Description

Technical Field

[0001] This application relates to the technical field of casting systems, and particularly to a device for draining steam in a casting system. Background Art

[0002] During the process of the liquid metal in a high-temperature state flowing through the crystallizer wheel and solidifying into a solid state, in order to ensure that the crystal structure of the ingot is dense and uniform, water spraying cooling is required. During this process, a large amount of steam is generated. At the same time, during the water spraying cooling process, the unevaporated water droplets will form liquid cooling water on the surface of the crystallizer wheel or around it.

[0003] Currently, generally, a vertical fan is used to blow the steam to prevent the steam from causing water vapor condensation on the surface of the product, which may affect the surface quality of the product.

[0004] However, the method of using a vertical fan to handle the steam cannot effectively control the diffusion of the steam, which may cause the steam to be blown towards the crystallizer wheel, making the surface of the crystallizer wheel wet, resulting in corrosion or damage to the surface of the crystallizer wheel, reducing the service life of the crystallizer wheel, and at the same time affecting the solidification speed and crystal quality of the metal during the crystallization process. Utility Model Content

[0005] This application provides a device for draining steam in a casting system to solve the problem that the diffusion of steam cannot be effectively controlled in the casting system, thereby improving the quality of the products produced by casting.

The crystallization wheel is arranged in the crystallization wheel placement cavity by being mounted on the rotating shaft. An arc-shaped cover plate is also provided on the inspection plate. When the inspection plate covers the inspection opening, the arc-shaped cover plate covers the rotating shaft.

[0036] As in the background art, the device for handling water vapor in the casting system in the related art has the problem that the diffusion of water vapor cannot be effectively controlled. Through research by the inventor, it is found that the reason for this problem is that the current method of using a vertical fan to blow away water vapor is relatively simple. The vertical fan is only directly arranged beside the crystallization wheel, and the water vapor is blown away by blowing. On the one hand, it will cause the water vapor to be blown towards the crystallization wheel and corrode the equipment. On the other hand, the blowing ability of the vertical fan is limited, and it cannot effectively handle a large amount of water vapor, resulting in the quality of the product being affected, and there may be potential safety hazards at the electrical equipment.

[0037] In view of the above technical problems, the embodiment of the present application provides a device for draining water vapor in a casting system. By setting a cover plate at the top of the crystallization wheel placement cavity and opening a crystallization wheel fixing port, the crystallization wheel fixing port is used to set the crystallization wheel in the crystallization wheel placement cavity and enable part of the wheel body to be located outside the cavity. The cover plate can prevent the water vapor generated during the casting process from entering the interior of the crystallization wheel placement cavity, resulting in the crystallization wheel being damp. And a wind channel is arranged in the crystallization wheel placement cavity and connected to a negative pressure fan. Thus, the water vapor generated can be collected through the air outlet arranged towards the crystallization wheel on the wind channel, thereby preventing the water vapor from adhering to the surface of the crystallization wheel, and using the negative pressure fan to pump air through the air duct for the wind channel, and then discharging the collected water vapor through the negative pressure fan, which can effectively prevent the diffusion of water vapor. At the same time, the wind channels are sequentially connected through telescopic hoses, so that the position of the wind channel can be adjusted according to the generation position of the water vapor, which is beneficial to improving the flexibility of the wind channel, and thus can be applicable to crystallization wheels of different sizes in different production environments, avoiding affecting the quality of the product.

[0038] In order to make the above objects, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0039] The embodiment of the present application provides a device for draining water vapor in a casting system, including a crystallization wheel placement cavity and a collection member. Among them, the collection member includes a wind channel and a negative pressure fan. The wind channel is arranged in the crystallization wheel placement cavity, which will not affect the casting process outside the crystallization wheel placement cavity, and at the same time can prevent the diffusion of water vapor and adsorption on the crystallization wheel.

[0040] Figure 1 For the structural schematic diagram of the device for draining water vapor in the casting system provided by the embodiment of the present application, as Figure 1As shown in the figure, the steam drainage device of the casting system provided by the embodiment of the present application includes:

[0041] A crystallizer wheel placement cavity 100, a cover plate 110 is provided at the top of the crystallizer wheel placement cavity 100, and a crystallizer wheel fixing port 111 is opened on the cover plate 110. Among them, the lower part of the crystallizer wheel 300 is arranged in the crystallizer wheel placement cavity 100 through the crystallizer wheel fixing port 111, and the upper part of the crystallizer wheel 300 is arranged outside the crystallizer wheel placement cavity 100;

[0042] The collection member 200 includes an air duct 210 and a negative pressure fan 220. The air duct 210 is arranged in the crystallizer wheel placement cavity 100, the air duct 210 is arranged close to the crystallizer wheel 300, and an air outlet 211 is also opened on the air duct 210. The air outlet 211 is arranged facing the crystallizer wheel 300. Among them, there are at least two air ducts 210, and the air ducts 210 are sequentially connected through a telescopic hose 230, and at least one air duct 210 is connected to the negative pressure fan 220 through an air duct 240.

[0043] When the liquid metal flows through the crystallizer wheel and solidifies into a solid state, the lower part of the crystallizer wheel 300 is fixed in the crystallizer wheel placement cavity 100 through the crystallizer wheel fixing port 111, and the upper part of the crystallizer wheel 300 is located outside the crystallizer wheel placement cavity 100. When the crystallizer wheel 300 is sprayed with water for cooling, a large amount of steam will be generated at the crystallizer wheel 300. At this time, the cover plate 110 covers the top of the crystallizer wheel placement cavity 100 to prevent the steam from entering the inside of the crystallizer wheel placement cavity 100. At the same time, the negative pressure fan 220 is started to generate a low pressure inside the negative pressure fan 220. Thus, the air is drawn out from the inside of the negative pressure fan 220, and through the air duct 240 connected to the negative pressure fan 220 and the air duct 210 connected to the air duct 240, the steam generated at the crystallizer wheel 300 can be inhaled into the air duct 210 through the air outlet 211 and flow to the negative pressure fan 220 until it is discharged. Among them, the air outlet 211 is arranged facing the crystallizer wheel 300, which can optimize the flow path of the steam, maximize the flow efficiency of the steam, reduce the resistance of the steam entering the air outlet 211, contribute to improving the overall performance of the negative pressure fan 220, and reduce energy consumption. In addition, the air duct 210 is arranged close to the crystallizer wheel 300 and is arranged inside the crystallizer wheel placement cavity 100, so that the steam generated at the crystallizer wheel 300 can be processed in time without affecting the casting process outside the crystallizer wheel placement cavity 100. And there are at least two air ducts 210, and the air ducts 210 are sequentially connected through a telescopic hose 230, so that the air duct 210 can move in the crystallizer wheel placement cavity 100. Since the steam generated at the crystallizer wheel 300 is not uniform, the air duct 210 can be moved to the position where more steam is generated to improve the steam discharge efficiency and prevent the steam from diffusing.

[0044] In a possible implementation manner, the air ducts 210 are arranged in a ring shape and are arranged around the crystallizer wheel 300.

[0045] According to the dimensions of the crystallization wheel 300, including diameter, thickness, etc., determine the number of air ducts 210, and arrange the air ducts 210 annularly around the crystallization wheel 300 to ensure that the air ducts 210 can cover the periphery of the crystallization wheel 300. Through the annularly arranged air ducts 210, the air flow around the crystallization wheel 300 can be made more uniform, thereby achieving uniform cooling of the product, improving the discharge efficiency of water vapor, preventing the diffusion of water vapor, being beneficial to controlling the temperature of the crystallization wheel 300, preventing local overcooling or overheating of the crystallization wheel 300, and ensuring the quality and consistency of the product.

[0046] In some embodiments, the number and position of the annularly arranged air ducts 210 can be adjusted according to specific process requirements, so as to achieve different cooling effects to adapt to different casting processes.

[0047] In order to further meet the different requirements of the water vapor discharge device for the casting process, in the embodiments of the present application, the air inlet 211 can be a spherical air inlet.

[0048] The spherical air inlet can be of a spherical or hemispherical structure, enabling water vapor to be introduced into the air inlet from multiple directions. Exemplarily, adjustable vanes can be provided inside the spherical air inlet, enabling water vapor to enter the air duct 210 evenly and allowing the air intake volume and air intake direction to be adjusted as needed, improving the flexibility of the air inlet 211 to enhance the water vapor inhalation effect.

[0049] In a possible implementation manner, both between the telescopic hose 230 and the air duct 210 and between the air pipe 240 and the air duct 210 are connected through a connection interface 250, and the connection interface 250 is detachably and fixedly connected to the air duct 210.

[0050] Through the connection interface 250, it can be ensured that water vapor can be transmitted from the air duct 210 to another air duct 210 through the telescopic hose 230, and from the air duct 210 to the air pipe 240, forming a continuous gas transmission path to prevent water vapor leakage. For example, when there are electrical equipment or high-temperature components, it can prevent electrical failures or unsafe working environments caused by water vapor leakage and reduce potential safety hazards.

[0051] Since the connection interface 250 is detachably and fixedly connected to the air duct 210, it is convenient for installation, disassembly, and maintenance between the air ducts 210 and between the air ducts 210 and the air pipe 240. At the same time, the air pipe 240 can be connected to any air duct 210 through the connection interface 250. Therefore, the position of the negative pressure fan 220 connected to the air pipe 240 can be adjusted according to the connection position between the air pipe 240 and the air duct 210 without affecting the operation of the entire water vapor discharge device.

[0052] It should be noted that in this embodiment, the connection method of the connection interface 250 can be threaded connection, flange connection, or other fixed connection methods, which will not be elaborated here.

[0053] In the embodiment of the present application, a sealing gasket 251 is provided at the connection interface 250.

[0054] Through the sealing gasket 251, not only can the possible gaps at the connection interface 250 be filled to prevent the leakage of cooling water from the interface, but also external pollutants can be prevented from entering the interior of the connection interface 250.

[0055] During the process of discharging water vapor, there may be a situation where there is too much water vapor and the exhaust port of the negative pressure fan 220 cannot discharge it all in time. Therefore, in this embodiment, an emergency discharge device 400 is also provided at the elbow of the air duct 240.

[0056] As an example, the emergency discharge device 400 can be a device such as an exhaust valve or a pressure relief valve. When the effect of the negative pressure fan 220 in pumping out water vapor is insufficient or when there is a large amount of cooling water, the condensed water may be carried out and enter the air duct 240 after the air duct 210 adsorbs water vapor, and further enter the negative pressure fan 220, damaging the internal components of the negative pressure fan 220. Through the emergency discharge device 400, a large amount of water vapor and the generated condensed water can be quickly discharged.

[0057] In some embodiments, a steam separator can also be provided at the negative pressure fan 220 to separate water vapor, or a condenser can be provided to convert water vapor into condensed water to prevent the water vapor from corroding the negative pressure fan 220.

[0058] Furthermore, a sensor and a remote control device can also be provided near the crystallization wheel 300 to automatically adjust the operating speed of the negative pressure fan 220 according to the amount of water vapor generated, reduce the loss of the negative pressure fan 220, lower the operating cost, and enable the staff to monitor the operating state of the water vapor discharge device.

[0059] Figure 2 It is a schematic structural diagram of the crystallization wheel arranged in the crystallization wheel placement cavity provided by the embodiment of the present application. As Figure 2 shown, a maintenance opening 112 is also provided on the cover plate 110. The maintenance opening 112 is connected to the crystallization wheel fixing port 111 and communicates with the crystallization wheel placement cavity 100. A maintenance plate 113 that can be detachably installed is provided on the maintenance opening 112.

[0060] The crystal wheel fixing port 111 and the maintenance port 112 are both provided on the cover plate 110. The difference is that in order to ensure the structural stability of the crystal wheel 300, the crystal wheel fixing port 111 is usually provided in the middle position of the cover plate 110 to ensure that the crystal wheel 300 can be firmly installed in the crystal wheel placement cavity 100 through the crystal wheel fixing port 111. The maintenance port 112 is generally provided at a position on one side of the cover plate 110 close to the crystal wheel 300, that is, connected to the crystal wheel fixing port 111, facilitating the staff to enter the crystal wheel placement cavity 100 through the maintenance port 112 for inspection and maintenance.

[0061] When the crystal wheel 300 is not in the crystallization state, since the maintenance port 112 is connected to the crystal wheel fixing port 111, the staff can enter the interior of the crystal wheel placement cavity 100 through the maintenance port 112 to repair the crystal wheel 300 and determine whether the fixing state of the crystal wheel 300 is stable through the crystal wheel fixing port 111. Further, the maintenance plate 113 is detachably installed on the maintenance port 112. When maintenance is required, the maintenance plate 113 can be opened to facilitate inspection and cleaning of the crystal wheel 300. When the crystal wheel is crystallizing, the maintenance plate 113 is closed to prevent foreign objects from entering the interior of the crystal wheel 300 and ensure that the liquid metal can smoothly flow through the crystal wheel 300 and solidify into a solid state.

[0062] When the crystal wheel 300 is arranged in the crystal wheel placement cavity 100, in this embodiment, a rotating shaft 310 is provided in the crystal wheel placement cavity 100, and the crystal wheel 300 is arranged in the crystal wheel placement cavity 100 by being installed on the rotating shaft 310. An arc-shaped cover plate 114 is also provided on the maintenance plate 113. Among them, when the maintenance plate 113 covers the maintenance port 112, the arc-shaped cover plate 114 covers the rotating shaft 310.

[0063] The crystal wheel 300 is a key device of the casting system, and the rotating shaft 310 is an important component to ensure the normal operation of the crystal wheel 300. The rotating shaft 310 is usually located at the geometric center of the crystal wheel 300 to ensure the balance and stability of the crystal wheel 300. Therefore, an arc-shaped cover plate 114 is provided on the maintenance plate 113. The arc-shaped cover plate 114 is disposed opposite to the rotating shaft 310 and is slightly larger than the rotating shaft 310. Thus, when the maintenance plate 113 covers the maintenance port 112, the arc-shaped cover plate 114 serves as a protective cover and will synchronously cover the rotating shaft 310, which can protect the rotating shaft 310 from being affected by dust and other foreign objects, extend its service life, and also prevent the staff from contacting the rotating parts.

[0064] In this embodiment, the cover plate 1101 at the first port wall and the cover plate 1102 at the second port wall on the crystal wheel fixing port 111 are both inclined towards the interior of the crystal wheel placement cavity 100.

[0065] Among them, the cover plate 1101 at the first port wall and the cover plate 1102 at the second port wall are respectively located on both sides of the crystallization wheel 300. Tilting them both towards the inside of the crystallization wheel placement cavity 100 can facilitate the water vapor generated at the crystallization wheel 300 to enter the air duct 210 in the crystallization wheel placement cavity 100 through the cover plate 1101 at the first port wall and the cover plate 1102 at the second port wall, preventing the accumulation of water vapor and cooling water on the cover plate 110 and affecting casting.

[0066] Figure 3 It is a schematic structural diagram of the air duct provided by the embodiment of the present application. As Figure 3 shown, in this embodiment, a connection port groove 212 is provided on the air duct 210. A telescopic hose connection port 213 is opened at the bottom of the connection port groove 212. The telescopic hose 230 is installed at the telescopic hose connection port 213. Among them, a magnetic adsorption layer 214 is provided on the outer groove wall at the notch of the connection port groove 212.

[0067] Through the connection port groove 212, when it is not necessary to discharge water vapor, the telescopic hose 230 can be stored inside the air duct 210, and when it is necessary to discharge water vapor, the telescopic hose 230 can be installed at the telescopic hose connection port 213 to conduct gas flow between the air ducts 210.

[0068] For occasions where the space of the air duct 210 needs to be controlled, such as when the crystallization wheel placement cavity 100 is small due to the small crystallization wheel 300, the air ducts 210 can be adsorbed together in sequence through the magnetic adsorption layer 214 provided on the outer groove wall at the notch of the connection port groove 212, and the telescopic hose 230 can be received into the air duct 210, saving space on the premise of not affecting the water vapor collection effect.

[0069] The water vapor drainage device of the casting system provided by the embodiment of the present application includes a crystallization wheel placement cavity 100 and a collection member 200. On the one hand, the cover plate 110 at the top of the crystallization wheel placement cavity 100 can prevent water vapor from entering the inside of the crystallization wheel placement cavity 100 and prevent the surface of the crystallization wheel 300 from being corroded or damaged. On the other hand, through the air duct 210 connected to the negative pressure fan 220 and the air duct 240 connected to the air duct 210, the water vapor generated at the crystallization wheel 300 can be inhaled into the air duct 210 through the air outlet 211 and flow to the negative pressure fan 220 until it is discharged. Thus, the problem that the diffusion of water vapor cannot be effectively controlled in the casting system can be solved. By connecting the air ducts 210 in sequence through the telescopic hose 230, the air duct 210 can move in the crystallization wheel placement cavity 100, which is beneficial to improving the flexibility of the air duct 210 and the efficiency of collecting water vapor, preventing water vapor from invading the interior of the product, and thus beneficial to improving the quality of the product.
