The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Fig. 1 is a schematic configuration diagram of a solution concentration control apparatus 100 involved in the present invention; fig. 2 is an exploded view of the solution concentration control apparatus 100 involved in the present invention.
The solution concentration control apparatus 100 according to the preferred embodiment of the present invention is used to control the concentration of a component in a target solution. The target solution may be contained in the target container 2. In some examples, the solution concentration control apparatus 100 may be used to detect the concentration of a dye solvent in a dyeing solution of the textile industry, i.e., the target solution may be the dyeing solution. During the dyeing process, the target container 2 is filled with a dyeing solution, the target container 2 is generally open, and the fabric is dyed in the target container 2. The dyeing solution generally comprises water and a dye solvent, wherein the concentration of the dye solvent in the dyeing solution has a high influence on the dyeing quality of the fabrics, and the concentration of the dye solvent is gradually reduced and the total amount of the dyeing solution is gradually reduced during the dyeing process. It is necessary to add the dye solvent to the dyeing solution in the target container 2 in time to maintain an appropriate concentration, and it is necessary to supplement water in time to maintain the total amount of the dyeing solution within an appropriate range.
As shown in FIGS. 1 and 2, the solution concentration control apparatus 100 may include a support 10, a concentration detecting assembly 20, a first feeding assembly 30, a pH detecting assembly 40, a second feeding assembly 50, a water level control assembly 60, a control module 70, and a pipe assembly 80. The concentration detecting assembly 20, the first feeding assembly 30, the pH detecting assembly 40, the second feeding assembly 50, the water level controlling assembly 60 and the control module 70 are all installed on the support 10.
In this embodiment, the main body of the stand 10 may be constructed of a profile or welded with steel pipes to provide support for other components. The bracket 10 may also include a plate or mounting member for mounting other components. In addition, the stand 10 may further include a sheet metal door provided at the periphery of the main body and casters or a foot cup provided at the bottom of the main body.
In the present embodiment, the concentration detection assembly 20 is used to detect the concentration of the first solvent in the target solution. The target solution may be a dyeing solution and the first solvent may be a dye solvent. Methods for detecting the concentration of a solution include a tuning fork concentration meter, a refractometer, and the like. The tuning fork concentration meter detects the liquid concentration by utilizing the corresponding relation between the liquid concentration and the sound frequency, and the detection precision of the tuning fork concentration meter is greatly influenced by environmental noise and liquid impurities. The refractometer detects the liquid concentration by utilizing the corresponding relation between substances and the optical refractive index, and the detection precision of the refractometer is greatly influenced by liquid impurities. In the present embodiment, it is preferable to detect the concentration of the solution by measuring and calculating the density of the solution to reduce the influence of environmental noise and liquid impurities on the detection accuracy. The concentration detection module 20 includes: the device comprises a first container 21, a floating member 22, a pressure sensor 23, a force transmission member 24, a first temperature sensor 25, a temperature control assembly 26, a water pump 27 and a data processing module. The data processing module may be included in the control module 70. An input port of the water pump 27 is communicated with the target container 2, an output port of the water pump 27 is communicated with the first container 21, and the water pump 27 is used for conveying the target solution in the target container 2 to the first container 21. During the dyeing process, the fabric may need to be moved in the target container 2, and it is not suitable to arrange too many parts in the target container 2, so that it is necessary to draw part of the target solution from the target container 2 for inspection. The water pump 27 may be mounted on the frame 10.
Fig. 3 is a sectional view of the first container 21 relating to the present invention.
In the present embodiment, as shown in fig. 3, the first container 21 may have a barrel shape with one end open. The first container 21 includes a containing chamber 211 for containing the target solution and an opening communicating with the containing chamber 211. The sidewall of the first container 21 is provided with a first interface 212 and a second interface 215 which are communicated with the accommodating cavity 211, the first interface 212 is located on one side of the second interface 215 far away from the bottom of the accommodating cavity 211, that is, the first interface 212 is higher than the second interface 215 with reference to the bottom of the accommodating cavity 211. The first and second ports 212 and 215 are used to control the water level of the first container 21. The solution concentration detecting apparatus 100 further includes a water level pipe 216 and an overflow pipe 81, wherein both ends of the water level pipe 216 are respectively connected to the first connector 212 and the second connector 215, and one end of the overflow pipe 81 is communicated with the water level pipe 216. An inlet pipe 218 may be further provided at a sidewall of the first container 21, and the inlet pipe 218 communicates with the accommodating chamber 211. An output port of the water pump 27 communicates with the water inlet pipe 218, and the target liquid can be injected into the accommodating chamber 211 through the water inlet pipe 218. With reference to the bottom of the receiving chamber 211, the inlet pipe 218 is higher than the overflow pipe 81. The material of the first container 21 may be metal or plastic. Preferably, the material of the first container 21 may be metal to improve corrosion resistance. The first container 21 may be mounted on the stand 10.
In the present embodiment, the floating member 22 is located in the accommodating cavity 211 for receiving the buoyancy of the target solution, and the volume of the floating member 22 immersed in the target solution is not changed. The floatation member 22 may have a closed space to reduce the overall density of the floatation member 22. The material of the float member 22 may be metal or plastic. The pressure sensor 23 is used to detect the difference between the gravity and the buoyancy experienced by the float member 22. The pressure sensor 23 is located on the side of the float element 22 remote from the bottom of the receiving space 211 and is connected to the float element 22 via a force transmission element 24. A pressure sensor 23 is located above the float 22 and may be mounted to the support 10. One end of the force transmission member 24 is connected to the floating member 22, and the other end is connected to the pressure sensor 23. The force-transmitting member 24 may be flexible or rigid.
In order to facilitate the force analysis of the floating member 22, the gravity of the floating member 22 is defined as G, the buoyancy of the floating member 22 subjected to the target solution is defined as F, the pulling force of the floating member 22 subjected to the pressure sensor 23 is defined as F1, the pushing force of the floating member 22 subjected to the pressure sensor 23 is defined as F2, the density of the target solution is defined as ρ, the gravitational acceleration is defined as G, and the volume of the floating member 22 immersed in the target solution is defined as v.
In some examples, the float member 22 is completely submerged in the target solution, and the density of the float member 22 is greater than the density of the target solution, the pressure sensor 23 is urged toward the float member 22 by the float member 22. As shown in fig. 2, the force-transmitting member 24 may be a rope. The pressure sensor 23 is subjected to the pulling force of the float 22. For force analysis of the float 22, there is the equation: f is ρ gv, G is ρ gv + F1, and ρ is (G-F1)/gv. G. g and v are known numbers, and if F1 is detected by the pressure sensor 23, the value of ρ can be obtained. Thereby, a change in the density of the target solution can be detected by the pressure sensor 23. And the density of the target solution is strongly correlated with the concentration, so that the change in the concentration of the target solution can be detected by the pressure sensor 23.
In the present embodiment, the first temperature sensor 25 is used to detect the temperature of the target solution. The concentration of the target solution generally changes with the temperature change, and temperature compensation is necessary in concentration detection to improve detection accuracy. The first temperature sensor 25 is installed at a sidewall of the first container 21 and is located at the bottom of the receiving cavity 211. If the target solution is injected from the inlet pipe 218 or the opening, enters the water level pipe 216 from the second port 215 and overflows from the overflow pipe 81, and the first temperature sensor 25 is disposed at the upper portion of the accommodating chamber 211, the temperature of the target solution just injected, which is measured by the first temperature sensor 25, cannot represent the temperature of the entire target solution, and the detection result is unreliable. In the present embodiment, the first temperature sensor 25 is disposed at the bottom of the accommodating chamber 211, which helps to improve the reliability of the detection of the temperature of the target solution.
During the dyeing process, the temperature of the target solution is generally high, and in order to protect the pressure sensor 23 from being damaged by high temperature, it is generally necessary to cool the pressure sensor 23. The temperature control assembly 30 is mounted to the frame 10 and may be used to cool the pressure sensor 23.
