Description

A detection device and method for the production of active nano-calcium carbonate Technical Field

[0001] This invention belongs to the field of visual inspection technology, specifically a detection device and method for the production of active nano-calcium carbonate. Background Technology

[0002] Activated nano-calcium carbonate, as a surface-modified nanoscale powder material, is widely used in plastics, rubber, coatings, papermaking and other fields due to its excellent dispersibility, reinforcement and compatibility. Its product quality directly determines the performance of downstream products.

[0003] The production process of activated nano calcium carbonate mainly includes: raw material pretreatment, calcination, digestion, carbonization, surface modification, drying, and finished product packaging. Among them, the drying process is the key link to ensure the performance of the finished product. The state of the powder after drying directly affects the dispersibility, flowability, and appearance quality of the final product. At present, the industry usually uses a device consisting of an industrial camera, a light source, and an image analysis system to capture and identify defects such as agglomerates, abnormal color spots, and large particle impurities in the powder using image recognition algorithms.

[0004] However, in actual production, the dried active nano-calcium carbonate powder is ultra-fine nanoscale. During the process of being discharged from the dryer outlet and entering the conveying stage, due to the light weight and high fluidity of the powder particles, a large amount of dust is easily generated. The suspended dust scatters light, destroys the uniformity of illumination, causes a decrease in image contrast, makes it difficult to distinguish between powder defects and background interference, and high concentrations of dust will form a "fog effect", obscuring the moving powder target, causing the camera to be unable to clearly capture the true appearance characteristics of the powder particles, thus leading to misjudgment and missed judgment of defects, seriously reducing the accuracy and reliability of visual inspection.

[0005] Therefore, the present invention provides a detection device and method for the production of active nano-calcium carbonate. Summary of the Invention

A toothed plate that meshes with the transmission gear is fixedly installed inside the positioning block. A transmission rod is fixedly connected to the inner wall of the connecting pipe. A first bevel gear is fixedly installed on the transmission rod. A second bevel gear that meshes with the first bevel gear is fixedly installed at the top of the smoothing claw.

[0010] The suction structure includes a negative pressure pump and a first air tube. The negative pressure pump is located below the shelf. One end of the first air tube is connected to the negative pressure end of the negative pressure pump, and the other end of the first air tube is connected to the receiving box.

[0011] A discharge box is provided below the shelf, and an airflow box is fixedly installed on the discharge box. The airflow box and the discharge box are connected by an air port. A rotating rod is rotatably installed inside the discharge box, and a material distribution blade is fixedly installed on the outer wall of the rotating rod. The top and bottom ends of the material distribution blade are in contact with the discharge box. A gas-solid diversion area is opened at the top of the discharge box, and a discharge pipe is provided at the bottom of the discharge box. The positive pressure end of the negative pressure pump is connected to the airflow box through a second air pipe.

[0012] One end of the rotating rod extends out of the top of the discharge box. The outer wall of the rotating rod is connected by a threaded baffle plate for partially blocking the gas-solid separation zone. There is a space between the baffle plate and the gas-solid separation zone. An air cylinder is provided on the top of the discharge box. A piston is slidably installed inside the air cylinder. A first connecting pipe and a second connecting pipe are provided on the air cylinder. The other end of the second connecting pipe extends into the interior of the baffle plate. A one-way valve is provided on both the first connecting pipe and the second connecting pipe.

[0013] A reciprocating lead screw is fixedly installed on the top of the piston. A drive shaft is threadedly connected to the outer wall of the reciprocating lead screw. A driven gear is fixedly installed on the top of the drive shaft. A driving gear that meshes with the driven gear is fixedly installed on the top of the rotating rod.

[0014] A method for using a testing device for the production of active nano-calcium carbonate includes the following steps: S1: Pull out the discharge bin, and the collecting box drives the smoothing claw to smooth the active nano-calcium carbonate powder on the placement plate; S2: The negative pressure pump works, and through the connecting pipe, negative pressure is created in the collecting box, which draws the floating material above the placement plate into the receiving box and sends it into the discharge box; S3: The material enters the discharge box, the gas is discharged from the gas-solid separation zone, and the rotating rod drives the distributing blades to scrape the calcium carbonate powder on the gas-solid separation zone and push it to the discharge pipe for discharge.

[0015] The beneficial effects of the present invention are as follows: 1. The detection device and method for the production of active nano-calcium carbonate described in the present invention control the material collection box to slide above the placement plate through the control mechanism. The material collection box drives the smoothing claw to move synchronously. The smoothing claw smooths the calcium carbonate powder on the placement plate, ensuring that the powder surface height is uniform, so that the image in the field of view of the visual inspection equipment is in a clear focus range. The suction mechanism creates a negative pressure inside the material collection box, and quickly removes the floating material between the placement plate and the visual inspection equipment through the feed port, completely eliminating the hidden dangers of dust scattering light and forming a fog effect. The above structure works together to avoid the problems of decreased image contrast and false or missed defect detection caused by dust, and significantly improves the accuracy and reliability of visual inspection.

[0016] 2. The detection device and method for producing active nano-calcium carbonate according to the present invention uses a suction mechanism to send the sucked-in calcium carbonate float into the discharge box. The gas-solid separation zone separates the gas phase and solid phase. The separating blades rotate under the drive of the rotating rod, scraping off the solid float at the top and bottom of the discharge box and pushing it out of the discharge pipe, avoiding the float from re-suspending and causing waste, and realizing resource recycling. At the same time, the baffle plate intermittently switches the blocking area of ​​the gas-solid separation zone. With the gas back-blowing action of the air cylinder and piston, the separation holes in the area blocked by the baffle plate can be effectively cleaned, preventing the calcium carbonate float from blocking the channel, ensuring stable gas-solid separation efficiency, and further improving the continuity and practicality of the device operation.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] An embodiment of the present invention discloses a detection device for the production of active nano-calcium carbonate, comprising a dryer 1, a discharge hopper 2 located inside the dryer 1, a shelf 3 detachably mounted on the discharge hopper 2, and a vision inspection device 4. Positioning blocks 5 are provided on both sides of the discharge hopper 2, and a collection box 6 is slidably mounted between the two positioning blocks 5. A smoothing claw 12 is rotatably mounted on the bottom of the collection box 6. The collection box 6 can slide between the two positioning blocks 5. When the collection box 6 drives the smoothing claw 12 to slide above the shelf 3, the rotation of the smoothing claw 12 can smooth the calcium carbonate powder on the shelf 3, reducing the accumulation of calcium carbonate powder and making its surface height uniform. This ensures that the image within the field of view of the vision inspection device 4 is within a clear focus range, guaranteeing image clarity and thus improving the detection effect.

[0022] The positioning block 5 has a first winding wheel 22 at one end and a second winding wheel 25 at the other end. The first winding wheel 22 is fixedly connected to the collection box 6 via a first connecting rope 23, and the second winding wheel 25 is connected to the collection box 6 via a second connecting rope 26. The positioning block 5 has a control mechanism inside, which controls the rotation of the first winding wheel 22 and the second winding wheel 25 by sliding the discharge bin 2, thereby realizing the sliding of the collection box 6. When the discharge bin 2 is pulled out of the dryer 1, the control mechanism can control the first winding wheel 22 to wind up the first connecting rope 23 and the second winding wheel 25 to unwind the second connecting rope 26, while pulling the collection box 6 toward the dryer 1. When the discharge bin 2 is pushed into the dryer 1, the second winding wheel 25 winds up the second connecting rope 26 and the first winding wheel 22 unwinds the first connecting rope 23, at which point the collection box 6 will slide away from the dryer 1.

[0023] The material collection box 6 has a feed inlet 11. The two sides of the material collection box 6 are rotatably connected to the receiving box 16 through the connecting pipe 17. The dryer 1 has a suction mechanism connected to the receiving box 16 on one side, which is used to suck the floating material on the storage plate 3 into the receiving box 16 through the material collection box 6.

[0024] The feed inlets 11 are located on both sides of the collection box 6. Through the suction mechanism, the inside of the receiving box 16 is made to be under negative pressure, and the inside of the collection box 6 is also made to be under negative pressure. Therefore, when the collection box 6 slides above the shelf 3, the floating material between the shelf 3 and the vision inspection device 4 can be sucked into the collection box 6 through the feed inlets 11. This solves the problem that the calcium carbonate floating material will scatter and absorb light, resulting in blurry images, reduced contrast, and even light spots, halos, or ghosting. This improves the detection effect of the vision inspection device 4.

[0025] By setting up the control mechanism, when the discharge bin 2 is pulled out, the collection box 6 can be moved while the smoothing claw 12 set at the bottom smooths the calcium carbonate powder on the placement plate 3, which solves the problem of uneven calcium carbonate powder causing blurring in the visual inspection area, thereby improving the inspection effect.

[0026] The control mechanism includes a control wheel 20, a control rope 21, a first coil spring 24, and a second coil spring 27. The control wheel 20 is fixedly connected to the first take-up wheel 22 and is located inside the positioning block 5 near one end of the dryer 1. The control wheel 20 is connected to the dryer 1 through the control rope 21. The first coil spring 24 is connected to the positioning block 5 through the first take-up wheel 22, and the second coil spring 27 is connected to the positioning block 5 through the second take-up wheel 25.

[0027] When the discharge hopper 2 is pulled out of the dryer 1, the control rope 21 drives the control wheel 20 to unwind, and at the same time controls the first take-up wheel 22 to wind up the first connecting rope 23, causing the first coil spring 24 to deform and store elastic potential energy. At this time, the second take-up wheel 25 unwinds the second connecting rope 26, and the second coil spring 27 deforms and stores elastic potential energy. During the period when the collection box 6 slides toward the dryer 1, the smoothing claw 12 smooths the calcium carbonate powder on the placement plate 3. At the same time, with the cooperation of the negative pressure mechanism, the collection box 6 absorbs the floating calcium carbonate material in the air, thereby improving the detection quality of the visual inspection equipment 4.

[0028] When the discharge bin 2 is pushed into the dryer 1, the first coil spring 24 resets, driving the first take-up wheel 22 to unwind the first connecting rope 23, while the control wheel 20 winds up the control rope 21 and the second take-up wheel 25 winds up the second connecting rope 26, pulling the collection box 6 away from the dryer 1.

[0029] One end of the connecting pipe 17 is rotatably connected to the collection box 6, and the other end is fixedly mounted on the outer wall with a transmission gear 18. The positioning block 5 is fixedly mounted with a toothed plate 19 that mates with the transmission gear 18. The inner wall of the connecting pipe 17 is fixedly connected to a transmission rod 13, and a first bevel gear 14 is fixedly mounted on the transmission rod 13. The top of the smoothing claw 12 is fixedly mounted with a second bevel gear 15 that meshes with the first bevel gear 14.

[0030] When the collection box 6 slides inside the positioning block 5, the transmission gear 18 set on the outer wall of the connecting pipe 17 will rotate under the action of the toothed plate 19, and at the same time drive the transmission rod 13 to rotate. Through the cooperation of the first bevel gear 14 and the second bevel gear 15, the smoothing claw 12 will rotate inside the collection box 6, thereby smoothing the calcium carbonate powder on the placement plate 3.

[0031] The suction structure includes a negative pressure pump 7 and a first air pipe 8. The negative pressure pump 7 is located below the shelf 3. One end of the first air pipe 8 is connected to the negative pressure end of the negative pressure pump 7, and the other end of the first air pipe 8 is connected to the receiving box 16.

[0032] By starting the negative pressure pump 7, the inside of both the receiving box 16 and the collecting box 6 can be made negative pressure through the first air pipe 8, and then the calcium carbonate floating material can be absorbed through the feed inlet 11.

[0033] Below the shelf 3 is a discharge box 10, and an airflow box 28 is fixedly installed on the discharge box 10. The airflow box 28 and the discharge box 10 are connected through an air port 29. A rotating rod 30 is rotatably installed inside the discharge box 10. A material distribution blade 31 is fixedly installed on the outer wall of the rotating rod 30. The top and bottom ends of the material distribution blade 31 are in contact with the discharge box 10. A gas-solid diversion area 32 is opened at the top of the discharge box 10. A discharge pipe is provided at the bottom of the discharge box 10. The positive pressure end of the negative pressure pump 7 is connected to the airflow box 28 through a second air pipe 9.

[0034] When the negative pressure pump 7 starts, it will send the calcium carbonate float sucked in through the feed port 11 into the airflow box 28 through the second air pipe 9. At this time, the airflow carries the calcium carbonate float through the air port 29 and enters the inner cavity of the discharge box 10. The gas phase is discharged from the gas-solid separation zone 32, and some of the solid phase will fall to the bottom of the discharge box 10 under the action of gravity. Some of the solid phase will remain at the top of the discharge box 10 under the action of the airflow. At this time, the rotating rod 30 drives the distributing blade 31 to rotate inside the discharge box 10, which can scrape off the calcium carbonate float at the bottom and top of the discharge box 10 and push the calcium carbonate float to move inside the discharge box 10 until the calcium carbonate float is discharged from the discharge pipe. The calcium carbonate float discharged in this way will not be affected by the airflow and will be suspended in the air. The calcium carbonate float can be recovered relatively stably to avoid waste.

[0035] One end of the rotating rod 30 extends out of the top of the discharge box 10. The outer wall of the rotating rod 30 is connected by a threaded baffle plate 33 for partially blocking the gas-solid diversion zone 32. There is a space between the baffle plate 33 and the gas-solid diversion zone 32. The baffle plate 33 can block part of the gas-solid diversion zone 32. At this time, the gas in the other part of the gas-solid diversion zone 32 that is not blocked can be discharged normally. The rotating rod 30 and the baffle plate 33 are connected by a reciprocating threaded groove. When the rotating rod 30 rotates continuously, it will intermittently control the baffle plate 33 to switch the blocking area on the gas-solid diversion zone 32.

[0036] An air cylinder 37 is provided on the top of the discharge box 10. A piston 38 is slidably installed inside the air cylinder 37. A first connecting pipe 39 and a second connecting pipe 40 are provided on the air cylinder 37. The other end of the second connecting pipe 40 extends into the interior of the baffle plate 33. A one-way valve is provided on both the first connecting pipe 39 and the second connecting pipe 40.

[0037] The other end of the first connecting pipe 39 is connected to the outside of the air cylinder 37. The one-way valve on the first connecting pipe 39 can only allow external gas to enter the air cylinder 37. The one-way valve on the second connecting pipe 40 can only allow gas inside the air cylinder 37 to enter the inner cavity of the baffle plate 33 through the second connecting pipe 40.

[0038] Therefore, when the piston 38 slides upward inside the gas cylinder 37, gas can be drawn into the gas cylinder 37 through the first connecting pipe 39. Then, as the piston 38 slides downward inside the gas cylinder 37, the gas inside the gas cylinder 37 can be sent into the baffle plate 33. This gas can then backflush the gas-solid separation zone 32 that is blocked by the baffle plate 33, preventing the calcium carbonate float from clogging the holes in the gas-solid separation zone 32 and thus affecting the discharge of the gas phase.

[0039] A reciprocating screw 34 is fixedly mounted on the top of the piston 38. A drive shaft 41 is threadedly connected to the outer wall of the reciprocating screw 34. A driven gear 36 is fixedly mounted on the top of the drive shaft 41. A drive gear 35 that meshes with the driven gear 36 is fixedly mounted on the top of the rotating rod 30.

[0040] The rotating rod 30 is connected to the motor. The motor drives the rotating rod 30 to rotate, which controls the rotation of the drive gear 35. This, in turn, causes the driven gear 36 to drive the transmission shaft 41 to rotate, causing the reciprocating screw 34 to drive the piston 38 to slide up and down inside the air cylinder 37. This, together with the first connecting pipe 39 and the second connecting pipe 40, sends gas into the interior of the baffle plate 33 and backflushs the gas-solid separation zone 32 blocked by the baffle plate 33. This reduces the impact of gas phase discharge and further improves the efficiency of calcium carbonate float recovery.
