Summary of the invention
The purpose of this utility model is to provide a kind of structure optimization, and operating cost is low, utilizes heat pump techniques to generate hot blast, good energy-conserving effect, and can realize the heat pump pulsation dryer that the material pulsation is dried.
For achieving the above object, the utility model adopts following technical scheme:
Heat pump pulsation dryer, this dryer has drying chamber, the drying chamber inner bottom part is provided with the carrying web plate, the below of carrying web plate is provided with rotating gas distributor, gas distributor is communicated with a thermal insulation air channel, and the other end of thermal insulation air channel connects the air outlet of drying chamber, down the wind embeds successively to connect evaporator with heat pump and heat pump condenser on a close end of drying chamber air outlet of thermal insulation air channel, be provided with blower fan in the thermal insulation air channel, described drying chamber is provided with dog-house and discharging opening.
Such scheme further is: a side of described drying chamber also be provided with can absorb solar energy and to the oven dry heating indoor solar panels.
Such scheme further is: described gas distributor is installed in the rotating shaft, and rotating shaft connects motor by gear drive.
Such scheme further is: also be provided with moisture exhausting port for subsequent use on the described drying chamber.
Such scheme further is: described rotary shaft hollow, and inner port is communicated with drying chamber, and outside the external port pass-out drying chamber, forms the discharging opening of drying chamber; Be provided with the blowing rod of the discharging opening that can close and open drying chamber in the inner port of rotating shaft.
Such scheme further is: motor is buncher.
The utility model passes through optimizing structure design, utilize the high temperature heat pump technology to generate hot blast, temperature rise is fast, efficient is high, effectively reduce the consumption of electric power energy, reduce use cost, greatly satisfy the drying work demand, adopt heat pump dehumidifying and fluidized drying combination, have the advantages such as the particle size range that adapts to material is wider, heat and mass speed high, energy-saving effect is obvious in fluidized drying, so that dry material is more even, solar panels absorb solar energy heating in addition, also shorten to the full extent the dry time, thereby saved the energy.
A utility model again advantage is simple in structure, and is scientific and reasonable, easily makes, and cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, greatly improved operation ratio and the operability of equipment.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Figure 1, the heat pump pulsation dryer that the utility model provides, this dryer has drying chamber 1, drying chamber 1 inner bottom part is provided with carrying web plate 2, the below of carrying web plate 2 is provided with rotating gas distributor 3, gas distributor 3 connects a thermal insulation air channel 4, the other end of thermal insulation air channel 4 connects the air outlet of drying chamber 1, on a close end of drying chamber air outlet of thermal insulation air channel 4, down the wind embed successively and connect evaporator with heat pump 5 and heat pump condenser 6, be provided with blower fan 41 in the thermal insulation air channel 4, described drying chamber 1 is provided with dog-house 11 and discharging opening 12.
