Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, freeze dryer of the present utility model, comprises freeze-drying chamber 1 and cold-trap chamber 5, is provided with the coil pipe 8 for freezing in cold-trap chamber 5; In freeze-drying chamber 1, be provided with support plate 2 and the polylith freeze-drying plate layer 3 that is positioned at support plate 2 tops, the top in freeze-drying chamber 1 is provided with the lifting actuator 4 for driving support plate 2 and freeze-drying plate layer 3 liftings, and the lifting actuator 4 in the present embodiment is oil cylinder.When work, the bottle that is the state of partly jumping a queue completes after freeze-drying on freeze-drying plate layer 3, support plate 2 and each freeze-drying plate layer 3 are just done descending motion under the drive of lifting actuator 4, each freeze-drying plate layer 3 is drawn close mutually and carried out tamponade, and the plug on bottle is pressed in bottleneck completely; 2 of support plates drop to the bottom in freeze-drying chamber 1 so that freeze-drying plate layer 3 is supported.Freeze-drying chamber 1 is positioned at the top in cold-trap chamber 5, between freeze-drying chamber 1 and cold-trap chamber 5, is communicated with by the through hole 9 of being located at 1 bottom, freeze-drying chamber; As shown in Figure 2, in the time that support plate 2 drops to 1 bottom, freeze-drying chamber under the drive of lifting actuator 4, through hole 9 can be covered, realize the isolation in freeze-drying chamber 1 and cold-trap chamber 5.
In the present embodiment, freeze-drying chamber 1 and cold-trap chamber 5 are separated by an overall chamber, entirety is provided with the dividing plate 6 that overall chamber is separated into freeze-drying chamber 1 and cold-trap chamber 5 in chamber, and dividing plate 6 lateral arrangement are so that freeze-drying chamber 1 is up and down and arranges with cold-trap chamber 5, and 9 of through holes are opened on dividing plate 6.When coil pipe 8 is defrosted, freeze-drying chamber 1 and cold-trap chamber 5 need to be isolated, the bottom that now can drive support plate 2 to drop to freeze-drying chamber 1 by lifting actuator 4 contacts with dividing plate 6, and through hole 9 is covered.So, when support plate 2 both can be used for tamponade, freeze-drying plate layer 3 was supported, can be used as again the valve of freeze-drying chamber 1 and cold-trap chamber 5 break-makes; Lifting actuator 4 provides driving power while being both used in tamponade, can be used as again freeze-drying chamber 1 and drive with the valve of cold-trap chamber 5 break-makes.
In the present embodiment, dividing plate 6 is horizontally disposed, so that support plate 2 can contact cooperation better with dividing plate 6 while dropping to the bottom in freeze-drying chamber 1.
In the present embodiment, the bottom of support plate 2 is equiped with the sealing ring 10 coordinating for contacting with dividing plate 6, to ensure the reliability of isolation, and can in the time that support plate 2 contacts with dividing plate 6, provide suitable buffering.
In the present embodiment, the bottom in cold-trap chamber 5 is provided with discharge outlet 7; When work, the condensed water that freeze-drying chamber 1 and cold-trap chamber 5 produce all from then on discharge outlet 7 discharge.
Embodiment 2:
As shown in Figure 3 and Figure 4, the present embodiment is substantially the same manner as Example 1, difference is only: in the present embodiment, lifting actuator 4 is located at the bottom in cold-trap chamber 5, in the time that support plate 2 drops to the bottom in freeze-drying chamber 1 and covers through hole 9, lifting actuator 4 applies downward pulling force to support plate 2, order about support plate 2 and be pressed in through hole 9 peripheries, thereby obtain more excellent seal isolation effect, can measure more accurately the voltage rise in freeze-drying chamber 1, precisely judge whether fully (freeze dryer is mainly by the water evaporates in mixture in bottle in freeze-drying, before tamponade, need to seal freeze-drying chamber 1, and the voltage rise of measuring freeze-drying chamber 1, if freeze-drying chamber 1 pressure is the state of obvious rising, in explanation bottle, the moisture content in mixture still has lasting evaporation, thereby need further freeze-drying, otherwise in explanation bottle, the moisture content in mixture is fully evaporated, can enter tamponade action, complete the sealing of bottle).In addition, above top layer freeze-drying plate layer 3, be provided with upper limit plate 11, move upward when lifting actuator 4 drives support plate 2, compress when spacing until the bottle of the superiors moves to by upper limit plate 11, complete the tamponade of all bottles.Lifting actuator 4 is hydraulic push rod, the cylinder part of this hydraulic push rod is positioned at cold-trap chamber 5, can shorten like this collapsing length of push rod, ensure the stationarity of tamponade action, in other embodiments, also the cylinder body of hydraulic push rod can be located at outside cold-trap chamber 5, can be reduced like this hydraulic push rod taking cold-trap chamber 5 volumes, thereby can suitably dwindle cold-trap chamber 5, reduce complete machine and take up room.Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
