The vertical rod 7 is also connected to the connecting frame 42 by rotation through the rotating rod 44; the rectangular plate 8 is inserted into the rectangular groove 91 and fixed in the rectangular groove 91. When it is necessary to tilt the vertical rod 43 or the vertical rod 7, the No. 2 motor 83 is started, and the rotating shaft of the No. 2 motor 83 drives the round block 9 to rotate through the rectangular plate 8, and the round block 9 drives the vertical rod 43 or the vertical rod 7 to rotate through the rotating rod 44, so that the vertical rod 43 or the vertical rod 7 is tilted; at the same time, the winding and unwinding of the connecting rope 103 are coordinated to facilitate the vertical rod 43 or the vertical rod 7 to tilt or stand more stably; when the connecting frame 42 rotates, the supporting plate 81 can rotate and slide on the turntable 2 with the connecting frame 42. The No. 2 motor 83 is generally used in conjunction with the vertical rod 7 to assist some heavier filter membrane tubes 6 to tilt or stand with the vertical rod 7.

When the inside of the filter membrane tube 6 is cleaned, the turntable 2 rotates so that the vertical rod 43 is located at the connecting plate 1 23, the filter membrane tube 6 can be moved upward to perform the scraping operation. When the scraping operation inside the filter membrane tube 6 is completed, the turntable 2 is rotated again to make the vertical rod 43 located below the lifting shell 13; when the weather temperature is low, the electric telescopic rod 115 is started to make the lifting shell 13 drive the hollow rod 131 to move downward, so that the bottom end of the hollow rod 131 is lower than the top end of the vertical rod 43. When the moving ring 55 drives the filter membrane tube 6 to move upward so that the hollow rod 131 is located inside the filter membrane tube 6 (the inner wall of the filter membrane tube 6 and the outer wall of the hollow rod 131 are aligned with each other), the filter membrane tube 6 moves upward to the bottom end of the hollow rod 131. There is a gap), the external heater is started to allow the warm air to enter the lifting shell 13 through the air intake pipe. The air intake pipe adopts a rubber tube. When the warm air is discharged through the round hole on the hollow rod 131, the membrane liquid in the filter membrane tube 6 can be solidified faster; after the No. 3 motor 21 is started, the turntable 2 can be driven to rotate. The setting of the limit ring at the bottom of the turntable 2 and the annular groove at the top of the base 1 makes the turntable 2 more stable when rotating. After the No. 4 motor 41 is started, the connecting frame 42 can be driven to rotate, so that the connecting frame 42 drives the vertical rod 43 to rotate; the supporting frame 3 is located on the right side of the base 1 (such as. Figure 1 When the vertical rod 43 is tilted, the vertical rod 43 contacts the top of the support frame 31, and the support frame 31 is U-shaped, so that the staff can insert the filter membrane tube 6 into the vertical cylinder 56 for fixing.

[0017] like Fig.13 , Fig.14 and Fig.15As shown, a mobile unit 15 is fixed to the outer ring surface of the base 1, a support column 151 is fixed to the conveying surface of the mobile unit 15, a fixing ring 152 is fixed to the top of the support column 151, a group of through holes are opened on the fixing ring 152, an inflatable ring 153 is fixed in the through holes, a rubber ring 154 is fixed on the inner wall of the inflatable ring 153, a hose 155 connected to the inflatable ring 153 is fixed on the fixing ring 152, and two through holes respectively matched with the vertical rod 43 and the limit rod 4 are opened on the fixing ring 152; a collecting cylinder 16 is arranged above the mobile unit 15, the inner diameter of the collecting cylinder 16 is larger than the diameter of the fixing ring 152, and the axes of the two are Corresponding to the base 1, the collecting cylinder 16 has two slots 162 corresponding to the hose 155 and the support column 151 respectively on one side thereof, and a support leg 161 in contact with the ground is fixed on the collecting cylinder 16; a discharge port 163 is provided at the bottom of the collecting cylinder 16, a collecting shell 17 is fixed at the bottom of the collecting cylinder 16, the top of the collecting shell 17 is connected to the discharge port 163, and both sides of the interior of the collecting shell 17 are fixed with an inclined buffer plate 171; a hydraulic rod 14 corresponding to the collecting cylinder 16 is fixed on the base 1, a connecting rod 141 is fixed to the telescopic end of the hydraulic rod 14, and a bearing block 142 is fixed to the connecting rod 141. The mobile unit 15 is located at the front of the base 1 (with a discharge port 163 at the bottom of the collecting cylinder 16). Figure 1), when the turntable 2 rotates to make the filter membrane tube 6 pass through the lifting plate 113, the connecting plate 123 and the bottom of the lifting shell 13 in sequence to complete the scraping operation, the turntable 2 continues to rotate to make the filter membrane tube 6 correspond to the moving unit 15. The moving unit 15 is composed of a conveyor belt, a frame, a driver and two rotating shafts. After the driver drives one rotating shaft to rotate, the conveyor belt can start to rotate. The moving unit 15 belongs to the prior art and will not be described in detail here. When the scraping operation of the filter membrane tube 6 is completed, the vertical The rod 43 is tilted (the vertical rod 43 changes from a vertical position to a horizontal position, i.e., the vertical rod 43 rotates 90 degrees), and then the conveying surface of the mobile unit 15 drives the support column 151 to move so that the fixed ring 152 is close to the base 1, and then one end of the filter membrane tube 6 is inserted into the inner side of the rubber ring 154, and then the external air pump is started to inflate the inflatable ring 153 through the hose 155 (a group of inflatable rings 153 are connected by a pipeline, which is not shown in the figure, and one inflatable ring 153 is connected to the hose 155). After expansion, the rubber ring 154 can wrap and fix the filter membrane tube 6; then the mobile unit 15 drives the support column 151 away from the base 1, so that the fixing ring 152 enters the collecting tube 16, and the filter membrane tube 6 is pulled out from the vertical tube 56, so that the filter membrane tube 6 enters the collecting tube 16. When the filter membrane tube 6 completely enters the collecting tube 16, the air in the inflatable ring 153 is discharged, and then the fixing ring 152 continues to move, so that the filter membrane tube 6 is separated from the fixing ring 152 (it can also be manually assisted); then the filter membrane tube 6 enters the collecting shell 17 through the discharge port 163, and the buffer plate 171 in the collecting shell 17 can start the buffering effect during the process of the filter membrane tube 6 falling downward. The buffer plate 171 is made of rubber. Finally, the filter membrane tube 6 falls on the conveying surface of the mobile unit 15, so that the subsequent staff can collect it; at the same time, when the vertical rod 43 is in a horizontal state, the telescopic end of the hydraulic rod 14 drives the connecting rod 141 to rise, so that the bearing block 142 supports the vertical rod 43, thereby increasing the stability of the vertical rod 43.

When a group of filter membrane tubes 6 have completed film scraping, the telescopic end of the No. 3 automatic telescopic rod 184 drives the vertical plate 182 to move toward the turntable 2 through the control rod 185, so that the disc 18 is located below the film scraping head 125, and then the electric telescopic rod 115 drives the connecting plate 123 to move downward, and the film scraping head 125 moves downward into the cleaning cotton 186, so that the residual membrane liquid on the film scraping head 125 adheres to the cleaning cotton 186, so as to avoid excessive accumulation of membrane liquid on the film scraping head 125 affecting the subsequent film scraping processing of the filter membrane tube 6; then the No. 3 automatic telescopic rod 184 drives the vertical plate 182 to reset, and at the same time, the staff can start the No. 5 motor 183 to rotate the screw rod in the opening of the vertical plate 182, so that the mounting plate 181 moves downward, and drives the disc 18 to move downward, so that the staff can replace the cleaning cotton 186.

[0019] When in use, the vertical rod 43 is slowly tilted (the vertical rod 43 is rotated 90 degrees) to change the vertical rod 43 from a vertical state to a horizontal state. While the vertical rod 43 is tilted, the No. 1 motor 101 unwinds the connecting rope 103, and the staff inserts a group of filter membrane tubes 6 into a group of vertical cylinders 56 on the moving ring 55 for fixing, and then restores the vertical rod 43, and then uses the locking assembly to fix the vertical rod 43 in the connecting frame 42 to prevent the vertical rod 43 from tilting at will; then start the No. 3 motor 21 to rotate the turntable 2, so that the filter membrane tube 6 is located below the scraping assembly, and then start The second automatic telescopic rod 104 is moved to insert the insertion rod into the groove of the ring 45 to restrict the ring 45, and then the electric telescopic rod 115 is started to make the connecting plate 123 drive the membrane liquid conducting tube 122 to move downward, and the folding tube 121 is stretched, so that the film scraping head 125 is located below the top of the vertical rod 43; then the fourth motor 41 is started to rotate the connecting frame 42, and the connecting frame 42 drives the vertical rod 43 to rotate, and the ring 45 does not rotate at this time, and the auxiliary moving ring 55 moves upward, so that the filter membrane tube 6 moves upward, and the film scraping head 125 enters the filter membrane tube 6 When the bottom of the scraper head 125 is flush with the bottom of the filter membrane tube 6, the automatic switch valve 12 is started, and the external delivery pump uniformly delivers the membrane liquid in the external membrane liquid storage tank to the membrane liquid conducting tube 122. When the membrane liquid flows out from the bottom of the membrane liquid conducting tube 122, it falls on the scraper head 125, and then the vertical rod 43 is reversed, so that the moving ring 55 drives the filter membrane tube 6 to move downward slowly and uniformly, so that the membrane liquid that continues to flow to the scraper head 125 can be evenly coated on the inner wall of the filter membrane tube 6, completing the scraping operation on the inner wall of the filter membrane tube 6; the subsequent scraper head 125 is reset, the moving ring 55 drives the filter membrane tube 6 to recover, and then the turntable 2 continues to rotate, so that the filter membrane tube 6 is moved away from under the scraping assembly, the locking assembly is separated from the vertical rod 43, the insertion rod is separated from the groove on the ring 45, and then the vertical rod 43 is slowly tilted. After the vertical rod 43 is in a horizontal state, the filter membrane tube 6 is removed; and a group of connecting frames 42 on the turntable 2 can be provided, so that as the turntable 2 rotates, when a group of filter membrane tubes 6 completes the scraping operation, the next group of filter membrane tubes 6 can be added in time, thereby improving the processing efficiency of the filter membrane tubes 6.
