The invention discloses a reed-based biomass rod utilization production system, which includes a chipper, a pulverizer, a drying fan, a dust remover and a granulation device. The granulation device includes a granulation box, and the granulation box starts from the bottom of the An upper cylinder with an opening and a lower cylinder with an opening at the top are composed of a template, a main shaft, a pressing roller and a blade inside the granulation box. The main shaft drives the pressing roller to extrude the reed-based powder, and the reed-based powder passes through the die of the template. The holes are cut into granules by the blade. The granulation device improves the pressing roller, so that the single sheets of the pressing roller can be quickly exhausted, and the guide shaft accelerates the exhaust and enhances the suction of the reed-based powder by the pressing roller. , improve the compactness of reed-based rod-shaped particles, reduce looseness, and improve the production quality and efficiency of reed-based biomass rods.

The invention provides a comprehensive industrial solid waste treatment system and treatment method, including installation base plate, support feet, conveying mechanism, compression mechanism and packaging mechanism. Cloth bundling, a large number of repetitive operations increase the labor intensity of workers, and manual packing is difficult to effectively compress the cloth, so that the density of the cloth in each area of ​​the cloth compression block is consistent, increasing the probability of loosening of the cloth compression block, and more It is difficult to eject the compressed cloth block out of the equipment after packing, and the manual removal operation will easily cause excessive scratches between the compressed cloth block and the side wall of the compression box, resulting in loosening and falling of the cloth.

The invention relates to the field of agricultural planting technology, and discloses a seedling tray for storage and transportation of seedlings, which includes a tray, a liquid hole is opened above the outer wall of the tray, and a pressing plate is connected to the edge of the top of the tray in rotation. The outer wall of the tray is provided with a ring cavity located outside the liquid hole, the bottom of the tray is provided with a base, the bottom of the base is fixedly connected with a main magnetic block, and the inside of the base is provided with a sliding seat. The present invention uses the vibration of the vehicle to continuously transport the nutrient solution into the matrix to ensure the sufficiency of water supply and liquid supply for the seedlings, and at the same time avoid the problem of manual watering during transportation. Atomize the irrigated nutrient solution to reduce the volume of the nutrient droplet, increase the adsorption force between the nutrient droplet and the substrate, slow down the falling speed of the nutrient solution, prolong the contact time between the nutrient solution and the roots of the seedlings, and provide sufficient water for the growth of the seedlings. nutrient.

The invention relates to a drainage asphalt pavement cold seam material and a preparation method and application thereof. The drainage asphalt pavement cold seam material is prepared from 1 part by weight of an aqueous epoxy resin, 1.5 parts by weight of an aqueous epoxy resin curing agent, 50 to 100 parts by weight of anionic emulsified asphalt and 1 to 2 parts by weight of water. The cold seam material has low temperature stability, high temperature stability, good cohesion and water seepage effects, realizes good connection of the original pavement and newly paved pavement, reduces transverse and longitudinal cracks, prolongs a service life of the pavement, has good water permeability and smoothly discharges rain water.

The invention relates to a coaxial cable for use in a shallow sea bed and a manufacturing method thereof. The coaxial cable is characterized in that a high pressure polyethylene insulating layer is extruded outside the inner conductor; an outer conductor is uniformly woven at the periphery of the high pressure polyethylene insulating layer; two layers of polyester film strips are lapped at the periphery of the outer conductor in opposite directions. and the periphery of the polyester film strip is successively coated with a first asphalt coating layer, a first dipped hemp rope lining layer, a second asphalt coating layer, a copper alloy wire armor layer, a third asphalt coating layer, a second dipped hemp rope lining layer, a fourth asphalt coating layer, a aluminum plated magnesium alloy steel wire armor layer, a fifth asphalt coating layer, a first dipped hemp wrapped strip layer, a sixth asphalt coating layer, a second dipped hemp wrapped strip layer, a seventh asphalt coating layer and a plastic film anti-sticking layer.
