Compared with the prior art, the utility model has the advantages of it is obvious, following five parts that fall into explains five devices respectively and compares the advantage that current equipment has:
1. a material guide groove body: when the bulk material falls from the head of the upstream belt conveyor, the bulk material falls onto the conveying belt through the material falling barrel, the tail part of the conveying belt is sealed by the tail sealing device, the dusty air flow and the material flow move along the running direction of the conveying belt together and pass through the primary circulating pressure relief device, meanwhile, the dust-containing airflow is blocked by the damping device to form force mutual interference, the positive pressure airflow is guided to circulate in the first-stage circulating pressure relief device to balance the pressure and continuously pass through the damping device, the multi-stage damping device has an adsorption effect on the passing dust, a large amount of dust is adhered to agglomerate, automatically fall off under the disturbance of material flow, and are taken away along coal flow, and when the coal flows through the secondary circulation pressure relief device, and the incomplete pressure-relief air volume of the first-stage pressure-relief device is continuously treated until the outlet of the device, so that the positive pressure impact air flow generated by the falling of the material is reduced to the position below the belt speed of the belt conveyor, and the aim of dust removal is fulfilled. The guide chute body can automatically remove dust, and the positive pressure airflow generated by the falling of the materials in the transfer island is guided to circulate and block the airflow by utilizing the aerodynamic principle, so that the automatic dust removing principle is formed, and an external power source is not needed; can also prevent the phenomenon of detonation, transport the whole internal circulation of the automatic dust suppression device in island, structural design is reasonable, does not block up the passageway, prevents the dust degree of depth increase, avoids the phenomenon of detonation.
2. Tail sealing device: the tail sealing device is provided with three-stage sealing, so that dust at the tail of the guide chute body is prevented from overflowing, and the multi-stage sealing gradually weakens the air pressure in the guide chute, so that a small amount of dust-free gas overflows at the tail, dust is fully controlled, and the purpose of dust suppression is achieved. The tail curtain block is contacted with the surface of the conveying belt without damaging the surface of the belt, and the formed part is adapted to the surface of the belt to perform self-compensation sealing, thereby achieving the purpose of dust suppression.
3. Tail drainage device: in the application process of the unpowered dust removal device for the belt conveyor of the bulk conveying system transfer station, a power plant or a wharf belt conveyor is partially arranged in the open air, when a rainy season comes, the belt conveyor at the initial stage of no-load operation can be brought into a guide chute at the tail part of the next belt conveyor of the transfer station due to belt surface accumulated water, the sealing effect of the unpowered dust removal guide chute equipment and the belt surface of the belt conveyor is tight, accumulated water cannot be discharged, even if the belt conveyor is stopped, the accumulated water cannot be discharged out of the belt surface due to the arrangement of the inclination angle on the basis of the belt conveyor, and the normal operation of the belt conveyor is directly. The tail sealing drainage device can solve the problems, when drainage is needed, only the driving part needs to be started to push the push rod assembly to move, the tail check curtain is unfolded through the rotating mechanism, a gap is formed between the tail check curtain and the conveying belt, the drainage function is realized, and the difficulty in drainage is solved. After the drainage is finished, the tail baffle curtain can realize automatic recovery sealing, the sealing effect can be effectively guaranteed when the drainage is not needed, and the dust is prevented from overflowing from the tail of the guide chute.
4. Return belt face belt cleaning device: in the process of transferring a bulk material conveying system, after materials are discharged from a discharging roller, the materials attached to the surface of a conveying belt cannot be cleaned, and the phenomenon is called belt return belt material. The belt return belt material is generated in all belt conveyor systems, and along with the increase of the belt conveyor capacity and the high belt speed, the belt return belt material is increased, which directly causes the harm to the environment, the personnel health and the service life of equipment, and simultaneously increases a large amount of maintenance cost. The device utilizes a small amount of water source to moisten the coal slime adhered to the surface of the return belt through the softening and spraying part with the fan-shaped nozzle, and then the water slime enters the first cleaning part, the second cleaning part, the third cleaning part and the fourth cleaning part, the scraper type cleaning part thoroughly scrapes the materials on the conveying belt by using the scraper made of special materials, the conveying belt is not damaged, the scraped materials can fall into the collector, and the recovery drain outlet is arranged below the collector, so that the materials can be recovered in a centralized manner; after the four cleaning parts, the belt surface of the conveying belt is dried by compressed air through the nozzle of the quick drying part, so that the purposes of removing the adhesive on the conveying belt, ensuring that the return belt does not carry coal and dust in the running process and improving the cleaning effect of the conveying belt are achieved quickly.
5. Intermittent spraying device: in coal conveying system transfer station belt feeder dust suppression control field, there are a lot of dust removals or dust suppression mode, the position of conveyer belt afterbody driven roll has often been neglected to traditional design mode, because conveyer belt bulk cargo transport bulk cargo distance is very far, the return stroke area can be stained with some tiny materials to afterbody cylinder department during operation material, rotate through afterbody cylinder and constantly exert pressure, the granule is compelled to grind into finer dust granule, the afterbody cylinder drives the dust raise when rotating to produce raise dust excessive, pollute the surrounding environment, influence staff physical and mental health. The gap type spraying device is a dust suppression device specially designed for the region, dust suppression is carried out on generated dust through a universal joint spraying assembly arranged at the front center of the tail roller, and the dust flying problem of the tail roller is solved. And owing to there is the setting of switch board, spraying time and interval time can freely be adjusted, can set for spraying time and dwell time according to conveyer belt operating cycle, avoid the too big other accidents that arouse of spraying volume.
