[background technology]
At present, some enterprise is provided with complete tailing-filled station in the mining industry, the function at this complete tailing-filled station be the discarded tailing sandfilling that will produce in the production process to underground goaf, thereby promptly need not take up an area of the stacking tailings, can guarantee again that the face of land does not produce subsides.This filling system adopts full tailings as filler, the technical process of filling is: after the discarded tailing slurry is delivered to the sand storehouse by pipeline, hold full sand storehouse through sedimentation, compressed air sprays air-flow at a high speed by 125 pulping nozzles in the sand storehouse and forms the boiling shape and carry out pulping then, make the homogeneous flow of high concentration on ground and carry the down-hole, and do not dewater in the down-hole.The key of this technology is the pulping quality in the sand storehouse, the height of the stability of nozzle operation and reliability decision pulping quality.
Existing pulping nozzle adopts the integrated structure of plunger and valve body, by jet break-make on the application valve body that moves up and down of plunger in valve body.Pour in down a chimney in order to prevent that mortar from refluxing, prior art adopts plunger surface and closely cooperating of body cavity wall to finish.At work, plunger very easily jam lost efficacy, and caused the pulping system of calming the anger to break down, and then influence the pulping quality, cause stowing gradient low, regularly cause 30% nozzle to lose efficacy can not to work, its pulping pipeline of calming the anger also can not cause the mortar pipeline blockage by return because of the nozzle plunger jam.Be not in full use owing to above some reason causes the usefulness of Filling Station, need often maintenance.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of number of times that significantly reduces nozzle and pipeline blockage, the time that reduces maintenance and change, the high speed pulping nozzle of raising system job rate and charging quantity.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of high speed pulping nozzle, comprise valve body, valve rod, valve seat and spring, described spring housing is on described valve rod, described valve body is a hollow cylinder shape, inner chamber with an opening, one end of described valve body prolongs the circumference of valve body and evenly offers a plurality of ventholes, described venthole is communicated with section at the bottom of the inner chamber, described valve rod is placed on body cavity, one rectifies facing to the body cavity bottom, other end rivet holder is on valve seat, and an end of described valve seat contact valve rod also is contained in body cavity.
The venthole that it is 3mm that the circumference that one end of described valve body prolongs valve body is evenly offered 8 diameters.
The axes intersect of described venthole is in a bit, and this point is positioned on the axis of inner chamber.
Described valve rod comprises integrated guide post and throw-out lever, the end diameter that described throw-out lever is connected with guide post is greater than the diameter of guide post, the other end of throw-out lever becomes the conical surface, described spring housing is on the guide post of valve rod, described guide post is towards the bottom of inner chamber, and described thrust pole socket is on described valve seat.
Described conical surface angle is 45 °, precision
One end of described valve seat contact valve rod and valve body are by screwed connection.
Described valve seat is by precision
Conical valve seat is formed.
The advantage of the utility model high speed pulping nozzle is: (1) has significantly reduced the number of times of nozzle and pipeline blockage, reduces the number of times of repair time and replacing, has improved system job rate and charging quantity; (2) stable state retrofilling concentration is brought up to now 72% by former 65%, and stowing gradient reaches 9, two indexs and is leading domestic index; (3) cost of manufacture reduces, former employing stainless steel, and existing high speed pulping nozzle can adopt common Q 235-A material, and cost of manufacture reduces greatly.
