Fixing device of heat transfer rhombus pipe in vacuum drying equipment

Technical Field

The utility model relates to a heat transfer diamond tube in vacuum drying equipment, in particular to a fixing device of the heat transfer diamond tube in the vacuum drying equipment.

Background

The traditional crop drying method at present mainly comprises the following steps: the hot air is led to pass through the particles of the crops under normal pressure to evaporate the water, but the drying method leads the crack rate of the crops to be higher, the intrinsic quality of the crops to be easily damaged, the energy consumption to be high, and the tunnel dryer for drying by the hot air has lower heat energy utilization rate of only 30 to 40 percent. The heat energy utilization rate of various drying devices utilizing indirect conduction and radiation combined heat supply is higher than that of a hot air convection dryer by 60-80%, but the utilization of the heat energy is only simple one-time use, energy is wasted, and the energy consumption is high.

In order to improve energy efficiency, some manufacturers adopt vacuum drying, firstly, the drying tank is pumped into a certain vacuum degree, then diamond-shaped pipes for heat exchange are arranged in the drying tank in a layered and spaced mode, an external heat source provides a heat medium to flow in the diamond-shaped pipes, crops in the drying tank are dried through the pipe walls of the diamond-shaped pipes, however, at present, the diamond-shaped pipes adopt steel pipes, the connection mode of the steel pipes and the drying tank is welding, and a phenomenon of weld cracking exists in the use process, so that sealing is not tight, and the drying effect is affected.
