Description

Technical Field

[0001] The invention belongs to the field of bare aluminum wire cooling devices, and in particular relates to a cooling atomization device for bare aluminum wire after continuous annealing. Background Art

[0002] As we all know, in the production process of copper-clad aluminum enameled wire, the bare aluminum wire needs to be continuously annealed, and the bare aluminum wire after continuous annealing needs to be cooled. At present, the annealing and cooling treatment of the bare aluminum wire after continuous annealing mainly adopts the method of cooling the bare aluminum wire with cooling water and then drying the surface moisture of the aluminum wire through an air drying pipe. Although this implementation mode can realize the cooling of the bare aluminum wire after annealing, it is easy to have the following defects:

[0003] 1) The cooling speed is slow, the cooling effect is poor, and the efficiency is low;

[0004] 2) Water droplets are likely to remain on the surface of the bare aluminum wire, affecting subsequent painting work;

[0005] 3) Bare aluminum wire is prone to scratches when passing through the air-drying duct, affecting the quality of painting. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved cooling atomization device for bare aluminum wire after continuous annealing.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0008] A cooling atomization device for a bare aluminum wire after continuous annealing, comprising a cooling chamber having a wire inlet and a wire outlet, an exhaust channel being formed on the cooling chamber, and the exhaust channel being arranged close to the wire inlet;

[0009] The cooling atomization device also includes a partition that divides the cooling chamber into a cooling zone and an atomization zone, an atomization generator connected to the atomization zone, and an exhaust fan connected to the exhaust channel, wherein the atomization zone and the cooling zone are connected at the end of the wire outlet, and the movement direction of the bare aluminum wire in the cooling zone is opposite to the flow direction of water mist from the atomization zone into the cooling zone.

[0010] Preferably, the atomization zone is located below the cooling zone, and the exhaust channel is located above the cooling zone. According to the principle of gas rising, the water mist can be quickly discharged from the exhaust channel after gasification, thereby achieving rapid heat exchange, and no water droplets or water stains will be formed on the surface of the bare aluminum wire.

[0011] According to a specific implementation and preferred aspect of the present invention, the atomizing generator includes a water supply assembly and a gas supply assembly connected to the atomizing zone, wherein water and gas converge in the atomizing zone to form water mist and enter the cooling zone from the outlet of the atomizing zone.

[0012] Specifically, the water supply assembly includes a plurality of high-pressure water spray pipes connected to the atomization area, and the gas supply assembly includes a plurality of baffles arranged in the atomization area and between the partition and the cooling chamber, wherein a gas channel is formed between the plurality of baffles. Under the baffle channels formed by the baffles, the generation of water mist is more favorable.

[0013] Furthermore, the air inlet of the gas channel is located below the line inlet, which is convenient for the entry of external air.

[0014] According to another specific implementation and preferred aspect of the present invention, a plurality of baffles are staggered and distributed up and down, and each baffle includes a vertical plate and a curved plate, wherein a baffle cavity is formed between the vertical plate and the curved plate, the opening of the baffle cavity located at the upper side faces upward, and the opening of the baffle cavity located at the lower side faces downward. The arrangement of the baffles is conducive to the generation of water mist and can effectively prevent the backflow of water mist.

[0015] Specifically, the baffle cavities of the plurality of baffles are all located on the side of the vertical plate facing the outlet, which has the best effect of preventing the water mist from flowing back.

[0016] In addition, the cooling atomization device further comprises a flow guide module arranged at the bottom of the partition, wherein the flow guide module is arranged close to the outlet of the atomization zone, which not only facilitates the upward movement of the water mist, but also facilitates the direction of the water mist in the cooling cavity.

[0017] Preferably, a sealing adjustment plate is provided at the wire inlet and the wire outlet, respectively. This arrangement can not only ensure the sealing of the cooling chamber, but also meet the requirements of bare aluminum wires with different outer diameters entering and exiting the cooling chamber.

[0018] Furthermore, the exhaust passage includes a first air duct extending obliquely upward from the top surface of the cooling chamber, and a second air duct extending vertically upward from the upper end of the first air duct, wherein the exhaust fan is connected to the second air duct. This arrangement accelerates the discharge of water vapor and prevents condensation into water droplets in the cooling chamber.

[0019] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0020] The present invention realizes rapid cooling of the bare aluminum wire by making the direction of the water mist in the cooling zone opposite to that of the bare aluminum wire, and quickly evaporates and takes away the heat when passing through the hot surface of the bare aluminum wire; at the same time, the water vapor in the cooling zone is extracted by the exhaust fan to prevent water droplets from remaining on the surface of the cooled bare aluminum wire, without affecting the subsequent painting process, and without the need to air-dry the surface of the bare aluminum wire, thereby ensuring the surface quality of the bare aluminum wire.

[0033] like Figure 1 As shown, the cooling atomization device for the bare aluminum wire after continuous annealing of this embodiment includes a cooling chamber 1, a partition 2, an atomization generator 3, and an exhaust fan 4, wherein the bare aluminum wire x passes through the cooling chamber 1 to the left from the wire inlet wheel x1 and then passes through the wire outlet wheel x2 to complete the cooling of the bare aluminum wire x.

[0034] Specifically, the cooling chamber 1 is formed with an inlet a1, an outlet a2 and an exhaust passage a3, wherein the outlet a2 and the inlet a1 are respectively arranged at the left and right ends of the cooling chamber 1, and the inlet a1 and the outlet a2 are aligned in the horizontal direction.

[0035] In this example, sealing adjustment plates b are provided at the inlet a1 and the outlet a2, respectively, so as to ensure the sealing of the cooling chamber.

[0036] The partition 2 extends horizontally from below the line inlet a1 toward the left side wall of the cooling chamber 1, and divides the cooling chamber 1 into a cooling zone q1 and an atomization zone q2, wherein the cooling zone q1 is located above the partition 2, the atomization zone q2 is located below the partition 2, and an outlet c of the atomization zone q2 is formed between the left end of the partition 2 and the left side wall of the cooling chamber 1.

[0037] That is, the moving direction of the bare aluminum wire x in the cooling zone q1 is opposite to the flow direction of the water mist from the atomizing zone q2 into the cooling zone q1.

[0038] The atomizing generator 3 includes a water supply assembly and a gas supply assembly which are connected to the atomizing zone q2, wherein water and gas converge in the atomizing zone to form water mist, and enter the cooling zone from the outlet of the atomizing zone.

[0039] Specifically, the atomizing generator 3 includes a high-pressure water spray pipe 30 and a baffle 31 located in the atomizing area q2.

[0040] In this example, there are five high-pressure water spray pipes 30, and the five high-pressure water spray pipes 30 are connected to the atomization area q2, and the water spray ports of the five high-pressure water spray pipes 30 connected to the atomization area q2 are located at the four corners and the center of the square. This arrangement has a good effect of forming water mist.

[0041] In this example, there are three baffles 31, two of which are vertically connected to the bottom surface of the cooling chamber 1, one baffle 31 is vertically connected to the bottom of the partition 2, and the three baffles 31 are staggered in the upper and lower parts.

[0042] Each baffle 31 includes a vertical plate 310 and a bent plate 311 fixedly disposed at one end of the vertical plate 310 .

[0043] In this example, the bent plate 311 is hook-shaped, and a baffle cavity q3 is formed between the vertical plate 310 and the bent plate 311, the opening of the baffle cavity q3 located at the top faces upward, and the opening of the baffle cavity q3 located at the bottom faces downward. The setting of the baffle is conducive to the generation of water mist and can effectively prevent the backflow of water mist.

[0044] It should be noted that the baffle chambers q3 of the three baffles 31 are all located on the side of the vertical plate 310 facing the outlet a2. At this time, the effect of preventing the backflow of water mist is the best.

[0045] In this example, three baffles 31 form a gas channel in the atomization zone q2, and the gas inlet of the gas channel is located below the line inlet a1.

[0046] At the same time, a flow guide module d is also provided at the bottom of the partition 2, and the flow guide module d is vertically connected to the bottom of the partition 2 from the left and right sides thereof, and the bottom surface of the flow guide module d is tilted downward from left to right and then horizontally extended, and the flow guide module d is provided close to the outlet c of the atomization area q2, which is not only convenient for the water mist to rise, but also more conducive to the direction of the water mist in the cooling chamber.

[0047] The exhaust channel a3 includes a first duct a30 and a second duct a31 connected to the end of the first duct a30, wherein the first duct a30 extends obliquely upward from the top surface of the cooling chamber 1 near the inlet a1, and the second duct a31 extends vertically upward from the upper end of the first duct a30.

[0048] In this example, the exhaust fan 4 is connected to the second air duct a31. This arrangement accelerates the discharge of water vapor and prevents condensation into water droplets in the cooling chamber.

[0049] The implementation process of this embodiment is as follows:

[0050] The bare aluminum wire x passes through the cooling chamber 1 from the inlet wheel x1 to the left and then passes through the outlet wheel x2. At the same time, the high-pressure water provided by the high-pressure water pipe below is mixed with the air entering from the outside to form water mist. After the water mist rises to the cooling chamber 1, it exchanges heat with the surface of the bare aluminum wire x. The water mist absorbs heat and evaporates. The evaporated gas is discharged from the exhaust channel a3 in the opposite direction of the movement of the bare aluminum wire x, thereby realizing rapid cooling of the surface of the bare aluminum wire x.

[0051] Therefore, this embodiment has the following advantages:

[0052] 1. The direction of the water mist in the cooling zone is opposite to that of the bare aluminum wire, and it evaporates quickly when passing through the hot surface of the bare aluminum wire and takes away the heat, and then is discharged from the exhaust channel to achieve rapid cooling of the bare aluminum wire;

[0053] 2. Prevent water droplets from remaining on the surface of the bare aluminum wire after cooling, which will not affect the subsequent painting process, and there is no need to air-dry the surface of the bare aluminum wire, thus ensuring the surface quality of the bare aluminum wire;

[0054] 3. The cost of water mist is low, and it can prevent the backflow of water mist. Under the negative pressure formed by an exhaust fan, it is conducive to the rapid flow of gas;

[0055] 4. The setting of the sealing adjustment plate effectively improves the sealing of the cooling chamber, is more conducive to the flow of gas, and improves the heat exchange efficiency and effect.

[0056] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
