However, existing devices often directly flush the liquid through the filter screen for filtration. The liquid and the filter screen are in direct contact, and the contact point remains unchanged. Over time, the filter screen at the contact point is prone to blockage, requiring frequent replacement. Utility Model Content

[0032] like Figures 1 to 5As shown, the present invention discloses a filtration device for processing corrosion and scale inhibitors, comprising a filter barrel 1; a liquid inlet unit is provided at the top of the filter barrel 1; a liquid outlet pipe 11 is provided on the bottom side wall of the filter barrel 1; an annular groove 13 is provided on the inner wall of the filter barrel 1; an annular plate 14 is slidably connected in the annular groove 13; a filter screen 12 is fixedly connected to the inner wall of the annular plate 14; the filter screen 12 is conical; the filter screen 12 is rotated by a rotating unit; in the prior art, when producing corrosion and scale inhibitors, it is necessary to filter the corrosion and scale inhibitors to remove unreacted solid particles (such as phosphonocarboxylic acid polymers). To prevent clogs during subsequent use, existing devices often directly flush the liquid through the filter screen 12, resulting in direct contact between the liquid and the filter screen 12 at a fixed point. Over time, this can easily lead to clogging of the filter screen 12 at the contact point, requiring frequent replacement. To address this, the design of the liquid inlet unit and the rotating unit of the filter screen 12 prevents the liquid from flushing through the filter screen 12 at a fixed position, ensuring uniform use of the filter screen 12. The rotational force also helps to throw impurities to the edges. Furthermore, the conical design of the filter screen 12 further optimizes the filtration effect.

[0033] The liquid inlet unit includes a liquid inlet pipe 15; the top of the filter barrel 1 is fixedly connected to the liquid inlet pipe 15; a set of inverted L-shaped pipes 16 are opened on the pipe wall of the filter barrel 1; the bottom end of the liquid inlet pipe 15 is sealed and the cross section is conical.

[0034] The rotating unit includes a servo motor 2; the bottom end of the filter barrel 1 is fixedly connected to the servo motor 2; the output end of the servo motor 2 is provided with a first rotating shaft 21, and the top end of the first rotating shaft 21 extends into the filter barrel 1 and is fixedly connected to the middle of the bottom end of the filter screen 12.

[0035] During operation, the servo motor 2 starts and drives the filter screen 12 to rotate via the first rotating shaft 21. Then, the liquid of the corrosion and scale inhibitor enters through the inlet pipe 15 and flows out through a set of inverted L-shaped pipes 16, reducing the impact on the filter screen 12. At the same time, the rotation of the filter screen 12 ensures the uniformity of filtration and reduces the clogging and damage to the filter screen 12.

[0036] A backwash inlet pipe 3 is provided on the bottom side wall of the filter barrel 1; a backwash outlet pipe 31 is provided on the top side wall of the filter barrel 1, and the filter screen 12 is located at the backwash inlet pipe and the backwash outlet pipe 3; during operation, the filter screen 12 can be easily cleaned through the backwash inlet pipe 3 and the backwash outlet pipe 31, avoiding disassembly, which is convenient and quick.

[0037] A set of hinge rods 22 are hinged to the inner wall of the filter barrel 1, and a torsion spring is provided at the hinge; a vibrating ball 23 is rotatably connected to the end of the hinge rod 22; the hinge rod 22 is located below the filter screen 12; the hinge rod 22 is moved by a toggle element.

[0038] The actuating component includes an arc-shaped semicircular plate 24; the arc-shaped semicircular plate 24 is fixed to the bottom end of a set of annular plates 14, and the arc-shaped semicircular plate 24 is placed obliquely on the annular plates 14; during operation, the rotation of the first rotating shaft 21 will drive the filter screen 12 to rotate, and the rotation of the filter screen 12 will drive the annular plate 14 to rotate in the annular groove 13 (wherein the filter screen 12 is provided with support columns, etc., which is the prior art, and the filter screen 12 will not deform when it drives the annular plate 14 to rotate). When the annular plate 14 rotates, the arc-shaped semicircular plate 24, the hinge rod 22 and the torsion spring on the hinge rod 22 will drive the hinge rod 22 and the vibrating ball 23 to collide with the filter screen 12, reducing clogging and facilitating the efficiency of subsequent cleaning.

[0039] A scraper 32 is fixedly connected to the side wall of the filter barrel 1, and the scraper 32 is located above the filter screen 12, and the scraper 32 and the filter screen 12 are in close contact with each other. During operation, the scraper 32 is fixedly set, and the filter screen 12 is rotating, which can scrape the surface of the filter screen 12, making it convenient to clean the impurities on the surface of the filter screen 12.

[0040] The filter barrel 1 is equipped with a float ball 33 inside; a lifting rod 34 is fixedly connected to the float ball 33, and the top of the lifting rod 34 extends out of the filter barrel 1 and is fixedly connected to a baffle 35; an inverted L-shaped plate 36 is fixedly connected to the filter barrel 1, and the horizontal plate of the inverted L-shaped plate 36 is located directly above the baffle 35; the float ball 33 is located above the filter screen 12; during operation, when the corrosion and scale inhibitor is filtered, if the filter screen 12 becomes clogged, the water flow will be unable to go down, which will cause the float ball 33 to rise, thereby causing the lifting rod 34 and the baffle 35 to move upward. After contacting the inverted L-shaped plate 36, it will be sensed by the control system, and then the operation of the liquid inlet unit will be stopped to perform a backwashing operation.

[0041] Working principle: Firstly, the liquid inlet unit and the rotating unit of the filter screen 12 prevent liquid from flowing over the filter screen 12, ensuring uniformity of filter screen 12 operation. Simultaneously, the rotational force facilitates the throwing of impurities to the edges. The tapered design of the filter screen 12 further optimizes the filtration effect. The servo motor 2 starts, driving the filter screen 12 to rotate via the first rotating shaft 21. Then, the corrosion and scale inhibitor liquid enters through the inlet pipe 15 and flows out through a set of inverted L-shaped pipes 16, reducing the impact on the filter screen 12. The rotation of the filter screen 12 ensures uniform filtration, reducing clogging and damage. Backwashing is then performed... Water pipe 3 and backwash outlet pipe 31 facilitate the cleaning of filter screen 12 without disassembly, making it convenient and quick. The rotation of the first rotating shaft 21 drives the filter screen 12 to rotate, which in turn drives the annular plate 14 to rotate within the annular groove 13 (where the filter screen 12 is equipped with support columns, etc., which is existing technology, and the filter screen 12 will not deform when it drives the annular plate 14 to rotate). When the annular plate 14 rotates, it will drive the hinge rod 22 and the vibrating ball 23 to collide with the filter screen 12 through the arc-shaped semi-circular plate 24, the hinge rod 22 and the torsion spring on the hinge rod 22, thereby reducing clogging and improving the efficiency of subsequent cleaning.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
