[Industrial applications]

 The present invention relates to a sludge scraping plate drive device for an oil purifier, and in particular, a motor drives a sludge scraping plate and a cleaning tank to which sludge adheres at different speeds to easily and energy-savingly clean the sludge inside the cleaning tank. The present invention relates to a sludge scraping plate driving device in a possible oil purifier.

[0002]

[Prior art]

 Generally, factories that use large amounts of oil as a lubricant or coolant, such as those that produce bolts and nuts by high-speed forging, install a purifier to filter impurities and dirt from the used oil, Recycled clean oil is used again to reduce production costs and prevent circulation pollution.

As a conventional technique of a scraping plate drive device in an oil cleaner, there is an oil cleaner shown in FIG. 5. As shown in the figure, the oil cleaner of the conventional example is roughly classified into a body frame. 100, an oil cleaning means 3 provided so as to be transmitted and rotated with the shaft parallel to the power transmitting means 1, and a sludge generated in the oil cleaning means 3 when removing sludge. It is provided with a braking means 2 for temporarily stopping a part of the oil cleaning means 3.

The transmission means 1 integrally rotates a motor M attached to the machine body frame 100, an output pulley 11 of the motor M, and a rotary spindle 13 having a central hole axially mounted on the machine body frame 100. A rotation transmission mechanism is formed with the driven pulley 12, and the rotation main shaft 13 is inserted through one end to the other end of its center hole and manually rotated so as to be rotatable relative to the rotation main shaft 13 but not axially movable. The shaft 14 is inserted and pivotally supported, and the interlocking seat 15 is keyed so as to interlock with the shaft 14. The interlocking seat 15 is radially connected from the upper end of the cylindrical hub portion 15a connected to the rotary main shaft 13. A flange 150 protruding in a circular shape is provided, the cup-shaped cleaning tank 17 is covered by the flange 150 from the upper opening, and both can be interlocked with each other at the circumferential portion by a bolt 162. An overflow hole 151 that is integrally connected to the above and further communicates at least one of the inside and the outside upward.

Inside the cleaning tank 17, at the exposed tip of the lower end of the hand-turning shaft 14, two radiating members 31 extending in the diametrical direction of the oil cleaning means 3 can be rotated as a whole by a nut 141. A scraping plate 32 for scraping sludge is attached like a vane plate which is screwed and circularly moves along the inner peripheral surface of the oil cleaning tank 17 by the rotation of each radiation 31. The lower end of the plate 32 is also fixedly held at both ends of the plate and the shape retaining plate 34 through the two overhanging frames 33, and at the same time, an insertion hole 341 is opened in the center of the retaining plate 34 in order to ensure stability. The oil cleaning means 3 is formed by loosely inserting the rim portion of the return oil introducing pipe 35 which projects upward from the axial center position of the bottom of the cleaning tank 17 and opens so as not to shake during the circular movement.

Further, an oil storage tank R is formed on the machine frame 100 so as to surround the rotating cleaning tank 17 so that its upper portion is substantially covered and faces the flange portion 150 of the interlocking seat 15. The inner peripheral portion is provided with a slit to allow the regenerated oil to flow from the overflow hole 151, and at the same time, an outlet port R1 for flowing out and reusing the regenerated oil is also provided to the peripheral wall portion near the bottom surface. .

On the other hand, the braking means 2 is provided with a washer 16 in which a recessed retaining seat 161 is formed by a bolt 152 at a position near the peripheral edge of the flange portion 150 of the interlocking seat 15, and the retaining seat A holding cylinder 21 holding a lock pin 23 at its lower end to be movable back and forth with respect to the stop seat 161 is attached to the machine body frame 100 at a position facing the circular motion trajectory of 161 and is normally retracted by a coil spring 22. When the locking seat 161 is urged to move and is positioned immediately below, if the rear end portion 231 of the lock pin 23 is pushed downward to extend, the tip end of the locking pin 23 protrudes into the locking seat 161 and becomes continuous. The moving seat 15 is pressed to brake the clean tank 17 so as not to rotate.

When cleaning oil with the oil cleaner configured as described above, first, the lock pin 23 is retracted upward by the bias of the spring 22, and the lower end of the lock pin 23 and the washer 16 When a proper distance is maintained between the stopper seat 161 and the motor M, and the motor M is started and rotated, the rotation main shaft 13 is rotated by the transmission of the belt, and at the same time, the interlocking seat 15 and the cleaning tank 17 are interlocked. And rotate them together.

That is, the recovered oil sucked by the pump or the like is injected into the clean tank 17 through the return oil introducing pipe 35 and enters the clean tank 17, and the centrifugal force acts as the clean tank 17 rotates. The sludge containing the adhering sludge adheres to and remains on the inner wall of the clean tank 17, and the clean regenerated oil from which suspended impurities are separated is discharged from the overflow hole 151 of the interlocking seat 15 and concentrated in the stop tank R. When it becomes an appropriate amount, it flows out from the clean oil outlet R1 and is used for circulation reuse.

On the other hand, when removing the sludge adhering to the cleaning tank 17 of the oil purifier, first, as shown in FIG. 6, the lock pin 23 of the contact stopping means 2 is pushed down to stop the washer. When abutting and restraining the contact with the inside of 161, members such as the washer 16, the interlocking seat 15 and the rotary main shaft 13 are fixedly restrained, and the clean tank 17 having sludge adhered is also restrained. After that, the nut 14A at the end of the manual rotation shaft 14 is clamped by a tool and rotated by main guide to rotate the support width 31 of the oil cleaning means 3 and both sludge scraping plates fixed to the support width 31. By rotating 32, the sludge adhering to the inner peripheral wall of the stationary stationary cleaning tank 17 is scraped off for additional cleaning.

Although such sludge removal work seems to be simple in appearance, there are many problems such as manual operation and enormous amount of sludge production, and it is never desirable in use.

[0012] The main reason for this is that the amount of sludge generated by an oil purifier used in a general factory is considerably large and must be frequently removed. Often, one hour to one and a half hours of oil cleaning work is required. The removal work is required each time.

However, as described above, since the sludge removal work is manually performed, sometimes the operator is busy and forgets to remove the sludge, and a large amount of sludge is attached to the cleaning tank 17, resulting in the high sludge. The viscous sludge thickly accumulates, and a considerable amount of force is exerted just to manually rotate the hand-held shaft 14 and a great burden is put on the worker. In particular, if the removal work is not done for a long time, the hand-held shaft 14 may not be able to rotate. At this time, unless the entire cleaning tank 17 and its related members are excluded, the sludge inside can be cleaned. It is not possible and is therefore very inconvenient to use.

[0014]

[Problems to be solved by the device]

 In view of the problem of driving the sludge scraping plate in the conventional oil purifier described above, the present invention has a cleaning device and a sludge scraping plate to which sludge has adhered, which are rotated at different speeds by a driving unit to remove the sludge scraping plate. It is an object of the present invention to provide a sludge scraping plate drive device in an oil purifier that is relatively easy and convenient.

[0015]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention rotates a belt pulley by driving a main motor, and the belt pulley causes a cleaning tank to be interlocked with a hollow rotating main shaft to rotate relative to a central axis of the rotating main shaft. Sludge scraping plate in an oil purifier in which a possible auxiliary shaft is axially inserted, a sludge scraping plate is provided at its tip, and the slave shaft is manually controlled to rotate the sludge scraping plate indirectly interlockingly. In the drive unit, transmission gears having different numbers of teeth are attached to the rotating main shaft and the auxiliary shaft, and an idler equipped with an upper and lower interlocking gears having different numbers of teeth that mesh with these transmission gears is driven and rotated by a sub motor. From the rotation of the idler, an appropriate difference is generated in the rotational speeds of the two transmission gears so that the rotating main shaft and the auxiliary shaft are mechanically operated to rotate when the main motor is stopped. .

Then, both ends of the shaft rod on which the idler is inserted are axially seated on a shaft seat which is vertically opposed to the upper and lower end surfaces of the machine base, and a sub motor is provided immediately above an appropriate position near the idler. A drive gear is provided around a shaft rod extending downward of the sub motor, and further, the drive gear is engaged with an interlocking gear either above or below the idler so that the idler can be interlockedly rotated. Attach a pneumatic cylinder near the sub motor at an appropriate distance, connect the interlocking rod to the bottom end of the piston shaft that extends downward in the pneumatic cylinder, and pivot one end of the swing arm to the lower end of the interlocking rod to swing it. At the other end of the moving arm, a sandwiching part with a two-fork-shaped rubber washer is formed.In addition, arcuate rubber washers are fixed inside the sandwiching part, respectively, to hold the idler engaging block body in a cuddle. Further, it is more preferable that the interlocking gear of the idler is moved up and down along the shaft rod by driving the pneumatic cylinder so as to be engaged with or disengaged from the both transmission gears.

[0017]

[Function of the device]

 Since the present invention is configured as described above, when the main motor is started and rotated, the belt pulley rotates the rotating main shaft in an interlocking manner to proceed to rotate the cleaning tank, whereby the recovered oil is introduced from the return oil introduction pipe. It is possible to introduce impurities into the clean tank and to filter and filter impurities and dirt contained in the recovered oil by centrifugal force.

On the other hand, when cleaning the sludge adhering to the cleaning tank, first stop the rotation of the main motor, then engage the interlocking gears with different fractions at the top and bottom of the idler with the above transmission gears respectively, and use the sub motor to interlock the top and bottom. When the gears are driven and rotated, the rotary main shaft and the sub shaft are driven at different rotational speeds through the respective transmission gears fitted and fixed to the rotary main shaft and the sub shaft, respectively. By rotating at a speed different from that of the above-mentioned clean tank, sludge adhering to the surface of the clean tank can be removed.

Then, both ends of the shaft rod on which the idler is inserted are axially seated on a shaft seat vertically opposed to the upper and lower end faces of the machine base, and a sub motor is provided immediately above an appropriate position near the idler. A drive gear is provided around a shaft rod extending downward of the sub motor, and the drive gear is meshed with an interlocking gear either above or below the idler so that the idler can rotate in an interlocked manner. Install a pneumatic cylinder in the vicinity of a distance, connect the interlocking rod to the bottom end of the piston cylinder extending downward of the pneumatic cylinder, and pivot one end of the swing arm to the lower end of the interlocking rod to swing the swing arm or the like. A nipping portion having a two-fork-shaped rubber washer is formed at the end, and in addition, an arcuate rubber washer is fixed inside each nipping portion to hold and embrace the engagement block body of the idler. Further, by driving the pneumatic cylinder to move the interlocking gear of the idler up and down along the shaft rod so as to engage or disengage with both transmission gears, the idler smoothly moves along the shaft rod to move both transmissions. The occlusal action for each meshing part of the gear is more reliable.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

[0021]

【Example】

 As shown in FIGS. 1 and 2, the sludge scraping plate drive device of the present invention is provided above the machine base A2 on the side of the belt pulley A1 of the transmission means A, and mainly includes the sub motor N, the drive gear 4, and the upper and lower ends. Is formed by an idler 10 provided with interlocking gears 5 and 6, and a pushing means 7 for moving the idler 10 up and down, and a transmission gear 8 is provided at the upper end of the auxiliary shaft A3 of the transmission means A. Among them, the sub motor N is fixedly installed on the upper surface of the machine base A2, and the shaft rod N1 thereof is pushed downward into the machine base A2 and connected to the drive gear 4 by the key N2.

In addition, shaft seats B1 are mounted above and below the drive gear 4 and the belt pulley A1, respectively, and a shaft rod B2 is pivotally installed between the shaft seats B1 and B1. The idler 10 is pivoted on the body.

As shown in FIG. 1, the interlocking gears 5 and 6 above and below the idler 10 are provided at the upper and lower ends of the idler 10 so as to face each other, and the interlocking gear 5 forms a gear having 41 teeth around its circumference. The lower interlocking gear 6 is provided with a gear having 40 teeth, which is slightly smaller than the upper interlocking gear 5, on the outer peripheral surface thereof. The idler 10 having the vertical interlocking gears 5 and 6 on the upper and lower sides is pivoted by the shaft rod B2 and can be moved up and down along the shaft rod B2 under the control of the pushing means 7.

Next, as shown in FIGS. 2 and 3, the pushing means 7 drives the interlocking rod 72 to move up and down by the pneumatic cylinder 71 mounted on the machine base A 2 near the sub motor N. The bottom end of the interlocking rod 72 is pivotally connected to one end of the swing arm 73, the central portion of the swing arm 73 is pivotally mounted on the upper end of the support seat 74, and the other end of the swing arm 73 is provided with a two-fork-shaped holding portion 731. Then, the arcuate rubber washers 75 are fixed to the insides of the holding portions 731 to hold and hold the idler 10 body.

Therefore, when the pneumatic cylinder 71 drives the interlocking rod 72 and moves it upward or downward, the holding portion 731 of the swing arm 73 moves upward or downward, and at the same time, the upper and lower interlocking gears 5, 6 The idler 10 body formed by the above can be sandwiched and slid upward or downward along the axial rod B2.

As shown in FIG. 1, the one transmission gear 8 which is externally fitted and fixed to the auxiliary shaft A3 is positioned above the belt pulley A1 of the electric drive means A, and has a meshing portion 81 of 80 teeth on the outer peripheral edge of the ring body. The meshing portion 81 is formed so that it can mesh with the gear on the outer peripheral portion of the upper interlocking gear 5, and the belt pulley A1 below the electric gear 8 is driven and rotated by the main motor P via the belt A4. Further, the transmission gear A11 having 81 teeth is fixedly contacted directly above the belt pulley A1 so that it can be meshed with the outer peripheral gear of the lower interlocking gear 6.

As shown in FIG. 1, when performing the oil cleaning operation with the oil cleaner of the present invention, the belt pulley A1 is rotated via the belt A4 by rotating the main motor P in the same manner as the conventional one. A5 is rotated in conjunction (the fine adjustment spiral device is provided on the bottom seat to which the main motor P is fixed to adjust the fixed position of the main motor P, and the tension of the belt A4 is adjusted appropriately). The tank A6 is rotated (this partial structure is the same as the conventional one, and the description is omitted).

As a result, the collected oil that has flowed in from the return oil introducing pipe 8 is filtered by the centrifugal force to attach the contained impurities, impurities and dirt to the clean tank A6.

When cleaning the sludge adhering to the cleaning tank A6 according to the present invention, first, the rotation of the main motor P is stopped and then the piston shaft of the pneumatic cylinder 71 is driven, as shown in FIGS. Then, it extends downward to move the interlocking rod 72 downward.

At this time, the holding portion 731 of the swing arm 73 is raised by the downward movement of the interlocking rod 72, and drives the held idler 10 upward.

Therefore, the meshing portions 53, 63 at the outer peripheral edges of the upper and lower motion gears 5, 6 individually mesh with the transmission gear 8 of the countershaft A3 and the electric gear A11 directly above the belt pulley A1.

After that, when the sub motor N is started and rotated, either the upper or lower interlocking gears 5 and 6 can be rotated by the interlocking of the drive gear 4, and the idler 10 integrally connects the upper and lower interlocking gears 5 and 6. It can be driven and rotated, and by extension, the meshed transmission gears 8 and A11 can be simultaneously rotated.

In particular, the present invention is designed with the number of teeth of each of the upper and lower interlocking gears 5 and 6 differing by one tooth (while the number of the upper transmission gears is 8 from the lower transmission gear A11). In this situation, a differential speed action can be formed in the meshing relationship between the up / down interlocking gears 5 and 6 and both transmission gears A1 and 8, so that the sub motor N makes one revolution. Then, due to the differential speed action, different rotational speeds are formed between the rotating main shaft A5 and the auxiliary shaft A3 which are finally interlocked and rotated (the rotating speed of the cleaning tank is slightly slow, and the rotation of the sludge scraping plate is The speed is a little faster).

That is, the cleaning tank A6 and the sludge scraping plate A7 are driven by the same sub-motor N. However, due to the difference in the number of teeth of the respective transmission gears, the rotation speed of the auxiliary shaft A3 is the rotation main shaft A5. It is slightly faster than the rotation speed of. Then, the rotary main shaft A5 indirectly drives and rotates the cleaning tank A6, and the auxiliary shaft A3 indirectly drives and rotates the sludge scraping plate A7. Therefore, the sludge scraping plate A7 is driven by the difference in rotation speed between the two. Then, the sludge in the clean tank A6 is removed under the clean tank A6 whose rotation speed is slightly slow, and the effect of removing sludge by the sub motor is fulfilled.

Of course, the above-mentioned structure can be operated at a fixed time by manual control, but it is also possible to combine an electric control circuit according to the actual state to perform automatic removal operation at a fixed time. The sludge can be removed more smoothly by alternately rotating the forward and reverse rotations at regular intervals during the sludge removing operation, so that manpower can be saved and cost can be reduced.

On the other hand, the removed sludge falls into a loading means (not shown) such as a trolley provided below the cleaning tank A6, and the loading means uses a lower turntable to pass the oil cleaning through an orbit. Carry it away from the machine appropriately and process it intensively.

[0037]

[Effect of device]

 In the present invention configured as described above, the cleaning tank and the sludge scraping plate are driven by the same sub motor, but since the upper and lower transmission gears are designed to have different numbers of teeth, The rotation speed of the rotating shaft is slower than that of the rotating main shaft, and the rotating main shaft indirectly drives and rotates the cleaning tank, and the rotating shaft indirectly drives and rotates the sludge scraping plate. Due to the difference in the rotation speed, the sludge scraping plate is used to remove the sludge in the clean tank under the high rotation speed of the clean tank, and the sludge removal effect by the mechanical force is effectively achieved.

[0038] In addition, an electric control circuit is combined according to the actual use condition so that the automatic deletion operation is performed at a constant interval for a fixed time, or a normal rotation and a reverse rotation operation are alternately performed at a constant interval during the sludge removing operation. By doing so, sludge can be removed more smoothly, manpower can be saved, cost can be reduced, and sludge removal work can be performed easily and easily.
