Description

Technical Field

[0001] The utility model relates to the technical field of instruments and meters, in particular to an ultrasonic alcohol concentration meter. Background Art

[0002] An ultrasonic concentration meter is a measuring instrument that uses ultrasonic technology to measure the concentration of solutes in a fluid (such as impurities, particulate matter, bubbles, etc. in liquids or gases). The operating principle of an ultrasonic concentration meter is that an ultrasonic transmitting probe transmits a beam of ultrasonic signals. After the signal passes through a liquid of a certain concentration, it reaches another ultrasonic receiving probe on the opposite side, thereby measuring the total time of ultrasonic signal transmission. The distance divided by the time is the ultrasonic sound velocity, and the change in the propagation speed of the ultrasonic wave is used to calculate the concentration.

[0003] The ultrasonic concentration meters currently on the market have the following problems when used in the liquor brewing process. Because the liquor is collected by gravity in the steamer barrel, the liquor flows in the pipe in a state of not full pipe, and the instrument cannot perform measurement work in the state of not full pipe.

[0004] Therefore, the present application provides an ultrasonic alcohol concentration meter. Utility Model Content

[0031] 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.

[0032] The following is combined with Figure 1-9 The utility model is described in further detail.

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Fig. 9In the description of the utility model, the utility model provides an ultrasonic alcohol concentration meter, including a measuring pipe 1, a measuring fixture 2 is installed on the upper end of the measuring pipe 1, a connecting member 3 is installed above the measuring fixture 2, a display member 4 is installed above the connecting member 3, an instrument panel 41 is provided on the outer surface of the display member 4, and a power supply 8 and a control module 9 are provided in the shell of the display member 4, A detection device 5 is provided in the measuring pipeline 1, and the detection device 5 is located directly below the measuring fixture 2. The detection device 5 includes an ultrasonic sensor 51 and a temperature sensor 52. The ultrasonic sensor 51 is provided on the inner wall of the measuring pipeline 1 and connected to the bottom of the measuring pipeline 1. The ultrasonic sensor 51 includes an ultrasonic transmitter 511 and an ultrasonic receiver 512. The ultrasonic transmitter 511 and the ultrasonic receiver 512 are arranged opposite to each other. The ultrasonic sensor 51 and the temperature sensor 52 are electrically connected to the control module 9 respectively, the display unit 4 is electrically connected to the control module 9, the power supply 8 is electrically connected to the display unit 4, the control module 9 and the detection device 5 respectively, and mounting flanges 7 are provided at both ends of the measuring pipeline 1.

[0034] The wine to be measured enters the measuring pipe 1 from one side of the measuring pipe 1. Since the ultrasonic sensor 51 is arranged at the lower side of the measuring pipe 1, the ultrasonic sensor 51 with a sunken design ensures that even if the wine is not full, the ultrasonic sensor 51 will be completely immersed in the wine to be measured, ensuring that the concentration meter measurement can be carried out smoothly. The control module 9 drives the ultrasonic generator 511 to generate a beam of ultrasonic signals. The ultrasonic signal reaches the ultrasonic receiver 512 on the opposite side after passing through a liquid of a certain concentration, so as to measure the total time of ultrasonic signal transmission. The distance divided by the time is the ultrasonic sound speed. The temperature sensor 52 is used to detect the temperature of the wine. The control module 9 is responsible for the generation, reception and calculation of the concentration meter signal. The calculated result is displayed on the display screen. Within a certain concentration range, the propagation speed of the ultrasonic signal in the liquid medium is a function of the concentration and temperature. The ultrasonic detection is not affected by the turbidity, chromaticity and conductivity of the medium, nor is it affected by the flow state and impurities. The built-in high-precision thermal resistor temperature measuring element and the durable sensor design ensure the real-time accuracy of the instrument.

[0035] Reference Figure 8 , the control module includes a control circuit 91 and a microprocessor 92.

[0036] The control circuit 91 is used to control the generation and reception of ultrasonic signals and to receive signal data obtained by the temperature sensor 52. The microprocessor 92 processes the received signals and displays them on the display screen.

[0037] Reference Figure 2A liquid inlet pipe 10 is provided on one side of the measuring pipe 1, and the liquid inlet pipe 10 forms an angle of 30° with the horizontal plane.

[0038] The inclined liquid inlet pipe 10 introduces the wine body into the sensor part first, ensuring that the wine body can submerge the sensor part and ensure the normal operation of the ultrasonic concentration meter.

[0039] Reference Figure 4 and Figure 5 An auxiliary detection device 6 is also provided on one side of the detection device 5, and the auxiliary detection device includes a connecting rod 61, a wiring groove 62, a firing cavity 63, an auxiliary ultrasonic transmitter 64 and an auxiliary ultrasonic receiver 65. The connecting rod 61 is arranged on the inner wall of the measuring pipeline 1 along the fluid direction, and the auxiliary ultrasonic transmitter 64 and the auxiliary ultrasonic receiver 65 are respectively provided at both ends of the connecting rod 61. The firing cavity 63 is opened between the auxiliary ultrasonic transmitter 64 and the auxiliary ultrasonic receiver 65, and the wiring groove 62 is opened in the connecting rod 61. The auxiliary detection device 6 is electrically connected to the control module.

[0040] The auxiliary ultrasonic transmitter 64 generates an ultrasonic signal, and the auxiliary ultrasonic receiver 65 receives the ultrasonic signal to measure the concentration information of the wine in the emission cavity 63. The auxiliary detection device 6 is used to measure the alcohol concentration in the horizontal direction. The auxiliary detection device 6 can compare and verify the concentration data measured by the detection device 5 to ensure the accuracy of the ultrasonic concentration meter.

[0041] Reference Figure 3 The instrument panel 41 is provided with a display screen 411 and buttons 412 .

[0042] The display screen 411 on the surface panel 41 can conveniently and intuitively display the concentration information in the tube in real time, and the button 412 is convenient for the staff to operate the ultrasonic concentration meter.

[0043] Reference Figure 8 , the microprocessor 92 is a single chip microcomputer.

[0044] A single-chip microcomputer is a small and complete microcomputer system that uses very large-scale integrated circuit technology to integrate a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt system, timer / counter and other functions onto a single silicon chip. It is widely used in the field of industrial control.

[0045] Reference Figure 6 A waste outlet is also provided on the side wall of the measuring pipe 1.

[0046] Reference Figure 1 , the electrical connection wire is a coaxial shielded wire.

[0047] Coaxial shielded cables use the external armor shielding performance to isolate signals and interference. The electromagnetic wave signals of the internal wires of the coaxial transmission line are transmitted under the copper foil shielding wrapped around the center conductor. The outer conductor absorbs the electromagnetic wave signals of external interference by contacting the ground, ensuring the reliable signal transmission inside the coaxial transmission line. The coaxial shielded cable has a simple and durable structure and good shielding performance. Since the coaxial shielded cable has many shielding layers, the loss of electromagnetic wave signals is relatively small during the transmission process of the transmission line, and the transmission efficiency is higher.

[0048] Working principle: the wine to be tested enters the measuring pipe 1 from one side of the measuring pipe 1, the ultrasonic sensor 51 is immersed in the wine to be tested, and the control module 9 drives the ultrasonic generator 511 to generate a beam of ultrasonic signals. The ultrasonic signal passes through a liquid of a certain concentration and reaches the ultrasonic receiver 512 on the opposite side, so as to measure the total time of ultrasonic signal transmission. The distance divided by the time is the ultrasonic sound speed. The temperature sensor 52 is used to detect the temperature of the wine. Within a certain concentration range, the propagation speed of the ultrasonic signal in the liquid medium is a function of the concentration and temperature. After calculation by the microprocessor, the concentration of the wine is obtained, and the result of the calculation will be displayed on the display.
