Description

Technical Field

[0001] This utility model relates to the field of blast furnace cleaning technology, and in particular to a cleaning device for blast furnace slag trenches. Background Technology

[0002] Blast furnace slag is a type of waste slag discharged from the blast furnace during iron and steel smelting. Blast furnace slag is divided into upper slag and lower slag. Upper slag is actively discharged through the slag outlet on the side of the blast furnace, while lower slag is discharged along with the molten iron and transported directionally through slag channels. Over long-term use, the lower slag gradually accumulates and hardens at the bottom and side walls of the slag channels, causing the flow channels to narrow and eventually become blocked, affecting slag discharge.

[0003] Patent document CN 219385195U discloses a blast furnace slag ditch cleaning device, which includes two support legs. A fixed box is fixedly installed at the top of the two support legs. A rotating rod is rotatably installed inside the fixed box, and one end of the rotating rod extends outside the fixed box. A rotating motor is fixedly installed on one outer wall of the fixed box, and the output shaft of the rotating motor is fixedly connected to the end of the rotating rod located outside the fixed box. Two winding wheels are fixedly sleeved on the rotating rod, and pull ropes are wound on the two winding wheels respectively. The bottom ends of the two pull ropes extend to the bottom of the fixed box.

[0004] When implementing the above-mentioned patented technology, the inventors discovered the following problems:

[0005] 1. The cleaning device cannot move on its own. After cleaning one area, a crane is needed to move the cleaning device to the next area, which makes the cleaning work very cumbersome and time-consuming.

[0006] 2. When workers are cleaning, they need to hold the electric pick and overcome the elasticity of the spring rope to move the electric pick to the area that needs to be cleaned in the slag ditch. Long-term high-intensity work can easily cause worker fatigue. The cleaning device has no fixed mechanism and there is a risk of tipping over due to the pulling of the spring rope.

[0057] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0058] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0059] This embodiment provides a cleaning device 100 for blast furnace slag channels, used to clean the slag channels of blast furnaces, so as to reduce and shorten the labor intensity and working time of workers and ensure operational safety. Figure 1 This is a three-dimensional structural diagram of the cleaning device 100, which mainly consists of three parts: a drive mechanism 200, a crushing mechanism 300, and a dust removal mechanism 400. The crushing mechanism 300 is installed at the front end above the drive mechanism 200, and the dust removal mechanism 400 is installed behind the crushing mechanism 300. The crushing mechanism 300 uses an electric pick 306 to crush the slag deposited in the slag trench, while the dust removal mechanism 400 uses an air pump 403 to absorb the dust raised during the crushing of the slag, ensuring a clean working environment for the workers. The drive mechanism 200 moves back and forth via a motor 210, thereby driving the crushing mechanism 300 and the dust removal mechanism 400 to move forward and backward in the slag trench and clean the slag trench passage.

[0060] Figure 2 This is a cross-sectional schematic diagram of the drive mechanism 200 of the cleaning device 100. As shown in the figure, the drive mechanism 200 mainly includes a base frame 201, a water tank 202, a one-way valve 203, a water injection pipe 204, a hydraulic cylinder 205, a bracket 206, a drive wheel 207, a drain pipe 208, a switch valve 209, and a motor 210. The water tank 202 is installed at one end above the base frame 201. A U-shaped notch 2011 is opened at the other end of the base frame 201, opposite to the water tank 202. A fixing hole 2014 is opened on the base frame 201 between the water tank 202 and the U-shaped notch 2011. The one-way valve 203 is installed on the side wall of the water tank 202 near the bottom of the water tank 202 and facing the U-shaped notch 2011. The base frame 201 has threaded holes 2012 around its perimeter. The base frame 201 is connected to the lifting ring through the threaded holes 2012, and the cleaning device 100 is lifted into the slag passage through the lifting ring.

[0061] A flange is formed on one end of the water injection pipe 204. The flange has several through holes arranged in a ring. The water injection pipe 204 is bolted to the top of the water tank 202. A sealing gasket is installed between the flange and the top of the water tank 202 to prevent water leakage from the gap between the water tank 202 and the water injection pipe 204. The switch valve 209 is installed below the base frame 201 and below the water tank 202. A drain pipe 208 is installed below the switch valve 209. The drain pipe 208 passes through the switch valve 209 and the base frame 201 and is inserted into the interior of the water tank 202, flush with the inner surface of the bottom of the water tank 202.

[0062] A base 2013 is formed on the front and rear sides below the base frame 201. Hydraulic cylinders 205 are fixedly mounted at both ends of the base 2013. A bracket 206 is fixedly mounted at the bottom end of the hydraulic cylinders 205. A drive wheel 207 is mounted inside the bracket 206 via a pin, and the drive wheel 207 is connected to the pin via a key. A motor 210 is fixedly mounted on the outside of the bracket 206, and its output shaft is fixedly connected to the pin. Thus, the rotation of the motor 210's output shaft causes the drive wheel 207 to rotate synchronously, thereby driving the cleaning device 100 to move. The forward and reverse rotation of the motor 210 causes the cleaning device 100 to move forward and backward. The height of the drive mechanism 200 is adjusted by extending and retracting the hydraulic cylinders 205, thereby adjusting the height of the cleaning device 100 and improving its ability to overcome obstacles.

[0063] The three-dimensional structure of the crushing mechanism 300 is as follows: Figure 3 As shown, the crushing mechanism 300 is installed at the U-shaped notch 2011 above the base frame 201. The crushing mechanism 300 mainly consists of a support frame 301, a first guide rail 302, a first slider 303, a second guide rail 304, a second slider 305, and an electric pick 306. The support frame 301 is U-shaped, with columns 3011 formed around its perimeter. Threaded holes are machined at the top of the columns 3011, and countersunk holes are machined on the first guide rail 302. The first guide rail 302 is then bolted to the columns 3011. The first guide rail 302 is installed on the columns 3011 on both the left and right sides. The first slider 303 is slidably connected above the first guide rail 302. A second guide rail 304 extending in the left-right direction is provided on the top of the first slider 303. The second slider 305 is slidably connected below the second guide rail 304. The electric pick 306 is fixedly connected below the second slider 305. Therefore, by sliding the first slider 303 back and forth on the first guide rail 302, the second guide rail 304 is moved in the back-and-forth direction, thereby causing the electric pick 306 to move back and forth. By sliding the second slider 305 left and right on the second guide rail 304, the electric pick 306 is moved left and right. The superposition of the two movements can satisfy the working conditions of the electric pick 306 in any direction.

[0064] Figure 4This is a three-dimensional structural diagram of the dust removal mechanism 400 in the cleaning device 100. As shown, the dust removal mechanism 400 mainly includes a dust suction hood 401, an air inlet pipe 402, an air pump 403, and an exhaust pipe 404. The air pump 403 is installed above the base frame 201 and located between the U-shaped notch 2011 and the water tank 202. One end of the air pump 403 is fixedly connected to the exhaust pipe 404. A flange is formed in the circumferential direction of the exhaust pipe 404, and through holes arranged in a ring array are machined on the flange. The exhaust pipe 404 is connected to the one-way valve 203 on the water tank 202 through the flange. A sealing gasket is installed between the flange and the one-way valve 203 to prevent air leakage from the gap between the flange and the one-way valve 203. One end of the air intake pipe 402 passes through the fixing hole 2014 on the base frame 201 and is fixedly connected to the air pump 403. The other end is located below the base frame 201 and is connected to a dust suction hood 401, which is located near the lower end of the electric hammer 306. Thus, the dust generated when the electric hammer 306 crushes slag is sucked into the air pump 403 through the air intake pipe 402 and the dust suction hood 401, and then discharged into the water tank 202 through the exhaust pipe 404. The dust carried in the gas combines with the clean water and remains in the water tank 202, thereby achieving dust removal.

[0065] When using the blast furnace slag trough cleaning device 100, first connect the water injection pipe 204 to an external water source and inject clean water into the water tank 202. After filling the tank, disconnect the water injection pipe 204 from the external water source. The water tank 202, filled with water, acts as a counterweight for the cleaning device 100, making the device more stable and safer during operation. Using hoisting equipment, the cleaning device 100 is lifted into the slag trough using lifting rings. The cleaning device 100 is then remotely controlled via wired or wireless means. Subsequently, the electric pick 306, along with the first slider 303 and the second slider 305, is activated. The electric pick 306 breaks up the clumped slag, causing it to detach from the bottom and side walls of the slag trough. The first slider 303 and the second slider 305 slide on the guide rail, driving the electric pick 306 to break up the slag in any direction. Simultaneously, the air pump 403 is started. The air pump 403 sucks in the dust generated during the crushing of slag through the dust suction hood 401 and the air inlet pipe 402, and then discharges it into the water tank 202 through the exhaust pipe 404 and the one-way valve 203. The air carrying dust enters from the bottom of the water tank 202. The dust and clean water are combined and remain in the water tank 202. The air that has been cleaned of dust is discharged from the water tank 202 through the water injection pipe 204 at the top of the water tank 202. At this time, the water injection pipe 204 is not connected to an external water source, so the water injection pipe 204 becomes the air outlet pipe.

[0066] After the slag in the area where the cleaning device 100 is located is cleaned, the motor 210 is started. The output shaft of the motor 210 drives the drive wheel 207 to rotate, thereby moving the cleaning device 100 to the next area. When encountering slag in low-lying areas, the hydraulic cylinder 205 is activated. By extending and retracting the hydraulic cylinder 205, the height of the drive mechanism 200 can be adjusted, thus cleaning the slag in low-lying areas. The adjustment of the hydraulic cylinder 205 improves the adaptability and obstacle-crossing ability of the cleaning device 100.

[0067] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
