A bitumen spraying device for waterproof coiled material

Abstract

The invention discloses an asphalt spraying device for waterproof coiled material, which comprises a sliding bar, the left end of the sliding bar is provided with a first atomizing shell, and the right end of the sliding bar is provided with a second atomizing shell, the The bottom of the first atomization housing is provided with a first feed pipe, the bottom of the second atomization housing is provided with a second feed pipe, the first atomization housing and the second atomization housing The nozzles are threadedly connected to the front, and the nozzle is installed at the end of the nozzle away from the slide bar. At this time, the air is sprayed out in advance, which can remove the dust on the surface of the waterproof membrane. When the "L" shaped plate continues to slide to the right, At this time, the suction pipe leaks out. At this time, due to the negative pressure generated around the suction pipe due to the air compression, the liquid in the storage box is sucked out to realize the atomization function. Similarly, when the handle is released, when the "L" shape The plate is the first to close the suction pipe, and the air compression pipe continues to discharge air at this time, spraying out the residual mixed liquid in the nozzle to prevent the nozzle from being blocked.

Description

technical field [0001] The invention relates to the technical field of asphalt spraying, in particular to an asphalt spraying device for waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, in order to ensure waterproof To improve the waterproof performance of the coil, it is necessary to spray waterproof coating again on the surface of the coil made of impregnated petroleum asphalt and the rolled material. [0003] Waterproof coatings can be prepared from a variety of raw materials. Common waterproof coatings are made of emulsified asphalt and rubber latex mixed with a coagulant to form a rubber asphalt coating film, which is sprayed on the surface of the waterproof coil by air pressure. This waterproof coating has high tensile strength. It has the charac...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of asphalt-asphalt spraying device for waterproof coiled material, to solve the function of automatically adjusting the air pressure of the existing asphalt spraying device proposed in the above-mentioned background technology, it is impossible to adjust the output ratio of the mixture synchronously, before spraying The dust on the surface of the waterproof membrane cannot be removed in advance, and the residual mixture cannot be cleaned after spraying, which may easily cause nozzle blockage
