Description

Technical Field

[0001] The present invention relates to a water treatment device, and particularly to a membrane filtration component unit. Background Art

[0002] Existing membrane filtration components generally include multiple membrane filtration component units. Each membrane filtration component unit includes a screw barrel, a water inlet end cover clamped to the bottom of the screw barrel, a water production end cover clamped to the top of the screw barrel, and a membrane filament bundle located inside the screw barrel. The water inlet end cover is provided with a water inlet and an air inlet, and the water production end cover is provided with a water production outlet and a concentrated water outlet. Among them, the membrane filaments at the water inlet end of the membrane filtration component unit are generally sealed by casting with a casting cover. The casting cover is provided with a conical convex shaft, and the conical convex shaft is inserted into the membrane filaments to form a casting hole, which is the water inlet hole in the final product. Since the conical convex shaft is inserted forcefully, it is easy to cause the membrane filaments at the casting hole, that is, the water inlet hole, to be messy and irregular after molding, resulting in poor water flow at the initial water inlet end of the entire membrane filtration unit; and during the cleaning process of the membrane filaments at the water inlet hole, it becomes an air inlet hole. Similarly, during the air scrubbing process, the messy and irregular shape of the membrane filaments at the air inlet hole will form a cavity accumulation effect, resulting in a weak scrubbing influence and a significant reduction in the membrane filament cleaning effect; during the backwashing and drainage process, the messy and irregular shape of the membrane filaments at the air inlet hole will also cause the cavities between the membrane filaments to be too narrow, resulting in poor drainage and difficulty in discharging large-particle dirt completely; in addition, in practical applications, such components mostly produce water under positive pressure and cannot achieve negative pressure suction water production or siphon water production, resulting in a relatively large energy consumption problem; finally, existing membrane filtration component units generally adopt a common lateral outlet structure and can only be arranged in a traditional frame type, and cannot achieve rapid assembly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a membrane filtration component unit. The technical solution it adopts is: a membrane filtration component unit, which includes a screw barrel, a water inlet end cover clamped to the bottom of the screw barrel, a water production end cover clamped to the top of the screw barrel, and a membrane filament bundle located inside the screw barrel. The water inlet end cover is provided with a water inlet and an air inlet, and the water production end cover is provided with a water production outlet and a concentrated water outlet. The characteristics are that: a cap is arranged at the end of each membrane filament bundle inside the screw barrel, and the end of the membrane filament bundle and the cap are bonded together by resin casting. A PVC flower plate fixedly connected to the inner wall of the screw barrel is also arranged between the membrane filament bundle and the water inlet end cover. The PVC flower plate is provided with a cap hole for the cap to pass through, and air-water holes for ventilation and water distribution are also arranged in the middle of the PVC flower plate and around the cap hole of the PVC flower plate.

[0004] A further technical feature of the present invention is: Two symmetrically arranged water inlets are provided on the water inlet end cover, and two symmetrically arranged water production outlets are provided on the water production end cover.

[0005] An annular concave platform is arranged at the position corresponding to the inner wall of the screw barrel and the PVC faceplate, and the PVC faceplate and the annular concave platform are fixedly connected together by adhesive.

[0006] The outer wall of the cap and the inner wall of the cap hole on the PVC flower disc are fixedly connected together by adhesive.

[0007] The beneficial effects of the present invention are: Since a cap is provided at the end of each membrane bundle in the screw barrel described in the present invention, the end of the membrane bundle and the cap are bonded together by resin casting, a PVC flower disc fixedly connected to the inner wall of the screw barrel is also provided between the membrane bundle and the water inlet end cover, and the PVC flower disc is provided with a cap hole for the cap to pass through, and air and water holes for ventilation and water distribution are also provided in the middle of the PVC flower disc and around the PVC flower disc cap hole. In this way, the membrane filament bundle and the cap are cast together with resin in advance to complete the membrane filament sealing, and the membrane filament bundle is fixed by the cap hole on the PVC disc. The gaps between the membrane filament bundles and the air and water holes on the PVC disc will always remain unobstructed, thereby solving the problems of poor water inlet and water outlet of the existing membrane filtration component unit and poor air scrubbing effect; in addition, the water inlet end cover of the present invention is provided with two symmetrically arranged water inlet holes, and the water production end cover is provided with two symmetrically arranged water production outlets. This double-ear structure cooperates with the ferrule connection to achieve rapid assembly, and the concentrate outlet channel is emptied, so that the component is transformed into a water storage membrane pool, so that negative pressure suction water production can be achieved.
