Asphalt spraying device for waterproof roll

Abstract

The invention discloses an asphalt spraying device for a waterproof roll. The asphalt spraying device comprises a sliding rod, wherein a first atomization shell is arranged at the left end of the sliding rod; a second atomization shell is arranged at the right end of the sliding rod; a first feed pipe is arranged at the bottom of the first atomization shell; a second feed pipe is arranged at the bottom of the second atomization shell; spray pipes are in threaded connection with the front face of the first atomization shell and the front face of the second atomization shell correspondingly; spray heads are arranged at the ends, away from the sliding rod, of the spray pipes; air is sprayed out in advance, and dust on the surface of the waterproof roll can be removed; when an L-shaped plate continues to slide rightwards, a pipette is exposed at the moment, and negative pressure is generated around the pipette due to the air compression effect, so that liquid in a storage box is sucked out, and the atomization function is achieved; and similarly, when a grip is loosened and the pipette is firstly closed by the L-shaped plate, an air compression pipe continuously exhausts air, residualmixed liquid in the spray pipes is sprayed out, and the spray heads are prevented 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
