Description

Oil leak-proof agitator equipped with a lubricant overflow prevention function {OIL LEAKAGE PREVENTION TYPE AGITATOR WITH LUBRICATING OIL OVERFLOW PREVENTION FUNCTION}

The present invention relates to a leak-proof stirrer equipped with a lubricant overflow prevention function. More specifically, it is installed in a place where water treatment is required, such as a water purification plant or sewage treatment plant, and is installed to agitate the mixed solution in the stirrer tank to prevent the overflow phenomenon of the lubricant. It is about a leak-proof stirrer that can prevent leakage.

Generally, a stirring tank is provided in a place where water treatment is required, such as a water purification plant or sewage treatment plant, and a stirrer is installed in the stirring tank to stir the mixed solution in the mixing tank.

A stirrer for stirring the mixed liquid in the stirring tank includes a driving means that provides driving force, a reducer that receives rotational force from the driving means and reduces the speed at a predetermined rate, and a rotational force that is decelerated and output from the reducer at a predetermined rate. It may include an impeller.

Meanwhile, in the case of the reducer, at least one oil seal is usually installed between the housing of the reducer and the shaft to maintain airtightness.

In more detail, an oil seal is installed between the housing and the shaft of the reducer to maintain airtightness between the housing and the shaft, thereby preventing the lubricating oil filled inside the housing from leaking through the gap between the housing and the shaft, thereby forming a stirring tank. Make sure the mixed liquid inside is not contaminated.

However, in the case of the above reducer, due to the nature of driving with numerous gears meshing with each other, vibration and noise are generated during driving, and the shaft that rotates the impeller is rotated eccentrically under the influence of vibration, causing a gap between the housing and the shaft. The problem is that the oil seal installed to maintain airtightness frequently breaks away, deforms, or breaks, causing the lubricating oil filled in the reducer to leak through the gap between the housing and the shaft, contaminating the mixed solution in the stirring tank. There is.

Therefore, recently, a 'leakage-proof multi-axis stirrer' as published in Republic of Korea Patent Publication No. 10-1620514 (registration date May 4, 2016) has been developed and is being used.

In the case of the reducer applied to the leak-proof multi-axis agitator, a leak-proof groove is formed in the second pinion gear of the second reduction means, a guard part is installed inside the housing to be penetrated by the first shaft, and at least the oil-leak prevention groove is provided. A blocking wall is installed on the guard part to partially insert and surround the outside of the first shaft, so that the lubricating oil filled inside the housing is blocked by the blocking wall and does not flow into the blocking wall, thereby allowing the lubricating oil to separate between the housing and the first shaft. This is to prevent leakage between shafts.

In the case of the second reduction means applied to the leak-proof multi-axis agitator as described above, the inside of the housing must be periodically filled with lubricant through the lubricant inlet provided at the top of the housing. The manager fills the inside of the housing with lubricant through the lubricant inlet. There is a problem that the lubricant level is not visible when put in, so an overflow phenomenon in which the lubricant flows beyond the upper part of the blocking wall and flows between the inside of the blocking wall and the first shaft frequently occurs.

Meanwhile, even if a water level inspection unit is provided in the housing and lubricant is filled inside the housing while checking the level of the lubricant through the water level inspection unit, due to the viscosity of the lubricant, feedback on the lubricant level is not immediately delivered to the manager through the water level inspection unit and the lubricant is Since the lubricant level can be accurately measured through the water level inspection unit only after a certain period of time has passed after filling, the problem is that when filling the lubricant, an overflow phenomenon in which the lubricant flows beyond the barrier wall and flows between the inside of the barrier wall and the first shaft occurs very frequently. There is.

In addition, even if the lubricating oil is filled inside the housing at a level lower than the upper part of the blocking wall, when the second reduction means is activated, the first and second pinion gears inside the housing rotate, causing waves in the lubricating oil and causing the lubricating oil to go beyond the blocking wall. There is a problem that an overflow phenomenon occurs frequently between the inside of the blocking wall and the first shaft.

Republic of Korea Patent Publication No. 10-1620514 (2016. 05. 04.)

The purpose of the present invention is to fundamentally prevent the phenomenon of lubricating oil overflowing beyond the blocking wall between the blocking wall and the second shaft when replenishing or operating the lubricating oil inside the second reducer housing, preventing contamination of the mixed solution in the stirring tank due to lubricating oil leakage. The aim is to provide a leak-proof stirrer that has a completely preventable lubricant overflow prevention function.

Another object of the present invention is to provide a leak-proof stirrer equipped with a lubricant overflow prevention function that can automatically notify a manager when an appropriate level of lubricant is replenished inside the second reducer housing.

The aim is to provide a leak-proof stirrer equipped with a lubricant overflow prevention function that can significantly extend the service life.

Other detailed purposes of the present invention will be clearly understood and understood by experts or researchers in this technical field through the detailed contents described below.

In order to achieve the above object, the present invention includes a first reducer that receives rotational force from a driving means and outputs rotational force reduced at a predetermined rate through a first shaft, and a first reducer that receives the rotational force of the first shaft from the first reducer and outputs the rotational force reduced at a predetermined rate to a predetermined rate. The rotational force decelerated in proportion is output through the second shaft, and the second shaft is capable of preventing the overflow phenomenon in which the lubricant inside the housing flows beyond the blocking wall into the gap between the housing where the oil seal is installed and the second shaft. A leak-proof stirrer is provided that has an overflow prevention function for lubricating oil, including a reducer and at least one impeller installed on the second shaft to rotate in conjunction with the second shaft to agitate the mixed liquid in the stirring tank.

For example, the second reducer includes a housing provided with a lubricating oil inlet through which lubricating oil can be injected, a second shaft partially inserted into the housing and rotatably supported, and at least one impeller installed to rotate in conjunction with it. and a first gear unit disposed inside the housing and rotated by receiving rotational force from the first shaft of the first reducer, and installed on the second shaft to be disposed inside the housing to receive rotational force from the first gear unit. A second gear unit that receives the transmission and rotates the second shaft by slowing it down at a predetermined rate and is provided with an oil leak prevention groove, and at least a portion of the housing is inserted into the oil leak prevention groove and surrounds the outside of the second shaft. When the level of the lubricating oil inside the housing and the blocking wall protruding from the housing exceeds a predetermined height, the lubricating oil is discharged to the outside of the housing, so that the lubricating oil inside the housing flows beyond the blocking wall into the gap between the housing where the oil seal is installed and the second shaft. It may include an overflow prevention unit to prevent entry.

For example, the overflow prevention unit includes at least one lubricant discharge hole formed in the housing to discharge lubricant to the outside of the housing when the level of lubricant inside the housing exceeds a predetermined level, and the housing through the lubricant discharge hole. It may include a lubricant storage unit that receives and stores lubricant that is discharged to the outside.

Here, the lubricant discharge hole is preferably formed in the housing so that the flow rate of the lubricant discharged into the lubricant storage unit through the lubricant oil discharge hole is greater than the flow rate of the lubricant injected into the housing through the lubricant oil inlet provided in the housing.

In addition, the overflow prevention unit opens the lubricant discharge hole at the top so that lubricant exceeding a predetermined height flows in before the lubricant level inside the housing reaches the upper end of the blocking wall and then is discharged into the lubricant storage unit through the lubricant discharge hole. It may further include a pocket portion provided on the inner surface of the housing to surround it in an open state.

For another example, the overflow prevention unit includes an auxiliary blocking wall portion that protrudes from the lower surface of the housing to surround the blocking wall portion at a predetermined distance from the blocking wall portion, and is filled inside the housing to extend beyond the auxiliary blocking wall portion. At least one lubricant discharge hole formed in the auxiliary blocking wall to discharge the lubricant that has flowed into the space formed between the blocking wall and the auxiliary blocking wall to the outside of the auxiliary blocking wall, and connected to the lubricating oil discharge hole through a drain penetrating the housing. It may include a lubricant storage unit that receives and stores the lubricant that is discharged to the outside of the auxiliary blocking wall through the lubricant discharge hole through a drain.

Here, the auxiliary blocking wall portion is preferably formed lower than the height of the blocking wall portion.

In addition, at least one lubricant discharge hole is formed in the housing so that the flow rate of lubricant discharged to the outside of the auxiliary blocking wall through the lubricant oil discharge hole is greater than the flow rate of lubricant injected into the housing through the lubricant oil inlet provided in the housing. It is desirable to be

Meanwhile, the overflow prevention unit may further include a notification means for detecting whether lubricating oil flows into the lubricating oil storage unit and notifying the manager of whether the lubricating oil is overflowing.

For example, the notification means includes a lubricant detection unit that detects lubricant flowing into the lubricant storage unit, a lighting unit disposed outside the lubricant storage unit, and a lubricant detection unit that detects that lubricant oil has flowed into the lubricant storage unit. It may include a control unit that operates the lighting unit.

For another example, the notification means is a lighting unit in which a negative power line is inserted and connected to one side of the lubricating oil storage unit and a positive power line is inserted and connected to the other side, and one of the positive power line and the negative power line of the lighting unit. Including a battery connected to the power line, the negative power line and the positive power line of the lighting unit are connected by the lubricant flowing into the lubricant storage unit, so that power to the lighting unit is applied from the battery, so that the lighting unit can be turned on. You can.

Here, the notification means is connected to the anode power line and the cathode power line of the lighting unit, and when lubricant flows into the lubricant storage unit, it is floated by the lubricant and connects the anode power line and the cathode power line to each other to apply power to the lighting unit from the battery. If possible, a switch that can turn on the lighting unit may be further included.

As described above, in the leak-proof stirrer equipped with the function of preventing overflow of lubricating oil according to an embodiment of the present invention, the manager injects lubricating oil into the housing of the second reducer through the lubricating oil inlet, so that the lubricating oil inside the housing reaches a predetermined level. If overfilled, the lubricant is discharged out of the housing through the lubricant discharge hole before the lubricant level reaches the upper end of the blocking wall, and is then transferred to the lubricant storage unit through the drain and stored.

Therefore, the leak-proof stirrer equipped with the function of preventing the overflow of lubricant according to an embodiment of the present invention does not fill the inside of the housing even if the manager fills the inside of the housing of the second reducer through the lubricant oil inlet to an appropriate level or more. The overflow phenomenon, in which lubricant flows beyond the blocking wall and flows between the blocking wall and the shaft, can be fundamentally blocked.

In addition, the leak-proof agitator, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, is inside the housing of the second reducer by sudden rotation of the first and second gear parts of the second reducer as in the initial operation. Even if a wave occurs in the lubricant filled in, the overflow phenomenon in which the lubricant flows beyond the barrier wall and flows between the barrier wall and the shaft can be fundamentally blocked.

Therefore, in the leak-proof stirrer, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, a phenomenon such as the second shaft being eccentrically rotated under the influence of vibration occurs, so that the blocking wall portion and the second shaft Even if the oil seal installed to maintain airtightness is separated, deformed, or damaged, the lubricant does not leak through the second shaft to the outside of the housing and contaminate the mixed solution in the stirring tank, so there is no lubricant leakage. It is effective in completely preventing contamination of the mixed solution in the stirring tank.

In addition, in the leak-proof stirrer, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, rainwater flows into the housing of the second reducer in the form of falling water through the air vent installed in the lubricating oil inlet due to rainy weather. Even if it flows in, rainwater floating on the lubricant is quickly discharged out of the housing through the lubricant discharge hole, which not only prevents the viscosity of the lubricant from changing, but also prevents corrosion of the internal parts of the housing, significantly extending its service life. There is a possible effect.

In addition, the leak-proof stirrer, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, discharges lubricating oil by replenishing the lubricating oil above a predetermined level when lubricating oil is replenished into the housing of the second reducer through the lubricating oil inlet. When the lubricant is discharged through the hole and stored in the lubricant storage unit, the lighting part of the notification means of the overflow prevention unit automatically turns on to inform the manager of the appropriate water level, which has the effect of improving the convenience of lubricant replenishment work.

Other effects of the present invention will be readily apparent and understood by experts or researchers in the technical field through the specific details described below or during the process of implementing the present invention.

1 to 11, the leak-proof stirrer 100, which can prevent the lubricant overflow phenomenon according to the present invention, includes a driving means 110, a first reducer 120, a second reducer 130, and , may include an impeller 140.

The driving means 110 may be installed to be separably coupled to the housing 121 of the first reducer 120, and a motor may be used as the driving means 110.

The first reducer 120 can receive rotational force from the driving means 110 installed to be separable and coupled to the housing 121, reduce the speed at a predetermined rate, and output it through the first shaft 122.

For example, the first reducer 120 can reduce the rotational force transmitted from the driving means 110 through a plurality of cycloid disks 123 at a predetermined rate and output it through the first shaft 122. A cycloidal reducer can be used.

The second reducer 130 receives rotational force from the first shaft 122 of the first reducer 120 and outputs the rotational force reduced at a predetermined rate through the second shaft 132, and is located inside the housing 131. It is possible to prevent an overflow phenomenon in which the lubricant flows beyond the blocking wall portion 135 into the gap between the housing 131 where the oil seal 131c is installed and the second shaft 132.

For example, the second reducer 130 includes a housing 131, a second shaft 132, a first gear unit 133, a second gear unit 134, a blocking wall unit 135, and an overflow prevention unit. It may include unit 136.

The housing 131 may be provided with a lubricant inlet 131a at the upper end through which lubricant can be injected.

Here, when the internal heat of the second reducer 130 is generated, air flows into the lubricant oil inlet 131a to cool it, so an air vent (not shown) is installed in the lubricant oil inlet 131a. It can be.

On the other hand, when the first and second gear parts 133 and 134 of the housing 131 are formed as spur gears as shown in FIG. 2, the reducer connection part 131b to which the first reducer 110 is connected is located at the top. It can be provided on the side.

Differently, the housing 131 has a reducer connection part 131b to which the first reducer 110 is connected when the first and second gear parts 133 and 134 are formed as bevel gears as shown in FIG. 5. It may be provided on the side.

The second shaft 132 may be partially inserted into the housing 131 and rotatably supported.

In more detail, the second shaft 132 may be rotatably supported by inserting its upper end into the housing 131 so that the lower part protrudes out of the housing 131.

The first gear unit 133 is disposed inside the housing 131, that is, inside the reducer connection part 131b of the housing 131, and is connected to the driving means 110. By being installed on the shaft 122, it can be rotated by receiving rotational force from the first reducer 120.

The second gear unit 134 is installed on the second shaft 132 to be disposed inside the housing 131, receives rotational force from the first gear unit 133, and decelerates the rotational force at a predetermined rate to rotate the second shaft 132. By rotating (132), a leakage prevention groove (134a) may be provided on the lower surface.

For example, the first gear unit 133 and the second gear unit 134, which receive rotational force from the first reducer 120 and reduce the speed at a predetermined rate to rotate the second shaft 132, are shown in FIG. 2. As described above, it can be formed as a spur gear.

For another example, the first gear unit 133 and the second gear unit 134, which receive rotational force from the first reducer 120 and reduce the speed at a predetermined rate to rotate the second shaft 132, are shown in Figure 5. As shown, it can be formed as a bevel gear.

The blocking wall portion 135 may be at least partially inserted into the oil leak prevention groove portion 134a and may be formed to protrude from the lower surface of the housing 131 to surround the outside of the second shaft 132.

The overflow prevention unit 136 discharges the lubricant to the outside of the housing 131 when the level of the lubricant inside the housing 131 exceeds a predetermined level, so that the lubricant inside the housing 131 exceeds the barrier wall 135 and becomes oil. This prevents the seal 131c from flowing into the gap between the housing 131 and the second shaft 132 where the seal 131c is installed.

For example, the overflow prevention unit 136 may include a lubricant oil discharge hole 136a and a lubricant storage unit 136b, as shown in FIGS. 1 to 6.

At least one lubricant discharge hole 136a may be formed in the housing 131 to discharge the lubricant to the outside of the housing 131 when the level of the lubricant filled inside the housing 131 exceeds a predetermined height.

Here, the lubricant discharge hole 136a allows the lubricant filled inside the housing 131 to exceed the blocking wall portion 135 and enter between the housing 131 where the oil seal 131c is installed and the second shaft 132. It is preferable that at least one is formed in the housing 131 to be located at a lower position than the upper end of the blocking wall portion 135 to prevent it from flowing into the gap.

In addition, the lubricant oil discharge hole 136a has a higher flow rate of lubricant injected into the housing 131 through the lubricant inlet 131a provided in the housing 131 than the lubricant oil storage unit 136b through the lubricant discharge hole 136a. ) It is preferable that at least one is formed in the housing 131 so that the flow rate of lubricating oil discharged to the tank is large.

The lubricating oil storage unit 136b is connected to the lubricating oil discharge hole 136a through a drain 136c and supplies lubricating oil discharged to the outside of the housing 131 through the lubricating oil discharge hole 136a through the drain 136c. You can receive and save it.

Additionally, the overflow prevention unit 136 may further include a pocket portion 136d.

As shown in FIG. 6, the pocket portion 136d has a lubricant discharge hole 136a after lubricant above a predetermined height flows in before the lubricant level inside the housing 110 rises to the upper end of the blocking wall portion 135. The inner surface of the housing 131 may be provided to surround the lubricant discharge hole 136a with an open top so that it can be discharged into the lubricant storage unit 136b.

For another example, the overflow prevention unit 136 may include an auxiliary blocking wall portion 136f, a lubricant discharge hole 136a, and a lubricant storage portion 136b, as shown in FIGS. 7 to 8. .

The auxiliary blocking wall portion 136f may be formed to protrude from the lower surface of the housing 131 to surround the blocking wall portion 135 while being spaced apart from the blocking wall portion 135 at a predetermined distance.

Here, the height of the auxiliary blocking wall portion 136f is such that the lubricant filled inside the housing 131 exceeds the blocking wall portion 135 and falls between the housing 131 and the shaft 132 where the oil seal 131c is installed. It is preferable that it is formed lower than the height of the blocking wall portion 135 to prevent it from flowing into the gap.

The lubricant discharge hole 136a discharges the lubricant filled inside the housing 131 and flowing into the space S formed between the auxiliary barrier wall portion 131f and the barrier wall portion 135 to the auxiliary barrier wall portion ( 136f) At least one may be formed in the auxiliary blocking wall portion 136f to allow discharge to the outside.

Here, the lubricating oil discharge hole 136a can immediately discharge the lubricating oil that has flowed beyond the auxiliary blocking wall part 136f into the space S formed between the blocking wall part 135 and out of the auxiliary blocking wall part 136f. It is preferable that it is formed at the lower end of the auxiliary blocking wall portion 136f.

In addition, the lubricant discharge hole 136a has a flow rate of lubricant injected into the housing 110 through the lubricant inlet 111 provided in the housing 131. The auxiliary blocking wall portion 136f passes through the lubricant discharge hole 131a. ) It is preferable that at least one is formed in the housing 131 so that the flow rate of lubricating oil discharged to the outside is large.

The lubricant storage unit 136b is connected to the lubricant discharge hole 136a through a drain 136c penetrating the housing 131 and discharges the lubricant oil to the outside of the auxiliary blocking wall portion 136f through the lubricant discharge hole 136a. Lubricating oil can be supplied and stored through the drain 136c.

Additionally, the overflow prevention unit 136 may further include a notification means 136e.

The notification means (136e) detects whether lubricant oil flows into the lubricant oil storage unit (136b) and informs the manager whether the lubricant overflows.

For example, the notification means 136e may include a lubricant detection unit 1361e, a lighting unit 1362e, and a control unit 1363e, as shown in FIG. 9 .

The lubricant detection unit 1361e is capable of detecting lubricant oil flowing into the lubricant storage unit 136b.

The lighting unit 1362e may be disposed outside the lubricant storage unit 136b.

The control unit 1363e operates the lighting unit 1362e when the lubricant detection unit 1361e detects that lubricant has flowed into the lubricant storage unit 136b.

Here, it is desirable to use LED as the lighting unit 1362e.

For another example, the notification means 136e may include a lighting unit 1364e and a battery 1365e as shown in FIG. 10.

The lighting unit 1364e may be connected by inserting a negative power line (L1) into one side of the lubricant storage unit (136b) and by inserting a positive power line (L2) into the other side of the lubricant storage unit (136b).

For example, it is desirable to use LED as the lighting unit 1364e.

The battery 1365e may be connected to either the negative power line L1 or the positive power line L2 of the lighting unit 1364e.

Therefore, when the lubricating oil 137 flows into the lubricating oil storage unit 136b, the positive power line L2 and the negative power line L1 of the lighting unit 1364e are connected by the lubricating oil 137 flowing into the lubricating oil storage unit 136b. ) are connected to each other, so that power is applied from the battery 1365e to the lighting unit 1364e, so that the lighting unit 1364e can be turned on.

In addition, the notification means 136e may further include a switch 1366e connected to the anode power line L2 and the cathode power line L1 of the lighting unit 1364e, as shown in FIG. 11.

When the lubricating oil 137 flows into the lubricating oil storage unit 136b, the switch 1366e is floated by the lubricating oil 137 flowing into the lubricating oil storage unit 136b and is connected to the positive power line L2 of the lighting unit 1364e. By connecting the cathode power lines (L1) to each other, power is supplied from the battery 1365e to the lighting unit 1364e so that the lighting unit 1364e can be turned on.

Again, referring to FIGS. 1 to 11, the operation process and effects of the leak-proof stirrer that can prevent the overflow of lubricating oil according to the present invention will be described.

Referring to FIGS. 1 to 11, in the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to the present invention, the rotational force is transferred to the first reducer 120 as the driving means 110 is operated. When transmitted, the rotational force transmitted from the driving means 110 is decelerated at a predetermined rate through the cycloid disk 123 of the first reducer 120 and then output through the first shaft 122.

The rotational force output through the first shaft 122 rotates the first gear unit 133 of the second reducer 130.

Meanwhile, the second gear unit 134, which is gear-connected to the first gear unit 133, receives rotational force from the first gear unit 133 and rotates at a reduced speed at a predetermined rate, and the second gear unit ( The rotational force reduced at a predetermined rate by 134) is output through the second shaft 132 of the second reducer 130.

When the second shaft 132 of the second reducer 130 rotates, at least one impeller 140 installed on the second shaft 132 rotates in conjunction with the second shaft 132, thereby forming a stirring tank. The mixed liquid inside is stirred.

When the second reducer 130 applied to the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, is used for more than a predetermined time, the first and second gear units ( In order to reduce the mechanical friction of 133)(134) or to disperse frictional heat generated from the friction surface, the amount of lubricant filled inside the housing 131 is reduced.

When the amount of lubricant filled inside the housing 131 is reduced below a predetermined level, the friction force generated as the first and second gear parts 133 and 134 operate increases, and at the same time, the first and second gear parts ( As 133)(134) operates, frictional heat generated is not properly distributed, resulting in excessive heat being generated inside the housing 131.

Therefore, when the lubricant filled inside the housing 131 decreases below the predetermined level, the manager injects the lubricant into the housing 131 through the lubricant inlet 131a provided in the housing 131 to periodically lubricate the housing 131 to the predetermined level. Only by filling can the frictional force generated as the first and second gear parts 133 and 134 operate be reduced and the frictional heat can be properly distributed.

However, in the case of a reducer applied to a conventional agitator, when the operator fills the lubricant into the housing through the lubricant inlet, the lubricant level is not visible, so the lubricant flows beyond the upper part of the blocking wall and flows between the blocking wall and the shaft. Overflow phenomenon occurs frequently.

Meanwhile, even if a water level inspection unit is provided in the housing and lubricant is filled inside the housing while checking the level of the lubricant through the water level inspection unit, due to the viscosity of the lubricant, feedback on the lubricant level is not immediately delivered to the manager through the water level inspection unit and the lubricant must be filled. Since the lubricant level can be accurately checked through the water level inspection unit only after a certain period of time has passed after insertion, an overflow phenomenon in which lubricant flows beyond the blocking wall and flows between the blocking wall and the shaft frequently occurs.

The lubricating oil that flows beyond the barrier wall and between the barrier wall and the shaft causes the shaft to rotate eccentrically under the influence of vibration, causing the oil seal installed to maintain airtightness between the barrier wall and the shaft to be separated or deformed. If damage occurs, there is a fatal problem in that it leaks down the shaft and out of the housing, contaminating the mixed solution in the stirring tank.

On the other hand, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention as shown in FIGS. 1 to 6, allows the manager to use the second lubricant inlet 131a through the lubricating oil inlet 131a. When lubricant is injected into the housing 131 of the reducer 130 and the lubricant is filled above a predetermined level, the lubricant is discharged through the lubricant discharge hole 136a before the lubricant level reaches the upper end of the blocking wall 135. ) is discharged to the outside of the housing 131 and then transferred to the lubricant storage unit 136b through the drain 136c and stored.

Meanwhile, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to another embodiment of the present invention as shown in FIGS. 7 and 8, allows the manager to insert the housing 131 through the lubricating oil inlet 131a. When lubricant is injected into the housing 131 to fill the inside of the housing 131 above a predetermined level and the lubricant flows beyond the auxiliary blocking wall portion 136f into the space S formed between the blocking wall portion 135, the lubricating oil discharge hole ( After being discharged to the outside of the housing 131 through 136a) and drain 136c, it is transferred to the lubricant storage unit 136b and stored.

Therefore, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, is installed inside the housing 131 of the second reducer 130 through the lubricating oil inlet 131a. Even if the lubricant is filled to an appropriate level or higher, the overflow phenomenon in which the lubricant filled inside the housing 131 flows beyond the barrier wall 135 and flows between the barrier wall 135 and the second shaft 132 can be fundamentally prevented.

In addition, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, includes the first and second gear units 133 of the second reducer 130 as in the initial operation. Even if a wave is generated in the lubricant oil filled inside the housing 131 of the second reducer 130 due to the sudden rotation of 134), the lubricant exceeds the barrier wall portion 135 and is transmitted to the barrier wall portion 135 and the second shaft 132. ) can fundamentally block the overflow phenomenon that flows through the space.

Accordingly, in the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, a phenomenon such as the second shaft 132 being rotated eccentrically under the influence of vibration occurs. Even if the oil seal 131c installed to maintain airtightness between the blocking wall 135 and the second shaft 132 is separated, deformed, or damaged, the lubricant travels through the second shaft 132 and into the housing ( 131) It has the advantage that it does not leak to the outside and contaminate the mixed solution in the stirring tank.

Meanwhile, in the case of a general reducer applied to a stirrer, external air must generally flow into the housing for cooling when internal heat is generated, so an air vent is installed at the lubricant inlet.

Not only outside air flows into the housing through the air vent installed in the lubricant inlet, but also rainwater during rainy weather flows into the housing through the air vent in the form of falling water, and rainwater flows into the housing and floats on the lubricant. There is a problem in that it not only changes the viscosity of the lubricant but also corrodes the internal parts of the housing by preventing it from being discharged outside the housing.

On the other hand, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, is operated through an air vent (not shown) installed in the lubricating oil inlet 131a due to rainy weather. Even if rainwater flows into the housing 131 of the second reducer 130 in the form of falling water, the rainwater floating on the lubricant is quickly discharged to the outside of the housing 131 through the lubricant discharge hole 136a, thereby reducing the viscosity of the lubricant. Not only can it prevent changes, but it can also prevent corrosion of the internal parts of the housing 131, thereby significantly improving the product's service life.

In addition, the leak-proof stirrer 100, which can prevent the overflow phenomenon of lubricating oil according to an embodiment of the present invention, pumps lubricating oil into the housing 131 of the second reducer 130 through the lubricating oil inlet 131a. When replenishing, when the lubricant is replenished above a predetermined level and the lubricant is discharged through the lubricant discharge hole 136a and stored in the lubricant storage unit 136b, the lighting unit 1362e of the notification means 136e of the overflow prevention unit 136 ( 1364e) lights up automatically to inform the manager of the appropriate water level, thereby improving the convenience of lubricant replenishment work.
