Description
Technical field
The utility model relates to material and adds technical field, more particularly refers to a kind of novel concrete grinding aid automatic feeding Controlling System.
Background technology
Cement grinding aid is a kind of chemical additive added in cement clinker milling process, can significantly improve cement unit-hour output, each length of time strength of cement, improve its mobility and mill efficiency.Because manufacture of cement is a successive processes, therefore the input of cement grinding aid also needs to carry out continuously.Existing cement mill generally adopts peristaltic pump or other conventional pumps when adding grinding aid, peristaltic pump is in adding procedure, and the grinding aid dosage added during the frequent variations of which particularly cement material is difficult to accurate control, thus affect production efficiency and the quality of cement.
For solving the problem, Authorization Notice No. CN202131227U Chinese utility model patent discloses a kind of grinding aid adding equipment, comprise grinding aid storage barrel, connect the pipeline between grinding aid bucket and grinding machine and be arranged on ducted volume pump, this adding equipment also comprises a PC controller, in pipeline between volume pump and bistrique, electronic grout flow meter is housed, PC controller connects electronic grout flow meter by data line, connects frequency transformer and volume pump successively again by data line.This grinding aid adding equipment opens volume pump by PC controller, electronic grout flow meter detects grinding aid flow and feeds back to PC controller by data line simultaneously, PC controller calculates a suitable frequency according to the data that electronic grout flow meter feeds back, and issue volume pump by frequency transformer, the rotating speed of volume pump is performed according to new frequency, and so circulation is till grinding aid flow accurately.But, this grinding aid adding equipment not only complex structure, cost is high, and PC controller needs to adjust volume pump rotating speed at any time according to electronic grout flow meter, not only flow chart loaded down with trivial details, time-consuming expense can, and electronic measurement easily occurs to detect the situations such as mistake or data transfer delay, thus affect the input ratio of grinding aid.
Summary of the invention
The utility model provides a kind of novel concrete grinding aid automatic feeding Controlling System, to solve existing cement grinding aid dispensing device complex structure, cost is high, flow chart is loaded down with trivial details, time-consuming takes can, and easily because detecting mistake or data delay, to cause grinding aid to throw in out of proportion.
The utility model adopts following technical scheme:
A kind of novel concrete grinding aid automatic feeding Controlling System, comprise cement mill, DCS Controlling System, indicating system, signal conversion module, toothed gear pump and cement grinding aid storage tank, described DCS Controlling System is connected with described cement mill, indicating system, signal conversion module and toothed gear pump respectively, described signal conversion module is connected with described toothed gear pump, and described toothed gear pump is connected with described cement mill and cement grinding aid storage tank respectively.
Further, above-mentioned signal conversion module is current transducer, and the range of current output of described current transducer is 4-20mA or voltage output range is 1-5VDC.
Further, the opening for feed of said gear pump is connected with above-mentioned cement grinding aid storage tank and cement mill respectively by rapid-acting coupling with discharge port.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
A kind of novel concrete grinding aid of the utility model automatic feeding Controlling System, DCS Controlling System calculates required cement dosage according to the cement material dosage in cement mill, and directly transmission current signal sends to toothed gear pump, toothed gear pump controls self according to current signal and rotates, and is added in cement mill by the cement grinding aid in cement grinding aid storage tank.Wherein toothed gear pump is often gone around, the amount that cement grinding aid discharged by toothed gear pump is the same, along with toothed gear pump constantly rotates, cement grinding aid constantly adds in cement mill, and the dosage of cement grinding aid directly controls by the rotation number of turns of toothed gear pump and speed of rotation.DCS Controlling System passes through the rotation number of turns and the speed of rotation of pinion pump, or fed back to the signal of DCS Controlling System by current transducer according to toothed gear pump, the quantity of the cement grinding aid added can be calculated in time and also need the quantity of the cement grinding aids added, and can be as the case may be, the rotation number of turns of pinion pump and speed of rotation at any time, thus reach adding of adjustment cement grinding aid in time.Compared with prior art, not only avoid setting up detection mistake or data transfer delay that electronic grout flow meter brings, make the utility model structure simple, flow chart is easy, cost is low, and adds in process at control cement grinding aid, has stronger processing speed and controllability, accurately adding of cement grinding aid be can momentarily control, the quality of production and the quantity of cement further improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The embodiment of the utility model embodiment is described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of novel concrete grinding aid automatic feeding Controlling System, comprises cement mill 1, DCS Controlling System 2, indicating system 3, current transducer 4, toothed gear pump 5 and cement grinding aid storage tank 6.Cement mill 1 is connected with DCS Controlling System 2, for being fed back in DCS Controlling System 2 by the cement material dosage in cement mill 1.
Be connected with indicating system 3, current transducer 4 and toothed gear pump 5 respectively with reference to Fig. 1, DCS Controlling System 2, current transducer 4 is connected with toothed gear pump 5.DCS Controlling System 2 exports the current signal of 4-20mA or the voltage signal of 1-5VDC directly to toothed gear pump 5, and toothed gear pump 5 receives this current signal or voltage signal, and adjusts the rotation number of turns and the speed of rotation of toothed gear pump 5 according to this signal.Meanwhile, toothed gear pump 5 sends feedback information by current transducer 4 to DCS Controlling System 2.Indicating system 3 for by information feed back such as cement material dosage, cement grinding aid dosage, toothed gear pump 5 rotational case in DCS Controlling System 2 to staff.
