A pretreatment device for anti-cracking tung oil process of bamboo and wood

Abstract

The invention discloses a pretreatment device for bamboo and wood cracking prevention tung oil technology. The pretreatment device for the bamboo and wood cracking prevention tung oil technology comprises a conveying belt, a sprayer is arranged above the conveying belt and connected with an oil pump, the oil pump is connected with an oil inlet pipe at the bottom of a tung oil tank, a constant-temperature water tank is arranged outside the tung oil tank, and an opening type tung oil recovery tank is arranged at the lower bottom of the conveying belt and flows back to the tung oil tank. The pretreatment device has the advantages that the pretreatment device is simple in structure, low-temperature tung oil only needs to be sprayed onto bamboo and wood products to be boiled, the constant-temperature water tank is arranged outside low-temperature tung oil, the consistency of the temperature of the low-temperature tung oil is guaranteed, the tung oil recovery tank is directly arranged below the conveying belt under the sprayer, an existing production line cannot be affected, and process transformation can be finished.

Description

Technical field [0001] The invention relates to the technical field of bamboo and wood products processing technology, in particular to a pretreatment device for bamboo and wood anti-cracking tung oil technology. Background technique [0002] For bamboo and wood products that are easy to crack, the use of tung oil cooking can make the tung oil more fully soak into the wood, so that the wood is not easy to crack, and the consistency is better. However, it is actually found that some wood cracks. The important reason is that the wood is cracked. Into the high-temperature oil, the sudden high temperature caused the wood to crack, which accelerated the cracking of the wood. Therefore, it is necessary to modify the existing process production line and install a tung oil pretreatment device on the production line to crack the wood. Reduce it further to prevent it from cracking when it enters the oil. Summary of the invention [0003] In view of the deficiencies in the prior art, the pu...

[0002] For bamboo and wood products that are easy to crack, 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 has better consistency. However, it is actually found that some wood cracks. The important reason is that when the wood When entering the high-temperature oil, the sudden high temperature causes the wood to crack, which accelerates the cracking of the wood. Therefore, it is necessary to modify the existing process production line, and install a pre-treatment device for cooking tung oil on the production line to reduce the cracking of the wood. further lowered to prevent cracking when it enters the oil
