Description

Technical Field

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

[0002] The air kinetic dust suppression chute is based on the principles of aerodynamics and fluid mechanics. It reduces the pressure of the air flow in the chute by expanding the capacity and releasing the pressure, so as to get rid of the problem of dust pollution in the space when the conveying system is operating at the material point.

[0003] The existing Chinese patent with announcement number CN210619639U discloses a dust suppression material guide trough that 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. The 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 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 dust and form blockage, and it is also difficult to deal with this phenomenon effectively and quickly when handling dust. Summary of the Invention

[0005] The purpose of the present invention is to provide an air kinetic energy dust suppression material guide chute, which has the effects of buffering falling materials, reducing damage and dust sticking, and reducing dust suppression blockage of filter screens.

[0016] By adopting the above technical solution, when a certain sliding column moves outward, it will drive the rod body to move outward synchronously.

[0017] The present invention is further configured as follows: a through opening is opened on the outer wall of the coal drop pipe, the filter cylinder includes a cylinder body slidably connected to the through opening on the outside, a contact edge fixed integrally to the cylinder body on the outside, and a first filter screen fixed on the cylinder body, the contact edge is kept in contact with the outer wall of the coal drop pipe, and the cylinder body is in contact with the inner end of the pressure head.

[0018] By adopting the above technical solution, under the pressure-driven isolation of the pressure head, dust cannot penetrate too much into the first filter screen, and then.

[0019] The present invention is further configured as follows: the control component includes a control plate whose bottom end is fixed to the cylinder, a movable hole opened on the control plate, a shuttle bar hole opened in the movable hole, a convex rod coaxially fixed to the rod body at one end, and a clamping plate integrally fixed to the outer side of the convex rod, the clamping plate and the shuttle bar hole are kept misaligned, and the rebound component includes a synchronization block fixed to the outer side of the cylinder, a telescopic rod fixedly connected to the synchronization block at one end, a support slidably connected to the other end of the telescopic rod, and a spring installed between the synchronization block and the support.

[0029] 2. During transportation, the materials are cushioned by the cooperation between the air bags. The inflation and deflation of the air bags are simple to operate. When adhesion occurs, the air bags can be self-cleaned by deflation to reduce the stickiness of the internal materials. At the same time, the cleaning time is reduced, the downtime is short, and it is beneficial to ensure the operation efficiency.

[0030] 3. When dust is generated during transportation, the negative pressure outside the first filter can be used for circulating dust suppression to achieve the dust suppression effect. The negative pressure space is formed in the dust suction bin outside the guide chute and the coal drop pipe. The filter can be blocked and separated by the pressure head to enhance the air pressure in the coal drop pipe, thereby increasing the rate at which dust is discharged through the first filter and improving the dust collection effect.

[0031] 4. When the pressure head moves, the first filter can be driven by the control component, so that the first filter can shake off the dust adhering to the surface to achieve the effect of automatic dredging and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0043] The embodiment of the present invention specifically provides an air kinetic energy dust suppression material guide chute, please refer to figure 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 drive 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 of 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 is used to buffer the falling coal and can be quickly removed and replaced after wear, thereby increasing 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 drive component 5 is fixedly connected to the outside of the coal drop pipe 2. The dust exhaust component 4 is driven by the drive component 5 to suppress dust during transportation.

[0046] Further, 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 buffer components in the buffer component 31 are inflated through the inflation component 32 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. 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 into the assembly opening 22 on the outside, a second airbag 313 fixed 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. 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 potential energy of the coal is too large, the second airbag 313 can also play a cushioning effect, thereby reducing the impact and suppressing 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 that the worn first airbag 312 can be replaced.

[0048] In addition, when the surface of the first airbag 312 is stained with dust, the first airbag 312 can also be deflated to shrink. The deflation nozzle 314 is an electronic valve nozzle, which opens the deflation nozzle 314 and allows gas to be ejected from the deflation nozzle 314, thereby blowing and cleaning the surface of the first airbag 312, 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 facilitates the 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] Further, please refer to Figure 5 The dust exhaust component 4 includes an installation bin 41 fixedly connected to the outside of the coal drop pipe 2, a pressure column 42 and an adjusting rod 43 slidingly 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 mutual 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 it from the filter cartridge.

[0052] The adjusting rod 43 includes a rod body 431 slidably connected to the mounting chamber 41 on the outer side, a guide rail 432 provided 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 post 421, and the mounting chamber 41 at the top of the fixing rod 433 remains fixed. The middle section of the guide rail 432 gradually tilts and extends along the circumference of the rod body 431, so that when the sliding post 421 moves outward, the rod body 431 is driven to move outward synchronously, and the guide rail 432 on the rod body 431 moves along the bottom end of the fixed post 433, and gradually drives 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 is 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 drop pipe 2. The filter cartridge includes a cylinder body 441 that is slidably connected to the through opening 23 on the outside, a contact edge 442 that is fixed integrally to the cylinder body 441 on the outside, and a first filter screen 443 that is fixed on the cylinder body 441. The contact edge 442 is kept in contact with the outer wall of the coal drop 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 into the first filter screen 443. Then, when cleaning is needed, the pressure head 422 moves outward, so that the dust can subsequently enter the interior 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 its 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. Then, 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 component, 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 chamber 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 guide trough body 1 in a circulating manner, and absorb and suppress dust for the second time.

[0057] For details, please refer to Figure 3 and Figure 5The moving assembly 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 driving force for the push frame 512, so that the push frame 512 can move away from or close to the drive box 513, 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 fixedly connected to the installation bin 41 at the top, a dust collection bin 522 fixedly connected to the conveying pipe 521, an air duct 523 fixedly connected to the dust collection 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 guide chute body 1, thereby forming a dust suppression internal circulation in the guide chute body 1 and the coal drop pipe 2.

[0059] The bottom end of the fan 524 is kept fixed to the arc cover 14, the outer side of the dust collection bin 522 is fixedly connected to the coal drop pipe 2, and a second filter screen 525 is fixedly arranged inside the dust collection bin 522. The fan 524 forms a negative pressure inside the dust collection bin 522, 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 chute body 1 for the second time, forming a dust suppression cycle. A detachable guard plate can be provided on the dust collection bin 522 to facilitate quick treatment when there is a lot of dust accumulated inside the dust collection bin 522. In this way, a negative pressure space can also be quickly formed in the dust collection 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 coal can be quickly flowed into the first filter screen 443 for discharge, so as to improve the treatment effect of the coal ash.

[0060] When implementing, please refer to Figure 8 A gear 515 is installed inside the drive box 513 for rotation, and the upper and lower sides of the gear 515 are respectively engaged with a rack 516. The racks 516 are fixedly connected to a push frame 512 through a synchronization frame 517. The outer side of the push frame 512 is slidably connected to the drive 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. Therefore, the control method and wiring layout are no longer explained in detail in the present invention.

[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 principles of the present invention should be included in the scope of protection of the present invention.
