[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A sewage treatment floating foam filtering device, comprising a support rod beam frame, a clamping seat assembly, a hand-cranked fixed pulley assembly, a guiding fixed pulley, a floating filter screen assembly, a pneumatic push and swing assembly, a steel wire locking rope component, a corrosion-resistant sealing sleeve, an upper frame and a positioning collar assembly. The clamping seat assembly can be clamped on the upper edge of the sewage treatment facility. The support rod beam frame is installed on the clamping seat assembly. The hand-cranked fixed pulley assembly is installed on the side of the support rod beam frame. The guiding fixed pulley is installed on the upper top of the support rod beam frame. The upper frame is installed through the floating filter screen assembly. The positioning collar assembly is installed on the upper frame. One end of the steel wire locking rope component is connected to the positioning collar assembly. The middle of the steel wire locking rope component passes around the guiding fixed pulley. The other end of the steel wire locking rope component is fixedly installed on the hand-cranked fixed pulley assembly. The pneumatic push and swing assembly is installed on the upper part of the support rod beam frame. The installation position of the pneumatic push and swing assembly is below the guiding fixed pulley. The front section of the steel wire locking rope component passes through the pneumatic push and swing assembly. The steel wire locking rope component can be clamped by the pneumatic push and swing assembly. The steel wire locking rope component can be unclamped by the pneumatic push and swing assembly and move up and down in the middle of the pneumatic push and swing assembly. The outside periphery of the connection between the steel wire locking rope component, the positioning collar assembly and the upper frame is sleeved with a corrosion-resistant sealing sleeve.

[0006] Further, the pneumatic push and swing assembly includes a cylinder, a positioning box body, a double slide rail and a double clamping plate with locking. The double slide rail is fixedly installed inside the positioning box body. One side of the positioning box body is fixedly installed on the upper part of the support rod beam frame. The cylinder is fixedly installed on the outer side surface of the positioning box body. The push rod of the cylinder is fixedly connected to one side of the double clamping plate with locking. The double clamping plate with locking is installed through the double slide rail. A gas quick exhaust assembly is installed on the cylinder. The double clamping plate with locking can clamp the steel wire locking rope component passing through the pneumatic push and swing assembly. When gas is supplied, the push rod of the cylinder can push the double clamping plate with locking and the clamped steel wire locking rope component to move forward on the double slide rail. When the gas in the cylinder is exhausted by the gas quick exhaust assembly, the push rod of the cylinder can pull the double clamping plate with locking and the clamped steel wire locking rope component to move backward on the double slide rail. The steel wire locking rope component can be unclamped by the double clamping plate with locking in the pneumatic push and swing assembly and move up and down and out in the middle of the double clamping plate with locking.

[0007] Further, there is a middle through hole in the double clamping plate with locking. There are anti-slip clamping protrusions in the through hole. A locking component is installed at the bottom of the double clamping plate with locking. The steel wire locking rope component is installed through the middle through hole of the double clamping plate with locking. When the locking component is locked, the through hole in the middle of the double clamping plate with locking and the anti-slip clamping protrusions in the through hole can clamp the steel wire locking rope component. When the locking component is loosened, the steel wire locking rope component can move up and down and out in the middle through hole of the double clamping plate with locking.

[0008] Further, the engaging seat assembly includes a U-shaped engaging seat and a positioning bolt. The U-shaped engaging seat is clamped on the upper edge of the sewage treatment facility, and the positioning bolt is inserted through the side of the U-shaped engaging seat. When the positioning bolt is rotated outward to loosen, the U-shaped engaging seat can move on the upper edge of the sewage treatment facility. When the positioning bolt is screwed inward, the U-shaped engaging seat can be integrally fixed on the upper edge of the sewage treatment facility. There is an installation jack on the U-shaped engaging seat, and the bottom of the support rod beam can be fixedly installed in the jack on the U-shaped engaging seat.

When the positioning bolt is screwed inward, the U-shaped engaging seat and the support rod beam can be integrally fixed on the upper edge of the sewage treatment facility.

[0009] Further, there are four sets of the support rod beam, the engaging seat assembly, the hand-cranked fixed pulley assembly, the guiding fixed pulley, the air-pushed swing assembly, the wire locking rope member, the corrosion-resistant sealing sleeve, and the positioning collar assembly. The four sets of positioning collar assemblies are respectively installed at the four corners of the upper frame of the floating filter screen assembly. One end of the wire locking rope member is fixedly connected to the positioning collar assembly, and the corrosion-resistant sealing sleeve is fixedly sleeved at the connection of the wire locking rope member, the positioning collar assembly, and the upper frame. The wire locking rope member is sequentially inserted through the middle through hole of the double locking card plate in the air-pushed swing assembly and the guiding fixed pulley at the top of the corresponding support rod beam. The other end of the wire locking rope member is fixed on the hand-cranked fixed pulley assembly on the side of the corresponding support rod beam, and the bottom of the corresponding support rod beam is fixedly installed in the installation jack on the U-shaped engaging seat in the corresponding engaging seat assembly. When the hand-cranked fixed pulley assembly is rotated by hand, the hand-cranked fixed pulley assembly can drive the wire locking rope member to move up and down in the guiding fixed pulley and the through hole of the double locking card plate of the air-pushed swing assembly. One end of the wire locking rope member can drive the upper frame of the floating filter screen assembly and the floating filter screen assembly to move up and down together. The floating filter screen assembly can rinse and filter the foam, impurities, or other floating objects in the sewage tank during the sewage treatment process. When it is necessary to swing the floating filter screen assembly, lock the locking member in the double locking card plate. When the air is supplied, the cylinder push rod can push the double locking card plate and the clamped wire locking rope member to move forward on the double slide rails. When the gas quick exhaust assembly discharges the gas in the cylinder, the cylinder push rod can pull the double locking card plate and the clamped wire locking rope member to move backward on the double slide rails, thereby driving the floating filter screen assembly to perform a swinging motion.

[0010] When it is necessary to move the hand-cranked fixed pulley assembly, guiding fixed pulley, pneumatic push and swing assembly, steel wire rope locking piece, corrosion-resistant sealing sleeve, positioning collar assembly, upper frame and floating filter screen assembly as a whole, rotate the positioning bolt on the side of the U-shaped clamping seat in the clamping seat assembly outward to loosen it, so that the U-shaped clamping seat and the supporting rod beam frame installed on the U-shaped clamping seat can move above the upper edge of the sewage treatment facility. When it needs to be fixed at a specific position, rotate the positioning bolt on the side of the U-shaped clamping seat in the clamping seat assembly inward, and the U-shaped clamping seat and the supporting rod beam frame installed on the U-shaped clamping seat can be fixed at a specific position above the upper edge of the sewage treatment facility.
