Description
Technical field
The present invention relates to a kind of powder spray technical field, more particularly to a kind of Cyclonic negative pressure powder pump.
Background technology
Enterprise is when carrying out powder spray production, it is often necessary to when changing the powder of different colours, and changing powder, it is necessary to
First clean out and accumulate in after the powder in hopper cavity volume and in powder pump cavity volume, can just be put into the powder of another color.
But existing powder pump configuration is relative complex, its internal cleaning dead angle is more, cause workman when clearing up powder not
It is enough convenient, and clear up not clean enough, there is mixed color phenomenon in spraying production, be that the manufacturing of enterprise is brought to a certain degree
Trouble.On the other hand,, can be in material when air-flow enters wheel cylinder from top to down because hopper is generally in up big and down small funnel-form
The air-flow of rotation is formed in bucket, and existing powder pump is generally disposed at the center of feed hopper bottom, air-flow enters feed hopper bottom
Shi Rongyi formation sinuous flows, cause powder to occur frictional heat with inner-walls of duct and the phenomenon of powder solidification occur.
The content of the invention
It is an object of the invention to provide a kind of Cyclonic negative pressure powder pump, the powder pump it is simple in construction, it is internal without powder cleaning
Dead angle, its accumulated powder is easily cleaned, while friction of the powder to inner-walls of duct can be reduced, it is to avoid occur showing for powder solidification
As.
To achieve these goals, the technical scheme is that：
A kind of Cyclonic negative pressure powder pump, it includes：Connecting tube, the level of the outside hopper of top connection are embedded in the connection
Powder pump support, jet pipe and flour extraction pipe on the wall of pipe side；
The powder pump support is a straight tube, and being disposed with jet pipe along the flow direction of the gas in its pipe fixes
Hole, negative pressure hole and flour extraction pipe fixing hole；
The powder pump support is provided with to connect the breach of the negative pressure hole and connecting tube cavity volume, its shape and the company
The shape of nozzle inner wall is adapted；
The jet pipe includes：Tube head and jet needle tubing；
The jet needle tubing is arranged in the jet pipe fixing hole and inserted in the negative pressure hole, and the tube head is high with outside
Pressurized air source is connected, and the high-speed gas that the jet needle tubing sprays are passed through at the negative pressure hole, flour extraction pipe successively.
More than one group of powder pump support can be set as a kind of specific embodiment, in the connecting tube, jet pipe and go out
Tube cell.
Further, the powder pump support, jet pipe and flour extraction pipe are coaxially disposed.
Further, bore of the bore of the port of export of the jet needle tubing than the arrival end of the jet needle tubing
It is small.
Further, the flour extraction pipe is in horn-like close to one end of jet pipe, and the bore edge at the end is remote described
The direction of jet pipe is gradually reduced.
Further, the flour extraction pipe uses surface smooth and not bread material is made.
Further, the powder pump also includes：For the tower joint being connected with outside dusting device, its be sheathed on it is described go out
On the outside of tube cell.
Further, the bottom of the connecting tube is provided with to clear up the connection lid of powder, the connection lid
One end is provided with hinge connection with the connecting tube, and its other end is provided with lock with the connecting tube and is connected.
Compared with prior art, the present invention has following technique effect：
The Cyclonic negative pressure powder pump of the present invention is provided with the powder pump support that level is embedded in connection pipe outer wall, the powder pump
Negative pressure hole in support is connected with the cavity volume of connecting tube, and the tube head and flour extraction pipe of jet pipe by jet pipe fixing hole and go out respectively
Tube cell fixing hole is arranged on the outer wall of connecting tube, only in the jet needle tubing insertion negative pressure hole of jet pipe, makes reservation in connecting tube
Space as big as possible, it is to avoid the dead angle of easy accumulated powder is produced in connecting tube.
Meanwhile, high pressure draught is projected from jet needle tubing, sequentially passes through negative pressure hole and flour opening, due to Venturi effect, should
Gas forms negative pressure at negative pressure hole, on the excircle that connecting tube cavity volume is in due to negative pressure hole, and flowed downward from hopper
Gas produces swirling eddy, in the presence of both, also produces swirling eddy in connecting tube, and powder is with flow rotation and tangentially
Direction is transported to destination through flour extraction pipe；Because powder is acted on by the centripetal force of swirling eddy, so as to reduce to pipeline
The friction of inwall, it is to avoid occur the phenomenon for solidifying powder because of frictional heat.
Further, more than one group of powder pump support, jet pipe and flour extraction pipe can be set in the connecting tube, make what powder was exported
Speed can be improved further.
Further, the powder pump support, jet pipe and flour extraction pipe are coaxially disposed, and jet pipe and flour extraction pipe are arranged at described
The two ends of powder pump branch pipe, because its axiality is easier to ensure when same straight tube two ends process perforate, it is to avoid because processing is inclined
Gases at high pressure that are poor and spraying the jet pipe damage flour extraction pipe.
Further, bore of the bore of the port of export of the jet needle tubing than the arrival end of the jet needle tubing
It is small, when the gases at high pressure is sprayed jet pipe because runner narrows and flow velocity is accelerated, increase is produced because of Venturi effect in negative pressure hole
Negative pressure.
Further, the flour extraction pipe is in horn-like close to one end of jet pipe, and the bore edge at the end is remote described
The direction of jet pipe is gradually reduced, and this shape can guide air-flow, as much as possible drawing powder.
Further, the flour extraction pipe uses surface smooth and not bread material is made, and makes powder will not be because being stained with
Become to be difficult to clear up on flour extraction pipe surface.
Further, the powder pump also includes：The tower joint on the outside of the flour extraction pipe is sheathed on, tower joint uses standard
The joint of system, is connected with outside dusting device using the accessory of standard, adds the applicability of this powder pump.
Further, the bottom of the connecting tube is provided with to clear up the connection lid of powder, the connection lid
One end is provided with hinge connection with the connecting tube, and its other end is provided with lock with the connecting tube and is connected；During normal production,
The connecting tube cover locking prevents powder from falling from connecting tube, when changing the powder of different colours, and opening connection lid can be quick
The accumulated powder cleared up in pipe.
In order to more fully understand and implement, the invention will now be described in detail with reference to the accompanying drawings.
