The advantage of the utility model is that the horizontal continuous casting crystallizer can improve production efficiency.

[0004] Although the technology cools the mold sleeve by means of two coolers, the coolers require a large amount of cooling water and cannot be recycled, which wastes water resources and is not conducive to cost saving. In addition, when the rods are taken out after being formed, they will still maintain a high temperature for a long time. The device does not have a device for cooling the formed rods, which makes it difficult for staff to quickly collect the formed rods, thereby reducing work efficiency. Summary of the invention

And the cooling water droplets after spraying fall on the top of the recycling box, and then flow into the recycling box through the collection holes, completing the recycling of the cooling water.

[0023] Please refer to Figures 1-5 , a horizontal continuous casting crystallizer for ferrosilicon alloy bars, comprising a mold sleeve 1, two coolers 2 are respectively fixedly connected to the top and bottom of the mold sleeve 1, a cooling tank 3 is opened inside the cooler 2, mold grooves 9 are fixedly connected at equal intervals inside the mold sleeve 1, a circulation water tank 5 is fixedly connected to the top of the cooler 2, a support frame 10 is fixedly connected to the outer side of the circulation water tank 5, spray frames 11 are symmetrically slidably connected to the bottom of the support frame 10, a recovery box 15 is fixedly connected to one side of the bottom of the mold sleeve 1, a cooling circulation component is arranged inside the circulation water tank 5, and a transmission component is arranged inside the support frame 10.

[0024] Specifically, the cooling cycle component includes a circulating riser pipe 4. The outer sides of both ends of the mold sleeve 1 near the two ends of the cooling tank 3 are respectively fixedly connected with the circulating riser pipe 4. The two ends of the cooling tank 3 are respectively fixedly connected with the corresponding circulating riser pipe 4 through connecting pipes. The two circulating riser pipes 4 are respectively fixedly connected with a circulating water tank 5 through two water pipes. The two water pipes extend into the circulating water tank 5 and are respectively fixedly connected with a first water pump 6 and a second water pump 7. A refrigerator 8 is installed inside the circulating water tank 5. The transmission component includes a bidirectional lead screw 13. The bidirectional lead screw 13 is rotatably connected inside the support frame 10. The two spray frames 11 are respectively threadedly connected to the outer sides of the bidirectional lead screw 13. A motor 14 is fixedly connected to one side of the outer part of the support frame 10. The output end of the motor 14 extends into the support frame 10 and is fixedly connected with the bidirectional lead screw 13. The top of the recycling box 15 is equidistantly provided with collection holes 16. The inner part of the recycling box 15 extends into the circulating water tank 5 and is fixedly connected with a recycling pipe 17. The bottom of the spray frame 11 is equidistantly fixedly connected with spray nozzles 12. The inner parts of the two spray frames 11 extend into the circulating water tank 5 and are both provided with hoses 18. One end of the hose 18 extends into the circulating water tank 5 and is fixedly connected with a booster pump. One end of the recycling pipe 17 extends into the recycling box 15 and is installed with a water extraction pump.

[0025] Through the above technical solution, when cooling the mold sleeve 1, the first water pump 6, the second water pump 7 and the refrigerator 8 are started by an external controller. The refrigerator 8 can refrigerate the cooling water inside the circulating water tank 5. The first water pump 6 can pump out the cooling water inside the circulating water tank 5 into the two coolers 2. The mold sleeve 1 can be cooled by powder filling through the arc-shaped cooling tank 3, improving the cooling efficiency. Then, the second water pump 7 can pump the cooling water inside the cooling tank 3 into the circulating water tank 5 for refrigeration, realizing the circulating cooling of the mold sleeve 1, keeping the cooling water at a relatively low temperature for a long time, and effectively saving water resources. When the alloy bar is drawn out from the inside of the mold groove 9, the motor 14, the booster pump and the water extraction pump are started by the external controller. Then, the hose 18 can extract the cooling water from the inside of the circulating water tank 5 through the booster pump and spray the cooling water out through the nozzles 12 at the bottom of the spray rack 11, so as to quickly cool the drawn alloy bar, preventing the alloy bar after forming and taking out from remaining at a relatively high temperature for a long time, which makes it difficult for the staff to collect. At the same time, the output end of the motor 14 can drive the bidirectional lead screw 13 to rotate, and it is preset that the output end of the motor 14 rotates reciprocally. The bidirectional lead screw 13 drives the two spray racks 11 to move reciprocally through the thread connection relationship, thus expanding the spraying range of the nozzles 12 on the alloy bar. The cooling water droplets after spraying fall to the top of the recovery tank 15 and then flow into the inside of the recovery tank 15 through the collection holes 16, completing the recovery of the cooling water. Then, the recovery pipe 17 can re-transport the recovered cooling water into the circulating water tank 5 through the water extraction pump, further achieving the recycling of water resources and reducing the production cost. This device can increase the cooling area of the mold sleeve 1 through the arc-shaped cooling tank 3, improve the cooling efficiency, and make the molten iron inside the mold sleeve 1 cool more evenly, thus improving the production quality of the alloy bar. Cooperating with the circulating water tank 5, the cooling water can be recycled, and at the same time, the cooling effect is ensured under the refrigeration of the refrigerator 8. After the formed alloy bar is drawn out, this device can quickly cool it through the reciprocating spray rack 11 and the nozzles 12, preventing the problem that the alloy bar after forming and taking out remains at a relatively high temperature for a long time, which makes it difficult for the staff to collect. And the cooling water droplets after spraying fall to the top of the recovery tank 15 and then flow into the inside of the recovery tank 15 through the collection holes 16, completing the recovery of the cooling water. Then, the recovery pipe 17 can re-transport the recovered cooling water into the circulating water tank 5 through the water extraction pump, further achieving the recycling of water resources and reducing the production cost.

[0026] Specifically, the first water pump 6, the second water pump 7, the refrigerator 8, the motor 14, the booster pump and the water extraction pump are all electrically connected to the external controller. A water changing port is arranged on one side of the outside of the circulating water tank 5.

[0027] Through the above technical solution, the external controller facilitates the staff to quickly control the first water pump 6, the second water pump 7, the cooler 8, the motor 14, the booster pump and the water extraction pump. The external water changing device can be connected through the water changing port to replace the cooling water inside the circulation water tank 5.

[0028] During use, when cooling the mold sleeve 1, the first water pump 6, the second water pump 7 and the refrigerator 8 are started by an external controller. The refrigerator 8 can refrigerate the cooling water inside the circulating water tank 5. The first water pump 6 can pump out the cooling water inside the circulating water tank 5 into the two coolers 2. The mold sleeve 1 can be cooled by powder filling through the arc-shaped cooling groove 3, which improves the cooling efficiency. Then, the second water pump 7 can pump the cooling water inside the cooling groove 3 into the circulating water tank 5 for refrigeration, realizing the circulating cooling of the mold sleeve 1. The cooling water can be kept at a relatively low temperature for a long time, and water resources are effectively saved. When the alloy bar is drawn out from the inside of the mold groove 9, the motor 14, the booster pump and the water extraction pump are started by an external controller. Then, the hose 18 can pump out the cooling water from the inside of the circulating water tank 5 through the booster pump and spray the cooling water through the nozzles 12 at the bottom of the spray rack 11, so as to quickly cool the drawn alloy bar, preventing the alloy bar after forming and taking out from still being at a relatively high temperature for a long time, which makes it difficult for the staff to collect. At the same time, the output end of the motor 14 can drive the bidirectional lead screw 13 to rotate, and it is preset that the output end of the motor 14 rotates reciprocally. The bidirectional lead screw 13 drives the two spray racks 11 to move reciprocally through the thread connection relationship, thus expanding the spraying range of the nozzles 12 on the alloy bar. The cooled water droplets after spraying fall to the top of the recovery box 15 and then flow into the inside of the recovery box 15 through the collection holes 16, completing the recovery of the cooling water. Then, the recovery pipe 17 can pump the recovered cooling water back into the circulating water tank 5 through the water extraction pump, further achieving the recycling of water resources and reducing the production cost. This device can increase the cooling area of the mold sleeve 1 through the arc-shaped cooling groove 3, improve the cooling efficiency, and make the molten iron inside the mold sleeve 1 cool more evenly, thus improving the production quality of the alloy bar. Combined with the circulating water tank 5, the cooling water can be recycled, and at the same time, the cooling effect is ensured under the refrigeration of the refrigerator 8. After the formed alloy bar is drawn out, this device can quickly cool it through the reciprocating spray rack 11 and the nozzles 12, preventing the problem that the alloy bar after forming and taking out is still at a relatively high temperature for a long time, which makes it difficult for the staff to collect. And the cooled water droplets after spraying fall to the top of the recovery box 15 and then flow into the inside of the recovery box 15 through the collection holes 16, completing the recovery of the cooling water. Then, the recovery pipe 17 can pump the recovered cooling water back into the circulating water tank 5 through the water extraction pump, further achieving the recycling of water resources and reducing the production cost. Through the external controller, it is convenient for the staff to quickly control the first water pump 6, the second water pump 7, the refrigerator 8, the motor 14, the booster pump and the water extraction pump. The cooling water inside the circulating water tank 5 can be replaced by connecting an external water changing device through the water changing port.
