Description
Technical field
The present invention relates to a kind of waste polyethylene plastics that utilize directly to manufacture a finished product the method for water delivery plastic tube, specifically waste polyethylene plastics through and cleaning and crush the method being produced water delivery plastic tube by two extruders, belong to the plastic reclaimed product field of waste polyethylene.
Background technology
Along with the development of agricultural production is not lived at the mercy of the elements; solve the plastic pipe of water delivery needed for crop irrigation, now extensively utilize waste polyethylene plastics first to pulverize cleaning, after adding the cooling of hot-extrudable bar by extruder; be cut into particle with pelleter again, become the raw material producing vinyon tubing.The plastic pipe cost of such production is very high, not only causes the waste of a lot of resource, and is unfavorable for environmental protection.
Summary of the invention
Goal of the invention
The invention provides a kind of waste polyethylene plastics that utilize directly to manufacture a finished product the method for water delivery plastic tube, its objective is to reduce production cost, energy-saving and emission-reduction, protection of the environment, also solving the problem of human resources deficiency.
Technical scheme
Utilize waste polyethylene plastics directly to manufacture a finished product the method for water delivery plastic tube, it is characterized in that: the method step is as follows:
(1) cleaning is pulverized in the waste polyethylene plastics classification of reclaiming to dry, as raw material for standby;
(2) with semi-automatic continuous glassware, constantly the raw material got ready is continued into First extruder; By semi-automatic or full-automatic net-changing device, filter out pure hot tire material;
(3) from the hot tire material that First extruder is extruded, naturally flow into the charging aperture of second extruder in below by gravity, the heat material of second extruder by front end die head, calibration sleeve cooling, metering, draw, search volume and produce finished product.
The pure hot tire material temperature degree filtered out in step (2) is 195 DEG C-205 DEG C.
In step (3), in second extruder, pressure remains on 25mpa-30mpa.
Advantage and effect
Advantage of the present invention and good effect as follows:
Normal production one ton of vinyon tubing needs electric 400-500 degree, artificial 3 (8 hours × 3 people), cooling water 10-15 cubic meter, mechanical depreciation price for repairing etc. now.Approximately need RMB 600 yuan.
Utilize technology of the present invention to produce one ton of tubing and just can economize 600 yuan.And the raw material produced reduces the process once plastifying decomposition, adds the service time of tubing.Within one day, produce one ton in a set of machine like this, annual product 300 days × 600 yuan=180,000, benefit is very considerable, reduces much unnecessary waste, is suitable for applying.

detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is described further:
The present invention proposes a kind of waste polyethylene plastics that utilize directly to manufacture a finished product the method for water delivery plastic tube, not only economize on electricity, economize on water, saving of labor, save time, reduce transport and without packaging bag, significantly reduce production cost; As shown in fig. 1, concrete steps are as follows:
(1) the waste polyethylene plastics reclaimed are pressed film, Hollow barrel bottle, color classification, film water is broken into less than 25 square centimeters, and bucket bottle water is broken into the cleaning of nail cover size and dries, as raw material for standby.
(2) with semi-automatic continuous glassware, constantly the raw material got ready is continued the First extruder charging aperture 11 into Electromagnetic Heating, by semi-automatic or full-automatic net-changing device 12, filter out pure hot tire material (195 DEG C-205 DEG C).The effect of this extruder, is to utilize electromagnetic heating technique, and thermal efficiency high power is large, and easy temperature control system, accomplishes not shut down replacing screen pack with semi-automatic or full-automatic net-changing device, ensures that the hot tire material of second extruder uninterruptedly can continuous seepage.
(3) from the hot tire material that First extruder 1 is extruded, naturally second the extruder charging aperture 21 in below is flowed into by gravity, when hot tire material is by second extruder 2, can mediate with wind or water to the temperature of hot tire material, then draw by front end die head 23, calibration sleeve (at front end die internal) cooling, metering, draw-gear 24, search volume, equally with common pipe machine produce finished product.Second extruder plays the effect (forward lower part of die head 23 is provided with the tank 22 of cooling) of mediating to the hot material temperature degree of coming in, and can use the method for blower fan, water ring; Also want the supplied materials of buffered excess, reconcile the rotating speed of screw rod, pressure constant in maintenance machine, at 25mpa-30mpa, guarantees that pipe thickness is consistent.
Embodiment 1:
The waste polyethylene plastics reclaimed are pressed film, Hollow barrel bottle, color classification, and film water is broken into less than 25 square centimeters, and bucket bottle water is broken into the cleaning of nail cover size and dries, as raw material for standby; With semi-automatic continuous glassware, constantly the raw material got ready is continued into First extruder; By semi-automatic or full-automatic net-changing device, filter out pure hot tire material; The pure hot tire material temperature degree filtered out is 195 DEG C DEG C; From the hot tire material that First extruder is extruded, naturally flow into the charging aperture of second extruder in below by gravity, the heat material of second extruder by front end die head, calibration sleeve cooling, metering, draw, search volume and produce finished product; In second extruder, pressure remains on 25mpa.
