Manufacturing process of high-quality bamboo biomass machining rod

Abstract

The invention discloses a manufacturing process of a high-quality bamboo biomass machining rod. The manufacturing process comprises the steps as follows: a, air-seasoning and fermenting fresh bamboos for 30-40 days; b, conducting primary grinding, roller heating and drying and regrinding to fermented bamboos in sequence; c, quickly conducting extrusion molding to reground powder materials by an extruder at the high temperature of 450-500 degrees centigrade; d, processing molded bamboo biomass into the rod. Compared with a prior art, in the manufacturing process, pure bamboo biomass as the raw material is used for processing the residual bamboo biomass machining rod, air-seasoning and fermenting are adopted, heat extrusion molding is conducted according to melting temperature of original ingredients of the bamboo; no binders are added, the bamboo grain size is controlled for quick extrusion molding at the high temperature totally according to the material property; the machining rod extruded is high in molding rate, not easy to break off, uniform in shape and steady in dimension. The carbon rod fired has hard texture and high burning value without fume, odor and toxicity during burning and use.

Description

technical field [0001] The invention relates to an extrusion method of an environment-friendly pure bamboo biomass machine-made stick, in particular to a manufacturing process of a high-quality bamboo biomass machine-made stick. Background technique [0002] In the face of increasingly prominent problems such as the crisis of fossil energy fuels and the destruction of the global ecological environment, the development of renewable biomass clean energy has become the main direction of the development of the world's energy economy. my country is a big producer of biomass resources, rich in various biomass resources, such as crop straw and forestry residues. The traditional utilization methods of these biomass resources are direct combustion or open burning, which not only causes the disadvantages of low energy conversion efficiency and large resource consumption, but also has a subtle impact on the environment. [0003] Mechanism charcoal is a new type of charcoal developed b...

Problems solved by technology

In order to pursue the high molding rate of carbon rods, short and easy to ignite, domestic and foreign production mechanism carbon, some igniters and binders are added when extruding the rods to prepare the rods. Harmful chemical substances may be produced when used during combustion, and there are certain potential safety hazards in use

Secondly, in order to pursue the beauty of the rod body, the unreasonable design of the shape and size and the unreasonable process used are also the main reasons for the uneven quality of the extruded rods, which are fragile, easy to break, and have insufficient drop strength.

[0006] In the current production process of biomass machine-made rods, in order to pursue a short production cycle, many processes use fresh bamboo to dry and then directly carry out hot extrusion. The fermentation of bamboo is not in place, which leads to poor quality of the rods produced.

There are also fresh bamboo chips that are dried and then added with binder. Although such rods are well formed and beautiful in appearance, there is no guarantee that the binder will undergo chemical reaction and recombination during the carbonization process to produce harmful substances, which is safe for the use of carbon rods. caused certain dangers
