Description

Technical Field

[0001] This application relates to the field of centrifuge equipment, and in particular to a centrifuge unloading structure. Background Technology

[0002] Centrifuges are solid-liquid separation equipment widely used in chemical, pharmaceutical, food and environmental protection fields. Their discharge port is often connected to downstream equipment, such as collection hoppers and storage containers, through pipelines.

[0003] Currently, in the vertical layout of factories, centrifuges are usually located on the upper floors, while back-end equipment is located on the floors below them. The two floors are connected by openings to facilitate the docking and communication between the centrifuges and the back-end equipment. The height difference allows the solid material in the centrifuge to be discharged from the centrifuge and quickly enter the back-end equipment for processing. The discharge port of the existing centrifuge is usually a flange pipe fixed on the centrifuge. In the actual docking process, the centrifuge is usually placed in the corresponding position first, and then the back-end equipment is moved below the centrifuge discharge port. After initial alignment, external auxiliary tools, such as pry bars, are used to make fine adjustments to ensure that the bolt holes on the flange of the centrifuge discharge port correspond one-to-one with the bolt holes on the flange of the back-end equipment inlet, thereby realizing the connection between the centrifuge and the back-end equipment.

[0004] However, because the positions of each bolt hole need to be aligned one by one, the positional accuracy of the back-end equipment is required to be high. Therefore, the installers often need to make repeated adjustments, resulting in low installation efficiency of the centrifuge. Summary of the Invention

[0005] To improve the installation efficiency of centrifuges, this application provides a centrifuge unloading structure.

[0006] The centrifuge unloading structure provided in this application adopts the following technical solution: It includes a feed pipe, a telescopic discharge pipe, and a connecting pipe. The feed pipe is located at and connected to the discharge port of the centrifuge. The telescopic discharge pipe includes a first discharge pipe, an adjusting pipe, and a second discharge pipe. The first discharge pipe is connected to the feed pipe and can rotate relative to the discharge port of the centrifuge. The adjusting pipe is sleeved on the first discharge pipe and can rotate around its own axis. One end of the second discharge pipe is threaded to the adjusting pipe, and the other end of the second discharge pipe is connected to the connecting pipe. The first discharge pipe is equipped with a pushing component for pushing the material toward the second discharge pipe.

[0007] By adopting the above technical solution, the distance between the ends of the first and second feeding pipes can be adjusted by rotating the adjusting pipe, thereby changing the total length of the entire telescopic feeding pipe. At the same time, the first feeding pipe can rotate relative to the centrifuge outlet, so that even if there is a certain deviation between the centrifuge outlet and the connection position of the equipment below, the second feeding pipe can be quickly aligned and connected with the lower connecting pipe by rotating and adjusting the position of the first feeding pipe and adjusting the total length of the telescopic feeding pipe. There is no need to repeatedly adjust the position of the centrifuge or the rear docking equipment, which effectively shortens the installation and debugging time and improves the installation efficiency of the centrifuge. The pushing component reduces the probability of material blockage in the first and second feeding pipes.

[0008] Optionally, the feeding assembly includes a motor, a feeding rod, and a support frame. The motor is installed at the end of the first feeding pipe near the feed pipe. The feeding rod is located inside the first feeding pipe and is connected to the feeding rod. The support frame is located inside the second feeding pipe and can slide relative to the second feeding pipe along the axis of the feeding rod. The end of the feeding rod away from the motor is rotatably installed in the support frame and can rotate around its own axis.

[0009] By adopting the above technical solution, when the motor is started, the push rod rotates between the first and second feeding pipes, thereby pushing the material entering the centrifuge from the feed pipe from the first feeding pipe to the second feeding pipe. This allows the material to enter the connecting pipe in the second feeding pipe and fall towards the rear equipment through the connecting pipe, reducing the probability of material piling up inside the first and second feeding pipes.

[0010] Optionally, the support frame includes a support ring, a connecting arm, and a first slider. The support ring is sleeved on the end of the push rod, which can rotate relative to the support around its own axis. There are at least two connecting arms, which are mirror-distributed with the axis of the support ring as the axis of symmetry. The number of first sliders corresponds one-to-one with the number of connecting arms. One end of the connecting arm is fixedly connected to the support ring, and the other end of the connecting arm is fixedly connected to the first slider. The first slider can slide along its axial direction inside the second feed tube.

[0011] By adopting the above technical solution, when the second feeding tube moves towards the first feeding tube or away from the first feeding tube under the drive of the adjusting tube, the first slider will slide relative to the second feeding tube along the inner wall of the second feeding tube, so that the support ring can always support the end of the push rod, thereby ensuring that the push rod can run stably and reducing the flexural deformation caused by the lack of support at the end of the push rod.

[0012] Optionally, a groove is provided at the position of the first slider near the side wall of the second feed tube, and a guide bar adapted to the groove is provided on the side wall of the second feed tube, and the guide bar can slide in the groove.

[0013] By adopting the above technical solution, compared with the method of opening a chute on the side wall of the second feed pipe and having the first sliding block slide in the chute, it is less likely that material will accumulate in the chute, making it difficult for the first sliding block to slide.

[0014] Optionally, the feed pipe includes a connecting part and a rotating part that are interconnected. The connecting part is fixedly connected to the discharge port of the centrifuge, and the rotating part is located at the end of the connecting part away from the centrifuge. The rotating part can rotate around its own axis on the connecting part, and the rotating part is also hinged to the first feed pipe.

[0015] By adopting the above technical solution, the rotating part can rotate around the connecting part. In conjunction with the hinge structure between the first feeding tube and the rotating part, the first feeding tube can adjust its position and angle within a larger range, further reducing the requirements of the docking position on the installation accuracy of the centrifuge and the back-end equipment, and making it convenient for installers to quickly complete the docking and installation work.

[0016] Optionally, a first mounting plate is provided on the rotating part, one end of the first mounting plate is fixedly connected to the rotating part, and the other end of the first mounting plate is hinged to the outer wall of the first feeding pipe. A first flexible hose is provided between the rotating part and the first feeding pipe.

[0017] By adopting the above technical solution, the first mounting plate provides a stable mounting base for the hinge between the first feeding pipe and the rotating part, while the first flexible hose can play a flexible sealing role in the communication gap between the rotating part and the first feeding pipe. This not only does not restrict the rotation adjustment of the first feeding pipe relative to the rotating part, but also prevents the material from leaking out from the connection gap between the two during the unloading process, thus ensuring both the overall sealing performance and the flexibility of adjustment of the structure.

[0018] Optionally, a second mounting plate is fixedly installed on the connecting pipe. One end of the second mounting plate is fixedly connected to the connecting pipe, and the other end of the second mounting plate is hinged to the outer wall of the second discharge pipe. A second flexible hose is provided between the connecting pipe and the second discharge pipe.

[0019] By adopting the above technical solution, the second mounting plate provides a stable hinged support between the second discharge pipe and the connecting pipe, while the second flexible hose can provide a flexible seal for the connection gap between the second discharge pipe and the connecting pipe. This not only accommodates the positional shift that occurs when the angle and length of the second discharge pipe are adjusted, but also prevents material leakage from the connection during unloading, thus balancing the structural adjustability and sealing performance. At the same time, this also allows the connecting pipe to remain perpendicular to the ground when the first discharge pipe swings relative to the rotating part, enabling it to dock with the rear-end equipment below the floor. The hinge between the first discharge pipe and the rotating part, as well as the hinge between the second discharge pipe and the connecting pipe, allows the first and second discharge pipes to be tilted when conditions permit, so that the material can smoothly slide into the connecting pipe under its own weight and the pushing action of the push rod.

[0020] Optionally, guide surfaces are provided on the end face of the guide bar near the regulating tube and on the end face of the second feeding tube near the first feeding tube.

[0021] By adopting the above technical solution, when the material enters the second feeding pipe through the first feeding pipe, if the ends of the second feeding pipe and the guide strip are both flat, the material may accumulate in the regulating pipe and at the end of the guide strip. Therefore, a guide surface is set so that when the first feeding pipe and the second feeding pipe are in an inclined state, the material can move directly towards the connecting pipe along the guide surface.

[0022] Optionally, a support assembly is provided on the first feeding tube. The support assembly includes a first support rod, a second support rod, a second slider, and a sliding seat. One end of the first support rod is hinged to the outer wall of the first feeding tube, and the other end of the first support rod is hinged to the second support rod. The end of the second support rod away from the first support rod is hinged to the second slider. The sliding seat is provided on the outer wall of the second feeding tube, and the second slider is slidably provided on the sliding seat.

[0023] By adopting the above technical solution, the first support rod and the second support rod can adaptively change their included angle as the relative positions of the first and second feeding tubes change. At the same time, the second slider will slide along the sliding seat, always providing stable support for the first and second feeding tubes, thereby improving the structural stability of the first and second feeding tubes in the inclined state.

[0024] Optionally, the second slider is provided with a limit groove that is adapted to the sliding seat, and the second slider is also provided with a stop that can abut against the sliding seat.

[0025] By adopting the above technical solution, after the relative positions of the first and second feeding pipes are adjusted, the second slider can be locked in the current position by the stopper pressing against the sliding seat, thereby keeping the first and second support rods at the current support angle, preventing the second slider from accidentally sliding and changing the position of the telescopic feeding pipe during equipment operation, improving the overall stability of the structure after adjustment, and ensuring the normal operation of unloading.

[0026] In summary, this application includes at least the following beneficial technical effects: 1. By rotating the adjusting tube, the distance between the ends of the first and second feeding tubes can be adjusted, thereby changing the total length of the telescopic feeding tube. At the same time, the first feeding tube can rotate relative to the centrifuge outlet, so that even if there is a certain deviation between the centrifuge outlet and the connection position of the equipment below, the second feeding tube can be quickly aligned and connected with the lower connecting tube by rotating and adjusting the position of the first feeding tube and adjusting the total length of the telescopic feeding tube. There is no need to repeatedly adjust the position of the centrifuge or the rear docking equipment, which effectively shortens the installation and debugging time and improves the installation efficiency of the centrifuge.

[0027] 2. By setting a first support rod and a second support rod, the first support rod and the second support rod can adaptively change their included angle as the relative positions of the first feed tube and the second feed tube change. At the same time, the second slider will slide along the sliding seat to provide stable support for the first feed tube and the second feed tube, thereby improving the structural stability of the first feed tube and the second feed tube in the inclined state.

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example This application discloses a centrifuge unloading structure, referring to... Figures 1-3 The system includes a feed pipe 1, a telescopic discharge pipe 2, and a connecting pipe 3. The feed pipe 1 is used to connect to the discharge port of the centrifuge. The end of the feed pipe 1 away from the discharge port of the centrifuge is connected to the telescopic discharge pipe 2. The telescopic discharge pipe 2 is sequentially provided with a first discharge pipe 4, an adjusting pipe 5, and a second discharge pipe 6. One end of the first discharge pipe 4 is connected to the feed pipe 1 and can rotate relative to the feed pipe 1. Specifically, the feed pipe 1 includes a connecting part 17 and a rotating part 18 that are connected to each other. The connecting part 17 is fixedly connected to the discharge port of the centrifuge by a flange and bolts. The rotating part 18 is set on the connecting part 17 and can rotate about the axis of the connecting part 17. The rotating part 18 is connected to the first discharge pipe 6. The first feeding pipe 4 is connected to the second feeding pipe 6 via a threaded connection. The regulating pipe 5 is sleeved on the end of the first feeding pipe 4 away from the rotating part 18 and can rotate around the axis of the first feeding pipe 4. The end of the regulating pipe 5 away from the first feeding pipe 4 is also connected to the second feeding pipe 6 via a threaded connection. That is, the inner wall of the regulating pipe 5 is provided with an internal thread, and the outer wall of the second feeding pipe 6 is provided with a matching external thread. This makes the distance between the second feeding pipe 6 and the first feeding pipe 4 change when the regulating pipe 5 rotates around the axis of the first feeding pipe 4. The connecting pipe 3 is located on the end of the second feeding pipe 6 away from the regulating pipe 5. This allows the position of the connecting pipe 3 to change according to the distance between the first feeding pipe 4 and the second feeding pipe 6.

[0032] Specifically, an annular groove is provided on the outer wall of the first feeding pipe 4, and a ring is provided in the annular groove that can be fixedly connected to the inner wall of the adjusting pipe 5 by bolts (not shown in the figure). When the adjusting pipe 5 rotates around its own axis, the ring also rotates in the annular groove, thereby preventing the adjusting pipe 5 from falling off the first feeding pipe 4.

[0033] Reference Figure 1 , Figures 3-6 At the end of the first feeding pipe 4 furthest from the regulating pipe 5, a pushing assembly 7 is also provided. The pushing assembly 7 includes a motor 8, a pushing rod 9, and a support frame 10. The pushing rod 9 is a rod body with spiral blades on its outer wall. The motor 8 is installed at the end of the first feeding pipe 4, and its output shaft passes through the end face of the first feeding pipe 4 and is coaxially fixed with the pushing rod 9 located inside the first feeding pipe 4. This allows the pushing rod 9 to rotate around its own axis inside the first feeding pipe 4 and the second feeding pipe 6 after the motor 8 is started, thereby pushing the material accumulated in the first feeding pipe 4 by the centrifuge. The discharged material is pushed towards the second discharge pipe 6, and the support frame 10 is set inside the second discharge pipe 6. The support frame 10 is used to support the end of the push rod 9 away from the motor 8, so as to prevent it from being suspended for a long time and undergoing flexible deformation. The support frame 10 can slide relative to the second discharge pipe 6 along its axial direction. This allows the support frame 10 to maintain its position relative to the second discharge pipe 6 and not easily change when the position of the second discharge pipe 6 relative to the first discharge pipe 4 changes under the adjustment of the adjustment pipe 5, thereby increasing the support stability of the end of the push rod 9.

[0034] Specifically, the support frame 10 includes a support ring 11, a connecting arm 12, and a first slider 13. A tapered roller bearing is installed inside the support ring 11, and the end of the push rod 9 is connected to the inner ring of the bearing on the support ring 11. This allows the push rod 9 to rotate relative to the support ring 11 around its own axis, thus achieving material pushing. Two connecting arms 12 are provided, symmetrically distributed about the axis of the support ring 11. The number of first sliders 13 corresponds one-to-one with the number of connecting arms 12. One end of each connecting arm 12 is fixedly connected to the outer wall of the support ring 11, while the other end is perpendicularly fixed to the first slider 13. A groove 14 is provided on the first slider 13 near the inner wall of the second discharge pipe 6. A guide strip 15, adapted to the groove 14, is provided on the inner wall of the second discharge pipe 6. The length direction of the guide strip 15 is parallel to the axis of the second discharge pipe 6. This ensures that the support ring 11 supports the push rod 9 without interfering with the displacement of the second discharge pipe 6.

[0035] To further increase the adjustability range of the first feed tube 4 and the second feed tube 6, a first mounting plate 19 is provided on the rotating part 18. In this embodiment, there are two first mounting plates 19, which are respectively provided on both sides of the rotating part 18. One end of the first mounting plate 19 is fixedly connected to the outer wall of the rotating part 18, and the other end of the first mounting plate 19 has a hole. A rod that can pass through the hole is provided on the outer wall of the first feed tube 4, thereby realizing the hinge. It should be noted that the two mounting plates should be The rotating part 18 is hinged to the outer wall of the first feeding pipe 4, thereby making room for the push rod 9 inside the first feeding pipe 4. A first flexible hose 20 is also provided between the rotating part 18 and the first feeding pipe 4. One end of the first flexible hose 20 is fixedly connected to the rotating part, and the other end of the first flexible hose is inserted into the first feeding pipe 4. This allows the first flexible hose 20 to bend along with the rotating part 18 when the first feeding pipe 4 swings up and down relative to the rotating part 18. At the same time, the first flexible hose 20 also reduces the probability of material leaking out from the gap between the rotating part 18 and the first feeding pipe 4.

[0036] Correspondingly, two second mounting plates 21 are provided on the connecting pipe 3. One end of the second mounting plate 21 is fixedly installed on the outer wall of the connecting pipe 3, while the other end is hinged in the same way as the first mounting plate 19 and the first discharge pipe 4. This allows the connecting pipe 3 to remain perpendicular to the ground on the second discharge pipe 6 after the first discharge pipe 4 swings, thus connecting and communicating with the rear-end equipment below the floor. A second flexible hose 22 is provided between the second discharge pipe 6 and the connecting pipe 3. The second flexible hose 22 is inserted into the second discharge pipe 6, and the end away from the second discharge pipe 6 is fixedly connected to the connecting pipe 3. This prevents the material discharged from the second discharge pipe 6 from easily leaking out through the gap between the second discharge pipe 6 and the connecting pipe 3.

[0037] Due to the hinge between the first discharge pipe 4 and the first mounting plate 19 on the rotating part 18, and the hinge between the second discharge pipe 6 and the second mounting plate 21 on the connecting pipe 3, the first discharge pipe 4 and the second discharge pipe 6 can be in an inclined state. This not only increases the range of selectable positions of the connecting pipe 3, but also allows the material in the first discharge pipe 4 and the second discharge pipe 6 to be in an inclined state, and then slide down under its own gravity, reducing the probability of material blockage.

[0038] Specifically, the holes on the first mounting plate 19 and the holes on the second mounting plate 21 are all waist-shaped holes with their extension direction perpendicular to the ground. This allows the height of the first discharge pipe 4 and the second discharge pipe 6 in the vertical direction to be adjusted while ensuring normal unloading.

[0039] Furthermore, guide surfaces 16 are provided on the end face of the guide strip 15 near the regulating pipe 5 and the end face of the second feeding pipe 6 near the first feeding pipe 4. The guide surfaces 16 on the guide strip 15 and the second feeding pipe 6 can reduce the probability of material accumulating on their end faces. Specifically, the guide surface 16 on the guide strip 15 makes the distance between the two side walls of the guide surface 16 gradually decrease from the direction near the regulating pipe 5 to the direction away from the regulating pipe 5, thereby forming a tip and reducing the probability of material accumulating on the end face of the guide strip 15. The guide surface 16 on the second feeding pipe 6 is provided on the inner wall of the second feeding pipe 6 near the first feeding pipe 4, and its inner diameter gradually decreases from the direction near the first feeding pipe 4 to the direction away from the first feeding pipe 4. This makes it easy for material to accumulate on the end face of the second feeding pipe 6 when passing through the regulating pipe 5, thereby increasing the probability of material passing through.

[0040] Furthermore, a support assembly 23 is provided on the outer wall of the first feeding tube 4. The support assembly 23 includes a first support rod 24, a second support rod 25, a second slider 26, and a sliding seat 27. One end of the first support rod 24 is hinged to the outer wall of the first feeding tube 4, and the other end is hinged to one end of the second support rod 25. The end of the second support rod 25 away from the first support rod 24 is hinged to the second slider 26. The sliding seat 27 is fixedly disposed on the outer wall of the second feeding tube 6 along the length direction of the second feeding tube 6. The second slider 26 is engaged with the sliding seat 27 through a limiting groove 28 provided thereon, and can move along the length of the sliding seat 27. The sliding direction is 26 degrees. Specifically, the cross-section of the sliding seat 27 is "I" shaped, and the limiting groove 28 is a C-shaped groove. This prevents the second slider 26 from easily detaching from the sliding seat 27. When the first discharge pipe 4 and the second discharge pipe 6 swing to adjust their angles, the included angle between the first support rod 24 and the second support rod 25 is adaptively adjusted according to the change in structural position. The second slider 26 slides synchronously along the sliding seat 27. The hinge point of the first support rod 24 and the second support rod 25 is always in contact with the ground, thus providing stable support for the first discharge pipe 4 and the second discharge pipe 6 to share the impact from unloading on the first discharge pipe 4.

[0041] A stop 29 is also provided on the second slider 26. In this embodiment, the stop 29 is a bolt, which is connected to the second slider 26 by means of threaded engagement. This allows the second slider 26 to be fixed in position on the sliding seat 27 by tightening the stop 29.

[0042] In other embodiments, the stop 29 can also be a set screw, which is turned so that the end of the set screw abuts against the sliding seat 27, thereby fixing the position of the second slider 26 on the sliding seat 27.

[0043] The implementation principle of this application embodiment is as follows: Before installation, the connecting part 17 is fixed to the centrifuge outlet, and the connecting pipe 3 is pre-fixed to the feed inlet of the rear equipment. If there is a positional deviation between the centrifuge outlet and the rear feed inlet, there is no need to move the centrifuge or the rear equipment. Only the adjusting pipe 5 needs to be rotated to drive the second feeding pipe 6 to move along the axial direction through the threaded transmission, and adjust the total length of the telescopic feeding pipe 2. Then, the rotating part 18 is rotated to adjust the circumferential position of the first feeding pipe 4, and the first feeding pipe 4 is swung to adjust the tilt angle, which can drive the connecting pipe 3 to move and align with the feed inlet of the rear equipment. After alignment, the stop 29 on the second slider 26 is tightened to lock the support structure. Finally, the installation is completed by fixing the connecting pipe 3 to the rear feed inlet.

[0044] 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.
