Technical field
The utility model relates to anti-corrosion pipeline powder coating and their application technical fields；More particularly to a kind of heavy caliber plastic-coated steel
Fluidized bed coating process device.
Background technique
Statement in this part merely provides background information related with present disclosure, thereby increases and it is possible to not constitute
The prior art.
Fluidized bed painting technique is one of the method more early implemented in powdery paints.The working principle of fluidized bed is with equal
The thin air circulation that dissipates of even distribution crosses fluidized plate, stirs powder particle in gentle boil state, establishes to air-flow and powder flat
Liquid level is maintained at certain altitude after weighing apparatus reaches stable state.After the workpiece that need to be applied preheating, it is put into the powder of boiling, powder heat
Melting, which is adhered on workpiece, obtains uniform coating, finally heated film-forming, coating layer thickness and workpiece preheating temperature and workpiece
The time for immersing fluidized bed is related.China starts to have carried out fluidized bed painting research to powder early in early sixties, and obtains
Success, is mainly used in electronic product at that time, such as the insulating coating and corrosion-inhibiting coating to these cun lesser work to the greatest extent of motor
Deng.But it is applied to heavy caliber plastic-coated steel powder coating not to be reported.This is because the self weight of heavy caliber plastic-coated steel is heavy, volume
Huge, when lifting, needs large-scale hoisting machinery to be operated, in addition, pipeline corrosion protection belongs to heavy anti-corrosion paint field, it is desirable that anti-corrosion
The engineering service life reaches 50 years or more, and the quality of coating is very strict, using common fluidized bed painting it is difficult to ensure that powder coating
Sufficiently solidification, it is difficult to guarantee anticorrosive quality.Therefore heavy caliber plastic-coated steel outer wall powder coating mainly uses a fixed number at present
The electrostatic gun of amount is special on the workpiece of preheating, or through steel pipe top by powder spray by way of electrostatic spraying
Powder sprinkle is kept a period of time curing molding, both mode coatings on steel pipe that is preheated and rotating by coating device
The a large amount of dust from flying of Cheng Zhongyou causes coating process environmental protection to be difficult up to standard, and crosses a large amount of landing powder of spray generation and need to recycle
It returns again in finishing system, increases the labor intensity of coating worker, malfunction is also easy to generate the pollution of recycling powder, band
Carry out hidden danger of quality.
Therefore the prior art has much room for improvement and develops.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of disadvantage to solve existing coating mode, ad hoc meter is special
For heavy caliber plastic-coated steel anti-corrosion fluidized bed powder coating unit.
The technical solution of the utility model is:
A kind of heavy caliber plastic-coated steel fluidized bed coating process device, including the powder slot and underlying air being located above
Slot, is equipped with filter element between air groove and powder slot, powder slot side end is equipped with baffle, the steel pipe to extension is raw
Port is equipped with isolation board, and isolation board is adapted to the radian of steel pipe contact site with the curvature of steel pipe；It is set on steel pipe axial direction
Have and the comparable air groove of length of steel pipe.
It further include the movable support below air groove, the movable support upper-lower height is adjustable.
The filter element is filter cloth.
The material of the baffle is stainless steel.
The utility model has the beneficial effects that
Coating unit using the above structure will not lead to the problem of the powder recycling and reusing again of spray, greatly improve
Coating efficiency of the powdery paints on large-diameter steel pipe, and dust from flying will not be generated in coating process, make coating process
Meet the increasingly strict environmental requirement of today's society.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is air groove partial structural diagram.
Specific embodiment
Embodiment:
Refering to fig. 1 and Fig. 2, the coating unit of the utility model is divided into the top part and the bottom part point；Lower section is air groove 1, top is powder
Last slot 2, centre are separated by filter cloth 3, and the design of 1 surrounding side of powder slot has the outward stainless steel shoe 5 of certain angle, steel pipe
6 ports, which have, detachably reserves port isolation plate 7, and the radian and 6 circumference arc of steel pipe of isolation board 7 are substantially matching.It is axial in steel pipe 6
Tri- air grooves of A, B, C are devised on direction, and provide air quantity by tri- blowers of corresponding A, B, C, and air groove total length omits
Greater than steel pipe overall length, when 6 length of steel pipe changes, it is four or two that 1 quantity of air groove, which can suitably increase and decrease, and coating unit is fixed
It on movable support, can be adjusted up and down in height, the powder being stored in powder slot 2 can be made to avoid the heat of raying far from steel pipe 6
Amount influences to generate clustering phenomena, and ramp rate can be adjusted by decelerating motor 9.Air filter cloth between air groove 1 and powder slot 2
3, permissible air passes through, but powder coating particles cannot pass through.
Concrete operations are as follows:
1, the reserved port isolation plate 7 of corresponding radian is installed according to diameter of steel tube on powder slot 2, equipment is secured in position
Afterwards, powdery paints is fitted into powder slot 2, starts the frequency conversion high pressure blower of air groove 1 after uniformly spreading out, powdery paints starts to flow
Dynamic, powdery paints reaches uniform fluid boiling state after about two minutes, adjusts the height that elevator 4 adjusts fluidized bed, allows
The powder of boiling is higher by two side baffles, 5 bottom 10-15mm.
2,6 speed of rotation of steel pipe on the rotating platform by the steel pipe 6 heated lifting, is adjusted, after steel pipe rotary is stablized,
Adjust coating unit elevator contact the powder of fluid boiling with the steel pipe bottom surface of heating, by control steel pipe bottom with
The time of contact of boiling powder can control the thickness of corrosion-inhibiting coating.Air groove blower is closed after reaching the time, stops the stream of powder
Change, fluidized bed is bottomed out, coating operation is completed, and the fluidized bed coating process operation of next steel pipe is carried out.
The outer wall coating that large-diameter steel pipe is carried out using the fluidized bed that the present invention designs, has the following characteristics that
