Abstract
The utility model provides a sterilization filter's anti -corrosion structure, includes and is provided with the filter element in the column shell by the column shell, the give vent to anger end and jar body intercommunication of column shell, and inlet end and atmosphere intercommunication, the end of giving vent to anger passes through first check valve intercommunication with a jar body, jar part that the body is connected with first check valve still is connected with and is used for carminative second check valve. Owing to in having the unable sterilization filter of inflow of aggressive fume's mist, consequently, effectively avoided the filter element in the sterilization filter to be corroded the oxidation and damage, guaranteed that sterilization filter's degerming performance is not impaired, the messenger gets into jar internal air and is in the germ -free condition all the time, guarantees the quality of the internal product of jar, has prolonged sterilization filter's life, has reduced sterilization filter's replacement cost to manufacturing cost has been reduced.
Description
Technical field
This utility model relates to fill field, particularly to the anti-corrosion structure of the sterilizing filter being passed through in filling apparatus on the hermetic container of corrosive gas.
Background technology
nullAt present，In fill field，In order to prevent outside air from bringing antibacterial into pollute the product in hermetic container in its filling apparatus，The outside air to entering in hermetic container is then needed to carry out bacteria removing，As shown in Figure 1，Its bactericidal device includes the sterilizing filter being connected on tank body 101，Described sterilizing filter includes that shell 102 strengthened by post，Filter element 103 it is provided with in cylindrical shell 102，Cylindrical shell 102 one end connects with tank body 101，The other end and atmosphere，Outside air is entered in shell 102 by the inlet end of cylindrical shell 102，Through filter element 103 carry out degerming after，Entered in tank body 101 by the connection end of cylindrical shell 102 with tank body 101，By filter element 103, the outside air entered is carried out bacteria removing，To ensure that the gas contacted with product is as filtrated air，Owing to sterilizing filter and tank body 101 junction do not have direction to limit，Therefore，It is in the mixed gas in tank body 101 to be entered in sterilizing filter by the junction reflux of sterilizing filter Yu tank body 101 when being exhausted，Owing to this mixed gas is contained within the corrosive gas such as ozone，Therefore，Filter element in sterilizing filter can be corroded by these corrosive gas，In use for some time，Filter element can oxidized destruction，Thus degerming requirement cannot be met，Thus the quality of product cannot be ensured，And sterilizing filter is often changed due to needs，Also production cost is greatly improved.
Utility model content
This utility model aims to provide the anti-corrosion structure that a kind of filter element being prevented effectively from sterilizing filter is corroded, and to extend the service life of sterilizing filter, improves the quality of product, reduces production cost.
The anti-corrosion structure of a kind of sterilizing filter described in the utility model, including cylindrical shell, filter element it is provided with in cylindrical shell, the outlet side of cylindrical shell connects with tank body, inlet end and atmosphere, described outlet side is connected by the first check-valves with tank body, and the part that described tank body and the first check-valves connect is also associated with the second check-valves for aerofluxus.
nullThe anti-corrosion structure of a kind of sterilizing filter described in the utility model，Second check-valves is connected with exhaust gas processing device，Owing to the first check-valves and the second check-valves are all check valve，During air inlet，Air is flowed in tank body through the first check-valves by sterilizing filter，When aerofluxus，Mixed gas in tank body is when reverse direction flow sterilizing filter，Owing to the first check-valves is check valve，Its flow direction is to be flowed to tank body by sterilizing filter，Therefore，Mixed gas cannot flow in sterilizing filter，The flow direction of the second check-valves is then to be flowed to exhaust gas processing device by tank body，Therefore，Mixed gas is then flowed in exhaust gas processing device by the second check-valves，Owing to cannot flow in sterilizing filter with the mixed gas of corrosive gas，Therefore，Effectively prevent the filter element in sterilizing filter be corroded oxidation and damage，Ensure that the degerming performance of sterilizing filter is the most impaired，The air in entrance tank body is made to be in aseptic condition all the time，The quality of product in guarantee tank body，Extend the service life of sterilizing filter，Reduce the replacement cost of sterilizing filter，Thus reduce production cost.

Detailed description of the invention
A kind of anti-corrosion structure of sterilizing filter, as shown in Figures 2 and 3, including cylindrical shell 1, filter element 2 it is provided with in cylindrical shell 1, the outlet side of cylindrical shell 1 connects with tank body 3, inlet end and atmosphere, described outlet side is connected by the first check-valves 4 with tank body 3, and the part that described tank body 3 is connected with the first check-valves 4 is also associated with the second check-valves 5 for aerofluxus.
Described filter element 2 is high molecular filter element.
Claims (2)
1. the anti-corrosion structure of a sterilizing filter, including cylindrical shell (1), filter element (2) it is provided with in cylindrical shell (1), the outlet side of cylindrical shell (1) connects with tank body (3), inlet end and atmosphere, it is characterized in that: described outlet side is connected by the first check-valves (4) with tank body (3), and the part that described tank body (3) is connected with the first check-valves (4) is also associated with the second check-valves (5) for aerofluxus.
