Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical mixing technology, specifically a mixer for iron and steel smelting. Background Technology
[0002] Most existing equipment consists of vertical mixing tanks. When using such tanks, the bottom of the tank is in constant contact with molten steel, which often leads to the formation of a layer of steel slag at the bottom, gradually thickening the bottom and causing an imbalance in the steel-to-water ratio. Furthermore, during the mixing process, the molten steel inevitably generates high pressure within the tank due to the high temperature. Therefore, it is necessary to address the issue of high pressure caused by high temperature, which can damage the tank. Thus, a mixer for steel smelting is needed to solve the above problems. Utility Model Content

[0013] 1.

[0021] 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.
[0022] Please see Figure 1-5 A mixer for steel smelting includes: a mounting frame 1, a rotary motor 2 mounted on the top of the mounting frame 1, a rotating shaft 3 connected to the outer wall of the rotary motor 2, a mixing tank 4 sleeved on the outer wall of the rotating shaft 3, a stirring rod 5 connected to the inner wall of the mixing tank 4, a drain outlet 6 provided on the inner wall of the mixing tank 4, a plug 7 sleeved on the inner wall of the drain outlet 6, external teeth 8 connected to the outer wall of the mixing tank 4, a bottom plate 9 provided at the bottom of the mixing tank 4, a support 10 mounted on the outer wall of the bottom plate 9, a driven wheel 11 movably connected to the inner wall of the support 10, a connecting plate 12 connected to the outer wall of the bottom plate 9, a fixing rod 13 fixedly connected to the top of the connecting plate 12, a sealing disc 14 connected to the outer wall of the fixing rod 13, a main flow pipe 15 connected to the outer wall of the sealing disc 14, a branch pipe 16 connected to the outer wall of the main flow pipe 15, and an airflow pipe 17 connected to the outer wall of the sealing disc 14.
[0023] The rotary motor 2 has a rotary shaft 3 connected to its power output shaft, and the outer wall of the rotary shaft 3 is provided with a protrusion. When the rotary motor 2 on the device outputs rotational power, it controls the rotary shaft 3 to rotate. The protrusion on the outer wall of the rotary shaft 3 is then engaged with the inner wall of the mixing tank 4, thereby causing the rotary shaft 3 on the device to drive the mixing tank 4 to rotate synchronously.
[0024] The number of stirring rods 5 is several, and the stirring rods 5 are evenly arranged in the inner wall of the mixing tank 4. When the mixing tank 4 is rotating, the inner cavity of the mixing tank 4 is filled with a large amount of molten steel. Under the rotation and tumbling of the mixing tank 4, the molten steel in the inner cavity of the mixing tank 4 is diluted and mixed with other liquids every time it passes the stirring rods 5.
[0025] The inner wall of the drain outlet 6 is provided with internal threads, and the outer wall of the plug 7 is provided with external threads. By using the meshing of the internal and external threads, the plug 7 is threadedly connected to the inner cavity of the drain outlet 6. Whenever the equipment needs to drain water, the plug 7 is positioned towards the ground, and the tool is used to twist and discharge the molten steel.
[0026] Among them, there are two supporters 10 and two driven wheels 11. The outer walls of the two driven wheels 11 mesh with the outer walls of the outer teeth 8. When the mixing tank 4 on the device rotates under the control of the rotary motor 2, the two driven wheels 11 on the other side away from the rotary motor 2 mesh with the outer teeth 8 to support the entire mixing tank 4, so that the mixing tank 4 rotates at the same speed on both sides.
[0027] The inner wall of the sealing disc 14 is provided with an annular groove, which is connected to the inner and outer walls of the mixing tank 4. The sealing disc 14 on the device is fixed to the ground by the action of the base plate 9 and the fixing rod 13. When the mixing tank 4 rotates, the inner and outer walls are connected to the annular groove of the sealing disc 14, thereby maintaining the flexible rotation of the mixing tank 4.
[0028] There are two branch pipes 16, and the two branch pipes 16 are connected to the same main pipe 15. Different molten steels are delivered to the inner cavity of the main pipe 15 through the two branch pipes 16. The main pipe 15 is connected to the inner cavity of the mixing tank 4, so that different molten steels are delivered to the inner cavity of the mixing tank 4 and then fully mixed in the inner cavity of the mixing tank 4.
[0029] Among them, the outer wall of the airflow pipe 17 is connected to a pressure relief valve 18, and the height of the pressure relief valve 18 is higher than the height of the molten steel in the inner cavity of the mixing tank 4. When the inner cavity of the mixing tank 4 on the device is filled with molten steel, the water level of the molten steel is not higher than the position of the pressure relief valve 18. And when the mixing tank 4 is rotating, the high pressure formed by the high temperature in the inner cavity of the mixing tank 4 is discharged outward from the pressure relief valve 18.
[0030] The working principle is as follows: First, by setting up a rotating motor 2, a diversion pipe 16, a mixing tank 4, and a stirring rod 5, the diversion pipe 16 delivers different types of molten steel to the inner cavity of the mixing tank 4 through the main pipe 15. The mixing tank 4 rotates under the control of the rotating motor 2, and the stirring rod 5 in the inner wall of the mixing tank 4 disperses and mixes the concentrated molten steel. This allows the mixing tank 4 to perform molten steel mixing. As the mixing tank 4 rotates continuously, the molten steel churns within its inner wall, preventing the molten steel from settling at the bottom. Furthermore, by setting up the mixing tank 4, an airflow pipe 17, and a pressure relief valve 18, the mixing tank 4 is designed to prevent the high pressure generated by the high temperature from expanding within the tank during the mixing of high-temperature molten steel. The airflow pipe 17 is connected to the inner cavity of the mixing tank 4, allowing the high pressure generated by the high temperature to be released at the pressure relief valve 18, thus preventing damage to the device from high pressure expansion.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
