Abstract
Closed vacuum hot-air dry system is made of water condenser, low-temperature condenser, vacuum tank, air cleaner, blower fan, radiator, control valve, vacuum equipment and the thing that is dried.Characteristics of the present invention are to carry under one's arms after the hot blast of moisture content flows out from vacuum tank 1, be divided into two parts, a part is through water condenser and low-temperature condenser, another part is behind control valve, mix with hot blast again by water condenser and low-temperature condenser, drive by blower fan 5, through radiator 6, Returning vacuum container.Because the present invention is an enclosed, therefore be not subjected to humidity effect in the extraneous atmosphere, shortened drying time, reduced cost, improved product quality.
Description
The present invention relates to a kind of drying equipment, particularly be used for the drying equipment of products such as dry transformer, transformer.
Before the present invention, existing vacuum hot-air dry device is an open type, when heating, hot blast communicates with ambient atmosphere, therefore be subjected in the extraneous atmosphere temperature effect very big, the moisture content in the thing that is dried can not be removed effectively, thereby the requirement of modern electric product high-performance, high-quality and high reliability can not be satisfied.
Purpose of the present invention provides a kind of closed vacuum hot-air dry system.
The present invention includes vacuum tank 1, condenser 2, air cleaner 3, condenser 4, blower fan 5, radiator 6, control valve 7, the thing 8 that is dried, vacuum equipment 9.
Main points of the present invention, be when system carries out the hot blast heating to the thing 8 that is dried, hot blast circulates in this system, and another main points of the present invention are to carry under one's arms after the hot blast of moisture content flows out from vacuum tank 1, be divided into two partly, a part of through condenser 2 coolings, through condenser 4 removal moisture content, another is partly through control valve 7 again, mix with hot blast again, driven by blower fan 5 by condenser 2, condenser 4.
Employing the present invention can remove the moisture content in the thing that is dried effectively, and irrelevant fully with extraneous atmosphere, thereby has shortened the time of whole dry run widely, and too amplitude reduces product cost, has improved the quality and the performance of the product that is dried.
The principle that the hot blast of the moisture content of carrying under one's arms that flows out from vacuum tank 1 need be divided into two parts is: 1, because the power of condenser 2 and condenser 4 can not be too big, if the hot blast rate that passes through is excessive, then condenser temperature rises too high, and can have a strong impact on the effect of moisture content condensation; 2, owing to the hot blast temperature that enters radiator 6 can not be too low, therefore the hot blast that flows out from vacuum tank 1 is told a part, by condenser 2 and condenser 4, and by control valve 7.By mixing with hot blast again behind the control valve 7, so just can guarantee to have uniform temperature by the hot blast of radiator 6 by condenser 2 and condenser 4.The ratio of two parts can be regulated by control valve 7 according to process condition.
Fig. 1 is a closed vacuum hot-air dry system fundamental diagram of the present invention.
Now the invention will be further described in conjunction with the accompanying drawings, and vacuum tank 1 can be according to user's needs design, certain profile and the size of manufacturing.Condenser 2 is a water condenser, by user's water supply network, and the cooling of supplying water.Condenser 4 is a low-temperature condenser, and its low-temperature receiver is supplied with by refrigeration unit, and minimum operating temperature can reach-10 ℃.Air cleaner 3 is made up of filtering material, is used to filter the dust in air that enters this system.Blower fan 5 is a high-temperature blower, can carry out under higher temperature.Blower fan 5 is connected with this system, and employing flexibly connects, so that the installation of pipeline and maintenance.The thermal source of radiator 6 is steam and electricity, the air that passes through in order to heating.Control valve 7 is a vacuum valve, the hot air flow that passes through in order to adjusting.Vacuum equipment 9 can be according to the different needs setting.
Except that blower fan 5, being connected of each parts and pipeline in the system, all adopt rubber sealing, flange connects, to guarantee the facility of sealing and installation, maintenance.
When this system carried out the hot blast heating to the thing 8 that is dried, hot blast circulated in this system.The hot blast of moisture content carried under one's arms flows out from vacuum tank 1, and a part is removed contained moisture content in the hot blasts through condenser 4 again through condenser 2 coolings; Another part mixes with hot blast by condenser 2, condenser 4 behind control valve 7.Mixed hot blast is driven by blower fan 5, is warming up to technological temperature through radiator 6, enters in the vacuum tank 1 again, to thing 8 heating that are dried, so constantly circulates, and adds the carrying out of vacuum process, till the water content of the thing 8 that will be dried drops to required standard.
When system works is changed by vacuum program thermotropism fetch preface, need in system, to put into atmosphere, the gas of putting into is removed dust through filter 3, again behind condenser 2 and condenser 4 removal moisture content (this moment, control valve 7 place paths were turned off), drive by blower fan 5, radiator 6 heating enter in the system.With the method, guarantee that entering this intrasystem gas reaches higher dried level.
Behind whole vacuum hot-air dry end-of-jobs, need the thing 8 that is dried is lowered the temperature, cooling is adopted and is forced the type of cooling, be that radiator 6 is progressively lowered the temperature by technological requirement, blower fan 5 drives the wind of having lowered the temperature, the thing 8 that is dried is forced cooling, until reaching technological requirement.This forced cooling mode is raised the efficiency more than three times than the natural type of cooling of present employing.
Claims (2)
1, closed vacuum hot-air dry system, comprise vacuum tank 1, condenser 2, air cleaner 3, condenser 4, blower fan 5, radiator 6, control valve 7, thing 8 and vacuum equipment 9 are dried, it is characterized in that: after the hot blast of the moisture content of carrying under one's arms flows out from vacuum tank 1, be divided into two partly, a part of through condenser 2 and condenser 4; Another partly behind control valve 7, with by condenser 2 and condenser 4 that partly hot blast mix, by blower fan 5 drivings, through radiator 6, Returning vacuum container 1.
2, closed vacuum hot-air dry system according to claim 1 is characterized in that the pipeline between condenser 2 and the condenser 4 is provided with air cleaner 3.
