Description

Technical Field

[0001] This utility model relates to the field of slag powder treatment technology, and in particular to a collection and conveying device for slag powder. Background Technology

[0002] Slag powder is a fine powder material made from slag through grinding. Slag itself is a by-product of the steel and casting industries, also known as steel slag or cast steel slag. After the slag is melted at high temperature and cooled, it is ground into fine powder, which is slag powder. Slag powder is an environmentally friendly and energy-saving industrial by-product. Reusing it can reduce resource waste and it is widely used in construction engineering. During the production process, some slag powder will be dispersed into the air and needs to be collected and transported to a designated location. Generally, collection and conveying devices are used, but most existing slag powder collection and conveying devices still have problems that need to be solved.

[0003] Most existing slag powder collection and conveying devices cannot screen the slag powder after collection. Slag powder of different particle sizes performs differently in different applications. Unsorted powder cannot achieve its maximum performance, resulting in resource waste. Unsorting also affects the process effect and the performance of the final product. Therefore, it is necessary to design a slag powder collection and conveying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a collection and conveying device for slag powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slag powder collection and conveying device includes an outer tank, an intermediate tank inside the outer tank, and an inner tank inside the intermediate tank. Two fixing frames are provided between the intermediate and inner tanks, and between the outer and intermediate tanks, respectively. These fixing frames are fixedly connected to the outer, intermediate, and inner tanks. Both the intermediate and inner tanks have sieve holes, with the sieve holes on the intermediate tank having a smaller diameter than those on the inner tank. Circular plates are provided on both sides of the outer tank, and limiting plates are fitted onto these circular plates. The circular plates are rotatably connected to the limiting plates, which are fixedly connected to the outer tanks. A blower is fixedly connected to one side of one of the outer tanks. Three valves are fixedly connected to the circular plate away from the blower. Flexible hoses are fixedly connected to the output ends of the three valves, and screw conveyors are fixedly connected to the output ends of the three flexible hoses. Due to the use of… This invention employs a rotating intermediate tank and inner tank for slag powder screening. During the rotation of these tanks, slag powder of different particle sizes passes through the screen openings for screening. The rotation also prevents slag powder from accumulating on the inner walls of the intermediate and inner tanks, effectively preventing screen blockage. This effectively solves the problems raised in the background section where most existing slag powder collection and conveying devices cannot screen the collected slag powder, resulting in different particle sizes exhibiting different performance characteristics in different applications. Unclassified powder cannot achieve its maximum performance, leading to resource waste and affecting process efficiency and final product performance. Therefore, this invention achieves effective slag powder screening and particle size classification, improves slag powder quality control, prevents slag powder accumulation on the tank walls, avoids screen blockage, and increases screening efficiency.

[0007] Preferably, the three screw conveyors are fixedly connected to the same support frame.

[0008] Preferably, a base is fixedly connected to one side of the support frame, and two fixing plates are fixedly connected to the top of one end of the base. Both fixing plates are rotatably connected to a fixing shaft, and the two fixing shafts are fixedly connected to the same circular plate.

[0009] Preferably, the base has a hydraulic telescopic rod fixedly connected to the top of the end away from the fixed plate.

[0010] Preferably, the telescopic end of the hydraulic telescopic rod is fixedly connected to a U-shaped plate, and the inner walls of both sides of the U-shaped plate are fixedly connected to the same sliding rod. The sliding rod is fitted with a straight plate, and a straight groove is opened on the straight plate. The sliding rod is set in the straight groove, and the straight plate is fixedly connected to a circular plate away from the fixed axis.

[0011] Preferably, a toothed ring is fixedly connected to the outer wall of the outer tank, and a gear is meshed with the toothed ring. A motor is provided on one side of the gear, and the output end of the motor is connected to the gear through a coupling. The motor is fixedly connected to a bracket, and one of the limiting plates is fixedly connected to the bracket.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing a rotating intermediate tank and inner tank for slag powder screening, slag powder of different particle sizes passes through the screen holes during the rotation process. The rotation of the intermediate and inner tanks also prevents slag powder from accumulating on their inner walls, effectively preventing screen blockage. This effectively solves the problems raised in the background section where most existing slag powder collection and conveying devices cannot screen the collected slag powder, resulting in different particle sizes exhibiting different performance characteristics in different applications. Unclassified powder cannot achieve its maximum performance, leading to resource waste and affecting process efficiency and final product performance. Therefore, this technology achieves effective slag powder screening and particle size classification, improves slag powder quality control, prevents slag powder accumulation on the tank walls, avoids screen blockage, and increases screening efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 A slag powder collection and conveying device includes an outer tank 1, an intermediate tank 2 inside the outer tank 1, and an inner tank 3 inside the intermediate tank 2. Two fixing frames 4 are provided between the intermediate tank 2 and the inner tank 3, and between the outer tank 1 and the intermediate tank 2. The fixing frames 4 are fixedly connected to the outer tank 1, the intermediate tank 2, and the inner tank 3. Screen holes 5 are provided on both the intermediate tank 2 and the inner tank 3. The aperture of the screen holes 5 on the intermediate tank 2 is smaller than that on the inner tank 3. Circular plates 6 are provided on both sides of the outer tank 1. Limiting plates 7 are fitted onto the circular plates 6. The circular plates 6 are rotatably connected to the limiting plates 7, and the limiting plates 7 are fixedly connected to the outer tank 1. A blower 8 is fixedly connected to one side of one of the outer tanks 1. Three valves 9 are fixedly connected to the circular plate 6 away from the blower 8. Flexible hoses 10 are fixedly connected to the output ends of the three valves 9, and screw conveyors are fixedly connected to the output ends of the three flexible hoses 10. Machine 11, by employing a rotating intermediate tank and inner tank for slag powder screening, allows slag powder of different particle sizes to pass through the screen holes during the rotation of the intermediate and inner tanks. The rotation of the intermediate and inner tanks also prevents slag powder from accumulating on their inner walls, effectively preventing screen blockage. This effectively solves the problems mentioned in the background art, where most existing slag powder collection and conveying devices cannot screen the collected slag powder, resulting in different particle sizes exhibiting different performance in different applications. Unclassified powder cannot achieve its maximum performance, leading to resource waste, and unclassified powder also affects process efficiency and final product performance. Therefore, it achieves effective slag powder screening and particle size classification, improves slag powder quality control, prevents slag powder accumulation on the tank walls, avoids screen blockage, and improves screening efficiency.

[0022] In this utility model, three screw conveyors 11 are fixedly connected to the same support frame 12.

[0023] In this utility model, a base 13 is fixedly connected to one side of the support frame 12, and two fixing plates 14 are fixedly connected to the top of one end of the base 13. Both fixing plates 14 are rotatably connected to a fixing shaft 15. The two fixing shafts 15 are fixedly connected to the same circular plate 6. When the outer tank 1 is tilted, it will rotate with the intersection of the fixing shaft 15 and the fixing plate 14 as the center, causing the outer tank 1 to tilt.

[0024] In this utility model, a hydraulic telescopic rod 16 is fixedly connected to the top of the base 13 at the end away from the fixed plate 14.

[0025] In this utility model, the telescopic end of the hydraulic telescopic rod 16 is fixedly connected to a U-shaped plate 17. The inner walls of both sides of the U-shaped plate 17 are fixedly connected to the same sliding rod 18. The sliding rod 18 is fitted with a straight plate 19. A straight groove 20 is opened on the straight plate 19. The sliding rod 18 is set in the straight groove 20. The straight plate 19 is fixedly connected to a circular plate 6 away from the fixed shaft 15. The hydraulic telescopic rod 16 is driven by an external hydraulic system to extend the telescopic end of the hydraulic telescopic rod 16, which can raise the U-shaped plate 17. The U-shaped plate 17 drives the sliding rod 18 to move in the straight groove 20, which can tilt the straight plate 19, thereby tilting the outer tank 1 and pouring out the slag powder in the outer tank 1, the middle tank 2 and the inner tank 3.

[0026] In this utility model, a toothed ring 21 is fixedly connected to the outer wall of the outer tank 1, and a gear 22 is meshed with the toothed ring 21. A motor 24 is provided on one side of the gear 22. The output end of the motor 24 is connected to the gear 22 through a coupling. The motor 24 is fixedly connected to a bracket 23, and one of the limiting plates 7 is fixedly connected to the bracket 23.

[0027] Working principle: When in use, an external power supply is used. The blower 8 and motor 24 are started via an external controller. The blower 8 draws the slag powder into the inner tank 3 for collection. The output of the motor 24 drives the coupling to rotate, which in turn drives the gear 22. The gear 22 then drives the gear ring 21, which in turn drives the outer tank 1 to rotate. Connected by the fixing frame 4, the rotation of the outer tank 1 causes both the middle tank 2 and the inner tank 3 to rotate, thus agitating the slag powder inside for screening. After screening, the extension end of the hydraulic telescopic rod 16 extends, causing the U-shaped plate 17 to move upwards. When the U-shaped plate 17 is raised, it will drive the slide bar 18 to rise. The slide bar 18 will drive the straight plate 19 to gradually tilt. The slide bar 18 will move within the straight groove 20. The tilting of the straight plate 19 will drive the circular plate 6 to tilt. The circular plate 6 will drive the limiting plate 7 to tilt. The limiting plate 7 will drive the outer tank 1 to tilt. This will allow the outer tank 1, the middle tank 2, and the inner tank 3 to all tilt. The valve 9 will be opened to pour out the slag powder that has been screened in the outer tank 1, the middle tank 2, and the inner tank 3. The powder will be injected into the screw conveyor 11 through the hose 10. The drive motor of the screw conveyor 11 will be started to make the screw conveyor 11 work to transport the slag powder.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
