Description

Technical Field

[0001] This application relates to the technical field of waste incineration, and in particular to a high-temperature incineration apparatus for hazardous waste. Background Technology

[0002] A rotary kiln for incineration is a kiln with a refractory lining inside a cylindrical body made of steel plates. It is set slightly inclined to the horizontal and rotates slowly while transferring waste supplied from the top to the bottom. Air is supplied from the front or rear to burn the waste. Hazardous waste mainly refers to waste discharged from industrial production processes. Its harmful consequences are cumulative, delayed, and long-term. Currently, the most commonly used physical method for treating solid waste is high-temperature incineration. Generally, a feeding device for a rotary kiln for hazardous waste incineration is used to put the waste into the kiln for combustion.

[0003] Regarding the aforementioned technologies, the inventors believe that during the incineration process, the molten charge tends to accumulate at the bottom of the incinerator, resulting in incomplete combustion in various parts and affecting the incineration quality of the device. Utility Model Content

[0004] In order to improve the incineration quality of the device, this application provides a high-temperature incineration device for hazardous waste.

[0005] The high-temperature incineration device for hazardous waste provided in this application adopts the following technical solution:

[0006] A high-temperature incineration device for hazardous waste includes a rotating inner cylinder and a stirring assembly. The stirring assembly is disposed in the rotating inner cylinder and includes a rotating rod, a rotating sleeve rod, and stirring components. The rotating rod is rotatably disposed in the rotating inner cylinder along the central axis of the rotating inner cylinder. The rotating sleeve rod is rotatably sleeved on the rotating rod, and the length of the rotating sleeve rod is less than the length of the rotating rod. Several sets of stirring components are disposed on both the rotating rod and the rotating sleeve rod. Each stirring component includes a connecting rod and a stirring scraper. The connecting rod is disposed on the rotating rod and the rotating sleeve rod along the radial direction of the rotating inner cylinder. The stirring scraper is disposed at the end of the connecting rod, and the edge of the stirring scraper is fitted against the inner ring wall of the rotating inner cylinder. A driving component is disposed on the rotating inner cylinder for driving the rotating rod and the rotating sleeve rod to rotate in opposite directions.

[0007] By adopting the above technical solution, the material to be incinerated is fed into the rotating inner cylinder. The driving component drives the rotating rod and rotating sleeve rod to rotate in opposite directions. The rotating rod and rotating sleeve rod drive the stirring component installed on them to rotate in the rotating inner cylinder, stirring the material and ensuring complete combustion. Through the cooperation of the rotating inner cylinder and the stirring component, the incineration quality of the device is improved.

[0008] Optionally, a connecting outer cylinder is coaxially provided on the outside of the rotating inner cylinder, the rotating inner cylinder is provided with a plurality of connecting holes, and a gap is left between the rotating inner cylinder and the connecting outer cylinder.

[0009] By adopting the above technical solution, during material incineration, the ash produced by combustion falls into the connecting outer cylinder through the connecting hole. Sufficient combustion space is provided in the rotating inner cylinder, which helps to ensure complete combustion.

[0010] Optionally, a gas supply pipe is connected to the connecting outer cylinder, a gas supply pump is installed on the gas supply pipe, and a gas storage tank is connected to the end of the gas supply pipe away from the connecting outer cylinder.

[0011] By adopting the above technical solution, during incineration, the combustion-supporting gas in the gas storage tank is fed into the connecting outer cylinder under the action of the gas pump, reducing the possibility that the material cannot be fully burned.

[0012] Optionally, a connecting pipe is provided at the bottom end of the connecting outer cylinder, and a transmission pipe is connected at the bottom end of the connecting pipe. A transmission screw is rotatably arranged in the transmission pipe along its length direction. A collection box is connected at the end of the transmission pipe away from the connecting pipe.

[0013] By adopting the above technical solution, the ash produced by combustion falls into the transmission pipe and is transported to the collection box for temporary storage by the transmission screw.

[0014] Optionally, the mixing assembly further includes a connecting strip connected to the connecting rod. The connecting strip has a connecting groove at one end away from the connecting rod. One side of the mixing scraper is slidably disposed in the connecting groove. An elastic element is disposed in the connecting groove, and the two ends of the elastic element are respectively connected to the mixing scraper and the inner bottom wall of the connecting groove.

[0015] By adopting the above technical solution, the elastic element enables a sliding connection between the stirring scraper and the connecting rod. This reduces the possibility of the stirring scraper damaging the inner wall of the rotating inner cylinder when material adheres to it.

[0016] Optionally, a stirring frame is connected to the connecting strip, and a gap is left between the side of the stirring frame and the inner ring wall of the rotating inner cylinder, and the stirring scraper is fitted to one side of the stirring frame.

[0017] By adopting the above technical solution, when the stirring scraper slides in the connecting groove, the stirring frame and the stirring scraper slide relative to each other, and the stirring frame scrapes off the material adhering to one side of the stirring scraper.

[0018] Optionally, the rotating inner cylinder is rotatably connected to the connecting outer cylinder, a cleaning brush is provided on the inner ring wall of the connecting outer cylinder, one side of the cleaning brush is fitted against the outer ring wall of the rotating inner cylinder, and a driving component for driving the rotating inner cylinder to rotate is provided on the connecting outer cylinder.

[0019] By adopting the above technical solution, the rotating inner cylinder rotates in the connecting outer cylinder under the driving action of the driving component. The cleaning brush cleans the outer ring wall of the rotating inner cylinder and scrapes off the ash attached to it, thus achieving the cleaning of the rotating inner cylinder.

[0020] Optionally, one end of the rotating inner cylinder is detachably provided with an inner cylinder cover, and one end of the connecting outer cylinder is detachably provided with an outer cylinder cover.

[0021] By adopting the above technical solution, the outer cylinder cover and inner cylinder cover are designed to facilitate users to remove them and clean the connecting outer cylinder and rotating inner cylinder.

[0023] 1. The rotation of the inner cylinder and the coordination of the stirring components improve the combustion quality of the device;

[0024] 2. The elastic element design enables a sliding connection between the stirring scraper and the connecting rod. This reduces the possibility of the stirring scraper damaging the inner wall of the rotating inner cylinder when material adheres to it.
