Description

Vacuum drying chamber
Technical field
The utility model relates to a kind of Drug processing equipment, particularly relates to a kind of vacuum drying chamber.
Background technology
Vacuum drying chamber is widely used in the industries such as medicine, food, light industry, chemical industry and does low temperature drying.Vacuum drying dried material is in the heat drying carried out under vacuum condition, and it utilizes vavuum pump to carry out bleeding dehumidifier, makes to form vacuum state in operating room, reduce the boiling point of water, accelerate rate of drying, can be at a lower temperature, obtain higher rate of drying, Btu utilization is abundant.
As shown in Figure 1, existing vacuum drying chamber adopts jet chimney heating, vacuumizes mode drying under reduced pressure.During work, after opening vavuum pump, drying box negative pressure constantly reduces, and in vacuum drying chamber, the stream cream of basin is taken away with vacuum pipe because heating moisture becomes steam, and stream cream moisture content is constantly reduced.Along with vacuum drying chamber negative pressure constantly reduces, more and more close to vavuum pump limiting value, the pressure reduction between vavuum pump and drying box diminishes, thus diminish from the vapor (steam) velocity that drying box enters vacuum pipe, now, stream cream easy bumping under negative pressure high temperature, go out basin, pollute drying box.This just causes drying time long, and baking temperature is high, and energy consumption is large, the situations such as inefficiency.
Utility model content
The purpose of this utility model is to provide the vacuum drying chamber that a kind of drying efficiency is high, energy consumption is low.
In order to achieve the above object, the utility model vacuum drying chamber comprises casing, basin, steam-heated pipe line, vacuum pipe and water circulation vavuum pump; Described steam-heated pipe line is arranged on basin; Described vacuum pipe is positioned at casing top and is connected with water circulation vavuum pump; Condensing reflux EGR is provided with vacuum pipe junction in casing.
Described condensing reflux EGR comprises cool cycles waterpipe; The circulating water intake of described cool cycles waterpipe, circulating water outlet stretch out casing and connect inlet channel and drainage pipeline respectively outward; Condensation-water drain is provided with bottom described condensing reflux circulating water device.
Also comprise fluid reservoir; Described fluid reservoir is positioned at casing outside, and its top is provided with entrance and is connected by pipeline with the condensation-water drain bottom condensing reflux EGR.
Be provided with outlet bottom described fluid reservoir, this outlet is connected with circulating water intake pipeline.
Cool cycles waterpipe in described condensing reflux EGR is provided with fin.
Adopt structure of the present utility model, by increasing cool cycles waterpipe and condensed fluid collection fluid reservoir in vacuum drying chamber, can greatly increase moisture drying speed, reduce steam-heated consumption, and the time that vavuum pump is opened, greatly save the energy, improved working condition, reduced production cost and improve production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 2, vacuum drying chamber of the present utility model comprises casing 1, basin 3, steam-heated pipe line 4, vacuum pipe 7 and water circulation vavuum pump 8.Steam-heated pipe line 4 is arranged on basin 3.Vacuum pipe 7 is positioned at casing 1 top and is connected with water circulation vavuum pump 8.Condensing reflux EGR 9 is provided with vacuum pipe 7 junction in casing 1.This condensing reflux EGR can be the various existing devices with circulating condensing function.
The condensing reflux EGR 9 that the utility model provides comprises cool cycles waterpipe 13.Circulating water intake 10 and the circulating water outlet 11 of cool cycles waterpipe 13 stretch out outside casing 1, and connect inlet channel and drainage pipeline respectively.Condensation-water drain 12 is provided with bottom condensing reflux circulating water device.
In order to the condensed water flowed out bottom condensing reflux circulating water device can be utilized, fluid reservoir 14 can also be comprised.It is outside that fluid reservoir is positioned at casing 1, and its top is provided with entrance and is connected by pipeline with the condensation-water drain bottom condensing reflux EGR.
Be provided with outlet bottom fluid reservoir, this outlet can be connected with circulating water intake pipeline.Outlet bottom fluid reservoir 14 and can arrange by-pass valve control between circulating water intake pipeline, can realize recycling of recirculated water, using water wisely like this.
In order to improve condensation effect, the cool cycles waterpipe in condensing reflux EGR can be provided with fin.
During work, after open water circulation vacuum pump 8, drying box casing 1 negative pressure constantly reduces, and in casing 1, the stream cream 5 of basin 3 is taken away with vacuum pipe 7 because heating moisture content becomes steam, and stream cream 5 moisture content is constantly reduced.Along with casing 1 negative pressure constantly reduces, more and more close to water circulation vavuum pump 8 limiting value, pressure reduction between water circulation vavuum pump 8 and drying box casing 1 diminishes, thus diminish from the vapor (steam) velocity that drying box enters vacuum pipe 7, now, stream cream 5 temperature raises and easy bumping, by adding condensing reflux circulating water device 9 in casing 1, and increases condensation water collection fluid reservoir 14.Vapours in casing 1 is cooled, avoid stream cream 5 because temperature raise and bumping, maintain the baking temperature in casing, to be differently from former drying box is maximum, steam is met cool cycles waterpipe 13 and is liquefied as water droplet, enter fluid reservoir 14, the same in room refrigeration as air-conditioning, when constant temperature, the humidity also constantly in minimizing casing 1, liquefaction water droplet, thus greatly improve drying box drying efficiency.
