[0002] In the alumina production process, stirring is a crucial step, directly impacting product quality and production efficiency. With the continuous expansion of alumina production scale and increasingly stringent process requirements, higher demands are being placed on the performance of stirring equipment.

[0003] Currently, existing alumina production mixing equipment has some shortcomings in terms of agitator replacement and installation. For example, the agitator replacement process is complicated and usually requires the use of multiple tools for tedious disassembly and installation, which consumes a lot of time and effort and affects the production schedule. In view of this, we propose a dual-shaft high-efficiency mixing equipment for alumina production. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model proposes a dual-shaft high-efficiency stirring device for alumina production, including a stirring tank 1. The top of the stirring tank 1 is detachably connected to a tank cover 2. The inner wall of the tank cover 2 is rotatably connected to a rotating shaft 3. The tank cover 2 is provided with a quick-release assembly 4. There are two sets of rotating shafts 3, and each set of rotating shafts 3 is provided with a corresponding quick-release assembly 4. The quick-release assembly 4 includes a fixed seat 41. The top of the tank cover 2 is fixedly connected to the fixed seat 41. The inner wall of the fixed seat 41 is slidably connected to a sliding rod 42. One end of the sliding rod 42 is fixedly connected to an adjusting plate 43, and the other end of the sliding rod 42 is fixedly connected to a retaining seat 44. The fixed seat 41 and the retaining seat 44 are elastically connected by a spring. The inner wall of the rotating shaft 3 is slidably connected to a connecting arc block 45. The outer wall of the connecting arc block 45 is fixedly connected to a positioning plate 46, and a positioning hole is opened on the positioning plate 46.

[0028] In this utility model, a limiting ring 47 is sleeved on the outer wall of the rotating shaft 3, and a positioning rod 48 is fixedly connected to the bottom of the limiting ring 47. The positioning rod 48 can slide into the positioning hole. A connector 49 is fixedly connected to the outer wall of the connecting arc block 45. A limiting groove is opened on the card seat 44. The limiting ring 47 can rotate at the limiting groove, but cannot move up and down. Multiple sets of connectors 49 are provided.

[0029] Furthermore, a placement groove 5 is provided on the rotating shaft 3, and the outer wall of the connecting arc block 45 is slidably connected to the inner wall of the placement groove 5. The placement groove 5 can be used to place and store the connecting arc block 45. The placement groove 5 and the connecting arc block 45 are elastically connected by a spring. A guide hole 6 is provided on the rotating shaft 3, and the placement groove 5 and the guide hole 6 communicate with each other. A guide rod 7 is fixedly connected to the outer wall of the connecting arc block 45, and the outer wall of the guide rod 7 is slidably connected to the inner wall of the guide hole 6. The guide rod 7 guides the movement of the connecting arc block 45. A stirring paddle 8 is sleeved on the outer wall of the rotating shaft 3, and a connecting hole 9 is provided on the stirring paddle 8. The connector 49 can slide into the connecting hole 9.

[0030] Furthermore, a mounting bracket 10 is fixedly connected to the top of the tank cover 2, and a motor 11 is fixedly connected to the top of the mounting bracket 10. The output end of the motor 11 is fixedly connected to the top of the rotating shaft 3. Two sets of motors 11 are provided, corresponding to two sets of rotating shafts 3. A feed inlet 12 is provided on the tank cover 2, and a discharge pipe 13 is fixedly connected to the bottom of the mixing tank 1. Material is added from the feed inlet 12 and discharged through the discharge pipe 13.

[0031] When using the agitator 8, we pull the adjusting plate 43 to move the retaining seat 44 away from the rotating shaft 3, so that the limiting ring 47 leaves the limiting groove of the retaining seat 44, thereby releasing the limiting state of the limiting ring 47. By sliding the limiting ring 47 upward, the positioning rod 48 leaves the positioning hole on the positioning plate 46, thereby releasing the positioning state of the connecting arc block 45. At this time, we push the connecting arc block 45 to slide it into the placement groove 5, which drives the connector 49 to move synchronously, so that the connector 49 leaves the connecting hole 9, thereby releasing the connection state between the connector 49 and the agitator 8, making it convenient for us to remove the agitator 8.

[0032] During installation, first press the connecting arc block 45 to slide it into the placement groove 5, then slide multiple stirring paddles 8 onto the rotating shaft 3, and then move each stirring paddle 8 to its corresponding connector 49. Release the connecting arc block 45, and the connecting arc block 45 will return to its original position via the reset of spring two. At this time, the connector 49 will slide into the connecting hole 9, completing the connection between the connector 49 and the stirring paddle 8. To ensure the installation is secure, move the limiting ring 47 so that the positioning rod 48 on the limiting ring 47 engages with the positioning hole on the positioning plate 46, thus fixing the positioning plate 46. At this time, the outer wall of the limiting ring 47... The positioning plate 46 is attached to the positioning plate 46 to fix the position of the connecting arc block 45. In order to prevent the limiting ring 47 from leaving the positioning plate 46, when moving the limiting ring 47 to attach to the positioning plate 46, the adjusting plate 43 must be moved first to drive the card seat 44 to move and make room so that the limiting ring 47 can attach to the positioning plate 46. After releasing the adjusting plate 43, the card seat 44 is reset by the spring 1. At this time, the limiting ring 47 is located in the limiting groove of the card seat 44, ensuring that the limiting ring 47 cannot leave the positioning plate 46. In this way, the installation of multiple stirring paddles 8 can be completed quickly at one time, improving work efficiency.

[0033] The device has two sets of rotating shafts 3 (hereafter referred to as shaft A and shaft B). Both rotating shafts 3 are equipped with quick-release components 4. The difference between the two is that the positions of the connectors 49 are different, that is, the connectors 49 at shaft A and shaft B are not at the same height. This way, after the agitator 8 is installed, the agitator 8 of the two shafts will not interfere with each other. Thus, when the agitator 8 is installed, the operator only needs to install the agitator 8 at the position of the connector 49, without having to worry about whether the position of the agitator 8 is installed incorrectly.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
