Description

Shelf oil inlet structure of in-situ freeze dryer

Technical Field

The utility model relates to a shelf oil feed structure of normal position freeze dryer belongs to freeze dryer technical field.

Background

The freeze drying is to freeze the water-containing substance or solution in the sample at low temperature in advance, then change the vacuum environment to sublimate the crystallization water and then trap, thus obtaining the dried product, the equipment for completing the above process is the freeze dryer, the in-situ freeze dryer generally has a drying box and a cold trap, a shelf for placing the material to be dried is installed in the drying box, the shelf generally uses silicon oil as the heat transfer medium, the oil inlet of the shelf of the existing common type (also called standard type, namely fixed shelf) freeze dryer is connected by a corrugated pipe, as shown in figure 1, two corrugated pipes 4 are respectively arranged at the symmetrical two ends of the shelf 2 and are communicated with the flow channel in the shelf 2 by a right-angle pipe 3, thus, two corrugated pipes 4 are connected on each shelf 2, the other end of each corrugated pipe 4 is communicated with the silicon oil circulating device, and the two ends of the corrugated pipe 4 are fixed by welding, however, the bellows 4 has a thin wall and poor mechanical properties, so the welding process requirement is very high, and meanwhile, the welded material changes, and the bellows 4 with the thin wall and the joint thereof are easily broken and leaked by vibration impact, and particularly, in the shipping and transportation process of the freeze dryer, the accident that the bellows 4 is broken and leaked often occurs, so that the silicone oil is leaked in the drying box, and the freeze dryer cannot be used.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve lies in: the shelf oil inlet structure of the in-situ freeze dryer solves the problems that the freeze dryer is high in welding process requirement due to the connection of the corrugated pipes, and the corrugated pipes are easy to break due to impact, so that silicone oil leaks.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

a shelf oil feed structure for an in situ freeze dryer comprising:

the oil inlet pipe and the oil outlet pipe are respectively communicated with two ends of the flow channel, and the oil inlet pipe and the oil outlet pipe are of rigid straight pipe structures;

one of the main pipes is fixedly communicated with the oil inlet pipes, and the other main pipe is fixedly communicated with the oil outlet pipes;

and the fixed frame is multiple, and the shelves are sequentially arranged at intervals from top to bottom and are fixedly connected with the fixed frame.

As a preferable example, the flow channel is in an S-shaped arrangement, and the inlet and the outlet of the flow channel are positioned on the same side of the shelf.

The utility model has the advantages that: the utility model discloses a setting of straight tube, the straight tube setting is in the same one side of shelf to with house steward intercommunication, for the bellows junction of both sides, straight tube connected mode is simple, only need conventional welding process can, and the mechanical strength of straight tube is high, receives the vibration impact can not appear breaking the condition of leaking, has guaranteed the integrality in the freeze dryer transportation.

Drawings

FIG. 1 is a schematic view of a prior art oil feed configuration for a shelf;

FIG. 2 is a schematic structural view of the present invention;

fig. 3 is a schematic top view of fig. 1.

In the figure: the device comprises a fixed frame 1, a shelf 2, a right-angle pipe 3, a corrugated pipe 4, an oil inlet pipe 5, an oil outlet pipe 6, a header pipe 7 and a flow channel 8.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 2-3, a shelf oil feed structure of an in situ freeze dryer, comprising:

the shelf comprises a plurality of shelves 2, wherein a flow channel 8 is arranged inside each shelf 2, one side of each shelf 2 is fixedly connected with an oil inlet pipe 5 and an oil outlet pipe 6, the oil inlet pipe 5 and the oil outlet pipe 6 are respectively communicated with two ends of the flow channel 8, and the oil inlet pipe 5 and the oil outlet pipe 6 are both rigid straight pipe structures;

one header pipe 7 is fixedly communicated with the oil inlet pipes 5, and the other header pipe 7 is fixedly communicated with the oil outlet pipes 6;

fixed frame 1, a plurality of shelves 2 are from top to bottom in proper order the interval setting, and all with fixed frame 1 fixed connection.

Adopt above-mentioned scheme, a plurality of shelves 2 are installed in the drying cabinet through fixed frame 1, two house steward 7 all communicate with silicon oil circulating device, advance oil pipe 5 and go out oil pipe 6 and all set up same one side at shelf 2, and communicate with two house steward 7 respectively, advance oil pipe 5 and go out oil pipe 6 and all adopt the straight tube of rigidity, bellows 4 for both sides is connected, the straight tube connected mode is simple, and the pipe wall can suitably thicken, only need conventional welding process to connect, and the mechanical strength of straight tube is high, receive the vibration impact and can not appear the condition of rupture leakage, the integrality in the freeze dryer transportation has been guaranteed, what is worth mentioning is, advance oil pipe 5 and go out oil pipe 6 both ends also can be through setting up flange and shelf 2 and house steward 7 sealing connection, the installation mode has further been simplified, and can dismantle the change.

The flow channel 8 is arranged in an S shape, and the inlet and the outlet of the flow channel 8 are positioned on the same side of the shelf 2.

By adopting the scheme, the flow channel 8 uniformly penetrates through the shelf 2, the heating uniformity of the shelf 2 is ensured, and the traditional inlet and outlet arranged at two ends is changed into the inlet and outlet arranged at one end, so that the pipeline layout in the drying box is simplified.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
