DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a pipeline filter.

[0035] Reference Figure 1 and Figure 2 A pipeline filter comprises a three-way pipe body 1, wherein the three-way pipe body 1 is provided with a main pipe 11 and a branch pipe 12, wherein the main pipe 11 is connected with the branch pipe 12, wherein a filter plate 2 is fixedly arranged in the branch pipe 12, and sewage enters the branch pipe 12 through the main pipe 11 and collides with the filter plate 2 in the branch pipe 12. The filter plate 2 is evenly provided with a plurality of filter holes 21, and the filter holes 21 can block impurities and achieve the effect of filtering sewage.

[0036] Reference Figure 2 and Figure 3The branch pipe 12 is provided with a dredging assembly 5, which includes a connecting plate 51, two guide rods 52 and a plurality of dredging rods 53. The two guide rods 52 are fixedly connected to the connecting plate 51. The ends of the two guide rods 52 that are away from the connecting plate 51 are penetrated by the branch pipe 12 and are slidably connected to the branch pipe 12. When the guide rods 52 are manually pushed to move toward the direction close to the filter plate 2, the guide rods 52 drive the connecting plate 51 to move toward the direction close to the filter plate 2.

[0037] Reference Figure 2 and Figure 4 The dredging rod 53 is evenly fixedly connected to the connecting plate 51, and the dredging rod 53 corresponds to the filter hole 21 one by one. The filter hole 21 is arranged obliquely, the dredging rod 53 is coaxial with the corresponding filter hole 21, and the guide rod 52 is arranged parallel to the dredging rod 53. The connecting plate 51 pushes the dredging rod 53 to move in the direction close to the filter plate 2, so that the dredging rod 53 is inserted into the corresponding dredging hole 35, and the debris stuck in the filter hole 21 is pushed out of the filter hole 21, which can reduce the probability of clogging of the filter hole 21 and achieve the effect of dredging the filter hole 21.

[0038] Reference Figure 1 and Figure 2 The upper end of the branch pipe 12 is rotatably connected to the cover plate 13, and the cover plate 13 is slidably connected to the support frame 3. The branch pipe 12 is provided with a driving assembly 4, which includes a screw rod 41, a sliding rod 42, a first connecting rod 43, a second connecting rod 44 and a driving member 45 for driving the screw rod 41 to rotate. The driving member 45 includes a driving motor, and the output shaft of the driving motor is fixedly connected to the screw rod 41, and the output shaft of the driving motor drives the screw rod 41 to rotate.

[0039] Reference Figure 1 and Figure 2 , the two ends of the support frame 3 in the width direction are fixedly connected to the first connecting rod 43 and the second connecting rod 44 respectively, and the branch pipe 12 is provided with limiting grooves 14 on both sides along the radial direction, and the first connecting rod 43 and the second connecting rod 44 are respectively located in the corresponding limiting grooves 14, and the first connecting rod 43 and the second connecting rod 44 are both slidably connected to the branch pipe 12. The branch pipe 12 limits the first connecting rod 43 and the second connecting rod 44 through the limiting grooves 14, which can ensure the smooth movement of the first connecting rod 43 and the second connecting rod 44.

[0040] Reference Figure 1 and Figure 2The sliding rod 42 passes through the second connecting rod 44 and is slidably connected to the second connecting rod 44. The sliding rod 42 limits the second connecting rod 44, and then the second connecting rod 44 limits the support frame 3, which can ensure the stability of the movement of the support frame 3. The screw rod 41 passes through the first connecting rod 43 and is threadedly connected to the first connecting rod 43. The screw rod 41 drives the first connecting rod 43 to move along the axial direction of the branch pipe 12. The first connecting rod 43 pushes the support frame 3 to move along the axial direction of the branch pipe 12.

[0041] Reference Figure 1 and Figure 5 A dirt collecting box 31 is fixedly provided at the lower end of the support frame 3. The dirt collecting box 31 is arranged in the branch pipe 12 and one end close to the filter plate 2 is in conflict with the filter plate 2. The support frame 3 drives the dirt collecting box 31 to move in the direction close to the cover plate 13. The dirt collecting box 31 scrapes the impurities attached to the filter plate 2, which is beneficial to reduce the probability of clogging of the filter plate 2 and ensure the filtering efficiency of the filter plate 2 for sewage.

[0042] Reference Figure 1 and Figure 2 A debris removal basket 34 is provided in the dirt collection box 31, and a plurality of through holes 35 are provided in the debris removal basket 34. When the driving assembly 4 pulls the dirt collection box 31 upward through the support frame 3, the dirt collection box 31 collects the impurities attached to the filter plate 2 into the debris removal basket 34, and the through holes 35 can ensure that the sewage in the debris removal basket 34 can flow back into the branch pipe 12, thereby reducing the probability that the debris removal basket 34 brings out the sewage.

[0043] Reference Figure 1 and Figure 2 The driving assembly 4 continuously drives the supporting frame 3 to move upward, so that the dirt collecting box 31 can fully scrape the filter plate 2. When the dirt collecting box 31 conflicts with the cover plate 13, the dirt collecting box 31 pushes the cover plate 13 to flip over, and the cover plate 13 is opened. The operator can directly take out the debris removal basket 34 containing impurities, and place the clean debris removal basket 34 in the dirt collecting box 31, which is more convenient to clean the impurities.

[0044] Reference Figure 1 and Figure 4 The guide rod 52 is fixed with a limit baffle 54, the guide rod 52 is sleeved with a limit spring 55, and the branch pipe 12 is provided with an avoidance groove 15 adapted to the limit spring 55. The limit spring 55 is located in the avoidance groove 15, and the two connecting ends of the limit spring 55 are respectively fixedly connected to the branch pipe 12 and the limit baffle 54. When the operator presses the guide rod 52, the limit baffle 54 cooperates with the branch pipe 12 to squeeze the limit spring 55, so that the limit spring 55 undergoes elastic deformation.

[0045] Reference Figure 1 and Figure 2After the dirt collecting box 31 finishes scraping the filter plate 2, the operator releases the guide rod 52. The limit spring 55 rebounds and pushes the limit baffle 54, and the limit baffle 54 pulls the guide rod 52 to move away from the filter plate 2, thereby supporting the guide rod 52 and achieving the effect of limiting the guide rod 52. Then, the guide rod 52 limits the connection plate 51, so that a certain gap is maintained between the dredging rod 53 and the filter hole 21, thereby ensuring the filtering effect of the filter plate 2 on sewage.

[0046] Reference Figure 1 and Figure 6 After the operator completes the replacement of the trash basket 34, the driving assembly 4 drives the support frame 3 to move downward, and the support frame 3 then drives the dirt collection box 31 to move downward. A pressing plate 33 is fixedly arranged at one end of the support frame 3 close to the cover plate 13, and the pressing plate 33 is arranged outside the branch pipe 12. The support frame 3 drives the pressing plate 33 to move toward the branch pipe 12, so that the pressing plate 33 and the cover plate 13 are in close contact, which can reduce the probability of sewage leakage in the branch pipe 12 and improve the sealing effect of the cover plate 13 on the branch pipe 12.

[0047] Reference Figure 1 and Figure 6 The cover plate 13 is provided with a first inclined surface 16 along the circumferential direction, and the branch pipe 12 is provided with a second inclined surface 17 adapted to the first inclined surface 16. When the pressure plate 33 pushes the cover plate 13 to contact the branch pipe 12, the first inclined surface 16 and the second inclined surface 17 are in close contact. A sealing groove 18 is provided at the upper end of the branch pipe 12, and a sealing ring 19 is fixedly provided on the branch pipe 12, and the sealing ring 19 is arranged in the sealing groove 18. The pressure plate 33 pushes the cover plate 13, so that the cover plate 13 squeezes the sealing ring 19, reduces the probability of sewage leakage, and further improves the sealing effect of the cover plate 13 on the branch pipe 12.

[0048] Reference Figure 1 and Figure 6 The connecting plate 51 is provided with a plurality of water grooves 56 along the height direction, and the sewage collecting box 31 is provided with a plurality of water permeable holes 32. When the three-way pipe is working normally, the sewage can contact the filter plate 2 through the water permeable holes 32, and the filtered sewage can continue to flow through the water grooves 56, thereby reducing the probability of the connecting plate 51 and the sewage collecting box 31 blocking the flow of sewage, and ensuring the flow effect of sewage.

[0049] The implementation principle of a pipeline filter in the embodiment of the present application is as follows: a guide rod 52 is manually pushed to move in a direction close to the filter plate 2, and the guide rod 52 drives the connecting plate 51 to move in a direction close to the filter plate 2. The connecting plate 51 pushes the dredging rod 53 to move in a direction close to the filter plate 2, so that the dredging rod 53 is inserted into the corresponding dredging hole 35, and the debris stuck in the filter hole 21 is pushed out of the filter hole 21, which can reduce the probability of clogging of the filter hole 21 and achieve the effect of dredging the filter hole 21. The output shaft of the driving motor drives the screw rod 41 to rotate, and the sliding rod 42 limits the second connecting rod 44, which can ensure the stability of the movement of the support frame 3. The screw rod 41 drives the first connecting rod 43 to move along the axial direction of the branch pipe 12, so that the support frame 3 drives the dirt collecting box 31 to move in a direction close to the cover plate 13, and the dirt collecting box 31 scrapes the impurities attached to the filter plate 2, which is conducive to reducing the probability of clogging of the filter plate 2 and ensuring the filtering efficiency of the filter plate 2 for sewage.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
