Description

Technical Field

[0001] The present invention relates to the technical field of mine environmental protection construction, in particular to a pollution control spray dust reduction device for mine engineering construction. Background Art

[0002] During mining construction, dust pollution poses a serious threat. The flying dust not only poses a direct threat to the health of construction workers, with long-term exposure potentially causing various diseases such as pneumoconiosis, but also significantly deteriorates surrounding air quality, impacting the lives of nearby residents.

[0003] However, current mine spray dust suppression equipment on the market presents numerous problems. For one thing, the particle size adjustment function suffers from significant deficiencies. Mining operating environments are complex, and the size and properties of dust particles generated in different areas vary significantly. Ideally, spray dust suppression equipment should be able to flexibly and precisely adjust the droplet size based on the actual dust particle situation to achieve optimal dust reduction. However, the droplet size of most existing equipment is either fixed or has a very limited adjustment range. Faced with the complex and diverse nature of mine dust, it is unable to effectively bind to and settle dust particles, resulting in low dust reduction efficiency and difficulty meeting actual needs.

[0015] The beneficial effects of the pollution control spray dust reduction equipment for mining engineering construction of the present invention are as follows:

[0016] 1. Accurate and flexible particle size adjustment function. The equipment is equipped with a regulating mechanism. The regulating ring in the regulating mechanism cooperates with the transmission gear and the drive gear. The driving motor drives the drive gear to rotate, and the drive gear drives the regulating ring to rotate through the docking gear. The regulating ring drives the docking gear to rotate through the docking gear, thereby moving the docking bolt along the curved groove. This design enables the opening size of the control block in the nozzle assembly to be continuously and steplessly adjusted, thereby accurately controlling the cross-sectional area through which the liquid flows, and realizing flexible adjustment of the atomized particle size. It can meet the complex and diverse dust particle size suppression needs in different areas of the mine, and greatly improve the dust reduction efficiency.

[0017] 2. Efficient multi-stage atomization and coordinated working mechanism. The spray mechanism includes nozzle assembly 1 and nozzle assembly 2, which are arranged alternately. When the control ring rotates, it can synchronously drive nozzle assembly 1 and nozzle assembly 2 to work. By rotating the control ring, the openings of the control blocks of nozzle assembly 1 and nozzle assembly 2 can be changed simultaneously, realizing synchronous adjustment of the spray particle size. When water mist of different particle sizes is required, nozzle assembly 1 and nozzle assembly 2 can be adjusted separately. The docking bolt of nozzle assembly 2, under the action of a specific curved groove, can further adjust the opening of the control block on the basis of nozzle assembly 1, realizing a combination of different water mist particle sizes, achieving efficient multi-stage atomization effect, and enhancing dust reduction capability.

[0018] 3. Airflow assists in optimizing the dust reduction effect. The fan inside the air duct generates airflow, which passes through ventilation slot 2 and ventilation slot 1 to reach nozzle assembly 1 and spray assembly 2. According to the size of the control block opening, it can flexibly match airflows of different intensities. When the openings between the control blocks are small, high-speed airflow can be matched to achieve ultra-fine atomization, making it easier for water mist to combine with fine dust and settle. When the openings between the control blocks are large, low-speed airflow is adapted to extend the residence time of water mist in the air, increase the chance of contact with dust, and comprehensively improve the dust reduction effect.

[0038] The atomizing device 3 includes a regulating mechanism 31 and a fixed plate 32. The fixed plate 32 is fixedly connected to the end of the air duct 2. The fixed plate 32 includes a mounting plate 311 fixedly connected to the fixed plate 32. A water supply groove 3111 is provided on the side of the mounting plate 311 close to the fixed plate 32.

[0039] The mounting plate 311 is provided with a plurality of mounting grooves 3113 arranged concentrically and nested on one side of the mounting plate 311. An adjusting ring 313 is rotatably connected to the mounting groove 3113. A docking tooth 1 3131 is provided on the outside of the adjusting ring 313. A limiting groove is provided on one side of the adjusting ring 313. A docking tooth 2 3132 is provided inside the limiting groove. A transmission gear 316 that meshes with the docking tooth 1 3131 is rotatably connected to the mounting groove 3113 near the adjusting ring 313. A fixing plate 315 is fixedly connected to the outer wall of the mounting plate 311 near the transmission gear 316. A fixing shell 312 is symmetrically provided on the outer wall of the mounting plate 311. A driving gear 3122 that meshes with the docking tooth 1 3131 is rotatably connected to the fixing shell 312. A driving motor 3121 is fixedly connected to the outer wall of the fixing shell 312 near the driving gear 3122. The output end of the driving motor 3121 passes through the fixing shell 312 and is fixedly connected to the driving gear 3122.

[0040] A limiting groove is formed through one side of the regulating ring 313 , and a second docking tooth 3132 is provided inside the limiting groove. A spray mechanism 314 is provided between the limiting grooves inside the mounting groove 3113 .

[0041] By adopting the above technical solution, a spray mechanism 314 is installed within the mounting groove 3113, located between the retaining grooves. The spray mechanism 314 includes a first nozzle assembly 3141 and a second nozzle assembly 3142, which are respectively arranged within the retaining grooves and arranged in an alternating manner. The control ring 313 engages with the docking gears (such as docking gear 1 314144 and docking gear 2 31424) in the spray mechanism 314 through its internal docking gear 3132. When the control ring 313 rotates, it drives the components of the spray mechanism 314 to move, thereby adjusting the particle size and flow rate of the spray.

[0042] The spray mechanism 314 includes a nozzle assembly 1 3141 and a nozzle assembly 2 3142. The nozzle assembly 1 3141 and the nozzle assembly 2 3142 are respectively arranged inside the limiting groove and are alternately distributed. The nozzle assembly 1 3141 includes a water supply pipe 1 31411 fixedly installed inside the mounting groove 3113. The bottom end of the water supply pipe 1 31411 passes through the mounting plate 311 and extends into the water supply groove 3111. A curved groove 1 314111 is provided on the outer wall of the water supply pipe 1 31411 near the top. The water supply pipe 1 31411 is provided with an annular groove 314112 connected to the curved groove 1 314111 at the top of the curved groove 1 314111. A stopper 314113 is provided inside the annular groove 314112 near the curved groove 1 314111. The stopper 314113 is provided with an inclined surface on the side away from the curved groove 1 314111.

[0043] Through the above-described technical solution, a curved groove 314111 is formed on the outer wall of water supply pipe 1 31411, near the top. This groove 314111 allows docking pin 1 314143 to slide within it, thereby controlling the up and down movement of rotating sleeve 1 31414. A stopper 314113 is designed to limit the range of movement of docking pin 1 314143 and guide it to change direction when in a specific position. When the control ring 313 rotates, the interaction between docking gear 2 3132 and docking gear 1 314144 drives docking pin 1 314143 to slide within the curved groove 314111. The movement of docking pin 1 314143 further drives rotating sleeve 1 31414 and collar 31415 upward. The docking block 31416 at the top of collar 31415 compresses the control block 31417, controlling the opening size.

[0044] The top of the water supply pipe 31411 is fixedly connected to the extension pipe 31412, the top of the extension pipe 31412 is provided with a fixed head 31413, the fixed head 31413 is internally slidably connected to the control block 31417, the bottom of the control block 31417 is penetrated by a connecting groove 314171, the outer wall of the water supply pipe 31411 is rotatably connected to the rotating sleeve 31414, the outer wall of the rotating sleeve 31414 is provided with a placement groove 314141 near the curved groove 314111, the placement groove 314141 is provided with a spring 314142, one end of the spring 314142 is connected to a sliding connection with the inner wall of the placement groove 314141 The docking bolt 314143 is provided, one end of the docking bolt 314143 extends into the interior of the curved groove 314111 and the two are slidably connected. A docking gear 314144 is provided near the bottom of the outer wall of the rotating sleeve 31414, which is meshed with the docking tooth 2 3132. The top of the rotating sleeve 31414 is rotatably connected to a ring 31415 which is slidably connected to the outer wall of the extension tube 31412. The top of the ring 31415 is fixedly connected to a docking block 31416 at a position corresponding to the connecting groove 314171. The top of the docking block 31416 extends into the interior of the connecting groove 314171 and the two are slidably connected. The docking block 31416 has a narrow upper and wide lower structure.

[0045] By adopting the above technical solution, rotating sleeve 1 31414 is able to rotate around water supply pipe 1 31411. This design allows rotating sleeve 1 31414 to move the components on it, thereby adjusting the spray particle size. When rotating sleeve 1 31414 rotates, docking bolt 1 314143 slides within curved groove 1 314111, changing its direction or distance due to the shape of curved groove 1 314111. A docking gear 1 314144 is provided near the bottom of the outer wall of rotating sleeve 1 31414. This docking gear 1 314144 meshes with docking teeth 2 3132 within the control ring 313. When the control ring 313 rotates, it drives docking teeth 2 3132 to move, and this meshing action causes docking gear 1 314144 and rotating sleeve 1 31414 to rotate.

[0046] The second nozzle assembly 3142 includes a second water supply pipe 31421 fixedly installed inside the mounting groove 3113. The bottom end of the second water supply pipe 31421 passes through the mounting plate 311 and extends into the water supply groove 3111. An inverted "V"-shaped curved groove 314211 is provided on the outer wall of the second water supply pipe 31421 near the top. The outer wall of the second water supply pipe 31421 is rotatably connected to a second rotating sleeve 31422. A second docking bolt 31423 is provided inside the second rotating sleeve 31422 near the position of the second curved groove 314211. One end of the second docking bolt 31423 extends into the interior of the second curved groove 314211 and the two are slidably connected. A second docking gear 31424 is provided on the outer wall of the second rotating sleeve 31422 near the bottom, which engages with the second docking tooth 3132. The components provided on the top of the second rotating sleeve 31422 and the second water supply pipe 31421 are the same as those of the first nozzle assembly 3141.

[0047] By employing this technical solution, the unique shape of curved groove 2 314211 restricts the movement path of docking pin 2 31423, allowing it to move along a predetermined trajectory, thereby controlling the spray particle size. The rotation of rotating sleeve 2 31422 drives docking pin 2 31423 within it to move within curved groove 2 314211, thereby adjusting the spray particle size. The components mounted on the top of rotating sleeve 2 31422 and water supply pipe 2 31421 are identical to those of nozzle assembly 1 3141. This design ensures that nozzle assembly 2 3142 and nozzle assembly 1 3141 are structurally and functionally consistent, enabling simultaneous adjustment of the spray particle size and improving the overall performance and stability of the device.

[0048] A ventilation slot 1 3112 is provided through the outer wall of the mounting plate 311 between the water supply slot 3111, and a ventilation slot 2 321 is provided through the outer wall of the fixed plate 32 corresponding to the position of the ventilation slot 1 3112. A water supply pipe 3 322 is provided on the side of the fixed plate 32 away from the mounting plate 311. The airflow generated by the fan 21 inside the air duct 2 is controllable, and the airflow passes through the ventilation slot 2 321 and the ventilation slot 1 3112 to reach the nozzle assembly 1 3141 and the nozzle assembly 2 3142. A fan 21 is provided inside the air duct 2, and a push rod 11 is hinged to the bottom of the other end of the air duct 2, and the other end of the push rod 11 is hinged to the main body 1.

[0049] By adopting the above-mentioned technical solution, fan 21 generates a controllable airflow when in operation. This airflow not only aids in the diffusion and sedimentation of the mist droplets but also guides them to the nozzle assembly through ventilation slots 1 3112 and 2 321, enhancing the spray effect. A push rod 11 is hingedly connected to the bottom of the other end of the air cylinder 2. The other end of push rod 11 is hinged to the main body 1. This design allows the air cylinder 2 to be adjusted at a certain angle relative to the main body 1, thereby optimizing the airflow direction and spray coverage. The hinged connection of push rod 11 ensures the stability and flexibility of the air cylinder 2 during adjustment.

[0050] The working principle and usage process of the embodiment of the present invention are as follows:

[0051] In a normal state, the docking bolt 1 314143 is located at the lowest point in the curved groove 1 314111 , and the docking bolt 2 31423 is located at the lowest point in the curved groove 2 314211 . At this time, the control block 31417 is in a closed state.

[0052] When in use, water is provided to the equipment through the water supply pipe three 322, and then the water supply pipe three 322 transports the water to the water supply tank 3111, and the water is provided to several nozzle assemblies 1 3141 and nozzle assembly 2 3142 through the water supply tank 3111. When spraying, the drive motor 3121 is first started, and the drive motor 3121 will drive the drive gear 3122 to rotate. The drive gear 3122 will drive the outermost circle of the control ring 313 to rotate through the docking gear 1 3131. The rotation of the outermost circle of the control ring 313 will drive the next control ring 313 to rotate through the transmission gear 316, and the kinetic energy transmission of the transmission gear 316 causes all the control rings 313 to rotate.

[0053] When the regulating ring 313 rotates, it drives the second docking gear 3132 located inside the limiting groove to move, and the second docking gear 3132 drives the first docking gear 314144 and the second docking gear 31424 to rotate (with Figure 7 、 8For example, the docking gear 1 314144 and the docking gear 2 31424 rotate counterclockwise. When the docking gear 1 314144 rotates, the docking bolt 1 314143 is driven to move. Due to the restriction of the curved groove 1 314111, the docking bolt 1 314143 can only move upward along the path of the curved groove 1 314111. The movement of the docking bolt 1 314143 drives the rotating sleeve 1 31414 and the collar 31415 to move upward. 44 is relatively high, so when the rotating sleeve 1 31414 moves upward, it will not be out of engagement with the docking tooth 2 3132. When the collar 31415 moves upward, it will drive the docking block 31416 to move upward and squeeze the connecting groove 314171. The docking block 31416 is narrow at the top and wide at the bottom, so as the docking block 31416 moves upward, it will squeeze the control block 31417 to move. By controlling the upward movement height of the docking block 31416, the size of the opening between the control blocks 31417 can be controlled. The cross-sectional area of ​​the liquid flowing through is controlled by controlling the degree of the opening between the control blocks 31417. The smaller the opening, the finer the particle size of the liquid after atomization. Conversely, the larger the opening, the larger the particle size. Thus, continuous and stepless atomization particle size adjustment can be achieved to meet the suppression requirements of different dust particle sizes. When the docking bolt 1 314143 passes through the curved groove 1 314111 and enters the annular groove 314112, the opening between the block 314113 in the nozzle assembly 1 3141 is opened to the maximum. When the spray is large-particle size, the rotating sleeve 1 31414 drives the docking bolt 1 314143 to continue to rotate counterclockwise for nearly one circle, and then it will contact the inclined surface of the stopper 314113. The docking bolt 1 314143 will be guided by the inclined surface and move into the placement groove 314141, so that it can jump over the stopper 314113. If the rotating sleeve 1 31414 rotates clockwise, it will be blocked by the stopper 314113 and then fall along the curved groove 1 314111.

[0054] The rotation of docking gear 2 31424 will drive the water supply pipe 2 31421 to move, and the movement of water supply pipe 2 31421 will drive docking bolt 2 31423 to move. Due to the limitation of curved groove 2 314211, docking bolt 2 31423 can only rotate and move upward along curved groove 2 314211. The upward movement of docking bolt 2 31423 will drive the top component of sleeve 31415 to work like nozzle assembly 1 3141 through rotating sleeve 2 31422. When docking bolt 2 31423 moves to the highest point of curved groove 2 314211, control block 31417 is opened to the maximum. At this time, only the regulating ring 313 is needed to synchronously adjust the particle size of the spray of nozzle assembly 1 3141 and nozzle assembly 2 3142.

[0055] When water mist of different particle sizes is required, the control block 31417 in the nozzle assembly 1 3141 and the nozzle assembly 2 3142 is opened to the maximum, and then the regulating ring 313 continues to drive the docking gear 1 314144 and the docking gear 2 31424 to rotate. The docking gear 1 314144 will not be able to continue to open due to the restriction of the ring groove 314112, and the docking gear 2 31424 drives the docking bolt 2 31423 to continue to move. After the docking bolt 2 31423 passes the highest point of the curved groove 2 314211, it can continue to move downward for a distance. This descending distance can reduce the opening between the control blocks 31417 in the nozzle assembly 2 3142, thereby increasing the cross-sectional area when the water passes through. The smaller the opening, the finer the particle size of the liquid after atomization, so that the adjustment of different water mist particle sizes can be achieved.

[0056] When it is necessary to close the nozzle assembly 1 3141 and the nozzle assembly 2 3142, it is only necessary to control the control ring 313 to rotate in the opposite direction. When the control ring 313 rotates in the opposite direction, it will drive the docking gear 1 314144 and the docking gear 2 31424 to rotate in the opposite direction, thereby driving the docking bolt 1 314143 and the docking bolt 2 31423 to move in the opposite direction to close the control block 31417.

[0057] When the spray mechanism 314 is working, the fan 21 will generate airflow inside the air duct 2, and the size of the airflow is controllable. The airflow will pass through the ventilation slot 2 321 and the ventilation slot 1 3112 to the nozzle assembly 1 3141 and the nozzle assembly 2 3142, and the water mist will be moved by the airflow. When the openings between the control blocks 31417 are small, high-speed airflow can be matched to achieve ultra-fine atomization. When the openings between the control blocks 31417 are large, low-speed airflow is adapted to extend the residence time of the water mist.

[0058] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0059] Advantage 1: Precise particle size adjustment: the driving motor 3121 drives the driving gear 3122 to rotate, and drives the regulating ring 313 to rotate through the docking tooth 1 3131. The regulating ring 313 engages with the docking gear 1 314144 and the docking gear 2 31424 through the docking tooth 2 3132, so that the docking bolt 1 314143 and the docking bolt 2 31423 move along the curved groove 1 314111 and the curved groove 2 314211, thereby driving the control block 31417 to change the opening size, accurately adjusting the cross-sectional area through which the liquid flows, and realizing continuous and stepless adjustment of the atomized particle size. It can better adapt to the complex and diverse dust particles in different areas of the mine and significantly improve the dust reduction efficiency.

[0060] Advantage 2: Multi-stage atomization coordination. Spray mechanism 314 comprises alternating nozzle assemblies 1 3141 and 2 3142. Rotation of control ring 313 synchronizes both, causing the opening of control block 31417 to change simultaneously, uniformly adjusting the spray particle size. When different particle sizes are required, docking bolt 2 31423 of nozzle assembly 2 3142, coupled with curved groove 2 314211, further adjusts the opening of control block 31417 based on nozzle assembly 1 3141, achieving different particle size combinations, meeting diverse dust reduction needs and enhancing dust reduction effectiveness.

[0061] Advantage three: airflow assists efficiency enhancement. The fan 21 in the air duct 2 generates controllable airflow, which reaches the nozzle assembly 1 3141 and the nozzle assembly 2 3142 through the ventilation slot 2 321 and the ventilation slot 1 3112. When the opening between the control blocks 31417 is small, it matches the high-speed airflow to achieve ultra-fine atomization, making it easier to capture fine dust. When the opening is large, it adapts to low-speed airflow, prolongs the residence time of the water mist in the air, increases the chance of contact with dust, and comprehensively improves the dust reduction capability.

[0062] Advantage 4: Reliability and stability. The meshing transmission between the control ring 313, transmission gear 316, and drive gear 3122, as well as the coordinated design of the docking pin and the curved groove, ensures a smooth and reliable adjustment process. The higher design of docking gear 1 314144 ensures that the rotating sleeve 1 31414 does not disengage from docking gear 2 3132 when it moves upward. This ensures stable coordination between all components during operation, reduces the probability of failure, ensures long-term stable operation, and reduces maintenance costs.
