Description

Technical Field

[0001] The utility model relates to a mixing device, in particular to a raw material mixing device for producing spray-formed aluminum alloy materials. Background Art

[0002] At present, spray forming is a process that uses high-pressure inert gas to atomize alloy liquid flow into fine molten droplets, which fly and cool under high-speed airflow and are deposited into blanks before they are completely solidified. It has various advantages of rapid solidification technology, such as fine grains, uniform structure, and the ability to suppress macro-segregation. Therefore, usually sufficient mixing of alloy liquid flow raw materials can make the final product quality higher. A raw material mixing device is required when producing spray-formed aluminum alloy materials.

[0003] In the prior art, when a raw material mixing device for the production of spray-formed aluminum alloy materials is used, an electromagnetic stirrer is generally used to stir and mix the raw materials when melting and mixing the raw materials. The coil winding of the electromagnetic stirrer is prone to heat up after long-term use. If the heat is not dissipated in time, the insulation of the coil winding of the electromagnetic stirrer will age and be damaged. Currently, when the electromagnetic stirrer is cooled, the paired electromagnetic stirrers cannot be cooled at the same time, resulting in the phenomenon that the insulation of the coil winding of the electromagnetic stirrer is aged and damaged due to the untimely heat dissipation, and the service life is short. Now, a raw material mixing device for the production of spray-formed aluminum alloy materials is urgently needed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a raw material mixing device for the production of spray-formed aluminum alloy materials to solve the problems raised in the above-mentioned background technology.

[0022] like Figure 1 As shown, the utility model provides a technical solution: a raw material mixing device for the production of spray-formed aluminum alloy materials, comprising:

[0023] The housing 1 has a mixing chamber 6 at the top of the housing 1, a pair of mounting chambers 7 symmetrically disposed on both sides of the mixing chamber 6, an electromagnetic stirrer 8 disposed inside the mounting chamber 7, a pair of air supply pipes 2 symmetrically disposed on the top of the housing 1 and respectively inserted into the mounting chambers 7, and a plurality of air outlet holes 9 communicating with the mounting chambers 7 are provided at the bottom of the housing 1;

[0024] A curved air guide plate 3 is arranged on the top of the shell 1, and a hollow curved air guide groove 31 is opened inside the curved air guide plate 3.

A pair of air supply pipes 2 are symmetrically arranged on the side wall of the curved air guide plate 3 and are connected with the curved air guide groove 31. A connecting pipe 41 is arranged between the cooler 4 and the curved air guide plate 3. This design uses the cooler 4 to supply air to the inside of the curved air guide groove 31 from the center position of the side wall of the curved air guide plate 3, and then flows out from the pair of air supply pipes 2 symmetrically arranged on the side wall of the curved air guide plate 3 to the inside of a pair of mounting cavities 7 at the same time, thereby simultaneously blowing and cooling a pair of electromagnetic stirrers 8, and the wind that takes away the heat of the electromagnetic stirrer 8 flows out from the air outlet, thereby playing the role of simultaneously blowing and cooling the paired electromagnetic stirrers 8, improving the timeliness of heat dissipation, and avoiding aging and damage of the insulation of the coil winding of the electromagnetic stirrer 8 due to untimely heat dissipation, thereby improving the service life.

[0025] Reference Figure 2 and Figure 3 A hollow groove 81 is provided inside the iron core of the electromagnetic stirrer 8, and a dispersing plate 13 connected to the air supply pipe 2 is provided on the upper side of the inner wall of the installation cavity 7. A plurality of dispersing holes 131 are provided at the bottom of the dispersing plate 13, and a conical guide plate 14 is provided at the center position of the bottom of the dispersing plate 13. A through hole 141 connected to the dispersing plate 13 is provided at the center position of the bottom of the conical guide plate 14.

This design facilitates the support of the shell 1 by using the base 101, while preventing the discharge pipe 11 from contacting the ground.

[0029] Reference Figure 1-Figure 4 As an embodiment of the utility model: when the electromagnetic stirrer 8 needs to be cooled, the staff supplies air to the inside of the arc-shaped air guide groove 31 from the center position of the side wall of the arc-shaped air guide plate 3 by using the air cooler 4, and then flows out from a pair of air supply pipes 2 symmetrically arranged on the side wall of the arc-shaped air guide plate 3 to the inside of a pair of installation cavities 7 at the same time, and the wind is evenly distributed in the installation cavity 7 through a plurality of wind holes 131 under the action of the wind dispersion plate 13, and the wind is guided to the inner wall of the installation cavity 7 under the action of the conical guide plate 14, so as to centrally blow air to dissipate heat and cool down the side wall of the electromagnetic stirrer 8, accelerate the heat dissipation speed, and blow air to the hollow groove 81 under the action of the through hole 141, Thereby, the interior and side walls of the electromagnetic stirrer 8 are cooled by blowing air at the same time, the speed of heat dissipation is accelerated, and the heat dissipation efficiency is improved. A pair of electromagnetic stirrers 8 can be cooled by blowing air at the same time, and the wind that takes away the heat of the electromagnetic stirrer 8 flows out from the air outlet, thereby playing the role of cooling the paired electromagnetic stirrers 8 by blowing air at the same time, improving the timeliness of heat dissipation, avoiding aging and damage of the insulation of the coil winding of the electromagnetic stirrer 8 due to untimely heat dissipation, thereby improving the service life. Among them, a magnetic stirrer is placed in the mixing chamber 6, and under the action of the electromagnetic stirrer 8, the stirrer mixes and stirs the raw materials.
