DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] As mentioned in the background art, in view of the problem that the filter membrane and the filter screen in the prior art are installed separately, which results in the need to be taken out separately for cleaning and maintenance, which is quite troublesome, the utility model provides a flexible tubular membrane filtration device.

[0027] Example 1

[0028] Reference Figures 1 to 3 A flexible tubular membrane filter device comprises a filter membrane 1, wherein the top and bottom sides of the filter membrane 1 are respectively connected with a connection cover 2 and a connection ring 3;

[0029] The inner wall of the filter membrane 1 is fitted with a filter cartridge 4, which is used to filter large particles. A fixing ring 5 and a fixing seat 6 are respectively provided on the top and bottom sides of the filter cartridge 4.

[0030] The outer wall and top of the fixing ring 5 are in contact with the inner wall of the connecting cover 2, and the outer wall of the fixing seat 6 is in contact with the connecting ring 3;

[0031] The connecting cover 2 is provided with a screw 7 connected to the fixing ring 5, and the connecting ring 3 is provided with a screw 8 connected to the fixing seat 6, which are used to fix the connecting cover 2 on the fixing ring 5 and the connecting ring 3 on the fixing seat 6;

[0032] A threaded barrel 9 is provided at the bottom of the fixing seat 6, and the threaded barrel 9 is threadedly connected to the inside of the connecting barrel 10, and mounting rods 11 are provided on both sides of the connecting barrel 10 for fixing the fixing seat 6;

[0033] The mounting rods 11 on both sides are connected to the inner wall of the transmission pipe 12. A drain port 13 is provided at the bottom of the transmission pipe 12. A fixing cover 14 is fitted and connected to the top of the transmission pipe 12. The fixing cover 14 is provided with screws 15 connected to the transmission pipe 12.

[0034] The bottom of the fixed cover 14 passes through the connecting cover 2. When water enters the bottom of the connecting cover 2 through the fixed cover 14, it can be blocked by the fixed seat 6, so that the water is first filtered by the filter cartridge 4 and then filtered by the filter membrane 1, and can be discharged through the drain port 13 at the bottom of the transmission pipe 12.

[0035] In order to remove the fixed cover 14 without affecting the upper equipment, a hose 16 is connected to the top of the fixed cover 14. The upper equipment transfers water to the fixed cover 14 through the hose 16, so that when the fixed cover 14 is removed, the hose 16 can be moved to the side to squeeze it, so as to facilitate the removal of the filter membrane 1 and the filter cartridge 4.

[0036] A rotating drum 17 is arranged on the top of the connecting cover 2, and an anti-slip ring 18 is arranged on the outer wall of the rotating drum 17 to facilitate rotation.

[0037] An observation window 19 opposite to the filter membrane 1 is provided on the transmission tube 12 for easy observation.

[0038] Example 2

[0039] Reference Figure 1 to Figure 2 Mounting plates 20 are provided on both sides of the transmission pipe 12 for fixing the transmission pipe 12 .

[0040] The rest of the structure is the same as that of Example 1.

[0041] When cleaning is needed, remove screw three 15 to take off the fixing cover 14, and then rotate the anti-slip ring 18 to make the connecting cover 2 drive the fixing ring 5 to rotate, and then drive the fixing seat 6 to rotate through the filter cartridge 4, and then drive the threaded cylinder 9 to be removed from the connecting cylinder 10, so that the filter membrane 1 and the filter cartridge 4 can be removed from the transmission pipe 12 at the same time, which is more convenient. Remove the thick and then remove screw one 7 and screw two 8, and the filter cartridge 4 and the filter membrane 1 can be cleaned separately. The impurities in the filter membrane 1 during cleaning can be discharged from the connecting ring 3, and the impurities in the filter cartridge 4 can be discharged from the fixing ring 5.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
