Description

Technical Field

[0001] The utility model relates to the technical field of oil collection, in particular to a filter-pressing and flow-dividing integrated oil recovery device. Background Art

[0002] In order to maintain the performance of mechanical equipment, a large amount of engine oil is used during its operation and maintenance. To avoid engine oil waste, part of the oil is usually recovered. Most of the existing oil recovery equipment adopts a pump body with an oil extraction pipe and an oil extraction bottle structure. The oil is extracted into the oil extraction bottle through the pump body. However, a single oil extraction pipe requires the staff to constantly change the position of the oil extraction pipe to extract oil from multiple locations of the equipment. Usually, after the oil extraction at the current location is completed, the oil extraction pipe is moved to another set location to continue the oil extraction work. This working method is relatively cumbersome and takes a lot of time. The overall oil extraction efficiency is low. After the oil extraction, it is usually necessary to concentrate the oil extracted from the oil extraction bottle into the oil tank. In addition, the engine oil seeping out of the mechanical equipment usually contains a large amount of impurities. The existing oil extraction bottle is usually filtered by a filter screen, and the oil is filtered by passing through the filter screen under the action of its own weight. Since the oil has a certain viscosity and poor fluidity, it is very easy to adhere to the filter screen, resulting in low filtration efficiency and poor filtration effect.

[0025] During operation, the air pump 13 extracts air from the oil bottle 1, and under a negative pressure state, oil is extracted through the oil inlet pipe 11 and several shunt pipes 12, so that oil can be recovered from multiple locations of the equipment at the same time, thereby improving the oil recovery efficiency.

When the annular piston 51 rises, the one-way valve 23 at the oil extraction pipe 21 opens, and the one-way valve 23 at the oil supply pipe 22 closes, and the oil at the oil bottle 1 is extracted to the annular cavity 5.

[0026] Embodiment 2:

[0027] Reference Figures 1 to 5 Combined with the technical solution of Example 1, in this embodiment, a driving rod 81 is movable in the inner cavity of the cylinder 3, and the driving mechanism 8 is a driving cylinder. The driving cylinder is transmission-connected to the driving rod 81 and can drive the driving rod 81 to move. A first driving assembly 82 and a second driving assembly 83 are provided on the driving rod 81. The first driving assembly 82 is used to drive the annular piston 51 to move, and the second driving assembly 83 is used to drive the plunger 41 to move.

[0028] Specifically, the first driving assembly 82 includes a connecting frame 821, a spring 822 and an abutment ring 823. The connecting frame 821 is movably installed on the driving rod 81. The spring 822 and the abutment ring 823 are both arranged on the driving rod 81. The lower end of the connecting frame 821 is connected to the annular piston 51.

[0029] Specifically, the second driving assembly 83 includes a limit frame 831 and a limit rod 832. The limit frame 831 is set on the driving rod 81. The limit rod 832 is movably installed on the limit frame 831 and connected to the plunger 41. The upper end of the limit rod 832 is provided with an abutment portion that can abut against the bottom of the limit frame 831.

[0030] Working principle:

[0031] After the annular piston 51 draws the oil into the annular chamber 5, the driving cylinder drives the driving rod 81 to descend. During the descending process of the driving rod 81, the spring 822 abuts the abutting cylinder against the abutting ring 823, and the abutting cylinder drives the annular piston 51 to move downward, the one-way valve 23 at the oil supply pipe 22 is opened, and the one-way valve 23 at the oil extraction pipe 21 is closed, and the oil is squeezed to the filter element 7. At this time, the limit frame 831 moves downward relative to the limit rod 832, and the plunger 41 remains stationary. After the annular piston 51 abuts against the mounting block 2, the driving rod 81 continues to descend, the spring 822 is continuously compressed, and the lower end of the limit frame 831 abuts against the plunger 41 and pushes the plunger 41 to descend. During the descending process of the plunger 41, air is squeezed to the airbag 61, and the airbag 61 is expanded and squeezes the oil at the filter element 7 to the collecting bottle 9, which plays a certain filtering effect. After the work is completed, the driving cylinder drives the driving rod 81 to rise. At this time, the limit frame 831 rises relative to the limit rod 832, the plunger 41 remains stationary, the spring 822 gradually returns to its original position, and the annular piston 51 remains stationary. When the driving rod 81 rises to the connecting frame 821 and abuts against the abutment ring 823, the driving rod 81 drives the annular piston 51 to rise, the one-way valve 23 at the oil supply pipe 22 is closed, and the one-way valve 23 at the oil extraction pipe 21 is opened, and the oil is extracted from the oil bottle 1 to the annular cavity 5. When the driving rod 81 rises to the abutment part of the limit rod 832 and abuts against the limit frame 831, the limit frame 831 drives the limit rod 832 to rise, the plunger 41 rises and extracts the air at the airbag 61, the airbag 61 shrinks, and the driving rod 81 moves up and down to repeat the above-mentioned continuous oil pressure filtration work, which is beneficial to improving the oil filtration efficiency and filtration effect.

[0032] Embodiment 2:

[0033] Reference Figures 1 to 5 Combining the technical solutions of Example 1 and Example 2, in this embodiment, an exhaust pipe 24 and an air supply pipe 25 connected to the connecting pipe 4 are provided on the mounting block 2, and a pressure valve 26 is provided at both the exhaust pipe 24 and the air supply pipe 25.

[0034] Specifically, a core tube 6 is threadedly provided on the mounting block 2 , the core tube 6 is communicated with the connecting tube 4 , and the air bag 61 is sleeved and provided on the outer periphery of the core tube 6 .

[0035] During the descending process of the plunger 41, the airbag 61 continues to expand and squeezes out the oil at the filter element 7. When the air pressure inside the airbag 61 reaches the threshold value of the pressure valve 26 at the exhaust pipe 24, the pressure valve 26 opens to exhaust air, ensuring that the internal pressure of the airbag 61 can be maintained at the set value and can effectively prevent the airbag 61 from bursting.

[0036] During the rising process of the plunger 41, the air at the airbag 61 is continuously drawn to the connecting tube 4, and the airbag 61 shrinks and tightly adheres to the outer periphery of the core tube 6. When the negative pressure inside the airbag 61 reaches the threshold of the pressure valve 26 at the air supply pipe 25, the pressure valve 26 opens, and outside air enters the connecting tube 4, which helps to ensure that there is sufficient air inside the connecting tube 4 and can cooperate with the next descending process of the plunger 41 so that the airbag 61 can fully expand for pressure filtration.

[0037] Specifically, the filter element 7 is detachably connected to the mounting block 2 in a threaded connection manner.

[0038] Specifically, the collecting bottle 9 is detachably connected to the mounting block 2 in a threaded connection manner.

[0039] Specifically, the collecting bottle 9 is provided with an air hole 91 communicating with the outside air.

[0040] By arranging the air hole 91 on the collecting bottle 9 to balance the internal and external air pressure of the collecting bottle 9, the air bag 61 can expand or contract freely, ensuring that the oil at the filter element 7 can be squeezed out smoothly.

[0041] The above are only preferred embodiments of the present invention, and do not limit the present invention in any form.
