Abstract

A decremental proportioning technology for concrete is based on the principle ofelectric minus balance and features that multiple raw material hoppers and weighing hoppers are integrated and the weighing hopper sensors and relative decremental controller are used to quantitatively and sequentially decrease the weight of each material in time. Its advantage is high precision.

Description

A kind of concrete decrement proportioning process

Technical field

The present invention relates to a kind of concrete batching technology, especially relate to a kind of concrete decrement proportioning process.

Background technology

Concrete is one of most widely used material in the architectural engineering, its economic and technical norms have very important relation to the quality and the cost of whole architectural engineering, its waste product that is off quality, can not be as the substandard products or the use that downgrades, so concrete quality control in process of production is particularly important, though it is a lot of to influence the factor of concrete quality, the accurate feed proportioning in the production process is crucial.The most employings of available coagulation soil batching increase progressively reinforced mode and prepare burden, not only the time is long but also complicated operating process for this batching mode, its equipment adopts independently silo and scale hooper, complex structure, bulky, the manufacturing cost height, be unfavorable for transportation and on-the-spot the installation, only use at present in the bigger job site of scope of construction item, most of middle and small scale construction sites are still continued to use middle-size and small-size mixer, adopt the conventional method of human metering, be about to each material and use a pound weighing one by one, its inefficiency, weighing precision is poor, and intensity of workers is big, the concrete formulation precision is difficult to guarantee, stays the technology hidden danger that is difficult to overcome to job site management and construction quality.

Summary of the invention

The objective of the invention is in order to overcome the deficiencies in the prior art, is the concrete decrement proportioning process that adapts to middle-size and small-size scale job site and provide a kind of.

For achieving the above object, the technical solution used in the present invention is: a kind of concrete decrement proportioning process, it is characterized in that its utilization Electronic Negative scale principle, a plurality of silos and scale hooper are united two into one, by scale hooper sensor and the corresponding in time quantitative weight of proportioned material in proper order of decrement batching controller.

When needs are prepared burden, the scale hooper sensor will be thrown in weight of material and convert signal of telecommunication input decrement batching controller to, when a certain material injected volume reaches the proportioning value, the decrement batching controller will send instruction, stop the input of this material, and then the another kind of material of control input, the rest may be inferred, reaches the purpose of accurate measurement, automatic blending.

Advantage of the present invention is: technology of the present invention is simple, the measuring accuracy height, batching is accurate, and it is not only applicable to electronic batching machine, and be applicable to batching machines such as steam-operating, hydraulic pressure, can also be applied to the industries such as metallurgy, chemical industry, feed beyond the concrete batching simultaneously.
