Description

Top-inserted molybdenum electrode and cooling water jacket device

Technical Field

The present application relates to the technical field of glass processing, and in particular to a top-inserted molybdenum electrode and a cooling water jacket device.

Background Art

Glass melting furnace is a thermal equipment used to melt glass batch in glass manufacturing. With the continuous improvement of environmental protection and energy saving requirements, glass melting furnaces are gradually developing towards electric melting and full electric melting. The proportion of electric energy used is gradually increasing, while the proportion of gas used is gradually decreasing. The direct component used to melt glass batch in the glass melting furnace is the top-inserted molybdenum electrode, which is mainly composed of an electrode and an electrode water jacket. The electrode water jacket is connected to the electrode for cooling the electrode.

The conventional technology uses an indirect cooling method, that is, by connecting the head of the electrode to a stainless steel sleeve, the cooling water of the electrode water jacket contacts the stainless steel sleeve, and the electrode is cooled by heat conduction from the stainless steel. However, the temperature of the electrode head is usually high, and the liquid level of the glass liquid fluctuates during operation, which can easily cause the head part of the electrode connected to the electrode water jacket to be exposed to the air, which is then damaged by oxidation, affecting the service life of the electrode, resulting in high processing costs and long downtime due to frequent replacement of electrodes, and reducing glass production efficiency.

Summary of the invention

Based on this, it is necessary to provide a top-inserted molybdenum electrode and cooling water jacket device to address the problem of electrode oxidation damage, which leads to high processing costs and low production efficiency.

The processing electrode has a mounting end, the end surface of the mounting end is inwardly concave to form a receiving hole, at least a part of the mounting end is inserted into the first pipe end, and the water outlet pipe end is inserted into the receiving hole.

The top-inserted molybdenum electrode of this scheme is used in a cooling water jacket device. When in use, the processing electrode needs to be inserted into the glass electric melting pool, and the mounting end of the processing electrode must be immersed below the glass liquid level. By introducing cooling water into the water inlet pipe, the cooling water can flow out from the water outlet pipe end and enter the receiving hole, thereby achieving the effect of direct contact with the mounting end of the processing electrode through the cooling water, and realizing direct cooling of the mounting end of the processing electrode, so that the temperature of the mounting end of the processing electrode can be quickly and effectively cooled down to below a safe temperature (for example, 230°C). In this way, even if the glass liquid level fluctuates and the mounting end is exposed to the air, the mounting end of the processing electrode will not be oxidized and damaged due to high temperature, thereby ensuring the safety of the processing electrode, improving the service life of the processing electrode, and avoiding frequent replacement of the processing electrode, which causes increased processing costs and excessive downtime, affecting glass production efficiency.

The technical solution of this application is further described below:

In one embodiment, the mounting end includes an inserting portion and a step portion, the inserting portion is inserted into the first pipe end, and the step portion is abutted against an end surface of the first pipe end for positioning.

Referring to Figures 1 to 3, a top-inserted molybdenum electrode 100 is shown in one embodiment of the present application, which includes an electrode water jacket 10 and a processing electrode 20. The electrode water jacket 10 includes a return pipe 12 and an inlet pipe 11. The inlet pipe 11 is sleeved in the lumen of the return pipe 12. It can be understood that the inner diameter of the return pipe 12 is greater than or equal to the outer diameter of the inlet pipe 11, so that the inlet pipe 11 can be installed in the return pipe 12.

The return pipe 12 and the inlet pipe 11 can be any one of a circular pipe, a square pipe, etc., and the shapes of the return pipe 12 and the inlet pipe 11 can be the same or different. In addition, the material of the return pipe 12 and the inlet pipe 11 can be any one of plastic, metal, etc., which can be flexibly selected according to actual needs.

The water return pipe 12 has a first pipe end 121. It can be understood that the first pipe end 121 is specifically one of the pipe ends of the water return pipe 12 in the length direction.

It is necessary to explain that the "pipe end" mentioned in this article does not refer to an end face of the pipe fitting, but refers to a pipe section at one end of the pipe fitting in the length direction.

In addition, the water inlet pipe 11 has a water outlet pipe end 111, that is, the water outlet pipe end 111 is an end where cooling water is discharged from the water inlet pipe 11. The water outlet pipe end 111 is arranged corresponding to the first pipe end 121, specifically, the water outlet pipe end 111 and the first pipe end 121 are arranged at the same end of the top-inserted molybdenum electrode 100.

The processing electrode 20 has a mounting end 21 , the end surface of the mounting end 21 is inwardly recessed to form a receiving hole 211 , at least a portion of the mounting end 21 is inserted into the first pipe end 121 , and the outlet pipe end 111 is inserted into the receiving hole 211 .

In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the top-inserted molybdenum electrode 100 of this solution is applied to a cooling water jacket device. When in use, the processing electrode 20 needs to be inserted into the glass electric melting pool, and ensure that the mounting end 21 of the processing electrode 20 is immersed below the glass liquid level; by introducing cooling water into the water inlet pipe 11, the cooling water can flow out from the water outlet pipe end 111 and enter the accommodating hole 211, thereby achieving the effect of direct contact of the mounting end 21 of the processing electrode 20 by the cooling water, and realizing direct cooling of the mounting end 21 of the processing electrode 20, so that the temperature of the mounting end 21 of the processing electrode 20 can be quickly and effectively cooled down to below a safe temperature (for example, 230°C). In this way, even if the glass liquid level fluctuates and causes the mounting end 21 to be exposed to the air, the mounting end 21 of the processing electrode 20 will not be oxidized and damaged due to high temperature, thereby ensuring the safety of the processing electrode 20, improving the service life of the processing electrode 20, and avoiding frequent replacement of the processing electrode 20, which causes increased processing costs and excessive downtime, affecting glass production efficiency.

That is, as long as the temperature of the processing electrode 20 drops below a safe temperature (eg, 230° C.), even if the processing electrode 20 is exposed to air above the glass liquid level, an oxidation reaction will not occur in the exposed portion.

For example, the machining electrode 20 in the present application may be, but is not limited to, a molybdenum electrode.

Please continue to refer to Figures 2 and 3. In one embodiment, the mounting end 21 includes a plug-in portion 212 and a step portion 213. The plug-in portion 212 is inserted into the first tube end 121, and the step portion 213 is abutted and positioned with the end surface of the first tube end 121. The plug-in portion 212 is inserted into the tube cavity of the first tube end 121, so that the processing electrode 20 can be installed and fixed with the return pipe 12, and the step portion 213 is abutted with the end surface of the first tube end 121, so that the processing electrode 20 can be installed and positioned, and the assembly accuracy of the processing electrode 20 and the return pipe 12 is guaranteed.

Furthermore, the top-inserted molybdenum electrode 100 further includes a copper sleeve 30, which is sleeved on the outside of the plug-in portion 212, and the copper sleeve 30 and the plug-in portion 212 are inserted into the first pipe end 121 together, and the outer peripheral wall of the copper sleeve 30 is fixedly abutted against the inner pipe wall of the first pipe end 121. In addition, the top-inserted molybdenum electrode 100 further includes an electrical copper plate 40, and the return pipe 12 also has a second pipe end, and the electrical copper plate 40 is arranged at the second pipe end, and the electrical copper plate 40 is used to be electrically connected to the copper sleeve 30. On the one hand, the mounting end 21 of the processing electrode 20 can be more tightly sleeved on the first pipe end 121 of the return pipe 12 through the copper sleeve 30, and on the other hand, the copper sleeve 30 can also be electrically connected to the electrical copper plate 40, so as to supply power to the processing electrode 20 during production.

The electrical copper plate 40 and the copper sleeve 30 are connected by wires to achieve electrical connection. The wires can be routed from the outside of the top-inserted molybdenum electrode 100, or inside the return pipe 12 (for example, the cavity between the inner wall of the return pipe 12 and the outer wall of the water inlet pipe 11), and the specific choice can be flexible according to actual needs.

Optionally, the copper sleeve 30 is made of red copper and is a hollow cylindrical structure with two ends passing through.

The inner peripheral wall of the copper sleeve 30 is provided with an internal thread, and the outer peripheral wall of the plug-in portion 212 is provided with an external thread, and the external thread and the internal thread are screwed together so that the plug-in portion 212 and the copper sleeve 30 can be detachably connected, and the connection strength is high; during installation, the copper sleeve 30 and the processing electrode 20 can be connected as a whole first, and then assembled together with the return pipe 12, reducing the number of parts and installation steps. Of course, in other optional embodiments, the copper sleeve 30 and the processing electrode 20 can also be assembled and fixed by any of the methods such as clamping, bonding, and riveting, which can be selected according to actual needs.

Please continue to refer to FIG. 2. In addition, based on any of the above embodiments, the outer peripheral wall of the outlet pipe end 111 cooperates with the hole wall gap of the receiving hole 211 to form a drainage channel 50, and the outer peripheral wall of the outlet pipe end 111 is provided with a plurality of water outlet holes distributed at intervals. During production, the cooling water in the water inlet pipe 11 can be sprayed from the plurality of water outlet holes to different parts of the mounting end 21 of the processing electrode 20 at the same time, so that the mounting end 21 can be quickly and effectively cooled. After the cooling water sprayed from the water outlet hole cools the mounting end 21, it can carry the heat and be discharged from the receiving hole 211 in time through the drainage channel 50, so as to ensure that the low-temperature or normal-temperature cooling water sprayed from the water outlet hole can continuously perform heat exchange cooling on the mounting end 21 of the processing electrode 20, ensure the cooling effect of the processing electrode 20, and avoid oxidation damage caused by the mounting end 21 being exposed to the air due to excessive temperature.

Please continue to refer to FIG. 2. Further, the outer wall of the water inlet pipe 11 and the inner wall of the water return pipe 12 are gap-matched to form a water return channel 60, and the water return channel 60 is connected to the drainage channel 50. The cooling water carrying high temperature heat flowing into the drainage channel 50 will further flow into the water return channel 60, and then be easily discharged from the water return pipe 12. For example, the cooling water discharged from the water return pipe 12 will flow back to the cooling water circulation device, so that the cooling water can be recycled and reused, thereby improving the utilization rate of water resources and reducing production costs.

In another embodiment, the top-inserted molybdenum electrode 100 further includes a water return distribution plate 70, which is sleeved and fixed on the outside of the water inlet pipe 11, and the outer peripheral wall of the water return distribution plate 70 is sealed or gap-matched with the inner pipe wall of the water return pipe 12, and the water return distribution plate 70 is provided with at least one circle of water return holes arranged at intervals along the circumferential direction. The cooling water in the drainage channel 50 can flow into the water return channel 60 more efficiently and evenly through at least one circle of water return holes, thereby improving the flow efficiency of the cooling water and strengthening the continuous cooling effect of the electrode water jacket 10 on the processing electrode 20.

Preferably, each circle of water return holes includes a plurality of water return holes, and a total of a plurality of circles of water return holes spaced apart in the radial direction are provided to further improve the flow efficiency of the cooling water from the drainage channel 50 to the water return channel 60 .
