Abstract
The invention relates to a cooling device used for extruding a hard pipe. The cooling device comprises a cooling chamber, wherein through holes are formed in two sides of the cooling chamber, and the molded and sized hard pipe passes through the cooling chamber from the through holes in two ends of the cooling chamber. A spraying pipe is arranged in the cooling chamber, and is a spiral spraying pipe, and spraying holes are formed in the spraying pipe. A liquid collecting tank is arranged below the cooling chamber, and cooling liquid sprayed from the spraying pipe flows back to the liquid collecting tank. The liquid collecting tank is connected with a booster pump through a return pipe, the booster pump is connected with the spraying pipe through a liquid supply pipe, and a liquid baffle plate is arranged at the through hole in one side of the cooling chamber; and a filter is arranged between the return pipe and the booster pump. The number of spiral coils of the spraying pipe is not less than two. A plurality of liquid dropping pipes are arranged between the cooling chamber and the liquid collecting tank; and the spraying pipe in the cooling chamber of the cooling device provided by the invention is the spiral spraying pipe, and a water curtain sprayed from the spiral spraying pipe surrounds the sized hard pipe, so that the hard pipe is uniformly cooled, and deformation during a cooling process is effectively prevented.
Description
Technical field
The present invention relates to cooling device field, particularly relating to a kind of cooling device for extruding hard tube.
Background technology
Plastic pipe is as the important component part of chemical building material, and with the performance that it is superior, health, environmental protection, low consumption etc. are accepted extensively by users, mainly contain UPVC drainpipe, UPVC feed pipe, PAP, and these are several for polyethylene (PE) water-feeding pipes.Pipe production line is made up of control system, extruder, head, sizing cooling system, hauling machine, planet cutter sweep and tilting trestle.Wherein, qualitative cooling system is used for shaping tubing to carry out shaping and lowering the temperature.Common cooling system inhomogeneous cooling when applying is even, especially large diameter tubing, and when lowering the temperature, regional area is uneven by liquid, easily causes tubing to produce distortion due to different parts temperature contrast in temperature-fall period.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of cooling device for extruding hard tube, instant invention overcomes extrude hard tube shape in process after cooling link to be heated uneven defect, effectively prevent from producing distortion in hard tube temperature inequality in cooling procedure.
The present invention is achieved through the following technical solutions:
For extruding a cooling device for hard tube, comprise cooling chamber, cooling chamber both sides are provided with port, shaping and hard tube after sizing from the port at cooling chamber two ends through cooling chamber.Be provided with shower in described cooling chamber, described shower is screw spraying pipe, and shower is provided with spray apertures.Be provided with catch box below described cooling chamber, be back in catch box from the cooling fluid of shower ejection.Described catch box is connected with booster pump by return duct, and booster pump is connected with shower by feed pipe, and the passage port of described cooling chamber side is provided with liquid barrier.Described cooling chamber, booster pump etc. are fixed on base.
Filter is provided with between described return duct and booster pump.
The spiral number of turns of described shower is no less than two circles.
Multiple declining liquid tube is provided with between described cooling chamber and catch box.
Compared with prior art, the invention has the beneficial effects as follows: the shower in cooling chamber of the present invention is screw spraying pipe, from screw spraying pipe ejection water curtain around sizing after hard tube, make hard tube obtain uniform decrease in temperature cooling, effectively prevent in cooling procedure produce distortion.

Fig. 1 is structural representation of the present invention;
In figure: 1, base; 2, booster pump; 3, catch box; 4, declining liquid tube; 5, port; 6, cooling chamber; 7, feed pipe; 8, shower; 9, spray apertures; 10, liquid barrier; 11, filter; 12, return duct.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Described a kind of cooling device for extruding hard tube, as shown in Figure 1, comprises cooling chamber 6, and cooling chamber 6 both sides are provided with port 5, shaping and hard tube after sizing from the port 5 at cooling chamber 6 two ends through cooling chamber 6.Be provided with shower 8 in cooling chamber 6, shower 8 is screw spraying pipe, shower 8 is provided with spray apertures 9.Below cooling chamber 6, be provided with catch box 3, the cooling fluid sprayed from shower 8 is back in catch box 3.Catch box 3 is connected with booster pump 2 by return duct 12, and booster pump 2 is connected with shower 8 by feed pipe 7, and cooling fluid adds and is sent in shower 8 by booster pump 2.Port 5 place of cooling chamber 6 side is provided with liquid barrier 10, and exported from the port 5 being provided with liquid barrier 10 by the hard tube after spraying, the cooling fluid sticked on hard tube outer wall is dropped on liquid barrier, and it is outside that liquid barrier 10 prevents cooling fluid to be dropped in cooling chamber 6.Described cooling chamber 6, booster pump 2 etc. are fixed on base 1.
Be provided with filter 11 between described return duct 12 and booster pump 2, filter 11 filters out the residue in the cooling fluid of backflow, prevents residue from blocking shower 8.
The spiral number of turns of described shower 8 is no less than two circles, and the very few meeting of the spiral number of turns of shower 8 causes hard tube to be subject to liquid uneven, the uniformity of impact cooling.
Be provided with multiple declining liquid tube 4 between described cooling chamber 6 and catch box 3, cooling fluid is flowed in catch box 3 by declining liquid tube 4.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
