Description

Technical Field

[0001] The utility model relates to the field of gas cooling devices, in particular to an airflow regulating device for a sandblasting machine. Background Art

[0002] In the field of high-pressure gas technology, high-pressure gas cylinders, as key equipment for storing and transporting high-pressure gas, are widely used in many fields such as industry, scientific research, and medical treatment. However, existing high-pressure gas cylinders often lack effective gas cooling devices during design and use. This problem has caused a series of technical difficulties and safety hazards in practical applications. When the high-pressure gas cylinder is used in a sandblasting machine, the gas in the high-pressure gas cylinder will be compressed. Due to the intensified collision between gas molecules during the compression process, a large amount of heat will be generated, causing the gas temperature to rise sharply, especially under continuous working or high-pressure working conditions. The increase in gas temperature is particularly significant. In view of the above problems, it is particularly important to equip the high-pressure gas tank of the sandblasting machine with an effective gas cooling device. Utility Model Content

[0003] The utility model provides an airflow regulating device for a sandblasting machine, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] An air flow regulating device for a sandblasting machine comprises a pressure stabilizing tank, a cooling pipe and an electromagnetic valve. The cooling pipe is connected to the side of the pressure stabilizing tank.

The cross section of the flow channel is arranged in a bow-shaped structure. The air outlet pipe is connected to the surface of the outermost component monomer.

[0020] like Figures 1 to 3As shown, the utility model proposes an air flow regulating device for a sandblasting machine, an air flow regulating device for a sandblasting machine, 1. comprising a pressure stabilizing tank 1, a cooling pipe 2, and a solenoid valve 3, the cooling pipe 2 is connected to the side of the pressure stabilizing tank 1, high-pressure gas flows into the pressure stabilizing tank 1 along the cooling pipe 2, and is transported outward through the air outlet pipe 4 connected to the side of the pressure stabilizing tank 1, the pressure stabilizing tank 1 is composed of internal and external nested component monomers, and there is a flow channel for air flow between all component monomers, the cross section of the flow channel is arranged in a bow-shaped structure, the air outlet pipe 4 is connected to the surface of the outermost component monomer, and the two ends of the flow channel are respectively connected to the cooling pipe 2 and the air outlet pipe 4. Based on the above content, the working principle of the utility model can be summarized as follows:

[0021] High-pressure gas introduction: High-pressure gas is first introduced through cooling pipe 2. The function of cooling pipe 2 is to initially reduce the temperature of the gas and reduce the water vapor content in the gas to avoid problems caused by condensation of water vapor in the subsequent cooling process;

[0022] Cooling and pressure stabilization in the pressure stabilizing tank: After the high-pressure gas enters the pressure stabilizing tank 1, it flows and cools through a specially designed flow channel in the pressure stabilizing tank. The pressure stabilizing tank 1 is composed of internal and external nested component monomers. The flow channel cross-section formed between these monomers is a bow-shaped structure. This design helps to enhance the turbulent effect of the gas and improve the heat exchange efficiency. At the same time, the pressure stabilizing tank ensures the stability of the output gas by controlling the gas flow and pressure;

[0023] Heat exchange and cooling: When the gas flows in the flow channel inside the surge tank, it exchanges heat with the wall of the surge tank to further reduce the gas temperature. The bow-shaped design of the flow channel not only increases the path length of the gas flow, but also promotes the contact area between the gas and the wall, thereby improving the cooling efficiency;

[0024] Gas output: The gas after being fully cooled and pressure-stabilized is transported outward through the gas outlet pipe 4 connected to the side of the pressure-stabilizing tank for subsequent use.

[0025] The bow-shaped flow channel design allows the gas to constantly change direction during the flow process, enhancing the turbulence effect. Turbulence can promote heat exchange between the gas and the wall and improve cooling efficiency. The bow-shaped flow channel significantly extends the gas flow path compared to the straight flow channel. The gas flows in a longer path, which means there is more time for heat exchange with the wall, thereby further reducing the gas temperature. The complex design of the flow channel increases the contact area between the gas and the wall. A larger contact area means that more heat can be transferred from the gas to the wall, and then dissipated into the surrounding environment, improving the cooling effect.

[0026] Furthermore, the inner and outer nested component monomers are respectively a top cover 11, a second sleeve 13, and an outer tube body 14. The first sleeve 12 is installed at the lower end of the top cover 11. The second sleeve 13 is sleeved outside the first sleeve 12 and fixed to the surface of the top cover 11. The outer tube body 14 is sleeved outside the second sleeve 13. The top cover 11 and the first sleeve 12 are provided with a connected channel 1, and the second sleeve 13 is provided with a channel 2. The outer tube body 14 is provided with a channel 3. Channels 1, 2, and 3 are connected, and channels 1, 2, and 3 constitute the flow channel. Moreover, channels 2 and 3 are U-shaped structures, and a first air outlet 131 is provided on the upper side of the second sleeve 13. Channels 2 and 3 are connected, and channel 3 is connected to the air outlet pipe 4 connected to the upper part of the outer tube body 14, and as shown Figure 3 The first air outlet holes 131 are evenly distributed on the upper outer side of the second sleeve 13 , so as to form a smooth air flow through the evenly arranged first air outlet holes 131 and ensure the stability of the gas in the structure.

[0027] The high-pressure gas is first introduced through the cooling pipe, and after preliminary cooling, it enters the pressure-stabilizing tank. In the pressure-stabilizing tank, the gas flows through channel one between the top cover 11 and the first sleeve 12, and U-shaped channel two in the second sleeve 13, and enters the also U-shaped channel three through the first air outlet 131 on the upper part of the second sleeve 13. In channel three, the gas further exchanges heat with the wall of the component to achieve cooling. Finally, the cooled gas is discharged to the outside through the air outlet pipe 4 connected to the upper part of the outer tube body 14 for subsequent use. During the whole process, the gas flows through the extended path and is fully cooled in the pressure-stabilizing tank, which effectively reduces the temperature and stabilizes the pressure.

[0028] Furthermore, the inner lower end of the outer tube body 14 is a curved surface that gradually deepens from the edge to the middle, and a second air outlet hole 141 is provided in the middle of the lower end of the outer tube body 14, the solenoid valve 3 is inserted into the second air outlet hole 141, and is three-phase connected with the channel, and the cooling tube 2 is a spiral structure, and the two ports of the cooling tube 2 are respectively an air inlet end and an air outlet end, the air inlet end is bent toward one end of the air outlet pipe 4, and the air outlet end is arranged away from the air inlet end;

[0029] Furthermore, in order to further improve the cooling efficiency, the gas cooling device of the present invention can be placed in a coolant or water to form a liquid cooling effect.

[0030] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
