Description

Technical Field

[0001] The present invention relates to the technical field of dry-mix mortar preparation, and more particularly to a drying device for preparing dry-mix mortar. Background Art

[0002] Dry-mixed mortar (also called dry-powdered mortar in the early days) is usually called hydraulic cement mixed mortar. It refers to a granular or powdered material made by mixing dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. It is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing.

[0003] The existing dry-mixed mortar preparation generally involves adding water to a certain proportion of the material and then conveying it to a drying drum for drying. The drying drum is generally cylindrical, which makes it inconvenient to discharge the material. The material is likely to remain in the drying drum. The mortar material is likely to clump during transportation, which affects the drying effect during drying. Furthermore, the material in the drying drum cannot be completely dispersed and is likely to pile up, which reduces the drying efficiency and increases energy consumption.

The rotating drive unit 13 drives the conical drying cylinder 3 to rotate, and the hot air drying unit 14 dries the mortar material in the conical drying cylinder 3.

[0019] Specifically, in practical applications, when the mortar material is dried, the inlet and outlet pipes 10 are in the upper position, the connecting joint 7 at the end of the feeding hose 6 is connected to the fixed joint 11 on the inlet and outlet pipes 10, the flap valve 12 is opened, and the mortar material is poured into the feed processing box 2, and the mortar material is filtered through the filter part 8, and the agglomerated mortar material is cut and dispersed through the dispersing part 9, and the mortar material falls onto the guide table 4. Under the guidance of the guide table 4, the mortar material slides to the discharge port 5, and passes through the feed box 2. The hose 6, the connecting joint 7, the fixed joint 11 and the inlet and outlet pipes 10 transport the mortar material into the conical drying cylinder 3. After the mortar material is completely transported into the conical drying cylinder 3, the flap valve 12 is closed, the connecting joint 7 and the fixed joint 11 are disconnected, and the conical drying cylinder 3 is driven to rotate by the rotating drive unit 13. The hot air drying unit 14 dries the mortar material in the conical drying cylinder 3.
