Description

Technical Field

[0001] The utility model relates to the technical field of diesel hydrogenation production, in particular to a diesel hydrogenation refining device. Background Technique

[0002] Hydrogenated diesel is mainly high-quality diesel produced by the chemical reaction of hydrogen and sulfur in diesel to form hydrogen sulfide. Diesel is a product obtained after atmospheric fractional distillation of petroleum. If directly refined from petroleum, the contents of sulfur, nitrogen, and oxygen in diesel are relatively high, and the content of olefins is also relatively high. A high content of olefins in the product is likely to cause discoloration, and it will also affect the service life of motor vehicles and cause relatively greater air pollution. To overcome these problems and improve the performance of diesel, a hydrogenation process is generally introduced during the processing of diesel. On the one hand, it can reduce the contents of sulfur, nitrogen, oxygen, and olefins in diesel and improve the stability of the product; on the other hand, it can also reduce the impact of the product on the atmosphere. Therefore, everything is for environmental protection. Generally, a catalyst needs to be added during petroleum hydrogenation. However, in the current hydrogenation refining devices on the market, it is not easy to control the amount of catalyst added by manual judgment during the catalyst addition process. For this reason, a diesel hydrogenation refining device is now proposed. Content of the Utility Model

A feeding conversion device 300 is fixedly installed inside the refining device main body 100. An inclined hopper 301 is fixedly connected to the top of the feeding conversion device 300. A bottom plate 302 is fixedly installed at the lower end of the inclined hopper 301. A rotating semi-circular block 303 is rotatably connected below the inclined hopper 301. A rotating rod 304 is fixedly connected to the outside of the rotating semi-circular block 303. A rotating bearing 305 is rotatably connected to the outside of the rotating semi-circular block 303. An outer ring 306 is fixedly connected to the outside of the rotating bearing 305.

[0022] According to the above technical solution, the feeding conversion device 300 discharges materials through the lower discharge port 201. The discharge port 201 is fixed. Regarding the control of the discharge time, after discharging, it enters the feeding conversion device 300. At this time, the rotating semi-circular block 303 is driven to rotate by the rotating rod 304, thereby changing the outlet below the inclined hopper 301.

[0023] Specifically, a toothed rod 400 is slidably connected to the right wall of the feeding conversion device 300. The toothed rod 400 is in toothed connection with the rotating rod 304.

[0024] According to the above technical solution, when the toothed rod 400 moves, it drives the rotating rod 304 to rotate through the teeth. Thus, when the rotating rod 304 rotates, it drives the rotating semi-circular block 303 to rotate together. When the rotating semi-circular block 303 rotates, it changes the discharge diameter, thereby controlling the amount of catalyst added.

[0025] Specifically, a threaded column 500 is threadedly connected through the right wall of the refining device main body 100. A threaded sleeve is fixedly installed at the connection between the threaded column 500 and the refining device main body 100.

[0026] According to the above technical solution, when the threaded column 500 rotates, it will move to the left through the threaded sleeve and drive the rotating rod 304 to rotate through the teeth.

[0027] Specifically, a driving device 600 is fixedly installed outside the right side of the refining device main body 100. A stirring shaft 601 is rotatably connected to the lower part of the refining device main body 100, and a stirring rod 602 is fixedly connected to the outside of the stirring shaft 601.

[0028] According to the above technical solution, the driving device 600 drives the stirring shaft 601 to rotate, thereby stirring the raw materials after adding the catalyst and accelerating the reaction process.

[0029] Specifically, a positioning plate is slidably connected to the outside of the tooth rod 400, and a return spring 401 is fixedly connected to the positioning plate.

[0030] According to the above technical solution, the return spring 401 is used for the return of the tooth rod 400 after moving.

[0031] Specifically, a fixing plate 307 is fixedly installed in the middle of the refining device main body 100. A leakage hole 308 is provided on the fixing plate 307, and the fixing plate 307 is fixedly connected to the feeding conversion device 300.

[0032] According to the above technical solution, the catalyst falling from the inclined hopper 301 will be added to the reaction chamber at the lower part of the refining device main body 100 through the leakage hole 308, so as to carry out the reaction.

[0033] During use, rotate the threaded column 500. When the threaded column 500 rotates, it will move to the left through the threaded sleeve and squeeze the tooth rod 400 to move. When the tooth rod 400 moves, it drives the rotating rod 304 to rotate through the teeth, so that the rotating rod 304 drives the rotating semi-circular block 303 to rotate together when rotating. When the rotating semi-circular block 303 rotates, it further changes the outlet diameter of the material, thereby controlling the amount of catalyst added. The feeding conversion device 300 discharges the material through the lower discharge port 201. The discharge port 201 is fixed. The key lies in the control of the discharge time. After discharging, it enters the feeding conversion device 300. At this time, the rotating semi-circular block 303 is driven by the rotating rod 304 to rotate, thereby changing the outlet below the inclined hopper 301 and controlling the amount of catalyst added; a positioning plate is slidably connected to the outside of the tooth rod 400, and a return spring 401 is fixedly connected to the positioning plate. The return spring 401 is used for the return of the tooth rod 400 after moving, thereby improving the practicability of the device and enabling it to operate without obstacles.
