Description

Technical Field

[0001] The utility model belongs to the technical field of rolling production equipment, and particularly relates to a self - suction type aerosol cooling device for a high - speed wire laying tube. Background Art

[0002] The wire laying machine is one of the key equipment for high - wire production. After the wire rod is finish - rolled, it needs to be laid into coils by the wire laying machine to complete the transformation from a straight piece to a coil. The wire laying machine mainly consists of several parts such as a gear transmission part, a straight conduit, a hollow shaft, and a wire laying tube. Among them, the wire laying tube is a vulnerable part of the wire laying machine equipment. The structure of the wire laying tube is in the shape of an Archimedes spiral. The wire laying tube is installed on the wire laying head with a cantilever structure and is driven by the wire laying machine to rotate at a high speed. The high - temperature wire rod products during the rolling process are converted from a straight state to a circular state and output through the straight conduit and the hollow shaft. At present, the temperature of the wire rod after finish - rolling is relatively high. After entering the wire laying tube, the heat will be immediately transferred to the wire laying tube. Affected by the high - temperature heat, during the wire laying process, the wire laying tube is prone to serious heat - induced deformation and relatively serious wear. Therefore, on - line cooling treatment of the wire laying tube is required. In the existing technology, the cooling of the wire laying tube is carried out by mixing gas and liquid in a mixing tube and then spraying the aerosol mixture after mixing to cool the wire laying tube. This structure of the cooling device has the following deficiencies in the process of use. First, the liquid enters the mixing tube by self - suction to mix with the compressed gas. The gas and liquid cannot be mixed evenly, and the sprayed aerosol will contain water droplets, which cannot cool the wire laying tube evenly. The water droplets dripping onto the wire laying tube will affect the cooling effect. Second, the liquid directly enters the mixing tube without filtration treatment, and in the process of use, there will be a phenomenon of blockage of the nozzles at the end of the mixing tube. Therefore, it is objectively necessary to develop a self - suction type aerosol cooling device for a high - speed wire laying tube with a simple structure, better use effect, and not easy to block. Summary of the Invention

[0003] The purpose of the utility model is to provide a self - suction type aerosol cooling device for a high - speed wire laying tube with a simple structure, better use effect, and not easy to block.

[0004] The purpose of the utility model is realized as follows. It includes a wire laying machine, a wire laying tube, and an aerosol cooling assembly arranged above the wire laying machine. The aerosol cooling assembly includes an aerosol mixer, a liquid inlet pipe, a gas inlet pipe, and an aerosol pipe. The aerosol pipe is vertically installed on the upper part of the wire laying machine. A nozzle is arranged at the lower part inside the aerosol pipe. The aerosol mixer is installed at the upper end of the aerosol pipe. The gas inlet pipe is installed on one side of the aerosol mixer. The gas inlet pipe is connected to a gas storage tank through a gas inlet pipeline. A filter communicated with the aerosol mixer is installed at the top of the aerosol mixer. The liquid inlet pipe is installed above the filter. The liquid inlet pipe is connected to a liquid storage tank through a liquid inlet pipeline. A bypass pipe communicated with the gas inlet pipeline is installed on the aerosol pipe, and a bypass valve is installed on the bypass pipe.

[0005] Compared with the existing technology, the advantages of this device are as follows: First, an aerosol mixer is provided at the inlet end of the aerosol pipe. The provided aerosol mixer can uniformly and fully mix the liquid and gas entering the gas-liquid mixer to form aerosol particles. The formed aerosol particles are ejected through the nozzle at the end of the aerosol pipe, and the ejected aerosol can be uniformly sprayed on the outer wall of the spinning tube to achieve uniform cooling of the spinning tube and obtain a good cooling effect. Second, a filter is provided at the inlet of the gas-liquid mixer. The provided filter can filter the liquid entering the gas-liquid mixer, ensuring that the aerosol mixed in the gas-liquid mixer is uniformly and stably sprayed onto the spinning tube, preventing the nozzle from being blocked, and further improving the use effect. This device has the advantages of simple structure, uniform gas-liquid mixing, and not being easily blocked, and is easy to promote and use. Description of the Drawings

Detailed Embodiments

[0010] The present utility model will be further described below with reference to the drawings, but it is not limited to the present utility model in any way. Any change or improvement made based on the teachings of the present utility model falls within the protection scope of the present utility model.

[0011] As Figures 1 to 3As shown in the figure, the utility model includes a wire spitting machine 1, a wire spitting tube 2, and an aerosol cooling assembly arranged above the wire spitting machine 1. The structures of the wire spitting machine 1 and the wire spitting tube 2 are the structures used in the prior art. The aerosol cooling assembly includes an aerosol mixer 3, a liquid inlet pipe 4, an air inlet pipe 5, and an aerosol pipe 6. The aerosol pipe 6 is vertically installed on the upper part of the wire spitting machine 1. A nozzle 7 is arranged at the lower part inside the aerosol pipe 6. The nozzle 7 can adopt the structure used in the prior art. The aerosol mixer 3 is installed at the upper end of the aerosol pipe 6. The air inlet pipe 5 is installed on one side of the aerosol mixer 3. The air inlet pipe 5 is connected to a gas storage tank 9 through an air inlet pipeline 8. The gas storage tank 9 is filled with a compressed medium, and corresponding safety components such as a pressure gauge and a safety valve are equipped on the gas storage tank 9. The air inlet pipeline 8 includes an air inlet main pipe, an air pump and an air inlet valve installed on the air inlet main pipe. A filter communicated with the aerosol mixer 3 is installed at the top of the aerosol mixer 3. The liquid inlet pipe 4 is installed above the filter. The liquid inlet pipe 4 is connected to a liquid storage tank 11 through a liquid inlet pipeline 10. Cold water is stored in the liquid storage tank 11. Corresponding water replenishing pipes, liquid level gauges and other accessories are equipped on the liquid storage tank 11. The liquid inlet pipe includes a liquid inlet main pipe, a delivery pump and a liquid inlet valve installed on the liquid inlet main pipe. A bypass pipe 12 communicated with the air inlet pipeline 8 is installed on the aerosol pipe 6. A bypass valve is installed on the bypass pipe 12.

[0012] The working process of the present utility model is as follows: When the wire rod after finish rolling enters the laying head pipe 2, the liquid inlet pipeline 10 is controlled to convey the cold water in the liquid storage tank 11 into the liquid inlet pipe 4. The cold water enters the filter through the liquid inlet pipe 4 and then enters the gas-liquid mixer 3. At the same time when the cold water enters the gas-liquid mixer 3, the air inlet pipeline 8 is controlled to convey the compressed air in the gas storage tank 9 to the gas-liquid mixer 6 through the air inlet pipe 5. Since the compressed air entering the gas-liquid mixer 3 through the air inlet pipe 5 is a high-pressure gas-phase medium, when it sprays out through the air inlet pipe 5, the pressure energy is converted into kinetic energy, and the spraying speed from the air inlet pipe 5 can reach dozens of meters per second. The high-speed flowing compressed air shears, impacts and breaks the downward flowing liquid. When the external force (impact, frictional force) is greater than the internal force (surface tension, intermolecular attraction force), atomization occurs, so that the cold water and the compressed air entering the gas-liquid mixer 3 can be evenly mixed to form aerosol particles with uniform particle size. The formed aerosol particles flow downward along the aerosol pipe 6, and after flowing to the nozzle 7, they are evenly sprayed onto the surface of the laying head pipe 2 through the nozzle 7 to realize uniform cooling of the laying head pipe 2. When the wire rod after finish rolling completely passes through the laying head pipe 2, the liquid inlet pipeline 10 is controlled to stop conveying cold water to the liquid inlet pipe 4, and the air inlet pipeline 8 is controlled to stop conveying compressed air to the air inlet pipe 5. Then the control valve on the bypass pipe 12 is opened, and the compressed air in the gas storage tank 9 is sent into the aerosol pipe 6 through the bypass pipe 23, and the compressed air is used to blow into the laying head machine 1 through the nozzle 7 to perform cleaning treatment on the inside of the laying head machine 1. The structure of the bypass pipe 12 is adopted for cleaning the inside of the laying head machine 1, which can realize separate control of aerosol mixing and blowing cleaning, and the use effect will be better. The aerosol mixer 3 provided in this device can evenly and fully mix the liquid state and the gaseous state entering the gas-liquid mixer 3 to realize uniform cooling of the laying head pipe 2 and achieve a good cooling effect. The provided filter can filter the liquid entering the gas-liquid mixer 3, which can ensure that the aerosol mixed in the gas-liquid mixer 3 is evenly and stably sprayed onto the laying head pipe 2 and prevent the nozzle 7 from being blocked.

[0013] Further, in order to achieve a better gas-liquid temperature effect, the aerosol mixer 3 includes a mixer body and a bottom cover detachably installed at the lower part of the mixer body, which is convenient for replacing or cleaning the components inside the gas-liquid mixer and improves the convenience of use. There is an aerosol mixing cavity 301 that runs through the inside of the mixer body and the bottom cover. At the top of the aerosol mixing cavity 301 below the filter, a distribution cylinder 13 is installed. At the bottom of the distribution cylinder 13, a liquid distribution plate 14 is installed. A plurality of liquid distribution holes 15 are evenly distributed on the liquid distribution plate 14. The distribution cylinder 13 can evenly distribute the cold water entering the gas-liquid mixer 3, allowing the cold water to flow out through the plurality of liquid distribution holes 15. This can increase the contact area between the cold water and the compressed air and enable the cold water and the compressed air to be more fully mixed. Preferably, in order to achieve the even distribution of the cold water, the liquid distribution plate 14 has a structure with a thin edge and a thick middle. In order to improve the connection sealing performance between the mixer body and the bottom cover and prevent leakage, a sealing ring 302 is provided between the mixer body and the bottom cover. In order to increase the speed of the aerosol particles entering the aerosol tube 6 and achieve a better gas-liquid mixing effect, the inner cavity diameter of the aerosol mixing cavity 301 gradually decreases from top to bottom.

[0014] Further, the filter includes a filter box 16 and a filter tube 17. The filter tube 17 is disposed through between the filter box 16 and the aerosol mixer 3. A plurality of filter holes 18 are evenly machined on the tube wall of the filter tube 17 located inside the aerosol mixer 3. A sealing plate is installed at the bottom of the filter tube 17. Inside the upper end of the filter tube 17, a distribution block 19 is fixedly installed through a connecting rod. A downwardly concave distribution groove 20 is machined on the top surface of the distribution block 19. The lower end of the liquid inlet pipe 4 is located inside the distribution groove 20, and there is a certain gap between the liquid inlet pipe 4 and the bottom of the distribution groove 20. A sewage discharge pipe 21 is provided at the bottom of the filter box 16. During use, the cold water flowing out through the liquid inlet pipe 4 enters the distribution groove 20. After being distributed by the distribution groove 20, it flows downward along the tube wall of the filter tube 17. The cold water flowing into the bottom of the filter tube 17 is blocked by the sealing plate and then enters the aerosol mixer 3 through the filter holes 18. When the cold water enters the distribution groove 20, there will be a splashing phenomenon. The splashed cold water converges into the filter box 16. After using for a period of time, it can be discharged through the sewage discharge pipe 21. The provided filter tube 17 can filter the cold water and remove impurities in the cold water to prevent the nozzle 7 from being blocked. Preferably, in order to increase the flow rate of the cold water entering the aerosol mixer 3 and improve the gas-liquid mixing effect, the filter tube 17 has a conical structure with a large upper end and a small lower end.

[0015] Further, in order to increase the flow rate of the compressed air entering the gas-liquid mixer 3 and achieve a better gas-liquid mixing effect, a gas guiding block is installed inside the air inlet pipe 5 near the side of the aerosol mixing cavity 301. A gas guiding cavity is provided inside the gas guiding block, and the diameter of the gas guiding cavity gradually decreases along the air inlet direction.

[0016] Furthermore, a horn tube 22 is installed at the end of the aerosol tube 6 on the lower side of the nozzle 7. The horn tube 22 can gather the ejected aerosol particles so that all of them are blown onto the spinning tube 2, improving the effect of spray cooling on the spinning tube 2.
