Detailed Description

The utility model will be described in further detail below with reference to the drawings by means of specific embodiments.

Example 1

As shown in fig. 1, the embodiment provides an electrode structure of a vacuum distillation furnace, which is used for realizing the rapid connection between the electrode 4 and the heating element 3, effectively reducing the maintenance period and maintenance cost of the electrode 4 and the heating element 3, and simultaneously effectively ensuring the tightness and heat preservation performance of the vacuum distillation furnace.

Specifically, the electrode structure includes: electrode 4, once pour body 1 and electrode pin 5, wherein, electrode one end is connected with the transformer, and the other end passes through connecting piece 6 and electrode pin 5 is connected, and electrode pin 5 locates once pours body 1 on, and stretches into the stove after once pouring body 1 is run through from once pouring body 1 outside, and its one end that stretches into the stove passes through screw 7 with heat-generating body 3 to supply power to heat-generating body 3.

The whole primary casting body 1 is formed by casting and sintering refractory materials, and can be in various forms such as square, round, arc and the like, and the specific shape is freely selected according to the furnace type and the installation position thereof, and is not limited herein. The air tightness and the heat insulation performance can be effectively ensured by adopting an integral pouring mode. The primary casting body 1 is detachably connected with the furnace body, and the specific mode is not limited herein, and is preferably: the metal shell at the position of the primary casting body 1 and the mounting position is used as an integrated structure, the metal shell at the mounting position and the rest of the shell can be fixed by adopting a flange, the metal shell can be directly disassembled and assembled and the primary casting body 1 can be disassembled and assembled, and the overhauling efficiency can be effectively improved.

Because the primary casting body 1 and the electrode pin 5 can expand at high temperature, if the electrode pin 5 is directly cast on the primary casting body 1, the electrode pin 5 and the primary casting body 1 expand at high temperature, and the electrode pin 5 and/or the primary casting body 1 are/is cracked due to mutual extrusion, so that performance is affected. Therefore, this embodiment has adopted and has set up the mounting hole that runs through to the opposite side from one side of once pouring body 1 on pouring body 1 once, and electrode pin 5 is arranged in the mounting hole, is equipped with flexible secondary pouring body 2 in the clearance between electrode pin 5 and the mounting hole pore wall, utilizes secondary pouring body 2 to seal the clearance between electrode pin 5 and the mounting hole to guarantee the gas tightness, prevent that metal gas from escaping from the clearance. Meanwhile, when the electrode pin 5 and the primary casting body 1 are hard and expand at high temperature, the flexible material provides certain buffering, so that the electrode pin 5 and/or the primary casting body 1 can be effectively prevented from being damaged due to high-temperature expansion, and the service life is prolonged.

Further, due to the influence of process errors and precision in the manufacturing process of the structure, the problem of positional deviation between the electrode 4 and the electrode pin 5 occurs, which makes the connection between the electrode 4 and the electrode pin 5 difficult, so in this embodiment, the assembling difficulty of the electrode 4 and the electrode pin 5 is reduced by adopting the special connecting piece 6. As shown in fig. 2, the connecting member 6 is integrally formed of a conductive material (preferably, graphite) and has one end fixedly connected to the electrode through an adjusting nut 61 and a locking nut 62 and the other end fixedly connected to the electrode pin 5 through a screw 7. Specifically, when the electrode 4 and the electrode pin 5 are connected, the position of the adjusting nut 61 is adjusted, then the position of the connecting piece 6 on the electrode 4 is adjusted, the hole on the other end of the connecting piece is opposite to the threaded hole on the electrode pin 5, then the locking nut 62 is screwed down again to fix the position of the connecting piece 6, and finally the connecting piece 6 and the electrode pin 5 are fixed by the screw 7. The connecting piece 6 is used for connecting the electrode 4 and the electrode pin 5, so that the assembly difficulty of the electrode 4 and the electrode pin 5 can be effectively reduced, and the maintenance efficiency is improved.
