Description

Technical Field

[0001] This utility model relates to the technical field of underground coal mine spraying equipment, specifically a lightweight, fully pneumatic thin-spray device for dual-liquid applications. Background Technology

[0002] Coal mines are generally characterized by abundant water, damp roadways, and exposed surrounding rock and coal face, which easily lead to weathering, breakage, and leakage of harmful gases. The supporting metal components, such as steel beams, steel anchors, metal trays, and metal protective nets, are susceptible to severe corrosion due to the humid environment, which in turn significantly affects the stability of the roadway support. Therefore, shotcrete and thin-layer spraying of new materials are often used to seal and solve the problems of weathering of the surrounding rock and corrosion of metal components, anchors, and metal nets.

[0003] The equipment currently used for spraying thin-film coating materials in underground coal mines has several problems. For example, the equipment is large and heavy, making it difficult to move, and requiring enhanced safety measures. Furthermore, electric spraying equipment involves many components and has high safety requirements, such as the necessity of explosion-proof electrical switches and the laying of mining cables, resulting in low construction efficiency for new thin-film coating materials in underground coal mines. Conventional two-component spraying methods use combinations of dual-diaphragm pumps and dual-plunger pumps, complicating the construction process. The pumps also generate significant noise, are difficult to clean and maintain, and adjusting the two-component ratio is inconvenient, especially during emergencies or rapid spraying and sealing for damage repair, leading to low efficiency. Based on this, a lightweight, fully pneumatic thin-spray device for dual-liquid applications is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight, fully pneumatic thin-spray device for dual-liquid applications, in order to solve many problems and shortcomings of existing thin-spray material spraying equipment in coal mines, such as inconvenience in movement, complex accessories, and low construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A lightweight, fully pneumatic, thin-spray device for dual-liquid applications includes a material-containing main tank.

A sealing gasket 9 is installed between the upper sealing fastening plate 18 and the main tank 3. A large pressure-sealing cover plate 17 and a small pressure-sealing cover plate 14 are respectively installed on both sides of the main tank 3. The lightweight, flexible casters 4 can flexibly turn, meeting the need for easy and flexible turning at multiple angles. The fixed-direction support casters 6 mainly serve a supporting function, and their movement is restricted while providing guidance.

[0023] In one embodiment, such as Figure 3 As shown, the main material container 3 has a partitioned cavity, dividing the cylinder into two chambers. Each chamber can store the thin-sprayed two-component material separately, ensuring the independence and stability of each component material before mixing.

[0024] In one embodiment, such as Figure 1As shown, a movable handrail 1 is provided at the upper end of the material feeding main barrel 3. The movable handrail 1 is fixed by the handrail support plate 2 on the side wall of the material feeding main barrel 3. The movable handrail 1 is a round tube that can be easily held by hand and can conveniently push the spraying device at various angles.

[0025] In one embodiment, such as Figure 1 As shown, the bottom of the material feeding tank 3 is provided with a first discharge port 5, and the bottom of the material feeding tank 3 is provided with a second discharge port 7 on one side of the first discharge port 5. The interfaces of the first discharge port 5 and the second discharge port 7 are connected by a switch control, which can be used for the respective output of the two-component materials, and the ratio of the two-component materials can be adjusted.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, a large pressure sealing cover plate 17 and a small pressure sealing cover plate 14 are respectively provided on both sides of the upper sealing fastening plate 18. The large pressure sealing cover plate 17 and the small pressure sealing cover plate 14 are located above the two cavities inside the material storage body barrel 3. The large pressure sealing cover plate 17 and the small pressure sealing cover plate 14 are used for sealing and pouring in the two-component liquid material, respectively.

[0027] In one embodiment, such as Figure 1 and Figure 2 As shown, a first fixing ring 10 is provided on the upper sealing fastening plate 18 on one side of the large pressure sealing cover plate 17, and a second fixing ring 12 is provided on the upper sealing fastening plate 18 on one side of the small pressure sealing cover plate 14. The first fixing ring 10 and the second fixing ring 12 are rectangular structures, which facilitates limiting and fixing.

[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, a large clamping wrench 16 is provided between the first fixing rings 10 above the large clamping sealing cover plate 17, and a small clamping wrench 13 is provided between the second fixing rings 12 on the small clamping sealing cover plate 14. Both the large clamping sealing cover plate 17 and the small clamping sealing cover plate 14 are tightened and sealed by clamping bolts 15 on the large clamping wrench 16 and the small clamping wrench 13 to ensure a firm seal.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, a pressure gauge regulating valve group 11 is provided on one side of the upper closed fastening plate 18, and a safety valve 19 and a pressure relief valve 20 are provided on the side of the upper closed fastening plate 18 away from the pressure gauge regulating valve group 11. The pressure of the introduced compressed air can be reduced by adjusting the regulating valve of the pressure gauge regulating valve group 11, and the pressure relief valve 20 can release the compressed air.

[0030] Working principle: In use, loosen the clamping bolt 15. When the first fixing ring 10 and the large clamping wrench 16 can be easily disassembled, remove the large clamping wrench 16 and the large clamping sealing cover 17. Then, pour the two-component liquid into one side of the material-containing main tank 3 through the orifice. Stop adding material when it reaches a certain height near the top. Then, reverse the operation to tighten the large clamping sealing cover 17, the large clamping wrench 16, and the clamping bolt 15 to ensure a firm seal. Then, follow the same steps to tighten the clamping bolt 15. When the second fixing ring 12 and the small clamping wrench 13 can be easily disassembled, remove the small clamping wrench 13 and the small clamping sealing cover 14. Then, pour the two-component liquid into the other side of the material-containing main tank 3 through the orifice. Stop adding material when it reaches a similar height. Then, reverse the operation again to ensure a firm seal. The two components inside the material-containing main tank 3... The bottoms of each compartment are completely separated and not interconnected. The mixing ratio of the two-component liquid can be accurately matched according to the volume and the opening of the control valve. The pressure of the introduced compressed air can be reduced by adjusting the pressure regulating valve of the pressure gauge regulating valve group 11. The compressed air, in the closed space, acts through the pressure tank to transport the two-component liquid in the material storage tank 3 through the first discharge port 5, the second discharge port 7, the control valve, and the connecting hose at the bottom of each compartment to the front spray gun and the spraying work area. During the spraying process, the moving handle 1 can be flexibly operated to move the thin spraying device, such as placing the device to the side to make room for other equipment, vehicles, etc. At the same time, the device can also be placed close to the spraying work area to ensure the quality of the sprayed material. After a single feeding and spraying is completed, the pressure relief valve 20 is opened to release the compressed air, and then the next feeding cycle can be started according to the above steps.
