Summary of the invention
The technical problem to be solved in the present invention is: for the deficiency that prior art exists, provide a kind of simple in structure, with low cost, the freeze dryer little, that pollution risk is low takes up room.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of freeze dryer, comprise freeze-drying chamber and cold-trap chamber, be provided with support plate and the polylith freeze-drying plate layer that is positioned at the support plate top in described freeze-drying chamber, described freeze-drying chamber is provided with for the lifting actuator that drives support plate and freeze-drying plate layer lifting, described freeze-drying chamber is positioned at the top in cold-trap chamber, is communicated with by the through hole of being located at bottom, freeze-drying chamber between described freeze-drying chamber and cold-trap chamber, when described support plate drops to bottom the freeze-drying chamber, through hole is covered the isolation that realizes freeze-drying chamber and cold-trap chamber.
As a further improvement on the present invention:
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 described whole chamber, and described through hole is opened on 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 that coordinates.
The bottom in described cold-trap chamber is provided with discharge outlet.
Be provided with the coil pipe for refrigeration in described cold-trap chamber.
During described freeze-drying plate layer tamponade, described support plate drops to the bottom in freeze-drying chamber and covers through hole so that freeze-drying plate layer is supported.
Compared with prior art, the invention has the advantages that:
1, freeze dryer of the present invention, its freeze-drying chamber are positioned at the top in cold-trap chamber, compact conformation, take up room little;
2, freeze dryer of the present invention, be communicated with by through hole between its freeze-drying chamber and 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 support plate, so the break-make between freeze-drying chamber and 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 costs, 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 invention, 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
The structural representation that Fig. 1 is the present invention when freeze-drying chamber and cold-trap chamber are in connected state.
The structural representation that Fig. 2 is the present invention when freeze-drying chamber and cold-trap chamber are in isolation.
Marginal data: 1, freeze-drying chamber; 2, support plate; 3, freeze-drying plate layer; 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 present invention is described in further detail.
As shown in Figure 1, freeze dryer of the present invention comprises freeze-drying chamber 1 and cold-trap chamber 5, is provided with the coil pipe 8 for refrigeration in cold-trap chamber 5; Be provided with support plate 2 in freeze-drying chamber 1 and be positioned at the polylith freeze-drying plate layer 3 of support plate 2 tops, the top in freeze-drying chamber 1 is provided with for the lifting actuator 4 that drives support plate 2 and freeze-drying plate layer 3 liftings, and the lifting actuator 4 in the present embodiment is oil cylinder.During work, be the bottle of the state of partly jumping a queue after completing 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 carried out tamponade, are pressed into the plug on bottle in bottleneck fully; 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, is communicated with by the through hole 9 of being located at 1 bottom, freeze-drying chamber between freeze-drying chamber 1 and cold-trap chamber 5; As shown in Figure 2, when dropping to 1 bottom, freeze-drying chamber when support plate 2 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 whole chamber, dividing plate 6 lateral arrangement are so that freeze-drying chamber 1 is up and down with cold-trap chamber 5 arranges, 9 of through holes are opened on dividing plate 6.When coil pipe 8 is defrosted, need to be with freeze-drying chamber 1 and cold-trap chamber 5 isolation, 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 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 provided driving power when both being used in tamponade, the valve that can be used as again freeze-drying chamber 1 and cold-trap chamber 5 break-makes 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 with dividing plate 6 sealing ring 10 that coordinates, and 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, all from then on discharge outlet 7 discharges of condensed water of freeze-drying chamber 1 and cold-trap chamber 5 generations.
Be only below the preferred embodiment of the present invention, protection scope of the present invention also not only is confined to above-described embodiment, and all technical schemes that belongs under thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art, the some improvements and modifications not breaking away under principle of the invention prerequisite should be considered as protection scope of the present invention.
