Description

Technical Field

[0001] The invention relates to the technical field of wastewater discharge monitoring, and in particular to a wastewater discharge monitoring instrument. Background Art

[0002] With the rapid economic development, many enterprises will produce industrial wastewater in the process of industrial production, and the industrial wastewater will be discharged through sewage pipes. In order to avoid the industrial wastewater from causing greater pollution and damage to the environment, it is usually necessary to install a wastewater flow meter on the sewage pipe to monitor and control the wastewater discharge in real time, so as to achieve the purpose of energy saving, emission reduction and environmental protection.

[0003] Existing wastewater flow meters are usually connected between two sections of sewage pipes, and ensure that the wastewater can flow through the wastewater flow meter in full pipes, and then the wastewater flow meter monitors the flow of the flowing wastewater. However, when the amount of wastewater discharged in the sewage pipe is small, that is, when the water level of the wastewater in the sewage pipe is low (for example, the water level is below 20 cm), the existing wastewater flow meter cannot monitor the wastewater flow. Therefore, some companies take advantage of this loophole to secretly discharge industrial wastewater. The small amount of wastewater that cannot be monitored will also cause great damage to the environment after years of discharge.

[0004] The above contents are only used to assist in understanding the technical solution of the invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0005] The main purpose of the present invention is to provide a wastewater discharge monitoring instrument, which aims to solve the technical problem that the existing wastewater flow meter cannot monitor the discharge flow when the wastewater level in the sewage pipe is low.

[0011] In one embodiment, the wastewater discharge detector further includes a filter screen, and the filter screen is installed at one end of the mounting portion, and the other end is connected to the water retaining portion.

[0012] In one embodiment, the water retaining member further includes a limiting portion, and the limiting portion is connected to the outer peripheral wall of the mounting portion.

[0013] In one embodiment, the flow meter has a water inlet, and the water inlet is provided with a liquid level valve, and the liquid level valve is used to open or close the water inlet of the flow meter according to the wastewater level in the sewage pipe; and / or, the water outlet is provided with a valve cover, when wastewater is discharged, the valve cover is pushed open by the wastewater; when no wastewater is discharged, the valve cover closes the water outlet.

[0014] In one embodiment, the valve cover is rotatably installed at the water outlet through a pin shaft, and a magnet is also provided on the valve cover, and the magnet and the pin shaft are arranged opposite to each other in the radial direction of the water outlet; the wastewater discharge monitor also includes a sensing module, and the sensing module and the pin shaft are arranged opposite to each other in the radial direction of the water outlet and can sense the magnet.

[0016] The wastewater discharge monitoring instrument of the present invention blocks the wastewater with a lower overall water level in the sewage pipe by using a water retaining member, thereby preventing the wastewater from being secretly discharged or leaked from the sewage pipe. At the same time, the water retaining member is provided with an installation opening that passes through it, and the installation opening is smaller than or even much smaller than the sewage pipe. A flow meter matching its size is installed at the installation opening, and the flow meter can discharge the blocked wastewater and monitor the flow of the discharged wastewater at the same time.

[0033] The invention provides a wastewater discharge monitoring instrument.

[0034] In the embodiment of the present invention, Figures 1 to 4 As shown, the wastewater discharge monitoring instrument includes a water retaining member 20 and a flow meter 30. Figure 4 As shown, the water retaining member 20 is used to be installed at the drain outlet of the sewage pipe 80 to prevent the wastewater in the sewage pipe 80 from being discharged. The water retaining member 20 can be installed on the sewage pipe 80 by screwing, bonding, clamping, etc., and its specific structure can be a water retaining plate, a water retaining block, etc., and its material, shape, and size can be set according to the actual situation of the sewage pipe 80, the installation method, etc. For example, taking the sewage pipe 80 as a round pipe as an example, the water retaining member 20 can be a plate-like structure and directly encapsulated at the drain outlet of the sewage pipe 80, and when the water retaining member 20 is a plate-like structure, it can be a circular plate, a square plate, a semicircular plate, etc. Alternatively, the water retaining member 20 can also be a cylindrical structure, and the wastewater is blocked from being discharged by being plugged into the sewage pipe 80. Alternatively, the water retaining member 20 can also be a cylindrical structure with one end open, and then the wastewater is blocked from being discharged by being sleeved outside the drain outlet of the sewage pipe 80, and the specific structure can be set according to the actual situation. The material of the water retaining member 20 can be metal, plastic, alloy, etc., which is not specifically limited here.

[0035] It should be noted that when the water retaining member 20 is designed as a semicircular water retaining plate, the semicircular water retaining plate should be sufficient to block all wastewater in the sewage pipe 80 to prevent wastewater leakage.

[0036] Please combine Figures 3 to 5 , the water retaining member 20 is also provided with an installation port 21. The flow meter 30 is installed at the installation port 21, and is used to discharge the wastewater blocked by the water retaining member 20, and to monitor the flow of the discharged wastewater. The size of the installation port 21 is smaller than or even much smaller than the sewage pipe 80, so as to install a smaller flow meter 30. The shape, number, position, etc. of the installation port 21 are not specifically limited here. For example, the installation port 21 can be circular, and there are multiple installation ports, and a flow meter 30 is correspondingly installed on each installation port 21. As for the position of the installation port 21 on the water retaining member 20, in order to ensure that the blocked wastewater can be smoothly discharged by the flow meter 30 at the installation port 21, when the water retaining member 20 is installed on the sewage pipe 80, the installation port 21 can be relatively close to the inner circumferential wall of the drain pipe, and close to the low point of the entire inner circumferential wall, to avoid the accumulation of wastewater and the inability to discharge.

[0037] The size of the flow meter 30 is adapted to the size of the mounting port 21. For example, a smaller turbine flow meter or other micro flow meter can be used, thereby making it possible to discharge a small amount of wastewater even more minutely, ensuring that the wastewater can fully flow through the flow meter 30 (Note: The "tube" in "full tube flowing through the flow meter 30" refers to the measuring tube in the flow meter 30, the same below), thereby monitoring the flow of the discharged wastewater.

[0038] It can be understood that the wastewater discharge monitoring instrument of the present invention blocks the wastewater with a lower overall water level in the sewage pipe 80 by using a water retaining member 20, thereby preventing the wastewater from being secretly discharged or leaked from the sewage pipe 80. At the same time, the water retaining member 20 is provided with an installation port 21 that passes through it, and the installation port 21 is smaller than or even much smaller than the sewage pipe 80. A flow meter 30 matching its size is installed at the installation port 21, and the flow meter 30 can discharge the blocked wastewater and monitor the flow rate of the discharged wastewater at the same time. That is, the wastewater discharge monitoring instrument of the present invention can first block the wastewater to avoid secret discharge or leak, and at the same time, can further minimize the discharge of the already small amount of wastewater through the flow meter 30, and then monitor the flow rate of the discharged wastewater, which effectively solves the technical problem that the existing wastewater flow meter 30 cannot monitor the discharge flow rate when the wastewater water level in the sewage pipe 80 is low.

[0039] In one embodiment, if Figure 5 As shown, the water retaining member 20 includes a mounting portion 22 and a water retaining portion 23. The mounting portion 22 is a hollow cylindrical structure and is used to be mutually socketed with the sewage pipe 80. The water retaining portion 23 is connected to the inner circumferential wall of the mounting portion 22 and is used to block waste water. The mounting port 21 is provided on the water retaining portion 23.

[0040] Among them, the sleeve connection mode of the mounting part 22 and the sewage pipe 80 can be that the mounting part 22 is sleeved outside the sewage pipe 80, and at least one end of the mounting part 22 is open so as to be sleeved outside the sewage pipe 80. Alternatively, the mounting part 22 is inserted into the sewage pipe 80, that is, the sewage pipe 80 is sleeved outside the mounting part 22, and the specific selection can be made according to the actual situation. In order to prevent the wastewater from leaking and being discharged from the gap between the mounting part 22 and the sewage pipe 80, a sealing gasket, a sealant, etc. can be set between the sleeve surfaces of the mounting part 22 and the sewage pipe 80 during the sleeve connection.

[0041] The water retaining portion 23 and the mounting portion 22 can be connected together by gluing, screwing, clamping, etc., and attention should be paid to the sealing of the connection gap during connection to prevent wastewater from leaking out. Of course, the water retaining portion 23 and the mounting portion 22 can also be arranged in one piece, so that the sealing is better and wastewater can be prevented from leaking out.

[0042] In one embodiment, if Figure 5 As shown, the installation opening 21 is arranged close to the inner peripheral wall of the installation portion 22. It can be understood that such an arrangement enables the installation opening 21 to be close to the inner wall of the sewage pipe 80 when the installation portion 22 is sleeved on the sewage pipe 80. In addition, during the sleeve connection between the installation portion 22 and the sewage pipe 80, the position of the installation opening 21 can be rotated to adjust the installation opening 21 so that the installation opening 21 is as close as possible to the low point of the inner peripheral wall of the sewage pipe 80 (here, it refers to the low point position in the drainage pipe where water is more likely to accumulate), thereby avoiding the situation where some wastewater accumulates and cannot be discharged.

[0043] In one embodiment, if Figure 5 As shown, the installation port 21 is provided with a plurality of flowmeters 30. It can be understood that the provision of a plurality of installation ports 21 and a plurality of flowmeters 30 can improve the discharge efficiency of wastewater, and when calculating the total discharge flow, the data of each flowmeter 30 can be added.

[0044] In one embodiment, if Figure 6 As shown, the arrangement of the plurality of mounting ports 21 may be in various forms, for example, the plurality of mounting ports 21 may be arranged in a matrix, which facilitates the processing and positioning of the mounting ports 21 and the installation of the flow meter 30 .

[0045] Or, if Figure 7As shown, the multiple installation openings 21 are arranged at intervals along the circumferential direction of the installation portion 22, for example, the multiple installation openings 21 are arranged in a circle, so that no matter how the water retaining member 20 is installed, there will be an installation opening 21 close to or corresponding to the low point of the inner circumferential wall of the sewage pipe 80. Or it is more convenient for the assembler to correspond the installation opening 21 to the low point of the inner circumferential wall of the sewage pipe 80, so as to avoid the accumulation of wastewater at the lowest point of the inner circumferential wall of the sewage pipe 80. Of course, the multiple installation openings 21 can also be arranged in a multi-circle structure.

[0046] Or, if Figure 8 As shown, the plurality of installation openings 21 are arranged at intervals along the radial direction of the installation portion 22. For example, taking the horizontal extension of the sewage pipe 80 as an example, when the installation portion 22 is installed and sleeved on the sewage pipe 80, the plurality of installation openings 21 are arranged vertically from top to bottom. It can be understood that when the blocked wastewater level gradually rises, the flow meters 30 from bottom to top also join the drainage and monitoring team one by one, thereby improving the wastewater discharge efficiency and monitoring efficiency.

[0047] Or, if Fig. 9 As shown, the multiple mounting openings 21 are arranged in a fan shape, and the center point of the fan shape is on the central axis of the mounting portion 22. Specifically, the multiple mounting openings 21 are arranged in a matrix, arranged along the circumferential direction of the mounting portion 22, and arranged along the radial direction of the mounting portion 22, and finally form a fan-shaped arrangement structure together. In this way, the advantages brought by the above-mentioned various arrangement methods can be combined to improve the overall performance of the wastewater discharge monitoring instrument.

[0048] In one embodiment, if Figure 3 As shown, the wastewater discharge detector 10 also includes a filter screen 40, one end of the mounting portion 22 is equipped with the filter screen 40, and the other end is connected to the water retaining portion 23. The filter screen 40 can filter out larger impurities in the wastewater, prevent the impurities from flowing into the flow meter 30 and affecting the monitoring of the flow meter 30, and ensure the accuracy of the monitoring data. In this embodiment, the mounting portion 22 is plugged into the sewage pipe 80, so that the filter screen 40 can be conveniently installed at the end of the mounting portion 22. The filter screen 40 is detachably mounted on the mounting portion 22, and the filter screen 40 can be removed for cleaning or replacement.

[0049] In one embodiment, if Figure 5 As shown, the mounting portion 22 of the water retaining member 20 is used to be inserted into the sewage pipe 80, and the water retaining member 20 also includes a limiting portion 24, and the limiting portion 24 is connected to the outer peripheral wall of the mounting portion 22. It can be understood that when the water retaining member 20 is installed on the sewage pipe 80, the limiting portion 24 can limit the length of the mounting portion 22 and the sewage pipe 80 being connected to each other, so that the assembler does not need to measure and position, thereby improving the assembly efficiency.

[0050] Of course, as an equivalent replacement solution, when the mounting portion 22 of the water retaining member 20 is used to be mounted outside the sewage pipe 80 , the limiting portion 24 can also be connected to the inner circumferential wall of the mounting portion 22 .

[0051] Because the monitoring data of the flow meter 30 is the most accurate when the wastewater flows through the pipe fully, in order to ensure that each flow meter 30 can ensure that "the wastewater flows through the pipe fully" when discharging wastewater, in one embodiment, Fig.10 As shown, the flow meter 30 has a water inlet 31 and a water outlet 32. The water inlet 31 is provided with a liquid level valve 33, and the liquid level valve 33 is used to open or close the water inlet 31 of the flow meter 30 according to the wastewater level in the sewage pipe 80. Specifically, when the liquid level valve 33 senses that the wastewater level has completely submerged the water inlet 31 of the corresponding flow meter 30, the water inlet 31 is opened and the wastewater is discharged, and flow monitoring is performed at the same time. When the liquid level valve 33 senses that the wastewater level has not completely submerged the water inlet 31 of the corresponding flow meter 30, the water inlet 31 is closed to prevent the wastewater from being discharged, so that the wastewater can be discharged from other completely submerged flow meters 30. In this way, each flow meter 30 can ensure that the wastewater flows through the full pipe when discharging wastewater, thereby making the monitoring data more accurate.

[0052] In one embodiment, if Fig.10 As shown, the water outlet 32 ​​is provided with a valve cover 34. When wastewater is discharged, the valve cover 34 is pushed open by the wastewater; when no wastewater is discharged, the valve cover 34 closes the water outlet 32. The valve cover 34 can be used to record the time when each flow meter 30 discharges wastewater each time, that is, the drainage time is calculated by the interval between the opening and closing of the valve cover 34.

[0053] In addition, the valve cover 34 can also be used to check each other with the flow meter 30. Specifically, if the valve cover 34 is open but the flow meter 30 does not detect the amount of water discharged, it means that the flow meter 30 may be damaged and needs to be checked and repaired in time. If the flow meter 30 rotates but the valve cover 34 is not opened, it means that only some wastewater has pushed through the flow meter 30 and is monitored by the flow meter 30 (for example, the blades in the turbine flow meter 30 are pushed by some wastewater), but the wastewater does not actually push open the valve cover 34 and be discharged. In this case, when calculating the sum of the water discharge of each flow meter 30, the data of this flow meter 30 can be excluded to ensure the accuracy of the monitoring data.

[0054] In one embodiment, if Fig.10As shown, the valve cover 34 is rotatably installed at the water outlet 32 ​​through a pin shaft 341, and a magnet 342 is also provided on the valve cover 34, and the magnet 342 and the pin shaft 341 are arranged relative to each other in the radial direction of the water outlet 32; the wastewater discharge monitor also includes a sensing module 50, and the sensing module 50 and the pin shaft 341 are arranged relative to each other in the radial direction of the water outlet 32, and can sense the magnet 342.

[0055] In this embodiment, when wastewater pushes the valve cover 34 open and is discharged, the induction between the magnet 342 on the valve cover 34 and the sensing module 50 is disconnected, and the discharge time begins to be calculated. When wastewater is no longer discharged and the valve cover 34 is turned back to its original position, the sensing module 50 senses the magnet 342 again and stops timing, and then calculates the discharge time through the interval between the opening and closing of the valve cover. In addition, the pin 341 and the magnet 342 make the valve cover 34 simple in structure and easy to obtain and assemble.

[0056] In one embodiment, if Figure 1 As shown, the wastewater discharge monitor also includes a communication module 60, and the flow meter 30, the liquid level valve 33 and the sensing module 50 are all electrically connected to the communication module 60. It can be understood that the communication module 60 can send the monitoring data to the remote control terminal, and then remotely observe the monitoring data. In this embodiment, the communication module 60 is connected to the water retaining member 20 through the mounting rod 70, and is connected to the flow meter 30 through a cable.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
