A high-efficiency Raymond mill for titanium powder production

Abstract

This invention relates to the field of Raymond mill technology and discloses a high-efficiency Raymond mill for titanium powder production, comprising a main body, an air inlet pipe fixedly connected to the right side of the main body, a feed hopper fixedly connected to the back of the main body, and a grinding ring fixedly connected to the inner wall of the main body. When the rotating ring rotates, it collidees with the stuck material through multiple protrusions on its top. The broken material, after the collision, is then further ground and pulverized by the rotation of the rotating ring and the grinding ring as it falls. This reduces the slippage of lumpy material between the grinding roller and the grinding ring caused by the roller's rotation when it enters the space between the grinding roller and the grinding ring and is squeezed by the roller. This improves the stability of the material during grinding, and enhances the grinding efficiency and quality.

Description

Technical Field

[0001] This invention relates to the field of Raymond mill technology, specifically to a high-efficiency Raymond mill for titanium powder production. Background Technology

[0002] The high-efficiency Raymond mill for titanium powder production is a specialized powder processing equipment that optimizes the structure and upgrades the function of the traditional Raymond mill to address the characteristics of titanium metal, such as moderate hardness, high activity, and easy oxidation. The core of the equipment is the synergistic design of extrusion-shear grinding, airflow classification, and closed anti-oxidation system to achieve efficient, low-pollution, and controllable particle size processing from titanium blocks to titanium powder. It is widely used in titanium powder preparation in aerospace, powder metallurgy, 3D printing and other fields.

[0003] Titanium powder production requires grinding titanium blocks using a Raymond mill. During this process, internally suspended grinding rollers rotate rapidly around a central axis while simultaneously rotating on their own axis, squeezing the grinding ring under centrifugal force. This crushing action, combined with the squeezing and shearing action of the rollers and ring, pulverizes the material. The pulverized material is then carried by air to a classifier for grading. Materials meeting the standards are then sent to a dust collection system for dust removal. However, because the grinding rollers rotate while squeezing lumpy materials, when a large amount or very hard lumpy material enters between the rollers and the grinding ring, slippage can occur due to the rollers' rotation, affecting grinding efficiency and quality. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency Raymond mill for titanium powder production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a high-efficiency Raymond mill for titanium powder production, comprising a main body, an air inlet pipe fixedly connected to the right side of the main body, a feed hopper fixedly connected to the back of the main body, and a grinding ring fixedly connected to the inner wall of the main body, and further comprising:

[0007] The rotating mechanism is installed inside the main body to prevent the material from slipping during grinding.

[0008] An auxiliary mechanism is installed at the bottom of the rotating mechanism to prevent material from getting stuck on the side wall of the rotating mechanism when it is working and grinding materials.

[0009] Furthermore, a powder outlet pipe is fixedly connected to the top of the main body, and a classifier is rotatably connected inside the powder outlet pipe. The main body also includes:

[0010] The load-bearing components are installed inside the main body;

[0011] Pull-out component, which is installed on the side wall of the supporting component.

[0012] Furthermore, the rotating mechanism includes several connecting brackets disposed on the outer surface of the pulling component, and the rotating mechanism also includes:

[0013] A grinding assembly is installed at the bottom of several connecting brackets;

[0014] A sliding component is mounted on the side wall of the grinding component.

[0015] Furthermore, the auxiliary mechanism includes several L-plates disposed inside the grinding assembly, and the auxiliary mechanism also includes:

[0016] The active component is installed on the side wall of the L-plate.

[0017] Furthermore, the load-bearing component includes a rotating roller rotatably connected inside the main body, with the bottom of the rotating roller rotatably extending through to the bottom outer wall of the main body;

[0018] Several blades are fixedly connected to the outer surface of the rotating roller located inside the main body, and a perforated frame is bolted to the top of the rotating roller.

[0019] Furthermore, the pulling assembly includes four connecting rollers slidably connected to the side wall of the plum blossom frame, and a toothed shaft is fixedly connected to the bottom of the connecting rollers;

[0020] Several elastic plates are rotatably connected to the outer surface of the connecting roller, and the elastic plates are arranged in a circular array with the connecting roller as the center.

[0021] Furthermore, the top of the connecting frame is rotatably connected to the elastic plate;

[0022] The grinding assembly includes a grinding roller rotatably connected to the outer surface of the gear shaft. The outer surface of the grinding roller has several rectangular grooves, and short rods are fixedly connected inside the rectangular grooves.

[0023] The top of the grinding roller has several right-angled grooves, and a curved plate is slidably connected inside the right-angled grooves. The bottom outer wall of the grinding roller is connected to several rectangular grooves.

[0024] Furthermore, the sliding assembly includes right-angle rings rotatably connected to the bottom of the four connecting frames, and the right-angle rings slidably connected to the outer surface of the grinding roller;

[0025] The bottom of the right-angle ring is rotatably connected to several inclined plates, which are slidably connected to the outer surface of the short rod.

[0026] Furthermore, a rotating ring is provided at the bottom of several inclined plates, and the rotating ring is rotatably connected to the outer surface of the grinding roller;

[0027] Several L-shaped rods are fixedly connected to the bottom of the rotating ring, and several protrusions are fixedly connected to the top of the rotating ring.

[0028] Furthermore, the L-plate is slidably connected inside the rectangular groove;

[0029] The movable component includes a vertical plate fixedly connected to the side wall of the L-plate. Both the left and right sides of the vertical plate are fixedly connected to a return spring, and the end of the return spring away from the vertical plate is fixedly connected to the inner wall of the rectangular groove.

[0030] Several vertical plates are equipped with sliding discs at their bottom, which are slidably connected to the bottom of the grinding roller;

[0031] The side wall of the sliding disc has several notches, and a triangular plate is rotatably connected inside the notches;

[0032] The bottom of the sliding disk is in contact with several L-shaped rods.

[0033] The present invention has the following beneficial effects:

[0034] 1. In this invention, when the rotating ring rotates, the rotating ring will collide with the stuck material through multiple protrusions on the top. After the collision, the broken material will be ground and crushed again by the rotation of the rotating ring and the grinding ring as it falls. This can reduce the slippage of the material between the grinding roller and the grinding ring caused by the rotation of the grinding roller when the block material enters between the grinding roller and the grinding ring and is squeezed by the grinding roller. This can improve the stability of the material during grinding and improve the grinding efficiency and quality of the material.

[0035] 2. By maintaining the stable position of the connecting roller and the grinding roller, this invention can reduce the reaction force caused by the material obstruction when the grinding roller and multiple inclined plates compress the material, which would otherwise cause the grinding roller to shake and bounce within the frame. This ensures that the grinding roller can maintain sufficient extrusion force on the material to break it up, while also improving the grinding intensity of the grinding roller when grinding the material.

[0036] 3. In this invention, when the sliding disc slides upward, it drives the upward-rotating triangular plate to slide upward synchronously. At this time, the triangular plate pushes the blocky material on the side wall of the rotating inclined plate outward through the rectangular groove and the channel connected to the bottom. This reduces the situation where some blocky material gets stuck between the inclined plate and the rectangular groove when the inclined plate slides after being subjected to the reaction force of the material, which would cause material blockage and difficulty in resetting the inclined plate during subsequent grinding. This ensures that the grinding roller grinds the material stably while improving the crushing efficiency and continuity of the grinding and crushing path of the grinding roller on the blocky material in the grinding ring, and further improves the grinding efficiency.

[0037] 4. The present invention reduces the amount of material powder remaining in the rectangular groove and inclined plate during the grinding and crushing of materials by blowing gas into the rectangular groove. This ensures the smoothness of the inclined plate's reset and subsequent operation. It also reduces the accumulation of material powder in the rectangular groove or the jamming of the inclined plate during grinding. This further enhances the continuity of the inclined plate and right-angle ring when extruding materials, and improves the grinding efficiency when grinding blocky materials.

[0038] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1 - Figure 9 As shown, this invention is a high-efficiency Raymond mill for titanium powder production, comprising a main body 1, an air inlet pipe fixedly connected to the right side of the main body 1, a feed hopper fixedly connected to the back of the main body 1, and a grinding ring fixedly connected to the inner wall of the main body 1, and further comprising:

[0053] Rotating mechanism 2. The rotating mechanism 2 is installed inside the main body 1 to prevent the material from slipping during grinding.

[0054] Auxiliary mechanism 3 is installed at the bottom of rotating mechanism 2 to prevent material from getting stuck on the side wall of rotating mechanism 2 when rotating mechanism 2 is working and grinding material.

[0055] A powder outlet pipe 101 is fixedly connected to the top of the main body 1, and a classifier 102 is rotatably connected inside the powder outlet pipe 101. The main body 1 also includes:

[0056] Support component 11 is installed inside the main body 1;

[0057] Pull-up component 12 is installed on the side wall of the support component 11.

[0058] The rotating mechanism 2 includes several connecting brackets 201 disposed on the outer surface of the pulling assembly 12, and the rotating mechanism 2 also includes:

[0059] Grinding assembly 21 is installed at the bottom of several connecting brackets 201;

[0060] Sliding component 22 is mounted on the side wall of grinding component 21.

[0061] The auxiliary mechanism 3 includes several L-plates 301 disposed inside the grinding assembly 21, and the auxiliary mechanism 3 also includes:

[0062] The active component 31 is installed on the side wall of the L plate 301.

[0063] The supporting component 11 includes a rotating roller 111 rotatably connected inside the main body 1, with the bottom of the rotating roller 111 rotatably extending through to the bottom outer wall of the main body 1;

[0064] Several scrapers 113 are fixedly connected to the outer surface of the rotating roller 111 located inside the main body 1, and a pergola 112 is bolted to the top of the rotating roller 111.

[0065] The pulling assembly 12 includes four connecting rollers 121 that are slidably connected to the side wall of the plum blossom frame 112, and a toothed shaft 122 is fixedly connected to the bottom of the connecting rollers 121;

[0066] A number of elastic plates 123 are rotatably connected to the outer surface of the connecting roller 121, and the elastic plates 123 are arranged in a circular array with the connecting roller 121 as the center.

[0067] The top of the connecting frame 201 is rotatably connected to the elastic plate 123;

[0068] The grinding assembly 21 includes a grinding roller 211 rotatably connected to the outer surface of the gear shaft 122. The outer surface of the grinding roller 211 is provided with a plurality of rectangular grooves 212, and a short rod is fixedly connected inside the rectangular grooves 212.

[0069] The top of the grinding roller 211 has several right-angle grooves 213, and a curved plate is slidably connected inside the right-angle grooves 213. The bottom outer wall of the grinding roller 211 is connected to several rectangular grooves 212. When the grinding roller 211 rotates at the bottom of the connecting roller 121, the grinding roller 211 will drive the right-angle ring 221 and the rotating ring 223 to rotate synchronously. When the grinding roller 211 squeezes the hard and large amount of material between the grinding roller 211 and the grinding ring, the multiple inclined plates 222 on the outside of the grinding roller 211 will contact the material first.

[0070] The sliding assembly 22 includes a right-angle ring 221 rotatably connected to the bottom of four connecting frames 201, and the right-angle ring 221 is slidably connected to the outer surface of the grinding roller 211;

[0071] Among them, the bottom of the right-angle ring 221 is rotatably connected to several inclined plates 222. The inclined plates 222 are slidably connected to the outer surface of the short rod. When the inclined plates 222 slide in the rectangular groove 212, the inclined plates 222 will push the vertical plate 311 through the L plate 301 and make the vertical plate 311 stuck in the tooth recess on the surface of the gear shaft 122. At this time, the vertical plate 311 can put the grinding roller 211 and the gear shaft 122 into a single unit.

[0072] A rotating ring 223 is provided at the bottom of several inclined plates 222, and the rotating ring 223 is rotatably connected to the outer surface of the grinding roller 211;

[0073] Several L-shaped rods 224 are fixedly connected to the bottom of the rotating ring 223, and several protrusions are fixedly connected to the top of the rotating ring 223. When the right-angle ring 221 slides downward, the right-angle ring 221 will push the other multiple inclined plates 222 to slide in the rectangular groove 212.

[0074] L-plate 301 is slidably connected to the inside of rectangular groove 212;

[0075] The active component 31 includes a vertical plate 311 fixedly connected to the side wall of the L plate 301. Both the left and right sides of the vertical plate 311 are fixedly connected to a return spring. The end of the return spring away from the vertical plate 311 is fixedly connected to the inner wall of the rectangular groove 212.

[0076] Several vertical plates 311 are provided with sliding disks 312 at their bottoms, and the sliding disks 312 are slidably connected to the bottom of the grinding rollers 211;

[0077] The side wall of the sliding disk 312 has several notches, and a triangular plate 313 is rotatably connected inside the notches;

[0078] The bottom of the sliding disk 312 is in contact with several L rods 224. When the L rods 224 rotate, they will press on several protrusions at the bottom of the sliding disk 312. At this time, when the protrusions at the bottom of the sliding disk 312 are pressed by the L rods 224, they will drive several triangular plates 313 to slide up and down repeatedly.

[0079] In use, first connect the air inlet pipe on the side wall of the main body 1 to the external fan equipment, and simultaneously connect the powder outlet pipe 101 to the external dust collection equipment. Also, connect the classifier 102 and the rotating roller 111 to the external motor via a belt. Then, start the external motor. When the motor is working, it will drive the connected rotating roller 111 and classifier 102 to rotate rapidly via the belt. Afterwards, the operator will transport the material to be ground into the main body 1 through the feed hopper on the back of the main body 1. At this time, the rapid rotation of the rotating roller 111 will drive the connecting roller 1 through the spider frame 112. While the connecting roller 121 and the grinding roller 211 revolve around the vertical axis, the grinding roller 211 rotates on its own axis. At this time, the connecting roller 121 and the grinding roller 211 will press the grinding roller 211 tightly against the grinding ring inside the main body 1 under the action of centrifugal force. At this time, the material will be crushed under the squeezing and shearing action of the grinding roller 211 and the grinding ring. At the same time, the airflow generated by the external fan will blow the fine powder to the top of the main body 1. At this time, the rotation of the classifier 102 will screen the fine powder. The powder that meets the fineness will pass through while the coarse particles will fall back for re-grinding. This cycle continues until the required fineness is achieved, thereby achieving the purpose of grinding titanium particle powder.

[0080] When the grinding roller 211 rotates at the bottom of the connecting roller 121, it drives the right-angle ring 221 and the rotating ring 223 to rotate synchronously. When the grinding roller 211 squeezes the hard and abundant material between the grinding roller 211 and the grinding ring, the multiple inclined plates 222 on the outside of the grinding roller 211 will first contact the material. Then, when the right-angle ring 221 squeezes the material between itself and the grinding ring, the right-angle ring 221 will slide into the rectangular groove 212 under the resistance of the material's reaction. When the inclined plates 222 slide in the rectangular groove 212, the inclined plates 222... 22 will push the vertical plate 311 through the L plate 301, causing the vertical plate 311 to lock into the tooth recess on the surface of the gear shaft 122. At this time, the vertical plate 311 can put the grinding roller 211 and the gear shaft 122 into a single unit. At this time, the grinding roller 211 will not rotate on the surface of the gear shaft 122. At the same time, when the inclined plate 222 slides in the rectangular groove 212, the rotation of the inclined plate 222 will drive the right angle ring 221 to slide downward. Since the multiple inclined plates 222 are inclined at the bottom of the right angle ring 221, when the right angle ring 221 slides downward, the right angle... Ring 221 will then push the remaining inclined plates 222 to slide within the rectangular groove 212. When the right-angle ring 221 slides downward, the blocky material will be confined between the right-angle ring 221 and the rotating ring 223. Then, when the connecting roller 121 drives the grinding roller 211 to revolve, the grinding roller 211 will drive the material to change the grinding process from extrusion-shearing to pure extrusion and sliding friction on the inner wall of the grinding ring. At the same time, when the grinding roller 211 revolves, the rotating ring 223 will rotate on the surface of the grinding roller 211 through contact with the material on the inner wall of the grinding ring. When 223 rotates, the rotating ring 223 will collide with the stuck material through multiple protrusions on the top. After the collision, the broken material will be ground and crushed again by the rotation of the rotating ring 223 and the grinding ring as it falls. This can reduce the slippage of the material between the grinding roller 211 and the grinding ring when the lumpy material enters between the grinding roller 211 and the grinding ring and is squeezed by the grinding roller 211. This can improve the stability of the material during grinding and improve the grinding efficiency and quality.

[0081] When the inclined plate 222 slides within the rectangular groove 212 and causes the right-angle ring 221 to slide downwards, the sliding of the right-angle ring 221 will cause the four connecting frames 201 to slide downwards. When the connecting frames 201 slide downwards, the top of the connecting frame 201 will exert a downward pulling force on the top of the elastic plate 123. When the top of the elastic plate 123 is subjected to the pulling force, the elastic plate 123 will undergo an outward convex bending deformation. When multiple elastic plates 123 deform on the surface of the connecting roller 121, the deformed elastic plates 123 will adhere to and block the connection with the bottom of the flower frame 112. The possible swaying of roller 121 within the pergola 112 ensures that the connecting roller 121 drives the grinding roller 211 to maintain a stable position. By maintaining the stability of the positions of the connecting roller 121 and the grinding roller 211, the reaction force caused by the material obstruction when the grinding roller 211 and the multiple inclined plates 222 compress the material can be reduced. This would prevent the grinding roller 211 from swaying within the pergola 112 and causing the grinding roller 211 to bounce back. This ensures that the grinding roller 211 can maintain sufficient compressive force on the material to break it up while improving the grinding intensity of the grinding roller 211 when grinding the material.

[0082] When the inclined plate 222 compresses the material and slides within the rectangular groove 212 under the reaction force of the material, the bottom of the inclined plate 222 will cross the channel connecting the rectangular groove 212 and the bottom. Simultaneously, when the rotating ring 223 rotates, it drives multiple L-bars 224 to rotate synchronously. As the L-bars 224 rotate, they compress several protrusions on the bottom of the sliding disc 312. At this time, the protrusions on the bottom of the sliding disc 312, when compressed by the L-bars 224, will cause multiple triangular plates 313 to slide up and down reciprocally. Simultaneously, when the air force generated by the blower drives the crushed material upwards, the flowing gas will push the triangular plates 313 upwards, causing them to generate an upward force. As the sliding disk 312 rotates and then slides upward, the sliding disk 312 will drive the upward rotating triangular plate 313 to slide upward synchronously. At this time, the triangular plate 313 will push the blocky material on the side wall of the rotating inclined plate 222 outward through the channel connecting the rectangular groove 212 and the bottom. This can reduce the situation where some blocky material gets stuck between the inclined plate 222 and the rectangular groove 212 when the inclined plate 222 slides after being subjected to the reaction of the material, which would cause material blockage and difficulty in resetting the inclined plate 222 during subsequent grinding. This ensures that the grinding roller 211 grinds the material stably while improving the crushing efficiency and continuity of the grinding roller 211 in the grinding ring for grinding and crushing the blocky material, and further improves the grinding efficiency.

[0083] When the inclined plate 222 is not subjected to excessively hard blocky material, the inclined plate 222 and L-plate 301 will reset. When the inclined plate 222 resets, it will push the curved plate upward. Then, when the airflow flows upward through the slot on the sliding plate 312, the airflow will pass over the rectangular slot 212 and continue to flow upward. When the gas flows upward, it will enter the right-angle slot 213. At this time, some of the airflow will be guided by the curvature of the curved plate to generate turbulent flow in the rectangular slot 212, and at the same time, it will also affect the rectangular slot 212. The internal blowing force generated by the gas reduces the amount of material powder remaining in the rectangular groove 212 and the inclined plate 222 when the grinding roller 211 grinds and crushes the material. This ensures the smoothness of the inclined plate 222's reset and subsequent operation. It also reduces the accumulation of material powder in the rectangular groove 212 or the jamming of the inclined plate 222 during grinding. This further enhances the continuity of the inclined plate 222 and the right-angle ring 221 when extruding the material, and improves the grinding efficiency when grinding blocky materials.
