Description

Technical Field

[0001] This utility model belongs to the field of slag incineration treatment technology, specifically relating to an adjustable feeding and equalization mechanism for slag incineration treatment equipment. Background Technology

[0002] Slag incineration equipment is a specialized set of equipment for the secondary incineration, harmless treatment, and resource utilization of slag generated after the incineration of industrial solid waste and municipal solid waste. Its core purpose is to completely decompose the residual combustible components in the slag and remove harmful pollutants. Simultaneously, it recovers metal resources through processes such as screening and magnetic separation, ultimately achieving the environmentally friendly treatment goals of slag reduction, harmlessness, and resource recovery. It is widely used in the solid waste treatment industry.

[0003] Specifically, in the process of secondary incineration and harmless treatment of slag using slag incineration equipment, if a one-time centralized feeding mode is adopted, a large amount of slag will instantly accumulate in the incineration furnace. This not only leads to the slag particles being tightly packed together with insufficient gaps, preventing oxygen from the ventilation system from penetrating evenly to the deeper layers of the material, but also causes the slag at the bottom and middle parts to fail to burn completely due to lack of oxygen, leaving behind a large amount of combustible components and harmful organic matter, reducing the volume reduction and harmless treatment effect; it also causes a sudden drop in furnace temperature due to excessive accumulation of material in some areas, disrupting the stability of combustion conditions and even posing a risk of flameout. At the same time, one-time feeding easily causes blockage of the feeding channel and slag bridging and clumping, requiring subsequent shutdown for cleaning, affecting the continuous operation of the equipment, and the incompletely burned slag will also increase the difficulty of subsequent sorting and processing, reducing the efficiency of metal resource recovery. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable feeding and equalization mechanism for slag incineration treatment equipment. This addresses the problem that when using a centralized, one-time feeding method for secondary incineration of slag for harmless treatment, a large amount of slag will instantly accumulate in the incineration furnace. This not only leads to tight adhesion and insufficient gaps between slag particles, preventing the oxygen supplied by the ventilation system from evenly penetrating to the deeper layers of the material, but also results in insufficient combustion of the slag at the bottom and middle sections due to oxygen deficiency, leaving behind a large amount of combustible components and harmful organic matter, thus reducing the volume reduction and harmless treatment effect; it also causes a sudden drop in furnace temperature due to excessive local material accumulation, disrupting the stability of combustion conditions and even posing a risk of flameout.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable feeding and equalization mechanism for a slag incineration treatment device, comprising a support and a feeding box installed on the surface of the support, a controller installed on one side of the feeding box, a crushing chamber installed on the top of the feeding box, a discharge bin installed on the bottom of the crushing chamber, and a feeding port installed on one side of the top of the crushing chamber.

[0006] A conveyor is installed inside the feed box. A drive motor is installed on the back side of the feed box near the conveyor.

A threaded screw is threaded through the surface of the feed box near the outlet end. A receiving block is rotatably connected to the bottom end of the threaded screw. A material leveling scraper is connected to the bottom surface of the receiving block. A guide rod is connected to the surface of the material leveling scraper.

[0007] To facilitate and ensure stable movement of the uniform scraper, the adjustable feeding and uniform mechanism of the slag incineration treatment equipment of this utility model preferably has two guide rods. The guide rods pass through and extend to the outside of the feeding box, and the guide rods and the feeding box form a sliding guide structure.

[0008] In order to crush the slag, as an adjustable feeding and equalizing mechanism of the slag incineration treatment equipment of this utility model, preferably, a crushing motor is installed on the outer surface of the crushing chamber, the output end of the crushing motor is connected to a crushing roller, the other end of the crushing roller is connected to a linkage gear, and two sets of crushing rollers are provided.

[0009] To facilitate the stable movement of the flow regulating plate, as an adjustable feeding and equalizing mechanism for the slag incineration treatment equipment of this utility model, preferably, a positioning frame is connected to the surface of the crushing chamber near the feed inlet, and a limit plate is connected to one side of the positioning frame, the limit plate having an L-shaped cross-section.

[0010] To enable automatic adjustment, in the adjustable feeding and equalization mechanism of the slag incineration treatment equipment of this utility model, preferably, a cylinder box is installed at the top of one side of the positioning frame relative to the limiting plate, and a telescopic cylinder is installed inside the cylinder box, and the telescopic cylinder is electrically connected to the controller.

[0011] To facilitate adjustment of the feed rate, in the adjustable feeding and equalization mechanism of the slag incineration treatment equipment of this utility model, preferably, the inner wall of the limiting plate is slidably connected to a flow regulating plate, and the top and bottom surfaces of the flow regulating plate are connected to the telescopic cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves crushing slag waste in a crushing chamber, then feeding the crushed slag into a feed box, which simultaneously drives a conveyor inside the feed box. The crushed slag falls between two partitions on the surface of the conveyor belt. At this point, the screw is rotated, causing the uniform scraper at the bottom of the screw to adjust its height. As the conveyor belt rotates, the uniform scraper scrapes the excess slag between the partitions, achieving uniform material conveying. The slag then falls into the incineration furnace for incineration, improving the slag incineration effect, achieving complete combustion, and ensuring a continuous furnace temperature.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 The present invention provides the following technical solution: an adjustable feeding and equalization mechanism for a slag incineration treatment equipment, including a support 1 and a feeding box 2 installed on the surface of the support 1, a controller 3 installed on one side of the feeding box 2, a crushing chamber 4 installed on the top of the feeding box 2, a discharge chamber 5 installed on the bottom surface of the crushing chamber 4, and a feeding port 6 installed on one side of the top of the crushing chamber 4.

[0025] A conveyor 7 is installed inside the feed box 2. A drive motor 8 is installed on the back side of the feed box 2 near the conveyor 7. A conveyor belt 9 is connected to the inner drive roller surface of the conveyor 7. A partition plate 10 is connected to the surface of the conveyor belt 9. A threaded screw 11 is threaded through the surface of the feed box 2 near the outlet end. A receiving block 12 is rotatably connected to the bottom end of the threaded screw 11. A material leveling scraper 13 is connected to the bottom surface of the receiving block 12. A guide rod 14 is connected to the surface of the material leveling scraper 13.

[0026] Preferably, two guide rods 14 are provided, which pass through and extend to the outside of the feed box 2, forming a sliding guide structure with the feed box 2. In actual use, by sliding the guide rods 14 along the opening on the surface of the feed box 2, it is convenient to drive the uniform scraper 13 to move in a specific direction.

[0027] Preferably, a crushing motor 15 is installed on the outer surface of the crushing chamber 4. The output end of the crushing motor 15 is connected to a crushing roller 16, and the other end of the crushing roller 16 is connected to a linkage gear 17. Two sets of crushing rollers 16 are provided. In actual use, the crushing motor 15 is controlled to drive the two sets of crushing rollers 16 to rotate, so that the slag is fully crushed.

[0028] Preferably, a positioning frame 18 is connected to the surface of the crushing chamber 4 near the feed inlet 6, and a limiting plate 19 is connected to one side of the positioning frame 18. The limiting plate 19 has an L-shaped cross section.

[0029] Preferably, a cylinder box 20 is installed on the top of one side of the positioning frame 18 relative to the limiting plate 19, and a telescopic cylinder 21 is installed inside the cylinder box 20. The telescopic cylinder 21 is electrically connected to the controller 3.

[0030] Preferably, a flow regulating plate 22 is slidably connected to the inner wall of the limiting plate 19, and the top and bottom surfaces of the flow regulating plate 22 are connected to the telescopic cylinder 21. In actual use, by driving the telescopic cylinder 21 inside the cylinder box 20, the output end of the telescopic cylinder 21 drives the flow regulating plate 22 to slide up and down along the limiting plate 19, thereby adjusting the inlet size of the feed port 6. At this time, it is convenient to adjust the feed amount at any time according to the slag crushing situation, ensuring that the slag is fully crushed, which is convenient for subsequent incineration. It is worth noting that a capacitive material level sensor is installed on the inner wall of the crushing chamber 4. Utilizing the difference in dielectric constant between the material and air, when the slag contacts or approaches the sensor probe, the capacitance value changes, which determines whether the material has reached the set height and controls the opening amount of the flow regulating plate 22.

[0031] The working principle of this utility model is as follows: First, the slag waste is poured into the crushing bin 4 for crushing. The crushed slag then enters the feeding box 2, and the conveyor 7 inside the feeding box 2 is driven. At this time, the crushed slag falls between the two partitions 10 on the surface of the conveyor belt 9. Then, the threaded screw 11 is rotated, which drives the uniform scraper 13 at the bottom of the threaded screw 11 to adjust its height. At the same time, the guide rod 14 on the surface of the uniform scraper 13 slides along the opening on the surface of the feeding box 2 to ensure the stable directional movement of the uniform scraper 13. When the conveyor belt 9 rotates, the uniform scraper 13 scrapes the excess slag between the partitions 10 to achieve uniform material conveying. The slag then falls into the incineration furnace for incineration, which improves the slag incineration effect, achieves complete combustion, and ensures the continuous temperature of the furnace.

[0032] It is worth noting that the speed of conveyor 7 can be adjusted at any time according to the combustion effect in the furnace to ensure uniform feeding. Temperature sensors are used for detection throughout the process.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
