Embodiment 1

[0068] like figure 1 , figure 2 , image 3 and Figure 4 As shown, a foam aerosol injector used for dust-proof application of foam in drilling on the surface of a building is composed of an aerosol can 1 and a hand-held valve-type accelerator, wherein the aerosol can 1 is a metal integral can, The inner wall of the tank needs to be coated with anti-corrosion plastic grease. The valve 2 of the aerosol can is installed on the top of the aerosol can 1, either a male valve or a female valve. This embodiment only takes the male valve as an example. -3 and sealing ring 2-4. The valve body 2-2 is located in the aerosol can 1, the upper end of the valve body 2-2 is fixedly connected to the top of the aerosol can 1, and the lower end of the valve stem 2-1 extends into the bottom of the valve body 2-2 from top to bottom. The inner cavity is supported by the spring 2-3, and the upper end of the valve stem 2-1 protrudes from the top surface of the aerosol can 1. An inner cavity 2-1...

Embodiment 2

[0074] like Figure 5 , Image 6 , Figure 7 and combine image 3 , Figure 4 As shown, a foam aerosol dispenser used for dust-proof application of foam in drilling on the surface of a building consists of an aerosol can 1, a booster, a flexible conduit 6, a nozzle 8 and an extension pipe 9 and other components. Wherein the structure and assembly relationship of the aerosol can 1 and the aerosol can valve 2 are the same as those of the product embodiment 1; the drilling tool 15 is an electric hammer, and the structure is the prior art, and will not be repeated here. The accelerator is composed of a casing 4-1, a rubber ring 4-2, a trigger 4-3 and a push rod 4-4. The lower part of the rubber ring 4-2 is set on the upper end of the casing 4-1, and is firmly connected with the upper end of the casing 4-1. The upper part of the rubber ring 4-2 is an elastic expansion port 4-2a, and the elastic expansion port 4-2a is sleeved on the lower end of the front handle 15a of the drillin...

Embodiment 3

[0079] like Figure 8 and combine image 3 , Figure 4 As shown, a foam aerosol injector used for dust-proof application of foam in the surface drilling of a building is composed of an aerosol can 1, a promoter, a conduit 12 and a spray head 8, wherein the structure and assembly of the aerosol can 1 The relationship is the same as that of product embodiment 1, and will not be repeated here. The accelerator also adopts the existing structure, including the trigger 5 and the cap 11, and the cap 11 is forcibly buckled and pressed on the body of the aerosol can 1 and the crimping seal of the top cover by interference fit. The trigger 5 is connected to the cap 11 through a rotatable hinge point, and a discharge channel is arranged at the rear end of the trigger 5, the inlet of the discharge channel communicates with the inner chamber 2-1a of the valve stem 2-1, and the outlet of the discharge channel communicates with the inner cavity 2-1a of the valve stem 2-1. One end of the c...

Abstract

The invention discloses dustproof application of foam in drill hole on the surface of building. The application comprises the following steps: after the drill hole position is selected, foam is sprayed to the drill hole position to form foam pipe so as to bury work head of drilling toll; then the drilling tool is started to rotate the work head to drill hole, and the generated mud, sand and dust are absorbed by the foam pile; and finally the foam pile containing the mud, sand and dust at the periphery of the hole opening is cleaned up. The invention also discloses a sprayer which comprises an aerosol pot and a promoter, wherein the valve of the aerosol pot can be opened under the function of the promoter, so the object in the aerosol pot can be sprayed out through a nozzle to form the foam. The invention effectively solves the problems that the mud and sand splash and the dust flies in the split construction of building which pollute the environment and adjacent facilities and harm health of operator, and develops the use field of foam aerosol.

Description

technical field [0001] The invention relates to a dust-proof method of foam drilling in the surface of a building and a foam aerosol injector used therein, which is mainly used to prevent the environment from being polluted by flying silt and dust when tools are used to partially break open the building. and adjacent facilities to protect the health of workers. Background technique [0002] At present, when drilling holes on the walls, floors, and ceilings of masonry concrete buildings, drilling tools such as electric hammers are generally used to directly carry out such drilling. It causes mud and sand to splash and dust to fly, which not only pollutes the environment and adjacent facilities, but also endangers the health of operators; at the same time, mud, sand and dust are scattered everywhere, making it extremely inconvenient to clean up. In order to solve the problem of dust prevention when drilling holes on the surface of masonry concrete buildings, the general metho...
