Description

Technical Field

[0001] This utility model relates to the field of submerged roller technology, specifically a submerged roller for low-noise operation. Background Technology

[0002] Low-noise operation submerged rollers are a key equipment component used on continuous hot-dip galvanizing production lines, mainly for controlling the surface quality of steel strips and improving production efficiency and product quality.

[0003] Submerged rollers are an important component in continuous hot-dip galvanizing production lines. They operate while immersed in molten zinc and are driven by the friction between the steel strip and the roller surface. This process is crucial to the surface coating quality of the steel strip and production efficiency.

[0004] In continuous hot-dip galvanizing production lines, the submerged rolls are in direct contact with highly corrosive molten zinc for extended periods, inevitably suffering from corrosion. This not only affects the structural stability of the submerged rolls but also causes imbalance in the center of gravity during rotation. When the submerged rolls come into contact with the surface of the steel strip, this imbalance will generate significant mechanical noise, which will propagate along the cylinder wall of the submerged rolls, further amplifying the noise level. Therefore, a submerged roll with low noise operation is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a submerged roller with low noise operation, in order to solve the problem that the submerged roller is damaged due to long-term contact with corrosive zinc liquid, resulting in mechanical noise when in contact with the steel strip, which is amplified and propagates along the cylinder wall.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A low-noise operation submerged roller includes a submerged roller drum, with sealing caps threaded to both ends of the submerged roller drum. A metal sealing ring is sandwiched between the sealing cap and the submerged roller drum. A sound-absorbing component is provided on the inner side of the submerged roller drum. A main shaft is fixedly connected to the outer side of the sealing cap. The sound-absorbing component includes a contact groove, which is formed on the inner wall of the submerged roller drum. A sound-insulating cylinder is provided inside the submerged roller drum. A collection cover is fixedly connected to the surface of the sound-insulating cylinder. A support box is fixedly connected to the outer side of the sound-insulating cylinder. A mounting box is fixedly connected to the top of the support box. A sound-absorbing cotton layer is fitted inside the mounting box. A sound-absorbing plate is fitted inside the support box. A sound-absorbing cotton column is fitted on the inner wall of the sound-insulating cylinder. A positioning rail is fixedly connected to the outer side of the contact groove. The positioning rail and the mounting box slide against each other.

[0008] As a further optimization of this utility model, at least four sets of contact grooves and at least four sets of sound-absorbing cotton layers are provided. The contact grooves and sound-absorbing cotton layers correspond one-to-one, and the inner wall of each set of contact grooves is in contact with the surface of the sound-absorbing cotton layer.

[0009] As a further optimization of this utility model, the following features are provided: a plurality of collection covers are provided, the plurality of collection covers are arranged in a horizontal direction, the cross-section of the collection covers is tapered, and the collection covers are connected to the interior of the sound insulation cylinder.

[0010] As a further optimization of this utility model, at least four sets of support boxes and at least four sets of mounting boxes are provided, with a one-to-one correspondence between the support boxes and mounting boxes, and the mounting boxes being connected to the sound insulation cylinder through the support boxes.

[0011] As a further optimization of this utility model, the sound-absorbing panel has a rectangular cross-section, the top end of the sound-absorbing panel abuts against the bottom end of the sound-absorbing cotton layer, and the bottom end of the sound-absorbing panel is in contact with the surface of the sound-absorbing cotton column.

[0012] As a further optimization of this utility model, the sound insulation cylinder is provided with sound insulation caps at both ends, and the inner side of the sound insulation caps is in contact with the outer side of the sound-absorbing cotton column.

[0013] As a further optimization of this utility model, a rubber column is fixedly connected to one side of each of the two sealing caps. The rubber column and the sealing cap are located on the same central axis, and one end of the rubber column is in contact with the surface of the soundproof cap.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by setting a sealing cover, the molten zinc can be effectively prevented from entering the cylinder wall, thereby avoiding corrosion of the inner wall. At the same time, the contact groove of the sound-absorbing component allows the sound-absorbing cotton layer to fit tightly, which is beneficial for absorbing the noise generated when the submerged roller comes into contact with the steel strip. In this process, the sound-absorbing cotton layer transmits the residual sound to the sound-absorbing plate, which then guides it to the sound-absorbing cotton column. Finally, the sound-absorbing cotton column is used to further absorb the noise, forming a multi-stage noise reduction effect, which greatly reduces the propagation of noise on the cylinder wall. In addition, the sound-absorbing component adopts an easy-to-disassemble design, which facilitates the maintenance and replacement of the sound-absorbing material, ensuring that the submerged roller maintains low-noise operation for a long time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A low-noise operation submerged roller includes a submerged roller 1, with sealing caps 2 threaded to both ends of the submerged roller 1. A metal sealing ring 3 is sandwiched between the sealing cap 2 and the submerged roller 1. A sound-absorbing component 4 is provided on the inner side of the submerged roller 1, and a main shaft 5 is fixedly connected to the outer side of the sealing cap 2. The sound-absorbing component 4 includes a contact groove 41, which is formed on the inner wall of the submerged roller 1. A sound-insulating cylinder 42 is provided inside the submerged roller 1, and a collection cover 43 is fixedly connected to the surface of the sound-insulating cylinder 42. A support box 44 is fixedly connected to the outer side of the sound-insulating cylinder 42, which improves the internal support of the submerged roller 1. At least four sets of support boxes 44 and at least four sets of mounting boxes 45 are provided. The support boxes 44 and mounting boxes 45 are connected together. The components are arranged in a one-to-one correspondence. The mounting box 45 is connected to the sound insulation cylinder 42 through the support box 44. The top of the support box 44 is fixedly connected to the mounting box 45. The interior of the mounting box 45 is fitted with a sound-absorbing cotton layer 46, which is made of glass fiber material and has good sound absorption and heat insulation properties. The interior of the support box 44 is fitted with a sound-absorbing plate 47, which is made of porous foam material. The inner wall of the sound insulation cylinder 42 is fitted with a sound-absorbing cotton column 48, which is made of polyester fiber material. The outer side of the contact groove 41 is fixedly connected to a positioning rail 411, which slides with the mounting box 45. This arrangement facilitates the maintenance and replacement of the sound-absorbing material and ensures that the submerged roller maintains low-noise operation for a long time.

[0026] As a further implementation of this scheme, at least four sets of contact grooves 41 and at least four sets of sound-absorbing cotton layers 46 are provided. The contact grooves 41 and the sound-absorbing cotton layers 46 correspond one-to-one. The inner wall of each set of contact grooves 41 is in contact with the surface of the sound-absorbing cotton layers 46. This arrangement is conducive to absorbing the noise generated when the submerged roller 1 contacts the steel belt.

[0027] As a further implementation of this scheme, several collection covers 43 are provided, and the several collection covers 43 are arranged in a horizontal direction. The cross-section of the collection cover 43 is conical, and the collection cover 43 is connected to the interior of the sound insulation cylinder 42. This arrangement is conducive to the collection of sound.

[0028] As a further implementation of this solution, the sound-absorbing panel 47 has a rectangular cross-section. The top of the sound-absorbing panel 47 abuts against the bottom of the sound-absorbing cotton layer 46, and the bottom of the sound-absorbing panel 47 is in contact with the surface of the sound-absorbing cotton column 48. This arrangement of the sound-absorbing cotton layer 46 can also transmit the residual sound to the sound-absorbing panel 47, which then guides it to the sound-absorbing cotton column 48. Finally, the sound-absorbing cotton column 48 is used to absorb the noise, resulting in a better sound absorption effect.

[0029] As a further implementation of this solution, soundproof covers 421 are provided at both ends of the soundproof cylinder 42. The inner side of the soundproof cover 421 is attached to the outer side of the sound-absorbing cotton column 48. This arrangement facilitates maintenance.

[0030] As a further implementation of this solution, rubber pillars 21 are fixedly connected to the corresponding sides of the two sealing covers 2. The rubber pillars 21 and the sealing covers 2 are located on the same central axis. One end of the rubber pillar 21 is in contact with the surface of the soundproof cover 421. This arrangement uses the rubber pillars 21 to limit the position of the soundproof cover 421 and the soundproof cylinder 42, without the need for additional connecting parts.

[0031] Work process: The submerged roller 1 and the sealing cover 2 are connected by threads, with the thread direction opposite to the rotation direction of the submerged roller 1 to prevent accidental detachment. The addition of the metal sealing ring 3 further enhances the sealing performance between the submerged roller 1 and the sealing cover 2. In order to reduce noise, the sound-absorbing cotton layer 46 has good sound absorption and heat insulation properties. The inner wall of the submerged roller 1 is specially designed with a contact groove 41, so that the sound-absorbing cotton layer 46 can fit tightly with the submerged roller 1. In this way, the noise generated when the submerged roller 1 contacts the steel strip can be effectively absorbed by the sound-absorbing cotton layer 46. In addition, the sound-absorbing cotton layer 46 can also transmit the residual sound to the sound-absorbing plate 47, and then the sound-absorbing plate 47 guides it to the sound-absorbing cotton column 48, and finally the sound-absorbing cotton column 48 is used to absorb the noise.

[0032] Between each pair of adjacent support boxes 44, noise can be absorbed by the sound-absorbing cotton column 48 inside the sound insulation cylinder 42 through the collection cover 43. The cross-section of the collection cover 43 is designed to be conical, which is conducive to sound collection. The noise is then transmitted to the sound-absorbing cotton column 48 for absorption. In order to maintain the noise reduction effect of the submerged roller 1, the sound-absorbing cotton layer 46 and the sound-absorbing cotton column 48 need to be replaced regularly. The replacement process is simple and convenient. The operator only needs to remove the sealing cover 2 at one end to pull out the sound insulation cylinder 42 and the mounting box 45 connected by the support box 44 from the positioning rail 411 to replace the sound-absorbing cotton layer 46. After removing the sound insulation cover 421, the sound-absorbing cotton column 48 can be replaced. After the replacement is completed, the mounting box 45 is simply slid into the corresponding positioning rail 411 so that the sound-absorbing cotton layer 46 fits tightly with the contact groove 41, ensuring the convenience of installation and maintenance.

[0033] 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.
