The potcher rinse water circulatory system in a kind of plastics recovery mixing facilities
Technical field
The utility model relates to plastic milling apparatus, the potcher rinse water circulatory system in particularly a kind of plastics recovery mixing facilities.
Background technology
The method of handling waste or used plastics at present mainly contains burning, landfill and recycling, can produce a large amount of toxic gases but burn, and causes secondary pollution.Landfill can take than large space, behind the landfill in the soil residual plastic flakes can influence the gas permeability of soil again, make crop production reduction.Therefore the Treatment of Waste Plastics Developing Trend in Technology is to recycle.And the recovery approach mainly is divided into two kinds, a kind ofly is with the raw material of the same kind of plastic reclaimed one-tenth or resolves into monomer; Another kind is to be made into comprehensive available other raw materials and the energy.With processing new plastic products and plastic processing raw material behind the waste plastic regeneration is a kind of effective recycling approach.At present, the plastic milling reclaimer mainly by feed system, cleaning systems (by disintegrating machine, shelf, potcher, heat clean, high-speed friction is washed, centrifugal dehydrator, pipeline drying, storing hopper, electric cabinet, transport tape form), twin-screw mixer extrudes unit (being made up of main frame transmission case, lubricating oil cooling system, main motor, screw rod and barrel, auxiliary material feeding machine, temperature control system, vacuum degasser, the automatic net exchanging device of hydraulic pressure, tie rod pelletizing system, the soft water circulatory system, standby redundancy), high-speed mixer, automatic charging machine, air cooling vibratory sieve and forms.
Potcher in the above-mentioned described cleaning systems is to reclaiming the cleaning of plastics, because water consumption is big,
Add that water circulation use is provided with not science, causes waste.
The utility model content
Technical problem to be solved: the utility model is not enough to prior art, in the potcher of plastics recovery mixing facilities, a kind of water wash cycles system with filtering function is provided.
Technical scheme: the potcher rinse water circulatory system in a kind of plastics recovery mixing facilities comprises first potcher, second potcher.The said first potcher bottom is equipped with first header tank, on first header tank, establishes first filter course; The said second potcher bottom is equipped with second header tank, on second header tank, establishes second filter course; Said first header tank is higher than second potcher; The first header tank delivery port inserts second potcher, and the second header tank water outlet is connected in first potcher with outlet pipe through suction pump.
The utility model effect is: owing to adopted technique scheme; The rinse water of first potcher flows into first header tank behind first filter course, supply with second potcher and clean plastics, and the second potcher rinse water is introduced first potcher again behind second filter course; Can make full use of water wash cycles plastics; Using water wisely, simple in structure, convenient and practical.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
See Fig. 1, the potcher rinse water circulatory system in a kind of plastics recovery mixing facilities comprises first potcher 2, second potcher 3.Said first potcher 2 bottoms are equipped with first header tank 7, on first header tank 7, establish first filter course 6; Said second potcher 3 bottoms are equipped with second header tank 4, on second header tank 4, establish second filter course 5; Said first header tank 7 is higher than second potcher 3; First header tank, 7 delivery ports 10 insert 4 water outlets of second potcher, 3, the second header tanks and are connected in first potcher 2 with outlet pipe 9 through suction pump 8.
Feed hopper 1 is put into the plastics of recovery, after first potcher 2 cleans, gets into second potcher 3 once more
(other plastics recovery mixing facilities does not draw among the figure; Potcher equipment in the plastics recovery mixing facilities only draws), the water that first potcher 2 cleaned is handled through first filter course 6 and is flowed into first header tank 7, because first header tank 7 is higher than second potcher 3; The water of first header tank 7 flows into second potcher 3; Rinse water is handled through second filter course 5 and is flowed into second header tank 4, and introduces in first potcher 2 through outlet pipe 9 through suction pump 8, realizes the utilization of water wash cycles.
