Hose；The shot-peening tank is made of upper storehouse and lower storehouse, and the upper storehouse of shot-peening tank controls ball by entrance pellet control valve into ball mouth
The whereabouts of material, and be sealed by upper storehouse end socket；Separated between the upper storehouse and lower storehouse by arc closing surface, upper storehouse and lower storehouse
It is sealed by the lower storehouse end socket for being installed on arc closing surface center of the third solenoid valve control by being connected with controller；Institute
It states to be connected in the outlet gas circuit of compressed gas source and mixes the air inlet switch of ball valve with pneumatic control so that controlling spray gun is by controlling
The 5th solenoid valve of no shot-peening being connected with controller, and control with pneumatic control mix ball valve open close pellet outflow with control
The 4th connected solenoid valve of device processed.
The switch of entrance pellet control valve described in above-mentioned technical proposal is connected by the first solenoid valve being connected with controller
It is connected to compressed gas source.
The level-sensing device being connected with controller is installed on the bulkhead in lower storehouse described in above-mentioned technical proposal；The upper storehouse end socket is logical
The second solenoid valve being connected with controller is crossed to be sealed.
After adopting the above technical scheme, the utility model have the effect of it is following positive:
(1) the utility model is simple and compact for structure, can be not only used for the manual shot-peening operation of workpiece surface, it can also be used to automatic
The continuous shot-peening operation of networked control systems, shot blasting effect is good, easy for installation.
(13) level-sensing device being connected with controller is installed on the bulkhead in the lower storehouse of the utility model；The upper storehouse end socket is logical
It crosses the second solenoid valve being connected with controller to be sealed, when level-sensing device senses lower storehouse pellet deficiency, in solenoid valve control
Storehouse end socket closes, and opens with the sale monopoly storefront of storehouse at present, is flowed into lower storehouse to close the pellet in storehouse, since the amount that entrance pellet flows into is remote
Much larger than the pellet amount sprayed from spray gun, in this way to realize uninterrupted continuous shot-peening operation.
Detailed description of the invention
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein
Fig. 1 is the structural schematic diagram of the utility model；
Numbering in the drawing are as follows:
Specific embodiment
(embodiment 1)
See that Fig. 1, the utility model have shot-peening tank 14, spray gun 13 and compressed gas source 15；Ball mouth company is brought out under shot-peening tank 14
It is connected to band pneumatic control and mixes ball valve 11；It is mixed with pneumatic control and is connected with shot-peening hose 12 between the outlet of ball valve 11 and spray gun 13；
Access enters shot-peening hose 12 after mixing with the compressed air that pneumatic control mixes ball valve 11 with pellet；It is characterized by: shot-peening tank
14 are made of upper storehouse 7 and lower storehouse 9, and the upper storehouse 7 of shot-peening tank 14 is controlled under pellet into ball mouth by entrance pellet control valve 17
It falls, and is sealed by upper storehouse end socket 6；Separated between upper storehouse 7 and lower storehouse 9 by arc closing surface 16, upper storehouse 7 and lower storehouse 9 by
It is sealed by the lower storehouse end socket 8 for being installed on 16 center of arc closing surface that the third solenoid valve 3 being connected with controller controls；
It is connected in the outlet gas circuit of compressed gas source 15 and mixes the air inlet switch of ball valve 11 with pneumatic control by controlling to control spray gun
13 whether the 5th solenoid valve 5 of shot-peening being connected with controller, and control band pneumatic control mix ball valve 11 open close pellet stream
The 4th solenoid valve 4 being connected with controller out.The switch of entrance pellet control valve 17 by be connected with controller first
Solenoid valve 1 is connected to compressed gas source 15.The level-sensing device 10 being connected with controller is installed on the bulkhead in lower storehouse 9；Upper storehouse end socket 6 is logical
The second solenoid valve 2 being connected with controller is crossed to be sealed.
The working principle of the utility model are as follows: 7 upper end of shot-peening tank upper storehouse controls pellet by entrance pellet control valve 17
Whereabouts, be sealed by stopping storehouse end socket 6, upper storehouse 7 and lower storehouse 9 are sealed by the lower storehouse end socket 8 controlled by solenoid valve 3,
To ensure 14 good seal of shot-peening tank.Lower storehouse 9 goes out the mixed ball valve 11 of ball mouth connecting band pneumatic control, the controllable mixed ball of solenoid valve 5
The air inlet switch of valve 11.
When shot-peening, the opening of lower storehouse end socket 8 makes pellet enter lower storehouse, and the mixed ball valve 1 of the control band pneumatic control of solenoid valve 4, which is opened, to be closed
Pellet outflow, the compressed air that solenoid valve 5 controls, which passes through band pneumatic control, which mixes, can cross shot-peening hose 12 after ball valve 1 is mixed with pellet
It most sprays afterwards through storehouse 13 to workpiece surface, to achieve the purpose that workpiece surface is cleared up.Upper storehouse end socket 6 and entrance pellet simultaneously
Control valve 17, which is opened, closes pellet full of upper storehouse.When level-sensing device 10 senses lower storehouse pellet deficiency, solenoid valve 2 controls upper storehouse envelope
First 6 close, and open with storehouse end socket 8 at present, are flowed into lower storehouse 9 to close the pellet in storehouse 7, since the amount that entrance pellet flows into is much big
In the pellet amount sprayed from spray gun 13, in this way to realize uninterrupted continuous shot-peening operation.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
Step is described in detail, it should be understood that being not limited to this foregoing is merely specific embodiment of the utility model
