DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0029] Example 1:

[0030] like Figure 1-7 As shown, the mining belt intelligent spray dust removal device provided by the utility model includes: a control end 1, multiple detection mechanisms 2 and multiple dust removal mechanisms 3; the detection mechanisms 2 and the dust removal mechanisms 3 are arranged one-to-one next to the belt conveyor, and at least one group of detection mechanisms 2 and dust removal mechanisms 3 are arranged at the head of the belt conveyor, the control end 1 is arranged at the head of the belt conveyor, and the detection mechanism 2 is arranged behind the dust removal mechanism 3, that is, when the belt conveyor is running, it first passes through the dust removal mechanism 3 and then passes through the corresponding detection mechanism 2; the detection mechanism 2 includes a dust concentration detection component and a wind pressure detection component, which are respectively used to detect the dust concentration above the belt conveyor and the wind pressure on the windward side; the dust removal mechanism 3 includes a door frame 4 erected above the belt conveyor, a water spray pipe 5 is installed on the door frame 4, and a plurality of nozzles 6 are installed downward on the water spray pipe 5, a hydrogel storage tank 7 is provided on one side of the door frame 4, and a hydrogel storage tank 7 is installed on the hydrogel storage tank 7 It is equipped with a pressure pump 8, one end of the water spray pipe 5 is closed, and the other end is connected to a mixing tank 9 through a pipeline. Two branch pipes 10 are installed at one end of the mixing tank 9, one branch pipe 10 is connected to the pressure pump 8, and the other branch pipe 10 is connected to the high-pressure water source (the high-pressure water pipe under the well). A flow meter 11 and an electric control valve 12 are installed on the branch pipe 10. The pressure pump 8, the flow meter 11 and the electric control valve 12 are connected to the control end 1. When in use, the hydrogel in the hydrogel storage tank 7 is drawn into the branch pipe 10 by the pressure pump 8, and the high-pressure water 10 enters another branch pipe 10. The water and hydrogel enter the mixing tank 9 and mix, and then enter the water spray pipe 5 through the pipeline, and then are sprayed out through the nozzle 6 to form a fine water mist of hydrogel, which adsorbs and reduces dust in the air. Because the hydrogel has greater viscosity, the fine water mist of hydrogel is more likely to stick to the dust, and the dust reduction efficiency is higher and the speed is faster. At the same time, the detection mechanism 2 detects the dust concentration and wind pressure in the air and transmits the data to the control terminal 1. The control terminal 1 automatically executes according to the preset program. When the dust concentration is higher than the maximum preset value, the control terminal 1 automatically controls the pressure pump 8 to start and the electric control valve 12 to open, so that the water and hydrogel can mix and reduce dust. When the dust concentration is lower than the minimum preset value, the control terminal 1 automatically controls the pressure pump 8 to stop and the electric control valve 12 to close, and the dust removal ends. During the spray dust reduction process, the control terminal 1 can control the opening and closing degree of the electric control valve 12 according to the flow rate changes of the flow meter 11, thereby adjusting the use ratio of the hydrogel and, correspondingly, the water use ratio. If the opening and closing degree of the electric control valve 12 is increased or decreased at the same time, the spray speed of the nozzle 6 is increased or decreased, thereby speeding up or slowing down the dust removal speed.

[0031] By setting up the control terminal 1, the detection mechanism 2 and the dust removal mechanism 3, dust removal operations can be automatically performed according to the changes in the dust concentration in the air near the belt conveyor. A mixture of water and hydrogel is used as the dust removal medium, which has a stronger ability to wrap and adsorb dust, improves the dust removal efficiency, and saves water to a certain extent.

[0032] Example 2:

[0033] like Figure 4 As shown, the mixing tank 9 includes a shell 13, with connecting pipes at both ends of the shell 13 and one end connected to the branch pipe 10. A plurality of filter screens 14 are installed in the shell 13. After water and hydrogel enter the shell 13, they pass through multiple layers of filter screens 14 in succession. The hydrogel 14 is gradually dispersed by the filter screens 14, so that the water and hydrogel are evenly mixed. In addition, the filter screens 14 can filter out debris in the water to prevent the debris from clogging the nozzle 6.

[0034] By providing a mixing tank 9 including a housing 13 and a plurality of filter screens 14 , the hydrogel and water can be mixed conveniently and impurities in the water can be filtered.

[0035] Example 3:

[0036] like Figure 2 As shown, a buffer tank 15 is installed on one side of the gantry 4, one end of the buffer tank 15 is connected to the mixing tank 9, and the other end is connected to the water spray pipe 5 through a high-pressure resistant rubber tube. The buffer tank 15 buffers the mixture of water and hydrogel entering the water spray pipe 5, which can make the water pressure more stable and less volatile, and thus the fine water mist of hydrogel sprayed from the nozzle 6 is more stable and will not change drastically.

[0037] By installing a buffer tank 15 between the water spray pipe 5 and the mixing tank 9, the water pressure can be stabilized, the fluctuation can be reduced, and the sprayed hydrogel mist can be made more stable.

[0038] Example 4:

[0039] like Figure 2 and Figure 5-7 As shown, an adjustment plate 16 is fixedly installed on the water spray pipe 5, and a plurality of slots 18 are provided on the adjustment plate 16. A limiting hole 22 is provided on the door frame 4, and a pin rod 20 is inserted into the limiting hole 22. The pin rod 20 passes through one of the slots 20, thereby fixing the angle of the adjustment plate 16, that is, the angle of the water spray pipe 5 is fixed, and the direction angle of the nozzle 6 is fixed. If it is necessary to adjust the spray angle of the nozzle 6, pull out the pin rod 20, rotate the adjustment plate 16, and rotate the water spray pipe 5 along its axial direction by a certain angle, thereby changing the direction of the nozzle 6 and adjusting the spray angle. Then, insert the pin rod into the limiting hole and the corresponding slot 18.

[0040] By providing the adjustment plate 16 , the slot 18 , the limiting hole 22 and the pin 20 , the angle of the nozzle 6 can be manually adjusted.

[0041] Example 5:

[0042] like Figure 2 and Figure 6As shown, a connecting piece 17 is provided on the water spray pipe 5, and the connecting piece 17 includes a mounting ring 19 that is sleeved on the water spray pipe 5. The mounting ring 19 is connected to the pin rod 20, and a handle 21 is installed on one side of the mounting ring 19. When in use, the pin rod 20 is movably connected to the water spray pipe 5 through the connecting piece 17, so that it is not easy to be lost, and the handle 21 is used to facilitate the movement of the pin rod 20.

[0043] By providing the connecting piece 17, the pin rod 20 can be hung on the water pipe 5 after being pulled out, which makes it less likely to be lost and more convenient to find.

[0044] Example 6:

[0045] like Figure 7 As shown, a T-shaped support seat 23 is installed at the bottom end of the gantry 4, and more than one fixing hole is opened on the support seat 23. A two-way threaded rod 24 is installed between the support seat 23 and the gantry 4, and the two ends of the two-way threaded rod 24 are respectively threadedly connected to the gantry 4 and the support seat 23. When in use, the support seat 23 is fixed in the tunnel by a ground anchor or a steel chisel, and the two-way threaded rod 24 is rotated to make the support seat 23 close to or away from the bottom of the gantry 4, and then the level of the gantry 4 is adjusted so that it is horizontally erected above the belt conveyor (including the head). Compared with the method of connecting the gantry 4 to the belt conveyor frame, the vibration of the belt conveyor is large when it is running, and the bracket is connected to the frame, which makes the gantry 4 vibrate greatly. However, when it is fixed on the ground, the vibration is much reduced.

[0046] By providing the support base 23 and the bidirectional threaded rod 24 , the gantry 4 can be conveniently fixed on the tunnel floor and its level can be adjusted.

[0047] Working principle: When in use, the hydrogel in the hydrogel storage tank 7 is pumped into the branch pipe 10 by the pressure pump 8. The high-pressure water 10 enters another branch pipe 10. The water and hydrogel enter the mixing tank 9 to mix. Then, they enter the water spray pipe 5 through the pipeline and are sprayed out through the nozzle 6 to form a fine water mist of hydrogel, which absorbs and reduces dust in the air. Since the hydrogel has a stronger viscosity, the fine water mist of hydrogel is more likely to stick to the dust, and the dust reduction efficiency is higher and faster. At the same time, the detection mechanism 2 detects the dust concentration in the air and transmits the data to the control terminal 1. The control terminal 1 automatically executes according to the preset program. When the dust concentration is higher than the maximum preset value, the control terminal 1 automatically controls the pressure pump 8 to start and the electric control valve 12 to open, so that the water and hydrogel can mix and reduce dust. When the dust concentration is lower than the minimum preset value, the control terminal 1 automatically controls the pressure pump 8 to stop and the electric control valve 12 to close, and the dust removal ends.
