Flow guiding device for heat pump drying box

Abstract

The invention provides a flow guiding device for a heat pump drying box. The flow guiding device comprises the drying box as well as a front flow guiding plate, a back flow guiding plate and an upper flow guiding plate which are arranged inside the drying box; an air inlet and an air outlet are formed in the upper part and the lower part of the front wall of the drying box respectively; the back flow guiding plate and the upper flow guiding plate are mounted on the back side and the upper side of the inside of the drying box respectively; the upper flow guiding plate is located below the air inlet; the drying box is separated into an air inlet channel and a drying area by the back flow guiding plate and the upper flow guiding plate; and air outlet holes are formed in the back flow guiding plate and / or the upper flow guiding plate. By the aid of the flow guiding device, hot air in the drying box can be uniformly distributed, the drying uniformity of the drying box for a to-be-dried material can be guaranteed, the drying efficiency of the drying box can be improved, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of drying treatment, in particular to a flow guiding device for a heat pump drying box. Background technique [0002] With the development of agricultural production and industrialization equipment, indoor drying technology has become an indispensable means to promote the process of agricultural industrialization. In traditional agricultural production, when drying crops such as medicinal materials, rice, vegetables, and fungi, drying, electric heating, or gas heating are often used. These traditional drying methods not only have a long drying cycle and are easy to cause Deterioration of crops due to under-drying or over-drying. [0003] CN203561172U discloses an air source heat pump drying system, comprising a main body of a drying room, a heat pump, an internal circulation fan, and a dehumidification fan. Controller control. The system simply divides the main body of the drying room into a return air ch...

AI Technical Summary

Problems solved by technology

The system simply divides the main body of the drying room into a return air channel and a drying area. This simple separation will lead to uneven distribution of hot air in the drying room, which cannot ensure that the crops can be dried evenly; and the The hot air flow of the drying system is in the way of bottom in and top out, which can easily cause cold air to gather under the drying area, resulting in low drying efficiency
