Description

Technical Field

[0002] Lubricating oil ultrafiltration equipment is a kind of equipment used for purifying lubricating oil.

[0003] Marine lubricating oil ultrafiltration equipment is specially designed for purifying lubricating oil on board ships. Due to the particularity of marine mechanical equipment, the lubricating oil on board is often affected by various factors such as seawater salinity, mechanical wear, metal chips, etc., which leads to serious lubricating oil pollution and affects the normal operation of mechanical equipment.

[0020] Beneficial Effects

[0021] The present invention provides a lubricating oil ultrafiltration device. Compared with the prior art, it has the following beneficial effects:

[0022] (1) When the lubricating oil ultrafiltration device needs to filter the lubricating oil on board, the filtration and water content absorption detection can be linked to each other. The top block is pushed upward by the connecting spring. When the top block moves to the rebound plate, since the stiffness coefficient of the rebound spring is greater than the stiffness coefficient of the connecting spring, as the hydrophilic and oleophobic block continues to absorb water and expand, it begins to squeeze the connecting spring to deform until the rebound spring is pushed to elastically deform and shorten, and the upper end of the top block pushes the rebound plate to rotate into the rebound cavity. At this time, the top block moves to the alarm switch, so that the alarm light works and an alarm is sounded, thereby realizing an alarm for excessive water content in the lubricating oil.

[0023] (2) In the lubricating oil ultrafiltration device, when the rebound plate rotates into the rebound chamber, the rebound plate and the power connection sheet are fitted together, and the power connection sheet is connected to the circuit between the controller and the motor, so that the motor works, drives the two-way reciprocating screw to rotate, drives the moving plates at both ends to approach each other, and drives the sliding block to move through the connecting rod, thereby pushing the squeezing plates on both sides of the hydrophilic oleophobic block to approach each other, so as to squeeze the hydrophilic oleophobic block, squeeze the water in the hydrophilic oleophobic block and pass through the water leakage plate into the water receiving chamber. As the motor continues to work, the two squeezing plates are driven away from the hydrophilic oleophobic block. At this time, the water in the hydrophilic oleophobic block is squeezed out, so as to move the squeezing plates, the upper end of the hydrophilic oleophobic block moves down again, leaves the alarm switch, stops the alarm, and stops the motor when passing through the rebound plate. After the water absorption is completed, the water in the hydrophilic oleophobic block is automatically squeezed. There is no need to manually replace the hydrophilic oleophobic block or manually squeeze it, thus achieving an automated effect.

[0024] (3) In the lubricating oil ultrafiltration device, when the squeezing plate moves horizontally to squeeze the hydrophilic and oleophobic blocks, the push rod connected to the slide groove pulls the slide groove to move, thereby driving the slide rod to rotate. Through the limiting effect of the limiting slide groove, the slide rod rotates, and the second connecting rod is pulled downward. When the two second connecting rods move downward, the lower ends of the double leaves of the collecting flap are pulled to flip. In conjunction with the setting of the slide groove, the double leaves of the collecting flap move downward from the middle, and the second connecting rod moves to both ends to open. Through the connection of the first connecting rod, the filter screen is flipped open at the same time. At this time, the controller senses the operation of the motor and controls the valve to block the oil inlet pipe to stop refueling. When the hydrophilic and oleophobic blocks are water recovered, the filter screen can be automatically flipped, so that impurities in the lubricating oil contaminated by seawater salt, mechanical wear, metal chips, etc. on the ship can fall into the collection box through the collecting flap, completing the cleaning process of the filter screen, thereby increasing the effective working time of the device, improving the filtration efficiency, and eliminating the need for frequent replacement and maintenance by humans.

The fluorocarbon diazo graphene material generally has a certain expansion property. After absorbing water, it can be passed through The water is discharged by squeezing. Since the fluorocarbon diazo graphene has an expansion property, when it absorbs water, the material structure will change, resulting in an increase in volume. By applying external pressure or squeezing, the water will be gradually squeezed out of the material to achieve the discharge process. A connecting spring 23 is fixed to the upper end of the hydrophilic and oleophobic block 21. A top block 22 is provided at the upper end of the connecting spring 23. The top block 22 slides in the water absorption chamber 14. The lower end of the transfer chamber 16 is connected to the water absorption chamber 14. The side wall of the lower end of the water absorption chamber 14 is connected to the oil collection chamber 25. An alarm switch 39 is provided on the upper wall of the water absorption chamber 14.

[0039] Extrusion mechanisms are provided on both side walls of the hydrophilic and oleophobic block 21 , and a matching transmission mechanism is provided in the control cavity 6 .

[0040] Embodiment 2:

[0041] See also Figure 1-Figure 8 This embodiment provides a technical solution based on the first embodiment:

[0042] The elastic component 40 includes a rebound chamber 401 opened in the side walls on both sides of the upper end of the water absorption chamber 14, a rebound plate 402 is rotated at the opening of the rebound chamber 401, a rebound spring 403 is provided between the rebound plate 402 and the lower end side wall of the rebound chamber 401, and an electric connection plate 404 is also provided on the side wall of the rebound chamber 401, and the electric connection plate 404 works in cooperation with the transmission mechanism.

[0043] It should be noted that the top block 22 is pushed upward by the connecting spring 23. When the top block 22 moves to the rebound plate 402, since the stiffness coefficient of the rebound spring 403 is greater than the stiffness coefficient of the connecting spring 23, as the hydrophilic and oleophobic block 21 continues to absorb water and expand, it begins to squeeze the connecting spring 23 and deform it, until the rebound spring 403 is pushed to elastically deform and shorten, and the upper end of the top block 22 pushes the rebound plate 402 to rotate into the rebound cavity 401. At this time, the top block 22 moves to the alarm switch 39, so that the alarm light 4 works and an alarm is sounded, thereby realizing an alarm for excessive water content in the lubricating oil.

[0044] In an optional embodiment: the opening mechanism includes two second connecting rods 28 that are respectively movable on the lower wall of the double pages of the collecting flap 20, and a sliding rod 30 is provided at the lower end of the two second connecting rods 28. The corresponding second connecting rods 28 and the sliding rod 30 are rotatably connected by a rotating shaft 31, and a limiting assembly is provided on the side wall of the rotating shaft 31. A sliding groove 29 is provided under the sliding rod 30, and the lower end of the sliding rod 30 is slidably set in the sliding groove 29.

[0045] It should be noted that when the hydrophilic and oleophobic blocks 21 are being used to recover moisture, the filter screen 19 can be automatically flipped over so that the filtered impurities can fall into the collection box 18 through the collection flap 20, thereby completing the cleaning process of the filter screen 19, increasing the effective working time of the device, improving the filtering efficiency, and eliminating the need for frequent manual replacement and maintenance.

[0046] In an optional embodiment: the limiting assembly includes a limiting slot 33 opened on the side wall of the collecting chamber 17, a limiting rod 32 is slidably provided in the limiting slot 33, the limiting rod 32 passes through the rotating shaft 31, and the limiting rod 32 and the rotating shaft 31 are movably connected.

[0047] It should be noted that, through the limiting action of the limiting slide groove 33, the slide rod 30 is rotated, and the second connecting rod 28 is pulled downward. When the two second connecting rods 28 move downward, the lower ends of the double pages of the collecting flap 20 are pulled to flip.

[0048] In an optional embodiment: the extrusion mechanism includes a water squeezing plate 38 arranged on the side walls on both sides of the lower end of the hydrophilic and oleophobic block 21, and mesh plates 26 are correspondingly provided on the side walls on both sides of the lower end of the water absorption chamber 14. Push rods 34 are fixed on the side walls on which the two water squeezing plates 38 are away from each other, and a sliding block 35 slides on the push rod 34. A limit block 37 is also provided on the side wall of the push rod 34. The limit block 37 is set between the water squeezing plate 38 and the sliding block 35. A reset spring 36 is also connected between the sliding block 35 and the limit block 37. A connecting rod 11 is fixed on the side wall of the sliding block 35, and the sliding block 35 is connected to the transmission mechanism through the connecting rod 11.

[0049] It should be noted that the squeezing plates 38 on both sides of the hydrophilic oleophobic block 21 are pushed closer to each other to squeeze the hydrophilic oleophobic block 21, squeeze the water in the hydrophilic oleophobic block 21 and pass through the water leakage plate 41 into the water collecting chamber 24. As the motor 9 continues to work, the two squeezing plates 38 are driven away from the hydrophilic oleophobic block 21. At this time, the water in the hydrophilic oleophobic block 21 is squeezed out. Therefore, as the squeezing plates 38 move, the upper end of the hydrophilic oleophobic block 21 moves down again, leaves the alarm switch 39, stops the alarm, and when passing through the rebound plate 402, the motor 9 stops working. After the absorption of water is completed, the water in the hydrophilic oleophobic block 21 is automatically squeezed. There is no need to manually replace the hydrophilic oleophobic block 21 or manually squeeze it, thereby achieving an automated effect.

[0050] In an optional embodiment: the transmission mechanism includes a bidirectional reciprocating screw 8 arranged in the control chamber 6, one end of the bidirectional reciprocating screw 8 is matched with a motor 9, both ends of the bidirectional reciprocating screw 8 are matched with a moving plate 10, the two moving plates 10 are respectively connected one by one through two connecting rods 11 and two sliding blocks 35, a corresponding connecting groove 12 is opened on the side wall of the reaction chamber 5, and the connecting rod 11 is arranged through the connecting groove 12.

[0051] It should be noted that the motor 9 works to drive the bidirectional reciprocating screw 8 to rotate, drive the moving plates 10 at both ends to approach each other, and drive the sliding block 35 to move through the connecting rod 11, thereby pushing the water squeezing plates 38 on both sides of the hydrophilic and oleophobic blocks 21 to approach each other, thereby squeezing the hydrophilic and oleophobic blocks 21.

[0052] In an optional embodiment: a collecting box 18 is provided at the lower wall of the collecting chamber 17 , and the collecting box 18 and the collecting flap 20 are arranged correspondingly.

[0053] It should be noted that the impurities and the like that fall down through the collection flap 20 can enter the collection box 18 and be collected.

[0054] In an optional embodiment: a valve is provided in the oil inlet pipe 2 , and the controller 7 is electrically connected to the valve, the alarm light 4 , and the motor 9 respectively, for controlling the working state of the valve and the motor 9 according to the working state of the alarm light 4 .

[0055] It should be noted that, while the double leaves of the collecting flap 20 move downward from the middle, the second connecting rod 28 moves to both ends and opens, and through the connection with the first connecting rod 27, the filter screen 19 is flipped open at the same time. At this time, when the controller 7 senses that the motor 9 is working, the control valve blocks the oil inlet pipe 2 to stop refueling, so that when the hydrophilic and oleophobic blocks 21 are used to recover moisture, the filter screen 19 can be automatically flipped, so that the filtered impurities can fall into the collection box 18 through the collecting flap 20, completing the cleaning process of the filter screen 19, increasing the effective working time of the device, improving the filtration efficiency, and eliminating the need for frequent manual replacement and maintenance.

[0056] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0057] When the ultrafiltration device is working, the controller 7 controls the valve to open, and the lubricating oil to be treated is added from the oil inlet pipe 2, and the lubricating oil falls into the filter chamber 15, and falls into the transfer chamber 16 after being filtered by the filter screen plate 19, and flows from the lower end of the transfer chamber 16 to the hydrophilic oleophobic block 21. The hydrophilic oleophobic block 21 absorbs the water in the lubricating oil, and the lubricating oil after the water absorption flows from the lower end of the water absorption chamber 14 into the oil collection chamber 25, and then can be recovered through the oil outlet pipe 3;

[0058] In the above process, when the hydrophilic oleophobic block 21 absorbs water in the lubricating oil, the hydrophilic oleophobic block 21 absorbs water and expands, and its upper end moves upward, and pushes the top block 22 to move upward through the connecting spring 23. When the top block 22 moves to the rebound plate 402, since the stiffness coefficient of the rebound spring 403 is greater than the stiffness coefficient of the connecting spring 23, as the hydrophilic oleophobic block 21 continues to absorb water and expand, it begins to squeeze the connecting spring 23 to deform, until the rebound spring 403 is pushed to elastically deform and shorten, and the upper end of the top block 22 pushes the rebound plate 402 to rotate into the rebound cavity 401. At this time, the top block 22 moves to the alarm switch 39, so that the alarm light 4 works and alarms, thereby realizing an alarm for excessive water content in the lubricating oil;

[0059] When the rebound plate 402 rotates into the rebound chamber 401, the rebound plate 402 and the power connection sheet 404 fit together, and the power connection sheet 404 is connected to the circuit between the controller 7 and the motor 9, so that the motor 9 works, drives the two-way reciprocating screw 8 to rotate, drives the moving plates 10 at both ends to approach each other, and drives the sliding block 35 to move through the connecting rod 11, thereby pushing the water squeezing plates 38 on both sides of the hydrophilic and oleophobic blocks 21 to approach each other, realizes the squeezing of the hydrophilic and oleophobic blocks 21, squeezes the water in the hydrophilic and oleophobic blocks 21 and enters the water receiving chamber 24 through the water leakage plate 41. As the motor 9 continues to work, the two squeezing plates 38 are driven away from the hydrophilic oleophobic block 21. At this time, the water in the hydrophilic oleophobic block 21 is squeezed out. Therefore, as the squeezing plates 38 move, the upper end of the hydrophilic oleophobic block 21 moves down again, leaving the alarm switch 39, and stops the alarm. When passing through the rebound plate 402, the motor 9 stops working. After the absorption of water is completed, the water in the hydrophilic oleophobic block 21 is automatically squeezed out. There is no need to manually replace the hydrophilic oleophobic block 21 or manually squeeze it, thus achieving an automated effect.

[0060] At the same time, in the above process, when the squeezing plate 38 moves horizontally to squeeze the hydrophilic and oleophobic block 21, the push rod 34 connected to the slide groove 29 pulls the slide groove 29 to move, thereby driving the slide rod 30 to rotate. Through the limiting effect of the limiting slide groove 33, the slide rod 30 rotates, and the second connecting rod 28 is pulled downward. When the two second connecting rods 28 move downward, the lower ends of the double pages of the collecting flap 20 are pulled to flip. With the setting of the slide groove 29, the double pages of the collecting flap 20 move downward from the middle, and the second connecting rod 28 moves to both ends to open. Open, through the connection of the first connecting rod 27, the filter screen plate 19 is flipped open at the same time. At this time, when the controller 7 senses that the motor 9 is working, the control valve is controlled to block the oil inlet pipe 2 to stop refueling, so that when the hydrophilic and oleophobic blocks 21 are used to recover moisture, the filter screen plate 19 can be automatically flipped, so that the filtered impurities can fall into the collection box 18 through the collection flap 20, completing the cleaning process of the filter screen plate 19, increasing the effective working time of the device, improving the filtering efficiency, and eliminating the need for frequent manual replacement and maintenance.
