Description
[technical field]
This utility model relates to dry heat sterilization cabinet and hot air oven technical fields such as pharmaceutical industry or medical industry, a kind of specifically dry heat sterilization cabinet that has two contacts wire or multi-ring linear sealing structure.
[background technology]
Dry heat sterilization cabinet is the widely used sterilizing-drying equipment of industry such as pharmacy medical treatment; Can be used for withstand higher temperatures and but should not penetrated or be prone to by damp and hot destructive article sterilization, simultaneously xeothermic also be material in the pharmaceuticals industry drying, remove one of method of thermal source, dry sterilization is meant that heater heats air; And utilize air to do medium; Heat evenly is delivered on the material, and takes away moisture content, reach the effect of xeothermic degerming.
At present, known dry heat sterilization cabinet mainly is made up of product chamber, air inlet system, exhaust system, circulating fan, intracavity air high efficiency particulate air filter, door and door sealing etc.Circulated air is under the effect of circulating fan, and the filtration of the principal section filter element through intracavity air high efficiency particulate air filter continues circulation, filters self-cleaning the product cavity air, and is progressively clean to hundred grades of requirements of cleanliness factor.In dry, sterilization or remove the thermal source stage; Temperature reaches as high as 300 ℃; High temperature circulation wind is by the upper reaches, product chamber; Through getting into the product chamber after the filtration of air high efficiency particulate air filter, the product in product chamber is remained on a certain design temperature certain hour inner drying, sterilization or removes thermal source, downstream, product chamber return air is participated in circulation.But traditional xeothermic cabinet door weather strip contacts for the wall scroll loop wire with the contact wire of door; Cause the partial points of clean (or the outdoors) air of product intracavity high temperature to reveal; The air of chamber " way flow " distributes; Might become part " turbulent flow " and distribute, cause the even cleanliness factor of temperature distributing disproportionation of product cavity space defective, satisfy not by the instructions for use of sterilising prods sterilization.
Referring to Fig. 2, be positioned at the blast pipe (202) of product chamber (207) and upstream and downstream (212) (204) thereof on the frame (205) and the different opening of exhaust duct (213) and guarantee that there is certain minute-pressure power lining, product chamber (207); Under the effect of circulating fan (201), the interior air circulation in product chamber (207) begins, and is that the upper reaches of air high efficiency particulate air filter (211) get into the principal section filter element filtering through it from the upper reaches, product chamber (212), and downstream, product chamber (204) return air is participated in circulation.Door weather strip (209) is fixed on the doorframe (210); Sealing contact wire between door (208) and the door weather strip (209) is single link line (203) sealing, and it is not tight that monocycle contact wire (203) is gone up some dot encapsulations, causes the regional area of the interior high temperature pure air in product chamber (207) to reveal; The air of chamber " way flow " distribution equilibrium is destroyed; Might become part " turbulent flow " and distribute, cause the even cleanliness factor of temperature distributing disproportionation of product cavity space defective, this does not meet the requirement of technology.
[summary of the invention]
In order to overcome existing dry heat sterilization cabinet product the chamber very inhomogeneous and underproof deficiency of cleanliness factor of Temperature Distribution at high temperature; This utility model provides a kind of two contact seal loop wire structures that have, and makes product cavity temperature distributing homogeneity better reach the better dry heat sterilization cabinet of cleanliness factor.
For realizing above-mentioned purpose; Design a kind of dry heat sterilization cabinet that has two contact wire hermetically-sealed constructions; Comprise: air intake passage, air-out passage in the cabinet, cabinet, be arranged on circulating fan (1), air filter (12) on the cabinet; Air intake passage communicates with the circulating fan exhaust outlet, and the air-out passage is connected with the circulating fan air inlet, and door weather strip (10) is fixed on the doorframe (11); Door weather strip makes door (9) and product chamber (8) sealing, it is characterized in that being provided with sealing strip contact wire outer shroud (3) and sealing strip contact wire internal ring (4) between door and the door weather strip.
Can be provided with multi-ring sealing strip contact wire loop between said sealing strip contact wire outer shroud (3) and the sealing strip contact wire internal ring (4).
High temperature circulation wind is by the upper reaches, product chamber (13); Through getting into product chamber (8) after the filtration of air high efficiency particulate air filter (12); The product of product chamber (8) is remained on a certain design temperature certain hour inner drying, sterilization or removes thermal source, and downstream, product chamber (4) return air is participated in circulation.Sealing contact wire between door (9) and the door weather strip (10) is double loop wire (3), (5) or multi-ring linear sealing; Reduced poorly sealed probability on the monocycle contact wire; The interior high temperature pure air in product chamber (8) " way flow " is distributed; It is qualified to be that Temperature Distribution under the high temperature of entire product chamber (8) very evenly reaches cleanliness factor, meets the requirement of technology.
This utility model compared with prior art; Novel structure, practicality; Unique door double loop wire or multi-ring linear sealing structure had both made the product chamber can not reveal, and had avoided any pollution that maybe be remaining; Play again make the product chamber at high temperature Temperature Distribution very evenly to reach cleanliness factor qualified, dependable performance, stable.
