The utility model relates to the technical field of rotary cracking incinerators, in particular to a vertical rotary cracking incinerator with a fire grate, which comprises an incinerator body, a discharging pipeline is mounted in the center of the outer wall of the incinerator body and is communicated with the incinerator body, the rotary fire grate is mounted in the incinerator body, and the fire grate is communicated with the discharging pipeline. A plurality of contact rollers are mounted on the periphery of the rotary grate through a bracket; when a certain amount of waste is accumulated on the rotary fire grate, an electric telescopic rod is started to enable a first material blocking ring and a second material blocking ring to rotate mutually, so that a first discharging opening and a second discharging opening are aligned to each other, and at the moment, the waste can enter a discharging pipeline through the first discharging opening and a shifting rod; and under the stirring of the track stirring plate, the waste enters the material collecting box through the feeding pipeline, so that the collection of the accumulated waste which is not easy to crack on the rotary grate is realized, the bad influence of the waste accumulation on the gas flow in the furnace and the gap discharging of the grate is prevented, and the practicability of the device is improved.

The utility model discloses a wind-proof suit with a thickened inner container, which relates to the technical field of wind-proof suits and comprises a wind-proof suit outer sleeve and a down-filled inner sleeve, outer sleeves are arranged on the outer surfaces of the two sides of the wind-proof suit outer sleeve, a cap is detachably connected to the outer surface of the upper end of the wind-proof suit outer sleeve, a pocket is arranged on the outer surface of the front end of the wind-proof suit outer sleeve, and the down-filled inner sleeve is arranged in the pocket. A tightening edge is arranged on the outer surface of the lower end of the windcheater outer sleeve, a protective wrapping piece is arranged on the outer surface of the rear end of the outer sleeve, a lining sleeve is arranged in the middle of the outer sleeve, and a thickened cotton bale and a first hook-and-loop fastener are arranged on the inner surface of one end of the down-filled inner sleeve. According to the windproof garment with the thickened inner container, the thickened cotton bale can be in butt joint and pasted with the first hook-and-loop fastener through the second hook-and-loop fastener when used, the thickened cotton bale can be attached to the interior of the down-filled inner sleeve, the heat retention property of the down-filled inner sleeve can be improved, and the windproof garment with the thickened inner container can be rapidly disassembled and assembled according to needs and is convenient to use.

The utility model discloses a sintering device for a positive electrode material of a lithium ion battery, which belongs to a sintering device and completes a sintering process of precursor powder in an inert gas environment. Comprising a base, a feeding assembly located on the base, a heating wire used for increasing the temperature of the feeding assembly to the reaction temperature and a vibrator fixedly connected with the feeding assembly, and the two ends of the feeding assembly are the feeding end and the discharging end respectively; precursor powder enters the feeding assembly from the feeding end, is flatly laid on the feeding assembly under the vibration effect of the vibrator, moves towards the discharging end and falls out of the discharging end; the problems that static stacking type sintering is adopted in a high-temperature solid-phase method, due to material stacking, the sintering temperature is high, the sintering period is long, energy consumption is large, and due to material stacking, the sintering reaction is incomplete, half-cooked or the material performance is unstable are solved.

The application discloses a design method of a cooling tower air separation device, the cooling tower air separation device and the cooling tower, and relates to the technical field of cooling towers. The design method comprises the following steps: determining the configuration scale of a cooling tower body; determining the spacing between an air separation plate and a cooling tower shaft well, the air separation plate being arranged in an air inlet area inside the cooling tower body; determining the spacing according to the natural wind speed, the dominant wind direction and the configuration scale of the cooling tower body, and optimizing the spacing according to the packing stability under the natural wind; and determining the spacing between the air separation plates according to the wind load force distribution of the air separation plate, so as to arrange a support structure between the air separation plates, under the optimized spacing between the air separation plate and the cooling tower shaft well. The natural wind in the air inlet area is redistributed by arranging non-continuous air separation plates in the air inlet area, the air flow field state of the air inlet area is adjusted, the resistance of the natural wind passing through the air inlet area is increased, the draught is avoided, the flow field distribution of the packing area under the natural wind is more uniform, and the influence of the natural wind on the thermal performance of the cooling tower is reduced.
