Description

Technical Field

[0001] The invention relates to the technical field of mineral mining, and in particular to underground mining equipment with a dust removal function. Background Art

[0002] During underground mining, a large amount of dust is generated due to processing and crushing, which poses potential hazards to the surrounding environment and human body, and must be removed. There are many types of dust with different properties. Generally speaking, the smaller the dust particle size, the harder it is to settle in the air and the harder it is to capture. With the flow of air, it causes long-term and large-scale pollution, and is easily inhaled into the deep respiratory tract with air, which is more harmful to the human body. In addition, dust can also reduce product quality and machine working accuracy, thereby affecting production and causing economic losses. For some combustible mining dust, there may even be explosion hazards.

[0003] Chinese patent publication number: CN110080761A, discloses a dust removal device and dust removal method for sidewall mining equipment. The bellows is fixed on the cantilever of the coal mining machine, and the air outlet of the bellows is flexibly connected to the transition section; one end of the transition section is flexibly connected to the air outlet of the bellows, and the other end is connected to the air suction port of the dust removal fan; the air outlet of the dust removal fan is connected to one end of the first unit wind tube; the first unit wind tube is hung on the wire rope of the first transport unit through a lifting ring, and the other end of the first unit wind tube is connected to one end of the standard unit wind tube through the wind tube connector, the standard unit wind tube is hung on the wire rope of the standard transport unit through the lifting ring, and the other end of the standard unit wind tube is connected to the next section of the standard unit wind tube through the wind tube connector, and so on; the telescopic wind tube is hung on the wire rope under the platform through the lifting ring, one end of the telescopic wind tube is connected to the last section of the standard unit wind tube, and the other end of the telescopic wind tube is connected to the dust collector air inlet duct.

[0004] The current underground dust removal technology usually installs ventilation equipment next to the mining equipment. On the one hand, the ventilation equipment and the mining equipment lack linkage control, resulting in untimely dust removal; on the other hand, separate equipment and channels need to be added, which makes the construction cumbersome. Summary of the invention

[0005] To this end, the present invention provides an underground mining equipment with a dust removal function to overcome the problem in the prior art that dust removal is performed by setting a ventilation device next to the mining equipment during underground mining, and the lack of linkage control between the ventilation device and the mining equipment leads to untimely dust removal.

[0006] To achieve the above object, the present invention provides an underground mining equipment with dust removal function, comprising:

[0007] A tunneling head, which is arranged at the front end of the mining equipment and is used for tunneling operations;

[0008] An adsorption unit, used to adsorb dust generated during excavation operations, comprising an adsorption module, wherein the adsorption unit determines a standard working mode of the adsorption module according to the humidity and temperature of the underground environment;

[0009] A spray unit, used for spraying the dust not adsorbed by the adsorption unit to prevent the dust from spreading;

[0010] A dust concentration detection device, used to detect the dust concentration in the environment after being adsorbed by the adsorption unit;

[0011] A control unit is respectively connected to the tunneling head, the adsorption unit, the spray unit, and the dust concentration detection device. The control unit determines whether to adjust the standard working mode of the adsorption module according to the tunneling speed of the tunneling head, and determines whether the working mode of the adsorption unit at startup is reasonable according to the data detected by the dust concentration detection device, and adjusts the working mode of the adsorption unit according to the corresponding determination results.

[0012] A traveling device, which is arranged at the bottom of the mining equipment and connected to the control unit, and is used to drive the mining equipment to travel underground;

[0013] An equipment body, which is arranged on the upper part of the traveling device, and the control unit is arranged inside the equipment body;

[0014] A support arm, which is arranged on the equipment body and is used to support and guide the tunneling head;

[0015] The spray unit comprises: a spray module arranged on the support arm, a water storage tank arranged on the equipment body, and a conveying channel is arranged between the spray module and the water storage tank;

[0016] The adsorption unit comprises: an adsorption module arranged between the spraying module and the tunneling head, and a dust storage box arranged on the equipment body, wherein the adsorption module and the dust storage box are connected via a dust channel.

[0017] Furthermore, the control unit starts the adsorption unit when the tunneling head is performing tunneling operations to adsorb dust generated during the tunneling operations. The control unit determines whether to adjust the standard working mode of the adsorption module according to the tunneling speed of the tunneling head.

[0018] Furthermore, the dust concentration detection device detects the dust concentration in the environment after being adsorbed by the adsorption unit. If the dust concentration in the environment does not meet the standard, the control unit adjusts the initial working mode of the adsorption module;

[0019] The initial working mode of the adsorption module is a working mode determined only by the tunneling speed of the tunneling head;

[0020] If the control unit does not adjust the standard working mode of the adsorption module due to the excavation speed of the excavation head, the standard working mode of the adsorption module is the initial working mode of the adsorption module;

[0021] If the control unit adjusts the standard working mode of the adsorption module due to the excavation speed of the excavation head, the adjusted working mode is the initial working mode of the adsorption module.

[0022] Furthermore, a dust concentration detection threshold is provided in the control unit, and the dust concentration detection device transmits the detected dust concentration to the control unit. If the detected dust concentration is greater than the dust concentration detection threshold, the control unit determines that the dust concentration in the environment does not meet the standard.

[0023] Furthermore, the initial working mode of the adsorption module is preset with an air suction volume of the first working mode of the adsorption module. If the control unit determines that the dust concentration in the environment does not meet the standard, the control unit adjusts the air suction volume of the first working mode of the adsorption module according to the difference between the detected dust concentration and the dust concentration detection threshold. The adjusted air suction volume is the regulated air suction volume.

[0024] Furthermore, the adsorption module is provided with a rated threshold value for air suction volume. If the regulated air suction volume is greater than the rated threshold value for air suction volume, the control unit controls the adsorption module to operate at the rated threshold value for air suction volume and controls the spray unit to start.

[0025] Furthermore, the control unit is provided with a tunneling speed interval.

[0026] If the excavation speed of the excavation head is within the excavation speed range, the control unit does not adjust the standard working mode of the adsorption module;

[0027] If the excavation speed of the excavation head is not within the excavation speed range, the control unit adjusts the standard working mode of the adsorption module.

[0028] Furthermore, the adsorption module is provided with a standard air suction volume.

[0029] If the standard working mode of the adsorption module is not adjusted, the standard suction volume is set to the suction volume of the first working mode;

[0030] If the standard working mode of the adsorption module is adjusted, the adjusted suction volume is the suction volume of the first working mode.

[0031] Furthermore, the value of the standard air suction volume is related to the humidity and temperature of the underground environment, and the value is inversely proportional to the humidity and directly proportional to the temperature.

[0032] Compared with the prior art, the beneficial effect of the present invention lies in that, by arranging an adsorption unit on the mining equipment to adsorb the dust generated during the excavation operation, and adjusting the working mode of the adsorption unit according to the excavation speed of the excavation head, the consistency of the mining operation and the dust removal operation is ensured, and the timeliness of the dust removal operation is enhanced. At the same time, by arranging a spray unit, the dust that has not been adsorbed is sprayed, thereby reducing the dust concentration in the underground environment.

[0033] Furthermore, under the same conditions, when the excavation speed is fast, more dust is generated, and when the excavation speed is slow, less dust is generated. By detecting the excavation speed of the excavation head and adjusting the working mode of the adsorption module according to the excavation speed, the consistency of the mining operation and the dust removal operation is ensured, the timeliness of the dust removal operation is enhanced, and the working mode of the adsorption module is made more reasonable through linkage adjustment.

[0034] Furthermore, by detecting the excavation speed of the tunneling head and adjusting the suction volume of the adsorption module according to the excavation speed, when the excavation speed difference is the same, the calculation compensation parameter for increasing the suction volume is greater than the calculation compensation parameter for reducing the suction volume, thereby ensuring that dust can be effectively adsorbed during the mining operation. At the same time, the suction volume is determined by the excavation speed, so that the suction volume is kept in a more appropriate range while meeting the suction requirements, thereby preventing energy waste caused by blindly using a larger suction volume.

[0035] Furthermore, by detecting the dust concentration in the environment after the adsorption unit completes adsorption, the dust concentration in the environment can be obtained in real time. In the case of excessive concentration, the working mode of the adsorption module is adjusted according to the dust concentration, thereby ensuring the control of the dust concentration in the mining environment and ensuring the effective adsorption of dust during the mining operation.

[0036] Furthermore, in the case where the operation of a single adsorption module cannot meet the dust removal requirements, liquid is sprayed through the spray unit to adsorb the remaining dust in the environment to ensure that the dust concentration in the underground environment is within a reasonable range.

[0037] Furthermore, under the same environment, the higher the temperature or the lower the humidity, the greater the amount of dust during the mining process. Therefore, by detecting the temperature and humidity of the mining environment and adjusting the value of the standard air suction volume, it is ensured that the dust can be effectively adsorbed during the mining operation.

[0048] The present invention provides an underground mining equipment with a dust removal function, comprising:

[0049] A tunneling head 1, which is arranged at the front end of the mining equipment and is used for tunneling operations;

[0050] The adsorption unit is used to adsorb dust generated during the excavation operation, and includes an adsorption module 61. The adsorption unit determines a standard working mode of the adsorption module according to the humidity and temperature of the underground environment;

[0051] A spray unit, used for spraying the dust not adsorbed by the adsorption unit to prevent the dust from spreading;

[0052] A dust concentration detection device 2, used to detect the dust concentration in the environment after being adsorbed by the adsorption unit;

[0053] A control unit is connected to the tunneling head 1, the adsorption unit, the spray unit, and the dust concentration detection device 2, respectively. The control unit determines whether to adjust the standard working mode of the adsorption module according to the tunneling speed of the tunneling head 1, and determines whether the working mode of the adsorption unit at startup is reasonable according to the data detected by the dust concentration detection device 2, and adjusts the working mode of the adsorption unit according to the corresponding determination results.

[0054] The present invention ensures the consistency of mining operation and dust removal operation and enhances the timeliness of dust removal operation by arranging an adsorption unit on the mining equipment for adsorbing dust generated during the tunneling operation and adjusting the working mode of the adsorption unit according to the tunneling speed of the tunneling head 1. At the same time, by arranging a spray unit, the dust that has not been completely adsorbed is sprayed to reduce the dust concentration in the underground environment.

[0055] A traveling device 3, which is arranged at the bottom of the mining equipment and connected to the control unit, and is used to drive the mining equipment to travel underground;

[0056] The device body 4 is arranged on the upper part of the traveling device 3, and the control unit is arranged inside the device body 4;

[0059] The adsorption unit includes: an adsorption module 61 disposed between the spraying module 71 and the tunneling head 1 , and a dust storage box 62 disposed on the equipment body 4 . The adsorption module 61 and the dust storage box 62 are connected via a dust channel 63 .

[0060] See also Figure 2-Figure 3 As shown, Figure 2 is a flow chart of the underground mining equipment with dust removal function in the embodiment, Figure 3 A flow chart for determining the air suction volume in the first working mode in the embodiment;

[0061] Specifically, the control unit starts the adsorption unit when the tunneling head is performing tunneling operations to adsorb dust generated during the tunneling operations. The control unit determines whether to adjust the standard working mode of the adsorption module according to the tunneling speed of the tunneling head.

[0062] Specifically, the control unit is provided with a tunneling speed interval.

[0063] If the excavation speed of the excavation head is within the excavation speed range, the control unit does not adjust the standard working mode of the adsorption module;

[0064] If the excavation speed of the excavation head is not within the excavation speed range, the control unit adjusts the standard working mode of the adsorption module.

[0065] The control unit is provided with a first excavation speed A1 and a second excavation speed A2, wherein A1<A2. The control unit obtains the excavation speed Aj of the excavation head.

[0066] If A1≤Aj≤A2, the control unit determines that the excavation speed of the excavation head is within the excavation speed range;

[0067] If Aj>A2 or Aj<A1, the control unit determines that the excavation speed of the excavation head is not within the excavation speed range.

[0068] In this embodiment, A1=9.3 m / d, A2=9.8 m / d.

[0069] Under the same conditions, when the excavation speed is fast, more dust is generated, and when the excavation speed is slow, less dust is generated. By determining the excavation speed of the excavation head and adjusting the working mode of the adsorption module according to the excavation speed, the consistency of the mining operation and the dust removal operation is ensured, the timeliness of the dust removal operation is enhanced, and the working mode of the adsorption module is made more reasonable through linkage adjustment.

[0070] Specifically, the adsorption module is provided with a standard air suction volume Bz,

[0071] If the standard working mode of the adsorption module is not adjusted, the standard suction volume Bz is set to the first working mode suction volume Bc;

[0072] If the standard working mode of the adsorption module is adjusted, the adjusted suction volume is the first working mode suction volume Bc.

[0073] If Aj>A2, then Bc=Bz+(Aj-A2)×C1, where C1 is the first calculation compensation parameter of the excavation speed difference to the air suction volume in the first working mode;

[0074] If Aj<A1, then Bc=Bz+(Aj-A1)×C2, where C2 is the second calculation compensation parameter of the excavation speed difference for the suction volume in the first working mode.

[0075] In this embodiment, C1 = 1.1 m 2 d / min, C2=0.8m 2 d / min.

[0076] The air suction volume in the first working mode is the air suction volume of the adsorption unit determined only by the excavation speed.

[0077] See also Figure 4 As shown, Figure 4 This is a flow chart of the working mode of the adsorption module according to the dust concentration in the embodiment;

[0078] Specifically, the dust concentration detection device detects the dust concentration in the environment after being adsorbed by the adsorption unit. If the dust concentration in the environment does not meet the standard, the control unit adjusts the initial working mode of the adsorption module;

[0079] The initial working mode of the adsorption module is a working mode determined only by the tunneling speed of the tunneling head;

[0080] If the control unit does not adjust the standard working mode of the adsorption module due to the excavation speed of the excavation head, the standard working mode of the adsorption module is the initial working mode of the adsorption module;

[0081] If the control unit adjusts the standard working mode of the adsorption module due to the excavation speed of the excavation head, the adjusted working mode is the initial working mode of the adsorption module.

[0082] By detecting the excavation speed of the tunneling head and adjusting the suction volume of the adsorption module according to the excavation speed, when the excavation speed difference is the same, the calculation compensation parameter for increasing the suction volume is greater than the calculation compensation parameter for reducing the suction volume, thereby ensuring that dust can be effectively adsorbed during the mining operation. At the same time, the suction volume is determined by the excavation speed, so that the suction volume is kept in a more appropriate range while meeting the suction requirements, thereby preventing energy waste caused by blindly using a larger suction volume.

[0083] Specifically, the control unit is provided with a dust concentration detection threshold Dz, and the dust concentration detection device transmits the detected dust concentration Dj to the control unit. If Dj≥Dz, the control unit determines that the dust concentration in the environment does not meet the standard. In this embodiment, Dz=6mg / m 3 .

[0084] See also Figure 5 As shown, Figure 5This is a flow chart for determining the standard air suction volume in the embodiment.

[0085] Specifically, the adsorption module has a preset suction volume Bc for the first working mode of the adsorption module in the initial working mode. If the control unit determines that the dust concentration in the environment does not meet the standard, the control unit adjusts the suction volume of the first working mode of the adsorption module according to the difference between the detected dust concentration and the dust concentration detection threshold. The adjusted suction volume is the regulated suction volume Bt.

[0086] Set Bt=Bc+(Dj-Dz)×E, where E is the adjustment parameter of the dust concentration difference on the suction volume of the adsorption module.

[0087] In this embodiment, E is set to 1.8 m. 6 / mg×min.

[0088] By testing the dust concentration in the environment after the adsorption unit has completed adsorption, the dust concentration in the environment can be obtained in real time. In the case of excessive concentration, the working mode of the adsorption module is adjusted according to the dust concentration, ensuring the control of the dust concentration in the mining environment and ensuring the effective adsorption of dust during the mining operation.

[0089] Specifically, the adsorption module is provided with a rated threshold value for suction volume. If the regulated suction volume is greater than the rated threshold value for suction volume, the control unit controls the adsorption module to operate at the rated threshold value for suction volume and controls the spray unit to start.

[0090] In this embodiment, the rated threshold of the air suction volume is 3.5m 3 / min;

[0091] In the case where the operation of a single adsorption module cannot meet the dust removal requirements, liquid is sprayed into the air through the spray unit to absorb the remaining dust in the environment and ensure that the dust concentration in the underground environment is within a reasonable range.

[0092] Specifically, the value of the standard air suction volume is related to the humidity and temperature of the underground environment. The value is inversely proportional to the humidity and directly proportional to the temperature.

[0093] The control unit is provided with a standard temperature value Wb and a standard humidity value Sb. The control unit obtains the actual temperature W and the actual humidity S of the mining environment and calculates the standard air intake volume:

[0094] If W≤Wb, and S≥Sb, then Bz=b;

[0095] If W>Wb, and S≥Sb, then Bz=b+(W-Wb)×z1;

[0096] If W≤Wb, and S<Sb, then Bz=b+(Sb-S)×z2;

[0097] If W>Wb, and S<Sb, then Bz=b+(W-Wb)×z1+(Sb-S)×z2;

[0098] Wherein, b is the basic value of standard air intake volume, z1 is the compensation value calculated by temperature difference for standard air intake volume, and z2 is the compensation value calculated by humidity difference for standard air intake volume. In this embodiment, b=1.4m 3 / min, z1=0.2m 3 / min×℃,z2=0.9.

[0099] Under the same environment, the higher the temperature or the lower the humidity, the greater the amount of dust during the mining process. Therefore, by detecting the temperature and humidity of the mining environment and adjusting the value of the standard air suction volume, it is ensured that the dust can be effectively adsorbed during the mining operation.

[0100] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
