Description

Cato structure of a ceramic protective cover

technical field

The utility model relates to the technical field of ceramic protective sleeves, in particular to a card tray structure of a ceramic protective sleeve.

Background technique

Under high temperature conditions, the detection probe structure, heating structure, or feeding and reclaiming structure that need to extend into the high temperature cavity are mostly made of metal materials. In order to be able to use it for a long time under high temperature conditions without damage, the common method is to cool the above structure with water. Although water cooling protects the equipment, it will cause heat loss in the high temperature inner cavity. At the same time, although the equipment has cooling protection, the outer surface may still not be used for a long time due to local damage caused by high temperature, so it is necessary to use a thermal protection cover outside this part of the structure. The general ceramic protective sleeve is fixed with a wire plug, but the ceramic protective sleeve is in a high temperature environment, and the main body of the structure is protected by water cooling.

Optionally, the protective cover is a straight tube, and the bottom of the structural body is provided with an outer protrusion, and the outer protrusion is supported under the straight pipe to form a card tray structure in which the protective cover is supported.

Optionally, the protective cover is a straight tube with a buckle. After the straight tube with a buckle is sleeved into the structure main body, a card tray structure is formed, and the card tray structure includes a card tray structure in which spaced protrusions overlap. and ring-shaped cato structure.

Optionally, the bracket structure in which the spaced protrusions overlap is a structure in which a straight tube with a buckle is inserted into the main body of the structure, and the straight tube with a buckle is provided with an inner protrusion arranged at intervals from the outer protrusion. , the inner protrusion overlaps the outer protrusion.

Optionally, the number of the inner protrusions is 2-6 pairs.

Optionally, the ring-shaped card holder is a structure in which a straight tube with a buckle is provided with an annular inner protrusion. After the straight tube with a buckle is sleeved into the structure body, a ring-shaped card holder is provided on the outside of the structure body.

Optionally, the card tray structure is arranged on the inner upper portion of the protective cover, or is arranged on the inner middle portion of the protective cover, or is arranged on the inner bottom of the protective cover.

Optionally, a thermal insulation material is provided between the outer side of the structural body and the protective cover, and the thermal insulation material is a refractory felt or a porous high temperature resistant ceramic material.

Compared with the prior art, the utility model has the following beneficial effects:

In the utility model, the protective cover can better protect the main body of the structure by arranging the catch structure, and a gap is reserved between the catch structure, the protective cover and the structure body, so as to avoid the dimensional change of each component caused by thermal expansion under high temperature conditions affect the stability of the structure.

FIG. 1 is a schematic structural diagram of a card tray structure in which spaced protrusions overlap according to the present invention.

FIG. 2 is a schematic structural diagram of the ring-shaped card tray structure of the present invention.

As shown in the figure: structure main body-1, protective cover-2, outer protrusion-3, inner protrusion-4, ring-shaped card holder-5, annular inner protrusion-6, fixed connection-7, Insulation material-8.

Detailed ways

The present utility model will be further described below in conjunction with accompanying

drawings

1 and 2.

As shown in FIGS. 1 and 2 , the card tray structure of the ceramic protective cover includes a structural main body 1 and a protective cover 2 , and a thermal insulation material 8 is provided between the outer side of the structural main body 1 and the protective cover 2 . The insulation material 8 is a refractory felt or a porous high temperature resistant ceramic material. Outer protrusions 3 are arranged at intervals on the outer side of the structural main body 1 , the protective cover 2 cooperates with the outer protrusions 3 to form a card tray structure, and the protection sheath 2 and the card tray structure are arranged at intervals.

When the protective cover 2 is a straight pipe, the bottom of the structure main body 1 is provided with an outer protrusion 3, and the outer protrusion 3 is supported under the protective cover 2 to form a card tray structure of the protective cover 2. The card tray structure is arranged on the inner lower part of the protective cover 2 so that the protective cover 3 is supported.

When the protective cover 2 is a straight tube with a buckle, after the straight tube 2 with a buckle is sleeved into the structure main body 1, a card tray structure is formed. The card tray structure includes a card tray structure in which spaced protrusions overlap and a ring card tray structure.

An inner protrusion 4 spaced from the outer protrusion 3 may be provided on the straight tube with the buckle. After the buckled straight tube is inserted into the structural main body 1 to be protected, the protective cover 2 is rotated so that the inner protrusions 4 and the outer protrusions 3 are rotated and overlapped to form a support structure for supporting the outer protective cover 2 .
