Airflow impact type yellow sand screening and drying device

Abstract

The invention discloses an airflow impact type yellow sand screening and drying device. The airflow impact type yellow sand screening and drying device comprises a shell, a circulating air pump, an air outlet corrugated pipe, a filtering box body and an air inlet corrugated pipe, wherein an upper cover, a feeding hole, a sliding baffle plate, a right air connecting port, a left air connecting portand a discharging port are arranged on the shell; a vertical rod, a circulating air pump, an air outlet corrugated pipe, a filtering box body and a connecting air pipe are arranged at the lower end of the shell; a movable cover, an electric heating wire and an air inlet corrugated pipe are arranged on the filtering box body; the tail end of the air outlet corrugated pipe and the tail end of the air inlet corrugated pipe are provided with threaded joints; and lining plates, rotating shafts, supporting frames, bottom plates and supporting sleeves are arranged on the two sides of the shell. Thethreaded joints of the tail end of the air outlet corrugated pipe and the tail end of the air inlet corrugated pipe are matched with the left air connecting port and the right air connecting port, sothat the materials can be promoted to pass through and dust is synchronously removed under the action of the circulating air pump, and impurities can be recycled after the screening is completed, so that the device is convenient and efficient to use, and can improve the machining efficiency.

Description

technical field [0001] The invention relates to a building material screening device, in particular to an airflow impact type yellow sand screening and drying device. Background technique [0002] With the rapid development of urbanization today, all kinds of buildings, roads, bridges and supporting facilities are being constructed in an all-round way. Under this background, the demand for building materials is also increasing. Yellow sand is generally called sand, sand, gravel, etc. The composition of yellow sand is silica, which is widely used in the construction field. Most of the yellow sand is salvaged from the river, and impurities will inevitably enter during the transportation process. When used, it is often necessary to screen and remove the sand and impurities in the use of cement, which is also an important process in construction. [0003] The existing yellow sand screening is mostly manual screening with relatively low efficiency, while ordinary mechanical scre...

Problems solved by technology

[0003] The existing yellow sand screening is mostly manual screening, and the efficiency is relatively low, while ordinary mechanical screening has poor sustainability, and the accumulation of impurities generated during screening will affect the passing efficiency of subsequent materials
