DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1-Figure 5 The present application provides a mixing device, including a mixing component 10.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The mixing assembly 10 includes a mixing tank 110. Specifically, a discharge pipe 140 is provided at the bottom of the mixing tank 110 for discharging materials. A mixing element 120 is installed inside the mixing tank 110. The mixing element 120 includes a driving motor 121. The driving motor 121 is installed at the top of the mixing tank 110. The output end of the driving motor 121 is connected to a stirring rod 122. The bottom end of the stirring rod 122 is movable through the inside of the mixing tank 110 and extends to the inside of the mixing tank 110. A stirring blade 123 is installed on the stirring rod 122. Each stirring blade 123 is provided with a plurality of air flow holes 124 at equal intervals. The stirring rod 122 is located above the stirring blade 123 and is rotatably provided with an arc filter 130. The raw materials are all put into the mixing tank 110, and are filtered through the arc filter 130 at this time. Then the driving motor 121 is started to rotate the stirring rod 122, and then the stirring blade 123 is rotated, so that the raw materials can be stirred and mixed, so as to better extract the rare and precious elements in the raw materials. By setting the driving motor 121, the stirring rod 122 and the stirring blade 123, the raw materials in the mixing tank 110 can be fully stirred, so as to better extract the rare and precious elements in the raw materials. By setting the airflow holes 124 on the stirring blade 123, when the stirring blade 123 is rotated, liquid will pass through the airflow holes 124 to increase the fluidity of the liquid. By setting the arc filter 130, the raw materials entering the mixing tank 110 can be filtered, and the filtering area can be increased to prevent impurities in the raw materials from affecting the enrichment and extraction of rare and precious elements.

[0029] In this embodiment, a fixing plate 150 is disposed in the middle of the arc filter 130, and the stirring rod 122 is rotatably connected to the fixing plate 150. A limiting plate 160 is fixedly connected to the periphery of the arc filter 130, and a mounting plate is fixedly connected to the inner wall of the mixing tank 110, and the limiting plate 160 is disposed on the mounting plate.

When the electric heater 220 is started, the mixing tank 110 can be heated, and then the raw materials in the mixing tank 110 can be heated to accelerate the mixing efficiency.

[0031] In this embodiment, the outer tank 210 includes a first shell 211 and a second shell 212, which are detachably connected to each other and are arranged outside the mixing tank 110. Ear plates 230 are fixedly connected to both sides of the first shell 211 and the second shell 212, and the two sets of ear plates 230 are detachably connected. Connecting bolts 240 are arranged on both sets of ear plates 230. When the electric heater 220 needs to be inspected and maintained, the connecting bolts 240 are unscrewed, and the first shell 211 and the second shell 212 can be removed from the outside of the mixing tank 110, thereby exposing the electric heater 220 for easy maintenance.

[0032] Furthermore, the first shell 211 and the second shell 212 are provided with a heat preservation plate 250 on their exteriors. The heat preservation plate 250 can prevent heat loss and reduce energy consumption.

[0035] The working principle of the mixing device and the rare element enrichment and extraction equipment:

[0036] The raw materials are all put into the mixing tank 110, and then filtered through the arc filter 130, and then the drive motor 121 is started to rotate the stirring rod 122, and then the stirring blade 123 is rotated, so that the raw materials can be stirred and mixed, which is convenient for better extraction of rare and precious elements in the raw materials. Through the setting of the drive motor 121, the stirring rod 122 and the stirring blade 123, the raw materials in the mixing tank 110 can be fully stirred, which is convenient for better extraction of rare and precious elements in the raw materials. Through the airflow holes 124 set on the stirring blade 123, when the stirring blade 123 is rotated, liquid will pass through the airflow holes 124 to increase the fluidity of the liquid. Through the setting of the arc filter 130, the raw materials entering the mixing tank 110 can be filtered, and the filtration area is increased to prevent impurities in the raw materials from affecting the enrichment and extraction of rare and precious elements.
