Embodiment 1

[0031] Hazardous waste rotary kiln incineration online decoking device, basically as attached figure 1 As shown, the installation frame is included, and the bottom of the installation frame is provided with moving wheels, which can realize the movement of the installation frame. The baffle plate 1 that can close the discharge port of the rotary kiln 9 is fixed on the mounting frame, that is, when the baffle plate 1 is offset against the discharge port end of the rotary kiln 9, the discharge port is closed; The outlet 11 connected to the bottom of the feed port can export the incinerated hazardous waste powder.

[0032] It also includes a decoking shaft 2 that runs through the upper part of the baffle plate 1 and is rotatably connected with the baffle plate 1. The part of the decoking shaft 2 located on the left side of the baffle plate 1 is provided with a spiral coke scraping knife 21; a motor is also fixed on the mounting frame, and the motor It is coaxially fixed with the ...

Embodiment 2

[0045] Embodiment 2 differs from Embodiment 1 only in that, as figure 2 As shown, in this embodiment, the drive member includes a drive shaft 7 and a transmission shaft 8 arranged perpendicular to the paper surface, both of which are rotatably connected to the mounting bracket, and the drive shaft 7 is located above the material guide shaft 4 , The transmission shaft 8 is located below the material guide shaft 4 . A driving bevel gear 42 is coaxially fixed on the material guide shaft 4 , and a driven bevel gear 71 meshing with the driving bevel gear 42 is coaxially fixed on the driving shaft 7 . Drive shaft 7 is also coaxially fixed with drive gear 72 , drive gear 72 is an incomplete gear, and coaxially fixed with drive shaft 8 is driven gear 81 that can mesh with drive gear 72 . A connecting rod 82 is also fixed on the transmission shaft 8, and a counterweight 821 is fixed on the end of the connecting rod 82 away from the transmission shaft 8, and the counterweight 821 can ...

Abstract

The invention belongs to the technical field of auxiliary equipment for hazardous waste incineration, and discloses a hazardous waste rotary kiln incineration online decoking device. The device comprises a mounting frame, wherein a decoking shaft is rotationally connected to the mounting frame, and a spiral coke scraper is coaxially arranged on the decoking shaft; a receiving plate is also fixed to the mounting frame and is located below the decoking shaft; and the upper surface of the receiving plate inclines downwards in the direction away from the mounting frame. The problems that at present, during decoking, a rotary kiln needs to be shut down, the hazardous waste treatment time is long, and the treatment efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for hazardous waste incineration, and in particular relates to an online decoking device for hazardous waste rotary kiln incineration. Background technique [0002] Hazardous waste is the abbreviation of hazardous waste, which refers to waste that is included in the national hazardous waste list or identified according to the national hazardous waste identification standards and identification methods with hazardous waste characteristics. Most hazardous wastes contain toxic and harmful substances, which will pollute the environment if they are discharged randomly, so they usually need to be treated before they are discharged. At present, rotary kilns are usually used to incinerate hazardous waste, and then the ash after incineration is discharged. [0003] During the operation of the rotary kiln, it needs to be continuously rotated and kept at a high temperature, so that the objects i...
