Description

Technical Field

[0001] The utility model relates to a pouring device, belonging to the field of hollow fiber membrane processing equipment. Background Art

[0002] During the manufacturing process of the hollow fiber membrane curtain membrane assembly, a certain number of hollow fiber membrane filaments are first fixed into two neatly arranged membrane sheets using a clamp tube, and then evenly arranged in a casting trough. The guide orifice plate is then used to separate the membrane sheets from the middle of the casting trough, and then the trough body with the membrane filaments installed and the membrane filaments in this area are cast and sealed to form water inlet and outlet channels at the casting seal.

[0003] In the prior art, during the casting process of the hollow fiber membrane assembly, the liquid casting material needs to be transported and cast from top to bottom. Since the distance between the discharge port and the bottom of the inner wall of the mold groove is relatively far, bubbles are easily generated in the raw material inside the mold groove during the casting process, resulting in bubbles inside the molded hollow fiber membrane assembly, thereby reducing the casting processing quality of the hollow fiber membrane assembly.

[0004] In summary, the utility model provides a pouring device to solve the above problems. Utility Model Content

When the annular tube 11 moves downward, the two casting pipes 12 can be driven to move to the inside of the casting mold 5, and the discharge ports of the two casting pipes 12 at one end that are separated are close to the inner wall of the casting mold 5, so that the two casting pipes 12 can transport the hollow fiber membrane casting material to the inside of the casting mold 5, while the casting material can slide downward along the inner wall of the casting mold 5, thereby effectively avoiding bubbles generated during the casting process.

[0026] See also Figure 2-5 The lifting mechanism 9 includes two connecting plates 91 and a chassis 92. The two connecting plates 91 are fixedly connected to the bottom of the fixing plate 3 and are located above the annular tube 11. The chassis 92 is fixedly connected to the top of the fixing plate 3. A motor 94 is fixedly connected inside the chassis 92. The motor 94 is a three-phase asynchronous motor. The output end can be adjusted for forward and reverse rotation. The motor 94 is connected to an external power supply and is provided with a power control switch. A limiting plate 93 is fixedly connected between the bottoms of the two connecting plates 91. A screw rod 95 is fixedly connected to the output end of the motor 94. One end of the screw rod 95 passes through the chassis 92 and the fixing plate 3 in sequence and extends to the bottom of the fixing plate 3. A threaded sleeve 96 is sleeved between the rod surface and the bottom end of the screw rod 95 and is located directly above the annular tube 11. One end of the threaded sleeve 96 passes through the top of the limiting plate 93 and extends to the center of the inner ring of the annular tube 11. The bottom end of the threaded sleeve 96 and the inner ring surface of the annular tube 11 are fixedly connected with a circular plate 98.

[0027] See also Figure 2-5The screw rod 95 is rotatably connected to the chassis 92, the top edge of the threaded sleeve 96 is an outwardly convex ring, and the top of the threaded sleeve 96 has a limiting effect on the moving distance of the threaded sleeve 96, so that the threaded sleeve 96 and the limiting rod 97 will not be disconnected from the limiting plate 93, the screw rod 95 is rotatably connected to the fixed plate 3, the screw rod 95 is threadedly connected to the threaded sleeve 96, the threaded sleeve 96 is in contact with the limiting plate 93, the outer annular surface of the circular plate 98 is fixedly connected to the inner annular surface of the annular tube 11, and one side of the top of the circular plate 98 is fixedly connected A limiting rod 97 is connected, one end of which passes through the bottom of the limiting plate 93 and extends to the bottom of the fixed plate 3. The limiting rod 97 has a limiting effect on the limiting plate 93. The limiting rod 97 is in contact with the limiting plate 93, and one end of the limiting rod 97 is in contact with the bottom of the fixed plate 3. The limiting rod 97 and the limiting plate 93 have a limiting effect on the circular plate 98 and the threaded sleeve 96. When the screw rod 95 rotates forwards and backwards, the threaded sleeve 96 can be driven to move up and down, thereby driving the circular plate 98 to move up and down.

[0028] Specific implementation method: By starting the counterclockwise rotation switch at the output end of the motor 94 inside the lifting mechanism 9, the screw rod 95 can be driven to rotate counterclockwise. Since the limit rod 97 and the limit plate 93 have a limiting effect on the circular plate 98 and the threaded sleeve 96, the threaded sleeve 96 can slide downward on the limit plate 93, thereby driving the circular plate 98 to move downward. The circular plate 98 drives the annular tube 11 to move downward. The annular tube 11 drives one end of the corrugated telescopic tube 8 to move downward through the connecting tube 10 and stretches the corrugated telescopic tube 8. The annular tube 11 drives the two casting tubes 12 to move to the bottom of the inside of the casting mold 5, so that the two ends of the casting tube 12 are close to the bottom of the inner wall of the casting mold 5.

[0029] Start the glue pump 6, extract liquid raw materials from the glue inlet pipe 13 through the glue pump 6 and evenly transport the raw materials to the inside of the two casting pipes 12 through the glue outlet pipe 7, the corrugated expansion pipe 8, the connecting pipe 10 and the annular pipe 11. The separated ends of the two casting pipes 12 are tilted downward. When the annular pipe 11 moves downward, it can drive the two casting pipes 12 to move to the inside of the casting mold 5, and make the discharge ports of the separated ends of the two casting pipes 12 close to the inner wall of the casting mold 5, so that the two casting pipes 12 can transport the hollow fiber membrane casting material to the inside of the casting mold 5, and the casting material can slide downward along the inner wall of the casting mold 5, thereby effectively avoiding bubbles generated during the casting process, and effectively improving the casting processing quality of the hollow fiber membrane.

[0030] During the pouring process, the output end of the starter motor 94 is turned clockwise to drive the threaded sleeve 96 and the circular plate 98 to move upward, and then the annular tube 11 and the two pouring tubes 12 can be driven to move upward, thereby avoiding the phenomenon that the raw materials will contaminate the pouring equipment during the hollow fiber membrane pouring process, resulting in raw material residue and dripping on the surface of the processing device, and effectively improving the quality of the hollow fiber membrane pouring process environment.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
