Weighing as one of the present invention and join the further prioritization scheme of water control system, described power supply is two tunnel output direct-current switch power supplies, and wherein a road output is connected with electronic load cell and weighing-up wave amplifier respectively, and the output of another road is connected with the first potentiometer.
By two potentiometers, the conversion of weighing-up wave is implemented the control of the running frequency size to converter, then uses electric interlock, it is achieved synchronized to determine the size of amount of water by feeding quantity.Reach according to the requirement carrying out doses uniform water distribution.
Switching Power Supply in electric control module has two kinds of output voltages, Ye Jiao bis-tunnel, a road therein supplies weigh amplifier and electronic load cell work, it is made to convert the weight detected to d. c. voltage signal, an other road of Switching Power Supply is used for supplying the first potentiometer work, is used for balancing material conveyer belt or the deadweight of independent belt conveyer scale of weighing through changing of the first potentiometer.The voltage output end of the first potentiometer as the low-pressure end of the second potentiometer, is used simultaneously as a pole of the GND of the external command frequency signal of converter on the one hand.The high-pressure side of the second potentiometer accepts the positive pole of weighing-up wave, and the positive pole of the input of converter external command frequency signal received by outfan.It is achieved in that the running frequency of converter becomes certain proportionate relationship all the time with the instant cleaning liquid weight of material, the purpose just having reached dynamic tracking need not have been calculated.
The present invention adopts above technical scheme compared with prior art, has following technical effect that
1. need not data calculate, so being unworthy of the computers such as dedicated program single-chip microcomputer, PLC, but with an electric pressure converter, the gross weight signal weighed is deducted the deadweight signal of weigh belt conveyer scale or empty travelling belt, the DC signal with another electric pressure converter, the nt wt net weight signal of the material deadweight signal of conveyer belt (the gross weight signal deduct) converted to again carries out the appropriate regulation running frequency control signal as converter, with reach control the actual amount of water of water pump with the weight of clean material form corresponding proportion change, implement dynamic tracking；
2. device feature is few, simple to operate, and maintenance is little, few easy workout part, and attendant's competency profiling is not high, and common electrical, universal machine maintenance mans can implement maintenance under the telephone guidance of producer technical staff；
3. production cost is low, safeguards simple, and use cost is low, and reliability is high, and the life-span is long, has at a relatively high promotional value.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described in further detail:
As it is shown in figure 1, the invention discloses the water distribution control device of weighing that a kind of brick-tile industry uses, comprise Weighing module, electric control module and water supply module；
Wherein, Weighing module includes electronic load cell and weighing-up wave amplifier；
Electric control module includes power supply, the first potentiometer R1, the second potentiometer R2, converter；
Described power supply is connected with electronic load cell, weighing-up wave amplifier respectively, the low-pressure end of described first potentiometer R1, high-pressure side are connected with power supply, outfan is connected with the GND end of the low-pressure end of the second potentiometer R2, converter respectively, and the high-pressure side of described second potentiometer R2 is connected with the outfan of described weighing-up wave amplifier, outfan is connected with the input of converter external command frequency signal；
Water supply module includes water pump, and the motor of described water pump is connected with the lead-out terminal of described converter.
Weighing as one of the present invention and join the further prioritization scheme of water control system, described power supply is two tunnel output direct-current switch power supplies, and wherein a road output is connected with electronic load cell and weighing-up wave amplifier respectively, and the output of another road is connected with the first potentiometer R1.
This device utilizes the external command frequency signal of weighing-up wave and converter to be all the convenience of this same kind of analogue signal of direct current 0～10V, use 2 potentiometers (slide rheostat), i.e. the first potentiometer R1 and the second potentiometer R2, directly weighing-up wave is converted the operating frequency signal of converter to, it is achieved that need not calculate and just reach the instantaneous weight with principal goods material and follow the tracks of the purpose of water distribution in time.
Action that this device is the instantaneous weight according to principal goods material and whether reinforced actuating signal determine to synchronize to add water from dynamic control device, it is not necessary to staff on duty, union operation on the operating board of main post work can be arranged on for eletric starter button.Cabinet face is only provided with the display lamp HL1 that powers on, electromagnetic valve YV turns on display lamp HL2, the control of amount of water is provided basis signal by weighing-up wave, the command switch K whether added water is synchronized to determine (being also interlocking) by the reinforced action of principal goods material, separately set SA-2, it is simple to debugging and maintenance etc. actively cut off water route and converter work.The weight of principal goods material is obtained by the electronic load cell installed, and converts 0～10V direct current signal to then through signal amplifier.From deserving to be called the weight resultant signal that the weight signal obtained is subordinate mechanism and principal goods material, subordinate mechanism is generally belt conveyor.When equipment is not added with the idle running of principal goods material, we are called the deadweight of subordinate mechanism or tare weight, deserve to be called and still can be subject to certain power, can produce the output of corresponding voltage.The sliding point of the second potentiometer R2 is transferred to maximum value point by us, and the first potentiometer R1 is transferred to minimum resistance point, and now shown on the nixie display of converter frequency number becomes certain proportionate relationship with above-mentioned voltage.Indirectly know voltage in other words.And now require water pump not turn or amount of water is zero, a mounted subordinate mechanism weight of specifically weighing is basically unchanged.Now just can by regulate the first potentiometer R1 adjustable contact export a DC voltage balance this analog voltage, near equilibrium point, the show value of converter is about zero, when reaching dry run each several part work but do not add water.
In actual production, moisture time length that principal goods material self is contained also can change, each producer of the moisture content of production requirement is likely to and differs, this just requires that water addition ratio example is adjustable, the nt wt net weight signal of principal goods material is carried out certain proportion adjustment by the second potentiometer R2 by design, signal after adjustment controls the operating frequency of converter again, is always ensured that the operating frequency that adds water becomes certain proportionate relationship with principal goods material instant cleaning liquid weight signal, further reaches to control the purpose of suitable amount of water.
After converter powers on, element task program is opened.The on the one hand voltage signal of the external command operating frequency size between detection two points of AI1 and GND, after shown pre-operating frequency number by nixie display.Wait working signal (COM and FWD conducting) on the other hand.Being provided with SA-1 on this path and force on and off switch, another conveying arrangement with principal goods material implements electric interlock.
