Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a grille for a V-shaped sewage treatment filter tank. Background Art

[0002] The V-shaped filter tank is a water treatment structure in a water plant, referring to a rapid filter tank that filters at a constant water level. The water inlet troughs on both sides of the tank are V-shaped. The ultrasonic water level automatic control device in the tank can adjust the outlet clear water valve. The valve can automatically adjust the opening degree according to the height of the water level in the tank to keep the water level in the tank constant. The V-shaped filter tank is a form of sewage treatment filtration. Its working principle is as follows: The water to be filtered flows from the total water inlet channel through the inlet valve and square holes, then overflows the weir opening and enters the V-shaped trough submerged by the water to be filtered through the side holes. It respectively enters the filter tank through the evenly distributed water distribution holes at the bottom of the trough and the V-shaped trough weir. The filtered water filtered by the homogeneous filter media filter layer flows into the bottom space through the long-stem filter heads, converges into the air-water distribution pipe channel through the square holes, and then flows into the clear water tank through the water seal well, outlet weir, and clear water channel in the pipe gallery.

[0003] For example, the Chinese utility model patent (CN217961491U) discloses a grille for a V-shaped sewage treatment filter tank, which records: "By setting the filter screen, it effectively intercepts the items inside the water storage tank, prevents the filter from entering the water storage tank and causing blockage, and achieves the advantage of protecting the water storage tank. By setting the gear assembly, it can change the rotation direction of the output motor, drive the screw to rotate by the gear assembly, so that the screw drives the filter screen to move upward, enabling the staff to clean the inside of the filter screen", and also records the technical problems of "After using for a period of time, the filter is easy to block the single-layer sand filter material, affecting subsequent use, and frequently cleaning or even replacing the single-layer sand filter material. Moreover, the filter tank works outdoors, and the falling of objects such as garbage bags into it will also increase the work burden".

[0043] Embodiment 2:

[0044] The V-shaped sewage treatment filter grille provided in Embodiment 1 is further optimized. Specifically, as Figures 5 - 6 shown, the support rod group 3 includes a support rod body 16. Movable end rods 17 are slidably connected to both ends of the support rod body 16. Buckling frames 18 are fixedly connected to the ends of the movable end rods 17 away from the support rod body 16. The buckling frames 18 are buckled and connected with the connecting rods 9 in the filter screen frame 4.

[0045] Further, movable cavities 19 are provided at both ends of the support rod body 16. One end of the movable end rod 17 is inserted into the interior of the movable cavity 19.

The limit sliding blocks 22 are located inside the limit sliding groove 21, and the limit sliding blocks 22 are slidably connected to the limit sliding groove 21.

[0047] Through the above structural design, the movable end rod 17 can be snap-connected to the connecting rod 9 in the filter mesh frame 4 on the same side through the snap-fit frame 18 at the end. The thrust spring 20 provided inside the short end of the support rod body 16 pushes the movable end rod 17 to drive the snap-fit frame 18 to continuously support the filter mesh group 2, thereby effectively reducing the bending phenomenon of the filter mesh group 2; through the cooperation of the limit sliding groove 21 and the limit sliding block 22, the movable end rod 17 can be effectively prevented from disengaging from the end of the support rod body 16. When the filter mesh group 2 needs to be removed and replaced, only the movable end rod 17 needs to be moved towards the support rod body 16 to separate the snap-fit frame 18 from the connecting rod 9 in the filter mesh frame 4, so that the filter mesh group 2 can be removed and replaced, and at the same time, the support rod group 3 is also disassembled.
