Description

Technical Field

[0001] The utility model belongs to the technical field of submerged arc furnaces, and particularly relates to a steel billet inserting device for treating the surface of materials in a submerged arc furnace. Background Art

[0002] After a submerged arc furnace has been used for a period of time, a certain amount of slag skin and crust and other substances will be generated in the furnace lining. Over time, a "hard shell" will form on the surface of the materials. This "hard shell" will not only affect the temperature rise of the materials and the smoothness of the gas flow in the furnace, but also affect the distribution of the current in the furnace, thus affecting the melting and smelting process of the materials. To solve this problem, measures need to be taken to break the hard shell to ensure the normal smelting and refining of the materials.

[0003] To break these "hard shells", workers need to insert a steel billet into the hard shell and then pry it open to loosen the surface of the materials. The steel billet is generally directly placed at the furnace mouth. The worker inserts the steel billet into the furnace to adjust the direction, and then pushes the tail end of the steel billet with both hands to apply force to pry open the hard shell. However, since the steel billet has no fixed limiting device, it is very easy for the steel billet to be unstable and prone to slipping, seriously affecting the safety of the workers. Therefore, the utility model provides a steel billet inserting device for treating the surface of materials in a submerged arc furnace, aiming to conveniently assist the workers to perform the steel billet inserting operation, effectively pry open the hard shell structure on the surface of the materials in the submerged arc furnace, improve the stability during the use of the steel billet, ensure the safety of the workers' operation, and effectively prevent the risk of the steel billet slipping during use.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A steel billet inserting device for treating the surface of materials in a submerged arc furnace, including a base, a telescopic column is fixed on the top of the base. The telescopic column includes a fixed pipe and an extension pipe. The bottom end of the extension pipe extends into the interior of the fixed pipe and the pipe body can move up and down inside the fixed pipe. Fixing holes are provided on the pipe bodies of both the fixed pipe and the extension pipe, and the pipe bodies of the fixed pipe and the extension pipe are fixed by a pin shaft passing through the fixing holes. A limiting ball is installed inside the top end of the extension pipe. Adjusting holes are provided on the pipe bodies of both sides of the limiting ball at the top end of the extension pipe. The spherical surfaces on both sides of the limiting ball penetrate into the interior of the adjusting holes. A limiting channel is provided inside the limiting ball, and a steel billet is arranged inside the limiting channel. The steel billet penetrates through the limiting channel.

[0006] As a preferred technical solution of the utility model, the adjusting holes are symmetrically arranged, and the aperture of the adjusting hole is smaller than the diameter of the limiting ball and larger than the radius of the limiting ball.

[0007] As a preferred technical solution of the utility model, a handle is fixed at one end of the steel billet, and a prying head is fixed at the other end of the steel billet.

[0008] As a preferred technical solution of the present utility model, the extension pipe includes a frame and side plates, and the side plates and the frame are fixedly connected by welding.

[0009] As a preferred technical solution of the present utility model, the limiting ball is evenly provided with installation cavities on the inner wall of the limiting channel, and ball bearings are installed inside the installation cavities.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model fixes the entire device at the furnace mouth position of the submerged arc furnace through the base, ensuring that the steel drill can accurately penetrate into the interior of the submerged arc furnace body and directly act on the hard shell layer of the material surface, thereby improving the stability during the use of the steel drill, ensuring the safety of the operation process, and significantly improving the prying and crushing efficiency. In addition, the design of this device enables the operator to only apply thrust without additionally fixing the steel drill, effectively preventing the possible slippage phenomenon of the steel drill during insertion, greatly reducing the physical burden of the operator, and further enhancing the overall operation safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] Please refer to Figure 1-2 , the present utility model provides the following technical solutions: A plugging device for the surface treatment of the charge surface of a submerged arc furnace, including a base 1. A telescopic column is fixed on the top of the base 1. The telescopic column includes two major parts, a fixed pipe 2 and an extension pipe 3. The bottom pipe body of the extension pipe 3 is inserted into the fixed pipe 2 and can move up and down flexibly inside it to adapt to different height requirements. To ensure the stability and accuracy of the telescopic column, fixing holes 4 are evenly arranged on the pipe bodies of the fixed pipe 2 and the extension pipe 3. By passing a pin through these fixing holes 4, a firm connection and precise positioning between the fixed pipe 2 and the extension pipe 3 are achieved. In addition, a limiting ball 5 is installed inside the top end of the extension pipe 3. The limiting ball 5 not only plays a role in stabilizing the steel drill 8, but also forms a clever cooperation mechanism with the steel drill 8 through the adjustment holes 6 symmetrically arranged on both sides of it, enabling the limiting ball 5 to adjust the angle inside along with the steel drill 8. The aperture of the adjustment hole 6 is smaller than the diameter of the limiting ball 5 to ensure that the limiting ball 5 will not fall off, and is larger than the radius of the limiting ball 5 to allow the steel drill 8 to have sufficient adjustment range. A limiting channel 7 is also arranged inside the limiting ball 5, which is specially designed to accommodate the steel drill 8, enabling the steel drill 8 to stably penetrate through the limiting channel 7, ensuring that the steel drill 8 has a certain support during use and can also move back and forth, thus realizing the control of the surface treatment of the charge surface of the submerged arc furnace.

[0020] In order to facilitate the staff to apply force and break the hard shell of the charge surface, in this embodiment, as a preferred technical solution of the present utility model, a handle 9 is fixed to one end of the steel drill 8, and a pry head 10 is fixed to the other end of the steel drill 8.

[0021] In order to facilitate the installation of the limiting ball 5, in this embodiment, as a preferred technical solution of the present utility model, the extension pipe 3 includes a frame 11 and a side plate 12, and the side plate 12 and the frame 11 are firmly connected by welding.

[0022] In order to reduce the frictional force between the steel drill 8 and the inner wall of the limiting channel 7 of the limiting ball 5 when the steel drill 8 moves, in this embodiment, as a preferred technical solution of the present utility model, mounting cavities 13 are evenly arranged on the inner wall of the limiting channel 7 where the limiting ball 5 is located, and balls 14 are installed inside the mounting cavities 13.

[0023] In order to install and fix the base 1 and ensure the stability of the overall device during use, in this embodiment, as a preferred technical solution of the present utility model, positioning holes 15 are arranged on both sides of the base 1, and the positioning holes 15 are symmetrically arranged with the telescopic column as the center.

[0024] In summary, when adopting the technical solution of the present utility model, the user needs to tightly hold the handle 9 at one end of the steel drill 8 with both hands, and then apply force to adjust the angle of the pry head 10 at the tail end of the steel drill 8. During the rotation of the steel drill 8, its drill body will drive the limit ball 5 to smoothly rotate in the adjustment holes 6 on both sides of the extension pipe 3 by means of the limit channel 7 inside the limit ball 5, so as to accurately orient the pry head 10 part of the steel drill 8 towards the inside of the submerged arc furnace. Thereafter, apply a thrust force using the handle 9 to insert the pry head 10 part of the steel drill 8 deep into the inside of the submerged arc furnace until it inserts into the hard crust layer on the material surface. Finally, by pushing the steel drill 8 to one side, the hard crust layer can be effectively damaged and pushed away, thereby exposing the bottom material surface.

[0025] Finally, it should be noted that in the present utility model, unless otherwise clearly specified and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly limited, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
