Description

A production equipment for low-carbon magnesia-carbon bricks Technical Field

[0001] This utility model relates to the field of low-carbon magnesia-carbon brick production, and in particular to a production equipment for low-carbon magnesia-carbon bricks. Background Technology

[0002] Low-carbon magnesia-carbon bricks are a new type of refractory material designed by optimizing carbon content and composition based on traditional magnesia-carbon bricks, aiming to reduce the impact of carbon on the quality of molten steel. Magnesia-carbon bricks are non-burning composite refractory materials made from high-melting-point alkaline oxide magnesia and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and carbonaceous binders. Non-burning magnesia-carbon bricks are made from high-quality magnesia, special coagulants and additives as auxiliary raw materials, after batching, high-speed mixing, high-pressure pressing, and electric heating drying. They have excellent resistance to slag erosion, slag penetration, thermal shock stability and thermal conductivity.

[0003] Existing magnesia-carbon brick production equipment requires spraying oil into the pressing mold to form an oil film during production. This process involves multiple steps, which increases the loading time of the magnesia-carbon bricks and reduces the production speed. Furthermore, after the raw materials are filled into the mold, the uneven distribution of the raw materials may result in inconsistent densities at different locations in the pressed magnesia-carbon bricks. Summary of the Invention

[0004] The purpose of this invention is to provide a production equipment for low-carbon magnesium-carbon bricks in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A production equipment for low-carbon magnesia-carbon bricks includes a frame, a horizontal plate in the middle of the frame, a brick-making mechanism on the frame, an oiling mechanism and a vibrating and leveling mechanism, the oiling mechanism being located on the upper side of the horizontal plate and the vibrating and leveling mechanism being located on the lower side of the horizontal plate.

[0007] The oiling mechanism includes two L-shaped push rods. Two symmetrical triangular push plates are fixed in the middle of each L-shaped push rod. The lower end of the L-shaped push rod is provided with teeth. Two symmetrical sliding seats are provided between the two L-shaped push rods. Each sliding seat has an arc-shaped frame on the side closer to the L-shaped push rod. Two tension springs are fixed at the ends of the two sliding seats that are far apart from each other. An oil injection pipe is fixed at the ends of the two sliding seats that are close to each other.

[0008] The vibrating mechanism includes two limit seats, each with a striking arm rotatably connected to its lower end. The ends of the two striking arms that are far apart from each other are fixed with a lever, and the ends of the two limit seats that are close to each other are fixed with a push spring.

[0009] Preferably, two sliding seats are slidably connected to the two sides of the top of the horizontal plate, and a concave groove is opened at the end of the sliding seat near the L-shaped push rod, and the arc-shaped frame is rotatably connected in the concave groove.

[0010] Preferably, the limiting seat is slidably connected to the bottom of the horizontal plate, and the two striking arms are each fixed with a striking ball at one end that is close to each other.

[0011] Preferably, a concave through groove is provided at the middle position of both ends of the horizontal plate, and the concave through groove is composed of a pressure groove and a guide groove, and the lower end of the L-shaped push rod is slidably connected in the guide groove.

[0012] Preferably, the brick-making mechanism includes a forming mold, two symmetrical upper pressing molds are provided above the forming mold, upper pressure plates are fixed to the upper ends of the two upper pressing molds, and upper hydraulic cylinders are fixed to the upper ends of the upper pressure plates. Two lower pressing molds are slidably connected inside the forming mold, and lower pressure plates are fixed to the lower ends of the two lower pressing molds. Lower hydraulic cylinders are fixed to the lower ends of the lower pressure plates.

[0013] Preferably, the upper hydraulic cylinder fixing part is fixedly connected to the top of the frame, and the lower hydraulic cylinder fixing part is fixedly connected to the bottom of the frame.

[0014] Preferably, two L-shaped push rods are fixedly connected to both sides of the upper pressure plate.

[0015] The beneficial effects compared with the existing technology are as follows: the pressing and molding position is lubricated by spraying oil through one pressing, which avoids the inconvenience of demolding the magnesia-carbon bricks. It also shortens the entire material filling time. Furthermore, as the L-shaped push rod continues to move downward, the striking arm vibrates and flattens the pressed material, thereby avoiding uneven force on the mold during the pressing of magnesia-carbon bricks.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] As shown in Figures 1-8, a production equipment for low-carbon magnesia-carbon bricks includes a frame 4, a horizontal plate in the middle of the frame 4, and concave through grooves in the middle of both ends of the horizontal plate. The concave through grooves are composed of a pressure groove 5 and a guide groove 6. A brick-making mechanism 1 is provided on the frame 4. The equipment also includes an oiling mechanism 2 and a vibration leveling mechanism 3. The oiling mechanism 2 is located on the upper side of the horizontal plate, and the vibration leveling mechanism 3 is located on the lower side of the horizontal plate.

[0030] In this embodiment: the brick-making mechanism 1 includes a forming mold 17, with two symmetrical upper pressing molds 13 above the forming mold 17. An upper pressing plate 12 is fixed to the upper end of the two upper pressing molds 13, and an upper hydraulic cylinder 11 is fixed to the upper end of the upper pressing plate 12. Two lower pressing molds 14 are slidably connected inside the forming mold 17, and a lower pressing plate 15 is fixed to the lower end of the two lower pressing molds 14. A lower hydraulic cylinder 16 is fixed to the lower end of the lower pressing plate 15. The fixed part of the upper hydraulic cylinder 11 is fixedly connected to the top of the frame 4, and the fixed part of the lower hydraulic cylinder 16 is fixedly connected to the bottom of the frame 4. The upper pressing plate 12 is pushed downward by the telescopic part of the upper hydraulic cylinder 11, and the two upper pressing molds 13 are moved into the forming mold 17 by the upper pressing plate 12. After the magnesia-carbon brick is pressed and formed, the telescopic part of the lower hydraulic cylinder 16 pushes the lower pressing plate 15 to move the two lower pressing molds 14 upward along the inside of the forming mold 17, and the formed magnesia-carbon brick is sent out of the forming mold 17 by the lower pressing molds 14.

[0031] In this embodiment: the oiling mechanism 2 includes two L-shaped push rods 21. The lower ends of the L-shaped push rods 21 are slidably connected to the guide groove 6. Two symmetrical triangular push plates 22 are fixed at the middle position of each L-shaped push rod 21. The lower end of the L-shaped push rod 21 is provided with teeth. Two symmetrical sliding seats 23 are provided between the two L-shaped push rods 21. Each sliding seat 23 is provided with an arc-shaped frame 25 on the side near the L-shaped push rod 21. Two tension springs are fixed at the ends of the two sliding seats 23 that are far apart from each other. An oil spray pipe 24 is fixed at the ends of the two sliding seats 23 that are close to each other. The two sliding seats 23 are slidably connected to the two sides of the top of the horizontal plate. A concave groove is provided at the end of the sliding seat 23 near the L-shaped push rod 21. The arc-shaped frame 25 is rotatably connected in the concave groove. The two L-shaped push rods 21 are respectively fixedly connected to the two sides of the upper pressure plate 12. The upper pressure plate 12 is used to drive the two L-shaped push rods 21. The rods 21 move downward along their respective guide slots 6, and the L-shaped push rods 21 drive the triangular push plates 22 to move synchronously downward to the pressure slot 5. During this process, the inclined surfaces of the triangular push plates 22 pass over the arc surfaces on the upper side of the two arc frames 25, thereby causing the two arc frames 25 to push the corresponding sliding seats 23 to move towards the middle position of the horizontal plate. As the L-shaped push rods 21 move downward, when the upper end of the inclined surface of the triangular push plates 22 corresponds to the end of the arc frame 25, the oil spray pipe 24 on the sliding seat 23 is on the upper side of the forming mold 17, so that the oil spray pipe 24 sprays an oil film onto the inner wall of the forming mold 17, thereby facilitating the demolding of the magnesia-carbon bricks. When the triangular push plates 22 are completely slid into the pressure slot 5, the tension spring will drive the sliding seat 23 and the oil spray pipe 24 to move away from each other, thereby avoiding the collision between the upper pressure mold 13 and the oil spray pipe 24 when they are engaged with the forming mold 17.

[0032] In this embodiment: the vibrating mechanism 3 includes two limiting seats 31, and each limiting seat 31 is rotatably connected to a striking arm 32 at its lower end. The ends of the two striking arms 32 that are far apart from each other are fixed with a toggle frame 33, and the ends of the two limiting seats 31 that are close to each other are fixed with a push spring 34. The limiting seat 31 is slidably connected to the bottom of the horizontal plate, and the ends of the two striking arms 32 that are close to each other are fixed with a striking ball. The downward movement of the L-shaped push rod 21 causes the toggle frame 33 to slide on the teeth, thereby causing the striking arm 32 to swing up and down around the lower end of the limiting seat 31, so that the striking ball on the striking arm 32 strikes the lower pressure mold 14, thereby flattening the blank in the forming mold 17.

[0033] Working principle: In use, the upper hydraulic cylinder 11 is first used to push the upper pressure plate 12 downward. The upper pressure plate 12 drives the two upper pressure molds 13 to move into the forming mold 17. During this process, the upper pressure plate 12 drives the two L-shaped push rods 21 to move downward along their respective guide slots 6. The L-shaped push rods 21 drive the triangular push plate 22 to move synchronously downward below the pressure slot 5. At the same time, the inclined surface of the triangular push plate 22 passes over the arc surface on the upper side of the two arc frames 25, so that the two arc frames 25 push the corresponding sliding seat 23 to move towards the middle position of the horizontal plate. As the L-shaped push rods 21 move downward;

[0034] When the upper end of the inclined surface of the triangular push plate 22 corresponds to the end of the arc frame 25, the oil spray pipe 24 on the sliding seat 23 is positioned on the upper side of the forming mold 17, thereby spraying an oil film onto the inner wall of the forming mold 17 through the oil spray pipe 24. When the triangular push plate 22 is completely slid into the pressure groove 5, the tension spring will cause the sliding seat 23 and the oil spray pipe 24 to move away from each other, thereby avoiding collision between the upper pressure mold 13 and the oil spray pipe 24 when they are engaged with the forming mold 17. Then, the extension and retraction of the upper hydraulic cylinder 11 is stopped, and the raw material to be pressed and molded is poured into the forming mold 17. Inside, the upper die 13 continues to move towards the upper end of the forming die 17. At the same time, as the L-shaped push rod 21 continues to move downward, the actuating frame 33 slides on the teeth, causing the striking arm 32 to swing up and down around the lower end of the limit seat 31, so that the striking ball on the striking arm 32 strikes the lower die 14, thereby flattening the blank in the forming die 17. Meanwhile, the lower end of the upper die 13 abuts against the top of the forming die 17. As the extension and retraction part of the upper hydraulic cylinder 11 continues to push, the raw material in the forming die 17 is pressed and shaped.

[0035] When the raw material is pressed into magnesia-carbon bricks, the extension part of the upper hydraulic cylinder 11 drives the upper pressure plate 12 to move the upper mold 13 out of the forming mold 17. At the same time, the triangular push plate 22 on the L-shaped push rod 21 will move out from the upper side of the concave through groove of the sliding seat 23. During this process, the upper end of the triangular push plate 22 will push the arc frame 25 in the concave through groove to flip upward, and then the triangular push plate 22 will move out of the concave through groove of the sliding seat 23. After the triangular push plate 22 moves out of the concave through groove, the arc frame 25 will flip downward to reset, so that the arc frame 25 can be pushed when the triangular push plate 22 moves downward next time. At the same time, when the L-shaped push rod 21 moves upward, the actuating frame 33 will flip upward with the teeth. At the same time, the limiting seat 31 moves along the horizontal plate to compress the pushing spring 34, so that the actuating frame 33 will disengage from the teeth as the L-shaped push rod 21 moves upward.

[0036] Subsequently, the extension and retraction part of the lower hydraulic cylinder 16 pushes the lower pressure plate 15 to move upward, and the lower pressure plate 15 pushes the two lower pressing molds 14 to move upward along the inner wall of the forming mold 17. The two lower pressing molds 14 are used to send out the pressed magnesia-carbon bricks, and then the next pressing of magnesia-carbon bricks can be carried out.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
