Description

Technical Field

[0001] The present invention relates to the technical field of rare earth chloride extraction, and particularly to a monazite grinding device. Background Art

[0002] In the production process of rare earth chloride, monazite is an important raw material. When extracting, it is first necessary to reduce the particle size of monazite as much as possible to improve the reaction efficiency with lye; a ball mill is often used for grinding monazite.

[0003] A ball mill is a key device for crushing materials and then pulverizing them. A ball mill consists of a horizontal cylinder, hollow shafts for feeding and discharging, and grinding heads, etc. The cylinder is a long circular cylinder, and the cylinder is filled with grinding media. The cylinder is made of steel plates, and there are steel liners inside the cylinder, which are fixed to the cylinder through bolts and nuts. The grinding media are generally steel balls and are loaded into the cylinder according to different diameters and a certain proportion. The material is loaded into the cylinder through the hollow shaft at the feeding end of the ball mill. When the cylinder of the ball mill rotates, the grinding media are carried away by the cylinder due to the action of inertia, centrifugal force, and friction, and are attached to the cylinder liner. When they are carried to a certain height, they fall due to their own gravity. The falling grinding media act on the materials in the cylinder like projectiles, producing heavy impacts and grinding effects.

[0004] Since the steel balls keep colliding in the cylinder, the liner inside the cylinder needs to be replaced frequently. When replacing the liner, two people are required to cooperate. One person enters the cylinder to support the liner, and the other person fixes the liner outside the cylinder through nuts and bolts; the installation method of this liner is difficult for manual operation, and it is dangerous for workers to drill into the cylinder, with poor construction safety and low work efficiency. Summary of the Invention

The second forward rod drives the mounting plate to turn to the position where the lining plate needs to be installed, and then insert the insertion block into the slot. At the same time, press the pressing block. The pressing block compresses the spring through the connecting plate. When the insertion block is inserted into the slot, release the pressing block. At this time, the spring drives the connecting plate to move, and the connecting plate drives the second limiting block to slide out of the second connection groove and be inserted into the limiting slot, thereby realizing the limitation of the second forward rod.

[0019] By adopting the above technical solution, when replacing the lining plate, it is necessary to manually remove the end cover. Since the end cover is disc-shaped and heavy, it is very inconvenient and there are great safety hazards during manual disassembly. When transferring the end cover, the transfer motor is started. The transfer motor drives the transfer lead screw to rotate. The transfer lead screw drives the second slider to slide through the second lead screw nut. The second slider drives the transfer block to move under the end cover. Then, the adjusting assembly is adjusted. The adjusting assembly drives the U-shaped support block to rise until it abuts against the discharge pipe on the end cover.

Thus, when the end cover is moved away, the mounting plate rises simultaneously, realizing the mechanical linkage of the removal of the end cover and the rise of the mounting plate, simplifying the operation steps, and at the same time reducing the problems of excessive wiring and troublesome maintenance caused by installing the power source in the installation groove, and reducing the probability of failure during operation.

The pneumatic push rod presses the lining plate against the position in the fuselage where the lining plate needs to be installed through the rotating rod; Step 7: Manually thread the fixing nut onto the fixing bolt outside the fuselage to complete the installation of the lining plate.

When replacing the lining plate, it is necessary to manually remove the end cover. Since the end cover is disc-shaped and has a large weight, it is very inconvenient and there are great safety hazards during manual disassembly; when transferring the end cover, the transfer motor is started. The transfer motor drives the transfer lead screw to rotate. The transfer lead screw drives the second slider to slide through the second lead screw nut, and the second slider drives the transfer block to move below the end cover.

[0043] Since the lining plates 23 are installed on the entire inner circumferential side wall of the fuselage 21, it is necessary to adjust the orientation of the mounting plate 31. When adjusting the orientation of the mounting plate 31, manually rotate the second forward rod 351. The second forward rod 351 drives the mounting plate 31 to turn to the position where the lining plate 23 needs to be installed. Then insert the insertion block 353 into the slot 347, and at the same time press the pressing block 354. The pressing block 354 compresses the spring 357 through the connecting plate 355. When the insertion block 353 is inserted into the slot 347, release the pressing block 354. At this time, the spring 357 drives the connecting plate 355 to move, and the connecting plate 355 drives the second limiting block 356 to slide out of the second connecting groove 372 and be inserted into the limiting groove 348, thereby realizing the limitation of the second forward rod 351.

[0044] Reference Figure 8 The tightening mechanism includes two first connecting rods 361. The two first connecting rods 361 are both fixedly connected to the second forward rod 351 and are symmetrically arranged. The two first connecting rods 361 are both located at the end of the second forward rod 351 away from the first forward rod 345.

The ends of the two rotating rods 366 away from the first slider 365 are respectively rotatably connected to the two sliding rods 362.

[0045] When tightening the lining plate 23, the air cylinder push rod 363 is started. The air cylinder push rod 363 drives the first slider 365 to slide. The first slider 365 drives the two rotating rods 366 to rotate. The two rotating rods 366 respectively drive the two sliding rods 362 to slide. The two sliding rods 362 respectively drive the two mounting plates 31 to move. The two mounting plates 31 respectively drive the two lining plates 23 to be tightened against the inner side wall of the fuselage 21.

[0047] When clamping the lining plate 23, the clamping motor 322 is started. The clamping motor 322 drives the clamping gear 323 to rotate. The clamping gear 323 drives the two clamping racks 324 to slide. The two clamping racks 324 respectively drive the two clamping plates 321 to clamp the lining plate 23, thereby realizing the fixation of the lining plate 23 on the mounting plate 31 and reducing the probability of the lining plate 23 falling off.

[0048] The implementation principle of a monazite grinding device according to an embodiment of the present application is as follows: When replacing and installing the lining plate 23, first, the transfer motor 461 is started, which drives the insertion rod 42 and the U-shaped support block 44 to move below the end cover 22. Then, the worm 474 is manually rotated, which drives the insertion rod 42 to be inserted into the connecting ring 45 and makes the U-shaped support block 44 abut against the discharge pipe of the end cover 22. Then, the end cover 22 is manually removed from the fuselage 21. At this time, the transfer motor 461 rotates in the reverse direction and transports the end cover 22 away through the transfer block 41. At the same time, the transfer block 41 drives the transmission rack 53 to slide through the third connecting rod 51. The transmission rack 53 drives the transmission gear 52 to rotate. The transmission gear 52 drives the lifting lead screw 332 to rotate, and then drives the mounting plate 31 to rise through the first lifting block 331. Then, the lining plate 23 is manually placed on the mounting plate 31. At this time, the clamping motor 322 is started, and the clamping motor 322 drives the two clamping plates 321 to clamp the lining plate 23 through the clamping gear 323 and the clamping racks 324. Then, the forward movement motor 342 is started. The forward movement motor 342 drives the first forward movement rod 345 through the forward movement gear 343 and the forward movement rack 344. The first forward movement rod 345 transports the lining plate 23 to the position where the lining plate 23 needs to be installed on the fuselage 21 through the second forward movement rod 351. Then, the pneumatic push rod 363 is started. The pneumatic push rod 363 drives the first slider 365 to slide. The first slider 365 drives the two rotating rods 366 to rotate. The two rotating rods 366 respectively drive the two sliding rods 362 to slide. The two sliding rods 362 respectively drive the two mounting plates 31 to move, and the two mounting plates 31 respectively drive the two lining plates 23 to abut against the inner side wall of the fuselage 21.

[0049] The embodiment of the present application also discloses a method for installing a lining plate of a monazite grinding device.

[0050] A method for installing a lining plate of a monazite grinding device includes the following steps: Step 1: First, start the transfer motor 461. At this time, the transfer motor 461 drives the second slider 464 to slide under the end cover 22 through the transfer lead screw 462; Step 2: Manually rotate the worm 474. The worm 474 drives the worm wheel 473 to rotate, and then drives the insertion rod 42 to be inserted into the connection ring 45. At this time, manually remove the end cover 22 from the fuselage 21; Step 3: Start the transfer motor 461 again. The transfer motor 461 drives the end cover 22 to move away from the fuselage 21 through the second slider 464. While the second slider 464 slides, it drives the lifting assembly 33 to rise through the transmission mechanism 5; Step 4: Manually place the lining plate 23 on the mounting plate 31, and then start the clamping motor 322. The clamping motor 322 drives the clamping plate 321 to clamp the lining plate 23 on the mounting plate 31; Step 5: Start the forward movement motor 342. The forward movement motor 342 transports the lining plate 23 to the position in the fuselage 21 where the lining plate 23 needs to be installed through the first forward movement rod 345; Step 6: Start the pneumatic push rod 363. The pneumatic push rod 363 presses the lining plate 23 against the position in the fuselage 21 where the lining plate 23 needs to be installed through the rotating rod 366; Step 7: Manually thread the fixing nut 25 onto the fixing bolt 24 outside the fuselage 21 to complete the installation of the lining plate 23.
