Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical machinery, in particular to a converter EC spray gun cleaning device. Background Art

[0002] Dry dust removal on steelmaking production lines in metallurgical enterprises utilizes an EC spray gun system, with the EC gun as the primary piece of equipment. The spray gun's head is an atomizing nozzle. In actual production, this nozzle is located at the top of the EC cylinder, a location characterized by high temperatures, high dust levels, and a harsh environment. Impurities, scale, and other debris, after being affected by high-temperature steam, often clog the nozzle. A clogged nozzle prevents water from flowing properly through the nozzle's inlet, resulting in insufficient water flow into the system, poor atomization, and ineffective cooling of the dust removal flue gas. This also leads to dust accumulation and agglomeration on the cylinder walls, necessitating regular furnace shutdowns, offline inspections, and cleaning of the nozzle.

[0003] There are three common methods for cleaning nozzles: manual mechanical cleaning with a chisel. However, due to the small nozzle aperture and the hardness of the clogged material, manual cleaning with a chisel is difficult and can easily damage the nozzle. Acidic chemical cleaning is ineffective due to the small contact area and inability to penetrate deeply into the nozzle. High-pressure water jet cleaning is also common. All three methods are performed offline, resulting in relatively high maintenance costs and the need for furnace downtime, which significantly impacts production and processing cycles. Currently, there is an urgent need for an effective and rapid cleaning method or device for nozzle cleaning. Therefore, a cleaning device for cleaning and repairing nozzles in converter EC spray gun systems is needed to address the high costs, low efficiency, and production delays associated with existing mechanical, chemical, and offline high-pressure cleaning methods for EC spray guns.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, a converter EC spray gun cleaning device includes a cylinder 3 and a high-pressure water gun 1. Six groups of spray guns 32 are installed inside the cylinder 3. The outer periphery of the cylinder 3 is provided with a cylinder wall 31. The cylinder wall 31 is provided with six mounting holes, and the spray guns 32 are installed in the mounting holes.

[0025] The spray gun 32 includes a spray gun head 41 and a spray gun barrel 42 . The spray gun barrel 42 passes through the mounting hole on the cylinder wall 31 . The spray gun barrel 42 is connected to the spray gun head 41 through a bend pipe. The spray gun head 41 faces the outlet of the cylinder 3 .

[0026] In actual production, the spray gun nozzle 41 and the spray gun barrel 42 are located in a high-temperature, dusty environment with relatively harsh conditions. Some impurities, scale flakes, etc. often clog the water inlet of the spray gun nozzle 41 after sintering, and the accumulated dust will accumulate above the spray gun barrel 42 and around the cylinder wall 31, causing dust accumulation in the cylinder. The smaller the cylinder diameter, the more smoke extraction effect of the dust removal system will be affected.

[0027] The high-pressure water gun 1 extends into the interior of the cylindrical body 3, and the water gun barrel 11 of the high-pressure water gun 1 is connected to the external high-pressure water pump. The water gun barrel 11 includes a hollow bolt 21, a tube body 22 and a nut 23. The hollow bolt 21 is fixedly set at the front of the tube body 22, and the nut 23 is fixedly set at the rear of the tube body 22. The tube bodies 22 are connected front and back through the hollow bolt 21 and the nut 23.

[0028] The high-pressure water gun 1 extends into the cylindrical body 3 through the mounting hole on the cylindrical body wall 31 , and the high-pressure water gun 1 sprays water to clean the spray gun nozzle 41 .

[0029] The hollow bolt 21 and the nut 23 are integrally formed and fixed to the tube body 22. The hollow bolt 21 is provided with an external thread, and the nut 23 is provided with an internal thread. The tube body 22 is connected at the head and tail by a thread. The nut of the tail end of the tube body 22 is threadedly connected to the water gun handle 12, and the tail of the water gun handle 12 is connected to the high-pressure water pump through a high-pressure water pipe.

[0030] The working principle of this utility model:

[0031] This utility model utilizes an adjustable high-pressure water gun 1. The gun 1 comprises a gun barrel 11, a gun handle 12, a gun barrel 2, a hollow bolt 21, a tube body 22, and a nut 23. The hollow bolt 21 and nut 23 are welded to the front and rear of the gun barrel 2. Depending on the diameter of the EC cylinder, a different number of gun barrels can be used. The rear end of the gun handle 12 is connected to a high-pressure water pump via a high-pressure water pipe.

[0032] When cleaning, disassemble one of the spray guns of the EC cylinder that needs to be cleaned. Figure 3 As shown, the water gun barrel 11 is then fixed with a hollow bolt 21 and a nut 23, the high-pressure water gun 1 is inserted into the cylinder wall 31, close to the spray gun nozzle 41, and the high-pressure water pump is turned on to use the high-pressure water gun 1 to deliver high-pressure water to impact the spray gun nozzle 41, so that impurities and other substances inside the spray gun nozzle 41 are impacted and fall to the bottom of the cylinder 3. In order to prevent the high-pressure water from splashing after being sprayed in the cylinder 3, the position of the high-pressure water gun 1 can be adjusted at any time to ensure that the sprayed water can flow along the inner wall of the cylinder 3 to the bottom.

[0033] The cleaning device of the present invention can utilize the impact of high-pressure water to clean the spray gun nozzle 41, while reducing the damage rate of the cleaning spare parts and improving the efficiency of simultaneously cleaning multiple spray gun nozzles 41. The device of the present invention has a simple structure, is easy to use and reusable, and has a low cost. In addition, online cleaning can reduce the impact on production time. At the same time, there is no need to disassemble and assemble the spray gun, saving time and manpower, and better meeting current production requirements.
