Device for fast filtering impurities from gravel and stone for constructional engineering

Abstract

The invention discloses a device for fast filtering impurities from gravel and stone for constructional engineering. The Device for fast filtering impurities from gravel and stone for constructional engineering comprises a gravel and stone filtering box body, wherein a feeding opening is formed in the upper end of the gravel and stone filtering box body; a dust adsorption mechanism is arranged atone side of the gravel and stone filtering box body; the gravel and stone filtering box body comprises a vibration motor, an air inlet pipe, dust suction pumps and a dust adsorption box; a composite efficient impurity filtering mechanism is arranged inside the gravel and stone filtering box body, and comprises a screening grid, a fine sawdust filtering net, an activated carbon adsorption layer anda filtering chamber; and a detachable cleaning mechanism is arranged at the lower end of the composite efficient impurity filtering mechanism, and comprises a sliding rod, a wrench, a fine dust adsorption net and an inserting pin. The device for fast filtering impurities from gravel and stone for constructional engineering has the advantages that the device is provided with a motor for adsorbingthe dust; the dust adsorption net can be dismounted to be cleaned; and the composite efficient impurity filtering removal is realized, and the like. Better use prospects are brought.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a sand and gravel quick filtering device for construction engineering. Background technique [0002] The most common building materials in construction projects are gravel and stones. Stones and gravel are usually mixed together before being screened. Filtering equipment is required to filter the sand and gravel before use. During the screening of sand and gravel, a large amount of dust and debris will appear, most of which are sawdust, grass roots, and tree roots. These impurities naturally exist between sand and gravel. Using sand and gravel containing these impurities to prepare concrete will reduce the strength of concrete. Due to the fact that the surface is relatively low and surface collection and scum appear during the sampling process, generally, filter equipment capable of screening is used to process sand and gravel. [0003] The existing sand and gra...

Problems solved by technology

[0003] The existing sand and gravel filter devices for construction projects have certain disadvantages when they are installed and used. The traditional filter equipment has low efficiency in absorbing dust and is not easy to replace, which leads to a decrease in the adsorption efficiency of the adsorption net and still affects the operator's safety. Physical health, the single function of the filter device, etc. have brought certain adverse effects on people's use process. Therefore, we propose a sand and gravel rapid filter device for construction projects.
