Description

Technical Field

[0001] This utility model relates to the field of induction furnace technology, specifically a vacuum induction directional zone furnace. Background Technology

[0002] A furnace is a commonly used piece of equipment in metal smelting. An induction furnace, also known as an induction electric furnace, is a type of furnace. Most existing smelting furnaces use mobile dust hoods. According to a search, patent application number CN202322889403.3 discloses a medium-frequency induction electric furnace with good dust prevention effect. When the flue gas generated by the furnace is working rises, the exhaust fan is started, and a negative pressure is generated at the flared mouth through the curved pipe, flexible hose and metal pipe, which can draw the flue gas into the flared mouth.

[0003] The process of the above-mentioned device drawing in air and smoke will cause the air around the furnace to flow faster, which will speed up the cooling of the furnace. The opening of the furnace will also accelerate the diffusion of heat from the furnace to the surrounding area. In subsequent heating, the induction coil will need to provide more heat. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vacuum induction directional zone furnace, which solves the technical problem that existing induction furnaces cannot effectively block dust from approaching the furnace by utilizing air pressure differences, and can clean away the dust around the furnace with a slow airflow speed, thereby slowing down the rate at which heat diffuses to the surroundings when the furnace is opened.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vacuum induction directional zone furnace, comprising a furnace body, wherein a dustproof component is installed on the top of the furnace body;

[0006] The dustproof component includes a longitudinal frame fixedly connected to the furnace body. Ventilation holes are provided on both sides of the longitudinal frame. A water storage tank is fixedly connected to the bottom inner side of the longitudinal frame. A heat dissipation component is installed on the top of the water storage tank. A slowing component is installed on the side of the longitudinal frame closest to the furnace body.

[0007] Furthermore, the heat dissipation assembly includes an outer tube fixedly connected to the water storage tank, and the interior of the outer tube is provided with a hollow metal column that extends movably to the outside of it. An elastic rope is fixedly connected between the top of the hollow metal column and the longitudinal frame.

[0008] Furthermore, the deceleration component includes a mesh and a clamp, with the mesh fixed to the longitudinal frame via the clamp.

[0009] Furthermore, a circular hole is provided on one side of the clamping plate, and a threaded rod that can move through the circular hole is provided on one side of the longitudinal frame, with a nut installed at the end of the threaded rod away from the longitudinal frame.

[0010] Furthermore, a longitudinal plate is fixedly connected to the side of the longitudinal frame near the deceleration component, and a horizontal column is rotatably connected to the side of the longitudinal plate near the deceleration component.

[0011] Furthermore, one side of the water storage tank is connected to an external pipe extending to the outside of the longitudinal frame, and the external pipe is connected to the water cooling circulation pipe of the furnace body.

[0012] Furthermore, both sides of the hollow metal column are rotatably connected to arc-shaped metal plates, and the inner wall of the longitudinal frame is fixedly connected to a magnet block corresponding to the arc-shaped metal plate.

[0013] By employing the above technical solution, this utility model provides a vacuum induction directional zone furnace, which has at least the following beneficial effects:

[0014] 1. This utility model, through the dustproof component, can filter the air using a longitudinal frame with vents, and then heat the filtered air and slowly deliver it to the furnace body, increasing the air pressure at the furnace body. The air pressure difference effectively blocks dust from approaching the furnace, while the slow airflow speed cleans up the dust around the furnace, thus slowing down the rate at which heat diffuses to the surroundings when the furnace is opened.

[0015] 2. The present invention, through the heat dissipation component, can increase the contact area of ​​the outer tube, the hollow metal column, and the arc-shaped metal plate when the temperature of the heat dissipation component is low, thereby accelerating the transfer of heat to the outer tube, the hollow metal column, and the arc-shaped metal plate. When the temperature of the heat dissipation component rises, it increases the contact area between the outer tube, the hollow metal column, and the arc-shaped metal plate and the air, thereby increasing the speed at which heat is transferred from the heat dissipation component to the surrounding air, and maximizing the heating effect on the air.

[0016] 3. This utility model, through the setting of a slowing component, can slow down the speed of airflow towards the furnace body, while filtering dust in the airflow towards the furnace body.

[0017] 4. By using the external pipe, this utility model can utilize the heat absorbed by the furnace's water cooling system to heat the air inside the longitudinal frame, thereby reducing the power consumption required to heat the air inside the longitudinal frame. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] To increase the air pressure at the furnace location and use the pressure difference to prevent dust from approaching the furnace, please refer to... Figures 1-5 This embodiment proposes a vacuum induction directional zone furnace, including a furnace body 1. A dustproof component 2 is installed on the top of the furnace body 1. The dustproof component 2 includes a longitudinal frame 21 fixedly connected to the furnace body 1. Ventilation holes are opened on both sides of the longitudinal frame 21. A water storage tank 22 is fixedly connected to the bottom inner side of the longitudinal frame 21. A heat dissipation component 23 is installed on the top of the water storage tank 22. A deceleration component 24 is installed on the side of the longitudinal frame 21 near the furnace body 1.

[0028] In use, hot water is introduced into the water tank 22. The heat from the hot water is transferred to the air inside the longitudinal frame 21 through the heat dissipation component 23, heating the air inside the longitudinal frame 21. As the air temperature rises, its volume expands and diffuses to both sides through the vents in the longitudinal frame 21. When air from outside the longitudinal frame 21 replenishes the interior, dust is blocked by the vents, creating a filtering effect. The hot air moving towards one side of the furnace body 1 is slowed down by the deceleration component 24 and moves towards the furnace body 1 at a slower speed. This slow delivery of hot air to the furnace body 1 increases the air volume at that location and... The air temperature at the furnace body 1 is increased, causing the air at the furnace body 1 to expand in volume due to heating and increase in air pressure. This creates an air pressure difference between the furnace body 1 and its surroundings. The air at the furnace body 1 continuously flows to the surroundings, while the surrounding air cannot flow to the furnace body 1. The air can be filtered using a longitudinal frame 21 with vents. The filtered air is then heated and slowly delivered to the furnace body 1, increasing the air pressure at the furnace body 1. The air pressure difference effectively prevents dust from approaching the furnace, while the slow airflow removes dust from around the furnace, slowing down the rate at which heat diffuses to the surroundings when the furnace is opened.

[0029] To improve the heating effect on the air and thus accelerate the rate of increase in air pressure at location 1 of the furnace body, refer to... Figure 4 and Figure 5 The heat dissipation component 23 includes an outer tube 231 fixedly connected to the water tank 22. The outer tube 231 has a hollow metal column 232 with one end extending movably to the outside. An elastic rope 233 is fixedly connected between the top of the hollow metal column 232 and the longitudinal frame 21. An arc-shaped metal plate 9 is rotatably connected to both sides of the hollow metal column 232. A magnet block 10 corresponding to the arc-shaped metal plate 9 is fixedly connected to the inner wall of the longitudinal frame 21.

[0030] In use, the curved metal plate 9 falls vertically due to its own gravity, causing it to adhere tightly to the surface of the hollow metal column 232. At this point, the contact area between the curved metal plate 9 and the hollow metal column 232 is at its maximum, allowing heat from the hollow metal column 232 to be transferred to the curved metal plate 9 most quickly. The upward pull of the elastic rope 233 on the hollow metal column 232 offsets some of the weight that the hollow metal column 232 needs to overcome when rising. Initially, the hollow metal column 232 is in its lowest position, and the distance between the curved metal plates 9 on both sides and the magnet 10 is relatively far. The magnet 10 cannot drive the curved metal plates 9 to rotate away from the hollow metal column 232. As the heat from the hot water in the water tank 22 is gradually transferred to the outer pipe 231 and the hollow metal column 232, the curved metal plate 9 is also heated, and the heat inside the outer pipe 231... As the temperature of the air gradually increases, the air volume inside the outer tube 231 expands, pushing the hollow metal column 232 to rise gradually. This causes the arc-shaped metal plate 9 to rise and gradually approach the magnet block 10. The arc-shaped metal plate 9, which was originally attached to the hollow metal column 232, is rotated away from the hollow metal column 232 by the magnet block 10. This increases the contact area between the outer tube 231, the hollow metal column 232, and the arc-shaped metal plate 9 when the temperature of the heat dissipation component 23 is low, accelerating the transfer of heat to the outer tube 231, the hollow metal column 232, and the arc-shaped metal plate 9. When the temperature of the heat dissipation component 23 rises, it increases the contact area between the outer tube 231, the hollow metal column 232, and the arc-shaped metal plate 9 and the air, increasing the speed at which heat is transferred from the heat dissipation component 23 to the surrounding air, thus maximizing the heating effect on the air.

[0031] To slow down the airflow and thus reduce the rate at which internal heat is blown away by the airflow when the furnace body 1 is opened, refer to Figure 2 The deceleration component 24 includes a mesh 241 and a clamping plate 242. The mesh 241 is fixed to the longitudinal frame 21 by the clamping plate 242. A round hole is provided on one side of the clamping plate 242. A threaded rod 4 that can move through the round hole is provided on one side of the longitudinal frame 21. A nut 5 is installed at the end of the threaded rod 4 away from the longitudinal frame 21. A longitudinal plate 6 is fixedly connected to the side of the longitudinal frame 21 near the deceleration component 24. A horizontal column 7 is rotatably connected to the side of the longitudinal plate 6 near the deceleration component 24.

[0032] In use, the mesh 241 is attached to the side of the longitudinal frame 21 near the furnace body 1. Then, the round hole of the clamping plate 242 is passed through the threaded rod 4. Next, the nut 5 is put on the threaded rod 4 and rotated so that the clamping plate 242 clamps the upper part of the mesh 241 on the longitudinal frame 21. Then, the lower part of the mesh 241 is passed between the horizontal column 7 and the longitudinal frame 21 so that both the upper and lower ends of the mesh 241 are limited on the longitudinal frame 21. When the heated air inside the longitudinal frame 21 moves towards the furnace body 1, the air is slowed down and filtered by the mesh 241. The slowed-down air blows away the heat inside the furnace body 1 more slowly, which can slow down the speed of the air flowing towards the furnace body 1 and filter the dust in the air flowing towards the furnace body 1.

[0033] In order to improve the thermal utilization efficiency of the furnace, refer to Figure 4 One side of the water storage tank 22 is connected to an external pipe 8 extending to the outside of the longitudinal frame 21. The external pipe 8 is connected to the water cooling circulation pipe of the furnace body 1. When in use, the water cooling circulation pipe of the furnace body 1 cools the furnace body 1 as it passes through the interior of the furnace body 1. The water inside the water cooling circulation pipe absorbs heat and its temperature rises. Then, the heated water is transported to the water storage tank 22, so that the heat of the water in the water storage tank 22 heats the air inside the water storage tank 22 and diffuses it towards the furnace body 1. The heat absorbed by the furnace's water cooling system can be used to heat the air inside the longitudinal frame 21, reducing the power consumption required to heat the air inside the longitudinal frame 21.
