Abstract
The utility model discloses a high-efficiency filter seal structure for a tunnel sterilization drying oven. The high-efficiency filter seal structure is characterized in that: the high-efficiency filter seal structure comprises a tunnel drying oven body and an air channel. The upper side of the tunnel drying oven body is provided with a fan cover, wherein a horn mouth of the fan cover is at the lower end. A high-efficiency filter is arranged between the fan cover and the tunnel drying oven body. The upper end of the fan cover is connected with an air outlet of a draught fan through a fan volute. One end of the air channel is connected with the tunnel drying oven body and the other end is connected with an air inlet of the draught fan through the fan volute. According to the high-efficiency filter seal structure for the tunnel sterilization drying oven, the sealing effect between the high-efficiency filter and the tunnel drying oven is effectively guaranteed, the influence of visible foreign matters and insoluble particles on the tunnel drying oven is reduced, and the tunnel drying oven is accorded with GMP requirements more.
Description
Technical field
The utility model relates to a kind of high efficiency particulate air filter sealing means that is applied to tunnel oven, by sealing mode, can effectively solve the sealing between high efficiency particulate air filter and tunnel oven under the sealing problem between high efficiency particulate air filter and tunnel oven, the particularly condition of high temperature.
Background technology
Hundred grades of laminar flows are that air is passed through, after high efficiency particulate air filter, to form equal fluid layer with certain wind speed, make pure air be vertical way flow, thereby have guaranteed to reach in workspace the 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.In the process that forms hundred grades of laminar flows, high efficiency particulate air filter plays an important role.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, between high efficiency particulate air filter and tunnel oven, adopt sealing strip to seal.But through after long operation, sealing strip may be aging and have particulate to come off, thereby reduce sealing effectiveness.Particularly 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 in the utility model 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, the technical solution of the utility model has been to provide a kind of high efficiency particulate air filter hermetically-sealed construction 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; The one end in air channel is connected with 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 tunnel oven welding box body, and fan housing is not connected by other bindiny mechanisms with high efficiency particulate air filter.
The utility model effectively guarantees the sealing effectiveness between high efficiency particulate air filter and tunnel oven, reduces visible foreign matters and the impact of particulate matter on tunnel oven, makes tunnel oven more meet GMP requirement.

Fig. 2 is the schematic perspective view in air channel;
Fig. 3 is a kind of principle schematic of the high efficiency particulate air filter hermetically-sealed construction for tunnel-type sterilizing oven.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1-2, the structural representation of a kind of high efficiency particulate air filter hermetically-sealed construction for tunnel-type sterilizing oven providing for the utility model, 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, between fan housing 4 and tunnel oven casing 6, be provided with high efficiency particulate air filter 5, the upper end of fan housing 4 is connected with the air outlet of blower fan 3 by volute of blower 2.The 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, between air channel 1 and tunnel oven casing 6, is welded to connect.In air channel, 1 opens a square opening 7 towards a side of fan housing 4.
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 fan housing 4 with tunnel oven casing 6 in be zone of positive pressure, between air channel 1 and fan housing 4, be negative pressuren zone, 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).
