Description
Technical field:
This utility model relates to a kind of powder feeding mouth structure, particularly relates to the powder feeding mouth knot of a kind of supersonic spray gun
Structure.
Background technology:
In thermal spraying industry, the powder feeding mouth of fuel combustion type HVAF is typically all two, left and right, actual powder feeding
Time, powder is in the middle of two powder feeding pins radially feeding flame, because the flame stream of flame is circular, and powder feeding mouth is positioned at flame
Two ends, the high-temperature gas produced in flame course of injection does not utilizes cmpletely, and there is a part of flame stream does not has calcination powder
The waste at end, and from the point of view of the microcosmic of the flame ejected, with elliptical shape, there is powder grain and be distributed not in flame speckle
Equal phenomenon.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of supersonic flame
The powder feeding mouth structure of spray gun, it is possible to increase the uniformity of powder feeding, promotes the efficiency of coating processing, effectively saves fuel and people
Work running cost.
This utility model is that the technical scheme solving technical problem to be taken is:
A kind of powder feeding mouth structure of supersonic spray gun, including powder feeding mouth, cylindrical, hollow contiguous block and jet pipe, described
Powder feeding mouth is arranged on cylindrical, hollow contiguous block, and described powder feeding mouth has four, is respectively uniformly distributed in described cylindrical, hollow
On 45 degree, the upper left of contiguous block, upper right 45 degree, 45 degree, lower-left, direction, 45 degree, bottom right, described jet pipe is connected by cylindrical, hollow
Block is connected with combustor.
Described jet pipe is cylindrical jet pipe, and its one end is provided with external screw thread, and the external diameter of described jet pipe is with cylindrical, hollow even
The internal diameter connecing block matches.
Described powder feeding mouth is connected with cylindrical, hollow contiguous block by powder feeding pin, inside described cylindrical, hollow contiguous block
Being provided with female thread, female thread structure matches with the external thread structure on described jet pipe.
Of the present utility model actively provide the benefit that:
1, arranging of four powder feeding mouths of this utility model can make powder have granularity evenly before entering flame time ratio
Distribution, allows the calorific value of flame sufficiently utilize, to realize bigger powder feeding rate.
2, the powder sending quantity in this utility model increases the unit interval also can reach good coating and pile up, thus promotes coating
The efficiency of processing, has been effectively saved fuel and manually-operated cost.
3, this utility model can save the input cost of equipment and manpower, has good economic benefit and practical valency
Value.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the powder feeding mouth structure of a kind of supersonic spray gun of this utility model.
Detailed description of the invention:
The utility model is further explained and explanation with specific embodiment below in conjunction with the accompanying drawings:
See Fig. 1: in figure, 1-powder feeding mouth, 2-cylindrical, hollow contiguous block, 3-powder feeding pin, 4-combustor, 5-jet pipe.
Embodiment: the powder feeding mouth structure of a kind of supersonic spray gun, including powder feeding mouth 1, cylindrical, hollow contiguous block 2 and
Jet pipe 5, powder feeding mouth 1 is arranged on cylindrical, hollow contiguous block 2, and powder feeding mouth 1 has four, is respectively uniformly distributed in described cylinder
On 45 degree, the upper left of hollow contiguous block 2, upper right 45 degree, 45 degree, lower-left, direction, 45 degree, bottom right, jet pipe 5 is by cylindrical, hollow even
Connect block 2 to be connected with combustor 2.
Wherein: jet pipe 5 is cylindrical jet pipe, and its one end is provided with external screw thread, and the external diameter of jet pipe 5 is connected with cylindrical, hollow
The internal diameter of block 2 matches.
Powder feeding mouth 1 is connected with cylindrical, hollow contiguous block 2 by powder feeding pin 3, sets inside cylindrical, hollow contiguous block 2
Being equipped with female thread, female thread structure matches with the external thread structure on jet pipe 5.
During work, by powder from 45 degree, upper left, upper right 45 degree, 45 degree, lower-left, four on the four direction of 45 degree, bottom right are sent
Powder mouth 1 is simultaneously fed into, so, powder when entering flame just can the ratio distribution of particle sizes having before evenly, allow the heat of flame
It is worth to sufficiently utilize.
The above, be only preferred embodiments of the present utility model, this utility model is not made any in form
Restriction, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations with
Modify, all still fall within the protection domain of technical solutions of the utility model.
