[0001] The invention relates to a hydraulic sandblasting cutting device, in particular to a hydraulic sandblasting cutting device used in uranium mining and a use method thereof, which is applied in the field of hydraulic sandblasting cutting devices. Background Art

[0002] As an emerging technology, hydraulic sandblasting cutting process combines high-pressure water flow with sandblasting. It can not only accurately clean the deposits and corrosion on the surface of the equipment, but also effectively perform the cutting operation, avoiding the risks and defects that may be caused by traditional methods.

[0003] The existing hydraulic sandblasting slitting device is a technology that uses a mixture of high-pressure water flow and sand particles for cutting. It is mainly used for slitting operations of hard materials such as rocks and concrete. This technology combines the advantages of water jet cutting and sandblasting technology. After the water and sand particles are mixed by a high-pressure pump, they are sprayed at high speed to the surface of the material to be cut through a nozzle. The grinding effect of the sand particles and the impact force of the water are used to achieve material cutting. Compared with traditional mechanical cutting methods, the hydraulic sandblasting slitting device has the advantages of fast cutting speed, high cutting accuracy, less damage to materials, and no pollution to the environment.

[0053] Second implementation method: Figure 6-Figure 7 As shown, it also includes an auxiliary control system, which includes a control module, a data processing module, a monitoring module, and a data storage module.

[0054] The control module is used to receive operating instructions and control the working state of the entire uranium mining hydraulic sandblasting cutting device, including starting, stopping and adjusting the working parameters of each component.

[0055] The data processing module is used to process and analyze the data transmitted by the monitoring module, and calculate various parameters of the device during operation according to the preset algorithm. The parameters include: hydraulic pressure, water flow, abrasive flow and high-pressure pipeline 1 rotation speed. The processing results are fed back to the control module. The control module determines whether the active nozzle 22 is blocked according to the analysis results of the monitoring data.

The data processing module processes and analyzes the monitoring data, calculates various parameters of the device when it is working, and feeds back the processing results to the control module so as to adjust the working parameters in time and optimize the cutting effect.

[0060] After completing the cutting task, the control module receives a stop command, turns off the motor and electromagnetic opening and closing valve, and stops the supply of high-pressure water flow, abrasive and gas.

[0061] The data storage module stores the historical data of this operation, including operation instructions, working status, monitoring data, etc., for subsequent analysis and troubleshooting.

[0062] This solution achieves rapid maintenance through pneumatic cleaning and switching of spare nozzles. When the movable nozzle 22 is blocked, it automatically switches to the fixed nozzle 24. Combined with the pneumatic cleaning function, equipment damage caused by blockage is avoided.

[0063] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
