Organic solid waste spiral charge pump

Abstract

The invention discloses an organic solid waste spiral charge pump. A first-stage spiral charge pump is provided with a hopper, wherein the hopper is provided with a first spiral rod driven by a first motor, the upper section of the first spiral rod is provided with a flexible stirring fin, and the lower section of the first spiral rod is provided with spiral blades; a second-stage spiral feeder is sequentially provided with three sections of communicated working areas, a first working area is a material propelling area, a cantilever type second spiral rod driven by a second motor is arranged in a cylinder body of the first working area, the second spiral rod is provided with spiral rod blades, the whole second spiral rod is arranged in the first working area, a second working area is a sealing area, the diameter of a cylinder body of the second working area is as same as the diameter of the cylinder body of the first working area, a third working area is a diffusion area, and the diameter of a cylinder body of the third working area is larger than that of the cylinder body of the second working area. The organic solid waste spiral charge pump disclosed by the invention has a reasonable structure, is safe and controllable and does not pollute environment in a charging process.

Description

technical field [0001] The invention relates to a screw feeding pump for organic solid waste. Background technique [0002] At present, for the pyrolysis disposal and utilization of organic solid waste, positive pressure and high temperature processes are generally used, such as waste plastics, organic solid waste of domestic garbage, and biomass raw materials for pyrolysis. Due to the low bulk density of these materials, they are generally less than 200 kg / m3, using a conventional screw conveyor to feed, the filling factor of the material is less than 0.5, oil and gas leakage occurs in the positive pressure operation of the reactor; the bulk density of the material is small, and the feeding is often interrupted due to material bridging and arching, which seriously affects the barrier Pyrolysis process implementation of organic solid waste. Contents of the invention [0003] The object of the present invention is to provide a screw feeding pump for organic solid waste wit...
