[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model provides a sewage sludge separation and treatment device, such as... Figure 1-4 As shown, the sewage sludge separation and treatment device includes: a separation box 1 and a filter screen 2 disposed in the separation box 1 for filtering and separating large particles of sludge in the sewage; a mounting frame 3 mounted on one side of the separation box 1, on which a centrifuge box 4 is rotatably mounted, and the mounting frame 3 and the centrifuge box 4 are provided with a centrifugal mechanism for driving the sewage in the centrifuge box 4 to rotate and centrifuge to separate small particles of sludge; and a cleaning mechanism mounted on the separation box 1 for cleaning the sludge adhering to the filter screen 2.

[0022] In this embodiment, a controller of model OMRON E5CC-QX2ASM-800 is first installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. When separating sludge from sewage, the sewage is put into the separation tank 1. Through the interception effect of the filter screen 2, the larger sludge particles in the sewage can be blocked and filtered, initially achieving the separation of sewage from large sludge particles. This reduces the burden on subsequent separation processes and improves the overall separation efficiency. The separated sewage is pumped into the centrifuge tank 4. When a certain amount of sewage is put into the centrifuge tank 4, the sewage treatment is paused. When the centrifuge mechanism is started by the controller, the sewage in the centrifuge tank 4 can be rotated, and small sludge particles can be separated by centrifugation. Using the principle of centrifugal force, the small sludge particles are further separated from the sewage, which makes up for the inadequacy of relying solely on the filter screen 2 to separate large sludge particles. This improves the separation effect of sludge of different particle sizes in sewage and enhances the quality of sewage treatment. Through the entire device, sewage can be treated with different forms of sludge separation, effectively improving the sludge separation effect in sewage.

[0023] In a further preferred embodiment of the present invention, the centrifugation mechanism includes: a first servo motor 5 fixedly mounted on the outer wall of the mounting frame 3, and a mounting shaft 6 fixedly mounted on the output shaft of the first servo motor 5; and two spur gears 7 respectively fixedly sleeved on the mounting shaft 6 and the centrifuge box 4, the two spur gears 7 meshing with each other.

[0024] In this embodiment, when using the centrifugal mechanism, the controller starts the first servo motor 5 to drive the mounting shaft 6 to rotate. When the mounting shaft 6 rotates, it drives the sprocket 7 on it to rotate. Since the two sprockets 7 mesh with each other, they drive the sprocket 7 on the centrifuge box 4 to rotate, thus realizing the rotation of the centrifuge box 4. This, in turn, drives the sewage inside the centrifuge box 4 to rotate, which can centrifuge and separate small particles of sludge. By utilizing the principle of centrifugal force, the small particles of sludge are further separated from the sewage, which makes up for the shortcomings of relying solely on the filter screen 2 to separate large particles of sludge. This improves the separation effect of sludge of different particle sizes in sewage and enhances the quality of sewage treatment.

[0025] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a placement shaft 8 rotatably mounted on the filter screen 2, two cleaning brushes 9 fixedly mounted on the placement shaft 8, the two cleaning brushes 9 respectively contacting the inner and outer walls of the filter screen 2; a second servo motor 10 fixedly mounted on the outer wall of one side of the separation box 1; and a horizontal shaft 11 rotatably mounted on the separation box 1, one end of the horizontal shaft 11 being fixedly connected to the output shaft of the second servo motor 10, and both the horizontal shaft 11 and the placement shaft 8 being fixedly sleeved with bevel gears 12, the two bevel gears 12 meshing with each other.

[0026] In this embodiment, when it is necessary to clean the filter screen 2, a certain amount of clean water is placed in the separation box 1, and the second servo motor 10 is started by the controller to drive the horizontal shaft 11 to rotate. The horizontal shaft 11 transmits power, and the meshing bevel gear 12 drives the placement shaft 8 to rotate, thereby enabling the cleaning brush 9 to clean the filter screen 2. This effectively solves the problem of filter screen 2 clogging and improves the stability and processing efficiency of the sewage sludge separation and treatment device.

[0027] In a further preferred embodiment of the present invention, a drain pipe 13 for discharging sludge filtered by the filter screen 2 is fixedly installed at the bottom of the separation box 1. An auger 14 is rotatably installed inside the separation box 1. The top end of the auger 14 is fixedly connected to the bottom end of the placement shaft 8. The auger 14 extends into the drain pipe 13.

[0028] In this embodiment, when it is necessary to clean the sludge filtered in the separation box 1, the drain pipe 13 is opened, and the second servo motor 10 is started by the controller to drive the horizontal shaft 11 to rotate to a certain extent. The horizontal shaft 11 transmits power, and then the meshing bevel gear 12 drives the placement shaft 8 to rotate. When the placement shaft 8 rotates, it will drive the auger 14 to rotate, thereby speeding up the discharge of sludge from the separation box 1.

[0029] In a further preferred embodiment of this utility model, the separation box 1 is provided with a material extraction mechanism for pumping the filtered wastewater in the separation box 1 into the centrifuge box 4. The material extraction mechanism includes: a material extraction pump 15 fixedly installed on the separation box 1, the water inlet end of the material extraction pump 15 extending into the interior of the separation box 1; a connecting pipe 16 fixedly installed on the discharge end of the material extraction pump 15; and a material inlet is provided at the top of the centrifuge box 4. The connecting pipe 16 puts the wastewater into the centrifuge box 4 through the material inlet.

[0030] In this embodiment, when the wastewater after preliminary sludge removal in the separation tank 1 is pumped into the centrifuge tank 4, the feed inlet is opened and the pumping pump 15 is started. The wastewater enters the centrifuge tank 4 through the connecting pipe 16, realizing the effective transfer of wastewater from the filtration stage to the centrifugal separation stage, and improving the working efficiency and separation effect of the entire wastewater sludge separation and treatment device.

[0031] In a further preferred embodiment of the present invention, the centrifuge box 4 is provided with a plurality of drain outlets 17, which are used to discharge the clean water separated by centrifugation in the centrifuge box 4.

[0032] In this embodiment, small particles of sludge in the wastewater are separated to the edge or a specific area of ​​the centrifuge chamber 4 under centrifugal force, while the separated clean water is relatively concentrated in the center or upper area of ​​the centrifuge chamber 4. Depending on the location of the separated clean water, the drain outlet 17 near the clean water is opened, and the drain outlet 17 is connected to the corresponding collection pipe. The centrifuge chamber 4 is provided with a transparent observation port for viewing the position of the clean water.

[0033] In a further preferred embodiment of the present invention, the separation box 1 is provided with a feed pipe for putting sewage into the separation box 1, and the bottom of the centrifuge box 4 is provided with a cleaning pipe for cleaning the sludge separated in the centrifuge box 4.

[0034] In this embodiment, the wastewater to be treated is transported to the separation tank 1 through the feed pipe, so that the wastewater can begin to undergo preliminary filtration treatment in the separation tank 1. After the centrifuge 4 completes the centrifugal separation operation of the wastewater, the separated sludge will be deposited at the bottom of the centrifuge 4. The sludge can be cleaned out of the centrifuge 4 by opening the cleaning pipe.

[0035] In summary, compared with related technologies, this device can perform different forms of sludge separation treatment on sewage, effectively improving the sludge separation effect in sewage.
