Description

TECHNICAL FIELD

[0002] A dust suppression device is a device used to reduce or eliminate the generation of dust and particulate matter. It can be applied in various industries such as construction, mining, chemical industry, food processing, etc. Common dust suppression devices include fans, dust collectors, sprayers, wet dust collectors, etc. These devices collect and process dust and particulate matter in various ways to reduce their impact on the environment and workers, protecting the environment and human health.

[0003] In the mining industry, dust suppression devices often use isolation walls combined with cloud dust suppression methods to achieve dust suppression effects. However, the use of isolation walls can only suppress dust in a fixed area, while mine loading and transporting equipment often has a large range of activities, resulting in an insufficient range of action for isolation walls to meet the needs of mine loading and transporting work. The cloud dust suppression method uses water to wet the mine material to reduce dust, but after dust suppression, particulate matter is often further discharged with water, causing pollution to water sources, and further processing of water sources also generates a large amount of industrial cost, which needs to be improved.

[0045] By adopting the vehicle-mounted assembly mode, the dust suppression device structures are combined with the transport equipment 1, which can move with the position adjustment of the transport equipment 1. The pneumatic dust suppression assembly 3 defines the range based on the airflow output mode to avoid the dust from drifting to the outside, and is provided with a vacuum adsorption device to increase the adsorption effect by creating a negative pressure space. The traditional type isolation wall has a fixed range of action, and the flexibility of the dust suppression range is improved. The water storage mechanism 4 and the mixing treatment mechanism 5 cooperate to generate the adhesive chemical dust suppressant, which is finally delivered to the atomizing and spraying mechanism 6 through the water pipe. The loading assembly 2 achieves the loading of the mine raw materials and the carrying and adjusting functions of the raw materials in the transport equipment 1, and is provided with the atomizing and spraying mechanism 6, so that the atomized adhesive chemical dust suppressant is sprayed by the operation of the atomizing and spraying mechanism 6 to suppress dust raising.

The dust raising sensor is arranged on the inner side of the carriage 102 to obtain the current dust concentration data.

[0048] Specifically, as shown in Figures 1 to 2 The pneumatic dust suppression assembly 3 includes a stand 301 fixedly installed on the upper surface of the moving table 203, and a canopy 302 fixedly installed at the top end of the stand 301.

[0049] During movement, the moving table 203 drives the canopy 302 through the stand 301 to adjust the position of the canopy 302. The inside of the canopy 302 is hollow, and the inside bottom is provided with a vacuum suction device. The negative pressure space is used to increase the suction effect, and the shunt air duct 303 is assembled. Through the operation of the drainage fan 304, air is introduced into the shunt air duct 303, and based on the trajectory of the shunt air duct 303, an air wall is output at the edge position of the bottom end of the canopy 302, thereby defining the range, cooperating with the transportation equipment 1, and meeting the mobile dust suppression demand based on the actual required range.

[0050] Specifically, as shown in Figure 3 The upper surface of the moving table 203 is rotatably connected with an adjusting seat 204 and a first hydraulic rod 205. The output end of the first hydraulic rod 205 is rotatably connected with the adjusting seat 204. The upper surface of the adjusting seat 204 is rotatably connected with a second hydraulic rod 207 and a first driving arm 206. The output end of the second hydraulic rod 207 is rotatably connected with the first driving arm 206. The surface of the first driving arm 206 is rotatably connected with a third hydraulic rod 209 and a second driving arm 208. The output end of the third hydraulic rod 209 is rotatably connected with the second driving arm 208.

[0051] The upper part of the moving table 203 is driven to rotate by the first hydraulic rod 205, and the first driving arm 206 is driven to rotate by the second hydraulic rod 207. The second driving arm 208 is driven to rotate by the third hydraulic rod 209.

[0052] Specifically, as shown in Figure 3 The surface of the second driving arm 208 is rotatably connected with a first arc-shaped frame 210, a second arc-shaped frame 211, and a fourth hydraulic rod 212. The output end of the fourth hydraulic rod 212 is rotatably connected with the first arc-shaped frame 210. A connecting shaft 213 is rotatably connected between the first arc-shaped frame 210 and the second arc-shaped frame 211. The surface of the second arc-shaped frame 211 is provided with a bucket 214 and a mounting plate 215.

[0053] The second driving arm 208 limits the rotation track of the first arc-shaped frame 210, the second arc-shaped frame 211 and the fourth hydraulic rod 212, and drives the first arc-shaped frame 210 to rotate through the extension and contraction of the fourth hydraulic rod 212, the first arc-shaped frame 210 drives the second arc-shaped frame 211 to rotate through the connecting shaft 213, and further drives the excavator 214 to overturn, thereby performing the excavation or mobilization work on the ore raw materials.

[0054] Specifically, as shown in Figure 6 The water storage mechanism 4 includes a first water storage tank 401 and a second water storage tank 402, the top of each of the first water storage tank 401 and the second water storage tank 402 is provided with a No. 1 three-way pipe 403 and a liquid level meter 404, one end of the No. 1 three-way pipe 403 is provided with an inlet pipe, the output end of the No. 1 three-way pipe 403 is provided with an outlet pipe 405, the surface of the outlet pipe 405 is provided with a liquid flow meter 406, the output end of the liquid flow meter 406 is provided with a water pump 407, the output ends of the water pump 407 are provided with a No. 2 three-way pipe 408, one end of the No. 2 three-way pipe 408 is provided with a flow pipe 409, and the first water storage tank 401, the second water storage tank 402 and the water pump 407 are fixedly installed on the upper surface of the ceiling 302.

[0055] In the water storage mechanism 4, the high polymer POL1 and the surfactant are respectively stored in the first water storage tank 401 and the second water storage tank 402, and the storage amount is fed back in real time through the liquid level meter 404, when the storage amount is insufficient, the high polymer is added through the inlet pipe and the No. 1 three-way pipe 403, when the mixing treatment work is performed, the water pump 407 is started, the outflow amount is recorded through the liquid flow meter 406, and is uniformly discharged through the No. 2 three-way pipe 408 and the flow pipe 409, according to the dust concentration obtained by testing, the dust suppression effect and the viscosity range required to be reached are determined, according to the change of the dust concentration, the addition amount of the high polymer is controlled. Higher dust concentration needs to add more high polymer to increase the viscosity of the chemical dust suppressant. Conversely, lower dust concentration needs to reduce the addition amount of the high polymer to ensure that the viscosity of the chemical dust suppressant is moderate.

[0056] Specifically, as shown in Figure 5 The mixing treatment mechanism 5 includes a treatment box 501, the treatment box 501 is fixedly installed on the upper surface of the ceiling 302, the upper surface of the treatment box 501 is fixedly installed with a box cover 502, the upper surface of the box cover 502 is provided with flow interfaces 503 at the front and rear ends, one group of the flow interfaces 503 is connected with the flow pipe 409, the output end of the other group of the flow interfaces 503 is assembled with a drainage pump, and a water pipe is assembled based on the drainage pump and is connected with the atomizing and spraying mechanism 6.

[0057] The liquid guided by the manifold 409 enters the inside of the processing box 501 through one set of through-flow interfaces 503, and after the processing inside the processing box 501 is completed, the generated adhesive chemical dust suppressant can be guided by the output end of another set of through-flow interfaces 503 and the drainage pump assembled thereby, and then sent to the atomizing and spraying mechanism 6 through the water pipe.

[0058] Specifically, as shown in Figure 7 The inside of the processing box 501 is rotatably connected with a first driving shaft 504 and a second driving shaft 505, which are symmetrically distributed between the first driving shaft 504 and the second driving shaft 505, and the outer surfaces of the first driving shaft 504 and the second driving shaft 505 are circumferentially and equidistantly mounted with stirring blades 506. The outer surfaces of the first driving shaft 504 and the second driving shaft 505 are respectively fixedly mounted with a driving gear 507 and a linkage gear 508, which are engaged with each other. The rear end of the driving gear 507 is provided with a linkage wheel 509, and the side surface of the processing box 501 is provided with a driving motor 510. The output end of the driving motor 510 is provided with a driving wheel 511, and the outer surfaces of the driving wheel 511 and the linkage wheel 509 are drivingly connected with a belt 512.

[0059] The processing flow inside the processing box 501 is specifically that the driving motor 510 drives the driving wheel 511 to rotate, and the belt 512 drives the linkage wheel 509 to rotate, which drives the driving gear 507 to rotate, and the driving gear 507 drives the linkage gear 508 to rotate, so that the first driving shaft 504 and the second driving shaft 505 rotate in opposite directions. At this time, the stirring blades 506 also rotate, achieving the mixing and processing effect of the high polymer POL1 and the surfactant, generating the adhesive chemical dust suppressant. In addition, the rotation parameters of the stirring blades 506 can be adjusted according to the actual dust concentration data and the like. The purpose of adjusting the rotation parameters of the stirring blades inside the processing box 501 is to improve the adaptability to different dust concentrations. One method is to adjust the rotation speed and stirring time of the stirring blades. For higher dust concentration, the rotation speed and stirring time can be increased to enhance the stirring effect and ensure that the chemical dust suppressant is fully mixed with the dust. For lower dust concentration, the rotation speed and stirring time can be appropriately reduced to avoid excessive consumption of energy and resources.

[0060] Specifically, as shown in Figure 9 The atomizing and spraying mechanism 6 includes a lower housing 601 and an upper housing 602. The lower housing 601 is fixedly connected with the mounting plate 215. The outer surface of the upper housing 602 is provided with an air inlet interface 603 and a water inlet interface 604. The surface of the air inlet interface 603 is provided with a dustproof net, and the water inlet interface 604 is connected with the water pipe.

[0061] The atomizing spray mechanism 6 is based on the lower housing 601 and the upper housing 602 as the main structure, and introduces air and adhesive chemical dust suppressant through the air inlet 603 and the water inlet 604.

[0062] Specifically, such as Figure 9 As shown, a reaction chamber 607 is installed inside the lower housing 601. An air inlet pipe 605 and a water inlet pipe 606 are installed at the input end of the reaction chamber 607. The air inlet pipe 605 and the water inlet pipe 606 are connected to the air inlet interface 603 and the water inlet interface 604, respectively. An ultrasonic generator 608 is installed at the output end of the reaction chamber 607. An exhaust fan 609 is installed inside the lower housing 601. Exhaust ports 610 are equidistantly opened on both sides of the outer surfaces of the lower housing 601 and the upper housing 602.

[0063] Adhesive chemical dust suppressant and air enter the reaction chamber 607 through the water inlet pipe 606 and the air inlet pipe 605. After being atomized by the ultrasonic generator 608, they are discharged from the exhaust port 610 by the exhaust fan 609. The position of the atomizing spray mechanism 6 moves with the mounting plate 215, thereby achieving a further dust suppression effect within the small working range of raw material handling and adjustment.

[0064] Working principle:

[0065] By adopting the vehicle-mounted assembly mode, the dust suppression device is combined with the transportation equipment 1 and can move with the position adjustment of the transportation equipment 1. The pneumatic dust suppression assembly 3 defines the range based on the air output mode to avoid the dust from drifting to the outside. The vacuum adsorption device is arranged to generate a negative pressure space to increase the adsorption effect. The traditional type isolation wall has a fixed action range, and the flexibility of the dust suppression range is improved. The water storage mechanism 4 and the mixing treatment mechanism 5 cooperate to generate the adhesive type chemical dust suppressant, which is finally delivered to the atomizing spraying mechanism 6 through the water pipe. The loading assembly 2 achieves the loading of the mine raw materials and the carrying and adjusting functions of the raw materials in the transportation equipment 1. The atomizing spraying mechanism 6 is carried to spray the atomized adhesive type chemical dust suppressant to suppress the dust and further achieve the dust suppression effect in the small work range of the raw material carrying and adjusting. The dust suppression is realized by generating a solidified film on the dust surface through the atomized adhesive type chemical dust suppressant, which avoids the water pollution caused by the cloud dust. In the transportation equipment 1, the transportation vehicle body 101 loads the carriage 102, and the carriage 102 realizes the assembly function of the ore raw materials. The loading assembly 2 drives the travel frame 202 through the operation of the electric drive sliding rail 201, and then adjusts the position of the moving table 203. The moving table 203 drives the ceiling 302 through the column 301 during the movement to drive the ceiling 302 to adjust the position. The ceiling 302 is hollow inside, and the inside bottom is provided with a vacuum adsorption device to generate a negative pressure space to increase the adsorption effect. The assembly shunt air duct 303 is assembled, and the air is introduced into the shunt air duct 303 through the operation of the drainage fan 304. The air is output as an air wall at the bottom edge position of the ceiling 302 based on the track of the shunt air duct 303, so as to define the range and meet the mobile dust suppression demand based on the actual required range in cooperation with the transportation equipment 1. The upper part of the moving table 203 drives the adjusting seat 204 to rotate through the extension and contraction of the first hydraulic rod 205, drives the first drive arm 206 to rotate through the extension and contraction of the second hydraulic rod 207, drives the second drive arm 208 to rotate through the extension and contraction of the third hydraulic rod 209, and the second drive arm 208 limits the rotation track of the first arc-shaped frame 210, the second arc-shaped frame 211 and the fourth hydraulic rod 212, and drives the first arc-shaped frame 210 to rotate through the extension and contraction of the fourth hydraulic rod 212. The first arc-shaped frame 210 drives the second arc-shaped frame 211 to rotate through the connecting shaft 213, and further drives the excavator 214 to overturn to perform the excavation or mobilization work on the ore raw materials. In the water storage mechanism 4, the first water storage tank 401 and the second water storage tank 402 store the polymer POL1 and the surfactant respectively. The storage amount is fed back in real time through the liquid level meter 404. When the storage amount is insufficient, the first three-way pipe 403 is added. When the mixing treatment work is performed, the water pump 407 is started to record the outflow amount through the liquid flow meter 406, and is uniformly discharged through the second three-way pipe 408 and the flow pipe 409.The liquid guided by the manifold 409 enters the inside of the processing box 501 through one set of through-flow interfaces 503, and after the processing inside the processing box 501 is completed, the generated adhesive chemical dust suppressant can be guided by the drainage pump assembled at the output end of the other set of through-flow interfaces 503, and sent to the atomizing and spraying mechanism 6 through the water pipe. The processing flow inside the processing box 501 is that the driving motor 510 drives the driving wheel 511 to rotate, and the belt 512 drives the linkage wheel 509 to rotate, which drives the driving gear 507 to rotate, and the driving gear 507 drives the linkage gear 508 to rotate, so that the first driving shaft 504 and the second driving shaft 505 rotate in opposite directions, and the stirring blade 506 also rotates at the same time, achieving the mixing and processing effect of the polymer POL1 and the surfactant, generating the adhesive chemical dust suppressant. The atomizing and spraying mechanism 6 is based on the lower shell 601 and the upper shell 602 to carry the main structure, and introduces air and adhesive chemical dust suppressant through the air inlet interface 603 and the water inlet interface 604. The adhesive chemical dust suppressant and air enter the reaction bin 607 through the water inlet pipe 606 and the air inlet pipe 605, and are atomized by the ultrasonic generator 608, and then are discharged from the air outlet 610 by the exhaust fan 609. The position of the atomizing and spraying mechanism 6 moves with the mounting plate 215, and further dust suppression effect is achieved in the small work range of raw material transportation and adjustment.
