Summary of the invention
The object of this invention is to provide a kind of high viscosity liquid processing control apparatus and method of work without dismounting, on-line cleaning, Automatic Control.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of high viscosity liquid processing control apparatus, comprises liquid flowing valve, filter, fluid valve, drain tap, blowback valve, cleaning fluid backwash valve, air intake valve, vent valves, slag-discharging valve, fluid level transmitter and pressure difference transmitter.Described filter is provided with bottom and is provided with inlet, floss hole and slag-drip opening, and middle part is provided with liquid outlet, and top is provided with exhaust outlet and air inlet; Described filter inlet connects liquid flowing valve, and floss hole connects vent valves, and slag-drip opening connects slag-discharging valve; Described liquid outlet connects purified liquor outlet house steward; Described exhaust outlet connects drain tap, and air inlet connects air intake valve; Described purified liquor outlet house steward has back blow port and cleaning fluid backwash mouth, connects respectively blowback valve and cleaning fluid backwash valve, and purified liquor outlet connects fluid valve; Described pressure difference transmitter high-pressure mouth and low pressure port are connected respectively inlet and the liquid outlet of filter.
Filter of the present invention adopts the powder sintered filter core of high-precision metal, and filter interior is provided with ultrasonic oscillator.
High viscosity liquid is processed a method of work of controlling, and comprises the following steps:
Step a, topping up: open liquid flowing valve and drain tap, viscose glue enters filter, fluid level transmitter Real-Time Monitoring liquid level, sets the topping up time when fluid level transmitter shows high liquid level or reaches, and stops topping up;
Step b, filter: open outlet valve, close drain tap, viscose glue is removed solid particle polluter or colloid through filter, impurity is filtering original paper surface formation cake layer, through filter, outlet enters spinning-drawing machine to clean viscose glue, and filtration end point, by time and pressure reduction control, ensures filter safe operation;
Step c, binder removal: after filtration finishes, close filter liquid flowing valve and fluid valve, open air intake valve and vent valves, under the effect of gas pressure, open air intake valve and close filter terminal valve, residual viscose glue in discharge filter,
Steps d, backwash is soaked: open cleaning fluid backwash valve and drain tap, cleaning fluid is oppositely by filter core, and by filter cake wash-out, cleaning fluid is full of after filter, soaks a period of time;
Step e, blowback: open blowback valve, pass into purge gas, utilize blowback pressure by filter cake stripping from filter element, the blowback time was controlled by the time;
Step f, ultrasonic wave: start ultrasonic oscillator, ultrasonic wave bubble impact in cleaning fluid can destroy insoluble dirt in filter core hole, make its dispersion come off with solution in;
Step g, deslagging: open slag-discharging valve, in the time that liquid level drops to low liquid level or reach the setting deslagging time, time-delay closing slag-discharging valve.
The invention has the beneficial effects as follows, ensureing viscose glue quality in principle, the defect and the weakness that exist for the control device of current high viscosity liquid processing are improved and strengthen, by optimizing the control method of existing apparatus, package unit is effectively realized the on-line cleaning to filter, by introducing ultrasonic cleaning technology, clean more thoroughly, greatly reduce filter core maintenance time and cost of labor.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is the process chart of the control device of high viscosity liquid processing of the present invention.
Fig. 2 is the control method figure of the control device of high viscosity liquid processing of the present invention.
Detailed description of the invention
As shown in Figure 1, specific embodiments of the invention, mainly comprise the following steps: viscose glue enters filter, when filling to the high liquid level of filter, fluid level transmitter sends high liquid level signal or reaches sets 10 minutes topping up time, now stops topping up, enters the normal filtration stage.Set filtration time 48 hours when filter inlet outlet pressure differential reaches 0.5～0.6MPa or reaches, now stop filtering.Pass into Compressed Gas from filter top, residual viscose glue in filter is discharged, after draining, viscose glue passes into cleaning fluid, fill to the high liquid level of filter, soak 2 hours, oppositely pass into Compressed Gas and clean the filter cake on filter cake surface, blowback finishes to start ultrasonic oscillator, the tank cleaning liquid inside that vibrates after 0.5 hour together with filter cake impurity through slag-drip opening discharge filter.
