Embodiment
[0039] like Figure 1-2 As shown (for the convenience of description, the air duct for the variable temperature dryer is drawn in cooperation with the variable temperature dryer 23, and the number of the sub-air ducts is set to six; the distance between the six sub-air ducts and the variable temperature The dryer is named as the first sub-air duct 1, the second sub-air duct 2, the third sub-air duct 3, the fourth sub-air duct 4, the fifth sub-air duct 5, and the sixth sub-air duct 6 from near to far. Correspondingly, the drying sections of the variable temperature dryer 23 are named from top to bottom as the first drying section 7, the second drying section 8, the third drying section 9, the fourth drying section 10, the The fifth drying section 11 and the sixth drying section 12.) In this embodiment, an air duct for a variable temperature dryer is provided, and the air duct for a variable temperature dryer includes a control module and multiple sub-air ducts ,Right now figu...

The invention provides an air duct used for a variable-temperature drying machine and a control method of the air duct and relates to the field of agricultural equipment. By means of a control module, according to sensing values of temperature sensors of a plurality of sub-air ducts, the rotation speed of an air heater, the heat generation rate of a heat source and opening and closing of hot air louvers and air adjusting valves of the corresponding sub-air ducts can be controlled. During full-bin drying and semi-bin drying, it can be guaranteed that the temperature of each drying section is controlled to be at the preset temperature accurately. By means of the air duct used for the variable-temperature drying machine and the control method, the technical problems that in the prior art, semi-bin treatment can be not be achieved through a variable-temperature drying machine, and the temperature of each drying section can not be controlled accurately are solved.
Description
technical field [0001] The invention relates to the field of agricultural equipment, in particular to an air duct for a temperature-variable dryer and a control method. Background technique [0002] The tower dryer used in the grain and seed processing industry has multiple drying sections from top to bottom in the drying chamber. Before drying, the material is fed from the upper part of the dryer, and the material fills the entire dryer from top to bottom. When drying, the material is dried from top to bottom. Due to the different characteristics of the material in each drying section and the difficulty of removing moisture from the material, the drying parameters such as temperature, wind pressure, and wind speed are different in each drying section. After drying, the material is discharged from the outlet at the lower end of the dryer. In practical applications, drying parameters such as wind pressure and wind speed are used as secondary control elements, and generally ...
