Description

Technical Field

[0002] Ball mill is the key equipment for crushing materials after they are broken. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to grind various ores and other grindable materials by dry or wet method.

[0003] The patent document with application number 202110337462.2 discloses a ball mill, including a ball mill barrel, a power unit, a swing connecting frame, a collecting box, a scraping mechanism, a driving mechanism, a push-pull sliding mechanism, a hammering power mechanism and a hammering device, wherein the ball mill barrel is connected to the swing connecting frame, the swing connecting frame is connected to the collecting box, the scraping mechanism is connected to the collecting box, the driving mechanism is connected to the collecting box, both power units are connected to the collecting box, the push-pull sliding mechanism is connected to the power unit, the hammering power mechanism is connected to the power unit, and the hammering device is connected to the hammering power mechanism.

[0004] However, when a traditional ball mill discharges materials, the material may clump or adhere to the cylinder wall during the grinding process inside the ball mill, causing the discharge port to be blocked, and the adhesion between particles is large, making it difficult to achieve an ideal screening effect, which may cause the material to be unable to be discharged normally and the discharge efficiency to be low, thereby affecting the efficiency of the entire production line. In addition, during the operation of the ball mill, a large amount of invalid power consumption will be generated due to the rolling, collision and friction of the material in the cylinder. This power consumption will not only increase energy consumption, but also cause the equipment temperature to rise, affecting the stability and service life of the equipment. Utility Model Content

[0005] The utility model discloses a ball mill for alloy powder, which aims to solve the problems that when a traditional ball mill is discharging materials, the materials may agglomerate or adhere to the cylinder wall during the grinding process inside the ball mill, resulting in blockage of the discharge port, and the adhesion between particles is large, making it difficult to achieve an ideal screening effect, which may result in failure to discharge the materials normally and low discharging efficiency, thereby affecting the efficiency of the entire production line. In addition, during the operation of the ball mill, a large amount of invalid power consumption will be generated due to the rolling, collision and friction of the materials in the cylinder, which will not only increase the energy consumption, but also cause the temperature of the equipment to rise, affecting the stability and service life of the equipment. Technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A ball mill for alloy powder, comprising a ball mill body, first support frames are provided on both sides of the ball mill body, and second support frames are provided on one side of the two first support frames, and further comprising:

[0008] A feed pipe is provided between one of the second support frames and one of the first support frames, and a second motor is provided on one side of one of the second support frames, the output shaft of the second motor is fixedly connected to a feed screw, a second feed pipe and a feed hopper are provided on the circumferential outer wall of the feed pipe, a screening mechanism is provided on the circumferential inner wall of the second feed pipe near the top of the feed screw, a first feed pipe is provided on the top of the screening mechanism, and a discharge pipe and an air pump are provided on the circumferential outer wall of the first feed pipe.

[0009] When in use, first start the first motor, and the output shaft of the first motor drives the feed screw to rotate, and then the alloy to be processed and ground is successively conveyed to the inside of the ball mill body through the feed hopper and the feed screw, and then the ball mill body is driven to rotate by the output shaft of the first motor, so as to grind the alloy inside. During the grinding process, the vacuum pump and the screening mechanism can be used in conjunction, and the qualified alloy powder materials are successively output through the first feeding pipe, the second feeding pipe and the discharge pipe after wind screening. The alloy powder particles that do not meet the screening mechanism will fall into the feed pipe again due to their own gravity, and will be conveyed to the inside of the ball mill body by the feed screw for multiple grinding until they pass through the screening mechanism smoothly. The device can improve the discharge efficiency, reduce the loss to the equipment, and improve the grinding effect and discharge quality of the equipment.

[0010] In a preferred embodiment, the screening mechanism includes a mounting ring, a fixing ring and two pressure plates, the fixing ring is fixedly connected to the top of the second feed pipe, three first limit springs are arranged between the top outer wall of one of the pressure plates and the top inner wall of the fixing ring, a second limit spring is arranged between the top outer wall of one of the pressure plates and the top inner wall of the mounting ring, three first connecting rods and one second connecting rod are respectively arranged on the top outer walls of the two pressure plates, threads are provided on the circumferential outer walls of the first connecting rod and the second connecting rod near one end, one end of the first connecting rod and the second connecting rod are threadedly connected with threaded caps, a screen plate is arranged between the bottom outer wall of one of the pressure plates and the bottom inner wall of the fixing ring, and a connecting assembly is arranged on one side outer wall of the fixing ring.

[0011] When the sieve plate needs to be replaced or disassembled, first rotate the threaded cap on the top of the fixing ring in the opposite direction. At this time, the three limit springs lose the downward pressure and return to their original shape. Then rotate the connecting assembly in the opposite direction. Then the mounting ring and the sieve plate are disengaged from the fixing ring. Then turn the threaded cap on the top of the mounting ring. The operator pulls up the second connecting rod. At this time, the pressure plate is away from the upper surface of the sieve plate. The operator can replace sieve plates of various specifications and apertures according to actual production needs and place them in the mounting ring. The sieve plate can be replaced and installed by reversing the above operation. This arrangement can meet different production needs and improve the screening effect.

[0013] When it is necessary to fix the connection between the mounting ring and the fixing ring, first rotate the two connecting tubes. While the two connecting tubes rotate in place, the threaded rod connected inside the connecting tube moves straight left and right in the direction of the thread groove until one end of the threaded rod is completely inserted into the thread groove.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0023] The utility model discloses a ball mill for alloy powder, which is mainly used for discharging materials from a traditional ball mill. The material may agglomerate or adhere to the cylinder wall during the grinding process inside the ball mill, resulting in blockage of the discharge port, and the adhesion between particles is large, making it difficult to achieve an ideal screening effect, which may result in failure to discharge the material normally and low discharging efficiency, thereby affecting the efficiency of the entire production line. In addition, during the operation of the ball mill, a large amount of invalid power consumption will be generated due to the rolling, collision and friction of the material in the cylinder. Such power consumption will not only increase energy consumption, but also cause the temperature of the equipment to rise, affecting the stability and service life of the equipment.

[0024] Reference Figure 1 , Figure 2 and Figure 3 A ball mill for alloy powder includes a ball mill body 1, first support frames 2 are provided on both sides of the ball mill body 1, and second support frames 3 are provided on one side of the two first support frames 2, and further includes:

[0025] A feed pipe is provided between one of the second support frames 3 and one of the first support frames 2, and a second motor 15 is provided on one side of one of the second support frames 3, the output shaft of the second motor 15 is fixedly connected to a feed screw 14, a second feed pipe and a feed hopper 8 are provided on the circumferential outer wall of the feed pipe, a screening mechanism is provided on the circumferential inner wall of the second feed pipe near the top of the feed screw 14, a first feed pipe 9 is provided on the top of the screening mechanism, and a feed discharge pipe 10 and an air pump 13 are provided on the circumferential outer wall of the first feed pipe 9.

[0026] During the specific implementation process, a first motor 5 is provided on one side of one of the second support frames 3, and the output shaft of the first motor 5 is fixedly connected to one side of the ball mill body 1. When in use, the output shaft of the first motor 5 drives the ball mill body 1 to rotate, providing a power source for the rotation of the ball mill body 1.

[0027] Among them, a partition plate 17 is provided between the vacuum pump 13 and the discharge pipe 10, and the partition plate 17 is located on the circumferential inner wall of the first feeding pipe 9. The vacuum pump 13 is located obliquely above the partition plate 17. The discharge pipe 10 is inclined at an angle of 30-45 degrees to the horizontal plane. The vacuum pump 13 will generate negative pressure during operation. If there is no partition plate 17, the material in the discharge pipe 10 may flow back into the vacuum pump 13 due to the negative pressure, causing blockage or damage to the vacuum pump 13. The partition plate 17 can effectively prevent the material from entering the vacuum pump 13, and play a certain protective role on the vacuum pump 13. The inclined discharge pipe 10 is arranged to facilitate the rapid discharge of alloy powder particles during the transportation process of the first feeding pipe 9.

[0028] Specifically, when in use, the first motor 5 is started first, and the output shaft of the first motor 5 drives the feed screw 14 to rotate, and then the alloy to be processed and ground is successively conveyed to the inside of the ball mill body 1 through the feed hopper 8 and the feed screw 14, and then the ball mill body 1 is driven to rotate by the output shaft of the first motor 5, so as to grind the alloy inside. During the grinding process, the vacuum pump 13 and the screening mechanism can be used in conjunction with each other, and the qualified alloy powder materials are successively output through the first feeding pipe 9, the second feeding pipe and the discharge pipe 10 after being screened by wind. The alloy powder particles that do not meet the screening mechanism will fall into the feed pipe again due to their own gravity, and will be conveyed to the inside of the ball mill body 1 by the feed screw 14 for multiple grinding until they pass through the screening mechanism smoothly. The device can improve the discharge efficiency, reduce the loss of equipment, and improve the grinding effect and discharge quality of the equipment.

[0029] Reference Figure 1 and Figure 4 In a preferred embodiment, the screening mechanism includes a mounting ring 7, a fixing ring 16 and two pressure plates 19, the fixing ring 16 is fixedly connected to the top of the second feed pipe, three first limit springs 18 are arranged between the top outer wall of one of the pressure plates 19 and the top inner wall of the fixing ring 16, a second limit spring is arranged between the top outer wall of one of the pressure plates 19 and the top inner wall of the mounting ring 7, three first connecting rods and one second connecting rod are respectively arranged on the top outer walls of the two pressure plates 19, threads are provided on the circumferential outer walls of the first connecting rod and the second connecting rod near one end, one end of the first connecting rod and the second connecting rod are threadedly connected with a threaded cap, a sieve plate 20 is arranged between the bottom outer wall of one of the pressure plates 19 and the bottom inner wall of the fixing ring 16, and a connecting component is arranged on the outer wall of one side of the fixing ring 16.

[0030] The cross-sections of the mounting ring 7 and the fixing ring 16 are in an “I”-shaped structure, and the mounting ring 7 and the fixing ring 16 in the “I”-shaped structure facilitate the installation and positioning of the sieve plate 20 .

[0031] In a specific implementation process, the diameter of the inner wall of the circumference of the fixing ring 16 and the mounting ring 7 is equal to the diameter of the inner wall of the circumference of the first material conveying pipe 9 .

[0032] Specifically, when the sieve plate 20 needs to be replaced or disassembled, first rotate the threaded cap on the top of the fixing ring 16 in the opposite direction. At this time, the three limit springs 18 lose the downward pressure and return to their original shape. Then rotate the connecting assembly in the opposite direction. Then the mounting ring 7 and the sieve plate 20 are disengaged from the fixing ring 16. Then rotate the threaded cap on the top of the mounting ring 7. The operator pulls up the second connecting rod. At this time, the pressure plate 19 is away from the upper surface of the sieve plate 20. The operator can replace the sieve plates 20 of various specifications and apertures according to actual production needs and place them in the mounting ring 7. The above operation can be reversed to achieve the replacement and installation of the sieve plate 20. This arrangement can meet different production needs and improve the screening effect.

[0033] Reference Figure 1 and Figure 5 In a preferred embodiment, the connecting assembly includes eight connecting tubes 6, the top outer wall and the bottom inner wall of the mounting ring 7 are each provided with two limit openings, two adjacent connecting tubes 6 are connected to the inner walls of the limit openings through bearings, the circumferential inner walls of the two connecting tubes 6 are threadedly connected with a threaded rod 11, two threaded grooves 4 are provided at both ends of the fixing ring 16, and one end of the threaded rod 11 is threadedly connected to the inner wall of the threaded groove 4.

[0034] It should be noted that when the operator pushes the connecting cylinder 6, the two connecting cylinders 6 keep rotating in place (that is, their center positions do not move in space, but are allowed to rotate around the center). Since the two connecting cylinders 6 are connected to the threaded rod 11 through threads, this connection is usually designed to allow axial (linear) movement but limit relative rotation, so that the rotational motion of the threaded rod 11 is converted into linear motion along the thread.

[0035] Specifically, when it is necessary to fix the installation ring 7 and the fixing ring 16, first rotate the connecting tube 6. While the connecting tube 6 rotates in place, the threaded rod 11 inside the connecting tube 6 moves toward the thread groove 4 through the threaded connection until one end of the threaded rod 11 is completely inserted into the thread groove 4. If it is necessary to disassemble the installation ring 7 and the fixing ring 16, just perform the above steps in the reverse direction. This arrangement is simple and convenient, and the limiting and fixing of the installation ring 7 and the fixing ring 16 can be quickly achieved.

[0036] Reference Figure 1 and Figure 3 In a preferred embodiment, a fixed frame is provided near one end of the circumferential outer wall of the first feed pipe 9, and a fan 12 is provided on the outer wall of one side of the fixed frame. The air outlet of the fan 12 is located on one side of the partition plate 17, and the grid aperture of the partition plate 17 is smaller than the grid aperture of the sieve plate 20.

[0037] Specifically, when the vacuum pump 13 is not working, the fan 12 can be turned on, and the airflow generated by the fan 12 blows to the other side of the partition plate 17, thereby blowing away the alloy powder particles on one side of the partition plate 17 to prevent it from clogging or affecting the normal operation of the entire equipment.

[0038] Working principle: When in use, first start the first motor 5, and the output shaft of the first motor 5 drives the feed screw 14 to rotate, and then the alloy to be processed and ground is successively conveyed to the inside of the ball mill body 1 through the feed hopper 8 and the feed screw 14, and then the ball mill body 1 is driven to rotate by the output shaft of the first motor 5, so as to grind the alloy inside. During the grinding process, the vacuum pump 13 and the screening mechanism can be used in conjunction, and the qualified alloy powder materials are successively output through the first feed pipe 9, the second feed pipe and the discharge pipe 10 after being screened by wind. The alloy powder particles that do not meet the screening mechanism will fall into the feed pipe again due to their own gravity, and will be conveyed to the inside of the ball mill body 1 by the feed screw 14 for multiple grinding until they pass the screening mechanism smoothly.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
