Description
Technical field
The utility model relates to drying device field, specifically low-temperature freeze-drying machine.
Background technology
Drying equipment is also known as drier and drying machine.For carrying out the equipment of drying process, by heating, the hygroscopic water in material (referring generally to moisture or other volatile liquid components) being vaporized and overflowing, to obtain the solid material of regulation water capacity.Dry object is the needs in order to material uses or processes further.As the drying of timber before making wooden model, woodenware can prevent product deformation, the drying of ceramic batch before calcining two drying equipment can prevent finished product from chapping.Dried material is also convenient to transport and storage in addition, if the grain drying that will gather in the crops is below certain moisture content, with anti-mildew.Because natural drying far can not meet the needs of production development, various mechanization drier is applied more and more widely.
Meanwhile, along with the development of productivity, the drying equipment of various different principle arises at the historic moment.The fixed-bed type drying machine of intermittently operated that what modern age, drying machine was brought into use is.In the middle of the 19th century, the use of Tunnel drier, indicates that drying machine is by the development of intermittently operated to continued operation direction.Revolving drum drier then achieves the stirring of granule materials preferably, and drying capacity and intensity are improved.Some industries have then developed the continued operation drying machine adapting to the industry and require respectively, as the roller drier of weaving, paper industry.In addition, in compressed air, the amount of steam is determined by compressed-air actuated temperature: when keeping compressed air pressure substantially constant, reduce compressed-air actuated temperature and can reduce water vapour content in compressed air, and unnecessary steam can condense into liquid.Freeze drier utilizes this principle to adopt Refrigeration Technique dried compressed air.Freeze drier system is made up of refrigeration system, vacuum system, heating system, electrical instrumentation control system.Freeze drier critical piece is drying box, condenser, freezing unit, vavuum pump, heating/cooling device etc.
At present, the vacuum freeze drier drying box of domestic production generally can reach the temperature of-50 DEG C ~-60 DEG C, and water vessel generally can reach-70 DEG C ~-80 DEG C temperature, and above temperature generally can meet the freeze-drying demand of most of goods.The freeze drying equipment required for there being lower temperature, collect the freeze drying equipment of the low-temperature solvents such as alcohol as needed, then prevailing price is high.
Summary of the invention
The utility model just for above technical problem, provide a kind of applied widely, structure simple, the low-temperature freeze-drying machine of the cheap low-temperature solvent collected.
The utility model realizes mainly through following technical scheme.
Low-temperature freeze-drying machine, comprise knockout, refrigeration system, front low temperature valve, low-temperature solvent collector, rear low temperature valve, low-temperature solvent flow export, drying system, negative pressure system, it is characterized in that drying system delivery port is connected in knockout, the refrigeration piping of refrigeration system is covered with in knockout, knockout carries out temperature control by refrigeration system, knockout side is connected with negative pressure system, front low temperature valve is provided with below knockout, knockout is connected with low-temperature solvent collector by front low temperature valve, low-temperature solvent collector lower end is connected with low-temperature solvent flow export by rear low temperature valve, and connect corresponding low-temperature solvent reservoir vessel by low-temperature solvent flow export.Refrigeration system selects multistage cascade refrigeration mode.Refrigeration system is multistage adjustable.Knockout lower inside forward low temperature valve place tilts.
The drying that the utility model carries out in various degree by multistage adjustable refrigeration system to the wet gas that drying system produces.When being adjusted to uniform temperature, by repeatedly operating several times, most corresponding low-temperature solvent can be collected.
The utility model structure is simple, esy to use, safe and reliable.
Accompanying drawing explanation

1-knockout, 2-refrigeration system, 3-front low temperature valve, 4-low-temperature solvent collector, 5-rear low temperature valve, 6-low-temperature solvent flow export, 7-drying system, 8-negative pressure system.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Low-temperature freeze-drying machine, comprise knockout 1, refrigeration system 2, front low temperature valve 3, low-temperature solvent collector 4, rear low temperature valve 5, low-temperature solvent flow export 6, drying system 7, negative pressure system 8, it is characterized in that drying system 7 delivery port is connected in knockout 1, the refrigeration piping of refrigeration system 2 is covered with in knockout 1, knockout 1 carries out temperature control by refrigeration system 2, knockout 1 side is connected with negative pressure system 8, front low temperature valve 3 is provided with below knockout 1, knockout 1 is connected with low-temperature solvent collector 4 by front low temperature valve 3, low-temperature solvent collector 4 lower end is connected with low-temperature solvent flow export 6 by rear low temperature valve 5, and connect corresponding low-temperature solvent reservoir vessel by low-temperature solvent flow export 6.Refrigeration system 2 selects multistage cascade refrigeration mode.Refrigeration system 2 is multistage adjustable.Knockout 1 lower inside forward low temperature valve 3 place tilts.
The utility model carries out drying in various degree by the wet gas that multistage adjustable refrigeration system 2 pairs of drying systems 7 produce.When being adjusted to uniform temperature, by repeatedly operating several times, most corresponding low-temperature solvent can be collected.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
