Description

Preheating furnace for glass processing

Technical Field

The utility model relates to a glass processing equipment field, in particular to preheater for glass processing.

Background

In the processing process of the glass, the glass needs to be heated and quenched by a toughening furnace, so that the strength of the glass is improved. At present, glass to be processed is directly sent to a tempering furnace, the time for the glass to rise from the normal temperature to the required temperature is long, the glass is broken easily due to sudden temperature rise, the production efficiency is reduced, and certain dangerousness exists.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can improve tempering furnace efficiency and can reduce dangerous preheating furnace for glass processing to solve the problem that above-mentioned background art provided.

In order to realize the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a preheating furnace for glass processing, includes the preheating chamber, and the conveying platform runs through the preheating chamber, several hot plates are installed at the top in the preheating chamber, and the width of several hot plates is crescent along direction of transfer gradually.

Preferably, it still installs blast apparatus to preheat indoor being close to the conveying entrance, and blast apparatus includes the several tuber pipe, and the fan is installed to tuber pipe one end, and the air-out nozzle is installed to the other end, and the directional conveying bench surface of air-out nozzle's air-out direction just is the obtuse angle with the direction of transfer.

Preferably, air pipes are arranged above and below the conveying table.

Preferably, the air outlet nozzle is a flat nozzle, and the air outlet nozzles are all horizontal.

Preferably, the heating plate is composed of a plurality of heating wires.

The utility model has the advantages that:

(1) the temperature of the space in the preheating chamber is gradually increased along the conveying direction of the glass, the space is heated more and more to form preheating lines, the effect of gradually heating the glass is achieved, the glass is not suddenly heated, the danger in the temperature rising process of the glass is reduced, and the heating efficiency of a subsequent toughening furnace can also be improved;

(2) the moving direction of the hot air is opposite to the conveying direction of the conveying table, so that the preheating line is further prolonged, the glass temperature rising curve is mild and stable, and the danger in the glass temperature rising process is further reduced.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the inlet of the present invention.

The labels in the figure are: 1-preheating chamber, 2-conveying table, 3-heating plate, 41-air pipe, 42-blower and 43-air outlet nozzle.

Detailed Description

The technical solutions in the present embodiments will be clearly and completely described below with reference to the accompanying drawings in the present embodiments, which, however, should not be construed as limiting the present invention to specific embodiments, but are for explanation and understanding only:

as shown in fig. 1 and 2, the present embodiment provides a preheating furnace for glass processing, comprising a preheating chamber 1, the preheating chamber 1 being connected to a toughening furnace, and a transfer table 2 penetrating the preheating chamber 1 and the toughening furnace for transferring glass. A plurality of heating plates 3 are installed at the top in the preheating chamber 1, and the width of the heating plates 3 is gradually increased along the conveying direction. The heating plate 3 comprises a plurality of heating wires, the heating wires adopt the prior art, the width of the heating plate 3 is changed by changing the number of the heating wires, when the plurality of heating plates 3 work, the heat production of the heating plates 3 with a large number is higher, the temperature of the preheating chamber 1 is higher closer to the tempering furnace, the space in the preheating chamber 1 is heated more and more along the conveying direction of the glass, thereby achieving the effect of gradually heating the glass, the glass can not be heated suddenly, the danger in the temperature rising process of the glass is reduced, and the heating efficiency of the follow-up tempering furnace can also be improved.

Air blowing device is still installed near the conveying entrance in preheating chamber 1, and air blowing device includes several tuber pipe 41, tuber pipe 41 is all installed to conveying platform 2 top and below, and the one end that preheating chamber 1 entry was kept away from to tuber pipe 41 is installed fan 42, and air-out nozzle 43 is installed to the other end, and air-out nozzle 43 adopts flat mouthful of nozzle, and several air-out nozzle 43 is equal level, and the directional conveying platform 2 of air-out direction of air-out nozzle 43 just is the obtuse angle with the direction of transfer, and conveying platform 2 is kept away from to the one end that fan 42 was installed to tuber pipe 41. Fan 42 adopts high temperature resistant draught fan 42, fan 42 rotates the entrance with the air conveying in preheating chamber 1 to conveying platform 2, help blowing off the impurity on glass surface, reduce the impurity quantity that gets into preheating chamber 1, avoid impurity to cause the influence to the heating wire in preheating chamber 1, and the air that blows out is steam, the direction of motion of steam is opposite with conveying platform 2's direction of transfer, further prolong the preheating line, make the glass curve of heating gentler, it is more stable, be favorable to reducing the danger of glass intensification in-process, and fan 42 operation is favorable to the heat transfer of the production of the hot plate 3 at top in preheating chamber 1 bottom in preheating chamber 1.

The electrical components in the embodiment are all electrically connected with 220V commercial power or 380V industrial power.

It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
