DETAILED DESCRIPTION

[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. EMBODIMENT

[0022] A conveying belt brewing raw material moisture on-line detection device, as shown in Figs. 1 to 5 the drawing, comprises a conveying belt 1, a fixed frame 2 and a detector 3. The detector 3 comprises a control box 301, a display terminal 302, a high-frequency capacitance moisture detection probe 303 and a height self-adaptive support 304. The display terminal 302 is arranged on the shell of the control box 301. The high-frequency capacitance moisture detection probe 303 is electrically connected with the display terminal 302 through a data line. The fixed frame 2 is a 7-shaped support body. The vertical arm of the 7-shaped support body is arranged on one side of the conveying belt 1. The horizontal arm of the 7-shaped support body is arranged across the conveying belt 1. The control box 301 is arranged on the side of the vertical arm of the 7-shaped support body away from the conveying belt 1. One end of the height self-adaptive support 304 is rotatably arranged on the horizontal arm of the 7-shaped support body. The other end of the height self-adaptive support 304 is arranged with the high-frequency capacitance moisture detection probe 303. The bottom of the high-frequency capacitance moisture detection probe 303 is in sliding contact with the brewing raw material on the conveying belt 1.

[0023] The working principle of the high-frequency capacitance method is as follows: based on the high-frequency capacitance principle, the high-frequency electric field acts on the raw material to measure the change of the dielectric constant, and then the moisture content is calculated. The higher the moisture content is, the larger the dielectric constant is. Accordingly, the moisture percentage is calculated.

[0024] The high-frequency capacitance moisture detection probe 303 is used to collect the dielectric constant change value of the brewing raw material in real time, display the value on the display terminal 302, and transmit the measurement data to the upper computer software. According to the change of the dielectric constant, the upper computer software gives the water content corresponding to the dielectric constant value.

[0025] Because the conveying belt 1 used by the brewing raw material is food-grade stainless steel material, and the thickness of the raw material reaches more than 10 cm, the microwave emission probe signal is difficult to penetrate, and the near-infrared spectrum detection system is relatively high in cost, therefore, the high-frequency capacitance method for measuring the moisture of the conveying belt brewing raw material has higher performance price ratio.

[0026] The high-frequency capacitance moisture detection probe 303 comprises a boat-shaped slide plate 3031, a detection head 3032, and a slide plate vertical fixing piece 3033. The bottom of the boat-shaped slide plate 3031 is provided with a circular opening, and the detection head 3032 is installed at the circular opening. The detection surface of the detection head 3032 coincides with the lower plane of the boat-shaped slide plate 3031. The slide plate vertical fixing piece 3033 is fixedly arranged on the top of the boat-shaped slide plate 3031 through a cross beam 3034.

[0027] The boat-shaped slide plate 3031 is designed as a boat-shaped arc surface on the side in the direction of the incoming material of the conveying belt 1. When the raw material passes below the boat-shaped slide plate 3031, the surface of the raw material is pressed into a plane by the weight of the boat-shaped slide plate 3031, so as to ensure good contact. When the surface of the raw material is uneven, the raw material is pressed toward the lower side of the boat-shaped slide plate 3031 through the arc surface on the front side of the boat-shaped slide plate 3031, and moves up and down with the raw material through the height self-adaptive support 304, so as to adapt to the moisture measurement of raw materials with different thicknesses.

[0028] The detection head 3032 comprises a flange base 30321, a flange shell 30322, a ceramic protective sheet 30323, a high-frequency capacitance positive electrode 30324, and a negative electrode 30325. The flange base 30321 is provided with a circular groove, and the flange shell 30322 is correspondingly provided with a circular protrusion. The circular groove and the circular protrusion are used in cooperation to ensure the sealing connection between the flange base 30321 and the flange shell 30322. The ceramic protective sheet 30323 is installed on the side of the flange base 30321 and directly contacts the brewing raw material with the bottom surface thereof as a detection surface. The flange base 30321 is connected with the flange shell through a flange fixing hole. The high-frequency capacitance positive electrode 30324 is arranged on the top surface of the ceramic protective sheet 30323. The negative electrode 30325 is in a circular ring structure and is arranged on the top surface of the ceramic protective sheet 30323 around the high-frequency capacitance positive electrode 30324 with the high-frequency capacitance positive electrode 30324 as the center. The flange shell 30322 is provided with a data interface 305. The high-frequency capacitance positive electrode 30324 and the negative electrode 30325 are connected with the data interface 305 through a data line.

[0029] Through the high-frequency capacitance electrode, an annular high-frequency electric field penetrating the ceramic protective sheet 30323 and the raw material is formed. The raw material serves as the electric field medium. When the moisture content of the raw material changes, the dielectric constant of the medium also changes, so that the capacitance value changes. Through the high-frequency capacitance resonance principle, the capacitance value between the positive electrode and the negative electrode is measured, and then the moisture content is calculated and transmitted to the display terminal 302 through the data interface 305.

[0030] The height self-adapting support 304 comprises two parallel support arms 3041, one end of the two support arms 3041 is rotatably arranged on the 7-shaped support body horizontal arm through the support vertical fixing member 3042 along the conveying direction of the conveying belt 1, and the other end of the two support arms 3041 is rotatably connected with the slide plate vertical fixing member 3033.

[0031] The two ends of the two support arms 3041 are rotatably connected with the support vertical fixing member 3042 and the slide plate vertical fixing member 3033 to form a movable parallelogram structure, and the two support arms 3041 take the support vertical fixing member 3042 as a parallelogram fixed side, and the two support arms 3041 and the slide plate vertical fixing member 3033 as movable sides of the parallelogram, so as to form a movable parallelogram structure to realize the effect of self-adapting ups and downs along with the height of the conveying belt raw material.

[0032] The 7-shaped support body horizontal arm is provided with an L-shaped support 4, the L-shaped support 4 is fixedly connected with the 7-shaped support body horizontal arm at the side of the vertical plate away from the horizontal plate, and the support vertical fixing member 3042 is installed at the side of the vertical plate of the L-shaped support 4 close to the horizontal plate.

[0033] The control box 301 comprises a box body 3011 and a box cover 3012, the box body 3011 is provided with a power interface 5, a moisture detector interface 6 and an upper computer interface 7, the box cover 3012 is provided with a power switch 8, a box lock 9 and a display terminal 302, the display terminal 302 is connected with an external power supply through the power interface 5, connected with the high-frequency capacitor moisture detection probe 303 in data through the moisture detector interface 6, connected with an upper computer in data through the upper computer interface 7, and the power switch 8 is used for controlling the display terminal 302 to start, stop and shut down.
