Description

Technical Field

[0001] The present invention relates to the technical field of calcium carbonate production, and in particular to a heavy calcium carbonate production sampling device. Background Art

[0002] Heavy calcium carbonate is a white powdery inorganic filler made from natural carbonate minerals such as calcite, marble, and limestone through processes such as crushing and grinding. During the production process, since heavy calcium carbonate is usually packaged and transported in the form of ton bags, in order to ensure the consistency and stability of product quality, it is necessary to sample the heavy calcium carbonate in the ton bags.

[0003] Existing devices have some drawbacks during use. For example, when sampling heavy calcium carbonate in ton bags, existing sampling devices can only sample the surface of the heavy calcium carbonate in the ton bags, and cannot sample heavy calcium carbonate at different depths in the ton bags. Due to the limitations of surface sampling, the test results obtained cannot truly reflect the quality and characteristics of the entire bag of products, which will lead to deviations in product quality assessment and thus affect subsequent production and use.

The top of the four upper connecting rods 306 is fixedly connected with a sleeve 307. The four upper connecting rods 306 are connected with the sampling tube 303 and the sleeve 307 to form a discharge trough 41 between the two adjacent upper connecting rods 306 and the sleeve 307 and the sampling tube 303 in the same group. The sampling assembly 3 includes a third motor 308 fixedly connected to the upper end surface of the sleeve 307. A rotating rod 309 is vertically provided on the inner side of the sampling tube 303. The bottom end of the rotating rod 309 is rotatably connected to the upper end surface of the insert block 305. The top of the rotating rod 309 vertically passes through the sleeve 307 and is rotatably connected to the sleeve 307. The top of the rotating rod 309 is fixedly connected to the output end of the third motor 308. The outer side of the rotating rod 309 is fixedly sleeved with a spiral auger blade 310. The spiral auger blade 310 is fixedly sleeved on the outer side of the rotating rod 309. The pitch of 10 gradually decreases from bottom to top, and the sampling assembly 3 includes a lower discharge plate 311 fixedly sleeved on the outer side of the top of the sampling tube 303, and an upper discharge plate 312 fixedly sleeved on the outer side of the sleeve 307. The upper discharge plate 312 and the lower discharge plate 311 are both tilted downward, and a discharge cavity 313 is formed between the upper discharge plate 312 and the lower discharge plate 311. Four arc-shaped inner placement grooves 314 are provided in an annular array on the lower end surface of the lower discharge plate 311, and arc-shaped inner card grooves 315 are provided on one side of the lower end surface of the lower discharge plate 311 close to the four arc-shaped inner placement grooves 314. The four arc-shaped inner card grooves 315 are respectively connected to the corresponding arc-shaped inner placement grooves 314, and four arc-shaped outer placement grooves 316 are provided in an annular array on the lower end surface of the upper discharge plate 312. The sides of the surface close to the four arc-shaped outer placement grooves 316 are each provided with an arc-shaped outer card slot 317, and the four arc-shaped outer card slots 317 are respectively connected to the corresponding arc-shaped outer placement grooves 316. Two transparent arc-shaped collecting boxes 318 are provided below the upper discharge plate 312 and the lower discharge plate 311, and the upper end faces of the two transparent arc-shaped collecting boxes 318 correspond to the positions of the same group of two arc-shaped inner placement grooves 314 and the same group of two arc-shaped outer placement grooves 316, and are respectively fixedly connected with two arc-shaped inner card blocks 319 and two arc-shaped outer card blocks 320. The four arc-shaped inner card blocks 319 and the four arc-shaped outer card blocks 320 are respectively used in conjunction with the corresponding arc-shaped inner card slots 315 and arc-shaped outer cards. During specific use, when the sampling component 3 is aligned with the sampling point of the ton bag by moving the component 2 horizontally,Start the first motor 14 to drive the lifting screw 13 to rotate. The rotation of the lifting screw 13 drives the lifting block 15 to descend along the lifting groove 12. The descent of the lifting block 15 drives the lateral moving component 2 and the sampling component 3 to descend until the sampling component 3 is inserted into the ton bag. When the sampling device is inserted into the ton bag and descends to the specified depth, turn off the first motor 14. The conical surface design of the lower end face of the plug block 305 helps the plug block 305 to be smoothly inserted into the ton bag. Start the third motor 308. The third motor 308 drives the rotating rod 309 to rotate, thereby driving the spiral auger blade 310 to rotate in the sampling tube 303. The rotation of the spiral auger blade 310 will remove the heavy carbon. Calcium carbonate is sucked into the sampling tube 303 from the feed trough 40 around the plug 305 and transported upward along the spiral auger blade 310. Since the pitch of the spiral auger blade 310 gradually decreases from bottom to top, this design enhances the upward conveying force of the heavy calcium carbonate, ensuring that the heavy calcium carbonate can be discharged smoothly. When the heavy calcium carbonate is transported to the top of the sampling tube 303, the heavy calcium carbonate enters the discharge cavity 313 between the upper discharge plate 312 and the lower discharge plate 311 through the discharge trough 41, and enters the two transparent arc-shaped collection boxes 318 through the discharge cavity 313. Since the two transparent arc-shaped collection boxes 318 are transparent, the operator can see the contents of the two transparent arc-shaped collection boxes 318. The sampling volume is as follows: when the sampling volume reaches the requirement, the third motor 308 is turned off to stop the rotation of the rotating rod 309 and the spiral auger blade 310, and then the first motor 14 is started. The first motor 14 drives the lifting screw 13 to rotate in the reverse direction. The rotation of the lifting screw 13 drives the lifting block 15 to rise along the lifting slot 12 until the horizontal moving component 2 and the sampling component 3 are raised to the initial position. When the horizontal moving component 2 and the sampling component 3 are raised to the initial position, the first motor 14 is turned off, and then the knocking component 7 is started and the third motor 308 is started to reversely drive the rotating rod 309 and the spiral auger blade 310 to rotate in the reverse direction to empty the heavy calcium carbonate in the sampling tube 303 and insert The conical surface designed on the upper end face of the block 305 ensures that the heavy calcium carbonate can be discharged smoothly and fall into the ton bag. When the heavy calcium carbonate in the sampling tube 303 is emptied, the third motor 308 and the knocking component 7 are turned off. Then, the two transparent curved collection boxes 318 are rotated along the sampling tube 303 as the axis until the curved inner clamping block 319 and the curved outer clamping block 320 on the two transparent curved collection boxes 318 slide along the corresponding curved inner clamping groove 315 and the curved outer clamping groove 317 respectively. When the curved inner clamping block 319 and the curved outer clamping block 320 slide to the corresponding curved inner placement groove 314 and the curved outer placement groove 316 respectively, the two transparent curved collection boxes 318 are removed.

[0023] As an implementation method in this embodiment, Figure 1 、 Figure 4 and Figure 10As shown, the knocking component 7 includes a mounting cavity 701 opened on one side of the lower end surface of the connecting seat 301, and a rotating shaft 702 is provided on the inner side of the mounting cavity 701. One end of the rotating shaft 702 is rotatably connected to the inner wall of one side of the mounting cavity 701, and the other end of the rotating shaft 702 transversely passes through the outer wall of one side of the connecting seat 301 and is rotatably connected to the outer wall of one side of the connecting seat 301. The outer wall of one side of the connecting seat 301 is fixedly connected to the position of the rotating shaft 702 corresponding to the fourth motor 703, and the end of the rotating shaft 702 close to the fourth motor 703 is fixedly connected to the output end of the fourth motor 703. The outer side of the rotating shaft 702 is fixedly sleeved with a deflected transmission wheel 704, and the deflected transmission wheel 704 is provided with a There is a transmission groove 705, and the knocking component 7 includes a mounting plate 706 fixedly connected to the position of the mounting cavity 701 on both sides of the lower end surface of the connecting seat 301, wherein a first limit block 707 is provided on the side of the mounting plate 706 away from the sampling tube 303, and a moving rod 708 is fixedly connected to the outer wall of the first limit block 707 close to the sampling tube 303. The end of the moving rod 708 close to the sampling tube 303 horizontally passes through the two mounting plates 706 and is slidably connected to the two mounting plates 706. The upper end surface of the moving rod 708 is fixedly connected to the position corresponding to the transmission groove 705, and the top of the connecting shaft 709 is rotatably sleeved with a spherical transmission block 7 10. The spherical transmission block 710 is used in conjunction with the transmission groove 705. The end of the moving rod 708 close to the sampling tube 303 is fixedly connected to the connecting plate 711. A knocking plate 712 is provided on the side of the connecting plate 711 close to the sampling tube 303. The knocking plate 712 is symmetrically fixedly connected to the outer wall of the side close to the connecting plate 711 with sliding rods 713. The ends of the two sliding rods 713 close to the connecting plate 711 horizontally penetrate the connecting plate 711 and are slidably connected to the connecting plate 711. The ends of the two connecting plates 711 away from the knocking plate 712 are fixedly connected to the second limit block 714. The outer sides of the two sliding rods 713 are both provided with springs 715. The two springs 715 are set Between the knocking plate 712 and the connecting plate 711, a rubber protective pad 716 is fixedly connected to the outer wall of the knocking plate 712 close to the sampling tube 303. During specific use, when the heavy calcium carbonate in the sampling tube 303 needs to be discharged, the fourth motor 703 is started, and the output end of the fourth motor 703 drives the rotating shaft 702 to drive the deflected transmission wheel 704 to rotate. The rotation of the deflected transmission wheel 704 causes the transmission groove 705 to drive the spherical transmission block 710 and the moving rod 708 to move back and forth through the connecting shaft 709, so that the knocking plate 712 knocks the sampling tube 303. During the knocking process, the vibration generated by the knocking can make the calcium carbonate attached to the sampling tube 303 The heavy calcium carbonate on the inner wall and the spiral auger blade 310 is loosened and falls off, further promoting the discharge of heavy calcium carbonate. When the knocking plate 712 contacts the sampling tube 303, the spring 715 can play a buffering role, reducing the damage caused by the impact force generated by the knocking to the sampling tube 303 and the material. At the same time, after the knocking is completed, the spring 715 can quickly reset the knocking plate 712.The rubber protective pad 716 has good elasticity and flexibility, which can further cushion the impact force during the knocking, preventing the knocking plate 712 from directly contacting the sampling tube 303 and effectively protecting the surface of the sampling tube 303 from damage. The first limit block 707 and the second limit block 714 respectively limit the range of motion of the movable rod 708 and the sliding rod 713, preventing the movable rod 708 and the sliding rod 713 from separating during movement, thus ensuring the matching accuracy and movement stability of the various components of the knocking assembly 7.

[0024] Working principle: By pushing the armrest 50, the entire sampling device can be easily moved to the ton bag position. The U-shaped base 10 ensures the stability of the device during movement. The four universal casters 60 enable the entire sampling device to move flexibly on the ground. When the entire sampling device moves to the ton bag position, the four universal casters 60 are locked to ensure the stability of the sampling device during the sampling process. At this time, the sampling component 3 is at the highest point, and the second motor 204 is started. The second motor 204 drives the lateral adjustment screw 203 to rotate. The rotation of the adjustment screw drives the lateral movement block 205 to move laterally along the lateral movement groove 202, so that the sampling component 3 is aligned with the sampling point of the ton bag. When the sampling component 3 is aligned with the sampling point of the ton bag, the second motor is turned off. The machine 204 is turned on and the first motor 14 is started. The first motor 14 drives the lifting screw 13 to rotate. The rotation of the lifting screw 13 drives the lifting block 15 to descend along the lifting groove 12. The descent of the lifting block 15 drives the lateral moving component 2 and the sampling component 3 to descend until the sampling component 3 is inserted into the inside of the big bag. When the sampling device is inserted into the inside of the big bag and descends to the specified depth, the first motor 14 is turned off. The conical surface design of the lower end face of the plug block 305 helps the plug block 305 to be smoothly inserted into the inside of the big bag. The third motor 308 is started and the third motor 308 drives the rotating rod 309 to rotate, thereby driving the spiral auger blade 310 to rotate in the sampling tube 303. The rotation of the spiral auger blade 310 removes the heavy calcium carbonate from the plug block 305. The feeding trough 40 around it sucks the sampling tube 303 and transports it upward along the spiral auger blade 310. Since the pitch of the spiral auger blade 310 gradually decreases from bottom to top, this design enhances the upward conveying force of the heavy calcium carbonate, ensuring that the heavy calcium carbonate can be discharged smoothly. When the heavy calcium carbonate is transported to the top of the sampling tube 303, the heavy calcium carbonate enters the discharge cavity 313 between the upper discharge plate 312 and the lower discharge plate 311 through the discharge trough 41, and enters the two transparent arc-shaped collection boxes 318 through the discharge cavity 313. Since the two transparent arc-shaped collection boxes 318 are transparent, the operator can see the sampling amount in the two transparent arc-shaped collection boxes 318. When the sampling amount reaches the requirement, the third motor 308 is turned off to stop the rotating rod 3 09 and the spiral auger blade 310 rotate, and then start the first motor 14, the first motor 14 reverse drives the lifting screw 13 to rotate, the rotation of the lifting screw 13 drives the lifting block 15 to rise along the lifting slot 12 until the lateral moving component 2 and the sampling component 3 are raised to the initial position, when the lateral moving component 2 and the sampling component 3 are raised to the initial position, the first motor 14 is turned off, and then the third motor 308 is started to reversely drive the rotating rod 309-type spiral auger blade 310 to rotate in the opposite direction, emptying the heavy calcium carbonate in the sampling tube 303, and the conical surface designed on the upper end face of the insert block 305 ensures that the heavy calcium carbonate can be discharged smoothly and fall into the ton bag, and the fourth motor 703 is started while the third motor 308 is started to rotate in the opposite direction.The output end of the fourth motor 703 drives the rotating shaft 702 to rotate the deflection transmission wheel 704. The rotation of the deflection transmission wheel 704 causes the transmission groove 705 to drive the spherical transmission block 710 and the moving rod 708 to move back and forth through the connecting shaft 709, so that the knocking plate 712 knocks the sampling tube 303. During the knocking process, the vibration generated by the knocking can make the particles attached to the inner wall of the sampling tube 303 and the spiral auger blade 310 The heavy calcium carbonate on the surface is loosened and falls off, further promoting the discharge of heavy calcium carbonate. When the knocking plate 712 contacts the sampling tube 303, the spring 715 can play a buffering role, reducing the damage caused by the impact force generated by the knocking to the sampling tube 303 and the material. At the same time, after the knocking is completed, the spring 715 can quickly reset the knocking plate 712 to prepare for the next knocking, ensuring the continuity and stability of the knocking action. The rubber protective pad 716 has good elasticity and flexibility, which can further buffer the impact force during knocking, avoid direct hard contact between the knocking plate 712 and the sampling tube 303, and effectively protect the sampling tube 303. The surface of the first limit block 707 and the second limit block 714 respectively limit the movement range of the moving rod 708 and the sliding rod 713 to prevent the moving rod 708 and the sliding rod 713 from detaching during the movement, thereby ensuring the matching accuracy and movement stability between the various components of the knocking assembly 7. When the heavy calcium carbonate in the sampling tube 303 is emptied, the third motor 308 and the fourth motor 703 are turned off, and then the two transparent arc-shaped collection boxes 318 are rotated along the sampling tube 303 as the axis until the arc-shaped inner clamping block 319 and the arc-shaped outer clamping block 320 on the two transparent arc-shaped collection boxes 318 slide along the corresponding arc-shaped inner clamping groove 315 and the arc-shaped outer clamping groove 317 respectively. When the arc-shaped inner clamping block 319 and the arc-shaped outer clamping block 320 slide to the corresponding arc-shaped inner placement groove 314 and the arc-shaped outer placement groove 316 respectively, the two transparent arc-shaped collection boxes 318 are removed.
