Abstract
The utility model relates to oil extraction equipment, in particular to an oil extraction filter sand anti-clamping device. The technical scheme of the device is as follows: a lower tube body is connected with an upper tube body through threads; an elastic contraction mechanism is fixed at the bottom of the lower tube body; a rotating mechanism is connected to the upper tube body; the top of a sand-proof outer tube is connected with the rotating mechanism, and the bottom of the sand-proof outer tube is connected with the elastic contraction mechanism; the elastic contraction mechanism comprises a base and an expansion ring; and the upper part of the base is connected with the sand-proof outer tube through the expansion ring. The oil extraction filter sand anti-clamping device has the benefits as follows: the sand-proof outer tube can move up and down by the aid of the elastic contraction mechanism, and sand clamping caused between the sand-proof outer tube and the upper tube body as well as the lower tube body is avoided; rotating of the sand-proof outer tube is realized by the aid of the rotating mechanism, sand produced by separation and filtration is effectively cleared, and the oil extraction efficiency is improved; and the sand-proof outer tube can move up and down by the aid of the elastic contraction mechanism, resistance is reduced, blocking is not easy to occur, and mounting and dismounting are convenient.
Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of oil recovery filter sand antiseize device.
Background technology
At present, the oil recovery filter sieve tube using on oil production equipment is divided into common round and degree of depth type, common round complex structure, and intensity is low, and filtering traffic area is little, and the silt blocking filtration beds that easily becomes silted up reduces filter effect short application life; Degree of depth type filter sieve tube filtering layer is thick, and resistance is large, easily stops up, and life cycle is short, installs simultaneously, dismantles inconvenience.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil recovery filter sand antiseize device is provided.
Its technical scheme is: comprise upper shell, lower shell, elastic shrinkage mechanism, rotating mechanism, sand control outer tube, lower shell is threaded connection upper shell, the bottom fixing elastic shrinkage mechanism of described lower shell, connection traversing mechanism on described upper shell, the top connection traversing mechanism of described sand control outer tube, the bottom of described sand control outer tube connects elastic shrinkage mechanism, described elastic shrinkage mechanism comprises base and expansion ring, base top connects sand control outer tube by expansion ring, described base is provided with protruding gear, the bottom of expansion ring is fixed by the protruding gear on base, the top of expansion ring connects sand control outer tube by drag hook.
Above-mentioned sand control outer tube comprises inner layer sleeve, outer layer sleeve, between inner layer sleeve and outer layer sleeve, is provided with separation layer, and described separation layer is loop configuration, and described separation layer is provided with oil seepage hole.
The bottom of above-mentioned sand control outer tube is inverted cone-shaped structure, and inverted cone-shaped structure is convenient to the filtering-depositing of grit, avoids causing the obstruction to elastic shrinkage mechanism.
The beneficial effects of the utility model are: by moving up and down of elastic shrinkage winding machine sand control outer tube, avoid causing between sand control outer tube and upper shell and lower shell sand card, rotating mechanism is realized the rotation of sand control outer tube, the grit that effectively cleaning separating and filtering produces, improve oil recovery efficiency, by moving up and down of elastic shrinkage winding machine sand control outer tube, reduce resistance, be not easy to stop up, installation, convenient disassembly, the bottom of sand control outer tube is the filtering-depositing that inverted cone-shaped structure is convenient to grit, avoids causing the obstruction to elastic shrinkage mechanism.
