Description

Technical Field

[0001] This utility model belongs to the field of white fused alumina production technology, specifically relating to a receiving device for white fused alumina production. Background Technology

[0002] In the production of white fused alumina, the raw material is smelted at high temperature to obtain a molten liquid in a high-temperature state. This molten liquid needs to be received and cooled by a ladle receiving device. The ladle receiving device mainly consists of a ladle receiving trough and a ladle receiving shell. After flowing out of the electric arc furnace or tilting furnace, the high-temperature molten liquid flows into the ladle receiving shell along the ladle receiving trough. The ladle receiving shell is usually equipped with a lining made of high-temperature resistant material or cooling water pipes, so that the high-temperature molten liquid is cooled in the ladle receiving shell.

[0003] In existing white fused alumina production ladle receiving devices, the ladle receiving groove is generally fixed during use, making it difficult to adjust the distance between the ladle receiving groove and the ladle shell. When the molten metal just begins to flow into the ladle shell through the ladle receiving groove, the large distance between the end of the ladle receiving groove and the ladle shell makes it easy for the molten metal to splash as it falls into the ladle shell. The splashed molten metal not only causes molten metal loss but also easily causes injury to the operator, resulting in insufficient convenience in ladle receiving. Utility Model Content

[0004] The purpose of this invention is to provide a receiving device for white fused alumina production. This device can adjust the end of the receiving groove to rotate upward as the amount of molten liquid in the receiving shell increases. Compared with the fixed receiving groove in the prior art, this device reduces the distance between the end of the receiving groove and the bottom inner wall of the receiving shell when the molten liquid first moves into the receiving shell. This reduces the risk of molten liquid splashing when the molten liquid first enters the receiving shell, which could lead to molten liquid loss and injury to operators, and improves the convenience of receiving the molten liquid.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A receiving device for white fused alumina production includes a base plate and further includes:

[0007] The receiving shell is slidably mounted on the base plate in a vertical direction;

[0008] An adjustment mechanism is provided on a base plate. The adjustment mechanism includes a housing mounted on the base plate. A worm gear and a worm are rotatably connected inside the housing. The worm gear and the worm mesh with each other. A lifting block is fixedly connected to the side of the housing near the worm. The lifting block is threadedly connected to the worm.

[0009] A receiving groove is provided above the receiving shell and is fixedly connected to the worm gear;

[0010] The receiving shell moves downward and then drives the receiving groove to rotate via a lifting block, worm gear and worm wheel to adjust the distance between the receiving groove and the receiving shell.

[0011] The lower end of the housing is fixedly connected to a sliding groove, and the base plate is fixedly connected to a sliding plate. The sliding groove and the sliding plate are slidably connected in the vertical direction. The worm gear includes an upper section rod rotatably connected to the housing. The upper section rod meshes with a worm wheel. The lower end of the upper section rod is slidably connected to a lower section rod in the vertical direction. The lower section rod is rotatably connected to the base plate and threadedly connected to the lifting block.

[0012] The slide groove is provided with a first limiting hole, and the slide plate is provided with a plurality of second limiting holes along the vertical direction. The first limiting hole and the second limiting hole are slidably connected by a limiting pin.

[0013] The lower end of the upper section rod is fixedly connected to a slide bar, and the upper end of the lower section rod is provided with a sliding hole. The slide bar and the sliding hole slide in a vertical direction.

[0014] The lower end of the lower section rod is fixedly connected to a protruding edge, and a groove is fixedly connected to the base plate. The protruding edge and the groove are rotatably engaged. A retaining ring is provided above the protruding edge, and the retaining ring is fixedly connected to the groove.

[0015] A plurality of sliding cylinders are fixedly connected to the receiving shell, and a plurality of sliding columns are fixedly connected to the base plate. The sliding cylinders and sliding columns are slidably connected in the vertical direction, and a spring is connected between the bottom of the sliding cylinder and the base plate.

[0016] The technical effects achieved by this utility model are as follows:

[0017] The adjustment mechanism of this utility model drives the end of the receiving groove to rotate upward as the amount of molten liquid in the receiving shell increases. Compared with the fixed receiving groove in the prior art, the distance between the end of the receiving groove and the bottom inner wall of the receiving shell is smaller when the molten liquid just begins to move into the receiving shell. This reduces the situation of molten liquid splashing when the molten liquid just enters the receiving shell, which would cause molten liquid loss and injury to the operator, and improves the convenience of receiving the package.

[0018] The worm gear and worm in the adjustment mechanism of this utility model have self-locking properties, which reduces the situation where the receiving groove itself rotates and causes the receiving shell to shake up and down, thus improving stability.

[0019] The housing of this invention moves up and down along the base plate, adjusting the height of the receiving groove. This facilitates adjusting the distance between the end of the receiving groove and the inner bottom of the receiving shell in the initial state, thus improving flexibility.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1 to 3 As shown, a receiving device for white fused alumina production includes a base plate 10, and further includes: a receiving shell 20, which is slidably mounted on the base plate 10 in a vertical direction; an adjustment mechanism 30, which is disposed on the base plate 10 and includes a housing 31 mounted on the base plate 10, with a worm gear 32 and a worm 33 rotatably connected inside the housing 31, the worm gear 32 and the worm 33 meshing with each other, a lifting block 34 fixedly connected to the side of the receiving shell 20 near the worm 33, the lifting block 34 being threadedly connected to the worm 33; and a receiving groove 40, which is disposed above the receiving shell 20 and fixedly connected to the worm gear 32.

[0027] It should be noted that several wheels are rotatably mounted on the base plate 10 for the bag receiving device to move on the ground. The bag receiving shell 20 is equipped with an inner liner (not shown in the figure). The inner liner is existing technology and is made of high temperature resistant material to protect the structural integrity of the bag receiving shell 20. It will not be described in detail here. The helix angle of the worm 33 is less than or equal to the equivalent friction angle of the meshing surface of the worm 33 and the worm wheel 32. The worm 33 and the worm wheel 32 have self-locking properties, that is, the worm 33 can drive the worm wheel 32, but the worm wheel 32 cannot drive the worm 33 in the opposite direction. In the initial state, the distance between the end of the bag receiving groove 40 and the bottom inner wall of the bag receiving shell 20 is small.

[0028] In this embodiment, after the molten liquid flows into the receiving shell 20 along the receiving groove 40, it moves downward along the bottom plate 10 under the gravity of the molten liquid. The receiving shell 20 drives the lifting block 34 to move downward. Since the lifting block 34 is threadedly connected to the worm 33, while the lifting block 34 moves downward along the worm 33, it also drives the worm 33 to rotate. This causes the worm 33 to drive the worm wheel 32 to rotate, and the worm wheel 32 to drive the receiving groove 40 to rotate. This causes the end of the receiving groove 40 near the receiving shell 20 to rotate upward and away from the receiving shell 20. As a result, when the molten liquid first moves into the receiving shell 20, the distance between the end of the receiving groove 40 and the bottom inner wall of the receiving shell 20 is relatively small. Compared with existing technologies, this design reduces molten splashing when the molten material first enters the receiving shell 20, thus minimizing molten material loss and operator injury. It also improves the ease of receiving the ladle. As more molten material enters the receiving shell 20, the liquid level gradually rises. Simultaneously, the receiving shell 20 moves downward, and the end of the receiving groove 40 rotates upward, ensuring that the end of the receiving groove 40 is above the molten material surface. This reduces the risk of the molten material submerging the receiving groove 40. Furthermore, the self-locking nature of the worm gear 32 and worm 33 makes it difficult for the receiving groove 40 to rotate on its own, reducing the likelihood of the molten material causing the receiving groove 40 to rotate as it flows through, thus improving stability.

[0029] like Figure 2 and Figure 3 As shown, a sliding groove 51 is fixedly connected to the lower end of the housing 31, and a sliding plate 52 is fixedly connected to the base plate 10. The sliding groove 51 and the sliding plate 52 are slidably connected in the vertical direction. The worm gear 33 includes an upper rod 61 rotatably connected to the housing 31. The upper rod 61 meshes with the worm wheel 32. The lower end of the upper rod 61 is slidably connected to a lower rod 62 in the vertical direction. The lower rod 62 is rotatably connected to the base plate 10 and threadedly connected to the lifting block 34.

[0030] In this embodiment, when it is necessary to adjust the height of the receiving groove 40, the slide 51 slides up and down along the slide plate 52. The slide 51 drives the worm gear 32 and the upper rod 61 to move up and down through the housing 31 to adjust the height of the housing 31. This allows the upper rod 61 to move up and down along the lower rod 62, adjusting the overall length of the worm 33. The worm gear 32 then drives the receiving groove 40 to move up and down to adjust the height of the receiving groove 40. This adjusts the distance between the end of the receiving groove 40 and the bottom inner side of the receiving shell 20 in the initial state, improving flexibility and reducing the splashing of molten metal when it first enters the receiving shell 20. When the receiving shell 20 drives the lifting block 34 to move downward, the lifting block 34 drives the lower rod 62 to rotate, and the lower rod 62 drives the upper rod 61 to rotate, so that the upper rod 61 drives the receiving groove 40 to rotate through the worm gear 32.

[0031] like Figure 2 and Figure 3 As shown, a first limiting hole 53 is provided on the slide groove 51, and a plurality of second limiting holes 54 are provided on the slide plate 52 along the vertical direction. The first limiting hole 53 and the second limiting hole 54 are slidably connected by a limiting pin 55.

[0032] In this embodiment, when it is necessary to adjust the height position of the housing 31, the limiting pin 55 is pulled out from the inside of the first limiting hole 53 and the second limiting hole 54, the slide groove 51 is slid along the slide plate 52 so that the first limiting hole 53 is aligned with the second limiting hole 54 at a suitable position, the limiting pin 55 is inserted into the inside of the first limiting hole 53 and the second limiting hole 54 to limit the slide groove 51 and the slide plate 52, so that the height position of the housing 31 is kept fixed, thereby adjusting the height position of the housing 31 to facilitate adjusting the height position of the receiving groove 40.

[0033] like Figure 2 and Figure 3 As shown, a slider 63 is fixedly connected to the lower end of the upper rod 61, and a sliding hole 64 is provided at the upper end of the lower rod 62. The slider 63 and the sliding hole 64 slide in a vertical direction.

[0034] It should be noted that the cross-sectional shape of the slider 63 and the sliding hole 64 is rectangular.

[0035] In this embodiment, the slider 63 and the sliding hole 64 cooperate to prevent relative rotation between the upper rod 61 and the lower rod 62, so that the lower rod 62 rotates and drives the upper rod 61 to rotate together, and also makes the process of the upper rod 61 sliding up and down along the lower rod 62 more stable.

[0036] like Figure 2 and Figure 3 As shown, a protruding edge 65 is fixedly connected to the lower end of the lower section rod 62, and a groove 66 is fixedly connected to the base plate 10. The protruding edge 65 and the groove 66 are rotatably engaged. A retaining ring 67 is provided above the protruding edge 65, and the retaining ring 67 is fixedly connected to the groove 66.

[0037] It should be noted that the retaining ring 67 is annular, and the inner diameter of the retaining ring 67 is smaller than the diameter of the convex edge 65, while the outer diameter of the retaining ring 67 is larger than the diameter of the convex edge 65.

[0038] In this embodiment, the protruding edge 65 and the groove 66 cooperate to make the rotation of the lower rod 62 along the base plate 10 more stable, and the retaining ring 67 prevents the protruding edge 65 from disengaging from the groove 66, thereby improving stability.

[0039] like Figure 1 As shown, several sliding cylinders 71 are fixedly connected to the casing 20, and several sliding columns 72 are fixedly connected to the base plate 10. The sliding cylinders 71 and the sliding columns 72 are slidably connected in the vertical direction, and a spring 73 is connected between the bottom of the sliding cylinder 71 and the base plate 10.

[0040] In this embodiment, when no molten material is placed in the receiving shell 20, the weight of the receiving shell 20 itself and the elastic force of the spring 73 are balanced, so that the height of the receiving shell 20 remains fixed. When molten material is placed in the receiving shell 20, the receiving shell 20 and the molten material press down on the spring 73, so that the height of the spring 73 decreases, thereby causing the receiving shell 20 to move downward along the base plate 10. The sliding cylinder 71 and the sliding column 72 are slidably connected, making the process of the receiving shell 20 moving along the base plate 10 more stable.

[0041] The working principle of this utility model is as follows: When the molten liquid moves from the receiving groove 40 into the receiving shell 20, the distance between the end of the receiving groove 40 and the bottom inner wall of the receiving shell 20 is small. Compared with the prior art, this reduces the splashing of molten liquid when it first moves into the receiving shell 20, improving the convenience of receiving the ladle. As the amount of molten liquid in the receiving shell 20 increases, the receiving shell 20 moves downward. The receiving shell 20 drives the receiving groove 40 to rotate through the lifting block 34, worm gear 33, and worm wheel 32, causing the receiving groove 40 to... The end rotates upward and away from the receiving shell 20, thereby reducing the possibility of the molten liquid level rising and submerging the receiving groove 40. This ensures that the end of the receiving groove 40 is no longer at its initial height position. Compared with the fixed receiving groove 40 in the prior art, it is easier to adjust the distance between the end of the receiving groove 40 and the receiving shell 20 by rotating the receiving groove 40. Furthermore, since the worm gear 32 and worm 33 have self-locking properties, it reduces the possibility of the receiving groove 40 rotating itself and causing the receiving shell 20 to shake up and down, thus improving stability.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
