Abstract
The utility model discloses a connecting structure for an inner oven body and an outer oven body of a tunnel type sterilization oven. The connecting structure for the inner oven body and the outer oven body of the tunnel type sterilization oven comprises the inner oven body and the outer oven body, and is characterized in that the inner oven body and the outer oven body are connected through expansion joints. The connecting structure for the inner oven body and the outer oven body of the tunnel type sterilization oven has the advantages that heat displacement can be successfully compensated, the structure is simple and practical, the connecting structure can be manufactured easily, reliability is high, and the like.
Description
Technical field
This utility model relates to a kind of syndeton for outer case in the tunnel-type sterilizing oven, belongs to the tunnel-type sterilizing oven field.
Background technology
The sterilization tunnel baking oven utilizes heated dry air to reach medicinal glass bottle is carried out microorganism killing and the former purpose of reducing phlegm and internal heat, and temperature is about sterilization and the former important indicator of reducing phlegm and internal heat among the GMP.It requires, and each point all reaches predetermined sterilising temp in the baking oven sterilization district; for being not less than 300 ℃; be protection operator safety and the impact that reduces clean room environment; sterilization tank external surface temperature should not be higher than 15 ℃ of room temperatures; this has just determined that the sterilization tunnel high-temperature region is the double-layer box body structure, and the centre is filled with insulation material.Because technological requirement, casing is provided with opening in installation site and consumable accessory replacing place of process components, leaks outside for preventing insulation material, should weld between interior outer case.And producing different thermal expansion owing to temperature contrast than conference between interior outer case, the thermal stress of generation can cause bond open or box deformation, thereby has serious consequences.
Summary of the invention
The purpose of this utility model be in solving between outer case because the different thermal expansion of the larger generation of temperature contrast causes the problem of bond open or box deformation, provide a kind of can be successful the compensation thermal walking, simple and practical, be easy to make, the syndeton for the interior outer case of tunnel-type sterilizing oven that reliability is high.
In order to achieve the above object, this utility model provides a kind of syndeton for outer case in the tunnel-type sterilizing oven, comprises internal box, outer case, it is characterized in that, described internal box is connected expansion joint with outer case and connects.
Preferably, the structure of described expansion joint is square structure.
Preferably, the edge of described expansion joint longitudinal section is stepped.
This utility model has had additional expansion joint between interior outer case, utilize the strain of expansion joint flexible element to absorb thermal deformation between the layer of sterilization tunnel high-temperature cabinet inside and outside, the thermal walking that internally produces owing to temperature contrast between the outer case compensates, avoid the generation of thermal stress, and then can avoid sterilization tunnel because weld seam explosion or the box deformation that thermal deformation produces, the assurance production safety is reliable, so that tunnel oven meets the GMP requirement more.Of the present utility model simple and practical, be easy to make, reliability is high, and can not affect the service behaviour of sterilization tunnel.

The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
Embodiment 1
This utility model is a kind of syndeton for outer case in the tunnel-type sterilizing oven, as shown in Figure 1, is a kind of partial sectional view of the syndeton for outer case in the tunnel-type sterilizing oven.Internal box 1 is connected with outer case by expansion joint 3 connections.The structure of expansion joint 3 is square structure, and the edge of expansion joint 3 longitudinal sections is stepped.
As shown in Figure 2, be the structural representation of expansion joint.Adopt the 1.2mm corrosion resistant plate to be bent into U-shaped flexible element by 4, flexible element joined end to end be welded into a square expansion joint 3, expansion joint 3 two ends are reserved and to be convenient to the flanging that welds with casing, namely expansion joint 3 interior outsides respectively with internal box 1 and outer case 2 welding in tunnel.Expansion joint 3 in this utility model adopts stainless steel, has good welding performance, can satisfy its welding process requirement in manufacturing process.
As shown in Figure 3, be the cutaway view of expansion joint.Expansion joint 3 is because the elastic deformability of its special form structure, internally the relatively hot displacement between the outer case compensates, and can according to any joint number of selecting expansion joint of the size of compensation dosage, have good operability and the widely suitability.
The expansion joint structure that this utility model provides generally is installed in feed inlet and outlet and the process components installing port place of tunnel-type sterilizing oven high-temperature area.
Claims (3)
1. a syndeton that is used for outer case in the tunnel-type sterilizing oven comprises internal box (1), outer case (2), it is characterized in that, described internal box (1) is connected 2 with outer case) connect by expansion joint (3).
2. a kind of syndeton for outer case in the tunnel-type sterilizing oven as claimed in claim 1 is characterized in that, the structure of described expansion joint (3) is square structure.
3. a kind of syndeton for outer case in the tunnel-type sterilizing oven as claimed in claim 1 is characterized in that, the edge of described expansion joint (3) longitudinal section is stepped.
