Abstract
The utility model relates to a polyvinyl chloride sleeve sealer for polyvinyl chloride sleeve sealing in-situ uranium mining production. The sealer consists of a tray, a central pipe, a compression system and a sealing system; a compression device and a sealing device are connected by the central pipe; the tray is arranged on the upper end of the central pipe; a compression nut is arranged outside the central pipe by thread, and a compression washer and a pressure ring are subsequently arranged below; the lower end of the pressure ring contacts with a lower mobile compression disk; a sealing rubber ring set and a central ring are alternatively arranged between an upper mobile compression disk and the lower mobile compression disk; and the lower mobile compression disk is connected with the bottom of the central pipe by thread. The sealer effectively solves the problems of the sealing and the pressure bearing of the reagent-free in-situ uranium mining liquid filling well and liquid extracting well, and can be widely applied to the in-situ uranium mining production operation.
Description
Technical field:
The utility model relates to and is used for a kind of PVC sleeve sealer that ground-dipping uranium extraction is produced the middle sleeve sealing.
Background technology:
At present, aspect ground dipping uranium extracting process, that adopts both at home and abroad usually has three kinds of methods, be the notes acid system, annotate alkaline process and do not have the reagent method that with respect to annotating acid system and annotating alkaline process, no reagent method has the mining area and pollutes little respectively, the technology low cost and other advantages, meet ground-dipping uranium extraction technical development needs, but aspect no reagent method ground-dipping uranium extraction, also do not have the PVC sleeve sealer of moulding can solve uranium well PVC sleeve fluid injection well and sealing of drawing liquid well and pressure-bearing problem at present.
The utility model content:
The utility model purpose be to provide a kind of can excellent sealing technology well head in the non-reagent ground dipping uranium extracting operation, can bear a kind of PVC sleeve sealer of steam injection pressure again.
The utility model purpose is to realize like this.This kind sealer is made up of pallet, central tube, pressing system, sealing system, and its structure assembled relation is as follows, and pressing system is made of clamp nut, packing washer and pressure ring; Sealing device is by last mobile platen, sealing rubber ring group, center ring and move down the dynamic pressure dish and constitute, wherein, pallet is installed on the central tube upper end, central tube and clamp nut screw thread, the below is equipped with packing washer and pressure ring successively, the pressure ring lower end contacts with moving down the dynamic pressure dish, and sealing rubber ring group and center ring alternately are installed on mobile platen and move down between the dynamic pressure dish, moves down dynamic pressure dish and central tube and is welded to connect.During work, whole device is installed in fluid injection or the drawing liquid uranium well PVC sleeve, make the downward crush seal device of pressing system by rotatably compressing nut, rubber ring group expanded radially under the extruding of pressurizing unit in the sealing device, can be firm lean on oil well PVC sleeve wall, rubber ring group and internal surface of casing frictionally reach the purpose of sealing well head, can bear the steam injection pressure of the required 20-30 of a non-reagent ground dipping uranium extracting technology standard atmospheric pressure fully.
The utility model is reasonable in design, and reliable operation utilizes it can effectively solve the sealing and the pressure-bearing problem of non-reagent ground dipping uranium extracting fluid injection well and drawing liquid well.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model by pallet 1, central tube 2, clamp nut 3, compress liner 4, pressure ring 5, go up mobile platen 6, adapter ring 7, rubber ring group 8 and move down dynamic pressure dish 9 and form.Wherein: rubber ring group 8 is made for the pressure-resistant rubber material, constitute by 11-14 rubber ring, center ring and rubber ring group are formed a sealing unit, size and uranium well pressure-bearing situation according to fluid injection well and drawing liquid well PVC sleeve caliber, go up mobile platen 6 and move down 4-6 rubber ring group is housed between the dynamic pressure dish 9, center ring 7 and other parts are that corrosion-resistant oxidation resistant steel material is made.
