Description

Technical Field

[0001] This invention relates to the field of roller mill mixing technology, and more particularly to an auxiliary rolling and homogenizing mixing device for refractory raw materials. Background Technology

[0002] Mixing and homogenization is the core process in refractory raw material processing. The uniformity of the composition of refractory raw materials directly determines the key properties of subsequent refractory products, such as molding strength and high temperature resistance. Therefore, it is necessary to use integrated rolling and stirring mixing equipment to refine and homogenize refractory raw materials. At present, the industry commonly uses wheel mill mixing equipment that combines rolling, crushing and stirring functions.

[0003] Currently, in actual operation, the existing roller mixers mainly use the rollers to initially disperse the materials, but their mixing and homogenization functions are insufficient. Due to structural limitations, the materials are prone to stratification, local agglomeration, and bottom adhesion and accumulation within the mixing seat. Conventional scrapers cannot effectively reach the middle area where the rollers travel in the mixing seat, resulting in uneven mixing and inconsistent composition of the materials, which affects the homogenization effect of refractory raw materials and the subsequent molding quality.

[0004] Therefore, it is necessary to design an auxiliary rolling, homogenizing and mixing device for refractory raw materials to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary rolling and homogenizing mixing device for refractory raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A refractory raw material auxiliary rolling and homogenizing mixing device includes a base and a stirring seat fixedly installed on the top surface of the base. A fixed sleeve is fixedly installed on the inner bottom surface of the stirring seat. A rolling and homogenizing mixing structure is provided on the inner side of the stirring seat. The rolling and homogenizing mixing structure includes a drive seat set at the top of the fixed sleeve. A drive motor for driving the drive seat is provided on the bottom surface of the base. Support arms are provided on both sides of the drive seat. Rolling wheels are rotatably installed at the bottom end of the support arms. Turntables are provided on the other two sides of the drive seat. Three stirring cylinders arranged in a circular array are fixedly installed on the bottom surface of the turntables. A vibration component for driving the rolling wheels to vibrate slightly is provided between two of the rolling wheels and the fixed sleeve. A scraping component for scraping off and stirring the material adhering to the inner bottom surface of the stirring seat is provided on the inner side of the stirring cylinder. A discharge plate is provided at the discharge port of the stirring seat.

[0007] As a preferred embodiment of the present invention, the drive seat is fixedly mounted with a bracket at the side of the turntable, and two scraper plates are fixedly mounted at the bottom of the bracket.

[0008] As a preferred embodiment of the present invention, a shovel plate that fits against the outer wall of the roller is fixedly installed on the side of the support arm.

[0009] As a preferred embodiment of the present invention, the vibration assembly includes an inner cavity formed inside the grinding wheel, a flywheel rotatably mounted on the inner wall of the inner cavity, a shaft fixedly connected to the flywheel passing through the side of the grinding wheel, a transmission gear fixedly mounted at the end of the shaft away from the flywheel, a gear ring disk meshing with the transmission gear fitted on the outer wall of the fixed sleeve, a sliding groove formed on the outer wall of the fixed sleeve, a slider slidably connected to the sliding groove fixedly mounted on the inner wall of the gear ring disk, a fixing ring fixedly fitted on the outer wall of the fixed sleeve at a position below the gear ring disk, and a spring fixedly mounted between the top surface of the fixing ring and the gear ring disk.

[0010] As a preferred embodiment of the present invention, the outer wall of the fixing sleeve is fitted with a protective shell for protecting the transmission gear, gear ring, and fixing ring.

[0011] In a preferred embodiment of the present invention, the shaft, flywheel, inner cavity, and grinding wheel are all coaxially arranged, and the spring is in a compressed state.

[0012] As a preferred embodiment of the present invention, the scraping assembly includes a guide port opened at the bottom end of the mixing cylinder, a guide strip slidably installed on the inner wall of the guide port, a connecting plate fixedly installed on the bottom surface of the guide strip, and a scraper fixedly installed on the bottom surface of the connecting plate.

[0013] As a preferred embodiment of the present invention, a transmission wedge is fixedly installed on the top surface of the guide bar, a transmission rod is provided through the top end of the stirring cylinder, a drive wedge adapted to the transmission wedge is fixedly installed at the bottom end of the transmission rod, and a spring is fixedly installed between the side of the transmission wedge and the inner wall of the stirring cylinder.

[0014] As a preferred embodiment of the present invention, the bottom surface of the drive seat is fixedly equipped with a plurality of fixed rods arranged in a circular array and corresponding to the top end of the transmission rod, wherein the bottom end of the fixed rod and the top end of the transmission rod are both circular.

[0015] As a preferred embodiment of the present invention, the scraper is inclined and the bottom surface of the scraper is in contact with the inner bottom surface of the stirring seat.

[0016] The present invention has the following beneficial effects: 1. When the equipment of the present invention is running, the grinding wheel rotates synchronously in a circular motion and rotates on its own axis under the drive seat. It uses its own weight and rotational extrusion force to break up the agglomerated particles of raw materials. The shovel plate scrapes off the material adhering to the surface of the grinding wheel in time to avoid affecting the operation. The bottom shovel plate continuously shovels the raw materials into the grinding wheel track to eliminate grinding dead corners. In addition, the micro-vibration of the vibration component increases the grinding pressure, making the raw materials fine and uniform. This lays the foundation for homogenized raw materials for subsequent thorough mixing and homogenization. The raw material particles after grinding are uniform in size and free of large agglomerates, reducing the mixing resistance and allowing the particles to quickly fuse during the subsequent mixing process, improving the mixing efficiency and homogenization effect. 2. The vibration compensation structure of this invention can compensate for the displacement difference caused by the vibration of the rolling mill through the cooperation of the sliding groove and the slider, ensuring that the transmission gear and the gear ring disk always mesh well, ensuring the continuous and stable operation of the flywheel. The protective shell wraps the core transmission components to prevent refractory material debris from entering, preventing component wear and jamming. At the same time, the circular contact surface between the transmission rod and the fixed rod reduces friction, reduces component wear, extends the service life of the equipment, and ensures the continuous and smooth progress of the processing process. 3. The turntable of this invention drives the mixing drum to rotate, continuously stirring and homogenizing the crushed raw materials, so that the crushed particles are fully integrated. The scraping component, through periodic reciprocating sliding, thoroughly scrapes off the material adhering to the bottom surface of the mixing seat, avoiding material accumulation and clumping. At the same time, the reciprocating movement of the scraper forms a secondary stirring of the material, breaking the stratification state and further improving the uniformity of material mixing, ensuring that the final processed material has consistent composition and uniform texture, meeting the processing quality requirements of refractory raw materials.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes the refractory raw material auxiliary compaction and homogenization mixing device disclosed in this example, referring to... Figure 1-8 The system includes a base 1 and a mixing seat 2 fixedly installed on the top surface of the base 1. A fixing sleeve 3 is fixedly installed on the inner bottom surface of the mixing seat 2. A grinding and homogenizing mixing structure 4 is provided on the inner side of the mixing seat 2. The grinding and homogenizing mixing structure 4 includes a drive seat 42 provided on the top of the fixing sleeve 3. A drive motor 41 for driving the drive seat 42 is provided on the bottom surface of the base 1. Support arms 43 are provided on both sides of the drive seat 42. A grinding wheel 44 is rotatably installed at the bottom end of the support arm 43. Turntables 45 are provided on the other two sides of the drive seat 42. The bottom surface of the turntables 45 is fixedly installed on the bottom surface of the drive seat 42. Three mixing drums 46 arranged in a ring array are fixedly installed. A shovel plate 47 that fits against the outer wall of the grinding wheel 44 is fixedly installed on the side of the support arm 43. A bracket 48 is fixedly installed on the drive seat 42 at the side of the turntable 45. Two scraper plates 49 are fixedly installed at the bottom of the bracket 48. A vibration component 5 for driving the grinding wheel 44 to vibrate slightly is provided between the two grinding wheels 44 and the fixed sleeve 3. A scraping component 6 for scraping off the material adhering to the bottom surface of the mixing seat 2 and for stirring is provided on the inner side of the mixing drum 46. A discharge plate 7 is provided at the discharge port of the mixing seat 2.

[0021] The implementation principle of this embodiment is as follows: When in use, the staff first manually turns on the drive motor 41. After the drive motor 41 starts, it quickly drives the drive base 42 to run stably. Under the transmission action of the drive base 42, the grinding wheel 44 connected to the bottom of the support arm 43 will not only follow the drive base 42 to rotate in a circle, but will also rotate synchronously on its own. At the same time, the two turntables 45 installed on the bottom of the drive base 42 will also rotate synchronously, thereby driving the mixing drum 46 to rotate at a uniform speed. The working principle and connection method of the drive base 42 are all existing mature technologies, and will not be described in detail here. After the drive motor 41 is fully started and reaches a stable operating state, the operator slowly adds the refractory raw material to be processed into the mixing seat 2. During continuous operation, the grinding wheel 44 uses its own weight and the squeezing force generated by rotation to fully crush the added refractory raw material, breaking down and refining the agglomerated particles in the raw material. Meanwhile, the shovel plate 47 installed on the support arm 43 moves in real time with the support arm 43, precisely fitting the surface of the grinding wheel 44, and promptly scraping off the material adhering to its surface during the grinding process, effectively preventing material from adhering to the grinding wheel 44 and affecting its normal rotation. The rotating disc 48 ensures the smooth operation of the crushing process; and the two shovel plates 49 at the bottom of the support 48 will operate synchronously, continuously shoveling the raw material from the bottom of the mixing seat 2 onto the running trajectory of the crushing wheel 44, ensuring that every piece of raw material can be touched and fully crushed by the crushing wheel 44, avoiding crushing dead corners; at the same time, during the continuous operation of the crushing wheel 44, the vibration component 5 can realize the micro-vibration of the crushing wheel 44 and the support arm 43, and the vibration further enhances the crushing force and crushing effect of the crushing wheel 44 on the raw material, making the raw material crushed more evenly and finely; in addition, the rotating disc 48... During the rotation of the mixing drum 46, the material crushed by the roller 44 is continuously stirred and homogenized, so that the crushed raw material particles can be fully integrated and the material can be fully processed. Furthermore, the scraping component 6 installed on the mixing drum 46 can completely scrape off the material adhering to the bottom surface of the mixing seat 2, preventing material accumulation and adhesion, and further ensuring that the material is mixed more thoroughly and evenly, thus guaranteeing the quality of the final processed material. After the material processing is completed, the discharge plate 7 on the mixing seat 2 can be opened, and the material can be discharged through the discharge port.

[0022] Example 2: Based on Example 1, this example discloses an auxiliary rolling and homogenizing mixing device for refractory raw materials, such as... Figure 3-5As shown, the vibration assembly 5 includes an inner cavity 51 formed inside the grinding wheel 44. A flywheel 53 is rotatably mounted on the inner wall of the inner cavity 51. A shaft 52, which is fixedly connected to the flywheel 53, is provided through the side of the grinding wheel 44. The shaft 52, flywheel 53, inner cavity 51, and grinding wheel 44 are all coaxially arranged. A transmission gear 54 is fixedly mounted on the end of the shaft 52 away from the flywheel 53. A gear ring disk 55 that meshes with the transmission gear 54 is fitted on the outer wall of the fixing sleeve 3. A groove 56 is provided on the outer wall of the fixing sleeve 3. A slider 57 that is slidably connected to the groove 56 is fixedly installed on the inner wall of the gear ring disk 55. A fixing ring 58 is fixedly fitted on the outer wall of the fixing sleeve 3 below the gear ring disk 55. A spring 59 is fixedly installed between the top surface of the fixing ring 58 and the gear ring disk 55. The spring 59 is in a compressed state. A protective shell 510 for protecting the transmission gear 54, gear ring disk 55, and fixing ring 58 is fitted on the outer wall of the fixing sleeve 3.

[0023] The implementation principle of this embodiment is as follows: During equipment operation, the support arm 43 and the grinding wheel 44 rotate synchronously with the drive seat 42. During this process, since the fixed sleeve 3 is always fixedly installed on the inner bottom surface of the mixing seat 2, its position remains unchanged. This allows the shaft 52 connected to the grinding wheel 44 to rotate smoothly along the top surface of the gear ring disk 55 as the shaft 52 rotates with the grinding wheel 44. Simultaneously, under the meshing action of the transmission gear 54 and the gear ring disk 55, the transmission gear 54 drives the shaft 52 and the flywheel 53 connected to the shaft 52 to rotate at high speed. The flywheel 53 generates a certain centrifugal force during high-speed rotation, thus continuously vibrating the grinding wheel 44, thereby enhancing the grinding effect of the grinding wheel 44 on the refractory materials. When the grinding wheel 44 and the support arm 43 experience slight vibration under the vibration... During vibration, due to the elastic support of spring 59, the gear ring disk 55 can slide upward along the axial direction of the fixed sleeve 3 through the sliding engagement between the slide groove 56 and the slider 57. This sliding structure can effectively compensate for the displacement difference generated by the vibration of the grinding wheel 44 and the support arm 43, ensuring that the gear ring disk 55 can always maintain a good meshing state with the transmission gear 54, thereby ensuring that the flywheel 53 can run continuously and stably and the vibration effect of the grinding wheel 44 is uninterrupted. In addition, the protective shell 510 connected to the shaft 52 will move synchronously with the movement of the shaft 52, always enclosing the core transmission components such as the transmission gear 54 and the gear ring disk 55, playing an effective protective role. This can prevent refractory material debris from entering the transmission components during the mixing process, prevent the components from wearing, jamming, and other problems, and ensure the normal and stable operation of the equipment.

[0024] Example 3: Based on Example 1, this example discloses an auxiliary rolling and homogenizing mixing device for refractory raw materials, such as... Figure 6-8As shown, the scraping assembly 6 includes a guide port 61 at the bottom of the mixing drum 46. A guide strip 62 is slidably installed on the inner wall of the guide port 61. A connecting plate 63 is fixedly installed on the bottom surface of the guide strip 62. A scraper 64 is fixedly installed on the bottom surface of the connecting plate 63. The scraper 64 is inclined and its bottom surface is in contact with the inner bottom surface of the mixing seat 2. A transmission wedge 65 is fixedly installed on the top surface of the guide strip 62. A transmission rod 66 is passed through the top of the mixing drum 46. A drive wedge 67 adapted to the transmission wedge 65 is fixedly installed at the bottom of the transmission rod 66. A spring 68 is fixedly installed between the side of the transmission wedge 65 and the inner wall of the mixing drum 46. Several fixed rods 69 arranged in a ring array and corresponding to the top of the transmission rod 66 are fixedly installed on the bottom surface of the drive seat 42. The bottom of the fixed rods 69 and the top of the transmission rod 66 are both circular.

[0025] The implementation principle of this embodiment is as follows: When the turntable 45 drives the mixing drum 46 to rotate continuously, the transmission rod 66 at the top of the mixing drum 46 will periodically contact and separate from several fixed rods 69 pre-set on the bottom surface of the drive seat 42 as the mixing drum 46 rotates. Since the top of the transmission rod 66 and the bottom of the fixed rod 69 are both designed with a circular structure, this arc-shaped contact surface can effectively reduce the friction when they contact each other, and at the same time provide a smooth guiding effect for the up and down sliding of the transmission rod 66. This allows the transmission rod 66 to slide smoothly downwards when it contacts the fixed rod 69, and when the transmission rod 66 rotates with the mixing drum 46 until it is completely separated from the fixed rod 69, it can quickly slide upwards to reset. Specifically, when the transmission rod 66 contacts the fixed rod 69 and slides downwards, it will simultaneously drive the drive wedge 67 connected to its bottom to move downwards. The bottom of the drive wedge 67 is provided with an inclined surface. During its downward movement, this inclined surface will interact with the corresponding inclined surface of the transmission wedge 65. With the guidance and force transmission effect of the inclined surface, the transmission... The wedge 65 drives the guide bar 62, connecting plate 63, and scraper 64, which are fixedly connected to it, to slide horizontally along the pre-set guide opening 61 on the mixing seat 2. When the transmission rod 66 rotates with the mixing drum 46 and moves out of the contact range of the fixed rod 69, under the elastic reset action of the second spring 68, the transmission rod 66 slides upward and returns to its initial position, thereby driving the drive wedge 67, transmission wedge 65, guide bar 62, connecting plate 63, and scraper 64 to reset together. This cycle repeats, realizing the periodic reciprocating sliding of the scraper 64. While the scraper 64 is reciprocating, the mixing drum 46 always remains in a rotating state. The two work together, and the scraper 64 can efficiently scrape off the material adhering to the bottom surface of the mixing seat 2, effectively avoiding material accumulation and clumping that would affect the mixing effect. At the same time, the reciprocating movement of the scraper 64 can also form a secondary stirring effect on the material in the mixing drum 46, breaking the stratification of the material and further improving the homogenization and mixing effect of the material, ensuring that the mixed material has a uniform composition and consistent texture.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
