Abstract

The utility model discloses a bamboo chip oil heat treatment kiln. The bamboo chip oil heat treatment kiln comprises a central cavity with a circular cross section, an oil cavity with a circular annular cross section and a sealing door. The oil cavity with the circular and annular cross section is filled with oil. The central cavity with a circular cross section can be used for the inlet and the outlet of the pressure tank. Cutting raw bamboo into bamboo chips with width of 20-50mm, removing green and yellow, and placing in a pressure tank side by side; then the pressure tank is pushed into a central cavity with a circular cross section, and the door is closed to form a closed space; then heating the oil, and controlling the temperature within 90-245 ℃. The bamboo chips treated by the kiln have uniform color and luster, stable size, and corrosion and mildew resistance.

Description

Bamboo chip oil heat treatment kiln

Technical Field

The utility model belongs to bamboo timber processing field involves a bamboo chip oil heat treatment 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.

Disclosure of Invention
