Fig. 2 is a kind of operation schematic diagram of the filtration system provided in the embodiment of the present invention.
Specific embodiment
The explanation of following embodiment is referred to the additional illustration, the particular implementation that can be used to implement to illustrate the present invention
Example.The direction term that the present invention is previously mentioned, such as [on], [under], [preceding], [rear], [left side], [right side], [interior], [outer], [side]
Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to
The limitation present invention.The similar unit of structure is with being given the same reference numerals in the figure.
The present invention is in existing developing machine filtration system, when filter is with using time elongated blocking and flow is different
The technical issues of Chang Shi, replacement filter will cause equipment downtime, can reduce device efficiency in this way, the present embodiment is able to solve this
Defect.
As shown in Fig. 2, the filtration system that one embodiment of the invention provides, including water tank 201, the water tank are connected with water pump
202, the water outlet that the water pump is arranged in has two filtering water routes: A filters water route and B filtering water route, two drainages excessively
The water outlet on road is all connected with purge chamber 204.A filtering water route includes filter 203, frequency converter 206 and pneumatic operated valve
207, the frequency converter 206 is electrically connected the water pump 202, to control the operation power of the water pump 202, and then described in control
Either side in the front and rear sides or two sides of the filter 203 is arranged in the output flow of water pump 202, the pneumatic operated valve 207；
B filtering water route includes filter 213, frequency converter 216 and pneumatic operated valve 217, and connection type filters water route with the A.Its
In, two filtering water routes can work alternatively, to start another water route when a water line block wherein.
Further, the filtration system further includes controller 205, the controller 205 and the frequency converter 206, institute
Frequency converter 216 is stated to be connected；The controller 205 is single-chip microcontroller or PLC controller；The controller 205 be arranged manually and from
Two kinds of operating modes are moved, the button switch for switching manually and automatically mode is provided with；
Further, the filtration system further includes pressure sensor 208, water flow sensing unit 209, the water flow sensing unit
209 are arranged at two filtering water outlets, are connected with the controller 205, monitor the stream in the filtering water route
Amount, feeds back the controller 205, optimizes the control to the water pump 202；The pressure sensor 208 is arranged in institute
202 water outlet of water pump is stated, is connected with the controller 205, the pressure condition of 202 water outlet of water pump is monitored, if
Pressure is excessive, then feeds back to the controller 205, the frequency converter frequency conversion of the control of controller 205 just at work, frequency values
Reduce, the operation power of the water pump 202 reduces, and output flow reduces, to protect water route；It further include alarm system, the report
Alert system is made of the display screen and buzzer being arranged on board；The alarm system can generate two class alarm signals: a kind of
Alarm signal, when Traffic Anomaly, the frequency converter had frequency conversion space；Two class alarm signals, when Traffic Anomaly the frequency converter extremely
Limiting value.
When equipment runs well, A filtering water route work, the frequency converter 206 is set as needed for can satisfy board
The lower value of flow, when the filter 203 is with time elongated blocking and Traffic Anomaly is used, the water flow sensing unit
209 monitor A filtering water route flow it is relatively low after, the alarm system generates a kind of alarm signal, feeds back to the control
Device 205, the controller 205 control the frequency converter 206, and conversion frequencies value increases, and the operation power of the water pump 202 increases
Greatly, output flow increases, until the flow that the water flow sensing unit 209 is monitored at A filtering water outlet meets
Setting value.This operating mode is suitable for the filtering water route and slightly blocks, by adjusting the operation power of water pump, to guarantee flow
Meet setting value, it is possible to reduce the replacement number for replacing filter greatly improves the service life of filter, reduce manpower and
Material Cost.
When flow persistent anomaly is relatively low, the 203 frequency conversion value of the filter in A filtering water route has reached the maximum pole
When limit can not continue frequency conversion, the alarm system generates two class alarm signals: display screen display warning, buzzer sounding；The B
The pneumatic operated valve 217 filtered in water route is opened, and the pneumatic operated valve 207 in A filtering water route is closed, and has been automatically switched
At personnel go to replace the filter 203 manually；At this point, the 216 frequency conversion value of frequency converter resets to minimum value, flow is also
Minimum value, the alarm system persistently generate a kind of alarm signal, feed back to the frequency converter 216, and frequency values increase, the water
The operation power of pump 202 increases, and output flow increases, and the B filters the flow in water route as frequency conversion persistently rises, until described
The flow that water flow sensing unit 209 is monitored at B filtering water outlet meets setting value, is recycled with this.This Working mould
When formula is suitable for filtering water route severe blocking or breaks down, by calling spare filtering water route, it can not shut down
In the case where, the filter replace or overhaul to the filtering water route, production capacity caused by shutdown is avoided and damages
It loses, improves the working efficiency of equipment.
Filtration system provided by the invention can be not only used for the cleaning unit of clear water filtering, it can also be used to developer solution filtering
Developing cell.
The invention has the benefit that compared to the filtration system of existing developing machine, the filtering of developing machine of the invention
System is by way of increasing and filtering water route, and when filter is with time elongated blocking and Traffic Anomaly is used, system passes through
Frequency converter frequency conversion guarantees flow to extend the service life of filter, and frequency converter automatically switches to spare filtering after reaching capacity
Water route works on, convenient for personnel manually go repair or replace filter, thus solve in the prior art, because personnel operation or
Person's flow variation and caused by capacity loss, producing line overall equipment efficiency.comprehensive efficiency of equipment index reduce etc. technical problems.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
