Description

Technical Field

[0001] This invention relates to the technical field of flow control equipment, and in particular to an adaptive flow control compartment without opening operation. Background Technology

[0002] In modern industrial production, especially in mineral resource development, building material manufacturing and chemical industry, material handling and processing is a crucial link. Tube mills, as one of the core equipment for material processing, are widely used to crush, mix and disperse various solid materials. Their basic principle is to use the impact and friction generated by the grinding media loaded in the cylinder during rotation to refine the material to the required particle size.

[0003] Although tube mills play an important role in material processing, the design and operation of traditional tube mills have some inherent limitations. One of the most significant problems is the regulation of material flow within the mill. Traditional tube mill diaphragm devices are usually fixed, which means that once the equipment starts running, the position of the diaphragm plates cannot be changed unless maintenance is performed. This static flow regulation method limits the tube mill's ability to adapt to changes in material characteristics, such as fluctuations in material hardness, moisture, or throughput, which can lead to material blockage and affect the overall efficiency of the mill. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an adaptive flow regulation compartment without opening operation, the specific technical solution of which is as follows:

[0005] An adaptive flow regulating compartment without opening operation is used to automatically regulate the flow rate of materials inside the tube mill;

[0006] The device includes multiple compartment structures installed on a tube mill, which divide the interior of the tube mill into multiple independent compartments. Each compartment structure consists of an outer ring fixed to the tube mill and multiple fan plates located within the outer ring. The outer ring is coaxial with the tube mill, and the multiple fan plates are arranged in a ring. When the plane of the fan plate is perpendicular to the axis of the tube mill, the multiple fan plates are coplanar and block the outer ring. When the plane of the fan plate is relatively inclined to the axis of the tube mill, the gap between two adjacent fan plates is used for material flow. A connecting shaft is provided in the middle of each fan plate, which is arranged radially along the outer ring, and the end of the connecting shaft is rotatably mounted on the outer ring.

[0007] In an improved version of the above implementation, a circular groove is formed on the outer circumference of the outer ring, and multiple elongated holes communicating with the inside of the tube mill are formed in the groove. The multiple elongated holes are arranged in a ring, and the length direction of the elongated holes is parallel to the axis of the tube mill. A movable ring is slidably fitted in the circular groove, and a connecting shaft passes through the elongated holes and the movable ring and is rotatably mounted on the movable ring.

[0008] The moving ring is equipped with a transmission structure. When the moving ring moves along the axis of the tube mill in the circular groove, the transmission structure drives each connecting shaft to rotate.

[0009] In an optimized version of the above implementation, the transmission structure includes a rotating ring rotatably sleeved on a movable ring, a plurality of gears meshing on the rotating ring, and the plurality of gears being respectively mounted on a plurality of connecting shafts;

[0010] The rotating ring is provided with multiple inclined arms that are inclined relative to the axis of the tube mill. The end of the inclined arm away from the rotating ring is provided with a shaft. One end of the shaft slides through the inclined arm, and the other end of the shaft is provided with a connecting wheel that is rotatably mounted on the outer ring.

[0011] In an improved version of the above implementation, the moving ring is provided with multiple spring pieces, each of which is provided with a connecting post, and the connecting post is rotatably mounted on the rotating ring.

[0012] In an improved version of the above implementation, multiple sliders are slidably arranged on the rotating ring, the connecting column is rotatably mounted on the sliders, and the sliders and the rotating ring are locked together by set screws.

[0013] In an improved version of the above implementation, a cover plate is provided on the connecting shaft between the fan plate and the outer ring, and the cover plate is fastened to the elongated hole.

[0014] In the optimized implementation described above, each set of outer rings is provided with a first diaphragm and a second diaphragm. The first diaphragm and the second diaphragm are fastened to the outside of the outer ring, and both the first diaphragm and the second diaphragm are fixed on the tube mill. The first diaphragm and the second diaphragm are fixedly connected by a lock nut.

[0015] In an improved version of the above implementation, a core disk is provided in the middle of the outer ring, and each of the sector plates is rotatably mounted on the outer circumferential wall of the core disk at its end facing the core disk.

[0016] The advantages of this invention are:

[0017] By adjusting the tilt angle of the baffle plates, automatic adjustment of material flow can be achieved. This allows the tube mill to quickly adapt to different processing conditions based on changes in material characteristics, such as hardness, humidity, and throughput fluctuations, improving overall operational flexibility and efficiency. The tilted design of the baffle plates not only promotes smooth material flow between different compartments but also acts as a screening mechanism, helping to prevent material blockage and ensuring material continuity and uniformity. By avoiding the downtime maintenance required for traditional baffle plate adjustments, this solution significantly reduces unplanned downtime, lowers the risk of production interruptions, and improves equipment availability and production continuity. In conclusion, the adaptive flow regulation baffle solution without baffle opening operations not only overcomes the limitations of traditional tube mills but also significantly improves the efficiency, stability, and economy of material processing, representing a significant technological innovation in the field of material processing.

[0026] 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.

[0027] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0029] like Figures 1 to 4 As shown, the adaptive flow regulating compartment of the present invention, which does not require opening, is used to automatically regulate the flow rate of material in the tube mill 1.

[0030] The device includes multiple sets of compartment structures 2 installed on the tube mill 1. The multiple sets of compartment structures 2 divide the interior of the tube mill 1 into multiple independent compartments. Each compartment structure 2 consists of an outer ring 3 fixed on the tube mill 1 and multiple fan plates 4 located within the outer ring 3. The outer ring 3 is coaxial with the tube mill 1. The multiple fan plates 4 are arranged in a ring. When the surface of the fan plate 4 is perpendicular to the axis of the tube mill 1, the multiple fan plates 4 are coplanar and block the outer ring 3. When the surface of the fan plate 4 is relatively inclined to the axis of the tube mill 1, the gap between two adjacent fan plates 4 is used for material flow. A connecting shaft 5 is provided in the middle of each fan plate 4. The connecting shaft 5 is arranged in the radial direction of the outer ring 3, and the end of the connecting shaft 5 is rotatably mounted on the outer ring 3.

[0031] In detail, when the tube mill 1 is used to crush materials, the materials can enter the tube mill 1 through one end. The tube mill 1 rotates, causing the grinding media inside to crush the materials. The materials move laterally inside the tube mill 1 and are discharged through the other end. Multiple sets of partition structures 2 divide the internal space of the tube mill 1 into multiple chambers, and the volume of the grinding media in each chamber gradually changes. In this way, when the materials pass through multiple chambers one by one, the grinding media in different chambers can achieve step-by-step crushing of the materials. The partition structure 2 is used to control the flow speed of the materials between different chambers. Specifically, the multiple fan plates 4 on the partition structure 2 use their respective... The connecting shaft 5 rotates along its axis to adjust the tilt angle of the fan plates 4. When multiple fan plates 4 are coplanar and perpendicular to the axis of the tube mill 1, they block the outer ring 3, isolating different chambers. When the fan plates 4 are tilted relative to the axis of the tube mill 1, gaps are created between adjacent fan plates 4. These gaps serve as material flow paths, allowing materials to flow between different chambers. In use, when material accumulates in one chamber and the amount of material being transported to the next chamber decreases, the size of the gaps can be adjusted by adjusting the tilt angle of the fan plates 4, thereby regulating the flow of material to the next chamber and achieving automatic flow regulation.

[0032] It should be noted that when the material is piled up, it is continuously crushed in the corresponding chamber. When the gap between two adjacent fan plates 4 is adjusted, the material that has been crushed in this chamber enters the next chamber. Since the fan plate 4 is tilted, when the fan plate 4 rotates with the tube mill 1, the inclined surface of the fan plate 4 can be used to guide the crushed material, reducing the risk of material accumulation and blockage. At the same time, the gap between two adjacent fan plates 4 can also play a role in screening the material. In this case, the angle of the fan plate 4 is adjusted by rotating the connecting shaft 5. This can avoid setting up other structures to control the rotating connecting shaft 5 and the fan plate 4 in the chamber between two adjacent sets of partition structures 2, so as not to affect the impact movement of the grinding media in the chamber.

[0033] In actual assembly, the tube mill 1 can be composed of multiple single cylinders, with a partition structure 2 sandwiched between two adjacent single cylinders, thus forming a complete tube mill 1.

[0034] By adjusting the tilt angle of the baffle plate 4, the material flow rate can be automatically adjusted. This allows the tube mill 1 to quickly adapt to different processing conditions based on changes in material characteristics, such as hardness, humidity, and throughput fluctuations, thus improving the overall operational flexibility and efficiency. The tilt design of the baffle plate 4 not only promotes smooth material flow between different compartments but also plays a certain screening role, helping to prevent material blockage between compartments and ensuring material continuity and uniformity. By avoiding the downtime maintenance required for traditional compartment plate adjustments, this solution significantly reduces unplanned downtime, lowers the risk of production interruption, and improves equipment availability and production continuity. In summary, the adaptive flow regulation compartment scheme without compartment opening operation not only overcomes the limitations of traditional tube mills but also significantly improves the efficiency, stability, and economy of the material processing process, representing a significant technological innovation in the field of material processing.

[0035] like Figure 5 As shown, a circular groove is formed on the outer circumference of the outer ring 3, and multiple elongated holes 6 are formed in the groove to communicate with the inside of the tube mill 1. The multiple elongated holes 6 are arranged in a ring. The length direction of the elongated holes 6 is parallel to the axis of the tube mill 1. A movable ring 7 is slidably sleeved in the circular groove. The connecting shaft 5 passes through the elongated holes 6 and the movable ring 7 and is rotatably mounted on the movable ring 7.

[0036] The moving ring 7 is equipped with a transmission structure. When the moving ring 7 moves along the axis of the tube mill 1 in the circular groove, the transmission structure drives each connecting shaft 5 to rotate.

[0037] In detail, when the material settles in the chamber, the amount of material increases, and the material will generate a lateral thrust on the compartment structure 2. At this time, the lateral thrust will act on the moving ring 7 through the fan plate 4 and the connecting shaft 5. The moving ring 7 will move in the circular groove on the outer ring 3. The moving ring 7 drives the connecting shaft 5 to rotate through the transmission structure, thereby causing the angle of the fan plate 4 to change.

[0038] With the above-described structure, the tilt angle of the fan plate 4 can be automatically adjusted by the amount of material in the chamber, without the need for additional power or electrical control equipment, enabling the material to regulate its own flow rate.

[0039] like Figure 5 As shown, the transmission structure includes a rotating ring 8 rotatably sleeved on a moving ring 7, a plurality of gears 9 meshing on the rotating ring 8, and the plurality of gears 9 being respectively mounted on a plurality of connecting shafts 5;

[0040] Multiple inclined arms 10 are rotatably provided on the rotating ring 8. The inclined arms 10 are inclined relative to the axis of the tube mill 1. An insert shaft 11 is provided at the end of the inclined arm 10 away from the rotating ring 8. One end of the insert shaft 11 slides through the inclined arm 10, and the other end of the insert shaft 11 is provided with a connecting wheel 12. The connecting wheel 12 is rotatably mounted on the outer ring 3.

[0041] In detail, when the moving ring 7 moves, it can drive the rotating ring 8 to move synchronously. Since the length of the inclined arm 10 is fixed, when the distance between the moving ring 7 and the connecting wheel 12 changes, the inclined arm 10 will pull the rotating ring 8 to rotate on the moving ring 7. Since the rotating ring 8 meshes with the gear 9, the rotating ring 8 will drive the connecting shaft 5 and the fan plate 4 to rotate through the gear 9, thereby realizing the adjustment of the angle of the fan plate 4. This adjustment method converts the pushing force of the accumulated material on the moving ring 7 into the rotational power of the fan plate 4.

[0042] It should be noted that when the rotating ring 8 rotates on the moving ring 7, the inclined arm 10 tilts and slides on the insert shaft 11, which drives the connecting wheel 12 to rotate, thereby ensuring the integrity of the structure and the smoothness of the movement.

[0043] like Figure 5 As shown, the movable ring 7 is provided with a plurality of spring pieces 13, and each spring piece 13 is provided with a connecting post 14, which is rotatably mounted on the rotating ring 8.

[0044] In detail, when the rotating ring 8 rotates on the moving ring 7, the rotating ring 8 will drive the spring piece 13 to undergo elastic deformation through the connecting post 14, thereby using the spring piece 13 to provide a reset elastic force for the rotating ring 8, the moving ring 7 and the fan plate 4.

[0045] like Figure 5 As shown, multiple sliders 15 are slidably arranged on the rotating ring 8, and the connecting post 14 is rotatably mounted on the sliders 15. The sliders 15 and the rotating ring 8 are locked together by a set screw 16.

[0046] In detail, by adjusting the position of the slider 15 on the rotating ring 8, the initial elastic force of the spring piece 13 can be adjusted, thereby adjusting the threshold of the force that the accumulated material provides to the fan plate 4.

[0047] like Figure 4 As shown, a cover plate 17 is provided on the connecting shaft 5 between the fan plate 4 and the outer ring 3, and the cover plate 17 is fastened to the elongated hole 6.

[0048] In detail, by setting the cover plate 17, the elongated hole 6 can be blocked, thereby preventing the material in the tube mill 1 from being discharged through the elongated hole 6. When the fan plate 4 moves and rotates, the connecting shaft 5 drives the cover plate 17 to move synchronously.

[0049] like Figure 1 As shown, each outer ring 3 is provided with a first partition 18 and a second partition 19. The first partition 18 and the second partition 19 are fastened to the outside of the outer ring 3, and both the first partition 18 and the second partition 19 are fixed on the tube mill 1. The first partition 18 and the second partition 19 are fixedly connected by a lock nut.

[0050] In detail, the first diaphragm 18 and the second diaphragm 19 are both located on the outer wall of the tube mill 1, and the first diaphragm 18 and the second diaphragm 19 can be combined to shield and protect the structure on the outer ring 3. When it is necessary to adjust the set screw 16, the first diaphragm 18 and the second diaphragm 19 can be separated.

[0051] like Figure 3 As shown, a core disk 20 is provided in the middle of the outer ring 3, and each of the fan plates 4 is rotatably mounted on the outer circumferential wall of the core disk 20 at the end facing the core disk 20.

[0052] In detail, one end of the fan plate 4 is connected to the outer ring 3, and the other end of the fan plate 4 is connected to the core disk 20. In this way, multiple fan plates 4 can be interconnected through the core disk 20, thereby providing auxiliary support for multiple fan plates 4.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
