Coarse aggregate separating device for cement concrete uniformity test

Abstract

The invention provides a coarse aggregate separating device for a cement concrete uniformity test. A hopper is installed at one end of a screening box installed aslant, a slant screening net is installed at the bottom of the screening box, and a clear water spray nozzle and a muddy water spray nozzle are arranged at one end, close to one end of the hopper, in the screening box; a pumping box is arranged at the bottom of the screening box; a horizontal screening net is arranged at the bottom of the pumping box, and a pumping box supporting frame is supported by supporting columns with absorption springs; a muddy water box is arranged below the pumping box, a clear water box independent from the muddy water box is installed in the muddy water box, and immersible pumps are installed in the muddy water box and the muddy water box respectively. The coarse aggregate separating device can be used for washing and screening coarse aggregates in fresh cement concrete, screening wasted cement concrete and recycling the coarse aggregates. Mixtures can be cleaned through clear water and muddy water at the same time, and therefore water resource utilization ratio is high.

Description

technical field [0001] The invention belongs to the field of cement concrete homogeneity test, and relates to a separation device, in particular to a coarse aggregate separation device for cement concrete homogeneity test. Background technique [0002] With the rapid development of industries such as construction, transportation and industry, cement concrete has become one of the most widely used and basic raw materials. The quality control of cement concrete in the application process consists of pouring quality and curing quality. Reasons for unqualified concrete include: unqualified raw material quality, unqualified admixture quality or inaccurate addition, mix ratio does not meet the requirements, and concrete is not poured in time. Therefore, it is of great significance in the industry to test whether the concrete is qualified. At the same time, the recycling rate of waste cement concrete in my country is very low, mainly because there is no standardized separation me...

Problems solved by technology

[0004] Aiming at the current lack of testing equipment for the uniformity test of cement concrete and the low recycling rate of concrete aggregates, the purpose of the present invention is to provide a coarse aggregate separation device for the homogeneity test of cement concrete, which can not only screen The coarse aggregate of freshly mixed cement concrete can be produced, and at the same time, the waste concrete coarse aggregate that cannot be used in the experiment or construction can be screened and utilized
