An oil removal device

Abstract

The present invention relates to an oil removal device, which relates to the technical field of oil removal and includes components such as a support assembly, an oil collection assembly, and an oil removal assembly. During the flow of the oil liquid, the oil liquid first passes through the oil outlet hole group located below. When the liquid level of the oil liquid in the barrel reaches the oil outlet hole group located above, the oil outlet hole group below and the oil outlet hole group above discharge oil simultaneously, which can avoid a relatively high height of the oil liquid inside the barrel, thereby avoiding the large oil discharge pressure of the oil outlet hole group below and causing spraying. Moreover, each of the oil outlet through holes has a first port communicating with the oil removal space and a second port communicating with the oil storage space, and the lowest point of the first port is higher than the highest point of the second port. When the oil liquid enters the oil storage space from the oil removal space through the oil outlet through hole, the oil liquid has a flowing process from top to bottom, and the oil liquid is not likely to splash everywhere, which is convenient for cleaning the oil removal device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the present invention, rather than to limit the present invention.

[0029] As Figures 1 to 5 shown, an oil removal device includes:

[0030] A support assembly 1, the support assembly 1 includes a base 11 and a support frame 12 provided on the base 11, and an installation space 110 is formed between the base 11 and the support frame 12.

[0031] An oil collection assembly 2, the oil collection assembly 2 is provided on the base 11 and an oil storage space 20 for collecting oil liquid is formed inside.

[0032] An oil removal assembly 3, the oil removal assembly 3 includes a barrel body 31, a driving member 32 and a pressing plate 33. The top of the barrel body 31 is open and an oil removal space 310 for containing the workpiece to be deoiled is formed inside. The barrel body 31 is provided on the oil collection assembly 2 and at least partially extends into the oil storage space 20. The inner bottom surface of the barrel body 31 corresponding to the oil removal space 310 is higher than the inner bottom surface of the oil collection assembly 2 corresponding to the oil storage space 20. The barrel body 31 is axially provided with at least two groups of oil outlet hole groups 311. Each group of the oil outlet hole groups 311 includes at least two oil outlet through holes 3111 arranged circumferentially along the barrel body 31. Each of the oil outlet through holes 3111 has a first port 31111 communicating with the oil removal space 310 and a second port 31112 communicating with the oil storage space 20. The lowest point of the first port 31111 corresponding to the same oil outlet through hole 3111 is higher than the highest point of the second port 31112. The driving member 32 is provided on the support frame 12. The pressing plate 33 is provided at the movable end of the driving member 32 and corresponds to the oil removal space 310. The driving member 32 is used to drive the pressing plate 33 to reciprocate in the oil removal space 310.

[0033] During the use of the oil removal device provided by the present invention, first place the oil-removing part to be processed into the oil removal space 310, and then drive the pressing plate 33 to reciprocate in the oil removal space 310 through the driving part 32. When the pressing plate 33 moves downward, it can squeeze the oil-removing part to be processed. The pressing plate 33 is preferably a pressing plate 33 whose cross-sectional area in the horizontal direction is smaller than that of the oil removal space 310. When the pressing plate 33 squeezes the oil-removing part to be processed, the liquid level of the oil will rise, and the pressure of the oil is mainly brought by its own gravity. Then, the squeezed oil can flow out through at least two groups of oil outlet hole groups 311. During the flow of the oil, the oil first passes through the lower oil outlet hole group 311. When the liquid level of the oil in the barrel 31 reaches the upper oil outlet hole group 311, the lower oil outlet hole group 311 and the upper oil outlet hole group 311 will discharge oil at the same time, which can prevent the liquid level of the oil inside the barrel 31 from being too high, thereby avoiding the large oil discharge pressure of the lower oil outlet hole group 311 and causing spraying. Each oil outlet through hole 3111 has a first port 31111 communicating with the oil removal space 310 and a second port 31112 communicating with the oil storage space 20. The lowest point of the first port 31111 is higher than the highest point of the second port 31112. When the oil flows from the oil removal space 310 through the oil outlet through hole 3111 into the oil storage space 20, the oil has a downward flow process from top to bottom, and the oil is not easy to splash everywhere, which is convenient for cleaning the oil removal device.

[0034] Among them, the oil-removing part to be processed can be an oil-absorbing cotton.

[0035] In order to prevent the oil from splashing everywhere, the cross-sectional area of the first port 31111 is smaller than that of the second port 31112. The oil outlet through hole 3111 is arc-shaped. The cross-sectional area of the oil outlet through hole 3111 gradually increases along the path from the first port 31111 to the second port 31112. In practical applications, when the oil flows from the oil removal space 310 through the oil outlet through hole 3111 into the oil storage space 20, the liquid pressure of the oil in the oil outlet through hole 3111 gradually decreases, and the flow velocity also relatively decreases. The oil is not easy to splash everywhere, which is convenient for cleaning the oil removal device.

[0036] In order to facilitate the discharge of the oil in the barrel 31, the lowest point of the lowermost first port 31111 is not higher than the inner bottom surface of the barrel 31 corresponding to the oil removal space 310, and the highest point of the lowermost first port 31111 is higher than the inner bottom surface of the barrel 31 corresponding to the oil removal space 310. Such a design facilitates the oil to flow out through the first port 31111, that is, it facilitates the discharge of the oil in the barrel 31.

[0037] To avoid oil splashing everywhere, the oil collecting assembly 2 includes a tank body 21 and a cover body 22. The top of the tank body 21 is open and an oil storage space 20 is formed inside. The cover body 22 is arranged on the top of the tank body 21 to at least partially block the top opening of the tank body 21. Setting the cover body 22 can further prevent oil from splashing everywhere. When the oil pressure of the oil flowing from the oil removal space 310 into the oil storage space 20 through the oil outlet through-hole 3111 is still relatively large, the oil may hit the side of the tank body 21, resulting in oil splashing everywhere. However, in actual application, the power of the driving member 32 can be reduced so that the reciprocating movement speed of the pressing plate 33 driven by the driving member 32 in the oil removal space 310 is relatively small, and the extrusion speed of the pressing plate 33 squeezing the workpiece to be deoiled during the downward movement is also relatively small, so that the oil pressure of the oil flowing from the oil removal space 310 into the oil storage space 20 through the oil outlet through-hole 3111 is relatively small. And setting the cover body 22 can further prevent oil from splashing everywhere and prevent special situations from occurring, such as: the staff adjusts the power of the driving member 32 too large due to an operation error.

[0038] To avoid oil splashing everywhere caused by the blockage of the oil outlet through-hole 3111, a filter screen 312 which is annular and coaxially arranged with the barrel body 31 is provided on the inner side surface of the barrel body 31 corresponding to the oil removal space 310. The filter screen 312 is used to filter the oil flowing into the oil outlet through-hole 3111. When the oil outlet through-hole 3111 is blocked, it is easy to cause the oil outlet pressure at the second port 31112 to become larger, resulting in oil splashing everywhere. By setting the filter screen 312, the oil flowing into the oil outlet through-hole 3111 can be filtered, and some impurities can be blocked, avoiding oil splashing everywhere caused by the blockage of the oil outlet through-hole 3111.

[0039] To facilitate the discharge of oil and avoid oil splashing everywhere, a groove 211 is formed on the inner bottom surface of the tank body 21 corresponding to the oil storage space 20, and an oil discharge pipe valve 212 communicating with the groove 211 is provided on the tank body 21. In actual application, a certain amount of oil can also be kept in the oil storage space 20, that is, the oil in the oil storage space 20 submerges at least one group of oil outlet hole groups 311, so that when the submerged oil outlet hole group 311 discharges oil, the situation of oil splashing everywhere will not occur. Then, the oil discharge pipe valve 212 can be appropriately opened to keep a certain amount of oil in the oil storage space 20 all the time, that is, the oil in the oil storage space 20 can always submerge at least one group of oil outlet hole groups 311.

[0040] To facilitate the discharge of oil, the groove 211 becomes deeper from inside to outside. Such a design can discharge the oil more thoroughly and is more convenient to use in actual application.

[0041] In order to avoid oil splashing everywhere, there are three sets of the oil outlet hole groups 311, and each set of the oil outlet hole groups 311 includes eight oil outlet through holes 3111. The opening sizes of the first port 31111 and the second port 31112 of the oil outlet hole group 311 can be adjusted according to the actual situation, the radian of the oil outlet through hole 3111 can also be adjusted according to the actual situation, and the distance between two adjacent oil outlet hole groups 311 can also be adjusted according to the actual situation. In practical applications, the above-mentioned dimensional parameters and application parameters can be determined according to the specific practical scenarios to avoid oil splashing everywhere.

[0042] The working principle of the oil removal device according to an embodiment of the present invention is as follows:

[0043] First, place the part to be deoiled into the oil removal space 310, and then drive the pressing plate 33 to reciprocate in the oil removal space 310 through the driving member 32. When the pressing plate 33 moves downward, it can squeeze the part to be deoiled. The pressing plate 33 is preferably a pressing plate 33 whose cross-sectional area in the horizontal direction is smaller than the cross-sectional area of the oil removal space 310. When the pressing plate 33 squeezes the part to be deoiled, the liquid level of the oil will rise, and the pressure of the oil is mainly brought by its own gravity. Then, the squeezed oil can flow out through at least two sets of oil outlet hole groups 311. During the flow of the oil, the oil first passes through the oil outlet hole group 311 located below. When the liquid level of the oil in the barrel 31 reaches the oil outlet hole group 311 located above, the oil outlet hole group 311 below and the oil outlet hole group 311 above will discharge oil at the same time, which can avoid the high liquid level of the oil inside the barrel 31, thereby avoiding the large oil discharge pressure of the oil outlet hole group 311 below and causing spraying. Each oil outlet through hole 3111 has a first port 31111 communicating with the oil removal space 310 and a second port 31112 communicating with the oil storage space 20. The lowest point of the first port 31111 is higher than the highest point of the second port 31112. When the oil flows from the oil removal space 310 into the oil storage space 20 through the oil outlet through hole 3111, the oil has a downward flow process from top to bottom, and the oil is not easy to splash everywhere, which is convenient for cleaning the oil removal device.

[0044] The above is only a preferred embodiment of the present invention, and it is not a limitation to any form of the present invention. Any simple modification and equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
