Description

Technical Field

[0001] The utility model relates to a sinking roller with a flow-guiding function, belonging to the technical field of molten zinc bath equipment. Background Art

[0002] At present, the zinc bath in the zinc pot heats the molten zinc groove through the induction body to promote the convection of the zinc liquid and make the zinc bath flow. However, due to the poor fluidity of the zinc liquid, it can only flow in a local range, which has little effect on the overall flow of the zinc bath in the zinc pot. The poor fluidity of the zinc liquid will cause the Al element to float on the surface of the zinc liquid and increase the zinc slag. In addition, some alloy elements such as Sb, Ni, and Bi in the zinc bath have poor fluidity, causing local segregation and restricting the performance of the alloy elements. In addition, the sinking roller in the prior art is generally made of 316L material, which has poor wear resistance, thereby affecting the service life of the sinking roller. Utility Model Content

[0003] The utility model aims to solve the problem that the performance of alloy elements is restricted due to poor fluidity of zinc bath in the existing zinc pot, and further provides a sinking roller with a diversion function.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A submerged roller with a diversion function comprises a roller body, end covers fixedly mounted at both ends of the roller body and a plurality of guide plates arranged inside the roller body, wherein each guide plate is integrally fixedly mounted on the inner wall of the roller body and is arranged obliquely.

[0006] Furthermore, a plurality of guide plates are evenly distributed along the circumference of the roller body.

[0007] Furthermore, the inclination angle of each guide plate relative to the axis direction of the roller body is 25°.

[0008] Furthermore, the number of guide plates is three.

[0009] Furthermore, each guide plate has a length of 761 mm, a width A along the radial direction of the roller body of 20 mm, and a thickness along the radial direction of the roller body of 40 mm.

[0010] Furthermore, the roller body is made of tungsten-cobalt alloy.

[0011] Furthermore, the guide plate is made of 316 stainless steel.

[0012] Furthermore, annular limiting clamping platforms are respectively provided on the inner walls of the two ends of the roller body, and the two end covers are correspondingly axially limited by the annular limiting clamping platforms.

[0013] Furthermore, the inner walls of both ends of the roller body are respectively provided with a plurality of slots along the circumference thereof, and one end of the end cover is provided with a plurality of limit blocks along the circumference thereof, and the plurality of limit blocks are correspondingly and cooperatingly arranged in the plurality of slots.

[0014] Furthermore, the outer circumferential surface of the roller body is processed with a plurality of annular grooves along its axial direction.

[0015] Compared with the prior art, the utility model has the following effects:

[0016] In the utility model, a plurality of guide plates are added inside the sinking roller, so that the strip steel drives the sinking roller to rotate while stirring the zinc bath through the plurality of guide plates, so that the zinc bath generates axial flow along the guide plates, thereby increasing the fluidity of the zinc bath, thereby making the alloy components of the zinc bath more evenly distributed, reducing the generation of zinc slag, and making full use of the aluminum element and antimony element in the zinc liquid.

[0017] The guide plate in the utility model is integrally fixed inside the roller body. During the operation of the equipment, since the strip steel runs under tension, the friction between the strip steel and the sinking roller drives the sinking roller to rotate, so there is no need to operate the sinking roller separately to achieve the function of stirring the zinc liquid.

[0029] Specific implementation method 1: Combination Figure 1-5 This embodiment is explained, and the technical scheme in the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] It should be noted that the descriptions of the present invention regarding directions such as "front", "back", "left", "right", "inside", "outside", "left side", "right side", "upper", "lower", "top", "bottom", etc. are all defined based on the relationship between the orientations or positions shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure described must be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] A submerged roller with a diversion function comprises a roller body 1, end covers 2 fixed at both ends of the roller body 1, and a plurality of guide plates 3 arranged inside the roller body 1, wherein each guide plate 3 is integrally fixed on the inner wall of the roller body 1 and is arranged obliquely.

[0033] The number of the guide plates 3 may be two, three or more, preferably three guide plates 3, which are evenly distributed along the circumference of the sinking roller to achieve a better guide effect.

[0034] The guide plate 3 and the roller body 1 can be connected by welding.

[0035] The two end covers 2 are inserted into the two ends of the roller body 1, and the connection between the end covers 2 and the roller body 1 is preferably welding.

[0036] In the utility model, a plurality of guide plates 3 are added inside the sinking roller, so that the strip steel drives the sinking roller to rotate while stirring the zinc bath through the plurality of guide plates 3, so that the zinc bath generates axial flow along the guide plates 3, thereby increasing the fluidity of the zinc bath, and further making the alloy components of the zinc bath more evenly distributed, reducing the generation of zinc slag, and making full use of the aluminum element and antimony element in the zinc liquid.

[0037] The guide plate 3 in the utility model is integrally fixed inside the roller body 1. During the operation of the equipment, since the strip steel runs under tension, the friction between the strip steel and the sinking roller drives the sinking roller to rotate. Therefore, there is no need to operate the sinking roller separately to achieve the function of stirring the zinc liquid.

[0038] The guide plates 3 are evenly distributed along the circumference of the roller body 1. Such a design further ensures that the zinc bath alloy components are more evenly distributed.

[0039] The inclination angle β of each guide plate 3 relative to the axis direction of the roller body 1 is 25°. Such a design can achieve a better stirring effect on the zinc bath in the roller body 1.

[0040] The number of the guide plates 3 is three. Such a design can reduce the overall weight of the sinking roller while ensuring the fluidity of the zinc bath.

[0041] Each guide plate 3 has a length of 761 mm, a width A along the radial direction of the roller body 1 of 20 mm, and a thickness along the radial direction of the roller body 1 of 40 mm. In this way, by designing the size of the guide plate, the weight of the entire sinking roller can be reduced while ensuring the stirring effect of the zinc bath.

[0042] The material of the roller body 1 is tungsten-cobalt alloy. Such a design effectively increases the wear resistance of the roller body 1, thereby extending the service life of the sinking roller.

[0043] The guide plate 3 is made of 316 stainless steel.

[0044] The inner walls of the two ends of the roller body 1 are respectively provided with annular limiting clamping platforms 4, and the two end covers 2 are correspondingly axially limited by the annular limiting clamping platforms 4. In this design, the installation limit position of the end cover 2 on the roller body 1 is limited by setting the annular limiting clamping platforms 4.

[0045] The outer circumferential surface of the roller body 1 is processed with a plurality of annular grooves 7 along its axial direction.

[0046] Specific implementation method 2: Combination Figure 1-3 , Figure 6-9In this embodiment, the inner walls of the two ends of the roller body 1 are respectively provided with a plurality of slots 5 along the circumference thereof, and one end of the end cover 2 is provided with a plurality of limit blocks 6 along the circumference thereof, and the plurality of limit blocks 6 are correspondingly provided in the plurality of slots 5. With such a design, the two end covers 2 are correspondingly limited in the axial direction and the circumferential direction by the plurality of limit blocks 6 and the plurality of slots 5. The number of the slots 5 is the same as the number of the limit blocks 6. The other components and connection relationships are the same as those of the first embodiment.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
