Abstract
The invention relates to a high-temperature heat pump drying device. The inner part of a drying box body is divided into two partitions which are a heating chamber and a drying chamber, i.e. a heat absorbing evaporator in the drying box body is arranged in the heating chamber to form a heating mechanism absorbing heat in outside air by regarding the evaporator as a center and continuously providing the heat to a condenser through working media and form a circulating system which heats materials through a circulating fan in the sealed drying chamber by regarding the condenser as the center so that water in the materials is steamed. When the relative humidity reaches a set value, the heating mechanism can automatically remove moisture and feed the hot air without moisture back to the evaporator for secondary afterheat absorption so that the temperature of a heat pump reaches 85 DEG C. The invention has the advantages of high precision, stable performance, simple setting, convenient operation and numerous energy source saving by adopting a high-tech PLC (Programmable Logic Controller) digital temperature and humidity controller and introducing French (KIMO) sensing equipment and a large touch screen human-machine operating panel so that some oily and sugary medicines difficult to dry are better dried.

The specific embodiment
For further understanding summary of the invention characteristics of the present invention and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 5.
Principle of the present invention is as shown in Figure 4: make the hot-air of environment enter evaporimeter 5 by circulating fan 9, evaporimeter 5 absorbs heat, by compressor 6, working medium is the hot gas of crossing of HTHP, pass to condenser 11, in the drying chamber 3 of sealing, circulating fan 9 is given the material on the bin 12 again the heat of condenser 11.Because evaporimeter 5 is not in the drying chamber 3 of sealing, it is the heat in the absorbing environmental always, cold air is constantly discharged by axial flow blower 4, forming one is the unidirectional absorption heat circulation at center with evaporimeter 5, pass through compressor 6 continually to condenser 11 heat supplies, temperature in the sealing drying chamber 3 is constantly risen, and maximum temperature generally is controlled at 85 ℃.Meet consumers' demand fully; In the drying chamber 3 of sealing, after material was heated, the moisture content vaporization constantly increased the hot-air water capacity of closed circulation, when reaching the humidity of setting, by wet-emitting blower 17 and hydrofuge passage 18 in the material.Outwards hydrofuge simultaneously, can replenish the new air of part again from circulation air inlet 10, to prevent causing negative pressure in the case.
As shown in Figure 1-Figure 3: be divided into two partitions in the drying baker casing 1, one of them is heat supply chamber 2, another is a drying chamber 3, the top of described heat supply chamber 2 is provided with axial flow blower 4, the bottom is provided with evaporimeter 5, compressor 6 and throttling arrangement 7, heat supply chamber 2 communicates with condenser 11 by the working medium in the copper pipe, form in the heat supply chamber 2 with evaporimeter 5, compressor 6 is the independent heat circulating system at center, in this system, axial flow blower 4 continuous air draughts, make surrounding air and constantly enter evaporimeter 5 from the hydrofuge waste heat in hydrofuge air channel 18, fin in the evaporimeter 5 constantly absorbs heat wherein, and heating is the bronze pan tube of one with fin, thus the working medium (cold-producing medium) in the heating tube, become the hot gas of crossing of HTHP again through compressor 6, enter condenser 11, and the cold humid air of process steamer 5 is discharged outside the casees with axial flow blower 4.In order to make full use of heat energy, hydrofuge air channel 18 is installed in evaporimeter 5 before, both reclaimed the waste heat in the hydrofuge, again cold moisture is got rid of outside the case, reach the purpose of the continuous feedway of thermal source; The top of described totally enclosed drying chamber 3 is provided with circulating fan 9, circulation air inlet 10, condenser 11, the lower end is fixed with multi-layer material frame for conveying 12, the both sides of bin 12 are fixed with respectively with the A baffle plate 13 of many row of horizontal pore 19 and B baffle plate 14, the bottom of drying chamber 3 is provided with wet-emitting blower 17 and hydrofuge passage 18 with 2 places of communicating, heat supply chamber, form in the drying chamber 3 with condenser 11, bin 12, hot air circulation air channel 15 is the independent material heating circulation system in center, in the material heating circulation system, condenser 11 obtains the hot working fluid of sending here from compressor 6 excessively endlessly, by the fin on the bronze pan tube heats cold condenser 11, pass through air in the circulating fan continuous heating, drying chambers 39 again, material constantly is heated, and make moisture in the material become steam to enter in the air, air self cooling humidification, when airborne humidity reaches setting relative humidity, start wet-emitting blower 17, with automatic hydrofuge.In order to guarantee that temperature is even in the drying chamber 3, the two ends of described evaporimeter 5 and condenser 11 are connected with throttling arrangement 7 with compressor 6 respectively, form systemic circulation; As shown in Figure 2: be fixed with the windscreen 16 of which floor different length up and down in the outside near the baffle plate 13 of 15 inlet sides, hot air circulation air channel, after circulating fan 9 is transported to hot air circulation air channel 15 with the hot blast of condenser 11, hot blast is in flow process, by length different each windscreen 16 and A baffle plate 13, circulate through bin 12 and B baffle plate 14, make air-flow parallel, and make in the drying chamber 3 temperature everywhere with charging tray, air quantity is consistent, to guarantee the high-quality of product; In order to get rid of the cold humid air in the drying chamber 3 smoothly, circulation air inlet 10 is set, when hydrofuge, owing to produce negative pressure in the drying baker casing 1 above drying chamber 3, the air inlet 10 that then circulates is opened automatically, replenish new air,, make gas temperature decline to some extent temporarily in the case because new air is come in, can facts have proved, do hydrofuge helpfully like this, it is faster that inner water evaporates is got, and product quality is better.
Electrical control of the present invention is adopted the conventional PLC numeral temperature and humidity controller 20 that is fixed on 2 belows, heat supply chamber, and is introduced France's (KIMO) sensing equipment, and large-scale touch-screen human-machine operation panel 21.
