[0025] Example 1:

[0026] Given the current issue of large impurities in wastewater affecting subsequent wastewater-sludge separation, please refer to [link / reference needed]. Figures 1-4 This utility model provides a technical solution: a sewage sludge separation device, including a separation chamber 1, a chamber door 2 hinged to the front of the separation chamber 1, a water collection chamber installed inside the separation chamber 1, a water outlet pipe fixedly installed on the right side of the separation chamber 1, a filter mechanism 3 installed on the left side of the separation chamber 1, and a separation mechanism 4 installed inside the separation chamber 1.

[0029] The filtration unit includes a connecting chamber 31, which is fixedly connected to the separation chamber 1 on its right side. A connecting pipe 32 is fixedly installed on the front of the connecting chamber 31, and a solenoid valve 33 is fixedly installed inside the connecting pipe 32. The connecting pipe 32 and the connecting chamber 31 are interconnected.

[0030] The right side of the connecting compartment 31 is provided with an installation groove, and the left side of the separating compartment 1 is provided with a connecting groove. The installation groove and the connecting groove correspond to each other. A grid frame 34 is fixedly installed inside the installation groove, and the right end of the grid frame 34 is fixedly connected to the inner wall of the connecting groove.

[0031] The connecting part includes an inclined plate 35, which is located below the connecting chamber 31. Connecting rods 36 are fixedly installed on both the front and rear sides of the inclined plate 35. The connecting rods 36 pass through the connecting chamber 31 and are connected to the bearing of the connecting chamber 31.

[0032] An electric hydraulic rod 37 is hinged to the left side of the separation chamber 1. There are two electric hydraulic rods 37, one at the front and one at the back. The telescopic end of the electric hydraulic rod 37 is hinged to the lower end of the inclined plate 35. A collection chamber 38 is located below the inclined plate 35. The right side of the collection chamber 38 is fixedly connected to the separation chamber 1.

[0033] Furthermore, in this embodiment, the wastewater containing sludge enters the connecting chamber 31 through the connecting pipe 32. The inclined plate 35 below the connecting chamber 31 is in an inclined state. The wastewater containing sludge in the connecting chamber 31 moves towards the separation chamber 1. The wastewater passes through the screen frame 34, which removes large impurities from the wastewater to facilitate the subsequent separation of sludge from the wastewater. The electric hydraulic rod 37 is activated. When the electric hydraulic rod 37 extends and retracts, it drives the inclined plate 35 to deflect, causing the inclined plate 35 to tilt to the left. The large impurities in the connecting chamber 31 first move to the left and enter the collection chamber 38 for collection.

[0034] Furthermore, this embodiment can effectively intercept large impurities in sewage by setting up the grid frame 34, removing these large impurities in advance to avoid clogging the equipment or affecting the treatment efficiency. When the electric hydraulic rod 37 extends and retracts, it drives the inclined plate 35 to deflect, causing the inclined plate 35 to tilt to the left. The large impurities in the connecting chamber 31 first move to the left and enter the collection chamber 38 for collection, which simplifies the cleaning work and reduces the risk of impurities scattering or being mixed into the sewage again.

[0035] Example 2:

[0036] Please see Figures 1-4 Furthermore, based on Embodiment 1, the separation section includes a fixed chamber 41, which is fixedly connected to the inner wall of the separation chamber 1. The fixed chamber 41 is interconnected with the connecting groove. A feed pipe 42 is fixedly installed at the lower end of the fixed chamber 41. A centrifugal chamber 44 is provided below the feed pipe 42. The lower end of the feed pipe 42 passes through the centrifugal chamber 44 and extends into the interior of the centrifugal chamber 44. A control valve is installed at the lower end of the centrifugal chamber 44.

[0037] The centrifuge chamber 44 is provided with a fixing plate 43 at both the upper and lower ends. The fixing plate 43 is fixedly connected to the inner wall of the separation chamber 1. The upper and lower ends of the centrifuge chamber 44 pass through the fixing plate 43 and are connected to the fixing plate 43 with a bearing.

[0038] The drive unit includes a fixed frame 45, the bottom surface of which is fixedly connected to the upper fixed plate 43. A motor 46 is fixedly mounted on the top surface of the fixed frame 45, and a rotating gear 47 is mounted below the motor 46. There are two rotating gears 47 on the left and right sides. The left rotating gear 47 is fixedly mounted on the outer side of the upper end of the centrifuge chamber 44, and the lower end of the right rotating gear 47 is connected to the upper fixed plate 43 by a bearing. The two rotating gears 47 mesh with each other. The output shaft of the motor 46 passes through the fixed frame 45 and is fixedly connected to the right rotating gear 47.

[0039] Furthermore, in this embodiment, the wastewater enters the fixed chamber 41 through the screen frame 34, and then enters the centrifuge chamber 44 through the feed pipe 42. The motor 46 is started, and the motor 46 drives the right rotating gear 47 to rotate. The right rotating gear 47 drives the left rotating gear 47 and the centrifuge chamber 44 to rotate. The centrifugal force generated when the centrifuge chamber 44 rotates separates the sludge in the wastewater in the centrifuge chamber 44. The separated wastewater is separated from the surface screen of the centrifuge chamber 44 and is discharged from the right outlet of the separation chamber 1 on the lower fixed plate 43. The sludge falls into the collection rack from below the centrifuge chamber 44.

[0040] Furthermore, in this embodiment, the centrifuge chamber 44 rotates under the drive of the motor 46, generating a strong centrifugal force. This centrifugal force can effectively separate the sludge particles from the water in the sewage. The separated sludge falls from below the centrifuge chamber 44 into the collection rack, which is convenient for centralized collection and treatment, avoiding sludge scattering and secondary pollution, and improving the efficiency and environmental friendliness of sludge treatment.

[0041] In use, wastewater containing sludge enters the connecting chamber 31 through the connecting pipe 32. The inclined plate 35 below the connecting chamber 31 is tilted. The wastewater containing sludge in the connecting chamber 31 moves towards the separation chamber 1. The wastewater passes through the screen frame 34, which removes large impurities from the wastewater, facilitating the subsequent separation of sludge. When the electric hydraulic rod 37 is activated, its extension and retraction cause the inclined plate 35 to deflect, tilting it to the left. The large impurities in the connecting chamber 31 first move to the left and are collected in the collection chamber 38. Water enters the fixed chamber 41 through the screen frame 34, and then enters the centrifuge chamber 44 through the feed pipe 42. The motor 46 is started, and the motor 46 drives the right rotating gear 47 to rotate. The right rotating gear 47 drives the left rotating gear 47 and the centrifuge chamber 44 to rotate. The centrifugal force generated when the centrifuge chamber 44 rotates separates the sludge in the sewage in the centrifuge chamber 44. The separated sewage is separated from the surface screen of the centrifuge chamber 44 and is discharged from the right outlet pipe of the separation chamber 1 on the lower fixed plate 43. The sludge falls into the collection rack from below the centrifuge chamber 44.
