The threaded plate will rotate deeply along the inside of the pneumatic threaded tube, forcing the internal air pressure of the pneumatic threaded tube to increase. The high-pressure gas pushes the pressure plate to slide toward the center of the clamping frame, and drives the pushing bar and the pressing and rotating plate to contact the grinding material.

Through the application of the above components, while realizing the detection, the equipment can quickly separate samples containing heavy metals, thereby improving the resolution efficiency of the equipment.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention changes the traditional method of grinding raw materials with a stirring rod. The raw materials to be ground are clamped by a grinding clamping mechanism, and the power supply of the power motor is turned on. As the air pressure inside the pneumatic threaded tube reaches the limit, the high-pressure gas will push the pressurized slide plate to move toward one end of the threaded plate, forcing the gas inside the pneumatic groove to enter the restricted air box through the restricted port, and the gas inside the restricted air box pushes the oblique slide plate to move outward, so that the outer wall of the oblique slide plate contacts the thread groove inside the pneumatic threaded tube, wherein the inclination angle of the restricted oblique slide plate is opposite to the thread of the thread plate. If the thread plate continues to move forward, the thread plate will increase the resistance of the thread plate. At this time, the force of the thread plate's own rotation will drive the pneumatic threaded tube to rotate. At this time, the push spring will generate an outward thrust, forcing the two pieces of raw materials to contact each other, and under the rotation of the rotating gear, the raw materials at both ends will rotate in different directions. Through the application of the above-mentioned components, it is possible to avoid metal chips from being mixed into the equipment due to damage to the metal grinding component, thereby affecting the accuracy of raw material detection.

[0016] (2) In view of the fact that various types of non-metallic mineral products have different shapes, the present invention provides a grinding clamping mechanism inside the equipment. Before the equipment is used, the raw materials to be tested are placed inside the clamping frame and the power of the power motor is turned on. The power motor transmits the power to the rotating gear through the driving gear and the transmission gear. The rotating gear drives the threaded plate to rotate through the square telescopic rod. At this time, the pneumatic threaded tube cannot rotate quickly due to the restriction of the external resistance wheel. Moreover, the threaded plate will rotate deeply along the inside of the pneumatic threaded tube, forcing the air pressure inside the pneumatic threaded tube to increase. The high-pressure gas pushes the pressure plate to slide toward the center of the clamping frame and drives the push bar and the pressing and rotating plate to contact the grinding raw materials. As the internal air pressure increases, the force of the pressure plate's extension increases, and the pressing and rotating plate will completely fit the outer wall of the irregular raw materials, so as to achieve full-range clamping of the bottom of the grinding raw materials, so that the equipment can use various types of raw materials of irregular volumes, and avoid the equipment's grinding effect being affected by the irregular shape of the raw materials during the grinding process.

[0017] (3) The present invention is provided with an X-ray fluorescence spectrometer inside the device. After the device completes grinding, the rotating force of the pneumatic threaded tube is utilized to drive the rotating column to rotate through the driving belt, and the rotating column drives the transmission belt to collect the powder generated by the top grinding, and transmits it to the detection area of ​​the X-ray fluorescence spectrometer through rotation, so as to realize the detection of heavy metals in the powder. When the X-ray fluorescence spectrometer detects that the powder contains heavy metals, an electrical signal is released to cause the fixed rod to contract inward, forcing the pressure plate to contact the outer wall of the friction plate. At this time, the pressure plate rotates and tightens the pulling belt. The pulling belt drives the pulling block to slide downward, and the downward movement of the pulling block squeezes the rotating baffle rod to rotate inward. The powder in the internal transportation state is blocked by the rotating baffle rod and discharged from the slide slot. Through the application of the above components, while realizing the detection, the device can quickly separate samples containing heavy metals, thereby improving the resolution efficiency of the device.

[0018] (4) The present invention utilizes the force generated by the rotation of the transmission belt. A cleaning rod and a cleaning knife are arranged inside the device. After the X-ray fluorescence spectrometer detects that the powder contains heavy metals, the cleaning knife will perform secondary cleaning on the transmission belt as the baffle rod is rotated to remove most of the metal-containing powder, so as to prevent the heavy metal-containing raw materials from sticking to the outer wall of the transmission belt and affecting the detection accuracy of subsequent raw materials. In addition, after the metal-containing part is collected, the X-ray fluorescence spectrometer loses the electrical signal, the electric telescopic rod extends, and the dispersion spring will release the accumulated power, releasing the collected pulling belt, and the spring inside the rotating baffle rod will simultaneously release the power to reset the rotating baffle rod and the pulling block.

The outer wall of the driving gear 106 is meshed with the outer wall of the driving gear 106, and the outer wall of the transmission gear 107 is meshed with the outer wall of the rotating gear 202.

[0037] For example 2, please refer to Figure 4 - Figure 8 The present invention is a heavy metal detection device for non-metallic mineral products. On the basis of Example 1, the grinding clamping mechanism 2 also includes a pushing spring 204 sleeved on the outer wall of the square telescopic rod 203, a sliding frame 205 is slidably connected to the inner wall of the sliding groove 110, and a plurality of resistance wheels 206 are rotatably connected to the inner wall of the sliding frame 205. The end of the square telescopic rod 203 away from the rotating gear 202 is fixedly connected to a threaded plate 207, and a side wall of the threaded plate 207 is provided with an air pressure groove 208.

[0038] The grinding clamping mechanism 2 also includes a pressure-bearing slide plate 209 slidably connected to the inner wall of the air pressure groove 208, a pressure threaded tube 210 is rotatably connected to the inner wall of the resistance wheel 206, a clamping frame 211 is fixedly connected to the inner wall of the pressure threaded tube 210, a plurality of limiting openings 212 are opened on the inner wall of the threaded plate 207, a limiting air box 213 is fixedly connected to the inner wall of the plurality of limiting openings 212, and an oblique slide plate 214 is slidably connected to the inner wall of the through hole on the limiting air box 213, thereby changing the traditional method of grinding raw materials with a stirring rod, clamping the raw materials to be ground by the grinding clamping mechanism 2, and connecting the power supply of the power motor 105, as the air pressure inside the pressure threaded tube 210 reaches the limit, the high-pressure gas will push the pressure-bearing slide plate 209 to move toward one end of the threaded plate 207, forcing the gas inside the air pressure groove 208 to pass through the limiting opening 212 enters the interior of the limiting air box 213, and the gas inside the limiting air box 213 pushes the inclined slide 214 to move outward, so that the outer wall of the inclined slide 214 contacts the internal thread groove of the pneumatic threaded tube 210, wherein the inclination angle of the limited oblique slide 214 is opposite to the thread of the threaded plate 207. If the threaded plate 207 continues to move forward, the threaded plate 207 will increase the resistance of the threaded plate 207. At this time, the force of the threaded plate 207's own rotation will drive the pneumatic threaded tube 210 to rotate. At this time, the push spring 204 will generate an outward thrust, forcing the two pieces of raw materials to contact each other, and under the rotation of the rotating gear 202, the raw materials at both ends will rotate in different directions. Through the application of the above-mentioned components, it is possible to prevent metal chips from being mixed into the equipment due to damage to the metal grinding component, thereby affecting the accuracy of raw material detection.

[0039] The grinding clamping mechanism 2 also includes a plurality of clamping grooves 215 provided on the outer wall of the clamping frame 211, the inner walls of the plurality of clamping grooves 215 are fixedly connected with slide rails 216, the inner walls of the slide rails 216 are slidably connected with pressure plates 217, the inner walls of the pressure plates 217 are slidably connected with a plurality of push bars 218, the top of the push bar 218 is fixedly connected with a return spring 219, the bottom of the push bar 218 is rotatably connected with a pressing rotating plate 220. In view of the different appearances of various non-metallic mineral products, a grinding clamping mechanism 2 is provided inside the equipment. Before the equipment is used, the raw materials to be tested are placed inside the clamping frame 211, and the power supply of the power motor 105 is turned on. The power motor 105 transmits the raw materials to the rotating gear 202 through the driving gear 106 and the transmission gear 107. The rotating gear The wheel 202 drives the threaded plate 207 to rotate through the square telescopic rod 203, while the pneumatic threaded tube 210 is restricted by the external resistance wheel 206 and cannot rotate quickly. In addition, the threaded plate 207 will rotate deeply along the inside of the pneumatic threaded tube 210, forcing the internal air pressure of the pneumatic threaded tube 210 to increase. The high-pressure gas pushes the pressure plate 217 to slide toward the center of the clamping frame 211, and drives the pushing bar 218 and the pressing and rotating plate 220 to contact the grinding material. As the internal air pressure increases, the extension force of the pressure plate 217 increases, and the pressing and rotating plate 220 will completely fit the outer wall of the irregular raw material, so as to achieve full-range clamping of the bottom of the grinding raw material, so that the equipment can use various types of raw materials of irregular volume, avoiding the irregularity of the raw material shape affecting the grinding effect of the equipment during the grinding process.

[0040] The detection mechanism 3 also includes a telescopic rod 305 fixedly connected to the outer wall of the rotating column 301, and the end of the telescopic rod 305 away from the rotating column 301 is fixedly connected to a rotating disk 306, and a driving belt 307 is sleeved on the outer wall of the rotating disk 306. The end of the driving belt 307 away from the rotating disk 306 is rotatably connected to the outer wall of the pneumatic threaded tube 210, and an X-ray fluorescence spectrometer 308 is fixedly connected to the outer wall of the fixed base plate 103. Using the force generated by the rotation of the transmission belt 302, a cleaning rod 303 and a cleaning knife 304 are arranged inside the device. After the X-ray fluorescence spectrometer 308 detects that the powder contains heavy metals, as the rotating baffle 315 removes most of the metal-containing powder, the cleaning knife 304 will perform a secondary cleaning on the transmission belt 302 to prevent the heavy metal-containing raw materials from sticking to the outer wall of the transmission belt 302 and affecting the subsequent detection accuracy of the raw materials.

[0041] The detection mechanism 3 also includes an electric telescopic rod 309 fixedly connected to the side wall of the X-ray fluorescence spectrometer 308, and the end of the electric telescopic rod 309 away from the X-ray fluorescence spectrometer 308 is fixedly connected to a fixed rod 310, and the end of the fixed rod 310 away from the electric telescopic rod 309 is rotatably connected to a pressure plate 311, and a dispersion spring 312 is fixedly connected to the inner wall of the pressure plate 311, and a pulling belt 313 is fixedly connected to the outer wall of the pressure plate 311. A friction plate 314 is fixedly connected to the outer wall of the rotating column 301, a rotating stopper 315 is rotatably connected to the inner wall of the slide groove 111, and a pulling block 316 is slidably connected to the inner wall of the slide groove 111. The end of the pulling belt 313 away from the friction plate 314 is fixedly connected to the outer wall of the pulling block 316, and an X-ray fluorescence spectrometer 308 is arranged inside the device. After the equipment completes grinding, the air pressure threaded tube 210 is rotated by the force of the air pressure threaded tube 210. The driving belt 307 drives the rotating column 301 to rotate, and the rotating column 301 drives the transmission belt 302 to collect the powder generated by the top grinding, and transmits it to the detection area of ​​the X-ray fluorescence spectrometer 308 through rotation, so as to detect the heavy metals in the powder. When the X-ray fluorescence spectrometer 308 detects that the powder contains heavy metals, an electrical signal is released to make the fixed rod 310 shrink inward, forcing the pressure plate 311 to contact the outer wall of the friction plate 314. At this time, the pressure plate 311 rotates and tightens the pulling belt 313. The pulling belt 313 drives the pulling block 316 to slide downward, and the downward movement of the pulling block 316 squeezes the rotating baffle 315 to rotate inward. The powder in the internal transportation state is blocked by the rotating baffle 315 and discharged from the slide 111. Through the application of the above components, while realizing the detection, the device can quickly separate the samples containing heavy metals, thereby improving the resolution efficiency of the device.

[0042] A specific application of this embodiment is: before the equipment is used, the raw materials to be tested are placed inside the clamping frame 211, and the power of the power motor 105 is turned on. The power motor 105 transmits the power to the rotating gear 202 through the driving gear 106 and the transmission gear 107. The rotating gear 202 drives the threaded plate 207 to rotate through the square telescopic rod 203. At this time, the pneumatic threaded tube 210 is restricted by the external resistance wheel 206 and cannot rotate quickly. Moreover, the threaded plate 207 will rotate deeply along the inside of the pneumatic threaded tube 210, forcing the air pressure inside the pneumatic threaded tube 210 to increase. The high-pressure gas pushes the pressure plate 217 to slide toward the center of the clamping frame 211, and drives the push bar 218 and the pressing rotating plate 220 to contact the grinding raw materials. As the internal air pressure increases, the force of the outer extension of the pressure plate 217 increases, and the pressing rotating plate 220 will completely fit the outer wall of the irregular raw material, so as to achieve full-range clamping of the bottom of the grinding raw material, so that the equipment can use various types of irregular-sized raw materials, and avoid the equipment from affecting the grinding effect of the equipment due to the irregular shape of the raw materials during the grinding process. As the air pressure inside the air pressure threaded tube 210 reaches the limit, the high-pressure gas will push the pressure slide plate 209 to move toward one end of the threaded plate 207, forcing the internal gas of the air pressure groove 208 to enter the interior of the limiting air box 213 through the limiting port 212, and the internal gas of the limiting air box 213 pushes the oblique slide plate 214 to move outward, so that the outer wall of the oblique slide plate 214 contacts the internal thread groove of the air pressure threaded tube 210, wherein the pressure The inclination angle of the limiting inclined slide plate 214 is opposite to the thread of the thread plate 207. If the thread plate 207 continues to move forward, the thread plate 207 will increase the resistance of the thread plate 207. At this time, the force of the thread plate 207's own rotation will drive the pneumatic threaded tube 210 to rotate. At this time, the push spring 204 will generate an outward thrust, forcing the two pieces of raw materials to contact each other, and under the rotation of the rotating gear 202, the raw materials at both ends will rotate in different directions. An X-ray fluorescence spectrometer 308 is arranged inside the equipment. After the equipment completes grinding, the pneumatic threaded tube 210 uses the force of its rotation to drive the rotating column 301 to rotate through the driving belt 307, and the rotating column 301 drives the transmission belt 302 to collect the top grinding product. The raw powder is transmitted to the detection area of ​​the X-ray fluorescence spectrometer 308 through rotation to realize the detection of heavy metals in the powder. When the X-ray fluorescence spectrometer 308 detects that the powder contains heavy metals, an electrical signal is released to make the fixed rod 310 contract inward, forcing the pressure plate 311 to contact the outer wall of the friction plate 314. At this time, the pressure plate 311 rotates and tightens the pulling belt 313. The pulling belt 313 drives the pulling block 316 to slide downward, and the downward movement of the pulling block 316 squeezes the rotating baffle 315 to rotate inward. The powder in the internal transportation state is blocked by the rotating baffle 315 and discharged from the slide 111. The force generated by the rotation of the transmission belt 302 is used to set a cleaning rod 303 and a cleaning knife 304 inside the equipment.After the X-ray fluorescence spectrometer 308 detects that the powder contains heavy metals, the cleaning knife 304 will perform secondary cleaning on the transmission belt 302 as the rotating baffle 315 removes most of the metal-containing powder to prevent the heavy metal-containing raw materials from sticking to the outer wall of the transmission belt 302 and affecting the detection accuracy of subsequent raw materials. In addition, after the metal-containing part is collected, the X-ray fluorescence spectrometer 308 loses the electrical signal, the electric telescopic rod 309 extends, and the dispersion spring 312 releases the accumulated power, releasing the collected pulling belt 313, and the spring inside the rotating baffle 315 simultaneously releases the power to reset the rotating baffle 315 and the pulling block 316.
