Refractory chute for easy integral molding

Abstract

This utility model discloses a refractory chute for casting that facilitates integral molding. It includes a mounting frame with a connecting groove running through one side surface and side plates on both sides of the connecting groove. A motor is fixedly mounted on the top surface of the side plates. This utility model guides and conveys material by adding it into the chute, and then guides the material into the casting cavity through the discharge port. By activating the motor fixed to the top of the side plate, a lead screw rotates. Simultaneously, a limiting rod constrains the movement of a moving block, causing the moving block to displace axially along the lead screw. The moving block is linked to the chute via a connecting block, thereby achieving precise adjustment of the chute height. This effectively solves the limitations of traditional fixed chutes, allowing dynamic adjustment of the chute height according to actual production needs. This adapts the chute to different casting heights, casting cavity positions, and diverse production scenarios, significantly improving the equipment's process adaptability and operational applicability, thus facilitating its use.

Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a refractory chute for casting that is easy to form as a whole. Background Technology

[0002] Integral-cast refractory chutes are refractory material diversion devices manufactured using a one-time casting process. They are mainly used for conveying and diverting high-temperature molten metals (such as molten iron and molten steel). These chutes are widely used in industries such as casting and steelmaking, and can significantly reduce metal adhesion and extend their service life.

[0003] The existing Chinese patent with publication number CN222448241U discloses an integrally formed casting chute. The above-mentioned prior art solution has the following defects. Although the above-mentioned technical solution can form a long molten iron flow channel between the casting cavity and the ladle, so that the molten iron can flow into the casting cavity, providing favorable conditions for casting in environments where it is inconvenient to directly cast from the ladle or for multi-ladle casting production, the overall height of the chute in the above-mentioned technical solution is designed to be fixed, which cannot be flexibly adjusted according to actual production needs. This makes it difficult to adapt to the usage requirements of different casting heights, different casting cavity positions, or diverse production scenarios, thus significantly reducing the applicability of the equipment and the process adaptability.

[0005] To address the shortcomings of existing technologies, this utility model provides a refractory chute for casting that is easy to integrally mold, and has the advantages of adjustable height and position, strong adaptability, and convenient use, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a refractory chute for casting that is easy to form as a whole, including a mounting frame, a connecting groove penetrating one side surface of the mounting frame, and side plates on both sides of the connecting groove, a motor fixedly mounted on the top surface of the side plates, and a lead screw fixedly connected to the output end of the motor, a moving block threadedly connected to the lead screw, and a connecting block fixedly connected to one side surface of the moving block through the connecting groove, one end of the connecting block fixedly connected to a chute body, the inner wall of the chute body being provided with a refractory coating, a discharge port on one side of the bottom surface of the chute body, and a high-temperature resistant filter screen below the discharge port, baffles on both sides of the high-temperature resistant filter screen, and a screw penetrating the top surface of the baffles, one end of the screw extending into the interior of threaded holes opened on both sides of the bottom surface of the chute body, and a limiting rod penetrating between the side plates and the moving block.

[0008] Preferably, the high-temperature resistant filter screen is matched with the discharge port, and positioning blocks are provided on both sides of the top surface of the high-temperature resistant filter screen. One end of the positioning block extends into the interior of the positioning groove opened on both sides of the bottom surface of the discharge port. The diameter of the positioning block is smaller than the diameter of the positioning groove, and the positioning block is inserted into the positioning groove.

[0009] Preferably, the screw is threadedly connected to the threaded hole.

[0010] Preferably, a counterweight is provided on one side of the top surface of the mounting bracket, and inserts are provided on both sides of the bottom surface of the counterweight. One end of the insert extends into the interior of the slots opened on both sides of the top surface of the mounting bracket.

[0011] Preferably, a telescopic rod is installed between the groove and the mounting bracket.

[0012] Preferably, the movable block is movably connected to the limiting rod.

[0013] Preferably, the connecting block and the connecting groove are rectangular structures, and the connecting block and the connecting groove are slidably connected.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a refractory chute for casting that is easy to integrally mold, and has the following beneficial effects:

[0016] (1) In this utility model, the material is introduced into the tank to achieve flow and conveying, and the material is introduced into the casting cavity through the discharge port. The motor fixed to the top of the side plate is started to drive the lead screw to rotate. At the same time, the movement of the moving block is constrained by the limit rod, so that the moving block is displaced along the axial direction of the lead screw. The moving block is linked with the tank through the connecting block, thereby realizing the precise adjustment of the tank height. This effectively solves the limitations of the traditional fixed chute. The tank height can be dynamically adjusted according to the actual production needs, so that it can be adapted to different pouring heights, casting cavity positions and diversified production scenarios. This significantly improves the process adaptability and working condition applicability of the equipment, thus making it convenient to use.

[0017] (2) In this utility model, the overall weight of the mounting frame is increased by the counterweight block, which effectively enhances the anti-overturning ability of the tank during operation and ensures the structural stability during the casting process. The high-temperature resistant filter screen filters impurities in the molten material online. Secondly, the threaded locking mechanism enables quick disassembly and assembly. After rotating the screw to disengage it from the threaded hole at the bottom of the tank, the high-temperature resistant filter screen can be moved vertically downward. When the positioning block on the high-temperature resistant filter screen is completely separated from the positioning groove of the discharge port, the high-temperature resistant filter screen can be disassembled, which facilitates the regular cleaning of impurities accumulated on the high-temperature resistant filter screen. This maintains the filtration efficiency and ensures the continuous operation reliability of the equipment. Attached Figure Description

[0027] Please refer to Figure 1-4 A refractory chute for casting, designed for easy integral molding, includes a mounting frame 1. A connecting groove 8 is provided through one side surface of the mounting frame 1, and side plates 3 are provided on both sides of the connecting groove 8. A motor 2 is fixedly mounted on the top surface of the side plates 3, and a lead screw 5 is fixedly connected to the output end of the motor 2. A moving block 6 is threaded onto the lead screw 5, and a connecting block 7 is fixedly connected through the connecting groove 8 on one side surface of the moving block 6. A trough body 9 is fixedly connected to one end of the connecting block 7. The inner wall of the trough body 9 is coated with a refractory coating 10. A discharge port 15 is provided on one side of the bottom surface of the trough body 9, and a high-temperature resistant filter screen 21 is provided below the discharge port 15. Baffles 20 are provided on both sides of the high-temperature resistant filter screen 21, and a screw 19 is provided through the top surface of the baffles 20. One end of the screw 19 extends to both sides of the bottom surface of the trough body 9. Inside the threaded hole 18 on the side, a limiting rod 4 is provided through the moving block 6 between the side plates 3. The material is guided and transported by adding it into the tank 9, and then guided into the casting cavity through the discharge port 15. The motor 2 fixed to the top of the side plate 3 is started, which drives the lead screw 5 to rotate. At the same time, the limiting rod 4 constrains the movement of the moving block 6, causing the moving block 6 to move axially along the lead screw 5. The moving block 6 is linked with the tank 9 through the connecting block 7, thereby realizing the precise adjustment of the height of the tank 9. This effectively solves the limitations of traditional fixed chutes. The height of the tank 9 can be dynamically adjusted according to actual production needs, making it suitable for different pouring heights, casting cavity positions and diverse production scenarios. This significantly improves the process adaptability and working condition applicability of the equipment, making it convenient to use.

[0028] In one embodiment, the high-temperature resistant filter 21 is matched with the discharge port 15. Positioning blocks 17 are provided on both sides of the top surface of the high-temperature resistant filter 21, and one end of the positioning block 17 extends into the interior of the positioning groove 16 opened on both sides of the bottom surface of the discharge port 15. The diameter of the positioning block 17 is smaller than the diameter of the positioning groove 16. The positioning block 17 is inserted into the positioning groove 16, wherein the high-temperature resistant filter 21 filters impurities in the molten material online.

[0029] In one embodiment, the screw 19 is threadedly connected to the threaded hole 18. Then, by rotating the screw 19 to disengage it from the threaded hole 18 at the bottom of the tank 9, the high-temperature filter screen 21 can be moved vertically downward. When the positioning block 17 on the high-temperature filter screen 21 is completely separated from the positioning groove 16 of the outlet 15, the high-temperature filter screen 21 can be disassembled, which facilitates the regular cleaning of the impurities accumulated in the high-temperature filter screen 21, thus maintaining the filtration efficiency and ensuring the continuous reliable operation of the equipment.

[0030] In one embodiment, a counterweight 12 is provided on one side of the top surface of the mounting bracket 1, and inserts 13 are provided on both sides of the bottom surface of the counterweight 12. One end of the insert 13 extends into the interior of the slots 14 opened on both sides of the top surface of the mounting bracket 1. The diameter of the insert 13 is smaller than the diameter of the slot 14. The insert 13 is inserted into the slot 14. The counterweight 12 increases the overall weight of the mounting bracket 1, which effectively enhances the anti-overturning ability of the tank 9 during operation and ensures the structural stability during the casting process.

[0031] In one embodiment, a telescopic rod 11 is installed between the tank 9 and the mounting frame 1. The telescopic rod 11 can support the tank 9, thereby maintaining the stability of the tank 9 during movement.

[0032] In one embodiment, the movable block 6 is movably connected to the limiting rod 4, wherein the movable block 6 can be limited by the use of the limiting rod 4, thereby maintaining the stability of the movable block 6 during the movement process.

[0033] In one embodiment, the connecting block 7 and the connecting groove 8 are rectangular structures. The connecting block 7 and the connecting groove 8 are slidably connected, allowing the connecting block 7 to move within the connecting groove 8, thereby driving the groove 9 to move and facilitating the adjustment of the height position of the groove 9.

[0034] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] In use, materials are fed into the trough 9 for guided transport and then guided into the casting cavity via the discharge port 15. The motor 2, fixed to the top of the side plate 3, is activated, driving the lead screw 5 to rotate. Simultaneously, the limiting rod 4 constrains the movement of the moving block 6, causing it to shift axially along the lead screw 5. The moving block 6 is linked to the trough 9 via the connecting block 7, thus achieving precise adjustment of the trough 9's height. This effectively overcomes the limitations of traditional fixed chutes, allowing for dynamic adjustment of the trough 9's height according to actual production needs. This adapts the equipment to different pouring heights, casting cavity positions, and diverse production scenarios, significantly improving its process adaptability and operational applicability. For ease of use, the counterweight block 12 increases the overall weight of the mounting frame 1, effectively enhancing the anti-overturning ability of the tank 9 during operation and ensuring structural stability during the casting process. The high-temperature resistant filter screen 21 filters impurities in the molten material online. After rotating the screw 19 to disengage it from the threaded hole 18 at the bottom of the tank 9, the high-temperature resistant filter screen 21 can be moved vertically downwards. When the positioning block 17 on the high-temperature resistant filter screen 21 is completely separated from the positioning groove 16 of the discharge port 15, the high-temperature resistant filter screen 21 can be disassembled, facilitating the regular cleaning of impurities accumulated on the high-temperature resistant filter screen 21, maintaining filtration efficiency and ensuring the continuous reliable operation of the equipment.
