Solar energy type dryer

Abstract

The invention discloses a solar energy type dryer. The solar energy type dryer comprises a machine frame, solar heat collecting pipes, a main box body, a motor, a sealing pipe, a blade, supporting legs, drying discs, a water storing layer, a heat preservation layer, a tightening button, a door, a water filling pipe, a humidity sensor, an active buzzer, and a ventilation opening. Compared with theprior art, the solar energy type dryer has the beneficial effects that the solar heat collecting pipes are arranged to use solar energy to heat water in water storing layer, so that energy is saved, and the environment is protected; the heat preservation layer is arranged outside the water storing layer, aluminum alloy cooling fins are used for the inner wall; materials can be dried with heat dissipated by hot water and airflow generated by rotation of the blade; the humidity sensor is arranged in the main box body; and after drying, the buzzer sends an alarm to promote a user.

Description

technical field [0001] The invention relates to a dryer, in particular to a solar dryer. Background technique [0002] The dryer has several modes such as belt drying, drum drying, box drying, and tower drying; the heat source includes coal, electricity, gas, etc.; the drying process of materials has hot air flow type and radiation type, etc. , hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and makes full use of the heat transfer through heat conduction, convection, and radiation; the heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder, and the material is fed into the cylinder. The air-introduction device at the outlet draws out a large amount of water and wet air to prevent secondary pollution caused by dust discharge; through internal spiral stirring, sweeping, and lifting, the material is pushed forward to complete the entire dryin...

AI Technical Summary

Problems solved by technology

[0003] Existing dryers generally use fuel or electric energy for heating, which not only causes energy waste, but also may cause environmental pollution. The reduction of drying efficiency, and even the over-drying of materials, cause economic losses
