Description

Technical Field

[0001] The invention relates to the technical field of slag cleaning robots, and in particular to a slag cleaning robot in a gas furnace. Background Art

[0002] In existing industrial production, gas furnaces are important heating equipment and are widely used in many fields such as metal smelting, ceramic firing, chemical reactions, etc. However, with the continuous operation of the gas furnace, a large amount of slag and residue will inevitably be produced in the furnace. If these impurities are not cleaned in time, they will not only reduce the thermal efficiency of the gas furnace, but also may cause damage to the gas furnace itself and its ancillary equipment, and even cause safety accidents. Therefore, regular slag cleaning of gas furnaces is a key link to ensure production safety and improve production efficiency.

[0003] With the advancement of science and technology and the development of industry, some automatic slag cleaning equipment have appeared on the market. However, in practical applications, the adaptability of these automatic slag cleaning equipment is generally poor, and the adsorption force is limited in high temperature environments, making it difficult to stably adsorb on the inner wall of the gas furnace. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides a slag cleaning robot in a gas furnace, which can improve the stability of adsorption.

[0005] To achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows:

[0006] A slag cleaning robot in a gas furnace comprises a tracked vehicle, a crushing head, an adsorption hood, an inner pipe, an outer pipe, a cooling box and an air pump, wherein the front end of the tracked vehicle is provided with a crushing head, the bottom of the tracked vehicle is provided with an adsorption hood, the adsorption hood comprises a lower cover body and an upper cover body, the lower cover body constitutes an adsorption chamber, an annular air outlet end is formed between the upper cover body and the lower cover body, the diameter of the upper cover body is smaller than the diameter of the lower cover body, the adsorption chamber is communicated with the inner pipe, the inner pipe is sleeved in the outer pipe, the inner pipe is communicated with the cooling box, the cooling box is connected to the air inlet of the air pump, the air outlet of the air pump is communicated with the outer pipe, and the outer pipe is communicated with the air outlet end.

[0007] Furthermore, the lower cover body is provided with a convex ring on the upper surface of the outer edge, and the convex ring is provided with a groove on the side facing the center, and the groove is tangent to the upper surface of the lower cover body.

[0008] Furthermore, the lower cover body includes a rigid part and a flexible part, the rigid part is located at the center of the lower cover body, the flexible part is located at the edge of the lower cover body, the convex ring is arranged at the edge of the flexible part, and the convex ring is elastic.

[0009] Furthermore, a plurality of first magnets are arranged at intervals in the convex ring, the magnetic poles of the first magnets are facing the adsorption surface, the first magnets and the second magnets repel each other, the second magnets are fixed on a moving vehicle outside the gas furnace, the moving vehicle is provided with a third magnet for attracting the tracked vehicle, and the moving vehicle moves synchronously with the tracked vehicle.

[0010] Furthermore, the mobile vehicle includes a frame and universal wheels, the universal wheels are mounted on the frame, and the universal wheels are used to move along the side wall of the gas furnace.

[0011] Furthermore, a telescopic rod is provided at the bottom of the crawler vehicle, the telescopic rod is connected to the adsorption cover, and the telescopic rod is used to drive the adsorption cover to move up and down.

[0012] Furthermore, the inner pipe is connected to the upper end of the first bellows, the lower end of the first bellows is connected to the lower cover body, the outer pipe is connected to the upper end of the second bellows, and the lower end of the second bellows is connected to the upper cover body.

[0014] Furthermore, a lighting lamp is provided in front of the crawler vehicle.

[0015] Furthermore, a mechanical arm is provided in front of the crawler vehicle, and the crushing head is installed on the mechanical arm.

[0016] The beneficial effects of the present invention are:

[0017] (1) The gas is cooled by a cooling box. The density of the gas increases after the temperature is lowered. The air pump can then extract more gas, thereby improving the efficiency of the gas extraction. This allows a greater negative pressure to be formed at the bottom of the lower cover, which is beneficial for the crawler vehicle to be adsorbed on the inner wall of the gas furnace.

[0018] (2) After the air pump draws out the air, it flows back to the air outlet between the upper cover body and the lower cover body through the external pipe, so that the gas discharged from the air outlet cools the surrounding of the adsorption cover, reducing the temperature around the adsorption cover, that is, the low-temperature airflow flows from the top of the adsorption cover, and the high-temperature air flows from the bottom of the adsorption cover. The low-temperature gas pressure increases the air pressure around the adsorption cover, and the adsorption cover is adsorbed on the inner wall of the gas furnace under the action of the pressure difference. On the other hand, under the action of the air pump, the gas under the adsorption cover is drawn out, which reduces the pressure under the adsorption cover and also promotes the adsorption cover to be adsorbed on the inner wall of the gas furnace.

[0019] (3) The present invention can move at the bottom of the gas furnace or along the side wall of the gas furnace. When the crusher moves to the position where slag cleaning is required, the crushing head is used to clean the slag. The present invention can be adapted to higher temperature gas furnaces and can stably move at the bottom and side of the gas furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element.

[0028] Please refer to the attached Figures 1-2 The present application provides a slag cleaning robot in a gas furnace, comprising a crawler vehicle 1, a crushing head 2, an adsorption hood 3, an inner pipe 4, an outer pipe 5, a cooling box 6 and an air pump 7. The front end of the crawler vehicle 1 is provided with a crushing head 2, and the bottom of the crawler vehicle 1 is provided with an adsorption hood 3, the adsorption hood 3 comprises a lower cover body 8 and an upper cover body 9, the lower cover body 8 constitutes an adsorption chamber 10, an annular gas outlet end 11 is formed between the upper cover body 9 and the lower cover body 8, the diameter of the upper cover body 9 is smaller than the diameter of the lower cover body 8, the gas coming out of the gas outlet end 11 is blown to the back of the lower cover body 8, the adsorption chamber 10 is communicated with the inner pipe 4, the inner pipe 4 is sleeved in the outer pipe 5, the inner pipe 4 is communicated with the cooling box 6, the cooling box 6 is connected to the air inlet of the air pump 7, the air outlet of the air pump 7 is communicated with the outer pipe 5, and the outer pipe 5 is communicated with the gas outlet end 11.

[0029] The cooling box 6 is used to cool the gas. The density of the gas increases after the temperature is reduced. The air pump 7 can extract more gas when extracting the gas, thereby improving the efficiency of the gas extraction, thereby forming a larger negative pressure at the bottom of the lower cover 8, which is conducive to the adsorption of the tracked vehicle 1 on the inner wall of the gas furnace.

[0030] After the air pump 7 draws out the air, it flows back to the outlet port 11 between the upper cover body 9 and the lower cover body 8 through the outer pipe 5, so that the gas discharged from the outlet port 11 cools the surrounding of the adsorption cover 3, so that the temperature around the adsorption cover 3 is reduced, that is, the low-temperature airflow flows through the top of the adsorption cover 3, and the high-temperature air flows through the bottom of the adsorption cover 3. The low-temperature gas pressure increases the air pressure around the adsorption cover 3, and the adsorption cover 3 is adsorbed on the inner wall of the gas furnace under the action of the pressure difference. On the other hand, under the action of the air pump 7, the gas below the adsorption cover 3 is drawn out, so that the pressure below the adsorption cover 3 is reduced, which also promotes the adsorption cover 3 to be adsorbed on the inner wall of the gas furnace.

[0031] The present invention can move at the bottom of the gas furnace or along the side wall of the gas furnace. When the crushing head 2 is used to clean the slag at the position where slag cleaning is required, the crushing head 2 can be used to adapt to higher temperature gas furnaces and can stably move at the bottom and side of the gas furnace.

[0032] Specifically, the lower cover body 8 is provided with a convex ring 12 on the upper surface of the outer edge, and the convex ring 12 is provided with a groove 13 on the side facing the center, and the groove 13 is tangent to the upper surface of the lower cover body 8. When the gas is discharged from the outlet end, the gas impacts the convex ring 12, pushing the convex ring 12 to move in the direction of the adsorption surface, and at the same time, turbulence occurs at the connection between the convex ring 12 and the inner side of the lower cover body 8, thereby increasing the gas pressure at the edge of the lower cover body 8 and promoting the lower cover body 8 to be adsorbed on the inner wall of the gas furnace.

[0033] See also Figure 3 In some optional embodiments, the lower cover body 8 includes a rigid portion 14 and a flexible portion 15, wherein the rigid portion 14 is located at the center of the lower cover body 8, and the flexible portion 15 is located at the edge of the lower cover body 8. Optionally, the convex ring 12 is provided at the edge of the flexible portion 15, and the convex ring 12 is elastic. The flexible portion 15 can deform accordingly with the shape of the inner wall of the gas furnace, thereby increasing the resistance of the gas entering the lower cover body 8, thereby improving the adsorption stability. When the gas impacts the convex ring 12, the convex ring 12 is pushed to deform in the direction of the adsorption surface, thereby increasing the resistance of the gas entering the lower cover body 8, thereby improving the adsorption stability.

[0034] See also Figure 3 In some optional embodiments, a plurality of first magnets 16 are arranged at intervals in the convex ring 12, the magnetic poles of the first magnets 16 face the adsorption surface, the first magnets 16 and the second magnets 17 repel each other, the second magnets 17 are fixed on a moving vehicle 18 outside the gas furnace, the moving vehicle 18 is provided with a third magnet 19 for attracting the crawler vehicle 1, and the moving vehicle 18 moves synchronously with the crawler vehicle 1. Under the action of the third magnet 19, the moving vehicle 18 moves synchronously with the crawler vehicle 1. Since the moving vehicle 18 and the crawler vehicle 1 attract each other through magnetic force, the stability of the crawler vehicle 1 moving on the inner wall of the gas furnace can be improved. A plurality of first magnets 16 are arranged at intervals in the convex ring 12, with the magnetic poles of the first magnets 16 facing the adsorption surface, and the first magnets 16 and the second magnets 17 repel each other. The interaction between the first magnets 16 and the second magnets 17 can ensure that there is an air gap between the adsorption cover 3 and the gas furnace, thereby preventing the adsorption cover 3 from being sucked tightly on the gas furnace and preventing the opening of the adsorption cover 3 from being too large during the change from suction to separation, thereby preventing the tracked vehicle 1 from falling due to insufficient adsorption force, thereby facilitating the tracked vehicle 1 to move stably on the inner wall of the gas furnace.

[0035] Specifically, the mobile vehicle 18 includes a frame 20 and universal wheels 21, wherein the universal wheels 21 are mounted on the frame 20 and are used to move along the side wall of the gas furnace. The universal wheels 21 can rotate in multiple directions, so that the mobile vehicle 18 can move outside the gas furnace.

[0036] See also Figure 4In some optional embodiments, a telescopic rod 22 is provided at the bottom of the crawler vehicle 1, and the telescopic rod 22 is connected to the adsorption cover 3, and the telescopic rod 22 is used to drive the adsorption cover 3 to move up and down. The telescopic rod 22 is used to control the movement of the adsorption cover 3, thereby adjusting the position of the adsorption cover 3 to ensure that the adsorption cover 3 and the inner wall of the gas furnace are adsorbed stably.

[0037] Specifically, the inner pipe 4 is connected to the upper end of the first bellows 23, the lower end of the first bellows 23 is connected to the lower cover 8, the outer pipe 5 is connected to the upper end of the second bellows 24, and the lower end of the second bellows 24 is connected to the upper cover 9. By connecting the lower cover 8 and the upper cover 9 with the first bellows 23 and the second bellows 24, the lower cover 8 and the upper cover 9 can be deformed according to the lifting and lowering of the lower cover 8 and the upper cover 9, thereby improving applicability.

[0038] Specifically, the telescopic rod 22 is an electric telescopic rod 22. By electrically controlling the telescopic rod 22 to extend and retract, the telescopic rod 22 can work stably under the condition of large temperature changes.

[0039] Specifically, a lighting lamp 25 is provided in front of the crawler vehicle 1. The lighting lamp 25 is used for lighting to facilitate the slag removal operation.

[0040] Specifically, a mechanical arm 26 is provided in front of the crawler vehicle 1, and the crushing head 2 is mounted on the mechanical arm 26. The crushing head 2 is adjusted by the mechanical arm 26 to perform slag removal operations.

[0041] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
