The application relates to a rectangular furnace bottom structure in the technical field of pyrometallurgical furnace equipment, and in particular to a rectangular furnace bottom structure. The rectangular furnace bottom structure comprises, from bottom to top, a heat preservation layer, a ramming layer, a safety layer and a working layer in sequence. The lower half of the heat preservation layer is filled horizontally, the upper half of the heat preservation layer is a structure symmetrically retreating to both sides, forming an arc-shaped surface, an arc-shaped ramming layer with a high middle and a low both ends is filled above the heat preservation layer, the safety layer and the working layer are sequentially built on the ramming layer, the upper surface of the working layer is arc-shaped with a high middle and a low both ends, a molten metal copper jacket is arranged on the adjacent furnace wall of the safety layer and the working layer, and a molten metal outlet is arranged in the molten metal copper jacket. The straight surface of the furnace bottom structure is changed into an arc surface, the structural strength and stability are high, the heat preservation layer and the working layer are closely contacted, the molten body leakage is prevented, the brick body expansion can be absorbed, the construction is convenient, the cost is low, and the rectangular furnace bottom structure is suitable for furnaces of different sizes.

This invention provides a flat-wire motor and a vehicle having the same, comprising: a stator core with multiple stator slots evenly distributed circumferentially; a stator winding having three-phase windings disposed within the stator slots, each phase winding having two parallel branch windings, each branch winding being composed of multiple coils connected in series, the multiple coils connected in series forming a forward cross-layer winding, a reverse cross-layer winding, and a same-layer winding, the same-layer winding being connected in series between the forward and reverse cross-layer windings, the forward and reverse cross-layer windings being arranged in parallel; wherein, the phase leads of the stator winding are continuously distributed within the same layer of stator slots. The same-layer winding is located at the turning point of the winding, changing the cross-winding direction and position of the winding, the cross-winding angle of the forward and reverse cross-layer windings remains consistent, the output and input ends of each branch winding are located in the same layer, and each branch winding can be wound synchronously, realizing the switching between continuous wave winding technology and pin-insertion winding technology.

The arc extinguishing chamber and the switching device aim at improving the overall arc extinguishing efficiency.

The utility model relates to the technical field of ventilation, and provides a green low-carbon air pipe and outer wall air port mounting structure which comprises an outer wall provided with an air port, shutters mounted in the air port and an air pipe arranged indoors and communicated with the air port. The shutter is installed at the position, close to the outdoor space, of the air opening, a hollow fixing frame is installed at the position, close to the indoor space, of the air opening, the fixing frame is provided with a clamping groove, and the space between the connecting position of the shutter and the air opening and the fixing frame is filled with heat insulation materials. The end, close to the air opening, of the air pipe is provided with a skirt edge which is folded outwards, and the skirt edge of the air pipe is connected into the clamping groove in a clamped mode. The hollow fixing frame is arranged in the tuyere, the skirt edge of the air pipe is clamped in the clamping groove of the fixing frame, and the air pipe is movably connected with the tuyere, so that the noise of the air pipe can be reduced, the sealing performance of the joint of the air pipe and the tuyere is ensured, the heat bridge breaking effect of the air pipe and the tuyere can be improved, and in addition, the air pipe is also convenient to disassemble and assemble.

This utility model provides a feeding device for a rubber internal mixer, relating to the field of feeding devices. It includes a mixing tank, with a rotating plate movably connected to the top of the mixing tank via a bearing. A feeding hopper is fixedly connected to the top of the rotating plate, and a discharge hopper is fixedly connected to the bottom of the mixing tank. A scraping mechanism is provided inside the mixing tank. This utility model, by setting up a mixing tank, serves as a transition for adding raw materials. The feeding hopper facilitates the addition of components into the mixing tank. The discharge hopper is inserted into the feed port of the internal mixer to add the raw materials from the mixing tank into the internal mixer, achieving the feeding purpose. The scraping mechanism agitates the raw materials added to the internal mixer, preventing them from sticking to the inner wall of the mixing tank and providing a certain degree of agitation. This agitation prevents the raw materials from sticking to the walls, thereby improving the overall service life of the equipment.
