[0003] In the related art, the crucible temperature is controlled by connecting a transformer, a copper rod, a copper busbar, an electrode clamp and a crucible electrode. The transformer power is controlled by a PLC system to heat the crucible. The contact area between the electrode clamp and the crucible electrode will affect the melting rate of the crucible, as well as the life of the crucible and the electrode clamp.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 making creative work are within the scope of protection of this application.

[0028] An embodiment of the present application provides a crucible electrode clamp, which can solve the problem of insufficient contact area between the electrode clamp and the crucible electrode in the related art, which not only affects the melting rate and production efficiency of the crucible, but also leads to poor cooling effect of the contact surface between the electrode clamp and the crucible electrode sheet, thus affecting the service life of the electrode clamp and the crucible.

[0029] See also Figure 1-Figure 8 A crucible electrode clamp, comprising: a fixed plate 1, an electrode gap 2 for clamping a crucible electrode sheet is provided at the lower end of the fixed plate 1, a clamping assembly 3 for adjusting the width of the electrode gap 2 is provided on the fixed plate 1, a cooling assembly 4 is provided on the fixed plate 1, the cooling assembly 4 comprises a water inlet channel 41, a water inlet 42 and a water outlet 43, the water inlet 42 and the water outlet 43 are provided on one side of the fixed plate 1, the water inlet channel 41 is provided in the fixed plate 1 and corresponds to the electrode gap 2, the two ends of the water inlet channel 41 are respectively communicated with the water inlet 42 and the water outlet 43, and two groups of copper bar connection holes 5 are provided on the fixed plate 1;

[0030] In this way, when in use, the staff can sleeve the fixing plate 1 on the electrode sheet of the crucible so that the electrode sheet is located in the electrode gap 2, and then adjust the width of the electrode gap 2 through the clamping assembly 3 to reduce the width of the electrode gap 2, so that the electrode sheet can be clamped and fixed through the electrode gap 2, thereby fixing the fixing plate 1 on the electrode sheet and making the fixing plate 1 and the electrode sheet fit tightly, and then the two copper busbar connecting holes 5 on the fixing plate 1 can be connected to the transformer through the soft copper busbar and the copper rod, so that the transformer transmits a certain power voltage to the crucible through the copper rod, the soft copper busbar, and the fixing plate 1 to heat it;

[0031] In this way, the fixing plate 1 and the electrode sheet can be fully fitted and contacted through the electrode gap 2, and the contact area between the fixing plate 1 and the electrode sheet can be increased. This can not only increase the heating surface of the crucible, but also make the crucible temperature more uniform to ensure the melting rate and production efficiency of the crucible. At the same time, the heat generated by the electrode sheet can be more quickly conducted to the fixing plate 1 through the contact surface, thereby accelerating the cooling effect of the contact surface between the fixing plate 1 and the crucible electrode sheet.

[0032] When in use, the staff can also connect the water pipe to the water inlet 42 and the water outlet 43, and then introduce water into the water pipe through the water supply equipment, so that the water flows into the water inlet channel 41 through the water inlet 42, and finally flows out through the water outlet 43, so that the cooling water can continuously flow in the water inlet channel 41, so that the contact surface of the fixed plate 1 and the electrode sheet can be cooled and lowered by the cooling water, so that the service life of the device and the crucible can be guaranteed;

[0033] At the same time, by hiding the water inlet channel 41 in the fixing plate 1, the device can not only reduce the volume of the device, so that the device can be installed and used in a small space, but also ensure the structural strength of the water inlet channel 41 itself to avoid damage during long-term use, thereby ensuring the service life of the water inlet channel 41 and having strong practicality.

[0034] See also Figure 7-Figure 8 The clamping assembly 3 includes a bolt 31, a nut 32 and a through hole 33. The through hole 33 is provided on the fixing plate 1 and passes through the electrode gap 2. The bolt 31 is inserted into the through hole 33. The nut 32 is sleeved on the bolt 31 and is threadedly connected thereto.

[0035] In this way, when in use, the staff can insert the bolt 31 into the through hole 33, and then put the nut 32 on the bolt 31. In this way, the staff can move the nut 32 on the bolt 31 through the threaded connection between the nut 32 and the bolt 31 by screwing the nut 32, so that the width of the electrode gap 2 is reduced through the cooperation and extrusion of the bolt 31 and the nut 32, so that the fixing plate 1 and the electrode sheet are tightly fitted, so as to fix the fixing plate 1 on the electrode sheet. Conversely, loosening the nut 32 can reset the electrode gap 2, so as to separate the fixing plate 1 from the electrode sheet, which facilitates the disassembly and assembly of the device.

[0036] See also Figure 3-Figure 4 In this embodiment, the water inlet channel 41 includes a connecting channel 411 and two groups of cooling channels 412. The two groups of cooling channels 412 are symmetrically arranged on both sides of the electrode gap 2. The cooling channels 412 include a first channel 4121, a second channel 4122 and a third channel 4123. The axes of the first channel 4121 and the second channel 4122 are parallel to the length direction of the electrode gap 2. The lengths of the first channel 4121 and the second channel 4122 are greater than the length of the electrode gap 2. The two ends of the third channel 4123 are respectively connected to the bottom ends of the first channel 4121 and the second channel 4122. The two ends of the connecting channel 411 are respectively connected to the top ends of the two groups of second channels 4122. The top ends of the two groups of first channels 4121 are respectively connected to the water inlet 42 and the water outlet 43;

[0037] In this way, when in use, the cooling water can enter one of the groups of first channels 4121 through the water inlet 42, and then enter another group of second channels 4122 along the third channel 4123, the second channel 4122 and the connecting channel 411, and then the cooling water continues to flow through another group of third channels 4123 and the first channel 4121, and finally flows out through the water outlet 43, so that the cooling water can flow in the fixed plate 1 to cool the contact surface between the fixed plate 1 and the electrode sheet, and at the same time, the tortuous design of the water inlet channel 41 can increase the contact area between the cooling water and the electrode gap 2, so as to cool down both sides of the electrode sheet, so that the cooling water can contact the fixed plate 1 more evenly and fully, so that the fixed plate 1 can be cooled more evenly, so as to enhance the cooling effect on the contact surface between the fixed plate 1 and the electrode sheet, thereby ensuring the service life of the device and the crucible, and having strong practicality.

[0038] See also Figure 5-Figure 6 , one end of the first channel 4121, the second channel 4122, the third channel 4123 and the connecting channel 411 all penetrate the fixed plate 1 and communicate with the outside, the outer ends of the first channel 4121, the second channel 4122, the third channel 4123 and the connecting channel 411 are all provided with a filling column 44, the outer ends of the first channel 4121, the second channel 4122, the third channel 4123 and the connecting channel 411 are all provided with an internal thread, the filling column 44 is provided with an external thread threadedly connected to the internal thread, and the end of the filling column 44 away from the fixed plate 1 is provided with a hexagonal groove 441;

[0039] In this way, when the device is produced, the first channel 4121, the second channel 4122, the third channel 4123 and the connecting channel 411 can be opened on the fixing plate 1 by drilling equipment, so that each channel is connected together. Then, the staff can use tools to plug the leaking ends of each channel through the threaded connection between the filling column 44 and the fixing plate 1, so that multiple channels are combined to form the water inlet channel 41;

[0040] This not only facilitates the processing of the water inlet channel 41, but also allows the water inlet channel 41 to be hidden in the fixed plate 1. When in use, there is no need to use external pipelines, which can reduce the space occupied by the device and enable the device to be used in narrow spaces, thereby enhancing the applicability of the device. At the same time, the water inlet channel 41 can be in contact with the fixed plate 1 more evenly and fully to ensure the cooling effect on the fixed plate 1. During use, the external pipeline can be prevented from being accidentally damaged by collision, and the structural strength and service life of the water inlet channel 41 can be ensured, thereby having strong practicality.

[0041] Specifically, in this embodiment, the outer end of the filling column 44 is provided with a weld 442 connected to the fixing plate 1;

[0042] After the filling column 44 blocks the channel, the filling column 44 and the fixing plate 1 can be welded together through the weld 442, thereby ensuring the sealing effect of the water inlet channel 41;

[0043] The fixing plate 1 and the filling column 44 are both made of copper material, which not only ensures the heat dissipation effect of the device, but also makes the same material easier to weld and more convenient to use.

[0044] Preferably, the outer end of the filling column 44 is chamfered;

[0045] In this way, the contact area between the filling column 44 and the weld 442 can be increased, thereby ensuring the welding strength of the filling column 44 and the sealing of the device, which is highly practical.

[0046] Wherein, the water inlet 42 and the water outlet 43 are both threadedly connected with a water pipe joint 45;

[0047] In this way, the staff can connect the water pipe through the water pipe joint 45, and disassemble and assemble the water pipe joint 45 through the threaded connection between the water pipe joint 45 and the water inlet 42 and the water outlet 43, which is convenient for replacing the water pipe joint 45 and for use.
