It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 6 shown, the present invention provides a technical solution: a comprehensive utilization and treatment equipment for petrochemical sludge, including a combustion component 1. A feeding component 2 is arranged on the top of the combustion component 1, and a cleaning component 3 is arranged inside the combustion component 1. The combustion component 1 includes a combustion furnace 101 and a furnace cover 105. The cleaning component 3 includes a connecting ring 301. An installation ring 302 is installed on the outer side of the bottom of the connecting ring 301. A scraper 303 is installed at the bottom of the installation ring 302. Cylinders 304 are symmetrically installed on the top of the connecting ring 301. Buckle plates 305 are installed on the outer sides of the connecting ring 301 and the installation ring 302. A limit rod 306 penetrates through the inside of the buckle plate 305. One end of the limit rod 306 penetrates through a fixed rod 307. The side surface of the scraper 303 is connected to the inner side of the combustion furnace 101.

[0024] In this embodiment, after the combustion of petrochemical sludge is completed inside the combustion furnace 101, the cylinder 304 extends to push the connecting ring 301 downward, causing the scraper 303 to scrape the inner wall of the combustion furnace 101, effectively cleaning the impurities and furnace ash adhering to the inner wall of the combustion furnace 101, avoiding the influence of dust impurities on heat transfer, enabling heat to be effectively transferred to the petrochemical sludge, improving the combustion efficiency, and at the same time reducing local overheating or uneven temperature caused by furnace ash accumulation, improving the uniformity and effect of combustion. The installation ring 302 is clamped on the outside of the connecting ring 301, and then the buckle plate 305 is used to fix the connecting ring 301 and the installation ring 302. Finally, the limiting rod 306 is beneficial for limiting, facilitating the maintenance and replacement of the scraper 303, improving the cleaning effect, being convenient and fast in operation, beneficial to improving the installation and disassembly efficiency, and the fixing rod 307 is beneficial for providing a limiting function for the limiting rod 306.

[0025] Embodiment 2: As Figures 1 - 6 shown, the feeding assembly 2 includes a feeding port 201. A rotating shaft 203 is installed inside the feeding port 201. A motor 202 is installed at the top of the rotating shaft 203. A auger 204 is installed on the outside of the rotating shaft 203. A fixing frame 205 is installed at the top of the motor 202. One end of the fixing frame 205 is connected to the side surface of the feeding port 201. An air inlet 102 is connected to the side surface of the combustion furnace 101. A smoke exhaust pipe 104 is connected to the top of the furnace cover 105. A discharge pipe 106 is connected to the bottom of the combustion furnace 101. A support frame 103 is installed on the outside of the combustion furnace 101.

[0026] In this embodiment, the air inlet 102 facilitates the entry of air into the combustion furnace 101, ensuring sufficient oxygen inside the combustion furnace 101 and promoting combustion. When feeding petrochemical sludge, the motor 202 is electrically driven to rotate the rotating shaft 203, which in turn drives the auger 204 to rotate. The auger 204 is beneficial for conveying the petrochemical sludge, enabling the petrochemical sludge to be evenly sprayed into the combustion furnace 101 through the nozzle at the bottom of the feeding port 201, avoiding the accumulation and blockage of sludge, ensuring the continuity of feeding, shortening the feeding time, and thus improving the working efficiency. The rotation of the auger 204 continuously conveys and extrudes the input sludge, causing the petrochemical sludge to be ejected from the bottom of the nozzle at the bottom of the feeding port 201, enabling the petrochemical sludge to be efficiently sprayed inside the combustion furnace 101, achieving efficient combustion, and being beneficial to improving the combustion efficiency of the petrochemical sludge. The smoke exhaust pipe 104 facilitates the discharge of flue gas during the combustion process, and the support frame 103 is beneficial for ensuring the stability of the combustion furnace 101.

[0027] Working principle of this embodiment: During use, first connect to the petrochemical sludge pipeline so that the pipeline is connected to the feed inlet 201. At the same time, the motor 202 drives the rotating shaft 203 to rotate electrically, thereby driving the auger 204 to rotate. The auger 204 is beneficial for transporting the petrochemical sludge and enabling the petrochemical sludge to enter the combustion furnace 101 evenly. The air inlet 102 facilitates the entry of air into the combustion furnace 101 and cooperates with the combustion furnace 101 to burn the petrochemical sludge. The burned sludge is discharged through the discharge pipe 106. When the combustion of the petrochemical sludge inside the combustion furnace 101 is completed, the cylinder 304 extends to push the connecting ring 301 downward, causing the scraper 303 to scrape the inner wall of the combustion furnace 101, effectively cleaning the impurities and furnace ash remaining and adhered to the inner wall of the combustion furnace 101. The mounting ring 302 is clamped on the outside of the connecting ring 301, and then the buckle plate 305 is used to fix the connecting ring 301 and the mounting ring 302. Finally, the limiting rod 306 is beneficial for limiting, facilitating the maintenance and replacement of the scraper 303.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
