A thin plate 15, a rubber plate 16 and two baffles 17 are arranged inside the guide pipe 14. The heat exchange exhaust assembly uses the heat inside the high-temperature smelting furnace 5 for cleaning and preheating the alloy material. A telescopic pipe 25 is rotatably connected between the transmission pipe 26 and the metal pipe 7. A transmission assembly is arranged between the transmission pipe 26 and the metal pipe 7. The transmission assembly enables the metal pipe 7 to rotate inside the high-temperature smelting furnace 5. One end of the transmission pipe 26 is connected to a water supply assembly and an air extraction assembly. The water supply assembly and the air extraction assembly provide power for the transmission assembly. A lifting structure is arranged between the air supply assembly and the metal pipe 7. The air supply assembly provides power for the lifting structure to work during the process of circulating air inside the high-temperature smelting furnace 5.

[0040] Specifically,

[0041] The filter screen 8 is rotatably sleeved on the outside of the metal tube 7, and the bottom end of the metal tube 7 is rotatably connected to the collecting frame 10. The metal tube 7 can rotate inside the high-temperature smelting furnace 5. The collecting frame 10 is fixedly connected to the bottom of the filter screen 8, and the partition block 9 is fixedly connected to the bottom of the collecting frame 10. The filter screen 8, the collecting frame 10 and the partition block 9 constitute a movable plug, and the movable plug cooperates with the partition frame 6 to separate the top and bottom of the inner cavity of the high-temperature smelting furnace 5. After the alloy material enters the high-temperature smelting furnace 5 through the feed valve 4, it is cleaned and preheated at the top of the inner cavity of the high-temperature smelting furnace 5.

[0042] Finally, the movable plug moves up, and the alloy material falls to the bottom of the inner cavity of the high-temperature smelting furnace 5. The alloy material is subjected to high-temperature smelting processing at the bottom of the inner cavity of the high-temperature smelting furnace 5 to form liquid alloy material. The smelted liquid alloy material is discharged through the discharge valve 2, and the discharge valve 2 injects the liquid alloy material into the casting mold transported by the conveyor belt 3. The casting of the guide can be completed when the material in the casting mold solidifies.

[0043] After the previous batch of alloy materials is subjected to high-temperature smelting processing at the bottom of the inner cavity of the high-temperature smelting furnace 5 or the previous batch of alloy materials is processed and discharged, the second batch of alloy materials enters the high-temperature smelting furnace 5 through the feed valve 4 and falls onto the top of the movable plug and the partition frame 6.

[0044] Control water supply components work:

[0045] The water supply assembly includes a water supply elbow 27, a first three-way valve 28 and two water pumps 29, one of the water pumps 29 is fixedly installed at the normally closed end of the first three-way valve 28, and the other water pump 29 is fixedly installed at the normally open end of the first three-way valve 28. The water pump 29 installed at the normally open end of the first three-way valve 28 is in operation, and the working water pump 29 pumps water to the inside of the first three-way valve 28. The water supply elbow 27 is fixedly connected between the transmission pipe 26 and the first three-way valve 28, and water enters the inside of the transmission pipe 26 through the first three-way valve 28 and the water supply elbow 27. A telescopic pipe 25 is rotatably connected between the transmission pipe 26 and the metal pipe 7, and water enters the inside of the metal pipe 7 through the telescopic pipe 25.

[0046] The valve body 23 is fixedly connected to the top of the inner cavity of the metal tube 7. The valve body 23 that is not opened plays a role in blocking water. The I-shaped frame 22 is fixedly connected to the bottom of the inner cavity of the metal tube 7. The water pipe 24 is fixedly connected between the I-shaped frame 22 and the valve body 23. The top of the water pipe 24 passes through the valve body 23. Water can only enter the inside of the water pipe 24. The bottom end of the water pipe 24 passes through the I-shaped frame 22. The bottom end of the water pipe 24 is fixedly connected to the heat pipe 20. The top of the spiral groove 21 is set at the bottom of the inner cavity of the water pipe 24. Figure 5 shown.

[0047] The water pipe 24 guides water into the spiral groove 21. The junction box 19 is fixedly connected to the bottom of the heat pipe 20. The bottom of the spiral groove 21 is set at the bottom of the inner cavity of the junction box 19. Under the guidance of the spiral groove 21, the water enters the junction box 19 in a spiral descending motion.

[0048] A plurality of air guide grooves 11 are provided on the outside of the collecting frame 10, and a plurality of curved grooves 12 are provided on the bottom of the partition frame 6. Because the air guide grooves 11 are aligned with the curved grooves 12, the heat at the bottom of the inner cavity of the high-temperature smelting furnace 5 enters the air guide grooves 11 through the curved grooves 12, and the heat enters the inner cavity of the collecting frame 10 through the air guide grooves 11. The bottom of the metal pipe 7 is connected with the inner cavity of the collecting frame 10, so the heat finally enters the metal pipe 7 and the I-shaped frame 22. When water flows through the inside of the water pipe 24, it exchanges heat with the heat inside the metal pipe 7. The heat conducting pipe 20 is fixedly sleeved on the outside of the I-shaped frame 22. When water flows through the inside of the spiral groove 21, the flow distance is long, and heat is exchanged with the heat inside the I-shaped frame 22, so that the water entering the inside of the junction box 19 is heated into high-temperature water, and the heat generated when the alloy material is smelted at high temperature in the high-temperature smelting furnace 5 is reused, thereby improving the utilization efficiency of resources.

[0049] Multiple guide tubes 14 are fixedly connected to the outside of the junction box 19, and the hot water entering the junction box 19 is divided into multiple guide tubes 14. Multiple nozzles 13 are respectively fixedly connected to one end of the multiple guide tubes 14. The hot water is finally sprayed to the bottom of the filter 8 through the nozzles 13 to flush and heat the alloy material on the top of the filter 8. The alloy material is cleaned with hot water heated by the internal heat of the high-temperature smelting furnace 5, and the cleaning quality is improved by hot water flushing.

[0050] The filter screen 8 supports the alloy material, so that the sewage passes through the holes of the filter screen 8 and falls into the collection frame 10 .

[0051] When water flows into the nozzle 13, the water pushes the rubber plate 16, which is fixedly connected to the top of the thin plate 15, so that the rubber plate 16 drives the thin plate 15 to move toward the nozzle 13. A sewage pipe 18 is fixedly connected to the bottom of the guide tube 14, and the moving thin plate 15 blocks the sewage pipe 18, so that the water flow inside the guide tube 14 cannot flow out through the sewage pipe 18.

[0052] Two baffles 17 are respectively arranged on both sides of the thin plate 15, the baffles 17 are fixedly connected to the guide pipe 14, and the sewage pipe 18 is arranged between the two baffles 17. When one end of the thin plate 15 is against the baffle 17 close to the nozzle 13, the movement of the thin plate 15 is limited, and the thin plate 15 cannot move. The water pressure inside the guide pipe 14 increases, and finally the rubber plate 16 is deformed by the impact of the water flow. The water enters the nozzle 13 and is sprayed out by the nozzle 13.

[0053] After a period of time, the normally closed end of the first three-way valve 28 is controlled to open, and the water pump 29 installed at the normally closed end of the first three-way valve 28 starts to work. The water pump 29 pumps water to generate suction. The water pump 29 extracts water from the top of the collecting rack 10 through the pipeline composed of the first three-way valve 28, the water supply elbow 27, the transmission pipe 26, the telescopic pipe 25, the water pipe 24, the spiral groove 21, the junction box 19 and the guide pipe 14. At this time, the rubber sheet 16 drives the thin plate 15 to move toward the junction box 19 under the action of suction, so that the top of the sewage pipe 18 loses its obstruction.

[0054] When one end of the thin plate 15 abuts against the baffle 17 near the junction box 19, the thin plate 15 stops moving, and finally the rubber plate 16 is deformed, and the sewage enters the inside of the guide pipe 14 through the sewage pipe 18, preventing the sewage from entering the inside of the nozzle 13. The sewage is pumped out by the water pump 29 through the pipeline, completing the cleaning and preheating of the material. Through the arrangement of the thin plate 15, the rubber plate 16, the two baffles 17 and the sewage pipe 18, the water supply and pumping work can be carried out in the same pipeline, reducing the equipment cost investment.

[0055] The transmission assembly includes an impeller 30, a gear box 31, a long gear 32 and a driven gear 34. The impeller 30 is rotatably arranged inside the transmission pipe 26. When the water inside the transmission pipe 26 flows at a high speed, it will drive the impeller 30 to rotate. Through the arrangement of the thin plate 15, the rubber plate 16, the two baffles 17 and the sewage pipe 18, the water supply and pumping work of the water supply assembly must pass through the transmission pipe 26. The water supply assembly provides uninterrupted power for the transmission assembly. The long gear 32 is relatively long overall. When the metal pipe 7 drives the driven gear 34 to move up and down, the meshing relationship between the driven gear 34 and the long gear 32 will not be destroyed.

[0056] The bottom end of the impeller 30 is fixedly connected to the input end of the gear box 31. The rotating impeller 30 inputs a rotational force into the gear box 31. The rotational force changes direction and speed inside the gear box 31. The long gear 32 is fixedly connected to the output end of the gear box 31. After the direction and speed change, the rotational force is transmitted to the long gear 32 by the gear box 31, so that the long gear 32 rotates. A mounting rod 33 is rotatably connected between the long gear 32 and the transmission tube 26. The mounting rod 33 supports the top of the long gear 32 so that the two ends of the rotating long gear 32 are evenly stressed, ensuring the stability of the operation of the long gear 32.

[0057] The driven gear 34 meshes with the outside of the long gear 32, and the rotating long gear 32 drives the meshed driven gear 34 to rotate. The driven gear 34 is fixedly sleeved on the outside of the metal tube 7. The rotating driven gear 34 drives the metal tube 7 to rotate. The metal tube 7 drives the stirring frame 45 fixed on the outside to rotate. The rotating stirring frame 45 stirs and mixes the alloy material, and homogenizes the alloy material composed of multiple materials. The metal tube 7 drives the fixed multiple guide tubes 14 to rotate, and the guide tube 14 drives the nozzle 13 fixed at one end to rotate, so that the nozzle 13 sprays high-temperature water to the alloy material in a rotating state. The stirred alloy material repeatedly contacts with the high-temperature water, and the stirred alloy materials collide and rub against each other, further improving the cleaning and preheating effects.

[0058] During the process of pumping water and discharging sewage by the water supply component, the metal pipe 7 also rotates to drive the stirring rack 45 to stir the alloy material to ensure that the sewage falls to the top of the collection rack 10. A cleaning brush 46 is fixedly connected between the sewage pipe 18 and the nozzle 13. When the nozzle 13 rotates on the top of the collection rack 10, multiple cleaning brushes 46 clean and stir the top of the collection rack 10 to prevent impurities from settling and accumulating on the top of the collection rack 10.

[0059] The two water pumps 29 in the water supply assembly are controlled to work alternately, and the alloy material is cleaned and preheated for multiple times.

[0060] After the cleaning and preheating of the alloy material is completed, the water inside the transmission pipe 26 and the metal pipe 7 is evacuated. The exhaust assembly is controlled to work, and the exhaust assembly includes an air pump 39, a second three-way valve 40, a dehumidification device 41, a reflux pipe 42, an exhaust pipe 43 and a solenoid valve 44. The air inlet end of the air pump 39 is fixedly arranged on one side of the transmission pipe 26. The air pump 39 extracts the air inside the short pipeline composed of the telescopic pipe 25, the water pipe 24, the spiral groove 21, the junction box 19 and the guide pipe 14 through the transmission pipe 26, and extracts air from the bottom of the filter screen 8 through multiple nozzles 13 and the sewage pipe 18. At this time, the valve body 23 is open, and the high-temperature gas inside the high-temperature smelting furnace 5 enters the top of the inner cavity of the metal pipe 7 through the curved groove 12, the air guide groove 11, the I-shaped frame 22, and the open valve body 23, and finally enters the transmission pipe 26. Therefore, the air pump 39 extracts high-temperature and high-humidity gas.

[0061] The second three-way valve 40 is fixedly connected between the gas outlet of the air pump 39 and the dehumidification device 41. The high-temperature and high-humidity gas output by the air pump 39 enters the dehumidification device 41 through the second three-way valve 40. The high-temperature and high-humidity gas is dehumidified in the dehumidification device 41. The return pipe 42 is fixedly connected between the dehumidification device 41 and the high-temperature smelting furnace 5. The high-temperature gas after dehumidification enters the high-temperature smelting furnace 5 through the return pipe 42. The air pump 39 extracts the high-temperature and high-humidity gas from the high-temperature smelting furnace 5 and dehumidifies it. The dry gas after dehumidification is transported back to the high-temperature smelting furnace 5. In this process, high-speed gas flows in the transmission pipe 26, and the transmission assembly rotates the metal pipe 7. The metal pipe 7 drives a plurality of stirring racks 45 to stir the alloy material, so that the high-temperature dry gas contacts the alloy material to form high-temperature and high-humidity gas. The exhaust assembly, the transmission pipe 26, the metal pipe 7, the high-temperature smelting furnace 5 and other structures allow the high-temperature gas inside the high-temperature smelting furnace 5 to circulate to dry the alloy material. During the circulation process, power is provided to the transmission assembly, so that the metal pipe 7 drives the stirring frame 45 to stir the alloy material, thereby improving the drying quality.

[0062] The normally closed end of the second three-way valve 40 is fixedly connected to the exhaust pipe 43. After the exhaust component has worked for a period of time, the second three-way valve 40 is controlled to work, and the normally closed end of the second three-way valve 40 is opened. At this time, the exhaust gas of the air pump 39 enters the exhaust pipe 43 through the second three-way valve 40 and no longer returns to the high-temperature smelting furnace 5. The gas inside the high-temperature smelting furnace 5 is exhausted, and the inside of the high-temperature smelting furnace 5 is vacuumized.

[0063] The lifting structure includes a lifting frame 35, a diverter box 36, two pneumatic telescopic rods 37 and an air guide elbow 38. The diverter box 36 is fixedly connected to the top of the equipment housing 1, and the air guide elbow 38 is fixedly connected between the diverter box 36 and the exhaust pipe 43. The air pump 39 discharges gas into the exhaust pipe 43, and the gas enters the diverter box 36 through the exhaust pipe 43 and the air guide elbow 38, so that the air pressure inside the diverter box 36 increases. The pneumatic telescopic rod 37 is fixedly connected between the diverter box 36 and the lifting frame 35. The air inlet end of the bottom end of the pneumatic telescopic rod 37 is connected to the inside of the diverter box 36, so the air pressure inside the pneumatic telescopic rod 37 increases and extends. The two pneumatic telescopic rods 37 extend to push the lifting frame 35 to move upward. One end of the lifting frame 35 is rotatably sleeved on the outside of the metal tube 7. The upwardly moving lifting frame 35 drives the rotatably connected metal tube 7 to move upward. Since the telescopic tube 25 has a telescopic characteristic, the metal tube 7 can move up and down.

[0064] When the metal tube 7 moves upward, the metal tube 7 moves upward with the filter screen 8. At this time, the bottom and top of the inner cavity of the high-temperature smelting furnace 5 are connected through the partition frame 6. The rotating metal tube 7 drives the stirring frame 45 to rotate, stirring the material on the top of the filter screen 8, causing the material on the top of the filter screen 8 to fall, and the alloy material finally enters the bottom of the inner cavity of the high-temperature smelting furnace 5.

[0065] One end of the exhaust pipe 43 is fixedly connected to a solenoid valve 44. After waiting for a period of time, the solenoid valve 44 is controlled to open, and the internal gas of the exhaust pipe 43 is discharged through the solenoid valve 44. The internal air pressure of the diversion box 36 drops, the air pressure telescopic rod 37 retracts, the lifting frame 35 is reset, and the metal tube 7, the filter screen 8, the partition block 9 and the collection frame 10 are reset.

[0066] Finally, the air pump 39 is controlled to stop working, and the valve body 23 stops working, and the vacuuming work at the bottom of the inner cavity of the high-temperature smelting furnace 5 is completed.

[0067] A method for preparing a casting device comprises the following steps:

[0068] Step 1: The alloy material falls to the bottom of the inner cavity of the high-temperature smelting furnace 5 and undergoes high-temperature smelting processing;

[0069] Step 2: The second batch of alloy materials enters the high-temperature melting furnace 5 through the feed valve 4, and the alloy materials fall to the top of the partition frame 6:

[0070] Step 3: Control the water supply component to flush and preheat the second batch of alloy materials using the high temperature inside the high-temperature smelting furnace 5, and use the excess heat to preheat and flush the alloy materials, so as to utilize the heat of the exhaust gas and avoid wasting water resources;

[0071] Step 4: After the liquid alloy material in the high-temperature melting furnace 5 is discharged, the exhaust component is controlled to work to dry the cleaned alloy material;

[0072] Step 5: The exhaust assembly works further to provide power for the lifting structure, the metal tube 7 moves upward, and the alloy material after preheating processing enters the bottom of the inner cavity of the high-temperature smelting furnace 5;

[0073] Step 6: The exhaust component finally works to exhaust the gas inside the high-temperature smelting furnace 5 and control the gas pressure value inside the high-temperature smelting furnace 5;

[0074] Step 7: The high temperature smelting furnace 5 is operated to perform high temperature smelting processing on the alloy material;

[0075] Step 8: Repeat steps 2, 3, 4, 5, 6 and 7. When the alloy material is smelted at high temperature, the heat generated by the smelting is used to preheat the next batch of alloy materials, thereby shortening the processing cycle and reducing equipment cost investment.
