Abstract
Description
Technical Field
[0001] This invention relates to the field of descaling devices, and in particular to a high-efficiency descaling device. Background Technology
[0002] Metal descaling (also known as descaling or peeling) is a key process in metal processing to remove surface oxide scale. It aims to improve surface quality, remove oxide layers (such as rust, oxides, etc.) formed during hot rolling, forging, or heat treatment, and prevent surface defects (such as roughness, coating peeling).
[0003] Mechanical descaling removes oxides by directly contacting the metal surface with a rotating scraper or wire brush. Its main technical drawbacks are: Torque control inaccuracy: When processing slabs with thickness deviations exceeding ±5%, traditional mechanical devices lack adaptive adjustment capabilities, leading to excessive contact between the scraper and the substrate. Statistics from an aluminum processing company show that under such conditions, the motor overload accident rate reaches 18%, and the synchronous belt breakage frequency is as high as 0.7 times / week. Surface damage risk: When the hardness of the wire brush filaments is not properly matched with the metal substrate, scratches are easily formed on the surface. Surveys show that the surface roughness Ra value of cold-rolled steel sheets descaled using traditional mechanical methods is 30%-50% higher than the required value, forcing companies to add polishing processes, increasing the cost per ton by 80-120 yuan. Low maintenance efficiency: Replacing the brush requires disassembling 8-12 fixing bolts, with a single operation taking more than 45 minutes and requiring two technicians, directly affecting the overall equipment efficiency (OEE) index. Furthermore, there is no equipment available for efficient descaling of cylindrical materials.
[0004] However, existing high-pressure water descaling methods often suffer from incomplete descaling and insufficient resource utilization when used for cylindrical steel and forged steel (materials).
[0005] Therefore, there is an urgent need for a new, highly efficient descaling device to solve the above problems. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art and achieve the above-mentioned functions, the present invention provides a highly efficient descaling device.
[0007] This invention is achieved through the following technical solution: A high-efficiency descaling device includes a descaling steel cylinder vertically fixed on a second base plate. The descaling steel cylinder has a conveying slot on its right side. It also includes a vertically arranged conveying chain with several conveying supports fixed at intervals on the conveying chain. The conveying supports can enter the descaling steel cylinder through the conveying slot and move downward therein. On the left side of the descaling steel cylinder, there are several sets of high-pressure descaling components arranged vertically. The high-pressure descaling components include descaling slots located on the descaling steel cylinder. Each set of descaling slots consists of several slots in the horizontal direction. Each descaling slot is equipped with a horizontal high-pressure nozzle. The spray direction of the horizontal high-pressure nozzle is the same direction that causes the material to rotate along the vertical axis. The upper surface of the conveyor tray is inclined, and the inclination direction is such that the material in the descaling steel cylinder falls towards the inner left wall. The conveyor tray is provided with a water trough b that runs vertically through it.
[0008] Furthermore, a top high-pressure nozzle is installed vertically at the upper end of the descaling steel cylinder, and the top high-pressure nozzle is connected to a water pump assembly c fixed on the outer wall of the descaling steel cylinder.
[0009] Furthermore, the uppermost end of the descaling steel cylinder is provided with an exhaust bend with a bent pipe structure, and an exhaust fan is installed at the end face of the exhaust bend.
[0010] Furthermore, the second base plate is fixedly connected to the first base plate below it by support columns at the four corners, and the descaling steel cylinder passes through the second base plate and is connected to the bent discharge pipe below it. The discharge pipe is located between the first base plate and the second base plate. The bottom of the discharge pipe is provided with a vertically penetrating water trough a, and the discharge pipe is clamped and fixed in the waste residue water box below it. The waste residue water box is connected to the high-temperature waste heat recycling device through an output pipe.
[0011] Furthermore, the upper left end of the descaling steel cylinder is provided with a feed pipe connected to it. The end of the feed pipe is higher than the high-pressure descaling component and lower than the top high-pressure nozzle. The inner diameter of the feed pipe is half the inner diameter of the descaling steel cylinder.
[0012] Furthermore, the horizontal high-pressure nozzle is connected to the outer high-pressure water supply pipe, which is fixed to a limiting bracket on the outer wall of the descaling steel cylinder, and is connected to the water pressure pump assembly a on the left side.
[0013] Furthermore, the bottom of the straight cylinder of the descaling steel cylinder is provided with two bottom through slots, and each bottom through slot is provided with an inclined upward bottom high-pressure nozzle, which is connected to the water pressure pump assembly b on the outside.
[0014] Furthermore, both the horizontal high-pressure nozzle and the bottom high-pressure nozzle are located outside the inner diameter of the descaling steel cylinder.
[0015] Furthermore, the conveying trough extends downwards below the second base plate, and the conveying chain is vertically fixed at the front and rear by bracket a and bracket b, respectively.
[0016] Furthermore, hemispherical protrusions are welded onto the conveyor to cause material imbalance.
[0017] The beneficial effects of this invention are: This invention can descale cylindrical materials from all angles, while effectively collecting water after descaling, filtering out residues, and reusing it. During the descaling process, the material is rotated, and multiple high-pressure jets can descale multiple times to ensure comprehensive descaling. The overall structure of this device facilitates loading and unloading, making it convenient for workers to fill and remove materials. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0022] refer to Figures 1 to 8 The present invention includes a descaling steel cylinder 1 vertically fixed on a second base plate 402, which serves as the main channel for descaling material 8. The descaling steel cylinder 1 has a conveying slot 106 on its right side. It also includes a vertically arranged conveying chain 2, which is a conventional conveying chain. Several conveying supports 3 are fixed at intervals on the conveying chain 2 and can be connected by conventional bolts. This is existing technology and will not be described in detail here. The conveying supports 3 can enter the descaling steel cylinder 1 through the conveying slot 106 and move downward therein, that is, convey the material 8 to be descaled downward. On the left side of the descaling steel cylinder 1, several sets of high-pressure descaling components are arranged vertically. Each high-pressure descaling component includes descaling slots 106 located on the descaling steel cylinder 1. Each set of descaling slots 106 consists of several horizontally arranged slots. Each descaling slot 106 is equipped with a horizontal high-pressure nozzle 5 for descaling the surface of the cylindrical material 8. The spray direction of the horizontal high-pressure nozzle 5 is the same direction that causes the material to rotate along its vertical axis. (Refer to...) Figure 5 This causes the material to rotate counterclockwise and descaling is performed during the process. The upper surface of the conveyor tray 3 is inclined, and the inclination direction is such that the material in the descaling steel cylinder 1 falls towards the inner left wall. The conveyor tray 3 is provided with a water trough b301 that runs vertically through it, so that water can flow downwards and leak out.
[0023] The descaling steel cylinder 1 is vertically installed at the top with a top high-pressure nozzle 6, which can perform high-pressure water descaling on the top of the material 1 after feeding. The top high-pressure nozzle 6 is connected to a water pump assembly c601 fixed on the outer wall of the descaling steel cylinder 1, which controls the air pressure and supplies water.
[0024] The uppermost end of the descaling steel cylinder 1 is provided with an exhaust bend 701 with a bent pipe structure, and an exhaust fan 701 is installed at the end face of the exhaust bend 701. The bend design facilitates the liquefaction and fall of water vapor upon contact with the wall. The exhaust fan 701 can discharge the remaining heat to prevent overheating. Of course, the exhaust bend 701 can be connected to a heat collection device for recycling.
[0025] The second base plate 402 is fixedly connected to the first base plate 4 below by the support columns 401 at the four corners.

The discharge pipe 103 is located between the first base plate 4 and the second base plate 402. The bottom of the discharge pipe 103 is provided with a vertically penetrating water trough a104 for collecting wastewater and filtering some residue. The discharge pipe 103 is snapped and fixed in the waste residue water box 105 below it. The waste residue water box 105 is connected to the high-temperature waste heat recycling device through the output pipe 107.
[0026] The upper left end of the descaling steel cylinder 1 is provided with a feed pipe 102 connected to it. The end of the feed pipe 102 is higher than the high-pressure descaling component and lower than the top high-pressure nozzle 6 to avoid interference with the feed. The inner diameter of the feed pipe 102 is half the inner diameter of the descaling steel cylinder 1 to prevent the material diameter from being too large to rotate or getting stuck in the channel.
[0027] refer to Figure 3 The horizontal high-pressure nozzle 5 is connected to the outer high-pressure water supply pipe 501. The high-pressure water supply pipe 501 is fixed to the limiting bracket 502 on the outer wall of the descaling steel cylinder 1. The high-pressure water supply pipe 501 is connected to the water pressure pump assembly a503 on the left side.
[0028] The bottom of the straight cylinder of the descaling steel cylinder 1 is provided with two bottom through slots 506, and each bottom through slot 506 is provided with a bottom high pressure nozzle 504 tilted upward. The bottom high pressure nozzle 504 is connected to the water pressure pump assembly b505 on the outside.
[0029] The horizontal high-pressure nozzle 5 and the bottom high-pressure nozzle 504 are both located outside the inner diameter of the descaling steel cylinder 1 to prevent material damage.
[0030] The conveying slot 101 extends downwards below the second base plate 402.
[0031] refer to Figure 7 The conveyor tray 3 is welded with a hemispherical protrusion 302 to make the material 8 unbalanced, which makes point contact with the bottom of the material 8 to facilitate its rotation under scouring.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
