[0014] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0015] like Figure 1-2 As shown, the utility model provides an automatic detection system for a liquid melting accelerator, including a pH value measurement system, a density meter sensor 3 and a moisture detector 2, wherein the moisture detector 2 is arranged on a discharge pipe 11 of a compounding kettle 1;

[0016] The moisture detector 2 is mainly composed of a microwave oscillator and a microwave attenuator. The microwave transmitting source of the lower arm of the C-shaped frame of the microwave moisture meter located below the conveyor belt emits high-frequency electromagnetic waves. The microwaves pass through the belt and the melting accelerator and are received by the microwave receiver located on the upper arm of the C-shaped frame at the upper end of the belt. When the microwaves pass through the liquid melting accelerator, attenuation and phase change occur. The dielectric constant and loss tangent value are mainly determined by its moisture content. According to the attenuation of microwave power and the change of phase shift, the moisture content in the liquid melting accelerator can be calculated.

[0017] The density meter sensor 3 is arranged on the side of the compounding kettle 1 and is inserted into the tank body horizontally. The density meter sensor 3 is a tuning fork density meter;

[0018] The density meter sensor 3 works based on the principle of component vibration. The component part is a tuning fork part immersed in a liquid melting promoter. The tuning fork part senses vibrations through an internal piezoelectric device fixed at one end of the bottom of the fork body. The oscillation frequency is detected by a secondary piezoelectric device fixed at the other end of the fork body, and then the signal is amplified by the circuit on the top. The density of the liquid melting promoter is closely related to the vibration frequency of the measured liquid during flow. When the density of the measured liquid changes, the vibration frequency of the liquid during flow also changes accordingly. The density of the measured liquid can be accurately displayed on the instrument through calculations using specific equations. During the density detection process, the insertion density meter can automatically compensate for the influence of temperature on the density of the measured medium, thereby avoiding the influence of pressure on the test results. Its density detection range is 0.5-2.5g / cc (500–2500kg / m3), and the detection accuracy can reach

[0019] ±0.002g / cc(±2kg / m3).

[0020] The pH value measurement system is arranged on the tank body of the compounding kettle 1, and the pH value measurement system includes a pH meter 4 and a pH electrode 5. The pH meter 4 is electrically connected to the pH electrode 5, and the pH electrode 5 is arranged on the side of the compounding kettle 1 and obliquely inserted into the tank body; the pH meter 4 is composed of signal measurement, calculation, display, network communication and panel instructions, etc., and the transmission impedance of pH and temperature is transformed to convert pH into a low-resistance signal; NTC is converted into a voltage signal;

[0021] The meter is matched with the pH electrode 5 to detect the pH value of the liquid melting accelerator. The sensor is a battery composed of a pH glass electrode and a calomel reference electrode, which generates a potential difference related to the pH value of the solution. The potential difference is amplified by a preamplifier with high input impedance, and the thermistor sends a signal corresponding to the temperature value. After the two sets of signals are amplified, they are converted by A / D and displayed on the display screen in time after being calculated by a single-chip microprocessor through an I / O interface chip. The device can detect the pH value of various types of melting accelerators, and its detection range is 0.00-14.00pH, and the accuracy can reach ±0.05pH. The high-impedance preamplifier equipped with the industrial pH meter has the advantages of high input impedance, anti-noise, and strong anti-interference ability. The pH electrode can be taken out by plugging and unplugging at any time for calibration.

[0022] In addition, the moisture detector 2, density meter sensor 3 and pH meter 4 are electrically connected to the controller in the central control room through the remote module 6. The central control personnel can remotely view the various physical and chemical indicators of the melting promoter in the compound kettle 1 through the integrated automatic detection system data terminal.

[0023] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
