Description

Densitometer

The present invention relates to a densitometer.

Densitometers are instruments that measure the concentration of liquids.

Specifically, the method of measuring the concentration is classified into a titration method using chemical properties, a conductivity measurement method using current intensity, an optical measurement method using light transmittance, and the like, and a density measurement method using density.

The most common method is density measurement, which is a method of calculating the concentration by measuring the density of a liquid. Density measurement method uses a hydrometer (Hydrometer, 液體 比重 計) and the like. The liquid hydrometer has an advantage of a simple measuring method and a relatively fast measuring speed. In addition, it can measure up to 0.0002 specific gravity, so the accuracy is also high.

However, the hydrometer according to the prior art, as disclosed in the patent document of the following prior art document, the visual contact with the interface of the liquid should be visually confirmed, so there is a restriction in use. In addition, hydrometers can only express concentrations visually, they do not express concentrations audibly. In addition, there is a problem that the hydrometer cannot express a trend of increasing concentration or a trend of falling concentration.

It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. In addition, terms such as “first” and “second” are used to distinguish one component from another component, and the component is not limited by the terms. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram of a concentration meter according to a preferred embodiment of the present invention, Figures 2 to 3 are plan views of the first conducting member and the second conducting member shown in FIG.

As shown in FIG. 1, the concentration measuring device 100 according to the present embodiment includes a first container 110, an induction plate 130, a support part 117, a second container 120, a weight 115, and rotation. The member 140, the protrusion 125, the rotating part 147, the spring 149, the first conducting member 150, the second conducting member 170, the controller 180, and the speaker 190 are included.

The first container 110 has a fluid flowing in a predetermined direction therein, and has a rectangular parallelepiped shape as a whole. Specifically, the first container 110 is provided with an inlet 111 on one side, the outlet 113 is provided on the other side. Accordingly, the fluid flows in from the inlet 111 and flows out of the outlet 113. However, when the flow velocity of the fluid is large, when the weight 115 is moved up and down depending on the concentration of the fluid, it may have an unnecessary effect on the weight (115). Therefore, in order to prevent the weight 115 from being affected by the flow velocity of the fluid as much as possible, the first container 110 may be provided with an induction plate 130. Here, the induction plate 130 alternately protrudes from the upper and lower surfaces of the first container 110 to induce the fluid flowing from the inlet 111 to zigzag in the vertical direction. When the fluid flows zigzag due to the induction plate 130, since the flow velocity of the fluid is lowered, it is possible to prevent the weight 115 from being affected by the flow velocity of the fluid. On the other hand, the inside of the first container 110 is provided with a support portion 117 for supporting the weight (115). Here, the support 117 is provided between the guide plate 130 and the outlet 113, and extends in a cylindrical shape from the lower surface to the upper surface of the first container (110). The weight 115 may be provided inside the support 117. Here, the weight 115 is moved up and down of the support 117 according to the concentration of the fluid. That is, as the concentration of the fluid increases, the weight 115 moves upward while the buoyancy becomes stronger, and as the concentration of the fluid decreases, the weight 115 decreases while the weight 115 moves downward. At this time, the weight 115 is formed in a cylindrical shape to correspond to the support portion 117 is supported by the support portion 117. Therefore, the weight 115 can be prevented from moving back, front, left, and right while moving up and down. In addition, as shown in FIG. 6, the support part 117 is formed with a guide part 117a in which metal is removed in a straight line along the side of the mesh shape, and the guide part of the support part 117 is provided on the side surface of the weight 115. Protruding portion 115a is formed to be inserted into 117a. As such, since the protrusion 115a of the weight 115 is inserted into the guide part 117a of the support part 117, the weight 115 can be prevented from being rotated while moving up and down. On the other hand, when the density of the fluid becomes very high and the density of the fluid becomes larger than the density of the weight 115, the weight 115 rises up to the surface of the fluid, making it impossible to measure the concentration of the fluid. Therefore, the weight 115 is preferably formed of high density osmium (osmium). However, the weight 115 is not necessarily formed of osmium, of course, may be formed of a metal having a density of a certain degree or more.

 In addition, the second container 120 (refer to FIG. 1) extends upwardly so as to communicate with the first container 110, and is provided above the support part 117, and has a circular cross section. The rotating member 140 is provided inside the second container 120. Here, the rotating member 140 is connected to the weight 115 and the seal 146, and is provided with an elastic force in the upward direction by the spring 149. Therefore, as the concentration of the fluid increases, the weight of the weight 115 decreases relatively as the buoyancy becomes stronger, so that the rotating member 140 moves upward with the weight 115 by the elastic force of the spring 149 ( Weight of the weight 115 <elastic force of the spring 149). Conversely, when the concentration of the fluid is lowered, the weight of the weight 115 is relatively increased while the buoyancy is weakened, so that the rotating member 140 moves downward with the weight 115 by the weight of the weight 115. (Weight of weight 115> elastic force of spring 149). That is, when the concentration of the fluid is increased, the rotating member 140 is moved upward by a predetermined range, and when the concentration of the fluid is lowered, the rotating member 140 is moved downward by a predetermined range. In addition, since the concentration measuring device 100 according to the present invention measures the concentration while the fluid flows in from the inlet 111 to the outlet 113, it is possible to continuously measure the concentration of the fluid. That is, even if the concentration changes with the flow of the fluid, the concentration of the fluid can be continuously measured accordingly. On the other hand, the rotating member 140 is formed with a groove portion 145 spirally recessed along the outer circumferential surface, the protrusion 125 protruding inward from the second container 120 is inserted into the groove portion 145. Therefore, when the concentration of the fluid is increased and the rotating member 140 is moved upward, the rotating member 140 is rotated in one direction by the protrusion 125 inserted into the groove 145 recessed in a spiral shape. Conversely, when the concentration of the fluid is lowered and the rotating member 140 is moved downward, by the protrusion 125 inserted into the groove 145 recessed in a spiral, the rotating member 140 is in the other direction (the direction opposite to the one direction). Rotated). As such, when the rotating member 140 is rotated, the spring 149 connected to the rotating member 140 may be twisted. In order to prevent this, the spring 149 is coupled to the rotating part 147. Specifically, the rotating unit 147 may be provided on the upper end of the second container 120, and may rotate based on the central axis of the second container 120. Therefore, even when the rotating member 140 rotates, the spring 149 rotates together with the rotating part 147, so that it is not twisted. Here, the rotating unit 147 is not particularly limited, but may be rotated together with the rotating member 140 by being coupled to the upper end of the second container 120 through a ball bearing (see FIGS. 4 to 5).

On the other hand, among the outer circumferential surface of the rotating member 140, a number that increases toward the lower side along the groove portion 145 recessed in a spiral is described. At this time, the number indicates the concentration of the fluid. In this regard, the outer circumferential surface of the second container 120 is provided with a display unit 127 that is displayed in a box shape. Here, the box-shaped display unit 127 surrounds a specific number among the numbers described on the rotating member 140, and the specific number indicates the concentration of the fluid. Of course, in order for the specific number surrounded by the display unit 127 to accurately display the current concentration of the fluid, it is necessary to adjust the position of the rotating member 140 or the position of the number described in the rotating member 140 in the manufacturing process. . For example, the position of the rotating member 140 or the position of the number described on the rotating member 140 to be a specific number "0" surrounded by the display unit 127 while flowing pure water (Pure Water) as a fluid Can be adjusted.

On the other hand, since the numbers are described along the helical recessed grooves 145, the numbers also spiral. Therefore, many numbers can be described within a relatively short width, and since the numbers finally express the concentration of the fluid, the concentration meter 100 according to the present embodiment can accurately express the concentration of the fluid.

In addition, the first conducting member 150 may be coupled to the rotating member 140. Specifically, the first conducting member 150 is bent vertically at the end of the extension portion 150a and the extension portion 150a extending upward from the upper surface of the rotating member 140 to the outer side of the second container 120. Extended contact portion 150b. That is, the first conducting member 150 is an extension portion 150a and the contact portion 150b is formed in a "-" shape. Here, since the first conducting member 150 is fixed to the rotating member 140, it is rotated while moving up and down with the rotating member 140. In this case, in order to rotatably support the first conducting member 150, a bearing 129 may be provided at an upper end of the second container 120. In addition, when the first conducting member 150 is rotated to be in contact with the second conducting member 170 as it rotates, and the first conducting member 150 and the second conducting member 170 in contact with the speaker 190 is a control unit. Receives an electrical signal of 180 and outputs a specific sound, which will be described in detail later.

On the other hand, a shaft 160 extending parallel to the extension portion 150a of the first conducting member 150 is disposed on one side of the first container 110. Here, the shaft 160 may be fixed to the base substrate 300 together with the first container 110. In addition, the shaft 160 is coupled to the second conducting member 170 in contact with the contact portion 150b of the first conducting member 150. Specifically, the second conducting member 170 is formed in a rod shape, the first conducting member 150 may be rotated to contact. In addition, as shown in FIGS. 2 to 3, the second conducting member 170 is coupled to the shaft 160 to rotate a predetermined angle with respect to the shaft 160. Therefore, when the first conducting member 150 contacts the second conducting member 170, the second conducting member 170 is rotated by a predetermined angle with respect to the shaft 160. 2, the rotating member does not stop due to the energizing member 170, it can continue to rotate (see Fig. 2b or 3b). In addition, an end of the contact portion 150b of the first conducting member 150 may be rounded to smoothly contact the second conducting member 170, and the first conducting member 150 may be removed from the second conducting member 170. After being separated, the shaft 160 may be provided with an elastic member such as a twist spring so that the second conducting member 170 returns to its original position. On the other hand, the plurality of second conducting member 170 is provided in parallel along the axis 160 direction (see Fig. 1). Therefore, the first conducting member 150 is moved up and down and rotates to contact the plurality of second conducting members 170, respectively. That is, the first conducting member 150 moves upward and downward, and contacts the second conducting members 170 different from each other. This configuration is to allow the controller 180 to output information about the concentration of the fluid to the speaker 190 as a sound, which will be described later. On the other hand, the second conducting member 170 is laminated in the order of the first conducting portion 170a, the insulating portion 170b and the second conducting portion 170c in the thickness direction (see FIGS. 2 to 3). Here, the first conducting unit 170a and the second conducting unit 170c are in contact with the first conducting member 150. Specifically, the first conducting member 150 is in contact with one of the first conducting unit 170a and the second conducting unit 170c according to the rotation direction of the first conducting member 150. In addition, the insulating unit 170b insulates the first conducting unit 170a and the second conducting unit 170c from each other. According to the rotation direction of the first conducting member 150, the configuration in which the first conducting member 150 contacts the first conducting unit 170a or the second conducting unit 170c is controlled by the controller 180 as the speaker 190. It is to output the information about the concentration rise / fall of the fluid to a negative, a detailed description will be described later.

The controller 180 is electrically connected to the first conducting member 150 and the second conducting member 170, and the speaker 190 is contacted with each other when the first conducting member 150 and the second conducting member 170 contact each other. By transmitting an electrical signal to the speaker 190 to output information about the concentration or information about the concentration rise / fall concentration as a sound. Specifically, when the first conducting member 150 is rotated while moving up and down, and contacts the second conducting member 170 provided with a plurality along the axis 160 direction, respectively, the controller 180 is the first conducting member Each time 150 contacts each second conducting member 170, a different electrical signal (concentration related electrical signal) is transmitted to the speaker 190. At this time, the speaker 190 receives an electrical signal (concentration related electrical signal) from the controller 180, and outputs information about the concentration as a sound. In addition, when the first conducting member 150 is defined as being rotated while moving upward, one direction, the first conducting member 150 is moved downward due to the spiral groove 145 formed in the rotating member 140. While rotating in the other direction (one direction and the opposite direction). Based on this configuration, when the first conducting member 150 is rotated in one direction while moving upward, the first conducting member 150 contacts the first conducting unit 170a of the second conducting member 170 ( 2a). Since the concentration of the first conducting member 150 is moved upward, the controller 180 increases the electric signal (concentration) when the first conducting member 150 contacts the first conducting unit 170a. A rise-related electrical signal) to the speaker 190. The speaker 190 receives an electrical signal (concentration increase related electrical signal) from the controller 180 and outputs information on the concentration increase as a sound. On the contrary, when the first conducting member 150 is rotated in the other direction while being moved downward, the first conducting member 150 contacts the second conducting unit 170c of the second conducting member 170 (see FIG. 3A). ). Since the concentration of the first conducting member 150 moves downward, the control unit 180 controls the electric signal (concentration) when the first conducting member 150 contacts the second conducting unit 170c. The electrical signal related to falling) is transmitted to the speaker 190. The speaker 190 receives an electric signal (concentration drop related electric signal) from the controller 180 and outputs information on the concentration drop as a sound. Therefore, the concentration measuring apparatus 100 according to the present embodiment may not only express the concentration, but may also express the trend of increasing the concentration or the trend of decreasing the concentration.

In addition, the concentration measuring apparatus 100 according to the present exemplary embodiment may include the speed measuring unit 215 (see FIG. 1) using the rotation of the rotating member 140 to express the speed at which the concentration of the fluid rises or falls. 4 to 5 are enlarged views of a portion A shown in FIG. 1. 4 to 5, the upper side of the second container 120 is provided with a shaft 220 extending in parallel with the extension portion 150a. Here, the shaft 220 is connected to the extension portion 150a and the gear 221. Therefore, when the extension part 150a is rotated as the rotating member 140 is rotated, the shaft 220 connected to the extension part 150a and the gear 221 is also rotated. The shaft 220 has a first collar (223, First Collar) is fixed to the top, the second collar (225, Second Collar) is coupled to be moved up and down along the shaft 220 at the bottom, the first An elastic member 227 is provided between the collar 223 and the second collar 225. In addition, the mass body 230 is coupled to the first collar 223 and the second collar 225 by a link 235. Here, the coupling portion of the link 235 is coupled to the first collar 223, the second collar 225, and the mass 230 to be rotatable. Therefore, as shown in FIG. 4, when the rotational speed of the extension part 150a is increased, the rotational speed of the shaft 220 is also increased, whereby the centrifugal force acting on the mass body 230 is increased by the elastic member 227. Since it is larger than the elastic force, as the second collar 225 moves upward, the mass body 230 moves away from the shaft 220. Conversely, as shown in FIG. 5, when the rotational speed of the extension part 150a decreases, the rotational speed of the shaft 220 also decreases, so that the elastic force of the elastic member 227 acts on the mass body 230. Since the second collar 225 is moved downward, the mass body 230 is brought closer to the shaft 220. As a result, the faster the rotational speed of the extension 150a, the farther the mass body 230 is from the shaft 220, and the slower the rotational speed of the extension 150a, the closer the mass body 230 is from the shaft 220. Lose. Here, the rotational speed of the extension part 150a is the same as the rotational speed of the rotating member 140, and the rotational speed of the rotating member 140 is proportional to the speed at which the concentration of the fluid rises or falls. Therefore, the speed at which the concentration of the fluid rises or falls can be confirmed by observing the degree to which the mass body 230 moves away from the shaft 220. On the other hand, since centrifugal force is generated on the mass body 230 only by transmitting a sufficient rotational speed to the shaft 220, the gear 221 of the shaft 220 is preferably smaller in diameter than the gear 221 of the extension portion 150a. Do.

On the other hand, the surface of the first container 110 is provided with a dye-sensitized solar cell 200 (see Fig. 1), the storage unit 210, such as a battery for storing the electrical energy generated by the dye-sensitized solar cell 200 ) May be provided. Here, the dye-sensitized solar cell 200 generates electrical energy from sunlight, and the electric energy generated by the dye-sensitized solar cell 200 is stored in the storage unit 210. As such, the electrical energy stored in the storage unit 210 may be supplied to the controller 180 and the speaker 190. In particular, the electrical energy of the storage 210 may be used to output a specific sound to the speaker 190 according to the electrical signal of the controller 180. On the other hand, the dye-sensitized solar cell 200 uses a nano-sized dye molecules such as titanium dioxide (TiO ₂ ). Specifically, when sunlight is absorbed by the nanoparticle semiconductor oxide electrode chemically adsorbed with dye molecules on the surface, the dye molecules give up electrons, which are transferred to the transparent conductive substrate through various paths, and finally energy is generated. do. The dye-sensitized solar cell 200 realizes an efficiency similar to that of a conventional silicon solar cell, but has only one third to one fifth manufacturing cost compared to a silicon solar cell, and thus has an excellent price competitiveness. In addition, since the dye-sensitized solar cell 200 can generate energy irrespective of the incident angle of sunlight, even when installed in the first container 110 having a limited installation angle, the energy can be sufficiently generated. In addition, since the dye-sensitized solar cell 200 uses dye molecules having a selective light absorption band for the visible part, it is possible to implement transparent color characteristics. Therefore, even if the dye-sensitized solar cell 200 is installed in the first container 110, transparency can be maintained, so that the movement of the weight 115 provided inside the first container 110 can be confirmed. Accordingly, various colors may be implemented in the first container 110.

7 to 8 are conceptual views illustrating a process of operating the concentration meter shown in FIG.

First, referring to Figure 7, when the concentration rises to 20%, look at the process of operating the concentration measuring device 100 according to this embodiment. As the concentration of the fluid rises, the weight of the weight 115 decreases relatively as the buoyancy becomes stronger. Therefore, since the elastic force of the spring 149 is greater than the weight of the weight 115, the rotating member 140 is moved upward with the weight 115 by the elastic force of the spring 149. At this time, since the protrusion 125 is inserted into the groove 145 of the spiral, the rotating member 140 is rotated while moving upward. In addition, the number described on the outer circumferential surface of the rotating member 140 also rotates, and stops when the elastic force of the spring 149 is equal to the weight of the weight 115. As such, the specific number surrounded by the display unit 127 in the stopped state means the current concentration (20%). On the other hand, since the rotating member 140 is rotated while moving upward, the first conducting member 150 coupled to the rotating member 140 is also rotated in one direction while moving upward, among the plurality of second conducting members 170 The second contact member 170 ′ is contacted with the specific second conducting member 170 ′. As such, when the first conducting member 150 contacts the specific second conducting member 170 ′, the controller 180 transmits an electrical signal (concentration related electrical signal) to the speaker 190, and the speaker 190. Receives this information and outputs the concentration-related information as a negative. For example, the speaker 190 may output a sound that "the current concentration is 20%". In addition, when the concentration is increased, since the first conducting member 150 is rotated in one direction, the first conducting member 150 contacts the first conducting unit 170a of the specific second conducting member 170 '(see FIG. 2A). As such, when the first conducting member 150 contacts the first conducting unit 170a, the controller 180 transmits an electrical signal (concentration-related electrical signal) to the speaker 190, and the speaker 190 Receives this information and outputs the concentration increase information as a negative. For example, the speaker 190 may output a sound called "concentration rise". However, the controller 180 does not have to transmit the above-mentioned two electrical signals (concentration related electrical signals and concentration increase related electrical signals) to the speaker 190 separately, but may transmit them to the speaker 190 at the same time. In this case, the speaker 190 may receive two electric signals (concentration related electric signals and concentration increase related electric signals), and output a sound of "the current concentration is 20% and the concentration increases".

On the other hand, referring to Figure 8, when the concentration drops to 12%, look at the process of operating the concentration measuring device 100 according to this embodiment. As the concentration of the fluid is lowered, the weight of the weight 115 increases relatively as the buoyancy weakens. Therefore, since the weight of the weight 115 is greater than the elastic force of the spring 149, the rotation member 140 is moved downward with the weight 115 by the weight of the weight (115). At this time, since the protrusion 125 is inserted into the groove 145 of the spiral, the rotating member 140 is rotated while moving downward. In addition, the number described on the outer circumferential surface of the rotating member 140 is also rotated, and stops when the weight of the weight 115 is equal to the elastic force of the spring 149. In this way, the specific number surrounded by the display unit 127 in the stopped state means the current concentration (12%). On the other hand, since the rotating member 140 is rotated while moving downward, the first conducting member 150 coupled to the rotating member 140 is also rotated in the other direction while moving downward, a plurality of second conducting member 170 The second conductive member 170 'is contacted. As such, when the first conducting member 150 contacts the specific second conducting member 170 ′, the controller 180 transmits an electrical signal (concentration related electrical signal) to the speaker 190, and the speaker 190. Receives this information and outputs the concentration-related information as a negative. For example, the speaker 190 may output a sound of "current concentration is 12%". In addition, when the concentration decreases, since the first conducting member 150 rotates in the other direction, the first conducting member 150 contacts the second conducting unit 170c of the specific second conducting member 170 '(see FIG. 3A). As such, when the first conducting member 150 contacts the second conducting unit 170c, the controller 180 transmits an electric signal (concentration drop related electric signal) to the speaker 190, and the speaker 190 It receives this and outputs the concentration-related information in a negative way. For example, the speaker 190 may output a sound of "falling concentration". However, the controller 180 does not necessarily transmit the above-mentioned two electrical signals (concentration-related electrical signals and concentration-lowering-related electrical signals) to the speaker 190 separately, but may transmit them to the speaker 190 at the same time. In this case, the speaker 190 may receive two electrical signals (concentration-related electrical signals and concentration drop-related electrical signals) and output a sound of "the current concentration is 12% and the concentration drops".

In addition, while the concentration measuring device 100 according to the present embodiment operates as described above, the velocity measuring unit 215 may also measure the speed at which the concentration of the fluid rises or falls.

Meanwhile, the controller 180 and the speaker 190 may be operated by receiving electrical energy from the storage 210. Here, the electrical energy stored in the storage unit 210 may be generated in the dye-sensitized solar cell 200.

As described above, the concentration measuring apparatus 100 according to the present exemplary embodiment may visually express the concentration of the fluid using the numbers described on the rotating member 140 and the display unit 127 provided in the second container 120. In addition, the speaker 190 may be used to express the concentration of the fluid acoustically. In addition, by using the first conducting member 150 having a different rotation direction in accordance with the rise and fall of the concentration, the speaker 190 may express the trend of increasing the concentration or decreasing the concentration. In addition, the velocity measuring unit 215 may be used to express the velocity at which the concentration of the fluid rises or falls.
