Dust-free concrete aggregate batching device

Abstract

The invention discloses a dust-free concrete aggregate batching device.The dust-free concrete aggregate batching device comprises a fixed base and an aggregate storage tank arranged over the fixed base, the fixed base is provided with a weighing device located under the aggregate storage tank, and an aggregate receiving box is arranged over the weighing device; the top of the aggregate receiving box is provided with an aggregate receiving pipe pointing to the aggregate storage tank, the bottom of the aggregate storage tank is provided with a discharge pipe extending into the aggregate receiving pipe, and a dustproof ring is arranged between the outer circle of the discharge pipe and the inner wall of the aggregate receiving pipe.According to the dust-free concrete aggregate batching device, the dustproof ring can prevent dust from being generated at the joint of the discharge pipe and the aggregate receiving pipe and reduce the vibration influence of the discharge pipe on the aggregate receiving pipe, the working precision of the weighing device is improved, the device is beneficial for improving the concrete quality, operation is convenient, and use is flexible.

Description

technical field [0001] The invention relates to the field of concrete production, in particular to a dust-free batching device for concrete aggregate. Background technique [0002] Concrete is one of the most important building materials in the contemporary era. It is prepared in a certain proportion from cementitious materials, granular aggregates (also known as aggregates), water, and admixtures and admixtures added when necessary. After uniform mixing, A kind of artificial stone formed by dense molding and curing. [0003] Concrete has the characteristics of abundant raw materials, low price, and simple production process. At the same time, concrete also has the characteristics of high compressive strength and good durability, and is widely used. The proportion of raw materials in concrete is relatively strict, and it needs to be mixed according to the weight of each raw material in the formula. The proportion of cementitious material and water is relatively easy to cont...

AI Technical Summary

Problems solved by technology

The proportion of raw materials in concrete is relatively strict, and it needs to be mixed according to the weight of each raw material in the formula. The proportion of cementitious material and water is relatively easy to control, and the aggregate is an irregular particle, which is difficult to carry out during the batching process. Accurate weighing can easily lead to the failure of concrete indicators, and it is easy to generate dust during the batching process, which needs to be improved
