Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to an impurity-removing stirrer for aluminum oxide chemical raw materials. Background Art

[0002] During the production process of alumina, impurities are often mixed into it due to factors such as raw materials and processes, which affect its purity and application performance, so crystallization is required to remove impurities. Crystallization removal uses the principle that the solubility of different substances in a specific solvent changes with temperature. During the crystallization and removal of impurities in alumina, the alumina raw material containing impurities is dissolved in a suitable solvent, and the solution is made to reach an oversaturated state through heating, evaporation and other operations. At this time, the alumina crystallizes first, while the impurities remain in the solution due to their solubility characteristics. Through filtration, washing and other steps, pure alumina crystals can be effectively separated, greatly improving the purity of the alumina.

[0027] See also Figure 1-Figure 5 , the utility model provides the embodiment:

[0028] An alumina chemical raw material impurity removal stirrer comprises a working tank 2, on which a heater 14 is installed;

[0029] A rotating hole is provided at the top of the working tank 2, and an annular groove is provided on the annular inner wall of the rotating hole. A rotating disk 11 is rotatably installed in the annular groove. A motor 10 is provided above the rotating disk 11. A stirring main shaft 15 is fixedly installed on the output shaft of the motor 10. A connecting plate 16 located above the rotating disk 11 is fixedly sleeved on the stirring main shaft 15.

A plurality of circular holes are provided on the top of the rotating disk 11, and the bottom ends of the stirring sub-shaft 12 and the stirring main shaft 15 pass through the corresponding circular holes.

[0030] A cross bar 17 is fixedly installed at the bottom of the two stirring auxiliary shafts 12 that are away from each other, and a cleaning ring 18 is fixedly installed at the side of the two cross bars 17 that are away from each other, and the outer side of the cleaning ring 18 contacts the inner wall of the working tank 2;

[0031] like Figure 2 and Figure 5 As shown, a rectangular groove 22 is provided on the side of the working tank 2, and the width of the rectangular groove 22 is greater than the inner diameter of the working tank 2, so as to ensure that the gate 13 can block the raw materials in the working tank 2.

A moving mechanism is installed on the side of the working tank 2, and the moving mechanism is connected to the gate 13 and the motor 10.

[0033] like Figure 1 and Figure 2 As shown, the moving mechanism includes two mounting plates 6 fixedly mounted on the sides of the working tank 2, horizontal hydraulic telescopic rods 7 are fixedly mounted on the tops of the two mounting plates 6, connecting columns 5 are fixedly mounted on the output ends of the two horizontal hydraulic telescopic rods 7, two L-shaped rods 8 are fixedly mounted on the tops of the connecting columns 5, two vertical hydraulic telescopic rods 23 are fixedly mounted on the tops of the connecting columns 5, a moving groove is opened on the sides of the connecting columns 5, the sides of the gate plate 13 extend into the moving groove, and the two vertical hydraulic telescopic rods 23 pass through the top inner wall of the moving groove and are fixedly connected to the top of the gate plate 13.

The sides of the two sliding sleeves 3 close to each other are fixedly installed with T-shaped plates 1, and the top of the motor 10 is fixedly installed on the bottom of the T-shaped plate 1. The sides of the two sliding sleeves 3 away from each other are rotatably installed with pushing columns 9, and the bottom ends of the two pushing columns 9 are respectively rotatably installed on the ends of the two L-shaped rods 8 away from the connecting column 5; the height of the connection between the pushing column 9 and the sliding sleeve 3 is greater than the height of the connection between the pushing column 9 and the L-shaped rod 8, and the connection between the pushing column 9 and the L-shaped rod 8 is located on the side of the sliding sleeve 3 away from the connecting column 5. The movement of the connecting column 5 drives the two L-shaped rods 8 to move, and the movement of the two L-shaped rods 8 drives the two pushing columns 9 to rotate, so that the two sliding sleeves 3 move upward, and the movement of the two sliding sleeves 3 drives the T-shaped plate 1 to move, and the movement of the T-shaped plate 1 drives the motor 10 to move upward. Since the rotating disk 11 is limited by the annular groove, the movement of the motor 10 drives the connecting plate 16, multiple stirring sub-shafts 12, the stirring main shaft 15, two cross bars 17 and the cleaning ring 18 to move upward. Through the setting of the rotating disk 11, the crystals attached to the multiple stirring sub-shafts 12 and the stirring main shaft 15 can be removed, and through the setting of the cleaning ring 18, the crystals on the inner wall of the working tank 2 can be removed, so that it is easy to use.

The advantage of this arrangement is that the conical hole facilitates the collection of materials to the discharge pipe, thereby facilitating discharge.

[0038] Working principle:

[0039] When in use, feed is carried out through the feed pipe 19, and then the raw materials are heated by starting the heater 14. By starting the motor 10, the stirring main shaft 15, multiple stirring sub-shafts 12, the connecting plate 16 and the rotating disk 11 can be rotated, thereby stirring the raw materials, so that the liquid chemical raw materials are homogenized and stirred. After the evaporation and crystallization are completed, the second valve is opened to discharge the liquid material. When the crystallized material needs to be taken out, the two horizontal hydraulic telescopic rods 7 are started to move the two L-shaped rods 8. The movement of the two L-shaped rods 8 drives the connecting column 5 and the gate plate 13 to move, so that the crystallized material on the gate plate 13 can fall into the discharge pipe and be discharged. The movement of the connecting column 5 drives the two L-shaped rods 8 to move, and the movement of the two L-shaped rods 8 drives the two pushing columns 9 to rotate, so that the two sliding sleeves 3 move upward, and the movement of the two sliding sleeves 3 drives the T-shaped plate 1 to move, and the movement of the T-shaped plate 1 drives the motor 10 to move upward. Since the rotating disk 11 is limited by the annular groove, the movement of the motor 10 drives the connecting plate 16, multiple stirring sub-shafts 12, the stirring main shaft 15, two cross bars 17 and the cleaning ring 18 to move upward. Through the setting of the rotating disk 11, the crystals attached to the multiple stirring sub-shafts 12 and the stirring main shaft 15 can be removed, and through the setting of the cleaning ring 18, the crystals on the inner wall of the working tank 2 can be removed, so that it is easy to use.
