The invention discloses a composite integrated membrane filter element. The composite integrated membrane filter element comprises a carbon ceramic tube membrane, ion exchange active carbon fiber membranes, brominated resin and a membrane core tube, wherein the membrane core tube is provided with a vertical tube part; the ion exchange active carbon fiber membrane, the brominated resin and the ion exchange active carbon fiber membrane are arranged in the tube cavity of the vertical tube part from the opening end to the other end in sequence; the carbon ceramic tube membrane covers the peripheral side of the vertical tube part; water penetrates from the carbon ceramic tube membrane and enters the inner cavity from the opening end of the vertical tube part of the membrane core tube, and flows out from a water outlet of the membrane core tube after being filtered and softened by virtue of the ion exchange active carbon fiber membrane, the brominated resin and the ion exchange active carbon fiber membrane in sequence, and remaining mineral substances in water are about 20%. The composite integrated membrane filter element disclosed by the invention is suitable for filtering northern drinking water with great hardness without losing mineral nutrients in water, and can be used for obtaining drinking water which is free of thermonatrite or water scales in the sensory, and relatively good in mouthfeel.

The invention relates to a high-vacuum multi-layer heat-insulating deep-cooling double-shell spherical storage tank, which comprises an outer spherical tank and an inner spherical tank, wherein the inner spherical tank is placed in the outer spherical tank; the inner spherical tank is supported in the outer spherical tank through an upper fixed supporting member which is arranged on the upper part of the inner spherical tank and a lower fixed supporting member which is arranged on the lower part of the inner spherical tank; a laminated inner supporting member is arranged between the inner spherical tank and the outer spherical tank; a heat-insulating material is coated on an outer surface of the inner spherical tank; a reinforcing plate is arranged on the outer surface of the outer spherical tank; the reinforcing plate is welded with an upper supporting column through an equator tangential structure; the upper supporting column is fixedly connected with a lower supporting column through the heat-insulating material; and a pulling rod is connected between the upper supporting column and the lower supporting column. By adoption of a mixed spherical shell structure, the supporting columns are welded on the reinforcing plate on the outer surface of the outer spherical tank through the equator tangential structure, so the carrying capacity of the supporting columns is ensured; and a high-vacuum multi-layer heat-insulating cold-insulating structure is adopted between the inner spherical tank and the outer spherical tank, and the inner supporting member has a laminated supportingstructure, so the problem of telescoping of the supporting member caused by temperature change is solved, and the light weight of the storage tank and volume maximization are realized.

The invention discloses a boiler, which relates to the technical field of sewage treatment. The boiler comprises: a first gallbladder extending along an axis; a scraper arranged in the first gallbladder, the scraper extending along a cylindrical helix , the scraper can rotate around the axis, and the outside of the scraper can scrape off the scale or dirt on the inner wall of the first bladder; a transmission mechanism, the transmission mechanism is connected with the scraper to The blade can be rotated. The application can treat sewage, and can automatically remove scale and sundries produced by sewage in the cavity.

The invention provides an anti-falling device and a transport cart with the same. The anti-falling device is used for preventing a hydraulic cylinder on the transport cart from falling off. The anti-falling device comprises an anti-falling plate, the anti-falling plate is movably arranged relative to the hydraulic cylinder, and the anti-falling plate has an avoiding position and a stopping position, wherein when the anti-falling plate is located at the stop position, the anti-falling plate at least partially moves to the bottom of the hydraulic cylinder so as to stop the hydraulic cylinder from extending downwards or falling, and when the anti-falling plate is located at the receding position, the anti-falling plate moves away from the hydraulic cylinder. The anti-falling device solves theproblem that in the prior art, a hydraulic cylinder of a piggyback transport vehicle is prone to falling in the running process.
