Description

Technical Field

[0001] The invention relates to the technical field of wastewater detection, in particular to a wastewater discharge detection device for environmental detection. Background Art

[0002] Testing wastewater before it is discharged is one of the important means of environmental protection. Through testing, water pollution can be discovered in a timely manner, and the composition and content of harmful substances in wastewater can be understood, so that corresponding treatment measures can be taken to prevent excessive wastewater from being discharged into rivers, lakes and other natural water bodies, and to protect the ecological environment and biodiversity of water bodies. Wastewater testing can also provide guidance for the design, operation and maintenance of sewage treatment facilities, improve sewage treatment efficiency and water quality compliance rate. At the same time, testing can discover useful components in wastewater, realize resource recovery and reuse, and reduce environmental pollution.

[0003] In the prior art, the solutions for detecting wastewater discharge during environmental testing include electrochemical detection, optical detection, chemical reagent detection and other solutions. Among them, the optical detection solution mainly detects the scattering phenomenon generated when the light source penetrates the sewage, and the turbidity value of the wastewater can be determined by measuring the transmittance of the transmitted light.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a wastewater discharge detection device for environmental detection, comprising a detection device body, the detection device body comprising a detection box 1, a first cleaning component 15 and a second cleaning component 16, the bottom of the detection box 1 is integrally formed with a discharge box 3, one side of the discharge box 3 is screwed with a slag discharge cover plate 4, the surface of the detection box 1 is screwed with a motor 5, the output end of the motor 5 is inserted with a drive shaft 10, the surface of the drive shaft 10 is welded with a fixed sleeve 11, and the side of the fixed sleeve 11 is integrally formed with a bending rod 12, the number of the bending rods 12 is two, and the end of each bending rod 12 is installed with a light source module 13 or a photoelectric receiving module 14, the surface of the driving shaft 10 is also welded with a second cleaning component 16, and the edge of the second cleaning component 16 is in contact with the inner wall of the detection box 1, and the end of the driving shaft 10 is embedded in the inner wall of the detection box 1 through a bearing, and the detection box 1 is provided with a detection cavity 18, and the discharge box 3 is provided with a slag discharge cavity 19, and the interior of the detection cavity 18 is connected to the interior of the slag discharge cavity 19. The wastewater discharge detection device for environmental detection is used to detect the turbidity of the injected wastewater sample.

[0029] When the present invention is used, the wastewater to be tested is transported to the inside of the detection box 1 through the injection pipe 2 on the side, and then the motor 5 on the side is started. The motor 5 drives the driving shaft 10 to rotate, and the two bending rods 12 can be used to drive the dynamic light source module 13 and the photoelectric receiving module 14 at the end to rotate from the bottom of the wastewater to be tested to the top, and the dynamic light source module 13 and the photoelectric receiving module 14 are used to detect the wastewater to be tested. During the detection, the turbidity is determined by the intensity of the measurement light emitted by the light source module 13 through the wastewater to be tested, and the photoelectric receiving module 14 is used to receive the projected light. The higher the turbidity, the lower the intensity of the transmitted light. In this way, the purpose of detecting the turbidity of the wastewater is achieved, wherein the light source module 13 and the photoelectric receiving module 14 are both existing mature technologies and do not belong to the protection scope of the present invention, so their specific structure and calculation principle are not described here. By controlling the light source module 13 and the photoelectric receiving module 14 to continuously rotate upward through the above-mentioned structure, the turbidity of the wastewater to be tested at different heights can be detected, and after the detection is completed, the bottom valve 9 is opened to discharge the wastewater to be tested toward the bottom of the discharge box 3. At the same time, the light source module 13 and the photoelectric receiving module 14 are controlled by the motor 5 to continue to move upward, and the first cleaning component 15 is cooperated to achieve the cleaning purpose of the light source module 13 and the photoelectric receiving module 14, and then the second cleaning component 16 is rotated downward to achieve the cleaning effect of the inner wall of the detection cavity 18.

[0030] In this embodiment, a flushing hole 33 is provided on the top of the detection box 1, a guide channel 7 is welded on the outside of the flushing hole 33, a flushing pipe 6 is inserted on the side of the guide channel 7, and the flushing pipe 6 is connected to the external high-pressure water pump through a water pipe. The side of the detection box 1 is also connected to the injection pipe 2, a partition 35 is welded on the bottom of the detection cavity 18, and a slag discharge interlayer 34 is provided on one side of the top of the partition 35, and a concentration hole 36 is provided on the side of the slag discharge interlayer 34 and the side of the slag discharge cavity 19. A slag discharge pipe 8 is inserted on the outside of the concentration hole 36, a valve 9 is installed on the surface of the slag discharge pipe 8, and the slag discharge interlayer 34 and the slag discharge cavity 19 are separated by a partition 35, and the slag discharge interlayer 34 and the slag discharge cavity 19 are connected to each other through the slag discharge pipe 8. By driving the light source module 13 and the photoelectric receiving module 14 to rotate along the arc-shaped detection cavity 18 through the motor 5, the light source module 13 and the photoelectric receiving module 14 can be moved to different depth positions in the detection cavity 18, so as to detect and process the turbidity of the wastewater at different depths, and then obtain effective data that can reflect the overall turbidity of the wastewater.

[0031] Specifically, after starting the motor 5, the motor 5 directly drives the fixed sleeve 11 to rotate through the driving shaft 10, and one end of the two bending rods 12 is partially integrated with the fixed sleeve 11, so the bending rod 12 can drive the light source module 13 and the photoelectric receiving module 14 at the end to move synchronously, and the light source module 13 and the photoelectric receiving module 14 are both installed inside the detection sleeve 26, and the light source module 13 is irradiated toward the photoelectric receiving module 14 through the light-transmitting plate 27 on the side of the detection sleeve 26, so as to detect the turbidity of the wastewater to be tested between the light source module 13 and the photoelectric receiving module 14, and the two detection sleeves 26 always remain in a parallel state.

[0032] In this embodiment, the second cleaning component 16 includes a side scraper 20 and a shovel plate 21. One end of the side scraper 20 is welded and fixed to the driving shaft 10. The shovel plate 21 is integrally formed at the end of the side scraper 20. The side of the shovel plate 21 is against the arc plate area inside the detection cavity 18, and the side of the side scraper 20 is against the vertical surface of the inner wall of the detection cavity 18. The surface of the side scraper 20 is provided with a guide groove 22. A through hole 23 is provided at one end of the guide groove 22, and the through hole 23 is used to discharge the wastewater inside the guide groove 22 toward the bottom. The second cleaning component 16 encloses the bending rod 12, the light source module 13 and the photoelectric receiving module 14 on the inside. After completing the detection of the turbidity of the wastewater at different depths, the second cleaning component 16 can be used to clean the inner wall of the detection box 1 to prevent the impurities of the batch of wastewater samples from adhering to the inner wall of the detection cavity 18, thereby interfering with the detection results of subsequent batches of wastewater samples.

[0033] Specifically, after completing the detection of the batch of wastewater samples, first open the bottom valve 9 to discharge the wastewater inside the detection cavity 18 into the bottom discharge box 3 along the bottom focusing hole 36 and the slag discharge pipe 8, and then start the motor 5, and move the second cleaning component 16 on the side downward to achieve the purpose of cleaning the inner wall of the detection cavity 18. In this process, the arc-shaped inner wall and the vertical inner wall of the detection cavity 18 are scraped by rotating the side scraper 20 and the shovel plate 21, and the scraped residue is directly dropped to the bottom. When the second cleaning component 16 rotates toward the top, it can flush clean water into the interior of the detection box 1 along the flushing pipe 6, the guide channel 7 and the flushing hole 33, and impact the shovel plate 21 and the side scraper 20, and directly discharge the residue to the area near the slag discharge interlayer 34 along the guide groove 22 and the through hole 23. At the same time, the flushed clean water is also used to directly clean the surface of the light source module 13 and the photoelectric receiving module 14.

[0034] In this embodiment, the end of the bending rod 12 is integrally formed with a support column 24, and the first cleaning component 15 is inserted into the interior of the support column 24. The first cleaning component 15 includes a rear end plate 30 and a sliding sleeve 28. A detection sleeve 26 is fixed to the side of the support column 24, and a light-transmitting plate 27 is embedded in the side of the detection sleeve 26. The light source module 13 or the photoelectric receiving module 14 is installed in the detection sleeve 26, and the telescopic rod 25 is inserted into the interior of the support column 24. The rear end plate 30 and the sliding sleeve 28 are welded to the two ends of the telescopic rod 25 respectively. The outer side of the rear end plate 30 is embedded with a ball 32. The sliding sleeve 28 is sleeved on the surface of the detection sleeve 26, and the two ends of the sliding sleeve 28 are integrally formed with scrapers 29. A spring 31 is connected to the inner side of the rear end plate 30, and the other end of the spring 31 is welded to the surface of the support column 24. The inner wall of the detection box 1 is integrally formed with a corrugated plate 17, and the rear end plate 30 is pressed against the surface of the corrugated plate 17 through a ball 32. After the wastewater detection is completed by the light source module 13 and the photoelectric receiving module 14, as the driving mechanism controls the upward movement of the modules, the first cleaning component 15 on the light source module 13 and the photoelectric receiving module 14 can be triggered in cooperation with the corrugated plate 17, and the first cleaning component 15 is used to realize the cleaning process of the surface of the light source module 13 and the photoelectric receiving module 14. The whole cleaning process is efficient and convenient, and it can also cooperate with the second cleaning component 16 for additional rinsing treatment, further enhancing the cleaning effect.

[0035] Specifically, when the light source module 13 and the photoelectric receiving module 14 have completed the detection, as the driving shaft 10 drives the bending rod 12 to continue to rotate toward the top, the rear end plate 30 can be pressed against the surface of the corrugated plate 17. At this time, the spring 31 can be controlled to be compressed by the corrugated plate 17, and the sliding sleeve 28 at the other end is also controlled by the telescopic rod 25 to move along the surface of the detection sleeve 26, and then the surface of the detection sleeve 26 is scraped and cleaned by the scraper 29, thereby achieving the purpose of cleaning impurities attached to the surface of the detection sleeve 26.
