Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a cooling device for high-speed wire rods. Background Art

[0002] High-speed wire refers to wire steel rolled by high-speed rolling mills. High-speed wire is rolled by high-speed wire mills. The steel needs to be heated during the rolling process and then rolled after the heating is completed. The wire has a high temperature after rolling. In order to quickly coil and pack the rolled wire, the wire needs to be cooled. Currently, the more commonly used cooling methods are air cooling or water cooling and a combination of air cooling and water cooling. Air cooling or water cooling is relatively simple and has low cooling efficiency, while the combination of air cooling and water cooling has a higher cooling efficiency. However, during the cooling process, cold air can easily blow cooling water into the workshop, causing the humidity in the workshop to increase, which is not conducive to the health of workers. In addition, some oxides on the surface of the wire will fall off during the cooling process and will be blown into the air, affecting the environment and easily causing workers to inhale, endangering their health.

DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1 to 2 As shown, a cooling device for high-speed wire rods includes a conveyor 1, a mist collecting hood 2, a negative pressure pipe 3, a spray pipe 4 and a blower 5. A plurality of conveyor rollers are rotatably arranged on the conveyor 1 for conveying the rolled wire rods. A gap is left between two adjacent conveyor rollers for allowing cooling water and cold air to pass through. When the conveyor is conveying the wire rods, cooling water can be sprayed from the spray pipe 4 to cool the wire rods. Since the spray pipe 4 is located below the wire rods, in order to prevent the cooling water from falling on the ground, the blower 5 is arranged below the spray pipe 4 and blows cold air upwards. While the wire is cooled by air, cooling water can also be blown onto the wire for water cooling. After cooling, the air flow will move upward. In order to prevent the air flow from driving the water mist to blow into the workshop and causing the temperature and humidity in the workshop to rise, a mist collecting hood 2 is provided above the conveyor 1. Therefore, the air flow after passing through the wire and the water mist will be blocked by the mist collecting hood 2 when they move upward. After encountering the mist collecting hood 2, the water mist drips along the surface of the mist collecting hood 2. A negative pressure pipe 3 is connected to the mist collecting hood 2, and the air flow will be sucked by the negative pressure pipe 3 to prevent the air flow from dispersing. One end of the negative pressure pipe 3 is connected to an exhaust fan for sucking air.

[0029] Furthermore, the mist collecting hood 2 is a "human" shaped structure, and a water collecting trough 7 is provided at the lower end of the mist collecting hood 2. The bottom of the water collecting trough 7 is connected to a return water pipe 8. A return water tank is provided on one side of the conveyor 1. The return water tank is used for recycling and reusing condensed water. The return water pipe 8 is connected to the return water tank. In this embodiment, the water mist condenses after encountering the mist collecting hood 2 and can drip along the lower surface of the mist collecting hood 2 into the water collecting trough 7 for collection. The collected condensation can be collected into the return water tank through the return water pipe 8 for collection and reuse, thereby avoiding waste of water resources.

[0030] Furthermore, the conveyor 1 and the mist collecting hood 2 are fixedly connected by a support rod 6. There are multiple support rods 6. The support rods 6 are vertically arranged. One end of the support rod 6 is connected to the conveyor 1, and the other end is connected to the mist collecting hood 2.

[0031] In another embodiment, one end of the support rod 6 is hinged to the mist collecting hood 2 . When the conveyor 1 is to be maintained, the mist collecting hood 2 can be rotated to expose the conveyor 1 , thereby facilitating maintenance of the conveyor 1 .

[0032] Furthermore, if Figure 3 As shown, a cooling chamber 11 is provided in the mist collecting hood 2, and a cooling pipe 12 is fixedly provided in the cooling chamber 11. A water inlet pipe 9 and a water outlet pipe 10 are also fixedly provided on the mist collecting hood 2. The water inlet pipe 9 is connected to the input end of the cooling pipe 12, and the water outlet pipe 10 is connected to the output end of the cooling pipe 12. The water inlet pipe 9 and the water outlet pipe 10 are both connected to the return water tank. A water pump is provided on the water inlet pipe 9, and the return water tank is connected to a refrigerator. The refrigerator can cool the water in the return water tank, and the cooled water enters the cooling pipe 12 through the water inlet pipe 9 and is discharged from the water outlet pipe 10 and flows back into the return water tank. The spray water contacts the mist collecting hood 2 after passing through the wire to cool the wire. The cooling pipe can cool the water mist so that the water mist condenses into water droplets and drips into the water collecting tank 7 for collection.

[0033] Furthermore, the spray pipe 4 is provided with an atomizing nozzle 13, the nozzle of the atomizing nozzle 13 faces upward, and the cooling water is in a mist structure after being sprayed out by the atomizing nozzle 13, which facilitates the hair dryer 5 below to blow the atomized cooling water to the wire above for cooling.

[0034] Furthermore, a filter is provided in the negative pressure pipe 3 to filter the air flow sucked into the negative pressure pipe 3 .

[0035] Furthermore, the mist collecting hood 2 is provided with heat dissipation fins, which are located on the upper end surface of the mist collecting hood 2. The heat dissipation fins can quickly dissipate the heat on the mist collecting hood 2 to the outside, so that the temperature of the mist collecting hood 2 remains low.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
