Biomass molding machine with annular tooth-shaped mold

Abstract

The invention discloses a biomass molding machine with an annular tooth-shaped mold. When a biomass raw material enters a molding cavity, a tooth-shaped pressure roller and the annular tooth-shaped mold synchronously and relatively rotate, so that the raw material entering the molding cavity is fed into a molding mold hole under the mutual clamping action of the tooth-shaped pressure roller and the annular tooth-shaped mold instead of being extruded freely into the molding mold hole; a tooth-shaped pressure roller point is used for further pushing the raw material into the molding mold hole; the discharging speed of the raw material entering a molding mold under the forced pushing action of the pressure roller tooth point is not decreased, and hole blocking and machine halt are avoided; and the idle rotating time of the raw material which rotates along with the tooth-shaped pressure roller is reduced. The raw materials are pressed into the molding mold hole at any time, so that the characteristics of various raw materials and the sensitivity of the molding machine to the raw materials are lowered relatively, reactive loss is reduced, the abrasive degree is lowered, the suitability of the molding machine with the annular tooth-shaped mold for various raw materials is enhanced, the overall performance of the molding machine is enhanced greatly, and the technical defects of the conventional molding machine are overcome remarkably.

Description

Technical field: [0001] The invention belongs to solidification and compacting molding equipment of biomass solid fuel. The invention mainly relates to a molding process technology of a solidification molding equipment for biomass fuels such as crop straws and solid wastes. technical background: [0002] After more than 20 years, my country's biomass fuel molding technology has made great progress. So far, there are hundreds of domestic biomass fuel molding machine companies, and the types of biomass fuel curing molding machines have also been established. There are ring die machines, flat die machines, rotary extruders, double-roller presses, and the output of molding fuels has exceeded one million tons. However, some key technical problems of biomass molding machines have not been found in practice. It has been well solved, such as: a series of problems such as low production capacity of the molding machine, high specific energy consumption, high failure rate, and short ser...

[0002] After more than 20 years, my country's biomass fuel molding technology has made great progress. So far, there are hundreds of domestic biomass fuel molding machine companies, and the types of biomass fuel curing molding machines have also been established. There are ring die machines, flat die machines, rotary extruders, double-roller presses, and the output of molding fuels has exceeded one million tons. However, some key technical problems of biomass molding machines have not been found in practice. It has been well solved, such as: a series of problems such as low production capacity of the molding machine, high specific energy consumption, high failure rate, and short service life of key components have become restrictions on the promotion of biomass molding fuels and supporting biomass stoves and biomass boilers. application bottleneck
