Abstract
A valve used at bottom of underflow pool is featured as passing valve stem top end through valve base and using hand wheel to regulate it up and down through screw thread, setting valve stem to be hollow tubular structure and making its head of top end be pipe nozzle as well as connecting its bottom end to hollow and hammer-shaped valve head, opening a numbers of injection holes all round on side surface from valve head to bottom point and setting valve head right above valve base.
Description
Technical field
The present invention relates to a kind of emissions adjustment valve that is used for ore dressing ore pulp thickening pond, be specially a kind of bottom valve in density pond.
Background technique
At present, ore pulp that ore dressing produces generally will be delivered to thickening pond and carry out concentration, and ore pulp is discharged through bottom valve in density pond and reached the needed concentration of ore dressing.The bottom valve in density pond structure of prior art is made of valve rod, valve head and handwheel, the valve rod upper end is passed valve seat and is passed through the screw thread up-down adjustment by handwheel, the valve head of valve rod lower end is on the valve base of thickening pond floss hole, but because the ore discharge working procedure of thickening pond is a cycle discontinuity, and the liquid-solid ratio of ore pulp is about 30%, and settling velocity is fast.The long obstruction floss hole that is easy to harden of time one.Simultaneously the valve rod piece that can be hardened again " glue ", and causes the increase of operated by handwheel resistance.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of adjusting pulp concentration, does not stop up the bottom valve in density pond that the handling resistance is little.
Technical solution of the present invention is: a kind of bottom valve in density pond, constitute by valve rod, valve head and handwheel, and the valve rod upper end is passed valve seat and is passed through the screw thread up-down adjustment by handwheel, and valve head is over against the valve base top; Described valve rod is hollow tubular structure, and the top, upper end is processed into pipe and is chewed interface, the imitative capitate valve head of following termination hollow, and this valve head has several spray-holes around one section side of vertex (vertices).
Further, also be welded with one to two small-caliber seamless steel pipe in the described valve rod, the lower end of these small-caliber seamless steel pipes connects the valve rod tube wall spray-hole of respective amount on every side respectively.
When thickening pond needed ore discharge, the adjusting handle valve rod drove on the valve head and carries, and valve head leaves over against the valve base of the floss hole of thickening pond, and ore pulp falls into floss hole and discharges, otherwise valve head is closed the valve base of thickening pond floss hole.If when running into ore pulp caking and stopping up floss hole, when carrying on the control valve head, chew interface to pipe and feed high pressure water, current dash ore in sand form around penetrating at a high speed from the spray-hole of valve head, and the impulsive motion that will lump becomes fluid to discharge from floss hole, having dredged the caking obstruction.
Owing to adopted technique scheme, the present invention compares with prior art, and the valve head the present invention who is designed to imitate capitate and have spray-hole has the adjusting pulp concentration, has solved the difficult problem that thickening pond floss hole slurry sand plate knot stops up, and simple to operate reasonable, operate advantages such as resistance is little.The present invention simultaneously can also expand fields such as being applied to deposition tank, cesspool except that being used for the ore dressing thickening pond.
