DETAILED DESCRIPTION

[0033] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0034] The following is combined with Figure 1-9 The utility model is described in further detail.

[0035] Reference Figure 1 , Figure 2 and Figure 3 In the description of the utility model, the utility model provides an ultrasonic liquid phase analyzer, including a connecting pipe 1, a connecting piece 2 is provided on the outer peripheral surface of the connecting pipe 1, an analyzer body 3 is installed above the connecting piece 2, a display screen 9 is provided at the front end of the analyzer body 3, an ultrasonic sensor 5 is provided on the inner side wall of the connecting pipe 1, the ultrasonic sensor 5 includes an ultrasonic transmitter 51 and an ultrasonic receiver 52, the ultrasonic sensor 51 and the ultrasonic receiver 52 are arranged opposite to each other, a temperature sensor 6 is provided on the top of the inner wall of the connecting pipe 1, connecting flanges 7 are fixedly installed at both ends of the connecting pipe 1, and a current limiting component 9 is provided at the output end of the connecting pipe 1.

[0036] When the liquid flows through the connecting pipe 1 of the ultrasonic liquid phase analyzer, the ultrasonic transmitter 51 emits a beam of ultrasonic signal. The signal reaches the ultrasonic receiver 52 on the opposite side after passing through a certain concentration of liquid, so as to measure the total time of ultrasonic signal transmission. The distance divided by the time is the ultrasonic sound velocity. The temperature sensor 6 is responsible for measuring the liquid temperature. When the concentration or density remains unchanged, the propagation speed of the ultrasonic signal in the liquid medium will be affected by the temperature. Depending on the medium, the size and trend of the impact on the sound velocity are also different. The processor in the instrument will analyze the liquid phase according to the measured sound velocity and temperature, and divide the liquid phase into heavy phase, intermediate phase and light phase and display them on the display screen 9.

[0037] Reference Fig. 9 The flow limiting assembly 9 includes a fixed ring 91, a flow limiting blade 92, a driving belt 93 and a driving wheel 94. The fixed ring 91 is installed at one end of the connecting pipe 1. A flow channel 95 is provided in the center of the fixed ring 91. A rotating shaft 911 is equidistantly provided on the fixed ring 91. A rotating ring 921 is provided at one end of the flow limiting blade 92. The rotating ring 921 is sleeved on the rotating shaft 911. The driving belt 93 is attached to the outer side of the rotating ring 921. The driving wheel 94 is rotatably connected to the fixed ring 91. A rotating rod 941 is provided in the middle of the driving wheel 94. The outer side of the driving wheel 94 is attached to the driving belt 93. A current limiting motor 96 is provided above the fixed ring 91. The rotating rod 941 is connected to the rotating shaft of the current limiting motor 96 through a belt.

[0038] When the liquid phase analyzer detects a change in the liquid phase, the current limiting motor 96 is started, and the shaft of the current limiting motor 96 drives the rotating rod 941 to rotate through the belt, and the rotation of the rotating rod 941 drives the driving wheel 94 to rotate, and the driving wheel 94 drives the rotating ring 921 to rotate through the driving belt 93, and the rotating ring 921 drives the rotating shaft 911 to rotate, and the rotating shaft 911 drives the opening and closing of the current limiting blade 92. The opening and closing of the current limiting blade 92 reduces the inner diameter of the flow channel 95. The reduction in the inner diameter reduces the flow rate of the liquid, making the separation of the liquid phase more accurate and improving the extraction accuracy. After a certain period of time, the current limiting motor 96 reverses and the current limiting blade 92 is reset. The circulation channel 95 returns to its original state.

[0039] Reference Figure 4 and Figure 5The heat dissipation mechanism 4 includes a driving motor 41, a left rotating shaft 42, a right rotating shaft 43, an axle connection assembly 44, a clamping assembly 45, a cross mounting frame 46, a fan blade 47 and a rear shell 48.

The fan blade 43 is provided on the right rotating shaft 43. The right rotating shaft 43 is connected to the rear shell 48 through a bearing, and the rear shell 48 is connected to the analyzer body 3 through the clamping assembly 45.

[0040] When the temperature of the components in the analyzer body 3 rises, the drive motor 41 on the cross mounting bracket 46 starts, and the output shaft of the drive motor 41 drives the left rotating shaft 42 to rotate, and the left rotating shaft 42 drives the right rotating shaft 43 to rotate, and the rotation of the right rotating shaft 43 drives the fan blades 47 to rotate. The rotation of the fan blades 47 drives the flow of air, thereby cooling the components with increased temperature. The shaft connection assembly 44 is used to connect the left rotating shaft 42 and the right rotating shaft 43, and the clamping assembly 45 is used to connect the analyzer body 3 and the rear shell 48.

[0041] Reference Figure 6 The shaft connection assembly 44 includes a spring groove 441, a rolling ball 442, a spring 443, a plug-in groove 444, a clamping block 445 and an arc groove 446.

The clamping block 445 is inserted into the plug-in groove 444.

[0042] When it is necessary to separate the left rotating shaft 42 and the right rotating shaft 43, the right rotating shaft 43 is pulled away from the left rotating shaft 42, and the rolling ball 442 squeezes the spring 443 to shrink it, and the rolling ball 442 slides off the arc groove 446, and the clamping block 445 leaves the plug-in groove 444, and the left rotating shaft 42 and the right rotating shaft 43 are separated.

[0043] Reference Figure 7The snap-on assembly 45 includes a receiving groove 451, a reset spring 452, a connecting block 453 and a pressing key 454. A receiving chamber 455 is provided on the inner circumference of the analyzer body 3. A snap-on groove 456 is provided in the receiving chamber 455. The receiving groove 451 begins to be provided in the side wall of the rear shell 48. The reset spring 452 is placed in the receiving groove 451. The connecting block 453 is connected above the reset spring 452. A protrusion 457 is provided at one end of the connecting block 453. The protrusion 457 fits with the snap-on groove 456. The pressing key 454 is provided at the other end of the connecting block 453. One end of the pressing key 454 is provided on the outside of the rear shell 48.

[0044] When the rear shell body 48 needs to be removed, the push button 454 is pressed, and the push button 454 drives the connecting block 453 to move downward, the return spring 452 is deformed by force, and the protrusion 457 disengages from the snap-in groove 456. At this time, the connecting block 453 leaves the accommodating chamber 455, and the rear shell body 48 is removed. When the rear shell body 48 needs to be installed, the push button 454 is pressed, and the push button 454 drives the connecting block 453 to move downward, the return spring 452 is deformed by force, and the connecting block 453 extends into the accommodating chamber 455. The pressed push button 454 is released, and the return spring 452 resets and lifts the connecting block 453, and the protrusion 457 is snapped into the snap-in groove 456, and the rear shell body 48 is installed.

[0045] Reference Figure 4 A heat dissipation net 458 is provided on one side of the rear housing 48. The heat emitted by the instrument is discharged from the heat dissipation net 458.

[0046] Reference Figure 5 A temperature control sensor 8 is provided in the analyzer body 3, and the temperature control sensor 8 controls the speed of the driving motor 41 and the start and stop of the motor.

[0047] The temperature control sensor 8 monitors the temperature of the components in the instrument. When the temperature reaches the starting threshold, the drive motor 41 starts to dissipate heat. The temperature control sensor 8 transmits the temperature change to the microprocessor. When the temperature is high, the speed of the drive motor 41 increases, and when the temperature is low, the speed of the drive motor 41 slows down. When the temperature is lower than the threshold, the drive motor 41 stops running. Adjusting the speed of the motor according to the temperature can save energy and thus reduce energy consumption.

[0048] Reference Figure 1 and Figure 2 The display screen is a touch screen. The touch screen can display the state of the liquid phase (light phase, middle phase, heavy phase), and operations can be performed directly on the interface.

[0049] Reference Figure 3 The ultrasonic receiver 51 and the ultrasonic transmitter 52 have the same structure.

[0050] Reference Figure 8 , This application provides a partial liquid phase test data table, and the liquid phase can be analyzed based on the sound velocity.

[0051] Working principle: When the liquid flows through the connecting pipe 1 of the ultrasonic liquid phase analyzer, the ultrasonic transmitter 51 emits a beam of ultrasonic signal. The signal reaches the ultrasonic receiver 52 on the opposite side after passing through a certain concentration of liquid, so as to measure the total time of ultrasonic signal transmission. The distance divided by the time is the ultrasonic sound velocity. The temperature sensor 6 is responsible for measuring the liquid temperature. When the concentration or density remains unchanged, the propagation speed of the ultrasonic signal in the liquid medium will be affected by the temperature. Depending on the medium, the magnitude and trend of the impact on the sound velocity are also different. The liquid phase data corresponding to different temperatures and sound velocities are stored in the database. The processor in the instrument will compare and analyze the measured sound velocity and temperature in the database, and divide the liquid phase into heavy phase, intermediate phase and light phase and display them on the display screen 9.
