Description

Technical Field

[0001] The utility model relates to the technical field of mortar raw material screening, in particular to mortar raw material drying and screening equipment. Background Art

[0002] With the rapid development of the construction industry, the demand for mortar, as one of the important building materials, has increased year by year. Mortar raw materials often contain a certain amount of moisture and impurities during the production process, which directly affects the quality and performance of the mortar. It is particularly important to dry and screen the mortar raw materials.

[0003] For example, a mortar raw material screening equipment (Announcement No.: CN217726207U) allows hot air to enter the inner side of the screening cylinder through the air inlet, and cooperates with the roller to drive the scraper to rotate the mortar raw materials, so that the mortar raw materials can be evenly heated in the screening cylinder, and the dried mortar raw materials are in contact with the inner wall of the screening cylinder along with the scraper, so that the mortar raw materials can pass through the bottom of the screening cylinder and enter the top surface of the vibrating screen. The guide plates at both ends of the vibrating screen are inclined, which facilitates the concentration of the mortar raw materials on the top surface of the vibrating screen, and can screen mortar raw materials of the same size into the collecting hopper, while large particles of debris are scattered on the surface of the vibrating screen. The vibrating screen can be removed from between the clamping plates by loosening the bolts for cleaning, thereby achieving the effect of easy disassembly and assembly.

[0004] However, the device still has the following defects:

[0005] When the device is in use, it can only perform single-stage screening on the mortar raw materials. Single-stage screening cannot adapt to the production of mortar with different particle size requirements. As market demand changes, the particle size requirements for mortar may also be adjusted. If the equipment can only perform single-stage screening, then when faced with different particle size requirements, it may be necessary to replace or adjust the equipment, which increases production costs and operational complexity. Therefore, we need to propose a mortar raw material drying and screening equipment. Utility Model Content
