Abstract

The invention discloses a biomass fuel block production method and equipment. Straw is cut into blocks, rubbed in a straw rubbing machine, extruded in a biomass fuel movable mold forming machine at certain temperature to fill up a movable mold, placed in a heat insulation bin for 2-5 min at the temperature of 190 DEG C or above for shaping and then subjected to demolding. According to the straw rubbing machine, an auger and a rubbing head are matched to carry out rubbing, the fiber structure of the straw is compressed, the size is reduced, density is increased, and therefore the material feeding quantity in the forming machine is increased. According to the biomass fuel movable mold forming machine, the movable mold is adopted, a movable mold track and the heat insulation bin are additionally arranged, a choke pipe in an extruding machine is omitted, a shaping pipeline in a shape keeping area is shortened, frictional force between materials and the mold and loss of the mold are reduced, cost is lowered, and energy consumption is saved; the mold is automatically transferred into a heat insulation device after being filled, the extruding machine continues to operate, production time for a single fuel block is shortened, shape keeping time is prolonged, and the produced biomass fuel blocks are good in shape, high in density, uniform in texture and consistent in specification.

Description

technical field [0001] The invention belongs to the technical field of biomass fuels, and in particular relates to a method for producing biomass fuel blocks, and a straw extruding machine, a biomass fuel living mold forming machine and a biomass fuel production system for realizing the method. Background technique [0002] In recent years, due to the improvement of rural living standards, farmers' dependence on straw crop fuel has decreased, resulting in a large amount of crop straw remaining every year, which has brought a lot of trouble to straw disposal and spring plowing production in the coming year. Due to the thin soil layer of the cultivated land and the large investment in farming, it is difficult to implement the deep plowing and returning of straw to the field, and discarding and piling up takes up a lot of cultivated land resources. Therefore, farmers mostly use direct burning of straw. However, burning straw not only has the risk of causing fires, but also caus...
