It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 2, the present application provides an electric glass furnace 100, which includes a furnace body 10, a first electrode set 12 and a second electrode set 121, wherein each of the first electrode set 12 and the second electrode set 121 includes at least one electrode 122 (e.g., a copper electrode or a molybdenum electrode), one end of each electrode 122 is inserted into the furnace body 10, and the other end is located outside the furnace body 10. In another embodiment, the number of the first electrode sets 12 is multiple, and each first electrode set 12 is arranged around the circumference of the furnace body 10; the number of the second electrode groups 121 is plural, and each second electrode group 121 is arranged around the circumference of the furnace body 10.

The furnace body 10 is provided with a cavity, the side wall of the furnace body 10 is provided with a plurality of electrode holes 11 communicated with the cavity, the electrode 122 is spatially provided with a length direction, one end of the electrode 122 along the length direction thereof extends into the cavity from the mounting hole 211, and the other end is positioned outside the furnace body 10 and is connected with an external power supply. The ends of the electrodes 122 extending into the furnace body 10 are discharged to each other, thereby melting the glass raw material. In another embodiment, the electrode 122 is cylindrical, and the cross section of the electrode hole 11 is circular; the extending direction of the electrode hole 11 is linearly arranged, and when the electrode 122 extends into the electrode hole 11, the length direction of the electrode 122 is arranged in parallel with the extending direction of the electrode hole 11.

In the present embodiment, the electrodes 122 in the first electrode group 12 are higher than the electrodes 122 in the second electrode group 121 in the vertical direction, wherein the second electrode group 121 is adjacent to the bottom of the furnace body 10. When the glass raw material enters the furnace body 10, the glass raw material is heated through the first electrode group 12 and the second electrode group 121, and the glass raw material is uniformly heated in the furnace body 10, so that the heating efficiency of the glass electric kiln 100 is improved, and the energy consumption is reduced.

When the glass material is introduced into the furnace body 10, the first electrode group 12 and the second electrode group 121 heat the glass material simultaneously, and the second electrode group 121 can preheat the glass material at the bottom of the furnace body 10 in advance. After the glass raw material is heated and melted, the second electrode group 121 may continuously heat the glass liquid to prevent the glass liquid from being doped with the unmelted glass raw material. Of course, the second electrode group 121 may be turned off.

The glass raw materials settle at the bottom of the furnace body 10, and when the first electrode group 12 heats and melts the glass raw materials, the glass raw materials below the first electrode group 12 may not be melted due to the limited heating range of the first electrode group 12 in the vertical direction, so that the glass liquid flowing out of the glass electric kiln 100 may be doped with the unmelted glass raw materials. The second electrode group 121 can increase the heating range of the glass electric kiln 100 in the vertical direction, and avoid influencing the doping of unmelted glass raw materials in the glass liquid flowing out of the glass electric kiln 100.

In another embodiment, the first electrode set 12 is 30cm to 60cm higher than the second electrode set 121. Preferably, the first electrode set 12 is 35cm higher than the second electrode set 121.

In another embodiment, the feeding opening 13 extends in a direction parallel to the moving direction of the body 41. For example: the extending direction of the feeding port 13 and the moving direction of the machine body 41 are both along the horizontal direction.

If the glass raw materials are not melted in time, the glass raw materials are accumulated in the glass electric kiln 100, and in the process that the feeding device 40 continuously feeds materials, the glass raw materials accumulated in the glass electric kiln 100 push the feeding device 40 to extend into one end of the cavity, so that the feeding device 40 is damaged. In order to solve the technical problem, referring to one embodiment, the body 41 is movable, and the feeding section 42 movably extends into the furnace body 10. When the glass raw material accumulated in the glass electric kiln 100 pushes the feeding section 42 to extend into the cavity, the feeding section 42 is subjected to a certain acting force along the direction of the feeding port 13, and at this time, the machine body 41 and the feeding section 42 move together back to the furnace body 10, so as to prevent the feeding section 42 from being damaged.

In order to avoid heat loss from the feeding section 42 to the feeding port 13 in the furnace body 10, the feeding section 42 is attached to the inner wall of the feeding port 13 according to one embodiment. In the present embodiment, the feeding opening 13 has a circular radial profile; the feeding section 42 is circular along its radial outer contour.

In order to stably feed materials into the furnace body 10, referring to one embodiment, the number of the feeding devices 40 is at least two, and the two feeding devices 40 are arranged at intervals along the circumferential direction of the furnace body 10. In some embodiments, the central angle of two adjacent feeding devices 40 along the circumferential direction of the furnace body 10 is 15 to 30 degrees. It should be explained that the circle center corresponding to two adjacent feeding devices 40 is the geometric center of the cavity in the horizontal direction.

In another embodiment, the glass electric kiln 100 further comprises a guide rail 15, the guide rail 15 extends along the axial direction of the feeding opening 13, and the body 41 can move along the guide rail 15. In order to enable the body 41 to stably move along the guide rails 15, reference is made to one embodiment in which the number of the guide rails 15 is at least two arranged side by side; a plurality of rollers 43 are rotatably mounted on the bottom of the body 41, and each roller 43 is engaged with a corresponding guide rail 15. The body 41 moves along the guide rail 15 through the roller 43 to reduce the friction between the body 41 and the guide rail 15, so that the body 41 can move along the guide rail 15 when the feeding section 42 is subjected to a small force.

The number of the guide rails 15 is at least two, including two or more. In the present embodiment, the number of the guide rails 15 is two. The number of the rollers 43 is four, and four rollers 43 are provided at the bottom of the body 41 to be able to support the body 41. In another embodiment, the glasselectric kiln 100 further comprises a bearing table 14, and the guide rails 15 are mounted to the bearing table 14. The susceptor 14 may be connected to the outer side wall of the furnace body 10, or may be provided independently of the furnace body 10.

In the specific arrangement of the feeding section 42, referring to one of the embodiments, as shown in the figure, the feeding section 42 includes a driving shaft 421, a helical blade 422 and a mounting cylinder 423; the axial direction of the driving shaft 421 is parallel to the extending direction of the feeding port 13, and is rotatably mounted on the machine body 41; the helical blade 422 is disposed outside the drive shaft 421 in the axial direction of the drive shaft 421; the mounting cylinder 423 is mounted on the body 41 and sleeved outside the helical blade 422. Wherein, the inlet and the outlet of the feeding section 42 are both positioned in the mounting cylinder 423; the mounting cylinder 423 has an axial direction which is arranged parallel to the extending direction of the charging port 13. In some embodiments, the mounting cylinder 423 is axially centered through the feed opening 13.

The glass raw material enters the spiral blade 422 through the inlet, the driving shaft 421 rotates together with the spiral blade 422, and the glass raw material at the spiral blade 422 moves towards the outlet until the glass raw material is separated from the outlet. In order to rotate the driving shaft 421, in another embodiment, the feeding device 40 further includes a motor 424, and the motor 424 is mounted to the body 41 and is used for rotating the driving shaft 421. The motor 424 has an output shaft that is connected to the drive shaft 421.

In order to solve the technical problem that when the height of the feeding section 42 or the angle along the feeding port 13 changes, the feeding section 42 may be jammed with the feeding port 13, so that the machine body 41 and the feeding section 42 cannot move, in this embodiment, as shown in the figures, the feeding device 40 further includes an adjusting assembly 50, and the adjusting assembly 50 includes a base 51 installed on the machine body 41, an installation block 52 installed on the base 51 in a sliding manner and used for installing the roller 43, and an adjusting rod 53 connected to the base 51 and capable of driving the installation block 52 to slide.

The adjusting assembly 50 adjusts the height and angle of the feeding section 42 by adjusting the height and angle of the body 41. Specifically, when the base 51 moves, the adjusting rod 53 drives the mounting block 52 to move synchronously, and the mounting block 52 drives the roller 43 to adjust the relative position between the roller 43 and the machine body 41 (e.g., the distance between the roller 43 and the machine body 41 in the vertical direction). In another embodiment, the mounting block 52 is slidably mounted to the base 51 in a vertical direction.

In the present embodiment, as shown in fig. 10 and 11, each roller 43 is independently provided with an adjustment unit 50 so that each roller 43 can be adjusted individually. Each mounting block 52 is fixed with a rotating shaft 54 extending in the horizontal direction, and each roller 43 is rotatably mounted on the corresponding rotating shaft 54. In another embodiment, one of the mounting block 52 and the base 51 is provided with a slide rail 55, the other is provided with a slide block 56 cooperating with the slide rail 55, and the mounting block 52 moves along the base 51 through the cooperation of the slide rail 55 and the slide block 56, so as to be able to define the moving path of the mounting block 52. In some embodiments, there are two sliding rails 55, and the two sliding rails 55 are fixed to the base 51 and located at two opposite sides of the mounting block 52; the number of the sliding blocks 56 is two, and the two sliding blocks 56 are disposed on two opposite sides of the mounting block 52 and respectively matched with the corresponding sliding rails 55.

In order to fix the relative position of the adjusting rod 53 and the base 51, referring to one embodiment, the adjusting assembly 50 further includes at least two screw members 57 screwed on the adjusting rod 53, and two adjacent screw members 57 clamp at least a portion of the structure of the base 51 to fix the relative position of the adjusting rod 53 and the base 51. After the position of the adjustment lever 53 on the base 51 is adjusted to a desired position, the adjustment lever 53 can be fixed to the base 51 by screwing the two screws 57. The screw 57 has a through hole through which the adjusting rod 53 passes; at least part of the outer side wall of the adjusting rod 53 is provided with an external thread, and an internal thread meshed with the external thread is arranged inside the through hole of the screw connector 57.

In order to reinforce the structural strength of the adjustment assembly 50, the components of the adjustment assembly 50 are made of a metal material. In some embodiments, the base 51 is a frame structure with the mounting block 52 located within the frame structure; one end of the adjustment rod 53 is located within the frame structure and the other end passes through and extends out of the frame structure, and two screw connections 57 are located on both sides of the frame structure.

When the base 51 is a rectangular frame structure, it includes two supporting plates 511 sequentially arranged along the vertical direction, wherein one supporting plate 511 is provided with a through hole for the adjusting rod 53 to pass through, and two screw fasteners 57 are located on two sides of the supporting plate 511.

The part of the feeding section 42 extending into the cavity is heated in the furnace body 10, and the heat of the part is transferred to the machine body 41, so that the components (such as the motor 424) on the machine body 41 are damaged, or the operator is burned when operating the machine body 41. In order to solve the technical problem, in this embodiment, a water cooling jacket 30 is disposed between the furnace body 10 and the feeding section 42, the water cooling jacket 30 is mounted on a side wall of the furnace body 10 and is sleeved outside the feeding section 42, and the water cooling jacket 30 in the above embodiments is adopted as the water cooling jacket 30.
