Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment 1 of the present invention, which provides a liquid concentration monitoring and alarming device 11, including a detection component connected in series to a liquid pipeline 10, where the detection component includes a water tank 2, a specific gravity meter 5, a position sensor and a first control unit. The tank 2 is used to provide a liquid location for the hydrometer 5, the hydrometer 5 is made according to the Archimedes' law and the equilibrium condition of the object floating on the liquid surface. The glass tube is a closed glass tube, one end of the glass tube is uniform in thickness, the inner wall of the glass tube is pasted with scale paper, the scale is uneven, the glass tube is sparse at the upper part and dense at the lower part, the other end of the glass tube is slightly expanded to be in a bubble shape, and small lead particles or mercury are filled in the bubble, so that the glass tube can be vertically immersed to a sufficient depth in a detected liquid and can stably float in the liquid, namely, the glass tube can automatically recover to a vertical static position when the glass tube is shaken. When the hydrometer 5 floats in the liquid, its own weight is equal to the weight of the liquid it displaces. Thus, the hydrometer 5 is calibrated by utilizing the relation that the liquid is immersed into different depths and the pressure is different. The density change of the liquid can be reflected in real time by measuring the height position change of the liquid in the water tank 2 by the specific gravity meter 5. The position sensor is used for measuring the height position of the hydrometer 5, and the first control unit is used for analyzing and processing the measurement data.
In this embodiment, the water tank 2 is provided with a liquid inlet 8 and a liquid outlet 1, and the water tank 2 is connected in series to the liquid pipeline 10 through the liquid inlet 8 and the liquid outlet 1. The water tank 2 is connected in series on the liquid pipeline 10, liquid continuously enters the water tank 2 from the liquid inlet 8 and continuously flows out from the liquid outlet 1, the liquid in the water tank 2 is continuously kept to be renewed, and the concentration of the liquid in the water tank 2 can be reflected to the concentration of the liquid in the liquid pipeline 10 in real time.
In the present embodiment, the specific gravity gauge 5 is provided in the water tank 2, the position sensor faces the specific gravity gauge 5 and detects a height position of the specific gravity gauge 5 in the water tank 2, the position sensor is connected to the first control unit, and the first control unit is connected to an alarm unit. When the concentration of the liquid in the water tank 2 changes, the height position of the specific gravity meter 5 changes. The position sensor monitors the change of the height position of the hydrometer 5 in real time and transmits the monitored position height data to the first control unit, and the first control unit processes the position height data by analysis and sets a maximum concentration rated value (the maximum concentration of the liquid which can be used for production or processing) and a minimum concentration rated value (the minimum concentration of the liquid which can be used for production or processing). When the concentration exceeds or is lower than the two concentration rated values after analysis and processing, the first control unit controls the alarm assembly to give an alarm.
It should be noted that, in this embodiment, the liquid flow rate of the liquid inlet 8 is the same as that of the liquid outlet 1, so that the liquid volume in the water tank 2 can be kept in dynamic balance, and the influence factor on the position height of the gravimetric meter 5 can be ignored.
Therefore, the liquid concentration monitoring and alarming device 11 can realize the real-time monitoring of the liquid concentration and ensure that the monitoring is not intermittent, thereby ensuring that the liquid concentration is in a controllable alarming state in real time.

The limiting block 4 is vertically provided with a sliding groove, and the upper part of the hydrometer 5 is arranged in the sliding groove and can freely slide along the sliding groove.
In this embodiment, the stopper 4 is used to limit the moving direction of the hydrometer 5, specifically, to limit the hydrometer 5 to move only in the vertical direction. The sliding groove has a guiding function, so that the hydrometer 5 can slide only in the direction of the opening of the sliding groove under the action of liquid buoyancy. In this embodiment, the length of the slide groove is longer than the stroke of the specific gravity gauge 5. Therefore, the change of the height position of the specific gravity meter 5 caused by the change of the liquid density only occurs in the change of the height position of the specific gravity meter 5 in the vertical direction, and the measurement is more accurate.

The infrared transmitting module 7 and the infrared receiving module 3 are respectively positioned at two sides of the through hole 6, and an infrared beam signal sent by the infrared transmitting module 7 passes through the through hole 6 to be received by the infrared receiving module 3. When the concentration of the liquid reaches the set maximum concentration rated value, the lowest point of the through hole 6 and the infrared beam signal are at critical positions, if the concentration of the liquid rises again, the infrared beam signal is shielded, the infrared receiving module 3 cannot receive the infrared beam signal, the infrared receiving module 3 generates an interrupt signal and sends the signal to the first control unit, and after the first control unit receives the signal, the first control unit judges the over-concentration critical value through analysis and judgment and controls the alarm assembly to send out an alarm. Similarly, when the concentration of the liquid reaches the set minimum high concentration rated value, the highest point of the through hole 6 and the infrared beam signal are in the critical position, and at the moment, the first control unit controls the alarm assembly to give an alarm.
In some embodiments of the present invention, the position sensor includes a displacement sensor (not shown) facing the specific gravity gauge 5 for detecting a linear displacement of the specific gravity gauge 5, and the displacement sensor is connected to the first control unit.
In this embodiment, the sensor may be a displacement sensor for directly detecting a change in the height position of the specific gravity meter 5 and transmitting a detected height position signal of the specific gravity meter 5 to the first control unit in real time. After receiving the signal, the first control unit judges whether the signal is in the height range of the highest concentration rated value and the lowest concentration rated value through logic analysis, and if the signal is out of the range, the first control unit controls the alarm assembly to give an alarm.
Referring to fig. 1, in some embodiments of the present invention, a placing cylinder 9 is disposed in the water tank 2, and a lower portion of the specific gravity gauge 5 is disposed in the placing cylinder 9.
In this embodiment, the hydrometer 5 is moved in the other direction in order to ensure that it is not influenced by the flow, since the liquid in the tank 2 is in the flow turn. The placing cylinder 9 is used for placing the hydrometer 5, which can ensure that the lower part of the hydrometer 5 does not deviate and only moves in one vertical direction, thereby ensuring the accuracy of the concentration of the liquid reacted by the hydrometer 5.
Referring to fig. 4, in some embodiments of the present invention, the alarm assembly includes an audible alarm and a light alarm, and the audible alarm and the light alarm are respectively connected to the first control unit.
In this embodiment, the sound alarm and the light alarm can respectively send out sound alarm signals and light alarm signals to send out alarm information to workers.
Referring to fig. 4, in some embodiments of the present invention, the first control unit is connected to an upper computer, and the upper computer is connected to a display module and a command input end.
In this embodiment, the host computer is used for connecting a first control unit to realize remote monitoring. The first control unit sends the processed monitoring signals to the upper computer in real time, and the upper computer controls the display module to display monitoring results. Meanwhile, the command input end can control the first control unit, and the highest rated value, the lowest rated value and the like are written into the first control unit through the upper computer, so that concentration monitoring of liquids with different properties is realized.
In some embodiments of this embodiment, the height of the liquid inlet 8 is greater than the height of the liquid outlet 1.
In use, the position sensor monitors the change in the height position of the hydrometer 5 in real time and transmits the monitored position height data to the first control unit, and the first control unit processes the position height data by analysis and sets a maximum concentration rating (maximum concentration at which the liquid can be used for production or processing) and a minimum concentration rating (minimum concentration at which the liquid can be used for production or processing). When the concentration exceeds or is lower than the two concentration rated values after analysis and processing, the first control unit controls the alarm assembly to give an alarm.
