Abstract
The utility model discloses a kind of tailing-filled Anti-clogging spray nozzle, by housing, interior air chamber, outer air chamber, shower nozzle, venthole (more than 2), formed, interior air chamber, outer air chamber are in housing, venthole is opened on shower nozzle, venthole one end is communicated with outer air chamber, the other end is communicated with outside, on described shower nozzle venthole, spring-backed quill is set.When unlatching is calmed the anger, calm the anger and enter interior air chamber, rely on pressure to wash the scarfing of scarfing pad open, calm the anger and enter outer air chamber, then enter venthole, rely on pressure to make wrapping tightly the spring-backed quill distending of shower nozzle, calm the anger from the gap ejection of spring-backed quill and shower nozzle.Now, due to the stable supplying of calming the anger, last mortar can not enter from gap venthole inside; When closing while calming the anger, in nozzle, gas pressure disappears, and the spring-backed quill of distending restores to the original state rapidly, tightly encases shower nozzle, mortar and venthole are isolated, thereby it is anti-blocking to realize first, and when tailing-filled, fine grained can not enter venthole, plug nozzle.
Description
Technical field
The utility model relates to mining machinery field, specifically refers to a kind of tailing-filled Anti-clogging spray nozzle.
Background technology
Tailing-filled classical technique is that the low concentration last mortar of ore dressing discharge is delivered in Filling Station sand storehouse, and low concentration mortar is natural subsidence in sand storehouse, after sedimentation, discharges clear water more than sand face, and the last mortar concentration in sand storehouse is improved.During filling, by the sandpipe last mortar of putting bottom sand storehouse, certainly flow into mixing plant, for making bottom, sand storehouse high-concentration mortar present fluidization, bottom, sand storehouse needs to arrange compressed air piping, by nozzle, spray compressed air, bottom, sand storehouse mortar is become flexible and present fluidization, so that smooth and easy outflow sand storehouse.Sand storehouse bottom nozzle is arranged by certain density, generally arranges hundreds of.The anti-blocking principle of conventional spout is mainly by calming the anger and telescopic spring shower nozzle, opens that spring is compressed when calming the anger, and shower nozzle stretches out, and due to the outwards ejection of calming the anger constantly, venthole is now difficult for being blocked.When calming the anger, close spring and recover, shower nozzle is retracted in housing, isolated with mortar, plays anti-blocking effect.But because tailings particle is superfine ,-20 microns of content are more than 30%, and the machining accuracy of nozzle is limited, long-term and mortar friction, causes shower nozzle and housing to have certain interval in addition, and fine grained tailings very easily enters gap, while causing shower nozzle retraction, is stuck, and cannot bounce back.Thereby cause fine grained to enter in a large number nozzle from spray orifice, plug nozzle, even causes a large amount of tailings to enter in compressed air line, cause air pipe to stop up, thereby large flow nozzle lost efficacy in sand storehouse, caused whole tailings storehouse tailings to discharge when serious, have a strong impact on filling in mine and produce.The frequent nozzle of changing, dredging compressed air line, in maintenance sand storehouse, facility cost is high, difficulty is large, the time is long, and benefit greatly reduces.
Utility model content
The utility model object is to provide that a kind of tailings can plug nozzle when tailing-filled, and tailings can not enter in compressed air line yet, the tailing-filled Anti-clogging spray nozzle that causes air pipe to stop up.Do not need often to change nozzle, dredging compressed air line, has reduced cost, has improved productivity effect.
The utility model object is to realize like this, this tailing-filled Anti-clogging spray nozzle, by housing, interior air chamber, outer air chamber, shower nozzle, venthole (more than 2), formed, interior air chamber, outer air chamber are in housing, venthole is opened on shower nozzle, venthole one end is communicated with outer air chamber, the other end is communicated with outside, on described shower nozzle venthole, spring-backed quill is set.
Between described interior air chamber, outer air chamber, be provided with scarfing pad.
Described venthole and horizontal sextant angle 15o< β <45o.
Owing to spring-backed quill being set on described shower nozzle venthole, spring-backed quill is tightly wrapped in shower nozzle venthole, and is fixed on nozzle body by fixture.When unlatching is calmed the anger, calm the anger and enter interior air chamber, rely on pressure to wash the scarfing of scarfing pad open, calm the anger and enter outer air chamber, then enter venthole, rely on pressure to make wrapping tightly the spring-backed quill distending of shower nozzle, calm the anger from the gap ejection of spring-backed quill and shower nozzle.Now, due to the stable supplying of calming the anger, last mortar can not enter from gap venthole inside; When closing while calming the anger, in nozzle, gas pressure disappears, and the spring-backed quill of distending restores to the original state rapidly, tightly encases shower nozzle, mortar and venthole are isolated, thereby it is anti-blocking to realize first, and when tailing-filled, fine grained can not enter venthole, plug nozzle.
When occurring that spring-backed quill recovers not in time, or there is fine gap in spring-backed quill and shower nozzle, while causing a small amount of fine grained to enter venthole and outer air chamber, scarfing pad enters interior air chamber by prevention fine sand and avoids stopping up compressed air line, while reopening when calming the anger, a small amount of fine grained is discharged from outer air chamber with calming the anger, thereby it is anti-blocking to realize second, tailings can not enter in compressed air line yet, causes air pipe to stop up.Do not need often to change nozzle, dredging compressed air line, has reduced cost, has improved productivity effect.
Accompanying drawing explanation:
Fig. 1 is Anti-clogging spray nozzle structural representation;
Fig. 2 is scarfing gasket construction schematic diagram.
The specific embodiment
With reference to figure 1 this tailing-filled Anti-clogging spray nozzle, by more than housing 10, interior air chamber 1, outer air chamber 7, shower nozzle 6, venthole 4(2) form, interior air chamber 1, outer air chamber 7 are in housing 10, venthole 4 is opened on shower nozzle 6, venthole 4 one end are communicated with outer air chamber 7, the other end is communicated with outside, on described shower nozzle venthole 4, spring-backed quill 2 is set, and is fixed on nozzle body 10 by fixture 3.Spring-backed quill 2 can be made with materials such as rubber tube, silicone tubes.
Between described interior air chamber 1, outer air chamber 7, be provided with scarfing pad 8, centre has scarfing 9.
Described venthole 4 and horizontal sextant angle 15o< β <45o, guarantee to calm the anger and discharge smoothly by venthole 4 from outer air chamber.
When unlatching is calmed the anger, calm the anger and enter interior air chamber 1, rely on pressure to wash the scarfing 9 of scarfing pad 8 open, calm the anger and enter outer air chamber 7, enter again venthole 4, rely on pressure to make wrapping tightly spring-backed quill front end 5 distendings of shower nozzle, calm the anger from the gap ejection of spring-backed quill front end 5 and shower nozzle 6.Now, due to the stable supplying of calming the anger, last mortar can not enter nozzle interior from gap; When closing while calming the anger, in nozzle, gas pressure disappears, and the spring-backed quill front end 5 of distending restores to the original state rapidly, tightly encases shower nozzle 6, mortar and venthole 4 are isolated, thereby it is anti-blocking to realize first.
When occurring that spring-backed quill front end 5 recovers not in time, or there is fine gap with shower nozzle 6 in spring-backed quill front end 5, while causing a small amount of fine sand to enter venthole 4 and outer air chamber 7, scarfing pad 8 enters interior air chamber 1 by prevention fine sand and avoids stopping up compressed air line, while reopening when calming the anger, a small amount of fine sand is got rid of from outer air chamber 7 with calming the anger, thereby it is anti-blocking to realize second, and spring-backed quill 2 and scarfing pad 8 form the effect of dual one-way valve.
