A kind of bamboo pretreatment device and method

Abstract

A bamboo pretreatment device and method, comprising a hollow cylindrical tube and a supporting device, a heating tank is arranged inside the hollow cylindrical tube, a safety valve is arranged on the hollow cylindrical tube, a door with a water inlet is installed at one end of the hollow cylindrical tube, The other end is provided with a rear end cover with a water outlet; the door is provided with a valve core device, and the first round pipe with a water stop valve is installed on the water inlet, and the water outlet is connected with the outlet pipe with a water outlet valve. A temperature controller is also arranged in the cylindrical tube, and the power line of the heating tank is connected with an external power supply through the temperature controller. The bamboo is treated by the principle of cold and hot bath method to kill insect eggs and mold; this process is divided into two stages of preservative heating and cooling; the remaining cooling water is heated for steam treatment to improve the anti-cracking ability of bamboo. The device has a simple structure, can pretreat the bamboo, and has good treatment effect, short period and low cost.

Description

technical field [0001] The invention relates to a material processing device and method, in particular to a bamboo pre-processing device and method. Background technique [0002] Bamboo pretreatment methods mainly include physical and chemical methods. The principle of the physical method is to remove the nutrient source in the bamboo or transform the nutrient source into inedible substances, or to cut off the moisture and air required for the life of decaying bacteria and insects. Its advantages are low processing cost, simple operation, and generally no pollution to the environment. The disadvantage is that it has no lasting protection. Once the treated bamboo is further processed or wears or cracks, decay bacteria will attack the bamboo again under certain circumstances. , so the physical method is generally not used alone. The principle of the chemical method is to use preservatives to hinder the basic metabolism of fungi, so as to achieve the purpose of inhibiting the...

AI Technical Summary

Problems solved by technology

Its advantages are good anti-corrosion effect and long residual effect time. The disadvantage is that the anti-corrosion treatment operation is complicated, the treatment cost is high, and preservatives generally have certain adverse effects on people and the environment.

The commonly used bamboo chemical anti-corrosion treatment methods mainly include normal pressure impregnation method and adding (reducing) pressure injection method. ) The pressure injection method improves the rate and depth of impregnation, but it is not economical enough for bamboo, because the price of bamboo itself is relatively low, and when processing the whole bamboo, it is prone to cracking, and the distribution of the agent is not uniform, which is very difficult. rarely reach the surface
