Description

Water separator with built-in sterilization function and auto drain}

The present invention relates to a water separator, and more specifically, to an improved water separator that separates moisture contained in compressed air, collects the separated moisture and automatically discharges it, and sterilizes the compressed air from which the moisture has been removed. This is about a water separator with a built-in sterilization function and auto-drain.

In the prior art, disclosed in Republic of Korea Patent No. 10-2104128, condensate is separated from compressed air and then discharged by providing a separate drain valve at the bottom of the drain provided at the bottom.

However, the above-mentioned prior art has the disadvantage of having a relatively complex structure and a high failure rate because the structure for separating condensate from compressed air uses a separator plate, and it also has the disadvantage of having a separate drain valve at the bottom of the drain, so the overall size is small. Because it is bulky, it is difficult to install in places with limited installation space.

And since the above-mentioned prior art is to supply compressed air with moisture removed as is to the place of use, the use of compressed air is accompanied by unsanitary problems in places such as food factories.

The present invention will be described in more detail based on the attached preferred embodiment drawings as follows.

Referring to FIG. 1, the present invention has a cylindrical water separation chamber 11 in the upper part of the body 10, and a water collection chamber 17 in communication with each other in the lower part of the water separation chamber 11. It is desirable to provide a partition piece 18 with a plurality of sap passing holes 18a between the moisture separation chamber 11 and the water collection chamber 17.

In some cases, the body 10 may be manufactured separately into a part of the body 10 containing the water separation chamber 11 and a part of the body 10 containing the water collection chamber 17 so that they are combined with each other.

Therefore, an air inlet 12 is provided on one upper side of the body 10, and a strainer 13 is built into the air inlet 12 to prevent foreign substances mixed in the compressed air flowing into the air inlet 12. It is configured to prevent foreign substances from entering the moisture separation chamber (11) by being caught on the filtering net (13).

In addition, the upper part of the moisture separation chamber (11) is provided with an air discharge pipe (14) for whirlpool generation that communicates with the air inlet (12), and the air discharge pipe (14) for whirlwind generation is inclined downward as shown in FIG. In order to discharge compressed air in the circumferential direction, the air discharge pipe 14 is bent in the circumferential direction so that the discharge port 14a contacts or is fixed to the inner peripheral surface of the body 10.

That is, the air discharge pipe 14 is configured to allow the discharge port 14a to approach or contact the inner peripheral surface of the body 10 inside the moisture separation chamber 11, and to allow the compressed air blown from the discharge port 14a to be blown in the circumferential direction. will be.

Therefore, the compressed air coming through the air inlet (12) is discharged from the moisture separation chamber (11) to the air discharge pipe (14) for whirlpool generation. At this time, the compressed air discharged from the air discharge pipe (14) for whirlpool generation is discharged from the lower part of the water separation chamber (11). As shown in FIG. 2, while facing the direction, it strikes the inner circumferential surface of the body 10 and is guided and rotated in the circumferential direction, thereby creating a whirlwind and blowing downward, thereby generating a centrifugal force and having a specific gravity higher than that of air. High moisture is moved by centrifugal force to the inner peripheral surface of the body 10 in the moisture separation chamber 11 and sticks thereto.

And the moisture (Wa) that sticks to the inner peripheral surface of the body (10) in the moisture separation chamber (11) condenses and flows downward, flowing into the water collection chamber (17) through the sap passage hole (18a).

Meanwhile, the upper central body 10 of the moisture separation chamber 11 is provided with an upper central exhaust hole 15 and is configured to communicate with the air exhaust port 15a on one side.

That is, an upper central exhaust hole 15 is provided at the top of the moisture separation chamber 11 to communicate with the air exhaust port 15a, and a sterilization filter 16 is placed between the upper central exhaust hole 15 and the air exhaust port 15a. ) is installed so that the compressed air discharged from the moisture separation chamber 11 is sterilized and discharged.

A sterilizing filter 16 is built inside the air exhaust port 15a. Air is sterilized as it passes through the sterilizing filter 16, and since it is already known, a detailed description of the detailed sterilizing ingredients and actions will be omitted.

Therefore, due to the centrifugal force of the whirlwind, the moisture mixed in the compressed air moves and sticks to the inner peripheral surface of the body (10) and flows into the water collection chamber (17). At the same time, the compressed air from which the moisture has been separated passes through the upper central exhaust hole (15). During the exhaust process, the sterilized compressed air passes through the sterilizing filter 16 and is exhausted through the air exhaust port 15a.

Referring to Figures 1 and 3, the water collection chamber 17 is configured in the shape of an inverted cone with a diameter that is wide at the top and narrows toward the bottom, and is configured to have an inverted conical inclined inner peripheral surface 171.

In addition, in the present invention, the float 20 is built into the water collection chamber 17 and can move in the vertical direction, and the body 10 is made of high-strength plastic so that the float 20 in the water collection chamber 17 can be visually identified. It is desirable to make it made of material.

The float 20 is preferably configured to have a buoyancy generating air chamber 21 therein and is fixed so that a sealing cap member 22 is covered on the top of the buoyancy generating air chamber 21, and the float 20 ) is preferably made of plastic material with a lower specific gravity than water.

In addition, the float 20 is entirely composed of an inverted cone shape with a diameter that is wide at the top and narrows toward the bottom, and on its outer peripheral surface, as shown in FIGS. 4 and 5, a plurality of protrusions are inclined downward and at equal intervals. It is configured to have a plurality of downwardly inclined ribs 23, and is configured to have each drop channel 24 between the plurality of downwardly inclined ribs 23. That is, downwardly inclined ribs 23 protrude parallel to the vertical direction of the inverted cone-shaped outer peripheral surface of the float 20.

And, as shown in FIG. 1, the inverted cone-shaped valve packing 25 provided at the lower center of the float 20 and the upper end of the drain nipple 31 on the body 10 are in contact with each other, and at the same time, the float 20 is in contact. In a state in which it is completely moved in the downward direction, the inverted cone-shaped inclined inner peripheral surface 171 of the water collection chamber 17 and the outer end of the downwardly inclined rib 23 of the float 20 are aligned. In addition, in the above state, the lower part of the float 20 is configured to form a liquid pooling space 172 in which the sap (W) accumulates.

The valve packing 25 is preferably made of silicone rubber, and as shown in FIG. 6, the valve packing 25 in an inverted cone shape is attached to the float ( 20) and is configured to be fixed.

Referring to FIG. 6, the packing holder 26 has an inverted cone-shaped mounting hole 27 in the center, and a valve packing 25 of the same shape as an inverted cone is built into the inverted cone-shaped mounting hole 27 to form a packing holder. (26) A portion of the inverted cone-shaped valve packing (25) is installed exposed to the lower part.

Therefore, the inverted cone-shaped valve packing 25 is also mounted on the inverted cone-shaped mounting hole 27 of the packing holder 26, so that all of them have an inverted cone shape in which the upper diameter is relatively wide and the lower diameter is relatively small. Since the valve packing 25 in the inverted cone shape does not come off in the lower direction of the packing holder 26, even if the float 20 moves in the up and down direction, the valve packing 25 in the inverted cone shape is separated from the float 20. The packing 25 will never come off. Therefore, malfunctions caused by separation of the inverted cone-shaped valve packing 25 can be prevented in advance, and product reliability can be greatly improved.

Additionally, the packing holder 26 may be screwed to the bottom of the float 20, or may be mounted in an interference fit manner. Therefore, since the packing holder 26 is detachable from the float 20, when the inverted cone-shaped valve packing 25 is worn or defective, the packing holder 26 can be separated and only the inverted cone-shaped valve packing 25 is used. It can be replaced.

Referring to Figure 3, in the present invention, the moisture (Wa) that sticks to the inner peripheral surface of the moisture separation chamber (11) of the body (10) is condensed to form sap and flows downward along the inner peripheral surface of the moisture separation chamber (11). As it flows down, it passes through the sap passage hole (18a), flows into the collection chamber (17), falls on the upper surface of the float (20), and spreads in all directions, forming the drop drain (24) on the outer peripheral surface of the float (20). It flows downward through .

The sap flowing down the drop drain 24 fills the liquid pooling space 172 and gradually fills the middle part of the upper drop drain 24, causing the float 20 to move. As shown in FIG. 8, by being moved upwardly, the inverted cone-shaped valve packing 25, which was shielding the vertical drain hole 32 of the drain nipple 31, is moved upward and the drain nipple 31 ), the vertical drain hole 32 is opened, and the sap (W) in the liquid stagnant space 172 is discharged into the vertical drain hole 32.

In the present invention, since both the water collection chamber 17 and the float 20 are configured in an inverted cone shape, they are not really noticeable to the naked eye, but when the float 20 is moved upward by buoyancy, the float 20 Since it can be tilted in one direction, the downwardly inclined rib 23 is also tilted as shown in (a) of FIG. 7, thereby creating a gap (K) or gap between the reverse conical inclined inner peripheral surface 171 and the downwardly inclined rib 23. This inevitably occurs, so that the vertical center line (S) of the vertical drain hole (32) and the inverted cone-shaped valve packing (25) are not aligned in a vertical state.

However, in the present invention, even if the gap K as described above occurs and the vertical center line S of the vertical drain hole 32 and the inverted cone-shaped valve packing 25 are not aligned in a vertical state, the float 20 is lowered. When moved, the downwardly inclined rib 23 contacts the inverted conical inclined inner peripheral surface 171 and gradually goes down, so that the float 20 is gradually erected in the vertical direction, and finally, as shown in (b) of Figure 7. As the downwardly inclined rib (23) is seated in a state of alignment with the inverted conical inclined inner peripheral surface (171), the vertical center line (S) of the vertical drain hole (32) and the inverted cone-shaped valve packing (25) are automatically aligned. The vertical drain hole 32 is shielded without malfunction.

And, as described above, the sap (W) gradually flows into the liquid pooling space (172), and the float (20) is moved upward by buoyancy, drained, and then moved back down to serve as a shield for the vertical drain hole (32). By operating repeatedly, the sap (W) is automatically drained at any time.

As shown in FIG. 1, at the lower center of the water collection chamber 17 of the body 10, there is an elongated drain nipple 31 with a vertical drain hole 32 in communication with the water collection chamber 17. It is fixed, and the cover member 40 is configured to cover the outside of the body 10 where the water collection chamber 17 is located so as to have a space 41 spaced apart from each other.

The cover member 40 is preferably made of a transparent plastic material. As shown in FIG. 1, the upper cover part 42 is coupled to the fitting groove 19 formed in the middle of the body 10, and the cover member 40 ) As shown in FIG. 6, the lower part has a spacer nut 44 and a compression nut fastened to the drain nipple 31 at the upper and lower parts of the lower central hole 43 of the cover member 40 through which the drain nipple 31 penetrates. It is configured to be firmly fixed by being fixed by (45).

Therefore, if an external force is applied due to carelessness, the external force is first applied to the cover member 40 to protect it, or only the cover member 40 is damaged and the body 10 is safely protected without being damaged.

In addition, for example, if the body 10 cannot withstand the internal pressure (compressed air pressure) and ruptures, the cover member 40 blocks the fragments from flying to the outside, thereby preventing injury to surrounding workers. do.

At this time, as shown in FIG. 1, high-pressure compressed air is discharged through the pressure fluid discharge hole 46 provided in the lower part of the cover member 40, thereby preventing damage to the cover member 40. , by allowing the pieces of the damaged body 10 to be collected within the cover member 40, safety from injury can be further secured.

The present invention is not necessarily limited to what is shown and described in the drawings, and may be modified and implemented in various ways by those skilled in the art to which the present invention pertains, so it should be broadly protected as long as it does not significantly depart from the scope of the claims. This is self-evident.
