Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery and equipment technology, specifically a flow guiding device applied to a continuous casting machine. Background Technology

[0002] Currently, the cooling water in continuous casting machines in steel plants typically uses a two-inlet, two-outlet system for the conveyor rollers. The cooling water used for roller cooling is generally open-circuit, meaning it flows in through the inlet holes, passes through the roller core, and then flows out through the outlet holes on the other side to cool the rollers. However, the cooling water flowing out of the outlet holes lacks any guiding measures, causing it to splash onto the roller beam supports, drive mechanism brackets, and main frame. If left untreated for a long time, this can lead to corrosion, steel plate delamination, and increased safety risks. Furthermore, due to the high operating rate and limited downtime for water supply in continuous casting machines, there is insufficient time for maintenance and replacement. Utility Model Content

[0003] The purpose of this invention is to provide a flow guiding device for use on a continuous casting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flow guiding device applied to a continuous casting machine, the continuous casting machine including a roller body, both ends of which are equipped with drive shafts, the roller body being rotatably connected to bearing seats via the drive shafts, roller beam supports being installed at the bottom of both bearing seats, a connecting block being provided between the roller beam supports, one end of the roller body forming a water inlet hole, and the other end forming a water outlet hole communicating with the water inlet hole, the water inlet hole and the water outlet hole being located between the roller body and the drive shaft, and a receiving space being formed between one end of the water outlet hole of the roller body and the roller beam support, wherein the flow guiding device includes a flow guiding body and a flow guiding pipe, and The guide body consists of a base plate, a front guide plate fixed to the base plate, and several side plates. The base plate, the front guide plate, and the side plates together form a guide channel with an upper opening. The guide channel is used to store cooling water flowing out from the water outlet. The front guide plate is attached to the roller beam support and extends into the accommodating space along a first direction. At the same time, the end of the front guide plate away from the base plate is higher than the water outlet. The base plate is fixed to the top surface of the connecting block, and a guide hole is provided on the base plate. The guide pipe is installed on the base plate and communicates with the guide hole. The guide pipe is used to unclog the cooling water stored in the guide channel.

[0005] Based on the above technical features, the guide device in this invention is installed directly below the water outlet of the roller body. The base plate is installed above the surface of the connecting block between the roller beam supports. The front guide plate is in surface contact with the roller beam support. When the roller body is stationary and not rotating, the cooling water inside the roller body flows directly from the water outlet of the roller body into the guide groove of the guide device, and then flows out through the guide pipe to the pit to the vortex well. When the roller body is rotating, the cooling water inside the roller body has an impact force when it flows out, and is thrown from the water outlet of the roller body onto the front guide plate of the guide device, then flows into the guide groove, and finally flows out through the guide pipe to the roller pit to the vortex well. This invention can guide the cooling water into the roller pit to the vortex well in both the non-rotating and rotating states of the roller body, achieving the purpose of external drainage and guidance of the roller body cooling water. This avoids the cooling water hitting the roller beam support, transmission machine bracket, and main frame, which can cause corrosion and steel plate delamination problems in the continuous casting machine if not treated for a long time, thereby improving the service life of the equipment.

[0006] In this preferred embodiment, the flow guide body consists of a rectangular base plate, a front guide plate, and three side plates. The front guide plate and its opposite side plate are fixedly connected to the left and right sides of the base plate, respectively. The other two side plates are fixedly connected to the base plate, the front guide plate, and the rear guide plate, respectively, and together form the rectangular flow guide groove.

[0007] Based on the above technical features, the design of the above-mentioned flow guide body structure is reasonable, which helps workers to install it in practice. At the same time, it can be applied to various specific working conditions and has wide applicability.

[0008] In this preferred embodiment, the end of the front guide plate furthest from the base plate is higher than the water outlet, and the height of the front guide plate perpendicular to the base plate is less than the vertical distance between the bottom of the drive shaft and the top of the connecting block. More preferably, the height of the front guide plate perpendicular to the base plate is 20mm to 30mm smaller than the vertical distance between the drive shaft and the connecting block.

[0009] Based on the above technical features, the end of the front guide plate away from the bottom plate is higher than the water outlet position, and the height dimension of the front guide plate in the direction perpendicular to the bottom plate is smaller than the vertical distance between the bottom of the drive shaft and the top of the connecting block. While ensuring that the flow guiding device can guide the flow quickly, it also avoids the front guide plate from touching the drive shaft, thus affecting the transmission performance of the continuous casting machine.

[0010] In this preferred embodiment, the front guide plate has an arc-shaped opening at one end away from the base plate, through which the drive shaft passes, and the arc-shaped opening is adapted to the outer surface of the drive shaft.

[0011] Based on the above technical features, the upper part of the front guide plate has an arc-shaped structure and is well matched with the dimensions of the roller's drive shaft. This serves to block and guide water flow, preventing external drainage from flowing out, and also avoids the front guide plate from contacting the drive shaft, thus affecting the transmission function of the continuous casting machine.

[0012] In this preferred embodiment, the two side plates are arranged on the front and rear sides of the base plate, and the distance between the two side plates is greater than the width of the connecting block. Along the width direction of the connecting block, the guide pipe is located on the front and rear sides of the guide body.

[0013] Based on the above technical features, the installation position of the connecting block between the guide pipe and the roller beam support is ensured.

[0014] In the preferred embodiment of this technical solution, the bottom plate, the front guide plate, and the three side plates are welded together from stainless steel plates to form the flow guide body.

[0015] Based on the above technical features, the flow guiding device is made of stainless steel by welding, which effectively improves the corrosion resistance of the flow guiding device and makes it less susceptible to corrosion, peeling and deformation caused by the external environment.

[0016] In this preferred embodiment, the base plate is welded to the top of the connecting block, and the guide plate is in contact with and welded to the roller beam support surface.

[0017] Based on the above technical features, the base plate is welded and fixed above the surface of the connecting block between the roller beam supports, and the front guide plate is in surface contact with the roller body support of the roller beam and welded and fixed. Its flow guiding device has a simple structural design and low manufacturing cost. After application, it can greatly improve the service life of the equipment and reduce safety hazards.

Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0030] Before understanding this utility model, it is important to understand that the cooling water inlet and outlet of the conveyor rollers of a continuous casting machine in a steel plant generally adopts a two-inlet, two-outlet configuration, such as... Figure 1As shown, the cooling water used for cooling the roller is generally open-circuit water. The cooling water flows in from the inlet hole, passes through the core of the roller, and then flows out from the outlet hole on the other side to cool the roller. The continuous casting machine 1 includes a roller 101. Both ends of the roller 101 are equipped with drive shafts 102. The roller 101 is rotatably connected to the bearing housing 103 through the drive shafts 102. Roller beam supports 104 are installed at the bottom of the two bearing housings 103. A connecting block 105 is provided between the roller beam supports 104. One end of the roller 101 forms an inlet hole, and the other end forms an outlet hole that communicates with the inlet hole. The inlet hole and the outlet hole are both located between the roller 101 and the drive shaft 102. A receiving space 3 is formed between the outlet hole of the roller 101 and the roller beam support 104. This receiving space 3 is used to cooperate with the installation of the flow guiding device 2.

[0031] like Figures 2 to 7 As shown, this utility model provides a technical solution: a flow guiding device applied to a continuous casting machine. The flow guiding device 2 includes a flow guiding body 21 and a flow guiding pipe 22. The flow guiding body 21 consists of a base plate 203, a front guide plate 201 fixed to the base plate 203, and several side plates 202. The base plate 203, the front guide plate 201, and the several side plates 202 enclose a flow guiding groove 5 with an upper opening. The flow guiding groove 5 is used to store cooling water flowing out from the water outlet. The front guide plate 201 is attached to the roller beam support 104 and extends into the accommodating space 3 along the first direction. At the same time, the end of the front guide plate 201 away from the base plate 203 is higher than the water outlet position. The base plate 203 is fixed to the top surface of the connecting block 105, and a flow guiding hole is provided on the base plate 203. The guide pipe 22 is installed on the base plate 203 and is connected to the guide hole. The guide pipe 22 is used to unclog the cooling water stored in the guide channel 5.

[0032] In this invention, the flow guiding device 2 is installed directly below the water outlet of the roller body 101. The base plate 203 is installed above the surface of the connecting block 105 between the roller beam supports 104. The front guide plate 201 is in surface contact with the roller beam support 104. When the roller body 101 is stationary and not rotating, the cooling water in the roller body 101 flows directly from the water outlet of the roller body 101 into the flow guiding groove 5 of the flow guiding device 2, and then flows out through the flow guiding pipe 22 to the pit to the vortex well. When the roller body 101 is rotating, the cooling water in the roller body 101 has an impact force when it flows out, and is thrown from the water outlet of the roller body 101 onto the front guide plate 201 of the flow guiding device 2, then flows into the flow guiding groove 5, and finally flows out through the flow guiding pipe 22 to the roller pit to the vortex well. This invention guides cooling water into the roller conveyor pit and vortex well in both the non-rotating and rotating states of the roller body 101, achieving the purpose of external drainage and guiding of cooling water from the roller body 101. This avoids the problem of cooling water hitting the roller beam support 104, transmission machine bracket and main frame, which would cause corrosion and steel plate delamination and detachment of the continuous casting machine 1 if not treated for a long time, thereby improving the service life of the equipment.

[0033] Furthermore, the flow guide body 21 is composed of a rectangular base plate 203, a front guide plate 201, and three side plates 202. The front guide plate 201 and its opposite side plate 202 are fixedly connected to the left and right sides of the base plate 203, respectively. The other two side plates 202 are fixedly connected to the base plate 203, the front guide plate 201, and the rear guide plate, respectively, and together form a rectangular flow guide groove 5.

[0034] Furthermore, two opposing side plates 202 are arranged on the front and rear sides of the base plate 203, and the distance between the two side plates 202 is greater than the width of the connecting block 105. Along the width direction of the connecting block 105, the guide pipe 22 is located on the front and rear sides of the guide body 21. The distance between the two opposing side plates 202 must be greater than the width of the connecting block 105 to ensure that the guide pipe 22 is arranged on the outside of the connecting block 105 between the roller beam supports 104. In this utility model, the distance between the two opposing side plates 202 is in the range of 280mm-320mm, preferably 300mm, and the distance between the guide pipe 22 and the center of the guide groove 5 is 135mm, ensuring that the guide pipe 22 is approximately in contact with the side of the connecting block 105.

[0035] The distance between the front guide plate 201 and the opposite side plate 202 depends on the diameter of the water outlet of the roller body 101 and the flow rate of the cooling water in the roller body 101. In this utility model, the distance between the front guide plate 201 and the opposite side plate 202 is in the range of 180mm-220mm. Preferably, the distance between the front and rear side plates 202 is 200mm. In addition, the diameter of the guide pipe 22 depends on the flow difference between the external drainage of the roller body 101 and the external drainage of the guide pipe 22, ensuring that the water level inside the guide device 2 is not higher than the height of the three side plates 202, and the length of the guide pipe 22 is greater than the height distance of the connecting block 105. In this utility model, the diameter of the guide pipe 22 is 20mm-24mm, the length of the guide pipe 22 is not less than 300mm, and the height of the three side plates 202 is not less than 90mm. Preferably, the diameter of the guide pipe 22 is 22mm, the length of the guide pipe 22 is 305mm, which is compatible with the guide body 21, and the height of the three side plates 202 is not less than 95mm, saving materials while meeting normal use requirements.

[0036] The base plate 203, the front guide plate 201 and the three side plates 202 are welded together from stainless steel plates to form the flow guide body 21. The flow guide device 2 is made of 5mm thick stainless steel plate, which effectively improves the corrosion resistance of the flow guide device 2 and makes it less susceptible to corrosion, peeling and deformation due to the influence of the external environment.

[0037] The base plate 203 is welded to the top of the connecting block 105. Simultaneously, the front guide plate 201 is in surface contact with and welded to the roller beam support 104. The base plate 203 is welded and fixed above the surface of the connecting block 105 between the roller beam supports 104. The front guide plate 201 is in surface contact with and welded to the roller body 101 support of the roller beam. Its guiding device 2 has a simple structural design, low manufacturing cost, and its application can greatly improve the service life of the equipment and reduce safety hazards.

[0038] Specifically, such as Figures 3 to 6As shown, in the first embodiment of the flow guiding device 2, the end of the front guide plate 201 away from the bottom plate 203 is higher than the water outlet position, and the height dimension of the front guide plate 201 in the direction perpendicular to the bottom plate 203 is less than the vertical distance between the bottom of the drive shaft and the top of the connecting block 105. Specifically, in the specific embodiment of this utility model, the height dimension of the front guide plate 201 in the direction perpendicular to the bottom plate 203 is 20mm to 30mm smaller than the vertical distance between the drive shaft and the connecting block 105. Specifically, the vertical distance can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm. The end of the front guide plate 201 away from the bottom plate 203 is higher than the water outlet position, and the height dimension of the front guide plate 201 in the direction perpendicular to the bottom plate 203 is less than the vertical distance between the bottom of the drive shaft 102 and the top of the connecting block 105. While ensuring that the flow guiding device 2 can guide the flow quickly, it also avoids the front guide plate 201 from touching the drive shaft 102, thus affecting the transmission performance of the continuous casting machine 1.

[0039] Specifically, such as Figure 7 As shown, in the second embodiment of the flow guiding device 2, an arc-shaped opening 4 is formed at the end of the front guide plate 201 away from the bottom plate 203. The drive shaft passes through the arc-shaped opening 4, and the arc-shaped opening 4 is adapted to the outer surface of the drive shaft. The upper part of the front guide plate 201 has an arc-shaped structure and is well matched with the dimensions of the drive shaft 102 of the roller body 101. This serves to block and guide water flow, preventing external drainage from flowing out, and also correspondingly preventing the front guide plate 201 from contacting the drive shaft 102, thus affecting the transmission function of the continuous casting machine.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
