Description

Technical Field

[0001] This utility model relates to the field of centrifuges, specifically a flat-plate centrifuge with a protective structure. Background Technology

[0002] A flat-plate centrifuge is an industrial device used for solid-liquid separation. Its core feature is that it uses a flat-plate base instead of the traditional three-legged structure to achieve efficient separation through centrifugal force. However, in existing flat-plate centrifuges, the pulleys and drive shafts at the bottom of the plate are only protected by a single protective cover. After an impact, the single protective cover is prone to deformation, which may lead to damage to the internal pulleys and drive shafts. This requires disassembling the protective cover to repair the pulleys and drive shafts, which greatly reduces the service life of the centrifuge.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN211246978U discloses a flat-plate centrifuge with a protective structure. Through this designed structure, when the bottom of the flat plate is struck by an external object during use or transport, the buffer spring and protective net act as a buffer, completely absorbing the impact force or reducing the impact force transmitted to the protective cover, thus preventing damage to the pulleys and drive shaft. This protective structure provides dual protection for the pulleys and drive shaft, reducing their maintenance rate and extending the centrifuge's service life.

[0004] While the comparative patent solved the problem of needing to disassemble the protective cover to repair the pulley and drive shaft, which greatly reduced the service life of the centrifuge, the spring stiffness in the device gradually decreases over time, thus reducing the lifespan of the device's protective function.

[0005] Regarding the aforementioned technologies, the spring stiffness in this device gradually decreases over time, thus reducing the lifespan of the device's protective function. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a flat-plate centrifuge with a protective structure. This centrifuge has the advantages of ensuring that the protective effect of the device does not gradually decline over time, thus extending the lifespan of the protective function. It also solves the problem that the spring stiffness in the device gradually declines over time, thereby reducing the lifespan of the protective function.

[0007] To ensure that the protective effect of the device does not gradually decline over time and thus extend the lifespan of its protective function, this utility model provides the following technical solution: a flat-plate centrifuge with a protective structure, comprising a centrifuge body, a base plate fixedly connected to the bottom of the centrifuge body, a support component provided at the bottom of the base plate, a buffer airbag fixedly connected to the bottom of the base plate, a branch airbag fixedly connected to the inner wall of the buffer airbag, an air block fixedly connected to both ends of the branch airbag, an air hole provided inside the air block, and a ventilation component provided inside the air hole.

[0008] As a preferred embodiment of this utility model, the support component includes a support leg, a support column is fixedly connected to the top of the support leg, and a first spring is fixedly connected to the inner bottom wall of the support column.

[0009] As a preferred embodiment of this utility model, a support rod is fixedly connected to the top of the first spring, the outer wall of the support rod is connected to the inside of the support column, and the top of the support rod extends to the outside of the support column.

[0010] As a preferred embodiment of this utility model, one end of the support rod extending to the outside of the support column is fixedly connected to the bottom of the base plate.

[0011] As a preferred embodiment of this utility model, a mesh plate is fixedly connected to the inner wall of the ventilation component, a second spring is fixedly connected to one side of the mesh plate, a sealing block is fixedly connected to one end of the second spring, and the outer wall of the sealing block is slidably connected to the inner wall of the through groove.

[0012] As a preferred embodiment of this utility model, the inner wall of the through groove is inclined, and the sealing block has the same shape as the through groove.

[0013] Compared with the prior art, this utility model provides a flat-plate centrifuge with a protective structure, which has the following beneficial effects: 1. After the base plate is subjected to external gravity, the buffer airbag compresses the gas, which then enters the branch airbag. Since the inner wall of the channel is inclined, when the sealing block moves towards the mesh plate under the impact of the gas, a gap will be left between the outer wall of the sealing block and the inner wall of the channel. The gas will then flow out through the gap between the sealing block and the inner wall of the channel, allowing the gas inside the buffer airbag to enter the branch airbag. The branch airbag can protect the central component of the base plate. The outer wall of the buffer airbag is equipped with a one-way air inlet valve. When the gas inside the buffer airbag is lost, the gas can be injected into the buffer airbag through the one-way air inlet valve by an external air pump, thus enabling long-term use. The protective effect of this device will not gradually decline with the use time, thereby extending the life of the protective function of the device.

[0014] 2. A mesh plate is fixedly connected to the inner wall of the ventilation component. When the sealing block is subjected to the impact force of gas, the sealing block will move towards the mesh plate, thereby compressing the second spring. The surface of the mesh plate is a grid, which can play a role in ventilation, allowing the gas inside the buffer airbag to enter the interior of the branch airbag. The branch airbag can protect the central component of the base plate, thereby further meeting the usage requirements of the device and improving its practicality. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0018] Reference Figure 1-3 The first embodiment of this utility model provides a flat plate centrifuge with a protective structure, including a centrifuge body 1, a base plate 6 fixedly connected to the bottom of the centrifuge body 1, a support component provided at the bottom of the base plate 6, a buffer airbag 7 fixedly connected to the bottom of the base plate 6, a branch airbag 8 fixedly connected to the inner wall of the buffer airbag 7, and an air block 9 fixedly connected to both ends inside the branch airbag 8. The air block 9 has an air hole inside, and a ventilation component is provided inside the air hole.

[0019] Reference Figure 1-3 The supporting components include a support leg 2, a support column 3 is fixedly connected to the top of the support leg 2, and a first spring 4 is fixedly connected to the inner bottom wall of the support column 3. The support leg 2 can play a supporting role, thereby supporting the base plate 6 and the centrifuge body 1.

[0020] Furthermore, a support rod 5 is fixedly connected to the top of the first spring 4. The outer wall of the support rod 5 is connected to the inside of the support column 3, and the top of the support rod 5 extends to the outside of the support column 3. The support rod 5 can press the first spring 4. When the first spring 4 is compressed, one end of the support rod 3 can move to the inside of the support column 3.

[0021] Furthermore, one end of the support rod 5 extends to the outside of the support column 3 and is fixedly connected to the bottom of the base plate 6. Thus, when the base plate 6 is subjected to external impact, the distance between the support rod 5 and the support column 3 will shrink, thereby preventing damage to the support leg 2.

[0022] Reference Figure 1-3 A mesh plate 11 is fixedly connected to the inner wall of the ventilation component. A second spring 12 is fixedly connected to one side of the mesh plate 11. A sealing block 13 is fixedly connected to one end of the second spring 12. The outer wall of the sealing block 13 is slidably connected to the inner wall of the through groove 10. When the sealing block 13 is subjected to the impact force of gas, the sealing block 13 will move towards the mesh plate 11, thereby compressing the second spring 12. The surface of the mesh plate 11 is a mesh, which can play a role in ventilation.

[0023] Furthermore, the inner wall of the through groove 10 is inclined, and the sealing block 13 has the same shape as the through groove 10. Since the inner wall of the through groove 10 is inclined, when the sealing block 13 is impacted by gas and moves towards the mesh plate 11, a gap will be left between the outer wall of the sealing block 13 and the inner wall of the through groove 10. As a result, the gas will flow out through the gap between the sealing block 13 and the inner wall of the through groove 10, so that the gas inside the buffer airbag 7 can enter the interior of the branch airbag 8. The branch airbag 8 can protect the central component of the base plate 6.

[0024] During use, after the base plate 6 is subjected to external gravity, the buffer airbag 7 will compress the gas under gravity and then enter the interior of the branch airbag 8. Since the inner wall of the through groove 10 is inclined, when the sealing block 13 moves towards the mesh plate 11 under the impact of the gas, a gap will be left between the outer wall of the sealing block 13 and the inner wall of the through groove 10. The gas will flow out through the gap between the sealing block 13 and the inner wall of the through groove 10, so that the gas inside the buffer airbag 7 can enter the interior of the branch airbag 8. The branch airbag 8 can protect the central component of the base plate 6. The outer wall of the airbag 7 is equipped with a one-way air intake valve. When the gas inside the airbag 7 is lost, the gas can be injected into the airbag 7 through the one-way air intake valve by an external air pump, so that it can be used for a long time.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
