Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a dust collection device for preventing dust generation in plasma treatment of hazardous waste, including a base plate 1, a furnace body 2 installed on top of the base plate 1, and a feeding system installed on top of the furnace body 2. The feeding system includes a mounting bracket 3 installed on top of the base plate 1 by multiple sets of bolts and a feeding housing 4 installed on the inner side of the mounting bracket 3 by multiple screws. A connecting pipe 5 is inserted between the bottom of the feeding housing 4 and the top of the furnace body 2. Hazardous waste inside the feeding housing 4 enters the inner side of the furnace body 2 through the connecting pipe 5. A fan 9 is installed on the lower part of the front outer wall of the feeding housing 4, and the air outlet of the fan 9 is connected to the inner side of the feeding housing 4. The fan 9 can continuously blow air backward.

[0019] Two sets of drive motors 6 are symmetrically mounted on the lower part of the front outer wall of the feed housing 4 relative to the fan 9 via motor mounts. The output ends of the drive motors 6 pass through the feed housing 4 and are coaxially connected to the rotating column 7. The two sets of drive motors 6 can control the rotating column 7 to rotate in opposite directions, thereby controlling the two sets of stirring rods 8 to rotate in opposite directions to fully agitate the hazardous waste. Multiple stirring rods 8 are evenly connected to the side wall of the rotating column 7 by multiple screws, and the two sets of stirring rods 8 are staggered. The staggered two sets of stirring rods 8 can fully agitate the hazardous waste.

[0020] The rear wall of the feeding system has a slot corresponding to the blower 9. The dust stirred up by the blower 9 will pass through the filter plate 10 and enter the connecting cylinder 11, and finally enter the inner side of the collection housing 12 for collection. The filter plate 10 is nested on the front side of the slot. The filter plate 10 can prevent hazardous waste from entering the connecting cylinder 11. The connecting cylinder 11 is inserted into the rear side of the slot, and the collection housing 12 is connected to the rear side of the connecting cylinder 11. The collection housing 12 is connected to the rear side of the mounting frame 3 by multiple screws.

[0021] Specifically, a discharge pipe 13 is inserted into the bottom of the collection housing 12, and a control valve is installed on the inside of the discharge pipe 13. Opening the control valve allows the collected dust to be discharged through the discharge pipe 13.

[0022] Furthermore, a partition 15 is provided on the upper part of the inner wall of the feed housing 4, and a rotating shaft that is movably inserted into the middle of the front and rear sides of the partition 15 is connected to the corresponding side of the feed housing 4. The partition 15 can be deflected relative to the feed housing 4. When the partition 15 is in the middle, Figure 1 It is convenient to put hazardous waste into the feed housing 4. When dust processing begins, the baffle 15 deflects as follows: Figure 2 .

[0023] Furthermore, a servo motor 14 is installed on the upper part of the front outer wall of the feed housing 4, and the output end of the servo motor 14 is coaxially connected to the front rotating shaft. The servo motor 14 can control the partition 15 to deflect by controlling the rotation of the rotating shaft.

[0024] It is worth noting that a protective frame 16 is installed on the upper part of the front outer wall of the feed housing 4, and the protective frame 16 is located outside the servo motor 14, which can provide a certain degree of protection for the servo motor 14.

[0025] It is worth noting that a flue pipe 17 is inserted into the upper part of the front side wall of the furnace body 2 to discharge the smoke and dust generated during combustion, and a discharge pipe 18 is inserted into the lower part of the front side wall of the furnace body 2 to discharge the hazardous waste after combustion.

[0026] It is worth mentioning that a reinforcing ring 19 is fixedly fitted to the bottom of the outer wall of the furnace body 2, and the reinforcing ring 19 is connected to the top of the base plate 1 by multiple screws, which can increase the stability of the furnace body 2.

[0027] Among them, the drive motor 6, fan 9, and servo motor 14 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0028] Working principle: Hazardous waste is placed inside the feed housing 4, and then the servo motor 14 controls the rotation of the rotating shaft to deflect the partition 15 to the desired position. Figure 2 Then, the two sets of drive motors 6 can control the rotating column 7 to rotate in opposite directions, so as to control the two sets of stirring rods 8 to rotate in opposite directions to fully stir the hazardous waste. At this time, the blower 9 can continuously blow air backward. The dust stirred up will pass through the filter plate 10 and enter the connecting cylinder 11 under the blowing of the blower 9, and finally enter the inner side of the collection shell 12 for collection. This can treat and collect the dust raised during feeding, and prevent dust from flying around and polluting the working environment.
