Description

Technical Field

[0001] The utility model relates to the technical field of inclined pipe flushing, in particular to an inclined pipe flushing device. Background Art

[0002] Inclined tubes are often used in sedimentation tanks to separate them into a series of shallow sedimentation layers, so that the treated and settled sludges move and separate in each shallow sedimentation layer. After the inclined tubes have been used for a period of time, a certain amount of sludge will accumulate and adhere to the inside of the inclined tubes. If they are not cleaned in time, the sedimentation effect of the inclined tubes will be further affected. In the prior art, high-pressure water guns or ventilation are usually used for flushing. For example, the patent with publication number CN220676859U discloses an inclined tube flushing device for a sedimentation tank. Specifically, a high-compression body is delivered to the blowing device through a gas delivery branch, and the sludge in the inclined tube is flushed by the high-compression body, and the sludge adhered to the inclined tube falls off under the action of the high-speed airflow.

[0003] However, the use of high compression bodies for flushing has disadvantages such as uneven airflow distribution, incomplete flushing, and sludge splashing out of the pipe mouth, resulting in cleaning blind spots.

[0004] Based on the above description, there is an urgent need for an inclined tube flushing device that can avoid sludge splashing and clean thoroughly. Utility Model Content

[0024] In this embodiment, the air flushing mechanism 2 is installed on the top of the sedimentation tank, wherein the servo motor drives multiple horizontal telescopic arms 21, thereby reciprocatingly pushing the vacuum assembly 22 to extract air and flush the inclined tube group 1; further, by installing a pair of strip baffles 23 at the air outlet end of the vacuum assembly 22, it is ensured that when flushing, when the sludge in the inclined tube group 1 is pressed, it is ensured that after the sludge splashes out of the inclined tube group 1 at the initial stage of flushing, it will not splash too far and can be scraped off along with the movement of the strip baffles 23.

[0025] In this embodiment, the strip baffle 23 can be made of flexible silicone or rubber material as a whole; it can also be made of hard steel sheets, etc., but if a hard material is used, it needs to be connected to the exhaust component 22 by an articulated component such as a hinge to ensure that the strip baffle 23 can be tilted and moved to scrape mud from the top of the inclined tube group 1.
