Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically to a wastewater interception device for wastewater treatment ponds. Background Technology

[0002] Wastewater treatment ponds refer to a general term for water treatment structures that use physical, chemical, biological, or other single or combined processes to collect, purify, and regulate the water quality of various types of sewage, such as domestic sewage, industrial wastewater, and urban sewage, so that they meet discharge standards or reuse requirements. They are the core unit facilities of a wastewater treatment system.

[0003] Currently, the wastewater interception devices used in the influent stage of wastewater treatment ponds are mostly fixed structures. These are filter structures permanently installed in specific locations to intercept the wastewater entering the treatment pond. Through the interception effect of this fixed filter structure, objects that are too large or do not meet subsequent treatment requirements are trapped in the wastewater, achieving initial separation of wastewater and impurities. However, determining whether these fixed filter structures need cleaning to restore their interception performance mainly relies on regular manual inspections. But in the actual process of wastewater influent into the treatment pond, the wastewater flow velocity is not constant and is dynamically changed by various factors such as fluctuations in influent flow rate and changes in wastewater concentration. Differences in flow rate directly lead to varying rates of impurity adhesion and accumulation on the filter structure surface. This results in significant differences in the time it takes for the filter structure to reach the clogging threshold and require cleaning. In other words, the cleaning requirement for the filter structure is uncertain. When the water flow rate is high and the impurity accumulation rate is high, the filter structure may become clogged before the scheduled inspection period, leading to reduced interception efficiency, obstructed water flow, and disruption to subsequent wastewater treatment processes. Conversely, when the water flow rate is slow and the impurity accumulation rate is low, the filter structure may not become clogged but the scheduled inspection period may have already passed, resulting in a waste of manpower and time. Therefore, designing a new type of wastewater interception device for wastewater treatment ponds is a technical problem that engineers need to solve. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater interception device for wastewater treatment ponds to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A sewage treatment interception device for a sewage treatment tank includes a sewage treatment tank body. The sewage treatment tank body has an inlet end for discharging sewage at one end. A placement structure is located at the top of the sewage treatment tank body. An interception frame for filtering sewage is placed on the placement structure. A warning mechanism is fixedly installed on the side wall of the placement structure, and the warning mechanism and the interception frame are in a pressing fit. An auxiliary mechanism is fixedly installed on one side of the placement structure, and the auxiliary mechanism cooperates with the warning mechanism. The placement structure includes a placement frame positioned above the sewage treatment tank body. Mounting seats are fixedly installed at the four corners of the bottom end of the placement frame, and each mounting seat is rotatably connected to a caster wheel at its bottom end.

[0007] Furthermore, a limiting plate is fixedly installed on one side of each mounting base, and the limiting plate slides in conjunction with the side wall of the sewage treatment tank body. The setting of the limiting plate can restrict the position of the placement structure, further improving the stability of the device during operation.

[0008] Furthermore, the warning mechanism includes symmetrically arranged mounting slots on the placement frame. Each mounting slot at both ends of the placement frame has a slidingly connected mating plate. A penetrating plate is located below each mating plate and is fixedly installed within the mounting slot. An auxiliary spring is located between the mating plate and the penetrating plate and is installed within the mounting slot. Guide tubes are symmetrically fixedly installed at the bottom of the placement frame, with one end of each guide tube extending through the side wall of the placement frame into the mounting slot. Connecting tubes are fixedly installed at the ends of both guide tubes away from the placement frame, and a warning structure is fixedly installed at the end of one of the connecting tubes away from the guide tube.

[0009] As the amount of debris accumulated inside the interception frame gradually increases, the frame distributes its load evenly to the mating plate. By squeezing the mating plate, it simultaneously compresses the auxiliary spring and the hydraulic oil inside the mounting groove. The pressurized hydraulic oil is forced into the guide pipe through the penetration plate and then transported to the warning structure through the connecting pipe. This triggers the warning structure to issue an early warning to the staff. The downward movement of the interception frame under pressure occurs in two scenarios: First, a sudden increase in the amount of sewage intercepted by the frame within a short period causes the frame to move downward. Once the sewage flow returns to normal, the frame automatically resets and moves upward, preventing the warning mechanism from being falsely triggered. Second, as debris continues to accumulate inside the frame, the increased load pushes the frame downward, continuously compressing the hydraulic oil and triggering the warning mechanism, promptly alerting staff to clean the frame.

[0010] Furthermore, an annular support ring is provided at the bottom of the penetrating plate; several penetrating holes are equally spaced on the penetrating plate, and the penetrating holes are tapered holes, which are gradually narrowed along the fluid flow direction. The support ring at the bottom of the penetrating plate can provide stable support for the penetrating plate, and at the same time provide a reliable support foundation for the auxiliary spring, and reserve a receiving space at the bottom of the penetrating plate to reduce the obstruction of hydraulic oil flow, improve the smoothness of hydraulic oil penetration, and ensure smoother and more stable operation of the device. The penetrating holes on the penetrating plate adopt a tapered structure design, which can form a damping effect during the hydraulic oil flow process, avoid the hydraulic oil flow rate being too fast and causing impact on the warning mechanism, and play a protective role. At the same time, the damping effect slows down the hydraulic oil flow speed, further improving the stability of the device during operation.

[0011] Furthermore, mounting ears are fixedly installed on both sides of the top of the interception frame, and a pressing seat is fixedly installed at the center of the bottom of the mounting ears. The pressing seat and the mating plate are pressed together. The mounting ears and the pressing seat at the top of the interception frame can form a good fit with the mating plate. The two adopt a point contact fit, which can evenly distribute the load of the interception frame to the four mating plates. When the weight of the interception frame is tilted, the warning mechanism can achieve adaptive floating adjustment, avoiding false triggering of the warning mechanism due to uneven weight distribution of the interception frame, thereby effectively improving the smoothness and stability of the overall operation of the device.

[0012] Furthermore, the warning structure includes a mounting post fixedly installed at the end of the connecting pipe. A piston seat is slidably connected to the bottom of the mounting post. A plug seat is fixedly installed at the top of the piston seat. A mating seat is fixedly installed at the top of the mounting post, and the mating seat and the plug seat are electrically connected. A warning light is fixedly installed at the top of the mounting post, and the warning light is electrically connected to the mating seat.

[0013] As the amount of intercepted debris inside the interception frame gradually increases, the warning mechanism is activated simultaneously. The warning mechanism drives the corresponding warning structure to pressurize hydraulic oil into the mounting column and push the piston seat upward. As the piston seat moves upward, the plug seat and mating seat at its top become electrically connected, thereby triggering the warning light to illuminate, so as to alert the staff to clean the interception frame in time. At the same time, the system controls the valve at the water inlet to close, preventing the continuous water inlet from affecting the staff's work during the cleaning process.

[0014] Furthermore, the warning structure adopts a two-stage working mode: if the interception frame only intercepts a large amount of sewage impurities in a short period of time, the upward displacement of the piston seat is insufficient, the plug seat and the mating seat cannot achieve electrical connection, and the warning structure does not trigger the warning action; when the intercepted objects in the interception frame continue to accumulate and increase, the piston seat continues to move upward until the plug seat and the mating seat complete the electrical connection, the warning structure is activated and issues a cleaning warning to the staff.

[0015] Furthermore, the auxiliary mechanism includes an installation chamber fixedly installed at the end of the connecting pipe. Heat dissipation fins are fixedly installed at equal intervals on the outer surface of the installation chamber. A temperature measuring structure is fixedly installed at the top of the installation chamber, with its detection end extending into the interior of the installation chamber. Heating rods are symmetrically arranged on both sides of the temperature measuring structure, with their ends extending into the interior of the installation chamber. The temperature measuring structure and the heating rods are electrically connected. A connecting frame is symmetrically fixedly installed at the top of the installation chamber, and the connecting frame is fixedly connected to the side wall of the placement frame. Since wastewater treatment devices are typically deployed outdoors, where there are significant temperature differences between day and night and between seasons, to ensure… The smoothness and stability of the warning mechanism's operation require maintaining the internal hydraulic oil temperature within a preset threshold range to ensure reliable operation. Therefore, this device is equipped with an auxiliary mechanism for rapid hydraulic oil temperature regulation. When high-temperature hydraulic oil enters the installation chamber, rapid cooling can be achieved through the combined action of the installation chamber and the heat dissipation fins. When low-temperature hydraulic oil enters the installation chamber, the temperature sensing structure can collect and process the hydraulic oil temperature signal in real time, thereby controlling the heating rod to start heating operations, rapidly raising the temperature of the low-temperature hydraulic oil, and further improving the smoothness of the warning mechanism's operation.

[0016] Furthermore, the top of the installation chamber is provided with an installation plane for installing the temperature measuring structure and the heating rod. The top of the installation chamber forms an installation plane, which facilitates the assembly and fixing of the temperature measuring structure and the heating rod. At the same time, the installation plane can improve the sealing performance when the temperature measuring structure, the heating rod and the installation chamber are connected, thereby improving the overall installation safety of the device.

[0017] Furthermore, both the mounting chamber and the heat dissipation fins are made of the same thermally conductive material. When the high-temperature hydraulic oil enters the mounting chamber, the mounting chamber absorbs the heat of the hydraulic oil and quickly dissipates the heat outward through the heat dissipation fins, which are made of the same material, thereby achieving rapid cooling of the hydraulic oil. This ensures that the hydraulic oil is maintained within a suitable operating temperature range during operation, thus guaranteeing smoother and more stable operation of the warning mechanism.

[0018] Furthermore, both ends of the placement frame are fixedly installed with limiting seats, and plug rods are slidably connected to the limiting seats. The plug rods are plugged into the top of the sewage treatment tank body. In order to increase the stability of the device during use, the operator moves the device to the preset working position, and then inserts the end of the plug rod into the preset plug hole at the top of the sewage treatment tank body to restrict the position of the device, thereby making the device more stable during use. In addition, the setting of the limiting seats can restrict the plug rod, improving the restriction of the plug rod during use.

[0019] The technical solution provided by this invention may include the following beneficial effects:

[0020] In this example, the warning mechanism can distinguish between two working conditions: a short-term increase in sewage and continuous accumulation of intercepted materials. It only activates when the intercepted materials accumulate to the point where they need to be cleaned, effectively avoiding accidental triggering that could interfere with normal operations. Once activated, it not only promptly alerts staff to the cleaning process via warning lights but also simultaneously controls the valve at the inlet to close, preventing continuous water intake from hindering the cleaning process and significantly improving cleaning efficiency.

[0021] In this example, through the auxiliary mechanism, the heat conduction synergy design of the installation chamber and the heat dissipation fins can quickly cool down the high-temperature hydraulic oil. At the same time, relying on the linkage control of the temperature measuring structure and the heating rod, the low-temperature hydraulic oil can be heated in time, effectively solving the problem of hydraulic oil temperature imbalance caused by large temperature differences in outdoor environments. This ensures that the hydraulic oil is always maintained within a suitable working temperature range, thereby avoiding the impact of abnormal temperature on the hydraulic drive accuracy and smooth operation of the warning mechanism, and improving the adaptability and reliability of the warning mechanism and the entire sewage treatment interception device in complex outdoor environments.

[0022] In this example, with the auxiliary mechanism's hydraulic oil temperature regulation function, the damping buffer design of the conical penetration hole, and its own adaptive floating structure, the warning mechanism can easily cope with complex scenarios such as large outdoor temperature differences and uneven weight distribution of the interception frame. It can effectively resist the impact of excessive hydraulic oil flow rate or environmental changes, ensuring the long-term stable operation of itself and the entire sewage treatment interception device, and further enhancing the practicality and reliability of the device.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] The technical solution of the present invention (Embodiment 1) is described in detail below with reference to the accompanying drawings.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The sewage treatment interception device for the sewage treatment tank specifically includes: a sewage treatment tank body 1, an inlet end 2 for discharging sewage at the end of the sewage treatment tank body 1, a placement structure 3 at the top of the sewage treatment tank body 1, an interception frame 4 for filtering sewage placed on the placement structure 3, a warning mechanism 6 fixedly installed on the side wall of the placement structure 3, and the warning mechanism 6 and the interception frame 4 are in a pressing fit, an auxiliary mechanism 7 fixedly installed on one side of the placement structure 3, and the auxiliary mechanism 7 and the warning mechanism 6 cooperate with each other; the placement structure 3 includes a placement frame 8 set above the sewage treatment tank body 1, and mounting bases 9 are fixedly installed at the four corners of the bottom end of the placement frame 8, and the bottom ends of the mounting bases 9 are rotatably connected to the moving wheels 10.

[0039] See Figure 1 Each side of the mounting base 9 is fixedly equipped with a limiting plate 5, and the limiting plate 5 slides in conjunction with the side wall of the sewage treatment tank body 1. The setting of the limiting plate 5 can restrict the position of the placement structure 3, further improving the stability of the device during operation.

[0040] See Figure 3 , Figure 4 , Figure 5 and Figure 6The warning mechanism 6 includes mounting slots symmetrically opened on the placement frame 8. Each mounting slot at both ends of the placement frame 8 is slidably connected to a mating plate 13. A penetrating plate 14 is provided below the mating plate 13 and is fixedly installed in the mounting slot. An auxiliary spring 15 is provided between the mating plate 13 and the penetrating plate 14 and is installed in the mounting slot. A guide tube 16 is symmetrically fixedly installed at the bottom end of the placement frame 8, and one end of the guide tube 16 extends through the side wall of the placement frame 8 into the mounting slot. A connecting tube 17 is fixedly installed at the end of each of the two guide tubes 16 away from the placement frame 8. A warning structure is fixedly installed at the end of one of the connecting tubes 17 away from the guide tube 16.

[0041] As the amount of intercepted material inside the interception frame 4 gradually increases, the interception frame 4 distributes its load evenly to the mating plate 13. By squeezing the mating plate 13, it simultaneously compresses the auxiliary spring 15 and the hydraulic oil inside the mounting groove. The pressurized hydraulic oil is forced into the guide pipe 16 through the penetrating plate 14 and then transported to the warning structure through the connecting pipe 17, triggering the warning structure to issue a warning to the staff. The downward movement of the interception frame 4 under pressure is divided into two working conditions: First, the amount of sewage intercepted by the interception frame 4 increases sharply in a short period of time, causing the position of the interception frame 4 to move downward. After the sewage flow returns to normal, the interception frame 4 can automatically reset and move upward to avoid the warning mechanism 6 being triggered falsely. Second, the intercepted material inside the interception frame 4 continues to accumulate, relying on the increase in load to push the interception frame 4 to move downward continuously, continuously compressing the hydraulic oil and triggering the warning mechanism 6 to start, promptly reminding the staff to clean the interception frame 4.

[0042] See Figure 6 The bottom end of the penetrating plate 14 is provided with an annular support ring; several penetrating holes are equally spaced on the penetrating plate 14. The penetrating holes are tapered holes, and the tapered penetrating holes are gradually narrowed along the fluid flow direction. The support ring at the bottom end of the penetrating plate 14 can provide stable support for the penetrating plate 14, and at the same time provide a reliable support foundation for the auxiliary spring 15. It also reserves a space at the bottom end of the penetrating plate 14 to reduce the obstruction of hydraulic oil flow, improve the smoothness of hydraulic oil penetration, and ensure smoother and more stable operation of the device. The penetrating holes on the penetrating plate 14 adopt a tapered structure design, which can form a damping effect during the hydraulic oil flow process, avoid the hydraulic oil flow rate being too fast and causing impact on the warning mechanism 6, and play a protective role. At the same time, the damping effect slows down the hydraulic oil flow speed, further improving the stability of the device during operation.

[0043] See Figure 4Mounting ear plates 11 are fixedly installed on both sides of the top of the interception frame 4. A pressing seat 12 is fixedly installed at the center of the bottom of the mounting ear plate 11, and the pressing seat 12 and the mating plate 13 are pressed together. The mounting ear plate 11 and the pressing seat 12 at the top of the interception frame 4 can form a good fit with the mating plate 13. The two adopt a point contact fit, which can evenly distribute the load of the interception frame 4 onto the four mating plates 13. When the interception frame 4 is tilted, the warning mechanism 6 can realize adaptive floating adjustment, avoiding false triggering of the warning mechanism 6 due to uneven weight distribution of the interception frame 4, thereby effectively improving the smoothness and stability of the overall operation of the device.

[0044] See Figure 8 The warning structure includes a mounting post 18 fixedly installed at the end of the connecting pipe 17. A piston seat 19 is slidably connected to the bottom of the mounting post 18. A plug seat 20 is fixedly installed at the top of the piston seat 19. A mating seat 21 is fixedly installed at the top of the mounting post 18, and the mating seat 21 and the plug seat 20 are electrically connected. A warning light 22 is fixedly installed at the top of the mounting post 18, and the warning light 22 is electrically connected to the mating seat 21.

[0045] As the amount of intercepted material inside the interception frame 4 gradually increases, the warning mechanism 6 is activated simultaneously. The warning mechanism 6 drives the corresponding warning structure to press hydraulic oil into the mounting column 18 and push the piston seat 19 upward. As the piston seat 19 moves upward, the plug seat 20 and the mating seat 21 at its top are electrically connected, thereby triggering the warning light 22 to light up, so as to warn the staff to clean the interception frame 4 in time. At the same time, the system controls the valve at the water inlet 2 to close, so as to prevent the water inlet 2 from continuously entering during the cleaning process and affecting the staff's work.

[0046] The warning structure adopts a two-stage working mode: if the interception frame 4 only intercepts a large amount of sewage impurities in a short period of time, the upward displacement of the piston seat 19 is insufficient, the plug seat 20 and the mating seat 21 cannot achieve electrical connection, and the warning structure does not trigger the warning action; when the intercepted objects in the interception frame 4 continue to accumulate and increase, the piston seat 19 continues to move upward until the plug seat 20 and the mating seat 21 complete the electrical connection, the warning structure is activated and issues a cleaning warning to the staff.

[0047] See Figure 7The auxiliary mechanism 7 includes an installation chamber 23 fixedly installed at the end of the connecting pipe 17. Heat dissipation fins 24 are fixedly installed at equal intervals on the outer surface of the installation chamber 23. A temperature measuring structure 25 is fixedly installed at the top of the installation chamber 23, with its detection end extending into the interior of the installation chamber 23. Heating rods 26 are symmetrically arranged on both sides of the temperature measuring structure 25, with their ends extending into the interior of the installation chamber 23. The temperature measuring structure 25 and the heating rods 26 are electrically connected. A connecting frame 27 is symmetrically fixedly installed at the top of the installation chamber 23, and the connecting frame 27 is fixedly connected to the side wall of the placement frame 8. Since wastewater treatment devices are typically deployed outdoors, and outdoor environments have large temperature differences between day and night and between seasons, [further details needed]. To ensure the smooth and stable operation of the warning mechanism 6, the temperature of the hydraulic oil inside the warning mechanism 6 must be maintained within a preset threshold range to guarantee its reliable operation. Therefore, this device is equipped with an auxiliary mechanism 7 for rapid temperature regulation of the hydraulic oil. When hydraulic oil with a high temperature enters the installation chamber 23, rapid cooling can be achieved through the synergistic effect of the installation chamber 23 and the heat dissipation fins 24. When hydraulic oil with a low temperature enters the installation chamber 23, the temperature measuring structure 25 can collect the hydraulic oil temperature signal in real time and complete the signal processing, thereby controlling the heating rod 26 to start heating operations, achieving rapid temperature rise of the low-temperature hydraulic oil, and further improving the smoothness of the warning mechanism 6's operation.

[0048] It should be noted that the temperature measuring structure 25 can quickly measure the temperature of hydraulic oil, and the temperature measuring structure 25 is a mature existing hydraulic oil temperature measuring structure.

[0049] See Figure 7 The top of the installation chamber 23 is provided with an installation plane for installing the temperature measuring structure 25 and the heating rod 26. The top of the installation chamber 23 forms an installation plane, which facilitates the assembly and fixing of the temperature measuring structure 25 and the heating rod 26. At the same time, the installation plane can improve the sealing performance when the temperature measuring structure 25, the heating rod 26 and the installation chamber 23 are connected, thereby improving the overall installation safety of the device.

[0050] See Figure 7 The mounting chamber 23 and the heat dissipation fins 24 are both made of the same thermally conductive material. When the hydraulic oil with a high temperature enters the mounting chamber 23, the mounting chamber 23 absorbs the heat of the hydraulic oil and quickly dissipates the heat to the outside through the heat dissipation fins 24 which are made of the same material, thereby achieving rapid cooling of the hydraulic oil and keeping the hydraulic oil in a suitable working temperature range during operation, thus ensuring that the warning mechanism 6 operates more smoothly and stably.

[0051] See Figure 5Both ends of the frame 8 are fixedly installed with limiting seats 28. A plug rod 29 is slidably connected to the limiting seat 28, and the plug rod 29 is plugged into the top of the sewage treatment tank body 1. In order to increase the stability of the device during use, the operator moves the device to the preset working position, and then inserts the end of the plug rod 29 into the preset plug hole at the top of the sewage treatment tank body 1 to restrict the position of the device, thereby making the device more stable during use. In addition, the setting of the limiting seat 28 can restrict the plug rod 29 and improve the restriction of the plug rod 29 during use.
