Description

Technical Field

[0001] The present application relates to the technical field of blending devices, and in particular to a concentrated solution blending device based on a urea concentration sensor. Background Art

[0002] A blending device is a device used to mix or blend different components or substances. It typically includes functions such as stirring, mixing, and homogenization to ensure the uniformity of the mixture's composition. Such devices are widely used in the chemical, pharmaceutical, and food processing industries to achieve desired product specifications and quality. The design and type of blending device can vary depending on the properties of the mixture, production needs, and process requirements. Existing urea concentrate blending devices are unable to detect the urea solution mixed in the pipeline mixer in real time, making it impossible to monitor the density of the urea solution in real time. Manual operation can result in significant errors, reducing the accuracy of the measurement.

[0003] Therefore, we propose a concentrated liquid blending device based on urea concentration sensor to solve this problem.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application.

An installation box 5 is fixedly installed on one side of the bracket 1, and an ultrasonic sensor 14 and a sound difference sensor 15 are provided in the installation box 5. According to the specifications of the sensor, a power supply of appropriate voltage is connected to the power pin of the sensor, the ultrasonic sensor 14 is connected to the transmitting and receiving signal lines to the data acquisition system or processing unit, and the acoustic difference sensor 15 is connected to the signal output pin to the data acquisition system. At the same time, it is ensured that all sensors and system components share a common ground line to ensure electrical stability; by setting the ultrasonic sensor 14 and the acoustic difference sensor 15, the density and temperature of the urea solution mixed in the pipeline mixer 9 can be measured in real time, providing real-time data, which helps to dynamically adjust the operation of the mixer, ensure the stability and accuracy of the mixing process, and thus obtain the concentration of the urea solution inside the pipeline mixer 9, so that the operation can be repeated continuously until the required urea concentrate is obtained, reducing human operation errors and improving the reliability and consistency of the measurement results.

[0021] Reference Figure 4 A handle 13 is fixedly installed on one side of the installation box 5, and the installation box 5 can be opened.

[0022] Reference Figure 2 and Figure 4 The bottom ends of the first pipe 6 and the second pipe 7 are both provided with electric regulating valves 4, which can regulate the ultrapure water pump 2 and the urea pump 3.

[0023] Reference Figure 4-5 An electromagnetic flowmeter 12 is provided at the top of the first pipe 6 near the electric regulating valve 4 to monitor the flow of the urea melt transported by the urea pump 3 .

[0024] Reference Figure 3-4 A vortex flowmeter 8 is provided on the top of the second pipeline 7 near the electric regulating valve 4 to monitor the flow rate of ultrapure water transported by the ultrapure water pump 2.

[0025] The implementation principle of the concentrated solution blending device based on the urea concentration sensor in the embodiment of the present application is as follows: when in use, ultrapure water can be delivered into the pipeline mixer 9 through the ultrapure water pump 2 and the second pipeline 7, and the urea melt can be delivered into the pipeline mixer 9 through the urea pump 3. The flow of the water pump is detected by the vortex flowmeter 8, and the flow of the urea melt is detected by the electromagnetic flowmeter 12. The staff can adjust the flow of the ultrapure water pump 2 and the urea pump 3 by controlling the two electric regulating valves 4 to control the delivery of ultrapure water and urea melt into the pipeline mixer 9 to mix them. Then, by turning on the ultrasonic sensor 14 and the sound difference sensor 15, the ultrasonic sensor 14 mainly measures the density of the medium by the propagation speed of the sound wave in the medium, and the sound difference sensor 15 detects the density and temperature by measuring the propagation time of the sound in different media or the change of the audio frequency, thereby measuring the density and temperature inside the pipeline mixer 9, and then obtaining the concentration of the urea solution. Subsequently, the operation is repeated continuously to control the mixing of the urea stock solution and the ultrapure water, and continuously perform detection to finally obtain the required concentration.
