Description

Technical Field

[0001] This utility model relates to the field of alumina technology, and in particular to a stirring device for alumina production. Background Technology

[0002] Sodium oxalate is mainly used as a cleaning agent in alumina production to help remove impurities and calcium ions. Sodium oxalate is a white crystalline powder with the chemical formula Na₂C₂O₄. It is hygroscopic, soluble in water but insoluble in ethanol. It exhibits good detergency and calcium ion removal capabilities in alumina production.

[0003] A stirring device for alumina production is disclosed in publication number "CN214915416U". It includes an outer cylinder and an inner cylinder rotatably mounted inside the outer cylinder via a rotating assembly. The inner cylinder contains a stirring assembly, which includes a drive motor and a stirring motor. The outer cylinder has a first inlet at its top and a first outlet at its bottom. The inner cylinder has a second inlet at its top and a second outlet at its bottom. Solenoid valves are installed on the first outlet, the second inlet, and the second outlet. This device mainly comprises an outer cylinder and an inner cylinder. The stirring assembly is located inside the inner cylinder. During use, the stirring assembly can thoroughly stir the alumina production material. Simultaneously, the rotating assembly can drive the inner cylinder to rotate inside the outer cylinder, preventing the alumina production material from sinking to the bottom of the inner cylinder and causing sedimentation.

[0004] While this patent can prevent alumina from sinking to the bottom of the mixing tank during stirring, it requires the addition of sodium oxalate cleaning agent to remove impurities from the alumina during stirring. This causes some alumina to adhere to the stirring blades when the alumina mixes with sodium oxalate, resulting in incomplete cleaning. Furthermore, sodium oxalate is often added directly to the alumina, leading to a faster reaction between the sodium oxalate and the alumina at the top of the mixing tank, while the alumina at the bottom remains unreacted, further hindering thorough cleaning. Therefore, improvements are needed. Utility Model Content

[0070] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a stirring device for alumina production.

[0071] A stirring device for alumina production includes a support tank 1 and a support ring 2, with the support ring 2 fixedly connected to the support tank 1; it also includes: multiple support legs 3 evenly arranged on the support ring 2 and fixedly connected to it; a support cover 4 disposed on the support tank 1 and detachably fixedly connected to it; a feed inlet 5 disposed on the support cover 4 and fixedly connected to it; a feed pipe 6 fixedly connected to the support cover 4; a discharge outlet 7 fixedly connected to the support tank 1; and a drive frame 8 disposed on... The following components are fixedly connected to the support cover 4: a drive motor 9 and a drive frame 8; a drive shaft 10 and a drive motor 9; multiple drive blades 11 evenly arranged on the drive shaft 10 and fixedly connected to the drive shaft 10; a drive plate 12 and a drive blade 11; an opening and closing mechanism on the support cover 4 for intermittently dispensing oxalic acid; and a vibration mechanism on the support barrel 1 for vibrating the drive plate 12.

[0072] Reference Figure 5 In a preferred embodiment, the opening and closing mechanism includes: an opening and closing frame 13, which is disposed on the support cover 4 and fixedly connected to the support cover 4; an opening and closing motor 14, which is disposed inside the opening and closing frame 13 and fixedly connected to the opening and closing frame 13; an opening and closing shaft 15, which is detachably fixedly connected to the output end of the opening and closing motor 14; an opening and closing disc 16, which is fixedly connected to the opening and closing shaft 15; and a rotating component disposed on the opening and closing disc 16.

[0073] This configuration ensures that when the opening and closing motor 14 is running, it drives the opening and closing shaft 15, which is detachably and fixedly connected to the output end of the opening and closing motor 14, to rotate, thereby causing the opening and closing disc 16, which is fixedly connected to the opening and closing shaft 15, to rotate and providing power for the operation of the rotating components.

[0074] Reference Figure 5In a preferred embodiment, the rotating component includes: a first rotating shaft 17, eccentrically disposed on the opening and closing plate 16 and fixedly connected to the opening and closing plate 16; a first rotating plate 18, rotatably connected to the first rotating shaft 17; a rotating block 19, disposed on the first rotating plate 18 and fixedly connected to the first rotating plate 18; multiple second rotating shafts 20, which are evenly disposed on the rotating block 19 and fixedly connected to the rotating block 19; a second rotating plate 21, rotatably connected to the second rotating shafts 20; a third rotating shaft 22, rotatably connected to the second rotating plate 21; and a sliding component disposed on the support cover 4.

[0075] This configuration causes the first rotating plate 18, which is rotatably connected to the first rotating shaft 17, to rotate, causing the rotating block 19, which is fixedly connected to the first rotating plate 18, to move, thereby driving the second rotating plate 21, which is rotatably connected to the second rotating shaft 20, to rotate, thus enabling the sliding component to operate.

[0076] Reference Figure 5 In a preferred embodiment, the sliding component includes: a first sliding frame 23, disposed on the support cover 4 and fixedly connected to the support cover 4; a second sliding frame 24, fixedly connected to the support cover 4; and a sliding plate 25, disposed inside the first sliding frame 23, slidably connected to the first sliding frame 23, slidably connected to the second sliding frame 24, and fixedly connected to the third rotating shaft 22.

[0077] This configuration allows the sliding plate 25, which is fixedly connected to the third rotating shaft 22, to slide within the first sliding frame 23 and the second sliding frame 24, thereby achieving intermittent and uniform dispensing of oxalic acid.

[0078] Reference Figure 4 In a preferred embodiment, the vibration mechanism includes: a vibration frame 26, which is disposed on the support barrel 1 and fixedly connected to the support barrel 1; a motor frame 27, which is fixedly connected to the vibration frame 26; a vibration motor 28, which is fixedly connected to the motor frame 27; a vibration shaft 29, which is detachably fixedly connected to the output end of the vibration motor 28; a vibration plate 30, which is fixedly connected to the vibration shaft 29; and a transmission component disposed on the vibration plate 30.

[0079] This configuration ensures that when the vibration motor 28 is running, it drives the vibration shaft 29, which is detachably and fixedly connected to the output end of the vibration motor 28, to rotate, thereby causing the vibration plate 30, which is fixedly connected to the vibration shaft 29, to rotate and providing power for the operation of the transmission components.

[0080] Reference Figure 4In a preferred embodiment, the transmission component includes: a first transmission shaft 31, eccentrically mounted on the vibrating plate 30 and fixedly connected to the vibrating plate 30; a transmission plate 32, rotatably connected to the first transmission shaft 31; a second transmission shaft 33, rotatably connected to the transmission plate 32; a transmission frame 34, mounted on the vibrating frame 26 and fixedly connected to the vibrating frame 26; a transmission block 35, rotatably connected to the second transmission shaft 33 and slidably connected to the transmission frame 34; and an elastic component, mounted on the transmission block 35.

[0081] This configuration causes the transmission plate 32, which is rotatably connected to the first transmission, to rotate, and the transmission block 35, which is rotatably connected to the second transmission shaft 33, to slide within the transmission frame 34, thereby enabling the elastic component to operate.

[0082] Reference Figure 4 In a preferred embodiment, the elastic component includes: an elastic groove 36 formed on the transmission block 35; an elastic spring 37 fixedly connected to the elastic groove 36; and an elastic block 38 fixedly connected to the elastic spring 37.

[0083] This configuration allows the elastic block 38 to slide into the elastic groove 36 when it comes into contact with the support barrel 1. This causes the elastic spring 37, which is fixedly connected to the elastic block 38, to be compressed, generating elastic potential energy. This vibrates the support barrel 1, causing the support barrel 1 to vibrate while driving the drive plate 12, which in turn causes the objects attached to the drive plate 12 to vibrate and fall off.

[0084] Working principle: In use, the oxalic acid conveying pipe is connected to the feed pipe 6, and the alumina material is fed into the support tank 1 through the feed port 5. Then, the drive motor 9 is started, which drives the drive shaft 10, which is detachably fixed to the output end of the drive motor 9, to rotate. This causes the drive blade 11, which is fixed to the drive shaft 10, to rotate, which in turn drives the drive plate 12 to rotate, stirring the alumina material. Then, the opening and closing motor 14 is started, which drives the opening and closing shaft 15, which is detachably fixed to the output end of the opening and closing motor 14, to rotate. This causes the opening and closing disc 16, which is fixed to the opening and closing shaft 15, to rotate, thereby driving the first rotating plate 18, which is rotatably connected to the first rotating shaft 17, to rotate. This causes the rotating block 19, which is fixed to the first rotating plate 18, to move, which in turn drives the second rotating plate 21, which is rotatably connected to the second rotating shaft 20, to rotate. This causes the sliding plate 25, which is fixed to the third rotating shaft 22, to slide within the first sliding frame 23 and the second sliding frame 24, thereby achieving intermittent and uniform feeding of oxalic acid.

[0085] Next, the vibration motor 28 is started, which drives the vibration shaft 29, which is detachably and fixedly connected to the output end of the vibration motor 28, to rotate. This causes the vibration plate 30, which is fixedly connected to the vibration shaft 29, to rotate, thereby driving the transmission plate 32, which is rotatably connected to the first transmission, to rotate. This causes the transmission block 35, which is rotatably connected to the second transmission shaft 33, to slide within the transmission frame 34. When the elastic block 38 contacts the support barrel 1, it slides into the elastic groove 36, thereby compressing the elastic spring 37, which is fixedly connected to the elastic block 38, generating elastic potential energy. This causes the support barrel 1 to vibrate, and the support barrel 1 vibrates while driving the drive plate 12, causing the objects attached to the drive plate 12 to vibrate and fall off.

[0086] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
