Description

Technical Field

[0001] The present application relates to the technical field of natural gas filtration, and in particular to a natural gas pipeline filter and a method of using the same. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere and lithosphere. A natural gas pipeline refers to a pipeline that transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. Natural gas is transported using natural gas pipelines.

[0003] When natural gas pipelines transport natural gas, filters are usually required to filter and adsorb particles and moisture in the natural gas to ensure the purity of the natural gas. For example, in the related art, a Chinese patent application with publication number CN114702996A proposes a natural gas filter pressure wave oscillation cleaning device and a cleaning control method, which has the advantages of backblowing and cleaning the filter element when the filter pressure drop of the filter element reaches a set value or within a fixed time interval, thereby reducing the filter pressure drop, solving the problem of disposable use of the filter element, avoiding frequent replacement of the filter element, extending the life of the filter element, and reducing operating energy consumption and cost.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the pipeline filter filters natural gas, particles and moisture will accumulate and adhere to the filter element of the filter, and the particles and moisture in the filter need to be cleaned regularly. However, the current method for cleaning the filter particles and moisture requires staff to disassemble and clean the filter at regular intervals, and the natural gas pipeline needs to suspend the transportation of natural gas in the middle. This method is not only time-consuming and labor-intensive, but also affects the efficiency of natural gas transportation. If the pipeline filter is frequently disassembled and cleaned, it is easy to cause natural gas leakage, which will not only pollute the environment, but also easily cause fire and explosion, and the safety of the use of the pipeline filter cannot be guaranteed. Summary of the invention

[0005] In order to realize automatic cleaning of particles and dust in the filter, when cleaning the filter particles, there is no need to stop the natural gas pipeline from delivering natural gas, and there is no need to frequently disassemble and clean the pipeline filter.

[0008] By adopting the above technical solution, the space inside the filter box can be divided by the partition plate, the left space of the filter box can be used to transport natural gas, and the right space of the filter box can be used to adsorb particles and moisture on the filter frame. The two filter frames can be switched and adjusted by the switching component. When the left filter frame in the filter box is blocked, it can be switched with the cleaned right filter frame in the filter box. The detection component can be used to detect whether the left filter frame is blocked, and then the switching component can be controlled to switch the two filter frames. The two filter frames can be switched at any time without stopping the transmission of natural gas to clean the filter frames. The filter frames can be automatically switched and cleaned.

[0009] The positions of the drying component and the dust collection component can be adjusted through the adjustment component, and the filter frame can be adsorbed and cleaned in a multi-range manner. The drive shaft and the two power gears can be driven to rotate in turn by the motor, and the two filter frames can be driven to switch left and right respectively through the meshing relationship between the power gear and the transmission rack. The clogged filter frame can be moved to the right side of the partition plate for cleaning, and the cleaned filter frame can be moved to the left side of the partition plate to continue filtering the natural gas. There is no need to stop the transmission of natural gas to clean the filter frame, so as to ensure the effect of natural gas transmission.

[0010] Optionally, the drying component includes a drying box arranged on the inner side of the filter box, an absorbent cotton board arranged below the filter frame, a montmorillonite desiccant for absorbing moisture from the absorbent cotton board, a first reverse blade rotatably arranged on the inner side of the drying box, a detection member for detecting the moisture content of the montmorillonite desiccant, a power member for driving the first reverse blade to rotate, and a clamping member for disassembling and assembling the absorbent cotton board.

[0011] By adopting the above technical scheme, the right filter frame can be dried by the drying component, the moisture in the right filter frame can be adsorbed to ensure the dryness of the filter frame, the moisture on the filter frame can be adsorbed by the absorbent cotton board, the absorbent cotton board can be dried by the montmorillonite desiccant to speed up the speed of the absorbent cotton board adsorbing moisture on the filter frame, the power part can provide suction force, and the moisture adsorption effect of the absorbent cotton board and the montmorillonite desiccant can be further enhanced, the montmorillonite desiccant can be detected by the detection part, and it can be detected whether the montmorillonite desiccant can continue to absorb moisture, and the staff can be reminded to replace the montmorillonite desiccant, and the absorbent cotton board can be installed and disassembled by the clamping part, which can facilitate the replacement of the montmorillonite desiccant.

[0013] By adopting the above technical solution, the dust suction component can be used to absorb and clean the particles and dust in the right filter frame to ensure the cleaning effect of the filter frame. The suction force of the dust suction component can be automatically adjusted by the adjustment part, and the suction force of the dust suction component can be adjusted according to the number of particles on the filter frame to ensure the efficiency of the dust suction component in suctioning the filter frame.

[0014] Optionally, the detection component includes an air collecting funnel fixed on the inner side of the filter box, the right side of the air collecting funnel is fixedly connected to the left side of the partition plate, the inner side of the filter box is movably connected with a support rod, a power block is provided on the outer side of the support rod, ten power blades are provided on the outer side of the power block, the power blades are located below the opening at the bottom of the air collecting funnel, a supporting round block is provided at one end of the front side of the support rod, a power sheet is provided on the outer side of the support round block, a rubber belt is provided on the outer side of the power sheet, a sensor is provided on the front side of the filter box, the rubber belt is movably fitted with the sensor, and the sensor is electrically connected to the motor.

[0015] By adopting the above technical solution, the flow of natural gas can drive the ten power blades to rotate, the power sheet and the rubber belt to rotate in a circle, and the sensor can be hit intermittently. The filter frame can be detected by this method. When there are many particles on the filter frame and it is blocked, the flow speed of natural gas will be slower. The rotation speed of the ten power blades, the power sheet and the rubber belt will also be very slow due to the influence of the natural gas flow rate, and then the frequency of the rubber belt hitting the sensor is also very slow. When the sensor is hit at a slow frequency, the signal will be transmitted to the motor to drive it to switch the two filter frames.

[0016] Optionally, the adjustment assembly includes a drive box fixed to the filter box, a bidirectional motor is provided on the inner side of the drive box, power rods are provided on the output shafts at the top and bottom of the bidirectional motor, first bevel gears are provided on the outer sides of the two power rods, second bevel gears are meshed on the outer sides of the two first bevel gears, threaded rods are provided on the inner sides of the two second bevel gears, threaded blocks are threadedly connected to the outer sides of the two threaded rods, limiting blocks are provided on the outer sides of the two threaded blocks, support plates are provided on the outer sides of the two limiting blocks, electric push rods are provided on the outer sides of the two support plates, the bottom electric push rod is fixedly connected to the bottom of the drying box, and the top electric push rod is fixedly connected to the top of the dust collection box.

[0017] By adopting the above technical scheme, the two power rods, two first bevel gears, two second bevel gears and two threaded rods can be driven to rotate by the bidirectional motor respectively, and then the two threaded blocks, two limit blocks, two support plates and two electric push rods can be driven to move left and right respectively. When the top electric push rod moves left and right, it can drive the dust collection component to move left and right above the filter frame, which can improve the range and effect of the dust collection component on the adsorption of particles and dust on the filter frame. When the bottom electric push rod moves left and right, it will drive the drying component to move left and right below the filter frame in turn, which can improve the range and effect of the drying component on the adsorption of moisture on the filter frame.

[0018] Optionally, the power component includes a driving motor fixed on the inner side of the drying box, the output shaft of the driving motor is provided with a movable shaft, the movable shaft is fixedly connected to the first reverse blade, a third bevel gear is provided on the outer side of the movable shaft, a fourth bevel gear is meshed on the outer side of the third bevel gear, a fan blade shaft is provided on the inner side of the fourth bevel gear, fan blades are provided on the outer side of the fan blade shaft, an air outlet pipe is provided on the outer side of the drying box, the fan blades are located on the inner side of the air outlet pipe, a limiting frame is provided on the outer side of the regulating box, an air collecting funnel is provided on the bottom of the limiting frame, and the air collecting funnel is located directly above the air outlet pipe.

[0019] By adopting the above technical solution, the driving motor can sequentially drive the movable shaft, the first reverse blade, the third bevel gear, the fourth bevel gear, the fan blade shaft and the fan blade to rotate. When the first reverse blade rotates, suction will be generated, which can accelerate the speed at which the absorbent cotton board absorbs the filter frame. At the same time, when the absorbent cotton board absorbs moisture from the filter frame, the absorbent cotton board can be dried by the montmorillonite desiccant. The suction force generated by the rotation of the first reverse blade can accelerate the speed at which the montmorillonite desiccant dries the absorbent cotton board.

[0020] The transmission gear is meshed with a second gear on the outside of the transmission gear, and a connecting shaft is provided on the inside of the second gear, and the second reverse blade is fixedly connected to the connecting shaft; a connecting pipe is provided at the bottom of the dust suction box, and the six dust suction heads are connected with the connecting pipe; a dust collection box is provided on the outside of the dust suction box, and a dust inlet pipe is provided on the inside of the dust suction box; a dust suction chamber is provided on the inside of the dust suction chamber, and the second reverse blade is located on the inside of the dust suction chamber.

[0021] By adopting the above technical scheme, wind force will be generated when the fan blades rotate, which can drive ten wind blades to rotate with the wind force, and then drive the fan blade rod, the large speed regulating gear, the small speed changing gear, the connecting rod and the second reverse blade to rotate in turn to generate a strong suction force, and the particles and dust in the filter frame can be sucked into the inner side of the dust collection box through the six dust suction heads in turn for collection. The large speed regulating gear drives the small speed changing gear to rotate, and the connecting rod and the second reverse blade can be accelerated and accelerated, so that the fan blade rod can ensure the rotation speed of the second reverse blade even when it rotates at a low speed. The fan blade rod can also ensure a higher speed suction when the second reverse blade rotates at a low speed, and the rotation suction of the second reverse blade will not be affected by the large number of particles on the filter frame.

[0022] Optionally, the adjusting member includes a movable blade fixed on the outside of the fan blade rod, a connecting funnel is provided on the inner side of the adjusting box, a wind force plate is movably connected to the inner side of the adjusting box, an adjusting plate is provided on the right side of the wind force plate, a coil spring is provided on the outside of the wind force plate, the coil spring is fixedly connected to the adjusting box, the movable blade is located on the inner side of the connecting funnel, the wind force plate is located on the right side of the opening of the connecting funnel, and the dust inlet pipe and the second reverse blade are both located above the adjusting plate.

[0023] By adopting the above technical solution, when the fan blade rod rotates, it will also drive the movable blades to rotate and generate wind force. When there are more particles in the filter frame, the speed at which the wind blows into the air collecting funnel is relatively slow, and the wind force generated by the rotation of the movable blades is not enough to blow the wind plate and the adjustment plate to move in a wide range. When there are fewer particles inside the filter frame, the speed at which the wind blows into the air collecting funnel is relatively fast, so the speed at which the movable blades rotate will also be relatively fast, and then the rotating wind force of the movable blades can blow the wind plate and the adjustment plate to move in a wide range. The adsorption effect of the dust collection component can be controlled according to the number of particles inside the filter frame to enhance the adsorption effect of the dust collection component on the filter frame particles.

[0024] Optionally, the detection component includes two storage boxes fixed on the inner side of the drying box, the montmorillonite desiccant is filled in the inner sides of the two storage boxes, two detection boxes are arranged on the outer side of the drying box, the inner sides of the two storage boxes are movably connected with movable push plates, the outer sides of the two movable push plates are provided with connecting plates, the outer sides of the two connecting plates are provided with movable cone blocks, the outer sides of the two movable cone blocks are movably fitted with movable balls, the tops of the two movable balls are provided with movable rods, the tops of the two movable rods are provided with chirping blocks, the outer sides of the two movable push plates are provided with two telescopic springs, the telescopic springs are fixedly connected to the storage boxes, the tops of the two detection boxes are provided with storage grooves, the two chirping blocks are respectively located on the inner sides of the two storage grooves, and the bottom of the filter box is provided with a sound transmission tube.

[0025] By adopting the above technical solution, the volume of the montmorillonite desiccant will gradually increase over time while absorbing moisture from the absorbent cotton board, and the effect of moisture adsorption will also decrease. The top of the storage box is restricted by the absorbent cotton board, so the montmorillonite desiccant will push the movable push plate as its volume increases, causing the telescopic spring to be in a compressed state, which can in turn drive the movable push plate, the connecting plate and the movable cone block to move to the right, and then drive the movable ball, the movable rod and the chirping block to move upward, causing the chirping block to gradually move out of the storage slot, and the chirping block will fit and squeeze the filter frame to produce a chirping sound, which will be transmitted through the sound transmission tube to remind the staff that the montmorillonite desiccant needs to be replaced.

[0026] The second aspect of the present application provides a method for using a natural gas pipeline filter using the following technical solution:

[0027] The present application also discloses a method for using a natural gas pipeline filter, based on the above-mentioned natural gas pipeline filter, comprising the following steps:

[0028] S1. When natural gas flows through the air inlet pipe, filter box and outlet pipe, the filter frame can filter and absorb particles and moisture in the natural gas. When the natural gas flows, it can drive ten power blades to rotate, and can drive the rubber belt to rotate in a circle to intermittently hit the sensor to detect the filter frame. When there are many particles on the filter frame, the natural gas flow speed will be slower, and the frequency of the rubber belt hitting the sensor will also be slow, which will transmit the signal to the motor drive, drive the drive shaft and two power gears to rotate, and drive the two filter frames to switch left and right, and move the cleaned filter frame to the left side of the partition to continue filtering the natural gas;

[0029] S2. The bottom electric push rod can drive the absorbent cotton board to move up and down to fit the bottom of the filter frame, and the top electric push rod can drive the six dust collectors to move up and down to fit the top of the filter frame. The absorbent cotton board can absorb the moisture on the filter frame, and the driving motor drives the first reverse blade to rotate to generate suction, which speeds up the speed at which the absorbent cotton board absorbs moisture from the filter frame. When the absorbent cotton board absorbs moisture, the montmorillonite desiccant can dry the absorbent cotton board, and the suction force of the first reverse blade rotation speeds up the speed at which the montmorillonite desiccant dries the absorbent cotton board;

[0030] S3. As the montmorillonite desiccant is used for a long time, its volume will gradually increase when it absorbs moisture from the absorbent cotton board, and its moisture absorption will also decrease. When the volume of the montmorillonite desiccant increases, it will drive the movable cone block to move to the right, and will drive the movable ball and the chirping block to move upward, squeezing the filter frame to produce a chirping sound, which will be transmitted through the sound transmission tube to remind the user that the montmorillonite desiccant needs to be replaced;

[0031] S4. The fan blades of the driving motor are driven to rotate to generate wind force, which can drive the ten wind blades to rotate, and then drive the second reverse blades to rotate. When the second reverse blades rotate, strong suction force is generated, and the particles and dust in the filter frame can be sucked into the inner side of the dust box through six dust suction heads and dust inlet pipes for collection;

[0032] S5. The ten wind blades can also drive the movable blades to rotate to generate wind blowing on the wind plate. The spiral spring can be compressed to drive the adjustment plate to move left and right to adjust the gap size of the dust suction chamber. When there are many particles in the filter frame, the speed of wind blowing into the wind collecting funnel is relatively slow, and the speed of the movable blades will also be slow, which is not enough to blow the adjustment plate to move in a wide range. When there are fewer particles inside the filter frame, the speed of wind blowing into the wind collecting funnel is relatively fast, and the speed of the movable blades will also be fast. Then the movable blades can blow the adjustment plate to move in a wide range, and the adsorption effect of the six dust suction heads can be controlled according to the number of particles inside the filter frame;

[0033] S6. The two threaded rods can be driven to rotate by the bidirectional motor, thereby driving the two electric push rods to move left and right. When the top electric push rod moves left and right, it can drive the six vacuum heads to move left and right on the filter frame, thereby increasing the range of the six vacuum heads to adsorb particles and dust on the filter frame. When the bottom electric push rod moves left and right, it can drive the absorbent cotton board to move left and right under the filter frame, thereby increasing the range of the absorbent cotton board to adsorb moisture on the filter frame, thereby ensuring the filter frame's effect on natural gas adsorption and filtration.

[0034] By adopting the above technical scheme, the filter frame can be dried and adsorbed and cleaned in a multi-range manner, and the suction force can be automatically adjusted according to the number of particles on the filter frame. When there are fewer particles on the filter frame, the suction force will also become smaller, thereby avoiding wear of the filter frame due to excessive suction force, thereby ensuring the cleaning effect of the filter frame. When there are more particles on the filter frame, the suction force will also become larger, thereby avoiding the filter frame impression caused by too small suction force affecting the cleaning effect of the filter frame, and the particles and dust on the filter frame can be effectively adsorbed and cleaned.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. During the transmission of natural gas, the filter frame can filter and absorb the particles and moisture in the natural gas. The gas collecting funnel can first concentrate the natural gas to drive the ten power blades to rotate, and then drive the power block, power sheet and rubber belt to rotate in a circle to intermittently hit the sensor. When there are many particles on the filter frame and it is blocked, the natural gas flow rate will be slow. The rotation speed of the ten power blades and rubber belt is also very slow due to the influence of the natural gas flow rate. The frequency of the rubber belt hitting the sensor is also very slow. The sensor will transmit the signal to the motor to drive, and the two filter frames are switched and adjusted. The motor drive switching assembly is driven to move the blocked filter frame to the right side of the partition plate for cleaning, and the cleaned filter frame can be moved to the left side of the partition plate to continue filtering the natural gas, so as to achieve the purpose of automatic cleaning of the filter frame particles, and there is no need to suspend the natural gas pipeline to transport the natural gas in the middle;

[0037] 2. The absorbent cotton board can be fitted with the bottom of the filter frame by adjusting the adjustment components, and the six dust collector heads can be fitted with the top of the filter frame. The absorbent cotton board can absorb the moisture on the filter frame. When the driving motor drives the first reverse blade to rotate, suction will be generated, which can speed up the absorption speed of the absorbent cotton board on the filter frame. At the same time, when the absorbent cotton board absorbs moisture from the filter frame, the montmorillonite desiccant inside the two storage boxes can dry the absorbent cotton board. The suction force of the first reverse blade rotating can speed up the absorption speed of the montmorillonite desiccant on the absorbent cotton board. The drying speed can further enhance the speed and effect of the absorbent cotton board on the moisture absorption of the filter frame. The volume of the montmorillonite desiccant will gradually increase with the use of time, and the effect of moisture absorption will also decrease. As the volume of the montmorillonite desiccant increases, it will move the movable push plate, the connecting plate and the movable cone block to the right, and then drive the movable ball, the movable rod and the chirping block to move upward in turn. The chirping block will fit and squeeze the filter frame to produce a chirping sound, which will be transmitted through the sound transmission tube to remind the staff that the montmorillonite desiccant needs to be replaced;

[0038] 3. The driving motor drives the movable shaft to rotate, and at the same time, the third bevel gear, the fourth bevel gear, the fan blade shaft and the fan blades are driven to rotate in sequence. When the fan blades rotate, wind force is generated, and the wind force floats to the inside of the limit frame through the air outlet pipe and the air collecting funnel, which can drive the ten wind blades to rotate with the wind force, and drive the fan blade rod, the speed regulating large gear, the speed changing small gear and the second reverse blade to generate strong suction force in sequence, and the particles and dust in the filter frame can be sucked into the inside of the dust box through the six dust suction heads and the dust inlet pipe for collection, so as to achieve the purpose of dust suction of the particles and dust in the filter frame;

[0039] 4. When the ten wind blades drive the fan blade rod to rotate, the movable blades will be driven to rotate to generate wind force, which will drive the wind plate and the adjustment plate to move left and right. When there are fewer particles on the inside of the filter frame, the wind force will be very strong, and the range of movement of the adjustment plate will also be very large. Through the elasticity of the spiral spring, the gap between the adjustment plate and the dust suction chamber will become smaller, and the suction force of the six dust suction heads will also become smaller. When there are more particles on the inside of the filter frame, the wind force will be very small, and the range of movement of the adjustment plate will be very small. Therefore, the gap between the adjustment plate and the dust suction chamber will become larger, and the suction force of the six dust suction heads will also become larger. The adsorption effect of the six dust suction heads can be controlled according to the number of particles inside the filter frame to enhance the adsorption effect of the six dust suction heads on the particles of the filter frame. The range and effect of the six dust suction heads on the adsorption of particles and dust on the filter frame can be increased by adjusting the adjustment mechanism, and the range and effect of the absorbent cotton board on the adsorption of moisture on the filter frame can be increased.

[0063] The implementation principle of a natural gas pipeline filter in the embodiment of the present application is:

[0064] (1) The purpose of natural gas flow transmission can be achieved through the cooperation between the air inlet pipe 75, the filter box 1 and the air outlet pipe 76. When the natural gas is transmitted, the filter frame 7 can filter and adsorb the particles and water in the natural gas to ensure the purity of the natural gas. The natural gas filtered by the filter frame 7 can be first concentrated by the gas collecting funnel 9 and blown onto the top of the power blades 12. The flow of natural gas can drive the ten power blades 12 to rotate, and then drive the power block 11, the support rod 10, the support round block 13, The power sheet 14 and the rubber belt 15 rotate in a circle, and can intermittently hit the sensor 16. By this method, the filter frame 7 can be detected. When there are many particles on the filter frame 7 and it is blocked, the natural gas flow rate will be slow, and then the ten power blades 12, the power block 11, the support rod 10, the support round block 13, the power sheet 14 and the rubber belt 15 will rotate very slowly due to the influence of the natural gas flow rate. The frequency of the rubber belt 15 hitting the sensor 16 is also very slow, and the signal will be transmitted to the motor 3 to drive and switch the two filter frames 7;

[0065] (2) The motor 3 can sequentially drive the drive shaft 4 and the two power gears 5 to rotate. When the two power gears 5 rotate, the two filter frames 7 can be moved and switched through the meshing relationship with the four transmission racks 6. The blocked filter frame 7 can be moved to the right side of the partition plate 17 for cleaning. At the same time, the cleaned filter frame 7 can be moved to the left side of the partition plate 17 to continue filtering the natural gas. It is not necessary to stop the transmission of natural gas to clean the filter frame 7, thereby ensuring the effect of natural gas transmission.

[0066] (3) When the two filter frames 7 are switched, the sensor 16 will also transmit signals to the bidirectional motor 19, the drive motor 29 and the two electric push rods 27 for driving. The bottom electric push rod 27 can sequentially drive the drying box 28, the absorbent cotton board 33, the air outlet pipe 46 and the detection box 50 to move up and down, so that the drying box 28, the absorbent cotton board 33, the air outlet pipe 46 and the detection box 50 can all fit with the bottom of the filter frame 7. The top electric push rod 27 can sequentially drive the dust collection box 47, the adjustment box 62, the dust collection box 48, the air collection funnel 64 and the six dust collection heads 60 to move up and down, so that the air collection funnel 64 and the six dust collection heads 60 can all fit with the top of the filter frame 7. The air collection funnel 64 will correspond to the air outlet pipe 46, and the six dust collection heads 60 will be located on the right side of the top of the drying box 28;

[0067] (4) The absorbent cotton board 33 fits the filter frame 7 to absorb the moisture on the filter frame 7. The driving motor 29 can drive the movable shaft 30 and the first reverse blade 31 to rotate in turn. When the first reverse blade 31 rotates, suction will be generated, which can speed up the speed of the absorbent cotton board 33 adsorbing the filter frame 7. At the same time, when the absorbent cotton board 33 absorbs moisture from the filter frame 7, the montmorillonite desiccant 61 inside the two storage boxes 32 can dry the absorbent cotton board 33. The suction force of the rotation of the first reverse blade 31 can speed up the drying speed of the montmorillonite desiccant 61 on the absorbent cotton board 33, which can further enhance the speed and effect of the absorbent cotton board 33 adsorbing moisture from the filter frame 7.

[0068] (5) As the montmorillonite desiccant 61 is used for a long time, its volume will gradually increase while absorbing moisture from the absorbent cotton board 33, and the effect of moisture absorption will also decrease. Because the top of the storage box 32 is restricted by the absorbent cotton board 33, the montmorillonite desiccant 61 will push the movable push plate 34 while its volume increases, so that the telescopic spring 41 is in a compressed state, which can drive the movable push plate 34, the connecting plate 35 and the movable cone block 36 to move to the right in turn. The inclined surfaces of the blocks 36 fit together, so when the movable cone block 36 moves to the right, it will push the movable ball 37, and then will drive the movable ball 37, the movable rod 38 and the chirping block 39 to move upward in turn, and the chirping block 39 can be gradually moved out of the storage slot, and the chirping block 39 will fit and squeeze the filter frame 7 to produce a chirping sound, which will be transmitted through the sound transmission tube 77, which can remind the staff that the montmorillonite desiccant 61 needs to be replaced to ensure the effect of the montmorillonite desiccant 61 on drying the absorbent cotton board 33;

[0069] (6) When the driving motor 29 drives the movable shaft 30 to rotate, it will also drive the third bevel gear 42, the fourth bevel gear 43, the fan shaft 44 and the fan blade 45 to rotate in sequence to generate wind force. Because the air outlet pipe 46 corresponds to the wind collecting funnel 64, the wind force will float to the inner side of the limit frame 63 through the air outlet pipe 46 and the wind collecting funnel 64. Because the wind blades 68 are located at the opening at the top of the wind collecting funnel 64, the wind collecting funnel 64 will concentrate the wind force and blow it on the ten wind blades 68, which can drive the ten wind blades 68 to rotate with the wind force. When the ten wind blades 68 rotate, they will drive the wind block 67, the fan blade rod 65, the speed regulating large gear 51, the speed changing small gear 52, and the connecting rod 5 3. The first gear 54, the transmission gear 55, the second gear 56, the connecting shaft 57 and the second reverse blade 58 rotate to generate a strong suction force, and the particles and dust in the filter frame 7 can be sucked into the inner side of the dust box 48 through the six dust suction heads 60, the connecting pipe 59, the dust suction chamber and the dust inlet pipe 49 in turn for collection. The speed-adjusting large gear 51 drives the speed-changing small gear 52 to rotate, and the connecting rod 53 and the second reverse blade 58 can be accelerated and accelerated, so that the fan blade rod 65 can ensure the speed of the second reverse blade 58 even when rotating at a low speed. The fan blade rod 65 rotates the second reverse blade 58 at a low speed to ensure a high speed suction force, and the rotation suction force of the second reverse blade 58 will not be affected by the large number of particles on the filter frame 7.

[0070] (7) The ten wind blades 68 drive the blade rod 65 to rotate, and at the same time drive the movable blades 66 to rotate to generate wind force. The wind force can be concentrated on the wind plate 70 by connecting the funnel 69. The spiral spring 72 can be compressed, and then the wind plate 70 and the adjustment plate 71 can be driven to move left and right in turn. The gap between the adjustment plate 71 and the dust suction chamber inside the dust suction box 47 can be adjusted to control the suction force inside the dust suction chamber. The wind force in the air outlet pipe 46 can be blown into the inner side of the wind collecting funnel 64 through the filter holes in the filter frame 7. When the filter frame 7 is When there are more particles on the side, the speed at which the wind drifts into the wind collecting funnel 64 is relatively slow, so the rotation speed of the ten wind blades 68, the wind block 67, the fan blade rod 65 and the movable blade 66 will also be relatively slow, and then the wind force of the movable blade 66 is not enough to blow the wind plate 70 and the adjustment plate 71 to move in a multi-range, and then the elasticity of the spiral spring 72 can control the current position of the adjustment plate 71. When there are fewer particles on the inner side of the filter frame 7, the speed at which the wind drifts into the wind collecting funnel 64 is relatively fast, so the ten wind blades 68 The speed at which the wind block 67, the fan blade rod 65 and the movable blade 66 rotate will also be relatively fast, and the rotating wind force of the movable blade 66 can blow the wind plate 70 and the adjustment plate 71 to move in a multi-range, and the wind force transmitted to the air collecting funnel 64 through the air outlet pipe 46 and the elasticity of the spiral spring 72 can control the position of the adjustment plate 71, adjust the gap size of the dust suction chamber in the dust suction box 47, and adjust the suction force inside the dust suction chamber. Because the six dust suction heads 60 and the drying box 28 are staggered and corresponding to each other, the suction forces of the two will not cause any interference. When the filter frame 7 is When there are fewer particles on the side, the wind force will be very strong, and the moving range of the adjustment plate 71 will also be very large, so the gap between the adjustment plate 71 and the dust suction chamber will become smaller, and then the suction force of the six dust suction heads 60 will also become smaller. When there are more particles inside the filter frame 7, the wind force will be very small, so the moving range of the adjustment plate 71 will also be very small, so the gap between the adjustment plate 71 and the dust suction chamber will become larger, and then the suction force of the six dust suction heads 60 will also become larger. The adsorption effect of the six dust suction heads 60 can be controlled according to the number of particles inside the filter frame 7, and the adsorption effect of the six dust suction heads 60 on the particles of the filter frame 7 can be enhanced;

[0071] (8) The two power rods 20, the two first bevel gears 21, the two second bevel gears 22 and the two threaded rods 23 can be driven to rotate respectively by the bidirectional motor 19, thereby driving the two threaded blocks 24, the two limit blocks 25, the two support plates 26 and the two electric push rods 27 to move left and right respectively. When the top electric push rod 27 moves left and right, it will drive the dust box 47, the air collecting funnel 64 and the six dust heads 60 to move left and right above the filter frame 7 in turn, which can improve the range and effect of the six dust heads 60 on the adsorption of particles and dust on the filter frame 7. When the bottom electric push rod 27 moves left and right, it will drive the drying box 28, the absorbent cotton board 33, the air outlet pipe 46 and the detection box 50 to move left and right below the filter frame 7 in turn, which can improve the range and effect of the absorbent cotton board 33 on the adsorption of moisture on the filter frame 7.

[0072] (9) Opening the sealing door 80 and the movable door 73 can clean the particles and dust in the dust box 48. Rotating the two movable handles 83 can respectively drive the two movable screws 82 to rotate, which can respectively drive the two rolling blocks 84 and the two movable clamping blocks 85 to move in opposite directions, so that the two movable clamping blocks 85 are separated from the absorbent cotton board 33. The absorbent cotton board 33 can be disassembled and the montmorillonite desiccant 61 in the two storage boxes 32 can be replaced to ensure the montmorillonite desiccant 61 has a drying effect on the absorbent cotton board 33.

[0073] Embodiment 2:

[0074] The present application also discloses a method for using a natural gas pipeline filter, based on the natural gas pipeline filter of embodiment 1, comprising the following steps:

[0075] S1. When natural gas flows and transmits through the air inlet pipe 75, the filter box 1 and the air outlet pipe 76, the filter frame 7 can filter and absorb particles and water in the natural gas. When the natural gas flows, it can drive the ten power blades 12 to rotate, and can drive the rubber belt 15 to rotate in a circle to intermittently hit the sensor 16 to detect the filter frame 7. When there are many particles on the filter frame 7, the natural gas flow speed will be slower, and the frequency of the rubber belt 15 hitting the sensor 16 will also be slow, which will transmit the signal to the motor 3 to drive the drive shaft 4 and the two power gears 5 to rotate, and can drive the two filter frames 7 to switch left and right, and move the cleaned filter frame 7 to the left side of the partition plate 17 to continue filtering the natural gas;

[0076] S2. The bottom electric push rod 27 can drive the water-absorbing cotton board 33 to move up and down to fit the bottom of the filter frame 7. The top electric push rod 27 can drive the six dust collector heads 60 to move up and down to fit the top of the filter frame 7. The water-absorbing cotton board 33 can absorb the moisture on the filter frame 7. The driving motor 29 drives the first reverse blade 31 to rotate to generate suction, thereby accelerating the speed at which the water-absorbing cotton board 33 absorbs moisture from the filter frame 7. When the water-absorbing cotton board 33 absorbs moisture, the montmorillonite desiccant 61 can dry the water-absorbing cotton board 33. The suction force of the rotation of the first reverse blade 31 accelerates the speed at which the montmorillonite desiccant 61 dries the water-absorbing cotton board 33.

[0077] S3. As the montmorillonite desiccant 61 is used for a long time, its volume will gradually increase when it absorbs moisture from the absorbent cotton board 33, and its moisture absorption will also decrease. When the volume of the montmorillonite desiccant 61 increases, it will drive the movable cone block 36 to move rightward, and will drive the movable ball 37 and the chirping block 39 to move upward, and squeeze with the filter frame 7 to produce a chirping sound, which will be transmitted through the sound transmission tube 77 to remind the user that the montmorillonite desiccant 61 needs to be replaced;

[0078] S4. The fan blades 45 are driven by the motor 29 to rotate to generate wind force, which can drive the ten wind blades 68 to rotate, and then drive the second reverse blade 58 to rotate. When the second reverse blade 58 rotates, it will generate a strong suction force, and the particles and dust in the filter frame 7 can be sucked into the inner side of the dust box 48 through the six dust suction heads 60 and the dust inlet pipe 49 for collection;

[0079] S5. The ten wind blades 68 can also drive the movable blades 66 to rotate to generate wind to blow on the wind plate 70, and the spiral spring 72 can be compressed to drive the adjustment plate 71 to move left and right to adjust the gap size of the dust suction chamber. When there are many particles in the filter frame 7, the speed at which the wind blows into the wind collecting funnel 64 is relatively slow, and the speed of the movable blades 66 rotating is also slow, which is not enough to blow the adjustment plate 71 to move in a wide range. When there are few particles inside the filter frame 7, the speed at which the wind blows into the wind collecting funnel 64 is relatively fast, and the speed of the movable blades 66 rotating is also fast, and then the movable blades 66 can blow the adjustment plate 71 to move in a wide range, and the adsorption effect of the six dust suction heads 60 can be controlled according to the number of particles inside the filter frame 7;

[0080] S6. The two threaded rods 23 can be driven to rotate by the bidirectional motor 19, thereby driving the two electric push rods 27 to move left and right. When the top electric push rod 27 moves left and right, it can drive the six vacuum heads 60 to move left and right on the filter frame 7, thereby increasing the range of the six vacuum heads 60 adsorbing particles and dust on the filter frame 7. When the bottom electric push rod 27 moves left and right, it can drive the absorbent cotton board 33 to move left and right under the filter frame 7, thereby increasing the range of the absorbent cotton board 33 adsorbing moisture on the filter frame 7, thereby ensuring the effect of the filter frame 7 on the adsorption and filtration of natural gas.

[0081] Compared with the prior art, the purpose of automatic cleaning of filter particles is achieved, there is no need to suspend the transportation of natural gas by the natural gas pipeline, and there is no need to frequently disassemble and clean the pipeline filter.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.

9. A method for using a natural gas pipeline filter, based on the natural gas pipeline filter according to claim 8, characterized in that: The following steps are involved: S1. When the natural gas flows through the inlet pipe (75), the filter box (1) and the outlet pipe (76), the filter frame (7) can filter and absorb particles and water in the natural gas. When the natural gas flows, it can drive the ten power blades (12) to rotate, and can drive the rubber belt (15) to rotate in a circular manner to intermittently hit the sensor (16) to detect the filter frame (7). When there are many particles on the filter frame (7), the natural gas flow speed will be slower, and the frequency of the rubber belt (15) hitting the sensor (16) will also be slower, which will transmit the signal to the motor (3) to drive the drive shaft (4) and the two power gears (5) to rotate, and can drive the two filter frames (7) to switch left and right, and move the cleaned filter frame (7) to the left side of the partition plate (17) to continue filtering the natural gas; S2.

The water-absorbing cotton plate (33) can absorb moisture on the filter frame (7), and the driving motor (29) drives the first reverse blade (31) to rotate to generate suction, thereby accelerating the speed at which the water-absorbing cotton plate (33) absorbs moisture from the filter frame (7). When the water-absorbing cotton plate (33) absorbs moisture, the montmorillonite desiccant (61) can dry the water-absorbing cotton plate (33), and the suction force generated by the rotation of the first reverse blade (31) accelerates the speed at which the montmorillonite desiccant (61) dries the water-absorbing cotton plate (33); S3. As the montmorillonite desiccant (61) is used for a long time, its volume will gradually increase when it absorbs moisture from the absorbent cotton board (33), and its moisture absorption will also decrease. When the volume of the montmorillonite desiccant (61) increases, it will drive the movable cone block (36) to move to the right, and will drive the movable ball (37) and the chirping block (39) to move upward, and squeeze with the filter frame (7) to produce a chirping sound. The chirping sound will be transmitted through the sound transmission tube (77), which can remind the user that the montmorillonite desiccant (61) needs to be replaced; S4. The fan blades (45) of the driving motor (29) rotate to generate wind force, and the wind force can drive the ten wind blades (68) to rotate, and then drive the second reverse blades (58) to rotate. When the second reverse blades (58) rotate, a strong suction force is generated, and particles and dust in the filter frame (7) can be sucked into the inner side of the dust collection box (48) through the six dust suction heads (60) and the dust inlet pipe (49) for collection; S5. The ten wind blades (68) can also drive the movable blades (66) to rotate and generate wind to blow on the wind plate (70), which can compress the spiral spring (72) and drive the adjustment plate (71) to move left and right to adjust the gap size of the dust suction chamber. When there are many particles in the filter frame (7), the speed at which the wind blows into the wind collecting funnel (64) is relatively slow, and the speed at which the movable blades (66) rotate is also slow, which is not enough to blow the adjustment plate (71) to move over a wide range. When there are few particles inside the filter frame (7), the speed at which the wind blows into the wind collecting funnel (64) is relatively fast, and the speed at which the movable blades (66) rotate is also fast, so that the movable blades (66) can blow the adjustment plate (71) to move over a wide range, and the adsorption effect of the six dust suction heads (60) can be controlled according to the number of particles inside the filter frame (7); S6. The two threaded rods (23) can be driven to rotate by the bidirectional motor (19), thereby driving the two electric push rods (27) to move left and right. When the top electric push rod (27) moves left and right, it can drive the six dust collector heads (60) to move left and right on the filter frame (7), thereby increasing the range of the six dust collector heads (60) adsorbing particles and dust on the filter frame (7). When the bottom electric push rod (27) moves left and right, it can drive the absorbent cotton plate (33) to move left and right below the filter frame (7), thereby increasing the range of the absorbent cotton plate (33) adsorbing moisture on the filter frame (7), thereby ensuring the effect of the filter frame (7) on the adsorption and filtration of natural gas.
