Technical field
The present invention relates to a kind of mixing plant material weighing device, particularly relate to a kind of material difference meausring apparatus for filling mine workplace fill paste batching mixing plant, belong to paste body filling slip stirring technique field, be applicable to the weighing of the length of filling in mine exploitation apart from material to be stirred in Paste-filling System.
Background technology
China is the coal production of maximum in the world and the big country of consumption, along with the raising of technology level, in order to liberate " three times ", presses coal, and the filling technique in colliery has obtained great development.But fill paste requires each material proportion precision higher, and Weighing system needs long-time steady operation.One of difficult point that material weighing technology to be stirred is the paste body filling technology, the current main mode adopted is that material weighing and visual inspection stirring material are dense thick, finds when the stirring material is thicker to add in right amount water, otherwise adds aggregate.
Current common material weighing, for example, a kind of meausring apparatus that the utility model patent that number of patent application is 200920290028.8 provides, for with artificial visual inspection or adopt separately the open loop Weighing system of weightometer, and weighing simultaneously, precision is poor, be difficult to adapt to the accuracy requirement of mixing plant to material weighing, and repeatedly continuously add aggregate or water will extend mixing time, labor intensive, increase cost, delay production, can cause follow-up pumping when serious, filling, the link such as solidifying interrupts, pipeline jam accident or slip occur can not normal freezing, thereby bring the tremendous economic loss to enterprise.
Summary of the invention
Purpose of the present invention just is to overcome the prior art above shortcomings, provides a kind of material difference meausring apparatus based on filling.The inner parameter that the present invention is based on filling is the adjust automatic weighing of type material to be stirred of difference automatically, have simple in structure, reliability is high, according to user's demand can control that weighing, the precision of material in a plurality of material bins is high, stability is strong simultaneously, the characteristics of unmanned independent operating, remote monitoring for a long time, be particularly suitable for the weighing of Paste-filling System material to be stirred.
The technical scheme that the present invention provides is: this material difference meausring apparatus based on filling; include that scale hooper, sensor, material claim, the PLC(programmable logic controller (PLC)), touch-screen, electrically operated valve, be characterized in being arranged on sensor on scale hooper and the quality of material signal is transferred to material claims; Material claims by communication line and PLC(programmable logic controller (PLC)) be connected and transfer data to the PLC(programmable logic controller (PLC)), the PLC(programmable logic controller (PLC)) gather the data that material claims and accept from the setting data of touch-screen and by both substitution control programs the PLC(programmable logic controller (PLC)) be connected with electrically operated valve on being arranged on scale hooper by communication line and control the break-make of electrically operated valve.
For realizing better purpose of the present invention, the PLC(programmable logic controller (PLC)) in control program following steps are arranged.
The default weighing value that each needs of step 1., by its input PLC programmable logic controller (PLC).
The weighing value that when preset value of step 2.PLC programmable logic controller (PLC) internal condition input is determined valve closes, material claims, close threshold values.
Whether step 5.PLC programmable logic controller (PLC) detects in scale hooper quality of material and reaches and close threshold values: close threshold values if reach, carry out the next step valve-off; Do not close threshold values if reach, turn back to step 3 and open valve blowing again.
The step 7.PLC programmable logic controller (PLC) final weighing value of sampling.
Step 8. compares final weighing value and preset value, the correction error that must make new advances, and determine that thus the new threshold values that closes turns back in step 2 for next weighing.
In order to realize the reliability service of this Weighing system, control section should be placed on indoor.
Compared with prior art, the invention has the beneficial effects as follows: for Paste-filling System of Coal Mine mixing plant work characteristics, realized the automatic weighing of getting the raw materials ready, reduced to greatest extent the impact of human factor, saved cost of labor, reach control weighing error 1% with operation interior and steady in a long-term.
