Semi-permanent mechanical throwing and fishing soluble shaft plugging bridge plug and method

The invention discloses a semi-permanent mechanical throwing and fishing soluble shaft plugging bridge plug and method, and belongs to the technical field of bridge plugs, the bridge plug comprises a throwing joint, a central pipe, a fishing joint, a guide cone, a slip and a setting mechanism, the central pipe and the guide cone are provided with limiting pieces used for being matched with axial displacement of the central pipe, the limiting pieces are dissoluble, and the fishing joint is connected with the slip. Through limiting cooperation, setting and unsetting of the setting mechanism are achieved; during setting, the slip fixes the bridge plug on the inner wall of the casing pipe through inertia, the central pipe is lifted upwards to drive the piston to extrude hydraulic oil in the rubber sleeve lower connector into the sealing rubber sleeve, so that the sealing rubber sleeve is expanded, setting is completed, and at the moment, the central pipe is meshed and fixed with the limiting piece; during unsealing, the limiting piece is dissolved, the central pipe can axially move, the sealing rubber sleeve automatically shrinks, and the bridge plug is recycled by grabbing the fishing connector; the device is simple in structure and principle, convenient to recycle, capable of saving use cost, high in plugging pressure and capable of providing help for oil and gas development and construction of oil fields.

A floating garbage salvaging device for sewage treatment

The present invention relates to the technical field of devices for separating oily floating objects, and specifically discloses a floating garbage salvaging device for sewage treatment, including a separation tank and a waste discharge pipe, wherein the waste discharge pipe discharges the oily floating objects gathered in the separation tank, and the waste discharge pipe is located at one end of the inner side of the separation tank and is connected to two salvage devices for gathering the oily floating objects, and the two salvage devices both include a vertical middle frame and a buoy that slides up and down along the middle frame. The present invention uses the design of the buoy so that the buoy moves up and down to generate waves in the sewage, and the sewage and the oily floating objects in the upper layer of the separation tank are gathered together in the buoy during the sewage fluctuations. When the buoy moves up and down to salvage the mixture of sewage and oily floating objects, it drives the oil separator to reciprocately stretch, expand and squeeze and contract. The buoy moves downward to further absorb and enrich the oily floating objects in the salvaged mixture, and the buoy moves upward to concentrate the enriched oily floating objects in the oil collecting barrel for centralized discharge.
