The big specification of the secondary pulping of mortar is anti-to bury blocking sprayer

Technical field

The utility model relates to when ore dressing or the secondary pulping of mine sand warehouse sand setting, by water spray by precipitated mortar Re-form the novel spray-head device of transportable mortar.

Background technique

Currently, the secondary pulping of dressing plant's concentrator or mine sand warehouse mortar, in order to by precipitated mortar again shape It at transportable mortar, sprays water, sand setting is washed away to realize by using spray head mostly.But this spray head is stopping After water spray, it is easy to cause spray head to be blocked because the mortar precipitated again enters inside spray head.When it needs to carry out secondary pulping When operation, can not normally it spray water.

Spray head is blocked in order to prevent, and common practice is utilized in the method for the jacketed emulsion tube in spray head front end all to solve Certainly.The problems such as this method is generally only used for the spray head of 6mm or less specification, and it is small that there are yields, pulping low efficiency.For The sand warehouse of complete heap buried, again that mortar emptying is very difficult, generally requiring to devote a tremendous amount of time could dredge with manpower and material resources It is logical.

It is secondary to complete using the polycyclic a large amount of little shower nozzles of setting of multiple spot in order to solve the problems, such as that little shower nozzle yield is small The problems such as pulping, there is also limited spaces, installation complexity.

Utility model content

The purpose of this utility model is to provide for a kind of big specification and big rule can both can be improved to prevent burying stifled spray head The work efficiency of lattice spray head solves sand warehouse by the dredging problem after sand setting heap buried, also can solve and easily block existing for big specification spray head Problem.

Purpose of the utility model is realized as follows: the big specification of the secondary pulping of mortar is anti-to bury blocking sprayer, if the device has Dry pointed nozzle, a center pillar, a cloth water impeller, center pillar are fixed on the center on spray head top, and pointed nozzle is fixed It is arranged in around the center pillar of spray head top, water distribution impeller set is on center pillar and can rotate around center pillar and rise up and down along center pillar Drop.

Further, it is the wheel-like structure cylindrical, lower part is cone that water distribution blade wheel structure, which is a top, and center has one A circular hole passed through for center pillar；Upper cylindrical part is fixedly installed with four leaves for being the ゜ of 30 ゜~60 with center pillar central axes oblique angle Piece.

Further, the cone angle of cloth water impeller lower part is consistent with the oblique angle direction of pointed nozzle, the cloth when stopping water spray It can coincide, automatically can all block jet expansion each other after water impeller decline.

Further, the bore inner diameter of water distribution impeller center is more bigger than the outer diameter of center pillar, it is made to form certain gap each other, So that it smoothly moves up and down and rotates.

It is internal diameter borehole structure more bigger than middle shaft diameter, blade and center pillar on cloth water impeller in the middle part of cloth water impeller Axis has certain oblique angle, when spray head around center pillar water spray, can generate upward and oblique motive force, promotion cloth water impeller around Middle shaft rotation constantly rises along center pillar, and water (flow) direction is made to change.With fairly simple method, solve existing common Spray head is existing to be difficult to pulping or the inefficient problem of pulping after heap buried.

When stopping water spray, cloth water impeller declines naturally due to gravity, along center pillar.Due to cloth water impeller lower part vertebra The angle of body is identical with the angle of the nozzle openning on spray head, drops to cloth water impeller lower cone body and is overlapped with nozzle openning When, the nozzle of its underpart is all blocked automatically.After spray head stops water spray, the mortar precipitated again inside sand warehouse enters spray head Internal approach is blocked, and eliminates the possibility that spray head is blocked by mortar.

The center pillar for being mounted on spray head center is an elongated solid round rod, is in the rotation of cone-shaped cloth water impeller The guide rail of axis and cloth water impeller raising and lowering.Cloth water impeller therefrom go out by column top in order to prevent, capital in this End should install limited screw device.

The main body of cloth water impeller is the wheel-like structure that a top is garden cylindricality, lower part is cone, and center has one The circular hole passed through for center pillar.Upper cylindrical part is fixedly installed with four blades that a fixed inclination is formed with center pillar central axes. When the current scour that these blades are gone out by the nozzle parallel with center pillar axis, upward and slanting promotion can be generated Power, makes cloth water impeller around center pillar middle shaft rotation, constantly rises along center pillar, and water (flow) direction is made to change.Under cloth water impeller Portion's setting is conical, and the water flow for being on the one hand to that spray head is facilitated to spray smoothly is gone out upwards, rotates cloth water impeller smoothly And rising, it is often more important that after spray head stops spraying water, upward and slanting motive force suffered by cloth water impeller all disappears, Due to the effect of gravity, cloth water impeller drops to naturally when being overlapped with the nozzle openning being mounted on around center pillar, can be by these Nozzle openning blocks completely, the mortar precipitated again is not allowed inside sand warehouse to enter nozzle interior, and reaching prevents nozzle to be blocked Purpose.In order to ensure this plugging effect, the oblique angle requirement of the cone angle of cloth water impeller lower part and these pointed nozzle opennings Direction is consistent, it is made to coincide as far as possible each other.Meanwhile the bore inner diameter of water distribution impeller center also should be more bigger than the outer diameter of center pillar, that This forms certain gap, so that it smoothly moves up and down and rotate.

The utility model can be such that spray head is sprayed due to being provided with one in spray head upper end around the cloth water impeller that center pillar rotates The range and angle of current scour out are that circumferentially shape is continually changing, so will not there are pulping dead angles around center pillar. Since this cloth water impeller can constantly rise along center pillar, make this spray head to wash away range more extensive, than currently used The constant spray head in direction is washed away, spray field is expanded, water spray dead angle is eliminated, improves work efficiency.It is this to be set in spray head front end Not only rotatable but also liftable water distribution blade wheel structure is set, the mortar precipitated around spray head is also made to be more easier to be pulped, it is relatively existing There is method of disposal of the sand warehouse by heap buried when that can save a large amount of manpower and material resources.

When stopping water spray, the motive force for making cloth water impeller move upwards and rotate disappears, due under gravity nature Drop, all nozzle automatic pluggings that spray head front end ring can be arranged around center pillar, it is ensured that the mortar precipitated again around it cannot Into inside spray head, the purpose for preventing spray head blocked is realized, solve the problems, such as that big specification spray head is easy to be blocked, be spray head Enlargement provides possibility.
