Description

Technical Field

[0001] This utility model belongs to the field of metallurgical engineering teaching, specifically a visual teaching converter. Background Technology

[0002] In the field of metallurgical engineering, the vanadium extraction converter is a key piece of equipment. Its core function is to efficiently extract vanadium from vanadium-containing molten iron and simultaneously complete the steel production process. This process relies on selective oxidation technology, which, through precise control of oxidation conditions, preferentially oxidizes vanadium in the molten iron into vanadium slag (mainly composed of V2O5, etc.), while retaining carbon in the molten iron, laying the foundation for subsequent steelmaking steps.

[0003] Traditional teaching methods often rely on two-dimensional engineering drawings or PPT animations, which have low interactivity, lack visualization, and cannot intuitively show the internal structure and operation process of the converter. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a visual teaching converter, which solves the problem that existing teaching methods often rely on two-dimensional engineering drawings or PPT animations, which have low interactivity, lack visualization, and cannot intuitively display the internal structure and operation process of the converter.

[0005] A visual teaching converter includes an outer model mechanism and a glass inner liner mechanism:

[0006] The outer model mechanism includes a lower model component, and an upper model component is provided on the upper side of the lower model component;

[0007] The lower model component includes a lower model, and an observation window is provided at the upper outer side of the lower model;

[0008] The upper model component includes an upper model, and an observation window 2 is provided at the lower outer end of the upper model;

[0009] The glass inner liner mechanism is positioned between the lower and upper models.

[0010] When the lower and upper models are combined and connected, observation window one and observation window two are aligned vertically.

[0011] Preferably, the outer upper edge of the lower model is also provided with an external thread;

[0012] The bottom inner edge of the upper model is also provided with an internal thread;

[0013] The internal and external threads are matched.

[0014] Preferably, a set of fixing holes are also provided on the outer side of the upper model.

[0015] Preferably, both the lower model component and the upper model component are manufactured by milling aluminum alloy.

[0016] Preferably, the glass liner mechanism includes a glass liner assembly and a diverter assembly located within the glass liner assembly;

[0017] The glass liner assembly includes a glass liner body, and a bottom blowing hole is provided at the bottom of the glass liner body;

[0018] The diverter assembly includes a diverter plate, the diverter plate has a plurality of diverting holes in the middle, and a support ring is fixedly connected to the lower edge of the diverter plate.

[0019] The diverter plate is placed horizontally inside the glass liner, and the bottom blow hole and air inlet pipe are sealed together.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The external model, manufactured using milled aluminum alloy, simulates the appearance of a real converter. It also features a perforated observation window, allowing trainees to safely and clearly observe the reaction process inside the converter. Furthermore, the model is divided into upper and lower parts, which can be quickly opened and closed via a threaded connection. It can be quickly assembled and disassembled without additional tools, greatly improving the flexibility and efficiency of teaching demonstrations.

[0022] By using an internal transparent glass tank to simulate the furnace cavity and adding simulated materials such as colored liquids or particles, trainees can operate the converter and oxygen blowing by hand, demonstrating dynamic phenomena such as molten pool surface fluctuations, slag-metal interface fluctuations, and bubble rising under the action of oxygen. This intuitive teaching method not only enhances trainees' sense of participation and interaction but also enables them to gain a deeper understanding of key processes such as decarbonization rate and splash suppression. In addition, the air blowing nozzles installed at the bottom of the model can simulate the bottom blowing process of the converter, blowing gas into the molten pool inside the furnace to enhance molten pool stirring and improve metallurgical reaction efficiency, further enriching the teaching content and improving the teaching effect.

[0023] This utility model provides a safe, efficient, and intuitive teaching tool for metallurgical engineering education, enterprise employee skills training, and process simulation demonstrations. Attached Figure Description

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 3 , Figure 5 As shown:

[0032] Example 1: This utility model provides a visual teaching converter, including an outer model mechanism 1 and a glass inner liner mechanism 2:

[0033] The outer model mechanism 1 includes a lower model component 11, and an upper model component 12 is provided on the upper side of the lower model component 11;

[0034] The lower model component 11 includes a lower model 111, and an observation window 112 is provided at the upper outer side of the lower model 111.

[0035] The upper model component 12 includes an upper model 121, and an observation window 122 is provided at the lower outer end of the upper model 121.

[0036] The glass inner liner mechanism 2 is positioned between the lower model 111 and the upper model 121;

[0037] When the lower model 111 and the upper model 121 are combined and connected, the first observation window 112 and the second observation window 122 are aligned vertically.

[0038] Specifically, the outer upper edge of the lower model 111 is also provided with an external thread 113;

[0039] The bottom inner edge of the upper model 121 is also provided with an internal thread 123;

[0040] The internal thread 123 and the external thread 113 are matched.

[0041] Specifically, a set of fixing holes 124 are also provided on the outer side of the upper model 121.

[0042] Specifically, both the lower model component 11 and the upper model component 12 are manufactured using aluminum alloy milling.

[0043] As can be seen from the above, the lower model component 11 and the upper model component 121 are connected and opened and closed quickly by the engagement of internal and external threads, and can be disassembled and assembled without additional tools.

[0044] The glass inner liner mechanism 2 is positioned between the lower model 111 and the upper model 121 to simulate the furnace cavity and add simulated materials.

[0045] When the observation window 112 on the upper outer side of the lower model 111 and the observation window 2122 on the lower outer side of the upper model 121 are connected together, they are aligned vertically to form a hollow observation window, which facilitates real-time observation of the internal reaction.

[0046] In addition, a set of fixing holes 124 are provided on the outer side of the upper model 121, which can be used to fix or connect other facilities, such as Figure 5 As shown, a set of fixing holes 124 of this teaching converter are rotatably mounted on the support frame 3 via a shaft, and driven to rotate by a motor 4 and a coupling, thereby achieving the effect of simulating a converter;

[0047] Both the lower model component 11 and the upper model component 12 are made of aluminum alloy by milling, which ensures the sturdiness of the model and simulates the appearance of a real converter.

[0048] like Figure 4 As shown:

[0049] Example 2: This example is basically the same as the previous example, except that the glass liner mechanism 2 includes a glass liner assembly 21 and a diversion plate assembly 22 located inside the glass liner assembly 21.

[0050] The glass liner assembly 21 includes a glass liner body 211, and a bottom blowing hole 212 is provided at the bottom of the glass liner body 211.

[0051] The diverter assembly 22 includes a diverter 221, which has a plurality of diverter holes 222 in the middle, and a support ring 223 is fixedly connected to the lower edge of the diverter 221.

[0052] The diverter plate 221 is placed horizontally inside the glass inner liner body 211, and the bottom blowing hole 212 is sealed to the air intake pipe.

[0053] As can be seen from the above, a bottom blowing hole 212 is provided at the bottom of the glass inner liner body 211. The bottom blowing hole 212 is connected to the air inlet pipe and is used to blow gas into the glass inner liner body 211.

[0054] The diverter plate 221 is placed horizontally inside the glass inner liner body 211. Several diverter holes 222 are opened on it to evenly disperse the blown gas. The support ring 223 fixedly connected to the lower edge of the diverter plate 221 plays a supporting and positioning role, preventing the diverter plate 221 from directly contacting the bottom wall of the glass inner liner body 211 and thus blocking the flow of gas.

[0055] When gas is blown into the glass inner liner body 211 through the air inlet pipe and bottom blowing hole 212, it is evenly dispersed through the diversion hole 222 on the diversion plate 221, simulating the bottom blowing process of the converter.

[0056] Meanwhile, colored simulated materials can be added into the glass inner liner 211, and dynamic phenomena such as molten pool surface fluctuations and slag-gold interface fluctuations can be observed through a visualization window to assist in teaching demonstrations.
