Combined building sand filtering and dust removal device

Abstract

The invention discloses a combined screening and dedusting device for building yellow sand, which comprises a housing, a circulating air pump, an exhaust hose, a filter box and an intake hose, and the housing is provided with an upper cover and a feeding hopper , material guide plate, sieve plate, right air port, left air port and discharge port; the lower end of the shell is provided with a threaded column, a rotating placement plate, a circulating air pump, an exhaust hose, a filter box and a connecting air pipe; the filter box There are movable upper cover, filter cloth plate and intake hose on the top; threaded joints are provided at the end of the exhaust hose and intake hose; fixed plates, rotating shafts, support frames, bottom plates, and swing screw rods are installed on both sides of the housing , Counterweight slider and fastening bolts. The invention cooperates with the threaded joint at the end of the exhaust hose and the intake hose, and the left air port and the right air port, which can promote the passage of materials and synchronously remove dust under the action of the circulating air pump. Impurities can also be recovered after the screening is completed. , easy to use and efficient, can improve processing efficiency.

Description

technical field [0001] The invention relates to a building material screening device, in particular to a combined screening and dust removal device for building yellow sand. 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 mechanic...

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
