Abstract
The invention provides a negative-pressure sealing frame used for a tunnel-type sterilization drying box. The negative-pressure sealing frame is characterized in that a negative-pressure sealing frame body is included, a pore plate is arranged in the middle of the negative-pressure sealing frame body, and washers are arranged on the outsides of the four sides of the negative-pressure sealing frame body. By means of the negative-pressure sealing frame, the filtering effect of an efficient filter can be effectively guaranteed, influences of visible foreign matter and insoluble particles on the tunnel-type drying box are reduced and accordingly the tunnel-type drying box meets the requirements of GMP better.
Description
Technical field
The present invention relates to a kind of negative-pressure sealing frame be applied in tunnel oven, effectively can solve high efficiency particulate air filter frame leakage problem by this negative-pressure sealing frame.
Background technology
In prior art, adopt sealing strip between high efficiency particulate air filter and base plate to seal.But for a long time after work, sealing strip can be aging and have particles from getting loose, pollutes below.Particularly hi-temp hi-effective filter fluid sealant after long hot operation embrittlement can produce leakage.
Summary of the invention
The object of this invention is to provide a kind of negative-pressure sealing frame for tunnel-type sterilizing oven, to ensure the sealing effectiveness between high efficiency particulate air filter and tunnel oven.
In order to achieve the above object, the invention provides a kind of negative-pressure sealing frame for tunnel-type sterilizing oven, it is characterized in that, comprise negative-pressure sealing frame body, the middle part of negative-pressure sealing frame body is orifice plate, and the portion outside four limits of negative-pressure sealing frame body is provided with pad.
Preferably, the corner of described negative-pressure sealing frame body is provided with limited block.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention effectively can ensure the filter effect of high efficiency particulate air filter, and reduction visible foreign matters and particulate matter, on the impact of tunnel oven, make tunnel oven more meet GMP requirement.
Accompanying drawing explanation
Fig. 1 installs sectional view for the negative-pressure sealing frame of tunnel-type sterilizing oven;
Fig. 2 is the negative-pressure sealing frame schematic perspective view for tunnel-type sterilizing oven;
Fig. 3 is the installation sectional view of negative-pressure sealing frame for tunnel-type sterilizing oven and filter;
Fig. 4 is the installation stereogram of negative-pressure sealing frame for tunnel-type sterilizing oven and filter.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 2, for the negative-pressure sealing frame schematic perspective view for tunnel-type sterilizing oven, the described negative-pressure sealing frame for tunnel-type sterilizing oven, comprise negative-pressure sealing frame body 6, the middle part of negative-pressure sealing frame body 6 is orifice plate, and the portion outside four limits of negative-pressure sealing frame body 6 is equipped with pad 8.Limited block 9 is equipped with in the corner of described negative-pressure sealing frame body 6.
As shown in Figure 3, in use, be placed on by filter 5 and be equipped with on the negative-pressure sealing frame body 6 of pad 8, just there is a gap in the frame of such filter 5 and negative-pressure sealing frame body 6, as shown in Figure 4, is limited the right position of filter by limited block 9.
As shown in Figure 1, during work, air circulates between air channel 1, spiral case 2, fan housing 4, filter 5, casing 7 through blower fan 3, and fan housing 4 side has hole, the outside formation negative pressure that connects with blower fan 3 inlet scoop of fan housing 4.Because have gap between filter 5 and negative-pressure sealing frame body 6, a small amount of air of bezel locations of casing 7 internal ramp 5 can be sucked out casing.Even if the bezel locations of filter 5 has leakage like this, also can ensure that leaking particulate can not enter below, but be sucked out casing 7 (in figure, arrow is pressure directions) in bezel locations.
Claims (2)
1. the negative-pressure sealing frame for tunnel-type sterilizing oven, it is characterized in that, comprise negative-pressure sealing frame body (6), the middle part of negative-pressure sealing frame body (6) is orifice plate, and the portion outside four limits of negative-pressure sealing frame body (6) is provided with pad (8).
2., as claimed in claim 1 for the negative-pressure sealing frame of tunnel-type sterilizing oven, it is characterized in that, the corner of described negative-pressure sealing frame body (6) is provided with limited block (9).
