[0025]

[0026] Where: a is the required mixing ratio (mass ratio) of dust suppressant and water;

[0027] d is the spacing between each vertical row of holes on the belt;

[0028] ρ2 is the density of water;

[0029] Q1 is the water inlet flow rate;

[0030] n is the number of small holes in each vertical row on the belt;

[0031] ρ1 is the density of dust suppressant;

[0032] V1 is the volume of the small hole on the belt.

[0033] Compared with the prior art, the present invention has at least the following advantages:

[0034] (1) The present invention aims to solve the problem that the traditional dust suppression device is difficult to accurately control the amount of water and the dosage of dust suppression. By installing a liquid level meter inside the water tank, a liquid level monitor is used to monitor the liquid level in real time, and a signal is transmitted to the control system to accurately control the amount of water in the water tank. A belt with holes is used to transport the dust suppressant, and the amount of dust suppression in the water tank is accurately controlled. At the same time, the dust suppressant and water can be fully added to the water tank at the same time according to the required amount, which greatly improves the accuracy of production, avoids material waste, and is more economical and environmentally friendly. For the problem that different types of dust suppressants require different amounts, the belt speed can also be adjusted to ensure that the dust suppressant and water are still fully added to the water tank at the same time according to the required amount, which has a wider applicability.

[0035] (2) The present invention uses an intelligent control system, which is easy to operate and has clear control logic. The system can automatically stop or start according to the changes in the liquid level, saving energy and increasing the service life of the equipment. The intelligent control system of the present invention greatly reduces operating errors and improves the safety of the system.

[0036] (3) The different stirring directions of the stirring blades in the left water tank and the right water tank of the present invention improve the stability of the system, reduce the risk of violent fluctuations in the device, and reduce safety hazards; at the same time, the streamlined structure and small hole structure of the blades improve the solution mixing efficiency, reduce flow resistance, reduce the burden on the stirring motor, and save energy.

[0037] (4) The present invention is also equipped with a dust concentration monitoring device to monitor the dust concentration at the location of the device in real time and dynamically adjust the water pump pressure within a set threshold range to adjust the spraying rate of the fog cannon, save water resources, and improve dust removal efficiency.

When a certain dust concentration threshold is reached, the dust concentration monitor 15 transmits the real-time dust signal to the controller 16, and then the controller 16 adjusts the pumping pressure of the water pump 30, and further adjusts the spraying rate of the fog cannon 5;

[0063] S4: After the water pump 30 is started, the intelligent dust suppressant adding and spraying device enters the automatic control state. If the operation of the device is stopped, disconnect the water inlet pipe 14, and then press the control system switch button 162, the water pump switch button 161, and the stirring motor switch button 163 in sequence to cut off the power to the liquid level monitor 17, the controller 16, and the dust concentration monitor 15 (after the right water tank 3 reaches the liquid level threshold, perform the same operation as above).

[0064] The amount of dust suppressant added to the dust suppressant storage box 9 in step S1 of the present invention satisfies the amount of dust suppressant required by a water tank for multiple times; preferably, by using the belt speed regulator 162 to adjust the speed of the belt 81, when the dust suppressant solution in the water tank reaches the liquid level threshold, the required water and dust suppressant in the water tank are just added, and the further setting of the speed of the belt 81 can be calculated according to the following formula:

[0065]

[0066] Where: a is the required mixing ratio (mass ratio) of dust suppressant and water;

[0067] d is the spacing between each vertical row of holes on the belt;

[0068] ρ2 is the density of water;

[0069] Q1 is the water inlet flow rate;

[0070] n is the number of holes in each vertical row on the belt;

[0071] ρ1 is the density of dust suppressant;

[0072] V1 is the volume of the small hole on the belt.

[0073] The intelligent dust suppressant adding and spraying device of the present invention may encounter the following special situations when in use:

[0074] (1) Stop using the water tank after all the dust suppressant solution in the tank has been sprayed.

[0075] Assume that when the dust suppressant solution is ready to stop, the left water tank 2 is filled with dust suppressant solution, and the dust suppressant solution in the right water tank 3 is being transported to the fog cannon 5 through the soft water pipe 31 by the water pump 30 for spraying. The worker manually disconnects the water inlet pipe 14, and then presses the control system switch button 162 to turn off the control system, and the belt and all stepper motors return to the default state. Due to the principle of communicating vessels, the left water tank 2 and the right water tank 3 will maintain the same liquid level, and the water pump 30 is still not turned off, and continues to transport the solution until the spraying of the two water tanks is completed.

[0076] (2) Prepare the location of the mobile device

[0077] The device is a vehicle-mounted device, so the location of the device can be changed by simply moving the vehicle. Assume that the left water tank 2 is filled with dust suppressant solution before moving, and the dust suppressant solution in the right water tank 3 is being transported to the fog cannon 5 by the water pump 30 through the soft water pipe 31 for spraying. After the worker completes step S4, it can be moved. After moving to the designated position, the worker executes steps S1, S2, and S3, but due to the principle of communicating vessels, the signal transmitted by the liquid level is (0~1, 0~1), and the control system has no control response under this signal. Therefore, to restart the automatic control system, the staff only needs to turn the control system switch button 162, and any rotation direction left or right is acceptable, and then the automatic control system can be started again.

[0078] In summary, the present invention is easy to operate and has clear control logic. The automatic operation of the device can be achieved through a few simple steps. At the same time, the automated control can achieve precise dosage and avoid material waste, which greatly improves the accuracy of production and has significant environmental and economic benefits.
