Description

Technical Field

[0001] This utility model relates to the field of denitrification equipment technology, and in particular to a conveying device for a special vehicle for denitrification urea. Background Technology

[0002] Urea, also known as urea or carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystalline solid primarily used in denitrification reactions and has wide applications in medicine, agriculture, and industry. In denitrification processes, urea, as a commonly used denitrification agent, needs to be transported by specialized vehicles and conveyed to the denitrification equipment via a screw conveyor.

[0003] Because urea generates moisture during storage, some urea particles adhere to the inner wall of the conveying pipeline, resulting in the material not being completely discharged. This not only wastes resources but also causes corrosion of the inner wall of the conveying pipeline. In view of the above reasons, this application proposes a conveying device for a special vehicle for denitrification urea. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a conveying device for a special vehicle for denitrification urea.

[0005] The technical solution of this utility model: a conveying device for a special vehicle for denitrification urea, including a conveying pipe, a drive motor fixedly mounted on one side of the conveying pipe, a rotating shaft fixedly mounted on the output end of the drive motor, the rotating shaft being movably connected to the inner wall of the conveying pipe, and one end of the rotating shaft penetrating one side of the inner wall of the conveying pipe, a spiral conveying blade for conveying being fixedly mounted on the rotating shaft, a plurality of scrapers being fixedly mounted on the rotating shaft, and a striking structure being provided at the top of the conveying pipe;

[0006] The striking structure includes a first pulley and a second pulley for transmission and a mounting base for installation. A guide rod is movably disposed within the mounting base, and a striking block is fixedly disposed at one end of the guide rod. A second rotating shaft is fixedly disposed at the center of the second pulley, and multiple cams are fixedly disposed on the second rotating shaft.

[0007] Optionally, the first pulley is fixedly sleeved on one end of the first rotating shaft, the first pulley and the second pulley are fitted with the same belt, and the second rotating shaft is movably provided with two upright plates, which are fixedly connected to the top of the conveying pipe.

[0008] Optionally, both upright plates are provided with round holes, and bearings are fixedly installed in both round holes. The inner rings of both bearings are fixedly sleeved on the rotating shaft.

[0009] Optionally, the striking block is made of metal and is covered with a rubber layer.

[0010] Optionally, each of the multiple scrapers is fixedly provided with a connecting rod on the side near the rotating shaft, and the end of each of the multiple connecting rods away from the scraper is fixedly connected to the rotating shaft. The outer surface of the scraper is coated with a corrosion-resistant layer.

[0011] Optionally, two mounting brackets are fixedly provided at the bottom of the conveying pipe, a storage tank is fixedly provided at the top of the conveying pipe, and a discharge port and a guide hopper are provided at one end of the conveying pipe, with the guide hopper located below the discharge port.

[0012] Optionally, the inner wall of the conveying pipe is provided with a flushing assembly, which includes multiple annular pipes for spraying water. The annular pipes are fixedly connected to the inner wall of the conveying pipe. Water guide pipes are fixedly provided on the outside of the multiple annular pipes. One end of each of the multiple water guide pipes passes through the conveying pipe and is fixedly provided with the same horizontal pipe. A water inlet connector is fixedly provided on the horizontal pipe.

[0013] Optionally, two connecting plates are fixedly provided on the outside of the annular pipe, and the connecting plates are fixedly connected to the inner wall of the conveying pipe. The annular pipe is provided with multiple water spray holes.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This invention, through the arrangement of a scraper, a first pulley, a second pulley, a cam, and a striking block, allows the equipment to drive the scraper via a connecting rod during material conveying. The scraper can scrape off the material adhering to the inner wall of the conveying pipe. The combined use of the two pulleys allows the cam to intermittently squeeze the guide rod, which in turn drives the striking block to strike the conveying pipe. The resulting vibration can separate the material not scraped off by the scraper from the inner wall of the conveying pipe, thereby optimizing the material discharge effect of the equipment, saving resources, and reducing the probability of corrosion of the inner wall of the conveying pipe.

[0016] Furthermore, by setting up annular pipes, horizontal pipes, water guide pipes, and water inlet connectors, when the delivery pipe needs to be cleaned, the water injection pipe is connected to the water inlet connector, and water enters the water guide pipe through the horizontal pipe. The water in the water guide pipe then enters the annular pipe, and finally sprays out through the spray holes to act on the inner wall of the delivery pipe, achieving the purpose of cleaning. The setting of multiple annular pipes can improve the cleaning effect and speed up the cleaning process. Attached Figure Description

[0038] Example 1

[0039] like Figures 1-3 As shown, the present invention proposes a conveying device for a special vehicle for denitrification urea, including a conveying pipe 1, a drive motor 3 fixedly mounted on one side of the conveying pipe 1, a rotating shaft 4 fixedly mounted on the output end of the drive motor 3, the rotating shaft 4 being movably connected to the inner wall of the conveying pipe 1, and one end of the rotating shaft 4 penetrating one side of the inner wall of the conveying pipe 1, a spiral conveying blade 5 for conveying being fixedly mounted on the rotating shaft 4, and multiple scrapers 7 fixedly mounted on the rotating shaft 4, the scrapers 7 being able to scrape off the attached material, a connecting rod 6 fixedly mounted on the side of the multiple scrapers 7 near the rotating shaft 4, the ends of the multiple connecting rods 6 away from the scrapers 7 being fixedly connected to the rotating shaft 4, the outer surface of the scrapers 7 being coated with a corrosion-resistant layer, a striking structure 8 being provided at the top of the conveying pipe 1, two mounting brackets 2 being fixedly mounted at the bottom of the conveying pipe 1, a storage tank 10 being fixedly mounted at the top of the conveying pipe 1, and a discharge port and a guide hopper 11 being provided at one end of the conveying pipe 1, the guide hopper 11 being located below the discharge port;

[0040] like Figure 3As shown, the striking structure 8 includes a first pulley 801 and a second pulley 802 for transmission, and a mounting base 806 for installation. The first pulley 801 is fixedly sleeved on one end of the first shaft 4. The same belt is sleeved on the first pulley 801 and the second pulley 802. A guide rod 807 is movably installed inside the mounting base 806. A striking block 808 is fixedly installed at one end of the guide rod 807. The striking block 808 is made of metal and is covered with a rubber layer. The rubber layer can prevent the outside of the conveying pipe 1 from being damaged by impact. A second shaft 803 is fixedly installed at the center of the second pulley 802. Two upright plates 804 are movably installed on the outside of the second shaft 803. Both upright plates 804 have round holes. Bearings are fixedly installed in both round holes. The inner rings of the two bearings are fixedly sleeved on the second shaft 803. The two upright plates 804 are fixedly connected to the top of the conveying pipe 1. Multiple cams 805 are fixedly installed on the second shaft 803.

[0041] In this embodiment, during material conveying, the drive motor 3 drives the rotating shaft 4, which in turn drives the connecting rod 6 and the pulley 801. The connecting rod 6 drives the scraper 7, which is in contact with the inner wall of the conveying pipe 1. This scrapes off the material adhering to the inner wall of the conveying pipe 1. The pulley 801 drives the pulley 802, which in turn drives the rotating shaft 803. The rotating shaft 803 then drives multiple cams 805. When the protrusion of the cam 805 contacts the guide rod 807, the guide rod 807 drives the striking block 808 at one end to lift it up. When the protrusion of the cam 805 separates from the guide rod 807, the striking block 808 hammers the surface of the conveying pipe 1. The resulting vibration separates the material not scraped off by the scraper 7 from the inner wall of the conveying pipe 1, thereby optimizing the material discharge effect of the equipment, saving resources, and reducing the probability of corrosion of the inner wall of the conveying pipe 1.

Multiple water spray holes 903 are provided on the annular pipes 901. The connecting plates 902 are fixedly connected to the inner wall of the conveying pipe 1. Water guide pipes 904 are fixedly provided on the outside of each of the multiple annular pipes 901. One end of each pipe 904 passes through the conveying pipe 1 and is fixedly provided with the same horizontal pipe 905. A water inlet connector 906 is fixedly provided on the horizontal pipe 905. When the conveying pipe 1 needs to be cleaned later, the water injection pipe is connected to the water inlet connector 906. Water enters the water guide pipe 904 through the horizontal pipe 905. The water in the water guide pipe 904 then enters the annular pipe 901 and is finally sprayed out through the spray hole 903 to act on the inner wall of the conveying pipe 1, so as to achieve the purpose of cleaning. The setting of multiple annular pipes 901 can improve the cleaning effect and speed up the cleaning process.

[0044] The above specific embodiments are merely several optional embodiments of this utility model.
