[0016] Through the cooperation of structures such as the elastic air bag, the bottom control nozzle and the high-pressure input pipe, when the flour flow rate in the buffer hopper is small, the elastic air bag can be controlled to expand, so as to reduce the horizontal cross-sectional area at the height where the infrared detection probe is located, making the flour flowing through the infrared detection probe more concentrated at small flow rates and improving the detection stability; when the flour flow rate in the buffer hopper is large, the elastic air bag is automatically controlled to contract to reduce the obstruction caused by the elastic air bag and ensure the flour flowability under large flow rates.

[0031] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a flour conventional index detection device with a real-time detection function, such as Figure 1As shown in the figure, it includes a buffer hopper 1 and a distribution conveying pipe 2 connected to the bottom of the buffer hopper 1. An infrared detection probe 3 is embedded on the side wall surface of the buffer hopper 1. The infrared detection probe 3 is used to detect the conventional indicators of the flour in the buffer hopper 1. The infrared detection probe 3 uses a MYRG infrared on-line analysis sensor. Its working principle is that when the flour flows through the probe, it is irradiated by a near-infrared light source, and the reflected light is absorbed through a lens and transmitted to a spectrometer through an optical fiber within a few milliseconds to realize the detection of flour ash content, protein content, moisture content, etc.; its working stability is affected by the aggregation degree when the flour flows through the probe. If the flour is too dispersed, it will affect the light reflection intensity and lead to a decrease in detection accuracy.

[0032] An upper suspension 4 and a lower suspension 5 are fixedly arranged inside the buffer hopper 1. The upper suspension 4 is located above the lower suspension 5. An elastic air bag 6 is arranged between the upper suspension 4 and the lower suspension 5. The elastic air bag 6 is made of rubber and has elasticity.

[0035] An oscillation disk body 901 is provided in the intermediate control bin 9. A corrugated sealing curtain 902 is provided at the edge position of the oscillation disk body 901.

[0036] A return spring 905 is provided on one side of the oscillation disk body 901. The return spring 905 exerts an elastic force on the oscillation disk body 901, so that the oscillation disk body 901 has a tendency to move away from the side where the positioning central axis 903 is located. A breathing air hole 906 is penetrated and opened in the central axis fitting sleeve 904.

[0038] A temperature-sensitive gas inner cavity 910 is opened in the oscillation disk body 901 and the positioning central axis 903. A connecting bridge column 911 is fixedly provided on the surface of the oscillation disk body 901. A regulating variable volume cavity 912 is fixedly provided at the end of the connecting bridge column 911. A fixed wall tube 913 is fixedly provided on the inner surface of the regulating variable volume cavity 912.

[0039] A variable volume cavity path 914 and a wall tube cavity path 915 are opened inside the connecting bridge column 911. One end of the variable volume cavity path 914 is communicated with the inner cavity of the intermediate control bin 9, and the other end of the variable volume cavity path 914 is communicated with the inner cavity of the regulating variable volume cavity 912. One end of the wall tube cavity path 915 is communicated with the temperature-sensitive gas inner cavity 910, and the other end of the wall tube cavity path 915 is communicated with the fixed wall tube 913.

[0040] A variable volume plug disk 916 is provided inside the regulating variable volume cavity 912. The variable volume plug disk 916 is in sealing contact with the inner wall surface of the regulating variable volume cavity 912. A balance plug shaft 917 is fixedly provided on the variable volume plug disk 916. A wall tube piston 918 is fixedly provided at the end of the balance plug shaft 917. The wall tube piston 918 is located inside the fixed wall tube 913 and is in sealing contact with the inner wall surface of the fixed wall tube 913.

[0041] An electromagnetic control valve 801 and a pressure sensor 802 are provided on the high-pressure input pipe 8. The electromagnetic control valve 801 is used to control the on-off of the high-pressure input pipe 8, and the pressure sensor 802 is used to detect the pressure in the high-pressure input pipe 8 and the elastic air bag 6.

[0042] When the device for detecting the conventional indexes of flour of the present invention is in use, the high-pressure input pipe 8 is communicated with a positive-pressure air source such as an external high-pressure air pump, the electromagnetic control valve 801 is in a normally closed state, the buffer hopper 1 is connected to the output end of equipment such as a flour mill, and flour is input into the buffer hopper 1 and distributed into the distribution and conveying pipe 2 through the buffer hopper 1.

[0043] The flour flows through the inside of the buffer hopper 1, and the conventional indexes are detected by the infrared detection probe 3; when the flour output flow rate of upstream equipment such as a flour mill is small, the electromagnetic control valve 801 is controlled to open, so that the high-pressure gas in the high-pressure input pipe 8 enters the elastic air bag 6 through the intermediate control bin 9 and the air inlet channel 10, causing the elastic air bag 6 to expand and enlarge. At this time, the position height of the infrared detection probe 3, in the horizontal section, due to the expansion and enlargement of the elastic air bag 6 occupying most of the horizontal section space, the passing section of the flour is reduced, and thus the flour flowing through the infrared detection probe 3 with a small flow rate is more concentrated, improving the detection stability. The expansion volume of the elastic air bag 6 is inversely proportional to the flour flow rate. The volume control of the elastic air bag 6 is detected by the air pressure sensor 802. Since the high-pressure input pipe 8 is communicated with the elastic air bag 6, the air pressure sensor 802 can detect the pressure intensity in the elastic air bag 6. When the pressure in the elastic air bag 6 reaches the set value, it means that the volume of the elastic air bag 6 has expanded in place, and the electromagnetic control valve 801 is controlled to close to maintain the expansion of the elastic air bag 6.

[0044] When the flour flow rate increases, as Figure 5 shown, the synchronous rotating shaft 705 is controlled to rotate by the rotation control module 706, so that the sealing rotating block 703 rotates. At this time, the elastic air bag 6 is communicated with the output nozzle 701 through the communication air hole 704, and the gas in the elastic air bag 6 is ejected through the output nozzle 701, causing the elastic air bag 6 to contract and return to a reduced volume, so as to reduce the obstruction caused by the elastic air bag 6 and ensure the flour fluidity under a large flow rate; at the same time, the output nozzle 701 jets downward to jet air at the bottom of the buffer hopper 1 to accelerate the falling of the flour and remove the accumulation at the bottom.

[0045] Under the condition that the elastic air bag 6 is in a certain degree of expansion working condition, as Figure 6 and Figure 7 shown, the cam motor 908 drives the driving cam 907 to rotate, intermittently extruding the oscillating disc body 901, and cooperating with the elastic reset of the reset spring 905, so that the oscillating disc body 901 is in an axial high-frequency reciprocating oscillation state. The oscillating disc body 901 and the intermediate control bin 9 cooperate to form an extrusion oscillation of the gas, causing the volume of the elastic air bag 6 to expand and contract at a high frequency. At this time, the elastic air bag 6 shows an oscillating state, which can improve the smoothness of the flour falling around the elastic air bag 6.

[0046] Due to the high-frequency oscillation and extrusion of the oscillating disk body 901, continuous work is done on the gases in the intermediate control chamber 9 and the elastic air bag 6, which will cause the above-mentioned gases to heat up and increase in volume, thereby affecting the volume of the elastic air bag 6. As a result, the volume of the elastic air bag 6 gradually increases during long-term operation, affecting the control accuracy of the elastic air bag 6. Similarly, during the high-frequency oscillation of the oscillating disk body 901, the friction between the positioning central shaft 903 and the central shaft mating sleeve 904, and the extrusion friction between the oscillating disk body 901 and the driving cam 907 will both cause the temperatures of the oscillating disk body 901 and the positioning central shaft 903 to gradually increase with the working time, so that the temperature of the gas in the temperature-sensitive gas inner cavity 910 gradually increases with the working time.

[0047] When the positive-pressure gas is input into the elastic air bag 6 through the high-pressure input pipe 8 to make the elastic air bag 6 expand, the above positive-pressure gas acts on the control variable chamber 912 through the intermediate control chamber 9 and the variable volume chamber path 914, pushing the variable volume plug disk 916 to shift axially. At this time, the balance plug shaft 917 will be subjected to a pulling force, making the fixed wall pipe 913 and the temperature-sensitive gas inner cavity 910 in a negative pressure state, and the forces of the two are balanced. As the above working time gradually increases, the temperature of the gas in the temperature-sensitive gas inner cavity 910 increases, and the volume of the gas in the temperature-sensitive gas inner cavity 910 expands, which will cause the variable volume plug disk 916 to shift axially to the side away from the balance plug shaft 917, increasing the accommodation space of the control variable chamber 912, so that the control variable chamber 912 accommodates the gas in the elastic air bag 6 through the variable volume chamber path 914, weakening the volume change caused by the temperature rise and expansion of the gas in the elastic air bag 6, improving the dimensional stability of the elastic air bag 6, and ensuring the control accuracy.
