Abstract
The utility model belongs to a road surface engineering machinery, relating to an additive agent weighing system of concrete mixing device. The system comprises an additive agent tank, a gravimetric tank and a material delivery pump arranged in a material delivery pipe line between the additive agent tank and the gravimetric tank. A solenoid valve is arranged at the material inlet at the top of the gravimetric tank. The utility model improves the measuring accuracy of the additive agent weighing system.
Description
Technical field
The utility model belongs to field of road engineering machinery, relates to a kind of additive weighing system of concrete batch plant.
Background technology
The additive weighing system of existing concrete mixing plant generally comprises an additive tank and a gravimetric tank that is connected with additive tank by transfer pipeline, and conveying pipeline is provided with dehvery pump in the road.During system works, pump is squeezed into gravimetric tank with additive, and when the weight of gravimetric tank reached setting value, electrical control system was sent instruction, the dehvery pump feed that stops the rotation.But after dehvery pump stopped the rotation, the possible all or part of inflow gravimetric tank of the additive in the pipeline of gravimetric tank top caused the metering inaccuracy.Even a bit close the power supply of pump in advance, after also being difficult to guarantee that each pump quits work, the material weight that the additive in the material loading pipeline flows into gravimetric tank is identical.Especially when additive amount had only 3～4Kg, relative error was bigger, may reach sometimes ± 5%, well beyond standard-required ± 1%.
Summary of the invention
Technical problem to be solved in the utility model is, the existing system structure is improved, and the additive weighing system of the higher concrete batch plant of a kind of measuring accuracy is provided
The additive weighing system of concrete batch plant of the present utility model includes additive tank, gravimetric tank and is arranged on dehvery pump in the conveying pipeline road between the two, is provided with an electromagnetic valve at the charging aperture place at gravimetric tank top.
The utility model is provided with at the charging aperture place of gravimetric tank can be by the electromagnetic valve of defeated material control system control, electromagnetic valve is opened when weighing, when the weight of gravimetric tank reaches setting value, electrical control system is sent instruction, close electromagnetic valve and the rotation that stops pump, stop to no longer include in the material loading pipeline behind the feed additive and flow into gravimetric tank, make each overshoot substantially constant, thereby improved measuring accuracy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the additive weighing system of this concrete batch plant comprises additive tank 1, gravimetric tank 2 and is arranged on dehvery pump 3 in the conveying pipeline road between the two, is provided with an electromagnetic valve 4 at the charging aperture place at gravimetric tank top.
