Embodiment 1

[0035] Such as figure 1 shown.

[0036] A method for improving biomass compression molding rate, comprising the following steps:

[0037] Firstly, an exhaust passage 2 is set between the molding die 1 and the body of the main molding machine. The main molding machine adopts a hot pressing molding process, and the molding temperature range is 100-200°C. The mouth is connected, and the biomass raw materials (such as wheat straw, rice straw, corn straw, rice husk, forage grass, etc.) of the feed port are heated by the heat of the exhaust channel 2. The moisture content of the biomass raw material ranges from 10% to 25%) for heating;

[0038] Secondly, the vent hole 2 is set on the cavity wall of the shape-preserving section 6 of the molding die 1, and the angle between the center line of the vent hole and the center line of the die hole is less than 90°, preferably greater than or equal to 45°, and less than 90° , the hole diameter is 2-5mm, the angles of the exhaust holes 2 c...

Embodiment 2

[0042] A device for improving the compression molding rate of biomass, which includes a molding die 1, and the installation form of the molding die 1 is as follows figure 2 As shown, a plurality of exhaust holes 3 are arranged on the cavity wall of the shape-retaining section 6 of the molding horizontal 1, and the exhaust holes 3 communicate with the exhaust channel 2, and the exhaust channel 2 is located outside the molding die 1 and Forming between the host body. The angle between the centerline of the vent hole 3 and the centerline of the die hole is greater than or equal to 45° and less than 90°, and the diameter of the hole is 2-5 mm. The angles between the central line of the vent hole 3 and the central line of the die hole are the same or different, and the apertures are the same or different.

[0043] According to the different processes of biomass compression molding, the die hole of the forming mold can be divided into three parts: pre-compressing section 4, formin...

Abstract

The invention relates to the technical fields of agricultural equipment and biomass energy, in particular to a method and a device for improving a biomass compression moulding rate. The device comprises a biomass compression moulding main engine device and a moulding mould provided with vent holes, wherein a vent passage is arranged between the moulding mould with the vent holes and the engine body on which the moulding mould is arranged, so that vent smoothness is ensured. The method and the device have the beneficial effects that production efficiency is high; energy consumption is low; a moulding effect is good; and the method and the device have good adaptability to biomass materials which are difficult to compress and mould, and can be widely applied to the technical field of fodder or biomass moulded fuel processing.

Description

technical field [0001] The invention relates to a biomass raw material processing technology, in particular to a compression molding technology for straw feed or biomass molding fuel raw materials in biomass, in particular to a method and device for increasing the compression molding rate of biomass. Background technique [0002] With the increase of the world's population and the improvement of living standards, the human demand for energy is increasing day by day. Energy shortage and environmental pollution caused by the use of fossil fuels are the greatest challenges facing human society. The development and utilization of renewable energy is the key to solving this problem. Biomass energy, as a renewable energy source, has unique advantages and huge potential for development and utilization. my country produces a large amount of crop straw and forestry waste every year, except for a small part that is recycled, most of which are discarded in the field or buried or dire...
