The pressurized-jet powder supply system disclosed by the invention can provide convenience for activity and maintenance of a welder operator and can ensure the life of a welding wheel and the rigidity of a welding arm.
Description
Technical field
The present invention relates to a kind of powder spraying system, relate more specifically to a kind of boosting jet powder-supply system.
Background technology
In the powder spraying system of system jar industry, adopt venturi ejector principle confession powder under the normal pressure basically.Because tube cell receives the restriction of machine installing space, diameter is little, and the resistance of ducting is big, must be contained in from the nearest position of welding machine for the powder machine, otherwise the powder amount is not enough, influences the coating quality.This installation site influences welding machine operative employee's the activity convenience and the convenience of maintenance.
In addition,, must use 45 millimeters to weld the tube cell that arm just can have enough space mounting 7-8 millimeters down, can influence the life-span of weldering wheel and the rigidity of weldering arm like this for the high speed welding machine of 52 millimeters tank diameters.Be coated with if old machine is coated with to disguise by liquid, also will spend to change the powder arm.
Therefore, be necessary to provide a kind of new powder spraying system to overcome above-mentioned defective.
Summary of the invention
The purpose of this invention is to provide a kind of movable and maintenance that can make things convenient for the welding machine operative employee, and can guarantee to weld the life-span of wheel and the boosting jet powder-supply system of the rigidity of weldering arm.
For realizing above-mentioned purpose; The present invention provides a kind of boosting jet powder-supply system, comprises reclaiming the powder bucket and supplying the powder bucket, supplies powder bucket bottom to connect compressed air source; Compressed air source provides fluidized gas to supplying the powder bucket; Supply the powder bucket and reclaim between the powder bucket to be connected with bypass pipe, fluidized gas gets into through bypass pipe and reclaims the powder bucket, and bypass pipe is provided with and makes the control valve that supplies the powder bucket to obtain to stablize malleation.
Preferably, supply the powder bucket to be provided with pressure sensor, pressure sensor connects the PLC controller, and the PLC controller connects the air inlet adjustment valve, and the air inlet adjustment valve is connected compressed air source and supplies between the powder bucket, and the signal controlling end of control valve is connected to the PLC controller.
Preferably, the air inlet adjustment valve is by stepper motor or servo motor driven.
Preferably, reclaim powder bucket inboard and be provided with filter, the outside is provided with anti-blowpipe, and the shower nozzle of anti-blowpipe and filter upper end are relatively.
Preferably, the outside of recovery powder bucket is connected with and reclaims the powder filter.
Preferably, supply the powder bucket to be provided with and supply the powder valve, supply the powder valve to connect injector.
Preferably, reclaim powder bucket and the integrated setting that supplies the powder bucket for pressing stacked on top, and recovery powder bucket bottom is provided with valve.
Compared with prior art; Boosting jet powder-supply system of the present invention is given by compressed air source to supply the powder bucket to infeed fluidized gas owing to supply powder bucket bottom to connect compressed air source, through bypass pipe fluidized gas is excreted to and reclaims the powder bucket; Throughput and fluidization gas through control valve adjusting bypass pipe makes confession powder bucket obtain malleation again; Make to supply the powder bucket to realize that supercharging supplies powder, supply powder apart from increasing, get rid of welder fault to the operative employee and bring convenience thereby can make; Simultaneously, improved powder to air ratio, also can reach the requirement that supplies the powder amount, thereby can guarantee to weld the life-span of wheel and the rigidity of weldering arm with less pipeline.
Through following description and combine accompanying drawing, it is more clear that the present invention will become, and these accompanying drawings are used to explain embodiments of the invention.
Description of drawings
Fig. 1 is the sketch map of boosting jet powder-supply system of the present invention.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, the similar elements label is represented similar elements in the accompanying drawing.
Please refer to Fig. 1, described boosting jet powder-supply system comprises and is the recovery powder bucket 1 that piles up setting up and down and supplies powder bucket 2, valve 3 and compressed air source.
Valve 3 is located at the bottom of reclaiming powder bucket 1, and is positioned at confession powder bucket 2 inboards, is used to make and reclaims powder bucket 1 and supply powder bucket 2 isolated; Valve 3 is air bag valve or electric gate valve, and can often open also can be normally closed, and it is opened and close through compressed air control; After valve 3 is opened; The powder that reclaims in the powder bucket 1 is fallen in the confession powder bucket 2 through the self gravitation effect, has avoided using the suction injection apparatus, thereby can save fluidized gas and spray powder feeding gas.
Compressed air source provides fluidized gas to supplying powder bucket 2; The aperture of fluidized gas process fluidisation plate is to carry out fluidisation to the powder in the confession powder bucket 2, and fluidized gas is excreted to through bypass pipe 8 and reclaims in the powder bucket 1 afterwards, passes through the throughput and the fluidization gas of control valve 7 adjusting bypass pipes 8 again; Make and supply powder bucket 2 to change supercharging into by normal pressure; Through injector ejection, realize that supercharging supplies powder again, the pressure that supplies powder bucket 2 is to be obtained by coordinated balance between the exhaust resistance of the supply gas pressure of fluidized gas and flow, bypass pipe 8.Owing to supply the supercharging of powder bucket 2, supply the powder distance to strengthen, pipeline can be crooked.This installation site that just is coated with machine to powder provides more flexibly to be selected.Leave suitably distance installation of welding machine to the powder machine, get rid of welder fault to the operative employee and bring convenience.Simultaneously,, improved powder to air ratio, also can reach the requirement that supplies the powder amount with less pipeline owing to supply the supercharging of powder bucket 2.Solved the installing space problem of weldering arm.Because it is little to supply the diameter of tube cell to change, the tube cell that makes 52 millimeters following weldering arm install 5 millimeters becomes possibility.The jar of producing 52 millimeters just need not change 45 millimeters weldering arm, need not use 45 millimeters weldering wheel.Avoided because problems such as the rigidity reduction that 45 millimeters welderings of use arms cause and the weldering wheel losts of life.Be coated with the old machine that is coated with of disguising for liquid, the weldering arm of also need not spending to change.
As stated,, give through fluidized gas to supply 2 superchargings of powder bucket, supply powder apart from increasing, get rid of welder fault to the operative employee and bring convenience thereby can make owing to supply powder bucket 2 to connect compressed air source; Simultaneously, improved powder to air ratio, also can reach the requirement that supplies the powder amount, thereby can guarantee to weld the life-span of wheel and the rigidity of weldering arm with less pipeline.
Invention has been described more than to combine most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
