A kind of granular material air injection equipment, comprise buffer bin 11, the hopper 13 that is communicated with buffer bin 11, it is characterized in that being provided with abrasive material propeller 313 in the exit of hopper 13, this abrasive material propeller 313 is provided with feeding mouth 3133 and discharging opening 3136, the feeding mouth 3133 of abrasive material propeller 313 is communicated with hopper 13, the discharging opening 3136 of abrasive material propeller 313 is communicated with an end of material spray flexible pipe 306, one end of this material spray flexible pipe 306 also is communicated with air inlet pipe 110, the other end of this material spray flexible pipe 306 is connected with feed nozzle 318, wherein abrasive material propeller 313 comprises abrasive material propeller housing 3131, be provided with spiral compression spring 3132 in the abrasive material propeller housing 3131, one end of spiral compression spring 3132 is connected with the output shaft of propulsion motor 301, abrasive material propeller housing 3131 is provided with feeding mouth 3133 near an end of air motor 301, and the other end of abrasive material propeller housing 3131 is provided with discharging opening 3136.Between the feeding mouth 3133 of hopper 13 and abrasive material propeller 313, be provided with manual abrasive material valve 312.
Material spray flexible pipe 306 is connected with nozzle carrier 317, and nozzle carrier 317 is connected with feed nozzle 318, and nozzle carrier 318 is connected with an end of supplementary pressure pipe 207, and the other end of supplementary pressure pipe 207 is communicated with air inlet pipe 110.Output at feed nozzle 318 is provided with synergy pipe 319, this synergy pipe 319 is one columnar structured, and the one end is connected with feed nozzle 318, and the other end is unsettled, inwall at this synergy pipe 319 is provided with two synergy pipe annulus 320, and the outer ring of this synergy pipe annulus 320 is connected with the inwall of synergy pipe 319.
During use, material spray operating personnel press the switch of pneumatic remote-control device 219 to feed nozzle 318 alignment pieces, send the gas circuit signal that material spray begins.Gas control three position five-way valve 204 receives remote signal, open closed type gas control angle valve 101, source of the gas from air inlet pipe 110 is distinguished three directions in the same way by four-way 114: the pressure regulation oil water separator 205 of leading up to leads to propulsion motor 301, and motor 301 drives propellers 313 abrasive material is transported to skew T 314; The second the tunnel directly comes skew T 314 by material spray air inlet pipe 111, and abrasive material is transported to feed nozzle 318, and material spray begins; Third Road is directly delivered to nozzle carrier 317 by replenishing pressure inlet 207 with source of the gas, improves effective operating pressure.
The present invention has installed abrasive material propeller 313 in the exit of hopper 13, and its effect is that rotation is delivered in the skew T 314 by spring spiro rod abrasive material, mixes with Compressed Gas.Because granular material air injection equipment is the pressured gas work of contracting, so abrasive material mixes the pressure that the thrust that need be subjected to is greater than gas with Compressed Gas, the present invention adopts the spiral thrust of spiral compression spring 3132, abrasive material closely is pushed into contracting of propeller 313 receives discharging opening 3136, because abrasive material is closely blocked the discharging opening 3136 of abrasive material propeller 313, played sealing function, made that the Compressed Gas in the skew T 314 can not be revealed in abrasive material propeller 313.When the angle of rake thrust of abrasive material during greater than gas pressure, abrasive material just travels forward, and receives discharging opening 3136 because abrasive material constantly is pushed to contract, so abrasive material just constantly enters in the skew T 314, makes the operation of pressure material spray to carry out continuously.Owing to adopt spiral compression spring 3132 to replace normally used screw rod, its advantage is that spring is telescopic, spring is automatic spacing owing to the density of abrasive material, has avoided being blocked motionless possibility because of rigidity makes screw rod by abrasive material, has improved functional reliability.In addition, the non-rigid matter of spring, it is minimum to make that violent wearing and tearing drop to, and has improved angle of rake service life.In addition spring to change convenient also be a big advantage.Because load is by the rotary speed decision of spiral compression spring 3132 in the abrasive material propeller 313, and the rotary speed of spiral compression spring 3132 is by the torsion decision of propulsion motor, torsion is controlled by the size of bleed pressure, so just can control the size of load by regulating pressure regulation oil water separator 205, therefore by watching motor pressure table 203 to regulate pressure regulation oil water separator 205, can easily control the load size very intuitively, thereby make material spray efficient reach optimum state.
Because when air and abrasive material flow in material spray flexible pipe 306, can make the pressure loss at nozzle carrier 317 places because of friction, pipe is long more also will be big more, the every reduction of effective pressure 0.01MPa, efficient will reduce 2%.Because effective pressure directly influences the efficient of material spray, therefore improve effective pressure and be and improve one of the most direct method of material spray efficient.Adopt the way of introducing supplementary pressure pipe 207 in the present invention, make effective pressure maximize.Between nozzle carrier 317 and feed nozzle 318, be provided with pipe joint 316, sidewall at this pipe joint 316 is provided with slant notch 3161, this slant notch 3161 along nozzle carrier 317 to feed nozzle 318 direction extend to inwall by outer wall, these slant notch 3,161 one ends are communicated with supplementary pressure pipe 207, and the other end is communicated with feed nozzle 318.Regular meeting causes feed nozzle to stop up during because abrasive material increases suddenly, because of 207 outlets of supplementary pressure pipe are structures of oblique flow, can dredge the abrasive material that concentrates on feed nozzle 318 import departments, makes material spray be not easy to take place the feed nozzle clogging, has improved operating efficiency.Supplementary pressure pipe 207 has been arranged, made reduce relative of air-flow in the material spray flexible pipe 306 can prolong the service life of stuff-spraying pipe, reduced cost with the abrasive material movement velocity.Especially long distance (＞20m) during material spray, supplementary pressure pipe 207 roles are more obvious, the additional material spray efficient that makes of effective pressure improves greatly.Supplementary pressure pipe 207 has been arranged, reached identical effective pressure, material spray flexible pipe 306 can reduce diameter, and the diameter of material spray flexible pipe 306 can be kept to 25mm by original 32mm.Alleviate material spray operating personnel's working strength, and increased the flexibility of material spray, more convenient such as the material spray among a small circle.
Increased a synergy pipe 319 in the exit of feed nozzle 318, its role is to the kinetic energy of outlet air is converted to static energy.There are not feed nozzle 318 exits of synergy pipe 319 to spread suddenly owing to air, air drag increases, make the exit air velocity reduce significantly, the wearing and tearing of the exit of feed nozzle 318 are violent in addition, cause feed nozzle 318 exits wearing and tearing and scrap, after adopting synergy pipe 319 of the present invention, can effectively increase the service life of feed nozzle 318.After synergy pipe 319 had been arranged, air-flow short stay in synergy pipe 319 in feed nozzle 318 exits changed kinetic energy into static energy, made air-flow that abrasive material is impacted by on the cleaning workpiece.The pipe of synergy simultaneously 319 can effectively increase the length of feed nozzle 318, and material spray efficient is increased.Synergy pipe 319 has been avoided the unexpected expansion in feed nozzle 318 exits, avoids producing very strong explosion sound, makes that the speed in exit is faster, reaches supersonic speed, can finely improve the noise pollution of operating personnel and surrounding working environment.
