Abstract
The utility model provides a be applied to return air flow straightener in sterilization tunnel, including the frame, the frame includes plane framework and inclined plane frame, is equipped with the mesh board of angularly adjustable on the inclined plane frame, and the mesh board covers on the inclined plane of inclined plane frame. The utility model has the advantages that: can succeed to sterilization hot -blast flow equalizing in the box, guarantee the homogeneity of distribution of temperature on oven width direction to increase the inside wind pressure of heating section, make the tunnel oven accord with the GMP requirement more, and can prolong high efficiency filter's life, reduce the running cost.
Description
Technical field
This utility model relates to a kind of current equalizer, is mainly used in tunnel oven, regulates airflow homogeneity below guipure in bringing-up section, increases bringing-up section air pressure simultaneously.
Background technology
The uniform property of heat is that it requires that in sterilizing installation, each point all arrives predetermined sterilising temp about sterilizing important indicator in GMP.Sterilizing installation heat distribution is uneven is that it cannot by the major reason of checking, and in the sterilizing installation that heat distribution is uneven, the dry heat sterilization heat effect that partial containers obtains through sterilizing section reduces, thus does not reach depyrogenation effect.For this reason, the heat distribution of sterilizing installation is subject to common concern.
For hot air type tunnel sterilization baking oven, the uniform property of heat weighs the important indicator (hot uniform property refers to the temperature difference on baking oven width on same cross section between maximum temperature and minimum temperature) of performance, 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 hi-temp hi-effective filter, clean hot air carries out heat sterilization to medicine bottle, and air both comes back to heating element heater by the return air channel of side or bilateral and heats after medicine bottle.This special construction of circulated air, the medicine bottle causing distance return air channel near is due to hot blast abundance, and its sterilization effect is better than the medicine bottle away from return air channel.
Meanwhile, the position laying dust that the inhomogeneities of this air quantity also causes filter ventilation large is too concentrated, shortens the service life of hi-temp hi-effective filter, adds the operating cost of baking oven.
New edition GMP regulation bringing-up section pressure must be greater than other two sections.For ensureing that bringing-up section heating power is unaffected and avoid being secondary polluted.The air of the now necessary oriented both sides overflow of equipment, so equipment needs to mend wind to bringing-up section.How to produce negative pressure and carry out air draught, new requirement is created to equipment.
Summary of the invention
The technical problems to be solved in the utility model is: ensure that oven temperature is evenly distributed and protects high efficiency particulate air filter, and effectively can improve high temperature section benefit wind, thus realizes air pressure lifting in medicine bottle place above guipure.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided a kind of return air current equalizer being applied to sterilization tunnel, comprise frame, frame comprises plane framework and inclined-plane framework, inclined-plane framework is provided with the mesh plate of adjustable angle, and mesh plate covers on the inclined-plane of inclined-plane framework.
Preferably, one end of described mesh plate and described inclined-plane frame articulation, the other end is connected with described inclined-plane framework by angle adjusting mechanism.
Preferably, described angle adjusting mechanism comprises the otic placode being positioned at described mesh plate at least side, otic placode has angle adjustment holes, described mesh plate and described inclined-plane framework is locked after locking nut penetrates angle adjustment holes.
The utility model has the advantages that: successfully can carry out current-sharing to sterilizing casing interior-heat wind, ensure the uniformity of Temperature Distribution on baking oven width, and increase the inner blast of bringing-up section, tunnel oven is made more to meet GMP requirement, and the service life of high efficiency particulate air filter can be extended, reduce operating cost.
Utility model works is reliable and easily manufactured, can also bring good economic benefit.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart;
Fig. 2 is this utility model schematic diagram;
Fig. 3 is that this utility model implements schematic diagram.
Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The technical solution of the utility model is to provide a kind of novel current equalizer, it is characterized in that:
As depicted in figs. 1 and 2, a kind of return air current equalizer being applied to sterilization tunnel that this utility model provides comprises support 1, mesh plate 2, locking nut 3, support 1 is equipped with the mesh plate 2 of adjustable angle, and is fixed by clamp nut 3.Mesh plate 2 adjustable-angle, to realize bottom mesh plate 2 gap change, realizes from the local air inlet adjustment away from return air channel, and is undertaken fastening by locking nut 3.
As shown in Figure 3, clean air by heating element heats to technological requirement temperature, its principle is that clean air and heating element heater carry out heat exchange, by blower fan, hot-air is sucked fan housing from a-quadrant again, after hi-temp hi-effective filter, clean hot air carries out heat sterilization to medicine bottle, and clean air enters B region by C region after medicine bottle, both comes back to heating element heater by the return air channel of side and heats.
This utility model is arranged between region B and region C, and the angle of Controling network orifice plate 2 can gap size bottom Controling network orifice plate, thus the distribution of adjustment medicine bottle cross section resistance.This utility model regulates mesh plate 2 angle according to test wind speed and airflow homogeneity, if large from the local wind speed close to return air channel, then tune up angle, and then the resistance reduced away from return air channel place, corresponding increase is away from the air quantity at return air channel place, the air quantity caused the existence due to return air channel is uneven to be compensated, and makes the air quantity of baking oven width even.
Because equipment is between region B and region C, add circulating resistance to passage, air-flow can be forced to enter from region D (and extraneous), thus the equipment that reaches increases the effect of mending wind, thus increase bringing-up section internal pressure.
This utility model is generally arranged in tunnel oven sterilizing section return air channel, and according to the change flexible angle adjustment of wind speed in machine debug process, can remain the hot blast air quantity uniformity of baking oven width.
