[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figures 1 to 4 As shown, this embodiment provides a mobile carbon dioxide blasting dust suppression device for open-pit mines, including: a dust suppression medium storage tank, a dust suppression spray gun, a connecting device, a remote control device, a traction device, a motion mechanism and a dust detection device. Among them, the dust suppression medium storage tank is fixedly arranged on the motion structure, the dust suppression spray gun and the remote control device are fixedly installed on the top of the dust suppression medium storage tank, the traction device is connected to the motion mechanism, and the traction device is used to connect with the auxiliary mechanical equipment so as to use the auxiliary mechanical equipment to pull the device, and the remote control device controls the opening and closing of the dust suppression spray gun.

[0033] Specifically, in this embodiment, the dust suppression medium storage tank is divided into two sealed cavities, namely a first cavity and a second cavity. Liquid carbon dioxide is stored in the first cavity, and dust suppression water solvent is stored in the second cavity. The dust suppression spray gun is located above the second cavity, and the dust suppression spray gun is connected to the second cavity. A first solenoid valve is provided on the dust suppression spray gun, and the first solenoid valve is used to control the opening and closing of the dust suppression spray gun. At the same time, the first solenoid valve is electrically connected to the remote control device, and the operator can control the opening and closing of the first solenoid valve through remote control.

[0034] In addition, an air inlet, a pressure reducing valve pressure gauge and a safety valve are respectively provided on the top of the outer side wall of the first cavity. The operator injects high-pressure liquid carbon dioxide into the first cavity through the air inlet. The pressure reducing valve pressure gauge is used to display and adjust the pressure value of the high-pressure liquid carbon dioxide in the first cavity. The safety valve is to prevent the high-pressure liquid carbon dioxide from exceeding the maximum limit of the internal pressure of the first cavity.

[0035] A water inlet, an exhaust port and a pressure gauge are respectively provided on the outer side wall of the second cavity. The external aqueous solution is injected into the second cavity through the water inlet. The exhaust port is used to discharge the carbon dioxide entering the second cavity. The pressure gauge is used to detect the pressure in the second cavity in real time to prevent the pressure in the second cavity from being too high. When the pressure gauge detects that the pressure in the second cavity is too high, the gas can be exhausted through the exhaust port.

[0036] In addition, capacity monitoring devices are provided at the front end of the outer wall of the first cavity and the rear end of the outer wall of the second cavity, respectively. The capacity monitoring devices are used to observe the capacity of liquid carbon dioxide in the first cavity and the change of water level in the second cavity, respectively, so as to facilitate the operator to grasp the remaining materials in the first cavity and the second cavity in real time, and at the same time help the operator to make a blasting water plan in advance, effectively reducing the water cost.

[0037] In this embodiment, the connecting device includes a connecting pipe and a second solenoid valve, the second solenoid valve is used to control the opening and closing of the connecting pipe, one end of the connecting pipe is connected to the first cavity, the other end of the connecting pipe is connected to the second cavity, and the remote control device is electrically connected to the second solenoid valve. When the operator needs to remotely control, the operator first opens the second solenoid valve to allow the carbon dioxide in the first cavity to enter the second cavity, and then opens the first solenoid valve again, so that the carbon dioxide entering the second cavity compresses the dust suppression aqueous solution in the second cavity to be discharged through the dust suppression spray gun, thereby completing the spraying operation. In addition, a positioning module can also be added to the remote control device to provide the equipment GPS location information, so that the operator can grasp the location information of the mobile carbon dioxide blasting dust suppression device in the open-pit mine in real time. The remote control module in this embodiment can use a simple remote control module, or a single-chip microcomputer can be used to complete this function.

[0038] The moving mechanism is connected to the traction device, and the dust suppression medium storage tank is fixedly arranged on the moving structure. Specifically, in this embodiment, the moving mechanism includes a supporting chassis, a hydraulic support and a moving wheel. The front end of the supporting chassis is fixedly connected to the hydraulic support. The hydraulic support is used to lift the front end of the supporting chassis. The front and rear ends of the supporting chassis are respectively provided with moving wheels. The traction device and the supporting chassis are connected by a shock absorbing spring, and the shock absorbing spring can ensure the stability of the equipment during movement. The hydraulic support needs to be propped up in the dust removal state to prevent the blasting dust suppression device from deviating from the established working position during operation.

[0039] In addition, a moving wheel is provided on both sides of the front end of the supporting chassis, and two moving wheels are provided on both sides of the rear end of the supporting chassis. This is because the dust suppression medium storage tank has the same volume in the sub-compartments but different storage medium densities. In order to increase the stability of the equipment, a double moving wheel structure is adopted on the rear side.

[0040] The dust detection device is used to detect the dust generated during the blasting process. The dust device can control the opening and closing of the first solenoid valve and the second solenoid valve. Specifically, the dust detection device can detect the dust generated during the blasting process using optical principles, and instantly open the first solenoid valve and the second solenoid valve to perform dust suppression. When the dust concentration drops below the set threshold, the dust detection device will send a signal to close the first solenoid valve and the second solenoid valve to stop the dust suppression work, which greatly saves the water consumption of the dust suppression work during the blasting process and reduces the blasting cost.

[0041] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
