Description

Technical Field

[0001] The utility model relates to the technical field of plasma furnaces, and particularly relates to a multi-station device of a plasma furnace with a protection structure. Background Technique

[0002] Plasma, also called plasma, is an ionized gaseous substance composed of positive and negative ions generated after some electrons are stripped from atoms and atomic groups. It is a macroscopic electrically neutral ionized gas with a scale larger than the Debye length. Its movement is mainly dominated by electromagnetic force and exhibits significant collective behavior. Plasma is a good conductor of electricity. By using a cleverly designed magnetic field, plasma can be captured, moved and accelerated. The development of its physics provides new technologies and processes for the further development of sciences such as materials, energy, information, environmental space, space physics, and geophysics. A plasma furnace is a device containing non-solid, liquid or gaseous plasma. The working principle of a plasma furnace mainly depends on the high-temperature characteristics of plasma. When a strong current passes through an inert gas such as nitrogen, the gas will be ionized to form plasma, and at this time its temperature can rise to several thousand degrees. It has high energy utilization rate and processing efficiency, and is particularly suitable for treating fly ash after waste incineration, electronic waste, liquid or gaseous toxic and hazardous waste, etc.

[0003] In the prior art, when treating waste with a plasma furnace, the waste is usually directly put into the plasma furnace and ignited by a plasma torch to realize the incineration of the waste. Since the waste cannot be well crushed or the feed pipe cannot be dredged when the waste enters, the waste is likely to accumulate in the feed pipe during the feeding process, which is likely to cause the feed pipe to be blocked, and thus is likely to cause problems such as local overheating, which is likely to cause damage to the plasma furnace and is not conducive to ensuring the service life of the plasma furnace. Therefore, in order to solve the above problems, a multi-station device of a plasma furnace with a protection structure is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-station device of a plasma furnace with a protection structure to solve the problems mentioned in the above background technique, that is, since the waste cannot be well crushed or the feed pipe cannot be dredged when the waste enters, the waste is likely to accumulate in the feed pipe during the feeding process, which is likely to cause the feed pipe to be blocked, and thus is likely to cause problems such as local overheating, which is likely to cause damage to the plasma furnace and is not conducive to ensuring the service life of the plasma furnace.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] A multi-station device for a plasma furnace with a protection structure, including a furnace body. The furnace body includes a base 1. The inside of the base 1 is movably connected with a rotating rod 11. The top end of the rotating rod 11 is fixedly connected with a bottom plate 12. The bottom plate 12 moves inside the base 1. A first motor 13 is fixedly installed inside the base 1. One end of the rotating rod 11 away from the bottom plate 12 is fixedly connected to the output end of the first motor 13.

By putting waste into the inside of the furnace 14, high-temperature incineration of the waste can be realized through the plasma torch 18. The incinerated ash can be discharged through the slag outlet 19. The furnace 14 is arranged in three groups, which can improve the efficiency of waste treatment. At the same time, the operation of the first motor 13 drives the rotating rod 11 to rotate, so that the rotating rod 11 can drive the bottom plate 12 to rotate, and then the furnace 14 on the bottom plate 12 can be switched, which can ensure the continuity of waste incineration;

[0025] A protection mechanism is provided inside the feed pipe 15. The protection mechanism includes a feed inlet 2 which is fixedly connected to the surface of the feed pipe 15. A rotating rod 21 is movably connected inside the feed pipe 15. A second motor 22 is fixedly installed at the top of the feed pipe 15. A crushing rod 23 is fixedly connected to the surface of the rotating rod 21. A fixing rod 24 is fixedly connected to the inner wall of the feed pipe 15. A connecting block 25 is fixedly connected to the surface of the fixing rod 24. A spiral conveyor rod 26 is movably connected inside the connecting block 25. Through the setting of the spiral conveyor rod 26, it can rotate under the action of the rotating rod 21. The rotation of the spiral conveyor rod 26 can convey the waste inside the feed pipe 15, so that the waste can be stably discharged from the bottom of the feed pipe 15, thereby ensuring the stability of feeding, and avoiding unnecessary damage to the furnace 14 caused by the retention of waste in the feed pipe 15, and realizing the protection of the furnace 14.

[0026] Further, the feed inlet 2 is fixedly connected to the feed pipe 15 in two groups. The rotating rod 21 is fixedly connected to the output end of the second motor 22. The crushing rod 23 is fixedly connected to the rotating rod 21 in twenty-four groups. Through the setting of the feed inlet 2, the inside of the feed pipe 15 can be fed, facilitating the waste to enter the feed pipe 15 and be crushed by the crushing rod 23, reducing the volume of the waste and making the size of the waste more uniform, so that the waste can be better incinerated.

[0027] Further, one end of the fixing rod 24 is fixedly connected to the connecting block 25, and the other end of the fixing rod 24 is fixedly connected to the feed pipe 15. The spiral conveyor rod 26 is fixedly connected to the bottom end of the rotating rod 21.

[0028] Further, a slag discharging mechanism is provided on the surface of the furnace 14. The slag discharging mechanism includes a fixing plate 3 which is fixedly connected to the surface of the furnace 14. An activity rod 31 is movably connected inside the fixing plate 3.

A rubber block 34 is fixedly connected to the surface of the fixing block 33. A spring 35 is fixedly connected to the surface of the fixing plate 3. A rubber pad 36 is fixedly connected to the surface of the fixing block 33. Through the activity of the activity rod 31 inside the fixing plate 3 and in cooperation with the elastic property of the spring 35, the fixing block 33 can be reset after moving away from the furnace 14 and strike the furnace 14, so that the vibration generated by the strike can accelerate the discharge of the ash slag and avoid the congestion of the ash slag at the bottom of the furnace 14.

[0029] Further, one end of the spring 35 is fixedly connected to the fixed plate 3, and the other end of the spring 35 is fixedly connected to the pull plate 32. By providing the spring 35, it can play a role in resetting the pull plate 32. Furthermore, under the action of the movable rod 31 driving the pull plate 32, the fixed block 33 can be driven to reset accordingly, realizing that the fixed block 33 knocks on the furnace 14, so that the ash can be better discharged through the slag outlet 19.

[0030] Further, two groups of the rubber pads 36 are fixedly connected to one end of the fixed block 33 away from the rubber block 34. The rubber pads 36 are movably connected to the inner side of the fixed plate 3. By providing the rubber pads 36, the movement of the fixed block 33 can be limited, ensuring that the fixed block 33 can drive the rubber block 34 to move stably, and further realizing the knocking of the fixed block 33 on the furnace 14.

[0031] Working principle: During use, the waste is put into the feed pipe 15 through the feed inlet 2. The second motor 22 is electrically connected by an external power supply. The staff starts the second motor 22 by pressing the switch. The second motor 22 rotates to drive the rotating rod 21 to rotate. The crushing rod 23 can rotate accordingly under the action of the rotating rod 21 and crush the waste, which can reduce the volume of the waste. The spiral conveyor rod 26 will rotate accordingly under the action of the rotating rod 21, and then the crushed waste can be conveyed, so that the waste can be stably discharged from the bottom of the feed pipe 15, and the dredging of the feed pipe 15 can be realized;

[0032] By pulling the pull plate 32, the movable rod 31 will move inside the fixed plate 3 under the action of the pull plate 32. The fixed block 33 will drive the rubber block 34 to move accordingly under the action of the movable rod 31. At this time, the spring 35 is in a stretched state, realizing the movement of the rubber pad 36 inside the fixed plate 3. Then release the pull plate 32, and the pull plate 32 will reset under the elastic return action of the spring 35. Furthermore, the movable rod 31 drives the fixed block 33 to reset accordingly, realizing that the fixed block 33 knocks on the furnace 14. Furthermore, the vibration generated by the knocking can prevent the ash from congesting at the bottom of the furnace 14 and is more convenient for the discharge of the ash.
