Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection facilities, and in particular relates to a micron-level dry mist dust suppression device for a belt conveyor. Background Art

[0002] During the material transfer process, induced airflow is generated in the material chute and the guide chute of the receiving belt conveyor due to the height difference, and the dust generated by the induced material overflows from the gaps in the chute and the guide chute and flies into the transfer station. When the belt conveyor is working, the material falls from the head of the belt conveyor, causing disturbed airflow inside the chute, and small particles of material are lifted up by the airflow to generate dust; during the falling process of the material, collisions occur between material particles and between the material and the chute, intensifying dust generation; under the action of disturbed airflow, the dust flies and overflows along the gap between the belt conveyor and the head of the chute, and a dry fog dust suppression device will be used.

[0003] In the Chinese patent with publication number CN105346985B, a micron-level dry fog dust suppression device for a belt conveyor is mentioned. The diameter of the droplet particles sprayed by the invention is 1 to 10 μm, which can effectively control the dust in the process of coal ash transportation in the coal field, ensure the cleanliness of the site environment, and protect the health of the on-site workers;

[0004] In the Chinese patent with publication number CN221643681 U, a dust removal mechanism and an imported coal conveying system are mentioned. The water is highly atomized at the resonance nozzle through the sonic boom of high-frequency sound waves, and fine water mist particles below 10 μm are generated and sprayed to the dust generating point, so that the water mist particles and dust particles collide, adhere, and agglomerate to increase, and settle under the action of their own gravity, so as to achieve the effect of dust suppression. The pad can absorb the vibration generated by the oscillating part when it is working as much as possible, reduce the shaking of the column, and make it easier to connect the first reinforcement plate and the second reinforcement plate through the connecting head and the connecting groove, so as to facilitate the reinforcement and fixation of the resonance nozzle;

[0005] The existing dry mist dust suppression device for belt conveyors, although it successfully produces micron-level dry mist for dust suppression by spraying a mixture of gas and liquid through a water pump and an air pump, and this device has achieved good results in the conveying part of the middle section of the belt conveyor, it still faces severe challenges at both ends of the belt conveyor, especially in the transition area where materials fall from one belt conveyor to another. Specifically, when materials fall from the high point of one belt conveyor to the low point of another belt conveyor, due to the height difference, a strong induced airflow will be generated in the feed hopper or the connection box. This airflow not only accelerates the falling speed of the material, but also causes violent collisions between material particles and between the material and the funnel wall, thereby releasing a large amount of dust. Under the action of the induced airflow, these dusts are very easy to fly out along the feed port of the funnel or the connection box, and spread throughout the entire transfer station, causing serious environmental pollution and safety hazards.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention cooperates with the pre-dust suppression mechanism, the dust suction mechanism and the connection box, and can guide the material in sequence through the guide block 1, the guide block 2 and the guide block 3 during the material transfer process to ensure that the material can slide smoothly onto the belt conveyor, which not only reduces collisions and controls the direction of dust, but also cooperates with the dry mist sprayed by the dry mist nozzle to suppress the raised dust, thereby achieving pre-dust suppression of dust, reducing the amount of dust entering the belt conveyor, and thereby increasing the overall dust suppression capacity and improving the dust suppression effect.

[0020] 2. The present invention cooperates with the dust collection mechanism, driving mechanism, pump body, filter box and collection box. After the dry mist absorbs the dust of the material, it can be guided to the inside of the dust collection box, and the dry mist can be condensed into liquid through the heat-conducting louvers with lower temperature. After being collected and filtered by the filter box, it is transported back to the dust collection box to cool the heat-conducting louvers, which not only improves the resource utilization rate but also can collect dust.

[0021] 3. Through the cooperation of the pre-dust suppression mechanism, the dust collection mechanism and the driving mechanism, when the dust enters the dust collection box and is condensed by the heat-conducting louvers, the operation of the servo motor can cause the beating block to beat the part of the heat-conducting louvers located in the water-cooling chamber, thereby generating vibration and accelerating the falling of the liquid after condensation.

[0022] 4. The present invention cooperates with the pre-dust suppression mechanism, dust suction mechanism and driving mechanism. During the process of materials being smoothly guided and buffered by guide block one, guide block two and guide block three in sequence, if too much material is accumulated on the top of guide block two, the material will push the push plate, thereby causing the cross bar to move toward the middle, so that the roller will tighten belt two, so that the driving shaft can drive the eccentric wheel to rotate through belt two, thereby causing the vibration component to vibrate above guide block two to accelerate the flow of materials. At the same time, the sensor will also control the operation of the driving motor through feedback from the external PLC, thereby controlling the guide block one to move upward and reducing the amount of material entering. This not only avoids the inability to pre-suppress dust due to excessive material, but also controls the conveying volume to improve adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In this embodiment, the beating block 54 is composed of a mounting block and a rubber block, wherein the rubber block is in contact with the heat-conducting louver 45, so that when the belt 1 53 rotates with the beating block 54, the beating block 54 will beat the heat-conducting louver 45, thereby allowing the liquid condensed on the surface of the heat-conducting louver 45 to drip quickly, and also prevent some dust from adhering to the surface of the heat-conducting louver 45, so that the dry mist sprayed by the dry mist nozzle 317 has more time to contact with the dust for dust suppression; belt pulleys are installed at both ends of the driving shaft 52, and a pulley is also located inside the water-cooling chamber 43, and the pulley is used to connect with the belt 1 53, so that the belt 1 53 can be movably connected to the inside of the water-cooling chamber 43; the eccentric wheel A pulley is also provided on one side of 56, but the pulley contacts the inner side of belt 2 55 from the beginning, but not tightly. Therefore, when the servo motor 51 is in operation, it will only rotate belt 1 53 through belt 1 53. Only when there is material piled up above guide block 2 315, the two cross bars 323 will approach each other, so that the roller 326 pulls belt 2 55, and then the eccentric wheel 56 will rotate after the belt 2 55 is tightened, thereby allowing the vibration assembly 33 to vibrate up and down as a whole. In addition, the pulley of the eccentric wheel 56 is unidirectional, so when material hits the vibration inclined plate 331 above the guide block 2 315, it will not affect the eccentric wheel 56.

[0065] Reference Figure 7-Figure 8 In a further embodiment, a screen 48 is provided on the upper port of the guide collection chamber 44 and one side of the heat conduction louver 45, a baffle 47 is provided at the port of the dust suction groove 42, and a guide nozzle 46 for diversion is installed inside the guide collection chamber 44.

[0066] In this embodiment, the screen 48 is used to block small materials, and the blocking net 47 is used to block large materials, and a slope is provided at the bottom of the dust suction groove 42 port, so that small materials that have entered the dust suction groove 42 can be guided back to the interior of the pre-dust suppression mechanism 3; the guide nozzle 46 is connected to an external air pump, which can spray out high-pressure airflow and flow to the interior of the filter box 7 through the connecting pipe at the bottom of the guide collection chamber 44, thereby generating a certain negative pressure at the upper port of the guide collection chamber 44 and the interior of the dust suction groove 42, thereby attracting dry mist.

[0067] Reference Figure 2 , Figure 8 and Fig. 9 In a further embodiment, one side of the water cooling chamber 43 and the bottom of the guide collection chamber 44 are connected to the filter box 7 through a hose.

[0068] In this embodiment, a vent is provided on one side of the filter box 7 to facilitate the discharge of the high-pressure airflow ejected from the guide nozzle 46; there is also a drawer on one side of the filter box 7 for installing a filter plate, which is used to filter the liquid containing dust, and the filtered liquid will enter the interior of the collection box 8.

[0069] Reference Figure 2 and Fig.13 In a further embodiment, a connecting pipe is provided at the output end of the pump body 6 for injecting liquid into the water cooling chamber 43, and the input end of the pump body 6 is connected to the collecting box 8, and the filter box 7 is fixedly connected above the collecting box 8 and is interconnected.

[0070] In this embodiment, the liquid collected in the collection box 8 can be transported to the water tank of the dry mist mechanism 2 for utilization through more sophisticated filtration.

[0071] The working principle of the present invention is as follows:

[0072] When two belt conveyors are butted end to end, the bottom of the connection box 9 of one belt conveyor is connected to the feeding top plate 311 of the other belt conveyor through a dust bag. At this time, when the material enters the pre-dust suppression mechanism 3 of the other belt conveyor from the connection box 9 of one belt conveyor,

[0073] At this time, the material will be guided by the guide block 1 314, the guide block 2 315 and the guide block 3 316 in sequence. The generation of dust will be reduced during the guiding process, so that the material can smoothly enter the conveyor 1 and then pass through the dry mist mechanism 2 in the middle part of the conveyor 1 for dust suppression. When the material is smoothly buffered and guided by the guide block 1 314, the guide block 2 315 and the guide block 3 316 in sequence, the generated dust will be suppressed by the dry mist sprayed from the dry mist nozzle 317. Since the guide nozzle 46 is connected to the external air pump and blows toward the bottom of the guide collection chamber 44, the dust suction groove 42 connected to the top of the guide collection chamber 44 is generated. A certain negative pressure will cause the dust-suppressed dry mist to enter the dust suction groove 42 and contact the heat-conducting louvers 45 with a lower temperature, thereby condensing the dry mist into a liquid containing dust. The liquid is guided to the bottom by the inclined heat-conducting louvers 45 and enters the guide collection chamber 44, and then is transported to the inside of the filter box 7 by a pipeline. After being filtered by the filter screen inside the filter box 7, it will enter the inside of the collection box 8. Therefore, in the process of material transfer between the two belt conveyors, not only can the material be smoothly transported, but also the dust in the transportation process can be suppressed, so as to achieve the purpose of pre-dust suppression, and the dust-suppressed dry mist will be filtered and utilized;

[0074] After the dry mist is collected in the collecting box 8, it will be transported to the water cooling chamber 43 opened in the dust collecting box 41 through the pump body 6, so as to maintain the temperature of the heat conducting louver 45. At the same time, the external PLC can control the operation of the servo motor 51 to make the driving shaft 52 rotate with the belt 1 53, and let the beating block 54 fixed on the outer periphery of the belt 1 53 beat one end of the heat conducting louver 45, so as to accelerate the liquid condensed on the surface of the heat conducting louver 45 to fall;

[0075] When too much material is conveyed or conveyed too fast and causes the material to accumulate above the guide block 315 after passing the guide block 1 314, the docked material will push the push plate 321, so that the inclined plug block 322 is inserted into the inside of the slot 325, so that the two cross bars 323 begin to move closer to each other, thereby allowing the roller 326 at one end of the cross bar 323 to move inside the dust collection box 41, thereby tightening the belt 2 55, so that the belt 2 55 will closely contact one end of the drive shaft 52 and the roller 326 and the eccentric wheel 56, so that the rotation of the drive shaft 52 can be achieved through the belt 2 55. The eccentric wheel 56 rotates, so that the connecting rod 57 and the vibration assembly 33 vibrate up and down as a whole, so that the materials accumulated on the guide block 315 slide down quickly. At the same time, due to the push of the push plate 321, the sensor 327 contacts the support plate 312, thereby generating an electrical signal to feed back to the PLC, so that the PLC can operate the drive motor 34 to operate, and then the rotation of the drive rod 35 drives the guide block 314 to move up, thereby controlling the amount of material entering until the material is no longer accumulated, and at the same time, the guide block 314 can be moved down to increase the conveying amount;

[0076] When negative pressure is generated inside the dust suction groove 42 and the material is guided sequentially through the guide block 1 314 , the guide block 2 315 and the guide block 3 316 , some large particles of the material will be blocked by the blocking net 47 , while small particles of the material will be blocked by the screen 48 , thereby preventing the material from entering the guide collection chamber 44 .

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
