Description

Technical Field

[0001] The utility model relates to a device for stabilizing the water flow of a steel rolling vortex well, belonging to the technical field of steel rolling vortex well equipment. Background Art

[0002] The steel rolling process requires water descaling and cooling of the rolling mill. Each rolling mill has its own water circulation system, and a vortex well is an integral part of the water circulation system. The vortex well collects descaling water and turbid ring cooling water. Turbid ring water from the rolling mill is collected through a slag flushing ditch and then enters the vortex well through a water pipe in the middle of the vortex well, which is inclined toward the centerline of the vortex well. The water forms a vortex within the vortex well, which precipitates impurities such as iron oxide scale in the water. This vortex precipitation process provides a preliminary filtration of impurities such as iron oxide scale. The water from the vortex well is then lifted by a lift pump to the water treatment system. After treatment, it is cooled in a cooling tower and then recycled into a recovery tank for reuse. The sediment in the vortex well must be removed and centrally handled using an overhead crane grab. However, the water in the vortex well swirls rapidly, making slag removal difficult without shutting down the rolling mill. Contact between the slag ditch and the water flow can cause the wire rope to become tangled, which can severely impair operation or even damage equipment, leading to safety accidents.

[0003] Currently, dual-line shared swirl wells are increasingly being used in steel rolling projects. If both production lines were shut down for swirl well cleaning, production schedules would be significantly impacted. Therefore, under normal circumstances, slag removal is typically performed during rolling line maintenance. This approach, however, is time-limited and uncertain, making it impossible to effectively and thoroughly clean the swirl wells. This results in a high concentration of impurities in the subsequent water treatment process, which can easily accumulate in the cooling tower return water tank, causing a decrease in the return water tank's water capacity. Furthermore, cleaning the sludge in the return water tank is extremely difficult.

[0004] Therefore, it is crucial to complete the slag grabbing operation in the vortex well without stopping the machine. In order to break the limitation that the vortex well slag grabbing must be shut down and to successfully clean the sediment in the vortex well, it is necessary to solve the impact of the vortex well water flow on the slag grab bucket and make the slag grab ditch smoothly enter the bottom of the vortex well to clean the sediment.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of the present utility model.

[0015] The markings in the figure are as follows: swirl well 1, slag flushing groove 2, direction adjustment shaft 3, bracket 4, bevel gear 5, rotating rod 6, rotating rod fixing frame 7, guide plate 8, rotating adjustment shaft 9, rotating handle 10, shaft sleeve 11, bearing seat 12, bearing seat fixing plate 13. DETAILED DESCRIPTION

[0016] The utility model is composed of a direction-adjusting shaft 3, a bracket 4, a bevel gear 5, a rotating rod 6, a rotating rod fixing frame 7, and a guide plate 8.

[0017] As shown in the figure, the direction adjustment shaft 3 consists of a rotation adjustment shaft 9 and a rotation handle 10. The rotation adjustment shaft 9 is placed horizontally on one side above the wellhead of the vortex well 1. The front end of the rotation adjustment shaft 9 is located on the inner side of the wellhead of the vortex well 1. The rotation handle 10 is fixed to the rear end of the rotation adjustment shaft 9. The rotation handle 10 of the direction adjustment shaft 3 can rotate the rotation adjustment shaft 9.

[0018] The figure shows that the direction adjustment shaft 3 is supported by brackets 4. The two brackets 4 are fixed vertically to the ground below the rotation adjustment shaft 9. The upper ends of the brackets 4 are mounted with bushings 11 or bearing seats. The rotation adjustment shaft 9 of the direction adjustment shaft 3 is rotatably connected to the bushings 11 or bearing seats at the upper ends of the brackets 4.

[0019] The figure shows that the rotating rod 6 is a long vertical rod located above the water inlet of the slag flushing ditch 2 in the vortex well 1. The front end of the rotation adjustment shaft 9 of the direction adjustment shaft 3 is mounted with a bevel gear 5, and the upper end of the rotating rod 6 is mounted with a matching bevel gear 5. The two bevel gears 5 are meshed, and the rotation adjustment shaft 9 of the direction adjustment shaft 3 can drive the rotating rod 5 to rotate through the bevel gear 5.

[0020] The figure shows that the rotating rod fixing frame 7 supports the rotating rod 6, ensuring that the rotating rod 6 is fixed and rotated. Two rotating rod fixing frames 7 are distributed along the rotating rod 6 on the wall of the vortex well 1. The rear ends of the two rotating rod fixing frames 7 are fixedly connected to the wall of the vortex well 1. The front ends of the two rotating rod fixing frames 7 are respectively welded to the vertical bearing seat fixing plates 13. The two bearing seats 12 are respectively connected to the bearing seat fixing plates 13 at the front ends of the two rotating rod fixing frames 7 by bolts. Bearings are fixedly installed in the bearing seats 12, and the rod body of the rotating rod 6 passes through the bearings of the two bearing seats 12. The bearing seat 12 of the rotating rod 6 is connected to the front end of the rotating rod fixing frame 7 by bolts. In this way, when installing the rotating rod 6, the rotating rod 6 can be inserted into the bearing seat 12 first, and then the rotating rod 6 and the bearing seat 12 are connected as a whole to the bearing seat fixing plate 12 at the front end of the rotating fixing frame 7. This avoids the rotating rod 6 being inserted after the bearing seat 12 is welded to the rotating rod fixing frame 7, which results in the rotating rod 6 being able to only be inserted from below the bearing seat 12 due to the guide plate 8 at the lower end of the rotating rod 6, which is very inconvenient.

[0021] As shown in the figure, the guide plate 8 is fixedly installed at the lower end of the rotating rod 6, and the rotating rod 6 can drive the guide plate 8 to rotate. The rotating rod 6 and the guide plate 8 are connected by bolts, which facilitates the connection of the rotating rod 6 with the bearing seat 12 and the replacement of the guide plate 8. The plate surface of the guide plate 8 is opposite to the water flow inlet of the slag flushing ditch 2 of the vortex well 1. The guide plate 8 is circular, and the diameter of the guide plate 8 is larger than the water flow inlet of the slag flushing ditch 2. The distance between the lower end of the rotating rod 6 and the wall of the vortex well 1 is greater than the plate surface radius of the guide plate 8. In this way, the guide plate 8 can rotate freely without hitting the wall of the vortex well 1, and the plate surface of the guide plate 8 can be perpendicular, parallel or at any angle to the water flow direction of the slag flushing ditch 2. These angles can be controlled by the rotation direction adjustment shaft 3.

[0022] The use process of this utility model is as follows:

[0023] During normal production, the surface of the guide plate 8 is parallel to the water inlet direction of the slag flushing ditch 2 of the vortex well 1, which does not affect the formation of the rotating water flow in the vortex well 1; when slag needs to be caught, the staff rotates the rotating adjustment shaft 9 by rotating the rotating handle 10 of the rotating direction adjustment shaft 3 next to the vortex well 1, and the rotating adjustment shaft 9 drives the rotating rod 6 to rotate through the front bevel gear 5, and the rotating rod 6 drives the guide plate 8 to rotate, so that the plate surface of the guide plate 8 rotates to be perpendicular to the water flow direction of the slag flushing ditch 2, and the water flow out of the slag flushing ditch 2 is divided into two streams, entering the vortex well 1 from both sides of the guide plate 8, and the water flows on both sides converge along the edge of the vortex well 1, offsetting each other's impact, so as to achieve the effect of temporary stability of the water flow in the vortex well 1.

[0024] After the water flow in vortex well 1 stabilizes, the operator directs the overhead crane above vortex well 1 to carry out slag grabbing operations. Each slag grabbing operation does not exceed half an hour, once a day, and the amount of slag grabbed fully meets the usage requirements.

[0025] An embodiment of the present invention is as follows:

[0026] The diameter of the rotation adjustment shaft 9 of the direction adjustment shaft 3 is 60 mm and the length is 1200 mm;

[0027] The diameter of the bracket 4 is 30 mm and the height is 50 mm;

[0028] The diameter of the bevel gear 5 is 400 mm;

[0029] The diameter of the rotating rod 6 is 80 mm and the length is 82000 mm;

[0030] The diameter of the rotating rod fixing frame 7 is 30mm and the length is 550mm

[0031] The guide plate 8 has a diameter of 1000 mm and a thickness of 20 mm.
