Description

Technical Field

[0001] This utility model belongs to the field of steel wire processing technology, and specifically relates to a device for degreasing the surface of steel wire. Background Technology

[0002] During the steel wire production process, to facilitate drawing and form and for short-term rust prevention, the surface is usually coated with drawing powder, grease, or lubricant for lubrication, thereby reducing the friction experienced by the steel wire during stretching and preventing breakage. Before subsequent heat treatment, galvanizing, copper plating, and other deep processing, these greases must be thoroughly removed; otherwise, it will seriously affect the process quality and product performance.

[0003] Traditional degreasing methods mainly include the following: 1. Chemical alkaline washing: passing the steel wire through a high-temperature alkaline bath (such as sodium hydroxide solution); this method is energy-intensive (requires continuous heating), generates a large amount of waste alkaline solution, has high environmental treatment costs, and requires a large amount of water rinsing after cleaning, resulting in high overall costs. 2. Organic solvent cleaning: using solvents such as trichloroethylene for steam cleaning or soaking; this method has good cleaning effect, but the solvents are highly toxic, causing serious health risks to operators and environmental pollution, and its use is gradually being restricted.

[0004] In the prior art, such as the patent with publication number CN222931338U, a degreasing device for steel wire surface is disclosed, which removes grease by high-temperature sintering, reducing environmental pollution during steel wire manufacturing. However, in this solution, the steel wire stays for a short time during high-temperature sintering, and the steel wire may not be fully dried before proceeding to the next process, resulting in the lubricant not being completely solidified, affecting the subsequent polishing effect. At the same time, the heat generated by high-temperature sintering is dissipated in one go, resulting in low heat utilization and waste of resources.

[0005] Therefore, improvements are urgently needed. Utility Model Content

[0006] To address the aforementioned deficiencies in the existing technology, this utility model provides a degreasing device for steel wire surfaces, comprising a first steel wire brush roller group, a preheating mechanism, a heating mechanism, and a second steel wire brush roller group arranged sequentially along the processing and conveying direction of the steel wire. The preheating mechanism includes a preheating box, with five first inlets on the front side and five first outlets on the rear side, and the five first inlets and five first outlets respectively facing each other front and rear. Several first guide rollers are horizontally arranged inside the preheating box.

[0007] The heating mechanism includes a heating box and a hot air blower. Five second inlets are located on the front of the heating box, and these inlets are connected to five first outlets of the preheating box via connecting pipes. Five second outlets are located on the rear of the heating box, and these outlets are higher than the second inlets. The top of the heating box is connected to the top of the preheating box via a guide pipe, and an induced draft fan is installed on the guide pipe. Several second guide rollers are arranged in an S-shape inside the heating box. The hot air blower is located on the rear of the heating box, and its outlet is connected to five ventilation pipes. These five ventilation pipes correspond to the five second inlets and extend into the heating box, each equipped with multiple air blowing pipes. The ventilation pipes extend into the heating box and reach as far as possible between the second guide rollers. The outlets of the air blowing pipes face the location of the steel wire to blow as much hot air as possible onto the steel wire, accelerating the sintering and solidification of the lubricant on the steel wire surface.

[0008] Optionally, the first wire brush roller group includes a first upper wire brush roller and a first lower wire brush roller. The first upper wire brush roller is disposed at the front obliquely above the first lower wire brush roller, and the uppermost end of the first lower wire brush roller is higher than the lowermost end of the first upper wire brush roller.

[0009] Specifically, the first upper wire brush roller and the first lower wire brush roller are driven to rotate by the first drive motor, and the rotation direction of the first upper wire brush roller and the first lower wire brush roller is opposite to the travel direction of the wire.

[0010] Optionally, the second wire brush roller assembly includes a second upper wire brush roller and a second lower wire brush roller, wherein the second upper wire brush roller is disposed obliquely above the second lower wire brush roller, and the uppermost end of the second lower wire brush roller is higher than the lowermost end of the second upper wire brush roller.

[0011] Specifically, the second upper wire brush roller and the second lower wire brush roller are driven to rotate by the second drive motor, and the rotation direction of the second upper wire brush roller and the second lower wire brush roller is opposite to the travel direction of the wire.

[0012] Optionally, a first collection trough is provided below the first wire brush roller assembly.

[0013] Optionally, a second collection trough is provided below the second wire brush roller assembly.

[0014] Optionally, the first guide roller and the second guide roller are respectively provided with five first positioning grooves and five second positioning grooves, which are used to position the steel wire.

[0015] Specifically, the five first positioning grooves on the first guide roller correspond to the five first inlets, the five second positioning grooves on the bottommost second guide roller correspond to the five second inlets, and the five second positioning grooves on the topmost second guide roller correspond to the five second outlets.

[0016] Optionally, both the preheating chamber and the heating chamber are equipped with doors on their sides, and the doors are equipped with observation windows.

[0017] Specifically, the door facilitates maintenance of the preheating and heating chambers, while the observation window allows on-site personnel to monitor their operation.

[0018] In addition, the first lower wire brush roller, the first inlet, the first guide roller, the first outlet, the second inlet, and the second guide roller at the bottom are all at the same height to ensure that the wire passes through the preheating box and into the heating box smoothly; the second guide roller, the second outlet, and the second lower wire brush roller at the top are all at the same height to ensure that the wire passes through the heating box smoothly.

[0019] This invention also includes other components that enable the degreasing device for steel wire surfaces to function properly, all of which are conventional techniques in the field. Furthermore, any devices or components not specified in this invention employ conventional techniques in the field, such as induced draft fans and hot air blowers.

[0020] The working principle of this invention is as follows: Five steel wires are first passed through the first steel wire brush roller group. The first upper steel wire brush roller and the first lower steel wire brush roller can initially remove the lubricant from the surface of the steel wires. The brushed-off lubricant falls into the first collection tank and is collected. Then, the five steel wires pass through the preheating box and enter the heating box. The steel wires are conveyed from bottom to top around the second guide roller. The hot air fan is started to dry and heat the steel wires along the way. Since the second guide roller is S-shaped, the conveying distance of the steel wires is increased, so that the surface of the steel wires can be fully sintered. Afterwards, the steel wires exit from the second outlet of the heating box and pass through the second steel wire brush roller group. The second upper steel wire brush roller and the second lower steel wire brush roller can polish the solidified lubricant on the surface of the steel wires. The polished sintering powder falls into the second collection tank and is collected. Finally, the induced draft fan is started to draw the heat-exchanged hot air into the preheating box to preheat the subsequent steel wires, which facilitates the subsequent formal sintering process.

[0021] The beneficial effects of this utility model are that by setting an S-shaped second guide roller in the heating box, the conveying distance of the steel wire is increased, so that the surface of the steel wire can be fully sintered, which facilitates the subsequent grinding process; at the same time, the hot air after heat exchange is introduced into the preheating box to preheat the steel wire that enters later, which facilitates the subsequent formal sintering process, improves the heat utilization rate, and saves resources.

The ventilation pipes 12 are inserted into the heating box 6 and extend as far as possible between the second guide rollers 11. The air outlets of the air blowing pipes 13 are directed towards the location of the steel wire to blow as much hot air as possible onto the steel wire and accelerate the sintering and solidification of the lubricant on the surface of the steel wire.

[0031] The second wire brush roller assembly includes a second upper wire brush roller 14 and a second lower wire brush roller 15. The second upper wire brush roller 14 is positioned slightly above and behind the second lower wire brush roller 15, with the uppermost end of the second lower wire brush roller 15 higher than the lowermost end of the second upper wire brush roller 14. The second upper wire brush roller 14 and the second lower wire brush roller 15 are driven to rotate by a second drive motor, and the rotation direction of the second upper wire brush roller 14 and the second lower wire brush roller 15 is opposite to the direction of wire travel. A second collection groove 16 is correspondingly provided below the second wire brush roller assembly.

[0032] The first guide roller 5 and the second guide roller 11 are respectively provided with five first positioning grooves 17 and five second positioning grooves.
