Background technology:
At present, the on-the-spot metal corrosion preventing method of generally taking is a flame spraying, and this anti-corrosion method is because there is following problem in the limitation of its technology: the workpiece reparation that (1) powder outlet quantity is few, can only be used for small size is not suitable for the on-the-spot coated of large tracts of land.(2) to the temperature control requirement height of workpiece to be machined, and because the difficult control of temperature of the on-the-spot work piece of manually-operated, so the coating peel strength is difficult to guarantee.(3) coating thickness restricted＜0.8mm.(4) easily produce the bridging phenomenon.(5) spray the easy heat ageing of coating repeatedly.And there is following problem equally in electrostatic spraying: it is low that (1) receives the powder rate, and the Powder Recovery rate can only reach 85%.(2) coating layer thickness restricted＜0.3mm.(3) site operation levelling difficulty, be not suitable for the on-the-spot coated of large tracts of land.The anti-corrosion method that often adopts both at home and abroad has in addition: fiberglass is anticorrosion or epoxy resin is anticorrosion, this anti-corrosion method is because the ageing resistance of its material itself is poor, under the ultraviolet especially in the open direct irradiation, its aging speed is very fast, general service life is at 2-5, because be full of cracks easily such as fiberglass or epoxy resin and anticorrosion matrix steel tube etc. declines to a great extent antiseptic effect, again because the limitation of fiberglass or the corrosion resistant performance of epoxy resin own is restricted its range of application.Also have anti-corrosion methods such as some anticorrosive paints, owing to be difficult for grasping rule, coating quality is difficult to be guaranteed, and adds again that easily " peeling " such-and-such defective such as peels off, and makes to use to be restricted.
The utility model content:
The purpose of this utility model provides a kind of favorable anti-corrosion effect, good weatherability, easy construction, cost is low, and large-scale metal structure, pipeline, jar, the groove that can be widely used in industries such as oil, chemical industry, electric power, metallurgy, medicine, environmental protection spray the device of thermoplastic powder.
Technical solution of the present utility model is: the device of a kind of large-scale metal structure, pipeline, jar, groove spraying thermoplastic powder, it is characterized in that: thermoplastic powder feed mechanism is arranged, thermoplastic powder feed mechanism is connected with electrostatic gun, other has one group of flame gun, and flame gun is connected with the burning feed mechanism.
In the thermoplastic powder feed mechanism described in the utility model the powder feeding tube is arranged, the powder feeding socket joint has powder feeding pump, also is connected with air compressor.The powder feeding tube also is connected to the boiling tube that is connected with air compressor.Electrostatic gun is connected with electrostatic generator.The burning feed mechanism that is connected with flame gun adopts the burning gases feed mechanism.The burning gases feed mechanism is oxygen cylinder and acetylene cylinder.One group of flame gun is constituted single rifle by 2-4.Flame gun adopts the remelting rifle.
The beneficial effects of the utility model are: novel structure is simple, it is ingenious reasonable to design, concentrated the advantage of flame-spraying and two kinds of methods of electrostatic spraying, be particularly suitable for the anticorrosive construction of on-the-spot large-scale metal steel structure, pipeline, jar, groove, coating stripping intensity height, the thickness that site operation obtains can be regulated (the thickest 4MM of reaching), attractive in appearance, the favorable anti-corrosion effect of the effective smooth surface of coating levelling arbitrarily, good weatherability, easy construction, cost is low.Can be widely used in large-scale metal steel structure, pipeline, the jar of industries such as oil, chemical industry, electric power, metallurgy, medicine, environmental protection, the on-the-spot anticorrosive construction of groove, be the antiseptic update technology of conventional on-site flame-spraying preservative treatment, electrostatic spraying preservative treatment, fiberglass preservative treatment or epoxy resin.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings:
Accompanying drawing is the structure drawing of device of a kind of large-scale metal structure of the present utility model, pipeline, jar, groove spraying thermoplastic powder.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model, and thermoplastic powder feed mechanism is arranged in this embodiment, and thermoplastic powder feed mechanism is connected with electrostatic gun 3, and other has one group of flame gun 4, and flame gun 4 is connected with burning feed mechanism 5,6.In the wherein said thermoplastic powder feed mechanism powder feeding tube 10 is arranged, powder feeding tube 10 is connected to powder feeding pump 9, also is connected with air compressor 11.Powder feeding tube 10 also is connected to the boiling tube 13 that is connected with air compressor 11.Electrostatic gun 3 is connected with electrostatic generator 7.The burning feed mechanism that is connected with flame gun 4 adopts the burning gases feed mechanism.The burning gases feed mechanism is oxygen cylinder 5 and acetylene cylinder 6.One group of flame gun 4 is constituted single rifle by 2-4.Flame gun 4 adopts the remelting rifle.1 for needing the large-scale workpiece of spraying thermoplastic powder, can be in metal steel structure, pipeline, jar, the groove any one.2 is metal dust, and 12 is air cleaner.
Acting as of each several part in the present embodiment: electrostatic gun: the plastics powder of static electrification is sprayed to workpiece and the plastics powder is adsorbed on the workpiece fully.Flame gun combination: the remelting rifle is converted, realizes that the levelling behind preheating of workpiece and the last powder heats by 2-4.Oxygen cylinder, acetylene cylinder: the energy that the flame gun combined burning is provided.Electrostatic generator: static takes place make molding powder underfill polarity.Powder feeding pump: the principle of utilizing injector with the sucking-off of plastics powder, send in the electrostatic gun.Powder feeding tube: storage plastics powder.Air compressor: the medium of powder feed system powder conveying and the source of the gas of tube cell boiling tube are provided.Air cleaner: remove oil and moisture content in the compressed air.Boiling tube: the plastics powder in the powder feeding tube is seethed so that powder feeding pump sucks the plastics powder.
