Description

Technical Field

[0001] The utility model relates to the technical field of slag micropowder, and more specifically to a water spraying device for slag micropowder. Background Art

[0002] The main purpose of slag powder is to mix it in cement and add it to commercial concrete. Its utilization methods are different. In summary, it can be mainly manifested in three forms: admixture form, admixture form, and main admixture form. Its main function is to increase the early strength of cement and concrete and improve certain properties of concrete (such as workability, early strength improvement, and reduction of hydration heat, etc.).

[0003] Slag powder can replace the cement in various concrete and cement products in equal amounts, which can significantly improve the comprehensive performance of concrete and cement products. As a new admixture for high-performance concrete, slag powder has the advantage of improving various properties of concrete.

[0004] Slag powder is in small particles after grinding and generates dust when moving. Long-term inhalation will affect human health. Existing devices spray water to reduce dust on slag powder. If water is sprayed just after filling, it will offset the falling slag powder and cause the slag powder to float. In addition, only the surface of the slag powder can be sprayed with water locally, and the spraying is insufficient. Utility Model Content

[0030] The device or equipment models involved in this article are as follows:

[0031] Motor model: YBS-160;

[0032] The model of booster pump 230 is: G260WB.

[0033] Working principle: When the device needs to be used, the booster pump 210 is used to drive the water in the water tank 240 to circulate. The water passes through the water pipe 250, the base 270, the water injection tank 220 in sequence, and finally sprays out from the water spray port 260. The slag powder is poured into the device through the injection port 110 and falls into the working bin 120. The motor 310 drives the screw rod 340 to rotate, and the slag powder entering the working bin 120 is transported and turned. When the baffle 280 is pulled open, the front part of the baffle 280 is pulled out of the baffle slot. 230 slides upward and engages with the bolt at the rear part of the baffle 280. The water fills the water injection tank 220 and is sprayed out from all the water spray ports 260 to spray the slag powder in the working bin 120 throughout the entire process. The height of the filter screen 281 is adjusted by adjusting the knob on the top of the water injection tank 220 and the raising and lowering of the threaded column 282 to prevent larger slag from entering the water injection tank 220 and causing pollution. The slag is transported in the working bin 120 to the discharge port 130 and falls out of the device to complete the water spraying.

[0034] It is worth noting that in order to enable the device to spray water continuously, a hole is left on the top of the water tank 240 through integral molding, and the hole can be connected to an external water pipe so that the water in the water tank 240 can be constantly replenished. Specifically, a hole is provided on the top of the water tank 240, and the hole can be connected to an external water pipe to continuously supply water to the water tank 240.

[0035] Furthermore, in order to prevent slag particles in the working bin 120 from entering the water injection tank 220 during rotation and causing pollution, a filter screen 281 is placed in the water injection tank 220. In order to control the lifting and lowering of the filter screen 281 inside the water injection tank 220, a threaded column 282 is connected to the top of the filter screen 281 by welding, and a circular hole is left at the top of the water injection tank 220 through one-piece molding. The threaded column 282 passes through the circular hole and is connected to the knob 283. The inner wall of the knob 283 has a thread that cooperates with the threaded column 282. The threaded column 282 is raised and lowered by rotating the knob 283, thereby driving the filter screen 281 to rise and fall. Specifically, a threaded column 282 is provided on the top of the filter screen 281, and a knob 283 is provided on the top of the threaded column 282. The top of the water injection tank 220 is provided with a circular hole. The threaded column 282 passes through the circular hole and is connected to the knob 283. The knob 283 is rotated to adjust the lifting and lowering of the filter screen 281 inside the water injection tank 220.

[0036] Next, in order to allow the baffle 280 to slide and be fixed on the baffle groove 230, the baffle 280 is divided into a front plate and a rear plate, the front plate can slide up and down on the inner wall of the baffle groove 230, the rear plate is fixed to the top of the water injection groove 220 by welding, and the side wall of the rear plate is connected with a bolt through a hinge. After the front plate is raised, the bolt is lowered to fix and support the front plate. Specifically, the baffle 280 is divided into a front plate and a rear plate, the front plate can slide up and down in the baffle groove 230, and the rear plate is fixed to the top of the water injection groove 220. A bolt is provided on the top of the front plate to fix the front plate when it is raised.

[0037] Finally, in order to maintain the stability of the motor 310 during operation, a motor frame 320 is fixedly connected to the inner wall of the working chamber 120 by screws, and the motor 310 is fixedly connected to the top of the motor frame 320 by screws. Specifically, a motor frame 320 is provided on the inner wall of the working chamber 120, and the motor 310 is connected to the top of the motor frame 320 to provide support for the motor 310 and maintain stable operation.
