Description

Technical Field

[0001] The utility model relates to the technical field of mud-clearing grab bucket devices, in particular to a mud-clearing grab bucket device. Background Art

[0002] A large amount of sludge will be continuously deposited in the nitrification tank during the sewage treatment process, and the sludge needs to be cleaned out regularly to ensure the effective capacity of the tank and the quality of subsequent operations.

[0003] At present, large-scale mechanical equipment equipped with grab buckets is mostly used to excavate and clean the sludge in the pool. The existing announcement number CN211545688U discloses a leak-proof grab bucket, which can seal the gap formed by the closure of the two jaws by installing a side seam leak-proof component and a bottom seam leak-proof component on the jaws, thereby reducing the leakage of materials from the gap formed by the closure of the two jaws and avoiding the waste of materials. At present, most grab buckets use two or more bucket structures to obtain space for grabbing materials, but they are not suitable for wet sludge cleaning operations. The sludge will continue to adhere to the bucket wall and cannot be smoothly discharged when the grab bucket is opened. The sludge adhered to the bucket wall needs to be manually cleaned in time, which affects the sludge cleaning efficiency.

[0004] In summary, we consider designing a grab bucket suitable for cleaning viscous sludge, so that it can reduce the amount of sludge adhesion on the bucket wall and improve the sustainability of sludge cleaning; in view of this, we propose a sludge cleaning grab bucket device.
