Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a building construction spraying device. Background Technology

[0002] Building construction is a systematic project that transforms architectural designs from blueprints into reality. It encompasses multiple stages. The initial phase involves site leveling and foundation construction to lay a solid foundation for the entire building, including piling for large structures to ensure stability. During the main construction phase, various trades work closely together: steelworkers tie reinforcing bars, carpenters erect formwork, and concrete workers pour concrete, building the framework layer by layer. The processes related to spraying equipment are also crucial. Before construction, the spraying area must be precisely planned and the paint selected. During construction, the spraying equipment ensures precise material supply and even spraying. After construction, rigorous inspection is conducted to guarantee the aesthetic appeal and durability of the walls. Furthermore, it involves plumbing and electrical installations, interior and exterior finishing, and other aspects; only through coordinated work at each stage can a qualified building be created.

[0003] Current spraying equipment suffers from several shortcomings. First, most lack a dedicated purification system for harmful components in paint, allowing harmful air generated during spraying to be directly emitted, posing a threat to human health. Second, even when similar purification structures exist, filters and activated carbon plates are often complex to install and difficult to disassemble, leading to frequent clogging and malfunctions after prolonged use. This inconvenience for staff replacement significantly reduces purification efficiency, making it impossible to consistently and effectively guarantee air quality.

[0004] In response to this technical problem, this application proposes a building construction spraying device. Utility Model Content

(Refer to...) Figure 3 , Figure 5 and Figure 7 An intake fan 23 is fixedly connected inside the intake pipe 7. The intake fan 23 and intake pipe 7 draw air mixed with harmful components from the paint into the air collection box 8. A first filter 16 is connected to the left end of the intake pipe 7 to filter out particulate matter in the air. A centrifugal fan 11 is installed at the rear of the air collection box 8 to expel the air entering the air collection box 8. A second filter 20, a HEPA filter, is connected to the rear of the air collection box 8 to further filter smaller particles in the air, improving the filtration effect of the air collection box 8. The second filter 20 is fixed by a limiting component. An activated carbon plate 19 for purifying the gas is inserted into the rear of the air collection box 8. A box cover 9 is inserted into the top of the air collection box 8. (Refer to...) Figure 2 A stirring rod 14 is rotatably connected inside the bucket lid 12, and a stirring blade 15 is fixedly connected to the outer wall of the stirring rod 14. A motor 10 is installed on the top side of the bucket lid 12, and the drive end of the motor 10 is fixedly connected to the top of the stirring rod 14. The motor 10 drives the stirring rod 14 to rotate, which in turn drives the stirring blade 15 to rotate, thereby stirring the paint to prevent coagulation and affecting the conveying. A plate 17 is fixedly connected to the outer wall of the first filter screen 16. (Refer to...) Figure 4 A groove is provided at the left end of the intake pipe 7, and an insert plate 17 is inserted into the groove. A baffle 18 is slidably connected inside the groove, and the bottom side of the baffle 18 is inserted into the bottom side of the groove. By inserting the insert plate 17 into the groove and inserting the bottom side of the baffle 18 into the groove, the first filter screen 16 is fixed to the intake pipe 7. (Refer to...) Figure 5 and Figure 6 The air collection box 8 has two slide rails 21 fixedly connected to the rear side inside. The second filter screen 20 is slidably connected between the two slide rails 21. The rear end of the top slide rail 21 is inserted with a pin 22. The second filter screen 20 is fixed between the two slide rails 21 by sliding the second filter screen 20 between the two slide rails 21 and inserting the pin 22 into the top slide rail 21.

[0029] Reference Figure 1 and Figure 8 A paint pump 3 is installed on the bottom side of the barrel 2. A hose 4 is fixedly connected to the output end of the paint pump 3. A spray gun 5 is fixedly connected to the end of the hose 4. Paint is transported from the barrel 2 to the spray gun 5 through the paint pump 3 and the hose 4, and then sprayed out through the spray gun 5. A push rod 13 is fixedly connected to the top side of the bottom plate 1. A round tube for replenishing paint is fixedly connected to the top side of the barrel lid 12. A flared mouth 6 for expanding the air intake range is fixedly connected to the left end of the air inlet pipe 7. A sealing ring 24 for improving the sealing between the air collection box 8 and the box lid 9 is fixedly connected to the bottom side of the box lid 9.

[0030] Working principle: First, the device is pushed to the area where spraying is required via push rod 13. Then, motor 10 is started to drive stirring rod 14 to rotate, which in turn drives stirring blade 15 to rotate and stir the paint to prevent coagulation and affect delivery. Then, paint pump 3, air intake fan 23 and centrifugal fan 11 are started simultaneously. Paint is transported from tank 2 to spray gun 5 through paint pump 3 and hose 4. Then, the paint is sprayed out through spray gun 5. During spraying, air intake fan 23 will blow out air mixed with harmful components in the paint. Air is drawn into the air collection box 8 through the air intake pipe 7. Before the air enters the air intake pipe 7, the first filter screen 16 filters out particulate matter in the air. When the air enters the air collection box 8 from the air intake pipe 7, the activated carbon plate 19 adsorbs harmful components in the air. Then, the centrifugal fan 11 draws the filtered air out of the air collection box 8 and discharges it to the outside. When the air enters the centrifugal fan 11 from the air collection box 8, it passes through the second filter screen 20 to further filter smaller particles in the air, thereby improving the filtration effect of the air collection box 8.
