Chemicals dosing plant mainly includes frequency conversion screw conveyor 31, medicinal powder hopper 32 and meal outlet 33.Chemicals dosing plant is based on becoming
The working frequency of frequency screw conveyor and the linear relationship of dosage carry out dosing.Frequency conversion screw conveyor 31 uses frequency converter
Driving, after setting frequency, it is only necessary to control the on/off of converter plant, you can while realize the frequency conversion screw conveyor 31
With specific frequency start and stop.
In practical applications, it can further contemplate dry powder whether there is detection, dry powder attachment bucket wall and medicinal powder hopper
Because temperature and steam cause delivery port hardening to block at meal outlet, therefore can be asked by configuring all kinds of ancillary equipments with solving these
Topic, optimizes automated dispensing system.Ancillary equipment portion mainly includes auxiliary mixer 51, heater 52, shakes device 53 and material position is opened
Close 54.Ancillary equipment plays a crucial role the normal operation of system to strengthen the stability of dispensing system.
Auxiliary mixer 51 is completely dissolved in solution for secondary solvent.In embodiment, it is respectively provided with 1#, 2#, 3# case
There is an auxiliary mixer 51, three auxiliary mixers 51 in spite of making up a prescription because being required for being stirred continuously, to ensure that solvent fills
Divide and dissolve and place medicament deposition.
Heater 52 is arranged at meal outlet 33, heater 52 be that temperature is too low in order to prevent and a small amount of steam caused by
Dry powder solidification so that meal outlet 33 keep drying, prevent dry powder solidification attachment meal outlet.
Shake device 53 to be fixed on medicinal powder hopper 32, can prevent dry powder from largely adhering to bucket wall.Shaking device 53 had better not
Long-play, but discontinuity circular flow is used, can so prevent from shaking for a long time causes dry powder to be tamped, and can also solve
The problem of dry powder adheres to.The domestic DH48S-S types digital display loop control time relay can specifically be selected, it can be achieved that every 10 points
Clock acts the circular flow of 1 minute, and delay time and actuation time can be set, and sets scope 1S-99H.
Wherein, aid in mixer 51 and heater 52 to need long time running, full manual control mode can be taken, without connecing
Enter remote control or on the spot automatic control system.Frequency conversion screw conveyor 31, shake device 52, break-make solenoid valve 23 and access remotely
Control or on the spot automatic control system.
Material-level measure can interlock system.Specifically one level switch 54 can be set in hopper lower part, for dry powder
Material position is monitored, and detection dry powder whether there is, No starting dispensing system when without material, and sends the instruction of acousto-optic fault alarm
Unit, such as buzzer, LED light.
Two kinds of system control interfaces of offer of the dispensing system, can corresponding selection remote control and two kinds of controls of control on the spot
Pattern.Used by remote interface control and feed back liquor box liquid level analog value on the spot, and two position is judged by host computer, into
And give whole one contact point signal started or stoped of dispensing system；Detection switch instruction interface can use water tank inner float ball on the spot
Installation height liquid-level switch 42 on switch 41 or magnetic turning plate, signal is directly as system start and stop condition.Specific control connection side
Formula is as follows：
When remote control, the start and stop of the dispensing system provide a start stop signal dry contact by host computer and obtain start and stop
Signal.Signal type can take the presence or absence of long signal form, this signal can be by liquor box teletransmission to magnetic turning plate, then feed back to upper
Machine, host computer judge according to liquid level analog signals, with the start and stop of control system.
Control may be selected on the spot control manually or automatically control on the spot on the spot.According to manual control mode on the spot, each
Actuator is both needed to match somebody with somebody a set of start-stop button on the spot and state instruction；According to automatic control mode on the spot, it is necessary to by water tank
Height float switch accesses control logic, and the activation system when liquid level is low, when liquid level high RST occurs, that is, is automatically stopped pair
Frequency conversion screw conveyor, break-make solenoid valve, the use for shaking device etc..
Electric control box provide all electrical equipments and the control logic of detection device in automated dispensing system integrate with
And equipment function of supplying power, the electrical equipment involved in the system and detection device are had and logically connected, so as to reach
The purpose of system normal table operation.Electric control box includes being used for the start and stop instruction interface for connecting host computer, for being obtained from
The start stop signal (starting or stoping signal) of dynamic dispensing system.
Fig. 2 in shown in embodiment essentially describe all kinds of parts that the system is related to electrical connection circuit and
The parameter information of essential electrical component in each circuit；The control that Fig. 3 (a) essentially describes each electrical equipment in system is former
The information such as reason, interlock condition.
The course of work of automated dispensing system disclosed in the embodiment is as follows：
The first step, using suspended body flowmeter on the spot, hand-operated valve, break-make solenoid valve combination control flow of inlet water.
Specifically, adjusting flow of inlet water manually using hand-operated valve, feed water flow value is determined by suspended body flowmeter on the spot
Afterwards, break-make solenoid valve control flooding time of intaking, the access electrical control of this break-make solenoid valve are passed through.Break-make solenoid valve can use state
2W series Direct Action Type diaphragm electromagnetic valves are produced, its break-make is influenced by three conditions such as model selection, start and stop condition, hand push button, in detail
See Fig. 3 (a).
Second step, is conveyed by frequency conversion screw conveyor to control dosage.
In embodiment, dosing conveys the control for realizing dosing speed by way of frequency conversion screw.Because sewage disposal is led
Domain is smaller to the claimed range of the dry powder class drug concentration, and is in spot distribution, i.e., a set of water treatment system longtime running only has
3-5 kind drug concentrations, therefore the system can not set accurate plus powder medicine metering device, but targetedly first pass through on the spot
The frequency values of corresponding several typical concentrations plus water flow value and frequency conversion screw delivery pump are calculated in experiment.
Measuring method can test a dosage, so by the way of simple point-by-point incremental step measuring and calculating per 10Hz
A thick linear relationship is drawn afterwards, requires dosing value to determine frequency range according to actual concentrations, again with every after reducing the scope
2Hz tests dosage, and so on, most frequency error is narrowed down within 1Hz at last.
3rd step, after being achieved effective control by first, second step for flow of inlet water and into dose, the concentration of liquid
Preparing just being capable of control well.
In this way, PLC control cores can be substituted well, the cost of dispensing system is greatly reduced；It can also carry
For long-range, two kinds of automated dispensing control interfaces on the spot, can flexibly be selected according to field condition.
Although the embodiment of the utility model is described above in association with attached drawing, the utility model does not limit to
In above-mentioned specific embodiments and applications field, above-mentioned specific embodiment is only schematical, directiveness, without
It is restricted.Those of ordinary skill in the art are not departing from the utility model claims under the enlightenment of this specification
In the case of the scope protected, the form of many kinds can also be made, these belong to the row of the utility model protection.
