Abstract

The invention relates to the technical field of biomass fuel power generation boiler auxiliary equipment, in particular to a spiral ash discharging machine capable of effectively improving the ash discharging efficiency and the ash discharging effect. The spiral ash discharging machine comprises a base. The base is provided with an ash discharging machine body. The ash discharging machine comprises an outer barrel. A rotating shaft with spiral blades is arranged in the outer barrel and connected with a drive motor. The spiral ash discharging machine is characterized in that a feeding port is formed in the upper portion of the left end of an outer barrel body, and a discharging port is formed in the lower portion of the right end of the outer barrel body; the position, corresponding to the discharging port, of the rotating shaft is not provided with spiral blades so that a polish rod section can be formed; the part, located on the right side of the polish rod section, of the rotating shaft is provided with the forward spiral blades, and the part, located on the left side of the polish rod section, of the rotating shaft is at least provided with the two sets of reverse spiral blades; a water cooling pipeline is arranged in the rotating shaft, one end of the rotating shaft is provided with a water inlet pipe communicating with the water cooling pipeline, and the other end of the rotating shaft is provided with a water outlet pipe communicating with the water cooling pipeline; and a dirt outlet is further formed in the lower end of the outer barrel, the position of the dirt outlet is provided with a dirt discharging pipeline, and the dirt discharging pipeline is provided with a manual ash slag valve.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for biomass fuel power generation boilers, in particular to a screw ash discharger. Background technique [0002] The fuel used in biomass fuel power plants is waste from agricultural and forestry production such as straw, wheat straw, corn stalks, branches and bark, etc. These fuel ash contains a certain amount of trace elements such as potassium, which can be used as fertilizer or fertilizer. field. Biomass fuel usually contains a certain amount of alkali metal, which is prone to slagging after burning in the boiler. The industry usually uses a water-cooled screw ash machine to crush the slag discharged from the boiler, and then cool it to below 80°C for transport to the field. If the current existing screw ash discharger is used, the discharge port is prone to blockage, which affects the ash discharge efficiency and ash discharge effect. Contents of the invention [0003] In ord...
