A deep sea equipment oil filter

Abstract

An oil filter for deep-sea equipment is used for filtering the oil of deep-sea equipment. The main structure consists of an outer shell, a bottom shell, an impeller, a phase rod, a diaphragm guide plate, a guide pressure plate, a filter frame, a return spring, a filter element, and a phase rod guide seat. The oil enters from the upper inlet of the outer shell, is pressurized by the impeller and flows to the filter element for filtration, and then flows out from the outlet below the bottom shell after filtration. When the filter element begins to be blocked due to the accumulation of particulate matter, the pressure difference between the upper and lower sides of the phase rod increases, and the axial movement of the phase rod simultaneously drives the diaphragm guide plate to rotate and switch the filter element. The device solves the problems of unreliable operation of electronic control components of deep-sea equipment for a long time and high cost of component replacement.

Description

Technical Field

[0001] The invention belongs to the field of deep-sea oil production equipment, and in particular relates to an oil filter for deep-sea equipment. Background Art

[0002] At present, the domestic deep-sea oil production field still faces many difficulties. In terms of deep-sea oil production equipment, there is a problem of high oil production costs. Deep-sea oil production equipment cannot work for a long time without a lubrication system. The cleanliness of the lubricating oil directly affects the service life and reliability of the oil production equipment. Lubricating oil contamination will lead to increased wear of equipment parts and even equipment shutdown.

[0003] On the other hand, the reliability of electronic components decreases rapidly after working in the deep-sea environment for a period of time, and electronic control equipment is not suitable for long-term deep-sea operations.

[0004] The cost of deep-sea operations by underwater robots is huge, and the current deep-sea robot manipulators have limited degrees of freedom and power. The cost of replacing parts for deep-sea equipment is high and difficult.

[0005] The present invention provides a deep-sea equipment oil filter which does not require electronic control elements or replacement of parts and can work reliably for a long time. Summary of the invention

[0006] The present invention is to solve the problem that the oil and oil filter of deep-sea equipment cannot be replaced for a long time. The present invention designs an oil filter that does not require manual replacement and remote control.

[0007] The technical solution adopted by the present invention to solve the above problems is: the present invention designs a deep-sea equipment oil filter, the filter element material uses metal rubber, the material has high strength and small filter particle diameter, and can ensure high oil pressure while filtering tiny particles in the oil. The present invention uses an impeller to provide power for filtering, and the impeller is connected to the motor or pump shaft in the oil production equipment through a transmission mechanism. After the filter is used for a period of time, the filter element will be blocked by tiny particles in the oil. At this time, the continuous operation of the impeller will cause the pressure difference between the bottom of the impeller and the two sides of the outlet to increase. At this time, the phase rod is pushed axially under the action of the pressure difference, and the front end of the phase rod enters the guide tooth of the phase rod guide seat and starts to rotate, squeezing the diaphragm and driving the diaphragm guide plate to rotate, thereby realizing the switching of the filter element. During the switching process, the diaphragm guide plate positioning spring pin can accurately locate the rotation position of the guide plate. When the oil flow channel switches to the next filter element, the pressure difference between the inlet and outlet of the filter is reduced, and the phase rod returns to its position under the action of the squeezed diaphragm and the return spring.

[0008] The technical advantage of the present invention is that the present invention provides a filtering device that can ensure the cleanliness of engine oil for a long time without replacement and control. Compared with current marine equipment, it has the advantages of deeper working water depth, small device size, no need for external control, and no need for filter element replacement.

[0029] like Figure 1 , Figure 2 , Fig.16 , Fig.17 , Fig.18 , Fig.19As shown, a deep-sea equipment oil filter includes an impeller 1, a housing 2, a phase rod 3, a bolt 4, a diaphragm guide plate 5, a guide pressure plate 6, a bottom shell seal 7, a diaphragm guide plate positioning spring pin 8, a guide pressure plate seal 9, a nut 10, a filter frame 11, a phase rod seal 12, a return spring 13, a phase rod guide seat 14, a phase rod guide seat screw 15, a filter element 16, and a bottom shell 17. When used, the impeller 1 is powered by an oil production device motor or pump, so that the oil maintains a certain pressure after entering from the upper inlet and is pressurized before entering the filter element 16. The oil enters the filter element 16 through the diaphragm guide plate 5 and is filtered before flowing out. When the filter element 16 is clogged due to the accumulation of particulate matter caused by long-term filtration, the flow resistance of the filter element 16 increases, and the pressure difference between the space below the impeller 1 and the bottom outlet increases, and the phase rod 3 is in contact with the environment below the impeller 1 and the outlet. The pressure difference causes the phase rod 3 to move axially and squeeze the diaphragm guide plate 5. The phase rod 3 enters the phase rod guide seat 14 and rotates. The phase rod 3 drives the diaphragm guide plate 5 to rotate and compresses the return spring 13. The diaphragm guide plate 5 is rotated and positioned by the diaphragm guide plate positioning spring pin 8. After positioning, the engine oil switches to the next filter element and is filtered. The pressure difference below the impeller 1 and on both sides of the outlet is reduced, and the phase rod 3 returns to its position under the squeezing force of the diaphragm guide plate 5 and the return spring 13.

[0030] Figure 3 The impeller 1 of the present invention is composed of an impeller shaft 101 and blades 102. The impeller shaft 101 is powered by a motor or pump mechanism of an oil production device.

[0031] Figure 4 The housing 2 of the present invention includes a bolt seat 201 and a diaphragm guide plate positioning ring 202. The diaphragm guide plate positioning ring 202 adopts a wave-shaped design, and its highest point is the position of the diaphragm guide plate positioning spring pin 8 when the filter is working normally. When the phase rod 3 drives the diaphragm guide plate 5 to rotate, the diaphragm guide plate positioning spring pin 8 slides along the diaphragm guide plate positioning ring 202 and is compressed at the same time. When it slides over the wave crest of the positioning ring 202 and enters the wave trough, the diaphragm guide plate 5 is accurately positioned.

[0032] Figure 5It is the phase rod 3 of the present invention, which includes a contact pressure plate 301, a contact plate guide tooth 302, a transmission rod 1 303, a return spring positioning seat 304, a transmission rod 2 305, and a transmission rod guide tooth 306. The phase rod 3 does not participate in the work when the device of the present invention is working normally. When the filter element 16 is blocked and the pressure difference between the bottom and the outlet of the impeller 1 increases, the contact pressure plate 301 squeezes the diaphragm guide plate 5, and the transmission rod guide tooth 306 rotates in the phase rod guide seat 14. At the same time, the contact plate guide tooth 302 drives the diaphragm guide plate 5 to rotate. The contact position between the transmission rod 1 303 and the filter frame 11 is sealed by the phase rod sealing ring 12 to ensure that the oil can only flow into the filter element 16 without other leakage. A return spring 13 is arranged outside the transmission rod 2 305, and its position is determined by the return spring positioning seat 304 to ensure that the return spring 13 works normally when the phase rod 3 rotates.

[0033] Figure 6 The diaphragm guide plate 5 of the present invention includes a diaphragm guide plate guide tooth 501, a diaphragm 502, a diaphragm guide plate positioning spring pin hole 503, and a diaphragm guide plate guide hole 504. The guide tooth 501 is meshed with the contact plate guide tooth 302 of the phase rod 3. The diaphragm guide plate positioning spring pin 8 is arranged in the diaphragm guide plate positioning spring pin hole 503. The diaphragm guide plate positioning spring pin 8 positions the rotation angle of the diaphragm guide plate 5. When the phase rod 3 rotates, the contact plate guide tooth 302 drives the diaphragm guide plate guide tooth 501 to rotate. The diaphragm guide plate guide tooth 501 and the contact plate guide tooth 302 are designed as one-way guides. When the phase rod 3 is squeezed and rotated by the return spring 13 to return to its original position, the diaphragm guide plate 5 does not rotate with it. The diaphragm guide plate guide hole 504 cooperates with the guide pressure plate 6 to ensure that the engine oil enters the corresponding filter element through the guide hole.

[0034] Figure 7 , Figure 8 The guide plate 6 of the present invention includes a guide plate guide hole 601, a phase rod through hole 602, a guide plate guide hole sealing ring groove 603, and a guide ring 604. The guide plate guide hole 601 matches with the diaphragm guide plate guide hole 504 of the diaphragm guide plate 5, the guide plate guide hole sealing ring groove 603 matches with the guide plate sealing ring 9, ensuring that the engine oil only flows to the corresponding filter element 16 without other leakage, and the guide ring 604 ensures that the engine oil smoothly enters the filter element 16 and is fully filtered.

[0035] Fig. 9The diaphragm guide disc positioning spring pin 8 of the present invention comprises a diaphragm guide disc positioning spring pin housing 801, a spring 802, and a base 803. The device is matched with the diaphragm guide disc positioning spring pin hole 503 of the diaphragm guide disc 5, the diaphragm guide disc positioning spring pin housing 801 is in contact with the diaphragm guide disc positioning ring 202 of the housing 2, and the base 803 is in contact with the diaphragm guide disc fixing platform 1701 of the bottom shell 17. When the diaphragm guide disc 5 rotates, the spring 802 slides from the trough of the diaphragm guide disc positioning ring 203 to the crest and is compressed at the same time. When sliding from the crest to the trough, the compressed spring 802 recovers its length to fix the positioning spring pin 8 at the trough position to realize the precise positioning of the diaphragm guide disc 5.

[0036] Fig.10 , Fig.11 The filter frame 11 of the present invention includes a through hole 1101 for matching the phase rod 3, a fixing plate 1102, a filter element frame 1103, a filter frame positioning pin hole 1104, a phase rod sleeve 1106, and a filter frame screw hole 1107. The phase rod 3 passes through the through hole 1101, the fixing plate 1102 is placed on the filter frame fixing platform 1704 of the bottom shell 17, the filter element 16 is placed in the filter element frame 1103, the filter frame positioning pin hole 1104 cooperates with the filter frame fixing pin 1702 of the bottom shell 17 to ensure that the position of the filter frame 11 is fixed, and the phase rod 3 is placed in the phase rod sleeve 1106. The bottom of the phase rod sleeve 1106 cooperates with the phase rod guide seat 14, and the guide seat screw hole 1107 cooperates with the phase rod guide seat screw 15 to fix the phase rod guide seat 14.

[0037] Fig.12 This is a cross-sectional view of the filter frame 11 of the present invention, and it can be seen that the filter frame 11 includes a phase rod sealing ring groove 1105, and the phase rod sealing ring 12 is arranged in the phase rod sealing ring groove 1105 to ensure that the camera oil does not flow in the gap between the transmission rod 303 of the position rod 3 and the phase rod sleeve 1106. At the same time, the position of the filter frame positioning pin hole 1104 and the filter frame screw hole 1107 can be seen from the figure.

[0038] Fig.13The phase rod guide seat 14 of the present invention includes a phase rod guide seat guide tooth 1401, a phase rod guide seat return spring positioning pin 1402, and a phase rod guide seat screw hole 1403. The device is fixed to the phase rod sleeve 1106 of the filter frame 11 through the phase rod guide seat screw hole 1403. When the phase rod 3 moves axially due to the pressure difference, its transmission rod guide tooth 306 cuts into the phase rod guide seat guide tooth 1401 and rotates. The phase rod guide seat return spring positioning pin 1402 cooperates with the return spring 13 to ensure that the return spring 13 is correctly deformed when the phase rod 3 rotates. At the same time, the design of the phase rod guide seat 14 allows a gap to be formed at the connection when it cooperates with the phase rod sleeve 1106, so that when the phase rod 3 moves axially, the oil in the gap between the phase rod 3 and the phase rod sleeve 1106 can be discharged or sucked in the gap between the phase rod guide seat 14 and the phase rod sleeve 1106.

[0039] Fig.14 The filter element 16 of the present invention is made of metal rubber, which has high strength and can filter particles with small diameters, meeting the requirements of oil filtration. The filter element 16 is placed in the filter element frame 1103 of the filter frame 11, and the upper inlet cooperates with the guide ring 604 of the guide pressure plate 6, so that the oil can smoothly enter the filter element 16 through the guide hole 601 of the guide pressure plate 6 and be effectively filtered.

[0040] Fig.15 The bottom shell 17 of the present invention includes a diaphragm guide plate fixing platform 1701, a filter frame fixing pin 1702, a bottom shell sealing ring groove 1703, a filter frame fixing platform 1704, and a nut seat 1705. The diaphragm guide plate fixing platform 1701 cooperates with the diaphragm guide plate 5, and the base 803 of the diaphragm guide plate positioning spring pin 8 slides on the plane when the diaphragm guide plate 5 rotates. The filter frame fixing pin 1702 cooperates with the filter frame positioning pin hole 1104 of the filter frame 11. The bottom shell sealing ring groove 1703 is provided with a bottom shell sealing ring 7 to ensure that the outer shell 2 and the bottom shell 17 are tightly matched to prevent leakage of engine oil or seawater. The filter frame fixing platform 1704 cooperates with the fixing plate 1102 of the filter frame 11. The nut seat 1705 cooperates with the nut 10 and the bolt 4.
