Description

Technical Field

[0001] The utility model relates to the technical field of degreasing special-shaped steel wires, and more particularly to an online high-pressure steam degreasing production line suitable for special-shaped steel wires. Background Art

[0002] Special-shaped steel wires must be free of oil on their surface during the production process or upon delivery. This is because oil on the surface of special-shaped steel wires can cause scratches on the steel wire during dry powder drawing, or prevent film formation during surface coating, etc.; or because oil on the surface of cold-rolled stainless steel special-shaped steel wires can cause the surface of the steel wire to turn black and produce oil smoke during subsequent low-temperature processing, affecting product quality while also polluting the environment. There are two traditional ways to degrease special-shaped steel wires: one is to clean the surface oil by adding chemical reagents; the other is to degrease the surface of the steel wire by contact. The first chemical degreasing method is often accompanied by the generation of waste residue, which puts enormous pressure on environmental protection; the second contact degreasing method inevitably has the problem of wear, and the degreasing is not thorough and unstable, and is prone to generating waste. Therefore, there is an urgent need to design a degreasing device that can achieve high efficiency, non-destructiveness and environmental protection to solve the above-mentioned existing technical problems. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the above-mentioned existing technologies and to provide an online high-pressure steam degreasing production line for special-shaped steel wires. The utility model can not only smoothly destroy the oil film on the surface of the special-shaped steel wire, but also protect the surface quality of the special-shaped steel wire, achieving efficient and non-destructive degreasing of the surface of the special-shaped steel wire, improving the degreasing efficiency and degreasing quality; after degreasing and drying, the surface of the special-shaped steel wire is dry, which can effectively prevent the steel wire from rusting; at the same time, the cleaned oil can be easily separated and recovered, which can be recycled and reused, reducing oil consumption and costs, and effectively avoiding oil pollution and reducing the generation of waste.

[0004] The purpose of this utility model can be achieved through the following technical measures:

[0005] The utility model is an online high-pressure steam degreasing production line for special-shaped steel wire, which comprises a pay-off device, an inlet positioning wheel group, a high-pressure steam box, an outlet positioning wheel group, a drying device, and a take-up device, which are arranged in sequence according to the forward movement direction of the special-shaped steel wire (the pay-off device is used to pay-off the special-shaped steel wire; the inlet positioning wheel group cooperates with the outlet positioning wheel group to achieve the height positioning of the special-shaped steel wire; the special-shaped steel wire passes through the high-pressure steam box, and the high-temperature and high-pressure characteristics of the high-pressure steam are used to impact the surface of the special-shaped steel wire to destroy the oil film on the surface of the special-shaped steel wire, thereby achieving efficient and non-destructive degreasing of the surface of the special-shaped steel wire; the degreased special-shaped steel wire is dried by the drying device to evaporate the moisture remaining in the steam on the surface of the special-shaped steel wire, so that the surface of the special-shaped steel wire is kept dry, thereby effectively preventing the steel wire from rusting; the take-up device is used to take-up the special-shaped steel wire); the high-pressure steam box comprises an upper sealing The stepped shell consists of a cavity and a lower sealed cavity, and two rows of upper and lower high-pressure nozzles are arranged in an upper and lower symmetrical manner in the upper sealed cavity and connected to the external steam supply pipe (so that in the process of the special-shaped steel wire passing through the high-pressure steam box, high-pressure steam is ejected from the upper and lower rows of high-pressure nozzles respectively, and the high temperature and high pressure characteristics of the high-pressure steam are used to impact the surface of the special-shaped steel wire, which can not only successfully destroy the oil film on the surface of the special-shaped steel wire, but also protect the surface quality of the special-shaped steel wire, achieve efficient and non-destructive degreasing of the surface of the special-shaped steel wire, and improve the degreasing efficiency and degreasing quality); an oil-water reflux hole is opened on the interface between the upper sealed cavity and the lower sealed cavity (the cleaned oil and the steam-condensed water flow into the lower sealed cavity through the oil-water reflux hole. Since oil and water do not merge, they are easy to separate, so that the recovered oil can be recycled, reducing oil consumption, reducing costs, and effectively avoiding oil pollution and reducing the generation of waste).

[0006] The high-pressure nozzle described in the present invention is in the shape of a truncated cone, and the opposite ends of the upper and lower rows of high-pressure nozzles are both small-mouth ends (the outlet end is smaller than the inlet end, which is convenient for pressurized injection), and the injection range is larger than the width of the special-shaped steel wire (to ensure that the injection range can cover the cross-section of the special-shaped steel wire and avoid injection dead angles).

[0007] The horizontal symmetry axes of the upper and lower rows of high-pressure nozzles, the inlet positioning wheel group, and the outlet positioning wheel group described in the present invention are all collinear at the same height and are flush with the top tangent line of the pay-off wheel of the pay-off device and the top tangent line of the take-up wheel of the take-up device (that is, it is ensured that the upper and lower rows of high-pressure nozzles, the inlet positioning wheel group, and the outlet positioning wheel group all use the horizontally forward-moving special-shaped steel wire as the symmetry axis and are symmetrically arranged above and below the special-shaped steel wire, ensuring that the positioning pressure and spray impact force on the upper and lower surfaces of the special-shaped steel wire are uniform, and maintaining uniformity of force on the upper and lower sides of the special-shaped steel wire).

[0008] The design principle of this utility model is as follows:

[0009] The utility model is designed with a high-pressure steam box, in which two rows of high-pressure nozzles connected to an external steam supply pipe are arranged in an upper and lower symmetrical manner in an upper sealed chamber of the high-pressure steam box. In this way, when the special-shaped steel wire passes through the high-pressure steam box, high-pressure steam is ejected from the upper and lower rows of high-pressure nozzles respectively, and the surface of the special-shaped steel wire is impacted by the high temperature and high pressure characteristics of the high-pressure steam. This can not only successfully destroy the oil film on the surface of the special-shaped steel wire, but also protect the surface quality of the special-shaped steel wire, achieve efficient and non-destructive degreasing of the surface of the special-shaped steel wire, and improve the degreasing efficiency and degreasing quality; the special-shaped steel wire after degreasing is then dried by a drying device, and the moisture remaining in the steam on the surface of the special-shaped steel wire is evaporated, so that the surface of the special-shaped steel wire remains dry, thereby effectively preventing the steel wire from rusting; at the same time, the cleaned oil and the water condensed by the steam flow into the lower sealed chamber through the oil-water reflux hole. Since the oil and water do not mix, the oil and water are easily separated, so that the recovered oil can be further recycled, thereby reducing oil consumption and cost, and effectively avoiding oil pollution and reducing the generation of waste.

[0010] The beneficial technical effects of the present utility model are as follows:

[0011] The utility model can not only smoothly destroy the oil film on the surface of the special-shaped steel wire, but also protect the surface quality of the special-shaped steel wire, realize high-efficiency and non-destructive degreasing of the surface of the special-shaped steel wire, and improve the degreasing efficiency and degreasing quality; the surface of the special-shaped steel wire after degreasing and then drying is dry, which can effectively prevent the steel wire from rusting; at the same time, the oil after cleaning is easy to separate and recover, which can be further recycled, thereby reducing oil consumption and cost, and can also effectively avoid oil pollution and reduce the generation of waste.

[0014] The utility model is further described below with reference to the accompanying drawings:

[0015] like Figure 1As shown, the utility model is a production line for online high-pressure steam degreasing of special-shaped steel wire, which includes a pay-off device 1, an inlet positioning wheel group 3, a high-pressure steam box 4, an outlet positioning wheel group 5, a drying device 6, and a take-up device 7 arranged in sequence according to the forward movement direction of the special-shaped steel wire 2 (the pay-off device 1 is used to pay off the special-shaped steel wire 2; the inlet positioning wheel group 3 and the outlet positioning wheel group 5 cooperate to achieve the height positioning of the special-shaped steel wire 2; the special-shaped steel wire 2 passes through the high-pressure steam box 4, and the high-temperature and high-pressure characteristics of the high-pressure steam are used to impact the surface of the special-shaped steel wire 2 to destroy the oil film on the surface of the special-shaped steel wire, thereby achieving efficient and non-destructive degreasing of the surface of the special-shaped steel wire; the degreased special-shaped steel wire 2 is dried by the drying device 6 to evaporate the residual moisture on the surface of the special-shaped steel wire 2, so that the surface of the special-shaped steel wire 2 remains dry, thereby effectively preventing the steel wire from rusting; the take-up device 7 is used to take up the special-shaped steel wire 2); the high-pressure steam box 4 includes an upper sealed chamber 4-1-1 and a lower sealed chamber 4-2-2. The sealed chamber 4-1-2 is composed of a stepped shell 4-1, and two upper and lower rows of high-pressure nozzles 4-2 are arranged in an upper and lower symmetrical manner in the upper sealed chamber 4-1-1 and connected to the external steam supply pipe (so that when the special-shaped steel wire 2 passes through the high-pressure steam box 4, high-pressure steam is ejected from the upper and lower rows of high-pressure nozzles 4-2 respectively, and the high temperature and high pressure characteristics of the high-pressure steam are used to impact the surface of the special-shaped steel wire 2. This can not only successfully destroy the oil film on the surface of the special-shaped steel wire, but also protect the surface quality of the special-shaped steel wire, achieve efficient and non-destructive degreasing of the surface of the special-shaped steel wire, and improve the degreasing efficiency and degreasing quality); an oil-water reflux hole is opened on the interface between the upper sealed chamber 4-1-1 and the lower sealed chamber 4-1-2 (the cleaned oil and the steam-condensed water flow into the lower sealed chamber 4-1-2 through the oil-water reflux hole. Since oil and water do not mix, they are easy to separate, so that the recovered oil can be recycled, reducing oil consumption and costs, and can also effectively avoid oil pollution and reduce the generation of waste).

[0016] The high-pressure nozzle 4-2 described in the present invention is in the shape of a truncated cone, and the opposite ends of the upper and lower rows of high-pressure nozzles 4-2 are both small-mouth ends (the outlet end is smaller than the inlet end, which is convenient for pressurized injection), and the injection range is greater than the width of the special-shaped steel wire 2 (to ensure that the injection range can cover the cross-section of the special-shaped steel wire 2 and avoid the occurrence of injection dead angles).

[0017] The horizontal symmetry axes of the upper and lower rows of high-pressure nozzles 4-2, the inlet positioning wheel group 3, and the outlet positioning wheel group 5 in the present invention are all collinear at the same height and are flush with the top tangent line of the pay-off wheel of the pay-off device 1 and the top tangent line of the take-up wheel of the take-up device 7 (that is, the upper and lower rows of high-pressure nozzles 4-2, the inlet positioning wheel group 3, and the outlet positioning wheel group 5 are all symmetrically arranged above and below the shaped steel wire 2 with the horizontally forward-moving special-shaped steel wire 2 as the symmetry axis, ensuring that the upper and lower surfaces of the special-shaped steel wire 2 are subjected to uniform positioning pressure and uniform spray impact force, and maintaining uniformity of force on the upper and lower sides of the special-shaped steel wire 2).

[0018] The specific usage of this utility model is as follows:

[0019] After being paid out by the pay-out device 1, the shaped steel wire 2 passes through the inlet positioning wheel assembly 3, the high-pressure steam box 4, the outlet positioning wheel assembly 5, and the drying device 6 in sequence before being taken up by the take-up device 7. The inlet positioning wheel assembly 3 and the outlet positioning wheel assembly 5 cooperate with each other to achieve the height positioning of the shaped steel wire 2. When the shaped steel wire 2 passes through the high-pressure steam box 4, the high-temperature and high-pressure characteristics of the high-pressure steam impact the surface of the shaped steel wire 2, destroying the oil film on the surface of the shaped steel wire, thereby achieving efficient and non-destructive degreasing of the surface of the shaped steel wire. The degreased shaped steel wire 2 is then dried by the drying device 6 to evaporate the residual moisture on the surface of the shaped steel wire 2, keeping the surface of the shaped steel wire 2 dry, thereby effectively preventing the steel wire from rusting. At the same time, the cleaned oil and the condensed water from the steam flow into the lower sealed chamber 4-1-2 through the oil-water return hole. Since the oil and water do not mix, they are easily separated. In this way, the recovered oil can be further recycled, reducing oil consumption and costs, and effectively avoiding oil pollution and reducing the generation of waste.
