Description

Technical Field

[0001] The present invention relates to the technical field of sintering machines, and specifically to a device for stratified sampling of sintering machine mixture materials. Background Art

[0002] Sintering machines are mainly used for sintering operations in metallurgical sintering plants and are suitable for sintering various ore powders. A sintering machine includes multiple carriages connected end to end, forming a ring and operating in an elliptical closed cycle on tracks. The influencing factors of the production capacity of a sintering machine are: First, the functional conditions of the equipment; Second, the material conditions used for sintering; Third, the granulation capacity of the sintering equipment and the reasonable segregation level of the feeding facilities.

[0003] In this regard, the prior art patent publication number: CN107290172, discloses a device and method for stratified sampling of sintering machine mixture materials, which relates to the technical field of sintering, and the technical problem to be solved is to provide a device for stratified sampling of sintering machine mixture materials that can perform stratified sampling and is easy to operate. It includes a frame body, a plug board, and a stratified board. The top of the frame body is open, and the bottom is sealed by a bottom plate. One side of the frame body is an open surface, and the plug board can seal the open surface; a stratified notch is provided on the surface opposite to the open surface, and the stratified board can be inserted from the stratified notch to divide the interior of the frame body into multiple layers. The method for stratified sampling of sintering machine mixture materials is as follows: First, place the frame body on an unloaded carriage, and then perform feeding; after the sintering mixture is fed, leave 1 - 3 carriages at the periphery without ignition, stop the sintering machine, insert the plug board, lift out the frame body, insert the stratified board, fill the holes of the carriage from which the frame body is lifted out, and then resume sintering production; finally, perform stratified sampling and detection on the mixture materials in the frame body to guide production and improve the sintering process.

[0004] However, in actual use, when performing stratified sampling on the mixture materials of the sintering machine, during the sampling process, the sampling frame directly contacts the mixture materials, and then the mixture materials are stratified by the stratified board. However, in actual use, the overall sealing effect between the stratified board and the upper layer of the mixture materials is poor, which will affect the mixture materials between layers and the subsequent detection results. At the same time, during the stratified sampling process, the distribution of the mixture materials in the sampling frame is relatively sparse. When performing sampling and detection later, a low sampling quantity will also affect the detection results. Therefore, the overall stratified sampling has certain limitations. Thus, improving and perfecting the above problems has become an urgent problem to be solved at present. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0032] Please refer to Figures 1 - 10 , an embodiment provided by the present invention:

[0033] A layered sampling device for sintering machine mixture. The drive motor 7, worm 18 and worm gear 25 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here. It includes a sampling frame 1. A connecting frame 2 is installed on the top surface of the sampling frame 1. Sealing slots 3 are opened on the right side of the sampling frame 1. There are two groups of sealing slots 3, which are respectively arranged at the one-third and two-thirds positions on the right side of the sampling frame 1. On one side of the surface of the sampling frame 1, a first mounting frame 4 and a second mounting frame 5 are fixedly connected in sequence from top to bottom. The first mounting frame 4 and the second mounting frame 5 are respectively adapted to the two groups of sealing slots 3 on the right side of the sampling frame 1. A first layered plate 6 is installed inside the first mounting frame 4. The first layered plate 6 is adapted to the sealing slot 3. A first sliding groove is opened on the lower surface of the first mounting frame 4. A moving plate 10 is installed through the inside of the first sliding groove on the lower surface of the first layered plate 6. A first operation frame 20 is installed on the back surface of the sampling frame 1. A second operation frame 36 is installed on the front surface of the sampling frame 1. A rotating shaft 22 is inserted and installed inside the first operation frame 20. A protective housing 21 is installed on the right side of the first operation frame 20. The connecting ends of the second bevel gear column 16 and the connecting bevel gear column 17 are installed inside the protective housing 21. The connecting bevel gear column 17 is installed inside the protective housing 21. An installation cylinder 23 is fixedly connected to the outer surface of the rotating shaft 22. A knocking block 24 is installed on the outer surface of the installation cylinder 23. The knocking block 24 abuts against the back surface of the sampling frame 1. A worm gear 25 is installed on one side of the surface of the rotating shaft 22. The worm gear 25 meshes with the worm 18. Sliding grooves 26 are opened on the upper and lower surfaces of the second mounting frame 5. A second layered plate is installed at the lower end of the moving plate 10. A connecting plate 32 is installed at the lower end of the second layered plate. The connecting plate 32 is slidably installed in the lower end worm gear 25 of the second mounting frame 5. A rotating sealing door 39 is movably installed at the lower end of the sampling frame 1 through a hinge. A positioning frame 27 is fixedly connected to the lower surface of the sampling frame 1. A resisting block 28 is slidably installed inside the positioning frame 27. A mounting block 29 is fixedly connected to the top surface of the resisting block 28. A bottom block 38 is fixedly connected to the right side of the positioning frame 27. A telescopic cylinder 31 is installed on the left side of the bottom block 38. A telescopic column 30 is arranged inside the telescopic cylinder 31. A spring body 40 is installed on the inner side wall of the telescopic cylinder 31. The left side of the spring body 40 contacts the right side of the telescopic column 30. The left side of the telescopic column 30 is installed on the right side surface of the resisting block 28. A positioning plate 33 is fixedly connected to the left side of the connecting plate 32. A resisting plate 34 is installed on the left side of the positioning plate 33. The left side of the resisting plate 34 abuts against the right side surface of the mounting block 29. At the same time, when the second layered plate inside the second mounting frame 5 moves towards the inside of the sampling frame 1, at this time, the second layered plate will drive the connecting plate 32 to move through the sliding groove 26 at the lower end of the second mounting frame 5. Then, the connecting plate 32, the positioning plate 33 and the resisting plate 34 will move to the left following the resisting plate 34. Then, when the resisting plate 34 abuts against the right side surface of the mounting block 29,It can drive the mounting block 29 to move to the left. Then, the mounting block 29 will drive the abutting block 28 to move. At this time, the position of the abutting block 28 is limited by the positioning frame 27, and at this time, the rotating sealing door 39 is in the Figure 1 state. Then, when the abutting block 28 continues to move, the abutting block 28 can abut against the right surface of the rotating sealing door 39. Then, through the abutment of the abutting block 28, the rotating sealing door 39 can be driven to rotate. Then, the rotating sealing door 39 will slowly fit against the lower surface of the sampling frame 1 following the movement of the abutting block 28 until the abutting block 28 stably abuts the rotating sealing door 39 against the lower surface of the sampling frame 1. Thus, when the first stratified plate 6 and the second stratified plate enter the interior of the sampling frame 1, the rotating sealing door 39 can seal the lower end of the sampling frame 1 as a whole. Therefore, the mixture for stratified sampling inside the sampling frame 1 is in an overall sealed state. At the same time, the abutting plate 34 will always abut against the right surface of the mounting block 29, that is, the sealing effect of the rotating sealing door 39 is good. When the first stratified plate 6 and the second stratified plate subsequently leave the interior of the sampling frame 1, that is, the abutting plate 34 will slowly move away from the right side of the mounting block 29. Since the spring body 40 is installed inside the telescopic cylinder 31, due to the elasticity of the spring body 40, when the abutting plate 34 moves away from the mounting block 29, at this time, the abutting block 28 will move to the right following the telescopic column 30. Thus, the rotating sealing door 39 can be automatically opened to process the mixture after stratified sampling inside the sampling frame 1. This setting can be synchronized when sealing the mixture inside the sampling frame 1 in layers, avoiding the change in the position of the stratified mixture from affecting the subsequent test results, and the sealing is relatively stable. At the same time, the mixture can be quickly discharged for processing under the unsealed state;

[0034] Installation frame 8 is installed on one side of the surface of the sampling frame 1. A driving motor 7 is fixedly connected to the inner side wall of the installation frame 8. The output end of the driving motor 7 is equipped with a lead screw body 9. The lead screw body 9 is inserted and installed inside the moving plate 10. A bevel gear assembly 12 and a limit ring 11 are successively installed on the outer surface of the lead screw body 9 from left to right. A limit rod 13 is inserted and installed inside the moving plate 10. The limit rod 13 is installed on the inner wall of the installation frame 8. Adaptation slots 14 are provided on both the upper and lower surfaces of the installation frame 8. The adaptation slots 14 are adapted to the moving plate 10. A first bevel gear column 15 and a second bevel gear column 16 are successively installed on the front and back surfaces of the bevel gear assembly 12. Both the first bevel gear column 15 and the second bevel gear column 16 are inserted and installed inside the installation frame 8. A connecting bevel gear column 17 is meshed and connected to the outer surface of the second bevel gear column 16. A worm 18 is fixedly connected to the left side surface of the connecting bevel gear column 17. An installation rod 19 is installed on the left side of the worm 18. A discharge tube 37 is installed on the left side of the sampling frame 1. The discharge tube 37 is in a sealed state. When detecting, the discharge tube 37 is opened for sampling detection. There are three groups of discharge tubes 37. When conducting stratified sampling, first lift the connecting frame 2 as a whole, then turn open the rotating sealing door 39, then place the sampling frame 1 as a whole on the mixture on the surface of the trolley. Then when the mixture enters the inside of the sampling frame 1, at this time the sampling frame 1 is divided into three parts, namely the upper, middle, and lower parts, so as to be able to sample the mixture in layers. When the mixture is distributed inside the sampling frame 1, at this time start the driving motor 7, drive the lead screw body 9 to rotate through the driving motor 7. Then when the lead screw body 9 rotates, the moving plate 10 will move to the left on the surface of the lead screw body 9. Thus, the moving plate 10 will drive the first stratified plate 6 inside the first installation frame 4 to move towards the sealing slot 3. Then the first stratified plate 6 will enter the inside of the sealing slot 3 to conduct a stratified sealing operation on the upper and middle mixtures of the sampling frame 1. At the same time, when the moving plate 10 is moving, it can also drive the second stratified plate inside the second installation frame 5 to move. Thus, the second stratified plate will enter the inside of the sampling frame 1 to conduct a stratified sealing operation on the middle and lower mixtures. Through the setting of the limit ring 11, the movement track of the moving plate 10 can be limited. Thus, when the first stratified plate 6 and the second stratified plate enter the inside of the sampling frame 1 as a whole, at this time the left side of the moving plate 10 will abut against the right side surface of the limit ring 11. At the same time, when the lead screw body 9 is in a rotating state, at this time it will drive the bevel gear assembly 12 to rotate. Then the bevel gear assembly 12 will drive the first bevel gear column 15 and the second bevel gear column 16 to rotate. Subsequently, through the meshing of the second bevel gear column 16 and the connecting bevel gear column 17, the connecting bevel gear column 17 can be driven to rotate. Then the connecting bevel gear column 17 will drive the worm 18 to rotate. Then the worm 18 will drive the worm gear 25 to rotate. When the worm gear 25 rotates, the whole rotating shaft 22 can be driven to rotate. Subsequently, the rotating shaft 22 will drive the installation cylinder 23 and the knocking block 24 to rotate. When the knocking block 24 rotates, it will abut against the back surface of the sampling frame 1.Moreover, there are six groups of knocking blocks 24, which can evenly knock the mixed materials after being stratified into upper, middle and lower layers of the sampling frame 1, avoid the loose distribution of the mixed materials, and can compact the mixed materials during the stratified sampling process, facilitating the subsequent detection to conduct stratified detection on the stratified mixed materials as a whole, improving the detection results. Similarly, the second operation frame 36 can also complete the same operation. This setting can, on the one hand, conduct upper, middle and lower stratified sampling of the mixed materials when the mixed materials enter the inside of the sampling frame 1, and at the same time, can seal the upper, middle and lower mixed materials to prevent the mixed materials from flowing. And during the sealing process, in cooperation with the rotation and knocking of the knocking block 24, the mixed materials in the stratification are compacted, enabling the mixed materials to move downward under the action of gravity, solving the problem of loose mixed materials during previous sampling;

[0035] The connecting bevel gear column 17 is installed inside the protective housing 21, and the connecting bevel gear column 17 passes through the inside of the first operation frame 20 and is installed with the worm 18. The protective housing 21 can protect the connecting bevel gear column 17 as a whole. And the bevel gear assembly 12 is composed of three mutually meshing bevel gears. The ends of the first bevel gear column 15 and the second bevel gear column 16 far from the bevel gear assembly 12 are both installed inside the protective housing 21, and the overall fixing effect is good. Moreover, the bottom surface on the left side of the first stratification plate 6 is inclined, so that when the first stratification plate 6 abuts against the inner wall of the sampling frame 1, it will not entrap the mixed materials, and thus the overall sealing effect is good. And when the whole mixed materials enter the sampling frame 1 and are divided into upper, middle and lower layers, the first stratification plate 6, the second stratification plate and the rotating sealing door 39 can operate synchronously to seal the upper, middle and lower layers of mixed materials synchronously, and then take out the mixed materials inside the discharge cylinder 37 for sampling and detection.

[0036] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. When conducting layered sampling, first lift the entire connecting frame 2, then turn open the rotating sealing door 39, and then place the entire sampling frame 1 on the mixture on the surface of the trolley. When the mixture enters the inside of the sampling frame 1, at this time, the sampling frame 1 is divided into three parts, namely the upper, middle, and lower parts, so that the mixture can be sampled in layers. When the mixture is distributed inside the sampling frame 1, start the drive motor 7 at this time. The drive motor 7 drives the screw rod body 9 to rotate. Then, when the screw rod body 9 rotates, the moving plate 10 will move to the left on the surface of the screw rod body 9. Thus, the moving plate 10 will drive the first layered plate 6 inside the first mounting frame 4 to move towards the sealing slot 3. Then, the first layered plate 6 will enter the inside of the sealing slot 3 to perform a layered sealing operation on the upper and middle mixtures in the sampling frame 1. At the same time, when the moving plate 10 is moving, it can also drive the second layered plate inside the second mounting frame 5 to move. Thus, the second layered plate will enter the inside of the sampling frame 1 to perform a layered sealing operation on the middle and lower mixtures. Through the setting of the limiting ring 11, the movement track of the moving plate 10 can be limited. Thus, when the first layered plate 6 and the second layered plate enter the inside of the sampling frame 1 as a whole, at this time, the left side of the moving plate 10 will abut against the right surface of the limiting ring 11. At the same time, when the screw rod body 9 is in a rotating state, it will drive the bevel gear assembly 12 to rotate at this time. Then, the bevel gear assembly 12 will drive the first bevel gear column 15 and the second bevel gear column 16 to rotate. Subsequently, through the meshing of the second bevel gear column 16 and the connecting bevel gear column 17, the connecting bevel gear column 17 can be driven to rotate. Then, the connecting bevel gear column 17 will drive the worm 18 to rotate. Then, the worm 18 will drive the worm gear 25 to rotate. During the rotation of the worm gear 25, the entire rotating shaft 22 can be driven to rotate. Subsequently, the rotating shaft 22 will drive the mounting cylinder 23 and the knocking block 24 to rotate. When the knocking block 24 rotates, it will abut against the back of the sampling frame 1, and there are six groups of knocking blocks 24, which can evenly knock the mixtures after being layered in the upper, middle, and lower parts of the sampling frame 1;

[0037] When the second layered plate inside the second mounting frame 5 moves towards the inside of the sampling frame 1, at this time, the second layered plate will drive the connecting plate 32 to move through the sliding slot 26 at the lower end of the second mounting frame 5. Then, the connecting plate 32, the positioning plate 33, and the abutting plate 34 will move to the left following the abutting plate 34. Then, when the abutting plate 34 abuts against the right surface of the mounting block 29, it can drive the mounting block 29 to move to the left. Then, the mounting block 29 will drive the abutting block 28 to move. At this time, the position of the abutting block 28 is limited by the positioning frame 27, and at this time, the rotating sealing door 39 is in Figure 1The state of the rotating sealing door 39 is formed when the resistance block 28 continues to move, and then when the resistance block 28 continues to move, the resistance block 28 can resist the right side surface of the rotating sealing door 39, and then the resistance block 28 can drive the rotating sealing door 39 to rotate, and then the rotating sealing door 39 will follow the movement of the resistance block 28 and slowly fit the lower surface of the sampling frame 1 until the resistance block 28 stably resists the rotating sealing door 39 to the lower surface of the sampling frame 1, so that when the first layer plate 6 and the second layer plate enter the interior of the sampling frame 1, the rotating sealing door 39 can seal the lower end of the sampling frame 1 as a whole, so that the mixed material sampled in layers inside the sampling frame 1 is in an overall sealed state, and at the same time, the resistance block 28 can prevent the mixed material sampled in layers from being leaking. The touch plate 34 will always contact the right side surface of the mounting block 29, that is, the sealing effect of the rotating sealing door 39 is good. When the first stratified plate 6 and the second stratified plate are separated from the interior of the sampling frame 1, the contact plate 34 will slowly move away from the right side of the mounting block 29. Since a spring body 40 is installed inside the telescopic cylinder 31, through the elasticity of the spring body 40, when the contact plate 34 is away from the mounting block 29, the contact block 28 will follow the telescopic column 30 to move to the right, so that the rotating sealing door 39 can be automatically opened to process the mixed material after stratified sampling inside the sampling frame 1, and the mixed material is taken out from the inside of the discharge cylinder 37 for sampling and detection.
