Flat plate-type dryer based on solar energy

Abstract

The invention discloses a flat plate-type dryer based on solar energy, and belongs to the technical field of drying equipment. The flat plate-type dryer comprises a box body, a light-transmitting cover plate and an absorber plate. A spring separation device is arranged in a drying cavity and connected with a supporting plate. The spring separation device comprises a shell and a piston. One end of the piston is connected with a push rod, and the other end of the piston is connected with an L-shaped pull rod. The push rod penetrates through the shell to be connected with the supporting plate. The L-shaped pull rod is sleeved with a spring. A sliding chute is formed in the side wall of the box body. Limiting bayonets are arranged on the sliding chute. The flat plate-type dryer further comprises a clamping device. The clamping device comprises a U-shaped elastic sheet and an adjusting bolt. The U-shaped elastic sheet is formed by a first clamping piece, a connecting piece and a second clamping piece in an integrated mode. The adjusting bolt is located outside the box body. By the adoption of the flat plate-type dryer, the phenomenon that heat is excessively transmitted to a dried object by the absorber plate can be effectively prevented, and burning of the dried object is avoided. Meanwhile, the dried object can be guaranteed to make good contact with the absorber plate when the amount of heat on the absorber plate is small, and the drying effect and efficiency are ensured.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a flat-plate dryer based on solar energy. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. According to different drying principles, it can be divided into tumble dryer and solar dryer. [0003] The heat source of the tumble dryer comes from the combustion device, and adopts a down-flow heating method. Therefore, the material to be dried slips into the cylinder from the feed box. Since the dryer is placed on an incline, the material flows to the rear end under the action of gravity and rotation on the one hand, and on the other hand, the material is repeatedly picked up by the lifting board and brought to the upper end for furt...

AI Technical Summary

Problems solved by technology

Due to the close contact between the heat absorbing plate and the item to be dried, the distance between the heat absorbing plate and the item to be dried is insufficient, which may easily lead to excessive heat transfer from the heat absorbing plate to the item to be dried. If the personnel do not turn over in time, the dried items will be scorched
