Abstract
The utility model relates to a pneumatic door lock mechanism for vacuum freeze drying machines. The utility model is mainly composed of an air source, air cylinders and double electric control electromagnetic valves, wherein, a pneumatic control system is composed of the air source, the air cylinders and the double electric control electromagnetic valves; a plurality of air cylinders are distributed and arranged at a door frame of a freeze drying box; piston rods of the cylinders are provided with lock bolts; the corresponding positions of a door of the freezing and drying box are provided with lock catches a plurality of air cylinders are also distributed and arranged at a door frame of a freeze drying box; the corresponding positions of a door of the freezing and drying box are provided with lock catches The utility model has the advantages of simple structure, convenience, practicability, balanced operation, low noise and large thrust, is suitable for automation of door opening / closing of large-scale freezing dryers, and is especially suitable for the freezing dryers used for steam sterilization.
Description
The utility model relates to a kind of vacuum freeze drier pneumatic door latch mechanism.
The freeze-drying tank gate of conventional vacuum lyophilizer safe locking when moise-heat sterilization is to bear the immense pressure from steam.After steam disinfection finishes, need SC when opening the door, prevent that the steam of remnants in the freeze-drying tank from going out, cause the accident.Therefore, the common handwheel locking mechanism complicated operation that just seems, poor stability.
The purpose of this utility model is to provide vacuum freeze drier pneumatic door latch mechanism a kind of simple in structure, convenient and practical.
For achieving the above object, the utility model is taked following design proposal: this vacuum freeze drier pneumatic door latch mechanism, mainly form by source of the gas, cylinder and two automatically controlled solenoid valve, described source of the gas, cylinder and two automatically controlled solenoid valve are formed pneumatic control system, several cylinder distribution apparatus are on the door of freeze-drying tank, on the piston rod of described cylinder, install dead bolt, corresponding position device snap close on the freeze-drying tank doorframe.Certainly, also can be on the doorframe of freeze-drying tank with several cylinder distribution apparatus, and on the freeze-drying chamber door corresponding position device snap close.
Because the utility model adopts above technological scheme, in the time of need locking a door, open source of the gas, it is electric that the 1DT of two automatically controlled solenoid valves is got, and cylinder pushes snap close with dead bolt, reaches the locking purpose; In the time of need opening the door, make the 1DT dead electricity of two automatically controlled solenoid valves, 2DT gets electric, and cylinder is drawn back dead bolt, and the gate is unlocked.Therefore, the utility model is simple in structure, and is convenient and practical, the operation balance, and noise is low, and thrust is big.Be applicable to the automation of large-scale freeze dryer opening-closing door, be particularly useful for the freeze dryer of moise-heat sterilization.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model one embodiment's schematic representation
As shown in Figure 1, this vacuum freeze drier pneumatic door of the utility model latch mechanism, mainly form by source of the gas 1, cylinder 2 and two automatically controlled solenoid valve 3, described source of the gas 1, cylinder 2 and two automatically controlled solenoid valve 3 are formed pneumatic control system, several cylinder 2 distribution apparatus are on the door 5 of freeze-drying tank 4, device dead bolt 7 on the piston rod 6 of described cylinder, corresponding position device snap close 8 on freeze-drying tank 4 doorframes.Certainly, also can be on the doorframe of freeze-drying tank with several cylinder distribution apparatus, and on the freeze-drying chamber door corresponding position device snap close.
In the time of need locking a door, open source of the gas 1, it is electric that the 1DT of two automatically controlled solenoid valves 3 is got, and cylinder 2 pushes snap close 8 with dead bolt 7, reaches the locking purpose; In the time of need opening the door, make the 1DT dead electricity of two automatically controlled solenoid valves 3,2DT gets electric, and cylinder 2 is drawn back dead bolt 7, and the gate is unlocked.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.
