Description

Technical Field

[0001] The utility model relates to the technical field of mortar production and processing equipment, in particular to a drum screen used for removing impurities from mortar. Background Art

[0002] In the construction industry, mortar is an important raw material in construction. Specifically, mortar is an adhesive material used for bricklaying in buildings. It is made of a certain proportion of sand and binder materials and water. It is also called mortar or sand mortar. Common mortars include cement mortar, mixed mortar, lime mortar and clay mortar. During the mortar mixing production and processing, a screening structure is required to screen the raw materials. The screening structure of the prior art is mostly composed of a base and a bracket, and there is a corresponding screening net on the bracket. Not only is the structure bulky and not easy to move, but it is also prone to clogging and is not conducive to cleaning and maintenance. Therefore, its applicability and practicality are limited, and it is difficult to meet market demand;

[0003] For example, the Chinese utility model patent with authorization announcement number CN213971864U discloses a dry mortar mixing device that is easy to disassemble, assemble and clean. However, it lacks a structure for screening and filtering the mortar, so that the device can only stir the mortar but cannot screen the solid impurities in the mortar. As a result, the processed mortar contains more other impurities, which affects the processing quality of the mortar.

[0004] Therefore, we propose a drum screen for removing impurities from mortar in order to solve the above problems. Utility Model Content
