Technical Field

The utility model relates to the technical field of sewage treatment devices, and in particular to an impurity filtering mechanism for sewage treatment.

Background Art

Sewage is generally divided into industrial sewage and domestic sewage. Sewage treatment equipment can effectively treat domestic sewage and industrial wastewater in urban areas, and prevent sewage and pollutants from directly flowing into waters.

When filtering sewage, operators often use impurity filtering mechanisms to filter out impurities in the sewage so that the sewage can be treated in the next step. In actual use, although the existing impurity filtering mechanisms have basic filtering functions, a large amount of impurities are often attached to the screen during long-term use of the existing impurity filtering mechanisms, which greatly reduces the filtering capacity of the impurity filtering mechanisms. Since the screen is generally fixed inside the filtering mechanism, it is difficult for operators to clean the screen, so it needs to be improved.

A cleaning mechanism is arranged on the right side of the filter barrel 3;

Among them, the cleaning mechanism includes a No. 1 motor 7, which is fixedly installed on the right side of the upper surface of the base plate 1, and the other end of the output shaft of the No. 1 motor 7 is fixedly sleeved with a round shaft 8, and the outer surface of the round shaft 8 is fixedly sleeved with a rotating rod 9, and the other end of the rotating rod 9 is hinged with a connecting rod 10, and the other end of the connecting rod 10 is hinged with a connecting block 11, and the left end of the connecting block 11 passes through the rotating plate 12 and extends to the left side of the rotating plate 12, and the connecting block 11 is movably sleeved on the inner surface of the rotating plate 12. The rotating rod 9 rotates to make the connecting rod 10 push the connecting block 11 and the rotating plate 12 to move to the left as a whole.

When motor No. 1 7 is running, the circular shaft 8 will drive the rotating rod 9 to start rotating. At this time, the other end of the rotating rod 9 will drive the connecting rod 10 to rotate, so that the other end of the connecting rod 10 pushes the connecting block 11 to move to the left, and the movement of the connecting block 11 will drive the rotating plate 12, the push rod 13 and the push plate 14 to move to the left together.

Among them, bolts 15 are movably connected around the left surface of the closing plate 4, and the right end of the bolt 15 passes through the closing plate 4 and the filter barrel 3 in turn and extends to the interior of the filter barrel 3. The outer surface of the bolt 15 and the inner surface of the filter barrel 3 are threadedly connected, and the middle part of the left surface of the closing plate 4 is fixedly connected with a water inlet valve 16, and the right end of the water inlet valve 16 passes through the closing plate 4 and extends to the right surface of the closing plate 4.

Due to the design of the bolts 15, the closing plate 4 can be disassembled.

The outer surface of the filter barrel 3 is fixedly sleeved with a limiting ring 17 located on the left side of the installation sleeve 2 , and the outer surface of the filter barrel 3 is fixedly sleeved with a gear ring 18 located on the right side of the installation sleeve 2 .

Due to the design of the limiting ring 17 and the gear ring 18, the filter barrel 3 as a whole will not move left or right.

Due to the design of the water outlet valve 22 , the operator can discharge the sewage filtered inside the filter barrel 3 to the outside of the filter barrel 3 .

Among them, a No. 3 motor 25 is fixedly installed on the inner surface of the protective cover 23, and a rotating shaft 26 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 25. The left end of the outer surface of the rotating shaft 26 penetrates the hollow plate 24 and extends to the inside of the hollow plate 24 and is fixedly connected to the No. 2 gear 27.

When the third motor 25 is running, the rotating shaft 26 will drive the second gear 27 to start rotating.

The outer surfaces of the two fixed blocks 29 are movably connected to the inner surface of the fixed ring 6.

When the rotating shaft 26 rotates, the two second gears 27 start to move toward each other, and eventually the two fixing blocks 29 release the fixing of the fixing ring 6 .

The left and right sides of the inner surface of the hollow plate 24 are fixedly connected with the limiting blocks 30 , and the inner surface of the limiting blocks 30 and the outer surface of the tooth plate 28 are movably connected.

The limiting block 30 limits the movement of the tooth plate 28, thereby ensuring the stability of the two tooth plates 28 when moving as a whole.

The working principle and use process of this utility model:

First, the operator opens the water inlet valve 16 and passes the sewage into the interior of the filter barrel 3 and starts the No. 2 motor 19. Due to the meshing between the No. 1 gear 21 and the ring gear 18, the rotation of the No. 1 gear 21 will cause the ring gear 18 and the filter barrel 3 to start rotating as a whole. At this time, the overall rotation of the filter barrel 3 will cause the annular filter ring 5 in a rotating state to filter impurities in the sewage. When the filtration is completed, the operator opens the water outlet valve 22, and the filtered sewage in the filter barrel 3 will flow out to the outside of the filter barrel 3 through the water outlet valve 22.

When the annular filter ring 5 is clogged with impurities, the operator removes the three bolts 15 and takes down the closing plate 4 and then starts the No. 1 motor 7. As the No. 1 motor 7 runs, the circular shaft 8 drives the rotating rod 9 to start rotating, and the rotation of the rotating rod 9 drives the connecting rod 10 to rotate, so that the other end of the connecting rod 10 pushes the connecting block 11, the rotating plate 12, the push rod 13 and the push plate 14 to move to the left along the inner surface of the annular filter ring 5. In this process, the push plate 14 pushes the impurities inside the annular filter ring 5 to the outside of the filter barrel 3, thereby ensuring the filtering ability of the annular filter ring 5 for sewage impurities.

When the operator needs to replace the annular filter ring 5 and the fixing ring 6, the operator first removes the closing plate 4 and the bolts 15 and then starts the No. 3 motor 25. When the No. 3 motor 25 is running, the rotating shaft 26 and the No. 2 gear 27 will start to rotate. Due to the meshing between the No. 2 gear 27 and the tooth plate 28, the two tooth plates 28 will start to move towards each other as a whole under the drive of the No. 2 gear 27. Finally, the movement of the two tooth plates 28 will cause the two fixing blocks 29 to break away from the contact with the inner surface of the fixing ring 6. At this time, the fixing of the fixing ring 6 as a whole is released, and the operator can now take out the fixing ring 6 as a whole for replacement.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
