Description

Technical Field

[0001] This utility model relates to the technical field of powder recycling devices, and in particular to a dual-cyclone separation type powder recycling and reuse device. Background Technology

[0002] During the processing of powder materials, a large number of incompletely utilized powder particles are generated. Efficient recycling and reuse of these powders can not only reduce raw material costs, but also reduce resource waste and control dust pollution. The dual-cyclone separation powder recycling and reuse device is the core equipment designed to meet this need. It achieves efficient graded recycling of powders through the synergistic effect of the dual-stage cyclone separation structure.

[0003] The dust-laden airflow first enters the primary cyclone separation unit. Through the centrifugal force generated by high-speed rotation, large-diameter powder particles are thrown against the inner wall of the separator due to inertia and fall down the wall to the powder collection bin, completing the initial coarse separation. Fine particles that are not completely captured by the primary separation unit enter the secondary cyclone separation unit with the airflow. They are further separated by a finer rotating flow field. The fine powder eventually settles into the secondary powder collection bin, while the purified clean airflow is discharged from the top exhaust port.

[0004] In the practical application of existing dual-cyclone separation powder recovery devices, when the powder collection bin completes powder collection and reaches the capacity threshold, the powder collection bin needs to be unloaded and recovered. However, the discharge port of the current device is often in an unrestrained open state during this process, which causes the fine powder remaining in the separator to fall unexpectedly due to gravity. This phenomenon not only increases the complexity of the secondary collection operation, but may also cause additional loss of powder resources. Therefore, this application proposes a dual-cyclone separation powder recovery and reuse device. Utility Model Content

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figures 1-3As shown, this utility model proposes a dual-cyclone separation type powder recycling and reuse device, including a separator 1. Powder is separated by the separator 1. The separator 1 is a common and mature device in existing powder processing and separation, and will not be described in detail. A support 2 is fixedly connected to the outside of the separator 1, which supports the separator 1. The device also includes a flexible tube 3 sleeved at the bottom of the separator 1. Under the action of gravity, the separated powder falls into the inside of the flexible tube 3 through the discharge port at the bottom of the separator 1. A pipe clamp 4 is installed on the outside of the flexible tube 3. The pipe clamp 4 is existing technology and can be fixed to the outside of the separator 1 for easy disassembly. An installation chamber 5 is fixedly connected to the bottom of the flexible tube 3. The powder then falls into the inside of the installation chamber 5 through the flexible tube 3. The end of the installation chamber 5 away from the flexible tube 3 is fixedly connected to the outside of the separator 1. A powder collection chamber 6 is slidably connected inside the installation chamber 5. Finally, the powder will accumulate inside the powder collection chamber 6.

[0030] Furthermore, such as Figure 2 and Figure 3 As shown, there are at least two symmetrically distributed clamping plates 7. A pair of limiting rods 8 are slidably connected inside the clamping plates 7. Support plates 9 are fixed to both ends of the pair of limiting rods 8. The support plates 9 are fixed to the outside of the separator 1. The support plates 9 can support the limiting rods 8 and the clamping plates 7, so that the two clamping plates 7 are symmetrically distributed on both sides of the hose 3.

[0031] Among them, such as Figure 3 As shown, this embodiment also includes a pressing mechanism disposed around the periphery of the card plate 7, which works in conjunction with the powder collection bin 6 to restrict the position of the card plate 7. When the powder collection bin 6 is inside the installation bin 5, the pressing mechanism will drive a pair of card plates 7 to be in a state away from the hose 3, so that the internal channel of the hose 3 can normally transport powder to the inside of the powder collection bin 6. When the powder collection bin 6 moves out of the installation bin 5, the pressing mechanism will drive the card plates 7 to press the hose 3. The hose 3 will then be deformed by force, sealing its internal channel. At this time, the powder cannot pass through the hose 3 smoothly, thus avoiding the powder remaining inside the separator 1 still being scattered when the powder collection bin 6 moves out of the installation bin 5. Through the above structural design, the movement of the powder collection bin 6 can control the opening and closing of the internal channel of the card plate 7.

[0032] In addition, such as Figure 4 As shown, the linkage mechanism is set on the periphery of the card plate 7 to control the synchronous movement of a pair of card plates 7. When one card plate 7 moves, the linkage mechanism will run, thereby controlling the other card plate 7 to move synchronously. The two card plates 7 move in opposite directions, ensuring that the two card plates 7 can squeeze the hose 3 at the same time, or release the squeeze on the hose 3 at the same time.

[0033] It should be noted that, as Figure 3As shown, the extrusion mechanism includes a guide rod 10 and two pairs of springs 11. The extrusion mechanism is described in detail below:

[0034] The guide rod 10 is located inside the installation chamber 5. The end of the guide rod 10 away from the installation chamber 5 is fixedly connected to the clamping plate 7. In the initial state, the powder collection chamber 6 is inside the installation chamber 5, which puts pressure on one end of the guide rod 10. Two pairs of springs 11 are respectively sleeved on the outside of a pair of limiting rods 8. The two ends of the two pairs of springs 11 are respectively fixedly connected to the clamping plate 7 and the support plate 9. When one end of the guide rod 10 is subjected to the squeezing force from the powder collection chamber 6, the guide rod 10 will pull the clamping plate 7 close to the guide rod 10 to move. The clamping plate 7 then puts pressure on the springs 11. When the powder collection chamber 6 moves out of the installation chamber 5, the pulling of the guide rod 10 on the clamping plate 7 ends, and the springs 11 will release elastic potential energy, thereby pushing the clamping plate 7 closer to the hose 3, fixing the hose 3 and sealing the internal channel of the hose 3 to prevent powder from scattering.

[0035] In addition, such as Figure 4 As shown, the linkage mechanism includes a pair of racks 12, a spur gear 13, and a connecting rod 14. The linkage mechanism is described in detail below:

[0036] A pair of racks 12 are fixedly connected to the outer sides of two clamping plates 7 respectively. When the clamping plates 7 move, they will drive the fixed racks 12 to move. The two sides of the spur gear 13 are respectively engaged with the pair of racks 12. When one clamping plate 7 moves, the clamping plate 7 will drive the spur gear 13 to rotate. The rotation of the spur gear 13 will drive the other clamping plate 7 to move relative to it, thereby achieving the purpose of synchronous movement of the two clamping plates 7. The connecting rod 14 is rotatably connected to the inside of the spur gear 13. The end of the connecting rod 14 away from the spur gear 13 is fixedly connected to the outer side of the separator 1. The connecting rod 14 can support the position of the spur gear 13.

[0037] Furthermore, such as Figure 3 and Figure 5 As shown, a locking mechanism is provided on the outside of the installation chamber 5. The locking mechanism is used to restrict the position of the powder collection chamber 6. When the powder collection chamber 6 moves into the interior of the installation chamber 5, the locking mechanism can lock the position of the powder collection chamber 6, thereby avoiding the situation where the position of the powder collection chamber 6 is offset due to the elastic effect of the spring-11 and the guide rod 10 squeezed by the locking plate 7, so that the powder collection chamber 6 is more stable when it is inside the installation chamber 5.

[0038] Among them, such as Figure 5 As shown, the engaging mechanism includes a pull rod 15, a side plate 16, a locking rod 17, a locking groove 18, a pair of limiting rods 19, a fixing plate, and a spring 20. The engaging mechanism is described in detail below:

[0039] The side plate 16 is fixedly connected to the pull rod 15. Pulling the pull rod 15 can move the side plate 16. The locking rod 17 is fixedly connected to the end of the side plate 16 away from the pull rod 15. When the side plate 16 moves, it will move the locking rod 17. The locking groove 18 is opened on the outside of the powder collection chamber 6. The locking rod 17 is located inside the locking groove 18. When the locking rod 17 moves, it will disengage from the inside of the locking groove 18. At this time, the locking rod 17 stops limiting the powder collection chamber 6, and the powder collection chamber 6 can be moved out of the installation chamber 5. The pair of limiting rods 19 are both fixedly connected to the outside of the installation chamber 5. The limiting rods 19 penetrate the side plate 16. The pair of limiting rods 19 can limit the side plate 16. The side plate 16 acts as a limit, allowing it to move only laterally. The fixed plate is fixed to the end of a pair of limit rods 19 away from the installation chamber 5. The two ends of the pair of springs 20 are fixed to the side plate 16 and the fixed plate, respectively. When the side plate 16 moves away from the powder collection chamber 6, it will also work with the fixed plate to compress the springs 20, causing them to deform and generate elastic potential energy. When the powder collection chamber 6 is back inside the installation chamber 5, the elastic potential energy released by the springs 20 can drive the locking rod 17 back into the slot 18 through the side plate 16, thus limiting the powder collection chamber 6 again.

[0040] Furthermore, such as Figure 3 and Figure 4 As shown, an arc-shaped plate 21 is glued to one end of each pair of clamping plates 7. The pair of arc-shaped plates 21 are symmetrically distributed. The arrangement of the pair of arc-shaped plates 21 can reduce the contact area when the clamping plates 7 squeeze the hose 3, thereby increasing the local pressure and making the squeezing force applied to the hose 3 greater, thus improving the sealing performance of the hose 3 when it is closed.

[0041] In addition, such as Figure 5 As shown, the powder collection chamber 6 is provided with an inclined block 22 inside. The inclined block 22 is fixedly connected to the inner wall of the powder collection chamber 6. When the powder falls, it will be at the top of the inclined surface of the inclined block 22. At this time, when the powder comes into contact with the inclined block 22, it will accumulate along the inclined surface of the inclined block 22, which avoids the fixed landing point of the powder each time, and prevents the powder from accumulating in a single position inside the powder collection chamber 6.

[0042] In addition, such as Figure 5 As shown, a handle 23 is fixedly connected to the outside of the powder collection bin 6. A rubber pad 24 is glued to the outside of the handle 23. When pulling the powder collection bin 6, it can be pulled by the handle 23, which is more convenient. The rubber pad 24 can increase the friction between the hand and the handle 23 and also play a buffering role, making it more comfortable for the hand to pull the handle 23.

[0043] In this embodiment, the powder is separated by separator 1. Under the action of gravity, the separated powder falls into the inside of hose 3 through the feed port at the bottom of separator 1. The powder then falls into the inside of installation chamber 5 through hose 3. Finally, the powder accumulates inside powder collection chamber 6. In the initial state, powder collection chamber 6 is inside installation chamber 5, which puts one end of guide rod 10 under pressure. When one end of guide rod 10 is subjected to the pressure from powder collection chamber 6, guide rod 10 will pull the card plate 7 close to guide rod 10 to move. Card plate 7 is in a state of compression on spring 11. When powder collection chamber 6 moves out of installation chamber 5, the pulling of guide rod 10 on card plate 7 ends, and spring 11 will release elastic potential energy, thereby pushing card plate 7 close to hose 3 to fix hose 3 and seal the internal channel of hose 3. When one card plate 7 moves, card plate 7 will drive spur gear 13 to rotate. The rotation of spur gear 13 will drive the other card plate 7 to move relative to it, thereby achieving the purpose of synchronous movement of the two card plates 7.

[0044] Pulling the lever 15 can move the side plate 16. When the side plate 16 moves, it will move the locking lever 17. When the locking lever 17 moves, it will disengage from the inside of the locking groove 18. At this time, the locking lever 17 ends its limiting of the powder collection chamber 6, and the powder collection chamber 6 can be moved out of the inside of the installation chamber 5. When the side plate 16 moves away from the powder collection chamber 6, the side plate 16 will also work with the fixing plate to compress the second spring 20, causing the second spring 20 to deform and generate elastic potential energy. When the powder collection chamber 6 is back inside the installation chamber 5, the elastic potential energy released by the second spring 20 can drive the locking lever 17 back into the inside of the locking groove 18 through the side plate 16.

[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
