Flame spraying gun mainly used for laying water-proof coiled material

Abstract

A flame spray gun essentially for paving water-proof coils is provided, which relates to the spraying, baking and heating equipment for paving waterproof coils. The spray gun comprises a mixture air distribution valve 1, a mixed-air delivery pipe 6, a burning head 7, and a fixing support 10. The mixture air distribution valve comprises an inner pipe 11, an intermediate casing pipe 14 and an outer pipe 17. The burning head comprises a sandwich air disc for burning head 8 or a hollow air pipe for burning head 8', the air disc 8 or the air pipe 8' is provided with a plurality of flame nozzles 9. The invention connects a hose with LPG and compressed air, the dead weight is light, the invention is easy and flexible for handheld construction, the labor intensity is reduced; by using LPG as energy, especially compressed air for supporting combustion, the temperature is high, fire is strong, the surfaces of waterproof coils can melt rapidly, but the temperature rise in the inner layer is low, the structure and the waterproof property of the whole material are not damaged, the construction efficiency is high, the quality is good, and the construction cost is much lower than using a gasoline blowtorch.

Description

Technical field:

[0001] The invention relates to heating technology, mainly relates to spraying and baking heating equipment used for laying waterproof coiled material, specifically refers to a flame spray gun used for laying waterproof coiled material. Background technique:

[0002] At present, most of the roof waterproofing adopts the laying of new SBS waterproof membrane, which is made of modified asphalt as the base material and coated with a layer of aluminum reflective film or sand layer on the surface. The surface is sprayed and baked and melted and pasted on the surface of the building. The gasoline blowtorch is pressurized in the gasoline tank of the blowtorch with its own 11 air pump, so that the gasoline is atomized and sprayed out at high speed through the nozzle, and the temperature is very high. It can be used for spraying and heating in many ways, and it is also used for laying waterproof membrane Spray to heat. Gasoline blowtorches have two disadvantages fo...
