Description

Technical Field

[0001] This application relates to the field of tubular centrifuge drum cleaning technology, and more particularly to tubular centrifuge drum cleaning device. Background Technology

[0002] Tubular centrifuges are used to separate various difficult-to-separate emulsions, with the drum being the most important rotating separating component. A major drawback of tubular centrifuges is their intermittent operation; due to the small volume of the drum, frequent shutdowns for cleaning are necessary.

[0003] In order to improve cleaning efficiency, existing technologies typically involve integrating cleaning equipment into the tubular centrifuge without disassembling the drum. Examples include CN111111939A, a tubular centrifuge cleaning system and method, and CN115739414A, a tubular centrifuge with a convenient drum cleaning function. However, this method requires modification of the tubular centrifuge structure, resulting in high costs and complex overall structure, leading to inconvenient maintenance. Another approach is to directly disassemble the drum and transport it to the cleaning equipment for cleaning, which can effectively control cleaning costs. However, this method is usually entirely manual, resulting in low cleaning efficiency and easy damage to the drum due to impacts, leading to low reliability. Utility Model Content

[0004] The purpose of this application is to address the problem of low cleaning efficiency and reliability of tubular centrifuge drums in the prior art. Therefore, this application provides a tubular centrifuge drum cleaning device, which improves the cleaning efficiency and reliability of tubular centrifuge drums by integrating a cleaning tank, a lifting bracket, and a telescopic cleaning mechanism, reducing manual intervention through automatic drive, and through a special design of the brackets.

[0005] This application provides a centrifuge drum cleaning device. The drum includes a cylinder and a detachable and washable lower cover disposed at the lower end of the cylinder. A limiting ring is also sleeved on the lower end of the cylinder. The limiting ring has a limiting groove with an open end facing the lower cover. The device includes:

[0006] A cleaning tank is used to hold the rotating drum;

[0007] A lifting bracket for moving the drum in and out of the cleaning tank, the lifting bracket being connected to a lifting drive component, and having a first claw and a second claw. The first claw supports the limiting ring of the drum, and the second claw supports the drum body, with the supporting surface of the second claw higher than that of the first claw, so that the supported drum is tilted with its lower end lower than its upper end. The first claw also has a limiting block adapted to a limiting groove on the limiting ring of the drum to restrict the drum's rotation and continuous movement towards its lower end.

[0008] The telescopic cleaning mechanism, located outside the cleaning tank, includes a telescopic drive and a cleaning rod connected to the telescopic drive. The cleaning rod is connected to a cleaning liquid supply mechanism, and the cleaning rod can extend into the cleaning tank and into the cylinder of the rotating drum for cleaning under the drive of the telescopic drive.

[0009] By adopting the above technical solution, the cleaning tank, lifting bracket, and telescopic cleaning mechanism involved in drum cleaning are integrated. The lifting bracket can automatically rise and fall under the drive of the lifting drive component, and the cleaning rod in the telescopic cleaning mechanism can automatically extend and retract under the drive of the telescopic drive component, reducing manual intervention and improving the efficiency and reliability of drum cleaning in tubular centrifuges. Furthermore, through the special design of the first and second claws on the lifting bracket, on the one hand, the height difference between their supporting surfaces is used to tilt the drum downward, thereby facilitating the flow of internal dirt with the cleaning process. On the other hand, the limiting block of the first claw supporting the lower end of the drum cooperates with the limiting groove on the drum to prevent the drum from rotating during the cleaning process and from continuously sliding down along the tilt direction, thereby improving the safety of the drum cleaning process and further enhancing the reliability of drum cleaning in tubular centrifuges.

[0010] In some embodiments, the system further includes a main support frame and a secondary support frame arranged side by side, the cleaning tank is disposed on the main support frame, the lifting bracket and the telescopic cleaning mechanism are disposed on adjacent sides of the main support frame, and the first claw on the lifting bracket is close to the telescopic cleaning mechanism, the telescopic cleaning mechanism is located inside the secondary support frame;

[0011] The secondary support frame is equipped with a storage tray;

[0012] The lifting bracket can move the drum to a height position no lower than the top of the cleaning tank or the higher of the storage tray.

[0013] By adopting the above technical solution, the volume of the device is effectively controlled by rationally distributing the cleaning tank, lifting bracket, and telescopic cleaning mechanism at various positions of the main support frame and rationally arranging the secondary support frame. Furthermore, by setting a storage tray on the secondary support frame, and by allowing the lifting bracket to move the drum to a height not lower than the top of the cleaning tank or the higher of the storage tray, it is convenient to remove the lower cover of the drum and take out and place internal residues and components (such as triangular plates), thereby improving the convenience of cleaning.

[0014] In some embodiments, the first claw includes a first half-ring body adapted to the limiting ring of the drum, and the second claw includes a second half-ring body adapted to the cylinder of the drum.

[0015] The limiting block is provided at the end of the first semi-ring body.

[0016] In some embodiments, the lifting bracket includes a vertically connected support portion and a connecting portion. The support portion is provided with a first claw and a second claw. The connecting portion is connected to a lifting drive component, and a guide rod is also provided between the lifting drive component and the connecting portion. The lifting drive component drives the connecting portion to move up and down along the guide rod, and drives the support portion to enter and exit the cleaning tank.

[0017] In some embodiments, the telescopic drive member is disposed close to the cleaning tank, and the drive end of the telescopic drive member is away from the cleaning tank.

[0018] The cleaning rod is arranged parallel to the drive end of the telescopic drive component, and the two are connected by their ends located on the same side.

[0019] In some embodiments, a nozzle is provided at the end of the cleaning rod near the cleaning tank, and the nozzle is located inside the cleaning tank and can be moved by the cleaning rod.

[0020] In some embodiments, the cleaning rod is provided with bristles in the circumferential direction.

[0021] In some embodiments, the supporting surface of the second claw is higher than the supporting surface of the first claw, and the supporting drum is tilted at a 4°-7° angle.

[0036] The drum 10 of a tubular centrifuge typically includes a cylinder 11 and a removable and washable lower cover located at the lower end of the cylinder 11. A limiting ring is also fitted onto the lower end of the cylinder 11, and the limiting ring has a limiting groove 121 with an open end facing the lower cover. Some drums 10 may also have centrifugation auxiliary components, such as triangular plates, installed inside the cylinder 11.

[0037] The drum 10 requires regular cleaning. One cleaning method involves removing the drum 10 from the tubular centrifuge, transporting it, and cleaning it separately. The specific cleaning process includes first removing the bottom cover, removing bottom residue and internal components, and then cleaning the inner wall of the drum 11. Usually, the equipment used in this method is placed arbitrarily, and the cleaning process is entirely done manually, resulting in low cleaning efficiency and reliability.

[0038] Therefore, this application provides a cleaning device for a tubular centrifuge drum 10, comprising:

[0039] The cleaning tank 200 is used to accommodate the rotating drum 10.

[0040] A lifting bracket 300 is used to move the drum 10 in and out of the cleaning tank 200. The lifting bracket 300 is connected to a lifting drive component 303, and the lifting bracket 300 is provided with a first claw 310 and a second claw 320. The first claw 310 is used to support the limiting ring of the drum 10, that is, to support the lower end of the drum 10. The second claw 320 is used to support the cylinder 11 of the drum 10, affecting the upper end near the drum 10, thereby improving the load-bearing stability and reliability. Furthermore, the supporting surface of the second claw 320 is higher than the supporting surface of the first claw 310, so that the supported drum 10 is in an inclined posture with the lower end lower and the upper end higher. The first claw 310 is provided with a limiting block 311 that matches the limiting groove 121 on the limiting ring of the drum 10, so as to limit the rotation of the drum 10 and its continuous movement in the direction of its lower end.

[0041] The telescopic cleaning mechanism 400, located outside the cleaning tank 200, includes a telescopic drive 410 and a cleaning rod 420 connected to the telescopic drive 410. The cleaning rod 420 is connected to a cleaning liquid supply mechanism, and the cleaning rod 420 can extend into the cleaning tank 200 and into the cylinder 11 of the drum 10 for cleaning under the drive of the telescopic drive 410.

[0042] This method integrates the cleaning tank 200, lifting bracket 300, and telescopic cleaning mechanism 400 involved in the cleaning of the drum 10. The lifting bracket 300 can automatically rise and fall under the drive of the lifting drive 303, and the cleaning rod 420 in the telescopic cleaning mechanism 400 can automatically extend and retract under the drive of the telescopic drive 410, reducing manual intervention and improving the cleaning efficiency and reliability of the tubular centrifuge drum 10.

[0043] Furthermore, through the special design of the first claw 310 and the second claw 320 on the lifting bracket 300, on the one hand, the height difference between the two supporting surfaces is used to make the drum 10 tilt downward, thereby facilitating the internal dirt to flow out from its lower end with the cleaning liquid; on the other hand, by the limiting block 311 of the first claw 310 supporting the lower end of the drum 10 cooperating with the limiting groove 121 on the drum 10, the drum 10 is prevented from rotating on its own during the cleaning process and from continuously sliding down along the tilt direction, thereby improving the safety of the drum 10 during the cleaning process and further improving the reliability of cleaning the drum 10 of the tubular centrifuge.

[0044] In one embodiment, the device further includes a main support frame 500 and a secondary support frame 600 arranged side by side. The cleaning tank 200 is disposed on the main support frame 500. The lifting bracket 300 and the telescopic cleaning mechanism 400 are respectively disposed on two adjacent sides of the main support frame 500. The first claw 310 on the lifting bracket 300 is close to the telescopic cleaning mechanism 400. The telescopic cleaning mechanism 400 is located inside the secondary support frame 600. That is, by reasonably distributing the cleaning tank 200, the lifting bracket 300 and the telescopic cleaning mechanism 400 in various positions of the main support frame 500, and reasonably arranging the secondary support frame 600, the size of the device is effectively controlled and the operation is convenient.

[0045] The auxiliary support frame 600 is equipped with a storage tray 610. The lifting bracket 300 can move the drum 10 to a height position not lower than the top of the cleaning tank 200 or the higher of the storage tray 610, so as to facilitate the removal of the lower cover of the drum 10, take out and place internal residues and components (such as triangular plates), etc., and improve the convenience of cleaning.

[0046] In one embodiment, the first claw 310 includes a first half-ring body 312 adapted to the limiting ring of the drum 10, and the second claw 320 includes a second half-ring body 321 adapted to the cylinder 11 of the drum 10.

[0047] Limiting blocks 311 are provided at the ends of the first semi-ring body 312.

[0048] In one specific embodiment, the end of the first semi-ring body 312 is bent inward and extended to form a limiting block 311.

[0049] When placing the drum 10, the drum 10 can be transferred to the top of the first claw 310 and the second claw 320 by the transfer device, and tilted and lowered by the transfer device until it is supported by the first claw 310 and the second claw 320 (at this time, the limiting block 311 is disengaged from the limiting groove 121). Then, it is moved backward by the transfer device until the limiting block 311 slides into the limiting groove 121 and abuts against its end, thereby fixing the posture of the drum 10.

[0050] In one embodiment, the lifting bracket 300 includes a vertically connected support portion 301 and a connecting portion 302. The support portion 301 is provided with a first claw 310 and a second claw 320. The connecting portion 302 is connected to a lifting drive component 303, and a guide rod 304 is also provided between the lifting drive component 303 and the connecting portion 302. The lifting drive component 303 drives the connecting portion 302 to rise and fall along the guide rod 304, and drives the support portion 301 to enter and exit the cleaning tank 200, thereby improving the lifting stability and thus improving the cleaning reliability.

[0051] In one embodiment, the telescopic drive member 410 is disposed close to the cleaning tank 200, and the drive end of the telescopic drive member 410 is away from the cleaning tank 200. The cleaning rod 420 is disposed parallel to the drive end of the telescopic drive member 410, and the two are connected by an end located on the same side, thereby effectively controlling the length of the telescopic cleaning mechanism 400 and thus controlling the volume of the device.

[0052] In one embodiment, a nozzle 430 is provided at the end of the cleaning rod 420 near the cleaning tank 200, and the nozzle 430 is located inside the cleaning tank 200 and can move under the drive of the cleaning rod 420, that is, move along the length direction of the rotating drum 10, thereby improving the cleaning effect.

[0053] In one embodiment, the cleaning rod 420 is provided with bristles in the circumferential direction to improve the cleaning effect.

[0054] In one embodiment, the supporting surface of the second claw 320 is higher than the supporting surface of the first claw 310, and the supporting drum 10 is tilted at a 4°-7° angle, such as 4°, 5°, 6.5°, so as to balance the waste liquid diversion effect and the bearing stability and reliability of the drum 10.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
