[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0047] like Figure 1 to Figure 2As shown, the present application provides a glass electric kiln 100, including a furnace body 10, a first electrode group 12 and a second electrode group 121, wherein the first electrode group 12 and the second electrode group 121 each include at least one electrode 122 (for example, 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 groups 12 is multiple, and each first electrode group 12 is arranged around the circumference of the furnace body 10; the number of the second electrode groups 121 is multiple, and each second electrode group 121 is arranged around the circumference of the furnace body 10.

[0048] The furnace body 10 has a cavity, and the side wall of the furnace body 10 has a plurality of electrode holes 11 connected to the cavity. The electrode 122 has a length direction in space. One end of the electrode 122 along its length direction extends into the cavity through the mounting hole 211, and the other end is located outside the furnace body 10 and connected to an external power source. The ends of each electrode 122 extending into the furnace body 10 discharge relative to each other to melt the glass raw material. In another embodiment, the electrode 122 is columnar, and the cross section of the electrode hole 11 is circular; the extension direction of the electrode hole 11 is set in a straight line, and when the electrode 122 extends into the electrode hole 11, the length direction of the electrode 122 is set parallel to the extension direction of the electrode hole 11.

[0049] In this embodiment, along the vertical direction, the electrode 122 in the first electrode group 12 is higher than the electrode 122 in the second electrode group 121, wherein the second electrode group 121 is close to the bottom of the furnace body 10. When the glass raw materials enter the furnace body 10, the glass raw materials are heated by the first electrode group 12 and the second electrode group 121, and the glass raw materials are evenly heated in the furnace body 10, so as to improve the heating efficiency of the glass electric kiln 100 and reduce energy consumption.

[0050] When the glass raw materials enter the furnace body 10, the first electrode group 12 and the second electrode group 121 heat the glass raw materials synchronously, and the second electrode group 121 can preheat the glass raw materials at the bottom of the furnace body 10. After the glass raw materials are heated and melted, the second electrode group 121 can continue to heat the glass liquid to prevent the glass liquid from being mixed with unmelted glass raw materials. Of course, the second electrode group 121 can also be turned off.

[0051] The glass raw materials will settle at the bottom of the furnace body 10. 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 melt due to the limited vertical heating range of the first electrode group 12, resulting in the unmelted glass raw materials being mixed in the glass liquid flowing out of the glass electric furnace 100. The second electrode group 121 can increase the vertical heating range of the glass electric furnace 100 to avoid the unmelted glass raw materials being mixed in the glass liquid flowing out of the glass electric furnace 100.

[0052] In this embodiment, the first electrode group 12 and the second electrode group 121 are arranged in pairs; the first electrode group 12 of the same pair is symmetrically arranged around the circumference of the furnace body 10, and the second electrode group 121 of the same pair is symmetrically arranged around the circumference of the furnace body 10. The furnace body 10 is roughly columnar, and the axis of the column is vertically arranged. In order to facilitate the arrangement of the first electrode group 12 and the second electrode group 121, in another embodiment, the furnace body 10 is roughly a multi-faceted columnar structure, and each first electrode group 12 is respectively located on one side of the furnace body 10. In this embodiment, the number of the first electrode group 12 and the second electrode group 121 are both six pairs. Of course, in other embodiments, the number of the first electrode group 12 and the second electrode group 121 are both twelve pairs.

[0053] In this embodiment, the electrodes 122 in the first electrode group 12 are arranged circumferentially around the furnace body 10 and are all at the same height; the electrodes 122 in the second electrode group 121 are arranged circumferentially around the furnace body 10 and are all at the same height. In another embodiment, the first electrode group 12 is 30 cm to 60 cm higher than the second electrode group 121. Preferably, the first electrode group 12 is 35 cm higher than the second electrode group 121.

[0054] In order to prevent the first electrode group 12 and the second electrode group 121 from occupying a large space in the circumferential direction of the furnace body 10, referring to one embodiment, along the circumferential direction of the furnace body 10, the orthographic projection of the second electrode group 121 falls into the orthographic projection area of ​​the first electrode group 12. In another embodiment, the number of electrodes 122 in the first electrode group 12 is N, and the number of electrodes 122 in the second electrode group 121 is N-(1-3). In this embodiment, the number of electrodes 122 in the first electrode group 12 is 4, and the number of electrodes 122 in the second electrode group 121 is 1.

[0055] The end of the electrode 122 extending into the furnace body 10 will react with the heavy metal ions in the glass liquid, and the electrode 122 will become thinner and shorter. When the electrode 122 becomes shorter, the end of the electrode 122 will gradually approach the electrode hole 11, which may cause the high-temperature glass liquid to overflow from the electrode hole 11, affecting the use of the glass electric kiln 100. In order to solve this technical problem, Figures 1 to 8 As shown, the glass electric furnace 100 further includes a driving mechanism 20 for driving each electrode 122. When the position of the electrode 122 is adjusted, the driving mechanism 20 drives one end of the electrode 122 located in the furnace body 10 to gradually move away from the inner wall of the furnace body 10, so that the end of the electrode 122 will gradually move away from the electrode hole 11, thereby preventing the high-temperature glass liquid from overflowing from the electrode hole 11 and affecting the use of the glass electric furnace 100.

[0056] In this embodiment, the driving mechanism 20 includes a support member 21 and a driving member 22. The support member 21 has a through mounting hole 211. The driving member 22 is slidably inserted into the mounting hole 211 of the support member 21. The driving member 22 has a length direction in space. One end of the driving member 22 along its own length direction is connected to the electrode 122, and the other end extends and leaks out of the support member 21, and the leaking part is the operating part 221.

[0057] When the electrode 122 becomes shorter, the operator can adjust the position of the electrode 122 directly through the driving member 22 by holding the operating part 221, so that the electrode 122 adapts to the requirements of the glass electric kiln 100 (for example: one end of the electrode 122 located in the furnace body 10 is away from the inner wall of the furnace body 10).

[0058] The driving mechanism 20 drives the electrode 122 to move, and can adjust the length of the electrode 122 in the glass electric kiln 100. The operating portion 221 is a part of the driving member 22, and the operating portion 221 has no absolute limitation. When the driving member 22 is inserted into the supporting member 21, part of the structure of the driving member 22 is exposed outside the supporting member 21, and the exposed part of the driving member 22 is the operating portion 221.

[0059] In this embodiment, if Figures 2 to 5 As shown, the driving member 22 includes an outer cylinder 222 and an inner cylinder 223. The outer cylinder 222 is connected to the electrode 122; the inner cylinder 223 is nested in the outer cylinder 222 and engaged with the support member 21. The outer cylinder 222 and the inner cylinder 223 both have a cavity. The inner cylinder 223 can be movably inserted into the outer cylinder 222. When the inner cylinder 223 extends into the cavity of the outer cylinder 222, the outer wall of the inner cylinder 223 fits with the inner wall of the outer cylinder 222 to prevent the inner cylinder 223 from shaking along its own radial direction. Referring to one embodiment, the axes of the outer cylinder 222, the inner cylinder 223 and the support member 21 are arranged in parallel.

[0060] The specific structure of the inner cylinder 223 and the outer cylinder 222, referring to one embodiment, the inner cylinder 223 and the outer cylinder 222 both include a sleeve 225 and a sealing plate 224 that seals one end of the sleeve 225, and the other end of the sleeve 225 facing away from the sealing plate 224 is open. Among them, for the outer cylinder 222, at least part of the sealing plate 224 is connected to the electrode 122 and is made of insulating material (such as ceramic). In order to facilitate the assembly of the driving member 22, referring to one embodiment, the outer cylinder 222 is a multi-petal structure that is buckled in the radial direction.

[0061] In this embodiment, the inner cylinder 223 has a first outer flange 2233 (the first outer flange 2233 extends outwardly along the radial direction of the inner cylinder 223), and when the inner cylinder 223 extends into the outer cylinder 222, the first outer flange 2233 abuts against the end of the outer cylinder 222 to limit the position of the inner cylinder 223 inserted into the outer cylinder 222. In another embodiment, the outer cylinder 222 is provided with a second outer flange 2223 (the second outer flange 2223 extends outwardly along the radial direction of the outer cylinder 222), and the second outer flange 2223 can abut against the first outer flange 2233 and limit the maximum depth of the drive member 22 inserted into the support member 21.

[0062] In order to fix the driving member 22 and the supporting member 21, referring to one of the embodiments, the outer cylinder 222 is provided with an escape opening 2221, and the inner cylinder 223 has a block 2231 extending out of the escape opening 2221 and engaging with the supporting member 21; the inner wall of the mounting hole 211 is provided with a plurality of slots 212 cooperating with the block 2231, and the plurality of slots 212 are arranged along the extension direction of the mounting hole. After the driving member 22 moves to the predetermined position, the block 2231 on the inner cylinder 223 extends out of the escape opening 2221 and engages with the slot 212 on the supporting member 21. Referring to one of the embodiments, the slot 212 is arranged in an annular shape.

[0063] In this embodiment, when the outer cylinder 222 and the inner cylinder 223 rotate relative to each other, the block 2231 extends out of the avoidance opening 2221. The inner cylinder 223 has a relative unlocking state and a locking state, and switches between the unlocking state and the locking state during the rotation of the inner cylinder 223. The unlocking state of the inner cylinder 223 is: the inner cylinder 223 is not engaged with the support member 21, and the driving member 22 and the support member 21 can slide relative to each other; the locking state of the inner cylinder 223 is: the inner cylinder 223 is engaged with the support member 21, and the positions of the driving member 22 and the support member 21 are fixed.

[0064] In this embodiment, the inner cylinder 223 further includes a connecting arm 2232 located at the end of the inner cylinder 223 and extending axially along the inner cylinder 223; a clamping block 2231 is installed at one end of the connecting arm 2232 facing away from the inner cylinder 223. After the driving member 22 moves to the predetermined position, the clamping block 2231 moves radially along the inner cylinder 223 until the clamping block 2231 is clamped with the clamping groove 212 on the support member 21. The connecting arm 2232 is elastically arranged so that it can be deformed to drive the clamping block 2231 to move radially along the inner cylinder 223. Referring to one embodiment, the number of the connecting arms 2232 and the clamping block 2231 is multiple, and each connecting arm 2232 and the clamping block 2231 are arranged along the circumference of the inner cylinder 223.

[0065] In this embodiment, the outer cylinder 222 is provided with a slideway 2222, and the connecting arm 2232 cooperates with the slideway 2222 to limit the movement path of the block 2231. During the rotation of the inner cylinder 223 relative to the outer cylinder 222, the block 2231 can move along the slideway 2222, so that the block 2231 can extend or retract into the avoidance opening 2221. With reference to one embodiment, the slideway 2222 extends along the radial direction of the outer cylinder 222; along the circumference of the outer cylinder 222, the slideway 2222 gradually approaches the axis of the outer cylinder 222 from the avoidance opening 2221. The number of slideways 2222 is equal to the number of blocks 2231. In another embodiment, the side walls at both ends of the slideway 2222 can limit the rotation range of the inner cylinder 223.

[0066] In this embodiment, the driving mechanism 20 further includes a bracket 23, and the support member 21 is movably mounted on the bracket 23 along the extension direction of the mounting hole 211. The support member 21 is pushed, and the support member 21 gradually moves toward the outer wall of the furnace body 10, so that the driving mechanism 20 can drive the electrode 122 to move a larger stroke. The bracket 23 is fixedly mounted on the side wall of the furnace body 10; a locking member 233 is provided between the support member 21 and the bracket 23, and the locking member 233 is used to fix the relative position of the support member 21 and the bracket 23.

[0067] Regarding the matching mode of the support member 21 and the bracket 23, referring to one embodiment, the support member 21 has a slide groove, and the support member 21 is sleeved on the outer side of the bracket 23 through the slide groove. In order to prevent the support member 21 from shaking during the sliding process along the bracket 23, the outer contour of the bracket 23 is in contact with the inner wall of the slide groove, and the outer contour of the bracket 23 is non-circular to prevent the support member 21 and the bracket 23 from rotating relative to each other.

[0068] In this embodiment, a plurality of first locking holes 231 are sequentially opened on the bracket 23 along the sliding direction of the support member 21; a plurality of second locking holes 232 are sequentially opened on the support member 21 along the sliding direction of the support member 21; and the locking member 233 can pass through the corresponding first locking holes 231 and the second locking holes 232 in sequence.

[0069] When the support member 21 slides to a predetermined position, the first locking hole 231 on the bracket 23 is aligned with the second locking hole 232 on the support member 21, and the locking member 233 passes through the first locking hole 231 and the second locking hole 232. In another embodiment, the locking member 233 is a latch or a bolt.

[0070] When the electrode 122 is used for a long time, the length of the electrode 122 does not meet the use requirements. In order to solve this technical problem, refer to one embodiment, such as Figure 6 and Figure 7As shown, along the extension direction of the electrode hole 11, the electrode 122 includes at least one unit element 123 connected in sequence, and two adjacent unit elements 123 are threadedly connected. Among the two adjacent unit elements 123, one unit element 123 has a stud at the end, and the other has a threaded hole that matches the stud thread. In order to make the connection between the two adjacent unit elements 123 more stable, in some embodiments, the end faces of the two adjacent unit elements 123 are close to each other.

[0071] The portion of the electrode 122 extending into the furnace body 10 will be heated. In order to prevent the heat from being transferred to the outside of the furnace body 10, referring to one embodiment, Figure 8 As shown, the glass electric kiln 100 also includes a water cooling jacket 30 , one end of the water cooling jacket 30 along the extension direction of the electrode hole 11 is located inside the electrode hole 11 , and the other end is located outside the furnace body 10 ; the electrode 122 is movably arranged in the water cooling jacket 30 ; the water cooling jacket 30 can reduce the heat of the electrode 122 .

[0072] Regarding the specific configuration of the water-cooling jacket 30, referring to one embodiment, the water-cooling jacket 30 includes a first cylinder 31, a second cylinder 32, and a head 33; the first cylinder 31 is sleeved on the outside of the electrode 122; the second cylinder 32 is sleeved on the outside of the first cylinder 31; two groups of heads 33 are provided, and the heads 33 are arranged between the first cylinder 31 and the second cylinder 32, and form a cooling chamber with the first cylinder 31 and the second cylinder 32. Among them, the head 33 is annular, and the outer periphery of the head 33 is fixed to the second cylinder 32, and the inner periphery is fixed to the first cylinder 31.

[0073] In another embodiment, the water cooling jacket 30 further includes a water inlet pipe 34 and a water outlet pipe 35 connected to the cooling chamber. The cooling liquid (e.g., cooling water) enters the temperature-insulating chamber through the water inlet pipe 34 and then flows out through the water outlet pipe 35. The water inlet pipe 34 is connected to an external cooling source. The water inlet pipe 34 is located at the bottom of the water cooling jacket 30, and the water outlet pipe 35 is located at the top of the water cooling jacket 30.

[0074] In this embodiment, if Figure 1 and Fig. 9 As shown, the glass electric kiln 100 further includes a feeding device 40, which is located above the first electrode group 12 and is staggered along the circumference of the furnace body 10 to prevent the electrode 122 from affecting the feeding of the glass raw material by the feeding device 20 when heating the glass raw material. The furnace body 10 has a loading port 13 connected to the cavity; the feeding device 40 includes a body 41 and a feeding section 42, one end of the feeding section 42 is installed on the body 41, and the other end extends into the cavity through the loading port 13.

[0075] The feeding section 42 has an inlet and an outlet, the inlet is located outside the furnace body 10, and the outlet is located at the end of the feeding section 42 extending into the cavity (for example, the end surface of the feeding section 42 extending into the end of the cavity). The glass raw material enters from the inlet of the feeding section 42, and then is fed into the furnace body 10 from the outlet. In another embodiment, the extension direction of the feeding port 13 is parallel to the movement direction of the body 41. For example, the extension direction of the feeding port 13 and the movement direction of the body 41 are both in the horizontal direction.

[0076] If the glass raw materials are not melted in time, they will accumulate in the glass electric furnace 100. During the continuous feeding process of the feeding device 40, the glass raw materials accumulated in the glass electric furnace 100 will push the feeding device 40 into one end of the cavity, causing damage to the feeding device 40. In order to solve this technical problem, referring to one embodiment, the machine body 41 is movable, and the feeding section 42 is movable and extends into the furnace body 10. When the glass raw materials accumulated in the glass electric furnace 100 push the feeding section 42 into the part of the cavity, the feeding section 42 is subjected to a certain force along the direction of the feeding port 13. At this time, the machine body 41 will move together with the feeding section 42 to the back of the furnace body 10 to avoid damage to the feeding section 42.

[0077] In order to prevent the heat in the furnace body 10 from being lost between the feeding section 42 and the loading port 13, referring to one embodiment, the feeding section 42 is close to the inner wall of the loading port 13. In this embodiment, the radial contour of the loading port 13 is circular; the radial outer contour of the feeding section 42 is circular.

[0078] In order to stably feed materials into the furnace body 10, referring to one embodiment, there are at least two sets of feeding devices 40, and the two sets of feeding devices 40 are arranged at intervals along the circumference of the furnace body 10. In some embodiments, along the circumference of the furnace body 10, the center angle of two adjacent feeding devices 40 is 15 degrees to 30 degrees. It should be explained that the center of the circle corresponding to two adjacent feeding devices 40 is the geometric center of the cavity in the horizontal direction.
