DETAILED DESCRIPTION
[0023] Below, the utility model is further described in combination with the drawings and specific embodiments, and it is explained that, under the premise of not conflicting, the following described each embodiment or each technical feature can be combined to form a new embodiment.
[0024] Embodiment 1:
[0025] Please combineFigures 1-5 The self-powered self-cleaning filter of the embodiment comprises a valve body 1, the top of the valve body 1 is fixedly connected with a valve cover 2 through bolts, the valve body 1 and the valve cover 2 are made of carbon steel Q245R and are formed by welding, without the need of customizing a mold for casting, the cost is low and the production efficiency is high, the bottom of the valve body 1 is fixedly connected with an electromagnetic blowdown valve 3, the outside of the valve body 1 is fixedly connected with a time-delay relay module 4, an electric connection pressure gauge 5 is arranged on the outlet of the valve body 1, the lower part of the valve body 1 is fixedly connected with a bypass blowdown valve 7, a manual ball valve 8 is additionally arranged on the bypass blowdown valve 7, and the electromagnetic blowdown valve 3, the time-delay relay module 4 and the electric connection pressure gauge 5 are electrically connected through wires.
[0026] The self-cleaning assembly for automatically cleaning the filter core net 106 comprises a rotating fixed plate 101 fixedly connected inside the valve body 1, a stainless steel pipe shaft 102 rotatably connected with the top of the rotating fixed plate 101 through a copper shaft sleeve, a spiral scraper 103 fixedly connected with the outside of the stainless steel pipe shaft 102, cleaning brushes 104 uniformly arranged on the spiral scraper 103, an impeller 105 fixedly connected with the outside of the upper part of the stainless steel pipe shaft 102, a flow guide plate arranged on the inlet flange end of the valve body 1, and a filter core net 106 arranged on the rotating fixed plate 101 and laser-welded between the rotating fixed plate 101 and the filter core net 106, the outside of the spiral scraper 103 is in contact with the inner side of the filter core net 106, and the cleaning brushes 104 are designed in an inverted and L-shaped structure.
