Embodiment 1

[0023] The present invention can be made by mechanical manufacturing method and plastic blow molding or injection molding method, but the whole device system should be made according to the pressurized system, and the making and installation of the spray gun and parts should be accurately matched.

[0024] figure 1 Among them, the device of the present invention includes two metal material storage tanks (1), and a material guide valve (4) is connected by bolts on the storage tank top cover of the material storage tank (1). The material guide valve (4) is recommended to use "Ningbo The needle valve of model YSF-1” produced by Wan’an Valve Factory is threadedly connected with the feed pipe (5) in the tank at one end of the feed valve (4), and the other end is provided with a soft seal with a nut seal interface. The feed pipe (3) is connected and connected to the spray gun (2).

[0025] The main structure in the whole device is: in the material storage tank (1) is provided with th...

Embodiment 2

[0032] According to the preparation method and the use method of embodiment 1, if gaps such as coal mine roadways and mining areas are filled and plugged, the material storage tank (1) should be charged or injected with 3~5Kg of polyurethane elastic prepolymer and three Vinyl chloride solvent 0.5~2.5MP a , the other material storage tank (1) is filled or injected with 0.5-2Kg of diamine or glycol cross-linking agent, and the pressure is 1.5-2.5MP a , when spraying, open the material guide valve (4), and then open the first feed bin inlet pipe control valve (15) and the second feed bin inlet pipe control valve (16) on the handle of the spray gun to adjust the material ratio, and then Regulate the size of the spraying amount, then press the spray gun switch handle (41), and the gap in the mine can be filled and plugged.

Embodiment 3

[0034] According to the production method and usage method of Example 1, if a temporary thermal insulation tent is set up in the rescue and disaster relief process, it can be charged or injected into the material storage tank (1) with MDI: 5-10kg, aerosol (monochlorodifluoro Methane): 0.5~1.0kg, pressure: 1.5~2.5MP a ; In the other material storage tank (1), rush into the spraying combination polyether; 4~8kg, aerosol (chlorodifluoromethane): 2~3kg, pressure: 1.5~2.5MP a , Spraying on straw mats, woven tapes, canvas, etc. as the base material frame can quickly establish a temporary tent for cold insulation.

Abstract

The double-component self spraying apparatus includes material storing tank and spray gun connected via material pipe, and features the material guide pipe with stirring filter inside the material storing tank, the spray gun with connected spray head, gun body and handle, two material mixing bins with mixing balls inside the spray head, and the material flow controller set inside the handle. The present invention has once stirring of the materials and twice double component mixing so that the materials are resistance mixed fully. The present invention has the features of simple structure, easy assembling, disassembling, replacing and cleaning and no need of power and driving apparatus, and is suitable for spraying double component material in different fields, especially in mine.

Description

technical field [0001] The invention relates to a device for automatically spraying materials, in particular to a two-component material self-spraying device comprising a material storage tank, a material guide pipe and a spray gun. Background technique [0002] Various gas and liquid spraying devices have different shapes and sizes, different functions, and different applicable occasions. In the prior art, there is no ideal application spraying material and a spraying device with a wide range of spraying objects, especially a spraying device for rapid sealing and permanent plugging of coal mine underground roadways, and there is no ideal spraying device that can be used in coal mines. It is a material self-spraying spray gun with a wide range of application for uniform mixing of two-component materials in the spray gun. CN2505181Y "foam sealant spray gun" utility model patent, including gun shaft, gun body and handle, its main structural feature is that the part of the han...
