[0026] The sewage solid waste separation device of the present utility model will be described in more detail below in conjunction with 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.

[0027] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the embodiments of the present utility model.

[0028] As Figures 1 to 3 shown, an embodiment of the present utility model provides a sewage solid waste separation device, which includes an installation housing 1, a filter wheel 2, and a driving member.

[0029] Specifically, the installation housing 1 has a hollow structure, and a filter window 3 and a cleaning window 4 are penetratingly provided on the installation housing 1. The filter window 3 and the cleaning window 4 are respectively used for sludge filtration and sludge cleaning.

[0030] The filter wheel 2 is rotatably installed inside the installation housing 1 through a rotating shaft 6, and a plurality of filters 5 matching the filter window 3 are provided on the filter wheel 2. The plurality of filters 5 are distributed in a circular pattern, and the filters 5 are arranged at equal intervals.

[0031] The driving member is in transmission connection with the rotating shaft 6, and the driving member drives the filter wheel 2 to rotate to switch and dock with the filter window 3 and the cleaning window 4.

[0032] In this embodiment, docking installation pipes 7 are provided outside the two filter windows 3, and the docking installation pipes 7 are fixedly installed on the outer side wall of the installation housing 1. During installation, the two docking installation pipes 7 are connected to the sewage pipeline. When the sewage passes through the filter 5, the filter 5 filters the sludge in the sewage.

[0033] When the filter 5 filters a large amount of sludge and becomes blocked, the driving member drives the filter wheel 2 to rotate, and the positions of the filters 5 on the filter wheel 2 change and re-dock with the filter window 3 and the cleaning window 4. At this time, the filter 5 without sludge blockage is in the filter window 3 and can continue to filter the sludge. At the same time, the filter 5 blocked by sludge docks with the cleaning window 4, and the filter 5 can be cleaned by reverse flushing.

[0034] In a specific embodiment, a pressure sensor 8 is fixedly mounted on the inner wall of the docking installation pipe 7, and the pressure sensor 8 is located in the docking installation pipe 7 on the water inlet side. When the filter 5 is clogged, the pressure in the pipeline increases, and after the pressure sensor 8 senses the increase in water pressure, its detection signal is transmitted to the controller, and the controller is used to control the driving member to act, thereby realizing the online switching and cleaning operation of the filter 5, and also ensuring the continuous filtering operation of sewage sludge in the pipeline.

[0035] In addition, the filter wheel 2 is fitted and in sliding contact with the inner wall of the mounting housing 1. The filter wheel 2 and the inner wall of the mounting housing 1 can be movably connected through a dynamic seal, which ensures that the filter wheel 2 can rotate and enables the filter 5 to dock with the filter window 3 and the cleaning window 4. On the other hand, it prevents the sewage in the pipeline from passing through the gap between the filter wheel 2 and the mounting housing 1 and overflowing from the cleaning window 4, ensuring that the sludge filtering device can work stably.

[0036] It should be noted that there are multiple filters 5 distributed in a circle, and the more filters there are, the shorter the time it takes for the filter 5 to switch and dock with the filter window 3, so a quick response can be obtained, and it can be ensured that the water pressure in the sewage pipe will not surge, thereby ensuring the safety of the sewage pipe.

[0037] In addition, the processing of the detection signal of the pressure sensor 8 and the control of the driving element by the controller belong to the existing technology, and its specific circuit structure and processing method are not described in detail here.

[0038] Furthermore, the driving component includes a mounting frame 9 and a driving motor 10 .

[0039] Specifically, the mounting frame 9 is fixedly mounted on the outer side wall of the mounting shell 1 .

[0040] The driving motor 10 is fixedly mounted on the mounting frame 9 , and the driving motor 10 is drivingly connected to the rotating shaft 6 .

[0041] In this embodiment, the filter wheel 2 rotates around the rotating shaft 6 under the drive of the driving motor 10. When the filter 5 involved in the sludge filtration is blocked, the driving motor 10 drives the rotating shaft 6 and the filter wheel 2 to rotate, and the blocked filter 5 is switched to the cleaning window 4 position, and the filter 5 can be washed by reverse flushing. At the same time, the new filter 5 is docked with the filter window 3 to filter the sludge in the pipeline. The combination of the two realizes the online switching of the filter 5 and ensures the continuous sludge filtering operation in the pipeline.

[0042] In a specific embodiment, the drive motor 10 is a servo motor. A servo motor is a high-precision motor that is mainly used to accurately control the position, speed, and acceleration of mechanical equipment. It is widely used in automation equipment, robots, CNC machine tools, medical equipment, aerospace, and other fields. A servo motor can achieve very precise position control and is usually used with an encoder to provide feedback signals to ensure that the output of the motor is consistent with expectations.

[0043] The driving motor 10 is a servo motor, which can accurately achieve the precise docking of the filter 5 with the filter window 3 and the cleaning window 4, thereby ensuring the stable sludge filtering operation in the pipeline.

[0044] Furthermore, the driving motor 10 and the rotating shaft 6 are connected via a worm gear assembly.

[0045] Specifically, the worm gear assembly includes a driving worm 11 and a transmission worm wheel 12, the driving worm 11 is meshingly connected with the transmission worm wheel 12, the driving worm 11 is transmission-connected to the output shaft of the driving motor 10, and the transmission worm wheel 12 is fixedly connected to the end of the rotating shaft 6.

[0046] In this embodiment, due to the self-locking between the driving worm 11 and the transmission worm wheel 12, when the filter 5 is respectively docked with the filter window 3 and the cleaning window 4, the driving motor 10 stops working. At this time, the filter 5 can stably maintain the docking state with the filter window 3 and the cleaning window 4, ensuring the smooth progress of the filtering operation and the cleaning operation.

[0047] Compared with the prior art, the utility model has at least the following beneficial effects:

[0048] The utility model utilizes the rotation of the filter wheel to quickly realize the docking and switching of the filter, the filter window and the cleaning window, can switch the filter online without affecting the normal use of the pipeline, and has the function of continuous cleaning use, and has the characteristics of simple structure and convenient operation.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
