Abstract
The invention discloses a high efficiency filter sealing structure used for a tunnel type sterilization drying oven, which is characterized by comprising a tunnel drying oven body and an air duct, wherein a wind cover is arranged on the upper side of the tunnel drying oven body; a horn-shaped mouth of the wind cover is arranged on the lower end; a high efficiency filter is arranged between the wind cover and the tunnel drying oven body; the upper end of the wind cover is connected with an air outlet of a fan through a fan volute; one end of the air duct is connected with the tunnel drying oven body; the other end of the air duct is connected with an exhaust inlet of the fan through the fan volute. By using the high efficiency filter sealing structure, the sealing effect between the high efficiency filter and the tunnel drying oven body is effectively ensured, the influence of visible foreign objects and insoluble particles on the tunnel drying oven is reduced, and the tunnel drying oven can more meet the GMP (Good Manufacturing Practice) requirement.
Description
Technical field
The present invention relates to a kind of high efficiency particulate air filter sealing means that is applied to tunnel oven, can effectively solve the sealing between high efficiency particulate air filter and tunnel oven under sealing problem, the particularly condition of high temperature between high efficiency particulate air filter and tunnel oven by the sealing mode.
Background technology
Hundred grades of laminar flows are after air is passed through high efficiency particulate air filter with certain wind speed, to form equal fluid layer, make pure air be vertical way flow, thereby have guaranteed to reach in the workspace cleanliness factor of technological requirement.Hundred grades of laminar flows have important effect in tunnel oven, can effectively reduce the impact on tunnel oven of visible foreign matters and particulate matter.High efficiency particulate air filter plays an important role in the process that forms hundred grades of laminar flows.For this reason, the sealing means between high efficiency particulate air filter and tunnel oven is subject to common concern, particularly the sealing between high temperature high efficiency particulate air filter and tunnel oven.
In old-fashioned tunnel oven, adopt sealing strip to seal between high efficiency particulate air filter and tunnel oven.But through after long operation, sealing strip may be aging and have particulate to come off, thereby reduce sealing effectiveness.Particularly the high temperature high efficiency particulate air filter can embrittlement produce leakage through long hot operation fluid sealant.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high efficiency particulate air filter sealing means that is applied to tunnel oven, to guarantee the sealing effectiveness between high efficiency particulate air filter and tunnel oven.
In order to solve the problems of the technologies described above, technical scheme of the present invention has been to provide a kind of hermetically-sealed construction of high efficiency particulate air filter for tunnel-type sterilizing oven, it is characterized in that, comprise tunnel oven casing and air channel, the upside of tunnel oven casing is provided with fan housing, the horn mouth of fan housing, in lower end, is provided with high efficiency particulate air filter between fan housing and tunnel oven casing, and the upper end of fan housing is connected with the air outlet of blower fan by volute of blower; One end in air channel is connected with the tunnel oven casing, and the other end is connected with the inlet scoop of blower fan by volute of blower.
Preferably, described air channel is provided with square opening towards a side of fan housing.
Air channel is connected with the tunnel oven welding box body, and fan housing is not connected by other bindiny mechanisms with high efficiency particulate air filter.
The present invention effectively guarantees the sealing effectiveness between high efficiency particulate air filter and tunnel oven, reduces visible foreign matters and particulate matter to the impact of tunnel oven, makes tunnel oven more meet the GMP requirement.

Embodiment
As shown in Figure 1-2, structural representation for a kind of hermetically-sealed construction of high efficiency particulate air filter for tunnel-type sterilizing oven provided by the invention, comprise tunnel oven casing 6 and air channel 1, the upside of tunnel oven casing 6 is provided with fan housing 4, the horn mouth of fan housing 4 is in lower end, be provided with high efficiency particulate air filter 5 between fan housing 4 and tunnel oven casing 6, the upper end of fan housing 4 is connected with the air outlet of blower fan 3 by volute of blower 2.One end in air channel 1 is connected with tunnel oven casing 6, and the other end is connected with the inlet scoop of blower fan 3 by volute of blower 2.Fan housing 4 is pressed in high efficiency particulate air filter 5 on tunnel oven casing 6, is welded to connect between air channel 1 and tunnel oven casing 6.1 opens a square opening 7 towards a side of fan housing 4 in air channel.
As shown in Figure 3, during blower fan 3 work, because 1 side, air channel has square opening 7, guarantee that fan housing 4 and tunnel oven casing 6 inside keep malleation with respect to outside, be to be zone of positive pressure in fan housing 4 and tunnel oven casing 6, be negative pressuren zone between air channel 1 and fan housing 4, guaranteed that visible foreign matters and particulate matter can not see through high efficiency particulate air filter 5 and enter in tunnel oven casing 6 (in figure, arrow is pressure directions).
