Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an inclined plate sedimentation system. Background Technology

[0002] In the fields of water supply, wastewater, and industrial water treatment, inclined plate sedimentation systems are widely used due to their high efficiency in solid-liquid separation. When treating wastewater with a pH value as high as 7 or above, calcium and magnesium ions in the water easily combine with carbonate ions to form insoluble substances such as calcium carbonate and magnesium hydroxide. These substances gradually accumulate in the sedimentation tank, forming a scale layer that adheres to the surface of the inclined plates.

[0003] To maintain normal system operation, the inclined plates need to be flushed regularly. However, the scale that accumulates after flushing falls into the sludge hopper. When too much scale accumulates, it is pumped into the sludge pump. As the scale flows within the sludge pump, it causes severe wear on the pump's moving parts (such as the impeller and seals), reducing pump efficiency and shortening its lifespan. This not only increases equipment maintenance costs but may also affect the normal operation of the entire water treatment system.

[0004] Therefore, existing inclined plate sedimentation systems suffer from scale buildup that damages components such as sludge pumps when treating high-pH wastewater. There is an urgent need to develop an inclined plate sedimentation system to solve this problem, thereby improving system reliability, extending equipment lifespan, and reducing maintenance costs. Utility Model Content

[0005] The purpose of this application is to provide an inclined plate sedimentation system to prevent scale on the inclined plate from damaging components such as the sludge pump when treating high pH wastewater.

[0006] The technical solution provided in this application is as follows:

[0007] An inclined plate sedimentation system, comprising:

[0008] A sedimentation tank includes a sedimentation tank body, an inclined plate, and a sludge hopper. The inclined plate is disposed within the sedimentation tank body, and the sludge hopper is disposed at the bottom of the sedimentation tank body.

[0009] The sludge collection assembly includes a sludge collection trough, a sludge discharge pipe, and a sludge discharge control valve. The sludge collection trough is located below and communicates with the sludge hopper. The sludge discharge pipe is connected to the sludge collection trough, and the sludge discharge control valve is located on the sludge discharge pipe.

[0010] The sludge discharge assembly includes a sludge discharge pipe and a sludge discharge pump, wherein the sludge discharge pipe is connected to the sludge hopper and the sludge discharge pump is mounted on the sludge discharge pipe.

[0011] In some embodiments, there are multiple sludge hoppers, which are arranged along the length of the sedimentation tank body at the bottom of the sedimentation tank body, and each sludge hopper is provided with a sludge collection assembly below it.

[0012] In some embodiments, a spray assembly is also included, which includes a main spray pipe, a high-pressure pump, a plurality of spray branch pipes and a plurality of nozzles. The main spray pipe is connected to the high-pressure pump, and one end of each of the plurality of spray branch pipes is connected to the main spray pipe, and the other end is provided with a nozzle, which is located above the inclined plate.

[0013] In some embodiments, a flushing pipe and a flushing control valve are also included. One end of the flushing pipe is connected to the main spray pipe, and the other end extends into the sedimentation tank body and extends along the length direction of the sedimentation tank body. The flushing pipe is located between the inclined plate and the sludge hopper. The portion of the flushing pipe that extends into the sedimentation tank body is provided with several holes evenly along the length direction.

[0014] The flushing control valve is located in the area where the flushing pipe is located outside the sedimentation tank body.

[0015] In some embodiments, a water outlet trough is also included, which is disposed on the top of the sedimentation tank body and has a plurality of triangular overflow ports.

[0016] In some embodiments, the number of triangular overflow outlets gradually increases from the front end to the rear end of the effluent channel along the length of the sedimentation tank body.

[0017] In some embodiments, a water outlet pipe is also included, which is connected to the water outlet tank.

[0018] In some embodiments, an inlet pipe and an inlet control valve are also included, wherein the inlet pipe is connected to the sedimentation tank body and the inlet control valve is disposed on the inlet pipe.

[0019] In some embodiments, the sludge discharge assembly further includes a sludge discharge flow meter and a suspended solids detector, which are respectively disposed on the sludge discharge pipe.

[0020] In some embodiments, a collection tank is also included, which is disposed directly below the slag collection tank.

[0021] The technical advantage of this application is that by setting a sludge collection component below the sludge hopper, after scale builds up on the inclined plate, the scale flakes washed off the inclined plate fall into the sludge collection trough below the sludge hopper and are then discharged through the sludge discharge pipe. This prevents the scale flakes from being drawn into the sludge discharge pump, thereby preventing the scale flakes from causing wear or damage to the blades and sealing rings of the sludge discharge pump, extending the service life of the sludge discharge pump, reducing the frequency of equipment maintenance and replacement, and lowering the operating cost of the system.

[0034] like Figure 1 As shown, in one or more embodiments, this disclosure provides an inclined plate sedimentation system, including a sedimentation tank 100, a sludge collection assembly 200, and a sludge discharge assembly 300. The sedimentation tank 100 includes a sedimentation tank body 110, an inclined plate 120, and a sludge hopper 130. The inclined plate 120 is disposed within the sedimentation tank body 110, and the sludge hopper 130 is disposed at the bottom of the sedimentation tank body 110. The sludge collection assembly 200 includes a sludge collection trough 210, a sludge discharge pipe 220, and a sludge discharge control valve 230. The sludge collection trough 210 is disposed below and communicates with the sludge hopper 130. The sludge discharge pipe 220 communicates with the sludge collection trough 210, and the sludge discharge control valve 230 is disposed on the sludge discharge pipe 220. The sludge discharge assembly 300 includes a sludge discharge pipe 310 and a sludge discharge pump 320. The sludge discharge pipe 310 communicates with the sludge hopper 130, and the sludge discharge pump 320 is disposed on the sludge discharge pipe 310.

[0035] Specifically, the sedimentation tank 100 is an integrated unit manufactured in the factory and can be directly installed on-site. This integrated design reduces installation difficulty and shortens the time required. The sedimentation tank 100 is supported by a bracket 400. The sedimentation tank body 110 is the core container of the sedimentation tank 100, typically a cuboid or circular structure, used to hold the wastewater to be treated. The sedimentation tank body 110 is generally made of reinforced concrete, fiberglass, or corrosion-resistant carbon steel, possessing good corrosion resistance and structural strength. An inlet pipe 140 is connected to the sedimentation tank body 110, and an inlet control valve 150 is installed on the inlet pipe 140. The inlet pipe 140 introduces the wastewater to be treated into the sedimentation tank 100, and the inlet control valve 150 controls the flow rate of wastewater entering the sedimentation tank 100. By adjusting the opening of the inlet control valve 150, the inlet flow rate can be flexibly controlled to adapt to different treatment needs. For example, when the wastewater concentration is high or the sedimentation tank needs maintenance, the load on the sedimentation tank can be reduced by decreasing the influent flow rate; when the treatment capacity is sufficient, the influent flow rate can be increased to improve treatment efficiency. The influent control valve 150 can be a manual valve, an electric valve, or a pneumatic valve.

[0036] Inclined plate 120 is a key component of sedimentation tank 100, composed of multiple parallel inclined plates. The inclined plate 120 is made of materials such as polypropylene (PP), polyvinyl chloride (PVC), or fiberglass, and features lightweight, high strength, corrosion resistance, and a smooth surface. The inclination angle of the inclined plate 120 is set according to the hydraulic conditions of sedimentation tank 100 and the properties of the sediment, while the length and width of the inclined plate 120 are set according to the size of sedimentation tank 100 and the water treatment capacity. The spacing between the inclined plates 120 is between 20 and 50 mm; too small a spacing will affect the smoothness of water flow, while too large a spacing will reduce sedimentation efficiency.

[0037] A sludge hopper 130 is located at the bottom of the sedimentation tank body 110 to collect settled sludge. The sludge hopper 130 is typically conical or bucket-shaped. The inner wall of the sludge hopper 130 is smooth to facilitate sludge sliding and discharge. A sludge discharge port is provided on the side wall of the sludge hopper 130, and a sludge discharge pipe 310 connects to the sludge hopper 130 through the discharge port to discharge the sludge from the sludge hopper 130 into the sedimentation tank 100. The diameter of the sludge discharge pipe 310 is set according to the sludge discharge volume and speed of the sludge hopper 130. The end of the sludge discharge pipe 310 can be connected to a sludge thickening tank, sludge dewatering equipment, or sludge storage tank for further treatment or storage of sludge. A sludge discharge pump 320 is installed on the sludge discharge pipe 310 to extract the sludge from the sludge hopper 130 and transport it to subsequent sludge treatment equipment or storage tanks. The inclined plate sedimentation system is programmed with a periodic sludge discharge program. The sludge discharge pump 320 is started at regular intervals to perform the sludge discharge operation.

[0038] A sludge collection trough 210 is installed below the sludge hopper 130, and is connected to the sludge hopper 130. The sludge collection trough 210 is used to collect scale flakes falling from the inclined plate 120. A sludge discharge pipe 220 is connected to the sludge collection trough 210, and a sludge discharge control valve 230 is installed on the sludge discharge pipe 220. The sludge discharge control valve 230 is opened periodically (opening at intervals and closing after a period of time) to discharge the scale flakes from the sludge collection trough 210. The interval between opening the sludge discharge control valve 230 and the sludge discharge time are set according to the specific project. Preferably, a collection tank 510 can be installed directly below the sludge collection trough 210. The scale flakes discharged from the sludge discharge pipe 220 are discharged into the collection tank 510, and the water in the collection tank 510 enters the trench 520 through a pipeline, finally cleaning the scale flakes in the collection tank 510.

[0039] When scale forms on the inclined plate 120, the sludge in the sludge hopper 130 can be first pumped out through the sludge discharge pipe 310 and the sludge discharge pump 320. Then, the inclined plate 120 is flushed, and the scale flakes on the inclined plate 120 fall into the sludge collection trough 210 below the sludge hopper 130. The scale flakes are then discharged from the sludge collection trough 210 through the sludge discharge pipe 220, preventing the scale flakes from being drawn into the sludge discharge pump 320. This avoids the scale flakes causing wear or damage to the blades and sealing rings of the sludge discharge pump 320, thus extending the service life of the sludge discharge pump 320, reducing the frequency of equipment maintenance and replacement, and lowering the system's operating costs. The sludge collection trough 210 is connected to the sludge hopper 130. When sludge enters the sludge collection trough 210, due to the light weight of the sludge, the sludge in the sludge collection trough 210 can be pumped out by the sludge discharge pump 320, reducing the amount of sludge discharged from the sludge discharge pipe 220. Furthermore, the scale flakes are heavy and not easily drawn into the sludge discharge pump 320.

[0040] In this embodiment, by installing a sludge collection assembly 200 below the sludge hopper 130, sludge is discharged through a sludge discharge pipe 310 connected to the sludge hopper 130, and scale is discharged through a sludge discharge pipe 220 connected to the sludge collection trough 210. This prevents scale from entering the sludge discharge system, thereby preventing damage to the sludge discharge pump 320 and extending the service life of the sludge discharge pump 320. It also reduces various problems caused by blockage and improves the stability and reliability of the system operation. Sludge and sludge discharge are completed automatically, with a high degree of automation and minimal manual operation.

[0041] In some embodiments, such as Figure 1 As shown, there are multiple sludge hoppers 130, which are arranged along the length of the sedimentation tank body 110 at the bottom of the sedimentation tank body 110. Each sludge hopper 130 is provided with a sludge collection component 200 below it.

[0042] Multiple sludge hoppers 130 are arranged along the length of the sedimentation tank body 110. When wastewater settles in the sedimentation tank 100, the sludge can be deposited more evenly into each sludge hopper 130, so that each sludge hopper 130 can effectively collect and store sludge, thereby improving the sedimentation efficiency of the entire sedimentation tank 100.

[0043] Each sludge hopper 130 is equipped with a sludge discharge assembly 300, allowing the sludge in each sludge hopper 130 to be discharged through the corresponding sludge discharge assembly 300. Each sludge hopper 130 is equipped with a sludge collection assembly 200 at its bottom, allowing the scale entering each sludge hopper 130 to be discharged through the sludge collection assembly 200, thus preventing the scale from damaging the sludge discharge pump 320.

[0044] In some embodiments, such as Figure 1 As shown, it also includes a spray assembly 600, which includes a main spray pipe 610, a high-pressure pump 620, multiple spray branch pipes 630 and multiple nozzles 640. The main spray pipe 610 is connected to the high-pressure pump 620. One end of each of the multiple spray branch pipes 630 is connected to the main spray pipe 610, and the other end is provided with a nozzle 640. The nozzles 640 are located above the inclined plate 120.

[0045] The wastewater in the sedimentation tank 100 may contain surfactants, which can easily cause foam to form on the surface of the wastewater, affecting its appearance. In this embodiment, a spray assembly 600 is installed above the inclined plate 120 to remove foam from the wastewater surface through spraying. Specifically, the main spray pipe 610 is connected to the outlet of the high-pressure pump 620, and the spray branch pipe 630 is connected to the main spray pipe 610. Water is sprayed onto the surface of the sedimentation tank 100 through the spray branch pipe 630 and nozzles 640 to eliminate foam. A spray control valve 650 is installed on the main spray pipe 610. The spray control valve 650 opens periodically, simultaneously starting the high-pressure pump 620. After a period of operation, the spray control valve 650 and the high-pressure pump 620 are closed, achieving automatic spraying to remove foam. The specific spraying time is determined by the specific project and is not limited in this embodiment. In this embodiment, the spraying is completed automatically, with a high degree of automation and minimal manual operation.

[0046] In some embodiments, such as Figure 1 As shown, it also includes a flushing pipe 660 and a flushing control valve 670. One end of the flushing pipe 660 is connected to the spray main pipe 610, and the other end extends into the sedimentation tank body 110 and extends along the length of the sedimentation tank body 110. The flushing pipe 660 is located between the inclined plate 120 and the sludge hopper 130. The part of the flushing pipe 660 that extends into the sedimentation tank body 110 is provided with several holes evenly distributed along the length. The flushing control valve 670 is located in the area where the flushing pipe 660 is located outside the sedimentation tank body 110.

[0047] In the inclined plate sedimentation system, the PAM flocculant added to the front end of the inclined plate 120 is a relatively viscous chemical that easily forms a network of deposits on the surface of the inclined plate 120, affecting the sedimentation effect. In this embodiment, a flushing pipe 660 is installed in the sedimentation tank 100 to flush the inclined plate 120, thereby washing off the deposits. Furthermore, the flushing pipe 660 shares the high-pressure pump 620 of the spray assembly 600, eliminating the need for additional power equipment and reducing operating costs. Specifically, the flushing pipe 660 is connected to the main spray pipe 610, and high-pressure water is pumped to the flushing pipe 660. The flushing pipe 660 has several holes to evenly distribute the high-pressure water onto the inclined plate 120, thereby flushing off the deposits on the surface of the inclined plate 120.

[0048] A flushing control valve 670 is installed on the flushing pipe 660. When the flushing control valve 670 is activated, the high-pressure pump 620 starts; when the flushing control valve 670 is closed, the high-pressure pump 620 shuts off. The flushing control valve 670 operates according to the pulse time, that is, it runs for a period of time, then closes for a period of time, and repeats this cycle. The number of repetitions and the flushing time are determined according to the actual project. Pulse flushing can generate a strong, instantaneous flushing force, which can better flush off the deposits on the inclined plate 120. During the flushing process, the inlet water of the sedimentation tank 100 needs to be shut off to prevent deposits from entering the effluent and reducing the quality of the effluent. In this embodiment, the flushing is completed automatically, with a high degree of automation and minimal manual operation.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the system also includes an outlet trough 160, which is located at the top of the sedimentation tank body 110. The outlet trough 160 has several triangular overflow ports 161. The outlet trough 160 is used to collect the treated water after sedimentation. The outlet trough 160 is typically a long strip structure arranged along the length of the sedimentation tank body 110. An outlet pipe 170 is connected to the outlet trough 160 to discharge the treated water from the outlet trough 160 into the sedimentation tank 100.

[0050] like Figure 2 As shown, the water outlet 160 is provided with a triangular overflow port 161. The triangular overflow port 161 has a triangular opening design, which allows the water to overflow in a relatively stable manner, avoiding excessive fluctuations or turbulence in the water outlet 160.

[0051] Preferred, such as Figure 2As shown, along the length of the sedimentation tank body 110, the number of triangular overflow ports 161 gradually increases from the front end to the rear end of the effluent trough 160. Existing effluent troughs 160 generally discharge water uniformly throughout, with a high concentration of suspended solids in the wastewater at the front end, resulting in a large accumulation of sediment in the front sludge hopper 130, while the rear end receives less, creating a highly uneven discharge. In this embodiment, the number of triangular overflow ports 161 gradually increases from the front end to the rear end, resulting in a relatively small discharge volume at the front end of the effluent trough 160 and a gradually increasing discharge volume at the rear end. This design allows the chemical sludge in the wastewater to settle more evenly in each sludge hopper 130 during the sedimentation process, rather than being concentrated at the front end of the sedimentation tank 100.

[0052] If the water flow from effluent tank 160 is uniform, it means that the water carrying chemical sludge did not completely pass through the inclined plate 120 for sedimentation. The amount of sludge gradually decreases as the water flows further down the slope, and the sedimentation effect follows suit. Therefore, even water flow may result in a situation where the first sludge hopper 130 contains a large amount of sludge, while the rear hopper contains very little. The difference in sludge amount between the two sludge hoppers 130 can be significant, affecting the sedimentation effect. At the same time, due to rapid settling, the water flow effect at the front end is far less than that at the rear end.

[0053] In this embodiment, the effluent trough 160 is designed with a small flow rate at the front end and a large flow rate at the rear end, allowing sludge to settle more evenly and preventing excessive solids flux in some areas. This maximizes the utilization of the sedimentation tank 100 and results in better effluent quality. Solids flux refers to the amount of solids settled per unit area. If the solids flux is too high, the settling effect will be poor, resulting in more suspended solids in the effluent.

[0054] In some embodiments, such as Figure 1 As shown, the sludge discharge assembly 300 also includes a sludge discharge flow meter 330 and a suspended solids detector 340, which are respectively installed on the sludge discharge pipe 310. During the sludge discharge process, the suspended solids in the discharged sludge-water mixture are monitored in real time. When the suspended solids fall below a set value, the sludge discharge pump 320 stops operating, the sludge discharge flow meter 330 records the sludge discharge flow rate in real time, and automatically calculates the total amount of suspended solids discharged daily for monitoring personnel to analyze the sludge discharge effect.

[0055] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
