Description

Technical Field

[0001] This utility model belongs to the technical field of molten iron ladle processing equipment, and in particular relates to a drying device for newly built molten iron ladles. Background Technology

[0002] A ladle, also known as a molten iron pot, is used in furnace smelting. The interior of the ladle is lined with refractory bricks and a surface coating. The refractory bricks and surface coating need to be replaced periodically. During the drying process of the refractory bricks and coating, traditional open flame or charcoal fire baking is unsafe and poses a safety hazard. In addition, because the moisture cannot be quickly discharged from the ladle, the drying process takes a long time. Furthermore, after drying with open flame or charcoal fire, the combustion residue inside the ladle needs to be removed, which is time-consuming and labor-intensive, affecting the ladle's usability.

[0003] To address these issues, we provide a drying device for newly constructed molten iron ladles. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for newly constructed molten iron ladles. A set of electric heating tubes is circumferentially arrayed at the upper end of a base ring plate, and a top ring plate is installed at the upper end of the heating tube assembly, thus forming a drying device. The drying device is placed inside the molten iron ladle, where the heating tubes generate heat to heat the inner wall of the ladle, drying the moisture in the coating. This avoids the safety hazards associated with drying with open flames or charcoal fires, and also eliminates combustion residue, saving on cleaning procedures. An exhaust fan is installed inside the top ring plate to blow the dried moisture out of the ladle, thereby accelerating the evaporation of internal moisture and increasing the drying speed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The drying component includes a base ring plate, a top ring plate and a set of heating wire tubes. The set of heating wire tubes is circumferentially arrayed and installed on the lower surface of the top ring plate. The base ring plate is installed at the lower end of the heating wire tube set. The buffer component is installed inside the base ring plate and the exhaust fan is installed inside the top ring plate.

[0007] A further feature of this invention is that a set of exhaust holes are circumferentially arrayed through the surface of the top ring plate.

[0008] A further feature of this invention is that a sleeve is fitted around the outside of the heating wire tube, with the two ends of the sleeve resting on the upper surface of the base ring plate and the lower surface of the top ring plate, respectively, and heat-permeable holes are arranged in a circumferential array on the side wall of the sleeve.

[0009] A further feature of this invention is that a fan shroud is fitted onto the lower end of the inner wall of the top ring plate. The fan shroud has a cylindrical structure, and its height is less than the length of the heating wire tube.

[0010] A further feature of this invention is that the lower side wall of the hood is provided with a circumferential array of ventilation holes, which gradually expand outwards downwards.

[0011] A further embodiment of this invention is that the buffer assembly includes a mounting plate, a top post, and an end cap. The mounting plate is threaded into the ring of the base ring plate. A set of telescopic holes are opened through the surface of the mounting plate. A telescopic cylinder is fixedly installed on the upper end of the mounting plate at the telescopic holes. The top post is vertically slidably sleeved in the telescopic holes. A guide rod is fixedly installed on the upper end of the top post.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 3 This utility model is a drying device for newly built molten iron ladles, including a drying component 1, an exhaust fan 2, and a buffer component 3. The drying component 1 includes a base ring plate 101, a top ring plate 102, and a set of heating wire tubes 103. The drying component 1 is formed by circumferentially arranging a set of heating wire tubes 103 on the upper end of the base ring plate 101 and installing the top ring plate 102 on the upper end of the heating wire tubes 103. The drying component 1 is placed inside the molten iron ladle, and the heating wire tubes 103 generate heat to heat the inner wall of the molten iron ladle, drying the moisture in the coating of the inner wall of the molten iron ladle. This avoids the safety hazards of drying with open flame or charcoal fire, and at the same time, it does not produce combustion residue, eliminating the cleaning process. By setting the exhaust fan 2 inside the ring of the top ring plate 102, the exhaust fan 2 blows the dried moisture out of the molten iron ladle, thereby accelerating the evaporation of internal moisture and increasing the drying speed.

[0027] Specifically, a set of heating wire tubes 103 are circumferentially arrayed and installed on the lower surface of the top ring plate 102, the base ring plate 101 is installed at the lower end of the set of heating wire tubes 103, the buffer assembly 3 is installed inside the ring of the base ring plate 101, and the exhaust fan 2 is installed inside the ring of the top ring plate 102.

[0028] Furthermore, a set of exhaust holes 102a are circumferentially arrayed on the top ring plate 102. The exhaust fan 2 blows external air into the molten iron ladle. After the airflow enters the bottom, it disperses to the surroundings and rises along the inner wall of the molten iron ladle, eventually being discharged from the exhaust holes 102a on the top ring plate 102, while also carrying away moisture.

[0029] Furthermore, a sleeve 103a is fitted around the outside of the heating wire tube 103. The two ends of the sleeve 103a rest on the upper surface of the base ring plate 101 and the lower surface of the top ring plate 102, respectively. The side wall of the sleeve 103a is provided with heat-permeable holes 103a-1 arranged in a circumferential array to support the top ring plate 102 and the base ring plate 101, while allowing the heat from the heating wire tube 103 to pass through the heat-permeable holes 103a-1 to dry the inner wall of the molten iron ladle.

[0030] Furthermore, a fan shroud 102b is fitted onto the lower end of the inner wall of the top ring plate 102. The fan shroud 102b has a cylindrical structure, and its height is less than the length of the heating wire tube 103. After the exhaust fan 2 draws external air into the molten iron ladle, the airflow reaches the upper surface of the base ring plate 101 under the guidance of the fan shroud 102b. After reaching the surface of the base ring plate 101, the airflow disperses to the surroundings and enters the space between the bottom end of the fan shroud 102b and the base ring plate 101, between the outer wall of the fan shroud 102b and the inner wall of the molten iron ladle, and is finally discharged upwards.

[0031] Furthermore, the lower side wall of the shroud 102b is provided with a circumferential array of ventilation holes 102b-1. The ventilation holes 102b-1 gradually expand outwards downwards. Before the airflow blown in by the exhaust fan 2 reaches the base ring plate 101, part of the airflow enters from the ventilation holes 102b-1 between the outer wall of the shroud 102b and the inner wall of the molten iron ladle, to prevent the bottom airflow from generating turbulence and effectively discharging the airflow from between the outer wall of the shroud 102b and the inner wall of the molten iron ladle.

[0032] The operation process in this embodiment is as follows:

[0033] The drying assembly is placed inside the molten iron ladle that needs to be dried. The heating element 103 and the exhaust fan 2 are turned on. The exhaust fan 2 blows outside air into the molten iron ladle. The airflow is guided by the hood 102b to the upper surface of the base ring plate 101. After reaching the surface of the base ring plate 101, the airflow disperses to the surroundings and enters the space between the outer wall of the hood 102b and the inner wall of the molten iron ladle through the gap between the bottom of the hood 102b and the base ring plate 101. Part of the airflow enters the space between the outer wall of the hood 102b and the inner wall of the molten iron ladle through the ventilation hole 102b-1 to prevent turbulence from forming at the bottom. This prevents the airflow from being effectively discharged from the space between the outer wall of the hood 102b and the inner wall of the molten iron ladle. When the airflow flows upward from the space between the outer wall of the hood 102b and the inner wall of the molten iron ladle, it carries away the moisture drying on the inner wall of the molten iron ladle, allowing the moisture to be discharged from the exhaust hole 102a.

[0034] Example 2

[0035] Please see Figures 1 to 5 Based on Embodiment 1, the buffer assembly 3 includes a mounting plate 301, a top connecting post 302, and an end cap 303. The mounting plate 301 is installed inside the ring of the base ring plate 101, the top connecting post 302 is vertically slidably sleeved in the telescopic hole 301a opened on the surface of the mounting plate 301, and the end cap 303 is placed on the top of the telescopic cylinder 301a-1 fixed above the telescopic hole 301a. A buffer spring 302a-1 is fixedly connected to the upper end of the top connecting post 302. When the drying assembly 1 is vertically lowered into the molten iron ladle, the top connecting post 302 first contacts the bottom of the molten iron ladle, and as the drying assembly 1 is continuously lowered, the top connecting post 302 continuously squeezes the buffer spring 302a-1 to prevent the drying assembly 1 from colliding with the bottom of the molten iron ladle and causing damage.

[0036] Specifically, the mounting plate 301 is threaded into the ring of the base ring plate 101. A set of telescopic holes 301a are opened through the surface of the mounting plate 301. A telescopic cylinder 301a-1 is fixedly installed on the upper end of the mounting plate 301 at the telescopic hole 301a. The top connecting post 302 is vertically slidably sleeved in the telescopic hole 301a. A guide rod 302a is fixedly installed on the upper end of the top connecting post 302. The end cover 303 is threaded into the upper end of the telescopic cylinder 301a-1. The guide rod 302a passes through the end cover 303. A buffer spring 302a-1 is sleeved on the outside of the guide rod 302a. The lower end of the buffer spring 302a-1 is fixedly connected to the upper end of the top connecting post 302. The upper end of the buffer spring 302a-1 is fixedly connected to the lower end face of the end cover 303.

[0037] Furthermore, the guide rod 302a has a cap 302a-2 threaded onto one end of the end cap 303.

[0038] The operation process in this embodiment is as follows:

[0039] When the drying component 1 is placed vertically downward into the molten iron ladle, the top connecting post 302 first contacts the bottom of the molten iron ladle. As the drying component 1 is continuously lowered, the top connecting post 302 continuously compresses the buffer spring 302a-1 to prevent the drying component 1 from colliding with the bottom of the molten iron ladle and causing damage.
