Technical Field

[0001] The utility model relates to the technical field of belt conveying, in particular to a horizontal belt return sludge scraping device. Background Technique

[0002] In the sludge project, the horizontal belt is used to convey the dried sludge. The sludge is conveyed by the horizontal belt (primary belt) to the sub-belt conveyor (secondary belt), and the sub-belt conveyor then conveys it to the inclined belt. When the horizontal belt conveys the sludge, due to the long belt (the east-west length is 68m), when the belt returns, there is a lot of sludge remaining on the belt surface. The sludge adhered to the belt surface is easy to spill along the way, causing serious ground pollution. Therefore, we propose a horizontal belt return sludge scraping device.

Slide holes are provided on both corresponding side walls of the communicating groove 11, and slide rods 12 are slidably connected in the slide holes in a matching manner. The slide rods 12 are fixedly connected to the inside of the sliding plate 16. A fixing hole 15 is provided on the surface of the connection block 8 between the two connection grooves 9. One end of the slide rod 12 located on the sliding plate 16 slides through the column 5 and is clamped in the fixing hole 15. The other end of the slide rod 12 passes through the column 5 and is fixedly connected to a pulling plate 14. A compression spring 13 is sleeved outside the slide rod 12 between the sliding plate 16 and the inner wall of the column 5.

[0034] It should be noted that when installing the sludge scraper 6, pull the pull plates 14 on the two columns 5, place the sludge scraper 6 at the ends of the two columns 5, connect the connection grooves 9 at both ends of the sludge scraper 6 with the connecting rods 10 correspondingly, so that the sludge scraper 6 is preliminarily connected between the two columns 5, and then loosen the pull plates 14, so that the end of the sliding rod 12 is correspondingly clamped into the fixing holes 15 on the connecting blocks 8 to fix the position of the sludge scraper 6.
