Description

Technical Field

[0001] This utility model belongs to the field of steel wire rope production technology, and specifically relates to a straightener cleaning device for steel wire rope production. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the manufacturing process of conveyor belt wire rope, the straightener, as a key tool in the production of wire rope, has long faced the technical challenge of zinc powder deposition and dust pollution. Such surface contaminants not only cause the surface roughness of the wire rope to increase after being straightened by the straightener, but also damage the chemical activity of the zinc layer on the surface of the wire during the straightening process, reducing the bonding strength between the rubber and the wire rope, and seriously threatening the service life and safety performance of the conveyor belt wire rope product.

[0004] Currently, cleaning zinc powder deposits and dust contamination on straighteners usually requires operators to stop the machine, disassemble it, and manually clean it with a cleaning brush or hanging plate. This method takes a long time for each maintenance and significantly reduces the effective operating time of the production line. Moreover, after cleaning, a small amount of zinc powder particles will still remain on the roller surface of the straightener due to its arc-shaped structure. At this time, straightening will still affect the production quality of the wire rope. More seriously, frequent machine shutdowns and disassemblies accelerate the wear of the straightener bearings, which severely shortens the overhaul cycle and service life of the straightener.

[0005] Currently, there is a cleaning method that uses a centrifugal fan to perform negative pressure suction on the straightener. However, the suction duct is designed as a straight cylinder, and the turbulent airflow can easily cause zinc powder to settle, making it difficult to collect. In addition, the density of zinc powder is much higher than that of conventional dust, so a certain airflow speed needs to be maintained to achieve adsorption. In order to increase the adsorption efficiency, the power of the centrifugal fan needs to be increased, thereby increasing the operating cost. Utility Model Content

[0006] The purpose of this invention is to provide a cleaning device for a straightener used in wire rope production. This device uses an axial flow fan installed on one side of the straightener for non-disassembly negative pressure adsorption cleaning. The fan's suction port covers the entire axial length of the straightener and is located in the lower middle part directly opposite the straightener. Utilizing the gravity settling characteristics of zinc powder, it achieves full-range coverage and efficient dust capture. Combined with a variable-diameter guide channel, it achieves dust adsorption, transportation, and settling, making it easy to collect in a collection container. This results in efficient adsorption cleaning and collection of dust from the straightener.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] In a first aspect, an embodiment of the present invention provides a cleaning device for a straightener used in wire rope production, comprising a plurality of axial flow fans arranged side by side on one side of the straightener, wherein the air inlet of the axial flow fans faces the lower middle part of the straightener; the tail end of the axial flow fans is connected to a variable diameter guide channel, and the variable diameter guide channel is connected to a collection container.

[0009] The variable diameter guide channel is configured as a three-section variable diameter channel structure, and the air inlet end of the variable diameter guide channel connected to the axial flow fan is configured as a conical constriction structure.

[0011] As a further technical solution, the inlet section is connected to an axial flow fan, and the air inlet end of the inlet section connected to the axial flow fan is configured as a conical constriction structure. The other end of the inlet section is connected to a contraction section, the contraction section is connected to a slow flow section, and the slow flow section is connected to a collection container.

[0012] As a further technical solution, the diameter of the inlet section gradually decreases as it extends axially into the contraction section, and the diameter of the contraction section gradually increases as it extends axially into the slow-flow section.

[0013] As a further technical solution, the bottom of the axial flow fan is provided with a support frame, and the bottom of the support frame is provided with a moving mechanism.

[0014] As a further technical solution, the diameter of the air inlet of the axial flow fan is larger than the length of the straightener along the axial direction of the wire rope.

[0016] As a further technical solution, the variable diameter guide channel is made of aluminum foil tube; the middle section of the variable diameter guide channel is provided with spiral reinforcing ribs.

[0018] As a further technical solution, the collection container is made of woven bag, and the variable diameter guide channel is detachably connected to the woven bag through a clamp structure.

[0019] The beneficial effects of the above-described embodiments of this utility model are as follows:

[0020] The present invention provides a cleaning device for a straightener used in wire rope production, which can achieve full-range dust capture of the straightener. Through the low-position layout of the axial flow fan and the ultra-wide coverage design of the air inlet, a gravity-assisted directional adsorption flow field is constructed to achieve full-area capture of zinc powder falling off the roller surface of the straightener, completely eliminating the cleaning blind spots of traditional point adsorption.

[0021] An efficient dust transport system is constructed. The three-section variable diameter guide channel forms an airflow progression control mechanism that accelerates adsorption, stabilizes transport, and orderly settles, breaking through the technical bottleneck of high-density zinc powder being easy to settle and difficult to transport, and significantly reducing the residue on the inner wall of the pipeline.

[0028] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] Example 1

[0030] In a typical embodiment of this utility model, such as Figures 1 to 2 As shown, a cleaning device for a straightener used in wire rope production is provided, including several axial flow fans 1 arranged side by side on one side of the straightener 2. The air inlet of the axial flow fan 1 faces the lower middle part of the straightener 2. The tail end of the axial flow fan 1 is connected to a variable diameter guide channel 3, and the variable diameter guide channel 3 is connected to a collection container.

[0031] The variable diameter guide channel 3 is configured as a three-section variable diameter channel structure, and the air inlet end of the variable diameter guide channel 3 connected to the axial flow fan 1 is configured as a conical constriction structure 301.

[0032] By placing the axial flow fan 1 side-by-side on the side of the straightener 2, and precisely aligning the air inlet with the lower part of the straightener 2, the gravity settling characteristics of zinc powder are fully utilized to form a directional adsorption flow field, significantly expanding the dust capture range. The three-section structure design of the variable diameter guide channel 3 effectively balances the airflow velocity and pressure distribution, avoiding secondary settling of zinc powder caused by airflow turbulence in traditional straight pipes. The flared inlet design significantly reduces airflow inlet resistance, increases instantaneous airflow, and fundamentally improves the initial capture efficiency of high-density zinc powder.

[0033] As a further technical solution, the variable diameter guide channel 3 is configured as a three-section cylindrical structure consisting of an inlet section 302, a contraction section 303, and a slow-flow section 304.

[0034] As a further technical solution, the inlet section 302 is connected to the axial flow fan 1, and the air inlet end of the inlet section 302 connected to the axial flow fan 1 is set as a conical constriction structure 301. The other end of the inlet section 302 is connected to the contraction section 303, the contraction section 303 is connected to the slow flow section 304, and the slow flow section 304 is connected to the collection container.

[0035] As a further technical solution, the diameter of the inlet section 302 gradually decreases as it extends axially to the contraction section 303, and the diameter of the contraction section 303 gradually increases as it extends axially to the slow-flow section 304.

[0036] The three-stage variable diameter channel has a synergistic effect. The inlet section 302 adopts a conical constriction structure 301 to expand the airflow coverage area, so that the zinc powder falling off the roller surface of the straightener 2 is efficiently entrained into the airflow, avoiding the spread of dust around the equipment. The diameter of the contraction section 303 decreases, which accelerates the airflow and enhances the negative pressure intensity, generating a strong adsorption force on micron-sized zinc powder, solving the defect of insufficient adsorption force for high-density metal dust in traditional systems. The diameter of the slow flow section 304 gradually increases, which reduces the airflow speed and stabilizes the pressure field, promoting the orderly settling of zinc powder in the collection container and significantly reducing dust residue on the inner wall of the pipe.

[0037] The three-section structure of the inlet section 302, the contraction section 303, and the slow-flow section 304 forms a progressive airflow control of high-speed adsorption, stable conveying, and low-speed settling, breaking through the technical bottleneck of zinc powder being easy to settle and difficult to convey.

[0038] As a further technical solution, the axial flow fan 1 is provided with a support frame 4 at its bottom, and a moving mechanism 5 is provided at the bottom of the support frame 4. In this embodiment, the moving mechanism 5 can be a caster wheel with a self-locking structure. The support frame 4 provides a stable base for the axial flow fan 1, effectively suppressing equipment vibration during operation and ensuring the relative positional accuracy between the air inlet and the straightener 2. The moving mechanism 5 supports rapid adjustment of the fan position to adapt to the cleaning needs of straighteners 2 of different specifications, significantly improving the versatility of the device and its adaptability to production lines.

[0039] As a further technical solution, the diameter of the air inlet of the axial flow fan 1 is greater than the length of the straightener 2 along the axial direction of the wire rope.

[0040] The diameter of the air inlet is larger than the axial length of the straightener, achieving full-coverage adsorption of the roller surface working area and completely eliminating the blind spots in edge cleaning that exist in traditional point adsorption.

[0041] As a further technical solution, the end of the axial flow fan 1 near the straightener 2 is provided with a filter screen structure 6.

[0042] The filter screen has a dual protection mechanism, intercepting broken wires from the steel wire rope and large particles of impurities, preventing foreign objects from entering the fan and causing damage to the impeller.

[0043] As a further technical solution, the variable diameter guide channel 3 is made of aluminum foil tube; the middle section of the variable diameter guide channel 3 is provided with spiral reinforcing ribs.

[0044] The advantages of aluminum foil tubing include its flame-retardant properties, which eliminate the fire risk during zinc powder adsorption; its flexibility adapts to complex production line layouts, reducing installation difficulty. Spiral reinforcing ribs significantly improve the pipe's resistance to negative pressure deformation, ensuring that variable-diameter channels maintain their designed cross-sectional shape under high-speed airflow; and they suppress abnormal noises caused by pipe vibration, improving working environment comfort.

[0045] As a further technical solution, the contraction angle of the tapered constriction structure 301 is set between 10° and 20°.

[0046] The 10° to 20° contraction angle design provides low airflow resistance while preventing dust from accumulating at the port connection point and causing leakage, and avoiding significant leakage when the variable diameter guide channel 3 is removed. In this embodiment, a 15° contraction angle design is preferred.

[0047] As a further technical solution, the collection container is made of woven bag, and the variable diameter guide channel 3 is detachably connected to the woven bag through a clamp structure.

[0048] The woven bags are made of highly breathable material to ensure smooth airflow while efficiently trapping zinc powder; their low cost allows for large-scale replacement, meeting the consumable management needs of industrial scenarios.

[0049] The variable diameter guide channel 3 is detachably connected to the woven bag via a clamp structure, enabling tool-free and quick assembly and disassembly of the woven bag. Compared with traditional bolt connections, this shortens the replacement operation time. The sealed structure prevents dust leakage, ensuring zero pollution throughout the maintenance process.

[0050] The present invention provides a cleaning device for a straightener used in wire rope production, which can achieve full-range dust capture of the straightener 2. Through the low-position layout of the axial flow fan 1 and the ultra-wide coverage design of the air inlet, a gravity-assisted directional adsorption flow field is constructed to achieve full-area capture of zinc powder falling off the roller surface of the straightener 2, and completely eliminate the cleaning blind spots of traditional point adsorption.

[0051] An efficient dust transport system is constructed. The three-section variable diameter guide channel 3 forms an airflow progression control mechanism that accelerates adsorption, stabilizes transport, and orderly settles, breaking through the technical bottleneck of high-density zinc powder being easy to settle and difficult to transport, and significantly reducing the residue on the inner wall of the pipeline.

[0052] The filter screen is placed in front to prevent large particles and debris from being adsorbed and damaging the fan. The support frame 4 provides a stable base for the axial fan 1, effectively suppressing equipment vibration and ensuring the relative position accuracy of the air inlet and the straightener 2. The moving mechanism 5 supports quick adjustment of the fan position to adapt to the cleaning needs of straighteners 2 of different specifications, significantly improving the versatility of the device and the adaptability of the production line.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
