Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for thermal insulation mortar. Background Art

[0002] The preparation of thermal insulation mortar requires sufficient mixing of various raw materials such as cement, granular materials, fillers, admixtures, etc., and ensuring the uniformity of mixing to improve the performance and construction quality of the thermal insulation mortar. The mixing device will mix these raw materials together in proportion. The mixing device can help ensure that the various components in the thermal insulation mortar are fully mixed to prevent lumps or uneven mixing. The existing technology solves the problem of a large amount of residual material in the mixed mortar discharge, but the mortar aggregate cannot be screened before the mixing process.

[0003] A Chinese patent discloses an insulation mortar mixing device (authorization announcement number CN219748469U). The patented technology includes a mounting platform, a plurality of support rods are fixedly installed at the bottom of the mounting platform, a mixing drum is arranged inside the mounting platform, and the mixing drum is fixedly installed on the top of the plurality of support rods; a stirring assembly, the stirring assembly is used to mix the insulation mortar inside the mixing drum; a pushing assembly, the pushing assembly can push the slurry inside the mixing drum to facilitate discharging. In the utility model, the raw materials of the insulation slurry are fully mixed to form a uniform insulation slurry, and the moving pushing plate can be driven to move while the stirring rod rotates, which can further stir the insulation slurry, and the insulation slurry attached to the inner wall of the mixing drum can be scraped off when discharging, which can improve the discharge rate of the insulation slurry.

[0004] This patented technology has the ability to improve the situation of low discharge rate when used, but it still has some shortcomings when used. Large-sized mortar aggregates affect the quality of the mortar after mixing, and thus the thermal insulation and crack resistance of the thermal insulation mortar are reduced. The mixing device cannot screen the mortar aggregates. Therefore, those skilled in the art provide a mixing device for thermal insulation mortar to solve the problems raised in the above background technology. Utility Model Content
