Description

Technical Field

[0001] The utility model relates to the technical field of scum cleaning, in particular to a full-automatic scum skimming device applied to a high-density sedimentation tank. Background Art

[0002] With the development of industry and the improvement of environmental protection requirements, high-density sedimentation tanks have been widely used in many fields as an efficient and energy-saving wastewater treatment equipment; however, during the operation of high-density sedimentation tanks, a large amount of scum will be generated. If these scum are not cleaned in time, it will not only affect the treatment effect of the sedimentation tank, but may also cause secondary pollution to the water quality.

[0003] In the process of removing scum, it is necessary to gently push the push plate across the water surface, and then push the scum to gather and then carry out centralized treatment. The water surface height of the sedimentation tank and the actual width of the sedimentation tank are inconsistent. If the push plate is too long, it cannot be placed in the sedimentation tank. In addition, the efficiency of manual scum removal is slow, which affects the water purification efficiency.

[0004] A Chinese patent discloses a scum removal device around a sedimentation tank (authorization announcement number CN215352157U). The patent technology is simple to operate and easy to use. By setting a locking mechanism and utilizing the mutual cooperation between the internal components of the locking mechanism, the relative position between the through rod and the connecting sleeve rod can be fixed. When the width of the inner cavity of the sedimentation tank body is different, the scraper with the same width as the inner cavity of the sedimentation tank body can be replaced to remove the scum, thereby improving the adaptability of the scum removal device.

[0005] However, it has certain disadvantages: it can only skim the scum in the sedimentation tank to one end of the sedimentation tank through the scraper, and the staff still needs to manually remove the scum afterwards. The labor intensity of the staff is still relatively high, and the entire scum cleaning and collection work cannot be completed automatically. Utility Model Content
