Description

Crucible connecting device and material processing equipment and system

Technical Field

The application relates to the technical field of crucibles, in particular to a crucible connecting device, material processing equipment and a material processing system.

Background

The crucible can be a high temperature heat treatment of the material, for example, the crucible can be a cold crucible. The cold crucible glass solidification technology has the characteristics of high working temperature, wide treatment range, long service life, uniform melt, small equipment volume, easy retirement and the like. The cold crucible glass solidification technology can be used for low and medium level radioactive wastes such as solid wastes, resin, concentrates and the like generated by a nuclear power station; it can also be used for high-level radioactive waste liquid and other wastes which are hard to treat and have strong corrosiveness. Therefore, the development of this technology has received much attention. In nuclear power operation, a large amount of radioactive waste must be produced. The spent fuel post-treatment and the high-level radioactive waste liquid generated by the spent fuel post-treatment have the characteristics of high radioactivity ratio, high heat release rate, containing some nuclides with long half-life period and high biological toxicity and the like, so the treatment and the disposal of the spent fuel become one of the key problems for restricting the sustainable development of nuclear power and nuclear fuel cycle industry. The cold crucible glass solidification technology is a new nuclear waste treatment technology, and has unique advantages in the aspects of nuclear waste and high-level radioactive waste liquid treatment.

The cold crucible is a circular or oval container composed of a plurality of arc blocks or pipes, cooling water is introduced into the arc blocks or pipes to keep a cold wall, gaps among the arc blocks or pipes are filled with insulating substances, the materials in the cold crucible are heated through an electromagnetic field, and a water-cooling coil formed by winding a copper pipe is arranged outside the cold crucible. Because the cold crucible adopts a water cooling structure, a solid glass shell layer is formed in a region close to the cooling pipe with low temperature, and the cold crucible is prevented from being corroded by the molten material. The cold crucible glass curing system mainly comprises: the system comprises a cold crucible, a feeding subsystem, a glass discharging subsystem, a flue gas purification subsystem, an instrument control system and the like. The cold crucible glass curing process mainly has three forms, which are respectively as follows: a two-step glass curing process, a one-step glass curing process and a one-step burnt glass curing process. The two-step glass curing process is that waste liquid is calcined in a calcining furnace and then mixed with glass base material, and the mixture is sent to a cold crucible; the one-step glass curing process is that the waste liquid and the glass base material are directly sent into a cold crucible; the one-step glass burning and solidifying process includes mixing solid combustible waste with glass base material and feeding the mixture into cold crucible. The first two processes are mainly used for treating waste liquid, and the latter process is mainly used for treating solid waste.

The electromagnetic cold crucible can be divided into 2 types of batch type and continuous casting type according to different use modes, but the basic principle is the same, and the electromagnetic cold crucible mainly comprises a water-cooled crucible, a power supply and other auxiliary facilities. A spiral induction coil is wound outside the crucible and is connected with a power supply to generate an alternating electromagnetic field. When the coil is energized with an alternating current, 1 alternating electromagnetic field is generated inside and around the coil. Since each metal tube of the cold crucible is insulated from each other, an induced current is generated in each tube. When the instantaneous current of the induction coil is in the anticlockwise direction, the induced current in the clockwise direction is simultaneously generated in the section of each tube, the current directions on the sections of two adjacent tubes are opposite, the directions of the magnetic fields established between the tubes are the same, and the magnetic field enhancement effect is outwards expressed. Therefore, each gap of the cold crucible is provided with 1 strong magnetic field, the cold crucible is like a strong current device, magnetic lines of force are gathered on materials in the crucible, and the materials in the crucible are cut by the magnetic lines of force of the alternating magnetic field. According to the electromagnetic field theory, induced electromotive force is generated in the material in the crucible, and a closed current loop is formed in a thin layer on the surface of a melt of the material due to the existence of the induced electromotive force. This current is commonly referred to as eddy currents, the magnitude of which obeys ohm's law. Since the resistance of the eddy current circuit is usually small, it can reach high values, causing the eddy current circuit to generate a large amount of heat, which can be determined by ohm's law, and thus melting the metal.

The electromagnetic field of the cold crucible is generated by an induction coil which is connected to a power supply to generate an alternating electromagnetic field, whereby the power supply is essential for the proper operation of the cold crucible. The power supply of the cold crucible can be a high-frequency power supply which adopts an electronic tube as a main electronic device. At present, the novel high-frequency induction heating power supply driving circuit developed by an insulated gate bipolar transistor (I GBT) or a power field effect transistor (MOSF ET) is widely applied. The I GBT is taken as a power supply driving circuit of a main electronic device, a high-frequency power supply induction system in a cold crucible glass solidification device is required to have higher frequency and larger output power, and the characteristics of the MOS FET driving circuit are relatively in line with the requirements of the technology. The circuit has the advantages of simple structure, high working frequency, low cost, easy realization, small time delay, strong anti-interference capability and the like.

The crucible can heat the radioactive materials, the heat of the crucible needs to be provided by a power supply, and the power supply needs to be controlled, adjusted, maintained, switched and other various operations by an operator. In the related art, when the crucible is operated, radioactive substances easily enter a space corresponding to a power supply, so that operators are harmed.
