Description

Technical Field

[0001] The utility model relates to the technical field of gypsum powder drying treatment, in particular to a gypsum powder drying treatment mechanism. Background Art

[0002] Gypsum powder drying equipment is a special mechanical device used to remove excess moisture from gypsum. These devices are usually characterized by high efficiency and continuous operation, and can ensure that the gypsum powder reaches a specific dry basis (i.e. the dry moisture content of the gypsum) during the drying process, which is usually between 5% and 10%. There are many types of gypsum powder drying equipment, including but not limited to ovens, rotary drum dryers, fluidized bed dryers, spray dryers and vacuum dryers. These devices each have their own characteristics and applicable scenarios, but the basic working principle is to remove moisture from gypsum through heating and air circulation. Ovens are suitable for low-temperature drying, while rotary drum dryers use rotating drums for efficient drying.

[0003] Gypsum powder drying equipment is generally a horizontal type. Although the horizontal type has a good stirring effect, the hot air is generally blown from one end of the drying equipment to the other end. When the drying equipment is long, the hot air is affected by the temperature when it blows to the other end, resulting in the gypsum powder on the side far away from the air inlet end of the drying equipment being unable to be effectively dried, while the gypsum powder on the side close to the air inlet end of the drying equipment will be over-dried, resulting in uneven drying of the gypsum powder. Therefore, a gypsum powder drying mechanism is proposed. Utility Model Content

When the gypsum powder is dried, start the servo motor 11 to drive the adjustment seat 12 to move to the side away from the stirring and drying barrel 7. At this time, the sealing bottom plate 8 is synchronously driven to move through the adjusting rod 13. At this time, the gypsum powder inside the stirring and drying barrel 7 will fall into the interior of the collecting box 2.
