Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and in particular to a processing equipment for ultrafine modified powders. Background Technology

[0002] Ultrafine modified powder processing equipment is a specialized device used to process powder materials to micron or even nanometer particle sizes and improve their physicochemical properties through surface modification technology. Its core function is to achieve ultrafine powdering and surface performance optimization through mechanical force, thermochemical action, or chemical coating. This equipment is applied in the polymer materials industry, coatings and inks industry, electronics and information industry, biopharmaceutical industry, environmental protection and catalysis industry, and new energy industry. Its function is to perform ultrafine powdering to achieve surface modification. It consists of a pulverizing unit, a modification unit, a classification unit, a heating and cooling system, a transmission and control system, and a collection and dust removal system.

[0003] In practical applications, due to the inherent physical property of powder materials to adhere to other powder particles and materials, and the frequent friction between powder particles and the inner wall of the container during processing, a large amount of static electricity is generated, making electrostatic adsorption unavoidable. As a result, a large amount of powder to be modified adheres to the inner wall of the modification unit, reducing material utilization and increasing material costs. At the same time, the adhered powder material increases the necessary operating time of the equipment, resulting in energy waste. Under current technological conditions, mechanical scraping and separate pretreatment and modification optimization are used to try to solve the above problems. However, in practical applications, the former generates additional noise due to the intense sliding friction between the scraper and the inner wall of the modification unit, and long-term frequent friction will cause micro-metal particles in the scraper and container to contaminate the powder material, reducing the yield. The latter requires multiple processing steps before starting the powder modification work, which consumes additional time, increases equipment and labor costs, and is not conducive to cost reduction and efficiency improvement.

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4The present invention provides an embodiment of a processing device for ultrafine modified powder, comprising a modification unit 1, wherein a cleaning mechanism 2 is installed inside the modification unit 1 and on the top front side, the function of the cleaning mechanism 2 is to clean the powder material adhering to the inner wall, and a circulation mechanism 3 is provided on the top rear side of the modification unit 1, the function of the circulation mechanism 3 is to recover the heat energy of the processing and generate electricity; the cleaning mechanism 2 includes a motor 201, which is installed on the top front side of the modification unit 1, and the output end of the motor 201 is fixedly connected to a drive gear 202. The driven gear 203 is meshed with the rear side of the driving gear 202, providing power to the cleaning mechanism 2. A central rotating shaft 204 is fixedly connected to the middle of the driven gear 203. Two connecting bases 205 are fixedly connected to the outer wall of the central rotating shaft 204, serving as the overall support mechanism for the cleaning mechanism 2 and extending through the modification unit 1. Dust removal components 206 are fixedly connected to the front and rear sides of the two connecting bases 205. The dust removal components 206 include two rotating grooves 2061, both of which are fixed to the front and rear sides of the connecting bases 205. Ball joints 2066 are slidably connected inside the two rotating grooves 2061, allowing the dust removal components 206 to rotate in multiple directions to adapt to different shapes of the modified unit. Modification unit 1 has two ball joints 2066 with telescopic rods 2062 fixedly connected to their outer walls. The outer walls of the two telescopic rods 2062 are provided with springs 2063, which can make the dust removal component 206 adaptively change its length and keep it close to the inner wall surface of modification unit 1. The ends of the two telescopic rods 2062 are fixedly connected to roller frames 2067. The middle of the two roller frames 2067 is rotatably connected to a rotating shaft 2064. The outer walls of the two rotating shafts 2064 are fixedly connected to dust removal rollers 2065, which are the main adhesive powder removal devices. The top of modification unit 1 is fixedly connected to a top cover 11. The front side of the top of the top cover 11 is fixedly connected to a motor bracket 10, which provides support and fixation for the motor 201.

[0033] Specifically, when the powder material is modified in modification unit 1, motor 201 is started. The output shaft of motor 201 drives the drive gear 202 to rotate. The drive gear 202 meshes with the driven gear 203, which in turn drives the central shaft 204 to rotate synchronously. The central shaft 204 drives the connecting base 205 to rotate, and the connecting base 205 drives the dust removal component 206 to move in a circular motion around the axis of the central shaft 204. The dust removal roller 2065 rolls on the inner wall of modification unit 1 under the rotation of the central shaft 204, using rolling friction to peel off and remove the adhered powder material. The two dust removal rollers 2065 are connected to the connecting base 205 through independent rotating grooves 2061 and ball joints 2066, respectively, and work independently without interference. The rotating groove 2061 is equipped with a spherical guide rail, and the ball joint 2066 can slide in multiple directions within the spherical guide rail, thereby allowing the dust removal roller 2065 to adjust its working angle according to the changes in the shape of the inner wall of modification unit 1. Spring 2063 is sleeved on the outside of telescopic rod 2062. When the dust removal component 206 contacts the inner wall of the modified unit 1, it is squeezed and undergoes elastic deformation. The resulting elastic force is transmitted to the dust removal roller 2065 through the telescopic rod 2062, enabling the dust removal component 206 to adapt to the diameter change of the inner wall of the modified unit 1 and provide the pressure required to peel off the powder. The inner wall of the modified unit 1 contacts the dust removal roller 2065, ensuring that the dust removal roller 2065 will not deflect irregularly due to the spherical characteristics of the rotating groove 2061, so that the dust removal roller 2065 can always stick tightly to the inner wall. This mechanism uses the rolling of the dust removal roller 2065 to clean the adhesive powder, changing the sliding friction of the traditional scraper to rolling friction, avoiding the generation of metal impurity particles on the dust removal component 206 and the inner wall of the modified unit 1 due to sliding friction, which would contaminate the powder to be processed. Moreover, through the multi-directional sliding of the ball joint 2066 and the elastic adjustment of the spring 2063, the working posture can be adjusted to a certain extent according to the shape of the modified unit 1.

[0034] Reference Figure 2 and Figure 5The circulation mechanism 3 includes a connecting pipe 301, which is located at the top rear side of the modification unit 1. Multiple guide plates 305 are fixedly connected to the inner wall of the connecting pipe 301. A filter screen 302 is fixedly connected to the rear end of the connecting pipe 301, and a spiral air passage 303 is fixedly connected to the rear side of the filter screen 302. The rear end of the connecting pipe 301 is connected to the front end of the spiral air passage 303 through the filter screen 302. The airflow is continuously accelerated in this pipeline system, thereby providing power to the generator 3045. A power generation component 304 is located at the rear side of the spiral air passage 303. The power generation component 304 includes rotating blades 3041, which are positioned... On the rear side of the spiral air passage 303, the outer wall of the rotating blade 3041 is fixedly connected to the driving gear 3042. The front side of the driving gear 3042 is meshed with the driven gear 3044. Through the linkage of the blade and the gear set, the mechanical energy generated by the rotating blade 3041 is transmitted to the generator rotor. The middle part of the driven gear 3044 is fixedly connected to the rotor connecting shaft 3043. The bottom end of the rotor connecting shaft 3043 is fixedly connected to the generator 3045, which can be guided to the outside and output power. The top of the outer wall of the modified unit 1 is fixedly connected to the fixing ring 9. The rear side of the fixing ring 9 is fixedly connected to the generator bracket 8 for stabilizing the generator 3045.

[0035] Specifically, the hot air generated during processing enters the connecting pipe 301 through the air outlet 4. The connecting pipe 301 serves as a transmission channel, guiding the airflow to the power generation component 304. A guide plate 305 is installed inside the connecting pipe 301; its special blade-like structure forces the airflow to begin a spiral forward motion within the connecting pipe 301, increasing the airflow speed by changing the airflow direction. A filter screen 302, installed in the middle of the connecting pipe 301, has a mesh-like structure and is used to intercept impurities mixed in with the hot airflow, preventing them from entering the power generation component 304 and affecting its operation. A spiral air passage 303 is located at the connection between the connecting pipe 301 and the power generation component 304, and it has… With a spirally tapering shape, as the diameter of the air passage gradually decreases, the airflow speed is further accelerated due to space compression when passing through. After the accelerated hot airflow enters the power generation component 304, it blows the rotating blade 3041. The rotating blade 3041 is fixedly connected to the drive shaft 3044. The rotating blade 3041 begins to rotate under force and drives the driven gear 2 3044 to rotate synchronously. The driven gear 2 3044 is connected to the rotor connecting shaft 3043 of the driven gear 2 through gear meshing, and transmits the rotational power to the rotor connecting shaft 3043. The rotor connecting shaft 3043 is connected to the rotor of the generator 2 3045, and its rotation generates electrical energy.

[0036] Reference Figure 1 and Figure 2The top rear side of the top cover 11 is connected to the air outlet 4, through which the heating airflow moves and flows. The top right side of the top cover 11 is connected to the feed inlet 7, through which the powder material to be processed is poured in. The bottom of the modification unit 1 is fixedly connected to the support frame 5, which supports the whole equipment. The top of the generator bracket 8 is fixedly connected to the protective shell 6, so that the rotation of the rotating blade 3041 is not affected by other external factors.

[0037] Specifically, an air outlet 4 is provided on the rear side of the top of the top cover 11, providing a flow path for the hot air generated during processing, allowing the hot air to be smoothly discharged from the interior of the modification unit 1 and enter the subsequent processing stage; the material is poured into the interior of the modification unit 1 through this outlet, and enters the modification unit 1 for processing under the action of gravity; the bottom of the modification unit 1 is fixedly connected to a support frame 5 by bolts, the support frame 5 includes multiple support legs, the bottom of the support legs are in contact with the ground, supporting and fixing the modification unit 1 as a whole at a certain height, keeping the equipment stable and preventing the equipment from tilting or shaking during operation; the top of the generator bracket 8 is fixedly connected to a protective shell 6 by welding, the protective shell 6 is closed, completely enclosing the rotating blade 3041 and related transmission components, forming an independent working space, blocking the entry of external debris, preventing external objects from colliding or interfering with the rotating blade 3041, allowing the rotating blade 3041 to rotate in a stable environment, ensuring the normal operation of the power generation component 304.

[0038] Working principle: When the powder material is modified in modification unit 1, motor 201 is started. Motor 201 drives drive gear 202, which in turn drives driven gear 203. Driven gear 203 then drives central shaft 204, which in turn drives connecting base 205 and dust removal assembly 206 for cleaning. Dust removal roller 2065 rolls on the inner wall of modification unit 1 under the rotation of central shaft 204, acting as a peeling roller to remove the adhered powder material. The two dust removal rollers 2065 work independently without interfering with each other. The ball joint 2066 in the rotating groove 2061 can slide in multiple directions, allowing the dust removal roller 2065 to adjust its working angle according to the changes in the shape of the inner wall of modification unit 1. Spring 2063... When the powder component 206 comes into contact with the inner wall of the modified unit 1, it is squeezed and deformed, generating elasticity. This allows the powder removal component 206 to adapt to the diameter change of the inner wall of the modified unit 1 and provide peeling pressure. The contact between the modified unit 1 and the dust removal roller 2065 ensures that the dust removal roller 2065 will not deflect irregularly due to the spherical characteristics of the rotating groove 2061, and can always stick tightly to the inner wall. This mechanism uses the rolling of the dust removal roller 2065 to clean the adhesive powder, changing the sliding friction of the traditional scraper to rolling friction. This causes the powder removal component 206 and the inner wall of the modified unit 1 to generate metal impurity particles that contaminate the powder to be processed. Moreover, it can adjust its working posture to a certain extent according to the shape of the modified unit 1, solving the problem of micro-metal particles contaminating the powder material and reducing the yield.

[0039] The hot air generated during processing enters the connecting pipe 301 through the air outlet 4. The connecting pipe 301 guides the airflow into the power generation component 304. The guide plate 305 forces the airflow to begin a spiral forward motion in the connecting pipe 301, accelerating the airflow speed. The filter screen 302 is used to intercept impurities in the hot airflow. The spiral tapering shape of the spiral air passage 303 can further accelerate the airflow speed. The accelerated hot airflow blows the rotating blades 3041, causing them to begin rotating and driving the driven gear 3044. The driven gear 3044 drives the rotor connecting shaft 3043, and finally, the rotor connecting shaft 3043 drives the rotor to rotate in the generator 3045, generating electricity. The above mechanism can reuse the heat generated during the production process, reducing production costs and improving energy efficiency.
