Technical Field

[0001] The utility model relates to the technical field of desulfurized limestone powder storage, in particular to a finished product storage device for desulfurized limestone powder. Background Art

[0002] Lime powder is a white powdery substance whose main component is calcium carbonate. It has a wide range of uses and is usually used in the construction industry. It is also used as food-grade calcium carbonate and is a common calcium supplement. Lime powder is generally obtained by burning limestone and fuel together for a long time. It is widely used in the civil engineering industry. If lime powder is left for too long, it will clump when it comes into contact with air.

[0003] After searching, the publication number CN220392132U is found, which discloses a finished product storage device for desulfurized limestone powder, including a shell, the top outer wall of the shell is fixedly connected with a feed port, the bottom outer wall of the shell is provided with an operation port, the top inner wall of the shell is fixedly connected with a motor, the top inner wall of the shell is fixedly connected with a partition, and the output shaft of the motor is fixedly connected with a fixing rod.

[0004] In the process of realizing the utility model, the inventors found that at least the following problems in the prior art have not been solved: by pressing the limit block and pulling the sleeve rod, the block is engaged with the slot A, and the motor is started at this time. The motor drives the auger to rotate inside the shell, which can prevent the lime powder from being placed in the device for a long time and agglomerating. However, in the storage process of desulfurized limestone powder, the first problem to be solved is not how to crush the agglomerated desulfurized limestone, but how to prevent the desulfurized limestone from agglomerating. Of course, there are desulfurized limestone powder storage tanks with heating plates designed on the market, but during use, the desulfurized limestone powder is prone to uneven heating, and the desulfurized limestone powder still agglomerates.

[0005] Therefore, we propose a finished product storage device for desulfurized limestone powder, which can evenly heat and dehumidify the desulfurized limestone powder. Utility Model Content
