Description
The utility model relates to a kind of drying device, particularly relates to a kind of vacuum heat pump drying device.
Drying is a kind of operation of high energy consumption, how to improve efficiency, reduces cost, and improving the quality of products and protecting environment is the focus that current scientific worker both at home and abroad pays close attention to.Adopt electrical heating, steam or hot blast heating in current employed traditional drying device both at home and abroad mostly, its energy consumption is big, the temperature height.Also useful heat pump heats, but in, can not suppress bacterium, microbial growth in the dry run under the cryogenic conditions, influence product quality.Also have vacuum freeze drier, its disadvantage is that energy consumption is big, the cost height.
The purpose of this utility model provides a kind of vacuum heat pump drying device, and it can remedy the above-mentioned deficiency of existing apparatus.
A kind of vacuum heat pump drying device, comprise a drying box, a heat pump assembly inner box-machine is housed in the casing of this drying box, casing is equipped with the heat pump assembly outer box-machine outward, this inner box-machine is connected by pipeline with outer box-machine, it is characterized in that having a water ejector, its throat is connected with valve with pipeline by check (non-return) valve, the other end of valve is connected with casing by pipeline, the inlet of water ejector is connected with the water under high pressure delivery side of pump by pressure piping, and the import of water pump is communicated with water tank by water pipe, connection valve.
The utility model utilizes a water stream injection pump that the part air in the drying box is extracted out, the vacuum that periodically keeps dry in the case is 0-0.01MPa, utilizes heat pump assembly to make the cross-ventilation and the article that are dried carry out heat, matter exchange, and article are carried out drying, can make the article cleaning that is dried, health, quality is good, and less energy consumption, cost is low, reduce environmental pollution, shortened drying time, needing can be widely used in the industries such as food, pharmacy, chemical industry, building materials of low temperature drying.
Below by embodiment and description of drawings the utility model.
The utility model comprises an existing drying box 1, and this drying box 1 has casing 4, and its right-hand member has right end cap 2, right sealing strip 3, and drying cart 5 is arranged in the casing 4, dividing plate 6, and the left end of casing 4 has left sealing strip, left end cap.The airduct frame 9 of an existing heat pump assembly inner box-machine is housed in the casing 4 of drying box 1, evaporimeter 10, blower fan 11, condenser 12, drip tray 13, downpipe 14 and electrical auxiliary heater 15 are housed on this airduct frame 9.This downpipe 14 is in the bottom of casing 4.The heat pump assembly outer box-machine has choke valve 16, by- pass valve control 18,19, moves condenser 17 and compressor 20 outward outside casing 4 above it.Inner box-machine is connected by condenser gas, liquid pipe and evaporimeter gas, liquid pipe with outer box-machine.The utility model has a water ejector 28, its throat is connected with valve 31,32 with pipeline 30 by check (non-return) valve 29, the other end of valve 32 is connected with casing 4 by pipeline 33, and stretch into casing 4 inside, the inlet of water ejector 28 is connected with the outlet of high-pressure hydraulic pump 23 by pressure piping 21, the import of water pump 23 connects valve 25 by water pipe 24 and is communicated with water tank 26, water tank 26 is equipped with drain valve 27, the water outlet of water ejector 28 flows in the water tank 26, valve 31 is cohesion water blowoff valve, and 22 is Water filling valve.Be connected to intake valve 34 on the casing 4.
The utility model is when running, when water ejector 28 is passed through in the draining of high-pressure hydraulic pump 23, the latter's throat produces negative pressure, and the air in the suction dried casing 4, cooperating the vacuum in the casing 4 that periodically keeps dry with intake valve 34 is 0-0.01Mpa, simultaneously the cohesion water that concentrates on drying box 1 bottom that heat pump assembly is separated out under the aspiration vacuum condition.
