Description

Technical Field

[0001] This utility model relates to the field of sludge settling technology, specifically a biomimetic gradient sludge settling system. Background Technology

[0002] Sludge settling is a crucial step in wastewater treatment, its core being the use of gravity to achieve solid-liquid separation. In facilities such as secondary settling tanks, activated sludge flocs and suspended particles in the mixed liquor gradually accumulate at the bottom through natural sedimentation, while the supernatant overflows and is discharged. The efficiency of this process directly affects the effluent quality and the cost of subsequent sludge treatment. Traditional settling systems mainly rely on geometric optimization (such as adding inclined plates and tubes) or chemical assistance to accelerate separation, but they are essentially still within the scope of static separation, making it difficult to coordinate the dynamic balance between settling velocity and sludge concentration. Especially when treating high-organic-matter or fibrous sludge, the mutual adsorption and bridging effects between particles can easily obstruct the settling path, forming a non-uniform settling layer, thereby weakening the overall separation effect.

[0003] Existing sedimentation equipment commonly uses a single-stage conical sludge hopper structure. Although it can achieve preliminary concentration through bottom contraction, it has three significant drawbacks: First, the single funnel structure cannot form an effective concentration gradient, and the mixed sedimentation of light and heavy sludge leads to drastic fluctuations in sludge concentration, with the high-concentration sludge layer often being diluted by the upper thin sludge layer; Second, the sludge discharge port is frequently blocked due to sludge caking or fiber entanglement, requiring mechanical stirring or high-pressure water backflushing to maintain operation, which not only increases energy consumption but also shortens the equipment life. To address these issues, we propose a biomimetic gradient sludge sedimentation system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a biomimetic gradient sludge settling system that can prevent the high-concentration sludge layer from being diluted by the upper thin sludge layer and can prevent sludge blockage, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biomimetic gradient sludge settling system, comprising support bars and settling components; Three corresponding fixing bars are fixed on the right side of the support bar; The settling assembly includes a first settling funnel, a second settling funnel, and a third settling funnel. The first settling funnel, the second settling funnel, and the third settling funnel are fixed sequentially from top to bottom on the right side of three fixing bars. The first settling funnel, the second settling funnel, and the third settling funnel are stacked together. An anti-clogging component is installed on the lower side of the third settling funnel, and an overflow component is installed on the upper side of the first settling funnel. A feeding component is installed on the upper side of the overflow component. The wastewater is set by setting up the settling assembly.

[0006] Furthermore, the overflow assembly includes a fixed frame, a baffle plate, and an overflow pipe. A fixed frame is fixed to the upper side of the first settling funnel, a baffle plate is fixed to the upper side of the fixed frame, an overflow hole is provided on the right side of the fixed frame, and an overflow pipe is fixed inside the overflow hole, through which low-concentration wastewater is discharged.

[0007] Furthermore, the feeding assembly includes a support plate, a sludge inlet pipe, a first solenoid valve, and a connecting flange ring. The support plate is fixed to the left end of the upper side of the fixed frame. An opening is provided in the middle of the support plate. The sludge inlet pipe is fixed inside the opening. The first solenoid valve is installed on the circumferential surface of the sludge inlet pipe. A connecting flange ring is fixed to the left end of the circumferential surface of the sludge inlet pipe. The right end of the sludge inlet pipe corresponds to the baffle plate. The input end of the first solenoid valve is electrically connected to the output end of an external control switch group. Wastewater enters the interior of the first settling funnel through the feeding assembly.

[0008] Furthermore, the anti-clogging component includes a sludge discharge pipe, a support frame, a motor, a rotating shaft, and cutting blades. The sludge discharge pipe is fixed to the lower side of the third settling funnel, and the support frame is fixed to the right side of the sludge discharge pipe. The motor is installed inside the support frame, and the rotating shaft is rotatably connected inside the sludge discharge pipe. The output shaft of the motor is fixed to the right end of the rotating shaft, and evenly distributed cutting blades are fixed on the circumferential surface of the rotating shaft. The input end of the motor is electrically connected to the output end of an external control switch group. By setting the anti-clogging component, clogging caused by high-concentration sludge after settling can be avoided.

[0009] Furthermore, a storage box is fixed to the lower right end of the support bar. An inclined groove is opened inside the storage box. Two corresponding guide blocks are fixed to the right end inside the storage box. A sludge outlet is fixed inside the sludge outlet on the right side of the storage box. A second solenoid valve is installed on the circumference of the sludge outlet. The input end of the second solenoid valve is electrically connected to the output end of an external control switch group. The high-concentration sludge after settling is stored by setting up the storage box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This biomimetic gradient sludge settling system has the following advantages: 1. This system achieves stepwise sludge settling and concentration stratification by using a vertical gradient structure composed of a first settling funnel, a second settling funnel, and a third settling funnel. During the settling process, the baffle plate and overflow pipe in the overflow component discharge low-concentration wastewater in the early stage to prevent the upper layer of thin sludge from mixing with the lower layer of high-concentration sludge, effectively maintaining the stability of the sludge concentration in each layer and avoiding the dilution phenomenon common in traditional settling systems, thereby improving sludge separation efficiency and concentration effect. 2. The anti-clogging component of the system uses a motor-driven rotating shaft and cutting blades to dynamically crush sludge clumps and fiber entanglements during the sludge discharge process, ensuring unobstructed flow through the sludge discharge pipe. This mechanism not only eliminates the risk of equipment failure caused by sludge caking or clogging, but also enhances the system's continuous operation capability and significantly reduces maintenance requirements and energy costs.

An anti-clogging component 6 is installed on the lower side of the third settling funnel 33.

The first settling funnel 31 includes a fixed frame 41, a baffle plate 42, and an overflow pipe 43. The fixed frame 41 is fixed to the upper side of the first settling funnel 31, and the baffle plate 42 is fixed to the upper side of the fixed frame 41. An overflow hole is provided on the right side of the fixed frame 41, and an overflow pipe 43 is fixed inside the overflow hole. The feeding assembly 5 includes a support plate 51, a sludge inlet pipe 52, a first solenoid valve 53, and a connecting flange ring 54. The support plate 51 is fixed to the upper left end of the fixed frame 41. An opening is provided in the middle of the support plate 51, and the sludge inlet pipe 52 is fixed inside the opening. A first solenoid valve 53 is installed on the circumferential surface of the inlet pipe 52. A connecting flange ring 54 is fixed to the left end of the circumferential surface of the sludge inlet pipe 52. The right end of the sludge inlet pipe 52 corresponds to the baffle plate 42. The input end of the first solenoid valve 53 is electrically connected to the output end of an external control switch group. The anti-clogging component 6 includes a sludge discharge pipe 61, a support frame 62, a motor 63, a rotating shaft 64, and a cutting blade 65. The sludge discharge pipe 61 is fixed to the lower side of the third settling funnel 33. The support frame 62 is fixed to the right side of the sludge discharge pipe 61. The support frame 62 is installed inside the support frame 62. There is a motor 63, and a rotating shaft 64 is rotatably connected inside the sludge discharge pipe 61. The output shaft of the motor 63 is fixed at the right end of the rotating shaft 64. Evenly distributed cutting blades 65 are fixed on the circumferential surface of the rotating shaft 64. The input end of the motor 63 is electrically connected to the output end of an external control switch group. By setting the anti-clogging component 6, the high-concentration sludge after settling can be prevented from clogging. The sewage enters the interior of the first settling funnel 31 through the feeding component and is discharged as low-concentration sewage through the overflow component 4. The sewage is set by the settling component 3.

[0015] Wherein: a storage box 7 is fixed at the lower right end of the support bar 1, an inclined groove 8 is opened inside the storage box 7, two corresponding guide blocks 9 are fixed at the right end inside the storage box 7, a sludge outlet 10 is fixed inside the sludge outlet on the right side of the storage box 7, a second solenoid valve 11 is installed on the circumference of the sludge outlet 10, and the input end of the second solenoid valve 11 is electrically connected to the output end of an external control switch group. The high-concentration sludge after settling is stored by setting up the storage box 7.

[0016] The working principle of the biomimetic gradient sludge settling system provided by this utility model is as follows: Wastewater enters the system through the sludge inlet pipe 52 of the feeding component 5. After the flow rate is regulated by the first solenoid valve 53, it impacts the baffle plate 42 to achieve uniform water flow distribution. The wastewater then flows into the first settling funnel 31, where primary gravity settling occurs, and suspended particles are initially enriched. Low-concentration wastewater is directly discharged from the system through the overflow pipe 43 on the right side of the fixed frame 41 to avoid diluting the high-concentration sludge at the bottom. The heavier sludge particles after settling slide into the second settling funnel 32. By extending the settling path to create a concentration gradient, sludge stratification and concentration are achieved. Finally, high-concentration sludge enters the bottom of the third settling funnel 33. At this point, the motor 63 of the anti-clogging component 6 drives the rotating shaft 64 to rotate the cutting blade 65, dynamically crushing clumps of sludge and tangled fibers, ensuring unobstructed flow through the sludge discharge pipe 61. The concentrated sludge then flows into the storage tank 7, where it is efficiently collected towards the sludge outlet under the guidance of the inclined trough 8 and the diversion effect of the guide block 9. When the second solenoid valve 11 opens, the high-concentration sludge is stably discharged through the sludge discharge pipe 10. Throughout the process, the vertical gradient structure formed by the superimposed first settling funnel 31, second settling funnel 32, and third settling funnel 33 creates a stratified sludge concentration of dilute, medium, and concentrated sludge through step-by-step concentration. The early diversion mechanism of the overflow component 4 ensures the stability of the concentration in each layer, while the continuous cutting action of the anti-clogging component 6 completely eliminates the risk of sludge clogging, achieving efficient and continuous sludge treatment.

[0017] It is worth noting that the external control switch group disclosed in the above embodiments is provided with buttons corresponding to the first solenoid valve 53, the second solenoid valve 11 and the motor 63. The first solenoid valve 53, the second solenoid valve 11 and the motor 63 can be freely configured according to the actual application scenario. The external control switch group controls the operation of the first solenoid valve 53, the second solenoid valve 11 and the motor 63 using methods commonly used in the prior art.
