Description
Technical field
The utility model patent relates to a kind of filling device of emulsion, relates in particular to a kind ofly to be used to prevent that blast hole charging emulsion upwards from returning the device of medicine.
Background technology
In the charging of mine, down-hole, there is part big gun hole to be the hole that makes progress, therefore in powder charge process, fall because of the deadweight returning charge for preventing explosive, need carry out plug-hole to the big gun hole.The quick-fried industry of people down-hole powder charge at present both at home and abroad is mainly with downward hole or tiltedly go up Kong Weizhu, and tiltedly goes up the hole and limited by explosive viscosity and transporting resistance, is shallow bore hole mostly, and is main with artificial drug delivery how.Along with technological progress, the on-site mixed car of emulsion begins to come into operation at some large-scale mines, but also only is confined to downward hole and tiltedly goes up the hole, and tiltedly to go up the hole be main with manually-operated still, still can't resolve the returning charge problem in the hole that makes progress.Above-mentioned working method efficiency is low, and labor strength is big, and the work on the spot environment is abominable, has open defect.
Summary of the invention
The purpose of the utility model is to overcome the defective in the above technology, provide a kind of rational in infrastructure, sealing is reliable, can prevent effectively that blast hole charging emulsion upwards from returning the device of medicine.
Be to realize above-mentioned purpose, the technical scheme that the utility model adopts is: a kind ofly be used to prevent that blast hole charging emulsion upwards from returning the device of medicine, comprise cavity, safety disc, rubber sleeve, unidirectional rubber ring, seal receptacle, cone shaped one-way valve.The outside of said cavity is provided with rubber sleeve, and the inner chamber of cavity is provided with unidirectional rubber ring, and the cavity upper end is provided with seal receptacle, between said seal receptacle and cavity safety disc is installed, and said seal receptacle top is provided with cone shaped one-way valve.
Further, connect with soket head cap screw between said cavity and the said seal receptacle.
Further, on the said seal receptacle guide post is installed, said guide post becomes to be slidingly connected with cone shaped one-way valve through cone shaped one-way valve.
Further, the two ends of said rubber sleeve are provided with fixed cover.
Operation principle of the present invention is following: the inner chamber of medicine-feeding rubber pipe and cavity of the present invention is linked to each other, and send into big gun hole assigned address.After arriving assigned address, utilize medicine-feeding rubber pipe to begin to carry emulsion, do not open because of the safety disc of anti-material-returning device, emulsion forms pressure in cavity; Unidirectional rubber ring is washed open, and emulsion gets in the rubber sleeve, and rubber sleeve receives compression swelling; With clearance seal between cavity and big gun hole, when pressure reached design load, safety disc was destroyed; Emulsion backs down cone shaped one-way valve, gets into the big gun hole and begins dynamite charge, after powder charge finishes; Cone shaped one-way valve moves downward under the pressure effect of big gun hole internal emulsification explosive, with the cavity bore seal, prevents to load back emulsion medicine because of the returning charge of deadweight whereabouts thereby reach.
Compared with prior art; The advantage of the utility model is: being used to of the utility model prevents that blast hole charging emulsion upwards from returning the device of medicine; Simple and compact for structure, with low cost, easy for installation, sealing is reliable; Can be applicable to deep hole, mechanized charging, greatly reduce working strength of workers, improve loading rate.In powder charge process, ground does not have matrix and falls down, and operating environment is good, and is pollution-free.The present invention is applied to upward hole emulsion loading system, has fundamentally solved the problem of returning charge, has greatly reduced working strength of workers, has improved operating efficiency, and has realized complete mechanicalization, the automation of powder charge process.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model.
In the accompanying drawing: 1-cavity, 2-safety disc, 3-rubber sleeve, 4-unidirectional rubber ring, 5-fixed cover, 6-seal receptacle, 7-cone shaped one-way valve, 8-hexagon socket countersunk flat cap head screw, 9-guide post.
The specific embodiment
Below will combine specific embodiment and Figure of description that the present invention is explained further details.
As shown in Figure 1, a kind ofly be used to prevent that blast hole charging emulsion upwards from returning the device of medicine, comprise cavity 1, safety disc 2, rubber sleeve 3, unidirectional rubber ring 4, fixed cover 5, seal receptacle 6, cone shaped one-way valve 7, hexagon socket countersunk flat cap head screw 8 and guide post 9.
Said cavity 1 is the part of the force of this device, and other part all is attached on the cavity; Said safety disc 2 is located at the upper end of cavity 1; Be used to guarantee the emulsion pressure in the rubber sleeve 3; Thereby guarantee the pressure of the frictional force in rubber sleeve outer surface and big gun hole greater than the top emulsion, the pressure effect of emulsion is not mobile down up thereby guarantee it; Said rubber sleeve 3 is located at cavity 1 outside, and rubber sleeve can receive compression swelling after pouring emulsion, is used for clearance seal between check-valves and big gun hole; Said unidirectional rubber ring 4 is located in the cannelure of cavity 1, is used in the unidirectional entering rubber sleeve 3 of emulsion with pressure; Said fixed cover 5 is located at the two ends of rubber sleeve 3, is used for rubber sleeve 3 sealings reliably, in order to avoid emulsion is revealed, causes rubber sleeve 3 pressure to descend; Said seal receptacle 6 is located at cavity 1 upper end, is used for fixing safety disc 2 and links cone shaped one-way valve 7; Said cone shaped one-way valve 7 is located at seal receptacle 6 tops, is used for the inner chamber of seal chamber 1; Said hexagon socket countersunk flat cap head screw 8 is used to link fixing seal seat 6 and cavity 1; Said guide post 9 is used for the spacing of cone shaped one-way valve 7.
As shown in Figure 1, during use, the inner chamber of the cavity 1 of medicine-feeding rubber pipe and the utility model is linked to each other, and send into big gun hole assigned address.After arriving assigned address, utilize medicine-feeding rubber pipe to begin to carry emulsion, because of the safety disc 2 of anti-material-returning device is not opened; Emulsion forms pressure in cavity 1, unidirectional rubber ring 4 is washed open, and emulsion gets in the rubber sleeve 3; Rubber sleeve 3 receives compression swelling, with clearance seal between cavity 1 and big gun hole; When pressure reached design load, safety disc 2 was destroyed, and emulsion backs down cone shaped one-way valve 7, got into the big gun hole and began dynamite charge; After powder charge finished, cone shaped one-way valve 7 moved downward under the pressure effect of big gun hole internal emulsification explosive, with cavity 1 bore seal.
