The nozzle is provided with nozzles distributed around the outside of the squeezing head for spraying water to soften the blockage mud, so that the water sprayed from the nozzle can soften the blockage mud.

[0016] Preferably, a connecting pipe is provided below the one-way pipe, and one end of the connecting pipe is fixedly connected to the upper side wall of the conveying pipe, and the other end of the connecting pipe is fixedly installed through the end face of the pressure control cylinder. A pressure plug is fitted to the side of the inner wall of the pressure control cylinder near the connecting pipe, and the rod of the pressure plug slides through the other side of the inner wall of the pressure control cylinder, so that the pressure plug can move inside the pressure control cylinder.

[0017] Preferably, a storage box is fixedly connected to the end face of the pressure control cylinder, and the storage box and the pressure control cylinder are fixedly connected to the top of the loading cylinder. The rod of the pressure plug rod slides through the storage box, and one end of the rod of the pressure plug rod is rotatably connected to a transmission rod. The other end of the transmission rod is rotatably connected to the edge of the rotating disk. The transmission rod is located inside the storage box, so that the transmission rod can drive the pressure plug rod to move inside the pressure control cylinder.

[0018] Preferably, the lower end of the connecting rod of the transmission gear is coaxially fixedly connected to the center of the upper surface of the rotating disk, and the transmission gear is rotatably mounted on the inner wall of the storage box. A meshing rack is horizontally arranged on the side of the transmission gear, and the rack slides through the storage box. The end of the rack is horizontally fixedly connected to the top of the grip frame, so that the transmission gear can drive the rotating disk to rotate.

[0019] Preferably, an inner plug is coaxially fixedly connected to the push rod in the middle of the gripping frame, and the push rod of the gripping frame slides through the suction cylinder. The inner plug is fitted against the inner wall of the suction cylinder and is located on the upper port side of the discharge tube. An abutment rod is fixedly connected to the bottom side wall of the gripping frame and slides through the support plate on the loading cylinder. The end face of the abutment rod is fitted against the plug of the push rod. The plug of the push rod is fitted against the inner side of the discharge cylinder. A thrust spring for providing thrust is fixedly connected between the side of the push rod away from the abutment rod and the inner wall of the discharge cylinder, so that the push rod can move inside the discharge cylinder.

[0020] The operating method for unblocking tools is as follows:

[0021] S1: The inlet pipe is connected to the drain pipe of the external water pump equipment. When the device needs to adapt to the cleaning length of different tubular ultrafiltration membranes, first rotate the screw so that the screw drives the lower pressure frame away from the bottom of the outer tube. Then pull up the pull rod so that the pull rod drives the upper pressure frame to move upward a certain distance and further compress the fastening spring. At this time, the limit block at the bottom of the upper pressure frame will move away from the positioning hole on the outer tube, so that the outer tube can be extended from the receiving tube. The outer tube drives the inner core tube to move synchronously through the inner end tube and the inner support frame. Then release the pull rod so that the limit block can enter the corresponding positioning hole. Then drive the lower pressure frame to reset through the screw.

[0022] S2: Next, the outer tube is horizontally inserted into the internally clogged tubular ultrafiltration membrane, so that the extrusion head can press tightly against the clogged sludge inside the tubular ultrafiltration membrane. The external water pump sends water into the one-way tube through the inlet pipe. The sealing block drives the control frame to move downwards, further compressing the pressure spring. At this time, the water in the one-way tube can enter the inner core tube through the delivery pipe, and the water in the inner core tube will flow into the inner end tube through the rubber tube. The water in the inner end tube is sprayed through the nozzle onto the sludge that contacts the extrusion head for softening treatment.

[0023] S3: During the above process, the user pulls the grip frame back and forth simultaneously. At this time, the grip frame will drive the rack, the abutment rod and the inner plug to move synchronously. The moving rack will drive the transmission gear to rotate synchronously. The transmission gear will drive the rotating disk connected to the bottom to rotate synchronously. The rotating disk will drive the pressure plug rod to move synchronously through the transmission rod. When the pressure plug rod moves away from the near delivery pipe, the pressure control cylinder will generate negative pressure, thereby drawing water into the delivery pipe. When the pressure plug rod moves closer to the near delivery pipe, the water in the pressure control cylinder will be forced into the delivery pipe, thereby effectively increasing the water pressure in the delivery pipe. This causes the water pressure sent into the inner core tube by the delivery pipe to change continuously. At this time, the rubber tube between the inner core tube and the inner end tube will periodically expand and contract to prevent the outer tube end of the rubber tube from being blocked by mud and water. At the same time, the nozzle on the side wall of the inner end tube can also spray out cleaning water.

[0024] S4: When the gripping frame moves the contact rod away from the pusher rod, the compressed thrust spring will push the pusher rod to move through the reset action, so that the plug of the pusher rod can block the lower end of the feed pipe. At this time, the gripping frame continues to move the inner plug in the suction cylinder. At this time, a negative pressure will be generated in the suction cylinder. At this time, the mud and water cleaned out at the extrusion head will flow into the bottom of the inner wall of the suction cylinder through the outer pipe.

[0025] S5: When the gripping frame moves the abutment rod and inner plug to reset, the abutment rod can move the pusher rod to compress the push spring. At this time, the plug at the bottom of the pusher rod no longer blocks the lower end of the discharge pipe. At the same time, the inner plug can push the mud and water in the suction cylinder into the discharge pipe, and the mud and water in the discharge pipe can be discharged through the discharge cylinder.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: This tubular ultrafiltration membrane clogging and unclogging tool and its method of use are equipped with a double-layer cleaning head. While the cleaning head sprays water to soften the clogging sludge, it can also simultaneously extract the mud and water from the tubular ultrafiltration membrane through a suction structure, thereby improving the cleaning effect of the device. The specific details are as follows:

[0027] 1. The outer tube has a conical structure at the end near the inner tube. Mesh holes are provided on the conical end face of the outer tube. The middle of the inner tube is fixedly connected to a nozzle with equal angle distribution. The nozzles are inclined and the outer port of the nozzles faces the mesh holes on the outer tube. The end of the inner tube away from the outer tube is fixedly connected to the liquid inlet of the nozzle. A squeezing head is fixedly connected to the inner wall of the nozzle, and the nozzle has nozzles distributed around the outside of the squeezing head. This allows the water in the inner tube to be sprayed out through the nozzle to soften and clean the mud. At the same time, the outer tube can extract the mud and water produced.

[0028] 2. An inner plug is coaxially fixedly connected to the push rod in the middle of the gripping frame. The push rod of the gripping frame slides through the suction cylinder. The inner plug is fitted against the inner wall of the suction cylinder. The inner plug is located on the side of the upper end of the discharge pipe. An abutment rod is fixedly connected to the bottom side wall of the gripping frame. The end face of the abutment rod is fitted against the plug of the push rod. A thrust spring is fixedly connected between the push rod and the inner wall of the discharge cylinder. The gripping frame drives the abutment rod away from the push rod. At this time, the push spring will push the push rod to close the discharge pipe end through the reset action, so that the inner plug can generate negative pressure to suck mud and water in the suction cylinder.

When the gripping frame 27 moves the abutment rod 29 away from the push rod 2803, the push spring 2804 will push the push rod 2803 to move through the reset action.

[0052] The operating method for unblocking tools is as follows:

[0053] S1: The inlet pipe 15 is connected to the drain pipe of the external water pump equipment. When the device needs to adapt to the cleaning length of different tubular ultrafiltration membranes, first rotate the screw 507 so that the screw 507 drives the lower pressure frame 505 away from the bottom of the outer tube 3, then pull up the pull rod 504 so that the pull rod 504 drives the upper pressure frame 501 to move upward a certain distance and further compress the fastening spring 503. At this time, the limiting block 502 at the bottom of the upper pressure frame 501 will move away from the positioning hole 4 on the outer tube 3, so that the outer tube 3 can be extended from the receiving tube 2. The outer tube 3 drives the inner core tube 12 to move synchronously through the inner end tube 6 and the inner support frame 11. Then release the pull rod 504 so that the limiting block 502 can enter the corresponding positioning hole 4, and then drive the lower pressure frame 505 to reset through the screw 507.

[0054] S2: Next, the outer tube 3 is horizontally inserted into the internally clogged tubular ultrafiltration membrane, so that the extrusion head 8 can press tightly against the clogged sludge inside the tubular ultrafiltration membrane. The external water pump sends water into the one-way tube 14 through the inlet pipe 15. The sealing block 16 drives the control frame 17 to move downward, further compressing the pressure spring 18. At this time, the water in the one-way tube 14 can enter the inner core tube 12 through the delivery pipe 13. The water in the inner core tube 12 will flow into the inner end tube 6 through the rubber tube 10. The water in the inner end tube 6 is sprayed through the nozzle 7 onto the sludge that contacts the extrusion head 8 for softening treatment.

[0055] S3: During the above process, the user simultaneously pulls the grip frame 27 back and forth. At this time, the grip frame 27 will drive the rack 26, the contact rod 29, and the inner plug 31 to move synchronously. The moving rack 26 will drive the transmission gear 25 to rotate synchronously. The transmission gear 25 will drive the rotating disk 23 connected to the bottom to rotate synchronously. The rotating disk 23 will drive the pressure plug rod 21 to move synchronously through the transmission rod 22. When the pressure plug rod 21 moves away from the near-conveying pipe 13, the pressure control cylinder 20 will generate negative pressure, thereby controlling the conveying... Water is drawn into pipe 13. When pressure plug 21 approaches the delivery pipe 13, the water in pressure control cylinder 20 will be forced into the delivery pipe 13, thereby effectively increasing the water pressure in the delivery pipe 13. This causes the water pressure sent into the inner core pipe 12 by the delivery pipe 13 to change continuously. At this time, the rubber tube 10 between the inner core pipe 12 and the inner end pipe 6 will periodically expand and contract to prevent the end of the outer pipe 3 outside the rubber tube 10 from being blocked by mud and water. At the same time, the nozzle 9 on the side wall of the inner end pipe 6 can also spray out cleaning water.

[0056] S4: When the gripping frame 27 drives the contact rod 29 away from the pusher rod 2803, the compressed thrust spring 2804 will push the pusher rod 2803 to move through the reset action, so that the plug of the pusher rod 2803 can block the lower end of the feed pipe 2802. At this time, the gripping frame 27 continues to drive the inner plug 31 to move in the suction cylinder 30. At this time, a negative pressure will be generated in the suction cylinder 30. At this time, the mud and water cleaned out at the extrusion head 8 will flow into the bottom of the inner wall of the suction cylinder 30 through the outer pipe 3.

[0057] S5: When the gripping frame 27 drives the abutment rod 29 and the inner plug 31 to reset, the abutment rod 29 can drive the pusher rod 2803 to move and compress the push spring 2804. At this time, the plug at the bottom of the pusher rod 2803 no longer blocks the lower end of the feed pipe 2802. At the same time, the inner plug 31 can push the mud and water in the suction cylinder 30 into the feed pipe 2802, and the mud and water in the feed pipe 2802 can be discharged through the discharge cylinder 2801.

10. The method of using the clogging and unclogging tool for a tubular ultrafiltration membrane according to claim 1, characterized in that: The operating method for unblocking tools is as follows: S1: The inlet pipe (15) is connected to the drain pipe of the external water pump equipment. When the device needs to adapt to the cleaning length of different tubular ultrafiltration membranes, first rotate the screw (507) so that the screw (507) drives the lower pressure frame (505) away from the bottom of the outer tube (3), then pull up the pull rod (504) so ​​that the pull rod (504) drives the upper pressure frame (501) to move upward a certain distance to further compress the fastening spring (503). At this time, the limiting block (502) at the bottom of the upper pressure frame (501) will move away from the positioning hole (4) on the outer tube (3), so that the outer tube (3) can be extended from the storage tube (2). The outer tube (3) drives the inner core tube (12) to move synchronously through the inner end tube (6) and the inner support frame (11). Then release the pull rod (504) so ​​that the limiting block (502) can enter the corresponding positioning hole (4), and then drive the lower pressure frame (505) to reset through the screw (507). S2: Next, the outer tube (3) is horizontally inserted into the tubular ultrafiltration membrane that is blocked inside, so that the extrusion head (8) can press tightly against the blockage sludge in the tubular ultrafiltration membrane. The external water pump sends water into the one-way tube (14) through the inlet pipe (15). The sealing block (16) drives the control frame (17) to move downward to further compress the pressure spring (18). At this time, the water in the one-way tube (14) can enter the inner core tube (12) through the delivery pipe (13), and the water in the inner core tube (12) will flow into the inner end tube (6) through the rubber tube (10). The water in the inner end tube (6) is sprayed through the nozzle (7) onto the sludge that contacts the extrusion head (8) for softening treatment. S3: During the above process, the user pulls the grip (27) back and forth synchronously. At this time, the grip (27) will drive the rack (26), the contact rod (29) and the inner plug (31) to move synchronously. The moving rack (26) will drive the transmission gear (25) to rotate synchronously. The transmission gear (25) will drive the rotating disk (23) connected to the bottom to rotate synchronously. The rotating disk (23) will drive the pressure plug rod (21) to move synchronously through the transmission rod (22). When the pressure plug rod (21) moves away from the near delivery pipe (13), the pressure control cylinder (20) will generate negative pressure, thereby controlling the delivery. Water is pumped into the pipe (13). When the pressure plug (21) approaches the delivery pipe (13), the water in the pressure control cylinder (20) will be forced into the delivery pipe (13), thereby effectively increasing the water pressure in the delivery pipe (13). This causes the water pressure sent into the inner core pipe (12) by the delivery pipe (13) to change continuously. At this time, the rubber tube (10) between the inner core pipe (12) and the inner end pipe (6) will periodically expand and contract to prevent the outer end of the outer pipe (3) outside the rubber tube (10) from being blocked by mud and water. Meanwhile, the nozzle (9) on the side wall of the inner end pipe (6) can also spray out cleaning water. S4: When the gripper (27) drives the contact rod (29) away from the pusher rod (2803), the compression spring (2804) will push the pusher rod (2803) to move through the reset action, so that the plug of the pusher rod (2803) can block the lower end of the feed pipe (2802). At this time, the gripper (27) continues to drive the inner plug (31) to move in the suction cylinder (30). At this time, a negative pressure will be generated in the suction cylinder (30). At this time, the mud and water cleaned out at the extrusion head (8) will flow into the bottom of the inner wall of the suction cylinder (30) through the outer pipe (3). S5: When the gripping frame (27) drives the abutment rod (29) and the inner plug (31) to reset, the abutment rod (29) can drive the pusher rod (2803) to move and compress the push spring (2804). At this time, the plug at the bottom of the pusher rod (2803) no longer blocks the lower end of the feed pipe (2802). Meanwhile, the inner plug (31) can push the mud and water in the suction cylinder (30) into the feed pipe (2802), and the mud and water in the feed pipe (2802) can be discharged through the discharge cylinder (2801).
