Straw puffing machine

Abstract

The invention relates to a straw puffing machine. A disintegrating guide rod is a double-helix guide rod, the lead of the disintegrating guide rod is gradually reduced from a feed inlet to a dischargeoutlet, and the bottom diameter of the disintegrating guide rod is gradually increased from the feed inlet to the discharge outlet. The outer contour of the disintegrating guide rod is of a cylinder.The bifilar-helix design of the disintegrating guide rod makes the equipment convey materials stably, mechanical energy is converted into heat energy, and heat generated by friction is rapid and uniform. Compared with conventional puffing machines, the straw puffing machine has the advantages that compression of the radial force is decreased, the noise is reduced, the service life of the equipment is prolonged, the materials are discharged smoothly, the yield is increased, and the quality of end products is improved. The disintegrating guide rod of the straw puffing machine pushes the materials toward the discharge outlet along with the gradually shallow helical line, and the materials rub and squeeze a spiral sleeve to be broken. High temperature and high pressure are generated during operation, water molecules are rapidly expanded, and the materials are instantaneously sprayed, disintegrated and puffed by a disintegration ring. Compared with the conventional puffing machines, the straw puffing machine has the advantage that the yield is increased by 30% on the basis of the same power.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw puffing machine. Background technique [0002] my country is a big country in agriculture and animal husbandry. The annual production of 900 million tons of crop and plant straw is not effectively utilized, and most of them are abandoned or burned. At the same time, a large amount of edible straw in herbivorous animal husbandry is abandoned, which not only causes waste of resources, but also leads to serious environmental pollution. Crude fiber, lignin and other herbivorous livestock and poultry in the straw are difficult to digest and absorb, and the cellulose hemicellulose and lignin in the straw are closely combined to form crystals, which further affects the digestibility of herbivorous livestock and poultry. And the burning of a large number of straws has caused serious air pollution, which has always been a worldwide pain point. Traditional straw treatment mos...

Problems solved by technology

And the burning of a large number of straws has caused serious air pollution, which has always been a worldwide pain point

The traditional straw treatment mostly adopts techniques such as guillotine sectioning and shredding, which do not change the internal molecular structure of the straw. Its characteristics are low utilization rate, difficult to digest and absorb, and difficult to store and transport.

[0003] The existing straw puffing machines still have the following problems: 1. At present, domestic straw processing equipment has not reached the level of cellulose crystal disintegration, resulting in a very low conversion utilization rate of straw

2. The material guide rod and the disintegration guide rod of the traditional straw puffing machine adopt a single-wire integrated screw to convey the material, which belongs to one-sided transmission, and the ...
