The invention relates to the field of rescuing fire fighting trucks, in particular to a bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck. The bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck comprises a truck frame and road traveling bridges connected to the truck frame, and further comprises rail traveling systems, each rail traveling system comprises an upper rotation base, a lower rotation base and a swinging arm, the upper rotation bases are fixedly connected with the truck frame, the lower rotation bases are connected with the upper rotation bases in a rotatable mode, and one ends of the swinging arms are hinged to lower landing legs of the lower rotation bases. According to the bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck, wheel pairs have the rotation characteristic, compared with the conditions that in the prior art wheel pairs are pressed through a rail to carry out steering, and reverse braking is achieved through a driving system, a braking mode of the bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck is not limited by the 40-Km / h truck speed any more, the speed is one time higher than that of a conventional road-rail truck, and the emergent and rapid requirements during fire rescuing can be met.

The invention discloses a method for recycling of soybean whey wastewater by a membrane separation technology. The method includes: sterilization pretreatment; flocculation and centrifugal separation for impurity removal; whey protein recovery by ultrafiltration membrane continuous separation; whey protein powder recovery; oligosaccharide syrup recovery by nanofiltration membrane continuous concentration; oligosaccharide recovery; and dialysis water recovery by reverse osmosis membrane continuous concentration. The method provided in the invention can avoid whey wastewater rancidity and ultrafiltration membrane pollution and plugging, and improves the product quality. Employment of the continuous separation concentration mode reduces stay of intercepted objects or protein, impurity concentrated liquors in a membrane assembly to the utmost, and back-and-forth circulation between a membrane liquid inlet tank and a membrane system no longer exists. Meanwhile, the membrane surface flow speed is controlled, so that the problems of membrane pollution and low separation efficiency are solved. An osmosis filtration membrane washing process is adopted, and water is added automatically for filter wash, so that the membrane pollution and plugging problems are solved, and the product quality is improved. The selection of high temperature resistant hydrophilic membrane materials guarantee a high water flux and help to reduce membrane pollution.

The invention discloses a permanent-magnet cylindrical cage type high-gradient magnetic separator with high processing capacity. A separating cylinder (2) is a cylindrical cage which is a rotary body and is filled with magnetic matrices (4); two ends of the cylindrical cage are supported on a hollow support shaft (3) through bearings; a magnetic system is a permanent-magnet lattice uniform magnetic field system formed by an upper magnetic system and a lower magnetic system, the upper magnetic system is arranged in the cavity of the cylindrical cage and suspended on the hollow support shaft (3), the lower magnetic system is installed outside the cylindrical cage, the hollow support shaft (3) is a non-rotary body, one end of the hollow support shaft (3) is used as an axes feeding port (12),the middle of the hollow support shaft (3) is provided with a baffle plate, and one side of the baffle plate of the hollow support shaft is provided with a separating and feeding port close to the feeding port (12), the other side of the baffle plate of the hollow support shaft is provided with a concentrate feeding port (14), and the other end of the hollow support shaft (3) is used as a concentrate discharging port (13). The permanent-magnet cylindrical cage type high-gradient magnetic separator has the advantages of easiness for maximization, convenience for design and production, low energy consumption, reasonable magnetic distribution, uniform background magnetic field working region as well as high processing capacity and stable separation indexes under limited tonnage and volume.

The invention discloses a combined aluminum alloy double-wall drill pipe unit composed of an inner pipe, an outer pipe, an upper connector of the outer pipe, a lower connector of the outer pipe, an upper connector of the inner pipe, a lower connector of the inner pipe and seal rings. Two ends of the outer pipe are connected with the upper connector of the upper pipe and the lower connector of the outer pipe through clamping slots, respectively. The seal rings are arranged on matched cylindrical surfaces between the outer pipe and the upper connector of the outer pipe as well as between the outer pipe and the lower connector of the outer pipe. The inner pipe is arranged in the outer pipe. Two ends of the inner pipe are connected with the upper connector and the lower connector of the inner pipe through threads, respectively. As the combined aluminum alloy double-wall drill pipe units coupled, two adjacent outer pipes are in threaded connection through the upper connectors and the lower connectors of the outer pipes, and the inner pipes are in inserting connection through the upper connectors and the inner connectors of the inner pipes. The outer pipe made of aluminum alloy is 1 / 3 of steel in density, leading to light weight and carrying convenience. The combined aluminum alloy double-wall drill pipe unit is light, convenient to carry, simple in structure, easy to detach, reasonable in load distribution, accurate in the centering position between the inner pipe and the outer pipe, good in stress working condition and the like.
