Description
Technical field
The utility model relates to a kind of plastic pellet filter, is the equipment that a kind of specialty is used for filtering different-grain diameter scope plastic pellet.
Background technology
Such as the ABB-PLC Based Intelligent Control, full-automatic unmanned worker's operation, mainly by filter cylinder, stainless steel wedge shape filter screen, PLC controller etc. partly form.Adopt metallic spatula to remove the impurity of screen wall.Can freely select manually-operated or automatically control.Be used for: remove the granule foreign in the various high viscosity liquid crystal, be applicable to fine chemistry industry, oil product, food medicine, the occasions such as water treatment.
Existing plastic pellet filter comprises traditional filter cake formula filter, or deep bed filter, such as pocket type or filer element type, has following problems:
1. self-cleaning is difficult, because the height compressible type of plastic pellet particle, plastic pellet is difficult to form filter cake in cartridge surface in the process of filtering plastic particle so cause, traditional filter cake formula filter can't be removed automatically to plastic pellet, and deep bed filter can not be realized self-cleaning;
2. can not realize dried slag discharge, some enterprises select when processing plastic pellet and strike off the formula filter, but because the proportion of most of plastic pellet is less than liquid specific gravity, so cause in the filter backwash process plastic pellet deslagging tank on the contrary upwards to swim in liquid upper at the plastic pellet in the process of striking off of scraper owing to the reason of self proportion can't be deposited to downwards, cause the impurity that when deslagging, only has seldom to discharge, and contain large quantity of fluid in the impurity of discharging, need to realize dried slag through further filtering.Because most of impurity still stays filter core inside, cause next that filter very easily stops up, affect the effect of continuous operation;
3. can not continuous operation.Adopt the deep bed filters such as traditional pocket type, core formula; although can realize the effect of dried slag, in tapping process, all need filter is shut down at every turn, and extract filter bag out, filter core cleans; continuous operation be can't realize, and periodic replacement filter bag and filter core needed.Cause the raising of cost.
The utility model content
Technology to be solved in the utility model is always: a kind of plastic pellet filter is provided, realizes that the solid plastic particle of discharging only contains micro liquid, conveniently immediately reclaim, need not further to remove the liquid in the impurity again.
Described in the utility model always by lower technical scheme solution: a kind of plastic pellet filter, comprise that the bottom is filter cylinder, filter core and the PLC controller of conical cavity, wherein:
Described filter cylinder top is provided with loam cake, and filter core is located in the filter cylinder, and the side-lower of filter cylinder is provided with inlet, and the side top is provided with liquid outlet, and the bottom of filter cylinder arranges slag-drip opening, is controlled by residual cake valve;
Described filter core is the wedge shape filter structure, and a scraping disc is fixed on the top in the described wedge shape filter screen filter core, and the cylinder interlock with being fixed on upper cover part presses down along the filter cylinder inwall;
At the described fixedly drainage tube that covers, this drainage tube extends the filter cylinder below through scraping disc.
The utility model reaches customer requirement mainly for the treatment of the solid plastic particle of proportion in the pending liquid less than pending liquid to guarantee the liquid after the filtration.
Principle of the present utility model is: it is inner that pending liquid flows into wedge shape net filter core by inlet valve, and it is inner that the solid impurity particle is blocked in wedge shape net filter core, and clean fluid passes through filter core, discharged by liquid outlet.When the solid impurity particle of filter core inside runs up to when a certain amount of; cylinder drive scraping disc moves down the solid plastic particle that will be suspended in filter core inside and is pressed in the conical cavity of bottom; when scraping disc is gone to desired location, open residual cake valve, the impurity such as solid plastic particle are discharged.Cylinder drives scraping disc and moves upward to original position when closing residual cake valve after impurity is discharged, and circulation this moment is finished.
For improving the deslagging effect, on the such scheme basis, described drainage tube one end is fixed on upper cover part, and the other end is passed down through scraping disc and stretches into the tapered shaped can that is positioned at wedge shape net filter core bottom.
For realizing better automatically control, on the such scheme basis, described inlet is provided with liquid feed valve, and liquid outlet is provided with liquid valve, and described liquid feed valve, liquid valve, residual cake valve and cylinder are controlled by the PLC controller.
When pressing down for the prevention scraping disc, impurity enters the filter core top through scraping disc, and described scraping disc is solid construction, external diameter and filter core internal diameter coupling.
But be the continuity that realizes filtering, described mozzle is the wedge shape web frame.
The utility model provides the method for operating for above-mentioned plastic pellet filter:
Pending liquid enters filter cylinder from inlet, in filter process, the impurities accumulation that comprises plastic grain when filter core inside is during to set amount, the scraping disc of filter core inside begins to move downward, and moves down in the process at scraping disc, and impurity is pressed in the tapered shaped can, and liquid flows out by the mozzle on the scraping disc, at this moment, open residual cake valve, discharge impurity.
Superiority of the present utility model is: can realize that the solid plastic particle of discharging only contains micro liquid, can immediately reclaim, need not further to remove the liquid in the impurity again.Whole Equipment adopts PLC control, and whole filtration need not manpower, but and the filter continuous operation, need not to shut down.
