Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment, and in particular to a scraper conveying device. Background Technology
[0002] During sludge drying, to ensure sufficient contact between the sludge and the high-temperature air inside the drying chamber, the sludge usually needs to be divided into equal portions. This ensures that as much sludge as possible remains in contact with the hot air within the drying device. Furthermore, to maintain consistent dryness, the sludge needs to enter the drying device evenly. However, existing scraper conveyor systems often result in sludge falling into the drying device in clumps, with each clump having an inconsistent volume. This leads to uneven drying levels, requiring multiple drying cycles and impacting subsequent sludge processing. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a scraper conveying device.
[0004] This utility model is achieved by the following technical solution: a scraper conveying device, including a housing, a conveyor chain plate driven by a drive unit is provided inside the housing, a scraping component is provided on the conveyor chain plate, the scraping component includes a linkage unit and a scraping part, the linkage unit is connected to the drive unit of the conveyor chain plate, the scraping part is disposed on the linkage unit and driven by the linkage unit, and the end of the scraping part is driven by the linkage unit to abut against the conveyor chain plate.
[0005] The leveling part includes a scraper, which is driven by the linkage part and is positioned above the conveyor chain plate and moves back and forth along the height direction of the outer shell.
[0006] The linkage part includes a linkage rod and a linkage wheel. A sliding groove is formed on the inner wall of the outer shell. A limiting block is provided on the side wall of the scraper. The limiting block is engaged in the sliding groove. The sliding groove is arranged along the height direction of the outer shell. The outer shell is driven by the linkage part to slide back and forth along the sliding groove.
[0007] The linkage wheel is driven to rotate by the drive unit. One end of the linkage rod is rotatably connected to the disc surface of the linkage wheel. A moving groove is opened on the scraper. A moving block is engaged in the moving groove and the moving block slides back and forth in the moving groove. The other end of the linkage rod is rotatably connected to the moving block.
[0008] The conveyor chain plate includes several conveyor plates connected by pins. Adjacent conveyor plates rotate around the pins. Several support shafts are provided below the conveyor chain plate. Support sprockets are sleeved on the support shafts. The teeth of the support sprockets engage with the conveyor chain plate. The forward movement of the conveyor chain plate drives the support sprockets to rotate.
[0009] The drive unit includes a drive sprocket and a drive motor. The drive motor drives the drive sprocket to rotate. The conveyor chain plate is wound around the drive sprocket and meshes with the drive sprocket. The rotation of the drive sprocket causes the conveyor chain plate to move.
[0010] Compared to existing technologies, this invention utilizes a scraper conveyor to transport sludge, allowing it to be used in conjunction with a sludge drying device. Specifically, the scraper conveyor ensures the sludge delivered to the drying device has a uniform thickness by using a leveling section during transport. Although the sludge initially appears as clumps on the conveyor chain, the scraper presses it down, causing it to fall into the drying device in flake form. This results in more uniform feeding, more thorough drying, and easier subsequent processing. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0015] Reference Figure 1 and Figure 2A scraper conveying device 311 includes a housing 1, inside which is a conveyor chain 2 driven by a drive unit 21. A leveling component 3 is mounted on the conveyor chain 2, comprising a linkage unit 32 and a leveling part 31. The linkage unit 32 is connected to the drive unit 21 of the conveyor chain 2, and the leveling part 31 is mounted on the linkage unit 32 and driven by it. When sludge is placed on the conveyor chain 2, the movement of the conveyor chain 2 drives the leveling part 31 to flatten the sludge, causing it to fall into the drying device in sheet form. This results in the sludge being dried more evenly and thoroughly in the drying device, reducing the pressure on subsequent processing and improving the efficiency of sludge drying.
[0016] The end of the leveling part 31 abuts against the conveyor chain plate 2 under the drive of the linkage part 32, flattening the sludge into a clump. In this embodiment, the leveling part 31 includes a scraper 311, which is driven by the linkage part 32 and is positioned above the conveyor chain plate 2, reciprocating along the height direction of the outer shell 1. In this embodiment, the linkage part 32 includes a linkage rod 321 and a linkage wheel 322. A sliding groove 323 is formed on the inner wall of the outer shell 1, and a limiting block is provided on the side wall of the scraper 311. The limiting block is engaged in the sliding groove 323. The sliding groove 323 is arranged along the height direction of the outer shell 1, and the outer shell 1 slides back and forth along the sliding groove 323 driven by the linkage part 32. The linkage wheel 322 is driven to rotate by the drive unit 21. One end of the linkage rod 321 is rotatably connected to the disc surface of the linkage wheel 322. A moving groove 324 is formed on the scraper 311. A moving block 325 is engaged in the moving groove 324 and slides back and forth within the moving groove 324. The other end of the linkage rod 321 is rotatably connected to the moving block 325. In this embodiment, the drive unit 21 includes a drive sprocket 211 and a drive motor 24. The drive motor 24 drives the drive sprocket 211 to rotate. The conveyor chain plate 2 is wound around the drive sprocket 211 and meshes with the drive sprocket 211. The rotation of the drive sprocket 211 causes the conveyor chain plate 2 to move. The linkage wheel 322 can be sleeved on the shaft of the drive sprocket 211 and can rotate coaxially with the drive wheel. Thus, the rotation of the drive sprocket 211 can drive the linkage wheel 322 to rotate, so that the scraper 311 can repeatedly squeeze during the conveying process. Although the sludge is placed in a clump on the conveyor chain plate 2 when it is fed, after being pressed by the scraper 311, the sludge finally falls into the drying device in a sheet shape. The feeding of the drying device is more uniform, and the sludge is dried more thoroughly, which is convenient for subsequent processing.
[0017] In this embodiment, the conveyor chain plate 2 includes several conveyor plates 22, which are connected by pins 23. Adjacent conveyor plates 22 rotate around the pins 23. Several support shafts 212 are provided below the conveyor chain plate 2. Support sprockets 213 are sleeved on the support shafts 212. The teeth of the support sprockets 213 are engaged with the conveyor chain plate 2. The conveyor chain plate 2 moves forward, driving the support sprockets 213 to rotate.
[0018] Compared to existing technologies, this invention allows the scraper 311 conveying device to be used in conjunction with a sludge drying device when conveying sludge. Specifically, to ensure the sludge delivered to the drying device has a uniform thickness, the scraper 311 leveling section is used during the conveying process. Although the sludge initially forms clumps on the conveyor chain 2, the scraper 311 presses it down, causing it to eventually fall into the drying device in flake form, resulting in more thorough drying and facilitating subsequent processing.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
