Abstract

The invention provides a split vertical sand screening device for housing construction engineering. Through the split vertical sand screening device, the problems that in the river sand screening process of small and medium sized housing construction engineering, a horizontal rotary screen is large in occupied area and poor in applicability, and if screening frames are adopted for screening, the screening efficiency is low and the labor intensity is high are solved. The split vertical sand screening device comprises a fixed barrel and further comprises a rotary barrel, and the rotary barrel and the fixed barrel are connected rotationally and fixedly. The rotary barrel is in transmission connection with a motor. A spindle is arranged in the center of the rotary barrel. A discharging tank is arranged at an opening in the lower end of the rotary barrel. The upper end of the spindle is fixedly connected with a plurality of fixing columns. The upper ends of the fixing columns are fixedly connected with an upper cover. A first screening frame and a second screening frame are arranged below the upper cover sequentially from top to bottom, the first screening frame and the second screening frame are fixedly provided with screens of a conical structure so that a second screening zone and a third screening zone can be formed. A guide hood of a conical structure is arranged between a first screening zone and the second screening zone. A regulating rod is arranged between the guide hood and the upper cover. According to the split vertical sand screening device for housing construction engineering, the structure is compact, and the occupied area can be greatly reduced by means of the vertical structure.

Description

Firmly build engineering and separate vertical Sand screen

Technical field

The present invention relates to the engineering vertical Sand screen of separation is firmly built in sand screening field, more particularly to one kind.

Background technology

Need in engineering river sand to be used in a large number as concrete material firmly building, for ensureing the pouring quality of concrete, river Impurity in sand is not required to carry out strict control, because river sand is extracting and during depositing because the duration is permanent and river silt The reason, inevitably doped with debris such as clod, mortar stone, stone, plastics in river sand, so carrying out concrete proportioning Front river sand must be carried out with careful filtration to obtain pure river sand.

Complete the screening of river sand in heavy construction construction using drum-type classifying screen, but its volume of drum-type classifying screen is relatively Big installation moves very inconvenience, is typically all disposed within the stock ground constructed, transports construction more now after stock ground completes screening , such mode is very applicable for large-scale construction engineering, but arranges special for small and medium construction engineering Stock ground be not to be suitable for completely, the larger rotary screen of volume using cannot be suitable at all, builder one in this case As arrange a mesh screen being obliquely installed, then ceaselessly river sand to be screened is shed to mesh screen, is tumbled on mesh screen using river sand Process realize screening to river sand, obtain the pure river sand after mesh screen, the place that this screening mode needs is less, if Standby relatively simple, but its work efficiency is relatively low and needs to expend substantial amounts of muscle power.

Content of the invention
