DETAILED DESCRIPTION

The reset stretch belt 11 is made of flexible elastic material (preferably waterproof rubber material, and other materials can also be selected according to actual needs), and the elastic force of the reset stretch belt 11 is greater than the gravity of the reference rod 12 and the stopper 13. In the process of restoring the semi-elliptical filter 6 to the original shape, the reset stretch belt 11 overcomes the gravity of the reference rod 12 and the stopper 13 to pull the semi-elliptical filter 6 to restore to the original shape, so as to prevent the reference rod 12 and the stopper 13 from falling with the semi-elliptical filter 6 and affecting the restoration. The reset stretch belt 11 is located at the center position of the annular electromagnet 7. The pickling solution is conveyed into the filter box 3 by the liquid outlet pipe 2 for filtration, and then is sent back into the pickling tank body 1 by the reflux pipe 4 to realize circulating flow, which can effectively improve the pickling effect. In the inside of the filter box 3, the pickling solution passes through the semi-elliptical filter 6, and the impurities carried in the pickling solution are intercepted by the semi-elliptical filter 6, thereby playing a filtering role. Every time interval, the timing start-stop module starts the annular electromagnet 7 to generate a magnetic force. The annular electromagnet 7 magnetically repels the semi-elliptical filter 6, so that the semi-elliptical filter 6 is concave downward. In the process of the semi-elliptical filter 6 being concave downward, the impurity roll 10 is passed through. The impurity roll 10 is continuously expanded by the semi-elliptical filter 6. In this process, the impurity roll 10 scrapes off the impurities attached to the semi-elliptical filter 6, thereby realizing the cleaning of the semi-elliptical filter 6. In the process of the semi-elliptical filter 6 being continuously deformed downward, the magnetic force adjusting module gradually increases the magnetic force of the annular electromagnet 7, so as to ensure that the semi-elliptical filter 6 can smoothly pass through the impurity roll 10. When the semi-elliptical filter 6 is deformed in place, the magnetic property changing module changes the magnetic property of the annular electromagnet 7 by changing the current direction through the annular electromagnet 7, so that the annular electromagnet 7 generates a magnetic attraction force on the semi-elliptical filter 6. In addition, under the resilience of the reset stretch belt 11, the semi-elliptical filter 6 starts to slowly exit the impurity roll 10 until it restores to the original shape.

[0022] Second embodiment: Figure 3 、 12 It is shown that the middle part of the fiber filter screen 601 is further fixedly connected with the reference rod 12, and the reference rod 12 penetrates through the impurity roll 10. The lower end of the reference rod 12 is fixedly connected with the stopper 13. The reference rod 12 penetrates through the center hole of the impurity roll 10, so that the semi-elliptical filter 6 cannot be smoothly passed through the impurity roll 10 due to being washed by the water flow. The stopper 13 plays a role in resisting the impact of the water flow. When cleaning the semi-elliptical filter 6, the water flow impact force can be effectively reduced, thereby effectively improving the cleaning effect. Figure 12It is shown that the dam 13 comprises an impact-resistant seat 1301, and the lower end side wall of the impact-resistant seat 1301 is fixedly connected with a flexible water receiving film 1302, the inside of the flexible water receiving film 1302 is also filled with an elastic net 1307 (preferably made of waterproof rubber material, and other materials can also be selected according to actual needs), and the elastic net 1307 is a porous structure, which provides the flexible water receiving film 1302 with restoring elasticity, so that the water baffle 1305 can be self-adaptively adjusted according to the water flow impact force. The middle inner wall of the impact-resistant seat 1301 is provided with a main liquid cavity 1303 in communication with the inside of the flexible water receiving film 1302, and the inner wall of the impact-resistant seat 1301 is also provided with a plurality of equally spaced circumferentially distributed auxiliary liquid cavities 1304 in communication with the main liquid cavity 1303. The inner wall of the auxiliary liquid cavity 1304 is sealingly and slidingly connected with the water baffle 1305, and the plurality of water baffles 1305 are fixedly connected with the elastic belt 1306. The inside of the flexible water receiving film 1302 and the main liquid cavity 1303 and the auxiliary liquid cavity 1304 is simultaneously filled with hydraulic oil. The incoming water flow impacts on the flexible water receiving film 1302, and the flexible water receiving film 1302 is pressed to push the hydraulic oil outward to push the water baffle 1305, thereby increasing the contact area of the dam 13 with the water flow, thereby effectively improving the effect of resisting water flow impact, and the distance of the water baffle 1305 extending can be self-adaptively adjusted according to the water flow impact force. During the process of cleaning the semi-elliptical filter 6, a part of the water flow can be resisted, thereby effectively improving the cleaning effect of the semi-elliptical filter 6.

[0023] In combination with the current actual needs, the above-mentioned embodiments adopted by the present application are not limited to the scope, and various changes made within the knowledge possessed by those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
