Description

Technical Field

[0001] The utility model relates to the field of slab cleaning devices, in particular to a cleaning device for scale on the side surface of continuously cast slabs. Background Art

[0002] During the continuous casting production process, after the continuously cast slab undergoes secondary cooling, a layer of scale will be generated on its surface due to the temperature rise. If it is not cleaned, the slab number sprayed by the subsequent manipulator spray number machine on the side surface (spray number working surface) of the slab will be incomplete or unclear due to the shedding of the scale.

[0003] Currently, in the prior art, sometimes a wire brush is used to brush the side surface of the slab. Although it can achieve the effect of cleaning the scale, since the slab still has a relatively high temperature, when the wire contacts the side surface of the slab, heat will be transferred to the wire and its temperature will rise rapidly, which makes the wire more prone to wear and greatly reduces the service life of the wire brush; therefore, in the actual production process, it is necessary to frequently replace the wire brush, which is rather troublesome. Summary of the Utility Model

[0004] Based on the above problems, the purpose of the utility model is to provide a cleaning device for scale on the side surface of continuously cast slabs to solve the problems existing in the above prior art.

One ends of the water outlet pipe and the water inlet pipe are respectively communicated with the water passing channels inside the heat conduction plate, and the other ends are respectively connected to a cooling water circulation machine.

[0009] Further, on the side of the heat conduction plate away from the wires, there is an installation sleeve. On the top of the support frame, there is an insertion plate adapted to the installation sleeve. After the insertion plate is inserted into the installation sleeve, it is detachably connected through a first bolt connection pair.

[0010] Furthermore, the water outlet pipe and the water inlet pipe are respectively connected with a conveying pipe through a union joint. The two conveying pipes are respectively arranged on the upper and lower sides of the insertion plate, and the ends of the two conveying pipes are respectively connected to the cooling water circulation machine through a connecting hose.

[0011] Furthermore, a plurality of pipe clamps for fixing the corresponding conveying pipes are arranged at intervals on both the upper and lower sides of the insertion plate.

[0012] Furthermore, a plurality of partition plates arranged in a staggered manner in sequence are arranged at intervals from top to bottom on the inner wall of the heat conduction plate, and the inner wall of the heat conduction plate and the plurality of partition plates together form the water passing channel.

[0013] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0014] By continuously conveying cooling water into the heat conduction plate, the present utility model can cool down the heat conduction plate, and then the heat conduction plate transfers the cold quantity to the steel wire, which can effectively reduce the temperature of the steel wire, thereby greatly slowing down the wear of the steel wire and improving its service life.

[0021] As Figures 1-3As shown in the figure, in this embodiment, a cleaning device for the scale on the side of a continuous casting slab is disclosed, which includes a support frame 1. The support frame 1 is arranged on one side of the conveying roller 10. A cooling guide plate 2 is detachably connected to the support frame 1. On one side of the cooling guide plate 2, multiple bundles of steel wires 3 for brushing the side of the slab 11 are fixed; at the upper and lower ends of the side of the cooling guide plate 2 away from the steel wires 3, a water outlet pipe 4 and a water inlet pipe 5 are respectively fixed. One ends of the water outlet pipe 4 and the water inlet pipe 5 are respectively communicated with the two ends of the water passing channel 201 inside the cooling guide plate 2, and the other ends are respectively connected to the cooling water circulation machine 12.

[0022] In this embodiment, the cooling water circulation machine 12 is used to cool the water inside it, and then convey it to the inside of the cooling guide plate 2 through the water inlet pipe 5. After flowing in the water passing channel 201 inside the cooling guide plate 2, it flows out through the water outlet pipe 4; the water flowing out then flows back into the inside of the cooling water circulation machine 12 to continue cooling; the cooling guide plate 2 is made of stainless steel.

[0023] It should be noted that the cooling water circulation machine 12 is a prior art, and its working principle and usage method are both known, so they will not be elaborated here.

[0024] Adopting this solution, by continuously conveying cooling water to the inside of the cooling guide plate 2, the cooling guide plate 2 can be cooled and its temperature can be reduced. Furthermore, the cooling guide plate 2 transfers the cold quantity to the steel wires 3, which can effectively reduce the temperature of the steel wires 3, thereby greatly slowing down the wear of the steel wires 3 and improving their service life.

[0025] In a further optimized solution, a mounting sleeve 202 is fixedly connected to the side of the cooling guide plate 2 away from the steel wires 3. A plug board 101 adapted to the mounting sleeve 202 is fixedly connected to the top of the support frame 1. After the plug board 101 is inserted into the mounting sleeve 202, it is detachably connected through a first bolt connection pair.

[0026] In this embodiment, through holes 6 are arranged at intervals from top to bottom on both the mounting sleeve 202 and the plug board 101. The number of the first bolt connection pairs is the same as the number of through holes 6 on the plug board 101. After the first connecting bolt in the first bolt connection pair passes through the mounting sleeve 202 and the plug board 101 through the through hole 6, it is locked and fixed through a first locking nut and a first washer.

In this embodiment, the union joint 7 is set as a threaded union joint, and the two ends of the union joint 7 are respectively threadedly connected with the conveying pipe 8 and the water outlet pipe 4 or the water inlet pipe 5.

[0028] Further optimization solution: A plurality of pipe clamps 9 for fixing the corresponding conveying pipes 8 are fixedly connected at intervals on both the upper and lower sides of the insertion plate 101. By providing the pipe clamps 9, the conveying pipes 8 can be fixed.

[0029] Further optimization solution: A plurality of partition plates 203 arranged in a staggered manner in sequence are fixedly arranged at intervals from top to bottom on the inner wall of the heat conduction plate 2. The inner wall of the heat conduction plate 2 and the plurality of partition plates 203 together form a water passing channel 201. By providing the plurality of partition plates 203, the flowing time of the cooling water in the water passing channel 201 is prolonged.

[0030] Further optimization solution: Two corresponding clamping plates 13 are arranged on the side of the heat conduction plate 2 away from the mounting sleeve 202. One of the clamping plates 13 is fixedly connected to the outer wall of the heat conduction plate 2 by welding and is connected to the other clamping plate 13 through a second bolt connection pair; the two clamping plates 13 jointly clamp and fix a plurality of bundles of steel wires 3.

[0031] In this embodiment, both of the two clamping plates 13 are made of stainless steel. A plurality of corresponding connection holes 14 are provided on both the two clamping plates 13 from top to bottom. The number of the second bolt connection pairs is the same as the number of the connection holes 14 on one of the clamping plates 13; after the second connection bolts in the second bolt connection pairs penetrate through the corresponding connection holes 14, they are locked and fixed through second locking nuts and second washers.
