Problems solved by technology

[0006] On the basis of the design and application of the two-component nano-material spray gun, the present invention aims at the problem of the relationship between the mixing structure of the internal mixing chamber of the existing spray gun and the relationship between the material mixing flow rate, and the problem of insufficient injection volume of the nozzle when large-area spraying is carried out. The structure of the spraying device is further improved, and the purpose is to provide a two-component nano-material spraying device with simple structure, convenient assembly and disassembly, uniform mixing and rapid spraying

Embodiment 1

[0025] A two-component nano-material spraying device of the present invention can be produced by mechanical processing and manufacturing methods and plastic blow molding or injection molding processing and manufacturing methods. The device system is operated under pressure, and the production and installation of spray guns and parts are accurately matched. .

[0026] figure 1 Among them, the present invention makes two material storage tanks 3 of the same specification and size, and communicates with the material bin A and the material bin B in the spray gun 1 through two plastic feed pipes 2 respectively, forming a two-component nano-material spraying device.

[0027] Wherein, after the top of the tank in the storage tank 3 is fixedly connected with the tank guide pipe 7 and connected with the filling valve 6, the feed guide pipe 2 is connected; Material storage tank 3 is connected with back rope 4 on the back frame 5, and is used for conveniently implementing spraying pers...

Embodiment 2

[0036] According to the production method and usage method of Example 1, if the harmful gas is blocked in the coal mine tunnel, the material storage tank 3 should be filled or injected with MDI: 5-10kg, aerosol (chlorodifluoromethane): 0.5~1.0kg, pressure: 1.5~2.5MPa; another material storage tank 3 is poured into spraying combination polyether; 4~8kg, aerosol (chlorodifluoromethane): 2~3kg, pressure: 1.5~2.5 MPa seal, when spraying, open the filling valve 6, and then open the feed pipe control valve 50 of the gun body feed bin A and the feed pipe control valve 51 of the gun body feed bin B on the spray gun handle 14 and adjust the material ratio, and then adjust the switch The size of the handle control screw 46 controls the amount of spraying, and then the spray gun switch handle 47 is pressed to quickly block the tunnel. It can also be used for spraying on the top of buildings for leak prevention, thermal insulation, heat insulation, etc., and for the establishment and use ...

Embodiment 3

[0038] 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 3 should be charged or injected with 3~5Kg of polyurethane elastic prepolymer and trichloroethylene The solvent is 0.5-2.5MPa, and the other material storage tank 3 is filled or injected with 0.5-2Kg of diamine or glycol cross-linking agent, and the pressure is 1.5-2.5MPa. When spraying, open the filling valve 6, and then turn the spray gun handle 14 Open the feed pipe control valve 50 of the gun body feed bin A and the feed pipe control valve 51 of the gun body feed bin B to adjust the material ratio, then adjust the size of the switch handle control screw 46 to control the spraying amount, and then press the spray gun switch The handle 47 can quickly block the gap in the mine tunnel.

Abstract

The invention discloses a bi-component nanometer material spraying device, which comprises a spraying pistol and a material storage tank communicated by a feeding pipe, wherein a blending bunker of the spraying pistol is provided with a primary jet blending bunker, a secondary counter current blending bunker and a tertiary overflow blending bunker; a tip of the nozzle blending bunker is communicated with an elliptic nozzle and a round nozzle; a frame carrier is arranged between two material storage tanks and is connected with a rope; and a tank feeding pipe, a filter screen and a mixing blade are arranged in each material storage tank. The device sets the primary jet blending, secondary counter current blending and tertiary overflow blending in the spraying pistol according to the characteristics of the physical distribution principle so as to simplify the blending structure of the spraying pistol to the utmost extent, and has a simple structure, is convenient to assemble, disassemble or replace and clean, and makes materials evenly mixed. The spraying device is suitable for spraying application of various bi-component nanometer materials in various situations.

Description

technical field [0001] The invention relates to a two-component material spraying device composed of a spray gun, a material guide pipe and a material storage tank, in particular to a two-component nano-material spray gun composed of a spray gun nozzle, a material mixing chamber, a gun body and a handle. Background technique [0002] The "foam caulking agent spray gun" of CN2505181Y includes a gun shaft, a gun body and a handle. This structural feature is mainly suitable for narrow gap filling, and the spraying amount is insufficient for quickly closing holes or roadways, and there is no material distribution device. [0003] The "foam distribution gun" of USP4399.930, the patent structure device is composed of two raw material storage tanks connected with a spray gun through a feed pipe, and the structure of the spray gun is provided with a feed valve on the handle, and connected to the spray body through the nozzle. The feed inlet is provided with slots on both sides of th...
