Integrated condensation type heat pump drying equipment

Abstract

The invention relates to the technical field of drying equipment, in particular to integrated condensation type heat pump drying equipment which comprises an equipment body, a partition plate is placed in the equipment body, and air return equipment is arranged at the top ends of the two sides of the partition plate; the air return equipment comprises a shell fixedly connected with an equipment body, two filtering structures are arranged in the shell, a discharging structure is arranged at the bottom of each filtering structure, and a power structure is arranged in the shell. When the filtering device works, two rotating cleaning wires can be used for cleaning crushed leaves or fluff attached to a fine filtering net into a rotating shell, the cleaning wires can shake when colliding with an arc piece, impurities clamped on the cleaning wires are shaken into the rotating shell, and then when the rotating shell is vertical, the impurities are discharged into a discharging structure, so that the impurities are discharged into the fine filtering net through the discharging structure. Therefore, automatic cleaning work of broken leaves or fluff is completed, the ventilation effect is improved, and manual cleaning is not needed.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an integrated condensation heat pump drying equipment. Background technique [0002] The heat pump dryer is a new type of drying device, which mainly uses the reverse Carnot principle. The gas Freon is pressurized by the compressor to become a high-temperature and high-pressure gas (temperature up to 100°C), and enters the indoor heat exchanger (condenser). The condensed and liquefied refrigerant releases high-temperature heat to heat and dry the air in the room. The materials in the drying room vaporize and evaporate the moisture in the materials in the form of hot air, and the evaporated water vapor is discharged by the dehumidification system to achieve the purpose of drying the materials. After condensing and releasing heat, the refrigerant turns into a low-temperature and low-pressure liquid through the throttle valve. Due to the sudden drop in pressure, the liquid...

Problems solved by technology

[0003] At present, when the heat pump dryers on the market are drying flowers, the lint or fallen leaves will flutter with the hot wind, and then adhere to the air inlet side of the return air filter. Beginning to gradually affect the ventilation effect, it is necessary to manually enter the equipment to clean the return air filter and clean the lint in the dust box after shutting down every day, so as to ensure good ventilation and make the equipment play the best drying effect, which is time-consuming and laborious , affecting production efficiency, so there is an urgent need for a device that can automatically remove impurities adhering to the air inlet side of the return air filter during work to ensure the ventilation effect, and can automatically discharge impurities from the box without manually entering the device. An integrated condensing heat pump drying equipment for impurity cleaning
