Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality monitoring, specifically a monitoring and discharge device with water quality abnormality backflow function. Background Technology
[0002] In industrial wastewater treatment, COD (Chemical Oxygen Demand) and SS (Suspended Solids) are core indicators for assessing whether water quality meets standards, and their monitoring accuracy and emission control are directly related to environmental compliance. Currently, wastewater monitoring and emission devices on the market still have many shortcomings: most devices use a single detection unit, and if the detection module malfunctions, shutdown for maintenance and replacement is required, leading to monitoring interruptions and affecting the continuity of the wastewater treatment process; the surface of the detection tank is prone to adhering to impurities and suspended solids from wastewater, lacking an automatic cleaning mechanism, which significantly reduces detection accuracy over long-term use, and manual cleaning is costly; some devices lack flow stabilization and guiding structures, making it easy for wastewater to splash and flow at unstable speeds when entering the detection area, further interfering with the accuracy of the detection data; in addition, some devices have a delayed response to water quality exceeding standards during recirculation, failing to achieve seamless "monitoring-judgment-recirculation," posing a potential risk of illegal discharge.
[0003] Existing patent (CN213689595U) discloses an auxiliary device for monitoring the water quality of industrial wastewater, including a monitoring box. A monitor is installed in the upper part of the inner cavity of the monitoring box, and a protective cover is installed outside the monitor. A monitoring head is installed inside the monitoring box, and the upper end of the monitoring head passes through the protective cover and connects to the monitor. A control console and an alarm are fixedly installed on one outer wall of the monitoring box, and a connecting pipe is fixedly connected to the side of the monitoring box away from the control console. A water pump corresponding to the connecting pipe is fixedly installed on the side wall of the monitoring box. An anti-clogging box is fixedly connected to the end of the connecting pipe away from the monitoring box, and a water pumping pipe is fixedly connected to the lower end of the anti-clogging box. A pipe anti-clogging device is installed inside the anti-clogging box. This invention can effectively solve the problem of large particulate impurities in the wastewater clogging the connecting pipe during wastewater sampling and monitoring, thus affecting the normal use of the monitoring box. It also makes cleaning impurities inside the anti-clogging box relatively convenient. However, in practical use, this device only has a single detection device, which has significant operational limitations. Industrial wastewater treatment is often a continuous, 24 / 7 operation. A malfunction in a single monitoring device will directly disrupt water quality monitoring – making it impossible to obtain key wastewater indicators in real time or determine whether the wastewater meets standards. Blindly discharging wastewater could easily lead to environmental violations; shutting down for maintenance would interrupt the wastewater treatment process, increasing production delay costs. This lack of redundancy makes it difficult to handle unexpected failures, fails to meet the practical needs of continuous, accurate wastewater monitoring in industrial settings, and reduces the reliability and stability of the equipment. Utility Model Content
[0004] The purpose of this invention is to solve the problems of the above-mentioned devices, which only have a single detection device, and whose monitoring is interrupted when a fault occurs. This not only fails to meet the industrial demand for continuous monitoring around the clock, but also poses risks of environmental violations and production delays, as well as insufficient operational reliability.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A monitoring and discharge device with abnormal water quality backflow function includes a buffer tank. An inlet pipe is connected to the left side of the buffer tank, and a drain pipe is connected to the right side. An adjustment assembly is installed inside the buffer tank. The adjustment assembly includes an adjustment screw, which is fixed to the upper inner wall of the buffer tank via a bearing. A threaded block is threaded onto the surface of the adjustment screw. A first limiting block is welded to the upper end of the threaded block. A first traction rope is fixed to the lower right side of the threaded block, and a second traction rope is fixed to the lower left side of the threaded block. A second connecting plate is fixed to the end of the second traction rope. A second sliding post is located below the second traction rope, and a second fixed post is located inside the second sliding post. A first sliding post is located below the first traction rope, and a first fixed post is located inside the first sliding post.
[0007] As a further embodiment of this utility model: the end of the first traction rope is fixed with a first connecting plate, and the left end of the adjusting screw is keyed to the power output end of the motor.
[0008] As a further embodiment of this utility model: the threaded block forms a sliding structure with the buffer box through the first limiting block, and the inner wall of the buffer box is fixed with a first fixing post and a second fixing post.
[0009] As a further embodiment of this utility model: a first traction rope is provided in the surface groove of the first sliding column, and a second traction rope is provided in the surface groove of the second sliding column.
[0010] As a further embodiment of this utility model: a detection component is provided on the lower front side of the first connecting plate, the detection component includes a main detection box, the main detection box is detachably installed on the lower front side of the first connecting plate, and second limiting blocks are provided on the left and right sides of the first connecting plate. A spare detection box is detachably installed on the lower front side of the second connecting plate, and a counterweight is installed on the upper end of the main detection box.
[0011] As a further improvement of this utility model: a fixing plate is welded to the center of the inner wall of the buffer box, and a brush is installed on the upper end of the fixing plate, and a water guide plate is provided below the fixing plate.
[0012] As a further improvement of this utility model: an electromagnetic valve is installed at the end of the drain pipe, and a return pump is connected to one side of the drain pipe through a pipeline.
[0013] As a further improvement of this utility model: the left and right sides of the second connecting plate are also provided with second limiting blocks, and the upper end of the spare detection box is also equipped with a counterweight.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model uses a motor to drive the adjusting screw to rotate, which causes the threaded block to slide under the limit of the first limit block. Then, the first traction rope and the second traction rope pull the first connecting plate and the second connecting plate respectively. With the guide of the sliding groove of the first sliding column and the second sliding column, the up and down movement of the main detection box and the backup detection box can be precisely controlled, so as to realize the rapid disengagement of the fault detection box and the timely replacement of the backup box. The switching process does not require machine shutdown, ensuring the continuity of monitoring work and improving the stability of device operation.
[0016] 2. This utility model incorporates COD and SS online detection modules in the main and backup detection boxes. The uniform small holes on the surface ensure that the wastewater fully contacts the detection elements. The brush on the fixed plate automatically cleans surface impurities, reducing detection interference. At the same time, the solenoid valve is linked with the reflux pump. After receiving the detection signal, it opens the discharge when the standard is met and immediately closes and starts the reflux when the standard is exceeded, forming a complete closed loop of detection, judgment and treatment. This not only ensures the accuracy of water quality monitoring, but also eliminates the risk of illegal discharge from the source. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] like Figures 1 to 5 As shown, a detection and discharge device with abnormal water quality backflow function includes a buffer tank 1. An inlet pipe 2 is connected to the left side of the buffer tank 1, and a drain pipe 3 is connected to the right side. An adjustment assembly 4 is installed inside the buffer tank 1. The adjustment assembly 4 includes an adjustment screw 401, which is fixed to the upper inner wall of the buffer tank 1 by a bearing. A threaded block 403 is threaded onto the surface of the adjustment screw 401. A first limiting block 402 is welded to the upper end of the threaded block 403. A first traction rope 408 is fixed to the lower right side of the threaded block 403, and a second traction rope 409 is fixed to the lower left side of the threaded block 403. A second connecting plate 411 is fixed to the end of the second traction rope 409. A second sliding column 407 is provided below the second traction rope 409. The sliding column 407 has a second fixed column 405 inside, and the first sliding column 406 is located below the first traction rope 408. The first fixed column 404 is located inside the first sliding column 406. When the adjusting screw 401 is rotated, the threaded block 403 slides to the left along the adjusting screw 401 under the limiting action of the first limiting block 402, and simultaneously pulls the first traction rope 408 on the lower right side. The first traction rope 408 slides in the groove on the surface of the first sliding column 406 and pulls the first connecting plate 410, thereby driving the main detection box 501, which is detachably installed on its lower front side, to move upward until it is removed from the wastewater. The second traction rope 409 gradually loosens, and the spare detection box 502 gradually moves downward under the gravity of the counterweight block 505 and is immersed in the wastewater, ensuring that the detection work is uninterrupted.
[0026] Furthermore, a first connecting plate 410 is fixed to the end of the first traction rope 408, and the left end of the adjusting screw 401 is keyed to the power output end of the motor 412. The first connecting plate 410 moves upward under the constraint of the second limiting blocks 504 on both sides, and the second limiting blocks 504 limit it.
[0027] Furthermore, the threaded block 403 forms a sliding structure with the buffer box 1 through the first limiting block 402, and the inner wall of the buffer box 1 is fixed with the first fixing post 404 and the second fixing post 405. Under the limiting action of the first limiting block 402, the threaded block 403 can slide along the direction of the adjusting screw 401.
[0028] Furthermore, a first traction rope 408 is provided in the surface groove of the first sliding column 406, and a second traction rope 409 is provided in the surface groove of the second sliding column 407. The surface grooves of the first sliding column 406 and the second sliding column 407 limit the first traction rope 408 and the second traction rope 409 to prevent them from deviating during the sliding process.
[0029] Example 2
[0030] In addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0031] Furthermore, a detection component 5 is provided on the lower front side of the first connecting plate 410. The detection component 5 includes a main detection box 501, which is detachably installed on the lower front side of the first connecting plate 410. Second limiting blocks 504 are provided on the left and right sides of the first connecting plate 410. A spare detection box 502 is detachably installed on the lower front side of the second connecting plate 411. A counterweight 505 is installed on the upper end of the main detection box 501. Several uniform small holes are opened on the surface of both the main detection box 501 and the spare detection box 502. Wastewater flows into the interior through the small holes. The COD online detection module and SS online detection module built into both can perform real-time and accurate detection of key water quality parameters of wastewater.
[0032] Furthermore, a fixing plate 506 is welded to the center of the inner wall of the buffer box 1, and a brush 503 is installed on the upper end of the fixing plate 506. A water guide plate 509 is provided below the fixing plate 506. The brush 503 will clean the impurities attached to the surface of the main detection box 501 or the backup detection box 502 when they move, so as to avoid pollutants affecting the detection accuracy of the COD and SS online detection modules.
[0033] Furthermore, a solenoid valve 507 is installed at the end of the drain pipe 3, and a return pump 508 is connected to one side of the drain pipe 3 via a pipe. If the test results show that the COD and SS indicators meet the standards, the solenoid valve 507 at the end of the drain pipe 3 remains open, and the wastewater is discharged normally through the drain pipe 3. If the main detection box 501 or the backup detection box 502 detects that the water quality parameters exceed the standards, the solenoid valve 507 immediately closes.
[0034] Furthermore, second limit blocks 504 are also provided on the left and right sides of the second connecting plate 411, and a counterweight 505 is also installed on the upper end of the backup detection box 502. The counterweight 505 can help reduce the shaking of the main detection box 501 or the backup detection box 502 in the wastewater.
[0035] Working Principle: The combined wastewater discharged from the intermediate water tank enters the buffer tank 1 through the inlet pipe 2. The buffer tank 1 temporarily stores and stabilizes the flow of wastewater, creating stable conditions for subsequent COD and SS index testing. When the wastewater enters, the guide plate 509 directs it to the main detection tank 501, effectively reducing splashing. Both the main detection tank 501 and the backup detection tank 502 have several uniform small holes on their surfaces, through which the wastewater flows in. The built-in online COD and online SS detection modules in both tanks perform real-time and accurate detection of key water quality parameters of the wastewater. The counterweight 505 helps reduce shaking in the wastewater in the main detection tank 501 or the backup detection tank 502, ensuring detection stability. If the test results show that the COD and SS indexes are within the standard, the solenoid valve 507 at the end of the drain pipe 3 remains open, and the wastewater is discharged normally through the drain pipe 3. If the main detection tank 501 or the backup detection tank 502 detects... If the water quality parameters exceed the standard, the solenoid valve 507 immediately closes, and at the same time, the return pump 508, which is connected to the drain pipe 3 via a pipeline, starts to guide the abnormal wastewater in the buffer tank 1 back to the comprehensive wastewater equalization tank for further treatment. The entire process forms a closed-loop treatment mechanism of comprehensive wastewater collection, real-time dual-parameter detection, and automatic return of wastewater exceeding the standard. When the main detection box 501 malfunctions, the motor 412 is started, and its power output end drives the adjusting screw 401 to rotate. Under the limiting action of the first limiting block 402, the threaded block 403 slides to the left along the adjusting screw 401, simultaneously pulling the first traction rope 408 on the lower right side. The first traction rope 408 slides in the groove on the surface of the first sliding column 406 and pulls the first connecting plate 410. The first connecting plate 410 moves upward under the constraint of the second limiting blocks 504 on both sides, thereby driving the main detection box 501, which is detachably installed on its lower front side, to move upward until it is separated from the wastewater. During the leftward movement of the threaded block 403, the second traction rope 409 gradually loosens, and the standby detection box 502 gradually moves down and is immersed in wastewater under the gravity of the counterweight block 505, ensuring uninterrupted detection work. In addition, the brush 503 installed on the upper end of the fixing plate 506 will clean the impurities attached to the surface of the main detection box 501 or the standby detection box 502 when they move, avoiding contaminants from affecting the detection accuracy of the COD and SS online detection modules. The first fixing column 404 and the second fixing column 405 respectively provide fixed support for the first sliding column 406 and the second sliding column 407, ensuring the stable operation of the adjustment component 4.
