Description

Multi-chamber divides modus ponens vacuum drying chamber

Technical field

The utility model relates to a kind of multi-chamber point modus ponens vacuum drying chamber.

Background technology

In existing technology pharmaceutical industry, various drying machines, drying box are very important equipment.The raw material of medicinal material or semi-finished product just can carry out follow-up processing after must removing all or part of moisture or solvent wherein and reach technique humidity requirement through drying process, and therefore the quality of drying box performance has determined the dry mass of medicinal material; For medication chemistry laboratory, the vacuum drying chamber drying equipment that is more absolutely necessary, but because the kind of studying in laboratory is more, the drying time of product, baking temperature etc. are widely different, often have the situation of depositing various materials in a drying box to occur, if when now a material need to be removed, need the vent valve of casing to open, casing could be opened after making pressure in whole casing return to normal value, will affect like this drying effect of unclassified stores in casing.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of multi-chamber point modus ponens vacuum drying chamber, the material subregion of different cultivars can be deposited, and only needs to discharge separately the vacuum of certain sub-chamber while picking and placeing, can not affect the drying effect of unclassified stores.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: multi-chamber point modus ponens vacuum drying chamber, comprise casing and vavuum pump, described vavuum pump is positioned at described casing outside, described box house space be divided into front material deposit chamber and after vacuumize chamber, vacuumize after described and on chamber, there is vent valve and the vacuum adapter that can be connected with described vavuum pump;

Described front material is deposited chamber and is divided into four sub-chamber, the corresponding door of each described sub-chamber, on described sub-chamber rear wall, there is switching control pilot, the unlatching of described sub-chamber by described switching control pilot with described after vacuumize chamber and be communicated with, in described sub-chamber, there is humiture inductor and vacuum inductor;

In described sub-chamber, have horizontally disposedly for placing the frame plate of material, described frame plate is engraved structure.

Also comprise electric controller, described electric controller is positioned at described casing outside, and described humiture inductor is all connected with described electric controller with vacuum inductor, and described vavuum pump, described vent valve, described switching control pilot are by described electric controller control.

Further, always there is aqueous water to exist in order to solve in drying box, water vapour just cannot continue liquefaction smoothly, dry process and the problem of effect are directly affected, the bottom of described sub-chamber has groove, the edge of described groove extends to the sidewall of described sub-chamber, and the low spot of described groove has electrical bar, and described electrical bar is by described electric controller control.

Preferably, the cross section of described groove is del.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, having realized the material subregion of different physical properties deposits and takes, avoid influencing each other, the design of unique polycrystalline substance can be got rid of the steam in drying box in time in addition, and drying effect is better.

Fig. 2 is casing part side structure schematic diagram;

In figure: 1-humiture inductor, vacuum inductor; 2-switching control pilot; 3-hollow out; 4-casing; 5-sub-chamber; 6-frame plate; 7-sub-chamber bottom; 8 electrical bars; 9-electric controller; 10-vacuum adapter; After 11-, vacuumize chamber.

The specific embodiment

As shown in the figure, the utility model provides a kind of multi-chamber point modus ponens vacuum drying chamber, comprise casing 4, electric controller 9 and vavuum pump (not shown), electric controller 9 and vavuum pump are all positioned at casing 4 outsides, casing 4 inner spaces be divided into front material deposit chamber and after vacuumize chamber 11, after vacuumize and on chamber 11, there is vent valve (not shown) and the vacuum adapter 10 that can be connected with vavuum pump;

Front material is deposited chamber and is divided into four sub-chamber 5, the corresponding door (not shown) of each sub-chamber 5, on sub-chamber's 5 rear walls, there is switching control pilot 2, the unlatching of sub-chamber 5 by switching control pilot 2 with after vacuumize chamber 11 and be communicated with, in sub-chamber 5, there is humiture inductor and vacuum inductor 1;

In sub-chamber 5, have horizontally disposedly for placing the frame plate 6 of material, frame plate 6 is hollow out 3 structures;

Humiture inductor is all connected with electric controller 8 with vacuum inductor 1, and vavuum pump, vent valve, switching control pilot 2 are by electric controller control.

Always there is aqueous water to exist in order to solve in drying box, water vapour just cannot continue liquefaction smoothly, dry process and the problem of effect are directly affected, the bottom 7 of sub-chamber 5 has groove, the edge of groove extends to the sidewall of sub-chamber 5, the low spot of groove has electrical bar 8, and electrical bar 8 is controlled by electric controller 9.Preferably, the cross section of groove is del.

The course of work of this example: when vacuum drying chamber is opened, vavuum pump starts casing to vacuumize, switching control pilot 2 in each sub-chamber 5 is opened, in the time that vacuum inductor detects that vacuum reaches requirement, electric controller 9 is closed switching control pilot 2, in the time that all switching control pilots 2 are all closed, vavuum pump quits work, now vent valve open by after vacuumize vacuum in chamber 11 and discharge.When need to pick and place in some sub-chamber 5 material time, electric controller 9 is opened the switching control pilot 2 in this sub-chamber 5, the pressure in this sub-chamber 5 returns to atmospheric pressure, now can by this sub-chamber 5 door open.

Water in casing flows in the groove of each sub-chamber 5 bottoms after assembling, now water is converted into gas by electrical bar 8, when humidity in humiture inductor detects sub-chamber 5 is excessive, electric controller 9 is closed vent valve, open switching control pilot and vavuum pump in this sub-chamber 5 simultaneously, steam is extracted out, guaranteed the relatively dry in casing.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
