[0027] Figure 2 This is a right - view structural schematic diagram of the sludge filtration device in the pipeline of the present utility model. Specific embodiments

[0028] The sludge filtration device in the pipeline of the present utility model will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation on the present utility model.

[0029] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the attached drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non - precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model.

[0030] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a sludge filtration device in a pipeline, including a connecting cylinder 1, a filter plate 2, and a driving assembly.

[0031] Specifically, a sewage channel 3 is provided through the middle of the connecting cylinder 1, and both ends of the sewage channel 3 are respectively connected to a sewage inlet pipeline and a sewage outlet pipeline.

[0032] The filter plate 2 is movably installed inside the connecting cylinder 1. Two filter mounting holes 4 are provided on the filter plate 2, and filter meshes 5 are arranged in the filter mounting holes 4. And the two filter meshes 5 are intermittently communicated with the sewage channel 3 through movement.

[0033] The driving assembly is installed on the connecting cylinder 1, and the driving assembly is in transmission connection with the filter plate 2 and drives the filter plate to move inside the connecting cylinder 1.

[0034] In this embodiment, the filter plate 2 is in close contact and sliding contact with the inner wall of the connecting cylinder 1. When one of the filter meshes 5 is docked with the sewage channel 3, the other filter mesh 5 is exposed outside the connecting cylinder 1. When one of the filter meshes 5 becomes blocked, the position of the filter plate 2 is adjusted by the driving assembly so that the other filter mesh 5 is connected to the sewage channel 3 to ensure the smooth progress of the sewage filtration operation. At the same time, the blocked filter mesh 5 is exposed outside the connecting cylinder 1, and at this time, the blocked filter mesh 5 can be flushed reversely, which is convenient for subsequent filtration operations.

[0035] To facilitate the connection between the sewage channel 3 and the external sewage inlet pipe and sewage outlet pipe, water inlet pipes 6 and outlet pipes 7 are respectively arranged at both ends of the sewage channel 3, and the water inlet pipes 6 and the outlet pipes 7 are fixedly connected to the outer side wall of the sewage channel 3.

[0036] In addition, cleaning grooves 8 are arranged at both ends of the connecting cylinder 1. The cleaning grooves 8 are used to clean the filter screen 5. When the filter screen 5 is exposed outside the connecting cylinder 1, the filter screen 5 is located in the cleaning grooves 8, and the filter screen 5 can be reversely flushed in the cleaning grooves 8, which is convenient for the filter screen 5 to continue to be used in the subsequent filtering process. At the same time, when there is a small amount of water leakage between the filter plate 2 and the connecting cylinder 1, the cleaning grooves 8 can play a role in overflowing the water flow. To facilitate the discharge of the cleaning liquid in the cleaning grooves 8, a sewage discharge valve is arranged at the bottom of the cleaning grooves.

[0037] Furthermore, the driving assembly includes a driving strip 9, a driving lead screw 10, and a driving motor 11.

[0038] Specifically, the driving strip 9 is fixedly installed on the filter plate 2, and the driving strip 9 penetrates through the top surface of the connecting cylinder 1 and is slidably arranged along the length direction of the connecting cylinder 1.

[0039] The driving lead screw 10 is rotatably installed on the top surface of the connecting cylinder 1, and the driving lead screw 10 is threadedly connected to the driving strip 9.

[0040] The driving motor 11 is installed on the side wall of the connecting cylinder 1, and the driving motor 11 is drivingly connected to the driving lead screw 10 through a worm and worm gear.

[0041] In this embodiment, the worm and worm gear includes a driving worm 12 and a driving worm wheel 13. The driving worm 12 is meshingly connected to the driving worm wheel 13. The driving worm 12 is drivingly connected to the driving motor 11, and the driving worm wheel 13 is fixedly installed on the driving lead screw 10.

[0042] When the position of the filter screen 5 needs to be adjusted, the driving motor 11 drives the filter plate 2 to move through the worm and worm gear, so that the sewage channel 3 is connected to the unclogged filter screen 5 to ensure the stable operation of the filtering operation. At the same time, the clogged filter screen 5 moves into the cleaning grooves 8 for cleaning. During this process, the worm and worm gear uses the self-locking principle to stably hold the filter plate 2 in the current position, realizing the stable connection between the sewage channel 3 and the filter screen 5.

[0043] It should be noted that the driving motor 11 adopts a servo motor, which can accurately control the angular displacement of the driving lead screw 10, and further can control the precise movement of the filter plate 2, so as to realize the precise docking between the sewage channel 3 and the filter screen 5.

[0044] Further, it further includes a controller and a pressure sensor 14.

[0045] Specifically, the controller is electrically connected to the drive motor 11 and the pressure sensor 14;

[0046] The pressure sensor 14 is arranged in the filter mounting hole 4, and the pressure sensor 14 is used to detect the water pressure change during the sewage filtration process.

[0047] In this embodiment, when the filter screen 5 is blocked, the pressures on the water inlet side and the water outlet side of the filter screen 5 increase and decrease respectively. The pressure sensor 14 installed in the filter mounting hole 4 detects the water pressure change to determine whether the filter screen 5 is blocked. When the filter screen 5 is blocked, after receiving the detection data of the pressure sensor 14, the controller controls the drive motor 11 to drive the filter plate 2 to move, so as to switch the filter screen 5 and ensure the smooth progress of the sewage pipeline filtration operation.

[0048] It should be noted that the data detection of the pressure sensor 14 and the control of the drive motor 11 belong to the prior art, and their specific circuit structures and control methods will not be elaborated here.

[0049] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0050] The present utility model drives the filter plate to move through the driving assembly, realizes the connection between the two filter screens and the sewage channel, and can clean the idle filter screen at the same time, which not only ensures the continuous and stable operation of the sewage filtration operation, but also can remove the filtered debris, effectively ensuring the filtration effect of the filtration device.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
