Technical Field

[0001] The 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 the construction of mining projects, dust pollution causes extremely serious harm. The flying dust not only poses a direct threat to the health of construction workers, but long-term exposure may cause pneumoconiosis and other diseases. It also causes a sharp deterioration in the surrounding air quality, affecting the normal life of nearby residents.

[0003] However, there are many problems with the current mine spray dust suppression equipment on the market. On the one hand, the particle size adjustment function has obvious defects. The mine operating environment is complex, and the size and properties of dust particles generated in different areas vary greatly. The ideal spray dust suppression equipment should be able to flexibly and accurately adjust the droplet size according to the actual situation of the dust particles to achieve the best dust suppression effect, but the droplet size of most existing equipment is either fixed or the adjustable range is very limited.

[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 control mechanism. The control ring in the control mechanism cooperates with the transmission gear and the drive gear. The drive motor drives the drive gear to rotate, and the drive gear drives the control ring to rotate through the docking tooth. The control ring drives the docking gear to rotate through the docking tooth 2, and then the docking bolt moves 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 collaborative working mechanism. The spray mechanism includes nozzle assembly 1 and nozzle assembly 2, which are alternately distributed. When the regulating ring rotates, it can synchronously drive nozzle assembly 1 and nozzle assembly 2 to work. By rotating the regulating ring, the control block openings of nozzle assembly 1 and nozzle assembly 2 can be changed at the same time, 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. Under the action of a specific curved groove, the docking bolt of nozzle assembly 2 can further adjust the control block opening 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 capabilities.

[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, airflows of different intensities can be flexibly matched. 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.

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

[0041] By adopting the above technical solution, a spray mechanism 314 is arranged inside the installation groove 3113 between the limiting grooves, and the spray mechanism 314 includes a nozzle assembly 1 3141 and a nozzle assembly 2 3142, which are respectively arranged inside the limiting grooves and are alternately distributed. The regulating ring 313 is meshed and connected with the docking gears (such as docking gear 1 314144 and docking gear 2 31424) in the spray mechanism 314 through the docking gear 2 3132 inside it. When the regulating ring 313 rotates, it will drive the components in 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 to the inside of 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 located at the top of the curved groove 1 314111 and is provided with an annular groove 314112 connected with 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] By adopting the above technical solution, a curved groove 1 314111 is provided near the top of the outer wall of the water supply pipe 1 31411. The design of the curved groove 1 314111 allows the docking bolt 1 314143 to slide inside it, thereby controlling the up and down movement of the rotating sleeve 1 31414. The stopper 314113 is designed to limit the movement range of the docking bolt 1 314143 and guide the docking bolt 1 314143 to change the movement direction at a specific position. When the regulating ring 313 rotates, the docking bolt 1 314143 is driven to slide in the curved groove 1 314111 through the interaction between the docking tooth 2 3132 and the docking gear 1 314144. The movement of the docking bolt 1 314143 will further drive the rotating sleeve 1 31414 and the collar 31415 to move upward, and the docking block 31416 on the top of the collar 31415 squeezes the control block 31417 to control the size of its opening.

[0044] The top of the water supply pipe 31411 is fixedly connected to an extension pipe 31412, the top of the extension pipe 31412 is provided with a fixed head 31413, the fixed head 31413 is slidably connected to a control block 31417 inside, the bottom of the control block 31417 is penetrated with a connecting groove 314171, the outer wall of the water supply pipe 31411 is rotatably connected to a 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 inside, and one end of the spring 314142 is connected to a sliding connection with the inner wall of the placement groove 314141 A docking bolt 314143 is provided, one end of which extends into the curved groove 314111 and the two are slidably connected. A docking gear 314144 meshing with the docking tooth 3132 is provided near the bottom of the outer wall of the rotating sleeve 31414. A ring 31415 slidably connected to the outer wall of the extension tube 31412 is rotatably connected to the top of the rotating sleeve 31414. A docking block 31416 is fixedly connected to the top of the ring 31415 at a position corresponding to the connecting groove 314171. The top of the docking block 31416 extends into 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, the rotating sleeve 1 31414 can rotate around the water supply pipe 1 31411. This design enables the rotating sleeve 1 31414 to drive the components thereon to move together, thereby achieving the adjustment of the spray particle size. When the rotating sleeve 1 31414 rotates, the docking bolt 1 314143 will slide in the curved groove 1 314111, and change the moving direction or distance due to the restriction of the shape of the curved groove 1 314111. A docking gear 1 314144 is arranged near the bottom of the outer wall of the rotating sleeve 1 31414. The docking gear 1 314144 is meshed and connected with the docking tooth 2 3132 inside the regulating ring 313. When the regulating ring 313 rotates, it will drive the docking tooth 2 3132 to move, and then the docking gear 1 314144 and the rotating sleeve 1 31414 rotate through the meshing action.

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

[0047] By adopting the above technical solution, the special shape of the curved groove 2 314211 limits the moving path of the docking bolt 2 31423, so that it can move according to the predetermined trajectory, thereby controlling the size of the spray particle size. The rotation of the rotating sleeve 2 31422 will drive the docking bolt 2 31423 inside it to move in the curved groove 2 314211, thereby achieving the adjustment of the spray particle size. The components set on the top of the rotating sleeve 2 31422 and the water supply pipe 2 31421 are the same as the nozzle assembly 1 3141. This design makes the nozzle assembly 2 3142 and the nozzle assembly 1 3141 consistent in structure and function, and can adjust the spray particle size synchronously, thereby improving the overall performance and stability of the equipment.

[0048] A ventilation slot 1 3112 is provided on the outer wall of the mounting plate 311 between the water supply slots 3111, a ventilation slot 2 321 is provided on the outer wall of the fixed plate 32 corresponding to the position of the ventilation slot 1 3112, a water supply pipe 322 is provided on the side of the fixed plate 32 away from the mounting plate 311, and the airflow generated by the fan 21 inside the air duct 2 is controllable, and the airflow reaches the nozzle assembly 1 3141 and the nozzle assembly 2 3142 through the ventilation slot 2 321 and the ventilation slot 1 3112, a fan 21 is provided inside the air duct 2, and a push rod 11 is hinged at 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 technical solution, the fan 21 generates a controllable airflow when working, which not only helps the diffusion and sedimentation of the droplets, but also can be guided to the nozzle assembly through the ventilation slot 1 3112 and the ventilation slot 2 321 to enhance the spray effect. A push rod 11 is hinged at the bottom of the other end of the wind tube 2, and the other end of the push rod 11 is hinged to the main body 1. This design allows the wind tube 2 to be adjusted at a certain angle relative to the main body 1, thereby optimizing the spray direction of the airflow and the spray coverage range. The hinged mode of the push rod 11 ensures the stability and flexibility of the wind tube 2 during the adjustment process.

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

[0051] In the 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 the 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 a number of nozzle assemblies one 3141 and nozzle assembly two 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 regulating ring 313 to rotate through the docking gear one 3131. The rotation of the outermost circle of the regulating ring 313 will drive the next regulating ring 313 to rotate through the transmission gear 316, and the kinetic energy transmission of the transmission gear 316 will cause all the regulating 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 will be driven to move. Due to the limitation 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 will drive 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 mesh with the docking tooth 2 3132. When the ring 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, the control block 31417 will move by squeezing. The opening size between the control blocks 31417 is controlled by controlling the upward movement height of the docking block 31416. The cross-sectional area of ​​the liquid flowing through is controlled by controlling the opening degree 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 314143 passes through the curved groove 314111 and enters the annular groove 314112, the opening between the stopper 314113 in the nozzle assembly 3141 is opened to the maximum. When the spray is of large particle size, the rotating sleeve 31414 drives the docking bolt 314143 to continue to rotate counterclockwise for nearly one circle and contact the inclined surface of the stopper 314113. The docking bolt 314143 will move into the mounting groove 314141 due to the guidance of the inclined surface, so as to jump over the stopper 314113. If the rotating sleeve 31414 rotates clockwise, it will be blocked by the stopper 314113 and then fall along the curved groove 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 ring 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 regulating ring 313 is needed to synchronously adjust the particle size of 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 limitation of the annular 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 water passes through. The smaller the opening, the finer the particle size of the liquid after atomization. In this way, 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 wind tube 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 opening between the control blocks 31417 is small, the high-speed airflow can be matched to achieve ultra-fine atomization. When the opening between the control blocks 31417 is large, the 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 atomization particle size adjustment. 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. The spray mechanism 314 includes alternately distributed nozzle assembly 1 3141 and nozzle assembly 2 3142. When the regulating ring 313 rotates, it can drive the two to work synchronously, so that the opening of the control block 31417 changes at the same time, and the spray particle size is uniformly adjusted. When different particle size water mist is required, the docking bolt 2 31423 of the nozzle assembly 2 3142 can further adjust the opening of the control block 31417 on the basis of the nozzle assembly 1 3141 under the action of the curved groove 2 314211, so as to achieve different particle size combinations, meet the diversified dust reduction needs, and enhance the dust reduction effect.

[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 the low-speed airflow, prolongs the residence time of the water mist in the air, increases the chance of contact with dust, and improves the dust reduction capability in all directions.

[0062] Advantage 4: Reliability and stability. The meshing transmission of the regulating ring 313, the transmission gear 316, and the driving gear 3122, as well as the matching design of the docking bolt and the curved groove, make the entire adjustment process smooth and reliable. The higher design of the docking gear 1 314144 ensures that the rotating sleeve 1 31414 will not be disengaged from the docking gear 2 3132 when it moves upward, ensuring stable cooperation of various components of the equipment during operation, reducing the probability of failure, ensuring long-term stable operation of the equipment, and reducing maintenance costs.
