Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to an intelligent sludge removal and dewatering device for sewage tanks. Background Technology

[0002] Wastewater treatment ponds are infrastructure used to collect, temporarily store, and preliminarily treat liquid pollutants such as domestic sewage and industrial wastewater. They can effectively intercept and settle solid impurities such as suspended solids and organic matter in domestic sewage and industrial wastewater, creating conditions for subsequent biochemical treatment and deep purification processes. They are widely used in municipal sewage treatment and industrial wastewater treatment and are one of the important links in the water treatment process.

[0003] During long-term operation, suspended solids, organic matter, and inorganic particles in sewage will gradually accumulate and form sludge. The accumulation of sludge will not only reduce the effective volume of the sewage tank and reduce the sewage treatment efficiency, but may also lead to poor water flow, anaerobic fermentation that produces foul-smelling gases, and even block pipes and corrode the tank structure.

[0004] In existing technologies, after long-term operation, sludge tends to accumulate at the bottom of sewage tanks and is unevenly distributed. Its thickness is difficult for personnel to detect, which affects the sludge removal operation of sewage tanks. The discharged sludge usually contains some water, which is easily lost and is not conducive to recycling. Furthermore, the high water content of the sludge will lead to increased transportation costs. Direct discharge or disposal may also cause secondary pollution, which is not conducive to the recycling of water resources. Utility Model Content

[0035] Example 1

[0036] Reference Figures 1 to 3 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0037] Wastewater tank 100;

[0038] A sludge removal unit 200 is installed on the sewage tank 100 and is used to clean the sludge in the sewage tank 100. A dewatering component 300 is installed on the sludge removal unit 200 and is used to dewater the sludge.

[0039] A reflux assembly 400 is installed on the dewatering assembly 300 and is used to reflux wastewater. A monitoring assembly 500 is installed inside the wastewater tank 100 and is used to detect the thickness of the sludge.

[0040] During use, the sludge removal unit 200 effectively removes sludge from the sewage tank, reducing the risk of manual operation. It works in conjunction with the dewatering component 300 to separate the solid and liquid sludge and dewater it, improving treatment efficiency and reducing the water content of the sludge. The return component 400 dewaters the sludge again, allowing the dewatered liquid to flow back into the tank, avoiding secondary pollution and improving water resource utilization. Meanwhile, the monitoring component 500 can monitor the sludge thickness in real time, providing data support for the sludge removal operation.

[0041] Example 2

[0042] Reference Figures 1 to 3 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0043] The sludge removal unit 200 includes two electric slide rails 201, which are fixedly connected to the two side surfaces of the sewage tank 100. A connecting block 202 is slidably connected inside the two electric slide rails 201, and a perforated plate 203 is fixedly connected to the two connecting blocks 202. The perforated plate 203 is sealed and fitted to the inner wall of the sewage tank 100. An inlet pipe 204 and an outlet pipe 205 are fixedly connected to the two side surfaces of the sewage tank 100, respectively.

[0044] The electric slide rails 201 on both sides are activated to drive the orifice plate 203 to slide horizontally within the sewage tank 100. The orifice plate 203 is sealed and fits tightly against the tank wall, and it also has a blocking effect on sludge, ensuring that no sludge overflows during sludge removal and guaranteeing the treatment effect. The inlet pipe 204 and outlet pipe 205 maintain the water circulation in the tank and can work with the electric slide rails 201 to make the orifice plate 203 reciprocate, improving sludge removal efficiency and reducing manual intervention.

[0045] Specifically, the dewatering component 300 includes a squeezing plate 301, which is fixedly connected to one side surface of the perforated plate 203. A partition 302 is fixedly connected to the inner wall of the sewage tank 100. A triangular plate 303 is fixedly connected to the bottom inner wall of the sewage tank 100. The triangular plate 303 matches the squeezing plate 301. A sludge discharge pipe 304 is fixedly connected to one side surface of the sewage tank 100. Valves 305 are fixedly connected to the sludge discharge pipe 304, the inlet pipe 204, and the outlet pipe 205.

[0046] Driven by the orifice plate 203, the sludge is mechanically squeezed, and solid-liquid separation is achieved in conjunction with the baffle plate 302. The lower notch of the baffle plate 302 is at the same vertical height as the squeezing plate 301. When the orifice plate 203 and the baffle plate 302 are in contact, the squeezing plate 301 fills the notch to prevent sludge backflow. The sludge is discharged through the sludge discharge pipe 304. The valve 305 can flexibly control the water flow and sludge discharge rhythm, effectively reducing the water content of the sludge and facilitating subsequent treatment.

[0047] Specifically, the reflux assembly 400 includes a strainer plate 401, which is fixedly connected to the wall of the sludge discharge pipe 304. A conduit 402 is fixedly connected to the sludge discharge pipe 304, and the other end of the conduit 402 is fixedly connected to a pump body 403. The pump body 403 is fixedly connected to the sewage tank 100.

[0048] The sludge in the sludge discharge pipe 304 is filtered by the sluice plate 401 and then pumped back to the sewage tank 100 by the pump body 403 through the conduit 402, so as to realize the recycling of sewage, reduce water waste and sewage treatment volume, avoid secondary pollution, and improve water resource utilization rate.

[0049] Specifically, the monitoring component 500 includes a support plate 501, which is fixedly connected to the inner wall of one side of the sewage tank 100, and an ultrasonic level gauge 502 is fixedly connected to the support plate 501.

[0050] In use, the ultrasonic level gauge 502 is fixed by the support plate 501, which can accurately monitor the thickness of sludge in the sewage tank 100 in real time, providing data support for sludge removal operations. When the sludge thickness reaches the set threshold, an alert is issued, achieving intelligent sludge removal and dewatering effects and avoiding errors from manual inspection. The ultrasonic level gauge 502 emits ultrasonic pulses to the bottom of the tank through its probe. The ultrasonic waves propagate in the water, and when they encounter the interface between water and sludge, some of the ultrasonic waves are reflected back. The probe of the level gauge receives the reflected waves. By measuring the time interval from the emission to the reception of the ultrasonic pulse, combined with the propagation speed of the ultrasonic waves in the water, the distance from the probe to the sludge surface can be calculated. Then, by subtracting the distance from the probe to the sludge surface from the total distance from the probe to the bottom of the tank, the thickness of the sludge can be obtained. Common ultrasonic level gauges 502 used in sewage tanks include Uson-11, LYUL600, and YR-550, which are all existing technologies and will not be discussed in detail in this article.

[0051] Example 3

[0052] Reference Figures 1 to 3 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0053] A square plate 101 is fixedly connected to one inner wall of the sewage tank 100. Multiple top blocks 102 are fixedly connected to the side surface of the square plate 101 near the perforated plate 203. The multiple top blocks 102 are all matched with the holes of the perforated plate 203.

[0054] The top block 102 on the square plate 101 is precisely matched with the holes of the perforated plate 203. When the perforated plate 203 slides to one side of the square plate 101 until it fits, it can automatically push off the impurities attached to the multiple holes of the perforated plate 203, avoiding manual cleaning of the perforated plate 203 to prevent blockage and ensuring dredging efficiency.

[0055] Specifically, two guide rods 103 are fixedly connected to one inner wall of the sewage tank 100. Both guide rods 103 movably pass through the perforated plate 203 and are fixedly connected to one side surface of the partition plate 302.

[0056] Both guide rods 103 penetrate the orifice plate 203 and are connected to the partition plate 302, which can guide the orifice plate 203 to slide smoothly along the inner wall of the sewage tank, avoid deviation or shaking, ensure the stability of sludge removal and dewatering operations, and at the same time enhance the sealing fit between the orifice plate 203 and the tank wall.

[0057] Specifically, a drain outlet 3021 is provided on the partition 302, and the drain outlet 3021 is horizontally higher than the extrusion plate 301.

[0058] When in use, the drain outlet 3021 is set higher than the extrusion plate 301, so that the water during the extrusion of sludge can flow back into the pool through the drain outlet 3021, avoiding water accumulation that affects the extrusion efficiency, and at the same time achieving solid-liquid separation, making the dewatering process smoother.

[0059] During use, the ultrasonic level gauge 502 is activated to monitor the sludge thickness in the sewage tank 100 in real time. When the set threshold is reached, the electric slide rail 201 is activated, driving the connecting block 202 and the perforated plate 203 to slide along one side of the sewage tank 100. The perforated plate 203 is sealed to the tank wall to ensure that the sludge does not overflow during the sludge removal process. As the perforated plate 203 slides, the squeezing plate 301 fixed on one side pushes the sludge towards the triangular plate 303 at the bottom of the sewage tank. The sludge is gradually squeezed and dehydrated under the cooperation of the squeezing plate 301 and the triangular plate 303. Since the drain port 3021 on the partition plate 302 is higher than the squeezing plate 301, the water in the sludge can pass through the drain port 3021 during the squeezing process. 021 flows back to one side of the sewage tank 100 to achieve initial solid-liquid separation. The dehydrated sludge is discharged through the sludge discharge pipe 304, and the perforated plate 401 in the sludge discharge pipe 304 further filters the residual water in the sludge, so that the water is pumped back into the sewage tank 100 through the conduit 402 and the pump body 403, thus completing the sludge removal process. When the perforated plate 203 slides to the other side of the sewage tank 100, the holes on the perforated plate 203 are aligned with the multiple top blocks 102 on the square plate 101. The top blocks 102 push down the impurities blocking the perforated plate 203. The inlet pipe 204 and the outlet pipe 205 work together to maintain the water circulation in the sewage tank 100. The valve 305 can control the opening and closing of the pipes according to the sludge removal requirements.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
