Description

Technical Field

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

[0002] A centrifuge is a device that uses centrifugal force to separate liquids from solid particles or different components in a mixture of liquids. Centrifuges are widely used in chemical, petroleum, food and other industrial fields.

[0003] Currently, the discharge port of centrifuges is often located at the bottom of the centrifuge. In most factories, centrifuges are placed on high floors, and holes are made in the floor slabs so that the equipment on the lower floors used to process the solid materials inside the centrifuge can be connected to the discharge port of the centrifuge. The height difference allows the solid materials inside the centrifuge to be processed as soon as they are discharged from the centrifuge.

[0004] However, because the centrifuge's discharge port needs to be aligned with the inlet of the equipment below, after initially fixing the positions of the centrifuge and the material processing equipment, workers still need to use pry bars or other means to make minor adjustments to the positions of the centrifuge or material processing equipment so that the centrifuge's discharge port can be aligned with the inlet of the equipment below before subsequent connections can be made. During the adjustment process, the positions of the bolt holes on the centrifuge's discharge port and the equipment below's inlet need to be aligned so that the connection between the centrifuge's discharge port and the equipment below can be achieved by bolts. Therefore, the positional accuracy required for the adjustment is high, and this process often takes a lot of time. Summary of the Invention

[0005] To facilitate the alignment of bolt holes between the centrifuge and other equipment, thereby enabling the connection between the centrifuge and other equipment, this application provides a centrifuge unloading structure.

[0006] The centrifuge unloading structure provided in this application adopts the following technical solution: The system includes a connecting pipe and a discharge assembly. The discharge assembly is located below the centrifuge outlet. The centrifuge outlet has a first flange. The discharge assembly includes a discharge pipe with an inlet at one end and a second flange at the inlet. The inlet has a first boss on its inner wall and a second boss on its inner wall. One end of the connecting pipe abuts against the first boss, and the other end of the connecting pipe abuts against the second boss. The first flange and the second flange are connected by bolts. The second flange has a waist-shaped hole for the bolts to pass through, which extends around the axis of the connecting pipe. The end of the discharge pipe away from the centrifuge outlet has a discharge outlet.

[0007] By adopting the above technical solution, when the feed inlet on the unloading pipe is connected to the centrifuge outlet, the connecting pipe is located between the first boss and the second boss. When it is necessary to adjust the angle of the unloading pipe, the bolts between the feed inlet and the centrifuge outlet can be loosened, allowing the unloading pipe to rotate around the axis of the connecting pipe within the extension range of the oblong hole. This allows the unloading pipe to connect with the relevant device located after the centrifuge process, which is slightly off-center. The bolts do not need to be removed during the entire angle adjustment process. When it is necessary to adjust the height, the bolts can be further loosened, allowing the first flange to... Separated from the second flange, the height of the discharge pipe can be adjusted. The connecting pipe ensures that the material inside the centrifuge will not leak out from the gap between the centrifuge outlet and the feed inlet on the discharge pipe during the centrifuge discharge process. Subsequently, a shim can be placed between the centrifuge outlet and the feed inlet on the discharge pipe before tightening the bolts to fix the centrifuge outlet and the feed inlet on the discharge pipe. The angle and height of the discharge pipe can be adjusted according to the actual situation, reducing the equipment position accuracy, saving workers' time in adjusting the equipment, and achieving the effect of aligning the bolt holes of the centrifuge with other equipment.

[0008] Optionally, the inlet and outlet are perpendicular to the length of the discharge pipe. The discharge assembly also includes an end cap, a motor, and a discharge shaft. The end cap is connected to the end of the discharge pipe away from the inlet by a threaded connection. The motor is mounted on the end cap. The discharge shaft is located inside the discharge pipe. One end of the discharge shaft is connected to the motor, and the other end of the discharge shaft is inserted into the end of the discharge pipe away from the end cap. The discharge shaft can rotate around its own axis. The discharge shaft is equipped with spiral blades, which are distributed along the length of the discharge shaft.

[0009] By adopting the above technical solution, after the material in the centrifuge is centrifuged, the solid material in the centrifuge enters the unloading pipe through the centrifuge outlet. The output shaft of the motor is connected to the end of the unloading shaft. The motor drives the unloading shaft to rotate around its own axis, which in turn drives the spiral blades on the unloading shaft to rotate. This allows the solid material that enters the unloading pipe through the feed inlet to fall out through the unloading outlet under the action of the spiral blades. The unloading shaft plays a role in reducing the risk of solid material clogging the unloading pipe.

[0010] Optionally, an installation strip is provided at the end of the spiral blade away from the rotating rod. The installation strip is fixedly connected to the spiral blade. A scraping assembly is provided on the side of the installation strip away from the rotating rod. The scraping assembly is used to clean the inner wall of the unloading pipe.

[0011] By adopting the above technical solution, when the spiral blades rotate with the unloading shaft, the cleaning components located on the spiral blades are used to clean the solid material adhering to the inner wall of the unloading pipe, reducing the occurrence of material adhering to the inner wall of the unloading pipe not being cleaned in time and thus mixing with other materials, which would affect the subsequent materials.

[0012] Optionally, a sliding groove is provided near the inner wall of the unloading pipe on the installation strip. The scraping assembly includes a sliding strip, a cleaning component, and a spring. The cleaning component is fixedly connected to the sliding strip. The sliding strip is located in the sliding groove and slides in cooperation with the sliding groove. The sliding direction of the sliding strip is perpendicular to the length direction of the installation strip. The spring is located in the sliding groove. One end of the spring is connected to the bottom of the sliding groove, and the other end of the spring is connected to the sliding strip. The sliding direction of the sliding strip is perpendicular to the length direction of the installation strip.

[0013] By adopting the above technical solution, the cleaning component can be a flexible scraper made of silicone or a brush bristle. The sliding strip is located in the sliding groove, and the sliding direction of the sliding strip is perpendicular to the length direction of the mounting strip. The spring is used to give the mounting strip a force to move towards the side wall of the unloading pipe. The spring enables the cleaning component on the mounting strip to always be in contact with the inner wall of the unloading pipe, thereby enabling the cleaning component to always be in contact with the inner wall of the unloading pipe.

[0014] Optionally, each end of the mounting strip is provided with an adjustment component. The adjustment component includes a mounting block and an adjustment element. The mounting block is fixedly connected to the mounting strip, and the adjustment element is connected to the mounting block by a threaded connection. After passing through the mounting block, the adjustment element abuts against the sliding strip.

[0015] By adopting the above technical solution, the mounting block is used to limit the sliding bar, reducing the risk of the sliding bar coming out of the sliding groove. The adjusting component is an ordinary bolt. By rotating the adjusting component, the extension length of the adjusting component is adjusted, thereby achieving the effect of adjusting the compression of the spring. Adjustment is made when the cleaning component is too tight or too loose against the inner wall of the unloading pipe, so as to ensure the cleaning effect of the cleaning component on the inner wall of the unloading pipe.

[0016] Optionally, the outer walls at both ends of the connecting pipe are provided with tapered surfaces, and the distance between the tapered surfaces and the inner wall of the connecting pipe gradually decreases from the middle section of the connecting pipe toward the end of the connecting pipe.

[0017] By adopting the above technical solution, tapered surfaces are provided at both ends of the connecting pipe, and the distance between the tapered surfaces and the inner wall of the connecting pipe gradually decreases from the middle of the connecting pipe toward the end of the connecting pipe, making it easier for the connecting pipe to be inserted into the feed inlet of the unloading pipe and the discharge outlet of the centrifuge, thus facilitating installation.

[0018] Optionally, the connecting pipe has a groove woven along its circumferential wall at one end of the centrifuge outlet, and a sealing ring is installed in the groove, which abuts against the inner wall of the centrifuge outlet.

[0019] By adopting the above technical solution, the sealing ring increases the sealing between the connecting pipe and the inner wall of the centrifuge outlet, reducing the possibility of leakage from the gap between the connecting pipe and the inner wall of the centrifuge outlet during discharge.

[0020] Optionally, a support assembly is provided on the side of the unloading pipe near the end cap. The support assembly includes a first support rod and a second support rod. One end of the first support rod is hinged to the outer wall of the unloading pipe, and the other end of the first support rod is hinged to the second support rod. A slider is hinged to the end of the second support rod away from the first support rod. A groove adapted to the slider is provided on the outer wall of the unloading pipe. The groove extends in the same direction as the length of the unloading pipe. The slider slides in cooperation with the groove. An auxiliary wheel is provided on the first support rod near the second support rod.

[0021] By adopting the above technical solution, when the centrifuge device is in the state of waiting to be transported, the auxiliary wheel at the hinge between the first support rod and the second support rod plays the role of supporting the unloading pipe, reducing the possibility of deformation of the unloading pipe under the action of gravity; at the same time, during the transportation of the centrifuge device, the height of the auxiliary wheel can be adjusted by adjusting the position of the slider on the second support rod, so that even if the centrifuge device is a certain distance from the ground, the auxiliary wheel can still be in contact with the ground, and thus continue to support the unloading pipe.

[0022] Optionally, the chute is a dovetail groove, and the distance between the bottom surface of the chute and the outer wall of the unloading pipe gradually decreases from the direction closer to the first support rod to the direction farther away from the first support rod. A limiting member is provided on the slider, and the limiting member is threadedly engaged with the slider. After passing through the slider, the limiting member abuts against the bottom surface of the chute.

[0023] By adopting the above technical solution, the limiting component is also a common bolt, and the slide is a dovetail groove so that the slider will not easily come out in the direction perpendicular to the bottom surface of the slide. The distance between the bottom surface of the slide and the outer wall of the unloading pipe gradually decreases from the direction close to the first support rod to the direction away from the first support rod, so that the limiting component can better abut against the bottom surface of the slide, and the position of the slider in the slide will not easily change.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing connecting pipes at the feed inlet and centrifuge outlet on the discharge pipe, there will be no gap between the feed inlet and the main feed inlet of the centrifuge when the bolts connecting the feed inlet and the centrifuge outlet are loosened, reducing the risk of material leakage when rotating the discharge pipe. Since the bolt hole on the feed inlet is a slotted hole, the angle of the discharge pipe can be adjusted after the bolts are loosened, and the position of the discharge outlet on the discharge pipe can also be changed with the change of the discharge pipe angle, thereby facilitating the connection of the centrifuge with other equipment. 2. By setting tapered surfaces at both ends of the connecting pipe, the connecting pipe can be more easily inserted into the feed inlet and the centrifuge outlet. The connecting pipe also plays an auxiliary positioning role, thereby reducing the time required to install the discharge pipe on the centrifuge. 3. By installing a scraping component on the spiral blades, the scraping component can simultaneously clean the material adhering to the inner wall of the discharge pipe when the motor drives the discharge shaft to rotate, thereby reducing the risk of loss caused by subsequent material mixing.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a centrifuge unloading structure, referring to... Figure 1 , Figure 2 as well as Figure 3The centrifuge includes a centrifuge outlet 1 perpendicular to the ground. A first flange 33 is provided at the end of the centrifuge outlet 1 away from the centrifuge. Below the centrifuge outlet 1, a discharge assembly 2 is provided. The discharge assembly 2 includes a discharge pipe 3. A feed inlet 4 with its axis perpendicular to the axis of the discharge pipe 3 is provided at one end of the discharge pipe 3. The length direction of the feed inlet 4 is perpendicular to the length direction of the discharge pipe 3. A second flange 34 is provided at the end of the feed inlet 4 away from the discharge pipe 3. A first boss 5 is provided on the inner wall of the centrifuge outlet 1, and a second boss 6 is provided on the inner wall of the feed inlet 4. A connecting pipe 31 is provided between the centrifuge outlet 1 and the feed inlet 4. The two ends of the connecting pipe 31 are respectively provided with conical surfaces 22 for easy insertion into the centrifuge outlet 1 and the feed inlet 4.

[0029] When the first boss 5 abuts against one end of the connecting pipe 31 and the second boss 6 abuts against the other end of the connecting pipe 31, the first flange 33 and the second flange 34 abut against each other. In order to enable the unloading pipe 3 to rotate around the axis of the connecting pipe 31, the second flange 34 is also provided with a waist-shaped hole 7 extending around the axis of the connecting pipe 31, and a connecting bolt 35 is inserted into the waist-shaped hole 7. After passing through the waist-shaped hole 7, the connecting bolt 35 is connected to the first flange 33 by means of threaded engagement.

[0030] Reference Figure 3 To prevent material from leaking out from the gap between the outer wall of the connecting pipe 31 and the inner wall of the centrifuge outlet 1 during discharge, a groove 23 is provided along the circumferential wall at one end of the connecting pipe 31 located at the centrifuge outlet 1. A sealing ring 24 is provided in the groove 23, and the sealing ring 24 abuts against the inner wall of the centrifuge outlet 1, thereby increasing the sealing between the outer wall of the connecting pipe 31 and the inner wall of the centrifuge outlet 1.

[0031] Reference Figure 2 The unloading assembly 2, in addition to the unloading pipe 3, also includes an end cap 9, a motor 10, and an unloading shaft 11. The end cap 9 is threadedly connected to the end of the unloading pipe 3 furthest from the inlet 4. The motor 10 is mounted on the end cap 9. The unloading shaft 11 is located inside the unloading pipe 3, and one end of the unloading shaft 11 is connected to the output shaft of the motor 10 via a coupling. The other end of the unloading shaft 11 is inserted into the inner wall of the unloading pipe 3 furthest from the end cap 9. When the motor 10 is connected to an external power source, the output shaft of the motor 10 drives the unloading shaft 11 to rotate synchronously. On the upper part, a spiral blade 12 is arranged along the length direction. When the spiral blade 12 rotates, the material entering the discharge pipe 3 through the feed port 4 gradually moves from the feed port 4 towards the end cover 9, reducing the risk of material clogging the discharge pipe 3. On the discharge pipe 3, near the end cover 9, there is also a discharge outlet 8 with the axis perpendicular to the axis of the discharge pipe 3. This allows the material in the discharge pipe 3 to be discharged from the discharge outlet 8 when it moves towards the end cover 9 and enter the relevant equipment of the next process after the centrifuge.

[0032] Reference Figure 2 , Figure 4 as well as Figure 5 A mounting strip 13 is fixedly connected to the spiral blade 12 at a position away from the rotating rod. The mounting strip 13 is parallel to the unloading shaft 11. The side of the mounting strip 13 near the inner wall of the unloading shaft 11 has a sliding groove 14 that is aligned with the length direction of the mounting strip 13. A scraping assembly 15 is provided in the sliding groove 14. The scraping assembly 15 includes a sliding strip 16, a spring 18, and a cleaning component 17. The sliding strip 16 is slidably engaged with the sliding groove 14, and the length of the sliding strip 16 is adapted to the length of the sliding groove 14. The cleaning component 17 is mounted on the sliding strip 16 and can be installed along the sliding groove 16. The bristles of the sliding strip 16 are distributed along its length or are flexible silicone strips that are aligned with the length of the sliding strip 16. The spring 18 is located inside the sliding groove 14. One end of the spring 18 is connected to the bottom surface of the sliding groove 14, and the other end of the spring 18 is connected to the bottom of the sliding groove 29. The spring 18 applies a force to the sliding strip 16 to move closer to the inner wall of the discharge pipe 3, so that the cleaning component 17 can always be in contact with the inner wall of the discharge pipe 3. Thus, when the motor 10 drives the discharge shaft 11 to rotate, the cleaning component 17 can simultaneously clean the material adhering to the inner wall of the discharge pipe 3.

[0033] Reference Figure 4 and Figure 5 The two ends of the mounting strip 13 are respectively equipped with adjustment components 19. The adjustment components 19 include mounting blocks 20 and adjustment members 21. The mounting blocks 20 are installed at the ends of the mounting strip 13 by bolts. The adjustment members 21 are bolts and are perpendicular to the mounting strip 13. After passing through the mounting blocks 20, the adjustment members 21 abut against the sliding strip 16. This allows the operator to adjust the compression of the spring 18 by simultaneously adjusting the extension length of the adjustment members 21 at both ends of the mounting strip 13 on the mounting blocks 20. This, in turn, adjusts the abutment force between the cleaning member 17 and the inner wall of the unloading pipe 3. This ensures that when the cleaning member 17 abuts against the inner wall of the unloading pipe 3, the unloading shaft 11 will not be difficult to rotate due to excessive spring force of the spring 18. It also ensures that when the cleaning member 17 abuts against the inner wall of the unloading pipe 3, the cleaning member 17 will not be unable to perform its cleaning function due to insufficient spring force of the spring 18.

[0034] Reference Figure 1 and Figure 2Below the discharge pipe 3, near the discharge outlet 8, a support assembly 25 is provided. The support assembly 25 includes a first support rod 26 and a second support rod 27. One end of the first support rod 26 is hinged to the outer wall of the discharge pipe 3, and the other end is hinged to the second support rod 27. An auxiliary wheel 28 is coaxially mounted on the hinge axis of the first and second support rods 26 and 27. A slider 30 is hinged to the side of the second support rod 27 away from the first support rod 26. A groove 29 is provided on the outer wall of the discharge pipe 3. The groove 29 can be a dovetail groove or a C-shaped groove. The length direction of the groove 29 is consistent with the length direction of the discharge pipe 3. Adapted to the slide groove 29, the slider 30 is provided with a limiting member 32. The limiting member 32 is connected to the slider 30 by a threaded engagement. The limiting member 32 is a common bolt. After passing through the slider 30, the limiting member 32 abuts against the bottom surface of the slide groove 29, so that the slider 30 is pressed against the slide groove 29. This realizes the positioning of the slider 30 in the slide groove 29 and the adjustment of the height of the auxiliary wheel 28. This ensures that the auxiliary wheel 28 can always support the unloading pipe 3 when it is needed, reducing the risk of deformation of the unloading pipe 3 due to gravity. When the auxiliary wheel 28 is not needed, the position of the slider 3030 in the slide groove 29 can be adjusted to retract the auxiliary wheel 28, which can reduce the space occupied.

[0035] The distance between the bottom surface of the chute 29 and the outer wall of the unloading pipe 3 gradually decreases from the direction closer to the first support rod 26 toward the direction farther away from the first support rod, so that the slider 30 will not easily move after the limiting member 32 abuts against the bottom surface of the chute 29, and thus the position of the auxiliary wheel 28 will not easily change even after it has been subjected to a greater impact.

[0036] The implementation principle of the centrifuge unloading structure in this application embodiment is as follows: when the centrifuge is equipped with the unloading structure of this application and is in a state of waiting for transportation, the position of the slider 30 in the slide groove 29 is first adjusted so that the auxiliary wheel 28 at the hinge of the first support rod 26 and the second support rod 27 abuts against the ground, so that the auxiliary wheel 28 supports the unloading pipe 3 and reduces the risk of deformation of the unloading pipe 3 due to gravity.

[0037] When the centrifuge is transported to a higher floor and needs to be connected to equipment on a lower floor, the auxiliary wheel 28 is retracted by adjusting the position of the slider 30 within the slide groove 29. Then, the connecting bolt 35 between the inlet 4 and the outlet 1 of the centrifuge on the discharge pipe 3 is loosened, allowing the discharge pipe 3 to rotate around the axis of the connecting pipe 31, thus adjusting the angle of the discharge pipe 3. Once the discharge outlet 8 on the discharge pipe 3 is aligned with the inlet 4 on the lower floor equipment, if the height of the discharge pipe 3 needs to be adjusted, the connecting bolt 35 can be further loosened until the discharge outlet 8 aligns with the lower floor equipment. After the feed inlet 4 of the floor equipment comes into contact with the material, it is connected by bolts. Due to the limiting effect of the first boss 5 and the second boss 6, the connecting pipe 31 is always located between the feed inlet 4 on the unloading pipe 3 and the centrifuge outlet 11. This ensures that even if the centrifuge outlet 1 does not come into contact with the feed inlet 4 on the unloading pipe 3, there will be no leakage during the centrifuge discharge process. Subsequently, it is only necessary to place a pad between the centrifuge outlet 11 and the feed inlet 4 and tighten the connecting bolts 35 connecting the first flange 33 and the second flange 34 to adjust the height of the unloading pipe 3.

[0038] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
