Abstract

The invention provides a precoated sand air classification machine which is simple in structure, good in air classification efficiency, little in energy consumption and environmentally friendly, and saves energy. The precoated sand air classification machine comprises a shell, and is characterized in that the side wall of the shell is provided with an air vent and an air outlet correspondingly, a baffle is arranged inside the upper portion of the shell aslant, a sand outlet defined by the baffle is horizontally provided with a guide board facing the air vent, at least one separation device is arranged below the sand outlet, an air inlet is correspondingly formed in one side of the separation device and located in the side wall of the shell, the separation device comprises an inclined board and a separation board, the separation board is correspondingly arranged below the sand outlet, and a sand falling hopper and a dust falling hopper are arranged below the separation device.

Description

technical field [0001] The invention relates to sand processing equipment in the foundry industry, in particular to a wind separator for coated sand. Background technique [0002] In the production of coated sand, air separators are widely used to separate sand and dust. Air separators are based on the principle of aerodynamics, which use air as the sorting medium, and under the action of air flow, the membrane sand is classified according to density and particle size. Sorting by size to separate the dust or impurities in the coated sand from the sand to complete the purpose of screening. [0003] Some existing coated sand winnowing machines usually use negative pressure winnowing machines, which have complex mechanisms, high energy consumption, and small winnowing force, which results in poor winnowing effect and affects the quality of sand. Contents of the invention [0004] In view of the above problems, the present invention provides a coated sand winnowing machine, w...
