Abstract
Description
Technical Field
[0001] This invention relates to the field of dust removal technology in fully mechanized coal mining faces, specifically to a synchronous spraying system on both sides of a guide trough. Background Technology
[0002] The guide chute is a specialized component installed behind the hydraulic support in a fully mechanized coal mining face. Its core function is to guide the coal and gangue generated during support relocation to slide orderly into the goaf. It also provides a certain degree of dust containment, preventing coal and gangue from rolling down and damaging equipment or affecting operational safety. Spraying is used for dust suppression because the hydraulic support generates a large amount of dust during relocation, lowering, and raising operations. This dust not only escapes from the upper and lower ends of the guide chute and drifts with the wind to the downwind working area, but also re-entrains dust that falls into the guide chute as it slides into the goaf. High concentrations of dust can seriously harm the respiratory health of workers and may even cause dust explosions. It also affects the normal operation of equipment and visibility during on-site work. The water mist formed by spraying effectively captures and condenses dust, inhibiting its spread and thus improving the underground working environment.
[0003] Existing spray devices have a fixed and singular spray pattern, which cannot be adaptively adjusted according to the dynamic changes in underground dust concentration. When the dust concentration exceeds the standard, the existing spray intensity and coverage are often insufficient to effectively suppress it. When the dust concentration has reached the standard, the device continues to spray, resulting in the ineffective consumption of water and electricity, and uneven dust suppression effect, making it difficult to achieve precise and efficient dust control. Summary of the Invention

[0014] Furthermore, the heat exchange mechanism includes a shell-and-tube heat exchanger, a cold water inlet pipe, a filter, and a water supply pipe. The outlet at the bottom of the shell-and-tube heat exchanger is connected to the confluence end of the water supply pipe. The cold water inlet pipe is installed on the top left side of the shell-and-tube heat exchanger. The filter is installed on the top of the cold water inlet pipe, and the water supply pipe is installed on the top of the filter.
[0015] Furthermore, the heat exchange mechanism also includes a hot water inlet pipe, a hot water outlet pipe, and two support plates. The hot water inlet pipe is installed on the top middle side of the shell-and-tube heat exchanger, and the hot water outlet pipe is installed on the top right side of the shell-and-tube heat exchanger. Both support plates are installed at the bottom of the shell-and-tube heat exchanger, and the bottom ends of both support plates are installed at the top of the mounting plate.
[0016] Furthermore, the atomizing mechanism includes a secondary atomizing chamber, a negative pressure dust removal nozzle, and a flow guide. The secondary atomizing chamber is installed between the inner walls of both sides of the angle adjustment bracket via a movable frame. The negative pressure dust removal nozzle is inserted into the middle of one end of the secondary atomizing chamber and connected to the spray branch pipe. The flow guide is installed in the middle of the other end of the secondary atomizing chamber.
[0017] Furthermore, the atomizing mechanism also includes a one-way valve and an air delivery mechanism. The one-way valve is disposed on the spray branch pipe, and the air delivery mechanism is installed through the outer wall of the secondary atomizing chamber.
[0018] Furthermore, the gas delivery mechanism includes a split pipe, multiple airflow nozzles, an airflow branch pipe, and an airflow regulating valve. The multiple airflow nozzles are all installed inside the split pipe, and the ends of the multiple airflow nozzles away from the split pipe penetrate the outer wall of the secondary atomization chamber. The airflow branch pipe is installed at the bottom end of the split pipe, and the other end of the airflow branch pipe is connected to the gas delivery pipeline. The airflow regulating valve is disposed on the airflow branch pipe.
[0019] Furthermore, the fixing frame and the angle adjustment bracket are both welded to the main body of the guide trough, the gas pipeline and the water pipeline both adopt a Y-shaped diversion structure, and the explosion-proof high-pressure air pump, water pressure regulating valve, dust concentration sensor and wind speed and direction monitor are all electrically connected to the intelligent control box.

[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] (1) This invention achieves real-time monitoring and dynamic response of dust concentration and airflow status in the well through the coordinated operation of dust concentration sensor, wind speed and direction monitor, intelligent control box, electromagnetic control valve and water pressure regulating valve. When the dust concentration exceeds the standard, the intelligent control box can drive the water pressure regulating valve to increase the spray intensity and the electromagnetic control valve to quickly open the spray branch. When the dust concentration reaches the standard, the electromagnetic control valve is controlled to close and the water pressure regulating valve is turned back. This solves the problem of the existing spray device having a fixed and single mode and being unable to adapt and adjust, avoids the ineffective consumption of water resources and electricity, and achieves precise dust reduction on demand.
[0024] (2) This invention achieves purification and precise temperature control of spray water through the coordinated operation of components such as shell-and-tube heat exchanger, cold water inlet pipe, filter and water supply pipe. The water source connected to the water supply pipe is filtered to remove impurities, and the filtered cold water enters the shell-and-tube heat exchanger through the cold water inlet pipe. The residual heat from the mine introduced from the hot water inlet pipe releases heat in the heat exchanger to exchange heat with the flowing cold water. This not only improves the condensation effect of water mist and dust, but also adapts to the harsh working environment of low-temperature mines.
[0025] (3) The present invention utilizes the coordinated operation of components such as a secondary atomization chamber, a negative pressure dust removal nozzle, a one-way valve, an air supply mechanism, and a flow guide hood. The negative pressure dust removal nozzle initially atomizes the water flow and sends it into the secondary atomization chamber. In the air supply mechanism, the annular diversion pipe sprays high-pressure airflow evenly into the chamber through multiple airflow nozzles, forming a strong shear mixing effect with the water mist, thereby further refining the droplet size. The flow guide hood then directional and regulates the atomized mist flow, ultimately forming a fine water mist with a wide coverage and strong capture ability, significantly improving the agglomeration efficiency of fine particulate dust and achieving precise dust removal without dead angles on both sides of the guide trough.

Detailed Implementation
[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0038] As attached Figure 1 To be continued Figure 8 As shown:
[0039] Example 1:
[0040] The present invention provides a dual-sided synchronous spraying system for a gangue guide trough, comprising a gangue guide trough body 1 and a mounting plate 2, wherein the gangue guide trough body 1 is used to guide the orderly sliding of coal gangue;
[0041] Sensing mechanism 3 is installed on one side of the top of mounting plate 2;
[0042] The sensing mechanism 3 includes a storage box 31, a sealed door 32, two partitions 33, multiple dust concentration sensors 34, multiple wind speed and direction monitors 35, and an intelligent control box 36. The storage box 31 is installed on the top of the mounting plate 2. The sealed door 32 is installed on the outer wall of the storage box 31 by a hinge. The two partitions 33 are installed between the inner walls on both sides of the storage box 31. The multiple dust concentration sensors 34 and the multiple wind speed and direction monitors 35 are respectively placed on the top of the two partitions 33. The intelligent control box 36 is installed in the middle of one end of the storage box 31 and has a built-in adaptive control algorithm.
[0043] Heat exchange mechanism 4 is installed on the other side of the top of mounting plate 2;
[0044] Multiple angle adjustment brackets 5 are respectively installed on the outer walls of both sides of the guide trough body 1, and are evenly distributed along the length direction of the guide trough body 1.
[0045] Multiple atomizing mechanisms 6 are installed inside multiple angle-adjustable brackets 5;
[0046] The atomizing mechanism 6 includes a spray branch pipe 63 and an electromagnetic control valve 64. The spray branch pipe 63 is connected to the water supply pipe 7, and the electromagnetic control valve 64 is installed on the spray branch pipe 63 and has a quick on / off function.
[0047] The water supply pipe 7 is installed between multiple atomizing mechanisms 6 and heat exchange mechanisms 4. Two water pressure regulating valves 8 are provided on the lower side of the outer wall of the water supply pipe 7.
[0048] Multiple fixing brackets 9 are installed on both outer walls of the main body 1 of the guide trough. The multiple fixing brackets 9 are all connected to the water conveying pipe 7. The multiple fixing brackets 9 are interspersed with the gas conveying pipe 10. An explosion-proof high-pressure air pump 11 is installed at the confluence end of the gas conveying pipe 10.
[0049] Both the fixed frame 9 and the angle adjustment bracket 5 are welded to the main body 1 of the guide trough. The welded connection ensures the stability of the installation of the fixed frame 9 and the angle adjustment bracket 5, prevents the components from loosening in the underground vibration environment, and provides a reliable installation foundation for the gas pipeline 10, water pipeline 7 and atomizing mechanism 6, ensuring the long-term stable operation of the system. Both the gas pipeline 10 and the water pipeline 7 adopt a Y-shaped diversion structure. The Y-shaped structure can realize the uniform diversion of air and water flow, ensuring that the atomizing mechanism 6 on both sides of the guide trough can obtain an equal and stable supply of air / water, ensuring the synchronous spraying effect on both sides, and avoiding the problem of uneven dust reduction caused by insufficient power supply on one side. The explosion-proof high-pressure air pump 11, water pressure regulating valve 8, dust concentration sensor 34 and wind speed and direction monitor 35 are all electrically connected to the intelligent control box 36, so that the intelligent control box 36 can receive the monitoring data (dust concentration, airflow status) of the sensor in real time and send control commands to the execution components.
[0050] Working principle: During use, the storage box 31 is mainly used to store spare dust concentration sensors 34, wind speed and direction monitors 35, and other items. In actual operation, the dust concentration sensors 34 and wind speed and direction monitors 35 need to be removed from the storage box 31. The dust concentration sensors 34 are installed in the core dust-escape zones on both sides of the main body 1 of the wastewater guide chute. The dust concentration sensors 34 monitor the dust concentration on both sides of the main body 1 of the wastewater guide chute in real time. The wind speed and direction monitors 35 are installed at the corresponding positions of the surrounding airflow monitoring points. The system accurately captures data on changes in underground airflow direction and speed, enabling real-time monitoring and dynamic response to underground dust concentration and airflow conditions. Both signals are stably transmitted to the intelligent control box 36 via explosion-proof cables. The intelligent control box 36 compares the real-time collected data with preset thresholds. If it detects excessive dust on one or both sides, or a sudden change in wind direction causing dust accumulation on the non-operating side, it immediately sends commands to the corresponding water pressure regulating valve 8 and solenoid control valve 64. This increases water pressure and spray intensity to enhance the spray effect. Simultaneously, it can adjust the settings according to... The water pressure is independently adjusted based on the difference in dust concentration on both sides to ensure more thorough spray coverage in high-concentration areas. If the dust concentration drops to the acceptable range, the intelligent control box 36 instructs the equipment to switch to a down-pressure mode, reducing water pressure and spray frequency to decrease water and electricity consumption. Simultaneously, the intelligent control box 36 links the explosion-proof high-pressure air pump 11, working in conjunction with the Y-shaped split-structure air supply pipe 10 and water supply pipe 7 to achieve synchronous and independently controllable air and water supply on both sides. The water supply pipe 7 is stably secured by multiple fixing brackets 9 welded to the outer walls on both sides of the guide trough body 1. When the water it delivers flows through the spray branch pipe 63, the intelligent control box 36 controls the electromagnetic control valve 64 to achieve precise on / off of the spray branch. The water pressure regulating valve 8 simultaneously completes the dynamic adjustment of the spray intensity. At the same time, multiple atomizing mechanisms 6 are installed on both sides of the guide trough body 1 through the angle adjustment bracket 5, which can flexibly adjust the spray angle. This completely solves the problem of the existing spray device having a fixed and single mode and being unable to adapt and adjust. It avoids the ineffective consumption of water resources and electricity, achieves precise and on-demand dust reduction, and achieves precision and energy saving in dust control.
[0051] Example 2:
[0052] This embodiment is basically the same as the previous embodiment, except that the heat exchange mechanism 4 includes a shell-and-tube heat exchanger 41, a cold water inlet pipe 42, a filter 43, and a water supply pipe 44. The outlet at the bottom of the shell-and-tube heat exchanger 41 is connected to the confluence end of the water supply pipe 7. The cold water inlet pipe 42 is installed on the top left side of the shell-and-tube heat exchanger 41. The filter 43 is installed on the top of the cold water inlet pipe 42. The water supply pipe 44 is installed on the top of the filter 43.
[0053] The heat exchange mechanism 4 also includes a hot water inlet pipe 45, a hot water outlet pipe 46, and two support plates 47. The hot water inlet pipe 45 is installed on the top middle side of the shell-and-tube heat exchanger 41, the hot water outlet pipe 46 is installed on the top right side of the shell-and-tube heat exchanger 41, and the two support plates 47 are both installed at the bottom of the shell-and-tube heat exchanger 41, and the bottom of the two support plates 47 are both installed at the top of the mounting plate 2.
[0054] Temperature sensors are installed at both the inlet and outlet of the shell-and-tube heat exchanger 41 to monitor the temperature of the spray water in real time. The temperature sensors feed the water temperature data back to the intelligent control box 36, providing a basis for water temperature regulation and ensuring that the spray water is stably preheated to the optimal condensation temperature of 30-40℃. This ensures that the heat exchange effect is precise and controllable. In addition, the shell-and-tube heat exchanger 41 is equipped with a polyurethane insulation layer to reduce the heat loss of the water flow after preheating inside the shell-and-tube heat exchanger 41, maintain water temperature stability, and avoid the impact of rapid temperature drop on the condensation efficiency of water mist and dust. At the same time, it is suitable for low-temperature mine environments and ensures the long-term efficient operation of the heat exchange mechanism 4.
[0055] Working principle: During use, the cold water supplied by the water supply pipe 44 first passes through the filter 43 to filter impurities, preventing blockage of subsequent pipelines and nozzles and ensuring stable system operation. The filtered cold water enters the shell-and-tube heat exchanger 41 through the cold water inlet pipe 42. At the same time, the high-temperature return oil pipeline of the downhole hydraulic system is connected to the hot water inlet pipe 45, allowing the high-temperature return oil to enter the shell-and-tube heat exchanger 41 through the hot water inlet pipe 45 to exchange heat with the cold water. Temperature sensors at the inlet and outlet of the shell-and-tube heat exchanger 41 monitor the water temperature in real time, ensuring that the spray water is preheated to the optimal condensation temperature of 30-40℃. Temperature, the low-temperature return oil after heat exchange flows back through the hot water outlet pipe 46, which can effectively utilize the residual heat of the return oil in the downhole hydraulic system. The preheated water is transported to each atomizing mechanism 6 through the water supply pipeline 7. With the linkage control of the explosion-proof high-pressure air pump 11, water pressure regulating valve 8, and electromagnetic control valve 64 by the intelligent control box 36, the spray can be adaptively adjusted. At the same time, the preheated hot water mist can improve the condensation efficiency with dust, which is especially suitable for low-temperature mining environment. This further ensures the dust suppression effect and the reliability of system operation, while extending the service life of pipelines and components, and ensuring the long-term reliable operation of the system.
[0056] Example 3:
[0057] This embodiment is basically the same as the previous embodiment, except that the atomizing mechanism 6 includes a secondary atomizing chamber 61, a negative pressure dust removal nozzle 62, and a flow guide 67. The secondary atomizing chamber 61 is installed between the inner walls of both sides of the angle adjustment bracket 5 through a movable frame. The negative pressure dust removal nozzle 62 is inserted into the middle of one end of the secondary atomizing chamber 61 and communicates with the spray branch pipe 63. The flow guide 67 is installed in the middle of the other end of the secondary atomizing chamber 61.
[0058] The atomizing mechanism 6 also includes a one-way valve 65 and an air delivery mechanism 66. The one-way valve 65 is disposed on the spray branch pipe 63, and the air delivery mechanism 66 is installed through the outer wall of the secondary atomizing chamber 61.
[0059] The gas delivery mechanism 66 includes a split pipe 661, multiple airflow nozzles 662, an airflow branch pipe 663, and an airflow regulating valve 664. The multiple airflow nozzles 662 are all installed inside the split pipe 661, and the ends of the multiple airflow nozzles 662 away from the split pipe 661 all penetrate the outer wall of the secondary atomization chamber 61. The airflow branch pipe 663 is installed at the bottom end of the split pipe 661, and the other end of the airflow branch pipe 663 is connected to the gas delivery pipeline 10. The airflow regulating valve 664 is provided on the airflow branch pipe 663.
[0060] The diverter 661 is designed as a ring structure, allowing multiple airflow nozzles 662 to be evenly arranged around the secondary atomization chamber 61. This ensures that the airflow can mix with the water mist in all directions without any dead angles, enhancing the shear atomization effect and improving the fineness of the droplets. The airflow regulating valve 664 and the electromagnetic control valve 64 are both electrically connected to the intelligent control box 36, enabling the intelligent control box 36 to precisely regulate the airflow through the airflow regulating valve 664 and control the on / off of the spray branch through the electromagnetic control valve 64. This achieves dynamic adaptation of spray intensity and spray start / stop, ensuring the accuracy of adaptive dust suppression. The secondary atomization chamber 61 is a cylindrical air-water mixing chamber with a stepped, gradually narrowing structure along the direction of water mist flow. The inner diameter of the inlet section is the largest, followed by the middle mixing section, and the inner diameter of the outlet section is the smallest. This structure enhances the shear force between the airflow and the water mist, promotes further droplet refinement, and improves dust agglomeration efficiency. It is a key structural guarantee for achieving secondary fine atomization.
[0061] Working principle: During use, water preheated by the shell-and-tube heat exchanger 41 is fed into the water supply pipeline 7, and then diverted to both sides of the guide trough body 1. It is then distributed to the negative pressure dust removal nozzles 62 via the spray branch pipes 63. The one-way valve 65 on the spray branch pipes 63 effectively prevents dust-laden water from flowing back into the pipeline and control components, ensuring system stability. The negative pressure dust removal nozzles 62 initially atomize the water and send it into the secondary atomization chamber 61. Simultaneously, the explosion-proof high-pressure air pump 11 starts, delivering high-pressure gas to the gas supply pipeline 10. The gas is then diverted through the airflow branch pipes 663 to the annular diversion pipe 661, and then evenly sprayed into the secondary atomization chamber 61 through multiple airflow nozzles 662. The gas mixes with the initially atomized water mist in the stepped, gradually narrowing chamber. A strong shear mixing effect is formed inside, achieving secondary fine atomization of droplet size; the intelligent control box 36, based on real-time data from the dust concentration sensor 34 and the wind speed and direction monitor 35, controls the airflow regulating valve 664 to adjust the airflow intensity and the water pressure regulating valve 8 to adjust the water supply pressure, and coordinates with the angle adjusting bracket 5 to adjust the installation angle of the secondary atomization chamber 61. Finally, the mist flow is oriented and regulated through the guide hood 67, forming a double-sided synchronous spray with wide coverage, fine droplet size, and strong capture ability, which significantly improves the agglomeration efficiency of fine particulate dust, and completely solves the problems of low dust reduction efficiency, uneven coverage, coarse spray size, and many dust reduction blind spots in existing devices, achieving precise dust removal without dead angles on both sides of the guide trough.
[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
