Description

Technical Field

[0001] The utility model relates to the technical field of dry-mix mortar production equipment, in particular to a preparation and mixing device for producing floor dry-mix mortar. Background Art

[0002] Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to a granular or powdery material that is physically mixed in a certain proportion with dried and sieved aggregates, inorganic cementitious materials and additives. It is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing.

[0003] The patent with application number 202321885828.0 discloses a dry-mixed mortar production mixing device with dust removal function, including a dust removal box, a motor and a mixing box. The dust removal box is installed in the middle of the outer wall of the mixing box, and the motor is installed in the middle of the top of the mixing box. A dust suction fan is installed at one end of the inner wall of the dust removal box, and a connecting pipe is installed on the top of the dust suction fan. A connecting block is installed on the outer wall of the connecting pipe, and an arc-shaped protective plate is installed on one side of the connecting block by bolts.

[0004] The dry-mixed mortar production mixing device with dust removal function can restrict and fix the filter frame and the arc-shaped protective plate through the arrangement of the partition plate, the first slide groove, the second slide groove and the box door, so as to ensure the dust removal effect during the use of the dry-mixed mortar production mixing device. However, there are still areas that can be improved. For example, the device adopts a single stirring structure, and the raw materials tend to concentrate toward the edge, which leads to a low degree of overall mixing and stirring of the raw materials. At the same time, the raw materials in simple passive stirring are prone to agglomeration, and the agglomerated raw materials are not easily broken up by a single stirring motion, which cannot meet current needs.
