The utility model relates to the high polymer material production technical field with gas as raw material, concretely is a kind of production polyketone with stirring mechanism and reaction kettle. Including main shaft and with the main shaft connection a group of upper stirring rod, at least upper hollow tube in main shaft, with the lower end of upper hollow tube corresponding place is provided with the hollow crossbeam that is communicated with upper hollow tube, at least part upper stirring rod is connected with hollow crossbeam, and upper stirring rod is provided with the vent line that is communicated with hollow crossbeam, vent line is provided with gas outlet hole;Upper hollow tube is in and is provided with the first air inlet pipe of the first check valve of lower end with first. The utility model passes through the upper and lower passage of main shaft in reaction kettle and makes the air inlet pipe and stirring assembly combination, and the gas to be reacted can be directly passed into the bottom of the liquid to be reacted, so that it is fully contacted, and then the cooperation of upper stirring rod and lower stirring rod, thereby the effect of gas-liquid mass transfer is improved, the reaction efficiency is improved, and the polyketone product is effectively prevented from walling and caking in kettle.

The utility model discloses an automatic batching machine for small materials, and relates to the technical field of batching machine production, the automatic batching machine comprises a batching assembly and an auxiliary assembly, the batching assembly comprises a supporting top plate and a material storage part, a weighing feeding cylinder is fixed on the inner wall of the supporting top plate, a stirring part is fixed on the top of the supporting top plate, and the auxiliary assembly is fixed on the supporting top plate. The storage part is arranged at the bottom of the supporting top plate, supporting legs are fixed to the bottom of the supporting top plate, the auxiliary assembly comprises a discharging part and an elastic cleaning part, and a flow guide part is arranged at the bottom of the discharging part and fixed to the inner wall of the storage part. According to the device disclosed by the utility model, through the matching of the batching assembly and the auxiliary assembly, various raw materials can be accurately weighed and automatically and uniformly mixed, meanwhile, in the mixing process, the inner wall of blanking equipment can be cleaned to avoid the situation that residual materials are hung on the wall, and corresponding required additives are automatically added in a targeted manner.
