Detailed Implementation
[0014] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an assembled steel structure fireproof coating spraying device.
[0015] like Figures 1-4 As shown, this utility model discloses a prefabricated steel structure fireproof coating spraying device, including a conveyor belt 1; a first motor 2 is installed on one side of the conveyor belt 1 to drive the transmission belt to work; spraying frames 3 are installed on both sides of the conveyor belt 1; mounting plates 4 are slidably installed on the spraying frames 3; a second motor 5 is installed at the bottom of the spraying frames 3; a belt 6 is installed on the shaft of the second motor 5 and connected to the mounting plate 4; the second motor 5 drives the mounting plate 4 to slide on the spraying frames 3 through the belt 6; a spray gun 7 is installed on the mounting plate 4 facing the conveyor belt 1; a paint tank 8 is installed on one side of the conveyor belt 1; a mixing tank 9 is installed inside the paint tank 8; a stirrer 10 is rotatably installed inside the mixing tank 9; a third motor 11 is installed on the top of the paint tank 8 to drive the stirrer 10 to rotate; a discharge pipe 12 is installed at the bottom of the mixing tank 9 and extends to the outside of the paint tank 8; a liquid pressure pump 13 is connected to the outside of the paint tank 8 via the discharge pipe 12; a conveying pipe 14 is connected to the spray gun 7 and communicates with the discharge pipe 12.
[0016] Combination Figures 1-4As shown, the steel structure to be sprayed is placed on the conveyor belt 1. The first motor 2 drives the conveyor belt 1 to transport the steel structure to the spraying frame 3. The second motor 5 drives the belt 6 to slide the mounting plate 4 on the spraying frame 3. By adjusting, the spray gun 7 is aligned with the position of the steel structure to be sprayed. The liquid pressure pump 13 is started to discharge the fireproof coating in the mixing tank 9 of the paint tank 8 through the discharge pipe 12, and then transport it to the spray gun 7 through the clinker pipe for spraying the fireproof coating on the steel structure. The construction efficiency is high, the spraying effect is uniform, and the finished product effect is good. At this time, the fireproof coating to be used is in the mixing tank 9 of the paint tank 8. The third motor 11 drives the agitator 10 to stir the fireproof coating in the mixing tank 9 to prevent the thick fireproof coating to be used from clumping and agglomerating. This prevents the fireproof coating from settling and agglomerating, helps to maintain the uniformity of the fireproof coating, and avoids the situation of clumping and clogging the conveying pipe 14 or the spray gun 7 during subsequent use. This makes the spraying effect of the fireproof coating on the steel structure uniform and smooth, and increases the efficiency of the spraying work.
[0017] A heating chamber 15 is provided between the paint tank 8 and the mixing tank 9; a heater 16 is provided in the paint tank 8 relative to the heating chamber 15; multiple heating rods 17 extend from the heater 16 into the heating chamber 15. Water is added into the heating chamber 15 between the paint tank 8 and the mixing tank 9, and then the heater 16 controls the heating rods 17 to heat the water in the heating chamber 15, thereby increasing the temperature of the fire-retardant paint in the mixing tank 9, increasing the fluidity of the fire-retardant paint, and further increasing the uniformity of the fire-retardant paint in conjunction with the stirring of the agitator 10, thus improving the finished product effect of the steel structure spraying.
[0018] A filter screen 18 is installed at the connection point between the mixing tank 9 and the discharge pipe 12; scrapers 19 are installed on both sides of the agitator 10 opposite to the filter screen 18. The filter screen 18 is used to filter out any sediment or agglomerates in the fireproof coating, preventing them from entering the conveying pipe 14 and the spray gun 7 and causing blockage. When the third motor 11 drives the agitator 10 to stir the fireproof coating, the scrapers 19 installed on the agitator 10 opposite to the filter screen 18 scrape down and crush the sediment or agglomerates filtered by the filter screen 18, and then stir the mixture evenly by the agitator 10.
