, thereby achieving a stable connection and seal of the packaging barrel 10, preventing talcum powder leakage, and ensuring the hygiene and safety of the entire processing process.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the airflow pulverizing mechanism 5 is fixedly connected with a fixing ring 18. The left side of the outer wall of the fixing ring 18 is threaded with a bolt 19. The bottom of the outer wall of the valve 4 is fixedly connected with a connecting plate 20. The four corners of the outer wall of the connecting plate 20 are threaded with bolts 21. The outer wall of the collection bucket 8 is fixedly connected with multiple fixing plates 22. The outer wall of the fixing plate 22 is provided with multiple fixing holes 23.

[0036] Specifically, in the combined high-efficiency airflow mill for talc powder preparation, the structure plays different roles in stabilization and connection. The fixing rings 18 around the outer wall of the airflow pulverizing mechanism 5 are used to enhance its overall structural stability. When fixed by threaded connection using bolts 19, the airflow pulverizing mechanism 5 is prevented from shaking and shifting under the action of high-speed airflow, ensuring the stable operation of the pulverizing process. The connecting plate 20 at the bottom of the valve 4 is threadedly connected by bolts 21 at the four corners, allowing the valve 4 to be installed at the feed inlet of the airflow pulverizing mechanism 5. This ensures that the valve 4 can accurately control the flow rate and speed of talc raw materials entering the airflow pulverizing mechanism 5, while preventing leakage at the connection. The multiple fixing plates 22 and the multiple fixing holes 23 around the outer wall of the collection bucket 8 can be used to connect and fix it to the support frame 1, ensuring that the position of the collection bucket 8 is fixed during the talc powder collection process, avoiding shaking and displacement due to airflow or other external forces, thereby ensuring the normal and orderly operation of the entire talc powder preparation process.

[0037] Working Principle: The support frame 1 supports the entire device, ensuring its stability. The feed hopper 3 stores the talc raw material to be processed. Operators can adjust the flow rate and speed of the talc raw material entering the airflow pulverizing mechanism 5 by controlling the valve 4 at the bottom of the feed hopper 3 according to production needs. When the valve 4 is open, the talc raw material flows from the feed hopper 3 into the airflow pulverizing mechanism 5 under its own gravity for pulverization. After entering the airflow pulverizing mechanism 5, the mechanism uses high-speed airflow to cause the raw material particles to collide and rub against each other, thereby achieving pulverization. The high-speed airflow is usually generated by an air compressor and delivered to the airflow pulverizing mechanism 5. During the pulverization process, the exhaust port 24 on the bottom right side of the airflow pulverizing mechanism 5 serves to discharge waste gas, maintaining stable air pressure inside the mechanism and ensuring the normal operation of the pulverization process. At the same time, the discharged waste gas will carry away some heat, preventing the heat generated during pulverization from accumulating inside the mechanism and affecting equipment performance and product quality. The talc powder pulverized by the airflow pulverizing mechanism 5 mixes with the airflow. Due to gravity, larger talc particles... The powder falls downwards into the separation tank 6, which can initially separate larger particles to prevent them from entering the subsequent collection system and reduce the burden on subsequent equipment. In the crushed talc powder, the fine particles that meet the fineness requirements will enter the collection tank 8 through the connecting pipe 7 with the airflow. The filter screen 11 in the middle of the inner wall of the collection tank 8 plays a key separation role, blocking talc powder particles and allowing airflow to pass through, thereby collecting the talc powder in the collection tank 8. The operator can observe the collection of talc powder in the collection tank 8 in real time through the observation window 9 on the left side of the outer wall of the collection tank 8, and determine whether to proceed with the next step, clean the filter screen 11 and replace the packaging tank 10. When a certain amount of talc powder is collected in the collection tank 8, this talc powder will fall into the packaging tank 10 at the bottom by its own gravity. The packaging tank 10 can temporarily store the talc powder and facilitate the subsequent packaging process, making the talc powder into finished products for sale or use. This combined high-efficiency airflow mill realizes the multi-integrated operation of talc raw materials through the coordinated work of various components, and completes the preparation process of talc powder.

[0038] The main structure is responsible for processing the airflow inside the collection bucket 8. The suction mechanism 203 generates suction to draw out the airflow filtered by the filter screen 11 from the collection bucket 8, further processing it before discharge. This ensures smooth airflow throughout the talc powder preparation process and prevents dust spillage and environmental pollution. The motor 206 is the power source for the entire suction system. When the motor 206 starts, its output shaft drives the impeller inside the suction mechanism 203 to rotate at high speed. The rotation of the impeller creates a negative pressure area inside the suction mechanism 203, generating strong suction. From the collection bucket 8 to the suction mechanism 203, the suction generated by the suction mechanism 203 is transmitted to the collection bucket 8 through the drain pipe 201. One end of the drain pipe 201 is fixedly connected to the top left side of the collection bucket 8, and the other end is connected to the suction mechanism 203 through a flange 202. The flange 202 serves as a seal and connection, ensuring no leakage of airflow during transport. Under the action of suction, the airflow inside the collection bucket 8, filtered by the filter screen... The airflow, after filtering out most of the talc particles, is drawn into the suction mechanism 203 through the unblocking pipe 201. The airflow within the suction mechanism 203 is processed as follows: the airflow entering the suction mechanism 203 gains kinetic energy under the action of the impeller, further accelerating and changing its direction. The suction mechanism 203 guides and pressurizes the airflow, ensuring it can smoothly enter the subsequent exhaust pipe 205. The support plate 204 on the top of the outer wall of the suction mechanism 203 supports and fixes the exhaust pipe 205. The airflow processed by the suction mechanism 203 is discharged into the external environment through the exhaust pipe 205, ensuring that the discharged gas meets environmental protection requirements and reducing environmental pollution. The motor 206 drives the suction mechanism 203 to generate suction, drawing the airflow from the collection bucket 8 through the unblocking pipe 201. After processing by the suction mechanism 203, the airflow is discharged through the exhaust pipe 205, achieving effective processing and discharge of the airflow in the collection bucket 8, ensuring the normal operation of the entire talc preparation process.
