Description

Technical Field

[0001] The present invention relates to the technical field of raw materials for superhard materials, and particularly relates to a pyrophyllite automatic mixing system and a method for using the same. Background Art

[0002] In the process of industrial diamond production, pyrophyllite is required as a pressure transmission, sealing, insulation, and heat preservation medium under high temperature and high pressure. When mixing pyrophyllite materials, the raw materials need to be processed through processes such as feeding, weighing, mixing, and screening. However, the current mixing method used for mixing pyrophyllite in the production process is not continuous between each process, and the turnover volume is large, resulting in waste of raw materials and potential safety hazards during the turnover process. At the same time, each process is independent and not sealed, resulting in a large amount of dust generated during the turnover process, seriously polluting the workshop environment. Therefore, a new type of automatic mixing device is needed that can continuously turnover between each process and prevent excessive dust generation during the turnover process.

[0003] In the Chinese published patent CN108854805A, "A Method and System for Mixing Raw Materials in the Superhard Material Industry", although it effectively improves the workshop environment, strengthens the mutual connection between each process, and the entire mixing process is fully automated, during the conveying process of the material, a Roots blower and a sealed pipeline are used for conveying. However, under the action of the blower, the material collides with the pipeline wall multiple times in the pipeline, resulting in the problem of raw material breakage. At the same time, the breakage rate is as high as 20%, greatly increasing the production cost. At the same time, the overall efficiency of the device is low. Therefore, a method is needed to ensure the generation of dust during the entire mixing process while reducing the breakage rate of raw materials during the material transportation process. Summary of the Invention

And the new automatic mixing device is continuously sealed between each process during the conveying process, effectively improving the workshop environment, and the entire mixing process is fully automated, reducing the labor cost. The raw materials are not broken during the conveying process, meeting the requirements of the production process, and reducing the production cost.

[0029] The drawings are only for illustrative purposes and should not be construed as a limitation of this patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well - known structures and their descriptions in the drawings may be omitted. Detailed Embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0031] Such as Figure 1As shown in the figure, this embodiment discloses an automated pyrophyllite mixing system, which includes an unpacking station 1 and a suspension vibrating screen 2. The suspension vibrating screen 2 is arranged inside the unpacking station 1. The discharge port of the suspension vibrating screen 2 is connected to the feed port of the first belt conveyor 3. The output end of the first belt conveyor 3 is connected to the bottom starting end of the first elevator 4, so that the raw materials enter the first elevator 4 from the suspension vibrating screen 2 via the first belt conveyor 3. The lifting top end of the first elevator 4 is connected to the feed port of the first storage bin 5. A screw conveyor 6 is arranged at the discharge port of the first storage bin 5, and the discharge port of the screw conveyor 6 is connected to the feed port of the batching scale bin 7. The raw materials that enter the first storage bin 5 through the first elevator 4 then enter the batching scale bin 7 via the screw conveyor 6 and are proportioned according to the mixing formula. The discharge port of the batching scale bin 7 is connected to the feed port of the buffer bin 8. At the same time, the discharge port of the buffer bin 8 is connected to the feed port of the second belt conveyor 9. The materials prepared in the batching scale bin 7 enter the second belt conveyor 9 via the buffer bin 8. The buffer bin 8 can play a good buffering role in the process of discharging the materials prepared in the batching scale bin 7, preventing the materials from being damaged during transportation. The discharge port of the second belt conveyor 9 is connected to the bottom starting end of the second elevator 10, and the lifting top end of the second elevator 10 is connected to the feed port of the third belt conveyor 11, so that the materials in the second belt conveyor 9 are lifted into the third belt conveyor 11 via the second elevator 10. The discharge port of the third belt conveyor 11 is connected to the feed port of the second storage bin 12. The discharge port of the second storage bin 12 is connected to the feed port of the mixer 13, so that the materials in the third conveyor 11 enter the mixer 13 via the second storage bin 12. The discharge port of the mixer 13 is connected to the feed port of the disk feeder 14. At the same time, the discharge port of the disk feeder 14 is connected to the feed port of the linear vibrating screen 15. The materials mixed in the mixer 13 enter the linear vibrating screen 15 via the disk feeder 14 for screening and then are discharged.

[0032] As Figure 1 shown in the figure, in this embodiment, the first belt conveyor 3, the second belt conveyor 9 and the third belt conveyor 11 all adopt sealed belt conveyors, so that there is no additional dust overflow during the whole conveying process, no dust pollution will be caused, the environment of the workshop is greatly improved, and at the same time, it can also be other stable sealed transportation mechanisms.

[0033] As Figure 1As shown in the figure, the batching scale bin 7 can weigh the weight of the materials entering the bin body, which is convenient for the staff to adjust according to different formulas. The raw materials enter the batching scale bin 7 through the first storage bin 5 for preparation. After the preparation is completed, the raw materials enter the interior of the second belt conveyor 9 through the buffer bin 8, which generally slows down the falling speed of the raw materials after the preparation is completed. At the same time, the first storage bin 5 stops feeding when the raw materials in the batching scale bin 7 reach the formula ratio. It doesn't start the next round of preparation until all the prepared materials in the batching scale bin 7 have fallen into the second belt conveyor 9 through the buffer bin 8.

[0034] As Figure 1 shown, the materials in the second storage bin 12 are fed into the interior of the mixer 13 according to the workload of the mixer 13. At the same time, an adhesive needs to be added to the mixer 13 for mixing the materials entering the mixer 13. Under the action of the adhesive and the mixer 13, the materials inside the mixer 13 are gradually mixed together. Then, the mixed materials are slowly scattered and evenly transported to the linear vibrating screen 15 by the disk feeder 14 below the mixer 13 to complete the discharging. At the same time, the second storage bin 12 stops feeding the mixer 13 when the materials in the mixer 13 reach the normal workload, and starts feeding the mixer 13 again after all the materials in the mixer 13 have entered the disk feeder 14.

[0035] As Figure 1 shown, this embodiment discloses a pyrophyllite automatic mixing system, which includes two sets of mixing production lines. In this embodiment, the number of the first storage bins 5 in the mixing production line on the left side of the figure is four. Among them, two storage bins contain pyrophyllite large materials with a particle size of 12 - 18 mesh, and the other two storage bins contain pyrophyllite medium materials with a particle size of 18 - 36 mesh. The materials in the first storage bins 5 in the left mixing production line sequentially pass through the screw conveyor 6, the batching scale bin 7, the buffer bin 8, the second belt conveyor 9, the second elevator 10, and the third belt conveyor 11 and enter the second storage bin 12. In this embodiment, the number of the second storage bins 12 in the left mixing production line is two, which are used for temporarily storing the materials prepared according to the formula in the previous process section;

[0036] At the same time, in this embodiment, there is another set of mixing production line on the right side of the figure. The number of the first storage bins 5 in the right mixing production line is two, and the first storage bins 5 contain pyrophyllite fine materials with a particle size of more than 36 mesh. They also enter the second storage bin 12 in the right mixing production line after the batching and conveying processes. In this embodiment, the number of the second storage bins 12 in the right mixing production line is two.

[0037] In this embodiment, the setting of the quantities of the first storage bin 5 and the second storage bin 12 is only a specific configuration made according to a pyrophyllite mixture formula. In specific production and life, according to different pyrophyllite mixture formulas, specific adaptive configurations of the quantities of the first storage bin 5 and the second storage bin 12 are carried out to meet different arrangements in various production processes.

[0038] When the present invention is in use, it includes the following steps:

[0039] Step A: Transport the required pyrophyllite raw materials to the unpacking station. The raw materials are initially screened by a suspension vibrating screen in the unpacking station and then enter the first belt conveyor, and are transported to the first elevator by the first belt conveyor mechanism. The pyrophyllite raw materials are lifted to the first storage bin by the first elevator and put into the first storage bin.

[0040] Step B: The pyrophyllite raw materials in the first storage bin enter the batching scale bin through a screw conveyor, and the required raw materials are weighed according to the formula in the batching scale bin.

[0041] Step C: The materials prepared according to the formula are discharged from the buffer bin below the batching scale bin onto the second belt conveyor, transported to the second elevator by the second belt conveyor, and lifted to the third belt conveyor by the second elevator, and then transported into the second storage bin by the third belt conveyor.

[0042] Step D: The materials prepared according to the formula enter the mixer through the second storage bin, and an adhesive is added to the mixer to mix the materials inside the mixer.

[0043] Step E: The materials mixed in the mixer are discharged into the disk feeder and evenly transported to the linear vibrating screen by the disk feeder. The well-mixed materials are screened by the linear vibrating screen to complete the discharging.

[0044] After using this system for pyrophyllite mixing work, the pyrophyllite raw materials below 6 mesh are sent to the unpacking station 1. Turn on the power of the unpacking station 1. The raw materials are transported from the unpacking station 1 to the first elevator 4 through the suspension vibrating screen 2 and the first belt conveyor 3, and then lifted to the first storage bin 5 by the first elevator 4. 10 tons of raw materials can be transported per hour, and are transported to the batching scale bin 7 for weighing and batching through the screw conveyor 6. 8 tons of raw materials can be configured per hour. The materials prepared according to the formula requirements are discharged into the buffer bin 8, and the materials in the buffer bin 8 are discharged from the lower discharge port onto the second belt conveyor 9 and transported to the second elevator 10. After lifting, they are transported to the second storage bin 12 above the mixer 13 by the third belt conveyor 11. When there is no material in the mixer 13, the materials in the second storage bin 2 are discharged into the mixer 13 to mix the raw materials. 6 tons of raw materials can be mixed per hour, meeting the production process requirements and greatly increasing the production efficiency.
