Fuel gas mixer and burner

Abstract

The invention provides a fuel gas mixer. The fuel gas mixer comprises a shell, a fuel gas inlet pipe, an oxidant gas inlet pipe, adjusting valves, a fuel gas mixing pipe and an oxidant gas mixing pipe, and the fuel gas inlet pipe and the oxidant gas inlet pipe are communicated to the two sides of the shell; the adjusting valves are arranged on the fuel gas inlet pipe and the oxidant gas inlet pipe; and the fuel gas mixing pipe and the oxidant gas mixing pipe are arranged in the shell, the fuel gas mixing pipe is communicated to the fuel gas inlet pipe, the oxidant gas mixing pipe is communicated to the oxidant gas inlet pipe, and through holes are formed in the fuel gas mixing pipe and the oxidant gas mixing pipe in the axial direction. By means of the fuel gas mixer, fuel gas and oxidant gas can be sufficiently mixed, burning of follow-up burnt fuel gas is sufficient, and burning flames are more even.

Description

technical field [0001] The invention belongs to the field of waterproof construction engineering equipment, and more specifically relates to a gas mixer and a burner. Background technique [0002] With the continuous development and progress of my country's economy, there are many major infrastructure projects in the country every year, involving roads, bridges, tunnels, etc., coupled with the rapid growth of real estate construction, all of which involve waterproofing construction. [0003] Existing construction of laying waterproof coiled material generally all is to lay on the position that needs waterproofing after fully heating waterproof coiled material, then compacts by roller. In the common manual heating operation, the worker holds a blowtorch and heats the coil for a certain period of time before laying. Due to the large surface width of the coil, it is necessary to reciprocate the heating with a hand-held blowtorch in a horizontal direction, and the heating effec...

AI Technical Summary

Problems solved by technology

Due to the large surface width of the coil, it needs to be reciprocated horizontally with a hand-held blowtorch, and the heating effect is uneven and takes a long time.

If multiple torches are used to heat at the same time, at least two workers are required to be responsible for heating at the same time, which increases man-hours and costs

[0004] In addition, some existing hot-melt paving and waterproofing membrane vehicles fix multiple spray guns on the shelf and heat the membrane after being ignited. Although labor costs are saved, the problem of uneven heating still exists, and fuel consumption large, wasteful
