A high temperature resistant twill belt and its application

technical field

The present invention relates to twill tapes, in particular to twill structures.

Background technique

Honeycombs are heat-concentrating structures in the hearth, used as reflectors, or together with other structures to form reflectors, or as burners. A common honeycomb body is a smooth metal ring and a corrugated metal ring, which are nested from the inside to the outside to form a honeycomb shape. The stripes in this honeycomb body are generally vertical, that is, the upper and lower sides of the honeycomb body are vertically penetrated. Since the material composing the metal ring is very thin and the wave spacing of the corrugation is relatively wide, the porosity is very large. When used as a radiation plate, if the area of the reflective plate is large, the effective area of heat radiation is very small. Such a honeycomb Body radiation effect is not good.

The heating device in the electric ceramic stove is a vertical corrugated belt coiled on the stove plate according to certain rules, and the corrugated belt generates heat when it is energized.

The purpose of the present invention is to improve and innovate the shortcomings and problems existing in the background technology, and to provide a twill belt with high temperature resistance, oblique corrugation and good heat radiation effect and its application.

The technical solution of the present invention is to construct a high temperature resistant twill belt, the twill belt is provided with corrugations inclined to the overall extension direction of the twill belt, and the cross section of the twill belt is sinusoidal, square, trapezoidal or triangular waveform.

A honeycomb body applied with high temperature resistant twill tape, the whole is round or square, and is formed by superimposing a corrugated metal tape and a smooth metal tape, or a number of smooth metal rings and corrugated metal rings superimposed at intervals in the horizontal direction. The corrugated metal ring described above is formed by connecting twill strips with corrugations end-to-end.

In one of the embodiments, the metal ring is an integral structure.

The honeycomb body is solid as a whole, or the central opening of the honeycomb body is annular as a whole.

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

In one embodiment, high-temperature cotton is arranged below the honeycomb body, and the upper and lower surfaces of the honeycomb body and the high-temperature cotton are both horizontal planes, or both are curved surfaces, or both are inclined surfaces, which are curved surfaces or When inclined, the sides are high and the middle is low.

In one embodiment, the bottom of the honeycomb body is provided with a fixing member surrounding the high temperature cotton, the bottom of the fixing member is a mesh plate or a perforated plate, and the perforated plate is provided with a number of round holes, square holes or strips hole.

A stove burner using a high temperature resistant twill strip includes a honeycomb body.

A method for applying a high temperature resistant twill belt to an electric ceramic furnace, the twill belt is wound on a furnace plate according to certain rules as a heating element.

Advantages and beneficial effects of the present invention: the channel formed by the smooth metal ring and the corrugated metal ring in the honeycomb body of the present invention is an oblique channel. Radiation effect. In addition, due to longer than conventional vertical channels, the flow time of gas, mixed gas or high temperature gas in the reflector is longer, and the corresponding action time is longer, and the heat exchange is more sufficient.

Detailed ways

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the related drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It should be noted that when an element is referred to as being "disposed" on another element, it can be directly disposed or connected to the other element or intervening elements may also be present. Terms "center", "longitudinal", "lateral", "length", "width", "thickness", "top", "bottom", "front", "back", "left", "right", " The orientation or positional relationship indicated by vertical, horizontal, top, bottom, inner, outer, clockwise, and counterclockwise is based on the orientation or position shown in the drawings. Relationships are provided for ease of describing the present invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed, and operate in a particular orientation.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art of this invention. The terms used in the specification are only for the purpose of describing specific implementations, and are not intended to limit the present invention.

Example 1

As shown in Figure 1, a high temperature resistant twill tape a, the twill tape a is provided with corrugations b inclined to the overall extension direction of the twill tape a, and the cross section of the twill tape b is a sinusoidal waveform.

In practical applications, the cross section of the twill b may also be a square waveform, a trapezoidal waveform or a triangular waveform.

Example 2

The corrugation of the corrugated metal ring 3 is twill, and the cross section of the twill is A ring of sine, square, trapezoidal, or triangular waveforms. The central opening of the honeycomb body in Figures 1 and 2 is annular as a whole and is used as a reflector. If the twill honeycomb body is solid as a whole, it can also be used as a burner.

The corrugated metal ring can be formed by welding the two ends of the twill tape with twill beforehand, or it can be formed by stamping or rolling a smooth ring to form the twill, both of which are substantially the same.
