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

[0001] The invention relates to a pharmaceutical machine, in particular to a gas guide device for a freeze dryer condenser. Background technique

[0002] The freeze-dried product in the freeze dryer box will generate a large amount of water vapor during the first sublimation stage. The water vapor will flow into the condenser through the suction of the vacuum pump and the pressure difference between the front and rear boxes, and adhere to the triple heat in the condenser. Frost formed by exchanging the surface of the plate. However, on the side of the vacuum suction port of the condenser, a large amount of steam may accumulate, and these steams condense into thick frost on the surface of the triple heat exchange plate near the suction port, while the surface of the triple heat exchange plate farther away from the suction port There may be only a small amount of frost or no frost, resulting in uneven frosting of the condenser, which will greatly reduce the co...

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] see Figure 1 to Figure 3 , the present invention, a gas guide device for the condenser of a lyophilizer, the condenser includes a cylinder 4 and several triple heat exchange plates 5 arranged in the cylinder 4 in a fan shape, and the cylinder 4 It is connected to the external vacuum pump 6 through pipeline one, and the pipeline is provided with a vacuum pumping port 41 . The gas deflector device includes a deflector 1 and a number of bent fixed plates 2 evenly distributed on one side of the deflector 1, and forms a clamping structure with an H-shaped cross section to be clamped in a position close to the vacuum. On the triple heat exchange plate 5 of the suction port 41, the width of the opening end of the clamping structure matches the thickness of the triple heat exchange plate 5, and the deflector 1 abuts against one side of the tr...
