Problems solved by technology

Natural ventilation drying is to directly pass ambient air into the granary for drying. It is simple and practical, but natural ventilation drying has three disadvantages: 1. The drying cycle is long and consumes a lot of high-grade energy; 2. It is greatly affected by the weather; 3. uneven drying
[0005] Through patent search, it is found that the patent application document number CN2935038 records a mobile three-dimensional storage drying device, and a mobile ventilation pipe is arranged on the grain surface. The operation mode of this device can reduce the unevenness of drying, but the labor intensity is high. ; Patent Application Document No. CN2882269 records a kind of grain cooling, storage drying, storage humidification and conditioning all-in-one machine. Effect
In the prior art, there is a lack of a drying treatment device that can achieve safety, high efficiency and energy saving in the drying process on the whole at the same time.

Abstract

The invention relates to an in-store drying process device of a solar-assisted heat pump in the technical field of grain storages, comprising a heating system of the solar-assisted heat pump, an air supply and return system, a ventilation cage-on-the-ground air supply system and a grain-shoveling machine. The output end of the heating system of the solar-assisted heat pump is connected with the input end of the air supply and return system which is connected with an air inlet hole and an air outlet hole of a barn; the ventilation cage-on-the-ground air supply system and the grain-shoveling machine are respectively arranged in the barn; and the ventilation cage-on-the-ground air supply system is connected with the air inlet hole of the barn. The invention can fully utilize solar energy and decrease the energy consumption of the system; the use of the solar-assisted heat pump ensures the safety and the high efficiency of a drying process; and the reasonable use of the ventilation cage-on-the-ground air supply system and the grain-shoveling machine ensures the drying uniformity. Three working modes can be mutually switched to ensure the suitability of the drying system.

Description

technical field [0001] The invention relates to a device in the technical field of grain storage, in particular to a solar-assisted heat pump on-storage drying treatment device. Background technique [0002] Drying plays a very important role in improving the storage conditions of crops and prolonging the storage time of crops. The grain dry collection and storage management mode in my country's agriculture is harvesting, drying, and storage. Due to weather and other reasons, the moisture content of the grain purchased in some areas often exceeds the standard or is too high, and the grain depot must be dried again, otherwise mildew will easily occur after storage, and the entire grain depot will be damaged. [0003] In-silo drying is a grain drying method widely used in Chinese grain depots. This method is to put high-moisture grain directly into the warehouse, use natural or heated air as the drying medium to dry the high-moisture grain with a certain height, and store th...
