Description

Technical Field

[0001] The utility model belongs to the technical field of calcium carbonate processing, in particular to an active calcium carbonate stirring and mixing device. Background Art

[0002] Calcium carbonate is a cheap and readily available mineral product that can be widely used in building materials, rubber, plastics, papermaking, paint, daily chemicals and other industries. With the continuous expansion of the application field of calcium carbonate, people's research on calcium carbonate has become more and more in-depth. Calcium carbonate is not only used as a filler, but more as a modifier in modified products, giving its composite materials many excellent properties.

[0003] Since calcium carbonate is prone to sticking together if left for a long time, pouring it directly into a stirring and mixing device will cause uneven mixing of the calcium carbonate, thus affecting the production quality of activated calcium carbonate. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1As shown, an activated calcium carbonate stirring and mixing device comprises a stirring box 11, a stirring mechanism and a box cover 12 connected to the stirring box 11. The stirring box 11 and the box cover 12 are installed together by bolts, so that the inside of the stirring box 11 can be easily cleaned. One end of the stirring mechanism located inside the stirring box 11 is fixedly connected to a grinding table 31. The grinding table 31 is located below the feed port of the box cover 12, so that the calcium carbonate first falls onto the grinding table 31. A filter screen 32 is fixedly sleeved on the outer ring of the grinding table 31. The filter screen 32 is used to intercept the calcium carbonate bonded together. A first connecting rod 41 is fixedly connected to the inner wall of the box cover 12. The first connecting rod 41 and the grinding table 31 are located on the same axis. A grinding block 42 for grinding calcium carbonate is eccentrically fixedly connected to one end of the first connecting rod 41 close to the grinding table 31. The gap between the grinding block 42 and the grinding table 31 is smaller than the filter hole diameter of the filter screen 32, so that the calcium carbonate ground by the grinding block 42 can pass through the filter screen 32.

[0021] like Figure 2 As shown, the grinding block 42 is provided with a rounded corner portion 43 to facilitate the entry of calcium carbonate between the grinding block 42 and the grinding table 31 .

[0022] After the stirring device is started, the grinding table 31 and the filter screen 32 will rotate. Since the grinding block 42 is fixed to the box cover 12 by the first connecting rod 41, the position of the grinding block 42 will not be offset. The rotation of the grinding table 31 will throw the unbonded calcium carbonate into the interior of the mixing box 11 for stirring and mixing, while the bonded calcium carbonate will be brought to the side of the grinding block 42 and enter the middle of the grinding block 42 and the grinding table 31 through the rounded corner 43, so as to be ground. The ground calcium carbonate will pass through the filter screen 32 and fall into the interior of the mixing box 11 for stirring and mixing.

[0023] like Figure 1 As shown, the outer ring fixed sleeve of the first connecting rod 41 is provided with a connecting sleeve 44, and the outer wall of the connecting sleeve 44 is fixedly connected with a cleaning brush 46 through a second connecting rod 45. The second connecting rod 45 and the cleaning brush 46 are connected by bolts, so that the cleaning brush 46 can be easily replaced after it is severely worn. The cleaning brush 46 fits against the inner wall of the filter screen 32, and the calcium carbonate stuck in the filter holes of the filter screen 32 is swept back to the top of the grinding table 31.

[0024] When the grinding table 31 and the filter screen 32 are rotating, some calcium carbonate that has not been ground in time and is stuck together will be thrown into the filter holes of the filter screen 32, blocking it. Since the cleaning brush 46 is in contact with the inner wall of the filter screen 32, the calcium carbonate stuck in the filter holes of the filter screen 32 will be swept back to the top of the grinding table 31 by the cleaning brush 46 in time.

[0025] like Figure 1As shown, the stirring mechanism includes a motor 21 installed on the outer wall of the stirring box 11, and the output end of the motor 21 is fixedly connected to a stirring shaft 22. The end of the stirring shaft 22 away from the motor 21 passes through one side of the stirring box 11 and is fixedly connected to the grinding table 31. The stirring shaft 22 is fixedly connected to a plurality of stirring blades 23, and one side of the stirring shaft 22 is fixedly connected to an L-shaped scraper 24, and the side wall of the L-shaped scraper 24 is in contact with the inner wall of the stirring box 11.

[0026] The starting motor 21 can drive the stirring shaft 22 to rotate. When the stirring shaft 22 rotates, it can drive the stirring blade 23, the L-shaped scraper 24 and the grinding table 31 connected thereto to rotate simultaneously. The rotation of the stirring blade 23 will stir and mix the calcium carbonate inside the stirring box 11, and the rotation of the L-shaped scraper 24 will scrape off the calcium carbonate attached to the inner wall of the stirring box 11, thereby improving the uniformity of stirring and mixing.

[0027] like Figure 1 As shown, the outer wall of the mixing box 11 is fixedly connected with multiple supporting legs 14 and a motor seat 15, and the number of supporting legs 14 is at least four, which is used to improve the stability of the mixing box 11. The motor 21 is installed on the motor seat 15 by bolts, which is convenient for disassembly and maintenance of the motor 21. The feed port of the box cover 12 is clamped with a sealing cover 13, which can prevent dust and other foreign matter from entering the interior of the mixing box 11.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
