Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically to a drying mechanism for an integrated barite powder grinding machine. Background Technology

[0002] Drying equipment is a key device responsible for removing moisture in industrial material processing. It can effectively reduce material stickiness and ensure smooth subsequent processing. In vertical grinding and milling integrated machines, the drying equipment works in deep collaboration with the grinding and sorting system. With the help of the linkage design of hot air circulation and material flow, the drying operation is completed simultaneously during the grinding process. This simplifies the production process and improves the overall processing efficiency, becoming one of the core supports for the integrated machine to achieve efficient and integrated operation.

[0003] Currently, existing drying equipment suffers from several problems during operation. It relies solely on the unidirectional airflow from the edge of the grinding disc, preventing hot air from penetrating the bottom layer of the material. Furthermore, high-humidity materials tend to agglomerate, and the hot air can only reach the surface of the agglomerates, resulting in incomplete drying and poor drying uniformity of the bottom layer material.

[0004] By combining the above problems, we can see that the drying mechanisms used in existing barite powder grinding machines on the market are difficult to avoid the problems mentioned above at the same time. Even if they can be solved, they require the use of external tools, which makes it impossible to achieve the desired effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 , Figure 2 and Figures 5-10 The present invention provides a technical solution: a drying mechanism for a barite powder grinding machine, including a vertical grinding mill body 1, a deep drying mechanism 2 provided on the outside of the vertical grinding mill body 1, and a guiding mechanism 3 provided inside the vertical grinding mill body 1. The deep drying mechanism 2 includes a deep drying unit 21, which is located on the outside of the vertical mill body 1. The deep drying unit 21 can perform deep drying on the milled powder. The deep drying mechanism 2 also includes an anti-sticking unit 22, which is located inside the vertical mill body 1. The anti-sticking unit 22 can prevent the wet powder from sticking to the milling equipment. The guiding mechanism 3 can guide the powder to rotate and collide inside the vertical mill body 1.

[0021] As a further definition of the deep drying mechanism 2 of the present invention, the deep drying unit 21 includes a rotating drum 2105. The outer surface of the rotating drum 2105 is rotatably connected to the inner wall of the vertical mill body 1. A grinding disc 2108 is fixedly connected to the top of the rotating drum 2105. The upper surface of the grinding disc 2108 is provided with several identical conical micro-holes 2125 and several identical circular holes 2127. Several identical discharge ports 2126 are provided on the outer surface of the grinding disc 2108. A circular ring 2118 is fixedly connected to the outer surface of the vertical mill body 1. A first sealing bearing 2120 is fixedly connected to the inner wall of the circular ring 2118. The outer surface of the rotating drum 2105 is rotatably connected to the inner ring of the first sealing bearing 2120. Several identical air inlets 2119 are provided on the outer surface of the rotating drum 2105. A heating box 2101 is fixedly connected to one side of the vertical mill body 1. Several identical heating wires 2124 are fixedly connected to the inner wall of the heating box 2101. A mounting base 2123 is fixedly connected to the upper surface of the vertical mill body 1. An air pump 2121 is fixedly connected to the upper surface of the mounting base 2123. An air extraction pipe 2122 is fixedly connected to the input end of the air pump 2121. One end of the air extraction pipe 2122 is fixedly connected to the back of the heating box 2101. The output end of the air pump 2121 is fixedly connected to a multi-directional air outlet pipe 2109. Two ends of the multi-directional air outlet pipe 2109 pass through the vertical mill body 1 and extend into the interior of the vertical mill body 1. One end of the multi-directional air outlet pipe 2109 is fixedly connected to the outer surface of the circular ring 2118. Two grinding rollers 2112 are arranged inside the vertical mill body 1. A connecting pipe 2113 is fixedly connected to the inner wall of each grinding roller 2112. By setting a deep drying unit 21, the deep drying unit 21 can dry the powder from the top and bottom when the powder is just ground, which greatly accelerates the drying efficiency of the powder and reduces the problem of poor powder drying effect.

[0022] Please see Figure 6 Two mounting blocks 2106 are fixedly connected to the outer surface of the vertical grinding mill body 1. Each mounting block 2106 has a first fixing plate 2110 and a second fixing plate 2111 fixedly connected to its outer surface. Each first fixing plate 2110 has a first stepper motor 2117 fixedly connected to its inner wall. Each first stepper motor 2117 has a short shaft 2116 fixedly connected to its output end. The outer surface of each short shaft 2116 is rotatably connected to the inner wall of the mounting block 2106. By setting the first fixing plate 2110 and the second fixing plate 2111, the first fixing plate 2110 can provide a mounting position for the first stepper motor 2117, making the first stepper motor 2117 work more stably. The operation of the first stepper motor 2117 can drive the short shaft 2116 to rotate, providing power for its rotation.

[0023] Please see Figure 7Each short shaft 2116 has a first transmission gear 2115 fixedly connected to its outer surface, and each connecting pipe 2113 has a second transmission gear 2114 fixedly connected to its outer surface. The teeth of each first transmission gear 2115 mesh with the teeth of the second transmission gear 2114. The inner wall of each second fixed plate 2111 is fixedly connected to the outer surface of the multi-directional air outlet pipe 2109. By setting the first transmission gear 2115 and the second transmission gear 2114, the meshing relationship between the two sets can drive the connecting pipe 2113 to rotate, which can further drive the grinding roller 2112 to rotate.

[0024] Please see Figure 5 A drive motor 2104 is fixedly connected to the outer surface of the vertical grinding mill body 1. The output end of the drive motor 2104 is fixedly connected to the bottom end of the rotating drum 2105. By setting the drive motor 2104, the rotating drum 2105 can be driven to rotate.

[0025] Please see Figure 2 The outer surface of the vertical mill body 1 is provided with a rectangular opening 2107. The inner wall of each connecting pipe 2113 is rotatably connected to the outer surface of the multi-directional air outlet pipe 2109. The inner wall of the vertical mill body 1 is fixedly connected with a feed pipe 2102 and a separator 2103. Hot air can be delivered into the interior of the vertical mill body 1 through the rectangular opening 2107. Barite can enter the interior of the vertical mill body 1 through the feed pipe 2102, and the separator 2103 can separate and extract the ground powder.

[0026] The specific implementation of this embodiment is as follows: When this equipment is needed, barite enters the interior of the vertical grinding mill body 1 through the feed pipe 2102 and finally falls onto the grinding disc 2108. At this time, the grinding disc 2108 and the rotating drum 2105 will rotate under the action of the drive motor 2104. Therefore, the centrifugal force generated can cause the barite to move towards the edge of the grinding disc 2108. While the grinding disc 2108 is rotating, the grinding roller 2112 is also driven by the first stepper motor 2117, the first transmission gear 2115, and the second transmission gear 2114. Under the action of the grinding rollers 2112 and 2108, the barite is crushed and pulverized by the interaction of the rollers 2112 and the grinding disc 2108. During this process, the air pump 2121 extracts the hot air from the heating chamber 2101 through the air extraction pipe 2122, and finally delivers it to the inside of the rotating drum 2105 and the grinding rollers 2112 through the multi-way air outlet pipe 2109. Since both the surface of the grinding disc 2108 and the surface of the grinding rollers 2112 are provided with conical micro-holes 2125, the hot air inside the rotating drum 2105 and the grinding rollers 2112 will be discharged through the conical micro-holes 2125. The barite powder is dried from both above and below the surface of the freshly ground barite. Furthermore, the smaller opening of the conical micro-orifice 2125 near the barite powder, combined with the airflow generated during hot air transport, effectively prevents barite powder from entering the grinding disc 2108 and grinding roller 2112 through the conical micro-orifice 2125. This achieves the goal of drying the freshly ground barite powder from both above and below. As the grinding disc 2108 continues to rotate, the barite powder moves through the discharge port 2126 to the grinding disc 210. At the edge of position 8, while the equipment is running, the hot air used for blowing material enters the interior of the vertical mill body 1 through the rectangular opening 2107. The hot air will gather in the space between the rotating drum 2105 and the vertical mill body 1. Therefore, the hot air can only enter the interior of the vertical mill body 1 through the circular hole 2127, so it can blow the barite powder to move upwards of the vertical mill body 1. The qualified barite powder will be screened out by the separator 2103 and conveyed out, thus completing the grinding of barite powder.

[0027] Example 2: Please refer to Figure 5 and Figure 6 The present invention provides a technical solution: a drying mechanism for a barite powder grinding machine. The present invention makes corresponding improvements to address the technical problems mentioned in the background art.

[0028] As a further definition of the deep drying mechanism 2 of the present invention, the anti-adhesion unit 22 includes two mounting plates 2202. A second stepper motor 2203 is fixedly connected to the bottom surface of each mounting plate 2202. A long shaft 2204 is fixedly connected to the output end of each second stepper motor 2203. The outer surface of each long shaft 2204 is rotatably connected to the inner wall of the second fixed plate 2111 and the mounting block 2106. A flip plate 2205 is fixedly connected to the surface of each long shaft 2204. One side of each mounting block 2106 is fixedly connected to... There is a scraper 2201, and the outer surface of each long shaft 2204 is rotatably connected to the inner wall of the scraper 2201. The outer surface of each scraper 2201 is in contact with the outer surface of the grinding roller 2112. Each flipping plate 2205 is set in the inner cavity of the scraper 2201, and the outer surface of each flipping plate 2205 is in contact with the outer surface of the grinding roller 2112. By setting the anti-sticking unit 22, the powder can be prevented from sticking to the grinding roller 2112, and the powder on the grinding roller 2112 can fall into the normal drying step.

[0029] The specific implementation of this embodiment is as follows: When the grinding roller 2112 is working, a small amount of barite powder will adhere to the surface of the grinding roller 2112. When this barite powder passes through the scraper 2201 and the tilting plate 2205, it will be intercepted by the scraper 2201 and the tilting plate 2205. The tilting plate 2205 will rotate according to the rotation cycle preset by the second stepper motor 2203. Therefore, the barite powder scraped off will remain on the scraper 2201 throughout the operating cycle of the second stepper motor 2203. In the space between the grinding roller 2112 and the tilting plate 2205, the barite powder can be continuously supplied with hot air from the opening on the surface of the grinding roller 2112, so that the scraped barite powder can be dried separately. When the second stepper motor 2203 completes its second cycle, it will drive the tilting plate 2205 to rotate 180 degrees through the long shaft 2204, thereby pouring out the barite powder and letting it fall back onto the grinding disc 2108. This achieves both scraping and drying of the scraped barite powder.

[0030] Example 3: Please refer to Figures 2-4 The present invention provides a technical solution: a drying mechanism for a barite powder grinding machine. The present invention makes corresponding improvements to address the technical problems mentioned in the background art.

[0031] As a further definition of the guiding mechanism 3 of the present invention, the guiding mechanism 3 includes a mounting bearing 311, and a rotating cylinder 301 is fixedly connected to the inner ring of the mounting bearing 311. The inner wall of the rotating cylinder 301 has several identical spiral stripes 309, and several identical air guide pipes 310 are fixedly connected to the inner wall of the rotating cylinder 301. Each air guide pipe 310 is disposed within the cavity of the spiral stripes 309, and one end of each air guide pipe 310 penetrates the rotating cylinder 301 and extends to the outer side of the rotating cylinder 301. An annular shell 303 is fixedly connected to the inner wall of the vertical mill body 1, and the outer surface of the rotating cylinder 301 is rotatably connected to the inner wall of the annular shell 303. The inner wall of the annular shell 303 is fixedly connected to the second sealing bearing 304, and the outer surface of the rotating cylinder 301 is rotatably connected to the inner ring of the second sealing bearing 304. One end of the multi-directional air outlet pipe 2109 is fixedly connected to the upper surface of the annular shell 303. By setting the guide mechanism 3, the powder can be made to rotate spirally inside the rotating cylinder 301, so that the powder clumps can frequently collide with the rotating cylinder 301, thereby reducing the clumping rate and increasing the drying efficiency. By setting the deep drying unit 21, the anti-sticking unit 22 and the guide mechanism 3, the problem of low powder drying efficiency caused by various reasons during equipment use can be effectively avoided.

[0032] Please see Figure 3 A first gear 302 is fixedly connected to the outer surface of the rotating cylinder 301. The teeth of the first gear 302 mesh with the second gear 308. A third stepper motor 306 is provided on the outer side of the vertical mill body 1. A rotating shaft 307 is fixedly connected to the output end of the third stepper motor 306. The bottom end of the rotating shaft 307 is fixedly connected to the top end of the second gear 308. With the third stepper motor 306, the operation of the third stepper motor 306 can drive the rotating shaft 307 and the second gear 308 to rotate. In conjunction with the meshing relationship between the second gear 308 and the first gear 302, the rotating cylinder 301 can be driven to rotate.

[0033] Please see Figure 3 A connecting plate 305 is fixedly connected to the outer surface of the vertical grinding mill body 1. The outer surface of the third stepper motor 306 is fixedly connected to the inner wall of the connecting plate 305. By setting the connecting plate 305, the third stepper motor 306 can be provided with a stable working position.

[0034] The specific implementation of this embodiment is as follows: After the barite powder is ground, it is blown into the interior of the rotating cylinder 301 by hot air. At this time, the rotating cylinder 301 rotates under the combined action of the first gear 302, the second gear 308, and the third stepper motor 306. One end of the multi-directional air outlet pipe 2109 is connected to the annular shell 303. When the air pump 2121 is running, part of the hot air flow guided by it will enter the interior of the annular shell 303 and accumulate in the space between the annular shell 303 and the rotating cylinder 301. The annular shell 303 and the rotating cylinder 301 are connected by the second sealed bearing 304, which can ensure that the hot air does not... The hot air accumulated in the annular shell 303 and the rotating cylinder 301 will overflow outwards and enter the interior of the air guide pipe 310. Finally, it will be transported to the spiral stripe 309 through the air guide pipe 310 to form a spiral airflow. With the rotation of the rotating cylinder 301, the barite powder inside the rotating cylinder 301 can be driven to rotate and move upwards. The opening in the middle of the rotating cylinder 301 is a cone shape that is narrow at the top and wide at the bottom. Therefore, the barite powder can rotate and collide back and forth inside the rotating cylinder 301, reducing the probability of barite powder clumping. This can further increase the drying efficiency of barite powder.
