Abstract
The utility model discloses a kind of cold-trap of freeze dryer, comprise trap body, coil pipe is provided with in described trap body, a deflector is also set in described trap body, described deflector is arranged on the gas access place of described trap body, and described deflector is made up of one piece of corrosion resistant plate, and described corrosion resistant plate decile is folded in half into the horn mouth shape of 30 degree, the broken line of described deflector is arranged near described gas access place, and described deflector and described coil pipe contour.The utility model can make water vapour be uniformly distributed in whole cold-trap space by deflector, and what improve coil pipe catches outlet capacity, prevents the generation of " ice blocks up " phenomenon.
Description
Technical field
The utility model relates to a kind of freeze dryer, particularly relates to a kind of cold-trap of freeze dryer.
Background technology
Current freeze dryer has been widely used in the fields such as pharmacy, food, biology, chemical industry.Cold-trap is the important component part of freeze drying equipment, its effect is that the water vapour that product in drying box distils out is freezed to be adsorbed on its metal surface, the water vapour distilling out from goods can condense on the inner surface of the stainless steel cylinder contacted with cold-trap coil pipe fully, thus ensures carrying out smoothly of freeze-drying process.Because cold-trap coil surface and frost layer surface exist the temperature difference, along with frost layer thickens, water vapour condenses too concentrated in cold-trap, easily causes " ice blocks up " and catches the problem of water poor-performing.
Utility model content
The purpose of this utility model is just the cold-trap providing a kind of freeze dryer in order to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A cold-trap for freeze dryer, comprises trap body, is provided with coil pipe in described trap body, also arranges a deflector in described trap body, and described deflector is arranged on the gas access place of described trap body.
In said structure, deflector moves backward for guiding air-flow, prevents the generation of " ice blocks up " phenomenon.
Particularly, described deflector is made up of one piece of corrosion resistant plate, and described corrosion resistant plate decile is folded in half into the horn mouth shape of 30 degree.
Particularly, the broken line of described deflector is arranged near described gas access place, and described deflector and described coil pipe contour.
The beneficial effects of the utility model are:
The utility model can make water vapour be uniformly distributed in whole cold-trap space by deflector, and what improve coil pipe catches outlet capacity, prevents the generation of " ice blocks up " phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cold-trap of a kind of freeze dryer of the utility model and its internal structure is shown.
In figure: 1-drier, 2-trap body, 3-vavuum pump, 4-coil pipe, 5-deflector.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the cold-trap of a kind of freeze dryer of the utility model, comprise trap body 2, be provided with coil pipe 4 in trap body 2, also arrange a deflector 5 in trap body 2, deflector 5 is arranged on the gas access place of trap body 2, deflector 5 is made up of one piece of corrosion resistant plate, corrosion resistant plate decile is folded in half into the horn mouth shape of 30 degree, and the broken line of deflector 5 is arranged near gas access place, and deflector 5 is contour with coil pipe 4.
Water vapour enters cold-trap by drier 1, on rear side of deflector 5, a pressure lower region is formed because water vapour enters cold-trap, thus make part water vapour after inflow cold-trap, move on rear side of deflector 5, add the motive force of vavuum pump 3, the temperature of the water vapour of deflector 5 posterior region can pass through the cooling of more polydisc pipe 4, makes it distribute at whole cold-trap space uniform, and that improves coil pipe 4 catches outlet capacity.
