Waste heat recovery device of day lily drying machine

Abstract

The invention discloses a waste heat recovery device of a day lily drying machine, and belongs to the technical field of waste heat recovery devices of day lily drying machines. The waste heat recovery device comprises a heat insulation shell, two opening and closing doors are rotatably connected to the front side of the heat insulation shell, and a discharging mechanism is arranged on the inner side wall of the heat insulation shell. When the drying machine is used for drying day lily, in the hot air circulation process, a conversion mechanism is used for cooling hot air, redundant temperature is converted into electric energy to be stored, redundant heat is collected, and the situation that too high air flows back to pass through a heat supply machine and enables the heat supply machine to be overheated is avoided; and the air flow with part of energy after cooling is conveyed into a heat delivery machine again to be heated again, heat loss caused by direct discharge of the hot air flow is avoided, energy consumption of the heat delivery machine is saved, after drying is completed, the hot air flow in the heat insulation shell is pumped out through a draught fan and converted into electric energy through a heat exchanger again, and waste heat is recycled to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of a yellow flower dryer waste heat recovery device, in particular to a yellow flower dryer waste heat recovery device. Background technique [0002] Day lily, also known as day lily, lemon day lily, forget worry grass, belongs to the order of Liliaceae, a perennial herb of Liliaceae, the root is nearly fleshy, and the middle and lower parts often have spindle-shaped swelling. Carbohydrate, protein and fat account for 60%, 14% and 2% respectively in every 100g of dried daylily. In addition, the content of phosphorus is higher than that of other vegetables. The flowers of day lily have the effects of invigorating the stomach, clearing the breast, and nourishing the blood, as well as strengthening the brain and anti-aging effects, because they are rich in lecithin, which is the substance of many cells in the body, especially brain cells. Components that play an important role in enhancing and improving brain ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a yellow flower dryer waste heat recovery device to solve the problem in the prior art that when the day lily is dried in the prior art, it is necessary to make the hot air flow inside the dryer dry during the drying process. Convection, so that during the drying process of the dryer, part of the hot air flow higher than the outside air is lost; and after the drying is completed, a large amount of residual heat inside the dryer is directly discharged into the air , the problem of wasting energy
