Abstract
The utility model discloses a liquid weighing device is used at stirring station, including the scale hooper, set up and go into the unhurried current groove of pipeline intercommunication in scale hooper top and pump for the weighing sensor of scale batch box weight, the unhurried current is connected with on the groove respectively to the thick gauge line and thin gauge line of scale hooper blowing, installs the stop valve on the thin gauge line, the fluid passage pump is gone into the pipeline and is got into the unhurried current groove, gives the scale hooper feed by thick gauge line when begin to measure, stops the feed 90% o'clock when the feed demand, open the stop valve and pass through thin gauge line feed, until reaching the demand 100%. Because the thick gauge line of thin gauge line is thinner, the liquid stream in the thin gauge line is steerable, has both reduced the shock effect of liquid stream symmetric body, has guaranteed the measuring accuracy of liquid again, can carry out precise measurement according to the required liquid that the concrete match ratio required.
Description
Technical field
The utility model relates to a kind of device for adding liquid accurate in mixing plant, is specifically related to a kind of mixing plant liquid meausring apparatus.
Background technology
In concrete batch plant, water and liquid additive have a significant impact concrete finished product, particularly liquid additive, and amount but affects huge less.The metering method of current concrete mixing plant to liquid has two kinds: volumetric metering and weight-type metering.Positive displacement many employings liquid level gauge is measured liquid level, and weight-type is then utilize electronic scale directly to weigh adjuvant.Because the weighing precision of liquid level gauge is lower, weight-type metering is divided into again two kinds of forms, directly weighs and indirectly weighs.Direct weighing weighs also known as method of addition, namely need how many how much weighing, but this weighing mode can produce impact to electronic scale when liquid falls, and affect the final weighing precision of additive.Indirect weighing weighs also known as Subtraction method, namely weighs more additive liquid in advance at scale hooper, and then according to match ratio aequum, after deducting pumping by current weighing value, weighing value gained is exactly aequum.Greatly can reduce the error because hydraulic shock causes like this.But this weighing technique always produces residue after hours each in scale hooper, the necessary process in time of rest additive, otherwise easily cause the corrosion of waste or symmetrical batch box.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mixing plant liquid meausring apparatus, ensures the degree of accuracy weighed, improves the production quality of cement concrete.
For achieving the above object, the utility model by the following technical solutions:
A kind of mixing plant liquid meausring apparatus, comprises scale hooper, be arranged on above scale hooper with the unhurried current groove pumping into pipeline communication, for the LOAD CELLS of weighing balance batch box weight; Unhurried current groove is connected with the thick gauge line respectively to scale hooper blowing and thin gauge line, thin gauge line is provided with intercepting valve.
Further, described scale hooper is cylindrical shape, and three LOAD CELLS are 120 ° of layouts around scale hooper.
Further, described LOAD CELLS is pressure transducer or pulling force sensor.
Further, be connected with discharge nozzle bottom described scale hooper, discharge nozzle is provided with pneumatic control valve.
Further, described LOAD CELLS is pressure transducer or the pulling force sensor of 500 kilograms.
The utility model has the advantage of:
(1) current concrete mixing plant liquid meter scale is transformed, add the equipment such as LOAD CELLS and thin gauge line, liquid enters unhurried current groove by pumping into pipeline, when starting to measure by thick gauge line to scale hooper feed, feed is stopped when feed aequum 90%, open intercepting valve by thin gauge line feed, until reach 100% of aequum.Because the thicker gauge line of thin gauge line is thinner, the liquid stream in thin gauge line can control, and has both reduced the impact impact of liquid stream symmetric body, in turn ensure that the measuring accuracy of liquid, and needed for can requiring according to concrete mix, liquid carries out accurate measurement.
(2) the utility model is reasonable in design, structure is simple, it is simple and easy to operate, systematization, function are many, good stability, degree of accuracy advantages of higher, can be applicable to the various concrete mixing plants of different regions, Based Intelligent Control can be realized, promote mixing plant automaticity, reduce personnel depaly and resource distribution, thus save production cost, improve production efficiency greatly, ensure that the solidifying concrete quality of production.
Accompanying drawing explanation
Fig. 1 is the structural representation arranging pressure transducer of the present utility model;
Fig. 2 is the structural representation arranging pulling force sensor of the present utility model;
Wherein: 1-flows slowly groove; The thick gauge line of 2-; 31-pressure transducer; 32-pulling force sensor; 4-scale hooper; 5-pneumatic control valve; The thin gauge line of 6-; 7-intercepting valve; 8-pumps into pipeline.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to these embodiments.
As shown in Figure 1, the utility model comprises pressure transducer 31 and a charging gear composition of a scale hooper 4, three 500 kilograms, charging gear comprise be arranged on above scale hooper 4 with pump into the unhurried current groove 1 that pipeline 8 is communicated with, thick gauge line 2 and thin gauge line 6, thin gauge line 6 is provided with intercepting valve 7, by charging gear to scale hooper 4 blowing, scale hooper 4 is provided with the LOAD CELLS for weighing balance batch box 4 weight.
Liquid is by pumping into pipeline 8 through unhurried current groove 1, and when starting to measure, intercepting valve 7 cuts out, and first gives scale hooper 4 feed by thick gauge line, feed is stopped when feed aequum 90%, open intercepting valve 7, allow the liquid flow slowly in groove 1 by thin gauge line feed, until reach 100% of aequum.Because the thicker gauge line of thin gauge line is thinner, the liquid stream in thin gauge line can control, and so both reduces the impact impact of liquid stream symmetric body, in turn ensure that the measuring accuracy of liquid.
Further, scale hooper 4 is cylindrical shape, weight sensor is pressure transducer 31, three pressure transducers 31 are evenly distributed on circular scale hooper in 120 °, because 3 are determined a plane, both avoided arranged that single-sensor weighing scale causes in the past swing or arrange the unbalance loading that two sensor weighing scales cause all around, make it steady, without rocking, adding the reliability of weighing, further increasing the degree of accuracy that liquid weighs.
Further, be connected with discharge nozzle, discharge nozzle be provided with pneumatic control valve 5 bottom described scale hooper 4, LOAD CELLS is the pressure transducer 31 of 500 kilograms.
As shown in Figure 2, weight sensor is pressure transducer 31, and three pulling force sensors 32 are evenly distributed on circular scale hooper in 120 °.
The utility model selects increment scale to carry out the metering of liquid, but will carry out certain improvement to metering system, arranges thick, tubule combination control method and to adopt three sensor element to eliminate the metering caused by unbalance loading inaccurate.This will improve the production quality of cement concrete greatly, significantly enhance productivity, have wide popularizing application prospect.
