Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a vertical conveying device and a material conveying production line. Background Technology

[0002] In the field of vertical material handling in industrial applications, continuous transfer from high to low levels is a crucial element in achieving seamless production processes. Vertical conveying utilizes the material's own gravity or mechanical assistance to efficiently and safely transfer materials from higher levels (such as the upper floors of production workshops, the top of silos, or upstream machine positions) to lower levels (such as the ground, transport vehicles, or downstream machine positions). Simultaneously, it is essential to address issues such as material leakage, blockages, impact damage, and spatial adaptability.

[0003] For the lightweight solid waste treatment industry, exemplified by lithium battery electrode recycling, vertically laid-out processes typically involve vertical material conveying channels positioned upstream of crushers, shredders, and other equipment. This verticality places higher demands on the conveying equipment, requiring it to reduce material conveying speed to accommodate the upstream feeding needs of crushers, shredders, and other equipment, while also addressing complex issues such as material dispersion due to free fall and dust diffusion caused by pneumatic disturbances.

[0004] Existing technical solutions mainly employ vertical conveying methods such as screw conveyor systems, buffer silo feeding devices, curved deceleration pipelines, and tilting plate buffer mechanisms to process lightweight solid waste. However, each has the following problems: screw conveyors have high energy consumption and rapid equipment wear; buffer silo feeders are prone to structural fatigue and have insufficient feeding stability; curved deceleration pipelines can reduce material speed, but conveying efficiency is limited and they are prone to blockage; tilting plate mechanisms cannot adapt to fluctuations in the feed volume, and components are prone to permanent deformation. In addition, existing conveying methods require high sealing performance, especially for powder conveying. Vertical conveying widely uses rigid sealing structures. When the vibration generated during equipment operation is transmitted through the rigid interface, it causes the interface stress to increase nonlinearly, resulting in micron-level displacement of the flange connection bolts. Ultimately, this leads to localized plastic deformation of the sealing surface. Furthermore, the continuous vibration energy is transmitted to the sealing interface through the rigid structure, greatly accelerating the fatigue damage process of the material and significantly shortening the service life of the sealing structure. Summary of the Invention

[0005] The vertical conveying device provided in this application embodiment is used to reduce the vibration caused by the operation of upstream equipment and the vibration generated by the operation of the device itself, and can also effectively decelerate the conveyed material.

[0006] In a first aspect, embodiments of this application provide a vertical conveying device, comprising: a device body having a material conveying channel; a deceleration assembly disposed on the device body for reducing the conveying speed of material in the material conveying channel of the device body; a bearing assembly connected to the device body to absorb vibration of the device body; a feeding section and a discharging section, one end of the device body being sealed to the feeding section and the other end being sealed to the discharging section; and a vibration damping assembly disposed on the feeding section for damping vibration of the device body.

[0007] The vertical conveying device provided in this application has a simple structure. It absorbs vibrations generated by the operation of upstream equipment through vibration damping components, reduces the conveying speed of materials within the device body through deceleration components, and absorbs vibration energy generated by the operation of the device itself through load-bearing components. This application achieves vibration reduction and deceleration through the synergistic effect of mechanical decoupling and vibration energy dissipation, providing a highly reliable conveying device with low maintenance requirements.

[0008] In one possible implementation, the vibration damping assembly includes a first rod, a sleeve, a first elastic member, and a second rod; the first elastic member is disposed inside the sleeve, and the sleeve and the first elastic member are fitted onto the first rod; the second rod is embedded in the first rod, one of the first rod and the second rod is slidably connected to the sleeve, and the other is connected to the sleeve; one end of the first elastic member is connected to the first rod, and the other end is connected to the second rod.

[0009] Under the combined action of external force and the first elastic element, the first and second rods can move relative to each other and reset. The process of moving relative to each other and resetting can dissipate the vibration generated by the operation of the upstream equipment and the main body of the device.

[0010] In one possible implementation, the feeding section is a flexible section, and the two ends of the feeding section are respectively provided with first support plates extending radially away from the device body. The vibration damping component is connected to the two sets of first support plates.

[0011] The flexible feeding section effectively seals the upstream equipment and the main body of the vertical conveyor, while also absorbing vibrations from equipment operation. Vibrations from the equipment connected to both ends of the feeding section can be dissipated through the vibration damping components. In other words, vibrations from both the upstream equipment and the main body of the vertical conveyor are dissipated when transmitted to the feeding section, effectively protecting it. The synergistic effect of the vibration damping components and the flexible feeding section further dissipates vibrations transmitted from adjacent equipment, thereby improving the sealing performance of the vertical conveyor and better protecting the main body from the impact of vibrations from upstream equipment.

[0012] In one possible implementation, the vibration damping assembly further includes a support base, which is hinged to the first rod and / or the second rod, and the support base is connected to the first support plate by a first fastener.

[0013] Connecting the vibration damping component to the first support plate via a support base can improve the connection stability between the vibration damping component and the first support plate.

[0014] In one possible implementation, the deceleration assembly includes an impeller and a power component. The impeller is installed inside the device body, and the power component is installed outside the device body. The impeller rotates under the drive of the power component and drives the material to be transported.

[0015] Under the action of the rotating impeller, the movement direction of the material is changed to follow the rotation direction of the impeller, and the speed of the material is also controlled to the rotation speed of the impeller. The impeller and its matching power components provided in this application are embodiments of a deceleration assembly. They utilize the material's own gravity potential energy to achieve falling, and use a rotating impeller to decelerate the material. This avoids the high energy consumption problem caused by gravity conveying in long-distance vertical conveying devices, and can also alleviate the impact damage to downstream equipment caused by excessively fast material falling speed.

[0016] In one possible implementation, the power component includes a motor, a driving wheel, and a driven wheel. The output end of the motor is connected to the driving wheel, the driving wheel is connected to the driven wheel via a transmission belt, and the driven wheel is connected to the impeller.

[0017] The preferred motor is a variable frequency motor. By constantly controlling the impeller speed, the variable frequency motor forcibly controls the material conveying speed as it passes through the impeller, achieving a deceleration effect. The adjustable frequency of the variable frequency motor effectively controls the material conveying speed and also makes the vertical conveying device suitable for production lines with different processing capacity requirements, thus improving the versatility of the vertical conveying system.

[0018] In one possible implementation, the device body has a first inspection port, the position of which corresponds to the installation position of the impeller. The first inspection port is covered with a cover plate, which is structurally compatible with the first inspection port. The cover plate is connected to the device body by a second fastener, and a first sealing ring is provided between the cover plate and the device body.

[0019] The first inspection port is provided on the main body of the device to facilitate maintenance in case of impeller failure, and the first sealing ring can improve the sealing performance of the main body of the device.

[0020] In one possible implementation, the device also includes a chassis and a protective cover, with one end of the protective cover connected to the chassis and the other end connected to the device body. The chassis houses the motor, and the protective cover houses the drive pulley, the drive belt, and the driven pulley.

[0021] The chassis is used to mount and protect the motor, while the protective cover protects the impeller's transmission mechanism. The protective cover is connected to the chassis and the main body of the device, improving the overall compactness of the structure.

[0022] In one possible implementation, the discharge section is a flexible section, and a second support plate extends radially away from the device body from the discharge section. The bearing component is connected to the device body through the second support plate.

[0023] The inlet and outlet sections are flexible, which allows for sealing of the vertical conveying device. The second support plate serves as a connector between the load-bearing components and the main body of the device, connecting the two and transmitting the operating vibrations of the main body of the device.

[0024] In one possible implementation, the support assembly includes a pair of elastic element seats and a second elastic element connected between the elastic element seats. The elastic element seats are sleeved on the support rod, and the support rod is fixedly connected to one of the elastic element seats. The elastic element seat closest to the device body is fixedly connected to the second support plate.

[0025] The smallest unit of the load-bearing assembly consists of two elastic element seats, one second elastic element, and one support rod. The support rod limits and fixes the elastic element seats, preventing the second elastic element from shifting laterally.

[0026] In one possible implementation, the device further includes a fixing frame, an elastic element seat located away from the device body being fixedly connected to the fixing frame, and a support rod being fixedly connected to one of the fixing frame and the second support plate.

[0027] The function of the fixed frame is to bear and transmit the vibrations transmitted by the connected structure to the ground. The operating vibration of the device body is transmitted to the bearing component through the second support plate. The bearing component dissipates the vibration. If there is still vibration after the bearing component, it is transmitted to the ground by the fixed frame, and the ground absorbs the remaining vibration. This design also allows the device body to be suspended between upstream and downstream equipment, avoiding the load force at the connection interface between the vertical conveying device and the upstream and downstream equipment of this application.

[0028] In one possible implementation, the feeding section is configured as a first corrugated pipe, and / or the discharging section is configured as a second corrugated pipe, one end of the second corrugated pipe is connected to a second support plate, the second support plate is connected to the device body by a third fastener, and the other end of the second corrugated pipe has a discharge port.

[0029] The feeding section and / or discharging section are made of corrugated pipes. The corrugated pipes can improve the sealing of the connection between the device body and the downstream equipment, and can also absorb some of the vibration generated by the operation of the device body.

[0030] Secondly, this application provides a material conveying production line, including an upper machine station, a lower machine station, and the aforementioned vertical conveying device. The two ends of the vertical conveying device are respectively sealed to the upper machine station and the lower machine station. The vibration damping component of the vertical conveying device absorbs the vibration of the upper machine station, and the bearing component of the vertical conveying device absorbs the vibration of the device body.

[0031] The material conveying production line provided in this application has a vertical conveying device whose inlet is in direct contact with the upper machine position and whose outlet is in direct contact with the lower machine position. This reduces the space ratio of the vertical conveying device, improves the utilization rate of vertical space in the production line, and avoids the need for additional pipelines.

[0032] The vertical conveying device provided in this application embodiment achieves the effect of reducing not only the vibration that may be caused by the upstream equipment of the vertical conveying device and the vibration of the vertical conveying device itself, but also the effect of reducing the material conveying speed by setting vibration damping components in the feeding section and setting deceleration components and bearing components in the device body.

[0046] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] Figure 1 A schematic diagram of the structure of the vertical conveying device 2 provided in this application is shown below. Figure 1 As shown, the vertical conveying device 2 of this application can be applied to the conveying of lightweight solid materials.

[0049] Based on the above scenarios, it can be seen that the existing technology for conveying lightweight solid materials by using different equipment has technical problems such as high energy consumption, low conveying efficiency, easy blockage, and equipment vibration affecting the sealing effect.

[0050] The vertical conveying device 2 provided in this application solves the technical problems of high energy consumption, low conveying efficiency, easy blockage, and the impact of equipment operation vibration on sealing effect when conveying lightweight solid materials by setting up flexible inlet and outlet sections 24, setting vibration damping components 213 in the inlet section 21, and setting deceleration components 23 and bearing components 242 in the device body 22.

[0051] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0052] Figure 1 A vertical conveying device 2 provided in this application includes: a device body 22 and a deceleration assembly 23 disposed on the device body 22. The device body 22 has a channel for conveying materials.

[0053] The speed reduction assembly 23 is used to reduce the conveying speed of materials in the material conveying channel of the device body 22.

[0054] The support component 242 is connected to the device body 22 to absorb the vibration of the device body 22.

[0055] The feeding section 21 and the discharging section 24 are connected. One end of the device body 22 is sealed to the feeding section 21 and the other end is sealed to the discharging section 24.

[0056] Vibration damping component 213 is located in the feeding section 21 and is used to dampen the vibration of the device body 22.

[0057] like Figure 1 As shown, the vertical conveying device 2 includes a feeding section 21, a device body 22, and a discharging section 24. The vibration damping component 213 is disposed in the feeding section 21 and can absorb the vibration generated by the upstream and downstream equipment and the device body 22 during operation.

[0058] The device body 22 is equipped with a deceleration assembly 23, whose deceleration structure is located within the conveying channel of the device body 22. Material, via upstream equipment, moves freely into the device body 22 and reaches the deceleration structure of the deceleration assembly 23. Through the obstruction of the deceleration assembly 23 or a set rotational speed, the material's conveying speed is forcibly controlled to achieve a deceleration effect. The deceleration assembly 23 can be any component that can reduce the material speed; it can be a reversible structure that changes the flow direction, a buffer component that increases resistance, a spiral guide structure, a damping and back pressure control structure, etc., as long as it can achieve the desired material conveying speed within the device body 22.

[0059] The load-bearing component 242 is connected to the device body 22 and can absorb the vibration generated by the device body 22 itself when conveying materials. It can also bear the weight of the device body 22 and the materials. The load-bearing component 242 can be a support structure with elastic or damping functions.

[0060] The vertical conveying device 2 provided in this application has a simple structure. It absorbs the vibration generated by the operation of upstream equipment through the vibration damping component 213, reduces the conveying speed of materials in the device body 22 through the deceleration component 23, and absorbs the vibration energy generated by the operation of the device body 22 itself through the bearing component 242. This application achieves vibration reduction, deceleration and sealing effects through the synergistic effect of mechanical decoupling and vibration energy dissipation, providing a highly reliable conveying device with low maintenance requirements.

[0061] Furthermore, the vibration damping component 213 includes a first rod 2137, a sleeve 2136, a first elastic element 2135, and a second rod 2134; the first elastic element 2135 is disposed inside the sleeve 2136, and the sleeve 2136 and the first elastic element 2135 are sleeved on the first rod 2137.

[0062] The second rod 2134 is embedded in the first rod 2137. One of the first rod 2137 and the second rod 2134 is slidably connected to the sleeve 2136, and the other is connected to the sleeve 2136. One end of the first elastic member 2135 is connected to the first rod 2137, and the other end is connected to the second rod 2134.

[0063] like Figure 2 and Figure 6 As shown, the vibration damping assembly 213 includes a first rod 2137, a second rod 2134, a sleeve 2136, and a first elastic element 2135. The first elastic element 2135 is disposed within the sleeve 2136, and the second rod 2134 is embedded within the first rod 2137, with the first rod 2137 and the second rod 2134 slidably connected. The first rod 2137 and the second rod 2134 at least partially penetrate the sleeve 2136 and the first elastic element 2135, and within the sleeve 2136, the first rod 2137 and the second rod 2134 at least partially overlap. Specifically, one of the first rod 2137 and the second rod 2134 is slidably connected to the sleeve 2136, and the other is fixedly connected to the sleeve 2136. The first rod 2137 and the second rod 2134 are respectively fixedly connected to both ends of the first elastic element 2135, which can be a spring. In this way, the first rod 2137 and the second rod 2134 can move relative to each other and reset under the combined action of external force and the elastic force of the first elastic member 2135. The process of moving relative to each other and resetting can dissipate the vibration generated by the operation of the upstream equipment and the main body 22.

[0064] Furthermore, the feeding section 21 is a flexible section, and the two ends of the feeding section 21 extend radially away from the device body 22 with first support plates 211, and the vibration damping component 213 is connected to the two sets of first support plates 211.

[0065] The feed section 21 is designed as a flexible section, made of a deformable material to ensure a sealed connection with the device body 22. Specifically, the flexible section can be made of a high-strength, corrosion-resistant, and long-service-life elastic material, such as TPEE (linear thermoplastic elastomer) or neoprene rubber. The flexible section can absorb some of the vibrations that may occur during the operation of upstream equipment. The flexible feed section 21 improves the sealing performance of the connection between the device body 22 and the upstream equipment.

[0066] like Figure 2 and Figure 3 As shown, first support plates 211 extend outward from both ends of the feeding section 21. One end of the vibration damping component 213 is connected to one of the first support plates 211, and the other end of the vibration damping component 213 is connected to the other first support plate 211. Vibrations generated by the operation of the equipment connected to both ends of the feeding section 21 can be dissipated by the vibration damping component 213. That is, the operating vibration of the upstream equipment of the vertical conveying device 2 and the vibration of the device body 22 itself transmitted to the feeding section 21 can be dissipated. The vibration damping component 213 can effectively protect the feeding section 21. The synergistic effect of the vibration damping component 213 and the flexible feeding section 21 can further dissipate the operating vibration transmitted by adjacent equipment, thereby improving the sealing performance of the vertical conveying device 2 and better protecting the device body 22 from the operating vibration of the upstream equipment.

[0067] Furthermore, the vibration damping assembly 213 also includes a support base 2133, which is hinged to the first rod 2137 and / or the second rod 2134, and the support base 2133 is connected to the first support plate 211 via a first fastener 2131.

[0068] To improve the connection stability between the vibration damping component 213 and the first support plate 211, such as Figure 6 As shown, the vibration damping component 213 also includes a support base 2133. The support base 2133 is provided at the connection end between the first rod 2137 and the second rod 2134 and the first support plate 211. The support base 2133 is hinged to the first rod 2137 and the second rod 2134. Specifically, the support base 2133 can be hinged to the first rod 2137 and the second rod 2134 via a pin shaft 2132. It should be noted that the support base 2133 can be provided on only one of the first rod 2137 and the second rod 2134, or both can be provided. There is no restriction here, as long as a stable connection between the vibration damping component 213 and the first support plate 211 can be achieved.

[0069] In addition, the support base 2133 is hinged to the first rod 2137 and the second rod 2134, so that the support base 2133 and the first rod 2137 and the second rod 2134 can move relative to each other through the hinge axis, thereby preventing damage to the connection structure between the support base 2133 and the first rod 2137 and the second rod 2134 when vibration is transmitted to the support base 2133.

[0070] The support base 2133 is structurally compatible with the first support plate 211. If the first support plate 211 is a planar structure, the part connecting the support base 2133 and the first support plate 211 can also be a planar structure, making the connection between the two via the first fastener 2131 more stable. The first fastener 2131 can be a bolt, or any connector that can achieve a stable connection between the first support plate 211 and the support base 2133.

[0071] Furthermore, the deceleration assembly 23 includes an impeller 233 and a power component. The impeller 233 is installed inside the device body 22, and the power component is installed outside the device body 22. The impeller 233 rotates under the drive of the power component and drives the material to be transported.

[0072] The reduction gear assembly 23 uses an impeller 233 as the reduction structure as one embodiment of the reduction gear assembly 23. In this embodiment, as follows: Figure 4 and Figure 7 As shown, the impeller 233 is installed inside the channel of the device body 22, while the power component that provides power to the impeller 233 is installed outside the device body 22. Driven by the power component, the impeller 233 rotates at a certain speed. The speed of the material falling freely inside the device body 22 differs from the speed of the impeller 233, and the direction of material movement also differs from the direction of impeller rotation. Under the action of the rotating impeller 233, the direction of material movement is changed to follow the rotation direction of the impeller 233, and the speed of the material is also controlled to match the rotation speed of the impeller 233. It should be noted that by using the impeller 233 and its matching power component as the reduction gear 23, the structure of the device body 22 can be designed as a curved shape, allowing the falling material to more naturally follow one side of the impeller 233's rotation, preventing the material from circumferentially enveloping the impeller 233 and causing it to jam.

[0073] It should be noted that the impeller 233 can be either a reduction impeller 233 or an impeller 233 with rotational damping. When processing larger quantities of material or requiring higher energy consumption, an impeller 233 with rotational damping can be used. The number of blades in the impeller 233 can be adapted to the size of the material. For example, when the material is granular, more blades can be used; when the material is in large pieces or flakes, fewer blades can be used.

[0074] The impeller 233 and its matching power components provided in this application are embodiments of the deceleration assembly 23. They utilize the material's own gravity potential energy to achieve the falling action. The rotating impeller 233 decelerates the material, avoiding the high energy consumption problem caused by gravity conveying in long-distance conveying of the vertical conveying device 2. It can also alleviate the impact damage to downstream equipment caused by the material falling too fast.

[0075] Furthermore, the power components include a motor 234, a drive wheel 235, and a driven wheel 236. The output end of the motor 234 is connected to the drive wheel 235. The drive wheel 235 is connected to the driven wheel 236 via a transmission belt 237. The driven wheel 236 is connected to the impeller 233.

[0076] like Figure 7 As shown, the power components include a motor 234 and a transmission mechanism. The transmission mechanism uses a transmission belt 237 to transmit power. The power output end of the motor 234 is connected to the driving wheel 235, and the driven wheel 236 is connected to the impeller 233. Under the power transmission of the driving wheel 235, driven wheel 236, and transmission belt 237, the motor 234 drives the impeller 233 to rotate. It should be noted that the motor 234, driving wheel 235, driven wheel 236, and transmission belt 237 are installed outside the device body 22, while the impeller 233 is installed inside the device body 22 and is sealed to the device body 22. The motor 234 is preferably a variable frequency motor 234. By constantly controlling the rotational speed of the impeller 233, the material conveying speed is forcibly controlled as it passes through the impeller 233, achieving a deceleration effect. The variable frequency motor 234's variable frequency adjustability can effectively control the material conveying speed, and also makes the vertical conveying device 2 of this device applicable to production lines with different processing capacity requirements, thus improving the versatility of the vertical conveying device 2.

[0077] Furthermore, the device body 22 has a first inspection port 221, the position of which corresponds to the installation position of the impeller 233. The first inspection port 221 is covered by a cover plate 224, which is structurally matched with the first inspection port 221. The cover plate 224 is connected to the device body 22 by a second fastener 222, and a first sealing ring 223 is provided between the cover plate 224 and the device body 22.

[0078] To facilitate equipment maintenance and troubleshooting of the impeller 233, the device body 22 has a first inspection port 221. The installation position of the impeller 233 corresponds to the position of the first inspection port 221, so that the impeller 233 can be better maintained, inspected, repaired, or even replaced when equipment maintenance or malfunction occurs. To ensure the sealing of the device body 22, such as... Figure 8As shown, cover plate 224 is installed over the first inspection port 221. The structure of cover plate 224 matches the structure of the first inspection port 221 and the impeller 233. Cover plate 224 is connected to device body 22 by second fastener 222. The second fastener 222 can be a bolt connection. A first sealing ring 223 is added between cover plate 224 and device body 22 to increase the sealing performance of device body 22.

[0079] Furthermore, the vertical conveying device 2 also includes a housing 231 and a protective cover 232. One end of the protective cover 232 is connected to the housing 231, and the other end is connected to the device body 22. The housing 231 houses the motor 234, and the protective cover 232 houses the drive wheel 235, the transmission belt 237, and the driven wheel 236.

[0080] like Figure 2 and Figure 7 As shown, the vertical conveying device 2 is also equipped with a housing 231 and a protective cover 232. The housing 231 is used to install and protect the motor 234. The protective cover 232 is used to protect the transmission mechanism of the impeller 233, namely the drive wheel 235, the transmission belt 237, and the driven wheel 236. The protective cover 232 is connected to the housing 231 and the device body 22, improving the compactness of the entire structure. In addition, in order to facilitate the adjustment and maintenance of the motor 234, the housing 231 is also provided with a maintenance door 238. When the motor 234 needs to be adjusted in speed or needs maintenance, the maintenance door 238 can be opened to enter the housing 231 to operate the motor 234.

[0081] Furthermore, the discharge section 24 is a flexible section, and a second support plate 245 extends radially away from the device body 22 from the discharge section 24. The bearing assembly 242 is connected to the device body 22 through the second support plate 245.

[0082] The discharge section 24 is designed as a flexible section, made of a deformable material to ensure a sealed connection with the device body 22. Specifically, the flexible section can be made of a high-strength, corrosion-resistant, and long-service-life elastic material, such as TPEE (linear thermoplastic elastomer) or neoprene rubber. The flexible section can absorb some of the vibrations that may occur during the operation of the device body 22 and downstream equipment. The flexible discharge section 24 improves the sealing performance of the connection between the device body 22 and downstream equipment.

[0083] like Figure 2 As shown, a second support plate 245 extends outward from the discharge section 24. The second support plate 245 serves as a connector between the load-bearing component 242 and the device body 22, thus connecting the two. One side of the second support plate 245 is connected to the device body 22, and the lower part of the other side is connected to the load-bearing component 242. The second support plate 245 transmits the operating vibration of the device body 22 to the load-bearing component 242, where the vibration is dissipated.

[0084] Furthermore, the support assembly 242 includes a pair of elastic element seats 2421 and a second elastic element 2422 connected between the elastic element seats 2421. The elastic element seats 2421 are sleeved on the support rod 2423. The support rod 2423 is fixedly connected to one of the elastic element seats 2421. The elastic element seat 2421 near the device body 22 is fixedly connected to the second support plate 245.

[0085] The elastic load-bearing component 242 is one embodiment of the load-bearing component 242 structure, in which, as... Figure 9 As shown, the smallest unit of the bearing assembly 242 consists of two elastic element seats 2421, one second elastic element 2422, and one support rod 2423. A second elastic element 2422 connects the two elastic element seats 2421. The support rod 2423 passes through the second elastic element 2422 and the two elastic element seats 2421. The support rod 2423 is fixedly connected to one of the elastic element seats 2421, and can be either not connected to or slidably connected to the other elastic element seat 2421. This ensures that when the two elastic element seats 2421 move relative to each other, the support rod 2423 remains stationary, acting as a limiter and fixator for the elastic element seats 2421, preventing lateral displacement of the second elastic element 2422. The bearing assembly 242 can be composed of multiple smallest units, such as... Figure 3 As shown, the bearing component 242 consists of four minimum units. The specific number of minimum units in the bearing component 242 is not limited here, but it is appropriate that the bearing component 242 can support and absorb the vibration energy of the device body 22 during operation.

[0086] like Figure 2 As shown, the elastic element seat 2421 near the device body 22, i.e., the elastic element seat 2421 located at the top in the figure, is fixedly connected to the second support plate 245. The vibration generated by the operation of the device body 22 is transmitted to the second support plate 245, and then to the elastic element seat 2421 connected to the second support plate 245. The vibration energy is absorbed and dissipated by the second elastic element 2422. The second elastic element 2422 can be a load-bearing spring. The load-bearing spring uses its elastic deformation to absorb and store energy, and then releases it smoothly, thereby bearing the load and buffering the vibration. The load-bearing spring can withstand pressure and can also mitigate external impacts through deformation.

[0087] Furthermore, the vertical conveying device 2 also includes a fixed frame 25, an elastic element seat 2421 located away from the device body 22 is fixedly connected to the fixed frame 25, and a support rod 2423 is fixedly connected to one of the fixed frame 25 and the second support plate 245.

[0088] The vertical conveying device 2 is also equipped with a fixing frame 25, which can be installed on the ground or a wall. The function of the fixing frame 25 is to bear the weight and transmit vibration to the ground. Specifically, such as Figure 2 and Figure 9 As shown, the elastic element seat 2421 (i.e., the elastic element seat 2421 below) that is away from the device body 22 is fixedly connected to the fixing frame 25. This fixed connection can be either welded or bolted.

[0089] It should be noted that the support rod 2423 can be fixed to the fixing frame 25 or the second support plate 245. For example, the support rod 2423 is fixedly connected to the fixing frame 25, and the support rod 2423 is fixedly connected to both the lower elastic element seat 2421 and the fixing frame 25. The support rod 2423 passes through the upper elastic element seat 2421 and the second support plate 245. The support rod 2423 can be unconnected to the upper elastic element seat 2421 and the second support plate 245, or it can be slidably connected, as long as the support rod 2423 can limit the upper elastic element seat 2421. For example, if the support rod 2423 is fixedly connected to the upper elastic element seat 2421 and the second support plate 245, then the support rod 2423 passes through the lower elastic element seat 2421 and the fixing frame 25. The support rod 2423 can be either not connected to the lower elastic element seat 2421 and the fixing frame 25 or can be slidably connected, as long as the support rod 2423 can limit the lower elastic element seat 2421.

[0090] This design allows the vibration of the device body 22 during operation to be transmitted to the bearing assembly 242 via the second support plate 245. The bearing assembly 242 dissipates the vibration. If there is any remaining vibration after passing through the bearing assembly 242, it is transmitted to the fixed frame 25, and then from the fixed frame 25 to the ground, where the ground absorbs the remaining vibration. In this design, the fixed frame supports the weight of the device body 22, allowing the device body 22 to be suspended between the upstream and downstream equipment, thus avoiding load forces at the connection interface between the vertical conveying device 2 and the upstream and downstream equipment.

[0091] It should be noted that the housing 231 of the deceleration assembly 23 can be installed on the second support plate 245. The vibration of the motor 234 is transmitted to the second support plate 245 through the housing 231, and the vibration generated by the motor 234 is dissipated by the bearing assembly 242.

[0092] Furthermore, the feeding section 21 is configured as a first corrugated pipe 212, and / or the discharge section 24 is configured as a second corrugated pipe 241. One end of the second corrugated pipe 241 is connected to the second support plate 245, the second support plate 245 is connected to the device body 22 by a third fastener 243, and the other end of the second corrugated pipe 241 has a discharge port 244.

[0093] like Figure 2and Figure 3 As shown, the flexible feed section 21 and / or discharge section 24 are configured as bellows. This means that either the feed section 21 or the discharge section 24 can be configured as a bellows, or both the feed section 21 and the discharge section 24 can be configured as bellows. The bellows can effectively seal the upstream and downstream equipment and the main body 22, and can also absorb vibrations generated by the operation of the equipment connected to both ends of the bellows. Specifically, one end of the second bellows 241 has a discharge port 244, such as... Figure 10 As shown, the second corrugated pipe 241 is connected to the second support plate 245 at one end near the device body 22. The device body 22 and the second support plate 245 are connected by a third fastener 243. The discharge port 244 facilitates the connection between the discharge section 24 and downstream equipment. The third fastener 243 can be a bolted connection. The corrugated pipe can improve the sealing of the connection between the device body 22 and the downstream equipment, and can also absorb some of the vibrations generated by the operation of the device body 22 and the downstream equipment.

[0094] It should be noted that the first corrugated pipe 212 and the second corrugated pipe 241 are respectively installed at the upper and lower ends of the device body 22. At the upper end of the device body 22, the first corrugated pipe 212 is supported by a first support plate 211 close to the device body 22. The first support plate 211 close to the device body 22 has a double-layer groove. The first corrugated pipe 212 is placed in the deeper groove, and then fastening screws are used to lock the inlet of the device body 22 and the first support plate 211 to ensure the fixation of the first corrugated pipe 212 to the device body 22. At the lower end, a double-layer groove is provided at the outlet edge of the lower end of the device body 22. The second corrugated pipe 241 is installed in the deeper groove, and the second support plate 245 is placed in the shallower groove. It is fixed with a third fastener 243 to press the second corrugated pipe 241 tightly onto the device body 22. This double-groove lamination design is beneficial for fixing the corrugated pipe, can avoid leakage of dusty materials, and can also reduce the aging risk of the corrugated pipe under high pressure environment. During equipment operation, the corrugated pipe will adaptively expand and contract according to the vibration amplitude transmitted by the device body and upstream and downstream equipment, which can effectively ensure the continuity of material conveying.

[0095] In addition, the first support plate 211 and the second support plate 245 can be a frame structure made of steel plate material, which can play a role in supporting the corrugated pipe.

[0096] like Figure 2 The diagram shows a material conveying production line, including an upper machine station 1, a lower machine station 3, and the aforementioned vertical conveying device 2. The two ends of the vertical conveying device 2 are respectively sealed to the upper machine station 1 and the lower machine station 3. The vibration damping component 213 of the vertical conveying device 2 absorbs the vibration of the upper machine station 1, and the bearing component 242 of the vertical conveying device 2 absorbs the vibration of the device body 22.

[0097] Specifically, such as Figure 1As shown, the material conveying production line includes an upper machine station 1, a vertical conveying device 2, and a lower machine station 3. The upper machine station 1 and the vertical conveying device 2 are sealed together, and the vertical conveying device 2 and the lower machine station 3 are sealed together.

[0098] like Figure 5 A first connecting plate 12 extends outward from the outlet of the upper machine position 1. The first support plate 211 of the vertical conveying device 2, which is away from the device body 22, is connected to the first connecting plate 12 by a fourth fastener 11. The fourth fastener 11 can be a bolt connection. A second sealing ring can be added between the first support plate 211 and the first connecting plate 12 to achieve a sealed connection between the upper machine position 1 and the vertical conveying device 2.

[0099] like Figure 10 As shown, the inlet of the lower unit 3 overlaps with the outlet 244 of the vertical conveying device 2. A third sealing ring can be added at the connection. The inlet of the lower unit 3 and the outlet 244 can be connected by a fifth fastener 31, which can be a bolt. Specifically, a support frame 246 can be provided on the inner wall of the outlet 244. The support frame 246 can be made of steel plate and can support the second corrugated pipe 241. The second corrugated pipe 241 is tightly connected to the lower unit 3 by the fifth fastener 31, which can prevent material leakage or external contamination.

[0100] Because the mass of material received by the impeller 233 changes continuously during operation, there may be uneven force distribution on its own mass and the attached blades. During rotation, the impeller 233 may experience dynamic imbalance and other adverse phenomena. The centrifugal force of the impeller 233 will induce periodic excitation force, causing the device body 22 to vibrate. If the device body 22 is directly fixedly connected to the upper machine position 1 without flexible feeding section 21 and discharge section 24, bending fatigue and increased wear will occur at the connection between the device body 22 and the upper and lower machine positions 3. The material conveying production line provided in this application increases the rotational and vertical translational degrees of freedom on the plane formed by the radial direction of the impeller 233's shaft through the vibration damping component 213 and the bearing component 242. The energy brought by the amplitude is absorbed by the first elastic element 2135 and the second elastic element 2422. In addition, the rotational degree of freedom can also avoid wear, fatigue fracture, and other problems that may occur at the lateral fixed connection between the upper machine position 1 and the lower machine position 3 of the material conveying production line.

[0101] The working process of the material conveying production line provided by the present invention is as follows: After the material is processed by the upper station 1 process, it falls into the vertical conveying device 2 under the action of its own gravity. The material passes through the impeller 233 set at the turning point of the device body 22. The conveying speed of the material is reduced under the drive of the impeller 233, and then it is conveyed to the lower station 3 process.

[0102] During this process, the deceleration component 23 of the impeller 233 structure will generate a lot of vibration, which is absorbed by the bearing component 242. The bellows will expand and contract adaptively with the vibration amplitude to ensure smooth material flow.

[0103] After being processed at the upper station 1, the material falls freely along the feed section 21 into the main body 22 under gravity. As the material flows through the impeller 233 of the main body 22, the centrifugal force field generated by the impeller 233 reconstructs the material's trajectory, causing its conveying speed to decrease. During this dynamic conveying process, the impact between the impeller 233 and the material excites mechanical vibration in the main body 22. This vibration energy is dissipated and attenuated by the elastic damping structure of the bearing component 242, effectively suppressing the transmission of vibration to the upper station 1 and lower station 3. Furthermore, the bellows connecting the upper station 1 and lower station 3, based on its elastic deformation characteristics, adaptively adjusts its axial length according to the vibration amplitude. This maintains the integrity of the sealing interface and ensures the unobstructed flow of material in and out of the channels, achieving high stability and low interference in the conveying process.

[0104] The material conveying production line provided in this application has a vertical conveying device whose inlet is in direct contact with the upper machine position 1 and whose outlet is in direct contact with the lower machine position 3. This reduces the space ratio of the vertical conveying device 2, improves the utilization rate of vertical space in the production line, and avoids the need for additional pipelines.

[0105] In addition, the material conveying production line system provided in this application is simple, easy to operate, saves space, and is easy to industrialize.
