Description

Technical Field

[0001] This utility model relates to the field of sintering raw material mixing technology, and in particular to a cylindrical mixer. Background Technology

[0002] In the sintering production process, the cylindrical mixer is a crucial piece of equipment. Its main function is to mix and granulate the sintering raw materials, providing qualified materials for subsequent sintering processes. As a typical heavy-duty piece of equipment, the cylindrical mixer needs to continuously process large quantities of materials. During long-term high-load operation, its components are subjected to significant stress and wear.

[0003] The coupling, as a key transmission component connecting the drive motor and the mixing cylinder, plays a crucial role in transmitting torque. However, due to the large volume and complex characteristics of the materials processed by the cylindrical mixer, coupling breakage frequently occurs during actual operation due to excessive material weight or inherent problems with the coupling itself.

[0004] When the coupling breaks, the mixing cylinder stops operating due to loss of power, but the drive motor remains unloaded. Simultaneously, the feeding system from the preceding process continues to supply material, causing a continuous influx of material into the cylindrical mixer. Since the mixing cylinder has stopped operating, the incoming material cannot be properly conveyed and processed, gradually accumulating in large quantities within the cylinder, leading to severe blockage and exacerbating the equipment malfunction. This can also disrupt the entire sintering production process, reducing production efficiency.

[0005] Therefore, there is an urgent need for a cylindrical mixer to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cylindrical mixer that can prevent equipment failure from escalating, reduce maintenance costs, and minimize the impact of the first coupling breakage. This protects core equipment such as the drive unit and the mixing cylinder, while also avoiding safety risks and production losses.

[0007] To achieve the above objectives, the following technical solution is provided:

[0008] A cylindrical mixer, comprising:

[0009] Mixing cylinder;

[0010] The driving mechanism includes a driving component and a first coupling, wherein the output end of the driving component drives the mixing cylinder to rotate about its own axis through the first coupling.

[0011] The detection mechanism includes a trigger and at least two detection elements. The trigger is disposed on the first coupling, and the at least two detection elements are arranged at intervals along the axial direction of the first coupling. The at least two detection elements are respectively signal-connected to the drive element and can be triggered by the trigger.

[0012] As an optional solution, the drive mechanism further includes:

[0013] A speed reducer and a second coupling are provided. The speed reducer is disposed between the driving component and the first coupling. The speed reducer is connected to the output end of the driving component through the second coupling. The detection mechanism is provided at the second coupling.

[0014] As an optional feature, the cylindrical mixer further includes:

[0015] The support mechanism rolls in conjunction with the mixing cylinder.

[0016] As an optional solution, the support mechanism includes a support base and a rolling element, the rolling element being rotatably connected to the support base, the mixing cylinder including a main body and a support ring, the support ring being sleeved on the outer periphery of the main body, and the rolling element being in rolling engagement with the support ring.

[0017] As an optional solution, the main body is provided with a feed inlet and a discharge outlet at both ends along the axial direction.

[0018] As an optional feature, the cylindrical mixer further includes:

[0019] A liner plate is disposed on the inner wall of the main body.

[0020] As an option, the number of support mechanisms is multiple, and the multiple support mechanisms are arranged at intervals along the circumferential and / or axial direction of the mixing cylinder.

[0021] As an optional solution, the mixing cylinder is set at an angle to the horizontal plane.

[0022] As an optional solution, the angle between the mixing cylinder and the horizontal plane is 1°-5°.

[0023] As an optional solution, a water pipe is provided inside the mixing cylinder, and multiple water outlets are provided on the water pipe, which are arranged at intervals along the axial and / or circumferential direction of the water pipe.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The cylindrical mixer provided by this utility model has the following characteristics: When the drive unit is working, the trigger element rotates with the first coupling. At least two detection elements can periodically detect the signal of the trigger element. When the first coupling breaks, the detection elements cannot detect the trigger element or continuously receive the signal of the trigger element. This is an abnormal state. When the drive unit receives the signal of the detection elements detecting the abnormal state, it stops operating, thus avoiding the expansion of equipment failure, reducing maintenance costs, and minimizing the impact of the first coupling breakage. This protects the core equipment such as the drive unit and the mixing cylinder, and avoids safety risks and production losses. Attached Figure Description

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a cylindrical mixer 100 for mixing and granulating sintering raw materials. Specifically, the cylindrical mixer 100 includes a mixing cylinder 10 and a drive mechanism 20. The drive mechanism 20 can drive the mixing cylinder 10 to rotate around its own axis. The materials inside the mixing cylinder 10 are continuously lifted and scattered under the pushing action of gravity, friction, and the inner wall of the mixing cylinder 10, forming a "tumbling" motion. In this process, different types of raw materials gradually achieve a uniform distribution of components through repeated collisions and mixing.

[0043] Optionally, the cylindrical mixer 100 also includes a support mechanism 40, which is in rolling engagement with the mixing cylinder 10. By providing the support mechanism 40, the weight of the mixing cylinder 10 and the load of the material can be borne, ensuring the stable rotation of the mixing cylinder 10.

[0044] Optionally, the support mechanism 40 includes a support base 41 and a rolling element 42, the rolling element 42 being rotatably connected to the support base 41. The mixing cylinder 10 includes a main body 11 and a support ring 12, the support ring 12 being sleeved on the outer periphery of the main body 11, and the rolling element 42 rollingly engaging with the support ring 12. This protects the main body 11, prevents wear on the main body 11, and also prevents the main body 11 from shifting during rotation.

[0045] Optionally, there may be multiple support mechanisms 40, which are arranged at intervals along the circumference and / or axial direction of the mixing cylinder 10 to balance the gravity load, prevent the mixing cylinder 10 from bending and deforming, reduce vibration and noise, and improve the stability of equipment operation.

[0046] Optionally, the main body 11 is provided with a feed inlet 111 and a discharge outlet 112 at both ends along its axial direction. Various raw materials (such as iron ore, fuel, flux, return ore, etc.) are continuously and stably fed into the main body 11 through the feed inlet 111 in proportion by a belt conveyor or feeder. After the materials reach the preset mixing degree in the mixing cylinder 10, they are transferred to the next process through the discharge outlet 112 by a belt conveyor.

[0047] Optionally, the drive mechanism 20 includes a drive element 21 and a first coupling 22. The output end of the drive element 21 drives the mixing cylinder 10 to rotate around its own axis via the first coupling 22. A first gear 13 is provided on the outer periphery of the main body 11, and a second gear 25 is provided on the output end of the first coupling 22. The first gear 13 and the second gear 25 mesh with each other. The drive element 21 drives the second gear 25 to rotate via the first coupling 22, thereby driving the first gear 13 to rotate, so as to drive the main body 11 to rotate around its own axis. By providing the first coupling 22, the installation error between the output shaft of the drive element 21 and the second gear 25 can be compensated. The drive element 21 can be an existing motor or hydraulic cylinder.

[0048] Because the cylindrical mixer 100 is a heavy-duty piece of equipment, the first coupling 22 often breaks due to excessive material weight during operation. When the first coupling 22 breaks, the mixing cylinder 10 stops operating due to loss of power, but the drive component 21 remains unloaded. Simultaneously, the feeding system of the preceding process continues to supply material, causing a continuous influx of material into the cylindrical mixer 100. Since the mixing cylinder 10 has stopped operating, the incoming material cannot be properly conveyed and processed, gradually accumulating in large quantities within the mixing cylinder 10, leading to severe material blockage and exacerbating equipment failure. It can also cause the entire sintering production process to be interrupted, reducing production efficiency.

[0049] To address the aforementioned issues, the cylindrical mixer 100 provided in this embodiment further includes a detection mechanism 30. The detection mechanism 30 comprises a trigger element 32 and two detection elements 31. The trigger element 32 is mounted on the first coupling 22, and the two detection elements 31 are arranged axially at intervals along the first coupling 22. Each detection element 31 is signal-connected to the drive element 21 and can be triggered by the trigger element 32. When the first coupling 22 rotates, the trigger element 32 rotates with it, and both detection elements 31 periodically detect the signal from the trigger element 32. When the first coupling 22 breaks, the detection element 31 either fails to detect the trigger element 32 or continuously receives the signal from the trigger element 32, indicating an abnormal state. Upon receiving the signal from the detection element 31 indicating an abnormal state, the drive element 21 stops operating, preventing the equipment failure from escalating, reducing maintenance costs, and minimizing the impact of the first coupling 22 breakage. This protects core equipment such as the drive element 21 and the mixing cylinder 10, while also mitigating safety risks and production losses. In other embodiments, the number of detection elements 31 may be three, four, or more, and designers can make an adaptive selection according to actual needs. Specifically, the detection element 31 may be a proximity switch.

[0050] Optionally, the drive mechanism 20 also includes a reducer 23 and a second coupling 24. The reducer 23 is disposed between the drive member 21 and the first coupling 22. The reducer 23 is connected to the output end of the drive member 21 through the second coupling 24, and the first coupling 22 is connected to the output end of the reducer 23. By setting the reducer 23, the speed of the drive member 21 can be adjusted to adapt to the load requirements, thereby improving transmission efficiency and operational stability.

[0051] Optionally, a detection mechanism 30 is provided at the second coupling 24 to prevent the second coupling 24 from breaking and causing the equipment failure to escalate. Specifically, a trigger 32 is provided on the second coupling 24, and at least two detection elements 31 are arranged at intervals along the axial direction of the second coupling 24. At least two detection elements 31 are respectively signal-connected to the drive element 21 and can be triggered by the trigger 32. The working process and working principle of the detection mechanism 30 provided at the second coupling 24 are the same as those of the detection mechanism 30 provided at the first coupling 22, and will not be described again here for the sake of brevity.

[0052] Optionally, the cylindrical mixer 100 also includes a liner (not shown in the figure), which is disposed on the inner wall of the main body 11 to resist direct wear of the main body 11 by the material, buffer impact loads, and improve the service life of the mixing cylinder 10.

[0053] Optionally, the mixing cylinder 10 is set at an angle to the horizontal plane to utilize gravity to assist the axial movement of materials, thereby achieving continuous production, optimizing the mixing effect, and improving mixing efficiency.

[0054] Optionally, the angle between the mixing cylinder 10 and the horizontal plane is 1°-5°. This avoids the problem that if the angle between the mixing cylinder 10 and the horizontal plane is too small, the axial component of gravity will be too small, the axial movement speed of the material will be too slow, and the mixing efficiency and effect will be reduced. At the same time, it avoids the problem that if the angle between the mixing cylinder 10 and the horizontal plane is too large, the axial component of gravity will be too large, the axial movement speed of the material will be too fast, and the material will not be fully mixed.

[0055] Optionally, a water pipe 50 is provided inside the mixing cylinder 10, and multiple water outlets are provided on the water pipe 50. The water outlets are arranged at intervals along the axial and / or circumferential direction of the water pipe 50. The water pipe 50 is used to connect to a water source so as to spray water into the mixing cylinder 10 to regulate the humidity of the material, promote uniform mixing of the material, and avoid stratification and segregation.
