The specific embodiment
Below with reference to Figure of description and specific embodiment the present invention is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, being applied to tunnel sterilizing and drying machine with the present invention is example, this baking oven comprises casing 2 and is installed in heater 1 in the casing 2, air-heater 3, fan housing 4, high temperature high efficiency particulate air filter 5, air-heater 3, fan housing 4, high temperature high efficiency particulate air filter 5 is from top to bottom arranged successively, the outlet air end of air-heater 3 is connected through the air inlet of fan housing 4 with high temperature high efficiency particulate air filter 5, high temperature high efficiency particulate air filter 5 be positioned at transmit guipure 8 upper bottle bodies 7 directly over, transmitting guipure 8 penetrates from casing 2 one sides, pass from opposite side, the bottle 7 that needs dry sterilization is sent into continuously sent casing 2.Fan housing 4 can loose hot-air and flow to high temperature high efficiency particulate air filter 5 tops and form malleation, forms high pressure chest 17 in the fan housing 4, and its force value with respect to the room is 100～400Pa.Nip territory 15 in forming between high temperature high efficiency particulate air filter 5 and the transmission guipure 8, its force value with respect to the room is 2～15Pa.(being the cabinets cavity of fan housing 4, high temperature high efficiency particulate air filter 5 peripheries) cabinets cavity forms negative pressure region 18 between the air intake of the outlet air end of heater 1 and air-heater 3, and its force value with respect to the room is-30～-60Pa.Negative pressure region 18 is with respect to high temperature high efficiency particulate air filter 5 belows and transmit the middle nip territory 15 that forms between the guipure 8, its negative pressure difference reached-47～-75Pa between.Casing 2 inner airs are endless form motions, the below of transmitting guipure 8 upper bottle bodies 7 is return air channel, to be directed at heater 1 air intake that is arranged in casing 2 one sides with the air-flow that bottle 7 carries out after the heat exchange, send air-heater 3 again again back to after finishing heating by heater 1.
High temperature high efficiency particulate air filter 5 comprises filter paper 14, ceramic seal glue 13 and stainless steel frame 12, because high temperature high efficiency particulate air filter 5 heating temperatures are than higher, can reach 300～400 ℃, and filter paper 14 is glass fiber material, they are different with stainless steel frame 12 materials, the coefficient of expansion is also different, and filter paper 14 is heated, and afterwards easy the appearance shrinks, amount of contraction is 2～5mm, filter paper 14 shrinks back ceramic seal glue 13 and cracking occurs, perhaps separate serious appearance filter paper 14 and ceramic seal glue 13 crackings with stainless steel frame 12.Easy like this causing in the bottle 7 that unclean air enters and sterilized produces secondary pollutions to bottle 7, has a strong impact on the qualification rate of medicine.
Among the present invention, the bottom supporting of high temperature high efficiency particulate air filter 5 also forms the flow-guiding channel 9 that is communicated with negative pressure region 18 on filter mounting 6, the unclean air that high temperature high efficiency particulate air filter 5 frames are revealed can be flowed to negative pressure region 18 through flow-guiding channel 9, again sucked back by air-heater 3 then, thus the cleanliness factor of assurance working chamber room air.
Referring to Fig. 4, in the present embodiment, filter mounting 6 comprises support plate 11 and the plural cradle 10 that is arranged on the support plate 11, support plate 11 is arranged in the bottom of high temperature high efficiency particulate air filter 5 in the form of a ring, the bottom supporting of high temperature high efficiency particulate air filter 5 is enclosed to form plural flow-guiding channel 9 between the bottom of cradle 10, support plate 11 and high temperature high efficiency particulate air filter 5 on cradle 10.Cradle 10 can be elongated cushion block, high temperature high efficiency particulate air filter 5 can have been filled up certain height, forms dead slot between the base of high temperature high efficiency particulate air filter 5 and the support plate 11 like this, becomes flow-guiding channel 9.
In the present embodiment, support plate 11 extends in the inner chamber of high temperature high efficiency particulate air filter 5, so just can surpass the zone of filter paper 14 and ceramic seal glue 13, and the unholiness air that ceramic seal Jiao13Chu could be revealed imports negative pressure region 18.An end that is positioned at high temperature high efficiency particulate air filter 5 inner chambers on the support plate 11 is provided with and is the deflector 16 that is in tilted layout, an end that is positioned at high temperature high efficiency particulate air filter 5 inner chambers on the deflector 16 is higher than an end that is positioned at high temperature high efficiency particulate air filter 5 outsides, namely be made as outward-dipping swash plate, can better air-flow be derived like this.
Below only be preferred embodiment of the present invention, protection scope of the present invention also not only is confined to above-described embodiment, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the principle of the invention prerequisite should be considered as protection scope of the present invention.
