Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical mechanical equipment, and specifically to a diversion device applied to a continuous casting machine. Background Art

[0002] At present, the inlet and return water mode of the cooling water of the driving roller body of the conveying roller table of the continuous casting machine in the steel mill generally adopts a two-in and two-out mode, and the cooling water used for roller body cooling is generally open-circuit water. Among them, the cooling water flows in from the water inlet hole, passes through the core of the roller body, and then flows out from the water outlet hole on the other side to achieve the cooling of the roller body. Since there is no diversion measure for the cooling water flowing out from the water outlet hole of the roller body, the cooling water hits the roller table beam support, the drive machine support and the main frame. If not processed for a long time, it will cause corrosion of the continuous casting machine and peeling off of the steel plate, thereby increasing the risk of potential safety hazards. Due to the high operation rate of the continuous casting machine and the short shutdown and water cut time, there is not enough time to repair and replace the continuous casting machine. Summary of the Invention

[0003] The purpose of the present invention is to provide a diversion device applied to a continuous casting machine to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A diversion device applied to a continuous casting machine, the continuous casting machine includes a roller body, drive shafts are installed at both ends of the roller body, the roller body is rotationally connected to a bearing seat through the drive shafts, roller table beam supports are installed at the bottoms of the two bearing seats, a connecting block is arranged between the roller table beam supports, a water inlet hole is formed at one end of the roller body, and a water outlet hole communicated with the water inlet hole is formed at the other end, both the water inlet hole and the water outlet hole are located between the roller body and the drive shaft, a receiving space is formed between the water outlet hole end of the roller body and the roller table beam support. Among them, the diversion device includes a diversion body and a diversion pipe. The diversion body is composed of a bottom plate, a front guide plate fixed on the bottom plate, and several side plates. Moreover, the bottom plate, the front guide plate and the several side plates enclose to form a diversion groove with an upper opening. The diversion groove is used for storing the cooling water flowing out from the water outlet hole. The front guide plate is attached to the roller table beam support and extends into the receiving space along a first direction. At the same time, the end of the front guide plate away from the bottom plate is higher than the position of the water outlet hole. The bottom plate is fixed on the top surface of the connecting block, and a diversion hole is opened on the bottom plate; the diversion pipe is installed on the bottom plate and communicated with the diversion hole, and the diversion pipe is used for dredging the cooling water stored in the diversion groove.

The bottom plate is installed above the surface of the connecting block between the roller table beam supports. The front guide plate is in surface contact with the roller table beam support. When the cooling water in the roller body is in a stationary and non-rotating state, it directly flows out from the water outlet holes of the roller body into the diversion groove of the diversion device, and then flows out through the diversion pipe to the pit and then to the vortex well. When the cooling water in the roller body is in a rotating state, there is an impact force when the cooling water flows out, and it is thrown from the water outlet holes of the roller body onto the front guide plate of the diversion device, then flows into the diversion groove, and finally flows out through the diversion pipe to the roller table pit and then to the vortex well. The present invention can guide the cooling water into the roller table pit and then to the vortex well both in the non-rotating state and the rotating state of the roller body, achieving the purpose of diverting the cooling water of the roller table roller body to the outside, avoiding the cooling water hitting the roller table beam support, the drive machine support and the main frame, and if not processed for a long time, it will cause problems such as corrosion of the continuous casting machine and peeling off of the steel plate, thereby improving the service life of the equipment.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0028] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the accompanying drawings are not drawn in actual proportional relationships.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined or described in one drawing, it will not be necessary to further discuss and describe it specifically in the description of subsequent drawings.

[0030] Before understanding the present invention, it should be clear that the inlet and return water modes of the cooling water of the transmission roller body of the conveying roller path of the continuous casting machine 1 in the steel mill generally adopt the two-in and two-out mode, such as Figure 1As shown, the cooling water for the roll body is generally open-circuit water. Among them, the cooling water flows in from the water inlet hole, passes through the core of the roll body, and then flows out from the water outlet hole on the other side to achieve the cooling of the roll body. The continuous casting machine 1 includes a roll body 101. Transmission shafts 102 are installed at both ends of the roll body 101. The roll body 101 is rotationally connected to the bearing block 103 through the transmission shafts 102. Roll track beam supports 104 are installed at the bottoms of the two bearing blocks 103. A connecting block 105 is arranged between the roll track beam supports 104. A water inlet hole is formed at one end of the roll body 101, and a water outlet hole communicating with the water inlet hole is formed at the other end. Both the water inlet hole and the water outlet hole are located between the roll body 101 and the transmission shaft 102. A receiving space 3 is formed between the water outlet hole end of the roll body 101 and the roll track beam support 104. The receiving space 3 is used to cooperate with the installation of the diversion device 2.

[0031] As Figures 2 to 7 As shown, the present invention provides a technical solution: a diversion device applied to a continuous casting machine. The diversion device 2 includes a diversion body 21 and a diversion pipe 22. The diversion body 21 is composed of a bottom plate 203, a front guide plate 201 fixedly connected to the bottom plate 203, and several side plates 202. Moreover, the bottom plate 203, the front guide plate 201, and the several side plates 202 enclose a diversion groove 5 with an upper opening. The diversion groove 5 is used to store the cooling water flowing out from the water outlet hole. The front guide plate 201 is in contact with the roll track beam support 104 and extends into the receiving space 3 along the first direction. At the same time, the end of the front guide plate 201 away from the bottom plate 203 is higher than the position of the water outlet hole. The bottom plate 203 is fixedly connected to the top surface of the connecting block 105. A diversion hole is opened on the bottom plate 203. The diversion pipe 22 is installed on the bottom plate 203 and communicates with the diversion hole. The diversion pipe 22 is used to dredge the cooling water stored in the diversion groove 5.

[0032] In the present invention, the diversion device 2 is installed directly below the water outlet holes of the roller body 101. The bottom plate 203 is installed above the surface of the connecting block 105 between the roller table beam supports 104. The front guide plate 201 is in surface contact with the roller table beam support 104. When the cooling water in the roller body 101 is in a stationary and non-rotating state, it directly flows out from the water outlet holes of the roller body 101 into the diversion groove 5 of the diversion device 2, and then flows out through the diversion pipe 22 to the pit and then to the swirl well. When the roller body 101 is in a rotating state, the cooling water has an impact force when flowing out, is thrown from the water outlet holes of the roller body 101 onto the front guide plate 201 of the diversion device 2, then flows into the diversion groove 5, and finally flows out through the diversion pipe 22 to the roller table pit and then to the swirl well. The present invention can guide the cooling water into the roller table pit and then to the swirl well both when the roller body 101 is in a non-rotating state and a rotating state, achieving the purpose of diverting the cooling water of the roller table roller body 101 to the outside, avoiding the cooling water hitting the roller table beam supports 104, the drive machine support and the main frame, and preventing problems such as corrosion of the continuous casting machine 1 and peeling off of the steel plate layers from occurring if not processed for a long time, thereby improving the service life of the equipment.

[0033] Further, the diversion body 21 is composed of a rectangular bottom plate 203, a front guide plate 201 and three side plates 202. Among them, the front guide plate 201 and a side plate 202 opposite to it are respectively fixedly connected to the left and right sides of the bottom plate 203, and the other two side plates 202 are respectively fixedly connected to the bottom plate 203, the front guide plate 201 and the rear guide plate and enclose each other to form a rectangular diversion groove 5.

[0034] Still further, two opposite side plates 202 are arranged on the front and rear sides of the bottom 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 diversion pipe 22 is located on one side of the front and rear of the diversion body 21. The distance between the two opposite front and rear side plates 202 must be greater than the width of the connecting block 105, ensuring that the diversion pipe 22 is arranged outside the connecting block 105 between the roller table beam supports 104. In the present invention, the distance between the two front and rear side plates 202 ranges from 280 mm to 320 mm. Preferably, the distance between the two front and rear side plates 202 is 300 mm, and the distance between the diversion pipe 22 and the center of the diversion groove 5 is 135 mm, ensuring that the diversion pipe 22 is roughly attached to the side surface of the connecting block 105.

[0035] The distance between the front guide plate 201 and the opposite side plates 202 depends on the diameter of the water outlet holes of the roller body 101 and the flow rate of the cooling water inside the roller body 101; in the present invention, the distance between the front guide plate 201 and the opposite side plates 202 ranges from 180 mm to 220 mm. Preferably, the distance between the front and rear side plates 202 is 200 mm. In addition, the diameter of the diversion pipe 22 depends on the flow rate difference between the externally drained cooling water of the roller body 101 and the water drained outside the diversion pipe 22, ensuring that the water level inside the diversion device 2 cannot be higher than the height of the three side plates 202, and the length of the diversion pipe 22 is greater than the height distance of the connecting block 105; in the present invention, the diameter of the diversion pipe 22 is 20 mm to 24 mm, the length of the diversion pipe 22 is not less than 300 mm, and the height of the three side plates 202 is not less than 90 mm. Preferably, the diameter of the diversion pipe 22 is 22 mm, the length of the diversion pipe 22 is 305 mm, which is adapted to the diversion body 21, and the height of the three side plates 202 is not less than 95 mm, saving materials while meeting normal use requirements.

[0036] The bottom plate 203, the front guide plate 201 and the three side plates 202 are formed by welding stainless steel plates to form the diversion body 21, and the diversion device 2 thereof is made by welding 5-mm-thick stainless steel plates, effectively improving the corrosion resistance of the diversion device 2 and not being easily corroded, peeled or deformed by the external environment.

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

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

[0039] Specifically as Figure 7 As shown, it is the second embodiment of the flow guiding device 2. One end of the front guide plate 201 away from the bottom plate 203 forms an arc-shaped opening 4. The transmission shaft passes through the arc-shaped opening 4, and the formed arc-shaped opening 4 is adapted to the outer surface of the transmission shaft. The upper part of the front guide plate 201 is an arc-shaped structure and is well matched with the size of the transmission shaft 102 of the roller body 101, playing a role in blocking water and guiding the flow. On the premise of avoiding the outflow of external drainage, it also correspondingly avoids the front guide plate 201 from touching the transmission shaft 102, which affects the transmission function of the continuous casting machine.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
