Description

Technical Field

[0001] This invention relates to the field of kerosene purification technology, specifically to an aviation kerosene purification device with blockage monitoring and a blockage detection method. Background Technology

[0002] Aviation kerosene is a light petroleum product. Modern civil airliners are powered by turbojet engines, which propel the aircraft forward by burning fuel to generate thrust; the fuel used is called jet fuel.

[0003] Aviation kerosene is mainly produced by refining the kerosene fraction from crude oil distillation, or by distilling heavy distillate oil after hydrocracking. During the production process, trace components such as antioxidants and antistatic agents are also added.

[0004] In the production of aviation kerosene, it is necessary to purify the kerosene to prevent the quality of the kerosene from deteriorating due to impurities. Current purification methods usually remove impurities by filtering the oil. However, as the filtration time increases, the impurities remaining on the filter screen will affect the kerosene filtration rate, which requires cleaning the impurities. During the cleaning process, some of the oil remaining on the impurities will also be removed, resulting in oil waste. Summary of the Invention

[0005] The purpose of this invention is to provide an aviation kerosene purification device with blockage monitoring and a blockage detection method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] A cleaning component is disposed inside the filter tank and connected to the drive mechanism. The cleaning component is capable of operating when the drive mechanism moves to perform a tapping action on the filter screen.

[0013] An impurity discharge mechanism is disposed inside the filter press tube and connected to the drive mechanism. A conical disk is connected to the impurity discharge mechanism. When the drive mechanism moves, the impurity discharge mechanism can control the conical disk to move toward or away from the filter press disk.

[0014] As a further aspect of the present invention: the driving mechanism includes a motor fixedly installed on the top of the filter vessel, a transmission rod rotatably installed inside the filter vessel and connected to the output shaft of the motor, and a guide assembly connected to the transmission rod is provided inside the filter vessel.

[0015] As a further embodiment of the present invention: the guiding component includes a first spiral groove and a first annular groove formed on the transmission rod, the ends of the first spiral groove and the first annular groove are connected to each other, and the filter vessel is provided with a lifting structure connected to the first spiral groove and the first annular groove.

[0016] As a further embodiment of the present invention: the lifting structure includes guide columns fixedly installed inside the filter kettle and arranged symmetrically, the filter press plate is slidably connected to the guide columns and the transmission rod, a sliding sleeve is slidably installed on the transmission rod, a second limiting block is fixed on the inner wall of the sliding sleeve and slidably fitted with the first spiral groove and the first annular groove, and a second movable disc is fixed on the sliding sleeve and slidably connected to the guide column.

[0017] As a further embodiment of the present invention: the elastic filter press assembly includes a second support sleeve that is slidably mounted on the guide column and fixedly connected to the filter press disc. A second limiting ring that abuts against the second movable disc is fixed at the end of the second support sleeve. A second spring is sleeved on the second support sleeve, and the two ends of the second spring abut against the second movable disc and the filter press disc, respectively.

[0018] As a further embodiment of the present invention: the cleaning assembly includes a limiting plate fixedly installed on the transmission rod, and a vibrating rod is rotatably installed inside the filter tank. One end of the vibrating rod abuts against the limiting plate, and the other end of the vibrating rod cooperates with the filter screen.

[0019] As a further embodiment of the present invention: the impurity discharge mechanism includes a second annular groove, a second spiral groove, and a third spiral groove formed on the outer circumference of the transmission rod. The two ends of the second spiral groove are respectively connected to the ends of the second annular groove and the third spiral groove. A driven component connected to the transmission rod is provided on the guide post.

[0020] As a further embodiment of the present invention: the driven component includes a first movable disk slidably mounted on the guide post and slidably connected to the transmission rod, the inner wall of the first movable disk being fixed with a slidably fitted with the second annular groove, the second spiral groove and the third spiral groove, and a support structure connected to the first movable disk being provided on the guide post.

[0021] As a further embodiment of the present invention: the support structure includes a first support sleeve that is slidably mounted on the guide post and fixedly connected to the conical disk, the end of the first support sleeve being fixed with a first limiting ring that abuts against the first movable disk, and a first spring being sleeved on the transmission rod, the two ends of the first spring abutting against the first movable disk and the conical disk respectively.

[0022] A method for detecting blockages in an aviation kerosene purification device with blockage monitoring includes the following steps:

[0023] Step 1: Add the kerosene to be purified into the filter tank through the feed pipe, and filter the kerosene under the action of the filter screen;

[0024] Step 2: As impurities increase, the rate at which kerosene passes through the filter screen decreases, resulting in an increase in downward pressure on the conical disc, which in turn drives the impurity discharge mechanism to move.

[0025] Step 3: At this time, the drive mechanism will work and drive the elastic filter press assembly and the cleaning assembly to move. Under the action of the elastic filter press assembly, the filter press disc will move, and under the action of the cleaning assembly, the filter screen will be knocked.

[0026] Step 4: The drive mechanism will also drive the impurity cleaning mechanism to move, and with the cooperation of the filter plate and the conical plate, the filtered impurities will be filtered. When the conical plate moves into the collection tube, the impurities on the conical plate will enter the collection tube.

[0027] Compared with the prior art, the beneficial effects of the present invention are: the present application can automatically control the cleaning of the filter screen and impurities according to the amount of impurities and the filtration rate of the oil. Specifically, when the oil is added into the filter tank through the feed pipe, the oil is filtered under the action of the filter screen. The filtered impurities will fall onto the conical disk. As the impurities accumulate, or when the oil filtration rate decreases due to impurities remaining on the filter screen, resulting in too much oil on the conical disk, the conical disk will be controlled to move, thereby driving the impurity cleaning mechanism to move. An infrared sensor is installed on the first movable disk to detect the first movable disk. The distance between the disc and the conical disc is such that when the conical disc moves to a designated position, it indicates that impurities need to be cleaned. Under the action of the impurity cleaning mechanism, the drive mechanism is controlled to work. Under the action of the drive mechanism, the movement of the elastic filter press assembly and the impurity cleaning mechanism is controlled, thereby controlling the movement of the conical disc and the filter press disc. Under the action of the conical disc and the filter press disc, impurities are filtered to ensure that the oil is not wasted. After the filter press is completed, the conical disc enters the collection pipe to discharge the impurities into the collection pipe. Through the cooperation of the conical disc and the filter press disc, the effect of filtering impurities before discharging can be achieved.

[0028] The drive mechanism also drives the cleaning component to move. Under the action of the cleaning component, an impact force is applied to the filter screen, causing the filter screen to vibrate and vibrate the impurities remaining on the filter screen into the filter press tube, thereby ensuring that the filter screen will not reduce the filtration effect due to the blockage of impurities.

[0029] The impurity cleaning mechanism and the drive mechanism can adjust the distance between the filter press plate and the conical plate, so that the filtration can be carried out in the filter press tube. After the filtration is completed, the distance between the conical plate and the filter press plate is increased to ensure that impurities can be smoothly removed from the conical plate.

[0043] Please see Figures 1-10 In this embodiment of the invention, an aviation kerosene purification device with blockage monitoring includes:

[0044] The filter vessel 1, and the feed pipe 101 and discharge pipe 102 connected to the outer circumference of the filter vessel 1, the filter vessel 1 is fixed with a collection pipe 3, and the end of the collection pipe 3 is fixed with a filter press pipe 4.

[0045] Also includes:

[0046] Filter screen 2 is fixedly installed inside the filter tank 1 and fixedly connected to the filter press tube 4;

[0047] Please see Figures 1-4 , Figures 6-9 A drive mechanism is provided inside the filter vessel 1. The drive mechanism includes a motor 5 fixedly installed on the top of the filter vessel 1. A transmission rod 6 rotatably installed inside the filter vessel 1 and connected to the output shaft of the motor 5. A guide assembly connected to the transmission rod 6 is provided inside the filter vessel 1. The guide assembly includes a first spiral groove 601 and a first annular groove 602 formed on the transmission rod 6. The ends of the first spiral groove 601 and the first annular groove 602 are connected to each other. A lifting structure connected to the first spiral groove 601 and the first annular groove 602 is provided inside the filter vessel 1. The lifting structure includes guide columns 16 fixedly installed inside the filter vessel 1 and arranged symmetrically. The filter press 22 is slidably connected to the guide columns 16 and the transmission rod 6. A sliding sleeve 17 is slidably installed on the transmission rod 6. A second limiting block 18 is fixed on the inner wall of the sliding sleeve 17 and slidably fitted with the first spiral groove 601 and the first annular groove 602. A second movable disc 19 is fixed on the sliding sleeve 17 and slidably connected to the guide column 16.

[0048] In detail, the outer circumferential wall of the filter press tube 4 is provided with filter holes 401. The bottom of the collection tube 3 is connected to a conveying pipe, which is equipped with a valve. The valve can control the conduction state of the conveying pipe to discharge impurities in the collection tube 3. In the initial state, the second limiting block 18 is located at the end of the stroke of the first spiral groove 601 away from the first annular groove 602, so that the distance between the sliding sleeve 17 and the filter press tube 4 is maximized, and the second movable disk 19 is located at the end of the stroke away from the filter screen 2. When purifying kerosene, kerosene can be added into the filter kettle 1 through the feed pipe 101. The kerosene will fall onto the filter screen 2, and under the action of the filter screen 2, the impurities remaining in the kerosene will be filtered. Since the filter screen 2 is cone-shaped, under the action of gravity and the impact force generated by the flow of kerosene, the impurities remaining on the filter screen 2 will continuously enter the filter press tube 4 and fall onto the conical disk 13. As the impurities on the filter screen 2 and the conical disk 13 gradually increase, the filter screen 2 needs to be filtered. During the cleaning of impurities, motor 5 operates and drives transmission rod 6 to rotate, thereby causing the first spiral groove 601 and the first annular groove 602 to move. Under the action of the first spiral groove 601 and the second limiting block 18, the sliding sleeve 17 moves, thereby driving the second movable disc 19 to move along the length direction of the guide column 16. The guide column 16 has a guiding function, which can ensure that the second movable disc 19 will not rotate during movement. The second movable disc 19 will also drive the filter disc 22 to move through the elastic filter press assembly. When the filter disc 22 enters the filter press tube 4 and abuts against the conical disc 13, it can filter the impurities and kerosene located between the filter disc 22 and the conical disc 13, so that the kerosene remaining on the impurities flows back to the filter vessel 1 through the filter hole 401, ensuring that the filtered impurities do not contain kerosene, thereby avoiding the waste of kerosene during filtration. When the second limiting block 18 disengages from the first spiral groove 601 and enters the first annular groove 602, the second movable disc 19 stops moving.

[0049] Preferably, when impurities are transported into the collection pipe 3, the motor 5 controls the transmission rod 6 to reverse, causing the second movable disc 19 to move toward the initial position until the second limit block 18 returns to the end of the stroke of the first spiral groove 601, at which point the motor 5 stops working and repeats the above steps, thereby achieving the effect of automatically cleaning the impurities after filtration when the filter screen 2 is affected by impurities, resulting in a decrease in the filtration effect of kerosene, or when too many impurities are filtered and accumulate.

[0050] Please see Figures 2-4 , Figures 6-9The driving mechanism is provided with an elastic filter press assembly, and a filter press disc 22 that cooperates with the filter press tube 4 is connected to the elastic filter press assembly. The driving mechanism can drive the filter press disc 22 to move along the length direction of the filter press tube 4 through the elastic filter press assembly. The elastic filter press assembly includes a second support sleeve 20 that is slidably installed on the guide post 16 and fixedly connected to the filter press disc 22. A second limiting ring 21 that abuts against the second movable disc 19 is fixed at the end of the second support sleeve 20. A second spring 23 is sleeved on the second support sleeve 20. The two ends of the second spring 23 abut against the second movable disc 19 and the filter press disc 22, respectively.

[0051] It should be noted that, initially, the second spring 23 is compressed, causing the filter press 22 to tend to move away from the second movable disc 19, maximizing the distance between the filter press 22 and the second movable disc 19. At this time, under the action of the second support sleeve 20, the second limiting ring 21 abuts against the second movable disc 19. When impurities need to be cleaned, the motor 5 controls the transmission rod 6 to rotate, thereby controlling the second movable disc 19 to move towards the filter press tube 4. The second movable disc 19 also drives the second spring 23 to move. Under the action of the second spring 23, the filter press 22 moves synchronously with the second movable disc 19. When the filter press 22... When the kerosene enters the filter press tube 4, it will not enter the space between the filter press tube 4 and the conical disc 13 because the filter press disc 22 and the filter press tube 4 are in a sliding seal connection. At this time, the impurities are filtered by the filter press disc 22 and the conical disc 13 to squeeze out the residual kerosene through the filter hole 401. During the filtration process, the filter press disc 22 is subjected to resistance and compresses the second spring 23, thereby controlling the separation of the second limit ring 21 from the second movable disc 19 by the second support sleeve 20. Under the action of the second spring 23, it can ensure that the pressure provided by the filter press disc 22 to the impurities is sufficient, and it can also control the filter press disc 22 to give way to prevent the filter press disc 22 from interfering with the conical disc 13.

[0052] Please see Figure 2 , Figure 3 , Figure 6 A cleaning component is disposed inside the filter vessel 1 and connected to the drive mechanism. The cleaning component is able to operate when the drive mechanism moves to perform a tapping action on the filter screen 2. The cleaning component includes a limiting plate 7 fixedly installed on the transmission rod 6. A vibrating rod 8 is rotatably installed inside the filter vessel 1. One end of the vibrating rod 8 abuts against the limiting plate 7, and the other end of the vibrating rod 8 engages with the filter screen 2.

[0053] Furthermore, the outer circumference of the limiting disc 7 can be divided into two parts: a protrusion 701 and a recess 702, which are circumferentially equidistantly distributed. A torsion spring is installed on the rotating shaft of the vibrating rod 8. Under the action of the torsion spring, the end of the vibrating rod 8 facing the filter screen 2 tends to move towards the filter screen 2. In the initial state, the protrusion 701 abuts against one end of the vibrating rod 8, causing the other end of the vibrating rod 8 to separate from the filter screen 2. When the transmission rod 6 rotates, it drives the limiting disc 7 to rotate, causing the protrusion 701 to move towards the filter screen 2. The outlet 701 separates from the vibrating rod 8. Under the action of the torsion spring, the vibrating rod 8 swings rapidly at a certain angle, causing the other end of the vibrating rod 8 to strike the filter screen 2, thereby causing the filter screen 2 to vibrate. This causes the impurities remaining on the filter screen 2 to detach from the filter screen 2 and fall into the filter press tube 4. When the next protrusion 701 comes into contact with the vibrating rod 8, the vibrating rod 8 is controlled to return to its original position. The above steps are repeated to continuously apply an oscillating force to the filter screen 2, so as to control the impurities remaining on the filter screen 2 from entering the filter press tube 4 before the impurities are filtered.

[0054] Preferably, as the filter screen 2 is used for longer, more impurities remain on the filter screen 2. Therefore, under the action of the vibrating rod 8, the filter screen 2 can be cleaned by applying vibration force to ensure that the filter screen 2 can continuously filter kerosene. The kerosene filtered through the filter screen 2 will fall to the bottom of the filter tank 1. At this time, the valve of the discharge pipe 102 can be opened to discharge the cleaned oil.

[0055] Please see Figures 3-5 , Figure 7 , Figure 10An impurity discharge mechanism is disposed within the filter press tube 4 and connected to the drive mechanism. A conical disc 13 is connected to the impurity discharge mechanism. When the drive mechanism moves, the conical disc 13 can be controlled to move towards or away from the filter press disc 22. The impurity discharge mechanism includes a second annular groove 24, a second spiral groove 25, and a third spiral groove 26 formed on the outer circumference of the transmission rod 6. The two ends of the second spiral groove 25 are respectively connected to the ends of the second annular groove 24 and the third spiral groove 26. A driven component connected to the transmission rod 6 is disposed on the guide post 16, wherein the driven component includes components slidably mounted on the guide post 16. A first movable disk 9 is slidably connected to the transmission rod 6. The inner wall of the first movable disk 9 is fixed with a sliding engagement with the second annular groove 24, the second spiral groove 25, and the third spiral groove 26. A support structure connected to the first movable disk 9 is provided on the guide post 16. The aforementioned support structure includes a first support sleeve 11 slidably mounted on the guide post 16 and fixedly connected to the conical disk 13. A first limiting ring 12 that abuts against the first movable disk 9 is fixed at the end of the first support sleeve 11. A first spring 15 is sleeved on the transmission rod 6. The two ends of the first spring 15 abut against the first movable disk 9 and the conical disk 13, respectively.

[0056] Furthermore, both the second spiral groove 25 and the third spiral groove 26 are spirally arranged, and the pitch of the second spiral groove 25 is smaller than the pitch of the first spiral groove 601 and the third spiral groove 26, while the pitch of the third spiral groove 26 is larger than the pitch of the first spiral groove 601. An infrared sensor is installed on the first movable disk 9 to detect the distance between the first movable disk 9 and the conical disk 13. In the initial state, the first movable disk 9 is located at the end of the stroke of the second annular groove 24 facing the first annular groove 602, so that the first movable disk 9 is located at the end of the stroke away from the collecting pipe 3. The first spring 15 is in a compressed state, so that the distance between the conical disk 13 and the first movable disk 9 is maximized. At this time, under the action of the first support sleeve 11, the first limiting ring 12 is... When the filter screen 2 filters kerosene, the filtered impurities fall onto the conical disc 13, increasing the downward pressure on the conical disc 13. Furthermore, if too many impurities remain on the filter screen 2, the filtration rate decreases, leading to an increase in the amount of kerosene accumulating on the conical disc 13. Both of these situations indicate the need to clean the impurities and the filter screen 2. Therefore, under the influence of gravity, the conical disc 13 moves towards the first movable disc 9, compressing the first spring 15. When the distance between the conical disc 13 and the first movable disc 9 is less than a set value, the infrared sensor sends a signal. At this time, the motor 5 operates to control the rotation of the transmission rod 6. Under the action of the first spiral groove 601, the filter press 22 moves towards the conical disc 13. The first movable disc 9 moves in the direction of disc 13. At this time, under the action of the second annular groove 24 and the first limiting block 10, the position of the first movable disc 9 remains unchanged. When the first limiting block 10 disengages from the second annular groove 24 and enters the second spiral groove 25, the first movable disc 9 will move towards the collecting pipe 3. Since the pitch of the second spiral groove 25 is smaller than the pitch of the first spiral groove 601, the distance between the filter disc 22 and the conical disc 13 continuously decreases until the filter disc 22 applies downward pressure to the impurities on the conical disc 13. Under the action of the filter disc 22 and the conical disc 13, the impurities are filtered. The first spring 15 and the second spring 23 are compressed. Therefore, during the filtration process, the force exerted by the filter disc 22 and the conical disc 13 on the impurities gradually increases. The transmission rod 6 continues to rotate until the first limiting block 10 disengages from the second spiral groove 25 and enters the third spiral groove 26. Since the pitch of the third spiral groove 26 is greater than that of the first spiral groove 601, the movement speed of the conical disk 13 is greater than that of the filter press disk 22. The transmission rod 6 continues to rotate until the distance between the conical disk 13 and the filter press disk 22 gradually increases. At this point, the conical disk 13 is about to disengage from the filter press tube 4. The second limiting block 18 moves into the first annular groove 602, causing the filter press disk 22 to stop moving. The conical disk 13 continues to move and enters the collection tube 3. Since the conical disk 13 is cone-shaped, impurities will fall into the collection tube 3 under the action of gravity. After the impurities are discharged, the transmission rod 6 reverses, causing the filter press disk 22 and the conical disk 13 to reset.Repeat the above steps to automatically clean filter 2 and remove impurities.

[0057] Preferably, since a sealing sleeve 14 is fixed on the conical disc 13, when the first limiting block 10 is located in the second annular groove 24, the filter hole 401 is blocked by the sealing sleeve 14 to prevent the filtered oil from entering the filter press tube 4 and the collection tube 3 through the filter hole 401. During the filter press process, both the filter press 22 and the conical disc 13 are in the position of engaging with the filter hole 401 to ensure that the oil at the filter press can be discharged into the filter vessel 1 through the filter hole 401.

[0058] A method for detecting blockages in an aviation kerosene purification device with blockage monitoring includes the following steps:

[0059] Step 1: Add the kerosene to be purified into the filter vessel 1 through the feed pipe 101, and filter the kerosene under the action of the filter screen 2;

[0060] Step 2: As impurities increase, the rate at which kerosene passes through filter screen 2 decreases, resulting in an increase in downward pressure on conical disc 13, which in turn drives the impurity discharge mechanism to move.

[0061] Step 3: At this time, the drive mechanism will work and drive the elastic filter press assembly and the cleaning assembly to move. Under the action of the elastic filter press assembly, the filter press disc 22 will move. Under the action of the cleaning assembly, the filter screen 2 will be knocked.

[0062] Step 4: The drive mechanism will also drive the impurity cleaning mechanism to move, and with the cooperation of the filter plate 22 and the conical plate 13, the filtered impurities will be filtered. When the conical plate 13 moves into the collection pipe 3, the impurities on the conical plate 13 will enter the collection pipe 3.
