[0034] In the related art, the nozzle of the header is easily damaged, and there is a structure of protecting the header with a protective pipe, but this structure is more complex to prepare, and the nozzle of the header itself still needs to be replaced as a whole due to water erosion, and there is a technical problem of damaging the nozzle of the header and affecting the descaling effect. The embodiments of the present application provide a header assembly and a descaling box assembly, which can at least solve the above technical problems to some extent.

[0035] The present application will be described below with reference to the accompanying drawings:

[0036] Figure 1 The structure of a header assembly in some embodiments or certain embodiments of the present application is shown, Figure 2 The cross-sectional view of a header assembly in some embodiments or certain embodiments of the present application is shown, referring to Figure 1 、 2 The embodiments of the present application provide a header assembly, which comprises:

[0037] The header 1 is closed at one end and has an entering end 11 at the other end.

[0038] A plurality of nozzles 2 are detachably connected to the header 1 and are all communicated to the pipe holes of the header 1.

[0039] Two rows of protective pieces 3 are connected to the outer peripheral wall of the header 1 along the circumferential direction of the header 1, each row of protective pieces 3 is arranged and distributed along the axial direction of the header 1, and the nozzles 2 are all located between the two rows of protective pieces 3.

[0040] The manifold 1 with one end closed and the other end as the entering end 11 can be installed on the equipment requiring descaling, high-pressure water enters the manifold 1 from the entering end 11, and then is sprayed out from the plurality of nozzles 2 in communication with the pipe holes of the manifold 1, to complete the high-pressure water spraying descaling. Since the nozzles 2 are detachably connected with the manifold 1, the nozzles 2 can be replaced in the case of being eroded and damaged by high-pressure water, to ensure the spraying descaling effect of the high-pressure water, and there are two rows of protective pieces 3 spaced apart along the circumference of the manifold 1 and connected with the outer circumferential wall of the manifold 1 in the manifold assembly, each row of protective pieces 3 is arranged along the axial direction of the manifold 1, and the nozzles 2 are located between the two rows of protective pieces 3. Since the manifold 1 is usually arranged across the slab 100, the positional relationship between the protective pieces 3 and the manifold 1 is arranged as above, which can effectively protect the nozzles 2, reduce the probability of the nozzles 2 being hit by the slab 100, and also will not affect the outflow of high-pressure water in the nozzles 2, to ensure the pressure of the high-pressure water flowing out of the nozzles 2 to ensure the descaling effect on the slab 100, and to a certain extent, solve the technical problem that the damage of the nozzle openings of the manifold 1 affects the descaling effect.

[0041] In the present application, since the nozzles 2 are replaceable, in the case of being eroded by water flow, only the nozzles 2 need to be replaced, and the water flow pressure at the nozzles 2 can be ensured. The structure is simple, the integration is high, the overall service life is long, and maintenance is also convenient.

[0042] It should be noted that each row of protective pieces 3 includes a plurality of protective pieces 3 arranged along the axial direction of the manifold 1. Figure 1 The structure of the nozzles 2 is not shown in the manifold, Figure 2 The structure of the nozzles 2 is shown in the manifold.

[0043] In some or certain embodiments, the two rows of protective pieces 3 protrude from the manifold 1 along the same radial direction of the manifold 1.

[0044] Each row of protective pieces 3 protrudes from the manifold 1 along the same radial direction of the manifold 1, and the protection effect on the nozzles 2 is better, and the space required by the protective pieces 3 and the manifold 1 as a whole will be smaller.

[0045] In some or certain embodiments, with the outer circumferential wall of the manifold 1 as a height reference, the two rows of protective pieces 3 have a height difference relative to the outer circumferential wall of the manifold 1.

[0046] With the outer circumferential wall of the manifold 1 as a height reference, the two rows of protective pieces 3 have a height difference relative to the outer circumferential wall of the manifold 1, and the nozzles 2 can be located on the side of the protective piece 3 with a smaller height relative to the outer circumferential wall of the manifold 1. This arrangement facilitates the rotation of the manifold 1 to adjust the nozzles 2 to be inclined, and facilitates the inclined arrangement of the nozzles 2 to improve the descaling effect on the slab 100.

[0047] In some or certain embodiments, two rows of guards 3 can also be arranged protruding from the header 1 in different radial directions, for example, two rows of guards 3 can also be connected to the header 1 in a spreader shape, and the height of the two rows of guards 3 relative to the outer peripheral wall of the header 1 can also be the same. It can also play a protective role for the nozzles 2.

[0048] In some or certain embodiments, the guards 3 can be blocks protruding from the header 1, or can also be columnar or plate-shaped. They can all play a certain protective role for the nozzles 2.

[0049] In some or certain embodiments, the header 1 can include:

[0050] A tubular body 12, one end is closed, and the other end is configured as an inlet end 11.

[0051] A plurality of tubular ejection portions 13 corresponding to the plurality of nozzles 2, the ejection portion 13 is fixedly connected with the body 12 and one end is detachably connected with the nozzle 2, and the tube hole of the ejection portion 13 communicates the tube hole of the nozzle 2 with the tube hole of the body 12.

[0052] The tubular body 12 of the header 1 can supply high-pressure water, and the tube hole of the ejection portion 13 communicates the tube hole of the nozzle 2 with the tube hole of the body 12, so that the ejection portion 13 can transmit the high-pressure water entering the body 12 to the nozzle 2 through its own tube hole, and the high-pressure water is ejected from the nozzle 2, facilitating the transmission and ejection of high-pressure water.

[0053] In some or certain embodiments, the ejection portion 13 is inserted into the body 12 and the outer peripheral wall is fixedly connected with the body 12, and the other end of the ejection portion 13 is located in the tube hole of the body 12.

[0054] The other end of the ejection portion 13 is located in the tube hole of the body 12, the strength of the ejection portion 13 is a little higher, the ejection portion 13 is not easy to tilt and shake relative to the body 12, and the strength of the whole header 1 is improved.

[0055] In some or certain embodiments, the depth of the other end of the ejection portion 13 inserted into the body 12 can be one-third to one-half of the overall length of the ejection portion 13, the strength of the header 1 is higher, and the overall use effect is better.

[0056] In some or certain embodiments, one end of the body 12 of the header 1 can be welded with an end plate to be closed, and the inlet end 11 of the body 12 can also be provided with a flange 14.

[0057] In some or certain embodiments, the spray part 13 can also be connected with the body 12 and the nozzle 2 at two ends respectively. One end of the spray part 13 is welded and fixed with the body 12 and communicated with the pipe hole of the body 12. The other end of the spray part 13 is detachably connected with the nozzle 2 and communicated with the nozzle 2. The flow of high-pressure water can be realized, and the nozzle 2 can be replaced conveniently.

[0058] It should be noted that the body 12 is provided with a through hole 121 which is communicated with the pipe hole of the spray part 13 and the pipe hole of the body 12. The high-pressure water in the pipe hole of the body 12 flows to the pipe hole of the spray part 13 through the through hole 121 and then flows to the nozzle 2. The nozzle 2 can also be detachably connected with the through hole 121 formed in the body 12. The present application does not limit this.

[0059] In some or certain embodiments, the plurality of spray parts 13 are distributed along the axial direction of the body 12. The nozzles 2 connected with the spray parts 13 correspondingly can also be distributed along the axial direction of the body 12. If the length direction of the header 1 is arranged along the width direction of the slab 100, the pressure of the high-pressure water sprayed from the nozzles 2 is relatively consistent, and the cleaning effect of the nozzles 2 on the slab 100 is better.

[0060] In some or certain embodiments, the extension arrangement direction of the plurality of spray parts 13 can also have a certain angle with the axial direction of the body 12. The cleaning of the slab 100 can also be realized.

The V-shaped part 15 can support and fix the spray part 13, ensure the positional accuracy of the spray part 13 relative to the body 12, ensure the stable spraying of the high-pressure water, and be beneficial to improve the descaling effect. A certain space can also be formed between the V-shaped part 15 and the outer peripheral wall of the body 12, which can play a certain buffering and damping role, is also beneficial to improve the service life of the header 1 as a whole, and improve the long-term descaling effect.

[0064] In some or certain embodiments, the V-shaped part 15 is connected and fixed with the two rows of protection pieces 3.

[0068] The box body 4 is provided with a passage 41 through which the slab 100 passes.

[0069] At least two header assemblies as described above are connected with the box body 4 and are respectively located on both sides of the passage 41, and the nozzles 2 are all directed towards the passage 41.

The box body 4 can provide installation space for the header assembly, and the passage 41 of the box body 4 can be used for the slab 100 to pass through. The at least two header assemblies are connected with the box body 4 and are respectively located on both sides of the passage 41, and the nozzles 2 in the header assemblies are all directed towards the passage 41. Therefore, when the slab 100 passes through the passage 41, the nozzles 2 on both sides of the passage 41 can spray high-pressure water to the two slab surfaces of the slab 100 respectively, thereby ensuring the effective descaling of the slab 100.

[0071] In some or certain embodiments, the descaling box assembly can comprise an even number of header assemblies, and the even number of header assemblies can be distributed in pairs on both sides of the passage 41. The installation position of the header 1 relative to the descaling box can be adjusted so that the spray opening of the nozzle 2 has an included angle with the running direction of the slab 100.
