Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a waterproof ring used in centrifuges. Background Art

[0002] A centrifuge is a device that automatically discharges solid-liquid mixtures by separating them. Usually, the centrifuge drum includes a straight section and a conical section that are connected to each other, and the slag discharge port is usually located at the small end of the conical section. When the material is fed into the drum through a feed pipe, the solid and liquid phases will separate under the action of centrifugal force. The upper liquid flows out of the drum, and the lower solid settles and adheres to the inner wall of the drum. It is pushed from the straight section of the drum to the conical section by the spiral, and is thrown out of the drum after reaching the slag discharge port, thus achieving solid-liquid separation.

[0003] In order to prevent liquid from flowing out of the connection between the drum and the hood, a waterproof ring is used. For example, in the patent application with publication number CN 219043396 U in the prior art, a water retaining portion is formed by obliquely extending the outer side of the main body, and the water retaining portion is elastic. The utility model also discloses a centrifuge, including a drum, the drum is provided with a liquid discharge port, and the end of the drum provided with the liquid discharge port is provided with a waterproof ring applied to the centrifuge as described above. Its beneficial effects are: when the centrifuge is in an unused shutdown state, the water retaining portion abuts against the hood to ensure the waterproof effect. When the centrifuge is started and starts working in the on state, the abutment between the waterproof ring and the hood is released due to the centrifugal force generated by the rotation, avoiding the wear caused by the friction generated by the rotation, so it is durable and has a good waterproof effect, and the installation is simple while reducing the cost.

[0004] When the waterproof ring is in use, the elasticity of the water retaining part presses against the casing, thereby achieving a sealing effect. However, after long-term use, the elasticity of the water retaining part is easily reduced, thereby reducing the waterproof effect.

[0005] Therefore, it is necessary to provide a waterproof ring for centrifuge to solve the above technical problems. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0026] First embodiment

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a waterproof ring applied to a centrifuge provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the conical sheet structure shown; Figure 3 for Figure 1 The schematic diagram of the chassis structure shown; Figure 4 for Figure 1 The schematic diagram of the side cross-sectional structure of the clamping block is shown. A waterproof ring used in a centrifuge comprises: a chassis 1 and a mounting ring 2;

[0028] A first reinforcing ring 11, wherein the first reinforcing ring 11 is fixedly mounted on the top of the chassis 1, and a groove 12 is formed at the bottom of the chassis 1, and a magnetic sheet 13 is disposed at the bottom of the inner side of the groove 12;

[0029] The second reinforcing ring 21 is fixedly mounted on the top of the mounting ring 2, a conical piece 22 is fixedly mounted on the outer side of the mounting ring 2, a plurality of clamping blocks 24 are fixedly mounted on the edge of the bottom of the conical piece 22, and a metal block 25 is arranged inside each of the plurality of clamping blocks 24.

[0030] A limiting groove 23 is formed at the bottom of the installation ring 2 , and the limiting groove 23 is arranged at the top of the first reinforcement ring 11 .

[0031] The outer diameter of the first reinforcement ring 11 matches the inner diameter of the limiting groove 23 .

[0032] The clamping block 24 is in an arc shape.

[0033] The conical piece 22 is disposed on the top of the chassis 1 , and the clamping block 24 is disposed on the top of the groove 12 .

[0034] The clamping block 24 is matched with the groove 12 .

[0035] A plurality of the clamping blocks 24 are provided, so that magnetic force can be generated between the metal blocks 25 provided inside the plurality of clamping blocks 24 and the magnetic sheet 13, thereby pulling the conical sheet 22 downward.

[0036] The working principle of a waterproof ring applied to a centrifuge provided by the utility model is as follows:

[0037] When in use, the user sleeves the first reinforcing ring 11 on the casing, and then sleeves the second reinforcing ring 21 and the mounting ring 2 on the outer side of the drum, and makes the conical piece 22 at the bottom of the water outlet of the drum. When the drum does not rotate, the clamping block 24 installed at the bottom of the conical piece 22 is clamped on the inner side of the groove 12, so that the metal block 25 and the magnetic piece 13 are magnetically attracted. When the drum rotates, it will drive the mounting ring 2 and the conical piece 22 to rotate. At this time, due to the centrifugal force, the conical piece 22 will open to the outer side, so that the clamping block 24 will move out from the inner side of the groove 12, so that the metal block 25 and the magnetic piece 13 will cancel the magnetic attraction. In this way, the bottom of the conical piece 22 is away from the top of the chassis 1, so as to avoid friction between the conical piece 22 and the chassis 1, causing damage to the conical piece 22 and the chassis 1;

[0038] When the drum stops rotating, the conical piece 22 will move downward again due to gravity. At this time, the bottom of the conical piece 22 is attached to the top of the chassis 1, thereby playing a sealing role. At the same time, the metal block 25 and the magnetic piece 13 are magnetically attracted to limit the clamping block 24 to the inner side of the groove 12, and the conical piece 22 moves downward.

[0039] Compared with the related art, the waterproof ring used for centrifuge provided by the utility model has the following beneficial effects:

[0040] Through the cooperation of the groove 12, the magnetic sheet 13, the snap-fit ​​block 24, the metal block 25 and the conical sheet 22, when in use, the magnetic sheet 13 can magnetically attract the snap-fit ​​block 24, so that when the drum stops rotating, the magnetic force generated between the magnetic sheet 13 and the metal block 25 can drive the bottom of the conical sheet 22 to fit against the top of the chassis 1, thereby increasing the waterproof effect and avoiding the reduction of the elasticity of the conical sheet 22 and the reduction of the sealing effect due to the aging of the conical sheet 22.

[0041] Second embodiment

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the waterproof ring for a centrifuge provided in the second embodiment of the present application is different in that, in the waterproof ring for a centrifuge, a plurality of counterweights 3 are fixedly mounted on the edge of the top of the conical piece 22 .

[0044] The working principle of a waterproof ring applied to a centrifuge provided by the utility model is as follows:

[0045] When in use, a plurality of counterweights 3 are installed on the outer edge of the top of the conical piece 22. When the conical piece 22 rotates along with the drum, the counterweights 3 are driven to move outward due to the centrifugal force, thereby expanding the conical piece 22 to avoid friction between the bottom of the conical piece 22 and the top of the chassis 1, thereby causing wear and damage to the conical piece 22 and the chassis 1.

[0046] Compared with the related art, the waterproof ring used for centrifuge provided by the utility model has the following beneficial effects:

[0047] By installing multiple counterweights 3 on the top of the conical piece 22, when the conical piece 22 is in use, it can drive the counterweights 3 to move toward the edge when it rotates, so that the bottom of the conical piece 22 is away from the top of the chassis 1, avoiding friction between the bottom of the conical piece 22 and the top of the chassis 1, causing damage to the conical piece 22 and the chassis 1.

[0048] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
