Description

Technical Field

[0001] The present invention belongs to the technical field of dust prevention and control, and particularly relates to a separate roadway isolation and diversion dust removal system for a heading face. Background Art

[0002] During the coal mining process, a roadway tunneling machine is one of the commonly used equipment for tunneling and transporting coal in a roadway. However, when the tunneling machine works in the transportation and transfer section, a large amount of dust will be generated, especially during the unloading and transfer processes, where the dust concentration is extremely high. These dusts not only pose a serious threat to the health of the staff, but may also lead to equipment failures and safety hazards. Traditional dust removal methods usually adopt spray dust suppression or mechanical filtration, but these methods have problems such as low dust removal efficiency, large waste of water resources, and complex equipment maintenance. In addition, the ventilation system in the roadway is usually relatively simple, making it difficult to effectively control the spread of dust. Especially in the transfer section, dust is prone to accumulation, resulting in the deterioration of air quality. Existing ventilation systems often cannot flexibly adjust the air volume according to the actual working conditions, resulting in poor ventilation effects and unable to meet the health needs of the staff. Summary of the Invention

[0003] The purpose of the present invention is to provide a separate roadway isolation and diversion dust removal system for a heading face, which can reasonably organize the air flow, optimize the ventilation effect, and effectively ensure the air quality of the working environment.

[0004] To achieve the above purpose, the present invention provides a separate roadway isolation and diversion dust removal system for a heading face, including a roadway. An isolation plate is arranged in the roadway along the length direction of the roadway, and the roadway is divided into a fresh air area and a polluted air area. In the fresh air area, a tunneling machine and an integrated fresh air supply and air volume regulation system are arranged along the direction away from the isolation plate. The integrated fresh air supply and air volume regulation system is arranged at the rear end of the roadway, and a fresh air pipe is connected thereto. The tunneling machine is arranged at the front end of the roadway. A bridge-type transfer machine is connected to the rear end of the tunneling machine. A transport belt detachably connected to the tunneling machine is arranged below the bridge-type transfer machine. A dust-proof cover is connected to the overlapping position of the bridge-type transfer machine and the transport belt. An electromagnetic wet energy dust collector that moves synchronously with the transport belt is connected to the rear end of the transport belt. A wind collecting cover connected to the electromagnetic wet energy dust collector is arranged in the polluted air area.

[0005] As a further scheme of the present invention: The electromagnetic wet energy dust collector includes a dust collector body and a filter water tank connected to the bottom of the dust collector body. The outer shell of the dust collector body is a double-layer structure, with an electromagnetic coil embedded therein. An air inlet connected to the wind collecting cover is arranged at the bottom of the dust collector body, and an air outlet is arranged at the top. A swirl plate, a spray system, and a dehydration system are sequentially connected in the dust collector body from bottom to top. A liquid inlet pipe connected to the outside is arranged on the spray system. The filter water tank is connected to the spray system through a circulating water pipe.

[0006] As a further solution of the present invention: The spray system includes a spray ring I, an adjustable deflector vane, and a spray ring II, which are arranged in sequence from bottom to top. The adjustable deflector vane is controlled by a servo motor to adjust the angle. Part of the liquid required by the spray ring I comes from the liquid inlet pipe, and part comes from the circulating water pipe. The liquid required by the spray ring II comes from the biostatic agent provided by the liquid inlet pipe.

[0007] As a further solution of the present invention: The proportion of the biostatic agent is: 0.007% of secondary alkyl sulfonate + 0.3% of alkyl polyglycoside + 99.693% of deionized water.

[0008] As a further solution of the present invention: The dehydration system is composed of multi-layer nested baffle plates, adopting a variable pitch structure. The pitch is larger near the air inlet and smaller near the air outlet.

[0009] As a further solution of the present invention: Inside the filter box, there are a sewage area, a filtration area, and a purified water area in sequence. The bottom end of the dust collector is connected to the sewage area. A water level sensor and a water pump are provided in the purified water area, and the water pump is connected to the circulating water pipe.

[0010] As a further solution of the present invention: Inside the filter box, there are a sewage area, a filtration area, and a purified water area in sequence. The bottom end of the dust collector is connected to the sewage area. A water level sensor and a water pump are provided in the purified water area, and the water pump is connected to the circulating water pipe.

[0011] As a further solution of the present invention: The isolation board extends from before the driver's position of the roadheader to behind the electromagnetic wet energy dust collector, including fixed isolation boards fixed at the frontmost and rearmost ends. Between the two fixed isolation boards, there are multiple groups of movable isolation boards with a push-pull structure. The movable isolation boards move forward or backward with the roadheader through the slide rails on the top of the roadway.

[0012] As a further solution of the present invention: The slide rails are divided into two slide rails A and B. The movable isolation board moves on the two slide rails A and B and has an overlapping part. As the overlapping area changes, the extension and contraction of the isolation board are realized.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) Flexible air volume adjustment: The multi-stage air ducts of the fresh air supply and air volume adjustment integrated system are composed of air ducts with different diameters, and the diameter size and quantity can be set as required. The multi-stage air ducts are connected by a diversion device made of stretchable flexible material. By controlling the stretching of the diversion device through the telescopic device, the air supply cross-sectional area can be conveniently adjusted, and thus the air volume can be flexibly regulated.

[0015] (2) High dust removal and cleaning efficiency: The electromagnetic wet energy dust collector uses a new formula of biological dust suppressant to improve the dust removal efficiency. It utilizes the Lorentz force generated by the electromagnetic coil and electromagnetic vibration to achieve efficient dust cleaning, reducing the accumulation of dust on the inner wall of the electromagnetic wet energy dust collector. The unique variable pitch multi-layer nested baffle design of the dehydration system also helps to efficiently separate water droplets and purify the air.

[0016] (3) Controllable rotating airflow: The adjustable guide vane precisely adjusts the angle through the servo motor, and can generate rotating airflows of different intensities according to different environments, enhancing the adaptability of the system to complex working conditions.

[0017] (4) Recycling of water resources: The filtration water tank can filter the sewage falling from the electromagnetic wet energy dust collector. Controlled by the water level sensor, the filtered purified water is recycled to the spray system to achieve the recycling of water resources, saving energy and protecting the environment.

[0018] (5) Excellent effect of dust suppressant: The new biological dust suppressant used in the electromagnetic wet energy dust collector has an experimentally determined optimal ratio of 0.007% secondary alkyl sulfonate + 0.3% alkyl polyglycoside + 99.693% deionized water. Under this ratio, the surface tension of the biological dust suppressant is 26.472 mN / m, the contact angle is 30.56°, and the dust sedimentation time is 44 s. The dust suppression effect is significantly better than other conditions.

[0019] (6) Clear zoning and high efficiency: The design combines fixed partition plates and movable partition plates. The movable partition plate is a push-pull structure, which can extend and shorten with the forward and backward movement of the roadheader to adapt to the changes in the roadway space under different working conditions. The partition plate clearly divides the roadway into two parts, forming a fresh air area and a polluted air area, which helps to reasonably organize the air flow and optimize the ventilation effect. The electromagnetic wet energy dust collector is connected to the polluted air area through the air collecting hood, and can effectively collect the gas in the polluted air area, purify it and then discharge it, effectively ensuring the air quality of the working environment.

Specific embodiments

[0034] The present invention will be further described below through embodiments.

[0035] As Figure 1 And Figure 2As shown in the figure, a split roadway isolation and diversion dust removal system for a tunneling face includes a roadway 6. An isolation plate 3 is provided in the roadway 6 along the length direction of the roadway 6, and the roadway 6 is divided into a fresh air area and a polluted air area, which helps to reasonably organize the air flow and optimize the ventilation effect. In the fresh air area, a roadheader 1 and an integrated fresh air supply and air volume regulation system 4 are provided along the direction away from the isolation plate 3. The integrated fresh air supply and air volume regulation system 4 is arranged at the rear end of the roadway 6, and a fresh air pipe 2 is connected thereto. The roadheader 1 is arranged at the front end of the roadway 6. A bridge-type transfer machine 11 is connected to the rear end of the roadheader 1. A conveyor belt 9 detachably connected to the roadheader 1 is arranged below the bridge-type transfer machine 11. A dust-proof cover 8 is connected to the overlapping position of the bridge-type transfer machine 11 and the conveyor belt 9 to prevent dust from being generated during the falling process of coal blocks. The rear end of the conveyor belt 9 is connected to an electromagnetic wet energy dust collector 5 that moves synchronously with the conveyor belt 9; a wind collecting hood 7 connected to the electromagnetic wet energy dust collector 5 is arranged in the polluted air area.

[0036] Further, as Figure 9 shown, the electromagnetic wet energy dust collector 5 includes a dust collector body and a filter water tank 57 connected to the bottom of the dust collector body. The outer shell of the dust collector body is a double-layer structure, and an electromagnetic coil 56 is embedded therein. An air inlet 51 connected to the wind collecting hood 7 is provided at the bottom of the dust collector body, and an air outlet 55 is provided at the top. A swirl plate 52 (as Figure 13 shown), a spray system 53, and a dehydration system 54 are sequentially connected in the dust collector body from bottom to top. A liquid inlet pipe 59 connected to the outside is provided on the spray system 53. The filter water tank 57 is connected to the spray system 53 through a circulating water pipe 58.

[0037] Utilize the Lorentz force and electromagnetic vibration generated by the energized electromagnetic coil 56 to achieve efficient dust cleaning; specifically, after the electromagnetic coil 56 is energized, dust will be affected by the Lorentz force when moving with the air flow. The magnetic field generated after the dust particles are charged will also cause a certain degree of electromagnetic vibration on the metal outer wall of the electromagnetic wet energy dust collector 5. This vibration can make the dust particles attached to the inner wall of the electromagnetic wet energy dust collector 5 more likely to fall off under the action of external forces, and then be carried away by water flow or air flow, thereby reducing the accumulation of dust on the inner wall of the electromagnetic wet energy dust collector 5.

[0038] Further, as Figure 9 and Figure 10 shown, the spray system 53 includes a spray ring Ⅰ 531, adjustable guide vanes 532, and a spray ring Ⅱ 533 arranged in sequence from bottom to top. The adjustable guide vanes 532 are controlled by a servo motor to adjust the angle. Part of the liquid required by the spray ring Ⅰ 531 comes from the liquid inlet pipe 59, and part comes from the circulating water pipe 58. The liquid required by the spray ring Ⅱ 533 comes from the biocidal inhibitor provided by the liquid inlet pipe 59. The adjustable guide vanes 532 precisely adjust the blade angle through a servo motor, so that different intensities of rotating air flows can be generated according to different environments.

[0039] Further, the proportion of the biological bacteriostatic agent is: 0.007% of secondary alkyl sulfonate (SAS-60) + 0.3% of alkyl polyglucoside (APG0810) + 99.693% of deionized water. The surface tension of the biological dust suppressant obtained with this formula is 26.472 mN / m, the contact angle is 30.56°, and the dust settlement time is 44 s. Compared with other conditions, the biological dust suppressant obtained with this proportion has the best effect.

[0040] Further, as Figure 12 shown, the dehydration system 54 is composed of multi-layer nested baffle plates, adopting a variable pitch structure. The pitch is larger near the air inlet 51 and smaller near the air outlet 55.

[0041] Further, as Figure 11 shown, inside the filter box are successively a sewage area 571, a filtration area 572, and a purified water area 573. The bottom end of the dust collector is connected to the sewage area 571. A water level sensor and a water pump 574 are provided in the purified water area 573, and the water pump 574 is connected to the circulating water pipe 58.

[0042] The sewage falling from the electromagnetic wet energy dust collector 5 enters the sewage area 571, is filtered through the filtration area 572 and then enters the purified water area 573. A water level sensor is installed inside the purified water area 573. When the water level reaches a certain level, the purified water is lifted to the spray system 53 through the water pump 574 via the circulating water pipe 58, realizing the recycling of water.

[0043] Further, as Figures 6 to 8 shown, the fresh air supply and air volume regulation integrated system 4 includes a fan 41 and a multi-stage air duct 42 connected to the fan 41. The multi-stage air duct 42 includes several air ducts with different diameters and sleeved with each other. As shown in the figure, the multi-stage air duct 42 includes a primary air duct 421, a secondary air duct 422, and a tertiary air duct 423, and the diameter and quantity of the air ducts can be set according to actual conditions. Adjacent air ducts are connected by a diversion device 425 to facilitate the flow of gas. The diversion device 425 is made of a stretchable flexible material. A control ring 426 is sleeved outside the diversion device 425, and a telescopic device 424 connected to the control ring 426 is embedded in the inner wall of the air duct.

[0044] When the dust concentration monitor carried by the operator detects that the dust concentration reaches a certain amount, it transmits a signal to the fresh air supply and air volume regulation integrated system 4. The fresh air supply and air volume regulation integrated system 4 will automatically adjust the air volume. The telescopic device 424 controls the control ring 426 connected to it to stretch the diversion device 425 until it is embedded in the inner wall of the next-stage air duct 421. At this time, the air supply cross-sectional area of the multi-stage air duct 42 becomes larger. When the wind speed remains unchanged, the air supply volume becomes larger. On the contrary, the effect of reducing the air supply volume can be achieved.

[0045] Further, asFigures 1 to 5 As shown in the figure, the isolation plate 3 extends from before the driver's position of the roadheader 1 to after the electromagnetic wet energy dust collector 5, including fixed isolation plates 31 fixed at the frontmost and rearmost ends. Between the two fixed isolation plates 31, there are multiple groups of movable isolation plates 32 with a push-pull structure. The movable isolation plates 32 move forward or backward with the roadheader 1 along the slide rails 10 on the top of the roadway 6.

[0046] The fixed isolation plate 31 includes a front fixed isolation plate 311 and a rear fixed isolation plate 312. The front fixed isolation plate 311 is fixed on the right side of the driver's position of the roadheader 1, and the rear fixed isolation plate 312 is fixed on the right side of the rear end of the conveyor belt 9.

[0047] Furthermore, the slide rails 10 are divided into two slide rails 10, namely A and B. The movable isolation plates 32 move on the two slide rails 10 of A and B and have an overlapping part. With the change of the overlapping area, the extension and contraction of the isolation plate 3 are realized.

[0048] Two working states of isolation Figure 4 As shown in the figure, when the roadheader 1 is closely connected to the conveyor belt 9 and moves forward synchronously, the movable isolation plates 32 are in a contracted state. Figure 5 As shown in the figure, when the roadheader 1 is separated from the conveyor belt 9 and only the roadheader 1 continues to move forward, the state of the movable isolation plates 32 changes significantly and quickly unfolds. Only a certain number of the telescopic states of the movable isolation plates 32 are shown in the figure. In actual situation, several movable isolation plates 32 are used in combination.

[0049] The operation steps when implementing the present invention are as follows:

[0050] Step 1: When the underground mining operation starts, the roadheader 1 starts to work, and the integrated fresh air supply and air volume regulation system 4 starts to supply fresh air to the transfer point and adjusts the air volume according to the changes in the environment. The density sensor in the roadway 6 monitors the dust concentration in the roadway 6 in real time. When the dust concentration is relatively high, the primary air duct 423 can be used to ensure that there is enough fresh air blowing into the transfer point during the operation to ensure the life and health of the staff.

[0051] Step 2: When the roadheader 1 is working, the fresh air duct 2 presses the dust into the air collecting hood 7. The air collecting hood 7 is connected to the air inlet 51 of the electromagnetic wet energy dust collector 5. The dust-containing gas enters the interior of the electromagnetic wet energy dust collector 5 through the air inlet 51. The dust-containing gas enters the spray system 53 through the swirl plate 52, first passes through the spray ring I 531, then through the adjustable guide vane 532, and the spray ring II 533. Part of the liquid sprayed by the spray ring I 531 comes from the outside and part comes from the filter water tank 57. The liquid sprayed by the spray ring II 533 is a biological dust suppressant from the outside. Since the air volume is large at this time, the angle of the adjustable guide vane 532 is between 60° and 90°. After passing through the spray system 53, a large amount of dust is separated from the gas, and the wettability of the treated gas is enhanced. Then it enters the dehydration system 54. The variable pitch nested structure of the dehydration system 54 throws the dust and droplets attached to the gas towards the inner wall of the electromagnetic wet energy dust collector 5. At this time, the dust-containing gas is cleaned and discharged outside the roadway 6 through the air outlet 55.

[0052] Step 3: When the electromagnetic wet energy dust collector 5 is working, the Lorentz force and electromagnetic vibration generated by the energized electromagnetic coil 56 reduce the dust accumulation on the inner wall of the dust collector. Furthermore, the dust-containing liquid enters the filter water tank. After passing through the filtration area 572, the liquid is purified. When the set water level is reached, it can be recycled for the spray ring I 531.

[0053] Step 4: At the same time, the conveyor belt 9 remains stationary in place to transport the coal blocks that fall from the bridge conveyor 11. Since the dust-proof cover 8 is installed on the conveyor 11 to collect the dust generated when the coal blocks fall, the dust-proof cover 8 moves forward together with the roadheader 1. Starting from the initial state, as the roadheader 1 advances step by step, the distance between the conveyor belt 9 and the roadheader 1 becomes larger and larger. Therefore, the movable partition 32 installed on its side continuously unfolds until the overlapping area of the movable partition 32 gradually becomes zero when the roadheader 1 advances to the maximum distance. At this time, it reaches the fully extended state (as Figure 5 shown). The movable partition 32 perfectly adapts to the dynamic changes in the space of the roadway 6 during the operation of the roadheader 1, further optimizing the ventilation partition in the roadway 6 and providing strong support for efficient operation.
