Description

Technical Field

[0001] This invention relates to the field of rotary material handling equipment technology, and more specifically to a rotary material handling equipment that utilizes accompanying heating and / or crushing of materials. Background Technology

[0002] Rotary kilns are important industrial heat treatment equipment, widely used in industries such as cement, metallurgy, and chemicals. They are used for processes such as sintering, roasting, and calcining of materials, offering advantages such as continuous production and high thermal efficiency. Existing rotary kilns mainly consist of a rotating device (generally a rotary drum), a rotating support device (usually including a tire, support rollers, etc.), a drive device (usually including gears, motors, etc.), a feeding device, a discharging device, and a heating device. The rotary drum is the core component of the entire rotary kiln; it is cylindrical and installed at a slight inclination. The tire is fitted around the outside of the rotary drum, and the support rollers are located below the tire, supporting the weight of the tire and the rotary drum. The motor of the drive device drives the gears, thereby rotating the rotary drum. The feeding device is located at the feeding end (high end / kiln tail end) of the rotary drum and has a sealing device between it and the kiln tail. The discharging device is located at the discharging end (low end / kiln head end) of the rotary drum and has a sealing device between it and the kiln head. In externally heated rotary kilns, the heating device is located outside the rotary drum, while in internally heated rotary kilns, the heating device is located inside the rotary drum. The rotary drum rotates, causing the material to roll along the inner wall of the drum under the action of gravity, while simultaneously exchanging heat fully with the heat source of the heating device.

[0003] Patent document CN102494535A discloses a rotary kiln. Its core technical concept involves placing grinding media inside the rotary device. The impact and friction of the grinding media keep the mineral powder dispersed to prevent ring formation. A spiral belt guide is used to transport the grinding media and material together to the discharge end. After discharge, the material and grinding media are cooled and separated, and the grinding media are recycled for reuse. The main problem with this technical solution is that it cannot achieve online recycling of the grinding media. Cooling is required before material separation, and this offline process consumes a large amount of grinding media to ensure continuous production. Furthermore, the grinding media only serves the single function of preventing ring formation and does not fully consider its potential as a heat transfer medium. Even if the grinding media objectively provides some heat transfer, repeated cooling results in significant energy waste.

[0004] Patent document CN201407891Y discloses a ball mill rotary furnace. Its core technical concept involves dividing the furnace tube (i.e., the rotary device) into a ball mill heating zone and a conventional heating zone using baffles with perforated screens. Ball milling media are placed in the ball mill heating zone to grind and mix materials. The distribution of the ball milling media is controlled by the perforated screens on the baffles, allowing the material to undergo ball milling and conventional heating treatments in different zones respectively. The main problems with this technical solution are: the ball milling media is fixed and confined to a specific ball mill heating zone, preventing continuous recycling throughout the entire process, resulting in grinding effects limited to a localized area; while the baffle structure can separate different functional zones, it also hinders the free flow and circulation of the ball milling media, causing it to function only in a fixed zone and failing to fully utilize its potential as a heat transfer carrier throughout the material processing.

[0005] Furthermore, these rotary kilns suffer from a fixed and non-adjustable tilt angle. This prevents flexible adjustment of the kiln's tilt angle based on different material characteristics, process requirements, and production conditions, resulting in an inability to optimize the material's residence time, flow rate, and heat transfer within the kiln. The fixed tilt angle makes rotary kilns unsuitable for processing materials with varying densities, viscosities, and flowability. This is particularly problematic when precise control of material residence time is required to achieve specific reaction rates or product quality requirements. The inability to adjust the tilt angle for refined process control severely limits the rotary kiln's process flexibility and production adaptability. Summary of the Invention

Through the cooperation of the material circulation channel and the material drive structure, the recovered material is returned to the material addition structure for recycling, avoiding the problem of offline separation after cooling in existing technologies. This significantly reduces the consumption of material, lowers energy consumption, and ensures the continuity of production, significantly improving the economy and process efficiency of the rotary material handling equipment.

Detailed Implementation

[0033] The present invention will now be clearly and completely described in conjunction with the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention in conjunction with the accompanying drawings, it should be particularly noted that:

[0034] The technical solutions and features provided in the various sections, including the following description, can be combined with each other without conflict. Furthermore, where possible, these technical solutions, features, and related combinations can be given specific technical subject matter and protected by relevant patents.

[0035] The embodiments of the present invention described below are generally only some embodiments and not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of patent protection.

[0036] The terms "comprising," "including," "having," and any variations thereof in this specification, the corresponding claims, and related sections are intended to cover non-exclusive inclusion. Other related terms and units can be reasonably interpreted based on the relevant content provided in this specification.

[0037] like Figure 1 As shown, the rotary material handling device provided in this embodiment of the invention includes a rotary device 1, a rotary support device 2, a rotary drive device 3, a heating device (not shown in the figure), and a swing-type lifting platform 5.

[0038] The rotary device 1 is cylindrical (rotary drum) and has a feed end and a discharge end. A material flow channel is formed between the feed end and the discharge end in the rotary device 1. During operation, the material flows from the feed end to the discharge end through the material flow channel. Under normal operating conditions, the feed end is at a higher position relative to the discharge end, and the rotary device 1 forms a downward tilt angle, allowing the material to flow smoothly along the material flow channel under the action of gravity.

[0039] The rotating support device 2 is mounted on the base 4 and includes multiple sets of tires 21 and support rollers 22. The rotating device 1 is mounted on the support rollers 22 via the tires 21. The support rollers 22 are mounted on the swing-type lifting platform 5 described below, thereby providing rotational support for the rotating device 1.

[0040] The rotary drive device 3 includes a motor 31 and a gear transmission mechanism. The small gear 32 in the gear transmission mechanism is mounted on the output shaft of the motor 31, and the large gear 33 in the gear transmission mechanism is sleeved on the rotary device 1. The small gear 32 and the large gear 33 mesh with each other, thereby driving the rotary device 1 to perform rotary motion.

[0041] The heating device is located outside the rotary device 1. During the rotary motion of the rotary device 1, the material entering from the feed end and flowing through the material flow channel to the discharge end is heated.

[0042] The heating device can use various heating methods such as gas heating, electric heating, and electromagnetic heating to directly heat the side wall of the rotary device 1, thereby transferring heat to the internal material.

[0043] One end of the swing-type lifting platform 5 is connected to the base 4 via hinge point 51, and the other end of the swing-type lifting platform 5 is connected to the base 4 via lifting device 52, which is a hydraulic lifting cylinder. The base 4 forms the foundation of the entire rotary material handling device.

[0044] The aforementioned rotary support device 2 and rotary drive device 3 are integrally mounted on the swing-type lifting platform 5, and the feeding end of the rotary device 1, which is mounted on the swing-type lifting platform 5 via the rotary support device 2, is located on the side of the lifting device 52, while the discharging end is located on the side of the hinge point 51.

[0045] In addition, the swing-type lifting platform 5 is also equipped with a feeding device 6, the outlet of which is connected to the inlet. The feeding device 6 is used to transport the material to be processed to the inlet of the rotary device 1, ensuring the continuity of the production process.

[0046] The design of the swing-type lifting platform 5 allows for flexible adjustment of the tilt angle of the rotary device 1. When the lifting equipment 52 is raised or lowered, the swing-type lifting platform 5 swings around the hinge point 51, thereby changing the tilt angle of the rotary device 1 to adapt to different process requirements and production conditions.

[0047] like Figures 2-5 As shown, the rotary material handling device also includes an online material circulation device 7, which is connected to the rotary device 1 and includes a material feeding structure, a material recovery structure, a material circulation channel, and a material driving structure.

[0048] The additive addition structure is located at the additive addition position of the rotary device 1, and is used to add additives to the material, thereby mixing the additives with the material to form a mixture. The additive recovery structure is located at the additive recovery position of the rotary device 1, and is used to recover the additives from the mixture.

[0049] The material circulation channel connects the material recycling structure and the material addition structure, and is used to return the material recycled from the material recycling structure to the material addition structure.

[0050] In different application scenarios, the location for adding and recycling materials can be flexibly set according to process requirements. For example, the location for adding materials can be set at the feed end, the middle section of the material flow channel, or near the discharge end, and the location for recycling materials can also be set at different locations in the material flow channel accordingly.

[0051] In this embodiment, in order to fully utilize and effectively circulate the accompanying material, the accompanying material is added near the feed end, while the accompanying material is recycled at the discharge end. This arrangement allows the accompanying material to accompany the material through the entire heating and processing process, maximizing the heat transfer and crushing functions of the accompanying material.

[0052] The material-carrying drive structure is connected to the rotary device 1 by transmission, so that the rotary motion of the rotary device 1 serves as the driving force of the material-carrying drive structure, which drives the material to move in the material-carrying circulation channel during the rotary motion of the rotary device.

[0053] The design of the material handling drive structure and the transmission connection of the rotary device 1 avoids the need for an additional power source, greatly reducing the complexity and energy consumption of the rotary material handling device, while ensuring the synchronization of the material circulation with the main process. This transmission connection can be achieved in various ways, including mechanical connections such as gear transmission, belt transmission, chain transmission, and friction transmission.

[0054] In this embodiment, after the additive is mixed with the material, the additive acts as a heat transfer carrier to transfer the heat from the heating device to the material, and the additive crushes the material through mechanical action.

[0055] The heat transfer material is typically made of materials with good thermal conductivity, high temperature resistance, and a certain degree of mechanical strength. These can be metallic materials such as steel balls, iron balls, or stainless steel balls, or ceramic materials such as alumina balls or zirconia balls. A spherical shape is optimal for the heat transfer material because it has the smallest surface area to volume ratio, resulting in low rolling resistance. The spherical structure also ensures good flowability and uniform heat transfer. The size of the heat transfer material is usually selected based on the material characteristics and processing requirements, generally ranging from a few millimeters to tens of millimeters in diameter. This ensures sufficient heat transfer area while facilitating separation and recovery from the main material.

[0056] In a preferred embodiment, the material circulation channel is a spiral material circulation channel 71 disposed on the rotary device 1. The spiral material circulation channel 71 is centered on the rotation center line of the rotary device 1 and follows the rotary device 1 in the same rotational motion. When the spiral material circulation channel 71 rotates, the material entering the spiral material circulation channel 71 from the material recovery structure moves towards the material addition structure under the action of centrifugal force and is finally discharged from the material addition structure.

[0057] This ingenious design fully utilizes the rotational motion of the rotary device 1 itself as the driving force for the conveying of accompanying materials (that is, the rotary device 1 itself can be regarded as a "material-carrying drive structure"), realizing the automatic cyclic conveying of accompanying materials. When the spiral material-carrying channel 71 rotates synchronously with the rotary device 1, the accompanying materials in the channel are subjected to the combined effects of centrifugal force, gravity, and channel wall constraint force, and can only move forward along the spiral trajectory. This not only eliminates the need for an additional power source and significantly simplifies the material-carrying drive structure, but also ensures the continuity and stability of the material circulation.

[0058] Furthermore, the spiral material mixing channel 71 is disposed on the inner side of the side wall of the rotary device 1, so that the spiral material mixing channel 71 is located in the material flow channel. One end of the spiral material mixing channel 71 is located in the feed end and serves as the material mixing inlet, and the other end of the spiral material mixing channel is located in the discharge end and serves as the material mixing recovery outlet.

[0059] The design of placing the spiral material mixing channel 71 on the inner side wall of the rotary device 1 has several significant advantages. First, the spiral material mixing channel 71 can directly contact the material, and its outer surface forms a natural guiding structure that guides the material to flow orderly along the spiral trajectory, preventing material deviation or accumulation during rotation. Simultaneously, the stirring effect of the spiral structure promotes uniform mixing and heat distribution. Second, this built-in design provides conditions for the installation and arrangement of external heating devices on the rotary device 1. Third, the spiral material mixing channel 71, located on the inner side wall of the rotary device 1, effectively forms an additional heat storage structure inside the rotary device 1, reducing heat loss to the external environment and improving thermal energy utilization efficiency.

[0060] Because the additives and the raw materials differ in physical properties such as particle size and density, these differences can be used to achieve effective separation of the additives and the raw materials. Based on this idea, such as... Figure 4 As shown, the material recovery structure is located at the discharge end and specifically includes a mixed material screening mechanism and a mixed material collection mechanism.

[0061] The mixture screening mechanism is used to screen the mixture that is running to the discharge end, allowing smaller particles to pass through and be discharged from the discharge end, while intercepting larger particles in the discharge end. A mixed material collection mechanism is located at the discharge end to collect the mixed materials intercepted by the mixture screening mechanism and guide the collected mixed materials into the mixed material circulation channel through a mixed material recovery port.

[0062] The advantage of a mixed material screening mechanism lies in its full utilization of the inherent physical differences between the accompanying materials and the raw materials, achieving simple and efficient automatic separation. Screening separation is a mature and reliable physical separation technology, characterized by high separation efficiency, simple operation, and low maintenance costs, requiring no complex control system or additional energy consumption. By rationally designing the screen aperture size, it can be ensured that most of the accompanying materials are effectively intercepted and recovered, while the processed material can be smoothly discharged, avoiding waste of accompanying materials and the problem of accompanying materials remaining in the raw materials.

[0063] In a preferred embodiment, the mixture screening mechanism includes a mixture screening cylinder formed by grid holes 11 formed on the side wall of the discharge end of the rotary device 1. A sealing cover 8 is installed on the outside of the mixture screening cylinder, and a discharge port 81 is provided at the bottom of the sealing cover 8.

[0064] By directly creating the grid holes 11 on the discharge end sidewall of the rotary device 1 to form a mixture screening cylinder, the structure of the mixture screening mechanism is simplified. By integrating the screening function directly into the structure of the rotary device 1 itself, the need for a separate screening device is completely eliminated, achieving a high degree of integration between the rotary device 1 and the mixture screening mechanism. This not only significantly reduces the complexity and manufacturing cost of the mixture screening mechanism but also fully utilizes the rotational motion of the rotary device 1 as the driving force for screening. During rotation, the mixture naturally contacts the grid holes 11 and is screened.

[0065] In addition, a vibration device can be connected to the mixture screening mechanism. In this embodiment, the vibration device includes an arc-shaped vibration generating cavity 9 that is attached to the inner side of the mixture screening cylinder and is coaxial with the rotation center line of the rotary device 1. Collision plates are respectively installed at both ends of the arc-shaped vibration generating cavity 9. A rolling ball is placed between the collision plates at both ends of the arc-shaped vibration generating cavity 9. A vibration transmission channel (which can be a hole or a groove) is provided on the contact surface between the arc-shaped vibration generating cavity 9 and the mixture screening cylinder for conducting the grid hole 11 and the arc-shaped vibration generating cavity 9. When the rotary device 1 rotates, the rolling ball periodically hits the corresponding collision plate to generate vibration, which is then transmitted to the grid hole 11 through the vibration transmission channel.

[0066] This vibration device cleverly utilizes the rotational motion of the rotary device 1 to drive the rolling balls to periodically impact the collision plate within the arc-shaped vibration generating chamber 9, converting the rotational motion into effective vibrational energy. It generates a continuous and stable vibration effect without the need for an additional power source. This vibration acts directly on the grid holes 11 through the vibration transmission channel, effectively preventing clogging of the grid holes 11. Especially for materials with high viscosity or prone to agglomeration, the vibration ensures the continuity and stability of the screening process.

[0067] like Figures 4-5 As shown, in a preferred embodiment, the material screening cylinder is provided with an inner convex ring surrounded by a plurality of arc-shaped vibration generating cavities 9 arranged circumferentially. The inner convex ring forms a first material blocking structure that can restrict the accompanying material from crossing the inner convex ring. The accompanying material collection mechanism includes the first material blocking structure, and the accompanying material recovery port is located in the inner region of the first material blocking structure.

[0068] In addition, a spiral guide plate 12 is provided in the material flow channel, which forms a spiral guide channel around the rotation center line of the rotating device. One end of the spiral guide plate 12 near the inner convex ring forms a second baffle structure, which is included in the accompanying material collection mechanism. The accompanying material recovery port is located in the area formed between the first baffle structure and the second baffle structure.

[0069] In addition, multiple anti-fall-off baffles 13 are distributed on the spiral guide plate 12. These anti-fall-off baffles 13 are distributed in different parts of the spiral guide channel to prevent the mixture in the spiral guide channel from falling under the action of gravity. There is a third baffle structure formed by the anti-fall-off baffles 13 between the first baffle structure and the second baffle structure. The accompanying material collection mechanism includes the third baffle structure. The accompanying material recovery port is located in the area formed between the first baffle structure, the second baffle structure and the third baffle structure (e.g., Figure 4 (As shown).

[0070] In addition, several anti-aggregation baffles 14 are distributed in the spiral material guide channel. The anti-aggregation baffles 14 are located in the material-aggregating area between the spiral material guide plate 12 and the inner side of the side wall of the rotating device 1. When the inner side of the side wall of the rotating device 1 is provided with a spiral material-accompanying channel 71, the material-aggregating area includes the area formed by the intersection between the spiral material guide plate 12 and the spiral material-accompanying channel 71.

[0071] The first baffle structure is formed by an inner convex ring, which uses geometric constraints to prevent the mixed material from crossing the inner convex ring. The second baffle structure is formed by a spiral guide plate 12, which, combined with the flow characteristics of the spiral guide channel, blocks the mixed material during the spiral propulsion process. The third baffle structure is composed of an anti-fall baffle 13, which ensures the retention of the mixed material in the designated area by hindering the falling movement of the mixture under gravity. The collection area formed by this triple baffle structure can intercept and gather the screened mixed material to the maximum extent.

[0072] Meanwhile, the design of the spiral guide channel allows the material to flow orderly along the spiral trajectory during rotation, avoiding disorderly accumulation and stagnation of the material. The setting of the anti-aggregation baffle 14 further eliminates the material accumulation problem in areas prone to material accumulation, such as the intersection area of ​​the spiral guide plate 12 and the spiral accompanying channel 71, ensuring the smooth operation of the entire system.

[0073] During the operation of the rotary device 1, the mixture will naturally fall downwards due to gravity. This downward movement may cause the mixture to bypass the screening area and flow directly to the discharge end, thus affecting the screening effect and the efficiency of material recovery. The anti-falling baffle 13 effectively suppresses this gravity-driven downward movement by forming physical barriers at different parts of the spiral guide channel, forcing the mixture to flow in an orderly manner along the preset path of the spiral guide channel.

[0074] The foregoing has described the relevant content of the present invention. Those skilled in the art will be able to implement the present invention based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of the present invention.
