Description

Technical Field

[0001] The utility model relates to an electric melting furnace, in particular to a material shortage protection device for the electric melting furnace used in glass production. Background Art

[0002] An electric melting furnace is a device that uses electric energy to heat metal or alloy materials to their melting point for recycling or further processing. In an electric melting furnace, electrical energy is converted into thermal energy through resistance, and the metal or alloy material is heated to its melting point, turning it into a liquid state. The heating medium of an electric melting furnace is mainly induction current and resistance heating. The temperature of an electric melting furnace can reach very high levels. Some electric melting furnaces can be heated to over 3000°C. Electric melting furnaces are often used to melt glass in production.

[0003] In Chinese utility model patent CN220703505U, a glass electric melting furnace is disclosed, including a bottom plate, an electric furnace, a feed port, a heating tube and a discharge hopper, etc. The upper part of the bottom plate is connected to the electric furnace, the upper part of the electric furnace is connected to the feed port, the feed port is communicated with the electric furnace, the lower side of the electric furnace is connected to two heating tubes, and the lower part of the electric furnace is connected to the discharge hopper. The utility model drives the crushing rod on the rear side to rotate through a first motor, the crushing rod on the rear side rotates to drive the gear set to rotate, and the gear set rotates to drive the crushing rod on the front side to rotate, and the crushing rod crushes the glass fragments added to the electric furnace, so that the glass fragments can be added to the electric furnace more evenly in the later stage, avoiding the occurrence of large glass fragments that are not fully heated. Phenomenon, however, this solution also has certain defects, that is, like the existing electric melting furnace, there is no lack of material protection component. After the electric melting furnace releases the molten glass, if the electric melting furnace is not shut down in the first time, the empty burning heating can easily damage the furnace body. At the same time, although the feeding component of this solution solves the problem of glass fracture melting, at the same time, in the process of melting glass scraps in the glass melting furnace, it is necessary to control the uniform feeding. If the glass scraps are not fed evenly and the feeding amount is too large or too small, it will affect the discharge temperature of the glass melting furnace. However, in actual operation, it is usually manually controlled by a shovel based on experience, and it is difficult to ensure the uniformity of the feeding. Therefore, the present application provides a lack of material protection device for an electric melting furnace for glass production to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a material shortage protection device for an electric melting furnace for glass production to solve the problem that in the related scheme, the furnace body is manually closed after the material is completely discharged. If it is not closed in time, it is easy to cause the inner melting furnace to burn empty, and finally damage it.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, a feeding component is provided. When the device is used, the waste glass that needs to be recycled and forged can be placed in the device. The glass enters through the feeding hopper and is crushed by the crushing piece. The crushing roller is driven by motor 1 to rotate, and then the crushing rollers are rotated towards each other through two meshing gears to crush the glass. The glass then falls into the connecting piece and enters the conveying piece through the connecting piece for transportation. The conveying piece is powered by motor 2 to drive the spiral blades to rotate, and finally drives the broken glass into the furnace body for heating and melting. This solves the problem that the feeding is usually manually controlled by a shovel based on experience in related schemes, and it is difficult to ensure the uniformity of the feeding.

[0016] After the glass is melted, start the electro-hydraulic gate valve and place the material receiving equipment at the bottom of the discharge ramp.

This solves the problem of manually closing the furnace body after complete discharge in related solutions. If it is not closed in time, it is easy to cause the inner furnace to burn empty, which will eventually damage it. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The glass enters through the feed hopper 31 and is crushed by the crushing piece 32. The crushing roller 321 of the crushing piece 32 is driven to rotate by the motor 1 323, and then the crushing roller 321 is rotated towards each other through two meshing gears 322 to crush the glass. Then, the glass falls into the connecting piece 33 and enters the conveying piece 34 through the connecting piece 33 for conveying. The conveying piece 34 is powered by the motor 2 342 to drive the spiral blade 341 to rotate, and finally drives the broken glass into the furnace body 1 for heating and melting. After the glass is melted, the electro-hydraulic gate valve 21 is started, and the material receiving equipment is placed at the bottom of the discharge ramp 22. Then, the molten glass will squeeze the pressure plate 23, causing the pressure sensor 24 to react. Finally, after the molten glass has completely flowed out, there is no heavy object pressing the pressure plate 23. The furnace body 1 stops running through the control of the pressure sensor 24 to prevent damage to the inner velvet furnace caused by empty burning.

[0035] like Figure 3As shown, in this embodiment, the crushing member 32 includes: a crushing roller 321, two crushing rollers 321 are provided, and the two crushing rollers 321 are arranged in the feeding hopper 31; a gear 322, each crushing roller 321 is provided with a gear 322, and the two gears 322 are meshed with each other; a motor 323 is arranged on the feeding hopper 31, and the power shaft of the motor 323 is meshed with one of the crushing rollers 321; the crushing assembly can crush the complete glass to make it melt better.

The crushing piece 32 is driven by the motor 1 323 to rotate the crushing roller 321, and then the crushing roller 321 is rotated in the opposite direction through two meshing gears 322 to crush the glass, and then falls into the connecting piece 33, and enters the conveying piece 34 through the connecting piece 33 for conveying. The conveying piece 34 is powered by the motor 2 342 to drive the spiral blade 341 to rotate, and finally drives the broken glass into the furnace body 1 for heating and melting; after the glass is melted, start the electro-hydraulic gate valve 21, and place the material receiving equipment at the bottom of the discharge ramp 22, and then the molten glass will squeeze the pressure plate 23, causing the pressure sensor 24 to react.
