Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a centrifuge that is easy to replace and maintain. Background Technology

[0002] Centrifuges are indispensable solid-liquid separation equipment in chemical, pharmaceutical, and food processing industries. Their core working components generate a centrifugal force field through high-speed rotation, achieving precise separation of substances with different densities. The stability of equipment operation and ease of maintenance directly affect production efficiency and operational safety. Among them, the centrifuge tank, as the core component that carries the material for separation, is in a state of high-speed operation for a long time and is prone to failure due to material corrosion, dynamic imbalance, or bearing wear. Regular maintenance or replacement is required to avoid safety accidents such as violent resonance of the equipment, sample leakage, or even rotor detachment caused by component failure.

[0003] Chinese patent CN223570940U discloses a horizontal centrifuge that is easy to maintain. The device uses a limiting component in the fixed parts to limit the insertion rod, keeping the insertion rod separated from the connecting pin. Then, the remaining fixed parts can be operated. The outer shell can be quickly disassembled without the need to remove multiple bolts with tools, which facilitates internal maintenance. At the same time, the inclusion of casters in the movable parts makes the outer shell easier to move and separate from the connecting shell. However, the disassembly and maintenance process requires a large number of parts to be disassembled and installed, which takes up a lot of time. Therefore, a centrifuge that is easy to replace and maintain is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a centrifuge that is easy to replace and maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A centrifuge that is easy to replace and maintain includes a front frame centrifuge, on which a drive rod centrifuge is mounted, and a centrifuge drum centrifuge is connected to the drive rod centrifuge. A centrifuge with a limit bearing is also connected to the outside of the centrifuge drum centrifuge. Guide frame centrifuges are also provided on both sides of the centrifuge drum centrifuge. A rear frame centrifuge is provided on one side of the front frame centrifuge, and a main motor centrifuge and a drive disc centrifuge are mounted on the rear frame centrifuge.

[0006] Preferably, a drive belt centrifuge is connected between the output end of the main motor centrifuge and the drive disc centrifuge. Two sets of drive rod centrifuges are provided, both symmetrically installed inside the front frame centrifuge of the device. Each drive rod centrifuge is provided with multiple drive rings. One end of one drive rod centrifuge is connected to the center of the drive disc centrifuge. Multiple second cylinder centrifuges are also mounted on the bottom side of the front frame centrifuge of the device. A push plate centrifuge is installed on the telescopic end of the second cylinder centrifuge. The push plate centrifuge is movably connected between the two sets of drive rod centrifuges and is connected to the bottom surface of the centrifuge drum centrifuge.

[0007] Preferably, the centrifuge barrel has a feed inlet on one side, and an annular groove is formed on the outer surface of the centrifuge barrel. The drive ring is connected in the annular groove, and the two are in a frictional connection.

[0008] Preferably, two first-cylinder centrifuges are installed on one side of the front frame centrifuge of the device, and a feeding frame centrifuge is installed between the telescopic ends of the first-cylinder centrifuges. The feeding frame centrifuge is equipped with a feeding hopper and an inclined material pipe, and one end of the inclined material pipe is connected to the feeding port.

[0009] Preferably, the guide frame centrifuge is mounted on the front frame centrifuge of the device, and multiple guide rods are installed on the guide frame centrifuge. The guide rods correspond to the positions of the annular grooves on the centrifuge drum centrifuge, and the centrifuge drum centrifuge is rotatably connected to the guide frame centrifuge.

[0010] Preferably, the device has a frame centrifuge mounted on the front frame centrifuge, a second motor centrifuge mounted on the top surface of the frame centrifuge, an eccentric wheel centrifuge connected to the output end of the second motor centrifuge, a support frame centrifuge mounted on the bottom surface of the frame centrifuge, a lifting rod centrifuge movably connected inside the support frame centrifuge, a spring connection between the top end of the lifting rod centrifuge and the support frame centrifuge, two limit bearing centrifuges symmetrically mounted on the bottom end of the lifting rod centrifuge, the limit bearing centrifuges connected in an annular groove, a fixing plate mounted on the top end of the lifting rod centrifuge, and the eccentric wheel centrifuge connected to the top surface of the fixing plate.

[0011] The beneficial effects of this utility model are: This design uses a main motor to drive a drive rod to rotate, which in turn drives the centrifuge drum to rotate. The use of limit bearings allows for easy positioning of the centrifuge drum, preventing it from shifting during rotation. The feed rack facilitates the entry of materials into the centrifuge drum and can be moved to avoid contact during drum replacement.

[0012] This solution reduces the possibility of spending a lot of time disassembling the equipment during maintenance, reduces the time spent on equipment maintenance, improves the efficiency of quickly replacing centrifuge tanks, and also improves the overall working efficiency of the equipment, greatly reducing equipment downtime.
