[0023] A voltage regulator tube 21, a cooling tube 22, a housing 23, a first solenoid valve 31, a second solenoid valve 32, and a sandblasting valve port 33;

[0024] The third solenoid valve 211 . DETAILED DESCRIPTION

[0025] like Figures 1 to 3 As shown, the utility model proposes a mobile sandblasting machine, comprising:

[0026] A gas tank 1, wherein the gas tank 1 is pressurized by a screw air compressor 4, and the gas tank 1 is used to store the pressurized gas;

[0027] The airflow regulating device 2 is connected to the gas tank 1 and the sandblasting pot 3 respectively, cools the gas delivered from the gas tank 1, and discharges the gas into the sandblasting pot 3;

[0028] A sandblasting pot 3, which is filled with sand material, and the air delivered by the airflow regulating device 2 is used to pressurize the sandblasting pot 3;

[0029] The mobile sandblasting machine of the utility model is used to pressurize the gas tank 1 through the screw air compressor 4. Since the gas will cause a certain temperature rise after pressurization, when the high-pressure gas in the gas tank 1 is discharged, it will first pass through the airflow regulating device 2 to cool down, and the air pressure will be stabilized by the airflow regulating device 2. When the pressure tends to be stable and the temperature drops to a suitable range, the gas is transported toward the sandblasting pot 3, so that the gas pressurizes the sandblasting pot 3 and squeezes the sand stored in the sandblasting pot 3. Figure 1 As shown, the lower end of the sandblasting pot 3 is provided with a sandblasting valve port 33 for spraying sand. When the sandblasting pot 3 is pressurized, the sandblasting valve port 33 is opened to allow the sand to be sprayed out from the sandblasting valve port 33, or a nozzle or a connecting pipe can be connected to the sandblasting valve port 33 to spray the sand along the nozzle. It is necessary to explain that this article does not limit the nozzle or the connecting pipe connected to the sandblasting valve port 33. This article only regards the sandblasting pot 3 and the sandblasting valve port 33 as functional explanations and limitations. In actual use, they can be replaced as the use scenario changes without changing the structural principle, and the above explanation is also applicable to each structure in the utility model.

[0030] Furthermore, a first solenoid valve 31 is connected to the side of the sandblasting pot 3, and the first solenoid valve 31 is connected to the airflow regulating device 2 through an adjusting component to control whether the gas in the airflow regulating device 2 is delivered to the sandblasting pot 3 through the adjusting component.

[0031] Furthermore, the airflow regulating device 2 includes a voltage regulator tube 21, a cooling tube 22, and a shell 23. The two ends of the cooling tube 22 are respectively connected to the gas tank 1 and the voltage regulator tube 21, and the voltage regulator tube 21 is connected to the first solenoid valve 31 through the regulating component. The pressurized gas in the gas tank 1 flows into the sandblasting pot 3 along the cooling tube 22, the voltage regulator tube 21, the regulating component and the first solenoid valve 31 in turn, and a third solenoid valve 211 is also installed at the lower end of the voltage regulator tube 21. The third solenoid valve 211 is used to control the discharge of liquid in the voltage regulator tube 21. Since the gas will squeeze the water molecules in the gas during the pressurization process, and when the gas with a slightly higher temperature after pressurization is quickly cooled, the condensation of water molecules will be accelerated. Therefore, the water molecules will condense into water droplets in the voltage regulator tube 21, and the third solenoid valve 211 is to discharge the water droplets, and the cooling tube 22 and the shell 23 are filled with coolant or water to improve the cooling efficiency through coolant or water.

[0032] In the prior art, sandblasting machines generally face problems such as unstable pressurization effect, shortened equipment life and increased safety hazards due to the lack of a cooling system. The airflow regulating device 2 in the utility model is designed to address these problems. It cools down the high-temperature gas through the cooling pipe 22, solving the problem that excessive temperature may affect the sandblasting effect and equipment life; at the same time, the voltage regulator 21 stabilizes the gas pressure to ensure the uniformity and consistency of the sandblasting effect. In addition, the airflow regulating device 2 also regularly discharges water droplets in the voltage regulator 21 through the third solenoid valve 211 to prevent moisture from affecting the sandblasting effect or equipment operation. It can be said that the design of the airflow regulating device 2 effectively solves the problems existing in the background technology and improves the overall performance and use effect of the mobile sandblasting machine.

[0033] A preferred technical solution, the cooling tube 22 is in a spiral structure, and the cooling tube 22 is connected to the upper end side of the voltage-stabilizing tube 21. The spiral design allows the cooling tube 22 to have a longer path at the same length, thereby increasing the contact area between the gas and the inner wall of the cooling tube. This design is conducive to faster transfer of heat to a cooling medium such as air or water, thereby improving heat dissipation efficiency. When the gas flows in the spiral tube, it will be guided by the tube wall for many times to form a spiral flow path. This flow mode is conducive to enhancing convection inside the gas, making the heat more evenly distributed and promoting the transfer of heat to the tube wall. In addition, compared with a straight tube, the design of the spiral tube has a gentler bending part, which reduces sudden turns and vortex generation during the gas flow process, thereby reducing pressure loss. This means that under the same pressure, the spiral tube can transport more gas and improve the overall efficiency of the system;

[0034] After the screw air compressor 4 pressurizes the gas tank 1, the high-temperature and high-pressure gas enters the spiral cooling tube 22. Since the cooling tube 22 has a large heat dissipation area and enhanced convection effect, the gas quickly transfers heat to the tube wall during the flow and dissipates heat through a cooling medium such as air or water. The cooled gas enters the voltage-stabilizing tube 21, where the pressure is stabilized and the temperature further drops to a suitable range. Since the design of the spiral tube reduces pressure loss, the voltage-stabilizing tube 21 can maintain a high gas pressure to ensure that the sandblasting pot 3 obtains sufficient pressurization effect. Finally, the cooled and pressure-stabilized gas enters the sandblasting pot 3 through the regulating component and the first solenoid valve 31, pressurizes the sand in the pot and sprays it out. Since the gas temperature is effectively controlled throughout the process, the sandblasting effect is more uniform and stable, and the equipment life is also extended.

[0035] Furthermore, the regulating component includes a three-way pipe 5, and the airflow regulating device 2 is connected to the first solenoid valve 31 and the sandblasting valve port 33 through the three-way pipe 5, and the gas flowing out through the voltage regulator tube 21 flows to the first solenoid valve 31 and the sandblasting valve port 33 respectively through the three-way pipe 5, and by controlling the opening and closing of the first solenoid valve 31, it is determined whether the gas flowing out of the voltage regulator tube 21 pressurizes the sandblasting pot 3; the side of the sandblasting pot 3 is also connected to a second solenoid valve 32 for discharging the gas in the sandblasting pot 3, and the three-way pipe 5 controls whether it is connected to the sandblasting valve port 33 through a pneumatic ball valve 6, and the voltage regulator tube 21 is connected to the pneumatic ball valve 6 and the first solenoid valve 31 respectively through the three-way pipe 5. A radiator 7 is also provided on the side of the airflow regulating device 2, and the radiator 7 is arranged close to the side of the airflow regulating device 2, and when the radiator 7 is working, the airflow is blown toward the airflow regulating device 2;

[0036] The first solenoid valve 31 is located on the connection path between the three-way pipe 5 and the sandblasting pot 3. Its main function is to control whether the gas flowing out of the voltage regulator tube 21 enters the sandblasting pot 3 for pressurization. By opening and closing the first solenoid valve 31, the user can accurately control the gas pressure in the sandblasting pot 3, thereby achieving a more precise sandblasting operation. When sandblasting is not required, closing the first solenoid valve 31 can prevent the gas from entering the sandblasting pot 3, thereby reducing unnecessary energy consumption. By controlling the inflow of gas, the pressure in the sandblasting pot 3 can be prevented from being too high, thereby protecting the equipment from damage and extending the service life;

[0037] The second solenoid valve 32 is located on the side of the sandblasting pot 3 and is used to discharge the gas in the pot. After the sandblasting operation is completed, the second solenoid valve 32 can be opened to quickly empty the gas in the sandblasting pot 3 to prepare for the next operation. There is no need to wait for the gas to be naturally emptied. The second solenoid valve 32 can quickly complete the gas discharge, thereby improving the overall operation efficiency;

[0038] The third solenoid valve 211 is installed at the lower end of the voltage regulator tube 21, and is used to control the discharge of liquid in the voltage regulator tube, mainly to discharge water droplets condensed during the gas cooling process. Regularly opening the third solenoid valve 211 can discharge water droplets in the voltage regulator tube 21 to prevent moisture from damaging the equipment and keep the equipment dry. The timely discharge of water droplets helps to maintain the performance of the voltage regulator tube 21 and the entire airflow regulating device 2, ensuring the stable operation of the equipment. By eliminating potential moisture problems, the third solenoid valve 211 helps to reduce corrosion and wear of the equipment, thereby extending its service life.
