[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application embodiment discloses a small-scale stirring platform for fly ash chelating agent test, referring to Figure 1 In this embodiment, the stirring platform includes a platform body 1, a stirring container 2, a driving mechanism, a central stirring shaft 3, a central stirring paddle 31, a stirring paddle 5 surrounding the stirring shaft 4 and a single-sided scraper. The stirring container 2 is installed on the platform body 1, and the stirring container 2 is used to store fly ash; and a heat-insulating lining 21 is installed on the inner side wall of the stirring container 2. The setting of the heat-insulating lining 21 can effectively control the stirring temperature in the stirring container 2.

[0027] The driving mechanism is rotatably arranged on one side of the platform body 1; one end of the central stirring shaft 3 and one end of the surrounding stirring shaft 4 are simultaneously installed at the output end of the driving mechanism, and the central stirring shaft 3 is located in the middle of the driving mechanism, and the surrounding stirring shaft 4 is located on one side of the central stirring shaft 3.

[0028] At the same time, the central stirring paddle 31 is installed at the end of the central stirring shaft 3 away from the driving mechanism; the single-sided scraper stirring paddle 5 is installed around the stirring shaft 4 at the end away from the driving mechanism; when the driving mechanism is flipped, the central stirring paddle 31 and the single-sided scraper stirring paddle 5 are flipped and extended into the stirring container 2, so that the central stirring paddle 31 is located in the middle of the stirring container 2, the single-sided scraper stirring paddle 5 is located on one side of the interior of the stirring container 2, and the single-sided scraper stirring paddle 5 is non-contactly fitted with the side wall of the stirring container 2.

[0029] When the driving mechanism is started, the output end of the driving mechanism drives the single-sided scraper stirring paddle 5 on the stirring shaft 4 to rotate around the central stirring paddle 31, so as to scrape up the agglomerated fly ash on the wall of the stirring container 2 and push it to the center; at the same time, the output end of the driving mechanism drives the central stirring paddle 31 on the central stirring shaft 3 to rotate, so as to push the agglomerated fly ash pushed to the center outward for stirring, thereby adopting a double stirring paddle design of the central stirring paddle 31 and the single-sided scraper stirring paddle 5 to ensure that the stirring intensity is sufficient to cope with the large resistance after the agglomeration of the fly ash is manifested, overcome the stirring dead angle, and thus, under the mutual cooperation of the single-sided scraper stirring paddle 5 and the central stirring paddle 31, the agglomerated fly ash is stirred with high intensity, thereby also being able to improve the stirring efficiency.

[0030] The structure of the single-sided scraper stirring blade 5 and the driving mechanism is described in detail below:

[0031] Specifically, refer to Figure 1 and Figure 2 In the present embodiment, one side shovel wing of the single-sided scraper stirring paddle 5 is a sharp scraper wing 51, and the scraper wing 51 is located at the front side of the rotation direction of the single-sided scraper stirring paddle 5, which can scrape the agglomerated fly ash pushed to the wall of the stirring container 2 away from the wall.

[0032] At the same time, the wing of the single-sided scraper stirring blade 5 on one side away from the scraper wing 51 is a raised and thickened mud turning wing 52, which is located at the rear side of the single-sided scraper stirring blade 5 in the rotational forward direction, and can violently turn up the agglomerated fly ash and push it to the center of the stirring container 2. The reason why the mud turning wing 52 is processed to be thick is that this part needs to withstand greater stirring resistance and is easily damaged.

[0033] Preferably, a reinforcing ridge 53 is installed in the middle of the single-sided scraper stirring paddle 5, and the reinforcing ridge 53 is connected to the shovel handle of the single-sided scraper stirring paddle 5. The arrangement of the reinforcing ridge 53 can enhance the turning effect of the agglomerated fly ash on the one hand, and enhance the overall strength of the single-sided scraper stirring paddle 5 on the other hand.

[0034] In addition, refer to Figure 1 and Figure 3 In this embodiment, the driving mechanism includes a flip arm 6, a fixing frame 61, a driving motor 62, a gear ring 63 and a gear set. The flip arm 6 is rotatably mounted on one side of the platform body 1, and the flip arm 6 can flip toward the stirring container 2; the fixing frame 61 is mounted inside the flip arm 6 on the side away from the platform body 1; the driving motor 62 is mounted in the fixing frame 61, and the output end of the driving motor 62 is fixedly connected to the end of the central stirring shaft 3 away from the central stirring paddle 31, so as to drive the central stirring shaft 3 and the central stirring paddle 31 to rotate and stir.

[0035] At the same time, the gear ring 63 is rotatably mounted on the side of the fixed frame 61 facing the central stirring paddle 31, and the end of the stirring shaft 4 away from the single-sided scraper stirring paddle 5 is fixedly mounted on the outer side of the gear ring 63, and the gear ring 63 is a circular ring structure; the gear set is arranged between the fixed frame 61 and the central stirring shaft 3, and the gear set and the gear ring 63 cooperate with each other to realize the linkage driving the gear ring 63, so that the stirring shaft 4 and the single-sided scraper stirring paddle 5 can be rotated and stirred.

[0036] Specifically, refer to Figure 3 In this embodiment, the gear set includes a central gear 32 and a linkage gear 64. The central gear 32 is mounted on one end of the central stirring shaft 3 close to the driving motor 62. When the central stirring shaft 3 rotates, the central gear 32 can be driven to rotate. There are multiple linkage gears 64, which are evenly mounted on the side of the fixed frame 61 facing the central stirring paddle 31. The linkage gears 64 are respectively located between the central gear 32 and the ring gear 63, and one side of the linkage gears 64 is meshed with the central gear 32 at the same time, and the other side of the linkage gears 64 is meshed with the inner side of the ring gear 63 at the same time.

[0037] When the central stirring shaft 3 drives the central gear 32 to rotate, the central gear 32 also drives the interlocking gears 64 to rotate, and the interlocking gears 64 also drive the gear ring 63 to rotate, so that the central stirring shaft 3 is consistent with the axis surrounding the stirring shaft 4, but the rotation speeds of the two shafts are inconsistent. Therefore, by making the rotation speeds of the two shafts asynchronous, the rotation speeds of the central stirring paddle 31 and the single-sided scraper stirring paddle 5 can be different, thereby enhancing the effect of mutual pushing of stirring.

[0038] Better, refer to Figure 1 In this embodiment, a cover 65 is also installed on the outer side of the flip arm 6; when the flip arm 6 is flipped to the top of the stirring container 2, the cover 65 cooperates with the top of the stirring container 2, so that the cover 65 tightly covers the top of the stirring container 2, thereby achieving a safety and heat preservation effect.

[0039] The implementation principle of a small-scale stirring platform for a fly ash chelating agent test in an embodiment of the present application is as follows: when the fly ash in the stirring container 2 needs to be stirred, the flip arm 6 is flipped so that the central stirring paddle 31 and the single-sided scraper stirring paddle 5 are simultaneously extended into the stirring container 2, and then the drive motor 62 is started. The output end of the drive motor 62 drives the central stirring shaft 3 to rotate, so that the central stirring paddle 31 performs extrapolated stirring on the agglomerated fly ash at the center of the stirring container 2.

[0040] At the same time, during the rotation of the central stirring shaft 3, the central gear 32 is driven to rotate, and the central gear 32 is also driven to rotate the interlocking gears 64, and the interlocking gears 64 are also driven to rotate the ring gear 63, and the ring gear 63 is driven to rotate the single-sided scraper stirring paddle 5 around the stirring shaft 4 around the central stirring paddle 31 to rotate and stir, so as to scrape up the agglomerated fly ash on the wall of the stirring container 2 and push it to the center, thereby completing the process of high-intensity stirring of the agglomerated fly ash in the stirring container 2 by using the central stirring paddle 31 and the single-sided scraper stirring paddle 5 at the same time.
