Description

Technical Field

[0001] This invention belongs to the field of dust suppression equipment technology, and in particular relates to a dry fog dust suppression device for a bulk material stacking and loading integrated machine. Background Technology

[0002] The bulk material stacking and loading machine adopts a combined design of chain conveyor and telescopic belt conveyor. The chain conveyor has strong load-bearing capacity and can adapt to large impurities and mixed materials of multiple particle sizes that may be contained in the bulk materials. Moreover, the chain structure has excellent sealing performance, which can effectively prevent the material from spilling during the lifting process. The telescopic belt conveyor can flexibly adjust its length and working angle to meet the loading operation needs of ships of different tonnages and also meet the height and range adjustment needs during stacking operations. The two work together to ensure the continuity of material transportation and the adaptability of the scene, and significantly improve the overall operation efficiency. For example, after a truck dumps bulk materials onto the bottom of the chain conveyor, the chain conveyor achieves stable lifting and bearing of the materials through continuous operation, and then accurately transfers the materials to the telescopic belt conveyor. Finally, the telescopic belt conveyor flexibly completes the loading or stacking operation according to the on-site operation needs.

[0003] However, there are clear high-incidence points for dust in the entire process of conveying bulk materials in the integrated machine. The first is the impact dust when the material is dumped from the truck to the bottom of the chain conveyor. The second is the drop dust when the chain conveyor is transferred to the telescopic belt conveyor. The third is the airflow disturbance dust when the material is discharged from the side of the telescopic belt conveyor. Small particles are easy to disperse because, on the one hand, when the material is impacted, dropped, or discharged, it detaches from the conveyor belt or the main material body after colliding with it. Affected by airflow disturbance, the lighter small particles (especially fine powder with a particle size of less than 10μm) are easy to detach from the main material body and form dust. On the other hand, the natural airflow at the work site or the airflow generated by the operation of the equipment will further aggravate the diffusion of small particles, which not only causes material waste, but also causes pollution to the surrounding environment.

[0004] Currently, the industry mostly uses ordinary spraying dust suppression measures to address this problem. However, the droplet size of ordinary spraying is relatively large (usually greater than 50μm), resulting in a low probability of contact and collision with small dust particles, poor agglomeration effect, incomplete dust suppression, and reduced overall operational reliability and dust suppression effect of the equipment.

[0005] In addition, existing dust suppression measures are mostly based on fixed parameters and cannot be dynamically adjusted according to the actual dust concentration on site. This often results in insufficient dust suppression, leading to the dispersion of small particles, which pollutes the environment, wastes materials, and significantly restricts the stability of dust suppression effect during the transfer of bulk materials.

[0006] To address these issues, we propose a dry fog dust suppression device for a bulk material stacking and loading integrated machine. Summary of the Invention

The side walls of the rubber positioning strips are fixedly connected to universal serpentine tubes. The top end of the universal serpentine tubes is fixedly fitted with a dust concentration sensor.

[0017] In the aforementioned dry fog dust suppression device for a bulk material stacking and loading integrated machine, the structures of the dry fog dust suppression mechanism in the transfer section and the dry fog dust suppression mechanism in the discharge section are consistent with the structure of the dry fog dust suppression mechanism in the loading section.

[0018] In the aforementioned dry fog dust suppression device for a bulk material stacking and loading integrated machine, the first dust collection mechanism includes an adjustable electric valve fixedly connected to the bottom of the filter box. The air inlet end of the adjustable electric valve is fixedly connected to a first connecting pipe. The air inlet end of the first connecting pipe is fixedly connected to a hollow block. The outer wall of the hollow block is fixedly connected to four second connecting pipes. The air inlet ends of the four second connecting pipes are all fixedly connected to a dust collection hood. An L-shaped fixing frame is fixedly sleeved on the outer wall of the dust collection hood.

[0019] In the aforementioned dry fog dust suppression device for a bulk material stacking and loading integrated machine, the structures of the second and third dust suction mechanisms are consistent with the structure of the first dust suction mechanism.

[0020] Compared with existing technologies, the advantages of a dry fog dust suppression device for a bulk material stacking and loading integrated machine are:

[0021] 1. The integrated bulk material stacking and loading machine, equipped with a water tank, water treatment mechanism, dry fog dust suppression mechanism for the feeding section, dry fog dust suppression mechanism for the transfer section, and dry fog dust suppression mechanism for the discharging section, first moves the dry fog dust suppression device to the dust suppression position before operation. Then, the feeding section dry fog dust suppression mechanism, the transfer section dry fog dust suppression mechanism, and the discharging section dry fog dust suppression mechanism are arranged at the corresponding dust suppression points of the integrated bulk material stacking and loading machine using a support frame. When the integrated bulk material stacking and loading machine is conveying bulk materials, the operator controls the micro water pump, air compressor, normally closed solenoid valve, three-way reversing solenoid valve, and air extraction pump through the PLC controller inside the dry fog box controller. The air compressor fills the air tank with sufficient... Sufficient high-pressure air is used to carry the clean water from the water treatment unit to each dry fog dust suppression unit. The water is then sprayed out through the atomizing nozzles of each unit, creating a dry fog effect. Following the control commands of the dry fog dust suppression equipment, the water is sprayed onto the dust suppression points of the bulk material stacking and loading machine. The dry fog interacts with and collides with the dust particles, causing them to adhere, agglomerate, and grow larger. Under their own gravity, the particles settle, thus achieving dust suppression. This ensures the device provides continuous and efficient dust suppression for the bulk material stacking and loading machine, preventing the waste and environmental pollution caused by the dispersion of small particles, and improving the reliability of the dry fog dust suppression device.

[0022] 2. Through the established dust concentration sensors, dust purification mechanisms, first dust collection mechanism, second dust collection mechanism, and third dust collection mechanism, when the dry fog dust suppression mechanisms in the feeding section, transfer section, and discharge section are in use, the dust concentration sensors in each dry fog dust suppression structure detect the dust concentration at each dust suppression point and convert the dust concentration into an electrical signal, which is then fed back to the PLC controller in the dry fog chamber controller. The PLC controller in the dry fog chamber controller controls the opening and closing of the adjustable electric valves in the first, second, and third dust collection mechanisms based on the feedback dust concentration. This is because the dust concentration at each dust suppression point of the bulk material stacking and loading integrated machine is not constant, but the maximum suction power of the air pump is fixed. To ensure the dust suppression effect at each dust suppression point, it is necessary to dynamically adjust the suction effects of the first, second, and third suction mechanisms to avoid the escape of small particulate bulk materials that pollute the environment and cause waste. This allows the dry fog dust suppression device to have the function of absorbing and filtering escaped small particulate bulk materials, avoiding the problem of small particulate bulk materials drifting and causing waste and environmental pollution, thus improving the effectiveness and reliability of the dry fog dust suppression device.

[0023] 3. Through the dust purification mechanism, the first dust collection mechanism, the second dust collection mechanism, and the third dust collection mechanism, when the bulk material stacking and loading machine is used to stack or load bulk materials that are easily perishable when exposed to water (such as cement clinker, grain, etc.), the air pump is directly started by the PLC controller in the dry fog box controller. The air pump works in conjunction with the dust purification mechanism, the first dust collection mechanism, the second dust collection mechanism, and the third dust collection mechanism to collect small particles of bulk material floating at the dust suppression point of the bulk material stacking and loading machine. This prevents moisture from damaging the bulk materials that are easily perishable when exposed to water, effectively improving the adaptability of the dry fog dust suppression device to the characteristics of bulk materials. Even when facing bulk materials that are easily perishable when exposed to water, the device has a highly efficient and stable dust suppression effect, improving the safety of bulk material transportation and the reliability of the device.

[0040] The air pump 37, adjustable electric valve 71, micro water pump 104, air compressor 11, normally closed solenoid valve 13, three-way reversing solenoid valve 19, and water replenishment solenoid valve 22 are electrically connected to the output terminal of the PLC controller inside the dry fog chamber controller 17 via wires; the dust concentration sensor 47, air pressure sensor 12, and liquid level sensor 21 are electrically connected to the input terminal of the PLC controller inside the dry fog chamber controller 17 via wires. The above-mentioned electrical components and electrical connections are existing technologies and will not be described in detail here.

[0041] The operating principle of this invention is described as follows: Before the bulk material stacking and loading machine starts working, the dry fog dust suppression device is first moved to the dust suppression position. Then, the dry fog dust suppression mechanism 4 of the feeding section is fixed above the feeding position of the bulk material stacking and loading machine by the bracket. The rubber positioning strip 45 is bent and fixed to ensure that the multiple atomizing nozzles 44 in the feeding section dry fog dust suppression mechanism 4 are arranged in a ring, so that the dry fog from the multiple atomizing nozzles 44 forms a "conical" dry fog wall above the dust suppression point. At the same time, the four dust collection hoods of the first dust suction mechanism 7 are fixed by the bracket. 75 are respectively arranged on the four sides of the feeding position of the bulk material stacking and loading machine. Then, the dust concentration sensor 47 is arranged above the feeding section of the bulk material stacking and loading machine through the bent universal serpentine tube 46 to detect the dust concentration here. In the same arrangement method, the dry fog dust suppression mechanism 5 of the transfer section and the second dust suction mechanism 8 are arranged at the joint between the chain plate conveyor and the telescopic belt conveyor of the bulk material stacking and loading machine. The dry fog dust suppression mechanism 6 and the third dust suction mechanism 9 of the discharge section are arranged at the side discharge position of the bulk material stacking and loading machine.

[0042] When the bulk material stacking and loading machine is conveying bulk materials, the staff can start the dust suppression device through the dry fog box controller 17. Specifically, the PLC controller inside the dry fog box controller 17 controls the micro water pump 104, air compressor 11, normally closed solenoid valve 13, three-way reversing solenoid valve 19 and air pump 37 to work.

[0043] After the air compressor 11 and the three-way reversing solenoid valve 19 are energized, the three-way reversing solenoid valve 19 connects the second air pipe 20 to the air inlet of the air compressor 11. Under the suction action of the air pump 37, the outside air is purified by the dust purification mechanism 3 and enters the air inlet of the air compressor 11 through the second air pipe 20, preventing the air entering the air compressor 11 from carrying dust and impurities that clog the pipes and atomizing nozzles 44. Then the air compressor 11 compresses the air, and the compressed high-pressure air is injected into the air storage tank 2 through the first air pipe 18 for temporary storage. At the same time, the air pressure sensor 12 detects the air pressure in the air storage tank 2 in real time and converts the detected air pressure value into an electrical signal and sends it to the PLC controller in the dry fog box controller 17. If the air pressure sensor 12... If the detected air pressure value is higher than the preset high air pressure threshold of the PLC controller inside the dry fog box controller 17, the PLC controller inside the dry fog box controller 17 will control the air compressor 11 and the three-way reversing solenoid valve 19 to cut off the power to avoid the risk of explosion due to excessive air pressure in the air tank 2. As the high-pressure air in the air tank 2 is continuously released, the air pressure in the air tank 2 will decrease. If the air pressure in the air tank 2 is lower than the preset low air pressure threshold of the PLC controller inside the dry fog box controller 17, the PLC controller inside the dry fog box controller 17 will control the air compressor 11 and the three-way reversing solenoid valve 19 to be powered on again to continue to replenish the high-pressure air in the air tank 2. This cycle continues, so that the air tank 2 can be continuously supplied with high-pressure air.

[0044] When the normally closed solenoid valve 13 is energized, it will open, allowing the high-pressure air in the air tank 2 to enter the mixing cylinder 15 along the three-way pipe 14. After the micro water pump 104 starts, it draws water from the water tank 1 into the guide pipe 105, and then into the treatment cylinder 101. The water then passes through the multi-layer filter element 103 for purification. The multi-layer filter element 103 can trap impurities in the water, preventing them from clogging the pipes and atomizing nozzles 44, thus ensuring the dry fog dust suppression effect. Finally, the purified water is injected into the three-way pipe through the water pipe 106. 14. The liquid then flows into the mixing cylinder 15 and mixes thoroughly with the high-pressure air. Next, the high-pressure air in the mixing cylinder 15 carries the liquid into the four-way pipe 16, and is evenly distributed to the dry fog dust suppression mechanism 4 in the feeding section, the dry fog dust suppression mechanism 5 in the transfer section, and the dry fog dust suppression mechanism 6 in the discharging section. The high-pressure air carrying the liquid enters the distributor 42 through the first conveying pipe 41, and is then evenly distributed again into multiple second conveying pipes 43. Finally, the high-pressure air carrying the liquid is sprayed out at high speed from the atomizing nozzle 44, where the atomizing nozzle 44 releases the liquid through the atomizing resonance chamber. High-pressure air is used to generate high-frequency sound waves that highly atomize the water, converting the delivered high-pressure air and water into dry fog with a particle diameter of 5-10µm. This dry fog is then sprayed onto the dust suppression point of the bulk material stacking and loading machine according to the control instructions of the dry fog dust suppression equipment. Since each atomizing nozzle 44 provides a specific spray shape, flow rate, and coverage area, the uniformly and densely arranged atomizing nozzles 44 on all rubber positioning strips 45 form a "conical" fog wall, enveloping the dust at the bulk material stacking and loading machine's dust suppression point. The dry fog and dust... When particles come into contact with and collide with each other, the dust particles stick together, agglomerate and grow larger, and settle under their own gravity, thereby achieving the purpose of dust suppression. The dry fog dust suppression mechanism 5 in the transfer section uses the same principle to perform dust suppression operations at the dust suppression point at the connection between the chain plate conveyor and the telescopic belt conveyor in the bulk material stacking and loading integrated machine. The dry fog dust suppression mechanism 6 in the discharge section also uses the same principle to perform dust suppression operations at the dust suppression point at the side discharge point of the telescopic belt conveyor in the bulk material stacking and loading integrated machine, so as to avoid the problem of small particulate bulk materials scattering and causing waste and environmental pollution.

[0045] During this process, the liquid level sensor 21 detects the water level in the water tank 1 in real time and converts the water level value into an electrical signal, which is then transmitted to the PLC controller in the dry fog box controller 17. If the water level is lower than the preset water level threshold of the PLC controller in the dry fog box controller 17, the PLC controller in the dry fog box controller 17 controls the water replenishment solenoid valve 22 to open, so that the water replenishment pipeline connected to the water replenishment valve 22 replenishes water into the water tank 1, ensuring that the water tank 1 has sufficient water and ensuring that the dust suppression device has a continuous dry fog dust suppression effect. This allows the device to have a continuous and efficient dust suppression effect on the bulk material stacking and loading integrated machine, avoiding the problem of small particulate bulk materials being scattered, causing waste and environmental pollution, and improving the reliability of the dry fog dust suppression device.

[0046] When the dry fog dust suppression mechanism 4 in the feeding section, the dry fog dust suppression mechanism 5 in the transfer section, and the dry fog dust suppression mechanism 6 in the discharging section are in use, the dust concentration sensor 47 in each dry fog dust suppression structure detects the dust concentration at each dust suppression point inside the "conical" dry fog wall, and converts the dust concentration into an electrical signal, which is then fed back to the PLC controller in the dry fog box controller 17. The PLC controller in the dry fog box controller 17 controls the opening of the adjustable electric valve 71 in the first dust suction mechanism 7, the second dust suction mechanism 8, and the third dust suction mechanism 9 according to the feedback dust concentration. This is because the dust concentration is dispersed... The dust concentration at each dust suppression point of the integrated material stacking and loading machine is not constant, but the maximum suction power of the air pump 37 is fixed. To ensure the dust suppression effect at each point, the suction effects of the first suction mechanism 7, the second suction mechanism 8, and the third suction mechanism 9 need to be dynamically adjusted to avoid the emission of small particulate materials that pollute the environment and cause waste. Specifically, the higher the dust concentration value detected by the dust concentration sensor 47 in the feeding section dry fog dust suppression mechanism 4, the transfer section dry fog dust suppression mechanism 5, and the discharge section dry fog dust suppression mechanism 6, the higher the corresponding adjustable electric suction power will be. The larger the opening of valve 71, the smaller the opening of the adjustable electric valve 71. Then, the air pump 37 draws air from inside the filter box 31, creating a low-pressure zone. To maintain pressure balance, the filter box 31 draws in outside air through the first suction mechanism 7, the second suction mechanism 8, and the third suction mechanism 9. The outside air carries the loose, small particulate matter into the filter box 31 along the pipeline consisting of the dust collection hood 75, the second connecting pipe 74, the hollow block 73, the first connecting pipe 72, and the adjustable electric valve 71. Afterward, the loose, small particulate matter... The material is trapped by the sponge primary filter layer 23 and the multi-layer air filter element 35. The purified air passes through the three-way reversing solenoid valve 19 and the air compressor 11 and is injected into the air storage tank 2. After the three-way reversing solenoid valve 19 is de-energized, the air in the filter box 31 is directly discharged through the air pump 37, the second air pipe 20 and the other outlet of the three-way reversing solenoid valve 19. This enables the dry fog dust suppression device to absorb and filter small particulate materials that have escaped, avoiding the problem of small particulate materials drifting and causing waste and environmental pollution. This improves the dust suppression effect and reliability of the dry fog dust suppression device.

[0047] When the bulk material stacking and loading machine is used to stack or load bulk materials that are easily perishable when exposed to water (such as cement clinker, grain, etc.), the air pump 37 is directly started by the PLC controller in the dry fog box controller 17. The air pump 37 works in conjunction with the dust purification mechanism 3, the first dust suction mechanism 7, the second dust suction mechanism 8, and the third dust suction mechanism 9 to collect small particles of bulk material floating at the dust suppression point of the bulk material stacking and loading machine. The water treatment mechanism 10, the dry fog dust suppression mechanism 4 in the feeding section, the dry fog dust suppression mechanism 5 in the transfer section, and the dry fog dust suppression mechanism 6 in the discharge section do not work, so as to avoid moisture damage to the bulk materials that are easily perishable when exposed to water. This can effectively improve the adaptability of the dry fog dust suppression device to the characteristics of bulk materials. Even when facing bulk materials that are easily perishable when exposed to water, the device has a highly efficient and stable dust suppression effect, which improves the safety of bulk material transportation and the reliability of the device.
