Tung oil thermal treatment automatic production line for bamboo and wood products

Abstract

The invention discloses a tung oil thermal treatment automatic production line for bamboo and wood products. The automatic production line comprises a conveyor belt which is used for conveying the bamboo and wood products and passes through a pretreatment station, an oil stewing station, an aftertreatment station and a recovery station arranged on the aftertreatment station in sequence. A tung oil pool and a heater for oil stewing of the bamboo and wood products are arranged on the oil stewing station. The recovery station comprises a recovery oil pump connected with a filter tank. The recovery oil pump delivers oil back into the tung oil tank through an oil return pipe. According to the tung oil thermal treatment automatic production line, through the arrangement of the pretreatment station, the phenomena that the bamboo and wood products crack are greatly reduced through low-temperature pretreatment; the interiors of timbers are fully soaked with tung oil through oil stewing of the high-temperature tung oil tank; through hot wind, low temperature and cold wind stepped temperature reduction, the surface treatment quality of bamboo products is effectively improved, and the cracking phenomena are further reduced; and a settling tank and the filter tank are arranged on an oil collection pipe, the quality of recovered oil products is greatly improved, and recovered oil directly flows back into the tung oil tank.

Description

technical field [0001] The invention relates to the technical field of oil treatment technology for bamboo and wood products, in particular to an automatic production line for heat treatment of bamboo and wood products with tung oil. Background technique [0002] Cooking with tung oil can make the tung oil soak into the wood more fully, so that the wood is not easy to crack and the consistency is better, but it is actually found that there are still some problems: [0003] First of all, part of the wood cracks. The important reason is that when the wood enters the high-temperature oil, the sudden high temperature causes the wood to crack and accelerates the cracking of the wood. Therefore, it is necessary to modify the existing process production line and install a The pre-treatment device for tung oil boiling can further reduce the cracking of wood and prevent it from cracking when it enters the oil. [0004] Secondly, limited by the existing technology, only part of the o...

Problems solved by technology

[0004] Secondly, limited by the existing technology, only part of the oil attached to the surface of bamboo and wood products after boiling can be recovered, and most of them are treated as waste oil, causing serious waste. many

[0005] Thirdly, due to the high temperature in the oil treatment workshop, the lubricating oil on the conveying chain of the conveying mechanism dries quickly, and the use of a lubrication system with an oil pump has high equipment and maintenance costs; It is easily damaged, and the maintenance of the existing technology is inconvenient; the positioning of the conveying mechanism of the prior art is inconvenient, and additional binding is required by workers; therefore, it is necessary to develop a self-lubricating conveying mechanism with low cost, simple maintenance, convenient positioning, and good conveying effect
