Carbonization treatment method and device for mahjong mat bamboo chips

Abstract

The invention discloses a carbonizing treatment method of mahjong mat bamboo chips. The carbonizing treatment method is accurate in temperature, slow in temperature rise and capable of controlling water content of products. The carbonizing treatment method is characterized by including steps: pre-drying, heating-drying, pre-carbonizing, carbonizing, cooling, and discharging. A device comprises a rack which is provided with a furnace and a power mechanism, the furnace comprises an outer barrel and an inner barrel driven by the power mechanism, a feeding and discharging port at one end of the furnace is connected with a mesh-belt dryer through a conveying belt, a steam recycling device is arranged at the feeding and discharging port, and the furnace is connected with a heat-conducting oil furnace provided with an air blower and an oil delivery pump; heat-conducting oil pipes are distributed between the outer barrel and the inner barrel, mounted on the inner wall of the outer barrel by a fixing clamp, communicated with a pipeline and filled with heat-conducting oil, and a temperature sensor is arranged in the inner barrel and connected with a master control console which is connected with the power mechanism, the air blower and the oil delivery pump. The mesh-belt dryer is used, so that water content is reduced and deformation is avoided; defective product rate is low; water steam is collected to prepare bamboo vinegar liquid; the water content of the products meets requirements of being directly used in the next process.

Description

technical field [0001] The invention relates to the preparation of mahjong mats, in particular to a carbonization treatment method and device for mahjong mat bamboo chips. Background technique [0002] Bamboo mats are one of the necessities of human life in summer. There is a mahjong mat made of small bamboo pieces in the shape of mahjong on the market, which is suitable for uneven surfaces such as sofas and Simmons beds. Mahjong mats are made by machine-processing bamboo into small bamboo pieces the size of mahjong blocks. After drilling, frosting, polishing and other processes, elastic connecting ribs are used as warp connectors, and high-strength nylon thin threads are used as weft connectors. Connecting, arranging and weaving a plurality of small bamboo slices in sequence into required size. [0003] The main components of the cell wall of bamboo are mainly composed of cellulose, lignin and hemicellulose, the total of the three is more than 90%, and about 10% of oil, ta...

Problems solved by technology

The defect of this heating method is: because the furnace fuel of the carbonization furnace is bamboo processing residue, the temperature is too high and the heating rate is too high during heating, so it is impossible to operate production in summer; and the quality of bamboo processing residue fuel is different, and the amount of artificial fuel And the rate is also different, so the heat generated is different

Compared with molten salt, another type of high-temperature heat transfer medium, heat transfer oil has an absolute advantage over heat transfer medium in terms of price and service life when the operating temperature is above 400°C, but in other respects it is at a disadvantage. Clear disadvantage, especially with regard to the complexity of system operation
