Drying system achieving heating through air source heat pump

Abstract

The invention discloses a drying system achieving heating through an air source heat pump. The drying system comprises the air source heat pump device and a drying device which communicates with the air source heat pump device. The drying device comprises a drying box and a material box which is arranged in the drying box. The bottom of the material box is provided with a plurality of supporting springs. A vibration motor is arranged between the supporting springs. An output shaft of the vibration motor is connected with a rotating shaft through a coupler, and the rotating shaft is connected with a cam. When the drying system is used, a compressor is started to work, an evaporator can absorb a great amount of heat from the outside when carrying out evaporation, then, a condenser works, a great amount of heat is released and is pumped to the drying box through a draught fan, and compared with traditional electrical heating and coal heating, the drying system is more efficient and simpler; and in addition, in the process that materials are dried, the vibration motor can be controlled to work, the material box is enabled to vibrate up and down through a cam, in this way, stirring of the materials can be achieved, the materials on the bottom layer can also be dried, and the product quality is higher.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a drying system heated by an air source heat pump. Background technique [0002] Heat pump technology is increasingly mature and widely used in air conditioning, heating, hot water, heat recovery, and drying industries. Heat pump technology is becoming more mature and widely used in air conditioning, heating, hot water, heat recovery, and drying industries. In view of this, Chinese patent (201310565548.6) discloses a closed-loop dehumidification heat pump drying system, which includes: a heat-insulating drying space body, which is isolated from the outside air to form a closed cavity; a tray, placed in the cavity; The tray has a through hole to form an air flow pipe; a heat pump dryer; installed in the cavity, it includes an air outlet, an exhaust fan, a heat pump condenser, The regenerator, evaporator and air inlet are used to form an up-and-down cycle of hot, dry and ...

Problems solved by technology

However, this solution has the following two problems: one is that the heat generated by the heat pump itself is not fully utilized, and it is easy to spread to the outside; the other is that when the materials in the tray are drying, the materials in the tray cannot Turn over, so that the surface layer is often fully dried during drying, and the internal materials cannot meet the drying requirements, which affects the quality of the product
