Description

Technical Field

[0001] This utility model relates to the technical field of electrode paste adding equipment for submerged arc furnaces, and in particular to a novel paste hopper device for adding electrode paste to submerged arc furnaces. Background Technology

[0002] In ferroalloy submerged arc furnace smelting, self-grown electrodes require the addition of electrode paste into the electrode shell. The upward heat from inside the furnace then melts and sinters the electrode, achieving the effect of simultaneous sintering and use. Adding electrode paste is a routine operation. First, the electrode shell opening is generally about 2 meters away from the platform, requiring ladder climbing for the operation. The electrode shell surface is cylindrical and made of stainless steel, which is relatively smooth, posing a certain risk to ladder climbing. Second, toxic gases and ash are emitted from the electrode shell opening during sintering of the electrode paste, which can be inhaled in large quantities when near the opening, causing harm to the operator's health over a long period of time. Furthermore, the traditional method of adding electrode paste involves using an electric hoist to lift and transport ton bags containing electrode paste for application. During addition, the paste can leak out from the edge of the electrode shell, which is time-consuming, inefficient, and labor-intensive. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a novel paste hopper device for adding electrode paste to a submerged arc furnace.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A novel paste hopper device for adding electrode paste to a submerged arc furnace includes:

[0006] The paste-filling bucket has a lifting ring on the top feeding port for connection to lifting equipment;

[0007] The leaf-opening disc is located at the bottom of the glue-filling tank. One side of it is hinged to the bottom outlet side wall of the glue-filling tank, and the other side is connected to the glue-filling tank through a quick-opening buckle assembly.

[0008] A cross plate is installed at the top feeding port of the paste-filling bucket, and a lifting ring is installed on the cross plate.

[0009] The quick-opening buckle assembly includes:

[0010] Two snap-fit ​​plates are hinged to the side wall of the glue container at the bottom, and each plate is equipped with a snap-fit ​​interface.

[0011] The two clamping rods have their tops that can be engaged with the clip interfaces on the two clip plates respectively, and their bottoms are connected to the leaf-opening disc.

[0012] The beneficial effects of this utility model are as follows: After the electrode paste is loaded, the electrode paste is transported by lifting the lifting ring with an electric hoist. This reduces the labor intensity of the operators. In addition, this device directly lifts the electrode to the top of the electrode shell with an electric hoist, aligns it, and opens the leaf plate so that the electrode paste falls into the electrode shell. This avoids the previous requirement for personnel to climb ladders to operate, reduces the risk factor, and greatly improves the safety of the operators. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figure 1 As shown, a novel paste hopper device for adding electrode paste to a submerged arc furnace includes: a paste-filling tank 3, with a lifting ring 1 on the top feeding port for connection to a lifting device; and an opening plate 5, located at the bottom of the paste-filling tank 3, with one side hinged to the bottom outlet side wall of the paste-filling tank 3, and the other side connected to the paste-filling tank 3 via a quick-opening snap-fit ​​assembly 4. A cross plate 2 is provided on the top feeding port of the paste-filling tank 3, and the lifting ring 1 is installed on the cross plate 2. The quick-opening snap-fit ​​assembly 4 includes: two snap-fit ​​plates 41, each hinged to the side wall of the paste-filling tank 3 at the bottom, and each having a snap-fit ​​interface; and two snap-fit ​​rollers 42, each capable of snapping into the snap-fit ​​interfaces on the two snap-fit ​​plates 41 at the top, and both connected to the opening plate 5 at the bottom.

[0016] In practical application, after the electrode paste blocks are loaded into the paste-filling bucket 3, the electrode paste is transported by lifting the lifting ring 1 using an electric hoist. This reduces the labor intensity of operators and allows the device to be directly lifted above the electrode shell by the electric hoist. After alignment, the opening disc 5 is opened, allowing the electrode paste blocks to fall into the electrode shell, avoiding the previous requirement for personnel to climb ladders, thus reducing the risk factor and greatly improving the safety of operators. The cross plate 2, made of fully welded steel plates, ensures safety during hoisting operations by being firmly welded to the lifting ring 1 and by facilitating the addition of electrode paste, thereby improving work efficiency. The paste-filling bucket 3 is designed with a large upper diameter and a small lower diameter, resembling a funnel, which effectively controls the speed at which the electrode paste falls into the electrode shell, ensuring that all electrode paste blocks fall into the electrode shell without any leakage.

[0017] The ingenious design of the quick-opening buckle assembly 4 and the leaf-opening disc 5 is the core of this device. When the device is lifted by the electric hoist and aligned with the electrode shell, after confirming the surrounding environment, the quick-opening buckle assembly 4 knocks the buckle plate 41 outward, causing the buckle roller 42 to disengage from the buckle plate 41, which opens the leaf-opening disc 5 below. The electrode paste blocks fall into the electrode shell. After all the electrode paste is loaded, the device is lifted to the fixed position, the horizontal valve is closed, and electrode paste is loaded to prepare for adding electrode paste to the next electrode. This cycle continues.

[0018] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
