Description

Technical Field

[0001] The utility model relates to the field of Venturi guns, in particular to a secondary oxygen supply device of a Venturi gun. Background Art

[0002] The Venturi gun is a highly efficient combustion device. When the fuel fluid passes through a narrow pipe, its speed increases and its pressure decreases. By adjusting the ratio of gas and air, it achieves full mixing and efficient combustion, thereby improving combustion efficiency and flame stability. During the oxidation reaction between gas and air, insufficient oxygen may be introduced, resulting in insufficient oxidation reaction, which in turn causes incomplete combustion of the fuel and produces carbon monoxide. There are safety hazards during use, and the Venturi gun needs to be oxygenated secondary. Adequate oxygen intake can ensure sufficient combustion of the fuel. The existing secondary oxygen supply device for the Venturi gun is cumbersome to operate, which will prolong the time and intensity of oxygen supply, and is limited in use.

[0003] In view of the above problems, a secondary oxygen supply device for a Venturi gun is now developed. Utility Model Content

[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0019] A secondary oxygen supply device for a venturi gun, such as Figures 1-4 As shown, it includes a gun barrel 1, which is an integrated cast structure with stronger structure. The right part of the gun barrel 1 is threadedly connected to a connector 2, which is a detachable connection structure. A through hole 3 is provided on the connector 2. The front and rear sides of the middle part of the connector 2 are connected to guide blocks 4, which are arc-shaped mechanisms that fit the inner wall of the connector 2. An adjusting member 5 is threadedly connected to the connector 2, and the adjusting member 5 is provided with anti-slip grooves 6. The anti-slip grooves 6 protrude from the surface of the adjusting member 5. The front side of the connector 2 is connected to an oxygen inlet pipe 7, which is located on the right side of the guide block 4. The right part of the connector 2 is connected to a guide member 8, which is a C-shaped structure. A gas pipe 9 is connected to the guide member 8, and the left part of the gas pipe 9 is threadedly connected to the right part of the connector 2.

[0020] It should be noted that the Venturi gun is a highly efficient combustion device. When the fuel fluid passes through a narrow pipe, its velocity increases and its pressure decreases. By adjusting the ratio of gas and air, it can achieve full mixing and efficient combustion, thereby improving combustion efficiency and flame stability. In the process of oxidation reaction between gas and air, insufficient oxygen may be introduced, which will lead to incomplete oxidation reaction and incomplete combustion of fuel to produce carbon monoxide. There are safety hazards in the use process. The Venturi gun needs to be oxygenated twice. Adequate oxygen intake can ensure full combustion of the fuel. Connect the oxygen inlet pipe 7 to the oxygen device and connect the gas to the gas pipe 9. The gun rod 1 is an integrated The casting characteristic structure is stronger, wear-resistant and not easy to damage. The anti-slip groove 6 will be used to rotate the adjusting part 5, and the adjusting part 5 will move to the left. According to the actual combustion situation of the fuel, the adjusting part 5 will be adjusted to a suitable position, thereby driving the oxygen inlet pipe 7, the guide part 8 and the gas pipe 9 to move to the left, which will discharge the air inside the adjusting part 5 and the connecting part 2, so that the pressure inside the adjusting part 5 and the connecting part 2 is lower than the external pressure. Under the guiding action of the guide block 4, the oxygen in the oxygen inlet pipe 7 will be quickly transported to the adjusting part 5, thereby quickly completing the secondary oxygen supply of the Venturi gun. This method is simple to operate, shortens the original secondary oxygen supply time of the Venturi gun, and is more convenient to use.
