Dry-mixed mortar production raw material drying and screening treatment system

Abstract

The invention relates to a dry-mixed mortar production raw material drying and screening treatment system which comprises a material screening box, a material collecting box and a drying device. The material collecting box is arranged under the material screening box, the lower end of the material collecting box is connected with the existing ground, and the drying device is arranged between the upper end of the material collecting box and the lower end of the material screening box. Dry-mixed mortar production raw materials in the falling process can be dried through hot air flow, mounting rods drive trapezoidal blocks to ascend and descend, wedge-shaped blocks do linear motion in the direction away from or close to the mounting rods, the effect of adjusting the sizes of vent holes can be achieved, the flow speed of the hot air flow can be controlled, and therefore the drying degree of the hot air flow on the dry-mixed mortar production raw materials can be controlled so as to enhance the drying effect.

Description

technical field [0001] The invention relates to the field of dry-mixed mortar, in particular to a drying and screening treatment system for raw materials for dry-mixed mortar production. Background technique [0002] Dry-mixed mortar (also known as dry powder mortar in the early days) is usually called hydraulic cement mixed mortar, which refers to aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened. A granular or powdery material that is physically mixed in a certain proportion and transported to the construction site in bags or in bulk. It can be used directly after adding water and mixing. It is also called mortar dry powder, dry mix, Dry mix powder, some construction adhesives also belong to this category. Dry mix mortar has a wide range of applications, but the production process of dry mix mortar is very complicated. Before making dry mix mortar, it is necessary to check ...

Problems solved by technology

[0002] Dry-mixed mortar (also known as dry powder mortar in the early days) is usually called hydraulic cement mixed mortar, which refers to aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened. A granular or powdery material that is physically mixed in a certain proportion and transported to the construction site in bags or in bulk. It can be used directly after adding water and mixing. It is also called mortar dry powder, dry mix, Dry mix powder, some construction adhesives also belong to this category. Dry mix mortar has a wide range of applications, but the production process of dry mix mortar is very complicated. Before making dry mix mortar, it is necessary to check the production of dry mix mortar. The raw materials are dried and screened so that the produced dry-mixed mortar meets the quality requirements. The following problems often arise:

[0003] 1. During the drying process, the falling speed of the screened production raw materials is too fast, the raw materials cannot be fully dried, and the drying degree of the dry-mixed mortar production raw materials cannot be controlled, so that the drying effect of the raw materials is not good. good;

[0004] 2. The existing drying and screening system only dries the raw material of the dry-mixed mortar once, which easily leads to insufficient drying of the raw material, and when the dried raw material is collected and dried again, the raw material is easy to pile up and Resulting in insufficient aggregate and very slow drying
