Background

The production process of the toughened glass mainly comprises heating treatment and cooling treatment. The glass heating furnace on the existing toughened glass production line is generally an electric heating furnace, and mainly comprises a shell, a heat insulation layer, a hearth, an electric heating wire and a control system.

In the chinese patent document, a glass tempering furnace is disclosed, with patent number CN201420183610.5, in which the electric furnace wire (resistance wire) of the glass tempering furnace, the outgoing wires at both ends directly contact with the insulating layer and the shell, and when in actual use, the temperature of the terminal is high, which not only causes energy loss, but also easily burns out the electric furnace wire.

SUMMERY OF THE UTILITY MODEL

According to the deficiency of the prior art, the utility model provides an electric furnace wire structure for glass tempering furnace.

In order to solve the technical problem, the utility model provides a glass tempering furnace electric stove silk improvement scheme, including furnace casing, heat preservation and mount pad, the heat preservation is fixed to be set up on furnace casing inner wall, and the heat preservation includes heat preservation and lower heat preservation, go up the heat preservation and include a set of electrothermal structure down in between the heat preservation at least.

Preferably, the electric heating structure consists of an electric furnace wire and a protective sleeve, wherein wire outlet ends are arranged on two sides of the electric furnace wire, penetrate through the heat insulation layer and extend out of the outer side of the furnace shell, and the protective sleeve is fixedly sleeved at the contact position of the wire outlet ends, the heat insulation layer and the furnace shell.

Preferably, the electric heating structures comprise two groups which are symmetrically arranged in the furnace shell from top to bottom.

Preferably, the protective sleeve is a copper pipe, and two ends of the copper pipe are welded with the base material of the electric furnace wire in a fusion mode.

Preferably, one end of the copper pipe is located inside the heat preservation layer, the other end of the copper pipe extends out of the outer side of the furnace shell, the length of the copper pipe reaches the outermost side of the wire outlet end, and the output wiring terminal of the wire outlet end is connected with the copper pipe.

The gain effect is as follows: the utility model discloses the suitable copper pipe of fixed suit length on the wire outlet end of the both sides of electric stove silk, can reduce the current in this department square like this, the effectual condition that reduces the leading-out terminal and generate heat makes the wire outlet end department temperature of electric stove silk reduce, has solved the problem that the leading-out terminal generates heat basically, has prolonged the life of electric stove silk.

Drawings

The present invention will be further explained with reference to the drawings and examples;

fig. 1 is a schematic view of the internal structure of the present invention;

FIG. 2 is a partial schematic view of the outlet end of the electric heating structure of the present invention;

in the figure: 1 furnace shell, 201 upper insulating layer, 202 lower insulating layer, 3 electric furnace wires, 4 outlet terminals, 5 protective sleeves and 6 mounting seats.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in the figure, the electric furnace wire structure for the glass tempering furnace provided by the embodiment comprises a furnace shell, a heat insulation layer, a mounting seat and an electric heating structure;

the furnace shell 1 is supported on the ground through a mounting seat 6;

the heat insulation layer at least comprises an upper heat insulation layer 201 and a lower heat insulation layer 202 so as to improve the heat insulation effect and reduce the heat loss;

the electric heating structures, which are two groups in the embodiment, are symmetrically arranged in the furnace shell 1 and consist of furnace wires 3 and protective sleeves 5;

the electric furnace wire 3 is a resistance wire, wire outlet ends 4 are arranged on two sides of the electric furnace wire, the wire outlet ends 4 penetrate through the heat insulation layer and extend out of the furnace shell 1, and a protective sleeve 5 is fixedly sleeved at the contact position of the wire outlet ends 4 with the heat insulation layer and the furnace shell 1;
