Hydraulic forming machine set for moulding and solidifying biomass

Abstract

The invention relates to a hydraulic forming machine set for moulding and solidifying biomass, which comprises a hydraulic station, a feeder, a forming machine and a control cabinet, wherein the feeder comprises a hopper and a conveyer belt; the forming machine is formed by connecting a base, a support cylinder and a die pressing device sequentially; a main shaft is arranged in the support cylinder; the die pressing device comprises a die pressing plate, a connecting plate, a pinch roller shaft and two pinch rollers; the die pressing plate is sleeved at the top end of the support cylinder; a circle of circular discharging die holes are formed on the die pressing plate; the top end of the main shaft is connected with the connecting plate; the pinch roller shaft runs through the connecting plate horizontally; the pinch rollers are respectively sleeved at both ends of the pinch roller shaft; and a track formed by rotating the pinch rollers around the main shaft is positioned above the discharging die holes of the die pressing plate and is in clearance fit with the upper surface of the die pressing plate. The hydraulic mould forming machine set is driven by full hydraulic power, and the pinch rollers perform rotation while performing revolution, so that the biomass is formed by rolling compaction through the discharging die holes, and the hydraulic forming machine set has the advantages of simple integral structure, high hydraulic power, low energy consumption, long service life, good effect of rolling compaction, high density of formed blocks and good burning effect, and is suitable for forming various biomass straws.

Description

technical field [0001] The invention relates to a biomass molding unit, in particular to a molding unit for hydraulic power, molding and solidification of biomass raw materials. Background technique [0002] my country is rich in agricultural surplus resources, and most of the harvested straws are piled up for storage, which is easy to cause fire and poses a safety hazard. Even if it is burned centrally, it will also cause serious environmental pollution. At present, straw and other biomass raw materials are made into fuel blocks to replace coal as a new type of fuel, which solves the problems of air pollution caused by straw burning in rural areas and lack of coal resources. [0003] A kind of straw rolling forming machine disclosed as CN200910016137.5 as the patent application number adopts the contact surface of two ring dies with ring die holes as the extrusion working surface, fed by the hopper above the extrusion working surface, and the two The ring dies rotate each ...
