Specifically, in this embodiment, the upper side wall of the discharge end of the screw conveyor 8 is a cage structure, the gas outlet end 702 of the furnace body 7 is connected with the steam drum 15, and the wall cleaning device is arranged in the furnace body 7. The wall cleaning device includes a first frame, a supporting beam 3, a second frame and at least one scraper 4 for scraping off attachments on the inner wall of the furnace body 7, and the first frame 701 is used to scrape off attachments on the inner wall of the furnace body 7. There are multiple frames, and multiple first frames are arranged along the axial direction of the furnace body 7. The first frame includes a sleeve 1 and multiple first connecting columns 2. The sleeve 1 coincides with the axis of the furnace body 7. The multiple first connecting columns 2 are evenly arranged along the circumference of the sleeve 1. The first end of each first connecting column 2 is fixedly connected to the outer wall of the sleeve 1, and the second end of each first connecting column 2 is fixedly connected to the inner wall of the furnace body 7. Each sleeve 1 can be rotatably sleeved on the supporting beam 3. The second frame is fixedly connected to the supporting beam 3, and the scraper 4 is fixedly connected to the second frame. A plurality of guide plates 16 are arranged on the scraper 4 along the length direction of the scraper 4 (the length direction of the scraper 4 is the same as that of the first connecting column 2). The guide plate 16 is used to guide the residue produced by the cracking inside the furnace body 7 to the feed end 701 of the furnace body 7. The feed end 701 of the furnace body 7 is circumferentially provided with a plurality of guide plates, and each guide plate is fixedly connected to the inner wall of the furnace body 7; a condensation system for condensing the waste gas produced by the cracking; a waste gas recovery device for recovering the waste gas; a dust removal device, the steam drum 15, the condensation system, the waste gas recovery device, the furnace 13 and the dust removal device are connected in sequence; a conveying device, the slag discharge pipeline 10 is connected to the conveying device, and the conveying device is used to transport the residue discharged from the slag discharge pipeline 10 to a specific position (depending on actual needs). Specifically in this embodiment, the first valve 11 and the second valve 12 are both ball valves. The guide plate 16 has a certain diversion angle to guide the residue produced by the cracking inside the furnace body 7 to the feed end 701 of the furnace body 7.

[0029] During specific use, the first valve 11 is opened, and the oil sludge enters the screw conveyor 8 from the feed pipeline 9. The screw conveyor 8 rotates forward to continuously convey the oil sludge to the furnace body 7. After a certain amount of oil sludge is conveyed, the first valve 11 is closed, and the furnace 13 works to heat the furnace body 7. At the same time, the furnace body 7 rotates forward to stir the oil sludge. As the temperature of the furnace body 7 increases, the oil sludge is cracked. After a certain period of time, the oil sludge is cracked, the furnace 13 stops heating, and the furnace body 7 stops rotating. The gas generated during the cracking process is discharged through the gas outlet 702 of the furnace body 7, and the residue remains in the furnace body 7. When slag discharge is required, the second valve 12 is opened, and the screw conveyor 8 and the furnace body 7 are reversed. As the furnace body 7 rotates, the residue remaining in the furnace body 7 is collected at the feed end 701 of the furnace body 7 under the action of the guide plate 16. At the same time, the guide plate continuously stirs up the residue, and when the residue falls, it just falls into the slag dropping hole. The residue falling into the slag dropping hole is conveyed by the screw conveyor 8 to the slag discharge pipeline 10, and finally discharged through the slag discharge pipeline 10. The feeding and slag discharge of this fully automatic sequential sludge processing equipment are fully automated, and no manual participation is required, which effectively saves manpower.

[0030] In addition, during the specific use, the scraper 4 has a certain weight and will only hang down under the action of gravity. The furnace body 7 rotates while the scraper 4 remains in a hanging state, which is equivalent to constantly scraping the inner wall of the furnace body 7, thereby playing a wall cleaning role. The wall cleaning device can automatically clean the inner wall of the furnace body 7 under the action of gravity, further saving manpower, and the inner wall of the furnace body 7 is cleaned conveniently and quickly.

[0031] In this embodiment, if Figure 4 As shown, specifically, the number of scrapers 4 is two, and correspondingly, the second frame includes two second connecting columns 5 and an intermediate connecting column 6, the first ends of the two second connecting columns 5 are fixedly connected, and the first ends of the two second connecting columns 5 are both fixedly connected to the supporting beam 3, the two scrapers 4 are respectively fixedly connected to the second ends of the two second connecting columns 5, the first end and the second end of the intermediate connecting column 6 are respectively fixedly connected to the two second connecting columns 5, and the two second connecting columns 5 and the intermediate connecting column 6 are arranged in an A shape.

When one scraper 4 is provided, the three second frames are fixedly connected to the scraper 4, and when multiple scrapers 4 are provided, each scraper 4 is fixedly connected to the three second frames.

[0033] In this embodiment, if Figure 1As shown, the condensation system includes a plurality of groups of tube and shell condenser groups connected in sequence, and the tube and shell condenser group includes two tube and shell condensers 17 arranged in parallel. In this embodiment, the number of tube and shell condenser groups is specifically 3. The purpose of the tube and shell condenser group including two tube and shell condensers 17 arranged in parallel is to prevent the situation that only one tube and shell condenser 17 is set, and the tube and shell condenser 17 is damaged and the device cannot work. When two tube and shell condensers 17 are connected in parallel, when one of the tube and shell condensers 17 is damaged, the other tube and shell condenser 17 is not affected, and the device can continue to work. The function of the condensation system is to separate the oil and gas in the exhaust gas. During specific use, the tube and shell condenser 17 is connected to the oil tank 21, and the gaseous oil product is cooled down and liquefied into liquid oil product when passing through the tube and shell condenser 17, and is stored in the oil tank 21.

[0037] In this embodiment, the scraper 4 is an arc-shaped scraper 4, and the outer side wall of the scraper 4 is in contact with the inner side wall of the furnace body 7. It should be noted that the shape of the scraper 4 is not limited to the arc-shaped, and other shapes can be selected as long as it can scrape off the attached objects on the inner wall of the furnace body 7. For example, the scraper 4 can also be a straight plate structure. In addition, in order to facilitate the scraping of the attached objects on the inner wall of the cracking furnace, the scraper 4 can also be tilted at a certain angle or a scraper can be set on the scraper 4.

[0038] In this embodiment, specifically, the number of the first frames is two.
