Description

Technical Field

[0001] This utility model relates to the technical field of converter steelmaking equipment, and in particular to a converter water seal cylinder slag flushing device. Background Technology

[0002] The water seal cylinder is one of the main process equipment in the converter smelting process. Its function is to cool the flue gas and ensure that the gas generated during the converter blowing process enters the gas holder safely and stably, effectively preventing safety accidents that may be caused by gas backflow. In actual production applications, the bottom and inner perimeter of the water seal cylinder accumulate a lot of impurities such as silt and steel slag, which are difficult to remove and time-consuming and labor-intensive to clean. This leads to a sharp decrease in water volume, a decline in the water seal effect, and gas leakage, which seriously affects the production process and equipment safety, resulting in economic losses. Therefore, a slag flushing device for converter water seal cylinders is provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a converter water seal cylinder slag flushing device. By setting a first branch pipe as a branch water pipe in the main turbid circulating water pipeline, and through the coordinated use of a second branch pipe, annular pipe, and nozzles, a slag flushing vortex is formed inside the water seal cylinder body, exerting a stirring effect, improving siphon capacity, further enhancing slag flushing capacity, reducing sludge deposition, thereby reducing the sludge cleaning cycle for on-site personnel, allowing sludge inside the water seal cylinder body to fall quickly for easy cleaning, and helping to improve processability, reduce the risk of gas backflow, and reduce the frequency of equipment accidents such as pipeline corrosion and water leakage, thus overcoming the shortcomings of existing technologies.

[0005] A converter water seal cylinder slag flushing device includes a turbid circulating water main pipe and a water seal cylinder body. A first branch pipe is connected to one side of the turbid circulating water main pipe. A valve is connected to the lower end of the first branch pipe. A second branch pipe is connected to the lower end of the valve. The lower end of the second branch pipe extends to the top of the water seal cylinder body and a nozzle is installed at an angle through a flow divider assembly. An anti-splash structure is connected to the upper end of the water seal cylinder body and outside the flow divider assembly.

[0006] As a further embodiment of this utility model: the diversion assembly includes an annular pipe connected to the lower end of the second branch pipe, and the nozzle is installed at the bottom of the annular pipe.

[0007] As a further improvement of this utility model, at least four nozzles are provided and are evenly distributed on the annular tube.

[0010] As a further improvement of this utility model: the inner wall of the retaining ring is fixed with support rods at equal intervals, and one end of the support rod is provided with a pipe clamp, which is clamped around the outside of the annular tube.

[0011] As a further improvement of this utility model, the diameters of the second branch pipe and the annular pipe are both smaller than the diameter of the first branch pipe.

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

[0013] By setting up a first branch pipe as a branch water pipe in the main turbidity circulating water pipeline, and through the combined use of the second branch pipe, the ring pipe and the nozzle, a slag-flushing vortex is formed inside the water seal cylinder, which exerts a stirring effect, improves the siphon capacity, further enhances the slag-flushing capacity, reduces the current situation of sludge deposition, thereby reducing the cycle of sludge cleaning by on-site personnel, allowing the sludge inside the water seal cylinder to fall quickly and be easy to clean, and also helps to improve processability, reduce the risk of gas backflow, and reduce the frequency of equipment accidents such as pipeline corrosion and water leakage.

[0019] 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.

[0020] Example 1, referring to Figure 1-4A converter water seal cylinder slag flushing device includes a turbid circulating water main pipe 1 and a water seal cylinder body 6. A first branch pipe 2 is connected to one side of the turbid circulating water main pipe 1. A valve 3 is connected to the lower end of the first branch pipe 2. A second branch pipe 4 is connected to the lower end of the valve 3. The lower end of the second branch pipe 4 extends to the top of the water seal cylinder body 6 and a nozzle 9 is installed at an angle through a diversion component. A splash-proof structure is connected to the upper end of the water seal cylinder body 6 and located outside the diversion component.

[0021] The diversion assembly includes an annular pipe 7 connected to the lower end of the second branch pipe 4, and nozzles 9 are installed at the bottom of the annular pipe 7. At least four nozzles 9 are provided and are evenly distributed on the annular pipe 7.

[0022] The diameters of the second branch pipe 4 and the annular pipe 7 are both smaller than the diameter of the first branch pipe 2, which can increase the pressure and flow rate of the water in the second branch pipe 4 and the annular pipe 7.

[0023] During on-site installation, without affecting the overall flow rate, a suitable hole is made on the elbow surface of the main turbid water pipe 1, and the first branch pipe 2 is welded to the hole. The inclined nozzle 9 makes the water flow form a slag-flushing vortex on the inner wall of the water seal cylinder body 6 at a 45-degree angle, exerting a stirring effect, improving the siphon capacity, further strengthening the slag flushing capacity, reducing the current situation of sludge deposition, reducing the sludge cleaning cycle for on-site personnel, and making the sludge inside the water seal cylinder body 6 fall down quickly for easy cleaning.

[0024] Example 2 is an optimization based on Example 1. Specifically, the anti-splash structure includes a retaining ring 5 connected to the upper end of the water seal cylinder body 6 via a flange. The upper end of the retaining ring 5 is provided with an arc-shaped water-blocking part 8, and a bayonet 10 is provided on the arc-shaped water-blocking part 8. The second branch pipe 4 is snapped into the bayonet 10.

[0025] Support rods 11 are fixed at equal intervals on the inner wall of the retaining ring 5. One end of the support rod 11 is provided with a pipe clamp 12, which clamps the outside of the annular pipe 7 and provides stable support for the annular pipe 7.

[0026] The baffle ring 5 and the arc-shaped water-blocking part 8 can block the upward splashing water droplets and return them to the water seal cylinder body 6, thus preventing the flushing water from polluting the surrounding environment.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
