Description

Technical Field

[0001] The invention relates to the technical field of material guide troughs, and in particular to an air kinetic energy dust suppression material guide trough. Background Art

[0002] The air kinetic dust suppression material guide chute is based on the principles of aerodynamics and fluid mechanics. It reduces the pressure of the airflow in the material guide chute by means of capacity expansion and pressure relief, so as to get rid of the problem of spatial dust pollution during material point operation in the conveying system.

[0003] The existing Chinese patent with announcement number CN210619639U discloses a dust suppression material guide trough which is conducive to dust landing, including a material guide trough upper body, a material guide trough lower body, and a dust suppression curtain. The dust suppression curtain includes a mounting plate and a dust suppression belt. The dust suppression curtain is installed on the right end of the lower end surface of the material guide trough upper body through the mounting plate. It also includes a baffle, a fan, and an air duct. Two baffles are vertically placed on the upper end surface of the material guide trough lower body. The fan and the air duct are both installed on the material guide trough upper body. While suppressing dust, it can provide a landing place for the raised dust to prevent the dust from falling into the material again and causing the dust to be raised again.

[0004] Based on the above situation, the inventors now believe that the current material guide chute is usually used in conjunction with a coal drop pipe. During the coal dropping process, the coal is likely to collide with the inside of the coal drop pipe, which is more likely to cause damage and dust adhesion to the inner wall of the pipe. At the same time, when the dust is too large, the surface of the filter is likely to adhere to coal ash and form blockage, and it is also difficult to deal with this phenomenon effectively and quickly when handling dust.

DETAILED DESCRIPTION

[0042] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The embodiment of the present invention specifically provides an air kinetic dust suppression material guide chute, please refer to 1, which includes a material guide chute body 1, a coal drop pipe 2, a loss reduction component 3, a dust exhaust component 4 and a driving component 5.

[0044] Among them, the bottom end of the coal dropping pipe 2 is fixedly connected to the guide trough body 1, and the guide trough body 1 includes a bottom plate 11, rollers 12, side plates 13, an arc cover 14 and a receiving bin 15. The bottom ends of the rollers 12 and the side plates 13 are fixedly installed on the bottom plate 11, and the side plates 13 are located on the upper surface of the rollers 12. The bottom end of the arc cover 14 remains fixed to the side plates 13, and the bottom end of the receiving bin 15 is fixedly connected to the arc cover 14, and the top of the receiving bin 15 is fixedly connected to the coal dropping pipe 2. After the coal falls into the coal dropping pipe 2, it will be sent to the rollers 12 through the receiving bin 15. The arc structure of the arc cover 14 can play a role in air expansion and pressure reduction. A slope bin 21 is provided on the coal dropping pipe 2 to impact and relieve the pressure on the fallen coal, and the kinetic energy of air and mechanical principles are used to improve the stability of raw material reception and the dust suppression effect.

[0045] Specifically, the loss reduction component 3 is installed on the slope bin 21 in a detachable manner. The loss reduction component 3 and the falling coal are buffered and connected. After wear, it can be quickly removed and replaced to increase the service life of the coal drop pipe 2. The dust exhaust component 4 is installed at the bottom end of the coal drop pipe 2. The dust exhaust component 4 can suck out the dust generated in the coal drop pipe 2 through negative pressure. The driving component 5 is fixedly connected to the outer side of the coal drop pipe 2. The dust exhaust component 4 is driven by the driving component 5 to suppress dust during transportation.

[0046] For further information, please refer to Figure 2 The loss reduction component 3 includes a buffer component 31 detachably connected to the slope bin 21 and an inflation component 32 connected to the buffer component 31 at the output end. When the coal falls, it can collide with the buffer component 31 and buffer the falling material. The inflation component 32 is used to inflate the buffer components in the buffer component 31 to ensure the buffering effect on the coal.

[0047] Please refer to Figure 3 and Figure 4 The bottom surface of the slope bin 21 is provided with an assembly opening 22, and the buffer assembly 31 includes a ring plate 311 installed on the outside of the assembly opening 22 by bolts, a first airbag 312 plugged with the assembly opening 22 on the outside, a second airbag 313 fixedly installed on the top surface of the slope bin, and a deflation nozzle 314 fixedly installed on the second airbag 313. The outside of the first airbag 312 is fixedly connected to the ring plate 311, and the deflation direction of the deflation nozzle 314 points to the first airbag 312. The first airbag 312 and the second airbag 313 are made of wear-resistant inflatable rubber. When coal falls, it will collide with the first airbag 312, and then be cushioned by the first airbag 312. If the activity potential energy of the coal is too large, the second airbag 313 can also have a cushioning effect, thereby reducing the impact and inhibiting the generation of coal ash. The ring plate 311 is bolted to the coal drop pipe 2. When the first airbag 312 is worn and needs to be replaced, the ring plate 311 can be removed from the coal drop pipe 2 to move the first airbag 312 out of the assembly port 22, so as to replace the worn first airbag 312.

[0048] In addition, when the surface of the first airbag 312 is stained with dust, the first airbag 312 can also be deflated. The deflation nozzle 314 is an electronic valve nozzle, so that the deflation nozzle 314 is opened and gas is ejected from the deflation nozzle 314, thereby spraying and cleaning the surface of the first airbag 312, thereby achieving the effect of quickly processing the coal ash and avoiding the blockage problem caused by the accumulation of coal ash.

[0049] Specifically, the inflation component 32 includes a first inflation tube 321 connected to the first airbag 312 at one end, and a three-way valve 322 connected to the other end of the first inflation tube. The remaining two ends of the three-way valve 322 are respectively connected to the air pump 325 and the second airbag 313 through the second inflation tube 323 and the third inflation tube 324. The air pump 325 is fixed on the outside of the coal drop pipe 2. The three inflation tubes 321 are of the type of hoses, which are convenient for loading and unloading of the first airbag 312. The air pump 325 inflates the first airbag 312 and the second airbag 312 through the three-way valve 322 to meet the needs of use.

[0050] For further information, please refer to Figure 5 The dust exhaust component 4 includes an installation bin 41 fixedly connected to the outer side of the coal drop pipe 2, a pressure column 42 and an adjusting rod 43 slidably arranged on the installation bin 41, a filter cartridge plugged into the outer wall of the coal drop pipe 2, and a rebound component for providing a reset force for the filter cartridge. The filter cartridge blocks large particles of coal so that dust can be sucked into the filter cartridge, and through the cooperation of the pressure column 42 and the adjusting rod 43, the filter cartridge can be moved and reset through the rebound component, thereby shaking off the coal ash attached to it to avoid clogging of the mesh port.

[0051] Specifically, the pressure column 42 includes a sliding column 421 that slides with the installation chamber 41 on the outside and a pressure head 422 fixed to the inner end of the sliding column 421. The sliding column 421 slides axially along the installation chamber 41 to drive the pressure head 422 to press the filter cartridge or separate from the filter cartridge.

[0052] Among them, the adjusting rod 43 includes a rod body 431 that is slidably connected to the mounting bin 41 on the outside, a guide rail 432 opened on the surface of the rod body 431, a fixing rod 433 whose bottom end is slidably matched with the guide rail 432, and a control component 434 arranged at the inner end of the rod body 431. The outer end of the rod body 431 is rotatably connected to the sliding column 421, and the mounting bin 41 at the top of the fixing rod 433 remains fixed. The middle section of the guide rail 432 is gradually tilted and extended along the circumference of the rod body 431, so that when a certain sliding column 421 moves outward, it will drive the rod body 431 to move outward synchronously, and when the guide rail 432 on the rod body 431 moves along the bottom end of the fixing column 433, it will gradually drive the rod body 431 to rotate along the inclined part until the rod body 431 rotates 90 degrees. When the rod body 431 is reset, it will be rotated and reset by the action of the guide rail 432.

[0053] Please refer to Figure 7A through opening 23 is provided on the outer wall of the coal dropping pipe 2, and the filter cylinder includes a cylinder body 441 which is slidably connected to the through opening 23 on the outside, a contact edge 442 which is fixed integrally to the cylinder body 441 on the outside, and a first filter screen 443 fixed on the cylinder body 441, and the contact edge 442 is kept in contact with the outer wall of the coal dropping pipe 2, and the cylinder body 441 is in contact with the inner end of the pressure head 422. During daily use, under the pressure of the pressure head 422, dust cannot penetrate too much from the first filter screen 443, and then, when cleaning is needed, the pressure head 422 moves outward, so that the dust can subsequently enter the inside of the installation bin 41 from the first filter screen 443 under the negative pressure.

[0054] When implementing, please refer to Figure 6 The control assembly 434 includes a control plate 435 fixed to the cylinder 441 at the bottom end, a movable hole 436 provided on the control plate 435, a shuttle bar hole 437 provided in the movable hole 436, a protruding rod 438 fixed coaxially with the rod 431 at one end, and a clamping plate 439 fixed integrally to the outer side of the protruding rod 438. The clamping plate 439 is staggered with the shuttle bar hole 437, so that when the rod 431 moves outward, it will first pass through the staggered clamping plate 439. Pull the control plate 435 and make the cylinder 441 slide outward in the opening 23. After the rod 431 rotates 90 degrees under the action of the guide rail 432, the clamping plate 439 will rotate synchronously and separate from the control plate 435, so that the cylinder 441 rebounds and resets through the rebound assembly, hitting the first filter 443 to avoid blockage. After the rod 431 moves and resets, the clamping plate 439 will rotate and reset, and the above steps will be repeated.

[0055] Please refer to Figure 5 The rebound assembly includes a synchronization block 451 fixed to the outside of the cylinder 441, a telescopic rod 452 fixedly connected to the synchronization block 451 at one end, a support 453 slidably connected to the other end of the telescopic rod 452, and a spring 454 installed between the synchronization block 451 and the support 453. The outer side of the support 453 is fixed to the installation bin 41, so that when the cylinder 441 moves outward, the spring 454 is compressed, so that when the cylinder 441 needs to be reset, it can be quickly reset by the spring 454.

[0056] For further information, please refer to Figure 5 The driving component 5 includes a moving component connected to the sliding column 421 and a negative pressure component connected to the installation bin 41. The moving component drives the sliding column 421 to move, and the negative pressure component forms a negative pressure wind force to absorb dust, so as to quickly drive the transported dust to be discharged into the interior of the material guide trough body 1 in a circulating manner, and absorb and suppress dust for a second time.

[0057] For details, please refer to Figure 3 and Figure 5The moving component includes a support arm 511 whose one end is fixed to the sliding column 421, a push frame 512 fixedly connected to the other end of the support arm 511, a drive box 513 fixed to the outer side of the coal drop pipe 2 and a motor 514 fixed to the drive box 513. The electric motor 514 provides a driving force for the push frame 512, so that the push frame 512 can move away from the drive box 513 or move close to the drive box 513, thereby driving the sliding column 421 to move outward or inward on the installation bin 41.

[0058] The negative pressure assembly includes a conveying pipe 521 whose top is fixedly connected to the installation bin 41, a dust collecting bin 522 fixedly connected to the conveying pipe 521, an air duct 523 fixedly connected to the dust collecting bin 522 at one end, and a fan 524 fixedly connected to the other end of the air duct 523. The exhaust port of the fan 524 is connected to the material guide trough body 1, so as to form a dust suppression internal circulation in the material guide trough body 1 and the coal drop pipe 2.

[0059] The bottom end of the fan 524 is fixed to the arc cover 14, the outer side of the dust suction bin 522 is fixedly connected to the coal drop pipe 2, and a second filter screen 525 is fixedly arranged inside the dust suction bin 522. Negative pressure is formed inside the dust suction bin 522 by the fan 524, and after the pressure head 422 moves outward, the dust is sent into the installation bin 41 through the first filter screen 443, and finally filtered by the second filter screen 525, so that the treated gas is discharged from the fan 524 into the guide trough body 1 for a second time, forming a dust suppression cycle, and a detachable guard plate can be provided on the dust suction bin 522 to facilitate quick treatment when there is a lot of dust accumulated inside the dust suction bin 522. In this way, a negative pressure space can also be quickly formed in the dust suction bin 522. When the first filter screen 443 is opened, the dust inside the coal drop pipe 2 whose internal air pressure increases due to the falling of coal can be quickly flowed into the first filter screen 443 for discharge, so as to improve the treatment effect of coal ash.

[0060] When implementing, please refer to Figure 8 A gear 515 is rotatably installed inside the driving box 513, and the upper and lower sides of the gear 515 are respectively meshed with a rack 516. The racks 516 are each fixedly connected to a push frame 512 through a synchronous frame 517. The outer side of the push frame 512 is slidably connected to the driving box 513. The gear 515 is coaxially fixed with the output shaft of the motor 514, so that the motor 514 drives the gear 515 to rotate, and the rack 516 drives the two push frames 512 to move away from or closer to each other.

[0061] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
