Description

Technical Field

[0001] This utility model belongs to the field of barium sulfate powder technology, specifically a modifier addition mechanism for barium sulfate powder production. Background Technology

[0002] In the production of barium sulfate powder, surface treatment with modifiers is typically required to improve its surface activity, dispersibility, and compatibility with other materials. The effect of the modifier directly affects the final properties of the barium sulfate powder, such as its performance in applications in plastics, coatings, and rubber. However, current modifier addition methods still have many problems in practical applications, limiting further improvements in the quality of barium sulfate powder products.

[0003] Currently, common modifier addition methods mostly employ silo storage, gravity, or screw conveying. For solid modifiers, such as calcium stearate and polyethylene wax, clumping is prone to occur during storage due to moisture or pressure. Clumped modifiers not only have difficulty passing through conveying pipes but also lead to uneven feeding, affecting the mixing effect with barium sulfate powder and thus reducing the modified quality of the powder.

[0004] Therefore, this utility model provides a modifier addition mechanism for the production of barium sulfate powder. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a modifier addition mechanism for barium sulfate powder production is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A modifier addition mechanism for barium sulfate powder production, as described in this utility model, includes a base plate; a storage tank is fixedly installed on the top of the base plate, a top cover plate is movably installed on the top of the storage tank, and an addition port is fixedly installed on one side of the bottom of the storage tank; a dispensing mechanism is provided at the bottom of the inner wall of the storage tank, and a feeding mechanism is provided on the inner wall of the storage tank; a driving mechanism is provided at the top of the rotating cylinder, and a stirring component is provided on the surface of the driving mechanism; a scraping component is provided on the inner wall of the storage tank, and a one-way transmission mechanism is provided on the inner wall of the storage tank. The material dispensing mechanism includes a rotating cylinder, dispensing plates, and a fixed circular plate. The rotating cylinder is rotatably installed at the bottom of the inner wall of the storage tank. Several sets of dispensing plates are arranged in a ring and fixedly installed on the surface of the rotating cylinder. The fixed circular plate is fixedly installed on the bottom of the inner wall of the storage tank near the rotating cylinder. The fixed circular plate is rotatably installed with the rotating cylinder. The cooperation between the rotating cylinder and the dispensing plates can form multiple compartments, allowing materials to fall into the compartments, thereby achieving the purpose of quantitative material dispensing. The fixed circular plate can prevent materials from falling downwards and prevent materials from filling the compartments of the dispensing plate.

[0007] Preferably, the feeding mechanism includes a rotating disk, a small feeding hole, and a large feeding hole. The rotating disk is rotatably mounted on the top of the fixed circular plate. The small feeding hole is located on one side of the rotating disk surface, and the large feeding hole is located on one side of the fixed circular plate surface. In this design, the rotating disk and the small feeding hole work together to transport the material inside the storage tank to the compartment of the distribution plate through the small feeding hole and the large feeding hole. At the same time, the rotating disk can also seal the large feeding hole by rotating, preventing the material from falling downwards.

[0008] Preferably, the drive mechanism includes a connecting plate, a rotating shaft, and a servo motor. The connecting plate is threaded onto the top of the rotating cylinder, and the top of the connecting plate is fixedly installed with the rotating shaft. The servo motor is fixedly installed on the top of the upper cover plate, and the output end of the servo motor is movably connected to the rotating shaft. In this scheme, the combined use of the connecting plate, rotating shaft, and servo motor can provide the main power output for the entire device. At the same time, the separate design of the servo motor and the rotating shaft makes it more convenient for users to clean the storage tank.

[0009] Preferably, the stirring assembly includes stirring blades and through holes. Several sets of stirring blades are arranged in a ring and fixedly mounted on the surface of the rotating shaft. The surface of the stirring blades is provided with through holes. In this scheme, the stirring blades can rotate and continuously stir the modifier inside the storage tank by being driven by the rotating shaft, so that the lumps in the modifier can be broken up. The opening of the through holes can enhance the stirring efficiency of the stirring blades and can make the modifier pulverized when passing through the through holes.

[0010] Preferably, the scraping assembly includes an L-shaped support rod and a scraper. Four sets of L-shaped support rods are provided, and the four sets of L-shaped support rods are fixedly installed in a ring at the bottom of the rotating shaft surface. The side of the L-shaped support rod away from the rotating shaft is fixedly installed with the scraper, and the scraper is slidably installed with the rotating disk. In this solution, the cooperation between the L-shaped support rod and the scraper can continuously scrape the material on the surface of the rotating disk through the drive of the rotating shaft, so that the material will not adhere to its surface, and at the same time, it can facilitate the material to fall downwards.

[0011] Preferably, the unidirectional transmission mechanism includes a rotating block, a small rotating plate, a torsion spring, an outer ring, a connecting long plate, and a conical block. The rotating block is fixedly installed on the surface of the rotating shaft near the rotating disk. The small rotating plate is rotatably mounted on the inner wall of the rotating block in a ring shape. The inner wall of the rotating block is fixedly installed with the torsion spring. The connecting long plate is fixedly installed on the top of the rotating disk. The inner wall of the connecting long plate is fixedly installed with the outer ring. The inner wall of the outer ring is fixedly installed with the conical block. The conical block and the small rotating plate slide against each other. In this scheme, the coordinated use of the rotating block, the small rotating plate, the torsion spring, the outer ring, the connecting long plate, and the conical block can drive the rotating disk to rotate by the forward and reverse rotation of the rotating shaft, thereby allowing the user to remotely control the rotation angle of the rotating disk to ensure that the rotating disk can properly unload and seal materials.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The modifier addition mechanism for barium sulfate powder production described in this utility model, through the arrangement of a rotating cylinder, a distributing plate, a fixed circular plate, a rotating disk, a small discharge hole, and a large discharge hole, allows the rotating cylinder and the distributing plate to work together to form multiple compartments, enabling materials to fall into the compartments and thus achieving quantitative feeding. The fixed circular plate can prevent materials from falling downwards and filling the compartments of the distributing plate. The rotating disk and the small discharge hole can transport materials from inside the storage tank to the compartments of the distributing plate through the small discharge hole and the large discharge hole. At the same time, the rotating disk can also seal the large discharge hole by rotating, preventing materials from falling downwards.

[0014] 2. The modifier addition mechanism for barium sulfate powder production described in this utility model, through the arrangement of a connecting plate, a rotating shaft, a servo motor, a stirring blade, and a through hole, enables the coordinated use of the connecting plate, rotating shaft, and servo motor to provide the main power output for the entire equipment. At the same time, the separate design of the servo motor and the rotating shaft makes it more convenient for users to clean the storage tank. The stirring blade can rotate and continuously stir the modifier inside the storage tank through the drive of the rotating shaft, so that the lumps in the modifier can be broken up. The opening of the through hole can enhance the stirring efficiency of the stirring blade, so that the modifier can be crushed when passing through the through hole. Attached Figure Description

The rotating cylinder 51 is rotatably installed at the bottom of the inner wall of the storage tank 2. Several sets of distribution plates 52 are provided, and these distribution plates 52 are fixedly installed in a ring on the surface of the rotating cylinder 51. A fixed circular plate 53 is fixedly installed on the bottom of the inner wall of the storage tank 2 near the rotating cylinder 51, and the fixed circular plate 53 is rotatably installed with the rotating cylinder 51. The feeding mechanism 6 includes a rotating disk 61, a small feeding hole 62, and a large feeding hole 63. The rotating disk 61 is rotatably installed on the top of the fixed circular plate 53. The small feeding hole 62 is located on one side of the surface of the rotating disk 61, and the large feeding hole 63 is located on one side of the surface of the fixed circular plate 53. The drive mechanism 7 includes a connecting plate 71, a rotating shaft 72, and a servo motor 73. The connecting plate 71 is threaded. The top of the rotating cylinder 51 is installed on the top of the connecting plate 71, which is fixedly installed on the top of the rotating shaft 72. The servo motor 73 is fixedly installed on the top of the upper cover plate 3, and the output end of the servo motor 73 is movably connected to the rotating shaft 72. The stirring assembly 8 includes stirring blades 81 and through holes 82. Several sets of stirring blades 81 are arranged and fixedly installed in a ring on the surface of the rotating shaft 72. Through holes 82 are opened on the surface of the stirring blades 81. The scraping assembly 9 includes L-shaped support rods 91 and scrapers 92. Four sets of L-shaped support rods 91 are arranged and fixedly installed in a ring at the bottom of the surface of the rotating shaft 72. The side of the L-shaped support rods 91 away from the rotating shaft 72 is fixedly installed with the scraper 92. The scraper 92 is slidably mounted on the rotating disk 61. The one-way transmission mechanism 10 includes a rotating block 101, a rotating small plate 102, a torsion spring 103, an outer ring 104, a connecting long plate 105, and a conical block 106. The rotating block 101 is fixedly mounted on the surface of the rotating shaft 72 near the rotating disk 61. The rotating small plate 102 is rotatably mounted on the inner wall of the rotating block 101 in a ring shape. The inner wall of the rotating block 101 is fixedly mounted on the torsion spring 103. The connecting long plate 105 is fixedly mounted on the top of the rotating disk 61. The inner wall of the connecting long plate 105 is fixedly mounted on the outer ring 104. The inner wall of the outer ring 104 is fixedly mounted on the conical block 106. The conical block 106 and the rotating small plate 102 slide against each other.

[0026] like Figures 1 to 5As shown, the combined use of the rotating cylinder 51 and the distribution plate 52 forms multiple compartments, allowing materials to fall into them and achieving quantitative feeding. The fixed circular plate 53 prevents materials from falling downwards and filling the compartments of the distribution plate 52. The combined use of the rotating disk 61 and the small discharge hole 62 allows materials inside the storage tank 2 to be transported to the compartments of the distribution plate 52 through the small discharge hole 62 and the large discharge hole 63. At the same time, the rotating disk 61 can also seal the large discharge hole 63 by rotating, preventing materials from falling downwards. The combined use of the connecting plate 71, the rotating shaft 72, and the servo motor 73 provides the main power output for the entire device. The separate design of the servo motor 73 and the rotating shaft 72 makes it easier for users to clean the storage tank 2. The stirring blade 81 can rotate... The drive of the rotating shaft 72 enables rotation and continuous agitation of the modifier inside the storage tank 2, allowing lumps in the modifier to be dispersed. The opening of the through hole 82 enhances the agitation efficiency of the stirring blade 81, allowing the modifier to be crushed as it passes through the through hole 82. The cooperation between the L-shaped support rod 91 and the scraper 92 allows the rotating shaft 72 to continuously scrape the material on the surface of the rotating disk 61, preventing the material from adhering to its surface and facilitating its downward fall. The cooperation of the rotating block 101, rotating small plate 102, torsion spring 103, outer ring 104, connecting long plate 105, and conical block 106 enables the rotating disk 61 to rotate by the forward and reverse rotation of the rotating shaft 72, allowing the user to remotely control the rotation angle of the rotating disk 61 to ensure that the rotating disk 61 can properly discharge and seal materials.

[0027] Working principle: During operation, first place the base plate 1 on a flat surface. Then, the user opens the top cover 3 and pours the modifier into the storage tank 2. Next, reinstall the top cover 3 on top of the storage tank 2. During installation, ensure the output shaft of the servo motor 73 is properly engaged with the rotating shaft 72. Then, start the servo motor 73 to drive the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will drive the stirring blade 81 to rotate. The rotation of the stirring blade 81 will agitate the modifier inside the storage tank 2, causing it to... The agglomerated modifier is broken up and kept loose. When the rotating shaft 72 rotates, it drives the rotating cylinder 51 to rotate through the connecting plate 71. At the same time, the rotating block 101 also rotates. After the agitation is completed, the servo motor 73 is started to drive the rotating shaft 72 to reverse. When the rotating shaft 72 reverses, it will drive the rotating block 101 to reverse. The reverse rotation of the rotating block 101 will cause the rotating small plate 102 to lock with the conical block 106. At that time, the rotating block 101 will drive the outer ring 104 to rotate. The rotation of the outer ring 104 The rotating disk 61 is driven to rotate via the connecting plate 105. As the rotating disk 61 rotates, the small discharge holes 62 on its surface move accordingly until they reach the large discharge holes 63 and stop. Then, the servo motor 73 is restarted to make it rotate forward, thereby enabling the rotating shaft 72 to drive the L-shaped support rod 91 and the scraper 92 to rotate. When the L-shaped support rod 91 and the scraper 92 rotate, they continuously scrape the material on the surface of the rotating disk 61, and the material falls into the large discharge holes 63 through the small discharge holes 62 and the large discharge holes 63. Inside the compartment of the material distribution plate 52, as the rotating shaft 72 drives the rotating cylinder 51 to rotate continuously, the rotating cylinder 51 will drive the material distribution plate 52 to rotate and transport the material inside to the addition port 4, and then discharge it outward through the addition port 4. When stirring is required, the user needs to start the servo motor 73 to reverse so that the rotating shaft 72 drives the outer ring 104 and the rotating disk 61 to rotate through the rotating block 101, so that the small discharge hole 62 is no longer located below the large discharge hole 63, and the material will not fall downward.
