Description

Technical Field

[0001] This utility model relates to the field of centrifugal separation equipment technology, and in particular to a high-speed centrifuge. Background Technology

[0002] High-speed centrifuges, as important solid-liquid separation equipment, are widely used in various fields such as biology, medicine, and chemicals. These devices typically achieve material separation through centrifugal force generated by high-speed rotation, placing extremely high demands on the stability and ease of operation of the equipment.

[0003] In existing technologies, centrifuges typically use numerous bolts, flanges, or other traditional fasteners to connect and seal the drum cover to the main casing to ensure safety and sealing during high-speed rotation. While this connection method is structurally reliable, it has revealed significant shortcomings in practical production applications. When routine maintenance, cleaning, or replacement of internal components is required, workers must loosen and disassemble these fasteners one by one, consuming considerable time and manpower. Especially when handling viscous or corrosive materials, the frequent and tedious disassembly and assembly process reduces equipment maintenance efficiency and extends downtime.

[0004] Therefore, this utility model proposes a high-speed centrifuge to solve the shortcomings of the prior art, such as low efficiency in disassembling and assembling the drum cover and unreliable adjustment and fixing of the internal disc spacing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-speed centrifuge, which aims to improve the problems of existing high-speed centrifuges, such as the drum cover being connected by traditional fasteners such as bolts, resulting in cumbersome disassembly and assembly processes, low maintenance efficiency, and inconvenient adjustment and unreliable fixing of the axial spacing of the internal disc assembly.

[0006] To achieve the above objectives, this utility model provides a high-speed centrifuge, comprising: a base, a casing, a drum cover, a disc, a second fixing column; as well as a quick-release assembly and an adjustment assembly.

[0007] The housing is fixedly connected to the top of the base, and the base supports the housing through the bottom of the housing. The drum cover is detachably sealed to the top of the housing, the second fixing post is disposed inside the housing, and the disc is sleeved on the second fixing post.

[0008] The quick-release assembly includes a hook, a fixing bracket, a pin, a first screw, a first fixing post, a locking lever, a mounting plate, and a connecting post.

The locking lever is rotatably connected to the mounting plate via the connecting post, and the first fixing post is rotatably connected to the locking lever. The first screw is fixedly connected to the top of the first fixing post. The fixing bracket is rotatably connected to the upper end of the first screw via the pin, and the fixing bracket can be detachably engaged with the hook.

[0009] Preferably, the adjusting assembly includes a connecting ring, a locking ring, and at least two limiting rings. The connecting ring is coaxially sleeved on the outer wall of the second fixing post, and the disc is axially positioned between the two limiting rings. The locking ring is sleeved on the outer wall of the connecting ring and is used to apply a radial clamping force to the connecting ring.

[0010] Preferably, the locking ring applies a clamping force to the connecting ring in the radial direction, causing friction between the connecting ring and the second fixing post, thereby achieving axial fixation of the disc.

[0011] Preferably, the adjusting assembly further includes a first fixing block, a second fixing block, and a second screw. Both the first fixing block and the second fixing block are fixedly connected to the outer wall of the locking ring. The second screw is threaded between the first fixing block and the second fixing block, and rotation of the second screw drives the locking ring to tighten or loosen.

[0012] Preferably, the adjustment assembly further includes a rotating block. The rotating block is fixedly connected to one end of the second screw and is used to receive the drive of an external tool.

[0013] Preferably, one end of the rotating block is provided with a cross-shaped groove to facilitate the access of external tools and the transmission of torque.

[0014] Preferably, the connecting post is located on the left side of the locking lever, and the first fixing post is located on the right side of the locking lever. This structure enhances the effort-saving effect when operating the quick-release assembly.

[0015] Preferably, the second screw is located on the left side of the rotating block.

[0016] Preferably, the base provides support to the housing by being fixed to the bottom of the housing.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a quick-release assembly consisting of a hook, a fixing frame, a first screw and a locking lever, the problem of the prior art requiring the use of bolts and other fasteners for disassembling and assembling the drum cover and the machine housing, resulting in cumbersome operation and low maintenance efficiency, is solved. This achieves the effect of quickly locking and unlocking the drum cover, greatly improving the efficiency of cleaning, maintenance and repair of the equipment.

[0018] 2. This utility model solves the problem of inconvenient adjustment or unstable fixing of the disc group spacing in the prior art by setting an adjustment component in which the first fixing block and the second fixing block are driven by the second screw to tighten the locking ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5This utility model provides a high-speed centrifuge, which aims to solve the problems of cumbersome disassembly and assembly of the drum cover, low locking reliability, and difficulty in adjusting the axial position of the internal discs and their unstable fixing in the prior art.

[0023] Specifically, it includes a base 3, a housing 2, a drum cover 1, a disc 5, and a second fixing post 6. The housing 2 is fixedly connected to the top of the base 3, and the base 3 supports the housing 2 through the bottom of the housing 2. The drum cover 1 is detachably sealed to the top of the housing 2. The second fixing post 6 is located inside the housing 2, and the disc 5 is sleeved on the second fixing post 6. The disc 5 is used to separate materials when the centrifuge rotates at high speed.

[0024] It also includes a quick-release assembly 4 and an adjustment assembly 7. The quick-release assembly 4 is used to quickly lock and release the drum cover 1 and the housing 2, and the adjustment assembly 7 is used to axially fix and adjust the disc 5 on the second fixing post 6.

[0025] The quick-release assembly 4 includes a hook 401, a fixing bracket 402, a pin 403, a first screw 404, a first fixing post 405, a locking lever 406, a mounting plate 407, and a connecting post 408. The hook 401 is fixedly connected to the bottom outer wall of the drum cover 1. The mounting plate 407 is fixedly connected to the upper outer wall of the housing 2. The locking lever 406 is rotatably connected to the mounting plate 407 via the connecting post 408, which is located to the left of the locking lever 406. The first fixing post 405 is rotatably connected to the locking lever 406 and is located to the left of the locking lever 406. On the right side of 6, the first screw 404 is fixedly connected to the top of the first fixed post 405, and the fixing frame 402 is rotatably connected to the upper end of the first screw 404 through the pin 403. The fixing frame 402 can be detachably engaged with the hook 401. By moving the locking lever 406, the first fixed post 405 and the first screw 404 are driven to swing using the connecting post 408 as the fulcrum, so that the fixing frame 402 and the hook 401 can be quickly engaged or disengaged, realizing the rapid locking and releasing of the drum cover 1. At the same time, rotating the first screw 404 can adjust the tension of the fixing frame 402.

[0026] The adjusting assembly 7 includes a connecting ring 701, a locking ring 702, and at least two limiting rings 707. The connecting ring 701 is coaxially sleeved on the outer wall of the second fixing post 6 with the disc 5. The disc 5 is axially positioned between the two limiting rings 707. The two limiting rings 707 are used to limit the axial stacking range of the disc 5 on the second fixing post 6. The locking ring 702 is sleeved on the outer wall of the connecting ring 701. The locking ring 702 applies a clamping force to the connecting ring 701, so that the connecting ring 701 clamps the second fixing post 6, thereby achieving axial fixation of the disc 5.

[0027] In a preferred embodiment, in order to reliably lock the connecting ring 701, the locking ring 702 applies a clamping force to the connecting ring 701 in the radial direction, so that the connecting ring 701 and the second fixing post 6 generate frictional force, thereby achieving axial fixation of the disc 5. This method of fixing by friction facilitates adjustment of the axial position of the disc 5.

[0028] In a preferred embodiment, to facilitate the application of clamping force by the locking ring 702, the adjusting assembly 7 further includes a first fixing block 703, a second fixing block 704, and a second screw 705. The first fixing block 703 and the second fixing block 704 are both fixedly connected to the outer wall of the locking ring 702. The locking ring 702 is preferably a C-shaped ring with an opening. The first fixing block 703 and the second fixing block 704 are respectively disposed on both sides of the opening of the locking ring 702. The second screw 705 is threaded through the first fixing block 703 and the second fixing block 704. By rotating the second screw 705, the distance between the first fixing block 703 and the second fixing block 704 can be adjusted, thereby changing the inner diameter of the locking ring 702 to apply or release radial clamping force.

[0029] In a preferred embodiment, to facilitate the rotation of the second screw 705, the adjusting assembly 7 further includes a rotating block 706, which is fixedly connected to one end of the second screw 705 and is located on the right side of the second screw 705.

[0030] As a preferred embodiment, in order to facilitate precise adjustment or apply greater locking force using tools, a cross-shaped groove is provided at one end of the rotating block 706, allowing the use of tools such as Phillips screwdrivers to assist in operating the rotating block 706.

[0031] As a preferred embodiment, in order to clarify the operating lever relationship of the quick-release component 4, the connecting post 408 is located on the left side of the locking lever 406 as the rotation fulcrum, and the first fixed post 405 is located on the right side of the locking lever 406 as the force application point, forming a force-saving lever structure that facilitates locking operation.

[0032] As a preferred embodiment, in order to ensure the overall stability of the high-speed centrifuge during operation, the base 3 supports the casing 2 through the bottom of the casing 2. The base 3 is preferably a counterweight structure with a large bottom area and weight to absorb the vibration generated during high-speed rotation.

[0033] Working principle: After the material enters from the top of the equipment, the drum cover 1 seals the internal space to ensure the sealing of the separation environment. The discs 5 are fixed inside the housing 2 by the second fixing column 6. Then the material flows into the separation area formed by the stacked discs 5. The discs 5 rotate at high speed inside the equipment, and the centrifugal force is used to separate materials of different densities. The entire separation process is carried out under the protection of the housing 2. The housing 2 plays the role of accommodating internal components and guiding the material in and out, while the base 3 is located at the bottom of the equipment to ensure the stability of the equipment when it is running at high speed. When disassembling and assembling the drum cover 1 and the housing 2, the quick-release assembly 4 is required. The hook 401 is fixed to the bottom outer wall of the drum cover 1, while the mounting plate 407 is fixed to the outer wall of the housing 2. The locking lever 406 and the mounting plate 407 are connected by the connecting column 408. The operator first lifts the locking lever 406 to drive the first fixing column 405 to rise. The movement of the first fixing column 405 drives the first screw 404 to move synchronously. Then, the first screw 404 and the fixing frame 402 are connected by the pin 403, which in turn drives the fixing frame 402 to move upward and disengage from the hook 401, thus completing the quick disassembly and assembly of the drum cover 1 and the housing 2. Adjusting the spacing of disc 5 requires the use of adjustment component 7. First, the limiting ring 707 is fitted onto the outer wall of the second fixing post 6. Then, disc 5 and connecting ring 701 are fitted onto the top of the limiting ring 707. Next, locking ring 702 is fitted onto the outer wall of connecting ring 701. A cross-shaped groove is provided at one end of rotating block 706. The rotating block 706 is then inserted into the groove using an electric drill, causing rotating block 706 and second screw 705 to rotate synchronously. The rotation of second screw 705 drives the first fixing block 703 fixed to the outer wall of locking ring 702. The second fixing block 704 generates axial displacement and tightens inward. During the tightening process, the locking ring 702 forms a uniform radial clamping force on the internal connecting ring 701, so that the gap between the connecting ring 701 and the second fixing post 6 is completely filled, thereby achieving a seal. Finally, the limiting ring 707 is fitted on the top of the connecting ring 701. The limiting ring 707 is fixed at both ends of the connecting ring 701 to prevent the disc 5 from sliding up and down during rotation. This completes the adjustment of the spacing of the disc 5 to meet the separation requirements of different materials.
