Description

Technical Field

[0001] This utility model relates to the technical field of wastewater monitoring equipment, specifically to a device for monitoring industrial wastewater. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants lost with the water. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains various metals such as lead and cadmium; wastewater from the electroplating industry contains various heavy metals such as cyanide and chromium; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides.

[0003] Application number "CN202022248733.0" discloses an online wastewater monitoring device, including a wastewater monitoring tank. A set of inlet pipes and a set of outlet pipes are fixedly connected to the wastewater monitoring tank. A water quality detection port is provided on the top of the wastewater monitoring tank, and a water quality detection device is placed inside the water quality detection port. The water quality detection device can detect the wastewater quality and wirelessly transmit the detected water quality signal to a remote monitoring PC. A water quality sampling box is fixedly connected to one side of the wastewater monitoring tank near its bottom. A sampling bottle is snapped into the water quality sampling box. The wastewater monitoring tank and the sampling bottle are connected by sampling pipes, and a first-order electrically controlled valve is fixedly installed on the sampling pipes. A second-order electrically controlled valve is fixedly installed on the outlet pipe. This utility model has the advantages of remote real-time monitoring of wastewater quality, ensuring that discharge meets standards, and allowing for timed sampling. It is mainly used for wastewater quality detection.

[0004] The equipment in the relevant technology can only detect water layers at a corresponding depth, making it inconvenient to detect pH values ​​at different water layers. If staff want to obtain pH values ​​at different water depths, they often need to use tools such as long poles to extend the detection probe to different depths or to take samples from different water levels using samplers. This is difficult to operate and can easily lead to deviations in the test data due to hand shaking. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-5This utility model discloses an industrial wastewater monitoring device, comprising a treatment tank 1, a pH detection component, and a control box 11. The control box 11 is equipped with a display panel. The bottom of the treatment tank 1 is equipped with a drain pipe 2, and the drain pipe 2 is equipped with a valve. The pH detection component includes a top plate 3, a pH detection probe 18, a U-shaped limit frame 4, and a drive component. A first vertical pipe 17 is fixedly installed at the lower end of the top plate 3. A first slot 16 is provided inside the first vertical pipe 17. A second vertical pipe 13 is slidably installed in the first slot 16. A second slot 14 is provided inside the second vertical pipe 13. An inner pipe 15 is fixedly installed in the second slot 14. The inner pipe 15 is provided with an internal threaded groove. The drive component includes a motor 10 and a second threaded rod 12. The motor 10 is fixed at the upper end of the top plate 3. The top end of the second threaded rod 12 is connected to the output end of the motor 10. The second threaded rod 12 passes through the first slot 16 and is inserted into the internal threaded groove (the motor 10 has a motor shaft that passes through the top plate 3, and the top end of the second threaded rod 12 is connected to the bottom end of the motor shaft by a coupling).

[0026] The upper end of the U-shaped limiting frame 4 is fixedly provided with a limiting seat 5, the limiting seat 5 is installed on one side of the first vertical tube 17, and the U-shaped limiting frame 4 is installed on the top of the processing box 1.

[0027] The control box 11 is fixed to the upper end of the top plate 3, and the pH detection probe 18 is installed at the lower end of the second vertical pipe 13. The pH detection probe 18 and the control box 11 are connected by a wire, which passes through the second slot 14 and the first slot 16 in sequence.

[0028] Both the outer ends of the first threaded rod 8 and the locking rod 9 are provided with a toggle block.

[0029] Both the locking rod 9 and the outer end of the first threaded rod 8 are equipped with a toggle block, which facilitates manual operation and reduces the difficulty of adjustment.

[0030] Device installation and fixation:

[0031] The U-shaped limiting frame 4 is fastened to the top of the processing box 1. The U-shaped limiting frame 4 is provided with a locking rod 9. The locking rod 9 passes through the U-shaped limiting frame 4 and one end abuts against the outer wall of the processing box 1. The locking rod 9 is threadedly connected to the U-shaped limiting frame 4. The U-shaped limiting frame 4 and the limiting seat 5 are an integrated structure.

[0032] The U-shaped limiting frame 4 is fastened to the top of the processing box 1, so that the top of the side wall of the processing box 1 is embedded in the inner side of the U-shaped limiting frame 4. By moving the toggle block at the outer end of the locking rod 9, the locking rod 9 is rotated until one end of it presses against the outer wall of the processing box 1, thus completing the fixation of the U-shaped limiting frame 4 and the processing box 1. Since the U-shaped limiting frame 4 and the limiting seat 5 are an integrated structure, the limiting seat 5 is fixed synchronously with the U-shaped limiting frame 4.

[0033] Horizontal position adjustment:

[0034] A side plate 6 is fixedly installed on one side of the first vertical tube 17. Two support rods 7 that penetrate the limiting seat 5 are symmetrically arranged at both ends of the side plate 6. The support rods 7 are slidably connected to the limiting seat 5. A first threaded rod 8 that penetrates the limiting seat 5 is provided in the middle part of the side plate 6. The first threaded rod 8 is threadedly connected to the limiting seat 5. One end of the first threaded rod 8 is inserted into the limiting seat 5 and is rotatably connected to the limiting seat 5 through a bearing.

[0035] Move the actuating block at the outer end of the first threaded rod 8 to rotate the first threaded rod 8. Since the first threaded rod 8 is threadedly connected to the limiting seat 5 and one end is rotatably connected to the limiting seat 5 through a bearing, its rotation will drive the side plate 6 to move along the direction of the support rod 7 (the support rod 7 passes through the limiting seat 5 and is relatively fixed to the U-shaped limiting frame 4 integrated with it).

[0036] The side plate 6 is fixedly connected to the first vertical pipe 17. Therefore, the first vertical pipe 17 moves synchronously with the side plate 6, thereby driving the top plate 3 and the pH detection component installed at the lower end of the top plate 3 to move laterally as a whole, and finally adjusting the lateral distance between the pH detection probe 18 and the inner wall of the treatment box 1.

[0037] Depth adjustment and pH value detection:

[0038] Two rectangular blocks are symmetrically arranged on the outer wall of the second vertical tube 13. The rectangular blocks and the second vertical tube 13 are an integral structure, and the outer wall of the second vertical tube 13 and the rectangular blocks are tightly fitted with the inner wall of the first empty groove 16, so that the second vertical tube 13 will not rotate in the first empty groove 16.

[0039] The motor 10 is started by the control box 11, and the output end of the motor 10 drives the second threaded rod 12 to rotate.

[0040] The second threaded rod 12 passes through the first slot 16 inside the first vertical tube 17, and its lower end is inserted into the inner threaded groove of the inner tube 15 in the second slot 14 inside the second vertical tube 13, forming a threaded drive.

[0041] Because the outer wall of the second vertical tube 13 is symmetrically provided with rectangular blocks, and the rectangular blocks are integrated with the second vertical tube 13, their outer walls are tightly fitted with the inner wall of the first empty groove 16, which restricts the rotation of the second vertical tube 13, allowing it to only move up and down along the axial direction of the first empty groove 16, thereby driving the PH detection probe 18 at the lower end to adjust its depth in the processing box 1.

[0042] The pH detection probe 18 transmits the detected pH value information to the control box 11 via a wire (the wire passes through the second empty slot 14 and the first empty slot 16 in sequence to avoid direct contact with wastewater), and finally displays it in real time on the display panel of the control box 11.

[0043] Wastewater discharge:

[0044] After the test is completed, the wastewater in the treatment tank 1 can be discharged through the drain pipe 2 by opening the valve on the drain pipe 2 at the bottom of the treatment tank 1.

[0045] The rectangular block on the outer wall of the second vertical tube 13 fits tightly against the inner wall of the first empty groove 16, effectively preventing the second vertical tube 13 from rotating or shaking when it is raised or lowered, and avoiding deviations in detection data caused by probe shaking.

[0046] The pH detection probe 18 is connected to the control box 11 via a wire, ensuring stable data transmission. Combined with real-time feedback from the display panel, the detection results are intuitive and reliable.

[0047] The U-shaped limit bracket is quickly fixed to the top of the processing box 1 by the locking rod 9, making installation and disassembly convenient.

[0048] The second vertical pipe 13 fits tightly with the first empty slot 16, reducing the gap between the second vertical pipe 13 and the first empty slot 16, which can effectively prevent wastewater from seeping into the interior of the first empty slot 16 and avoid corrosion of the internal transmission structure; the wire passes through the second empty slot 14 and the first empty slot 16, isolating it from wastewater and extending the service life of the line.

[0049] Motor 10 Selection:

[0050] Considering that the device may be located in a humid and somewhat corrosive industrial wastewater monitoring environment, a motor 10 with an IP65 protection rating was selected. It possesses excellent dust and water resistance, effectively preventing dust and splashes of water from entering the motor 10, protecting it from wastewater mist corrosion, and extending its service life.

[0051] Insulation class: The ambient temperature of industrial wastewater treatment is usually not too high, but in order to ensure the safety and stability of motor 10 during long-term operation, motor 10 with insulation class F is selected. It allows a temperature rise of 155℃, which can meet the heat dissipation requirements of general industrial environment and ensure the stable operation of motor 10.

[0052] Control box 11-body selection:

[0053] Protection Performance: Given the potential for corrosive gases and liquid splashes in industrial wastewater monitoring environments, the control box 11 must possess excellent corrosion and explosion-proof performance. A stainless steel control box 11, such as 304 stainless steel, can be selected, as it has strong corrosion resistance and can effectively resist the erosion of corrosive substances generated by wastewater. Simultaneously, the protection rating should reach IP65 or higher to ensure that internal electrical components are not affected by the external environment and to guarantee the stable operation of the control box 11.

[0054] Internal component configuration: An internal controller, such as a PLC (Programmable Logic Controller), is required to precisely control the operation of motor 10. Its flexible programming allows for accurate control of motor 10, meeting the needs of different depth detection by the pH detection probe 18. Overload protection components, such as thermal relays, should also be provided. A suitable current value should be set (e.g., 1.1-1.25 times the rated current of motor 10). When motor 10 experiences overload, the circuit should be promptly cut off to protect motor 10 and other equipment. A display panel, such as an LCD screen, is required for real-time display of pH detection data. Its clear display provides a clear and intuitive presentation of the test results, facilitating easy reading by operators.

[0055] pH detection probe selection 18:

[0056] Measurement range: The pH value of industrial wastewater is usually between 2 and 12. Select a pH detection probe with a measurement range covering this range, such as a detection probe with a measurement range of 0-14, to ensure accurate measurement of the acidity and alkalinity of various industrial wastewaters and meet the different wastewater detection needs.

[0057] Accuracy: To ensure the accuracy of the detection data, a high-precision pH detection probe 18 was selected, with an accuracy of ±0.01 pH. This high-precision probe provides a reliable basis for subsequent wastewater treatment, helping operators to more accurately assess the wastewater treatment status.

[0058] Material: Considering the corrosiveness of industrial wastewater, the detection probe should be made of corrosion-resistant material, such as glass electrode material, which has good chemical stability, can work stably in a variety of corrosive wastewater, is not easily corroded by wastewater, and ensures the service life and detection accuracy of the detection probe.

[0059] Ease of maintenance: Select a pH detection probe 18 that is easy to maintain and calibrate. If the probe has an automatic calibration function, manual operation can be reduced and detection efficiency can be improved.
