All-weather solar dryer

Abstract

The invention discloses an all-weather solar dryer. The part of an upper outlet of a solar heat collector is connected with the upper end of a water storage tank through a pipeline, a lower port of the solar heat collector is communicated with the lower end of the water storage tank via an auxiliary water pump, a furnace body is a cavity with one side open, a heat exchanger is arranged at the open position of one side of the furnace body, one end of the heat exchanger is communicated with the bottom of the water storage tank through a pipeline, the other end of the heat exchanger is communicated with the upper-end liquid level of the water storage tank through a main water pump, a main air blower is arranged in the furnace body and close to the inner side of the heat exchanger, a feed bin is arranged at the top end of the furnace body, a screen is arranged at the bottom of the feed bin, the feed bin and the furnace body are communicated via the screen, and the inlet end and the outlet end of an auxiliary air blower are communicated with an upper port of the feed bin and the bottom of the water storage tank respectively through pipelines. The all-weather solar dryer is an auxiliary electric heater, and can be ensured to be normally used in weather without sunshine.

Description

technical field [0001] The invention relates to a solar drying device, in particular to an all-weather solar drying device, which belongs to the technical field of solar drying devices. Background technique [0002] At present, solar drying devices are widely used in the dehydration and drying of grain, Chinese medicinal materials, agricultural and sideline products, and other products. Strong or weak, the impact of climate change is relatively large, and it cannot realize all-weather production and use in the true sense. [0003] The purpose of the present invention is to provide a new type of all-weather solar drying device for the above-mentioned defects of the existing solar drying device, which overcomes the inability of the existing solar drying device to realize real all-weather drying. production defects. Contents of the invention [0004] The technical solution adopted by the present invention to achieve the above object is: the all-weather solar drying device i...
