Description

Side-opening type operation hole sealing door of glass melting furnace

The technical field is as follows:

the utility model belongs to the technical field of float glass manufacturing and specifically relates to a glass melting furnace side open handle hole sealing door.

Background art:

the melting of glass in float glass production is accomplished in a melting furnace. Various solid powder materials are uniformly mixed according to a certain proportion and then are sent into a melting furnace, and the mixture is melted into transparent molten liquid in the melting furnace at a high temperature of more than 1500 ℃. Then the glass is shaped, annealed, cut and packaged into a finished glass product.

In order to ensure the normal operation of melting operation, a neck water bag, a stirrer, liquid level height measurement, temperature measurement and other equipment are arranged in the melting furnace, so that various holes are formed in breast walls on two sides of the melting furnace, the holes must be well sealed in order to reduce the heat dissipation of the furnace and the interference of the outside on the temperature and airflow in the furnace, and a sealing door needs to have good sealing performance and heat preservation and convenient operation.

The utility model has the following contents:

the utility model provides a side-opening operation hole sealing door of a glass melting furnace, which aims to overcome the defects in the prior art.

The application provides the following technical scheme:

the utility model provides a glass melting furnace side open handle hole sealing door, it includes and is equipped with the handle hole on the outer wall of glass melting furnace, is equipped with support, its characterized in that in the handle hole outside: the support is provided with a pair of slide rails, a sealing door correspondingly matched with the operation hole is arranged between the two slide rails, two ends of the sealing door are respectively provided with a roller wheel correspondingly matched with the slide rails, and a long brick correspondingly matched with the sealing door is arranged above the operation hole.

On the basis of the technical scheme, the following further technical scheme can be provided:

the middle lower part of the sealing door is provided with a handle.

The sealing door comprises a door body made of refractory bricks, groove bodies are respectively arranged on two sides of the upper end portion and the lower end portion of the door body, corresponding matching steel plates are arranged in the groove bodies, a set of fixing bolts penetrate between the two steel plates at the same end, the steel plates all extend out of the door body for a certain distance, and idler wheels are connected to the extending portions of the steel plates through rotating shafts.

Utility model advantage:

the utility model discloses simple structure, convenient to use, sealing performance is good, heat insulating ability advantage such as good.

Description of the drawings:

fig. 1 is a front view of the present invention;

fig. 2 is a front view of the present invention.

The specific implementation mode is as follows:

as shown in figures 1 and 2, the side-opening operation hole sealing door for the glass melting furnace comprises a rectangular operation hole b arranged on the outer wall a of the glass melting furnace, and one end of the operation hole b protrudes out of the outer wall a of the glass melting furnace for a certain distance. The outer side of the operation hole b is provided with a bracket 1, and the bracket 1 comprises upright posts 1a which are vertically distributed and arranged on the left side and the right side of the operation hole b respectively. And a horizontally distributed pull rod 1b is arranged between the two upright posts 1a, and the pull rods 1b are respectively distributed on the upper side and the lower side of the operation hole b. The pull rod 1b is I-shaped steel and is fixedly connected with the upright post 1a through the bracket brackets 1c at two ends.

The two pull rods 1b are respectively welded with a slide rail 2 distributed along the length direction of the pull rod 1b, and the slide rail 2 is provided with a convex ridge 2a along the length direction. A sealing door 3 correspondingly matched with the operation hole b is arranged between the two slide rails 2. The sealing door 3 include the door body 3a that firebrick made, be equipped with cell body 3b respectively in the both sides at door body 3 a's upper and lower both ends, be equipped with corresponding complex steel sheet 3c at cell body 3b, wear to be equipped with a set of fixing bolt 3d between two steel sheet 3c of same end, steel sheet 3c all outwards stretch out a section distance of door body 3a, be connected with gyro wheel 4 through the pivot on steel sheet 3 c's the extension portion, gyro wheel 4 has partly wheel face to stretch out steel sheet 3c, is equipped with on gyro wheel 4's wheel face and corresponds complex wheel groove 4a with convex ridge 2 a.

Handles 6 are welded to the left and right ends of the outer steel plate 3c located at the lower end of the door body 3 a. And a long brick 5 correspondingly matched with the sealing door 3 is arranged above the operation hole b, and the length of the long brick 5 is greater than that of the operation hole b. Thereby serving to prevent the problem of hot gas overflow.

Because the pull rod 1b at the lower side of the operation hole b is a load-bearing component, the sizes of the pull rod 1b and the sliding rail 2 and the corresponding matched roller 4 thereon are larger than the sizes of the pull rod 1b at the upper side of the operation hole b and the sliding rail 2 and the corresponding matched roller 4 thereon.
