The specific embodiment

See also Fig. 1 to Fig. 3, vacuum drier of the present utility model is that a body 10 is provided with a drying section 20 and a condensing unit 30, but body 10 is established the chamber door 11 of an open and close at drying section 20, wherein:

This drying section 20 is extremely shown in Figure 5 as Fig. 3, be in the position of body 10 towards chamber door 11, be separated out several storage tanks 21, in storage tank 21, place the material disc of placing for material 22, empty shape in being between the storage tank 21, the airtight hothouse 23 of inner formation, each hothouse 23 is in preceding, the rear sidewall is made as and connects sidewall 231, connect on the sidewall 231 and be equipped with blasthole 24, adjacent is provided with the apopore 25 of aperture less than

blasthole

24,23 of hothouses are gone up the flow deflector 26 that weldering is provided with several pieces inclinations, spacing between each flow deflector 26 is a passage flow duct 261, each flow deflector 26 is mutual form, respectively through the difference end with before, company's sidewall 231 welding at rear are fixing, make 231 spaces that form turn of tidal stream road 262 of company's sidewall of flow deflector 26 other ends and hothouse 23, cause the current that enter by blasthole 24 through each flow deflector 26 passage flow duct 261,262 in turn of tidal stream road is connected in series the continuous zigzag that forms and flows out apopore 25.And each blasthole 24 all connects an entry arm 241, apopore 25 connects exit branch 251, each entry arm 241 is communicated with a main oral siphon 242, each exit branch 251 is to connect to be flowed to a main return duct 252, main oral siphon 242 1 ends are connected with a water pumper 28, the water inlet end of water pumper 28 is to be connected with a boiler 27, boiler 27 1 sides are provided with the heater 271 to the water heating, boiler 27 connects the main return duct 252 of water supply circulating reflux elsewhere, main return duct 252 is established the control valve 253 of a control water capacity of returns near the end that leads to boiler 27.

This condensing unit 30 as shown in Figure 1 and Figure 2, it is an evaporimeter 34 that is connected with hothouse 23, evaporimeter 34 1 outputs connect a compressor 31, a condenser 32, an expansion valve 33, are recycled to evaporimeter 34.Evaporimeter 34 two outputs in addition connects one respectively in order to the catchment cistern 37 of usefulness of the vavuum pump 35 and of extracting dry air out, the magnetic valve 36 of one control water storage is installed between cistern 37 and the evaporimeter 34, cistern 37 another opposite ends connect a draining valve 38 in order to the control draining, to form vacuum drier.

The utility model in use, material is placed on the material disc 22, and material disc 22 places in storage tank 21, closes upper chamber door 11, start vavuum pump 35 and begin to carry out drying, in the action, the water heating in 271 pairs of boilers of heater 27, hot water pumps to main oral siphon 242 by water pumper 28, shunting enters water arm 241, enter hothouse 23 through blasthole 24, at first ground floor hothouse 23 is understood first full water, but each layer hothouse 23 is full of hot water gradually.And the hot water that enters hothouse 23 flows out apopores 25 slowly through passage flow duct 261 and turn of tidal stream road 262, because the water conservancy diversion of flow deflector 26, add that apopore 25 apertures are less than blasthole 24, control is gone into the water yield greater than the water yield state, and control valve 253 can be adjusted main return duct 252, and to send into the recirculation water quantitative change of boiler 27 little, so can significantly slow down the rate of circulating flow of current in hothouse 23, make the hot water in the hothouse 23 carry out drying to the material in the material disc 22 full and uniformly.And hothouse 23 apopores 25 flow out the backflow hot water of exit branch 251, send in the boiler 27 through main return duct 252, and this is the desiccation of hot water circuit.

Secondly, steam in the hothouse 23, is water through condensing unit 30 with devaporation, and dry air discharges dry air when vavuum pump 35 vacuumizes, and water is then when magnetic valve 36 controls are unlatching, flowing to cistern 37 stores, be stored into and a certain amount ofly promptly be discharged to desired location by draining valve 38, finish drying operation after, take out materials by material disc 22 and get final product.

The utlity model has following advantages:

1. by the hot water circuit of hothouse, allow hot water with the kenel of face material disc be carried out all Heat, and water temperature is gentle average evenly, makes the material drying effect that is heated very rapid and even.

2. the utility model is provided with flow deflector in hothouse, and blasthole and apopore hole The footpath has different sizes, to postpone the flow velocity of water, increases the time that hot water rests on hothouse, Can control capacity of returns by control valve therebetween and be assisted a ruler in governing a country, increase the hot water time of staying, strengthen the oven dry effect Really.

3. the utility model utilizes the recycling of boiler, can take full advantage of water resource, no Be same as the kenel of directly material being dried heating, significantly save electric power energy.

In sum, the utility model improves fully owing to adopt novel space structure design The shortcoming that prior art exists, a fine piece of writing that meets progressive, dark tool practicality meets beyond doubt New patent application important document is so file an application in accordance with the law.
