Abstract

The utility model discloses a high-accuracy compound production system for a concrete admixture water aqua. The high-accuracy compound production system comprises a plurality of material storage tanks, a mixing cylinder, multiple sections of connecting tubes, a plurality of proportional valves, a plurality of proportional valve electrical systems, a plurality of mass flow controllers, a plurality of timing counters, and a central controller, wherein each section of connecting tube is used for sequentially connecting one of the material storage tanks, one of the proportional valves and one of the mass flow controllers to the mixing cylinder; the timing counters are electrically connected with the respective corresponding proportional valve electrical systems; each of the proportional valves has at least three states, namely a first flow state, a second flow state and a closed state specifically; the central controller is used for receiving counted values of the timing counters, so as to control the switchover of the corresponding proportional valves from the first flow state to the second flow state; the central controller is used for receiving values of the mass flow controllers, so as to control the switchover of the corresponding proportional valves to be at the closed state. The system is high in compounding accuracy.

Description

The composite production system of a kind of concrete admixture aqua high accuracy

Technical field

It is composite that the utility model relates to a kind of concrete admixture aqua, is specifically related to the composite production system of a kind of concrete admixture aqua high accuracy.

Background technology

In present concrete, use the situation of single variety additive more rare, in order to meet the needs of concrete to various performances simultaneously, need to mix various additives composite, allow respectively be re-dubbed minute between acting in conjunction and produce the effect of stack, general composite additive is prepared by least two kinds of components, forms binary or polynary compound additive.

The composite production of concrete admixture aqua, adopt Artificial Control or operating personnel to adopt simple and mechanical production mostly at present, so will have following defect:

(1), additive of poor quality: because the manual work error is larger, make the deviation between ratio between each component of additive and formula larger, and then, make the difficult quality of the additive of preparation reach expection.

(2), the quality of additive is unstable: the gap between different operating personnel's professional skill, also there is any discrepancy for even same operating personnel's different time business level, and make the quality of additive unstable.

(3), manual work labour intensity is large.

The utility model content

The problem existed for prior art, the purpose of this utility model is to provide a kind of concrete admixture aqua high accuracy composite production system, and the composite precision of this production system is high.

The composite production system of a kind of concrete admixture aqua high accuracy that the utility model provides, it comprises a plurality of storage tanks, one a mixing bowl, the multistage tube connector, a plurality of proportioning valves, a plurality of proportioning valve electrical systems, a plurality of mass flow controllers, a plurality of timer conters and a central controller, wherein, every section described tube connector is successively by a described storage tank, one described proportioning valve and a described mass flow controller are connected to described a mixing bowl, described proportioning valve electrical system, described mass flow controller and described timer conter and described central controller are electrically connected, and described timer conter is corresponding and described proportioning valve electrical system is electrically connected, each described proportioning valve has at least three kinds of states and is specially the first flow state, the second flow status and closed condition, described central controller receives described timer conter count value, controlling corresponding described proportioning valve is switched to the second flow status by the first flow state, described central controller receives described mass flow controller numerical value, control corresponding described proportioning valve to closed condition.

Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:

In the composite production system of concrete admixture aqua high accuracy provided in the utility model, first flow and the second value of each described proportioning valve reasonably are set, can guarantee the uniformity in the feeding cycle of each described storage tank, thereby guarantee that each described storage tank feeding feeding each time is synchronous, in addition, each described proportioning valve has at least three kinds of running statuses and is specially the first flow state, the second flow status and closed condition, be that each described proportioning valve can arrange at least two kinds of different flows and carries liquid charging stock, thereby, each described proportioning valve can adopt large flow quick feeding and the accurate feeding of low discharge, and then, in large flow feeding guaranteed efficiency, low discharge is taken into account precision.
