Description

Technical Field

[0001] The utility model relates to the technical field of vortex wells, and more specifically, to a vortex well steel slag cleaning system. Background Art

[0002] A vortex well is a vortex sedimentation tank. Sewage flows into the grit chamber along the tangential direction from the inlet. The motor drives the turntable and impeller to rotate. Under the action of centrifugal force, sand grains with a larger density in the sewage are thrown towards the pool wall and fall into the sand hopper, while the organic matter remains in the water. By adjusting the rotation speed, the best sedimentation effect can be achieved, and it is widely used in the steel production process. In the existing vortex well, as Figure 1 shown, during the operation of the vortex well, sewage enters the sedimentation area a at the bottom of the well for sedimentation. Part of the scale (steel slag) will precipitate at the bottom of the intermediate sedimentation bucket b and needs to be manually cleaned every 6 months, with each cleaning taking 2 days, resulting in a very high labor intensity and cost.

[0006] As a further improvement, a solenoid valve is arranged on the slag flushing pipe outside the vortex well.

[0007] Furthermore, a plurality of the spray water pipes are evenly distributed at the bottom of the annular water pipe, and the diameter of the spray water pipe is smaller than that of the annular water pipe. The inclination angle between each spray water pipe and the bottom surface of the intermediate sedimentation bucket is 30° - 60°.

Detailed implementation mode

[0022] The following further describes the present utility model with reference to specific embodiments in the accompanying drawings.

[0023] Refer to Figure 2-5 , a swirl well steel slag cleaning system of the present utility model includes an annular water pipe 1, a slag flushing pipeline assembly and a slag extraction pipeline assembly. Among them, the slag flushing pipeline assembly is used to provide high-pressure water to the annular water pipe 1, and the slag extraction pipeline assembly is used to extract steel slag. Therefore, the diameter of the pipeline corresponding to the slag extraction pipeline assembly should be made larger. The annular water pipe 1 is installed at the lower part of the intermediate sedimentation tank b. A plurality of water spray pipes 2 communicated with it are arranged at the bottom of the annular water pipe 1, which can spray high-pressure water flows to the bottom of the intermediate sedimentation tank b. Each water spray pipe 2 extends obliquely downward along the circumferential direction of the annular water pipe 1. The obliquely arranged water spray pipes 2 can spray obliquely flowing water, so that a swirl can be formed at the bottom of the intermediate sedimentation tank b, which is more helpful for the lifting of steel slag; the slag flushing pipeline assembly includes a slag flushing pipe 3. One end of the slag flushing pipe 3 is communicated with the annular water pipe 1, and the other end penetrates through the swirl well 4 and is connected with a slag flushing pump 5 to provide high-pressure water flow to the annular water pipe 1; the slag extraction pipeline assembly includes a slag extraction pipe 6. One end of the slag extraction pipe 6 is inserted into the intermediate sedimentation tank b, and the other end penetrates through the swirl well 4 and is connected with a slag extraction pump, which can extract water and lifted steel slag.

[0024] For the swirl well steel slag cleaning system of the present utility model, by installing an annular water pipe 1 in the intermediate sedimentation tank b and arranging a plurality of obliquely arranged water spray pipes 2 at the bottom of the annular water pipe 1, during the operation of the swirl well, obliquely flowing water can be sprayed to the bottom of the intermediate sedimentation tank b through the water spray pipes 2, so as to form a swirl at the bottom of the intermediate sedimentation tank b, making the steel slag at the bottom of the intermediate sedimentation tank b lifted. At this time, the slag extraction pipe 6 can suck away the steel slag, which is convenient for extracting the steel slag in the intermediate sedimentation tank b, realizing the discharge of the steel slag in the intermediate sedimentation tank, without the need for manual regular cleaning, and the swirl well can always operate normally, effectively reducing the labor intensity and production cost.

[0025] Preferably, a solenoid valve is arranged on the slag flushing pipe 3 outside the swirl well 4. The slag flushing pipe 3 is provided with an independently controlled solenoid valve, so that an existing slag flushing pump can be used, such as the slag flushing pump for flushing the sedimentation area a of the swirl well. When it is necessary to clean the intermediate sedimentation tank b, just open the solenoid valve, which does not affect the use of the existing slag flushing pump and further reduces the manufacturing cost.

[0026] Preferably, multiple water spray pipes 2 are evenly distributed at the bottom of the annular water pipe 1, which can more easily form a swirl. Moreover, the diameter of the water spray pipe 2 is smaller than that of the annular water pipe 1. With a small-diameter water spray pipe 2, the water flow velocity ejected is faster, and it is easier to form a swirl. The inclination angle between each water spray pipe 2 and the bottom surface of the middle sedimentation tank b is 30° to 60°. By reasonably optimizing the inclination angle of the water spray pipe 2, it is easier to form a swirl, thereby improving the effect of slag lifting.

[0027] Preferably, one end of the slag extraction pipe 6 extends to the position where the annular water pipe 1 is located. The slag extraction pipe 6 is closer to the annular water pipe 1, which can timely extract the lifted steel slag and is more conducive to the discharge of steel slag.

[0028] Preferably, the annular water pipe 1 is detachably installed in the middle sedimentation tank b, which is convenient for disassembly, installation and maintenance. The slag flushing pipe 3 and the annular water pipe 1 are connected by a flange, so that the slag flushing pipe 3 is also installed in a detachable manner, avoiding the problem of interference between the annular water pipe 1 and the slag flushing pipe 3 when the annular water pipe 1 is disassembled.

[0029] Preferably, a plurality of support plates 8 are provided on the inner wall of the middle sedimentation tank b. The plurality of support plates 8 are fixedly connected to the middle sedimentation tank b and are horizontally arranged. A plurality of connecting plates 9 are provided on the inner wall of the annular water pipe 1. The number of the connecting plates 9 is the same as that of the support plates 8. The connecting plates 9 are respectively lapped on the support plates 8, playing a role in supporting the connecting plates 9 and the annular water pipe 1. Moreover, the connecting plates 9 and the support plates 8 are connected by fastening bolts 10 to realize the fixed installation of the connecting plates 9 and the annular water pipe 1, and at the same time meet the requirements of disassembly, installation and maintenance. Further, the plurality of connecting plates 9 are evenly distributed on the inner wall of the annular water pipe 1. Each connecting plate 9 is provided with a through hole 7 with a diameter larger than the diameter of the screw of the fastening bolt 10, which is convenient for the fastening bolt 10 to pass through to realize quick fixed connection. Each support plate 8 is provided with a threaded hole. The fastening bolt 10 passes through the through hole 7 and is threadedly connected to the threaded hole to realize the connection and fixation between the connecting plate 9 and the support plate 8. Furthermore, the annular water pipe 1 is composed of two semi-circular pipes in a half-and-half manner, and the two semi-circular pipes are connected by a flange. With a half-and-half structure, it is convenient to take out the entire annular water pipe 1 from the middle sedimentation tank b during disassembly and assembly, and disassembly, installation and maintenance are more convenient.

[0030] The above is only the preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
