Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, and more specifically to an industrial wastewater detection device. Background Technology

[0002] With the rapid development of industry, the amount of wastewater discharged during industrial production is increasing year by year. If discharged directly without effective testing and treatment, it will cause serious harm to water resources, the environment, soil ecology, and human health. Therefore, accurate and efficient testing of water quality indicators (such as pH value, chemical oxygen demand (COD), and heavy metal ion content) in industrial wastewater has become a crucial link in industrial environmental protection and an important prerequisite for achieving wastewater discharge standards and ensuring ecological and environmental safety. Currently, industrial wastewater testing equipment is widely used in various industries such as chemical, metallurgical, printing and dyeing, and pharmaceutical. Its testing efficiency and data accuracy directly affect the formulation of wastewater treatment plans and the implementation of environmental supervision.

[0003] A search revealed that while existing industrial wastewater testing equipment can detect some wastewater indicators, there is still room for improvement in terms of equipment structure design and ease of use. Most existing equipment uses a fixed sampling structure, with the sampling tube and the equipment body typically assembled via threaded or flanged connections. After long-term use, the sampling tube is prone to corrosion and blockage by wastewater, requiring frequent replacement and maintenance. Traditional connection methods involve cumbersome disassembly and assembly processes, requiring specialized tools and taking a long time, which seriously affects the efficiency of testing work.

[0004] The shortcomings of existing technologies are as follows: First, the sampling tube is inconvenient to assemble and disassemble, resulting in low maintenance efficiency. The connection structure between the sampling tube and the main body of existing equipment is complex, requiring manual operation with special tools for assembly and disassembly. This significantly extends equipment downtime, reduces overall testing efficiency, and repeated assembly and disassembly can lead to wear on the connection interface, affecting the equipment's sealing performance. Second, the detection chamber is difficult to clean, which can affect detection accuracy. Existing equipment lacks an efficient automatic cleaning mechanism. After testing, residual wastewater impurities easily adhere to the inner wall of the detection chamber and the detection probes for pH, COD, and heavy metal ions. Manual cleaning is insufficient to completely remove residual contaminants, thus interfering with subsequent test data and causing deviations in test results, failing to meet the requirements for high-precision testing.

[0005] Therefore, there is a need to provide an industrial wastewater testing device to solve the problems mentioned above. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0038] The guiding mechanism includes two electric telescopic rods 702.

[0039] In this embodiment, as Figure 1-3 As shown, when the electric telescopic rod 702 is activated, it drives the base plate 704 and the spring rod 703 to rise and fall. The roller 706 at the top of the spring rod 703 can push the wedge block 708 to slide along the slide groove 804, thereby causing the slide plate 705 to drive the locking block 707 to disengage from or lock into the slot of the sampling tube 4. With the reset action of the compression spring 701, the fixing or disassembly of the sampling tube 4 is completed.

[0040] Example 2

[0041] The difference from Embodiment 1 is that this embodiment discloses that the mounting base assembly 8 includes a mounting base body 801, the top end of the mounting base body 801 is fixedly connected to the bottom end of the device body 1, square grooves 803 are provided on both sides of the bottom end of the mounting base body 801, and sliding grooves 804 are provided in the middle of the top of the two square grooves 803.

[0042] The stirring assembly 2 includes a protective shell 201. The bottom end of the protective shell 201 is fixedly connected to the middle of the top of the equipment body 1. A stirring motor 202 is fixedly connected to the middle of the protective shell 201. The transmission end of the stirring motor 202 passes through the equipment body 1 and is fixedly connected to a stirring rod 203. A limiting rod 6 is fixedly connected to the middle of the inner wall of the equipment body 1. The outer wall of the stirring rod 203 is movably sleeved with the middle of the limiting rod 6.

[0043] The cleaning component 3 includes a water tank 303, which is located on the right side of the equipment body 1. A support base 304 is fixedly connected to the bottom of the water tank 303. The left side of the support base 304 is fixedly connected to the bottom right side of the equipment body 1. A water outlet pipe 302 is fixedly connected to the left side of the water tank 303 near the top. The left end of the water outlet pipe 302 passes through the equipment body 1 and is fixedly connected to an annular high-pressure pipe 305. A sprayer 301 is fixedly connected to the inner wall of the annular high-pressure pipe 305. The sprayers 301 are arranged at an angle and staggered.

[0044] In this embodiment, as Figure 1-2 and Figure 4 As shown, the clean water in the water tank 303 is transported to the annular high-pressure pipe 305 through the water outlet pipe 302, and then forms a high-pressure spray water flow through the sprayers 301 arranged at an angle, which can clean the inner wall of the equipment body 1, the pH value probe 9, the COD detection probe 10 and the heavy metal ion detection probe 11 without dead angles.

[0045] The working principle of this utility model is as follows: Before industrial wastewater testing, wastewater sampling is first performed through the sampling tube 4. The sampling tube 4 is stably connected to the mounting base assembly 8 via the disassembly and assembly component 7. In the initial state, the compression spring 701 is in a naturally extended state, which pushes the wedge block 708 to move along the sliding groove 804 of the mounting base body 801 towards the sampling tube 4. The wedge block 708 drives the sliding plate 705 to move synchronously, so that the locking block 707 on the sliding plate 705 accurately engages in the locking groove on the outer wall of the sampling tube 4, thereby firmly fixing the sampling tube 4 in the mounting groove 802 of the mounting base body 801. The operator can control the flow rate and flow of wastewater entering the internal detection chamber of the equipment body 1 by adjusting the flow regulating valve 5 in the middle of the sampling tube 4 to ensure that the sampling volume meets the testing requirements. After the wastewater enters the internal detection chamber of the equipment body 1, the stirring component 2 is activated to uniformly mix the wastewater to ensure the accuracy of the test data. The stirring motor 202 of the stirring assembly 2 is installed inside the protective shell 201. After starting, the transmission end of the stirring motor 202 drives the stirring rod 203 to rotate. The stirring rod 203 rotates stably under the limiting action of the limiting rod 6, which fully stirs the sewage in the detection chamber to avoid uneven distribution of pollutants in the sewage affecting the detection results. The pH value probe 9, COD detection probe 10 and heavy metal ion detection probe 11 installed on the inner wall of the equipment body 1 work synchronously to detect key indicators such as pH value, chemical oxygen demand (COD) and heavy metal ion content of sewage in real time, and transmit the detection data to the external control system. After a single sewage test is completed, the cleaning assembly 3 is activated to clean the detection chamber inside the equipment body 1 and each detection probe to prepare for the next test. The water tank 303 of the cleaning component 3 stores cleaning water. Under water pressure, the cleaning water is transported through the outlet pipe 302 to the annular high-pressure pipe 305. The sprayers 301 on the inner wall of the annular high-pressure pipe 305 are arranged in an inclined and staggered manner, which can convert the cleaning water into a high-pressure spray flow to thoroughly rinse the inner wall of the equipment body 1, the pH value probe 9, the COD detection probe 10, and the heavy metal ion detection probe 11 without dead angles, effectively removing residual sewage impurities and pollutants. The cleaned sewage can be discharged from the equipment body 1 through the sampling pipe 4.
