Description

Technical Field

[0001] The invention relates to the field of sampling and detection of anatase titanium dioxide, and in particular to a gradient sampling tool for sampling and detection of anatase titanium dioxide. Background Art

[0002] Anatase titanium dioxide is a white powdered inorganic pigment, the main component of which is titanium dioxide. It has a high refractive index and excellent hiding power and is widely used in coatings, plastics, papermaking, inks, rubber, cosmetics, food, and pharmaceutical industries. It is favored for its excellent whiteness, weather resistance, heat resistance, and chemical stability, and can significantly improve the appearance and performance of products. These characteristics of anatase titanium dioxide make it an indispensable material in many industrial applications.

[0003] There are many types of anatase titanium dioxide, such as A100, A101, A120, etc., all of which are in powder or granular form.

[0004] After the production of anatase titanium dioxide is completed, various tests need to be carried out, such as chemical composition analysis. The anatase titanium dioxide is ground into powder, and then the chemical composition contained in the anatase titanium dioxide is tested by testing equipment. The anatase titanium dioxide is placed in a specific medium, and the particle size distribution of the anatase titanium dioxide is tested by testing equipment. Anatase titanium dioxide is also subjected to aging tests. The color changes and physical property changes of anatase titanium dioxide in the natural environment are tested to evaluate the weather resistance. Existing testing devices usually need to use external operating equipment to extract different types of anatase titanium dioxide, and they also need to be placed in different testing devices for testing after extraction, which is cumbersome.

[0005] For example, Chinese patent publication number CN113848092A discloses a sampling device for titanium dioxide detection.

[0006] It includes an extraction mechanism, a sampling mechanism is sleeved on the outer side of the extraction mechanism, the bottom end of the sampling mechanism is fixedly connected with a lower pressure plate, the extraction mechanism includes an extraction tube, the outer side of the extraction tube is fixedly connected with the inner side of the sampling mechanism, the top end of the extraction tube is fixedly connected with a collecting box, and the bottom of the collecting box is fixedly connected with the top of the sampling mechanism.

[0007] However, the above sampling device still has some shortcomings in actual use:

[0008] 1. The above sampling device can only perform sampling and testing on a single type of titanium dioxide. When sampling and testing of multiple types and models of titanium dioxide are required, multiple devices are required to complete the process. Therefore, although the above device can sample titanium dioxide of different depths, it cannot simultaneously sample multiple different models of titanium dioxide.

[0009] 2. After the above sampling device completes sampling, it is unable to quickly transfer the sampled titanium dioxide to the corresponding detection device, and manual extraction of the titanium dioxide is required, which is a rather cumbersome process. Therefore, there is still room for improvement in the existing material extraction device.

[0010] Therefore, under the viewpoints stated above, there is still room for improvement in the existing titanium dioxide sampling device. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following combination Figures 1 to 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0042] The embodiment of the present application discloses a gradient sampling tool for sampling and detecting anatase titanium dioxide powder. It is explained that the gradient sampling tool for sampling and detecting anatase titanium dioxide powder is mainly used in the process of sampling and detecting titanium dioxide powder. In terms of technical effect, it is possible to uniformly sample the titanium dioxide powder on different conveyor belts by providing multiple sampling devices, and then transport the titanium dioxide powder to different detection devices for detection by diversion transmission; in particular, before detection, some titanium dioxide powder can be squeezed and crushed, so that the detection device can detect the titanium dioxide powder more accurately, further increasing the applicability of the present invention.

[0043] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a base plate 1, a support block 10, a support plate 11, a guard plate 12, a main shaft 13, a conveyor belt 14, a shaped plate 15 and a sampling unit 2. Several support blocks 10 distributed side by side are arranged on the base plate 1, a support plate 11 is arranged on the upper end of the support block 10, and a symmetrically distributed guard plate 12 is arranged on the upper end of the support plate 11. The support block 10 can support the guard plate 12 through the support plate 11.

[0044] Two symmetrically distributed main shafts 13 are rotatably arranged between two guard plates 12 on the same support plate 11. A plurality of conveyor belts 14 are arranged between the two main shafts 13, and the plurality of conveyor belts 14 correspond to the support plate 11 one by one. The main shaft 13 can rotate under the limit of the guard plate 12, and when it rotates, it can drive the conveyor belt 14 to move. One side of the main shaft 13 passes through the corresponding guard plate 12 and can be connected to the output shaft of an external drive motor to drive it to rotate.

[0045] A U-shaped plate 15 is jointly arranged at the upper ends of the two guard plates 12. A sampling unit 2 for sampling titanium dioxide is arranged on the U-shaped plate 15. After titanium dioxide of different models is produced, it can be poured onto the corresponding conveyor belt 14 for transportation. During the transportation process, the U-shaped plate 15 can prevent titanium dioxide from floating in the air and prevent external pollutants from falling on the conveyor belt 14 and polluting the titanium dioxide. The U-shaped plate 15 can also support the sampling unit 2. When sampling and detecting titanium dioxide, the sampling unit 2 is used to collect part of the titanium dioxide on the conveyor belt 14.

[0046] Continue to refer to Figure 1 、 Figure 2 and Figure 3 As shown in, that is, the sampling unit 2 for sampling titanium dioxide; specifically, the sampling unit 2 includes an arc-shaped groove 20, a flexible cloth 21, an arc-shaped strip plate 22, a rectangular block 23, a semi-circular groove 24, a rotating shaft 25, a horizontal plate 26 and a sampling member 3. A plurality of arc-shaped grooves 20 are opened on the outer side of the conveyor belt 14 and are evenly distributed along its extension section. A flexible cloth 21 is arranged between the inner walls of the arc-shaped grooves 20. A plurality of arc-shaped strip plates 22 corresponding to the arc-shaped grooves 20 one by one are arranged inside the conveyor belt 14. The flexible cloth 21 is made of a flexible material. In the initial state, both the outer side of the conveyor belt 14 and the surface of the flexible cloth 21 can support titanium dioxide. When the flexible cloth 21 is pressed by an external force, it will deform and sink into the arc-shaped strip plate 22.

[0047] A rectangular block 23 is arranged in the middle of the U-shaped plate 15. A semi-circular groove 24 with a radius corresponding to the arc-shaped groove 20 is opened inside the rectangular block 23. A rotating shaft 25 passing through the corresponding U-shaped plate 15 and semi-circular groove 24 is rotatably arranged among a plurality of rectangular blocks 23. The rotating shaft 25 can rotate under the limit of the rectangular block 23; a horizontal plate 26 is sleeved outside the rotating shaft 25 in the semi-circular groove 24, and when the rotating shaft 25 rotates, it can drive the horizontal plate 26 to rotate synchronously, so that the horizontal plate 26 can rotate in the corresponding semi-circular groove 24. And because the radius of the semi-circular groove 24 is the same as that of the arc-shaped groove 20, when the swing plate 36 swings to be in contact with the flexible cloth 21, continuing to swing at this time will drive the flexible cloth 21 to deform.

[0048] The angles of the transverse plates 26 in the several semicircular grooves 24 are inconsistent. An avoidance groove (not shown in the figure) for avoiding the arc-shaped strip 22 is opened on the outer side of the main shaft 13 between the two guard plates 12 on the same support plate 11. Because the arc-shaped strip 22 can be driven to move synchronously when the conveyor belt 14 moves, in order to avoid interference with the main shaft 13 after the arc-shaped strip 22 moves to correspond to the main shaft 13, an avoidance groove is provided to prevent the arc-shaped strip 22 from interfering with the main shaft 13.

[0049] A sampling piece 3 for sampling the titanium dioxide on the conveyor belt 14 is provided on one side of the swinging direction of the transverse plate 26 . The swinging plate 36 can synchronously drive the sampling piece 3 to sample the titanium dioxide on the flexible cloth 21 .

[0050] Reference Figure 4 and Figure 5 As shown, the sampling member 3 is used to sample the titanium dioxide on the conveyor belt 14; specifically, the sampling member 3 includes an arc plate 30, an arc cavity 31, a screw rod 1 32, a circular groove 33, a cylinder 34, a baffle plate 35, a swing plate 36, a foam ball 37, a screw rod 2 38, an annular groove 39, a limit plate 310, a driving groove 311, a driving plate 312 and a diversion unit 4, the arc plate 30 is arranged on one side of the transverse plate 26, and the transverse plate 26 can drive the arc plate 30 in the semicircular groove 24 The arc plate 30 has an arc cavity 31 with one end extending through the other side thereof, and an auger rod 32 is rotatably arranged on the inner wall of the arc cavity 31. The upper end of the arc plate 30 has a circular groove 33 extending through the arc cavity 31 and corresponding to the upper end of the auger rod 32. The auger rod 32 can rotate in the arc cavity 31, and one end of the auger rod 32 passes through the outer side of the arc plate 30 for connection with the output shaft of an external drive motor to provide rotational force for it.

[0051] The rectangular block 23 is also provided with a strip groove corresponding to the circular groove 33, and a cylinder 34 is provided in the strip groove. A blocking plate 35 corresponding to the outer side of the auger rod 32 is provided on the inner wall of one side of the arc cavity 31. A swing plate 36 is provided at one end of the blocking plate 35 in a hinged manner, and a foam ball 37 is provided on one side of the swing plate 36. When there is titanium dioxide on the outer side of the auger rod 32, the auger rod 32 rotates, and the titanium dioxide is pushed by the cooperation of the blocking plate 35 and the swing plate 36. The powder is transmitted out of the circular groove 33, so that the titanium dioxide enters the cylinder 34 through the circular groove 33. When sampling is needed, the arc plate 30 is driven by the cross plate 26 to contact the flexible cloth 21, so that the flexible cloth 21 is deformed, and the titanium dioxide on the flexible cloth 21 will also enter the curved surface of the flexible cloth 21. At this time, the swing plate 36 drives the arc plate 30 to continue to move, and the titanium dioxide on the flexible cloth 21 will enter the arc cavity 31 through the opening of the arc cavity 31.

[0052] At this time, the swing plate 36 is affected by gravity and is distributed vertically with the conveyor belt 14, so that the titanium dioxide can enter the side of the baffle plate 35 facing the auger rod 32, and finally enter the spiral blades of the auger rod 32. The cross plate 26 continues to drive the arc plate 30 to move. At this time, the foam ball 37 is supported by the titanium dioxide on the upper side of the flexible cloth 21, driving the swing plate 36 so as not to separate the arc cavity 31 from the auger rod 32. Only when the cross plate 26 is completely separated from the flexible cloth 21, the flexible cloth 21 rebounds to be flush with the outside of the conveyor belt 14, and the swing plate 36 is affected by gravity and swings back to the initial position. Since the amount of titanium dioxide on the outside of the auger rod 32 is small, it is only necessary for the swing plate 36 to be close to the outside of the auger rod 32, and the auger rod 32 can be rotated to transfer the titanium dioxide to the cylinder 34.

[0053] It should be noted that, during sampling, the conveyor belt 14 is in a stationary state.

[0054] The auger rod 2 38 is located in the cylinder 34, and an annular groove 39 is provided on the outer side of the auger rod 2 38. A limit plate 310 with one end located in the annular groove 39 is provided on the inner wall of the cylinder 34. A driving groove 311 is provided on the upper end of the auger rod 1 32, and a driving plate 312 located in the corresponding driving groove 311 is provided on the lower end of the auger rod 2 38. A diversion unit 4 for diverting titanium dioxide is provided at one end of the cylinder 34 located outside the rectangular block 23. The limit plate 310 limits the auger rod 2 38 through the annular groove 39. When the auger rod 1 32 swings to correspond to the auger rod 2 38, the limit plate 310 on one side of the auger rod 2 38 It will be located in the driving groove 311 on the side of the corresponding auger rod 1 32. At this time, the auger rod 1 32 can drive the auger rod 2 38 to rotate through the cooperation of the driving groove 311 and the driving plate 312, so that the auger rod 2 38 can drive the titanium dioxide in the cylinder 34 to move upward. Since the angles of the multiple cross plates 26 on the rotating shaft 25 are inconsistent, when the auger rod 1 32 on an arc plate 30 corresponds to the auger rod 2 38, the auger rods 1 32 on the other arc plates 30 must not correspond to the auger rod 2 38, that is, the titanium dioxide in the multiple arc cavities 31 is transmitted to the diversion unit 4 step by step.

[0055] Reference Figure 6As shown, the diversion unit 4 is used to divert titanium dioxide; specifically, the diversion unit 4 includes a cluster tube 40, a connecting tube 41, a diversion tube 42, an auger rod three 43, a transmission tube 44 and a detection unit 5. The cluster tube 40 is commonly arranged at one end of a plurality of cylinders 34 and is connected thereto, and the titanium dioxide in the cylinder 34 can enter the cluster tube 40; the outer side of the cluster tube 40 is also provided with a connecting tube 41 connected thereto, and the other end of the connecting tube 41 is provided with a diversion tube 42 connected thereto, and the cluster tube 40 and the diversion tube 42 are both rotatably provided with an auger rod three 43, and one side of the two auger rods three 43 passes through the corresponding diversion tube 42 and one end of the cluster tube 40 and are connected by belt drive.

[0056] The spiral directions of the two auger rods 43 are opposite. Two transmission tubes 44 are arranged on the outside of the diversion tube 42 and are respectively located between the corresponding convex plates 15. The auger rods 43 in the cluster tube 40 and the diversion tube 42 can rotate synchronously by belt drive. When the auger rod 43 in the cluster tube 40 rotates, the titanium dioxide inside the cluster tube 40 can be driven to move toward the connecting tube 41. The titanium dioxide can enter the diversion tube 42 through the connecting tube 41, and then driven by the auger rod 43 inside the diversion tube 42, the titanium dioxide is driven to move toward the transmission tube 44.

[0057] One end of the auger rod 43 on one side passes through the outside of the corresponding cluster tube 40, and is connected to the main shaft 13 on one side by a belt drive, so that when the main shaft 13 rotates, it can drive it to rotate synchronously; the end of the transmission tube 44 is provided with a detection unit 5 for detecting titanium dioxide. According to different test items, titanium dioxide enters the corresponding detection unit 5 through different transmission tubes 44 for detection.

[0058] Reference Figure 7 , Figure 8 and Fig. 9 As shown, a detection unit 5 for detecting titanium dioxide is arranged between the guard plates 12 on two different support plates 11; specifically, the detection unit 5 includes a detection box 50, a limit cylinder 51, a reciprocating screw 52, ​​a support tray 53, a sliding groove 54, a sliding plate 55, a collision plate 56, a storage groove 57, a spring push rod 58, a conical block 59, a discharge trough 510 and a gearbox 511, and the two detection boxes 50 are respectively arranged between two corresponding guard plates 12, and the two detection boxes 50 are respectively connected to the corresponding transmission tubes 44, and a spectrophotometer and a weather resistance test equipment are arranged in the detection box 50 on one side, the guard plates 12 can support the corresponding detection boxes 50 respectively, and the transmission tube 44 can transmit titanium dioxide to the corresponding detection box 50, the spectrophotometer is used to test the color and color characteristics of titanium dioxide, and the weather resistance test equipment is mainly used to evaluate the aging performance of materials in natural or simulated environments.

[0059] A limiting cylinder 51 is provided in the detection box 50 on the other side, and a reciprocating screw 52 is rotatably provided on the inner wall of the detection box 50, and a bearing tray 53 is threadedly provided on the outer side of the reciprocating screw 52, ​​and a sliding groove 54 is opened on the inner wall of the limiting cylinder 51, and a sliding plate 55 located in the sliding groove 54 is provided on the outer side of the bearing tray 53. The reciprocating screw 52 can rotate in the corresponding detection box 50, and the sliding groove 54 can limit and guide the bearing tray 53 through the sliding plate 55. The inner wall of the limiting cylinder 51 is tightly attached to the outer side of the bearing tray 53, and the reciprocating screw 52 can drive the bearing tray 53 to move in the up and down directions when rotating.

[0060] A collision plate 56 is also provided on the inner wall of the limiting cylinder 51, and the reciprocating screw rod 52 slides through the middle of the collision plate 56, and one end of the transmission tube 44 located in the corresponding detection box 50 penetrates to the bottom of the collision plate 56, and the titanium dioxide in the transmission tube 44 can fall onto the supporting tray 53. The supporting tray 53 is used to support the titanium dioxide. When the supporting tray 53 drives the titanium dioxide to connect with the collision plate 56, the adhesion between the two can cause some larger particles of titanium dioxide to break, which is convenient for subsequent testing.

[0061] A receiving groove 57 corresponding to the end of the transmission tube 44 is provided at the bottom of the collision disk 56, and a spring push rod 58 is arranged inside the collision disk 56. The telescopic end of the spring push rod 58 passes through the bottom of the collision disk 56 and is provided with a conical block 59 corresponding to the receiving groove 57. A particle size analyzer is arranged in the detection box 50, and the receiving groove 57 is used to store the conical block 59. In the initial state, the spring push rod 58 pushes the conical block 59 to be located at the lower end of the collision disk 56, and the titanium dioxide discharged from the corresponding end of the transmission tube 44 will also slide onto the receiving tray 53 through the inclined surface on the outer side of the conical block 59. When the receiving tray 53 rises to contact the bottom of the conical block 59, it will continue to push the conical block 59 to move into the receiving groove 57, so that the moving trajectory of the receiving tray 53 will not be blocked by the conical block 59, and it also prevents the titanium dioxide corresponding to the end of the transmission tube 44 on the receiving tray 53 from being squeezed due to the existence of the cavity at the end of the transmission tube 44.

[0062] When the tray 53 descends, the spring push rod 58 continues to push the conical block 59 to the lower end of the collision plate 56. The particle size analyzer is used to detect the particle size distribution data of titanium dioxide. Before the detection, the titanium dioxide needs to be evenly distributed on the tray 53. The tray 53 and the collision plate 56 squeeze each other to achieve the above-mentioned test conditions; one side of the two test boxes 50 is provided with a discharge chute 510 that penetrates the interior thereof, and one side of the limiting cylinder 51 is also provided with a discharge chute 510. The titanium dioxide that has completed the test is discharged out of the test box 50 through the corresponding discharge chute 510 under the drive of the corresponding "spectrophotometer", "weather resistance test equipment" and "particle size analyzer".

[0063] At the upper end of the detection box 50 on one side, a gearbox 511 is provided. The upper end of the reciprocating lead screw 52 passes through the outer wall of the corresponding test box and is connected to the connecting shaft of the gearbox 511. And the connecting shaft on the other side of the gearbox 511 is connected to the corresponding main shaft 13 by means of belt drive. That is, when the main shaft 13 rotates, the gearbox 511 is driven to operate by belt drive, and the gearbox 511 drives the reciprocating lead screw 52 to rotate. In order to prevent the rotation speed of the reciprocating lead screw 52 from being too fast, so as not to indirectly affect the detection accuracy of the particle size analyzer, the gearbox 511 is used to reduce the rotational force transmitted by the main shaft 13.

[0064] It should be noted that the "spectrophotometric colorimeter", "weather resistance test equipment" and "particle size analyzer" mentioned in the above implementation process are all common knowledge, so they will not be elaborated in this implementation process.

[0065] Example Two: Refer to Fig.10 As shown, on the basis of Example One, in order to be able to transport titanium dioxide of different models in the shunt pipe 42 to the corresponding detection box 50, an opening and closing unit 6 is provided on one side of the two transmission pipes 44; specifically, the opening and closing unit 6 includes an opening and closing plate 60, a double-shaft cylinder 61 and an opening and closing groove 62. The two opening and closing plates 60 are slidably inserted through the connection between the corresponding transmission pipe 44 and the shunt pipe 42. The upper end of the U-shaped plate 15 in the middle is provided with a double-shaft cylinder 61 through a cylinder seat, and the propulsion shafts on both sides of the double-shaft cylinder 61 are respectively connected to the corresponding opening and closing plates 60. An opening and closing groove 62 corresponding to the inner diameter of the transmission pipe 44 is also opened on the opening and closing plate 60. The double-shaft cylinder 61 can drive the two opening and closing plates 60 to move synchronously. And when the opening and closing groove 62 on the opening and closing plate 60 corresponds to the transmission pipe 44, the shunt pipe 42 can transmit the titanium dioxide inside to the transmission pipe 44. When the opening and closing groove 62 on one opening and closing plate 60 corresponds to the transmission pipe 44, the opening and closing groove 62 on the other opening and closing plate 60 will not correspond to the transmission pipe 44, and the corresponding opening and closing plate 60 will block the transmission pipe 44. Therefore, for which test the titanium dioxide in the corresponding shunt pipe 42 needs to be carried out, only need to drive the corresponding opening and closing plate 60 by the double-shaft cylinder 61 to解除 the blockage of the adjacent transmission pipe 44.

[0066] During operation: The first step is to pour titanium dioxide of different models that have been produced onto the corresponding conveyor belt 14, and then start the conveyor belt 14 to transport the titanium dioxide.

[0067] The second step: During the transportation of titanium dioxide, the sampling unit 2 can drive the sampling part 3 to take materials from the titanium dioxide on the conveyor belt 14, and during the process of taking materials, the U-shaped plate 15 at the upper end of the protection plate 12 is used to prevent the titanium dioxide from floating in the air.

[0068] Step 3: After the sampling piece 3 completes the sampling of titanium dioxide, it can cooperate with the diversion unit 4 to transfer the extracted titanium dioxide to the cluster tube 40 of the diversion unit 4, and then transfer it to the diversion tube 42 through the cluster tube 40. With the cooperation of the opening and closing unit 6, the diversion unit 4 transfers the titanium dioxide to the corresponding detection box 50 for detection.

[0069] Step 4: The detection unit 5 tests the color and color characteristics of the titanium dioxide through a spectrophotometer. The weather resistance test equipment is used to evaluate the aging performance of the material in a natural or simulated environment. In addition, the titanium dioxide is evenly spread on the tray 53 with the cooperation of the collision plate 56, and some large particles of titanium dioxide are crushed, so that the particle size distribution data of the titanium dioxide can be detected by the particle size analyzer.

[0070] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
