Description

Technical Field

[0001] The utility model relates to the technical field of drying boxes, in particular to a calcium carbonate uniform drying box. Background Art

[0002] A calcium carbonate uniform drying oven is a device used to dry calcium carbonate materials, ensuring uniform distribution of temperature and humidity during the drying process, so as to obtain a dry product with stable quality. This drying oven is usually used in industrial production to process large amounts of calcium carbonate powder or granules to remove moisture from them, prevent agglomeration, and improve the convenience of storage and transportation.

[0003] The prior art provides a drying box for processing light calcium carbonate with multiple drying functions (Announcement No.: CN215490898U). The device includes a first protective substrate, a first copper heat conducting plate, a temporary storage box, a supporting seat, a vibration motor, a moisture absorbing sponge sheet and a first industrial electric heating pipe. The vibration motor is installed in the middle position of the lower end face of the drying box, a supporting seat is welded on the lower side of the left end face of the drying box, a temporary storage box is placed on the upper end face of the supporting seat, a first protective substrate is welded on the upper side of the interior of the drying box, a first industrial electric heating pipe is installed inside the first protective substrate, a first copper heat conducting plate is installed on the upper end face of the first protective substrate, and a moisture absorbing sponge sheet is installed on the lower end face of the box cover. This design solves the problem that the original drying box does not have multiple heating capabilities, resulting in poor drying effect. The utility model has a reasonable structure, multiple heating capabilities, good drying effect, simple structure and strong practicality.

[0004] But the device still has the following defects:

[0005] When the device is in use, the feeding hopper cannot control the feeding speed and feeding position when feeding, the raw materials may pile up together, and when the vibration motor vibrates the drying box, the vibration amplitude is small and the raw materials cannot be vibrated evenly. When the vibration amplitude is large, the stability of the device is affected. At the same time, light calcium carbonate is a material with a high specific surface area and porous properties. When heated, a certain amount of dust may be generated. The dust entering the outside air will cause air pollution. Therefore, we need to propose a calcium carbonate uniform drying box.
