Abstract
The utility model relates to a thick bamboo tube heat treatment sand kiln belongs to bamboo timber processing field. The bamboo tube heat treatment sand kiln comprises a sand cavity with a rectangular and annular middle cross section, a central cavity with a rectangular cross section and a sand cavity door with a rectangular cross section. Two rails are arranged in the central cavity with the rectangular cross section for the trolley to walk. The rectangular annular sand cavity and the sand cavity door are filled with sand. The raw bamboo tubes cut into fixed length can be placed in a trolley side by side after bamboo joints are removed along the whole length; pushing the trolley into a central cavity with a rectangular cross section along the track, and closing the sand cavity door to form a closed space; all the sand is then heated. Setting different temperatures for heat treatment according to different purposes of the bamboo wood.
Description
Technical Field
The utility model belongs to the bamboo timber processing field relates to a thick bamboo tube heat treatment sand kiln.
Background
Bamboo is produced in China, the quantity and quality of bamboo are at the top of the world, the bamboo can be regenerated and degraded, the bamboo can be made into wood in 3-5 years generally, the tensile strength of the bamboo is about 2 times of that of the wood, the compressive strength of the bamboo is about 1.5 times of that of the wood, the specific strength of the bamboo is higher than that of common wood, structural steel, aluminum alloy, concrete and the like, the bamboo has better elasticity and toughness and strong deformability, and the bamboo and composite materials formed by the bamboo and other materials can replace concrete, steel or clay bricks and the like to construct houses.
The untreated raw bamboo tube contains starch, reducing sugar, protein, fat, mineral substances and the like in the internal components, can provide sufficient nutrient substances for various bacteria, fungi and moths, and ensures that the bamboo and products thereof are easy to mildew in the processes of storage, transportation, processing and use. The quality of the product is affected by the damage of fungus rot and worm damage, and the use value is reduced or even completely lost.
Therefore, the antiseptic treatment of the original bamboo tube is very important, and the heat treatment is one of the very important ways.
