The invention relates to the technical field of foam processing, in particular to a foam plastic packing material pre-foaming device and a foaming method thereof.The foam plastic packing material pre-foaming device comprises a base, a pre-foaming cylinder is fixed to the top of the base, and the bottom of the pre-foaming cylinder communicates with an external high-temperature steam generating mechanism through a communicating mechanism. According to the pre-foaming device, pre-foaming materials fully reacted at the bottom of the interior of the pre-foaming cylinder are conveyed upwards through the pre-foaming material conveying and turning mechanism, and in the upward conveying process of the pre-foaming materials, the pre-foaming materials at the bottom of the pre-foaming cylinder flow upwards, so that a certain space is reserved at the bottom of the pre-foaming cylinder; therefore, the pre-expansion materials which are in less contact with high-temperature steam above the pre-expansion cylinder can flow to the space below the pre-expansion cylinder, so that the pre-expansion materials above the pre-expansion cylinder can be fully absorbed and reacted with the high-temperature steam, and the pre-expansion materials at different parts in the pre-expansion cylinder can be fully contacted with the high-temperature steam to be expanded.

A straw indirect carbonization-based soil improvement method and system, the method comprising the following steps: (A) collecting straw, cutting the straw into straw particles; (B) extruding and destroying the surface of the straw particles; (C) using microwave heating to extrude the straw particles, obtaining puffed straw particles; (D) carbonizing the surface of the puffed straw particles, obtaining carbonized particles for discharge into soil. The indirect carbonization method of first breaking the wall and then puffing and carbonizing the surface can significantly reduce the energy consumed during carbonization and shorten the processing time of the straw, which is conducive to the straw carbonization and field application treatment of a large area of soil. At the same time, the surface-carbonized carbonized particles can provide sufficient biomass carbon for the soil, and it is not necessary to remove part of the carbonized particles from the field due to the excessive biomass carbon of the soil. In addition, the carbonized particles also well retain the nutrients in the straw.

This utility model relates to the field of feed processing technology and provides a feed extruder, including a cylinder with support plates fixed on both sides of the bottom end of the cylinder. A screw is installed inside the cylinder, a drive motor is installed on the outer wall of the cylinder at one end of the screw, and a discharge port plate is fixed on the outer wall of the cylinder at the other end of the screw. This utility model features a metering structure. When feed enters the feed hopper, it falls into the metering trough. At this time, a rotating rod rotates, driving the metering trough to rotate via a metering seat. Simultaneously, the rotating rod drives a stirring shaft to rotate via a transmission belt. Under the action of the equally spaced metering troughs, the feed is metered into the cylinder. The stirring shaft drives a stirring rod to stir the feed inside the feed hopper, effectively preventing feed bridging. This device facilitates the prevention of feed bridging, thereby improving the applicability of the feed extruder in use.

The invention discloses a soil improvement method and system based on straw indirect carbonization, and the method comprises the following steps: (A) collecting straw, and cutting the straw into straw particles; (B) extruding and breaking the epidermis of the straw particles; (C) heating the extruded straw particles by using microwaves to obtain puffed straw particles; and (D) carbonizing the surfaces of the puffed straw particles to obtain carbonized particles for being discharged into soil. The indirect carbonization mode of first wall breaking and puffing and then surface carbonization can significantly reduce energy consumed during carbonization, shorten the treatment time of the straw, and facilitate straw carbonization and field returning treatment of large-area soil, meanwhile, carbonized particles with the carbonized surface can provide enough biomass charcoal for the soil, and the soil quality is improved. Part of carbonized particles in the field do not need to be transported out due to the fact that the biomass charcoal exceeds the soil bearing capacity, and nutrient substances in the straw are well reserved by the carbonized particles.
