Description

Supergravity device with liquid blocking ring wall

The present invention relates to a supergravity device, in particular to a supergravity device with a liquid blocking ring wall.

Existing devices that use rotating shafts (such as rotating packed bed reactors, axial flow pumps) are air-tightly sealed, and mechanical shaft seals (such as cartridge seals) are generally used. )], that is, using mechanical elements such as oil seals, springs, or blades to achieve air-sealing resistance. However, the seals in the above devices will gradually wear out over time and create gaps. When applied to a supergravity device, it is easy to cause the mechanical components to be exposed to the liquid inside the supergravity device or the gas containing a large amount of liquid mist (such as water mist). The lubricating oil ester that penetrates into the gap and contaminates the oil seal will increase the friction when the bearing rotates and produce rust, thus causing the risk of bearing damage.

Therefore, the purpose of the present invention is to provide a supergravity device with a liquid-blocking ring wall, which can avoid the above-mentioned problems that are prone to occur in the prior art.

Therefore, the super-gravity device with the liquid blocking ring wall of the present invention includes a housing, a bearing seat, a rotating shaft and a rotating bed unit. The shell includes a shell base wall and a shell surrounding wall. The bearing seat penetrates through the base wall of the shell. The rotating shaft is rotatably pierced through the bearing seat by a movable seal. The rotating bed unit is arranged in the housing and spaced apart from the housing, and the rotating bed unit includes a substrate, a filling layer and a liquid blocking ring wall. The substrate is connected to the rotation shaft. The filling layer extends from the substrate in a direction opposite to the bearing seat. The liquid blocking ring wall extends from the base plate toward the housing base wall and surrounds the bearing seat adjacently and at intervals, and cooperates with the base plate to define a liquid blocking space therebetween.

The effect of the present invention is that the super-gravity device with the liquid blocking ring wall of the present invention can effectively prevent the liquid or liquid-containing mist from contacting the dynamic seal or penetrating into the gap to contaminate the lubricating oil, and even causing the risk of bearing damage.

The content of the present invention will be described in detail below:

Preferably, the supergravity device with the liquid-blocking ring wall of the present invention further includes an air inlet duct extending from the outside of the housing to the liquid-blocking space for introducing a gas into the liquid-blocking space.

Preferably, the super-gravity device with a liquid-blocking ring wall of the present invention further includes a measuring tube that communicates the liquid-blocking space with a pressure gauge to measure the gas pressure in the liquid-blocking space.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

The present invention will be further described in the following embodiments, but it should be understood that the embodiments are only for illustrative purposes and should not be construed as limitations on the implementation of the present invention.

Referring to FIG. 1, an embodiment of a supergravity device with a liquid blocking ring wall of the present invention includes a housing 1, a bearing seat 2, a rotating shaft 3, a rotating bed unit 4, an air inlet duct 5 and a measuring tube 7 .

The housing 1 includes a housing base wall 11, a housing surrounding wall 12 and an auxiliary ring wall 13. The housing base wall 11 has a liquid outlet 111 for a liquid to flow out of the housing 1. The casing surrounding wall 12 has an air inlet 121 for introducing a gas into the casing 1.

The bearing housing 2 penetrates through the base wall 11 of the housing.

The rotating shaft 3 rotatably penetrates the bearing housing 2 via a movable seal 6. In this embodiment, the dynamic seal 6 is an oil seal.

The rotating bed unit 4 is arranged in the housing 1 and spaced apart from the housing 1. The rotating bed unit 4 includes a base plate 41, a filling layer 42 and a liquid blocking ring wall 43. The base plate 41 is connected to the rotating shaft 3. The filling layer 42 extends from the base plate 41 in a direction opposite to the bearing housing 2. The liquid blocking ring wall 43 extends from the base plate 41 toward the housing base wall 11 to be adjacent to the housing base wall 11, and adjacently surrounds the bearing housing 2 at intervals, and cooperates with the base plate 41 to define a liquid barrier therebetween Space 430. The auxiliary ring wall 13 of the housing 1 extends from the housing base wall 11 toward the base plate 41 and surrounds the liquid blocking ring wall 43 adjacently and at intervals, and is arranged coaxially with the liquid blocking ring wall 43. The auxiliary ring wall 13 has a drain hole 131 adjacent to the housing base wall 11.

In this embodiment, the housing base wall 11 is non-planar, and the distance from the housing base wall 11 to the base plate 41 gradually increases as the bearing housing 2 moves toward the housing surrounding wall 12.

The air inlet duct 5 extends from the outside of the housing 1 to the liquid barrier space 430 for introducing a gas into the liquid barrier space 430.

The measuring tube 7 communicates with the liquid-blocking space 430 and a pressure gauge to measure the gas pressure in the liquid-blocking space 430.

When the rotating shaft 3 is driven externally to rotate so that the rotating bed unit 4 rotates relative to the casing 1, liquid and gas containing a large amount of liquid mist (such as water mist) are splashed by the filling layer 42 and filled in the casing 1 . At the same time, the liquid contacting the liquid blocking ring wall 43 will be subjected to the centrifugal force generated by the rotation, so as to prevent the liquid inside the housing 1 from splashing to the dynamic seal 6 of the bearing housing 2. At the same time, the gas in the liquid blocking space 430 is also driven by centrifugal force to rotate, which prevents the gas containing a large amount of liquid mist (such as water mist) inside the housing 1 from entering the liquid blocking space 430. The auxiliary ring wall 13 surrounding the liquid blocking ring wall 43 can further enhance the above-mentioned blocking effect. The liquid drain hole 131 can discharge the liquid accumulated inside the auxiliary ring wall 13 to the outside of the auxiliary ring wall 13.

The high-gravity device of this embodiment can also introduce gas (such as air, gas with a relative humidity of less than 70%, low-temperature gas) into the liquid barrier space 430 through the intake duct 5, thereby generating a greater gas pressure , It can further prevent the gas containing a large amount of liquid mist (such as water mist) inside the housing 1 from entering the liquid barrier space 430, thereby avoiding liquid infiltration into the gap of the dynamic seal 6 and effectively preventing the lubricating oil in the oil seal from being affected. The contamination of the liquid mist or the risk of bearing damage can also produce cooling and heat dissipation effects on the bearing seat 2 to increase the service life of the dynamic seal 6 and the bearing.

In addition, if fluid accumulates inside the supergravity device, the gas in the liquid barrier space 430 will be squeezed, and the pressure gauge connected to the measuring tube 7 will measure the gas pressure to rise, which can warn that the liquid is about to come into contact with the gas. The case of the movable seal 6.

To sum up, the ultra-gravity device with liquid barrier ring wall of the present invention can effectively prevent liquid or gas containing a large amount of liquid mist from penetrating into the dynamic seal through the arrangement of the liquid barrier ring wall 43 and defining the liquid barrier space 430. The gap of the member 6 prevents the lubricant ester in the oil seal from being contaminated and even the risk of bearing damage, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
