Description

Technical Field

[0001] This application relates to the field of raw material conveying technology, and in particular to a folded discharge pipe for a silo. Background Technology

[0002] A mineral powder raw material intermediate silo is a storage silo used to store mineral powder raw materials. It is a large piece of equipment commonly used in the building materials industry. During the transfer of mineral powder raw materials, the transfer vehicle is driven to the bottom of the silo's discharge pipe. When the receiving port of the transfer vehicle is aligned with the outlet of the discharge pipe, the valve is opened, allowing the product in the silo to enter the transport vehicle along the discharge pipe.

[0003] In powder warehouses, due to the movement requirements of transfer vehicles and changes in vehicle load, a dynamic height difference must be reserved between the outlet of the discharge pipe and the vehicle receiving port. However, existing discharge pipes are usually fixed, and the height of the discharge pipe opening is fixed and cannot be extended or retracted. During the feeding process, after the powder leaves the discharge pipe, it is easy for it to fall freely to the outside, causing the powder to drift in the warehouse and unable to enter the transfer vehicle for transfer, resulting in waste of powder raw materials, which is obviously insufficient. Utility Model Content

[0004] To reduce waste of powder raw materials during the transfer process, this application provides a folded discharge pipe for a silo.

[0005] The technical solution provided in this application for a folded discharge pipe for a silo is as follows:

[0006] A folded discharge pipe for a hopper includes a support frame, on which a hopper is mounted, and a discharge pipe is connected to the outlet of the hopper. The support frame has an opening for the discharge pipe to pass through. A compression pipe, which is a telescopic flexible pipe, is mounted at the end of the discharge pipe away from the discharge pipe. A connecting ring is fixedly sleeved on the end of the compression pipe away from the discharge pipe. The support frame is provided with a drive assembly that drives the connecting ring to move along the length of the discharge pipe.

[0007] By adopting the above technical solution, when the receiving port of the transfer vehicle moves to below the discharge pipe, the drive component drives the connecting ring to move towards the transfer vehicle. The movement of the connecting ring drives the compression pipe to enter the interior of the transfer vehicle through the receiving port. At this time, the valve is opened, and the powder raw material directly enters the interior of the transfer vehicle after separating from the discharge pipe and the compression pipe, thereby reducing the waste of raw materials caused by powder overflow. The setting of the drive component realizes the adjustment of the height distance between the discharge pipe outlet and the receiving port of the transfer vehicle, effectively avoiding dust waste caused by height difference, thereby reducing the waste of powder raw materials during the transfer process.

[0008] Optionally, the drive assembly includes multiple winding reels rotatably connected to the support frame, each winding reel having a steel wire rope wound on it. The ends of the multiple steel wire ropes are provided with a common mounting ring, which is sleeved on the outer surface of the connecting ring. Each winding reel has a driven gear coaxially arranged on it. A drive gear ring meshing with the driven gear is rotatably connected to the support frame. A drive motor is provided on the support frame, and the output shaft of the drive motor has a drive gear meshing with the drive gear ring.

[0009] By adopting the above technical solution, the drive motor drives the drive gear to rotate, the drive gear drives the drive gear ring to rotate on the support frame, and the drive gear ring drives multiple winding discs to rotate synchronously through the meshing driven gear, thereby realizing the synchronous winding and unwinding of the wire rope. During the winding and unwinding process, the wire rope pulls the connecting ring to rise and fall along the length of the discharge pipe, thus realizing the height adjustment between the discharge pipe outlet and the material receiving port of the transfer vehicle. At the same time, the setting of the drive component realizes the synchronous rotation of multiple winding discs, ensuring that the wire rope is wound and unwinded at the same rate, thereby ensuring the force balance of the connecting ring in different directions and ensuring the smooth extension and retraction of the compression pipe.

[0010] Optionally, the inlet of the compression pipe is detachably connected to the outlet pipe via a flange, and the mounting ring is detachably mounted on the connecting ring via multiple connecting components.

[0011] By adopting the above technical solution, workers can separate or connect the compression pipe and the discharge pipe by disassembling and assembling the flange, and then separate or connect the compression pipe and the mounting ring by connecting components, thereby realizing the replacement of the compression pipe. This realizes the modular replacement of the compression pipe, which makes it easier for workers to replace the damaged compression pipe in a timely manner and improves the convenience of workers during maintenance.

[0012] Optionally, a plurality of the connecting components are evenly and equidistantly arranged on the outer surface of the mounting ring in the circumferential direction. Each connecting component includes a limiting block. The mounting ring has a limiting groove that slides with the limiting block. The inner wall of the limiting groove has a sliding groove. The end of the limiting block is provided with a plug-in stud that slides with the sliding groove. The connecting ring has a threaded groove that threads with the plug-in stud. When the plug-in stud passes through the sliding groove and is threaded into the threaded groove, the end face of the limiting block abuts against the inner wall of the limiting groove.

[0013] By adopting the above technical solution, when separating the compression tube and the mounting ring, the worker rotates the limiting block in sequence. The limiting block drives the plug stud to rotate and unscrew out of the threaded groove. After all the plug studs are disassembled, the mounting ring is separated from the compression tube. When connecting the compression tube and the mounting ring, the user inserts the plug stud into the sliding groove, and then rotates the limiting block to screw the threaded section of the plug stud into the threaded groove. After all the plug studs are installed, the mounting ring is connected to the compression tube.

[0014] Optionally, guide strips are provided on both opposite sides of the connecting ring, and a guide groove is provided on the inner sidewall of the mounting ring to slide with the guide strip. When the guide strip slides inside the guide groove, the sliding groove communicates with the threaded groove.

[0015] By adopting the above technical solution, during the process of connecting the compression pipe and the connecting ring, the worker can achieve precise alignment of the sliding groove and the threaded groove by inserting the guide strip into the guide groove. This eliminates the need for the worker to spend a lot of time aligning the sliding groove and the threaded groove, and avoids installation difficulties or loose connections caused by positional deviations, thus improving the convenience for workers when installing the compression pipe.

[0016] Optionally, a guide pipe is provided at the outlet of the compression pipe. The guide pipe is conical and its diameter gradually decreases along the powder conveying path.

[0017] By adopting the above technical solution, the conical guide tube plays a role in gathering and guiding the powder, so that the originally dispersed powder flow can be concentrated and transported towards the transfer vehicle, thereby further reducing the scattering and splashing of powder and reducing the waste of powder during the transfer process.

[0018] Optionally, the outer surface of the flange is provided with guide sleeves corresponding to the plurality of wire ropes, and the wire ropes are threaded through the corresponding guide sleeves.

[0019] By adopting the above technical solution, the guide sleeve allows the wire rope to move only in the vertical direction during the winding and unwinding process, avoiding the problem of the wire rope deviating during the movement. This ensures that the wire rope pulls the compression tube along the predetermined trajectory. At the same time, the guide sleeve plays a supporting and fixing role for the wire rope, reducing the swaying amplitude of the wire rope during the movement and improving the stability of the compression tube during the extension and retraction process.

[0020] Optionally, a spiral guide plate is provided on the inner wall of the guide pipe, and the spiral direction of the spiral guide plate is parallel to the length direction of the discharge pipe.

[0021] By adopting the above technical solution, the powder flows along a spiral path in the guide tube, thereby making the powder distribution in the guide tube more uniform. This avoids the local accumulation of powder or the formation of eddies at the end of the guide tube with a smaller diameter, so that the powder can be discharged from the outlet at a relatively stable speed and in a uniform state, thus improving the quality and stability of the output.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this embodiment of the application, by setting up a drive component and a compression pipe, when the receiving port of the transfer vehicle moves to below the discharge pipe, the drive component drives the connecting ring to move towards the transfer vehicle. The movement of the connecting ring drives the compression pipe to enter the interior of the transfer vehicle through the receiving port. At this time, the valve is opened, and the powder raw material directly enters the interior of the transfer vehicle after separating from the discharge pipe and the compression pipe, thereby reducing the waste of raw materials caused by powder overflow. The setting of the drive component realizes the adjustment of the height distance between the discharge pipe outlet and the receiving port of the transfer vehicle, effectively avoiding dust waste caused by height difference, thereby reducing the waste of powder raw materials during the transfer process.

[0024] 2. In this embodiment of the application, by setting up a connecting component and a flange, workers can separate or connect the compression pipe and the discharge pipe by disassembling and assembling the flange. Then, the connecting component is used to separate or connect the compression pipe and the mounting ring, thereby realizing the replacement of the compression pipe. This realizes the modular replacement of the compression pipe, which makes it easier for workers to replace the damaged compression pipe in a timely manner and improves the convenience of workers during maintenance.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0030] This application discloses a folded discharge pipe for a silo.

[0031] Reference Figure 1 and Figure 2 A folding discharge pipe for a silo includes a support frame 1, which is installed inside the silo. A silo 01 containing powdered raw materials is fixedly installed inside the support frame 1. A discharge pipe 2 is connected to the outlet of the silo 01. An opening 101 for the discharge pipe 2 to extend out is provided on the support frame 1.

[0032] Reference Figure 1 and Figure 2 The end of the discharge pipe 2 is detachably connected to a compression pipe 3. The compression pipe 3 and the discharge pipe 2 are detachably connected by a flange 4. The compression pipe 3 is a telescopic flexible pipe. A connecting ring 31 is fixedly sleeved on the outer surface of the end of the compression pipe 3 away from the discharge pipe 2.

[0033] Reference Figure 1 and Figure 2 The support frame 1 is provided with a drive assembly 5. Specifically, the drive assembly 5 includes a plurality of winding reels 51 rotatably connected to the support frame 1. The plurality of winding reels 51 are evenly distributed equidistantly on the outer periphery of the discharge pipe 2. In this embodiment, the number of winding reels 51 is three, and each winding reel 51 is wound with a steel wire rope 52.

[0034] Reference Figure 1 and Figure 2 The outer surface of the flange 4 is fixedly connected with guide sleeves 41 corresponding to the three steel wire ropes 52. The guide sleeves 41 are parallel to the length direction of the discharge pipe 2. The end of each steel wire rope 52 passes through the opening 101 and through the corresponding guide sleeve 41. The ends of the three steel wire ropes 52 are fixedly connected with an installation ring 53. The installation ring 53 is sleeved on the outer surface of the connecting ring 31 and is detachably connected to the connecting ring 31 through the connecting component 6.

[0035] Reference Figure 1 and Figure 2 Each winding reel 51 has its axial direction parallel to the radial direction of the discharge pipe 2. Each winding reel 51 has a driven gear 54 coaxially fixedly connected to the end away from the opening 101. A drive gear ring 55 meshing with the driven gear 54 is rotatably connected to the support frame 1. A drive motor 56 is fixedly installed on the support frame 1. The output shaft of the drive motor 56 is coaxially fixedly connected to a drive gear 57 meshing with the drive gear ring 55. The drive gear 57 drives the drive gear ring 55 to rotate, thereby realizing the synchronous rotation of multiple driven gears 54 driving multiple winding reels 51, ensuring that the wire rope 52 is wound and unwound at the same speed, thus ensuring the force balance of the connecting ring 31 in different directions.

[0036] When the receiving port of the transfer vehicle moves to below the discharge pipe 2, the drive motor 56 drives the drive gear 57 to rotate in the forward direction. The drive gear 57 drives the drive gear ring 55 to rotate in the forward direction on the support frame 1. The drive gear ring 55 drives multiple winding discs 51 to rotate in the forward direction synchronously through the driven gear 54. During the rotation of the winding discs 51, the wire rope 52 is loosened, and the tension of the wire rope 52 on the connecting ring 31 is reduced. The connecting ring 31 drives the compression pipe 3 to extend downward along the axis of the discharge pipe 2. When the outlet of the compression pipe 3 enters the interior of the transfer vehicle, the valve opens. After the powder raw material leaves the discharge pipe 2 and the compression pipe 3, it directly enters the interior of the transfer vehicle, thereby reducing the waste of raw materials caused by the overflow of powder.

[0037] After the transfer vehicle finishes collecting, the valve closes, and the drive motor 56 drives the drive gear 57 to rotate in the opposite direction. The drive gear 57 drives multiple winding discs 51 to rotate in the opposite direction synchronously through the meshing action of the drive gear ring 55 and the driven gear 54. The winding discs 51 tighten the wire rope 52, and the wire rope 52 pulls the connecting ring 31 to move upward. At this time, the compression tube 3 gradually contracts to the initial position.

[0038] Reference Figure 2 and Figure 3 Multiple connecting components 6 are evenly and equidistantly arranged on the outer surface of the mounting ring 53 along the circumferential direction. In this embodiment, the number of connecting components 6 is six. Each connecting component 6 includes a limiting block 61. The mounting ring 53 has a limiting groove 531 that slides with the limiting block 61. The inner wall of the limiting groove 531 is connected to a sliding groove 532. The end of the limiting block 61 is fixedly connected to a plug-in stud 62 that slides with the sliding groove 532. The connecting ring 31 has a threaded groove 311 that corresponds one-to-one with the multiple limiting grooves 531. The threaded groove 311 is connected to the corresponding limiting groove 531. The length direction of the limiting groove 531 and the threaded groove 311 is parallel to the radial direction of the discharge pipe 2. When the plug-in stud 62 passes through the sliding groove 532 and is threaded into the threaded groove 311, the end face of the limiting block 61 abuts against the inner wall of the limiting groove 531.

[0039] Reference Figure 2 and Figure 3 Guide bars 312 are fixedly connected to the outer surfaces of the connecting ring 31. The inner wall of the mounting ring 53 is provided with a guide groove 533 that slides with the guide bar 312. When the guide bar 312 slides inside the guide groove 533, the sliding groove 532 communicates with the corresponding threaded groove 311.

[0040] When the compression pipe 3 becomes unusable due to wear, the worker first separates the compression pipe 3 from the discharge pipe 2 by disassembling the flange 4. Then, the worker rotates the limiting block 61 in sequence. The limiting block 61 drives the plug stud 62 to rotate and unscrew the threaded groove 311. After all the plug studs 62 have been disassembled, the fixing effect of the connecting component 6 on the connecting ring 31 disappears. The worker then disassembles the compression pipe 3 by pulling the connecting ring 31 downward.

[0041] When installing a new compression pipe 3, the worker first inserts the guide strip 312 into the guide groove 533. The guide strip 312 and the guide groove 533 guide and match the sliding groove 532 and the threaded groove 311. Then, the worker inserts multiple plug-in studs 62 into the sliding groove 532. Next, the worker rotates the limiting block 61 in sequence so that the threaded section of the plug-in stud 62 is screwed into the threaded groove 311. After all the plug-in studs 62 are installed, the installation ring 53 is connected to the compression pipe 3. Finally, the worker connects the compression pipe 3 to the discharge pipe 2 through the flange 4. This completes the installation of the compression pipe 3 and enables modular replacement of the compression pipe 3. This makes it easier for workers to replace damaged compression pipes 3 in a timely manner and improves the convenience of maintenance.

[0042] Reference Figure 2 and Figure 3 A guide pipe 7 is fixedly connected to the outlet of the compression pipe 3. The guide pipe 7 is coaxially arranged with the outlet pipe 2. The guide pipe 7 is conical and its diameter gradually decreases along the powder conveying path. A spiral guide plate 71 is fixedly connected to the inner wall of the guide pipe 7. The spiral direction of the spiral guide plate 71 is parallel to the length direction of the outlet pipe 2.

[0043] When the powder flows into the guide pipe 7, it flows along a spiral path within the guide pipe 7, making the powder distribution more uniform. At the same time, the conical guide pipe 7 plays a role in gathering and guiding the powder, allowing the originally dispersed powder flow to be concentrated and transported towards the transfer vehicle, thereby further reducing powder scattering and splashing, and reducing powder waste during the transfer process.

[0044] The implementation principle of a folded discharge pipe for a silo in this application embodiment is as follows: When the receiving port of the transfer vehicle moves to below the discharge pipe 2, the drive motor 56 drives the drive gear 57 to rotate in the forward direction. The drive gear 57 drives the drive gear ring 55 to rotate in the forward direction on the support frame 1. The drive gear ring 55 drives multiple winding discs 51 to rotate in the forward direction synchronously through the driven gear 54. During the rotation of the winding discs 51, the wire rope 52 is loosened, and the tension of the wire rope 52 on the connecting ring 31 is reduced. The connecting ring 31 drives the compression pipe 3 to extend downward along the axis of the discharge pipe 2. When the outlet of the compression pipe 3 enters the interior of the transfer vehicle, the valve is opened. After the powder raw material leaves the discharge pipe 2 and the compression pipe 3, it directly enters the interior of the transfer vehicle, thereby reducing the waste of raw materials caused by the overflow of powder.

[0045] After the transfer vehicle finishes collecting, the valve closes, and the drive motor 56 drives the drive gear 57 to rotate in the opposite direction. The drive gear 57 drives multiple winding discs 51 to rotate in the opposite direction synchronously through the meshing action of the drive gear ring 55 and the driven gear 54. The winding discs 51 tighten the wire rope 52, and the wire rope 52 pulls the connecting ring 31 to move upward. At this time, the compression tube 3 gradually contracts to the initial position.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
