Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following description and the drawings are provided only to facilitate a general understanding of the present invention, and the technical scope of the present invention is not limited to the embodiments. A detailed description of known structures or functions that may unnecessarily obscure the subject matter of the present invention will be omitted below.
Fig. 2 is a diagram showing the outer shape of the multi-functional ventilator of the present invention. Fig. 3 is a cut-away perspective view of the multi-functional ventilator shown in fig. 2 according to an embodiment of the present invention, and fig. 4 is an internal sectional view of an embodiment of the present invention.
The present invention comprises an outer cylinder 100, an intermediate cylinder 200, an inner cylinder 300, a desiccant 400, an adsorbent 500, a cover 600, a base 700, and a check valve 800, and is connected to an oil tank to allow external air to flow into the oil tank or to discharge oil vapor generated in the oil tank.
First, the outer cylinder 100 forms an outer shape of the present invention, and the middle cylinder 200 and the inner cylinder 300 are accommodated therein.
The middle cylinder 200 is installed inside the outer cylinder 100 and can accommodate the inner cylinder 300 therein. A cover 220 is installed on the upper side of the middle cylinder 200 to seal the upper portion of the middle cylinder 200, and the check valve 800 is installed at the center of the cover 220.
Here, the middle cylinder 200 is installed inside the outer cylinder 100 such that external air passes between the outer cylinder 100 and the middle cylinder 200.
The inner cylinder 300 is installed inside the middle cylinder 200 and positioned at a lower portion of the check valve 800.
Further, since a passage for connecting the inner cylinder 300 is formed at the upper side of the middle cylinder 200, the oil vapor moves between the middle cylinder 200 and the inner cylinder 300 through the passage in the inner cylinder 300. Here, the passage is a gap generated by a difference in length between a lower side of the cap 220 mounted on the middle cylinder 200 and an upper side of the inner cylinder 300.
The desiccant 400 is installed between the outer cylinder 100 and the middle cylinder 200 to remove moisture from the inflow external air. Here, the desiccant 400 is preferably Silica Gel, and other desiccant may be used.
The adsorbent 500 is installed between the middle cylinder 200 and the inner cylinder 300 to remove oil. Here, it is preferable to use activated Carbon (Active Carbon) having a large surface area and strong adsorbability and capable of adsorbing oil components of oil vapor, but other adsorbents may be used.
The cover 600 is installed on the upper portion of the outer cylinder 100 to form an inner space, so that the upper portion of the outer cylinder 100 is connected to the upper portion of the inner cylinder 300. Here, the upper plate 620 is mounted between the cover 600 and the outer cylinder 100, and the cover 600 and the outer cylinder 100 can be easily fastened. Further, a metal mesh net 640 is provided between the upper plate 620 and the cover 600 to filter out foreign substances in the inflow external air.
The base 700 is installed at a lower portion of the outer cylinder 100 and is connected to an oil tank at a lower side thereof. When the base 700 is coupled to the lower portion of the outer cylinder 100, the lower plate 710 is installed therebetween, and thus the outer cylinder 100 and the base 700 can be easily fastened. Further, a metal mesh net 720 is provided between the lower plate 710 and the base 700 to filter out foreign substances contained in the inflow external air.
The base 700 is formed with an air flow inlet 730, an oil vapor inflow port 740, and an oil vapor discharge port 750. The air inlet 730 is formed vertically penetrating the base 700 so that external air can flow between the outer cylinder 100 and the middle cylinder 200. Here, a check valve 900 is attached to the air inlet 730, and the check valve 900 is opened when the oil level of the oil tank is lowered. The oil vapor inflow port 740 is formed vertically penetrating the base 700 so that the oil vapor generated in the oil tank passes through the inner cylinder 300. The oil vapor discharge port 750 is formed vertically penetrating the base 700 so that the oil vapor passing between the middle cylinder 200 and the inner cylinder 300 can be discharged to the outside. A check valve 1000 is attached to the oil vapor discharge port 750 and is opened when the oil level of the oil tank becomes high.
On the other hand, since the performance of the ventilator is deteriorated when the pressure in the ventilator is in a vacuum state, it can be confirmed that the inside of the multi-functional ventilator is in a vacuum state due to the fact that the manual vacuum pressure indicator 760 connected to the oil vapor inflow port 740 is attached to the base 700.
Further, a vacuum pressure sensor 980 is installed in the cover 600, and a microprocessor chip 940 receives a signal from the vacuum pressure sensor 980, and displays the signal on the light emitting diode window 960 in a light emitting manner by the light emitting diode LED when the vacuum pressure is approached, thereby confirming that the inside of the multi-functional ventilator is in a vacuum state and a failure state is caused.
Therefore, the cover 600 is dualized without a Printed Circuit Board (PCB)990 as a specification suitable only for the manual vacuum pressure display device.
The check valve 800 is installed at the upper portion of the inner cylinder 300, and the external air passing between the outer cylinder 100 and the middle cylinder 200 flows through the inner cylinder 300 through the check valve 800 and then flows into the oil tank.
The check valve 800 is installed at an upper portion of the inner cylinder 300 to prevent oil vapor generated from the oil tank from passing therethrough.
The cover 600 is provided with a humidity sensor 920 for measuring the humidity of the outside air passing through the desiccant 400, and a light emitting diode window 960 for displaying the humidity by a Light Emitting Diode (LED) and diffusing the light of the LED after being sensed by a microprocessor chip 940 in response to a signal input from the humidity sensor 920. That is, when the humidity of the outside air passing through the desiccant 400 is equal to or higher than a predetermined value, the humidity can be displayed by emitting light to the outside through the light emitting diode window 960. That is, even if the dehumidifying agent 400 uses various dehumidifying agents other than Silica Gel (Silica Gel) according to the use environment, the replacement timing can be easily known.
Fig. 5 is a graph showing the flow of outside air of the embodiment of the present invention.
The flow of the outside air is explained below with reference to fig. 5.
First, the flow of outside air when the height of oil in the tank is lowered is as follows.
The check valve 900 installed at the base 700 is opened and the external air passes through the desiccant 400 between the outer cylinder 100 and the middle cylinder 200 to remove moisture. Then, the moisture-removed outside air moves into the inner cylinder 300 through the check valve 800 in the cover 600 and flows into the oil tank T.
Fig. 6 is a graph showing the flow of oil vapor of the embodiment of the present invention.
Referring to fig. 6, when the oil level inside the oil tank T becomes high, the pressure of the air and the oil vapor inside increases. At this time, it is necessary to discharge the oil vapor to the outside, and the flow of the oil vapor is described below.
The oil vapor generated from the oil tank T passes through the inner cylinder 300 and then moves between the middle cylinder 200 and the inner cylinder 300 through a passage formed in the middle cylinder 200. The oil vapor is purged by the adsorbent 500 installed inside the middle cylinder 200 and the inner cylinder 300, and then discharged through the oil vapor discharge port 750 by opening the check valve 1000.
The present invention described above is not limited to the above-described embodiments, and various modifications which can be implemented by those skilled in the art without departing from the gist of the present invention claimed in the claims should be construed as belonging to the scope of the present invention.
