Description

Technical Field

[0001] This utility model relates to the field of blast furnace smelting, and more specifically, to a blast furnace ore proportioning device. Background Technology

[0002] In the modern steel industry system, blast furnace ironmaking is the core link in iron production. Its production efficiency, product quality and energy consumption directly determine the core competitiveness of steel enterprises. In the process of blast furnace ironmaking, the accuracy of the ore ratio is a key factor affecting the smooth operation of the blast furnace, reducing the coke ratio and improving the quality of molten iron. The ore must be mixed in a specific ratio to ensure uniform permeability of the material layer in the furnace and sufficient reduction reaction, so as to avoid furnace condition fluctuations or substandard iron composition due to imbalance of the ratio.

[0003] However, in the use of existing technology, due to the viscosity of the materials and different material ratios, the materials tend to adhere to the inner wall of the device, resulting in a low degree of mixing. Furthermore, the device needs to be cleaned by workers after use, which increases the labor intensity of workers and affects the accuracy of material ratios. Therefore, a blast furnace ore ratio device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, due to the viscosity of materials and different material ratios, materials tend to adhere to the inner wall of the device, resulting in a low degree of mixing. Furthermore, it requires workers to clean the device after use, which increases the labor intensity of workers and affects the accuracy of material ratios.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a blast furnace ore proportioning device, comprising a device body. A partition is fixedly connected to the inner wall of the device body. A second motor is fixedly connected to the lower surface of the device body. The output end of the second motor rotates through the interior of the partition and is fixedly connected to a limiting block via a coupling. A second transmission rod is fixedly connected to the interior of the limiting block via bolts. Multiple stirring rods are fixedly connected to the outer surface of the second transmission rod. A scraper is fixedly connected to one end of each stirring rod, and the outer surface of the scraper contacts the inner wall of the device body. A conical block is fixedly connected to the top end of the second transmission rod. A conveying device is provided on the lower surface of the device body.

[0006] As a preferred technical solution of this application, the conveying device includes a conveying cylinder, the upper surface of which is fixedly connected to the lower surface of the partition.

[0007] As a preferred technical solution of this application, a material conveying trough is provided inside the device body near the material conveying cylinder, and a limit plate is provided inside the material conveying trough.

[0008] As a preferred technical solution of this application, one end of the feeding cylinder is fixedly connected to a first motor, and the output end of the first motor is fixedly connected to a first transmission rod through a coupling.

[0009] As a preferred technical solution of this application, a hinge is fixedly connected to the outer surface of the first transmission rod, and the outer surface of the hinge is in contact with the inner wall of the conveying cylinder.

[0010] As a preferred technical solution of this application, a support plate is fixedly connected to the upper surface of the device body by bolts, and a limit box is fixedly connected to the upper surface of the support plate.

[0011] As a preferred technical solution of this application, the limiting box is provided with two storage boxes inside, and pressure sensors are fixedly connected to the lower surfaces of the two storage boxes. The lower surfaces of the pressure sensors are fixedly connected to the upper surfaces of the support plate.

[0012] As a preferred technical solution of this application, a limiting groove is provided on one side of each storage box, a baffle is slidably connected inside the limiting groove, a limiting strip is fixedly connected to one side of the storage box, one side of the limiting strip is in contact with the surface of the baffle, and an electric telescopic rod is fixedly connected to one side of the storage box, the output end of the electric telescopic rod is fixedly connected to the surface of the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In the scheme of this application: During use, the material entering the device body falls on the conical surface of the conical block through the conical block set inside the device body. The conical surface is used to disperse the material and avoid the material from accumulating. The second motor drives the stirring rod to rotate, which uniformly stirs the dispersed material, greatly improving the mixing uniformity and ensuring the quality of the mineral mixture. At the same time, the scraper scrapes against the inner wall of the device body while the stirring rod rotates and stirs the material, removing the material adhering to the inner wall in real time. This not only avoids material waste, but also prevents residual material from affecting the accuracy of subsequent mineral proportioning.

[0015] 2. In the solution of this application: during use, the mineral material is stored in the storage box, and then the weight of the material is weighed in real time by the pressure sensor to achieve precise control of the mineral material ratio. The baffle is driven by the electric telescopic rod to move along the limiting groove. Through the inclined structure of the bottom wall of the storage box, the material is smoothly slid out along the inclined slope, avoiding the accumulation of material residue in the storage box, reducing the labor intensity of workers, and improving the accuracy of material ratio.

A conical block 21 is fixedly connected to the top end of the second transmission rod 18, which disperses the material entering the device body 1. A conveying device is provided on the lower surface of the device body 1.

[0028] Furthermore, such as Figure 4 As shown, the conveying device includes a conveying cylinder 2, the upper surface of which is fixedly connected to the lower surface of the partition plate 16. The conveying cylinder 2 serves to convey materials.

[0029] Furthermore, such as Figure 2 , Figure 4 As shown, a material conveying trough 6 is provided inside the main body 1 near the material conveying cylinder 2. A limit plate 5 is provided inside the material conveying trough 6, which serves to block the material.

[0030] Furthermore, such as Figure 4 As shown, a first motor 14 is fixedly connected to one end of the feeding cylinder 2, and a first transmission rod 3 is fixedly connected to the output end of the first motor 14 through a coupling. The first motor 14 drives the first transmission rod 3 to rotate.

[0031] Furthermore, such as Figure 2 , Figure 4 As shown, a hinge 4 is fixedly connected to the outer surface of the first transmission rod 3. The outer surface of the hinge 4 is in contact with the inner wall of the conveying cylinder 2. The hinge 4 is used to push the material inside the conveying cylinder 2.

[0032] Furthermore, such as Figure 4 As shown, a support plate 7 is fixedly connected to the upper surface of the device body 1 by bolts, and a limit box 8 is fixedly connected to the upper surface of the support plate 7.

[0033] Furthermore, such as Figure 4 , Figure 5As shown, the limiting box 8 has two storage boxes 9 inside. Pressure sensors 22 are fixedly connected to the lower surface of both storage boxes 9. The lower surface of the pressure sensors 22 is fixedly connected to the upper surface of the support plate 7.

Using the limiting groove 11, the two baffles 12 move upwards under the limiting action of the limiting strip 13 and the limiting groove 11, allowing the material to slide out of the bottom of the storage box 9 along the slope and into the interior of the device body 1, landing on the surface of the conical block 21. Through the conical structure on the surface of the conical block 21, the material is dispersed on the inner wall of the device body 1. At this time, the second motor 15 is activated, driving the limiting block 17 to rotate. 7 drives the second transmission rod 18 to rotate, causing the stirring rod 19 on the surface of the second transmission rod 18 to stir the material entering the device body 1, increasing the uniformity of the material. At the same time, the scraper 20 contacts and scrapes against the inner wall of the device body 1 to remove the material adhering to the inner wall of the device body 1, cleaning the inner wall of the device body 1. Then, the limiting plate 5 is pulled to allow the stirred material to enter the inside of the conveying cylinder 2 through the conveying trough 6. The first motor 14 is started, and the first motor 14 drives the first transmission rod 3 and the hinge 4 to rotate, causing the hinge 4 to push the material entering the inside of the conveying cylinder 2, so that the material is discharged from the device for further processing. After use, the second transmission rod 18 can be separated from the limiting block 17, and the stirring rod 19 on the surface of the second transmission rod 18 can be replaced and repaired.
