Description

Technical Field

[0001] The present invention relates to the field of coal processing equipment, and more particularly to a pulverizing system. Background Art

[0002] A pulverized coal furnace is a boiler equipment that uses pulverized coal as fuel. It has the advantages of rapid and complete combustion, large capacity, high efficiency, adaptability to a wide range of coal types, and easy control and adjustment. The combustion characteristic of a pulverized coal furnace is that the fuel enters the combustion chamber together with the air and burns in a suspended state. The pulverized coal used in the pulverized coal furnace is processed by a pulverizing system, which is composed of a coal feeder, a coal mill, etc. The coal feeder is arranged between the raw coal hopper and the coal mill.

[0003] There are many types of existing coal feeders. According to their structural characteristics and working principles, there are two types: volumetric and gravity types. Among the volumetric coal feeders, disc coal feeders and scraper coal feeders are more widely used. The disc coal feeder uses the adjustment of the disc speed and the position of the inner casing to change the amount of coal fed on the disc, and adjusts the scraper angle to change the amount of scraped coal. It has the advantages of compact structure and good sealing. However, when encountering high-moisture coal, the coal blocks stick to each other, which easily causes blockage in the gap between the inner casing and the disc, resulting in a reduction in the coal feeding speed and even interruption of the coal feeding process, seriously affecting the normal operation of subsequent equipment. Moreover, coal with high humidity is easy to slip on the disc, making it impossible for the coal to rotate synchronously with the disc, affecting the coal feeding speed and causing unstable coal feeding speed. Therefore, it is urgent to design a pulverizing system. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] There are various types of existing coal feeders in the prior art. According to their structural characteristics and working principles, there are two types: volumetric and gravity types. Among the volumetric coal feeders, disc coal feeders and scraper coal feeders are more widely used. The disc coal feeder changes the amount of coal fed on the disc by adjusting the disc rotation speed and the position of the inner sleeve, and changes the amount of scraped coal by adjusting the scraper angle. It has the advantages of compact structure and good sealing. However, when encountering high-moisture coal, the coal blocks stick to each other, which easily causes blockage in the gap between the inner sleeve and the disc, resulting in a reduction in the coal feeding speed and even interruption of the coal feeding process, seriously affecting the normal operation of subsequent equipment. Moreover, coal with high humidity is easy to slip on the disc, making it impossible for the coal to rotate synchronously with the disc, affecting the coal feeding speed, and causing the problem of unstable coal feeding speed.

[0047] Working principle:

[0048] First, the distribution control box 100 controls the operation of the adjusting motor 211, and then the adjusting motor 211 rotates the inner bevel gear ring 207 through the vertical rotating shaft 210, the driving wheel 209, and the transmission belt 208, and then the inner bevel gear ring 207 rotates the adjusting screw 203 through the meshing action between it and the transmission bevel gear 206, and then the internal threaded tube 202 moves upward with the lifting inner sleeve 10 through the adjusting plate 201 under the action of the threaded cooperation between it and the adjusting screw 203, and then the gap between the lifting inner sleeve 10 and the feeding disc 16 becomes larger, and then the adjusting plate 201 moves upward with the feeding amount detection mechanism 3, and then the linkage line 309 relaxes, and then the displacement threaded rod 306 rotates under the action of the torsion of the reset spring 307, and then the displacement screw The threaded rod 306 rotates with the load-bearing wire wheel 308, and then the linkage wire 309 is wound around the outside of the load-bearing wire wheel 308. At the same time, the strain block 310 moves to the right with the contact spring bar 311 under the action of the threaded fit between it and the displacement threaded rod 306. Then the length of the resistor bar 305 connected to the circuit becomes shorter, and then the current passing through the contact spring bar 311 becomes larger. Then the distribution control box 100 determines the gap width between the lifting inner sleeve 10 and the feeding disc 16 according to the current value, and then the gap width between the lifting inner sleeve 10 and the feeding disc 16 meets the requirements. Then the distribution control box 100 controls the adjustment motor 211 to shut down, and then loosens the locking bolt 600, and then applies a rotational force to the arc rod 69, and then the arc rod 69 carries the air scraper 61 Flip it over, and then determine the angle of the air scraper 61 according to the scale line on the arc rod 69 until the angle of the air scraper 61 meets the requirements, and then tighten the locking bolt 600, and then the locking bolt 600 locks the arc rod 69, and then locks the air scraper 61, and then the scraper body 64 moves downward under the action of the elastic repulsive force of the compression spring 67 and its own gravity, and then the bottom surface of the scraper body 64 is pressed on the top surface of the feeding disc 16, and then the feeding motor 13 is controlled to run through the power distribution control box 100, and then the feeding motor 13 drives the feeding shaft 15 to rotate clockwise through the reducer 14, and then the feeding shaft 15 drives the feeding disc 16 to rotate clockwise, and then the feeding disc 16 drives the cleaning structure 8 and the anti-slip structure 1000 to rotate clockwise. The anti-skid wheel 1006 moves upwards through the anti-skid arm 1005, and then the anti-skid flat tube 1003 moves upwards. Then the top of the anti-skid flat tube 1003 moves out from the inside of the anti-skid groove 1001. At the same time, the anti-skid flat tube 1003 pulls the pulling spring 1004, causing the pulling spring 1004 to elastically stretch, and the elastic potential energy increases. Then, the anti-skid wheel 1006 is aligned with the recessed groove 93, and then the anti-skid flat tube 1003 is inserted into the recessed groove 93 through the anti-skid arm 1005 under the action of the elastic force of the pulling spring 1004. Then the anti-skid wheel 1006 contacts the bottom surface of the inner cavity of the recessed groove 93.At this time, the top surface of the anti-slip flat tube 1003 is flush with the top surface of the feeding disc 16, and then the scraper body 64 slides over the top surface of the anti-slip flat tube 1003, and then the scraper body 64 separates from the anti-slip flat tube 1003, and then the anti-slip wheel 1006 walks onto the surface of the climbing slope 94, and then the surface of the climbing slope 94 applies an upward lifting force to the anti-slip wheel 1006, and then the anti-slip wheel 1006 moves upward with the anti-slip flat tube 1003 through the anti-slip arm bar 1005, and then the top of the anti-slip flat tube 1003 moves out from the inside of the anti-slip groove 1001, and then raw coal is added from the feeding pipe 19, and then the raw coal passes through the feeding pipe 19, the lifting inner sleeve 10, and flows from the gap between the lifting inner sleeve 10 and the feeding disc 16 to the feeding. On the top surface of the disc 16, the anti-slip flat tube 1003 is buried by the raw coal, and then the anti-slip flat tube 1003 pushes the raw coal to rotate synchronously with the feeding disc 16 to prevent the raw coal from slipping on the top surface of the feeding disc 16, and then the raw coal on the feeding disc 16 is scraped into the expansion shell 41 by the scraper body 64 and passes through the drop hole 43, the collecting cone pipe 45, and the drop short pipe 46 to impact the receiving cone 58. Then, the receiving cone 58 applies pressure to the pressure sensor 55 through the moving column 57 under the impact of the raw coal, and then the pressure sensor 55 detects the impact force and sends the detected data to the distribution control box 100. The distribution control box 100 learns the coal feeding speed according to the impact force, and then the raw coal slides from the receiving cone 58 and passes through the flaring pipe 51, the feeding The pipe 52 enters the coal mill. When the gap between the lifting inner sleeve 10 and the feeding disc 16 is blocked, the coal feeding speed is reduced, so that the impact force on the pressure sensor 55 is reduced. Then the distribution control box 100 detects this situation and reminds people that the coal feeder is blocked. Then the pull ring is pulled, and then the pull ring pulls the traction rope 715. Then the traction rope 715 pulls the linkage slide 710 to move to the left. At the same time, the traction rope 715 pulls the displacement rope 714. Then the displacement rope 714 pulls the expansion slider 705 through the displacement plug 713. Then the expansion slider 705 performs a scissor-like bite action with the scissor-like bite structure 706. Then the scissor-like bite structure 706 lifts the lifting plate 707, and then the lifting plate 707 contacts the load-bearing wheel 85 and lifts it. , then the bearing wheel 85 moves upward with the cleaning bar 86 through the lifting bar 83, and then the top of the cleaning bar 86 extends from the top of the insertion hole 87, and then the feeding disc 16 rotates clockwise in the gap between the lifting inner sleeve 10 and the feeding disc 16 through the insertion hole 87, and then the cleaning bar 86 contacts the blockage in the gap between the lifting inner sleeve 10 and the feeding disc 16 and applies an outward thrust to it, and then the blockage breaks and slides through the gap between the lifting inner sleeve 10 and the feeding disc 16 to the top surface of the feeding disc 16, achieving the blockage, and then the pull ring is released, and then the slider 705 is opened and moves away from the center disc 703 under the action of the elastic force of the opening spring 704 and pulls the displacement rope 714 through the displacement insert 713,The scissor-type interlocking structure 706 then shortens, causing the lifting plate 707 to descend. The lifting bar 83, under the elastic force of the energy storage spring 84, moves downward with the load-bearing wheel 85 and the cleaning bar 86. The lifting bar 83 then contacts the end stopper 82. At this point, the top surface of the cleaning bar 86 is flush with the top surface of the feed disc 16. The displacement rope 714 then pulls the traction rope 715, which in turn pulls the linkage slide 710 until the linkage slide 710 contacts one of the positioning arm plates 701, completing the reset.
