Description

Liquid Auto Drainer

The present invention relates to an automatic liquid discharge device, and more particularly, to an improved automatic liquid discharge device to ensure a float operation for automatically discharging liquid.

As a prior art document, an automatic liquid discharge device such as Korean Patent No. 10-1824456 is disclosed as a prior art.

However, in the above prior art, the float must be made of a material having a specific gravity lower than the liquid in order to move the float upward. In the case of a material having a specific gravity lower than the liquid, the manufacturing cost is very high, leading to an increase in manufacturing cost, thereby weakening the competitiveness. It is accompanied by a problem that results.

In addition, the above-described prior art has a problem in that the liquid falling from the liquid inlet is dispersed in all directions and dropped into the float, causing the float to swing greatly from side to side, thereby limiting its use.

It is an object of the present invention to provide a liquid automatic discharge device which can be operated at all irrespective of the specific gravity of a float and can be used for general purpose and can be used for general purpose.

Another object of the present invention is to provide a good automatic liquid discharge by allowing buoyancy to be increased as much as possible even if the float is composed of a material having a high specific gravity.

Still another object of the present invention is to improve the competitiveness of the product by improving the performance of the product while improving the production cost while improving the automatic liquid discharge.

The present invention is a collection chamber having a liquid inlet, an inverted inclined inner circumferential surface formed to have an inner diameter wider at the lower portion of the straight inner circumferential surface and narrower toward the lower portion, a drain body having a drain hole at the center of the lower portion of the collection chamber, and in the collection chamber. A float having a built-in flow and having an external communication air chamber, an inverse conical inclined portion formed in the same shape as the inverse conical inclined inner circumferential surface below the upright portion of the float, and an inverse conical inclined inner circumferential surface on the outer circumferential surface of the inverted conical inclined portion A plurality of downward slope ribs protruding obliquely in a downward direction, a plurality of drainage paths provided between the plurality of downward slope ribs, and a buoyancy force protruding from the inverted conical inclined portion in the center of the opening and closing wheel wheel portion is formed in the bottom of the float Characterized in that it is configured to include a generating space portion.

One or more pressure balance vents communicated with the external communication air chamber at the upper portion of the float, or the water blocking outer wall having an air vent communicated with the pressure balance vents at the bottom of the pressure balance vent and the lower portion of the pressure balance vents. It is another feature that is made.

The upper surface of the float is characterized in that it is configured to be further provided with a concentrated pressure action groove formed in a concave shape inclined toward the center from the upper surface edge portion.

The present invention has an effect that the buoyancy is increased as much as possible even if the float is composed of a material having a high specific gravity to provide a liquid automatic discharge device that is well operated.

In addition, even if a high internal pressure is generated inside the collection chamber in the liquid inflow state, air does not enter the float, so the float is not crushed, so the liquid is automatically discharged well without being affected by the fluid pressure flowing into the collection chamber. It is effective to provide a liquid automatic discharge device that can be used as.

In addition, the present invention has the effect that it is possible to reduce the float manufacturing cost while the automatic liquid discharge is good, so that it is possible to disseminate products with improved performance at a lower cost, thereby providing a significant improvement in competitiveness.

The present invention is a liquid inlet 111, a collecting chamber 120 having an inverted conical inclined inner circumferential surface 122 formed to have an inner diameter that is wider at the lower side and narrower toward the lower side, and in the lower center of the collecting chamber 120 The drain body 100 having a drain hole 130 and

The reverse conical inclined portion 221 and the inverted cone-shaped inclined portion 221 formed on the outer circumferential surface of the reverse conical inclined portion 221 and the reverse conical inclined portion 221 formed in the same shape as the reverse conical inclined inner circumferential surface 122. A plurality of downward slope ribs 230 protruding obliquely downward to be matched with the plurality of downward slope ribs, a plurality of drainage passages 231 provided between the plurality of downward slope ribs 230, and the reverse conical slope portion. The opening and closing wheel part 240 protrudes in the lower center thereof, and includes a float 200, and external communication air provided inside the float 200 through the pressure balance vent hole 211 in the upper portion of the float 200. In order to allow the air to enter and exit the seal 210, a liquid automatic discharge device has been developed to have a buoyancy generating space 250 below the float 200.

When described in more detail on the basis of the accompanying drawings the preferred embodiment of the present invention.

Referring to Figures 1 to 3, the present invention is largely divided into a drain body 100 having a collecting chamber 120 through which the liquid is introduced through the liquid inlet 111, and is built up in the collecting chamber 120 up and down It is comprised by the float 200 moved to a direction.

Therefore, the collection chamber 120 of the drain body 100 is configured to have an inverted conical inclined inner peripheral surface 122 having an inner diameter wider at the lower portion of the straight inner circumferential surface 121 configured as the upper portion and narrowing toward the lower portion. The center of the lower portion of the collecting chamber 120 is configured to have a drain hole 130.

It is preferable to be fastened to the upper cap 110 having the liquid inlet 111 in the upper part of the collecting chamber 120, and the symbol Pa denotes an inlet pipe connected to the liquid inlet 111.

The drain hole 130 provided at the bottom of the collecting chamber 120 may be provided at the drain nipple 132 so that the drain nipple 132 may be fastened to the drain main body 100 at the lower side of the collecting chamber 120. In some cases, the drain nipple 132 may be excluded and the drain body 130 may be formed in the drain body 100 itself, and the protrusion 131 may protrude from the upper part of the drain hole 130. will be. Reference numeral Pb denotes a drain pipe connected to the drain hole 130.

The float 200 is configured to have an external communication air chamber 210 therein.

The external communication air chamber 210 is configured to be provided with one or more pressure balance ventilation holes 211 communicated with the external communication air chamber 210 on the upper side.

The external communication air chamber 210 is provided so that the weight of the float 200 may be reduced so that the float 200 floats well on the water, but in this case, the thickness of the outer circumferential surface wall of the float 200 becomes thin. 200) Since the outer wall of the thin thickness of the float 200 may be distorted due to the difference in air pressure inside and outside, the present invention communicates with the external communication air chamber 210 on the upper side of the float 200. As one or more pressure balance ventilation holes 211 are provided, the air pressure inside and outside the float 200 is always the same, so that the float 200 is not distorted. The thickness of the float 200 may be configured to have a thin thickness, and as a result, the float 200 becomes lighter and floats well on water. Manufacturing costs can be reduced due to material savings.

That is, in the present invention, it is preferable to lighten the weight of the float 200 as much as possible in order to allow the float 200 to be moved well above the water by buoyancy. In this case, the float 200 is crushed by external pressure. It is to be so as not to be deformed or deformed is to be provided with at least one pressure balance vent hole 211 in communication with the external communication air chamber (210).

In order to facilitate understanding of the present invention, the liquid automatic discharge device such as the present invention is an automatic liquid discharge device for automatically discharging the separated liquid contained in the compressed air in the pneumatic system using the compressed air using an air compressor It can be mainly used as.

In this case, the compressed air is introduced together with the liquid through the liquid inlet 111 so that the air pressure of the collecting chamber 120 becomes a relatively higher air pressure than the external communication air chamber 210 of the float 200. 200 may be compressed and crushed.

Therefore, in the present invention, the air in the collection chamber 120 and the air in the external communication air chamber 210 enter each other through the pressure balance vent hole 211 of the float 200 so that the air pressures of both sides become equal to each other. By doing so, since the float 200 is not compressed and distorted, it is possible to faithfully perform the function of the float 200.

When the pressure balancing vent 211 is provided as described above, the water blocking outer wall 212 having the upper portion of the pressure balancing vent 211 outside is blocked and a vent 213 communicating with the pressure balancing vent 211 at the bottom thereof. ) Is further provided, it is preferable to block the upper portion of the vent 213 is blocked by the upper shielding portion 262 protruding to the edge of the air chamber cover member 260.

Therefore, the liquid falling down to the float 200 flows into the drainage passage 232 is not only blocked by the water blocking outer wall 212 and does not enter the pressure balance vent hole 211, but also the pressure balance vent hole Since the air vent 213 communicating with the 211 is provided toward the lower side of the water blocking outer wall 212, the liquid flowing down the water blocking outer wall 212 is never introduced into the pressure balancing vent 211.

Therefore, since the inhalation of water in the external communication air chamber 210 is prevented in advance, the present invention does not cause any buoyancy decay that may occur when water is sucked into the external communication air chamber 210. Float 200 will be able to faithfully perform the function.

1 and 2, the upper surface portion of the air chamber cover member 260 is provided with a concentrated pressure action groove 261 formed in a concave shape inclined toward the center from the edge as shown in FIGS. 1 and 2. It is composed.

The air chamber cover member 260 is provided to be fixed to the float 200 in the upper side of the external communication air chamber 210, for example, may be attached or fixed by a strong adhesive, or may be fixed using other fixing means. have.

However, since the present invention is to have an external communication air chamber 210, for example, without having a separate air chamber cover member 260, the air chamber cover member 260 and the upright part 2200 are integrally formed and It may be configured to be provided with a concentrated pressure action groove 261 on the side.

On the other hand, the float 100 having an external communication air chamber 210 has an upright portion 220 toward the upper side and a reverse conical slope having the same shape as the reverse conical inclined inner circumferential surface 122 below the upright portion 220. It is configured to have a portion 221.

In addition, the outer conical inclined portion 221 has a plurality of downward inclined ribs protruding obliquely downward in order to be matched with the inverted conical inclined inner circumferential surface 122, the plurality of downwards The inclined ribs 230 are configured to have respective drainage passages 231.

As shown in FIG. 2, the plurality of downhill ribs 230 may be provided with the straight ribs 230a extending in the upright part 220.

3 and 4, the straight ribs 230a preferably have the outer end portion in contact with the straight inner circumferential surface 121 so that the upright portion 220 of the float 200 can move in the vertical direction. In this case, it is preferable that the outer end of the straight rib 230a is rounded so that a good movement is achieved as the straight rib 230a and the straight inner circumferential surface 121 are moved in line contact state.

The opening and closing wheel part 240 protrudes in the lower center of the reverse conical inclined portion 221 so that the buoyancy generating space 250 is formed in the lower portion of the float 200.

The opening and closing wheel part 240 is provided with a recessed groove 241 which is opened to the lower side, and the packing 242 is inserted into the recess 242, so that the recess 242 inside the recess 242 in FIG. As shown, it is preferable to insert the protrusion part 131 having the drain hole 130 so that the drain hole 130 can be more surely closed as the drain hole 130 is in close contact with the packing 242.

In the present invention, the liquid flows into the collecting chamber 120 through the liquid inlet 111 and falls to the upper surface of the float 200. At this time, when the liquid falls linearly as shown by the arrow in FIG. It falls to 261 and is spread | emitted in all directions, and it flows down through the drainage path 231 in the outer peripheral surface of the float 200.

At this time, since the concentrated pressure action groove 261 is formed in a concave shape inclined toward the center from the edge of the upper surface of the air chamber cover member 260, the liquid is naturally gathered to the center of the concentrated pressure action groove 261. As the liquid load is loaded in the center of the concentrated central groove 261, the upper center portion of the float 200 is in a state in which the liquid load is more concentrated than the upper outer peripheral portion.

Therefore, since the center portion of the float 200 receives the concentrated liquid load, the center portion of the float 200 receives more concentrated pressure, so that the opening and closing wheel 240 in the lower center has a higher pressure to drain the drain hole 130. It will be able to shield.

That is, in the present invention, the pressure of the opening and closing wheel part 240 to shield the drain hole 130 is not limited to being pressed by the own load of the float 200, and not only the own load of the float 200 but also the center portion of the float 200. As the more concentrated pressure is received, the opening and closing wheel part 240 in the center of the lower side can shield the drain hole 130 at a higher pressure, so that the more reliable drain hole 130 is shielded.

Referring to FIG. 1, the liquid flowing down the drainage passage 231 is filled in the buoyancy generating space 250 and gradually rises to the drainage passage 231 at the upper side, which is shown as a virtual line in FIG. 1. When the liquid rises up to the water level line (W), the float 200 floats upward due to buoyancy and is moved. The above water level line (W) is only shown to help the understanding of the present invention and is not present in the actual product.

Therefore, when the float 200 floats upward, the opening / closing protrusion 240 moves upward and falls from the protrusion 131, so that the liquid in the buoyancy generating space 250 is opened as the drain hole 130 is opened. Is discharged to the drain hole (130).

Therefore, while the liquid is discharged to the drain hole 130, the float 200 is gradually lowered, wherein the present invention is a straight line in the upright portion 220 of the float 200 as shown in Figs. Since the outer end portion of the rib 230a and the straight inner circumferential surface 121 are in contact with each other, the float 200 is not tilted to one side even when the float 200 is moved up, and is moved up or down in a straight state. In addition to being in a state, as the float 200 moves downward, as shown in (b) of FIG. 5, the downward slope rib 230 automatically matches with the inverse conical inclined inner circumferential surface 122, so that the state is matched. The end portion of the opening and closing wheel part 240 is in a state where the vertical center line (S) of the drain hole 130 is in a state where the drain hole 130 is shielded.

Therefore, when the drain hole 130 is shielded as described above, the liquid coming down the drain passage 231 is filled in the buoyancy generating space 250 again, and the liquid is again shown in FIG. 1. When the water level line (W) is filled up, the float 200 is moved again by buoyancy, so that the drain hole 130 blocked by the opening and closing wheel part 240 is opened again, and the liquid is drained back to the drain pipe Pb. By repeating the action, the liquid is discharged automatically from time to time.

Therefore, since the float 200 is operated to move up by the buoyancy to open the drain hole 130, the present invention employs a material having a relatively high specific gravity in employing the float 200. It is not necessary to manufacture and employ the float 200, and because it is possible to employ a float 200 of a material having a relatively high proportion of material having a relatively low material price, and thus good regardless of the specific gravity of the float 20. It is to provide an automatic liquid discharge device that is operated.

In order to facilitate the understanding of the present invention, conventionally, the liquid discharged only when a float having a specific gravity lower than that of water was used. However, the present invention, since the buoyancy is increased, even when a float 200 having a specific gravity higher than water is employed, automatic discharge of liquid is achieved. In addition, the float having a lower specific gravity than water has a relatively high material purchase cost, while the float 200 having a higher specific gravity than water has a relatively low material purchase cost, thereby reducing manufacturing costs. This improved automatic liquid dispensing device becomes very inexpensive.

Therefore, the present invention preferably float 200 has a specific gravity higher than the water, but it is preferable to make the specific gravity as low as possible and to increase the buoyancy as possible to ensure good operation.

In the present invention, the liquid is naturally collected in the concentrated pressure acting groove 261, so that the central portion of the float 200 receives more concentrated pressure, so that the opening and closing wheel part 240 in the lower center has a stronger pressure. In order to shield the drain hole 130, the liquid flowing into the liquid inlet 111 is dispersed and introduced or may be implemented and employed regardless of being introduced in a straight state.

In addition, even if the internal pressure of the collection chamber 120 is high, since the float 200 does not distort and performs its role, it is not affected by the liquid inflow pressure at all, and the liquid is automatically discharged well. It will provide an automatic liquid discharge device.

Meanwhile, the present invention is implemented such that the outer end portion of the straight rib 230a in the upright portion 220 of the float 200 and the straight inner circumferential surface 121 are in contact with each other as shown in FIGS. 3 and 4. Preferably, however, in some cases, the inner diameter of the straight inner circumferential surface 121 may be larger than the diameter of the float 200 so that the outer end portion of the straight rib 230a may not be in contact with the straight inner circumferential surface 121. .

In this case, when the float 200 is moved up by the buoyancy, the float 200 may be inclined in one direction, and thus, the float 200 may be provided on the reverse conical inclined portion 221 and its outer circumferential surface. Since the downward inclination rib 230 is also inclined, a clearance K or a gap is inevitably generated between the inverted conical inclined inner circumferential surface 122 and the downward inclination rib 230 to open and close the vertical center line S of the drain hole 130. The wheel wheels 240 are in a state where they are not aligned in a vertical state.

However, in the present invention, if the clearance (K) is generated as described above, even if the vertical center line (S) of the drain hole 130 and the opening and closing wheel part 240 do not coincide in a vertical state, the float 200 is moved downwardly. As the downwardly inclined rib 230 contacts the inclined inner circumferential surface 122, the downwardly inclined rib 230 gradually descends, and as a result, the float 200 is gradually erected in the vertical direction, and finally, as shown in FIG. As the rib 230 is seated in a state in which it is fitted to the inverse conical inclined inner circumferential surface 122, the vertical center line S of the drain hole 130 and the opening and closing wheel part 240 are automatically matched to shield the drain hole 130. will be.

Therefore, the present invention is not necessarily limited to those illustrated and described in the drawings, and may be variously modified by those skilled in the art to which the present invention pertains, and therefore, the present invention should be broadly protected without departing from the scope of the claims. It is self-evident.

The present invention has the effect of improving the performance so that the correct operation is performed without error operation in the liquid discharge is made automatically.

In addition, as the float weight is reduced, it is possible to reduce the cost of material savings, thereby enabling the supply of high-performance products at a lower cost, thereby securing a high competitiveness both internally and externally. It can be used as a liquid automatic discharge device that removes moisture from the compressed air passing through the pneumatic pipe and automatically discharges it in the automated pneumatic production facility that uses compressed air to produce food or various products. Advanced liquid automatic ejectors have been introduced.
