The invention discloses a permanent magnet synchronous motor for a hoisting mechanism of a direct-drive crane; the permanent magnet synchronous motor comprises a permanent magnet synchronous motor shell, a stator winding, a stator iron core, a permanent magnet, a rotor, a winding drum revolving shaft and a winding drum; and the permanent magnet synchronous motor has more than 20 poles. In the invention, by increasing the number of the poles of the permanent magnet motor, a variable-frequency power source is adopted to realize low-speed operation of the motor, high torque is output, the motor directly drives the load to work, a speed reducer is canceled, the structure is simple and practical, and the working efficiency of the system is improved; a rotor structure adopted by the invention can effectively solve the problem of difficult assembly of the permanent magnet motor; rotor magnetic poles and magnetic separation steel rings commonly protect the permanent magnet from being damaged when in assembly; reluctance torque is reduced to be zero in the installation process, the installation difficulty is reduced, and requirements and dependence to installation tools (special mounting equipment) is reduced, and the quality of the rotor and the complexity of the rotor structure are greatly reduced.

The invention relates to the field of ball mills with drying bins, in particular to an interchangeable drying bin-separating device for an air-swept coal mill. The interchangeable drying bin-separating device comprises a combined supporting frame, a conical discharging body, a plurality of lifting plates and bin-separating grid plates; the combined supporting frame comprises an annular fixing frame with the U-shaped section, the periphery of the fixing frame is fixed to a mill cylinder, and a supporting plate with a central hole and a baffle are connected to the two sides of the fixing frame respectively through bolts; the bin-separating grid plates are connected to the side, facing a grinding bin, of the fixing frame through bolts; the conical discharging body is arranged in the central hole of the combined supporting frame and is connected and fixed to the supporting plate, and a plurality of butt plates used for fixing the lifting plates are arranged in the peripheral direction of the conical discharging body; each lifting plate is composed of one arc-shaped curved plate and two side plates, is embedded between the baffle and the supporting plate and is connected to the supporting plate through one side plate and a bolt. According to the interchangeable drying bin-separating device, the interchangeability of the bin-separating device can be improved, the material accumulation problem of a drying bin can be solved, the mill efficiency can be improved, assembly is easy, and the potential safety hazard of bolt breakage is avoided.

The invention relates to the technical field of communication, and discloses an optical fiber device feeding discharging module. The optical fiber device feeding discharging module comprises a feedingdevice and a discharging device. The feeding device comprises a lifting material cabin assembly, fixture assemblies and a fixture taking assembly. The lifting material cabin assembly is used for layering and stacking the fixture assemblies, and controlling lifting of layering and stacking the fixture assemblies in the lifting material cabin assembly. The fixture taking assembly is used for takingthe layered and stacked fixture assemblies on the lifting material cabin assembly one by one. The optical fiber device feeding discharging module has the advantages that through the lifting materialcabin assembly, the displacement volume is improved; through the fixture taking assembly, single fixture can be taken; conveying is convenient; and conveying accuracy after positioning is improved.

The invention provides a packaging liner for household appliance and a household appliance component, wherein one end of the packaging liner is provided with a first mounting groove for mounting the home appliance and the other end of the packaging liner has a bottom surface, and the packaging liner has a side surface which is connected between one end of the packaging liner and the other end of the packaging liner in a transition mode. The side surface includes an inclined surface area which is inclined in a direction from one end of the packaging liner to the other end of the packaging linerand is provided with a boss structure. The packaging liner for the household appliance can take both the assembly efficiency and the protection reliability of a product into consideration, so that the overall quality of the product is effectively improved and the promotion of the product in the field is facilitated.

The invention discloses a steam generator inclined tube bundle heat exchange experimental device and method. The experimental device comprises an inclined tube bundle, a rectangular sleeve, an inlet diverging section, an outlet converging section, a rectifier, an inlet connector and an outlet connector, wherein the inlet diverging section and the inlet connector are welded at the lower part of therectangular sleeve in turn, the outlet converging section and the outlet connector are sequentially welded on the upper part of the rectangular sleeve, the inclined tube bundle is inserted into the rectangular sleeve obliquely downwards at an angle of 45 degrees from the outside through a reserved through hole, the rectifier is installed at the lower part of the rectangular sleeve, and the experimental device is connected to a whole test pipeline system through the inlet connector and the outlet connector. The experimental device has a simple overall structure, is easy to process, is low in cost, and provides a simulator for studying the flowing and heat transfer characteristics of inclined tube bundles of steam generators. The invention also provides the experimental method of the experimental device. The method can be used to carry out experiments of single-phase water and steam-water two-phase fluid, and test and verify the heat transfer characteristics of the inclined tube bundlesof the steam generators by changing inlet parameters of a working medium.

The invention provides a novel wind ring assembly of an automobile engine. The novel wind ring assembly comprises a wind ring, and an open type pressing rivet structure is formed in the axle journal of the wind ring. The open type pressing rivet structure is stressed after a rubber ring is arranged into the open type pressing rivet structure, and an opening of the open type pressing rivet structure is contracted to clamp the rubber ring and the wind ring assembly is formed. The rubber ring is extended in the axial direction to form a horn mouth. A thickness sudden-change structure is arranged on the connecting section between an extended part of the rubber ring in the axial direction and a wind cover, and the rubber ring can be freely turned and folded. The opening angle alpha of the horn mouth is 10-50 degree. According to the novel wind ring assembly, the open type pressing rivet structure is formed in the axle journal of the wind ring, the open type pressing rivet structure is pressed after the rubber ring is arranged into the open type pressing rivet structure, and the opening of the open type pressing rivet structure is contracted to clamp the rubber ring and the wind ring assembly is formed, the rubber ring is extended in the axial direction to form the horn mouth, the thickness sudden-change structure is arranged on the connecting piece between the extended part of the rubber ring in the axial direction and the wind cover, and the rubber ring can be in the state of being freely turned and folded, so that the axial dimension, namely the total length, of the wind ring assembly is reduced.
