Description

Derect injection type abrasive fluidic continuous feeding device

The utility model relates to a kind of direct injection abradant jet, be used to clean or the feeding abrasive material device of cutting mechanics.It can supportingly be used for the equipment for jet-stream cleaning abrasive and the cutting work of all trades and professions.

The abradant jet feeding device that uses as the experimental rig of Britain hydrodynamics research association and the experimental rig of Chinese Huainan ore deposit institute and the joint study of ore deposit, Jiaozhuo institute, all adopts single jar of front bottom outlet feed and controls the feeding abrasive material amount by gate valve at present.Its shortcoming is: when the front bottom outlet feed of abradant jet feeding device has intermittently in feeder process, directly press knot because of the abrasive material deadweight and locate in the charging aperture, be prone to abrasive material and harden and stop up bottom outlet; The gate valve of amount of abrasive control simultaneously exists then that to demarcate number of times frequent, and the feeding abrasive material amount such as is difficult for directly reading at problem, and single jar of feeding abrasive material loses continuity, causes because of the abrasive material tinning to lengthen working hours, and has directly influenced operating efficiency.

The utility model purpose is exactly for a kind of novel abradant jet continuous feeding device is provided, to overcome existing above-mentioned deficiency in the prior art.

The utility model is by adopting two abrasive cans to take turns feed, side opening feed and rotate the measure control cover by the adjustment handwheel of band scale and control that the mode of metering realizes.When an abrasive can feed job, the spherical stop valve control of another abrasive can utilization unloads and installs new abrasive material additional goes into jar, thereby can guarantee the continuity of system works; The mode of side opening feed is at feed head side-wall hole, makes abrasive material can directly not press knot at the charging hole place because of deadweight, thereby can overcome the defective that abrasive material hardens and stops up; The adjustment metering of feeding abrasive material amount is to be finished by the measure control cover that external diameter and feed head internal diameter fit.Around the control jacket wall, leave the one group of hole that diameter is different that fits with feed head areole, and the scale on each Kong Junyu below handwheel is corresponding, then adjust handwheel and just can change abrasive material import sectional area size, thereby reach the purpose that simply, accurately obtains the feeding abrasive material amount.

Fig. 1 is the utility model structural representation.

Fig. 2 is an A portion enlarged diagram among Fig. 1.

Below in conjunction with accompanying drawing the utility model embodiment concrete structure is elaborated.

As shown in Figure 1, placing the water return pipeline that pipe that identical high pressure resistant abrasive can 1,6 upper end of shape is connected is formed with two symmetries by return pipe 4 respectively behind threeway 36, spherical stop valve 3,5, is for unloading and exhaust before being used to feed.Inlet pipeline is to go into water tube hose 24 by the high pressure that is connected with water pump to be connected to form with the oral siphon 10,20 of spherical stop valve 12,18 and abrasive can 1,6 respectively after threeway 14, and oral siphon 10,20 communicates with the water inlet 29 of the feed head 7 of two abrasive cans respectively again.The compound abrasive output pipe is by being positioned at oral siphon 10, the compound abrasive efferent duct 11 of 20 belows, 19 1 ends link to each other with the compound abrasive delivery outlet 32 of feed head 7 respectively, and the other end is connected through spherical stop valve 13,17 backs and threeway 16 and towards the high-pressure hose 15 of nozzle, in addition, open an aperture by the road 25,23 and spherical stop valve 9 respectively in the lower right of abrasive can 1,6,21 and link to each other with the water inlet pipe 10,20 of feed head 7.

As shown in Figure 2, abrasive can 1, a plinth 33 is respectively welded in 6 bottom, plinth 33 is by 27 sealings of " 0 " type rubber seal with being threaded of feed head 7, feed head 7 is to process the cover tubular with the 45# steel, measure control cover 34 is equipped with in its inside, the external diameter of measure control cover 34 and the internal diameter fit clearance of feed head 7 are 0.01～0.15mm, the toggle of measure control cover 34 and the bottom outlet of feed head 7 are by 35 sealings of " 0 " type rubber seal, the handle lower end utilizes bolt 26 to fix an adjustment handwheel 8 that has a scale, on the sidewall of feed head 7, be drilled with hybrid channel 31, abrasive material inlet 30, with oral siphon 10,20 water inlets that join 29, the compound abrasive delivery outlet 32 that links to each other with the compound abrasive efferent duct, on the perisporium of measure control cover 34, have one group of diameter different and with the abrasive material inlet 30 abrasive material control holes 28 that fit; Abrasive material control hole 28 is corresponding with the scale on adjusting handwheel 8.The indication of feeding abrasive material amount be for stub bar 7 outer surfaces bottom institute carve 22 with relative being as the criterion of adjustment handwheel 8 high scales.

The course of work of the present utility model is: open reinforced seal cover 2, each abrasive can 1, the seal cover 2 that will feed in raw material after feeding in raw material simultaneously in 6 seals, for making abrasive can 1 in running order, open spherical stop valve 3,12,13, water under high pressure by water pump is through 24 threeways 14 of high pressure hose, and behind oral siphon 10, the water inlet 29, a part enters the inner chamber of abrasive can 1 through compound abrasive inlet 30 and amount of abrasive control hole 28; Another part is then through the hybrid channel 31, and through compound abrasive delivery outlet 32, compound abrasive efferent duct 11, spherical stop valve 13, threeway 16, high-pressure water pipe 15 are led to main jet.When return pipe 4 flows out, illustrate that air drains in the abrasive can 1 as water, close spherical stop valve 3 at this moment, open spherical stop valve 9 then, then system can enter operate as normal.Because nozzle operation, so 31 places have produced certain low-pressure area in the hybrid channel, therefore 25 current that enter abrasive can 1 just can enter feed head 7 downwards by the road, through amount of abrasive control hole 28, abrasive material inlet 30 enters hybrid channel 31, because the mobile motion that drives abrasive grain of water, make the abrasive material part fluidization of high-pressure bottle bottom, thereby make abrasive material utilize pressure flow to be transported to hybrid channel 31 uniformly as carrier, and herein with after the pure water of water inlet 29 stream fully mixes by the road 11, spherical stop valve 13, threeway 16 is delivered to nozzle through high-pressure hose 15, and the self-dependent gravity effect of abrasive material in the abrasive can 1 and flow to feed head 7.When the abrasive material in the abrasive can 1 will use up, open spherical stop valve 18, identical with the operating process of abrasive can 1 then, open spherical stop valve 17 successively, 21, make abrasive can 6 beginning feed, close spherical stop valve 9,13 then successively, 12, open spherical stop valve 3 at last again and make the unloading of abrasive can 1 internal pressure, it is reinforced standby to open the seal cover 2 that feeds in raw material, thereby can realize the continuous supply of abrasive material.The control of amount of abrasive is by adjusting handwheel 8 its high scale to be aligned with 22, can obtain certain feeding abrasive material amount.

The utlity model has structure only, easy to operate, uniform feeding, continuously, stablize, be easy to accurate-metering, direct reading advantage, and stopped the blockage problem of abrasive material, realized the requirement of the continuous feeding of system.
