[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and using various processing methods to make metals into metal materials with certain properties. Metallurgical technology can be used to obtain various metal raw materials and their products required for production and life. In the process of metallurgical refining, various metallurgical raw materials such as main raw materials, auxiliary raw materials, slag-forming agents and coolants need to be mixed and stirred evenly to ensure the quality of metallurgy.

[0003] A metallurgical material stirring device is now often used to mix and stir the raw materials in the metallurgical refining valley. A coolant is also added during the metallurgical refining. Due to the limited stirring range of the stirring device, the metallurgical raw materials adhering to the inner wall of the stirring drum during the metallurgical refining process cannot be stirred by the stirring device. Therefore, the metallurgical raw materials on the inner wall of the stirring drum solidify without control, which may cause uneven organizational structure of the metal or alloy, thereby affecting the performance of the refined products.

[0004] Based on this, it is necessary to design an anti-solidification mixer for chemical metallurgy to prevent the metallurgical raw materials adhering to the inner wall of the mixing drum from solidifying in an uncontrolled manner. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0019] Embodiment: A chemical metallurgical anti-solidification mixer, such as Figure 1 and Figure 2As shown, it includes a base 1, a stirring tank 3, a first motor 4, a stirring shaft 41, stirring blades 42 and a scraper 5. The stirring tank 3 is installed on the base 1. The stirring tank 3 is a conical design with a cone facing downward. A feeding port 31 for inputting metallurgical raw materials is opened on the top of the stirring tank 3. The first motor 4 is installed on the top of the stirring tank 3. The output shaft of the first motor 4 is connected with a stirring shaft 41 through a coupling. The stirring shaft 41 passes through the top cover of the stirring tank 3 and extends into the stirring tank 3. The longitudinal portion of the stirring shaft 41 extending into the stirring tank 3 is evenly spaced along its circumference. There are at least one group of stirring blades installed at intervals. Each group of stirring blades includes four stirring blades installed on the circumference of the stirring shaft 41. The stirring blades 42 on the sides are driven by the stirring shaft 41 to rotate in the stirring tank 3, and the raw materials in the stirring tank 3 are continuously and fully stirred by the stirring blades 42. The stirring tank 3 is provided with a scraper 5 in contact with the inner wall thereof, and the scraper 5 is fixedly connected to the stirring shaft 41. When the stirring shaft 41 rotates, the scraper 5 rotates with the stirring shaft 41 to scrape off the metallurgical raw materials adhered to the inner wall of the stirring tank 3, and the scraped raw materials are integrated into the raw materials in the stirring tank 3. The metallurgical raw materials in the stirring tank 3 are fully and continuously stirred by the cooperation of the stirring shaft 41 and the stirring blades 42, thereby realizing the anti-solidification stirring function of the metallurgical raw materials.

[0020] like Figure 1 and Figure 4 As shown, it also includes a valve 32, a discharge pipe 8, a second motor 9 and a spiral blade 91. The bottom of the stirring tank 3 is connected to the discharge pipe 8, and a valve 32 for controlling the flow rate therein is installed on the discharge pipe 8. A spiral blade 91 is arranged in the discharge pipe 8. A second motor 9 for driving the spiral blade 91 to rotate to output the metallurgical raw material is installed outside the discharge pipe 8. The second motor 9 drives the spiral blade 91 to rotate. The spiral blade 91 can transport the raw material in the discharge pipe 8 horizontally, and the rotating transportation of the spiral blade 91 can also realize the up-and-down flipping of the raw material, thereby preventing the raw material from solidifying in the discharge pipe 8.

[0021] like Figure 1 and Figure 3 As shown, it also includes a heating bin 6 and a heating gun 7. A heating bin 6 surrounding a discharge pipe 8 is installed on the base 1. A heating gun 7 is arranged on the heating bin 6. The heating gun 7 performs heating operation on the discharge pipe 8. The arrangement of the heating bin 6 can alleviate the loss of heat. A pressure relief port 61 for discharging high-temperature and high-pressure gas is opened on the heating bin 6. When the heating gun 7 sprays flame to heat the discharge pipe 8, the high-temperature and high-pressure gas generated by the flame is discharged from the pressure relief port 61. A baffle 11 is arranged directly above the pressure relief port 61. The baffle 11 is used to guide the high-temperature and high-pressure gas discharged from the pressure relief port 61.

[0022] like Figure 1 and Figure 2As shown, the mixing tank 3 is connected to a gas exhaust pipe 10, and a fan 101 for accelerating the exhaust of gas and a filter 102 for filtering and purifying the exhausted gas are installed in the gas exhaust pipe 10.

[0023] When in use, the stirring shaft 41 is driven to rotate by the first motor 4, and the stirring blades 42 and the scraper 5 rotate synchronously with the stirring shaft 41, so that the stirring blades 42 stir the metallurgical raw materials in the stirring tank 3, and the scraper 5 slides along the inner wall of the stirring tank 3, thereby scraping off the metallurgical raw materials adhering to the inner wall of the stirring tank 3, so as to avoid the metallurgical raw materials adhering to the inner wall of the stirring tank 3 being cooled and solidified before the metallurgical raw materials at other positions in the stirring tank 3, thereby realizing the anti-solidification stirring treatment of the metallurgical raw materials in the stirring tank 3; after the metallurgical raw materials are fully stirred in the stirring tank 3, they are transported to the next In the process, the spiral blade 91 is driven by the second motor 9 to rotate, and the metallurgical raw material is transported during the rotation of the spiral blade 91. The rotation of the spiral blade 91 can not only transport the metallurgical raw material, but also stir it, so as to prevent the metallurgical raw material from solidifying in the discharge pipe 8; the discharge pipe 8 is heated by the heating gun 7 to heat the metallurgical raw material in the discharge pipe 8 to prevent it from solidifying; when the metallurgical raw material is stirred and refined in the stirring tank 3, the harmful gas generated is discharged through the gas exhaust pipe 10, and the filter 102 filters and purifies the gas to prevent it from polluting the air.

[0024] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
