Description

Technical Field

[0001] The invention relates to the technical field of sewage discharge, and in particular to green and environmentally friendly sewage discharge detection equipment. Background Art

[0002] Urban sewage is mostly silt, granular wastewater with high turbidity; turbid wastewater must be treated by sedimentation and filtration and tested to meet the standards before it can be discharged into nature. Urban sewage mainly contains a large amount of silt. Urban sewage is discharged into the sedimentation tank to precipitate the silt in the sewage. After pre-treatment in the sedimentation tank, the sewage enters the anaerobic digestion tank for hydrolysis and acidification. After biochemical treatment, the sewage flows to the secondary sedimentation tank. Under the condition of continuous ventilation, aerobic microorganisms can take in the adsorbed organic pollutants as nutrients for metabolism, part of which is used for their own growth and reproduction, and part of which is converted into carbon dioxide and water; in the process of sewage treatment, the treated sewage needs to be tested regularly, and the treated sewage can be discharged only after it passes the test.

[0003] For example, a Chinese utility model patent with authorization announcement number CN214374716U discloses an industrial wastewater discharge detection device, including a detection box, a water inlet pipe is arranged on the top of the detection box, a rotating motor is arranged on one side of the water inlet pipe, a water inlet cavity is arranged in the detection box, a detection cavity is arranged on one side of the water inlet cavity, a drainage cavity is arranged on the side of the detection cavity away from the water inlet cavity, a water outlet pipe is arranged on one side of the drainage cavity, and one end of the water outlet pipe passes through the detection box; drainage operation is performed by a drainage pump to increase the drainage pressure, and at the same time, a detection table can be used to detect data during detection, and data collection can be performed in real time, and data of a flowing water source can be collected and detected, a scraper is fitted and connected to the inner wall of the drainage cavity, and orderly drainage can be achieved during drainage, and when the rotating motor stops working, it can be ensured that sewage will not leak.

[0004] In view of the above-mentioned related technologies, the industrial wastewater discharge detection equipment uses a drainage pump to perform drainage operations, which can increase the drainage pressure. At the same time, the detection table can be used to detect data during the detection, and real-time data collection can be performed. However, it is impossible to directly know whether the inspection probe inside the detection chamber is in contact with the sewage. The detection data of a fully immersed detection probe is more accurate than that of an incompletely immersed detection probe. Summary of the invention

[0005] In order to improve the problem that it is impossible to directly know whether the inspection probe inside the detection chamber is in contact with sewage, the present application provides a green and environmentally friendly sewage discharge detection device.

[0006] This application provides a green and environmentally friendly sewage discharge detection device, which adopts the following technical solutions:

[0007] A green and environmentally friendly sewage discharge detection equipment comprises a measuring cylinder and a detection bracket arranged outside the measuring cylinder. A detection component is arranged inside the measuring cylinder. The detection component comprises a hollow float placed in the measuring cylinder, a detection probe installed at the bottom of the hollow float, and a tension sensor installed on the detection bracket near the side wall of the measuring cylinder; the hollow float slides on the inner side of the measuring cylinder, and a twisted wire is connected between the test end of the tension sensor and the hollow float.

[0008] By adopting the above technical solution, the existing sewage discharge equipment pours the sewage to be discharged into the measuring cylinder, and the sewage to be discharged is poured into the inside of the measuring cylinder from the bottom of the measuring cylinder until the hollow float floats up due to the sewage to be discharged. The data of the gravity change of the hollow float monitored by the tension sensor is used to determine whether the hollow float on the inner side of the measuring cylinder has slipped. If the gravity data of the hollow float changes, that is, the hollow float has slipped, it means that the detection probe is completely immersed in the sewage; at this time, the detection probe completely immersed in the sewage to be discharged can more accurately detect whether the sewage to be discharged meets the discharge standards.

[0009] If the hollow float slips, it means that the detection probe is completely immersed in the sewage; if the hollow float does not slip, it means that the detection probe is not completely immersed in the sewage. The detection data of a completely immersed detection probe is more accurate than that of an incompletely immersed detection probe. The tension sensor is used to determine whether the detection probe is completely immersed in the sewage.

[0010] Optionally, a wall washing component for cleaning the inner wall of the measuring cylinder is provided in the measuring cylinder, and the wall washing component includes a hollow ring fixed to the top of the measuring cylinder, and a plurality of water nozzles are provided at the bottom of the hollow ring with its own axis as the circumference, and the plurality of water nozzles are arranged downward to clean the inner wall of the measuring cylinder.

[0011] By adopting the above technical solution, after the test is completed, a plurality of water nozzles are provided at equal intervals in the circumferential direction with its own axis as the bottom of the hollow ring, and the water nozzles are used to clean the impurities attached to the inner wall of the measuring cylinder, so as to achieve the effect of cleaning the inner wall of the measuring cylinder.

[0012] Optionally, a wire washing component for cleaning the stranded wire is provided above the measuring cylinder, and the wire washing component includes an annular cylinder mounted on the top of the measuring cylinder, and a rotating ring rotatably installed on the inner periphery of the annular cylinder; a plurality of water sprinkling ports are provided on the inner circumference of the rotating ring, and the plurality of water sprinkling ports are all connected to the inner side of the annular cylinder, the stranded wire is passed through the inner side of the annular cylinder, and a water inlet end and a water outlet end are provided on the circumferential side of the annular cylinder.

[0015] By adopting the above technical solution, the guide rod is limited by the hollow cone sleeve, so that the guide rod drives the hollow float to slide along the vertical direction, and the shaking of the hollow float is avoided as much as possible to affect the detection of the detection probe.

[0016] Optionally, a driving component is provided in the annular cylinder, and the driving component includes a plurality of water baffles provided inside the annular cylinder, and the plurality of water baffles are fixedly installed on the circumferential side of the rotating ring, and the water inlet end and the water outlet end are arranged in parallel and face the same side of the annular cylinder.

[0017] By adopting the above technical solution, the cleaning liquid drives the rotating ring to rotate through the plurality of water baffles, and the cleaning liquid is discharged from the annular cylinder through the water outlet. The rotating rotating ring drives the plurality of water sprinkling ports to rotate, so that the plurality of water sprinkling ports can flush away impurities attached to the sides of the stranded wire.

[0018] Optionally, the inner circumference of the hollow cone sleeve is provided with a rod washing component for cleaning the guide rod, and the rod washing component includes a plurality of nozzles on the inner circumference of the hollow cone sleeve, a cavity is provided in the hollow cone sleeve, and the nozzle is connected to the cavity of the hollow cone sleeve.

[0020] Optionally, a wiping component for wiping the guide rod is provided on the top of the hollow conical sleeve, and the wiping component includes an annular flannel cloth fixed to the top of the hollow conical sleeve, the guide rod passes through the inner circumference of the annular flannel cloth, and the outer circumferential surface of the guide rod is fitted with the inner circumferential surface of the annular flannel cloth.

[0021] By adopting the above technical solution, the annular flannel cloth can wipe off the moisture and sewage foam on the surface of the guide rod, thereby keeping the surface of the guide rod clean and avoiding moisture erosion of the guide rod to the greatest extent possible, thereby shortening the service life of the guide rod.

[0022] Optionally, the hollow ring and the annular cylinder are connected via a water pipe, and a straight pipe is connected between the hollow cone sleeve and the annular cylinder.

[0023] By adopting the above technical solution, the cleaning liquid is first poured into the inner side of the annular cylinder through the water inlet end, then poured into the inner side of the hollow cone sleeve through the straight pipe, and then poured into the inner side of the hollow ring through the water pipe, and finally the cleaning liquid is discharged from the annular cylinder through the water outlet end, thereby achieving the effect of the circulation of the cleaning liquid.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Through the change of gravity of the hollow float monitored by the tension sensor, it is judged whether the hollow float is slipping inside the measuring cylinder; if the gravity data of the hollow float changes, that is, the hollow float is slipping, it means that the detection probe is completely immersed in the sewage; at this time, the detection probe completely immersed in the sewage to be discharged can more accurately detect whether the sewage to be discharged meets the discharge standards;

[0028] If the hollow float slips, it means that the detection probe is completely immersed in sewage; if the hollow float does not slip, it means that the detection probe is not completely immersed in sewage. The detection data of a completely immersed detection probe is more accurate than that of an incompletely immersed detection probe. The tension sensor is used to determine whether the detection probe is completely immersed in sewage.

[0029] 2. The cleaning liquid drives the rotating ring to rotate through the plurality of water baffles, and the cleaning liquid is discharged from the annular cylinder through the water outlet.

At this time, the cleaning liquid drives the rotating ring to rotate through a number of water baffles, and the cleaning liquid in the annular cylinder is discharged from the annular cylinder through the water outlet.

The existing sewage discharge equipment pours sewage into the measuring cylinder 11, and judges whether the hollow float 13 on the inner side of the measuring cylinder 11 slips by monitoring the gravity change of the hollow float 13 by the tension sensor 17.

[0041] Reference Figure 1 , 2 4. If the hollow float 13 slips, it means that the detection probe 15 is completely immersed in sewage; if the hollow float 13 does not slip, it means that the detection probe 15 is not completely immersed in sewage. The detection data of the detection probe 15 that is completely immersed is more accurate than that of the detection probe 15 that is not completely immersed. The tension sensor 17 is used to judge whether the detection probe 15 is completely immersed in sewage.

[0042] Reference Figure 1 , 2 4. A plurality of water sprinkling ports 24 are arranged at equal intervals in the circumferential direction with the axis of the rotating ring 23 as the axis, and the plurality of water sprinkling ports 24 are all connected to the annular cylinder 21. A water baffle 25 is arranged inside the annular cylinder 21 along the vertical direction, and a plurality of water baffles 25 are arranged in the circumferential direction of the axis of the annular cylinder 21, and the plurality of water baffles 25 are fixedly installed on the outer circumferential surface of the rotating ring 23. A water inlet 26 and a water outlet 27 are arranged on the outer circumferential surface of the annular cylinder 21, and the water inlet 26 and the water outlet 27 are arranged in parallel and face the same side of the annular cylinder 21. The cleaning liquid is poured into the inner side of the annular cylinder 21 through the water inlet 26, and the cleaning liquid pushes the rotating ring 23 to rotate through the plurality of water baffles 25, and the cleaning liquid in the annular cylinder 21 is discharged from the annular cylinder 21 through the water outlet 27.

[0043] Reference Figure 1 , 24. The rotating rotating ring 23 drives a plurality of water sprinkling ports 24 to rotate, so that the plurality of water sprinkling ports 24 can flush away impurities attached to the sides of the stranded wire 18. A hollow ring 19 is coaxially arranged on the top of the measuring cylinder 11, and the hollow ring 19 is fixed to the inner circumference of the measuring cylinder 11. A plurality of water spray nozzles 20 are arranged at equal intervals in the circumferential direction of the bottom of the hollow ring 19 with its own axis as the circumferential center, and the plurality of water spray nozzles 20 are arranged vertically downward, and the water spray nozzles 20 are used to clean away impurities attached to the inner wall of the measuring cylinder 11. The hollow ring 19 and the annular cylinder 21 are connected by a water pipe, and two guide rods 28 are fixed to the top of the hollow float 13 in the vertical direction, and the annular cylinder 21 is arranged between the two guide rods 28.

[0044] Reference Figure 1 , 5 6, the circumference of the two guide rods 28 is sleeved with a hollow cone sleeve 29, and the hollow cone sleeve 29 is a trumpet-shaped measuring cylinder 11 structure. A cavity is provided in the hollow cone sleeve 29, and a plurality of nozzles 30 are installed on the inner circumference of the hollow cone sleeve 29, and the nozzles 30 are connected to the cavity of the hollow cone sleeve 29, and the nozzles 30 are used to clean the impurities attached to the circumference of the guide rod 28. A straight-through pipe 31 is connected between the hollow cone sleeve 29 and the annular cylinder 21, and the cavity of the hollow cone sleeve 29 is connected to the annular cylinder 21. An annular flannel 32 is coaxially fixed to the top of the hollow cone sleeve 29, and the guide rod 28 passes through the inner circumference of the annular flannel 32 at this time, and the outer circumference of the guide rod 28 fits with the inner circumference of the annular flannel 32.

The change in the gravity of the hollow float 13 monitored by the tension sensor 17 is used to determine whether the hollow float 13 on the inner side of the measuring cylinder 11 has slipped. If the gravity of the hollow float 13 changes, that is, the hollow float 13 has slipped, it means that the detection probe 15 is completely immersed in the sewage; at this time, the detection probe 15 that is completely immersed in the sewage to be discharged can more accurately detect whether the sewage to be discharged meets the discharge standards.

[0047] The rotating rotating ring 23 drives the plurality of water sprinkling ports 24 to rotate, so that the plurality of water sprinkling ports 24 can wash away the impurities attached to the sides of the stranded wire 18. The cleaning liquid is poured into the cavity of the hollow cone sleeve 29 through the straight pipe 31, and the nozzle 30 is connected to the cavity of the hollow cone sleeve 29.
