[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] Example

[0021] See also Figures 1 to 4 , is an embodiment of the present utility model, which provides a technical solution: a fiber rotary disc filter with backwashing function, comprising

[0022] A machine body 1, a base shaft 2 rotatably mounted on the inner side of the machine body 1, and a plurality of filter discs 3 mounted on the surface of the base shaft 2;

[0023] Two backwash pumps 41 are provided at the bottom of the body 1, a main pipe 42 is provided at the water outlet of the backwash pump 41, a branch pipe 43 connected to the main pipe 42 and having its top end extending through the inside of the body 1, a transverse pipe 44 is connected to the top end of the branch pipe 43, and two backwash pipes 45 are installed on the transverse pipe 44 and are located on both sides of the filter disc 3. When the backwash pump 41 is subsequently started, water can be sent into the backwash pipe 45 through the main pipe 42, the branch pipe 43 and the transverse pipe 44, and the surface of the filter disc 3 can be washed through the backwash pipe 45;

[0024] The cleaning structure includes a support plate 51 welded and fixed to the inner side of the body 1, a support column 52 welded and fixed to the top surface of the support plate 51, a movable base plate 53 slidably sleeved on the surface of the support column 52, a plurality of bottom rods 54 welded and fixed to the bottom surface of the movable base plate 53, and a U-shaped brush holder 55 welded and fixed to the bottom end of the bottom rod 54. The top of the filter disc 3 is located on the inner side of the U-shaped brush holder 55, and the inner walls on both sides of the U-shaped brush holder 55 are provided with bristles 56 that contact the filter disc 3. The cleaning structure also includes a top slide seat 57 slidably set on the top surface of the movable base plate 53, a side clamping rod 58 welded and fixed to the side of the top slide seat 57, and a side clamping rod 58 opened on the support plate 53. There are two limit holes 59 on the surface of the column 52, and the two limit holes 59 are respectively located at the top and bottom ends of the support column 52. The side clamping rod 58 is inserted into one of the limit holes 59, which can stabilize the movable base plate 53 and the bottom rod 54 during daily use. The cleaning structure also includes a T-shaped slide 511 opened on the top surface of the movable base plate 53, a spring 512 installed in the T-shaped slide 511 and a T-shaped slider 510. The top end of the T-shaped slider 510 extends to the top surface of the movable base plate 53 and is fixed to the top slide seat 57. In actual use, when the operator starts the backwash pump 41 through the backwash pipe 45 When backwashing the surface of the filter disc 3, the operator can also slide the movable base plate 53 down to the top of the support plate 51, and make the U-shaped brush holder 55 be erected at the top edge of the filter disc 3, so that the filter disc 3 can contact the bristles 56 on the inner wall of the U-shaped brush holder 55 when it is in operation. The bristles 56 can be used to effectively brush and clean the surface of the filter disc 3 during the backwashing pipe 45, thereby improving the cleaning efficiency of the surface of the filter disc 3. When backwashing is stopped subsequently, the operator can pull the top slide 57 sideways to make the T-shaped slider 510 move sideways to compress the spring 512 and move the side clamping rod 58 out of the limit clamping hole 59, that is, The limit on the movable base plate 53 can be released. At this time, the movable base plate 53 is slid up to the top of the support column 52, and the U-shaped brush holder 55 is separated from the filter disc 3 until the side clamping rod 58 is aligned with the limit clamping hole 59 at the top of the support column 52. At this time, the top slide seat 57 is released. Under the push of the spring 512, the T-shaped slider 510 rebounds with the top slide seat 57, and finally the side clamping rod 58 can be inserted into the limit clamping hole 59 at the top of the support column 52, so that the movable base plate 53 and the U-shaped brush holder 55 can be limited after moving up, so that the U-shaped brush holder 55 will not block the normal use of the fiber rotary disc filter, and it is easy to use.

[0025] Among them, a cylindrical limiting groove is opened on the inner wall of one end of the T-shaped sliding groove 511, and one end of the spring 512 is inserted into the cylindrical limiting groove, which can assist in limiting the spring 512 and prevent the spring 512 from deviating.

[0026] Among them, a rectangular opening is opened on the top surface of the top sliding seat 57 to facilitate subsequent operators to push and pull the top sliding seat 57.

[0027] A water inlet pipe is provided at the top left side of the machine body 1 , and a water outlet pipe is provided at the bottom right side of the machine body 1 .

[0028] A hole is formed through the center of the movable base plate 53 , and the hole is matched with the support column 52 , so that the movable base plate 53 can slide up and down smoothly on the surface of the support column 52 .

[0029] The other structural principles of the fiber rotary disk filter itself in the utility model are all known technologies disclosed in existing patents. For details, please refer to the existing patent with publication number CN203971540U, and no further details will be given here.
