Abstract
The present invention relates to one kind being used for the internally coated spray equipment of oil tree shaped piece, including lance tube (1), powder tube (2) and impeller (5), described lance tube (1) front end is machined with gun slot, the powder tube (2) is fixed in lance tube (1), its meal outlet extends at gun slot, the impeller (5) is set to gun slot front end, and can be around lance tube (1) axial-rotation.Compared with prior art, the present invention has fully ensured that atomizing effect and spraying effect, drastically reduces doing over again for product and also mitigates the working strength of employee, improves production efficiency, it is sprayed suitable for oil tree shaped piece inner coating, and production efficiency and the first-time qualification rate etc. for improving product.
Description
Technical field
The present invention relates to a kind of spray equipments, are filled for the internally coated spraying of oil tree shaped piece more particularly, to one kind
It sets.
Background technology
It is now domestic increasingly ripe for the various straight tube powder spray technologies of oil drilling rod, oil pipe, delivery pipe etc..
Each elephant reaction needs to carry out powder spray to oil tree shaped piece now, but for being applied in the powder of oil tree shaped piece
The development now of layer spraying technology is not also very ripe, the reason is that shaped piece can not be rotated when powder spray, turning is again too many,
It can not make the uniform coating thickness after spraying and all standing, difficulty of construction is big, and the amount of doing over again is big.Therefore in oil tree shaped piece
Coating spraying becomes the weak link of inner coating production line.
Invention content
It is different for oil tree that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind
The internally coated spray equipment of shape part.
The purpose of the present invention can be achieved through the following technical solutions：
One kind being used for the internally coated spray equipment of oil tree shaped piece, including lance tube, powder tube and impeller, the spray
Gun barrel front end is machined with gun slot, and the powder tube is fixed in lance tube, and meal outlet extends at gun slot, described
Impeller is set to gun slot front end, and can be around lance tube axial-rotation.
As preferred embodiment, the lance tube is the hollow aluminium alloy steel pipe of the external feeder of connection.
As preferred embodiment, the lance tube front end is equipped with fixed seat, and the impeller is set by rotating member
Set in the fixed seat, in fixed seat trepanning formed lance tube nozzle, the powder tube pass through the fixed seat, and with
The gun slot crosses.
As further preferred embodiment, the rotating member includes bearing, shaft and nut, wherein described
Bearing is fixed in the fixed seat, and the shaft stretches into fixed seat, and is rotatablely connected with the bearing, described
Impeller is mounted in the shaft, and is fixed by the nut.
As further preferred embodiment it is further preferred that the rear and front end of the bearing is equipped with end ring,
The end ring is set in the shaft.
As further preferred embodiment, the fixed seat is connect with lance tube screw-thread fit.
Compared with prior art, the present invention has the following advantages：
(1) by the way that impeller is arranged in lance tube front end, in spraying, impeller can revolve at a high speed under pressure-air effect
Turn, so that the powder atomization blowed, and under the rotation diffusion of impeller so that atomizing concentration is in certain space range
It is interior to remain uniform, it has fully ensured that atomizing effect and even application effect, has drastically reduced the person of also mitigating that does over again of product
The working strength of work, improves production efficiency.
(2) it is suitable for oil tree shaped piece inner coating to spray, and improves the production efficiency and first-time qualification rate of product.
