Description

VERTICAL CONTINUOUS STIRRED BALL-MILLING DEVICE AND
OPERATION METHOD THEREOF
TECHNICAL FIELD
[01] The present disclosure belongs to the technical field of powder processing machinery equipment, and relates to a ball milling device, in particular to a vertical continuous stirred ball-milling device and an operation method thereof.
BACKGROUND ART
[02] A stirred ball mill is key equipment in the field of manufacturing electronic raw materials and nanometer materials, and is also a commonly used powder processing equipment widely used in biology, food, cosmetics, medicine, material, mining, metallurgy and other industries. The movement of the stirrer results in shear and collision between steel balls or ceramic balls and raw materials, and realize crushing and milling of materials. However, on the one hand, the existing stirred ball mill cannot perform continuous production; on the other hand, the material processing parameters are all empirical parameters, and the distribution of particle sizes of the products is wide, which affects the quality. The existing ball mill needs to suspend ball milling, open the cover and dump the materials, which cannot realize continuous production. Advanced powder products require a narrow particle size distribution, that is, good particle uniformity. However, in the existing ball milling process, the particle sizes of products are mainly controlled by milling time. For ore and other materials, the milling time required by large particles or hard particles in raw materials is often different from that required by small particles or soft particles. Only controlling milling time will lead to excessive milling of some particles, thereby forming a wide particle size distribution and resulting in poor particle uniformity. Moreover, the product quality is easily affected by fluctuations in raw material quality.
[03] The disclosure CN108371995B discloses an automatic uncapping and loading device, which can realize automatic production, but does not change the traditional intermittent processing mode and the product quality control mode. The disclosure
CN209680239U adds a discharge port at a lower part of the tank and provides a sieve plate in a middle part of the tank. In theory, fine particles can quickly pass through the sieve plate during continuous production, so as to avoid excessive milling. However, in practice, the sieve plate is located below the powder and the milling balls, which is easily blocked by the powder while being worn and cannot play a role in screening the powder. The disclosure CN2341714 uses a by-pass ventilation method, in which the dust is carried upwards by gas, and based on different specific surface areas of the coarse and fine powders, the large particles fall back by gravity so as to realize screening. However, by-pass ventilation can only be used as a screening means for discharged materials, and the gas cannot touch the materials in the middle and lower parts of the cylinder body, which cannot avoid excessive milling of soft particles or fine particles. To realize continuous production of high-quality powder with narrow particle size distribution, it is required to provide an innovative technical route.
SUMMARY
[04] In view of the problems that the existing vertical stirred ball-milling technology and device cannot realize continuous production, and some materials are excessively milled, resulting in high energy consumption, low processing efficiency and low product quality, the present disclosure provides a vertical stirred ball-milling technology and device, which utilizes gas to bring the milled powder meeting product requirements out of the ball milling cylinder in time, thus avoiding excessive milling, improving uniformity of product particle size, enhancing product value, and realizing continuous production in combination with a feeding system.
[05] In order to achieve the above objects, it is provided a vertical continuous stirred ball-milling device, including a cylinder body, a plurality of milling balls, a cylinder cover, a stirrer and a gas inlet and outlet control system. The cylinder body is vertically provided. The plurality of milling balls are provided in the cylinder body.
The cylinder cover covers a top opening of the cylinder body in a sealed manner. The stirrer extends into the cylinder body through the cylinder cover and is rotatable.
Materials placed in the cylinder body are milled by the milling balls under rotation of the stirrer. The gas inlet and outlet control system includes a gas inlet channel and a gas outlet. An end of the gas inlet channel is provided on a bottom surface of the cylinder body and communicated with an interior of the cylinder body, and an other end thereof is communicated with a pressurized gas tank or a gas pump outside the cylinder body. The gas outlet is provided in the cylinder cover. The gas inlet and outlet control system further includes a spherical cap-shaped cover plate, the spherical cap-shaped cover plate is provided in the cylinder body and covers a port of the gas inlet channel, and the spherical cap-shaped cover is connected with the bottom surface of the cylinder body through an elastic member. When a gas inlet pressure is greater than a pressure in the cylinder body, the spherical cap-shaped cover plate is pushed to open by the gas inlet pressure; and when the gas inlet pressure is less than the pressure in the cylinder body, the spherical cap-shaped cover plate is automatically closed by a restoring force of the elastic member. A feed inlet running through an interior and an exterior of the cylinder body is provided in the cylinder cover.
[06] Further, the gas outlet is provided with a screen.
[07] Further, the gas inlet channel and the gas outlet each are provided with a gas valve.
[08] Further, the feed inlet is provided with a feed valve.
[09] Further, the stirrer is connected with the cylinder cover through a gastight bearing.
[10] Further, the vertical continuous stirred ball-milling device further includes a motor which is provided above the stirrer, an output shaft of the motor is connected with the stirrer to drive the stirrer to rotate.
[11] Further, the cylinder cover and the cylinder body are fastened by bolts.
[12] Further, sealing structures are further provided between the cylinder cover and the cylinder body.
[13] Further, the screen is fixed at a port of the gas outlet on a bottom surface of the cylinder cover, and the screen is detachably replaced as desired.
[14] It is further provided an operation method of the vertical continuous stirred ball-milling device. The operation method includes following steps: placing step, configured for placing raw materials to be processed and a plurality of milling balls in the cylinder body in advance; driving step, configured for driving the stirrer to rotate so as to move the raw material and the milling balls and in turn mill the raw material; where gas enters the cylinder body through the gas inlet and outlet control system, milled powder is carried by the gas and taken out of the cylinder body through the gas outlet, and a portion of the raw material which is not milled fully remains in the cylinder body to be continuously milled. The raw material is replenished through a feed inlet to realize continuous production.
[15] The present disclosure has the following beneficial effects.
[16] 1. In the production process, on the one hand, the finished products are blown out of the cylinder body by the gas, and on the other hand, the raw material and even the milling balls can be replenished through the feed inlet on the cylinder cover, without opening the cylinder cover or suspending ball milling, which can realize the uninterrupted and continuous production, and is more economical, efficient and convenient than the existing intermittent and batch production methods, and further is conducive to ensuring stable product quality.
[7] 2. The milled powder is taken out of the cylinder body by the gas from the gas outlet in time to avoid excessive milling, which can realize a narrower particle size distribution of the powder products, has a better uniformity of the powder particles better, and improving the product quality while the energy is saved.
[18] 3. The gas passes through the material layer from bottom to top, which helps to stir the material. Furthermore, it is beneficial to bring out the fine powder at various positions and effectively avoid excessive milling.
[19] 4. The inner side of the gas inlet uses a spherical cap-shaped cover plate, and the gas does not escape from one point, but is ejected along the annular slit formed between the outer edge of the cover plate and the inner bottom plate of the cylinder body, so that the contact range between the gas and the material 1s wider, and the effect is better.
[20] 5. The spherical cap-shaped cover plate can only be opened when the gas inlet pressure is sufficient. Once the gas inlet pressure is insufficient, the gas inlet will be 5 automatically closed due to the elasticity to prevent the material from entering or even blocking the gas inlet channel.
[21] 6. The screen at the gas outlet is replaceable. Compared with the traditional method of controlling the particle size of the product by milling time according to experience, it is more convenient and accurate to control the fineness of the product by using the screen with different mesh sizes.
[22] 7. The screening process is that the powder carried by the gas impacts the screen from bottom to top, which can more effectively avoid the blockage of the screen holes and improve screening efficiency and material throughput, compared with the traditional screening method of placing the material above the screen.
[23] 8. By integrating the milling and screening processes in one cylinder, the intensification of the device is realized, the area occupied by the device is reduced, and the compact device is beneficial to the gas tightness control.
BRIEF DESCRIPTION OF THE DRAWINGS
[24] FIG. 1 is a schematic structural diagram of a vertical continuous stirred ball-milling device according to the present disclosure.
DETAILED DESCRIPTION OF THE EMBODIMENTS
[25] Hereinafter, specific embodiments of the present disclosure will be explained with reference to the accompanying drawings.
[26] As shown in FIG. 1, the present disclosure provides a vertical continuous stirred ball-milling device, which includes a cylinder body 1, a plurality of milling balls 2, a cylinder cover 3, a stirrer 4 and a gas inlet and outlet control system.
[27] The cylinder body 1 is vertically provided.
[28] The plurality of milling balls 2 are provided in the cylinder body 1.
[29] The cylinder cover 3 covers on a top opening of the cylinder body 1 in a sealed manner, and a closed space required for production is formed between the cylinder cover 3 and the cylinder body. Specifically, the cylinder cover 3 and the cylinder body 1 are fastened by bolts 31. Sealing structures 32 are further provided between the cylinder cover 3 and the cylinder body 1 to ensure gas tightness of the system.
[30] The stirrer 4 extends into the cylinder body 1 through the cylinder cover 3 and is rotatable. Materials placed in the cylinder body are milled by the milling balls under rotation of the stirrer. Specifically, the stirrer 4 includes a stirring rod and a plurality of blades. The device further includes a motor 6 which is provided above the stirrer 4, and an output shaft of the motor 6 is connected with the stirrer 4 to drive the stirrer 4 to rotate.
[31] The stirrer 4 is connected with the cylinder cover 3 through a gastight bearing 41 to ensure the gas tightness of the system during the rotation of the stirrer 4.
[32] The gas inlet and outlet control system controls the gas to enter and leave the cylinder body 1. The gas can be reactive gas as required. The gas outlet part of the gas inlet and outlet control system has a function of controlling discharging.
[33] The gas inlet and outlet control system includes a gas inlet channel 51 and a gas outlet 52. One end of the gas inlet channel 51 is provided on a bottom surface of the cylinder body | and communicated with an interior of the cylinder body 1, and the other end thereof is communicated with a pressurized gas tank or a gas pump outside the cylinder body 1. The gas outlet 52 is provided on the cylinder cover 3.
[34] Opening and closing of the spherical cap-shaped cover plate 53 is controlled according to a relative pressure between the gas inlet pressure and the gas pressure in the cylinder body 1. When the gas inlet pressure is greater than the pressure in the cylinder body 1, the spherical cap-shaped cover plate 53 is pushed to open by the gas inlet pressure. The gas enters the cylinder body 1 through a circular slit formed between an edge of the spherical cap-shaped cover plate 53 and a bottom of the cylinder body 1, and passes through the material layer from bottom to top, so as to form a protective atmosphere in the cylinder body 1 or react with the material. When the gas inlet pressure is less than the pressure in the cylinder body 1, the spherical cap-shaped cover plate 53 is automatically closed by a restoring force of the elastic member, which prevents the material from entering the gas inlet channel 51 and prevents the gas inlet channel 51 from being blocked.
[35] The gas inlet channel 51 and the gas outlet 52 are both provided with gas valves 54. Closing the gas valve on the gas inlet channel 51 can reduce the gas inlet pressure, and closing the gas valve on the gas outlet 52 can cause the gas pressure in the cylinder body 1 to rise.
[36] A feed inlet 7 running through an interior and an exterior of the cylinder body 1 is provided in the cylinder cover 3. The feed inlet 7 is provided with a feed valve 71.
[37] Further in some embodiments, the gas outlet 52 is provided with a screen 55.
Specifically, the screen 55 is fixed at a port of the gas outlet 52 located at the bottom surface of the cylinder cover 3. In the production process, the gas inlet pressure is intermittently increased, so that the gas flow carries the powder material to impact the screen. The powder which is milled and qualified to reach the target fineness is blown out via the gas outlet channel along with the gas through the screen. The powder particles that are too large and do not reach the target fineness cannot pass through the screen, but fall back due to gravity and are continuously milled. The screen is replaceable, and a mesh size of the screen can be selected according to the target fineness of the product.
[38] The operation method of the vertical continuous stirred ball-milling device of the present disclosure includes the following steps:
[39] step 1, placing raw materials A to be processed and a plurality of milling balls 21n the cylinder body 1 in advance, which can be directly put into the cylinder body 1 by opening the cylinder cover 3 or be added into the cylinder body 1 through the feed inlet 7; and
[40] step 2, driving the stirrer 4 to rotate in order to drive the raw materials A and the milling balls 2 to move so that the raw materials A are milled.
[41] Furthermore, the gas enters the cylinder body through the gas inlet and outlet control system, the milled powder is carried by the gas due to its lightweight and taken out of the cylinder body 1 through the gas outlet 52, and the material which has not been milled completely remains in the cylinder body to be milled further.
[42] In some embodiments, for the device provided with the screen 55 at the gas outlet 52, the powder can be screened by the screen 55 first and then taken out by the gas for separation. The milled powder meeting the milling requirements is carried by gas and is taken out of the cylinder body 1 through the gas outlet 52. The materials that has not reached the particle size requirement (i.e., has not been completely milled) is blocked by the screen 55 and falls back into the cylinder body to be milled further, thus realizing discharging and separation of the powder products more accurately.
[43] The material is replenished through the feed inlet 7 to realize continuous production.
[44] After the milled powder carried by the gas is blown out of the cylinder body, the solid is the target product after air-solid separation. The gas can be reused after being pressurized. If it is reactive gas, a gas concentration sensor should be provided at the front end of the booster, so as to prevent the low concentration of the reactive gas trom affecting the product quality.
[45] In the production process, new materials and even milling balls can be replenished through the feed inlet and the feed valve on the cylinder cover, without opening the cover or suspending ball milling, which can realize an uninterrupted and continuous production, which is more economical, efficient and convenient than the existing intermittent and batch production methods, and further is conducive to ensuring stable product quality.
