Description

{An electric furnace for melting glass}

The present invention relates to an electric furnace for melting glass, and more particularly, in order to easily mount and withdraw a glass melting crucible inside the kiln, a freely movable door is installed on the front and the rear of the kiln to open the crucible. The present invention relates to an electric furnace for glass melting designed to be easily and conveniently installed and withdrawn into the interior.

In general, the furnace for melting glass consists of refractory bricks and insulating bricks, and one crucible is placed therein, the crucible is heated using a heating wire heater to dissolve the glass, and then a part of the bricks of the kiln is removed and the crucible is taken out. The maintenance and management of the kiln in this manner was very inconvenient.

The present inventors configure the detachable opening and closing doors on one side of the kiln to solve the above inconveniences. Patent application (Patent No. 0305596) was applied for the melting furnace, but it was very inconvenient to separate the removable door from the kiln in high temperature state, and it was inefficient because only one crucible could be installed inside the kiln.

The present invention was developed in view of the conventional problems, and an object of the present invention is to construct a door-type door with a handle on the front and rear of the glass melting furnace, open the door-type door of the glass melting furnace, two crucibles It is provided in the kiln to provide a glass melting furnace that can heat two crucibles at the same time.

The present invention to achieve the above object,

The crucible 11 is provided inside the kiln 1 in which the firebrick 4 is stacked inside the insulating brick 3, and the plurality of heating wire heaters 2 are mounted at regular intervals around the crucible 11. In the electric furnace for glass melting,

The front and rear of the kiln (1) is provided with a door opening and closing door (6) formed with a sight glass (7) and a handle (8), the center of the door opening and closing door (6), the fastener (10) mounted to the fastener (9) Is fixed to the fastener (9a) formed on one side of the kiln (1) is configured to move freely the door 6, a plurality of crucibles (11) through the opening and closing doors 6 formed on the front and rear of the kiln (1) It is configured to be mounted inside the kiln (1).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a glass melting furnace according to the present invention, Figure 2 is a longitudinal sectional view of the glass melting furnace according to the present invention, Figure 3 is a cross-sectional view of a glass melting furnace according to the present invention.

As shown in Figures 1 to 3,

The kiln 1 according to the present invention has a form in which firebrick 4 is laminated inside the insulating brick 3, and a discharge hole 5 is formed in the lower part of the kiln 1 to be dissolved in the crucible 11. It is designed to discharge the glass debris that is leaking in the closed state.

A plurality of heating wire heaters 2 are mounted at a predetermined interval inside the kiln 1, and the heaters 2 generate heat of high temperature when electricity is applied to the crucible 11 inside the kiln 1. It can be heated.

The front and rear of the kiln (1) is composed of a door-type opening and closing door (6) formed with a handle (8) and a sight window (7) is configured to easily open the door-type opening and closing door (6) to put the crucible (11) in and out. .

A fastener 9 is formed at the center of the door type opening and closing door 6, and two fasteners 9a are formed at one side of the front and rear sides of the kiln 1, and a 'c' shaped fastener 10 is provided. The fastener 9 of the opening / closing door 6 and the fastener 9a of the kiln 1 are fixed to each other so that the opening / closing door 6 rotates to be opened and closed.

The two crucibles 11 are easily inserted into the kiln 1 through the door opening and closing doors 6 formed on the front and rear of the kiln 1, the door opening and closing doors 6 are closed, and electricity is supplied to the heating wire heater 2. If the glass is dissolved in the crucible 11, it can be visually confirmed through the sight glass 7 of the door type opening / closing door 6.

In addition, when the glass is completely dissolved in the crucible 11 inside the kiln 1, the door type door 6 is opened and the crucible 11 can be easily pulled out to form molten glass into a product. Installation and withdrawal work is very convenient, but by heating two crucibles 11 at a time, it is possible to minimize the use of power by increasing the thermal efficiency and to maintain the kiln (1) with a minimum number of people.

Of course, it should be included in the present invention to mount and heat the plurality of crucibles 11 inside the kiln 1 in which the door type opening and closing doors 6 are formed on both the front or the rear and the front and the rear of the kiln 1. .

As described above, according to the present invention, the crucible 11 can be easily installed and withdrawn by configuring the door type opening / closing door 6 on the front and rear of the kiln 1, thereby maintaining, repairing, and managing the kiln 1. Simple, by heating the two crucibles 11 at a time can dissolve a large amount of glass can minimize the use of power can be maximized the external competitiveness of the glass products.
