Description

[0001] This case is a divisional application of the invention name "A production supervision method based on pipeline flow in electroplating centralized control area", application date "2021 / 3 / 16", "2021102828280". Technical Field

[0002] The present invention relates to wastewater treatment technology, in particular to wastewater treatment management in the electroplating industry, and more specifically to an installation structure and method for an electroplating wastewater recording sensor in an electroplating centralized control area. Background Art

[0003] The wastewater output of the electroplating industry is less than that of the papermaking, printing and dyeing, and chemical industries. However, due to the wide distribution of electroplating plants, there are many types of harmful substances contained in electroplating wastewater. Therefore, the treatment of electroplating wastewater is very important. Electroplating wastewater mainly contains heavy metal ions such as chromium, zinc, copper, lead, nickel, and cyanide, which is easily carcinogenic. If these substances are directly discharged into nature, on the one hand, they will cause great pollution to the environment and seriously threaten the life safety of animals and plants. On the other hand, the heavy metal ions in electroplating wastewater can be reused after recycling, and direct discharge will cause a waste of resources.

[0004] At present, the treatment of electroplating wastewater is either to treat one or two substances, or to treat all substances in a mixed way. The sewage treatment system that treats one or two electroplating wastewaters cannot cope well with the situation of multiple types of sewage. The system that treats all electroplating wastewaters equally often leads to poor treatment effects due to its lack of targeting.

[0005] In the existing environmental risk management of the electroplating industry, standardized park construction management is adopted. Professional electroplating plants are multi-story buildings to increase the building land volume ratio and building density. The first floor is used for warehousing and comprehensive office. Light and small-quantity plating types are placed on higher floors, while large-quantity and heavy-quality plating types should be arranged on lower floors. Wastewater collection rooms and collection troughs are set up according to wastewater classification and collection to facilitate screening of water quality causes. After preliminary filtration and sedimentation, gravity is used to discharge the wastewater into the trench. The trench can realize the function of no leakage of inspection, maintenance, and accidental wastewater, thereby eliminating the risk of environmental pollution.

[0006] In addition, since electroplating wastewater contains multiple substances such as chromium, zinc, copper, lead, and nickel, the treated water needs to be discharged into nature through different pipelines. When and how much to discharge involves both the production control of the electroplating industry and the control of the electroplating industry by the supervisory and management departments, which are often the two conflicting parties.

[0007] The heavy metal ions such as chromium, zinc, copper, lead, and nickel mentioned above are directly discharged into nature through gravity, that is, there is no measurement and detection at the export, or no measurement and detection equipment is installed. Therefore, the emission volume or the production process involved is not controlled in the last link, which brings trouble to the supervision and management departments' control over electroplating enterprises.

DETAILED DESCRIPTION

[0027] like Figure 1 , Figure 2 , Figure 3-1 , Figure 3-2 , Figure 4As shown, a production supervision method based on the pipeline flow in the electroplating centralized control area is formed by connecting and fixing an upper and lower discharge pipeline 1 by an upper interlayer pipe rack 2, a lower interlayer pipe rack 3, and upper and lower interlayer pipe rack support columns 4; the upper and lower interlayer pipe rack support columns 4 are spaced apart in the horizontal direction so that the discharge pipelines 1 of different wastewater discharge water are fixed in the intervals, and each discharge pipeline 1 of different wastewater discharge water is clamped and fixed by a discharge pipeline fixing clamping frame 5, which is characterized in that: a fluid flow sensing unit 6 is sleeved and fixed on the upper and lower interlayer pipe rack support columns 4, and the fluid flow sensing unit 6 includes an upper pipeline fluid sensor 6-1 and a lower pipeline fluid sensor 6-2, and the upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2 are respectively used to detect the flow status of the fluid in the upper pipeline and the lower pipeline, and send the flow status information of the fluid in the upper pipeline and the lower pipeline to the processing unit, and the processing unit obtains the time of wastewater treatment corresponding to the upper pipeline and the lower pipeline and the flow corresponding to the time.

[0028] The upper pipeline fluid sensor 6 - 1 is fixed to the bottom of the upper pipeline and is elastically connected to the bottom of the upper pipeline 1 .

[0029] The lower pipeline fluid sensor 6-2 is fixed on the top of the lower pipeline and is suspendedly connected to the top of the lower pipeline.

[0030] like Figure 3-1 As shown, the upper pipeline fluid sensor 6-1 includes: a spherical support 6-1-1, a fixed bracket 6-1-2, a spring 6-1-3, a spring fixing frame 6-1-4, a strain resistor 6-1-5, and an upper pipeline fluid detection processing circuit 6-1-6. The upper end of the spherical support 6-1-1 is elastically contacted and connected with the bottom of the upper pipeline 1-1, and the lower end of the spherical support 6-1-1 is fixed to the upper end of the fixed bracket 6-1-2 by a spring 6-1-3. There is a spring fixing frame 6-1-4 in the fixed bracket 6-1-2, and the bottom of the spring 6-1-3 acts on the upper surface of the spring fixing frame 6-1-4. There is a strain resistor 6-1-5 on the lower surface of the spring fixing frame 6-1-4, and the strain resistor 6-1-5 is electrically connected to the upper pipeline fluid detection processing circuit 6-1-6.

[0031] During operation, the fluid discharges liquid through the discharge pipe 1, thereby causing micro-vibration in the discharge pipe 1. This micro-vibration is reflected to the strain resistor 6-1-5 through the spherical support 6-1-1, the fixed bracket 6-1-2, the spring 6-1-3, and the spring fixing bracket 6-1-4. The strain resistor 6-1-5 outputs an electrical signal with amplitude and frequency changes. The electrical signal with amplitude and frequency changes output by the strain resistor 6-1-5 is processed by the upper pipeline fluid detection processing circuit 6-1-6 and transmitted to the host computer through the communication network. The host computer records and processes it at any time and notifies the relevant management personnel to determine whether the pipeline corresponding to this position belongs to chromium, zinc, copper, lead, or nickel, so as to realize the control of the wastewater treatment time and the corresponding flow rate.

[0032] This type of fluid detection does not require accurate flow data, and uses a structure that contacts but does not require construction on the pipeline, which can make the installation and construction process simple and convenient.

[0033] like Figure 3-2 As shown, the lower pipeline fluid sensor 6-2 includes: a cavity sphere 6-2-3, a spherical lens 6-2-4, a four-quadrant photoelectric sensor 6-2-6, a vibration sensing contact surface 6-2-5, a fluid sensing control unit 6-2-1, a light-emitting tube 6-2-2, a second support rod 7 and a first support rod 8. The second support rod 7 and the first support rod 8 are connected to the upper and lower interlayer pipe rack support columns 4 at one end and one end respectively. The other end (lower end) of the first support rod 8 is connected to the top of the cavity sphere 6-2-3. One end of the second support rod 7 is supported on the first support rod 8. The second support rod 7, the first support rod 8 and the upper and lower interlayer pipe rack support columns 4 form a triangular structure connection. The cavity sphere 6-2-3 is suspended on the discharge pipeline 1 fixed to the lower interlayer pipe rack; the cavity The vibration sensing contact surface 6-2-5 at the lower end of the sphere 6-2-3 is in dynamic contact with the top of the discharge pipe 1; a fluid sensing control unit 6-2-1 is fixed in the top cavity of the hollow sphere 6-2-3, and the fluid sensing control unit 6-2-1 is electrically connected to a light-emitting tube 6-2-2, and the light-emitting head of the light-emitting tube 6-2-2 emits light vertically downward toward the center of the cavity; a spherical lens 6-2-4 is provided at the bottom of the cavity of the hollow sphere 6-2-3, and a four-quadrant photoelectric sensor 6-2-6 is provided at the lower end of the spherical lens 6-2-4. In a stable state, the light-emitting head of the light-emitting tube 6-2-2 emits light vertically downward toward the center of the cavity, and is projected onto the four-quadrant photoelectric sensor 6-2-6 after passing through the spherical lens 6-2-4, and a stable signal is obtained by the four-quadrant photoelectric sensor 6-2-6.

[0034] During operation, the fluid discharges liquid through the discharge pipe 1, thereby causing micro-vibration in the discharge pipe 1. This micro-vibration will affect the vibration of the cavity sphere 6-2-3, thereby causing the spherical lens 6-2-4 to roll in the cavity sphere 6-2-3. When the light-emitting head of the light-emitting tube 6-2-2 emits light vertically downward toward the center of the cavity, it will not stably project light on the four-quadrant photoelectric sensor 6-2-6. The four-quadrant photoelectric sensor 6-2-6 will output a signal that changes with the vibration frequency and amplitude. The electrical signal with amplitude and frequency changes output by the four-quadrant photoelectric sensor 6-2-6 is processed by the fluid sensing control unit 6-2-1 and transmitted to the host computer through the communication network. The host computer will record and process it at any time and notify the relevant management personnel to determine whether the pipeline corresponding to this position belongs to chromium, zinc, copper, lead, or nickel, so as to realize the control of the wastewater treatment time and the flow rate corresponding to the time.

[0035] This type of fluid detection does not require accurate flow data, and uses a structure that contacts but does not require construction on the pipeline, which can make the installation and construction process simple and convenient.

[0036] like Figure 4 As shown, the lower pipeline fluid sensor 6-2 may include a pair, which are symmetrically fixed on both sides of the upper and lower barrier pipe rack support columns 4, and are simultaneously suspended on the left and right discharge pipelines 1 fixed on the lower barrier pipe rack.

[0037] like Figure 5 As shown, a schematic diagram of the signal output by the strain resistor 6-1-5 or the four-quadrant photoelectric sensor 6-2-6 detected by the upper pipeline fluid sensor 6-1 or the lower pipeline fluid sensor 6-2 at different times is given. In the figure, there are output signals in the time period 0-t1, the time period t2 to t3, and the time period t4 to t5, but the signal strengths are different in different time periods, indicating that the flow values ​​are different. However, it can be shown that there is flow flowing through the corresponding discharge pipeline 1, and the corresponding wastewater treatment process is working.

[0038] The discharge pipeline 1 is either a chromium-treated water discharge pipeline, a zinc-treated water discharge pipeline, a copper-treated water discharge pipeline, a lead-treated water discharge pipeline, or a nickel-treated water discharge pipeline.

[0039] like Figure 6 As shown, a schematic diagram of signals output by strain resistors 6-1-5 or four-quadrant photoelectric sensors 6-2-6 detected by multiple groups of upper pipeline fluid sensors 6-1 and lower pipeline fluid sensors 6-2 at different times is given, and the discharge pipeline 1 includes a chromium treated water discharge pipeline, a zinc treated water discharge pipeline, a copper treated water discharge pipeline, a lead treated water discharge pipeline, and a nickel treated water discharge pipeline.

[0040] Figure 6 In the time period 0-t1, treated water flows through the chromium treated water discharge pipeline, the lead treated water discharge pipeline and the nickel treated water discharge pipeline; in the time period t1-t2, only treated water flows through the copper treated water discharge pipeline; in the time period t2 to t3, only treated water flows through the chromium treated water discharge pipeline, the zinc treated water discharge pipeline and the copper treated water discharge pipeline; in the time period t3 to t4, no treated water flows; in the time period t4 to t5, no treated water flows through the zinc treated water discharge pipeline.

[0041] Digital flow measurement units 9 are installed in the original electroplating wastewater pipelines. Figure 7In the figure, the digital flow measurement unit 9-1, the digital flow measurement unit 9-2, the digital flow measurement unit 9-3, the digital flow measurement unit 9-4, and the digital flow measurement unit 9-5 separated by the space dividing line 12 are respectively installed in the chromium treatment water discharge pipeline of the discharge pipeline 1-1, the zinc treatment water discharge pipeline of 1-2, the copper treatment water discharge pipeline of 1-3, the lead treatment water discharge pipeline of 1-4, and the nickel treatment water discharge pipeline of 1-5. The fluid flow sensor unit 6 is installed in the electroplating centralized control area pipeline treatment wastewater discharge concentration area 13. The fluid flow sensor unit 6 is divided into two types, the first type is the upper pipeline fluid sensor 6-1, and the second type is the lower pipeline fluid sensor 6-2. The fluid flow sensing unit 6 and the digital flow measurement unit 9 are connected to the background computer or other terminal 11 through a public network communication unit 10. The upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2 are used to obtain the collected data information, and the digital flow measurement unit 9 is used to obtain the flow information of the flow meter installed on the corresponding discharge pipeline 1; the information of the upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2 is used to establish corresponding database information with the corresponding flow meter information, so as to obtain the real corresponding flow information through the information of the upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2.

[0042] The information of the upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2 is used to establish corresponding database information with the corresponding flow meter information. The information of the upper pipeline fluid sensor 6-1 and the lower pipeline fluid sensor 6-2 is obtained by Fourier transform to obtain the amplitude-frequency signal of the vibration quantity, and then the corresponding relationship is established with the flow data corresponding to the digital flow measurement unit.

[0043] By rationally arranging and designing the discharge pipeline structure, the production monitoring of the discharge pipe can be realized without damaging the existing pipeline, so that the production status and the discharge volume of chromium, zinc, copper, lead and nickel treated water at different times can be known at any time. This has brought convenience to the supervision and management departments in controlling the electroplating enterprises.

[0044] In the present invention, the wastewater treated in the electroplating centralized control area pipeline wastewater discharge concentrated area 13 is finally discharged after passing through the mixing area 14 and meeting the standards.

[0045] Therefore, the working status of the chromium treated water discharge pipeline, zinc treated water discharge pipeline, copper treated water discharge pipeline, lead treated water discharge pipeline and nickel treated water discharge pipeline can be discovered on the background computer or other terminals, such as whether treated water flows through and how much the flow rate is, so that the regulator can understand the status of the treated water.

[0046] The present invention does not require the installation of a flow meter in the pipeline, and the construction is convenient.

[0047] The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry and are not described one by one here.
