As depicted in figs. 1 and 2, this utility model provides a kind of coating filtration system from pre-washing function, including for
Painting material screen 4, pump 3, the accumulator tank 1 depositing coating and the control module of filter coating material, is coated with material screen 4 and is provided with stock inlet 41, pulp
Mouth 42, rinse mouth 44 and screening reject outlet 43；Be provided with oleo stock outlet, the import of described pump and the oleo stock outlet of accumulator tank 1 are passed through
Pulp-absorbing pipe 101 connects, and delivery side of pump is connected by pulp-inlet pipe 102 with stock inlet 41；It is communicated with on grout outlet 42 after filtering
The good slurry outlet pipe 103 that coating is drawn, good slurry outlet pipe 103 is provided with the 3rd valve 53；Rinse mouth 44 is communicated with accessible clear
First flush pipe 107 of water, the first flush pipe 107 is provided with the second valve 52；Screening reject outlet 43 is communicated with and processes pond 7 with screening reject
The scum pipe 104 communicated, scum pipe 104 is provided with the first valve 51；Connect between stock inlet 41 and grout outlet 42 and have for examining
Survey the measurement pipe 100 of pressure differential at two, measure pipe 100 and be provided with pressure difference detection device 50, pressure difference detection device 50 and control
Molding block is electrically connected with；On good slurry outlet pipe 103, between grout outlet 42 and the 3rd valve 53, it is also associated with return duct 106
One end, the other end of return duct 106 is connected with accumulator tank 1, and return duct 106 is provided with the 5th valve 54；Pulp-inlet pipe 102 and returning
It is communicated with between flow tube 106 and lets out slurry pipe 105, let out slurry pipe 105 and be provided with the 4th valve 55；Described first valve the 51, second valve
52, the 3rd valve the 53, the 4th valve 55 and the 5th valve 54 are electromagnetic valve, are electrically connected with control module respectively.
Described pressure difference detection device 50 can be pressure difference transmitter, and pressure difference transmitter is electrically connected with control module,
The pressure difference value of the stock inlet 41 recorded and grout outlet 42 position can be measured and institute's measured value is transferred to control module
In.
In normal filtration work process, first valve the 51, second valve the 52, the 4th valve 55 and the 5th valve 54 are in
Closed mode, the 3rd valve 53 is in open mode.
When pump 3 starts rotary work under the drive of motor 2, draw accumulator tank 1 from oleo stock exit by pulp-absorbing pipe 101
Interior oleo stock, is passed through pulp-inlet pipe 102 and is transported to be coated with in material screen 4 by stock inlet 41, complete to filter, pass through in being coated with material screen 4
The good slurry of filter is got rid of by good slurry outlet pipe 103, is delivered among the equipment of next procedure.
When filtering for a long time owing to being coated with material screen 4, internal screening reject accumulation is more, when filter effect is poor, and stock inlet 41 and going out
The pressure differential on slurry mouth 42 both sides can increase therewith due to throttle effect.
When pressure difference transmitter detects stock inlet 41 and grout outlet 42 pressure difference value reaches 2bar, control module can be made
The instruction that deslagging cleans, control module can control the first valve the 51, second valve the 52, the 4th valve 55 and 54 dozens, the 5th valve
Opening, the 3rd valve 53 is closed, and system enters rinses operation.
Now, the 3rd valve 53 of closedown has also cut off the connection of the equipment with next procedure, prevents in flushing process
Serosity is flowed in the equipment of next procedure, the oleo stock being pumped out can by let out slurry pipe 105 and return duct 106 be passed straight back to store
In groove 1, suppressing bad to prevent pump 3 because pressure is excessive, and the injection stopping oleo stock being also beneficial to the work of follow-up cleaning screening reject；Long-pending
Tire out the screening reject among painting material screen 4 to be drained into by scum pipe 104 among screening reject process pond 7；Clear in first flush pipe 107
Water is injected into being coated with in material screen 4, and the pressure rinsing clear water in the first flush pipe 107 is at least 3bar, with the flushing effect guaranteed
Rate.Clear water can dilute the screening reject concentration being coated with in material screen 4, has the most also rinsed the screen cylinder being coated with in material screen 4 so that be trapped in screen cylinder
Impurity peel off, and then improve the efficiency of filtration.
Along with in being coated with material screen, screening reject is discharged, the raising of screen cylinder filter efficiency, the pressure reduction meeting of stock inlet 41 and grout outlet 42
Being gradually reduced, typically when being decreased to below 0.6bar, control module can control first valve the 51, second valve the 52, the 4th valve
Door 55 and the 5th valve 54 are closed, and the 3rd valve opens 53, and system enters and filters work process normally, above just complete one
Individual filtration, rinse and filter automatically control and operate circulation.
Being communicated with the second flush pipe 108 of accessible clear water on scum pipe 104, the second flush pipe is provided with the 6th valve
56, the 6th valve 56 is electromagnetic valve, and control module is electrically connected with, and the 6th valve 56 is closed when normal filtration,
Also sending instruction in flushing process control module at first to be opened by the 6th valve 56, at this moment clear water will be by the second flush pipe
108 enter among scum pipe 104, are rinsed, and prevent scum pipe 104 because screening reject is too much, and result in blockage, affect deslagging
Efficiency, after flushing process completes, control module can send instruction, allows the 6th valve 56 close, is transformed into filtration work
Process.
The clear water accessed in first flush pipe 107 and the second flush pipe 108 is warm water, and warm water has higher flushing effect
Really, can more easily alluvial and the screening reject remained in screen cylinder be developed.
It is coated with material screen 4 and is provided with air vent 44, air vent 44 connects and has the exhaustor 109 connected with screening reject process pond,
During normal work can the external aerofluxus when coating injects, be more favorable for pumping into of coating, and when filter efficiency step-down, arrange
QI KOU 44 also plays the function of overfall, when pump 3 constantly pumps into coating, and the liquid level being coated with in material screen 4 constantly raises, and fills coating
When sieving 4, unnecessary coating can overflow from air vent 44, is directed into screening reject from exhaustor 109 and processes in pond 7.
The bottom of described accumulator tank 1 is inclined plane, connects in the bottom of inclined plane and has the blowdown connected with screening reject process pond 7
Pipe 107, described blow-off pipe 107 is provided with blowoff valve 57, and the bottom surface of inclination contributes to piling up the impurity in oleo stock, by close in oleo stock
Spend bigger impurity, granule etc. and collect the bottom of inclined plane, can arrange with manual unlocking after a period of time has been piled up in accumulation
The impurity collected, granule etc. are discharged outside accumulator tank 1 by dirty valve 57, improve the cleannes of oleo stock in accumulator tank 1.
In the description of this specification, reference term " embodiment ", " some embodiments ", " example ", " specifically show
Example " or the description of " some examples " etc. means to combine this embodiment or example describes specific features, structure, material or spy
Point is contained at least one embodiment of the present utility model or example.In this manual, the schematic table to described term
State and be not necessarily referring to identical embodiment or example.And, the specific features of description, structure, material or feature can be
Any one or more embodiments or example combine in an appropriate manner.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right
Property scope.
