[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 the sewage pipe. 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] The industrial wastewater discharge flow monitoring device is a device used to monitor and control the discharge flow of industrial wastewater. Electromagnetic flow meters are usually used for monitoring. They are usually installed on wastewater discharge pipes. They use sensors and data processing systems to monitor the flow of wastewater in real time and control it according to preset discharge standards to ensure that wastewater discharge meets environmental protection requirements.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 - Figure 6 As shown, an industrial wastewater discharge flow monitoring device includes a sewage inlet pipe 1, which is used to connect to a pipe for discharging industrial wastewater. A uniform mechanism 2 is provided at the bottom of the sewage inlet pipe 1, which is used to crush impurities in the industrial wastewater. Large and agglomerated impurities can be crushed to make the impurities in the industrial wastewater in a uniform state, so that the flow rate of the industrial wastewater is more stable and uniform when it is discharged, so that the flow rate can be measured more accurately. Figure 2 As shown, the equalizing mechanism 2 includes an arc-shaped tube 21, the outer center position of the arc-shaped tube 21 is fixedly connected to the sewage inlet pipe 1, and the inner diameter of the arc-shaped tube 21 is larger than the inner diameter of the sewage inlet pipe 1, so that industrial wastewater will not be blocked when entering the arc-shaped tube 21. An even number of equalizing tubes 22 are installed on the inner side of the arc-shaped tube 21, and the even number of equalizing tubes 22 are symmetrically distributed relative to the sewage inlet pipe 1, and the equalizing tubes 22 on each side are distributed in an array, so that industrial wastewater can enter the equalizing tube 22 evenly, and the pressure and flow rate are basically the same.

[0027] like Figure 2- Figure 3 As shown, a rotating rod 24 is provided in the flow equalizing tube 22, and one end of the rotating rod 24 is rotatably connected to the arc tube 21. A rotating blade 25 is fixedly installed on the surface of the rotating rod 24 located at one end of the flow equalizing tube 22 close to the arc tube 21. The blades of the rotating blade 25 are a smooth arc structure, and the entire rotating blade 25 is a truncated cone structure with a larger upper part and a smaller lower part, so that when the industrial wastewater flows through, the flow velocity and flow direction will change, so that when the industrial wastewater impacts the rotating blade 25, it can drive the rotating blade 25 to rotate. When the rotating blade 25 rotates, it will drive the industrial wastewater to generate turbulence or vortex, so that the bubbles in the industrial wastewater are torn apart by the shear force generated by the rotation.

[0028] A plurality of ball mills 26 are fixedly installed on the rotating rod 24 inside the flow equalizing tube 22. The diameters of the plurality of ball mills 26 are different, and the spacing between the ball mills 26 and the inner wall of the flow equalizing tube 22 is also different. The spacing between the ball mills 26 and the inner wall of the flow equalizing tube 22 becomes smaller and smaller along the flow direction of the industrial wastewater, and is used to crush impurities and agglomerated particles in the industrial wastewater. The difficulty of crushing and the uniformity after crushing can be effectively reduced by performing graded crushing with the plurality of ball mills 26. When the industrial wastewater passes through the gap between the ball mills 26 and the flow equalizing tube 22, the bubbles can be effectively crushed.

[0029] At the same time, the flow-equalizing tube 22 is a truncated cone structure, so that the water pressure during the flow increases, the impact force on impurities also increases, and it is easier to crush the impurities. The other end of the flow-equalizing tube 22 is fixedly connected to a spherical bin 23, and the industrial wastewater after being evenly distributed will impact on the surface of the spherical bin 23 or the water surface in the spherical bin 23. The impact force of the industrial wastewater is absorbed by the buffering of the inner wall of the spherical bin 23 and the water surface, so as to avoid the industrial wastewater from forming vortices, which may cause errors in the flow rate monitoring.

[0030] When there are many impurities in the industrial wastewater and a single flow equalizing tube 22 is blocked, the other flow equalizing tubes 22 can still work normally. Due to the blockage, the water pressure increases, and the flow rate of industrial wastewater in other flow equalizing tubes 22 is faster. When an even number of flow equalizing tubes 22 are blocked, the flow rate of industrial wastewater entering the arc tube 21 remains unchanged, so that the water pressure in the arc tube 21 is continuously increased, which can drive the rotating blades 25 to work and crush the impurities.

[0031] The spherical bin 23 is provided with an exhaust pipe and an exhaust valve for exhausting the gas of the shredded bubbles. The two ends of the arc tube 21 are also fixedly connected with connecting valves 27, which can be connected to a suction device to extract the industrial waste water retained in the uniform mechanism 2, or connected to clean water, so that clean water can be introduced through the connecting valve 27 to impact the entire device, achieving a cleaning effect.

[0032] like Figure 4 - Figure 6As shown, the spherical bin 23 is also connected with a flow stabilizing mechanism 3, which is used to buffer and stabilize the industrial wastewater passing through the uniform mechanism 2, and adjust the turbulent water flow, so that the flow velocity and flow rate of the discharged industrial wastewater are stable, which is convenient for improving the accuracy of monitoring. The flow stabilizing mechanism 3 includes a flow stabilizing tube 31, which is fixedly connected to the spherical bin 23, so that the industrial wastewater that has been broken and uniformed by the uniform mechanism 2 enters the flow stabilizing tube 31 and is temporarily stored, and the chaotic water flow is smoothed. The bottom end of the flow stabilizing tube 31 is fixedly connected with a base 32, and the base 32 includes a mounting frame 321, which is fixedly connected to the flow stabilizing tube 31, and a circular hole 322 is opened at the center of the mounting frame 321 for discharging industrial wastewater. A sealing assembly 35 is arranged in the circular hole 322, which is used to seal and open and close the circular hole 322, so as to control whether the industrial wastewater passes through the circular hole 322. The sealing assembly 35 includes a sealing plate 352, which is slidably connected to the circular hole 322. A top plate 351 is fixedly installed on the top of the sealing plate 352. The diameter of the top plate 351 is larger than the circular hole 322, so that the top plate 351 cannot pass through the circular hole 322. A plurality of connecting rods 353 are fixedly connected to the bottom end of the sealing plate 352. A limiting ring 354 is fixedly installed on the bottom end of the connecting rod 353. The outer diameter of the limiting ring 354 is larger than the diameter of the circular hole 322, so that the sealing plate 352 can only move up and down along the central axis of the circular hole 322 and will not separate from the circular hole 322, so that the sealing plate 352 is more stable for sealing and opening the circular hole 322. The top plate 351 is connected to a float 38 through a connecting rope 37, a magnet 39 is fixedly mounted on the float 38, a plurality of limit rods 36 are fixedly mounted on the mounting frame 321, and an adsorption plate 310 is fixedly mounted on the top of the limit rod 36. The float 38 can be driven to rise by the rise of the water level. The plurality of limit rods 36 are arranged in a circular row, and are used to limit the movement trajectory of the float 38 to prevent the float 38 from shaking due to the impact of the water flow, so that the contact area between the magnet 39 and the adsorption plate 310 is consistent each time, and the repeatable performance is more stable. At the same time, it can prevent the magnet 39 and the adsorption plate 310 from being separated due to the impact of the water flow, and fluctuating on the water surface, causing the sealing plate 352 to shake up and down, so that the stability of the industrial wastewater when passing through the circular hole 322 becomes poor, and finally the industrial wastewater flow rate is uneven, affecting the monitoring accuracy of the flow rate.

[0033] When the water level rises to a certain height, the magnet 39 is connected to the adsorption plate 310, and the float 38 drives the sealing plate 352 to detach from the circular hole 322 through the connecting rope 37, so that the industrial wastewater can pass through the circular hole 322. Since the water level is higher than the top of the flow-stabilizing tube 31 at this time, the flow-stabilizing tube 31 is filled with industrial wastewater, and the industrial wastewater can pass through the circular hole 322 in the full tube. A connecting pipe 33 is fixedly installed at the bottom end of the flow-stabilizing tube 31. The connecting pipe 33 is a truncated cone structure, and the minimum diameter of the connecting pipe 33 is smaller than the diameter of the circular hole 322, so that the industrial wastewater entering the connecting pipe 33 through the circular hole 322 is in a full tube flow state when leaving, and the connecting pipe 33 provides a certain error compensation.

[0034] A connecting flange 34 is fixedly installed at the bottom end of the connecting pipe 33, and the connecting flange 34 and the electromagnetic flowmeter 4 are fixedly connected by bolts. An excitation coil is arranged inside the electromagnetic flowmeter 4, and electrodes are arranged on the inner surface. When current passes through these excitation coils, a magnetic field perpendicular to the flow direction of the fluid will be generated in the measuring tube of the flowmeter. When industrial wastewater flows through this magnetic field, it will cut the magnetic lines of force in the liquid, thereby generating an induced electromotive force on the electrodes on both sides of the coil. The measured induced electromotive force is converted into an electrical signal, which can be converted into a flow value and displayed after amplification and processing by a converter. The other end of the electromagnetic flowmeter 4 is connected to a sewage pipe 5 for discharging industrial wastewater.

[0035] It should be noted that the present invention is an industrial wastewater discharge flow monitoring device. When in use, the sewage inlet pipe 1 is connected to the industrial wastewater discharge pipe, and the industrial wastewater enters the arc tube 21 through the sewage inlet pipe 1. The impact of the water flow drives the rotating blades 25 to rotate, and the rotating blades 25 drive the ball mill 26 to rotate through the rotating rod 24, so that impurities and bubbles in the industrial wastewater can be broken. The evenly broken industrial wastewater is discharged into the spherical bin 23.

[0036] Although the impurities and bubbles in the industrial wastewater after the uniform mechanism 2 are broken, the flow direction of the industrial wastewater is disordered and the flow rate is uneven. After the industrial wastewater enters the spherical bin 23, it flows into the flow-stabilizing tube 31. The water flow will impact the surface of the spherical bin 23 or the water body, thereby buffering the impact of the water flow, and the water flow will only impact the spherical bin 23, and will not impact the water in the flow-stabilizing tube 31. When the water level in the spherical bin 23 and the flow-stabilizing tube 31 continues to rise, it will drive the float 38 to rise. When the float 38 rises to a certain height, the magnet 39 is adsorbed on the adsorption plate 310. At this time, the float 38 drives the sealing plate 352 to rise through the connecting rope 37, and the circular hole 322 is connected to the connecting pipe 33. The industrial wastewater can enter the inside of the connecting pipe 33 with a full pipe, and finally enter the inside of the electromagnetic flowmeter 4 with a full pipe, and be discharged through the sewage pipe 5. Since the industrial wastewater entering the electromagnetic flowmeter 4 is in a full and uniform state, and the bubbles are broken and discharged, the electromagnetic flowmeter 4 can monitor the discharge of industrial wastewater more accurately.

[0037] The above embodiments of the present invention can achieve the following beneficial effects:

[0038] 1. The present invention provides a uniform mechanism and a flow stabilizing mechanism, so that the industrial wastewater in the uniform mechanism uses the pressure and impact force of the water flow as a power source to drive the rotating blades and the ball mill to rotate, thereby evenly crushing the impurities and agglomerated particles in the industrial wastewater, and at the same time crushing the bubbles in the industrial wastewater, so that the flow rate of the industrial wastewater will not be affected by impurities and the flow rate is more uniform. The flow stabilizing mechanism ensures that the industrial wastewater passing through the electromagnetic flowmeter is full and flows evenly without turbulent industrial wastewater, thereby effectively improving the accuracy of the electromagnetic flowmeter in monitoring industrial wastewater discharge.

[0039] 2. The present invention sets a uniform mechanism, which can drive the rotating blades to rotate under the impact of industrial wastewater, and the rotating blades drive the rotating rods to rotate, and the rotation of the rotating rods drives the ball mill to rotate to crush the impurities and agglomerates in the industrial wastewater, so that the impurities in the industrial wastewater are in a uniform state, and will not affect the flow rate of the industrial wastewater, so that the flow rate is uniform and stable, which effectively improves the measurement accuracy of the electromagnetic flowmeter and avoids multiple discharges of industrial wastewater. At the same time, due to the rotation of the rotating blades and the crushing of the ball mill, the bubbles in the industrial wastewater can be torn and crushed, which effectively reduces the bubble content in the industrial wastewater, thereby effectively improving the monitoring accuracy.

[0040] 3. The present invention provides a flow stabilizing mechanism so that the industrial wastewater passing through the uniform mechanism can be temporarily stored in the spherical bin and the flow stabilizing tube. Only when the water level exceeds a certain height can the sealing plate be driven by the float to separate from the circular hole, so that all the industrial wastewater entering the electromagnetic flowmeter flows through the full tube with a uniform and stable flow rate, thereby accurately monitoring the discharge of industrial wastewater.
