When the liquid level sensor sensitively captures that the water level in the box body 101 is lower than a preset lower limit value and cannot guarantee water supply to the water storage box 6, an electric signal is immediately sent to the control module, the control module rapidly analyzes the signal by means of an intelligent algorithm, accurately instructs the intelligent flow valve 104 to increase the opening degree, accelerates the water inflow by adjusting the position of the valve core of the electric regulating valve, and vice versa. When the water level reaches the upper limit value, the control module drives the intelligent flow valve 104 to reduce the opening degree and finely controls the water inflow.

[0025] Further, the inner wall of the bottom of the box 101 is provided with a guide slope 106 on both sides, and a sewage outlet 107 is arranged on the inner wall of the bottom between the two guide slopes 106. The sewage outlet 107 is rotatably connected with a sealing cover plate 108 on one side edge, and the sealing cover plate 108 is connected with the box 101 through a locking mechanism.

[0026] The inner wall of the bottom of the box 101 is designed as a guide slope 106 on both sides, and the slope gradient is set to be between 10°-30°, so that the settled dirt can quickly and naturally converge to the sewage outlet 107 under the action of gravity.

[0032] The air inlet pipe of the fan 2 is connected with the two dust collectors 4 through the three-way pipe 3. The three-way pipe 3 is made of hard pipe material to ensure the stability of the two dust collectors 4 during work. The dust collector 4 is made of light high-strength plastic or thin steel plate stamping and is shaped like a horn. The opening area is optimized to increase the dust absorption range. The dust collector 4 is symmetrically distributed on both sides of the box body 101 and the opening is directed to the high dust source area such as the ore loading and unloading point and the crushing processing area. The dust is efficiently sucked by the strong suction of the fan.

[0033] Further, the filter screen 401 is integrally arranged at one side of each dust collector 4.

[0034] The filter screen 401 closely inlaid at the opening of the dust collector 4 is made of stainless steel wire and the mesh number is scientifically selected according to the fan power and dust characteristics.

[0035] Please refer to Figure 4 The water storage box 6 is in a semicircular structure and a plurality of atomizing nozzles 7 are evenly distributed on the curved outer wall of the water storage box 6 in a semicircular shape.

[0036] The semicircular water storage box 6 is customized according to the arc of the front side of the box body 101 and is integrally formed of anti-corrosion aluminum alloy material. The semicircular and evenly distributed atomizing nozzles 7 are selected according to the spray coverage requirement and the number is between 10 and 20. The spray particle size is between 10 and 100 microns. The water pumped by the water pump 5 is evenly distributed to each atomizing nozzle 7 after being delivered to the water storage box 6 through the high-pressure resistant hose. The spray angle can be adjusted through the self-adjusting structure of the nozzle. Thus, the spray coverage is maximized. The unique shape of the semicircular water storage box 6 and the semicircular distribution of the atomizing nozzles 7 make the water mist evenly distributed in the area where dust reduction is needed, improve the dust reduction effect of the spray and enhance the local air quality control capability of the mine construction site.

[0037] Further, one end of the L-shaped rotating pipe 601 is rotatably connected to the bottom surface of the water storage box 6 and communicates with the inside of the water storage box 6. The other end of the L-shaped rotating pipe 601 also communicates with the atomizing nozzle 7. A driven gear 602 is fixedly sleeved on one end of the L-shaped rotating pipe 601 and is engaged with a driving gear 603 on one side. The driving gear 603 is fixedly sleeved on one end of the output shaft of an adjusting motor 604. The adjusting motor 604 is fixedly installed on the bottom surface of the water storage box 6. A wind direction sensor is arranged on the outer wall of one side of the water storage box 6 and is electrically connected with a control module.

[0038] The wind direction sensor selects a high-precision ultrasonic wind direction sensor, is installed at the top of the water storage box 6 in an open and unobstructed position, monitors the wind direction in real time, and transmits the wind direction information to the control module in the form of an electric signal several times per second. The control module has a wind direction judgment algorithm. Once a wind direction change signal is received, the adjusting motor 604 is immediately driven. The adjusting motor 604 selects a small and precise servo motor, drives the driving gear 603 fixed on one end of the output shaft of the adjusting motor 604 to rotate accurately, the driving gear 603 is in engagement with the driven gear 602, and then the driven gear 602 drives the L-shaped rotating pipe 601 to rotate stably, so that the direction of the atomizing nozzle 7 at one end of the L-shaped rotating pipe 601 is adjusted, so that the atomizing nozzle 7 at one end of the L-shaped rotating pipe 601 sprays dust in the dust flow direction according to the wind direction.

[0039] Working principle: first, connect the water inlet pipe 103 to the water supply pipeline to supply water to the box 101, and the water level is at least higher than the water pumping end height of the water pump 5. The fan 2 sucks dust-containing air through the two sides of the dust collecting cover 4 connected by the three-way pipe 3, and the dust collecting cover 4 faces the dust source. The dust-containing air passes through the filter plate 102 into the sewage cavity, and the purified air enters the clean water cavity through the filter plate, and is discharged through the exhaust pipe 105. At the same time, the water pump 5 pumps water from the clean water cavity to the semicircular water storage box 6, and the several atomizing nozzles 7 equally distributed on the semicircular water storage box 6 can form a fan-shaped spraying area in front of the box to reduce dust. In operation, the intelligent flow valve 104 cooperates with the liquid level sensor to control the water inflow according to the water level, ensuring stable water supply. The wind direction sensor on the surface of the water storage box 6 monitors the wind direction, drives the adjusting motor 604 to rotate, and drives the nozzle to turn to face the wind, thereby improving the dust reduction effect and protecting air quality.

[0040] It should be noted that the specific type and size of the intelligent flow valve 104, the fan 2, the water pump 5, the adjusting motor 604, the control module, the liquid level sensor and the wind direction sensor need to be determined according to the actual size of the device. The specific selection calculation method uses the existing technology in the art, so it will not be described in detail.
