Device for improving quality of plant materials through hot pressing

Abstract

The invention discloses a device for improving the quality of plant materials through hot pressing and belongs to the technical field of machining. Based on the composition of the plant materials and chemical and physical properties, proper heating is adopted for softening lignin to improve plasticity of the plant materials, the proportions of space occupied by various gaps such as cavity hole concaves of the plant materials is reduced through pressurizing, density and strength of the plant materials are improved, and the quality of the plant materials is greatly improved. Low-quality plant materials become good-quality plant materials high in density and high in strength. The problems about ecological environment protection, reduction and stopping of cutting of forests especially good-quality forests and the requirement of economic society development and people life for a large amount of good-quality wood are solved, meanwhile, comprehensive, good-quality and efficient utilization of agricultural and forestry byproducts is achieved, the problem that straw leaves pollute the atmosphere environment is solved, and wide and low-cost application of high-density and good-quality plant materials becomes feasible. The device can also be used for town and country construction and treating of slag mucks and the like or common soil and stone materials can be used for manufacturing various building materials and buildings such as slate bar tables, chairs, kiosks and bridges and the like.

Description

technical field [0001] The invention relates to a material processing technology device, in particular to a heat-pressing plant material quality improvement device which uses heating and pressing processing technology to improve plant material quality and use and commercial value. Background technique [0002] Plant material refers to the material material produced in the process of plant life. For example, wood, tree branches and leaves, straw, etc. [0003] At present, there are many types of known plant material processing technologies. Mainly direct and indirect processing and utilization. Direct processing, such as wood processing, cotton spinning, etc. Indirect utilization, such as papermaking, artificial cotton, etc. Different plant compositions require different methods of processing and utilization. For example, the composition of wood cells can be divided into two major and minor components, the main components are cellulose, hemicellulose and lignin; the mino...

Problems solved by technology

[0011] In order to overcome the difficulty of existing plant material processing technology to solve the economic and social development and improvement of living conditions, the demand for plant materials such as wood is increasing. Over-harvesting of forests, the scarcity of high-density high-quality wood is difficult to meet the demand, and the direct combustion of plant materials releases a large amount. Greenhouse gas and smog pollute the environment, a large number of by-products of plant crops cannot be fully utilized or even cannot play a role. The present invention provides a processing technology based on the composition and chemical physical properties of plant materials, using appropriate heating and pressure. A heat-pressing plant material quality improvement device that reduces the volume of various voids, such as cell cavity depressions, in the plant material, increases its density and strength, and can greatly improve its quality.
