As further improvement of the utility model:
Described freeze-drying chamber and cold-trap chamber are separated by a whole chamber, are provided with the dividing plate that whole chamber is separated into freeze-drying chamber and cold-trap chamber in the described whole chamber, and described through hole is opened on the dividing plate.
Described dividing plate is horizontally disposed.
The bottom of described support plate is equiped with to contact with dividing plate the sealing ring of cooperation.
The bottom in described cold-trap chamber is provided with discharge outlet.
Be provided with the coil pipe for refrigeration in the described cold-trap chamber.
During described freeze-drying flaggy tamponade, described support plate drops to the bottom in freeze-drying chamber and covers through hole so that the freeze-drying flaggy is supported.
Compared with prior art, advantage of the present utility model is:
1, freeze dryer of the present utility model, its freeze-drying chamber is positioned at the top in cold-trap chamber, compact conformation, take up room little;
2, freeze dryer of the present utility model, be communicated with by through hole between its freeze-drying chamber and the cold-trap chamber, and can cover the isolation that realizes freeze-drying chamber and cold-trap chamber by general who has surrendered's through hole under the support plate, so the break-make between freeze-drying chamber and the cold-trap chamber can realize by support plate and lifting actuator, no longer need to arrange independently on-off valve and valve oil cylinder, thereby simplified structure, reduce cost, the pollution risk of avoiding the valve oil cylinder to bring, and design, manufacturing, examination, cost control, control program of making freeze dryer etc. all are optimized;
3, freeze dryer of the present utility model, its freeze-drying chamber and cold-trap chamber are separated by a whole chamber, compressible space, save manufactured materials, and freeze-drying chamber and cold-trap chamber can share and import and export pipeline, safety valve and discharge outlet.
Description of drawings
Fig. 1 is the structural representation of the utility model when freeze-drying chamber and cold-trap chamber are in connected state.
Fig. 2 is the structural representation of the utility model when freeze-drying chamber and cold-trap chamber are in isolation.
Marginal data: 1, freeze-drying chamber; 2, support plate; 3, freeze-drying flaggy; 4, lifting actuator; 5, cold-trap chamber; 6, dividing plate; 7, discharge outlet; 8, coil pipe; 9, through hole; 10, sealing ring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
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 refrigeration in the cold-trap chamber 5; Be provided with support plate 2 and the polylith freeze-drying flaggy 3 that is positioned at support plate 2 tops in the freeze-drying chamber 1, the top in freeze-drying chamber 1 is provided with for the lifting actuator 4 that drives support plate 2 and 3 liftings of freeze-drying flaggy, and the lifting actuator 4 in the present embodiment is oil cylinder.During work, be the bottle of false add plug state after freeze-drying flaggy 3 is finished freeze-drying, support plate 2 and each freeze-drying flaggy 3 are just done descending motion under the drive of lifting actuator 4, each freeze-drying flaggy 3 is drawn close mutually carried out tamponade, are pressed into the plug on the bottle in the bottleneck fully; 2 of support plates drop to the bottom in freeze-drying chamber 1 so that freeze-drying flaggy 3 is supported.Freeze-drying chamber 1 is positioned at the top in cold-trap chamber 5, is communicated with by the through hole 9 of being located at 1 bottom, freeze-drying chamber between freeze-drying chamber 1 and the cold-trap chamber 5; As shown in Figure 2, when 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 a whole chamber, be provided with the dividing plate 6 that whole chamber is separated into freeze-drying chamber 1 and cold-trap chamber 5 in the whole chamber, dividing plate 6 lateral arrangement arrange that 9 of through holes are opened on the dividing plate 6 so that freeze-drying chamber 1 is up and down with cold-trap chamber 5.When coil pipe 8 is defrosted, freeze-drying chamber 1 and cold-trap chamber 5 need be isolated, can drive the bottom that support plates 2 drop to freeze-drying chamber 1 by lifting actuator 4 and contact with dividing plate 6 this moment, and through hole 9 is covered.So, when support plate 2 both can be used for tamponade freeze-drying flaggy 3 was supported, can be used as the valve of freeze-drying chamber 1 and cold-trap chamber 5 break-makes again; Lifting actuator 4 provided driving power when both being used in tamponade, the valve that can be used as freeze-drying chamber 1 and cold-trap chamber 5 break-makes again drives.
In the present embodiment, dividing plate 6 is horizontally disposed, so that support plate 2 can contact cooperation better with dividing plate 6 when dropping to the bottom in freeze-drying chamber 1.
In the present embodiment, the bottom of support plate 2 is equiped with to contact the sealing ring 10 that cooperates with dividing plate 6, with the reliability that guarantees to isolate, and can provide suitable buffering when support plate 2 contacts with dividing plate 6.
In the present embodiment, the bottom in cold-trap chamber 5 is provided with discharge outlet 7; During work, the condensed water that freeze-drying chamber 1 and cold-trap chamber 5 produce is discharge outlet 7 discharges from then on all.
Below only be preferred embodiment of the present utility model, protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
