The present invention relates to an oil separation device of a waste oil container treatment system, and more particularly, an oil separation efficiency through the formation of a flow path of a shaft diameter and a shaft diameter gradually increasing, which is gradually narrowed toward the discharge port, and a shaft diameter and a shaft center gradually increasing. Maximize and extend the end of the screw shaft so as to protrude from the outlet of the filter paper conveying pipe so that the filter paper is not clogged even without passing through the narrow portion and can be conveyed and discharged without difficulty, and can be stably supported without lateral fluctuation of the shaft core. An oil separation apparatus of a waste oil container processing system for facilitating separation and assembly between a screw shaft and a filter paper conveying pipe supporting the shaft.

In general, an oil filter is essential to a vehicle using oils such as control oil and lubricating oil so that the oil can be cleaned to continuously perform desired performance.

These oil filters must be replaced with new ones after a reasonable period of time, and the used waste oil filter contains a large amount of waste oil that cannot be removed. For reference, the oil filter is composed of a metal case and a filter paper inserted in the metal case. In other words, the used waste oil filter is in a state in which waste oil is contained in the filter paper.

Conventionally, a waste oil filter containing waste oil has been commonly used to temporarily store the waste oil at a place and compress or incinerate at once. However, such a waste oil contained in the filter paper inside the case during disposal is used. The pollution caused by this combustion was not only serious but also a problem of environmental pollution causing some soil to leak to the ground and polluting the soil.

The same applies to containers with lubricating oil.

Recently, in order to prevent such pollution and soil pollution, a system for treating waste oil filters and lubricating oil empty containers (iron cans) has been utilized.

As shown in FIG. 1, the waste oil filter and the lubricating oil empty container (iron can) are treated with a crusher 100 for crushing the waste oil filter and the lubricating oil empty container (iron can) and the crushed oil from the crusher 100. A transfer conveyor 200 for transferring the crushed products of the waste oil filter and the lubricating oil empty container (iron can), a magnetic separator 300 provided on one side of the transfer conveyor 200 to sort scraps of metal components, and the magnetic separator It consists of an oil washer (400) for separating the oil remaining in the scrap of the metal component to be screened to 300, and an oil separator (600) for separating the oil remaining in the filter paper transported along the transfer conveyor (200) The waste oil filter and the lubricating oil empty container (iron can) and a plurality of storage tanks 700 capable of collecting waste oil are included in the configuration.

In particular, since the waste oil filter is crushed without removing the filter paper, a device for separating the waste oil deposited on the filter paper is very important.

The conventional oil separator 600 applied to the waste oil container processing system such as the waste oil filter and the lubricating oil empty container (iron can) is shown in FIG.

Inlet 621 is formed to receive the filter paper of the waste oil container crushed in the crusher, the outlet 622 is formed in the opposite direction of the inlet 621, a plurality of through holes in the vicinity of the outlet 622 A filter paper conveying pipe 620 having a predetermined inner diameter 623 formed therein;

A screw-type crimping means 640 for separating oil from the filter paper by rotationally driving by rotational driving force of the motor 630 to press-press the filter paper in the filter paper conveying pipe 620;

It is composed of a collecting tank 650 to collect the oil flowing out through the through hole 623 to the outside of the filter paper conveying pipe 620 to collect in one place,

An outlet portion 622 of the filter paper conveying pipe 620 has a narrower diameter portion 624 whose inner diameter is gradually narrowed to further increase the crimping of the filter paper which is pushed out through the outlet 622 by the pressing means 640 to separate the oil. To improve the efficiency.

However, such a conventional oil separation device has the following problems.

First, the crimping means for compressing and transporting waste oil adhered to the filter paper, that is, the interval between the screw blades of the screw shaft is constant from the inlet to the outlet, so there is no problem in conveying, but there is a problem in that the crimping efficiency is lowered.

Secondly, the shaft diameter of the screw shaft of the crimping means is parallel to the inner diameter of the filter paper conveying tube, so that there is almost no crimping action in the conveying process of the filter paper, and the compression is rapidly performed near the narrow part, so that an excessive load is applied to the screw shaft. There is a problem losing.

Third, although the shape of the filter paper conveying pipe has a narrow portion in which the diameter of the filter is gradually narrowed in the vicinity of the outlet, it is intended to increase the oil separation efficiency of the filter paper. It could not be pushed out enough to cause a fatal problem of clogging the outlet of the bottleneck section. This problem leads to a problem caused by excessive operating load on the motor or, in severe cases, the filter paper transport pipe itself to burst.

Fourth, in the case where the through hole of the transfer pipe is blocked by the filter paper or when the screw shaft and the filter paper transfer pipe are to be separated in order to wash the inside of the transfer pipe as a whole, the A / S is not possible at all because there is no such consideration in the conventional apparatus.

The present invention was created to solve the above-mentioned problems, the object is,

First, the spacing between the blades of the screw shaft is gradually narrowed from the start end of the inlet to the end of the outlet to increase the compression efficiency.

Second, the shaft diameter of the screw shaft is configured to gradually widen from the beginning of the inlet to the end of the outlet to increase the oil separation efficiency of the filter paper with the first purpose.

Third, in order to maximize the oil separation efficiency with the first and second purposes by forming a separate flow path for discharging oil from the filter paper at the shaft center of the screw shaft.

Fourth, by extending the end of the screw shaft so as to protrude from the discharge port of the filter paper conveying pipe so that even if the filter paper passes through the narrow portion without being clogged and conveyed without difficulty.

Fifth, it is to facilitate the separation of the screw shaft and the filter paper conveying pipe supporting the shaft to increase the convenience for the internal cleaning of the conveying pipe or when the through-hole is blocked.

The present invention to achieve the above object,

Inlet is formed to receive the filter paper of the crushed waste oil container, the outlet of the narrow state is formed in the opposite direction of the inlet and the filter paper conveying pipe having a predetermined inner diameter with a plurality of through holes and the rotational drive by the rotational driving force of the motor Waste oil having a screw shaft for compressing and separating the oil from the filter paper by pressurizing the filter paper in the filter paper conveying pipe, and a collecting tank for collecting and collecting the oil flowing out through the through hole through the hole outside the filter paper conveying pipe. In the oil separation device of the container processing system,

The interval between the screw blades of the screw shaft is formed to narrow gradually from the inlet to the outlet, and the shaft diameter of the screw shaft is configured to gradually increase toward the narrower portion.

In addition, the present invention for achieving the above object,

A radial thin tubular tube is formed on the screw shaft, and an integrated flow path for integrating the tubular tube at the shaft center is formed to extend to the end of the shaft, and the integrated flow path is formed to form a separate drainage pipe to be connected to the collecting pipe. Have

In addition, the present invention for achieving the above object,

The end of the screw shaft has a feature that is formed to protrude to the outside of the outlet of the filter paper feed pipe.

In addition, the present invention for achieving the above object,

The filter paper conveying pipe is installed to be assembled to the collecting tank, the narrow portion has a feature that is installed separately from the filter paper conveying pipe.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 3 is a side cross-sectional view and enlarged view of the main portion of the oil separation device of the waste oil container treatment system according to the present invention, Figure 4 is a cross-sectional view taken along line A-A.

As shown in Figure 3, the oil separation device of the present invention,

Inlet 11 is formed to receive the filter paper of the crushed waste oil container, the outlet 12 in a narrow state is formed in the opposite direction of the inlet 11, the through-holes 13 are arranged in a line in a radial direction It has a filter paper conveying pipe 10 having a plurality of constant inner diameter formed.

As shown in FIGS. 3 and 4, the through hole 13 of the transfer pipe 10 is not directly formed on the inner diameter of the pipe, but has a step-shaped air gap guide groove 14 having a step at a portion where the through hole 13 is located. ), And a large number is formed in a line in the groove. The reason for the formation of the air gap guide groove 14 is that in the conventional case of the phase of the through hole such as the inner diameter of the filter feed pipe, the filter paper blocks the through hole during the transfer of the filter paper, so that the load due to the screw compression in the portion may be greatly generated. In addition, the compression efficiency is not very high. The void guide groove 14 of the present invention can solve this problem, even if any filter paper blocks any part of the void guide groove 14 during transport, and the hole 13 is open and the void guide groove is also open. (14) Since itself is formed in the form of a straight line from the inlet 11 to the outlet 12 of the filter paper conveying tube 10, no specific load is generated for any portion.

In addition, a reduction gear 21 for decelerating the rotational driving force of the motor 20 and the driving rotational force at a predetermined speed and driving force transmission means for transmitting the rotational driving force of the motor 20, that is, pulleys 22a, 22b and the belt 23 And a screw shaft 30 for squeezing and separating the oil from the filter paper by pressurizing and pressing the filter paper in the filter paper conveying pipe 10 by rotationally driving by organic bonding.

In addition, it has a collecting tank 40 to collect the oil flowing through the through hole 13 to the outside of the filter paper conveying pipe 10 to collect in one place.

More specifically, the present invention is formed so as to gradually narrow the interval between the screw blades 32 of the screw shaft 31 from the inlet 11 to the outlet 12 to increase the crimping efficiency of the filter paper, the screw shaft The shaft diameter of (31) is formed to increase gradually toward the narrower portion (15) of the filter paper feed pipe (10) so as to double the compression efficiency with the narrowing of the screw blades 32 interval.

On the other hand, while forming a radial narrow tubular tube 33 on the screw shaft 31 and at the end of the integrated channel 34 for integrating the tubular tube 33 in the shaft center of the screw shaft 31 to the shaft end portion; It is formed so as to, the integrated flow path 34 forms a separate drain pipe 41 to be connected to the collecting pipe (40).

The reason for the configuration of the tubular tube 33 and the integrated channel 34 is that the extrusion direction of the waste oil when the filter paper is pressed is not directed toward the through hole 13 but also toward the screw axis 31. In order to collect the waste oil coming in the direction of the axis 31 to increase the efficiency of collecting the waste oil to the filter paper as well as to reduce the excessive load generated in the narrow portion 15.

The starting point of the tubular tube 33 and the integrated flow path 34 is preferably formed from the midpoint of the screw shaft 31 to the end of the shaft where the compression is in earnest.

In addition, a bearing mechanism 42 is formed between the end of the screw shaft 31 and the oil pipe 41. The bearing mechanism 42 is a screw shaft 31 which is a rotating body and an oil pipe 41 which is a fixed body. To connect them together.

The bearing mechanism 42 is inserted into the socket 42a for connecting the end of the screw shaft 31 and the oil pipe 41, and the inner diameter of the socket 42a, as shown in FIG. The bearing 42b for guiding the rotation of the screw shaft 31, the oil ring 42c interposed inside and outside the bearing 42b to prevent leakage of waste oil, and the screw shaft. And a lock nut 42d which is screwed to the end of 31 to fix the bearing 42b.

On the other hand, the end of the screw shaft 31 is formed to protrude to the outside of the outlet 12 of the filter paper transport pipe (10). In the conventional screw shaft, since the end stays inside the filter paper conveying pipe, more specifically, the narrow part of the filter paper conveying pipe, clogging may occur near the outlet corresponding to the bottleneck section, and the discharge may not be sufficient. Although the load was significant, this problem does not occur because the screw shaft 31 of the present invention completely guides the filter paper until it is discharged to the outside.

In addition, the filter paper conveying pipe 10 is installed to be assembled to the reservoir 40, the narrow portion 15 has a configuration that is assembled separately from the filter paper conveying pipe (10).

That is, the first assembling portion S on the inlet 11 side, the second assembly portion T with the narrower portion 15 so that the tube diameter is gradually narrowed, and the narrower portion 15 with the collecting tank 40 The second assembly portion (U), the divided configuration of these assembly parts to facilitate the separation of the screw shaft 31 from the filter paper conveying pipe 10 to the filter shaft conveying pipe 10 as well as the screw shaft 31. This is to clean the inside of the machine.

The technical spirit of the present invention is not limited thereto, and various changes of the preferred embodiments of the present invention described can be made unless the spirit of the present invention is defined in the claims. Make it clear to you.

Applying the present invention as described above has the following advantages.

First, the spacing between the blades of the screw shaft is gradually narrowed from the beginning of the inlet to the end of the outlet, and the shaft diameter of the screw shaft is gradually widened from the beginning of the inlet to the end of the outlet. By forming separate tubular and integrated flow paths for discharging oil from the filter paper, the compression efficiency and the oil separation efficiency for the filter paper are significantly increased as compared with the prior art.

Second, by extending the end of the screw shaft so as to protrude from the discharge port of the filter paper conveying pipe, the filter paper is transported and discharged without being blocked even if it passes through the narrow portion, it can significantly reduce the load of the motor, as well as a stable filter paper transport action The transverse axial deflection of the screw shaft is not generated at all.

Third, ease of separation and assembly of the screw shaft and the filter paper conveying pipe (including the narrow portion) supporting the shaft, the convenience for the internal cleaning of the screw shaft and the conveying pipe is increased.
