Abstract
The utility model relates to a flow equalizing device for a tunnel type sterilization oven. The flow equalizing device for the tunnel type sterilization oven is characterized by comprising a fan cover, a flow equalizing mechanism is arranged in the fan cover, and a flow equalizing air channel for guaranteeing that hot air quantity in the width direction of the tunnel type sterilization oven is uniform is formed by the flow equalizing mechanism. The flow equalizing device for the tunnel type sterilization oven has the advantages of being capable of equalizing flow of hot air in a sterilization oven body smoothly, guaranteeing distribution uniformity of temperature in the oven width direction, enabling the tunnel oven to meet requirements of good manufacturing practice (GMP), being capable of prolonging service life of an efficient filter, and reducing operation cost.
Description
Technical field
This utility model relates to a kind of current equalizer that is applied in the tunnel oven, by this current equalizer the hot blast uniformity that enters high efficiency particulate air filter in the bringing-up section is regulated.
Background technology
The uniform property of heat is an important indicator about sterilizing among the GMP, and it requires, and each point all arrives predetermined sterilising temp in the sterilizing installation.The sterilizing installation heat distribution is inhomogeneous to be that it can't be by the major reason of checking, and in the inhomogeneous sterilizing installation of heat distribution, the part container reduces through the dry heat sterilization heat effect that the sterilization section obtains, thereby does not reach the depyrogenation effect.For this reason, the heat distribution of sterilizing installation has been subject to common concern.
For hot air type tunnel sterilization baking oven, the uniform property of heat is to weigh the important indicator of performance (hot uniform property refers on the baking oven width temperature difference between the maximum temperature and minimum temperature on the same cross section), its principle is that clean air and heating element heater carry out heat exchange, by blower fan hot-air is blown into fan housing again, after passing the high temperature high efficiency particulate air filter, clean hot air is carried out heat sterilization to medicine bottle, and air heats through both coming back to the heating element heater place by the return air channel of a side or bilateral behind the medicine bottle.This special construction of circulated air causes apart from the near medicine bottle of return air channel because hot blast is sufficient, and its sterilization effect is better than the medicine bottle away from return air channel.
Simultaneously, the inhomogeneities of this air quantity also causes the large position laying dust of filter ventilation too concentrated, has shortened the service life of high temperature high efficiency particulate air filter, has increased the operating cost of baking oven.
Summary of the invention
The purpose of this utility model provides a kind of current equalizer, to guarantee uniformity of temperature profile and protection high efficiency particulate air filter in the baking oven.
In order to achieve the above object, the technical solution of the utility model has provided a kind of current equalizer for tunnel-type sterilizing oven, it is characterized in that: comprise fan housing, in fan housing, be provided with current-sharing mechanism, formed the uniform current-sharing of the hot blast air quantity air channel that guarantees the tunnel-type sterilizing oven width by current-sharing mechanism.
Preferably, described current-sharing mechanism is the adjustable accent air blade of angle that is arranged in the described fan housing, transfers between the air blades by adjacent two to form described current-sharing air channel not of uniform size.
Preferably, the two ends of described accent air blade are by being connected and fixed between locking nut and the described fan housing.
Preferably, the axial direction of described accent air blade is vertical with the width of tunnel-type sterilizing oven.
The utility model has the advantages that: can success sterilization casing interior-heat wind is carried out current-sharing, guarantee the uniformity of Temperature Distribution on the baking oven width, so that tunnel oven meets the GMP requirement more, and can prolong the service life of high efficiency particulate air filter, reduce operating cost.
Description of drawings
Fig. 1 is the upward view of a kind of current equalizer for tunnel-type sterilizing oven in the present embodiment;
Fig. 2 is a kind of schematic perspective view for tunnel-type sterilizing oven in the present embodiment;
Fig. 3 is a kind of scheme of installation for tunnel-type sterilizing oven in the present embodiment.
The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figures 1 and 2, the disclosed a kind of current equalizer for tunnel-type sterilizing oven of the present embodiment comprises fan housing 1, in fan housing 1, be arranged with the adjustable accent air blade 2 of many angles, by forming current-sharing air channel not of uniform size between adjacent two accent air blades 2, transfer the two ends of air blade 2 by being connected and fixed between locking nut 3 and the fan housing 1.
As shown in Figure 3, in use, a kind of current equalizer for tunnel-type sterilizing oven that this utility model is provided is placed on the top of the high efficiency particulate air filter 4 of tunnel-type sterilizing oven, also can utilize high efficiency particulate air filter 4 original fan housings that are positioned at the air inlet position to install and transfer air blade 2.
During work, clean air is heated to the technological requirement temperature by heating element heater, and then blower fan is sent into high efficiency particulate air filter 4 with hot blast by fan housing 1.Each transfers the angle of air blade 2 to transfer to respective angles can guarantee that the hot blast air quantity of tunnel-type sterilizing oven width is even.
This utility model provides and can adjust flexibly blade angle according to the variation of operating mode in the machine use procedure, remains the hot blast air quantity uniformity of baking oven width.
