Description

Technical Field

[0001] This utility model belongs to the field of smelting furnace technology, and in particular relates to a rolling device for smelting furnaces in submerged arc furnaces. Background Technology

[0002] In the process of smelting in an electric arc furnace, tamping can break up agglomerates. The furnace charge may sinter into lumps at high temperatures, hindering the contact between gas or liquid and the material. Tamping can also break up agglomerates, allowing reactants to mix fully and improving smelting efficiency. However, traditional tamping methods cannot effectively break up the material in the electric arc furnace. Repeated tamping is required, and the tamping cart needs to be moved constantly, making the operation complicated and inefficient. In addition, using a driven tamping rod cannot tumble the material in the electric arc furnace, which can easily cause the material to accumulate and clump together, resulting in uneven heating during smelting.

[0003] To address these issues, we provide a rolling device for smelting in an electric arc furnace, which facilitates the use of a rolling furnace. Utility Model Content

[0004] The purpose of this utility model is to provide a rolling device for tamping in an electric arc furnace. By setting side-rolling turning components on the left and right sides of the fixed shaft seat, the fixed shaft seat is installed at one end of the tamping rod. When the tamping rod is pushed forward, the turning plates in the side-rolling turning components on both sides of the fixed shaft seat rotate, allowing the material in the electric arc furnace to enter between the rolling plates on one side of the turning plate. The material rubs against the fixed shaft column on one side of the turning plate, thereby breaking and dispersing the material. By setting shovel components at the front and rear ends of the fixed shaft seat, when the tamping rod pushes the side-rolling turning components to roll in the electric arc furnace, the shovel components shovel up the material in the electric arc furnace and transfer it to the turning plate for tumbling and dispersing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rolling device for facilitating the smelting of an electric arc furnace. It includes a fixed shaft seat, two sets of side-rolling material-turning assemblies, and two sets of shoveling assemblies. The side-rolling material-turning assembly includes a turning plate and a fixed shaft column. The two sets of side-rolling material-turning assemblies are respectively arranged on the left and right sides of the fixed shaft seat, and the two sets of shoveling assemblies are respectively arranged on the front and rear sides of the fixed shaft seat. One end of the fixed shaft column penetrates the surface of the turning plate, and the end of the fixed shaft column penetrating the turning plate is fixedly connected to the fixed shaft seat. A set of rolling plates is circumferentially arrayed and fixed on the edge of the plate surface away from the fixed shaft seat.

[0006] A further feature of this invention is that a flipping plate is fixedly provided on the side of the rolling plate near the fixed shaft column, and the surface of the flipping plate is perpendicular to the surface of the fixed shaft column.

[0007] A further feature of this invention is that a set of stirring plates are fixedly arranged in a circumferential array on the outer side of the fixed-axis column, and the surface of the stirring plates is perpendicular to the column surface of the fixed-axis column.

[0008] A further feature of this invention is that a hanger is fixedly provided at the upper end of the fixed shaft seat. The hanger is a U-shaped structure with the opening facing downwards. A transition post is sleeved through the horizontal top plate of the hanger. A cap edge is fixedly provided at the lower end of the transition post. A threaded post is fixedly provided at the upper end of the transition post. An installation post is threadedly screwed onto the outer side of the threaded post.

[0009] A further feature of this invention is that the shovel assembly includes a mounting sleeve and a shovel arm. The mounting sleeves of the two shovel assemblies are respectively fixedly sleeved on the front and rear sides of the fixed shaft seat. The middle section of the shovel arm is hinged to the end of the mounting sleeve away from the fixed shaft seat. Shovel plates are fixedly mounted on both ends of the side of the shovel arm away from the mounting sleeve. The shovel plates gradually tilt downwards towards the end away from the mounting sleeve. The two ends of the shovel arm are respectively aligned with the end faces of the two sides of the rolling plates away from the turning disc. The width of the shovel plate is equal to the length of the rolling plate.

[0010] A further feature of this invention is that the upper and lower ends of the mounting sleeve on the side away from the shovel arm are respectively fixed with mating ears, the upper and lower mating ears of the two mounting sleeves are mated with each other, and the mating ears of the two mounting sleeves are spirally screwed together and have tie bolts passing through them.

[0011] A further feature of this invention is that baffle plates are fixedly provided on both sides of the shovel plate.

[0012] This utility model has the following beneficial effects: This invention features side-rolling and tipping assemblies on both sides of a fixed-shaft seat. The fixed-shaft seat is installed at one end of a tamping rod. When the tamping rod is pushed forward, the tipping discs in the side-rolling and tipping assemblies on both sides of the fixed-shaft seat rotate, causing the material in the submerged arc furnace to enter between the rolling plates on one side of the tipping disc. This causes the material to rub against the fixed-shaft column on one side of the tipping disc, thereby breaking and dispersing the material.

[0013] This invention features material shovels installed at both ends of the fixed shaft seat. When the tamping rod pushes the side-rolling material shovels to roll inside the electric arc furnace, the material shovels to lift the material from the furnace and transfers it to the turning plate for tumbling and dispersing.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Please see Figure 1 and Figure 2 This utility model is a rolling device for facilitating the tamping of an electric arc furnace. It includes a fixed shaft seat 1, two sets of side-rolling and turning material assemblies 2, and two sets of shoveling assemblies 3. The side-rolling and turning material assemblies 2 include turning discs 201 and fixed shaft columns 202. By setting the side-rolling and turning material assemblies 2 on the left and right sides of the fixed shaft seat 1, the fixed shaft seat 1 is installed at one end of the tamping rod. When the tamping rod is pushed forward, the turning discs 201 in the side-rolling and turning material assemblies 2 on both sides of the fixed shaft seat 1 rotate, so that the material in the electric arc furnace enters between the rolling plates 201a on one side of the turning disc 201, and the material continuously rubs against the fixed shaft column 202 on one side of the turning disc 201, thereby breaking and dispersing the material. By setting the shoveling assemblies 3 at the front and rear ends of the fixed shaft seat 1, when the tamping rod pushes the side-rolling and turning material assemblies 2 to roll in the electric arc furnace, the shoveling assemblies 3 shovel up the material in the electric arc furnace and transfer it to the turning discs 201 for tumbling and dispersing.

[0023] Specifically, two sets of side-rolling material-turning components 2 are respectively set on the left and right sides of the fixed shaft seat 1, and two sets of shoveling components 3 are respectively set on the front and rear sides of the fixed shaft seat 1. One end of the fixed shaft column 202 penetrates the surface of the turning plate 201, and the end of the fixed shaft column 202 penetrating the turning plate 201 is fixedly connected to the fixed shaft seat 1. A set of rolling plates 201a are fixedly arranged in a circumferential array on the edge of the side plate surface of the turning plate 201 away from the fixed shaft seat 1.

[0024] Furthermore, a flipping plate 201a-1 is fixed on the side of the rolling plate 201a near the fixed axis column 202, and the plate surface of the flipping plate 201a-1 is perpendicular to the cylindrical surface of the fixed axis column 202.

[0025] Furthermore, a set of stirring plates 202a are fixedly arranged in a circumferential array on the outer side of the fixed axis column 202. The surface of the stirring plate 202a is perpendicular to the cylindrical surface of the fixed axis column 202. When the material enters between each rolling plate 201a and rolls, the stirring plate 202a and the turning plate 201a-1 stir and disperse the material.

[0026] The operation process in this embodiment is as follows: Install the fixed shaft seat 1 at one end of the tamping rod, operate the tamping car to push the tamping rod forward, so that the side rolling material turning components 2 on both sides of the fixed shaft seat 1 roll in the electric arc furnace. The material shoveling component 3 at the front end of the rolling fixed shaft seat 1 shovels up the material in the electric arc furnace and conveys it to each rolling plate 201a of the turning plate 201, so that the material continuously rolls between each rolling plate 201a, thereby dispersing the material.

[0027] Example 2 Please see Figures 1 to 5 Based on Embodiment 1, a lifting frame 101 is fixedly provided on the upper end of the fixed shaft seat 1. The shovel assembly 3 includes an mounting sleeve 301 and a shovel arm 302. By rotating the lifting frame 101 and one end of the tamping rod, when the tamping rod moves laterally, the side-rolling material-turning assembly 2 can move laterally accordingly, thereby rolling and dispersing the material in the electric arc furnace laterally. By fixing the mounting sleeve 301 to one end of the fixed shaft seat 1 and hinged the shovel arm 302 to one end of the mounting sleeve 301, shovel plates 302a are fixed at both ends on one side of the shovel arm 302. When the side-rolling material-turning assembly 2 rolls in the electric arc furnace, the shovel plates 302a shovel up the material in the electric arc furnace and convey it to the rolling plates 201a of the turning discs 201 on both sides.

[0028] Specifically, the hanger 101 is a U-shaped structure with the opening facing downwards. The top plate of the hanger 101 is sleeved with a transition post 101a. The lower end of the transition post 101a is fixed with a cap edge 101a-1, and the upper end of the transition post 101a is fixed with a threaded post 101a-2. The outer side of the threaded post 101a-2 is threaded with an installation post 101a-3.

[0029] Furthermore, the mounting sleeves 301 of the two shovel components 3 are respectively fixedly sleeved on the front and rear sides of the fixed shaft seat 1. The middle section of the shovel arm 302 is hinged to the end of the mounting sleeve 301 away from the fixed shaft seat 1. Shovel plates 302a are fixed at both ends on the side of the shovel arm 302 away from the mounting sleeve 301. The shovel plates 302a gradually tilt downwards towards the end away from the mounting sleeve 301. The two ends of the shovel arm 302 are aligned with the end faces of the two roller plates 201a away from the turning plate 201. The width of the shovel plate 302a is equal to the length of the roller plate 201a, so that the material shoveled by the shovel plate 302a can enter between the roller plates 201a on both sides of the turning plate 201.

[0030] Furthermore, the upper and lower ends of the mounting sleeve 301 away from the shovel arm 302 are respectively fixed with docking ears 301a, the upper and lower docking ears 301a of the two mounting sleeves 301 are connected to each other, and the docking ears 301a of the two mounting sleeves 301 are spirally screwed and penetrated by tie bolts 301a-1.

[0031] Furthermore, baffle plates 302a-1 are fixed on both sides of the shovel plate 302a to prevent materials from sliding off the sides when moving on the shovel plate 302a.

[0032] The operation process in this embodiment is as follows: When the tamping rod is pushed forward in the electric arc furnace, the shovel 302a shovels up the material and sends it between the rolling plates 201a of the turning discs 201 on both sides. When it is necessary to replace the shovel arm 302, the fixing bolt 301a-1 is unscrewed from the mating lug 301a and the two mounting sleeves 301 are removed from the fixed shaft seat 1.
