Description

Technical Field

[0001] The present invention relates to the technical field of high pressure roller mills, and in particular to an adaptive automatic control device for high pressure roller mills. Background Art

[0002] High pressure roller mill is a kind of efficient crushing equipment, which is widely used in fine and ultra-fine crushing of ores, etc. It has the advantages of energy saving, high efficiency and low wear. High pressure roller mill uses two rollers rotating in opposite directions to implement quasi-static pressure crushing and layer crushing on the material. In addition, high pressure roller mill is widely used in mining, metallurgy, chemical industry, building materials, engineering construction and other fields.

[0003] In the prior art, the patent with publication number CN109174405A discloses a high-pressure roller mill for construction ore, which includes a frame; a roller mill chamber, which is arranged on the frame; a first high-pressure roller and a second high-pressure roller, which are arranged in the roller mill chamber; a hydraulic drive device, which is used to drive the first and second high-pressure rollers to approach each other to squeeze and crush the material; a material dispersing chamber, which is arranged on the side of the roller mill chamber; a discharging inclined cylinder, which is arranged at the bottom of the roller mill chamber and penetrates into the material dispersing chamber from the side of the material dispersing chamber; a dispersing device, which is arranged in the material dispersing chamber, and the outlet of the dispersing inclined cylinder is located above the dispersing device; and a recycling and crushing device, which is used to screen and re-crush the material with larger particles. In the present invention, the crushing, dispersing, screening, and recycling processing operations can all be directly performed in one device, thereby effectively shortening the time for transporting the material between the corresponding equipment in each link, and greatly improving the work efficiency.

[0004] When the above patent is crushing the material, the material needs to be directly put into the hopper. Since the position of the hopper is fixed, the material falls directly between the two grinding rollers, which easily leads to uneven distribution of the material on the grinding roller, excessive accumulation of material at a single position, and it is not convenient to control the feeding speed according to the amount of material remaining on the grinding roller. If the material accumulates too much, the running resistance of the grinding roller will increase and the service life of the grinding roller will be reduced. Therefore, an adaptive automatic control device of the high-pressure roller mill is needed to meet people's needs. Summary of the invention

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The adaptive automatic control device of the high pressure roller mill of the present invention can use a conveyor belt to send materials to the hopper when in use. During the process, the feeding motor and the driving motor can be turned on. Under the action of the feeding motor, the materials in the hopper can be sent to between the two grinding rollers for crushing. Under the action of the driving motor, the material distribution bin can be reciprocated in the positioning frame, so that the materials can be evenly spread between the two grinding rollers, so that the materials are evenly distributed, and the situation of excessive accumulation of materials at a single position is prevented, thereby ensuring the normal operation of the high pressure roller mill and improving the crushing effect of the grinding roller;

[0021] (2) The adaptive automatic control device of the high-pressure roller mill of the present invention, as the material between the two grinding rollers increases, the material will squeeze the distance measuring plate upward. When the distance measuring plate is squeezed and rises, the position sensor can sense the position change of the distance measuring plate and transmit a signal to the driver to control the feeding motor to reduce the speed and reduce the feeding speed. When the material on the two grinding rollers gradually decreases, the distance measuring plate will be pushed down under the action of the limit spring. When the distance measuring plate is reset after being lowered, the position sensor will sense it and use the driver to control the speed of the feeding motor to resume, thereby increasing the feeding speed. Therefore, the feeding speed can be controlled according to the amount of material remaining on the two grinding rollers, thereby avoiding excessive accumulation of material and increasing the running resistance of the grinding rollers;

[0022] (3) The adaptive automatic control device of the high pressure roller mill of the present invention can make the extrusion plate reciprocate and squeeze the distance measuring plate under the action of the driving motor, press the distance measuring plate toward the material between the two grinding rollers, press the material onto the grinding rollers, increase the contact effect and extrusion force between the material and the grinding rollers, make the material more easily form fine particles and micro cracks, and further improve the crushing effect;

[0023] (4) The adaptive automatic control device of the high-pressure roller mill of the present invention can drive the limit plate to move on the pulley during the reciprocating movement of the material distribution bin, and the pulley can roll with the movement of the limit plate, so that the material distribution bin can move more smoothly during the movement, thereby ensuring the operation effect of the material distribution bin.

[0036] Furthermore, the material laying structure includes a slider 202, which is mounted on the inner wall of the material distribution bin 201, and a reciprocating screw 203 is threadedly mounted on the slider 202. Two connecting shafts 204 are rotatably mounted on the slider 202, and a first turntable 205 is mounted on one end of the two connecting shafts 204 close to each other, and a second turntable 206 is mounted on both ends of the reciprocating screw 203. The first turntable 205 and the second turntable 206 located on the same side are mounted with the same eccentric shaft 207, and two feeding motors 208 are mounted on the inner wall of the positioning frame 200, and a rotating shaft 209 is mounted on the output end of the two feeding motors 208, and spiral pieces 210 are mounted on the two rotating shafts 209. Two material troughs 211 are provided on the inner wall of the positioning frame 200, and the two spiral pieces 210 are movably mounted in the two material troughs 211 respectively. A driving motor 218 is mounted on one side of the positioning frame 200, and the output end of the driving motor 218 is mounted on one end of a corresponding connecting shaft 204. A hopper 219 is installed on the bin 201, and the hopper 219 is connected to the material distribution bin 201. One end of the conveyor belt 103 is located above the hopper 219. The feeding motor 208 and the driving motor 218 can be turned on. The output end of the feeding motor 208 can drive the rotating shaft 209 to rotate. When the rotating shaft 209 rotates, it can drive the spiral piece 210 to rotate, and the material is transported to between the two grinding rollers 101. The high-pressure roller mill 100 is used to control the rotation of the grinding roller 101 and crush the material. During the process, the output end of the driving motor 218 can drive the connecting shaft 204 to rotate, so that the connecting shaft 204 drives the first turntable 205 to rotate. When the first turntable 205 rotates, it can drive the second turntable 206 to rotate, so that the second turntable 206 drives the reciprocating screw rod 203 to rotate. During the rotation, the reciprocating screw rod 203 can drive the material bin 201 to slide back and forth on the inner wall of the positioning frame 200. The continuously moving material bin 201 can evenly spread the material between the two material bins 201.

[0037] Furthermore, a reciprocating screw hole 212 is provided on the inner wall of the slider 202, and the reciprocating screw rod 203 is threadedly installed in the reciprocating screw hole 212. The reciprocating screw rod 203 is provided with a thread that matches the reciprocating screw hole 212. During the rotation process, the reciprocating screw rod 203 can drive the cloth bin 201 to slide back and forth on the inner wall of the positioning frame 200 by cooperating with the thread of the reciprocating screw hole 212.

[0038] Furthermore, limiting plates 213 are installed on both sides of the cloth bin 201, and limiting grooves 214 are provided on one side of the two limiting plates 213.

During the movement of the cloth bin 201, the limiting plates 213 on both sides can be driven to move, so that the movable limiting plates 213 can move on the pulleys 215 through the limiting grooves 214. During the process, the pulleys 215 will roll with the movement of the limiting plates 213, so that the movement of the cloth bin 201 can be smoother.

[0039] Furthermore, L-shaped frames 216 are installed on both sides of the positioning frame 200, and the inner walls of the two L-shaped frames 216 are provided with guide grooves 217. Two limit plates 213 are respectively slidably installed in the two guide grooves 217. The movable limit plates 213 will slide in the guide grooves 217 on the L-shaped frames 216, thereby limiting the moving direction of the fabric bin 201 and preventing it from being offset.

[0040] Example 2

[0041] like Figure 3-8 In order to facilitate the control of the feeding speed according to the amount of material between the two grinding rollers 101, a material unloading control structure is arranged on the L-shaped support plate 300, and the material unloading control structure includes a plurality of slide bars 301, and the slide bars 301 are slidably installed on the L-shaped support plate 300. A distance measuring plate 302 is installed at one end of the slide bar 301, and a plurality of leakage holes are opened on the distance measuring plate 302. The distance measuring plate 302 is located between the two grinding rollers 101. A position sensor 303 is installed on one side of the L-shaped support plate 300, and the position sensor 303 is located above the distance measuring plate 302. The position sensor 303 is electrically connected to a driver 304, and the driver 304 is installed on the material distribution bin 201. The driver 304 is electrically Connected to the feeding motor 208, one end of the limiting spring 305 is installed on one side of the distance measuring plate 302, and the other end of the limiting spring 305 is installed on one side of the L-shaped support plate 300. The limiting spring 305 is slidably sleeved on the slide bar 301. In the process of continuous material transportation, if the material between the two grinding rollers 101 becomes more and more, it will squeeze the distance measuring plate 302 upward. At the same time, the position sensor 303 on the L-shaped support plate 300 senses the position change of the distance measuring plate 302 and transmits a signal to the driver 304. The driver 304 controls the rotation speed of the feeding motor 208 so as to adjust the feeding speed according to the amount of material between the two grinding rollers 101. The remaining features are the same as those in Example 1.

[0042] Example 3

[0043] like Figure 3-7In order to make the material contact with the grinding roller 101 better and improve the crushing effect, an extrusion structure is arranged on the sliding plate 400, and the extrusion structure includes a plurality of sliding rods 401, which are slidably installed on the sliding plate 400, and the two ends of the sliding rod 401 are respectively installed with an extrusion plate 402 and a baffle 403, and the extrusion plate 402 is located above the ranging plate 302. A connecting seat 404 is installed on the sliding plate 400, and one end of a connecting rod 405 is rotatably installed on the connecting seat 404, and the other end of the connecting rod 405 is rotatably installed on the eccentric shaft 207. An auxiliary spring 406 is slidably sleeved on the sliding rod 401, and the two ends of the auxiliary spring 406 are respectively installed on the sliding plate 400 and On the side where the extrusion plates 402 are close to each other, the eccentric shaft 207 in circular motion can drive one end of the connecting rod 405 to move back and forth, so that the reciprocating connecting rod 405 rotates on the connecting seat 404 and drives the connecting seat 404 to move back and forth, and the moving connecting seat 404 can drive the sliding plate 400 to slide on the inner wall of the L-shaped support plate 300. When the sliding plate 400 descends, the extrusion plate 402 will be driven to descend through the cooperation of the sliding rod 401 and the auxiliary spring 406, so that the extrusion plate 402 is squeezed above the ranging plate 302, and the ranging plate 302 is pressed against the material between the two grinding rollers 101, which can press the material on the grinding roller 101 to improve the crushing effect. The remaining features are the same as those in Example 2.

[0044] The working principle is as follows: when in use, the conveyor belt 103 is used to feed the material into the hopper 219, and then the material enters the material distribution bin 201 through the hopper 219. At this time, the feeding motor 208 and the driving motor 218 can be turned on, and the output end of the feeding motor 208 can drive the rotating shaft 209 to rotate. When the rotating shaft 209 rotates, it can drive the spiral piece 210 to rotate, so that the rotating spiral piece 210 can convey the material through the material trough 211 to between the two grinding rollers 101. When the high-pressure roller mill 100 is used to control the rotation of the grinding roller 101 and crush the material, the output end of the driving motor 218 can drive the connecting shaft 204 to rotate during the process. The connecting shaft 204 drives the first rotating disk 205 to rotate. When the first rotating disk 205 rotates, it can drive the second rotating disk 206 to rotate through the connection with the eccentric shaft 207, so that the second rotating disk 206 drives the reciprocating screw rod 203 to rotate. During the rotation process, the reciprocating screw rod 203 can cooperate with the thread of the reciprocating screw hole 212 to drive the material distribution bin 201 to slide back and forth on the inner wall of the positioning frame 200. At the same time, the material distribution bin 201 will drive the hopper 219 to move back and forth. During the process, the hopper 219 will still be under the conveyor belt 103 to avoid affecting the transportation of materials. The continuously moving material distribution bin 201 can evenly spread the materials on the two material distribution bins 201, to avoid excessive accumulation of materials in a single position, wherein, during the movement of the material distribution bin 201, the limit plates 213 on both sides can be driven to move, so that the movable limit plates 213 can move on the pulley 215 through the limit grooves 214, and the pulley 215 can roll with the movement of the limit plates 213 during the process, so that the movement of the material distribution bin 201 can be smoother. In the process of continuous material transportation, if more and more materials are between the two grinding rollers 101, the distance measuring plate 302 will be squeezed upwards, and the squeezed distance measuring plate 302 will drive the slide bar 301 to slide on the L-shaped support plate 300, and at the same time The distance measuring plate 302 will squeeze the limit spring 305 to compress it. At the same time, the position sensor 303 on the L-shaped support plate 300 senses the position change of the distance measuring plate 302 and transmits a signal to the driver 304. The driver 304 controls the speed of the feeding motor 208 to reduce, so that the feeding speed is reduced. When the material continues to decrease, the compressed limit spring 305 will release and push the distance measuring plate 302 to move and reset. At the same time, the position sensor 303 senses the position change of the distance measuring plate 302 again and uses the driver 304 to control the speed of the feeding motor 208 to resume, so as to adjust the feeding speed according to the amount of material between the two grinding rollers 101.

[0045] During the continuous rotation of the first rotating disk 205 and the second rotating disk 206, the eccentric shaft 207 can be driven to move in a circular motion, and the eccentric shaft 207 in a circular motion can drive one end of the connecting rod 405 to move back and forth, and at the same time, the connecting rod 405 can rotate on the eccentric shaft 207, so that the reciprocating connecting rod 405 rotates on the connecting seat 404 and drives the connecting seat 404 to move back and forth, and the moving connecting seat 404 can drive the sliding plate 400 to slide on the inner wall of the L-shaped supporting plate 300, and when the sliding plate 400 descends, it will drive the extrusion through the cooperation of the sliding rod 401 and the auxiliary spring 406. The plate 402 descends, so that the extrusion plate 402 is squeezed on the distance measuring plate 302, and the distance measuring plate 302 is pressed toward the material between the two grinding rollers 101. When the extrusion plate 402 cannot continue to descend, the continuously descending sliding plate 400 will compress the auxiliary spring 406 and slide on the sliding rod 401. Under the compression of the auxiliary spring 406, the force of the extrusion plate 402 squeezing the distance measuring plate 302 can be increased, and the moving distance of the extrusion plate 402 can be adapted according to the position of the distance measuring plate 302, so that the material can be pressed on the grinding roller 101, thereby improving the crushing effect.

[0046] The examples described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should all fall within the protection scope of the present invention.
