Description

Technical Field

[0001] This application relates to the field of cooling device technology, and in particular to a rapid cooling device for inoculants. Background Technology

[0002] The inoculant is a substance that promotes graphitization, reduces the tendency for white iron formation, improves graphite morphology and distribution, increases the number of eutectic clusters, and refines the matrix structure. It has good effects within a short time after inoculation treatment (approximately 5-8 minutes). It is mainly suitable for general conditions or short-term inoculation in various situations.

[0003] The inoculant melt is a liquid material formed after being heated to a high temperature. At this point, the inoculant melt is placed into a mold to form a specific shape, depending on the application. After cooling in the mold, it will solidify. Water cooling is often used during the cooling process. This cooling method requires a large amount of water, which needs to be constantly flowing and replaced. The entire molding and cooling process not only consumes a large amount of water, but also requires the use of fans to cool the circulating water before putting it back into use. This water cooling method not only consumes a lot of electricity, but also does not improve the cooling effect of the water, and the operating cost of the equipment in the entire production process cannot be reduced.

The rapid cooling box is cylindrical in shape. The diameter of the vertical pipe is smaller than the diameter of the rapid cooling box.

[0008] Preferably, the rapid cooling box is provided with a conical box inside. The upper port of the conical box is connected to the connection between the vertical pipe and the rapid cooling box. The small port of the conical box faces the inside of the rapid cooling box. A long pipe is welded to the side wall of the conical box. The long pipe communicates with the conical box and is evenly arranged along the outer wall of the conical box.

[0009] Preferably, a protrusion is welded to the inner side wall of the rapid cooling box. The protrusion is evenly distributed around the circumference of the rapid cooling box. The protrusion is cylindrical in shape. The outer end of the protrusion faces the conical box. A connecting rod is provided on the conical box. The connecting rod is coaxial with the conical box. An explosion-proof motor is connected to the lower end of the connecting rod.

[0010] Preferably, a fixing frame is provided on the bottom and side wall of the water collection tank. The fixing frame is arranged in a circular shape, and a first top rod is slidably connected to the fixing frame provided on the side wall of the water collection tank.

[0011] Preferably, the output end of the first push rod is triangular in shape, and a sliding rod is attached to the inclined surface of the first push rod. The sliding rod is rectangular in shape and is slidably connected to the side wall of the rapid cooling box.

[0012] Preferably, a shovel head is provided on the slide rod inside the rapid cooling box, and the shovel head is attached to the aluminum plate. The slide rod outside the rapid cooling box is T-shaped, and a return spring is sleeved on the external slide rod.

[0013] Preferably, a second push rod is slidably connected to the fixing frame at the bottom of the water collection tank. The second push rod has the same shape as the first push rod, and the inclined surface of the second push rod overlaps the input end of the first push rod.

[0014] Preferably, a top head is attached to the input end of the second top rod, the top head is welded to the connecting rod, the connecting rod passes through the water collection tank and is located outside the water collection tank, and the explosion-proof motor on the connecting rod is fixedly connected to the lower part of the cooling tank.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This is a rapid cooling device for inoculants. The inoculant mold receives the inoculant melt in front of the furnace and waits for it to cool to below 800°C (when the surface of the inoculant is visually solidified). Then, a bridge crane is used to lift the mold into a water-cooling tank for cooling. After rapid cooling, the bridge crane is used to lift the mold to the inoculant preparation area, where the inoculant is poured out. A water-cooling tank is installed on the cooling box, and a certain volume of water can be pre-filled in the water-cooling tank. The water in the water-cooling tank can quickly cool the high-temperature inoculant. After the cooled high-temperature inoculant and the mold enter the water-cooling tank, the equipment can be started. The water in the water-cooling tank can then enter the conical seat and finally fall into the conical box through the vertical pipe. The water entering the vertical pipe can first be cooled by the heat sink, thus initially dissipating the heat absorbed by the water. As the water falls, it will collect in the conical box. Due to the restriction of the conical box, the water in the water-cooling tank drains slowly. With the water sprayed from the nozzle, the liquid level in the water-cooling tank can be kept stable at a certain height, thus ensuring the cooling of the high-temperature inoculant and the mold.

[0017] When the equipment is running, the water absorbs heat and falls into the conical box. The explosion-proof motor drives the conical box through a connecting rod, causing it to rotate. Long pipes are welded to the side walls of the conical box. As the box rotates, it splashes water onto the side walls of the rapid cooling chamber. The water impacts the protrusions on the side walls, breaking it up and allowing for better heat dissipation. The scattered water drips down the side walls and eventually lands on an aluminum plate at the bottom of the chamber. Cooling fins are installed on the outside of these fins, with the cold end temperature reaching between -20 and -10 degrees Celsius. This allows the surface of the aluminum plate inside the water-cooled chamber to cool. As ice and water gradually accumulate, the water cools down rapidly, achieving efficient heat dissipation. The cooled water continues to drain and eventually collects in a water collection tank. This tank is located near the cooling coils, thus cooling them to ensure their operation. The cooling water in the collection tank is then pumped through a circulating pump and sprayed into the water-cooling tank through nozzles. This maintains the water in the water-cooling tank at a low temperature, achieving rapid cooling of the high-temperature inoculant. Compared to traditional water-cooling equipment, this system uses less water. The water circulation process effectively dissipates heat before reuse, and the overall cost is controllable, enabling low-cost production.

[0018] This inoculant rapid cooling device has an explosion-proof motor installed on the cooling box. The connecting rod of the explosion-proof motor is equipped with a top head. A second top rod is located in the rotation direction of the top head. When the second top rod is pushed by the top head, it will move outward. A first top rod is located in the movement direction of the second top rod. The first top rod will be pushed upward by the second top rod. The first top rod will push a sliding rod, which will drive the shovel head to move. The shovel head can scrape off the ice formed on the surface of the aluminum plate, thereby mixing it with water and draining it away, thus achieving efficient heat dissipation of the water.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides a rapid cooling device for an inoculant, comprising a fan 27, a mold 4, a cooling box 1, an explosion-proof motor 11, and a circulating pump 2. The circulating pump 2 is installed on the side wall of the cooling box 1. The output end of the circulating pump 2 is connected to a round pipe 5, which is located on a water-cooling tank 3. The output end of the water-cooling tank 3 is located inside the cooling box 1. A rapid cooling box 9 is provided inside the cooling box 1. A water collection tank 10 is connected to the lower part of the rapid cooling box 9. The input end of the circulating pump 2 is connected to the side wall of the water collection tank 10. An aluminum plate 25 is provided at the bottom of the rapid cooling box 9. A cooling plate 17 is connected to the outside of the aluminum plate 25. A drain 26 is provided at the position where the aluminum plate 25 communicates with the water collection tank 10. After water is injected into the water-cooling tank 3, the inoculant melt can be cooled. The water in the cooling process will be discharged downwards and collected in the conical box 20. The water will then be thrown into the rapid cooling box 9 and finally fall onto the aluminum plate 25 of the rapid cooling box 9. The water in contact with the aluminum plate 25 will form a layer of ice. The water that continues to be discharged downwards can absorb heat and dissipate heat quickly. The cooled water continues to be discharged into the water collection tank 10 and finally transported to the water-cooling tank 3 by the circulating pump 2, thereby achieving efficient cooling of the inoculant melt and reducing the operating cost of the equipment during the cooling process.

[0030] Cooled water is stored in the water collection tank 10 and transported by the circulating pump 2 through the circular pipe 5 to the top of the cooling device. It is then sprayed onto the inoculant mold through the nozzle 6 for forced cooling, and the heated water flows into the water cooling tank 3. It undergoes initial cooling through the conical seat 7, vertical pipe 8, and heat sink 12. It then flows into the conical box 20, where, as the conical box 20 rotates, the water is splashed onto the inner wall of the rapid cooling box 9 through the long pipe 21 and further cooled by the protrusions 22. The water then falls onto the aluminum plate 25 and forms thin ice under the action of the cooling fins 17 installed below the aluminum plate 25. As the water gradually flows down, it mixes with the previously formed thin ice for further cooling and flows into the water collection tank 10 through the drain 26, entering the next cycle.

[0031] Nozzles 6 are welded to the side wall of the circular tube 5. The nozzles 6 are arranged in an L-shape, with their output ports facing the inside of the water-cooling tank 3. The nozzles 6 are evenly arranged around the circular tube 5. A conical seat 7 is welded to the lower part of the water-cooling tank 3, with its small port facing the inside of the cooling box 1. The cooled water can be quickly injected into the water-cooling tank 3 through the nozzles 6, thus ensuring that the water volume in the water-cooling tank 3 does not change too much.

[0032] A vertical pipe 8 is welded to the small end of the conical seat 7. A rapid cooling box 9 is connected to the lower end of the vertical pipe 8. The rapid cooling box 9 is cylindrical in shape. The diameter of the vertical pipe 8 is smaller than the diameter of the rapid cooling box 9. A heat sink 12 is provided on the vertical pipe 8 between the rapid cooling box 9 and the conical seat 7. The heat sink 12 is arranged along the length of the vertical pipe 8. The vertical pipe 8 can guide the flow of water, and the heat sink 12 can perform preliminary heat dissipation of the water, thereby improving the heat dissipation efficiency.

[0033] In practice, a water-cooling tank 3 is installed on the cooling box 1. A certain volume of water can be pre-filled in the water-cooling tank 3 to rapidly cool the inoculant inside the mold. After the inoculant mold receives the inoculant melt in front of the furnace and cools to a suitable temperature, a bridge crane is used to lift the mold into the water-cooling tank 3, and then the equipment can be started for rapid cooling. The water in the water-cooling tank 3 can then enter the conical seat 7 and finally fall into the conical box 20 through the vertical pipe 8. The water entering the vertical pipe 8 is first cooled by the heat sink 12, thus initially dissipating heat. As the water falls, it collects in the conical box 20. Due to the restriction of the conical box 20, the water in the water-cooling tank 3 drains slowly. The water sprayed from nozzle 6 keeps the liquid level in the water-cooling tank 3 stable at a certain height, thus ensuring the cooling of the high-temperature inoculant. The explosion-proof motor 11 drives the conical box 20 via connecting rod 19, causing it to rotate. A long pipe 21 is welded to the side wall of the conical box 20. When the conical box 20 rotates, it splashes water from inside onto the side wall of the rapid cooling box 9. The water impacts the protrusions 22 on the side wall of the rapid cooling box 9, thus breaking up the water. The scattered water then dissipates heat more effectively. The water drips down the side wall of the rapid cooling box 9, eventually landing on the aluminum plate 25 at the bottom. A cooling fin 17 is installed on the outside of the aluminum plate 25. The cold end temperature of the cooling fin 17 reaches between -20 and -10 degrees Celsius, causing ice to form on the surface of the aluminum plate 25 inside the water-cooling box. As the water gradually collects, it cools rapidly, achieving efficient heat dissipation. The cooled water continues to drain downwards, eventually collecting in the water collection tank 10. The water collection tank 10 is close to the cooling fin 17, thus further cooling the cooling fin 17 to ensure... The operation of the cooling plate 17 can be achieved by installing a fan 27 on the cooling box 1 at the location of the cooling plate 17 to force heat dissipation of the cooling plate 17. The cooling water in the water collection tank 10 can be transported by the circulating pump 2. The nozzle 6 sprays water onto the inoculant mold for forced cooling and flows into the water cooling tank 3, so that the water in the tank can maintain a low temperature, thereby achieving rapid cooling of the inoculant. The water volume of the entire equipment is smaller than that of traditional water cooling equipment. The water can be effectively cooled and reused during the water circulation process. The cost of the entire equipment is controllable, and low-cost production can be achieved.

[0034] The rapid cooling box 9 contains a conical box 20. The upper port of the conical box 20 is connected to the connection between the vertical pipe 8 and the rapid cooling box 9. The smaller port of the conical box 20 faces inward. A long pipe 21 is welded to the side wall of the conical box 20, communicating with the conical box 20. The long pipe 21 is evenly distributed along the outer wall of the conical box 20. The conical box 20 can hold the water, preventing the water from flowing down too quickly and controlling the water volume.

[0035] The internal sidewall of the rapid cooling box 9 is welded with protrusions 22, which are evenly distributed around the circumference of the box. The protrusions 22 are cylindrical in shape, with their outer ends facing the conical box 20. A connecting rod 19 is mounted on the conical box 20, coaxial with it. An explosion-proof motor 11 is connected to the lower end of the connecting rod 19. By using the protrusions 22, water thrown towards them is more dispersed, breaking down into particles. This causes the water to drip as it flows towards the aluminum plate 25, rapidly absorbing heat and thus quickly dissipating it.

[0036] The bottom and side walls of the water collection tank 10 are equipped with fixing frames 24, which are arranged in a circular shape. A first push rod 16 is slidably connected to the fixing frame 24 on the side wall of the water collection tank 10. The fixing frame 24 can restrict the first push rod 16 and the second push rod 23, allowing the first push rod 16 and the second push rod 23 to move within the fixing frame 24.

[0037] The output end of the first push rod 16 is triangular in shape. A sliding rod 14 is attached to the inclined surface of the first push rod 16. The sliding rod 14 is rectangular in shape and is slidably connected to the side wall of the rapid cooling box 9. The sliding rod 14 drives the shovel head 13, which can move horizontally with the sliding rod 14. Through the connection between the sliding rod 14 and the first push rod 16, the first push rod 16 can push the sliding rod 14, allowing the sliding rod 14 to move.

[0038] A scraper head 13 is installed on the slide rod 14 inside the rapid cooling box 9. The scraper head 13 rests on the aluminum plate 25. The slide rod 14 outside the rapid cooling box 9 is T-shaped, and a return spring 15 is sleeved on the outer slide rod 14. The scraper head 13 can move along the aluminum plate 25 to scrape off the ice layer formed on the aluminum plate 25, thereby mixing with the water and ultimately cooling the water.

[0039] A second push rod 23 is slidably connected to the fixing bracket 24 at the bottom of the water collection tank 10. The second push rod 23 has the same shape as the first push rod 16, and the inclined surface of the second push rod 23 overlaps with the input end of the first push rod 16. The second push rod 23 can push the first push rod 16 during movement, and the first push rod 16 can move upward.

[0040] The input end of the second push rod 23 is connected to a push head 18, which is welded to a connecting rod 19. The connecting rod 19 passes through the water collection tank 10 and is located outside the water collection tank 10. The explosion-proof motor 11 on the connecting rod 19 is fixedly connected to the lower part of the cooling tank 1. The connecting rod 19 can be rotated by the explosion-proof motor 11, which in turn drives the push head 18 to rotate, thereby pushing the inclined surface of the second push rod 23 near the push head 18. The second push rod 23 can then perform horizontal radial movement.

[0041] In practice, an explosion-proof motor 11 is installed on the cooling box 1. A top head 18 is provided on the connecting rod 19 of the explosion-proof motor 11. A second top rod 23 is provided in the rotation direction of the top head 18. After being pushed by the top head 18, the second top rod 23 will move outward. A first top rod 16 is provided in the movement direction of the second top rod 23. The first top rod 16 will be pushed upward by the second top rod 23. The first top rod 16 will push the sliding rod 14. The sliding rod 14 will drive the shovel head 13 to move. The shovel head 13 can scrape off the ice formed on the surface of the aluminum plate 25, and then drain it away along with the water, thereby achieving efficient cooling of the water.

[0042] The working principle of this invention is as follows: A water-cooling tank 3 is installed on the cooling tank 1. A certain volume of cooled water can be pre-filled into the water-cooling tank 3. The water in the water-cooling tank 3 can provide rapid cooling for the inoculant. After the cooled inoculant and its mold enter the water-cooling tank 3, the equipment can be started. After the inoculant mold receives the inoculant melt in front of the furnace, it is cooled to a suitable temperature. Then, the bridge crane is used to lift the mold into the water-cooling tank 3, and the equipment can be started for rapid cooling. The water in the water-cooling tank 3 can then enter the conical seat 7 and finally fall into the conical box 20 through the vertical pipe 8. The water entering the vertical pipe 8 can first be cooled by the heat sink 12, thus initially dissipating the heat absorbed by the water. As the water falls, it will collect in the conical box 20. Due to the restriction of the conical box 20, the water in the water-cooling tank 3 flows down slowly. With the water sprayed by the nozzle 6, the liquid level in the water-cooling tank 3 can be kept stable at a certain height, thereby ensuring the cooling of the high-temperature inoculant. For cooling, the explosion-proof motor 11 drives the conical box 20 via the connecting rod 19, causing the conical box 20 to rotate. A long pipe 21 is welded to the side wall of the conical box 20. When the conical box 20 rotates, it splashes water from inside onto the side wall of the rapid cooling box 9. The water impacts the protrusions 22 on the side wall of the rapid cooling box 9, thus breaking up the water. The scattered water then dissipates heat more effectively. The scattered water drips down the side wall of the rapid cooling box 9, eventually landing on the aluminum plate 25 at the bottom of the rapid cooling box 9. A cooling fin 17 is installed on the outside of the aluminum plate 25. The cold end temperature of the cooling fin 17 reaches between -20 and -10 degrees Celsius. Inside the water-cooled box... The aluminum plate 25 can freeze on its surface, and as the water gradually collects, it can be cooled quickly, achieving efficient heat dissipation. The cooled water continues to drain and eventually collects in the water collection tank 10. The water collection tank 10 is close to the cooling chip 17, thus cooling the cooling chip 17 to ensure its operation. The cooling water in the water collection tank 10 can be transported by the circulating pump 2. The nozzle 6 sprays water onto the inoculant mold for forced cooling and flows into the water cooling tank 3, keeping the water in the tank at a low temperature, thereby achieving rapid cooling of the inoculant. The entire equipment uses less water than traditional water cooling equipment, and the water circulation process can effectively dissipate heat. The equipment is reusable, and the overall cost is controllable, enabling low-cost production. The cooling box 1 is equipped with an explosion-proof motor 11. The connecting rod 19 of the explosion-proof motor 11 is equipped with a top head 18. A second top rod 23 is provided in the rotation direction of the top head 18. After being pushed by the top head 18, the second top rod 23 will move outward. A first top rod 16 is provided in the movement direction of the second top rod 23. The first top rod 16 will be pushed upward by the second top rod 23. The first top rod 16 will push the sliding rod 14, which will drive the shovel head 13 to move. The shovel head 13 can scrape off the ice formed on the surface of the aluminum plate 25, thereby mixing it with water and draining it away, thus achieving efficient cooling of the water.
