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 double bottom 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 and temperature probe 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 bottom, traditional xeothermic cabinet product chamber is a single layer structure; The temperature that bottom temp is popped one's head in and the middle part temperature probe is measured is on the low side bigger; The temperature that is cavity bottom and other part is much lower; Cause the temperature distributing disproportionation of product cavity space even, satisfied not by the instructions for use of sterilising prods sterilization.
Referring to Fig. 2, product chamber 8 and the upper reaches thereof 10 and the blast pipe 2 in downstream 4 and the different opening of exhaust duct 11 that are positioned on the frame 4 guarantee that there is certain minute-pressure power in the product chamber for 8 li; Under the effect of circulating fan 1, air circulation begins in the product chamber 8, is that the upper reaches of air high efficiency particulate air filter 9 get into the principal section filter element filtering through it from the upper reaches, product chamber 10, and downstream, product chamber 4 return air are participated in circulation.The measured temperature difference of bottom temp probe 5 and middle part temperature probe 3 is bigger, and promptly the temperature difference of cavity bottom and other part is a lot, causes the Temperature Distribution of product cavity space very inhomogeneous, and this does not meet the requirement of technology.
[summary of the invention]
In order to overcome the existing dry heat sterilization cabinet product chamber very uneven deficiency of Temperature Distribution at high temperature, utility model of the present invention provides a kind of double bottom structure that has, and makes the better dry heat sterilization cabinet of product chamber 8 temperature distribution evenness.
For realizing above-mentioned purpose; Design a kind of dry heat sterilization cabinet that has double bottom structure, comprising: air intake passage, air-out passage in the cabinet, cabinet, be arranged on circulating fan, air high efficiency particulate air filter on the cabinet, air intake passage communicates with the circulating fan exhaust outlet; The air-out passage is connected with the circulating fan air inlet; Air intake passage and air-out interchannel separate with dividing plate, and product intracavity middle part and bottom are provided with temperature probe, it is characterized in that between at the bottom of product chamber base plate and the cabinet, being provided with an interlayer; Said interlayer communicates with air-out passage, the outlet of air high efficiency particulate air filter, and described air high efficiency particulate air filter is located at product chamber and inlet air interchannel.
Bottom, described product chamber is connected at a distance from empty through spacer block with bottom of cabinet bulk.
High temperature circulation wind is by the upper reaches, product chamber 10, through getting into product chamber 8 after the filtration of air high efficiency particulate air filter 9, the product in product chamber 8 remained on a certain design temperature certain hour inner drying, sterilization or removes thermal source, and downstream, product chamber 4 return air are participated in circulation.The below that it is characterized in that the bottom, product chamber 7 in product chamber 8 is provided with product chamber double bottom 13; Formed unique bottom, product chamber interlayer 12 like this between bottom 7, product chamber and the product chamber double bottom 13; A part is through the clean wind of the filtering high temperature of high efficiency particulate air filter bottom, interlayer 12 insulating product chambeies 7 bottom the product chamber; Make 8 bottom temps pop one's head in 5 measured temperatures and middle part temperature probe 3 measured temperatures in product chamber approaching, promptly the Temperature Distribution under 8 high temperature of entire product chamber is very even.
This utility model compared with prior art; Novel structure, practicality; Unique product chamber double bottom structure, not only made the product chamber do not have " dead angle " avoided any maybe be remaining pollution but also play insulation effect and make the product chamber at high temperature Temperature Distribution is very even, dependable performance, stable.
