Description

Technical Field

[0001] The present invention relates to the technical field of Raymond mills, and more specifically, to a Raymond powder grinding device. Background Art

[0002] A Raymond mill is a device for high-precision powder processing of more than 280 kinds of materials in industries such as minerals, chemicals, and construction. This machine adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of Raymond mills in the same industry. This device has higher efficiency, lower power consumption, smaller floor area, and smaller one-time investment than ball mills. Under the action of centrifugal force, the grinding rollers are tightly pressed on the grinding ring. Therefore, when the grinding rollers and the grinding ring are worn to a certain thickness, it does not affect the output and fineness of the finished product. The replacement cycle of the grinding rollers and the grinding ring is long, thus eliminating the shortcoming of the short replacement cycle of vulnerable parts of centrifugal crushers. Currently, this machine is widely used for grinding various materials, and some powder materials have fineness requirements, so they need to be ground into finer powder.

[0003] According to the search, a patent with the patent number CN104668045B discloses a Raymond mill, which includes a machine base. A cylinder is connected to the top surface of the machine base. A grinding ring is installed in the machine base. A main shaft extending into the cylinder is rotatably connected to the machine base. A plum blossom frame is connected to the main shaft. Multiple sets of grinding roller assemblies are hinged on the plum blossom frame. The grinding roller assembly includes a grinding roller shaft hinged on the plum blossom frame and a grinding roller installed on the grinding roller shaft. A classifier is installed on the top of the cylinder. The classification rotor of the classifier is located at the top of the inner cavity of the cylinder. In the longitudinal sectional view of the grinding ring, the wall contour line of its inner wall surface is an outwardly convex arc. In the longitudinal sectional view of the grinding roller, the side contour line of its outer side is an outwardly convex arc. The products produced by this machine have finer particle sizes and are suitable for the production of ultra-fine powder.

[0004] In view of the above related technologies, the Raymond mill in the current prior art is usually in the above state during use. Although it can achieve material grinding and quantitative feeding, it is difficult to ensure the accuracy of each quantitative feeding during feeding, which affects the effect of quantitative feeding. At the same time, some powder materials will agglomerate after being placed for a period of time. There will be voids inside the agglomerated materials. Feeding such powder materials will further affect the effect of quantitative feeding. If the feeding is too little, the material between the grinding rollers and the grinding ring is insufficient, and the grinding function cannot be fully exerted. The equipment runs idly or at low load, wasting energy and reducing the grinding efficiency at the same time. For this reason, a Raymond powder grinding device is proposed. Summary of the Invention

[0027] Turn on the first motor 228, and the first motor 228 will drive the long rod 226 to rotate. When the long rod 226 rotates, it will drive the two first cams 227 to rotate. The rotation of the two first cams 227 will reciprocally push the first ball 225. The first ball 225 will roll on the outer surface of the first cam 227. The fixed frame 224 will drive the screen 230 to vibrate reciprocally through the longitudinal rod 223. The screen 230 will screen out the lumps in the powder material. The screened powder material will enter the inside of the material collecting hopper 210. At this time, the long rod 226 will drive one of the dredging rods 291 through the third transmission belt 294. The meshing of the two linkage gears 292 makes the two dredging rods 291 rotate. The rotation of the two dredging rods 291 will prevent the material from clogging and generating gaps. After a certain amount of material is stored in the material collecting hopper 210, the staff turns on the second motor 254.

[0029] When the other conveying roller 251 rotates, it will drive the connecting rod 261 to rotate quickly through the second large driving roller 268, the second transmission belt 269 and the second small driving roller 267. The connecting rod 261 drives the driving disk 262 to reciprocally push the reciprocating plate 263 to slide reciprocally inside the chute through the connecting arm. At this time, the cleaning brush 264 and the scraping plate 265 reciprocally move to scrape the powder adhering to the conveyor belt 252. After scraping, the powder enters the inside of the Raymond mill main body 110 through the bottom of the feeding box 120, avoiding the adhesion of materials and affecting the accuracy of the feeding amount.

[0030] The implementation principle of the embodiment of the present invention is as follows: When in use, the staff puts the powder to be processed into the upper feeding box 120 and above the sieve 230. Then, the first motor 228 is turned on. The first motor 228 will drive the long rod 226 to rotate. When the long rod 226 rotates, it will drive the two first cams 227 to rotate. The rotation of the two first cams 227 will reciprocally push the first ball 225. The first ball 225 will roll on the outer surface of the first cam 227. The fixed frame 224 will drive the sieve 230 to vibrate reciprocally through the longitudinal rod 223. The sieve 230 will screen out the lumps in the powder. The screened powder will enter the inside of the material collecting hopper 210. At this time, the long rod 226 will drive one of the dredging rods 291 through the third transmission belt 294. The two dredging rods 291 will rotate due to the meshing of the two linkage gears 292. The rotation of the two dredging rods 291 will prevent the material from clogging and generating gaps. After a certain amount of material is stored in the material collecting hopper 210, the staff turns on the second motor 254. The second motor 254 will drive one of the conveying rollers 251 to rotate, causing the conveyor belt 252 and the other conveying roller 251 to roll. At the same time, the second motor 254 drives the movable rod 248 to rotate through the first small transmission roller 255, the first transmission belt 257 and the first large transmission roller 256. The movable rod 248 drives a plurality of second cams 249 to rotate. The plurality of second cams 249 will reciprocally push the second ball 2410, causing the movable plate 241 to reciprocate. The return spring 242 will assist the movable plate 241 to return to its original position. The movement of the movable plate 241 will drive the feeding chute 245 to reciprocate. When the feeding chute 245 moves out of the material collecting hopper 210, it will take out the powder to be ground from the material collecting hopper 210. The material falls onto the conveyor belt 252 for feeding operation, so as to ensure uniform feeding to the Raymond mill main body 110, ensure the same feeding amount in each time period, give full play to the grinding effect of the equipment, ensure the grinding efficiency. By opening the replacement door 270, the fixing bolts 246 can be disassembled, and the clamping plate 243 and the feeding plate 244 can be removed from the movable plate 241. After removal, the staff can replace the feeding plate 244 with a feeding chute 245 of different sizes, and then reinstall the fixing bolts 246 to achieve different feeding amounts to meet different requirements. When the other conveying roller 251 rotates, it will drive the connecting rod 261 to rotate quickly through the second large transmission roller 268, the second transmission belt 269 and the second small transmission roller 267. The connecting rod 261 drives the driving disk 262 to reciprocally push the reciprocating plate 263 to slide reciprocally in the chute through the connecting arm. At this time, the cleaning brush 264 and the scraping plate 265 reciprocate to scrape the powder attached to the conveyor belt 252. The scraped powder enters the inside of the Raymond mill main body 110 through the bottom of the upper feeding box 120, avoiding the attachment of materials and affecting the accuracy of the feeding amount.

[0031] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
