Abstract
The invention relates to a gas guide device used for a freeze dryer condenser which comprises a cylinder body and a plurality of three-stage heat exchange plates that are arranged in the cylinder body in a fan shape, wherein the cylinder body is connected with an external vacuum pump through a pipeline, the pipeline is provided with a vacuum aspirating hole, the gas guide device comprises a guide plate and a plurality of bent fixing plates connected to one side surface of the guide plate at intervals, a clamping structure is formed to be clamped and fixed on the three-stage heat exchange plate close to the vacuum aspirating hole, the guide plate supports against one side surface of the three-stage heat exchange plat, and the top edge of the guide plate supports against the inner wall of the cylinder body. The invention effectively ensures that airflow is uniformly distributed on the periphery of the three-stage heat exchange plates so as to play a role of uniformly guiding to make the surfaces of the three-stage heat exchange plates frost uniformly, thereby avoiding reducing the condensing capacity of the condenser.
Description
Technical field
The present invention relates to a kind of pharmaceutical machine, relate in particular to a kind of air flow guiding device that is used for the freeze dryer condenser.
Background technology
Freeze-drying prods in the freeze dryer casing can produce a large amount of steam at a sublimation stage, these steam can be by the suction of vavuum pump and the pressure differential of front and back case, flow to the condenser the inside, and form frost attached to the triple heat exchanger plates surface in the condenser.Yet, vacuum pumping opening one side at condenser, may assemble a large amount of steam, these steam become thick frost in the triple heat exchanger plate surface condensations near bleeding point, and may have only a spot of frost from the more remote triple heat exchanger plates surface of bleeding point or do not have, thereby cause the condenser frosting inhomogeneous, this will greatly reduce the coagulability of condenser.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the present invention aims to provide a kind of air flow guiding device that is used for the freeze dryer condenser, to avoid reducing the coagulability of condenser.
A kind of air flow guiding device that is used for the freeze dryer condenser of the present invention, described condenser comprises that a cylindrical shell and several are the triple heat exchanger plates of fan-shaped array in this cylindrical shell, and this cylindrical shell is connected with external vacuum pump by pipeline one, this pipeline is provided with a vacuum pumping opening, described air flow guiding device comprises that a deflector and several are connected the bending fixed head of this deflector one side at interval, and constitute one and clamp structure, with clamping near on triple heat exchanger plates of described vacuum pumping opening, described deflector is resisted against on the side of these triple heat exchanger plates, and the top margin of this deflector is resisted against on the inwall of described cylindrical shell.
At the above-mentioned air flow guiding device that is used for the freeze dryer condenser, the described cross section that clamps structure is h shape, and this clamps the thickness coupling of width and described triple heat exchanger plates of structural openings end.
At the above-mentioned air flow guiding device that is used for the freeze dryer condenser, the length of described deflector is identical with the length of described triple heat exchanger plates.
At the above-mentioned air flow guiding device that is used for the freeze dryer condenser, described bending fixed head is evenly distributed on the side of described deflector.
Owing to adopted above-mentioned technical solution, the present invention is by connecting into h shape with deflector and bending fixed head, and clamping is on the top of triple heat exchanger plates, thereby effectively guaranteed air-flow be evenly distributed in all triple heat exchanger plates around, played even guide functions, make triple heat exchanger plate surface frostings even, avoided reducing the coagulability of condenser; The present invention also has advantages such as simple in structure, easy for installation, cheap except the water conservancy diversion effect is very remarkable.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
See also Fig. 1 to Fig. 3, the present invention, a kind of air flow guiding device that is used for the freeze dryer condenser, condenser comprises that a cylindrical shell 4 and several are the triple heat exchanger plates 5 of fan-shaped array in this cylindrical shell 4, and this cylindrical shell 4 is connected with external vacuum pump 6 by pipeline one, and this pipeline is provided with a vacuum pumping opening 41.Air flow guiding device comprises that a deflector 1 and several are evenly distributed on the bending fixed head 2 on the side of deflector 1, and constitute the structure that clamps that a cross section is h shape, with clamping near on triple heat exchanger plates 5 of vacuum pumping opening 41, this clamps the thickness coupling of width and triple heat exchanger plate 5 of structural openings end, deflector 1 is resisted against on the side of these triple heat exchanger plates 5, and the top margin of this deflector 5 is resisted against on the inwall of cylindrical shell 4, is inclination in 1: 50 with condenser cylindrical shell 4; The length of deflector 1 is identical with the length of triple heat exchanger plates 5.
What the deflector 1 among the present invention adopted is the thick corrosion resistant plate of 2mm, each fixed head 2 is fixing by screw and the deflector 1 of two M5, the whole formation of guiding device h shape is fixed, directly clamping is on the top of triple heat exchanger plates 5, guarantee air-flow be evenly distributed in all heat exchanger plates around, play even guide functions.
In sum, the present invention is water conservancy diversion steam effectively, makes triple heat exchanger plate frostings even, avoids reducing the coagulability of condenser, and have simple and easy, fixing simple, the low cost and other advantages of device.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
