DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-8The present invention provides an environmentally friendly filtering device for building water supply and drainage, including a box body 1, in which a filter plate 2 is arranged; further comprising a movable plate 3 and a limiting plate 4, on which a pressing rod 5 which is rotatably connected and slidingly matched with the top surface of the filter plate 2 is rotatably connected, a limiting rod 6 which movably penetrates the limiting plate 4 is arranged in the box body 1, and an elastic plate 7 which presses and rotates the filter plate 2 is arranged on the top of the limiting rod 6, a matching piece which cooperates with the rotation of the filter plate 2 is arranged between the limiting plate 4 and the limiting rod 6, and a movable piece which drives the movable plate 3 to make a circular motion is arranged on the limiting plate 4.

[0021] A filtering method of an environmentally friendly filtering device for building water supply and drainage, using the above-mentioned environmentally friendly filtering device for building water supply and drainage, the specific filtering method includes the following steps; S1, open the feed pipe and close the discharge pipe through the electromagnetic control valve, so that the sewage enters the box 1; S2, the feed pipe is closed and the discharge pipe is opened through the electromagnetic control valve, and the motor 10 is started at the same time, and the filter plate 2 is driven to move upward under the action of the movable parts, and moves from the bottom of the sewage to the sewage surface, thereby filtering the floating objects on the sewage surface; The filter plate 2 at the sewage outlet surface is tilted and slightly shaken under the action of the matching piece and the elastic plate 7; At the same time, the movable plate 3 cooperates with the movable pressing rod 5 to make the pressing rod 5 slide along the filter plate 2, so that the floating objects on the filter plate 2 enter the collection box 14; S3. Under the action of the movable parts, after the filter plate 2 penetrates into the sewage in the box body 1, the motor 10 is stopped, the discharge pipe is closed, and the feed pipe is opened, and the sewage is treated in a reciprocating manner.

[0022] The movable part includes a power part and two mutually meshing gears 8. A rotating plate 9 is fixedly connected to the central axis of the gear 8. The end of the rotating plate 9 passes through the end of the movable plate 3. The other end of the rotating plate 9 located at the bottom is rotatably connected to the limit plate 4. The limit plate 4 is in a U-shaped structure. The limit plate 4 is rotatably connected to the filter plate 2. The gear 8 located above is made to make circular motion and rotate by the power member. Due to the restriction of the limit rod 6 (the cross section of the limit rod 6 is rectangular), the limit plate 4 can only make up and down reciprocating motion, that is, one end of the two rotating plates 9 (the end away from the center axis of the gear 8) is on the same vertical plane. Under the action of the other ends of the two rotating plates 9, the movable plate 3 makes circular motion, the two gears 8 mesh with each other and rotate, and the gear 8 rotates relative to the movable plate 3. The movable plate 3 and the gear 8 make circular motion, while the limit plate 4 makes up-and-down reciprocating motion; When the circularly moving gear 8 moves to the highest position, the other ends of the two rotating plates 9 are closest to each other. At this time, the limit plate 4 drives the filter plate 2 to be closest to the gear 8 located below, so that the filter plate 2 moves out of the sewage surface, filters out the floating objects on the water surface, and separates the floating objects from the sewage. At this time, the filter plate 2 moves upward relative to the limit rod 6, and the elastic plate 7 contacts the filter plate 2 moving upward, and the filter plate 2 is tilted by the action of the matching member; At the same time, the filter plate 2 moves closer to the movable plate 3, so that the pressing rod 5 on the movable plate 3 slides along the filter plate 2, and the pressing plate rotates relative to the movable plate 3, thereby pushing the floating objects on the filter plate 2 and cleaning the floating objects; When the circularly moving gear 8 moves to the lowest position, the other ends of the two rotating plates 9 are farthest from each other. At this time, the limit plate 4 drives the filter plate 2 to be farthest from the gear 8 located below, so that the filter plate 2 is immersed in the sewage. That is, the filter plate 2 reciprocates up and down, and automatically tilts after emerging from the water surface, and makes the pressure rod 5 slide along the filter plate 2 for cleaning, reciprocating in sequence.

[0023] The power part includes a motor 10 connected and fixed to the box body 1, preferably a servo motor. The other end of the rotating plate 9 located at the top is connected and fixed to the output shaft of the motor 10. The motor 10 drives the rotating plate 9 located above to move, that is, one end of the rotating plate 9 rotates at the original position, and the other end makes a circular motion. The center axis of the gear 8 located above is connected and fixed to the other end of the rotating plate 9, so that the gear 8 makes a circular motion and rotates relative to the box body 1.

[0024] The matching part includes a horizontal plate 11 located on the top of the filter plate 2 and connected and fixed to the limit plate 4. The limit rod 6 is fixedly connected to a telescopic rod 12 with a compression member inside. The top of the telescopic rod 12 presses against the bottom of the filter plate 2, and the horizontal plate 11 presses against the top of the filter plate 2. Due to the limitation of the horizontal plate 11, the filter plate 2 cannot be tilted upwards and can only remain horizontal or rotate downwards; During the upward movement of the filter plate 2 under the water surface, that is, when the circularly moving gear 8 moves to the lowest position and moves upward, the filter plate 2 is located below the limit rod 6, and the telescopic rod 12 is tightly pressed against the bottom of the filter plate 2 under the action of the compression member, and cooperates with the horizontal plate 11 to keep the filter plate 2 in a horizontal state; When the filter plate 2 moves out of the water while maintaining a horizontal state, the filter plate 2 moves upward relative to the limit rod 6, and the filter plate 2 moves away from the telescopic rod 12. The compression effect of the compression member is reduced, so that the filter plate 2 presses the telescopic rod 12 to rotate downward. As the filter plate 2 rises to an increasing height, the downward inclination angle of the filter plate 2 gradually increases.

[0025] The gear 8 at the bottom is pressed against the elastic plate 7. When the gear 8 moves to the highest position in a circular motion, the filter plate 2 moves upward, and the gear 8 at the bottom presses against the elastic plate 7, causing the elastic plate 7 to bend, further causing the filter plate 2 to bend.

[0026] The movable plate 3 is a T-shaped structure, and the end of the movable plate 3 is rotatably connected to the pressure rod 5 through a torsion spring rod. Through the action of the torsion spring rod, the pressure rod 5 is ensured to fit tightly on the filter plate 2 at the water outlet and slide along the filter plate 2 for cleaning.

[0027] A feed pipe is provided on the top of the box body 1, a discharge pipe is provided on the bottom of the box body 1, and electromagnetic control valves are provided on the feed pipe and the discharge pipe. A cylinder device 13 is provided on the box body 1, and a collection box 14 that cooperates with the filter plate 2 is provided at the telescopic end of the cylinder device 13; When the filter plate 2 moves out of the water, the telescopic end of the cylinder device 13 moves the collection box 14, so that the end of the filter plate 2 is located at the top of the opening of the collection box 14, which is convenient for the subsequent tilting of the filter plate 2, and the pressing rod 5 cleans the floating objects on the filter plate 2, so that the floating objects are collected into the collection box 14; When the filter plate 2 moves downward, the telescopic end of the cylinder device 13 moves the collecting box 14 back to avoid conflict with the movement of the filter plate 2.

[0028] The pressing rod 5 slides along the inclined filter plate 2 .

[0029] The pressure rod 5 is an internal hollow structure, and a plurality of ventilation holes 15 are provided on the pressure rod 5. A blower 16 is provided on the side of the box body 1. The connecting hose of the blower 16 is connected to the pressure rod 5. After the filter plate 2 is out of the water, the pressure rod 5 slides along the inclined filter plate 2, so that the pressure rod 5 cleans the floating objects on the filter plate 2. In order to increase the cleaning effect of the pressure rod 5, the wind is blown through the ventilation holes 15 by the blower 16 to blow the floating objects on the filter plate 2, which helps to collect the floating objects in the collection box 14. In this solution, the pressing rod 5 can be a cleaning plate, a cleaning piece with a brush.
