Description

High-temperature-resistant twill band and application thereof

Technical Field

The invention relates to a twill belt, in particular to a twill structure.

Background

The honeycomb is a heat-collecting structure within the furnace, which acts as a reflector, or constitutes a reflector with other structures, or acts as a burner. One common type of honeycomb is a honeycomb of smooth metal rings and corrugated metal rings nested inside-out to form a honeycomb. The stripes in such honeycombs are generally vertical, i.e., they run vertically up and down the honeycomb. Since the material constituting the metal rings is thin and the wave pitch of the corrugations is relatively wide, the porosity is large, and when used as a radiation plate, if the area of the reflection plate is large, the effective area of heat radiation is small, and such a honeycomb body is not effective in radiation.

The heating device in the electric ceramic furnace is a vertical corrugated belt coiled on a furnace disc according to a certain rule, and the corrugated belt heats when being electrified.

In one embodiment, the metal ring is of a unitary structure.

The whole honeycomb body is solid or the center of the honeycomb body is open and the whole honeycomb body is annular.

A reflector using high temperature resistant twill strips includes a honeycomb body.

In one embodiment, the high-temperature cotton is arranged below the honeycomb body, the upper surface and the lower surface of the honeycomb body and the high-temperature cotton are both horizontal surfaces or both arc surfaces or both inclined surfaces, and when the honeycomb body and the high-temperature cotton are arc surfaces or inclined surfaces, the peripheries are high, and the middle is low.

In one embodiment, a fixing piece surrounding the high-temperature cotton is arranged at the bottom of the honeycomb body, the bottom of the fixing piece is a screen plate or a porous plate, and a plurality of round holes, square holes or strip holes are arranged on the porous plate.

A method for applying a high-temperature-resistant twill belt to an electric ceramic furnace is characterized in that the twill belt is wound on a furnace disc according to a certain rule to serve as a heating element.

The invention has the advantages and beneficial effects that: the channels formed by the smooth metal rings and the corrugated metal rings in the honeycomb body are oblique channels, the cross section generated by the oblique channels is larger, the effective radiation area can reach 100%, and the radiation effect is improved. In addition, because the vertical channel is longer than the conventional vertical channel, the flowing time of the fuel gas, the mixed gas or the high-temperature gas in the reflector is longer, the corresponding action time is longer, and the heat exchange is more sufficient.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present. The terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed in a particular orientation, and be operated.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

As shown in FIG. 1, the high-temperature-resistant twill belt a is provided with ripples b inclined to the overall extension direction of the twill belt a, and the cross section of the twill b is in a sine wave shape.

In practical application, the cross section of the twill b can also be a square wave shape, a trapezoidal wave shape or a triangular wave shape.

Example 2

As shown in fig. 2 and 3, a twill honeycomb body includes a plurality of horizontally spaced and stacked smooth metal rings 2 and corrugated metal rings 3, the corrugations of the corrugated metal rings 3 are twill, and the cross section of the twill is a ring surrounded by sine waves, square waves, trapezoidal waves or triangular waves. The honeycomb body of fig. 1 and 2 has a central opening, generally annular, which serves as a reflector. The diagonal honeycomb body can also be used as a burner if it is solid overall.

The corrugated metal ring can be formed by welding the two ends of the prior inclined corrugated belt end to end, or can be formed by stamping or rolling a smooth circular ring into inclined ribs, and the two are substantially the same.

Example 3

As shown in fig. 4, the reflector comprises the above-mentioned twill honeycomb body 1, the high temperature cotton 4 is arranged at the lower part of the twill honeycomb body 1, and the upper surface and the lower surface of the honeycomb body 1 and the high temperature cotton 4 are horizontal surfaces.

Example 4

As shown in fig. 5, unlike embodiment 2, the honeycomb body 1 and the high temperature cotton described in this embodiment have curved surfaces on the upper and lower surfaces, and the curved surfaces are high at the periphery and low in the middle.

Example 5

As shown in fig. 6, unlike embodiment 2, the honeycomb body 1 and the high temperature cotton described in this embodiment have slopes on the upper and lower surfaces, and the slopes are high at the periphery and low in the middle.

Example 6

The embodiment is that the high-temperature inclined corrugated belt made of conventional conductive and heating materials is used for replacing a vertical corrugated belt in a conventional electric ceramic furnace.

The twill honeycomb bodies in the embodiments are all round in whole, and can also be square, such as used as burners for barbecue ovens and the like.

The channels formed by the smooth metal rings and the corrugated metal rings in the honeycomb body are oblique channels, the cross section generated by the oblique channels is larger, the effective radiation area can reach 100%, and the radiation effect is improved. In addition, because the vertical channel is longer than the conventional vertical channel, the flowing time of the fuel gas, the mixed gas or the high-temperature gas in the reflector is longer, the corresponding action time is longer, and the heat exchange is more sufficient. When the electric ceramic furnace is applied, the heat efficiency is higher than that of the conventional electric ceramic furnace.
