Description

Technical Field

[0001] The present invention belongs to the technical field of coal blending, and particularly relates to a refined coal blending system. Background Art

[0002] As an important energy resource, coal is widely used in multiple fields such as power generation, metallurgy, and chemical industry. It is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, and the sum of carbon, hydrogen, and oxygen accounts for more than 95% of the organic matter. According to the characteristics of coal, it can be divided into multiple types such as lignite, bituminous coal, anthracite, and semi-anthracite. Different types of coal have differences in calorific value, volatile matter, ash content, etc. Therefore, in practical applications, precise coal blending is required according to different process requirements to meet specific combustion, gasification, or coking needs.

[0003] However, there are many problems in the existing refined coal blending devices in practical applications, which limit the improvement of coal blending quality and efficiency. First, the coal outlet pipe in the existing coal blending devices cannot flexibly adjust the coal output according to the coal blending requirements. Since different processes have different requirements for the amount and proportion of coal, the fixed coal output cannot meet the diverse coal blending needs, resulting in a low degree of coal blending precision and thus affecting the coal blending quality. Second, the existing coal blending devices cannot crush the coal blocks added to the storage bin. When the coal blocks are large, it is easy to cause blockage of the coal outlet pipe, affecting the continuity of coal blending. At the same time, the large coal blocks are difficult to be evenly mixed during the coal blending process, further reducing the coal blending precision. In addition, the storage bin in the existing coal blending devices does not have a stirring function. The coal material is prone to blockage in the storage bin, especially in the case of high humidity or a large amount of coal powder, and the coal material is not easy to feed, resulting in obstruction of the coal blending process. Finally, the existing coal blending devices do not have a cleaning function and cannot effectively clean the conveyor belt. During long-term use, the surface of the conveyor belt is easily attached with coal material, which not only affects the conveying efficiency, but also may cause coal material pollution and waste, increasing the equipment maintenance cost and operation risk.

Among them, an adjusting plate 22 is rotatably connected inside the coal outlet pipe 7, the adjusting plate 22 and the coal outlet pipe 7 are connected by a pin shaft, one end of a pin shaft on one side is fixedly connected with a worm gear 24, a feeding port 23 is formed between one end of the adjusting plate 22 and the coal outlet pipe 7, two front plates 21 are fixedly connected to the position corresponding to the worm gear 24 at the front end of the coal outlet pipe 7, a motor 1 25 is fixed to one end of one side front plate 21, a worm 26 is arranged at the output end of the motor 1 25, a bearing rotating seat is arranged between the end of the worm 26 away from the motor 1 25 and the front plate 21, and a lubricating component 27 is arranged at the position corresponding to the worm 26 on the upper side of the front end of the coal outlet pipe 7.

[0036] By adopting the above technical solutions, when the motor 1 25 is started to drive the worm 26 to rotate, the rotation of the worm 26 can drive the adjusting plate 22 to rotate in the coal outlet pipe 7 through the worm gear 24. Different sizes of feeding ports 23 are formed between the rotation of the adjusting plate 22 and the coal outlet pipe 7. The coal material in the storage bin 9 falls onto the conveyor belt 6 through the feeding port 23.

[0037] Further in the present invention, the lubricating component 27 includes a cross plate 271, an oil tank 272, an oil injection pipe 273, a folding pipe 274 and a rope body 275. Among them, a cross plate 271 is fixedly connected to the position corresponding to the worm 26 on the upper side of the front end of the coal outlet pipe 7, an oil tank 272 is fixedly connected to the upper end of the cross plate 271, an oil injection pipe 273 is arranged on one side of the upper end of the oil tank 272, a pipe cap is threadedly connected to the upper end of the oil injection pipe 273, a folding pipe 274 is arranged on one side of the upper end of the oil tank 272, a rope body 275 is clamped inside the folding pipe 274, and one end of the rope body 275 extends into the oil tank 272.

[0041] When this embodiment is in use, during fine coal blending, install the device at a suitable position, add different types of coal materials into the two storage bins 9 respectively. The coal materials in the two storage bins 9 fall onto the conveyor belt 6 through the coal discharge pipe 7 to complete the coal blending work. The conveyor belt 6 conveys the coal materials. Start the first motor 25 to drive the worm 26 to rotate. The rotation of the worm 26 can drive the adjusting plate 22 to rotate in the coal discharge pipe 7 through the worm gear 24. Different sizes of material discharge openings 23 are formed between the rotation of the adjusting plate 22 and the coal discharge pipe 7. The coal materials in the storage bin 9 fall onto the conveyor belt 6 through the material discharge openings 23. By setting the adjusting assembly 2, the coal discharge amount of the coal discharge pipe 7 can be adjusted according to the coal blending requirements, improving the accuracy of coal blending.

The coal material is guided by the material guiding seat 37 and enters between the first crushing roller 35 and the second crushing roller 36. The first crushing roller 35 and the second crushing roller 36 rotate towards each other to crush the larger coal pieces. The crushed coal material falls into the storage bin 9. By setting the crushing assembly 3, the coal material added to the storage bin 9 can be crushed, avoiding the blockage of the coal outlet pipe 7 caused by the larger coal pieces added to the storage bin 9, and at the same time preventing the larger coal pieces from affecting the accuracy of coal blending.

When the sealing plate 381 is opened, the support plate 385 can support the sealing plate 381. By setting the sealing assembly 38, the upper end of the feeding pipe 31 can be sealed, avoiding the coal material splashing out of the feeding pipe 31 when crushing the larger coal pieces.

[0047] When the present embodiment is used, coal is put into the feeding pipe 31, the motor 2 32 is turned on to drive the crushing roller 1 35 to rotate clockwise, the crushing roller 1 35 drives the crushing roller 2 36 to rotate counterclockwise through the gear 1 33 and the gear 2 34, and the coal is guided into between the crushing roller 1 35 and the crushing roller 2 36 through the guide seat 37. The crushing roller 1 35 and the crushing roller 2 36 rotate in opposite directions to crush larger pieces of coal, and the crushed coal falls into the storage bin 9. By setting the crushing assembly 3, the coal added to the storage bin 9 can be crushed to avoid the large pieces of coal added to the storage bin 9. When the coal is added to the discharge pipe 31, the sealing plate 381 is moved by the lever 384, and the rotating seat 383 at one end of the sealing plate 381 rotates on the folding plate 382. After the sealing plate 381 rotates to the discharge pipe 31, the upper end of the discharge pipe 31 can be sealed. After the sealing plate 381 is opened, the support plate 385 can support the sealing plate 381. The upper end of the discharge pipe 31 can be sealed by setting the sealing assembly 38 to prevent the coal from splashing out of the discharge pipe 31 when the larger coal block is broken;

[0061] The structures and working principles of the support 1, conveyor belt 6, coal discharge pipe 7, sealing cover 8 and storage bin 9 in the present invention have been disclosed in an environment-friendly coal blending device with Chinese patent application number 2018201980674. Its working principle is to separately add different types of coal materials into two storage bins 9. The coal materials in the two storage bins 9 fall onto the conveyor belt 6 through the coal discharge pipe 7 to complete the coal blending work, and the conveyor belt 6 conveys the coal materials.

[0062] Working principle and use process of the present invention: When fine coal blending is carried out, the device is installed at a suitable position, and different types of coal are added to the two storage bins 9 respectively. The coal in the two storage bins 9 falls onto the conveyor belt 6 through the coal outlet pipe 7 to complete the coal blending work. The conveyor belt 6 transports the coal, and the motor 25 is turned on to drive the worm 26 to rotate. The rotation of the worm 26 can drive the adjustment plate 22 to rotate in the coal outlet pipe 7 through the worm gear 24. The adjustment plate 22 rotates and forms a discharge port 23 of different sizes between the coal outlet pipe 7. The coal in the storage bin 9 falls onto the conveyor belt 6 through the discharge port 23. By setting the adjustment component 2, the coal output of the coal outlet pipe 7 can be adjusted according to the coal blending demand, thereby improving the accuracy of coal blending. By setting the lubrication component 27, the oil injection pipe 273 Lubricating oil is injected into the oil tank 272, and one end of the rope body 275 inside the folded tube 274 extends into the oil tank 272 to absorb the lubricating oil. The other end of the rope body 275 can drip the lubricating oil onto the worm 26, thereby achieving the lubrication effect between the worm 26 and the worm wheel 24. By setting the lubricating component 27, the worm 26 and the worm wheel 24 can be self-lubricated to improve the service life of the worm 26 and the worm wheel 24. The handles at both ends of the oil receiving box 276 are held to place the oil receiving box 276 on the side plate 277, and the strip plates 278 on both sides of the lower end of the oil receiving box 276 can enter the strip grooves 279 in the side plate 277 to achieve the effect of limiting and fixing the oil receiving box 276. The oil receiving box 276 can receive the lubricating oil dripping on the worm 26 and the worm wheel 24. To prevent the lubricating oil from dripping and polluting the processing environment, put the coal into the feeding pipe 31, turn on the motor 2 32 to drive the crushing roller 1 35 to rotate clockwise, and the crushing roller 1 35 drives the crushing roller 2 36 to rotate counterclockwise through the gear 1 33 and the gear 2 34. The coal is guided into between the crushing roller 1 35 and the crushing roller 2 36 through the guide seat 37. The crushing roller 1 35 and the crushing roller 2 36 rotate in opposite directions to crush larger pieces of coal. The crushed coal falls into the storage bin 9. By setting the crushing component 3, the coal added to the storage bin 9 can be crushed to avoid the coal outlet pipe 7 being blocked when the coal pieces added to the storage bin 9 are large. At the same time, the large coal pieces affect the accuracy of coal blending. By setting the sealing component 38, after the coal is added to the feeding pipe 31, The sealing plate 381 is moved by the lever 384, and the rotating seat 383 at one end of the sealing plate 381 rotates on the folding plate 382. After the sealing plate 381 rotates to the discharge pipe 31, the upper end of the discharge pipe 31 can be sealed. After the sealing plate 381 is opened, the supporting plate 385 can support the sealing plate 381. By setting the sealing component 38, the upper end of the discharge pipe 31 can be sealed to prevent the coal from splashing out of the discharge pipe 31 when the larger coal blocks are broken. When the batching work is performed, the motor 41 is turned on to drive the long rod 43 to rotate. The rotation of the long rod 43 drives the short rod 44 to rotate through the pulley 46 and the connecting belt 47. The rotation of the long rod 43 and the short rod 44 drives the rotation of the plurality of stirring rods 45 to stir the coal in the storage bin 9. The coal in the storage bin 9 can be stirred by setting the stirring component 4.To prevent the coal material from jamming in the storage bin 9 and being unable to discharge, by setting the sealing component 38, the operator holds the baffle 481 and inserts the insertion rods 484 at the lower ends of the fixing frames 482 on both sides of the upper end of the baffle 481 into the slots 486 of the fixing seat 483. At the same time, an arc-shaped protrusion 485 is provided at the lower end of the insertion rod 484 to facilitate the insertion of the insertion rod 484 into the slot 486. After the baffle 481 is installed, it can block the coal material falling from the coal discharge pipe 7 onto the conveyor belt 6, preventing the coal material from splashing out of the conveyor belt 6 when it falls onto the conveyor belt 6 and causing waste of coal material. At the same time, the baffle 481 is installed through the insertion rod 484 and the like, which is convenient for disassembling, assembling and cleaning the baffle 481. One end of the chip collecting box 51 is closely attached to one end inside the bracket 1, and the rear end of the chip collecting box 51 is closely attached to the positioning plate 52. Then, the fixing bolt 57 is screwed into the fixing hole 58 at one end of the chip collecting box 51 to limit and fix the chip collecting box 51. At the same time, the cleaning brush 55 and the scraping plate 56 on the upper end of the top plate 53 are closely attached to the lower end of the conveyor belt 6. When the conveyor belt 6 runs past the upper side of the top plate 53, the scraping plate 56 can scrape off the coal material attached to the conveyor belt 6, and the cleaning brush 55 can clean the surface of the conveyor belt 6. The coal material cleaned off falls into the chip collecting box 51 for storage. By setting the cleaning component 5, the surface of the conveyor belt 6 can be cleaned, preventing the surface of the conveyor belt 6 from being difficult to clean due to the attachment of coal material after long-term use, and improving the practicality of the device.
