The utility model relates to centrifuge technical field, concretely relates to a shock absorption and noise reduction type horizontal spiral unloading filter centrifuge, and the mounting seat is equipped on the frame, the drive motor is arranged on the mounting seat, the drive motor outside is equipped with the sound shield main part, the bottom embedding setting of sound shield main part is equipped with permanent magnet, the mounting seat upper end is equipped with the electromagnetic coil that cooperates with permanent magnet, the frame is equipped with hall sensor and PID controller, the mounting seat outside surrounds and is provided with rectangular frame body, the sound shield main part and rectangular frame body side wall slide and fit, eliminate the direct rigid mechanical contact of sound shield and mounting seat through the suspension state, reduce the transmission of drive motor vibration through the sound shield main part to the frame, and further reduce the overall equipment vibration, and the sound shield main part wraps drive motor and blocks noise emission, guarantees good operating environment and personnel health.

The invention relates to the technical field of oil exploration, in particular to a preparation method of an ultra-high-temperature suspension stabilizer, a product and application of the ultra-high-temperature suspension stabilizer in oil well cement. The preparation method comprises the following steps: dissolving a 2-acrylamide-2-methylpropanesulfonic acid monomer, a temperature-sensitive monomer and an N-vinyl pyrrolidone monomer in water to obtain a monomer solution; adding an initiator into the monomer solution, and heating to 30-60 DEG C to obtain a mixed solution; adding a reducing agent into the mixed solution for reaction to obtain a polymer solution; and freeze-drying the polymer solution to obtain the ultrahigh-temperature suspension stabilizer. When the suspension stabilizer obtained by the preparation method is added into an oil well cement paste system, the suspension stability of the cement paste in an ultrahigh-temperature environment can be maintained, and the initial consistency of the cement paste is not too large. The raw materials are convenient and easy to obtain, the preparation method is simple, the application requirements are met, the suspension stability of an ultrahigh-temperature cement slurry system can be effectively improved, and the safety of well cementation operation is guaranteed.

This utility model relates to the field of disposable hygiene products, and more particularly to a side-hanging, pull-out hygiene product. It primarily solves the problem of poor replaceability of existing wall-mounted pull-out products. The product includes a pull-out hygiene product body, comprising stacked products and a packaging bag covering the product's perimeter. The packaging bag has six sides: a top side, a bottom side, a front side, a rear side, a left side, and a right side. The bottom side of the packaging bag has a pull-out opening formed by a first tear line. The rear side of the packaging bag has at least one first hanging opening formed by a second tear line. The first hanging openings are distributed in a horizontal direction, and the distance between the first hanging opening and the upper edge of the rear side is 2cm to 8cm.
