[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1 As shown, a hazardous waste inert gas explosion-proof stirring furnace comprises a furnace body 1, wherein a furnace chamber 3 with an opening at the front side is provided inside the furnace body 1, and a sealing door 2 for sealing the opening of the furnace chamber 3 is arranged at the front side of the furnace body 1. The front side mentioned above is only a preferred one, and can also be arranged at the upper side;

[0026] An inert gas conveyor and an exhaust pump connected to the furnace chamber 3 are also provided on the furnace body 1. The inert gas conveyor includes a gas cylinder storing inert gas. The gas cylinder and the furnace chamber 3 are connected through an air pump and a conduit. When the hazardous waste materials are stirred inside the furnace chamber 3, the air inside the furnace chamber 3 is extracted by the exhaust pump, and then the inert gas is conveyed to the inside of the furnace chamber 3 by the air pump. The gas properties of the inert gas can be used to reduce the combustion or even explosion of the hazardous waste materials during the stirring process.

[0027] like Figure 1-2 As shown, a transmission motor 5 is installed on the furnace body 1. The transmission motor 5 is only one of the preferred transmission mechanisms, and other transmission mechanisms can also be used. The output end of the transmission motor 5 is fixedly connected to a rotating rod 6 located inside the furnace cavity 3, and the outer side of the rotating rod 6 is fixedly connected to a plurality of stirring blades 7. After the transmission motor 5 is started, the hazardous waste materials inside the furnace cavity 3 are stirred by the stirring blades 7;

[0028] The transmission motor 5 and the plurality of stirring blades 7 are equipped with a conductive group, and a rotating conductive ring electrically connected to the conductive group is installed on the outer side of the rotating rod 6, and the rotating conductive ring is electrically connected to a connecting wire. At this time, during the stirring process, the static electricity generated during the stirring process can be discharged through the conductive group, the rotating conductive ring and the connecting wire, thereby reducing the phenomenon of combustion or even explosion caused by excessive accumulation of static electricity during the stirring process.

[0029] like Figure 2-4As shown, the rotating conductive ring includes a conductive inner ring 10 fixedly connected to the outside of the rotating rod 6 and electrically connected to the conductive group. The conductive group guides the static electricity generated during the stirring process to the conductive inner ring 10. The outside of the conductive inner ring 10 is rotatably connected to a conductive outer ring 11 fixedly connected to the furnace body 1. The conductive outer ring 11 is electrically connected to the conductive inner ring 10, and the grounding wire is electrically connected to the conductive outer ring 11. The static electricity on the conductive inner ring 10 can be discharged through the conductive outer ring 11 and the grounding wire. Due to the rotational connection between the conductive inner ring 10 and the conductive outer ring 11, the impact of the rotating rod 6 on the rotating conductive ring can be reduced.

[0030] like Figure 4 As shown, a plurality of elastic conductive strips 12 located between the conductive inner ring 10 and the conductive outer ring 11 are fixedly connected to the outer side of the conductive inner ring 10, and one end of the elastic conductive strip 12 away from the conductive inner ring 10 abuts against the inner wall of the conductive outer ring 11, so that the conductive inner ring 10 and the conductive outer ring 11 are electrically connected through the elastic conductive strip 12, and the poor contact between the conductive inner ring 10 and the conductive outer ring 11 is reduced. One end of the elastic conductive strip 12 away from the conductive inner ring 10 is bent in the direction opposite to the rotation direction of the rotating rod 6, so that the elastic conductive strip 12 adapts to the rotation of the rotating rod 6, and the phenomenon of the elastic conductive strip 12 abutting against the conductive outer ring 11 when rotating is reduced.

[0031] Among them, Figure 2-3 As shown, the conductive group includes conductive sheets 8 respectively fixedly connected to a plurality of stirring blades 7, and the plurality of conductive sheets 8 are electrically connected to the conductive inner ring 10 through conductive wires 9, so that static electricity can be effectively discharged;

[0032] In order to reduce the damage caused by the contact between the conductive sheet 8, the conductive wire 9 and the hazardous waste materials, the conductive sheet 8 is fixedly connected to the side of the stirring blade 7 opposite to the rotation direction of the rotating rod 6. A wire channel is opened inside the rotating rod 6, and the conductive wire 9 is installed inside the wire channel, so as to reduce the damage to the conductive sheet 8 and the conductive wire 9 caused by the thrust generated when the rotating rod 6 and the stirring blade 7 rotate.

[0033] like Figure 1-2 As shown, in order to facilitate the stirring blades 7 to stir the hazardous waste materials inside the sealed door 2, the rotating rod 6 is arranged horizontally, that is, horizontally, and a semicircular material guide cavity 4 is opened inside the furnace body 1 and at the lower side of the furnace cavity 3. The axis of the rotating rod 6 overlaps with the center of the semicircular material guide cavity 4. During the stirring process, the hazardous waste materials inside the furnace cavity 3 will fall into the semicircular material guide cavity 4 and contact with the rotating rod 6, thereby reducing the stirring dead angle.

[0034] like Figure 2As shown, in order to better discharge the static electricity during the stirring process, the inner walls of the furnace chamber 3 and the semicircular material guide chamber 4 are fixedly connected with transversely arranged conductive cross pieces 13, one end of the plurality of conductive cross pieces 13 is electrically connected to a conductive main piece 14, and the conductive main piece 14 is electrically connected to another grounding wire. The setting of the conductive cross pieces 13 can better match the stirring of the hazardous waste materials by the stirring blades 7, thereby reducing the contact dead angles between the hazardous waste materials and the conductive cross pieces 13.

[0035] The working principle of the utility model is as follows: placing hazardous waste materials inside the furnace chamber 3, then closing the sealing door 2, and starting the vacuum pump to extract the gas inside the furnace chamber 3. After the extraction is completed, the inert gas is transported to the inside of the furnace chamber 3 through the inert gas conveyor;

[0036] After the inert gas is transported, the transmission motor 5 is started. After the transmission motor 5 is started, the hazardous waste materials inside the furnace chamber 3 are stirred by the stirring blades 7. During the stirring process, the static electricity generated during the stirring process can be absorbed by the conductive sheet 8 and the conductive cross sheet 13, and then discharged through the grounding wire.

[0037] In summary, the technical solution can reduce the combustion and explosion of hazardous waste materials during the mixing process by utilizing the stability of inert gas. The static electricity generated during the mixing of hazardous waste materials is discharged by the conductive sheet 8 and the conductive cross sheet 13, which can further reduce the combustion and even explosion of hazardous waste materials during the mixing process due to excessive static electricity accumulation.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
