Description

A kind of steel pipe heat is coated with the polyethylene anticorrosive coating device
Technical field
The utility model is that a kind of steel pipe heat that steel pipe heat is coated with polyethylene anticorrosive coating is coated with the polyethylene anticorrosive coating device.Relate to the device that the thermoplastic moulding uses, the general corrosion protection and the pipe-line system technical field of metal material.
Background technology
The aseptic technic of steel pipe has varied.Wherein the hot coating technology of steel pipe polyethylene (being commonly called as individual layer PE technology) is a kind of simple and inexpensive technology of processing.Comparatively advanced now is Japan's first homogeneous tube showering technology high-frequency.It is a whole steel pipe to be sent in the showering device it is rotated around tubular axis, the polyethylene showering groove that places the top simultaneously with gravity to whole steel pipe showering polyethylene powders, after being coated with a steel pipe steel pipe is sent, treat to carry out water-cooled when the nature cooling is below 100 ℃ again, unnecessary polyethylene powders circulation is reclaimed.Its showering groove imposes vibration by cam mechanism when showering, polyethylene powders is evenly drenched down, and steel pipe is then blocked two ends and imposed rotation by rotating mechanism.This technology can be carried out showering to a homogeneous tube simultaneously, with regard to the time of showering, obviously is faster, and the quality of showering also can guarantee.But owing to be interrupted production, interior, particularly going out cooling off naturally behind the pipe more needs the long period inlet pipe and the Time Calculation that goes out pipe.The time of in fact producing a steel pipe still is long, and production efficiency is not high, and production equipment is also very huge, has improved production cost relatively.
The utility model content
The purpose of this utility model is that design a kind ofly can be produced continuously, efficient height, quality are good, the simple steel pipe heat of equipment is coated with the polyethylene anticorrosive coating device.
Steel pipe polyethylene heat is coated with technology, be its heat to be melted the steel pipe outer surface that high density, low-density or the LLDPE powder mode by powder gravity effect showering is coated in through heating in medium frequency, utilize the performance of trickling naturally of melt liquid, equably attached to the outer surface of steel pipe, through after the condensation, form tight anticorrosion coating.So, this steel pipe heat is coated with the polyethylene anticorrosive coating device and (sees Fig. 1, Fig. 2) equally also include: a showering case 2 with prior art, top outside showering case 2 stretch in the showering case 2 rectangular funnel-form stock chest 6 and under showering groove 1, showering groove 1 vibrating device, showering groove 1 a slit governor motion, steel pipe 3 axial rotating mechanisms and a polyethylene powders that is positioned at showering case 2 middle parts loops back receiving apparatus, but be characterized in that an electromagnet actuating mechanism gauge tap showering groove 1 undermost startup plate 13 is respectively arranged on side both sides of 1 wide of showering groove, in showering groove 1, start on the plate 13 showering slit and governor motion thereof are arranged, one cover support roller, 4 steel pipe conveying mechanism are respectively arranged in production line upstream side and production line downstream outside showering case 2 middle part casees---the cooling pond, and residue polyethylene powders groove and retracting device are arranged at showering case 2 bottoms.What adopt in the electromagnet actuating mechanism here is alternating electromagnet, it is controllable switch showering groove 1 both, opens showering groove 1 when promptly needing showering, and the polyethylene powders in the stock chest 6 is drenched down by the slit of showering groove 1, when not showering, close showering groove 1, stop the following pouring of polyethylene powders; Electromagnet 17 is when powering up work simultaneously, be when drenching under the polyethylene powders, because added in the electromagnet 17 is alternating current, its frequency is 50Hz, electromagnet 17 still has little shaking by the frequency of alternating current after powering up adhesive, this vibration also acts on showering groove 1 by actuating mechanism, has also played the vibration effect to showering groove 1, and the polyethylene powders in the showering groove 1 can evenly be drenched down.And electromagnet actuating mechanism (seeing Fig. 2, Fig. 3) by a usefulness nut 22 be fixed on the support 18 solid one "  " shape starting bar 16 of core iron of electromagnet 17, the middle right corner of this starting bar 16 is by pin 20 and the support 7 hinges location that is connected in stock chest 6 outsides, in the earhole outside its lower end insertion showering groove 1 undermost startup plate 13, starting plate 13 is the rectangular flats that insert in the showering groove 1, the punching of one ear is respectively arranged on the both sides in its outside, and hook one spring 10 is to the hole of showering groove 1 corresponding opposite side.Its course of work is when electromagnet 17 does not power up, because the pulling force of spring 10 will start plate 13 and be withdrawn under the showering groove 1, showering groove 1 is sealed; After electromagnet 17 powers up, core iron is sucted, by the effect of starting bar 16, startup plate 13 is pulled out, showering groove 1 end opening is opened.Showering groove 1 slit and governor motion thereof such as Fig. 2, Fig. 3 and shown in Figure 4, it by on starting plate 13 near 1 liang wide of showering groove locate each by strip before adjustable plate 14 and aft ramp 15, outside 1 liang of leptoprosopy of showering groove, be inserted into two plates 11 between the forward and backward adjustable plate 14,15 and 4 and regulate bolts 12 and form.Width less than showering groove 1 inwall apart from the both sides of the front and back adjustable plate 14,15 of half the adjustable plate ear 21 vertical and porose that respectively be connected with the plate face, pass the hole on this ear and be slidingly connected by the adjusting bolt 12 that outside showering groove 1, penetrates, regulate bolt 12 and pass the cinclides internal thread of showering groove 1 and cooperation with it, the outer end of regulating bolt 12 be connected hex nut or wing nut, there are forward and backward adjustable plate 14,15 telescopic chutes or the press strip that is connected in 1 liang of wide inboard of showering groove on inwall.Plate 11 is a rectangular flat, and handle is arranged outward, is located by the groove on the cell wall of 1 liang of leptoprosopy of showering groove.Two plates 11 can pull out, advance, to regulate the length in showering groove 1 showering slit.And front and back adjustable plate 14,15 can move forward and backward forward and backward adjustable plate 14,15 by 12 push-and-pulls of 4 adjusting bolts in showering groove 1, reaches the requirement to the showering gap width.Steel pipe 3 connecting gears are two pairs of support rollers 4, the rubber tire that every support roller 4 drives for band, and two support roller driving directions of every pair of support roller 4 are opposite, intersect angle with steel pipe 3 in direction of advance and are slightly less than 90 ℃, steel pipe 3 rotated a circle advance 1cm; Distance between the two pairs of support rollers 4 is slightly less than half length of whole steel pipe 3, generally with little 20cm for well.For the distance between 3, two pairs of support rollers 4 of 12 meters long steel pipes is 5.8m, and such 12 meters long steel pipes 3 just can transmit on this connecting gear.Transmission can make steel pipe 3 have some to fluctuate up and down in showering case 2 like this, but can't influence the quality of showering, and just the import and export of steel pipe 3 turnover showering casees 2 want more bigger.For anti-powder escapes, can add the flexible material curtain at import and export, or import and export and showering case 2 flexibly connect.In addition, unlikely accumulation when making polyethylene powders pour stock chest 6 into, influence is evenly drenched down, is added with down " V " shape buffer board 19 in the centre of showering groove 6 middle and upper parts.In order to install and clear up showering groove 1 convenience, stock chest 6 is split with showering groove 1, and the outer a plurality of screws 8 of folder pad 9 usefulness that the junction is connected by stock chest 6 and showering groove 1 are tightened and are connected.
