Continuous graining machine fuel gas hot air furnace mechanism with dryer

Abstract

The invention provides a continuous graining machine fuel gas hot air furnace mechanism with a dryer. The mechanism comprises a control module, an air temperature adjusting mechanism, drying ovens, ahot air furnace, a hot air output channel and a hot air reuse channel; the hot air output channel communicates with smoke dividing pipes of the drying ovens; an air outlet of each drying oven communicates with the hot air furnace through the hot air reuse channel; when materials in the drying ovens are dried, hot flue gas output from the hot air furnace enters the drying ovens, and after the materials are heated, cooled air is sent back to the hot air furnace through the hot air reuse channel to be heated again; the control module comprises a PLC; and the air temperature adjusting mechanism comprises temperature sensors connected with the PLC, a D / A converter, an A / D converter and a variable frequency adjustor; and the temperature sensors are arranged at the positions of the drying ovens.The continuous graining machine fuel gas hot air furnace mechanism with the dryer can perform stable heat supplying towards the drying ovens in production of synthetic leather.

Description

technical field [0001] The invention relates to the technical field of heating for synthetic leather, in particular to a gas-fired hot air stove with a dryer mechanism for a continuous kneading machine. Background technique [0002] During the production process of synthetic leather, the air discharged from the oven of the continuous kneading machine has not been recovered reasonably, which increases fuel consumption and causes a certain amount of heat loss. [0003] At present, most of the heating methods used in domestic synthetic leather production are centralized heating by coal-fired heat-conducting oil furnaces. There are also related patents on the natural gas heating technology for synthetic leather, but in the actual transformation process, there are many equipments and processes. The changes are large, the transformation period is long, the impact on the original equipment is great, and it is difficult to restore. The key is that in the actual heating process, the...

[0002] During the production process of synthetic leather, the air exhausted from the oven of the continuous kneading machine has not been recovered reasonably, which increases fuel consumption and causes a certain amount of heat loss

[0003] At present, most of the heating methods used in domestic synthetic leather production are centralized heating by coal-fired heat-conducting oil furnaces. There are also related patents on the natural gas heating technology for synthetic leather, but in the actual transformation process, there are many equipments and processes. The changes are large, the transformation period is long, the original equipment is greatly affected, and it is difficult to restore

The key is that in the actual heating process, the hot air is transported to the oven through a long-distance air duct, resulting in unstable temperature of the hot air entering the oven, and the production of synthetic leather has extremely high requirements on temperature stability, and a stable supply is required. Thermal technology; the key is that in the actual heating process, the wind resistance of hot air will increase after passing through many devices, and the air circulation equipment of the original system cannot operate normally, so a heating technology with low wind resistance is required
