Description

Technical Field

[0001] The utility model mainly relates to the technical field of mortar processing, and in particular to a vibrating screen for producing dry mortar. Background Art

[0002] Dry-mix mortar refers to a granular or powdered material that is physically mixed in a certain proportion with dried and screened aggregates, inorganic cementitious materials and additives. It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. It is widely used in the construction and decoration industries.

[0003] The production process of dry mortar requires the use of a vibrating screen for vibratory screening. Considering that dust may affect the health of operators, a vibrating screen is set inside the machine body for screening. For example, the patent authorization announcement No. CN202120551632.2 discloses a vibrating screening device for a dry mortar station, including a housing assembly, a drive assembly, an elastic support, an eccentric block, a scraping assembly and a screening net. The housing assembly includes a screening housing, and an inclination angle of 15-30 degrees is provided between the lower surface and the upper surface of the screening housing. An opening is provided on one side of the upper surface of the screening housing, and a feed hopper is provided at the upper end of the opening. A discharge port is provided at the lower end of the screening housing. A semicircular screening net is provided inside the screening housing, and a scraping assembly is provided inside the screening housing. Two eccentric blocks are provided on the scraping assembly, and a driving assembly for driving the scraping assembly to rotate is provided on the screening housing. An elastic support is provided on the screening housing, and the up and down vibration effect of the housing assembly is better through the connecting spring.

[0004] Although the vibrating screen reduces the use of motors, the semicircular screening mesh can only screen out two specifications of dry mortar during the screening process. The screening effect is limited, and the traditional screen is not easy to disassemble. On this basis, and in order to meet the diversified development of the market, a vibrating screen for dry mortar production is proposed. Utility Model Content
