[0023] The following will clearly and completely describe the technical solutions in the embodiments of this patent in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0024] Please refer to Figures 1-5 , this patent provides a technical solution:

[0025] In this technical solution, a static mixer that is convenient for disassembly and maintenance includes a mixer housing 1. An accommodation cavity is provided inside the mixer housing 1, and a spoiler rack tube 6 is assembled inside the accommodation cavity; spoiler blocks 2 are evenly assembled inside the spoiler rack tube 6. A limiting ring 3 is sleeved at the end of the mixer housing 1, and a bearing vertical tube 5 is sleeved outside the spoiler rack tube 6; a connecting plate is assembled between the bearing vertical tube 5 and the limiting ring 3; the bearing vertical tube 5 and the spoiler rack tube 6 are connected by a connecting structure 4. The connecting structure 4 includes a metal tube 401, a rubber ring 402, a clamping block 403, and an L-shaped groove 404;

[0026] Ear plates 7 are installed on both side walls of the spoiler block 2, and the ear plates 7 are arranged in contact with the inner wall of the spoiler rack tube 6; screw grooves 8 are provided on the side walls of the ear plates 7, and counterbore screw holes 10 are provided on the side wall of the spoiler rack tube 6 at the positions of the screw grooves 8. A fixing rod 9 is screwed in the counterbore screw holes 10 and the screw grooves 8;

[0027] In this technical solution, the spoiler rack tube 6 is installed inside the mixer housing 1. The spoiler blocks 2 are evenly installed at equal distances from the inside to the outside inside the spoiler rack tube 6. The limiting ring 3 is connected to the bearing vertical tube 5 through a connecting plate. After the bearing vertical tube 5 and the spoiler rack tube 6 are connected, the limiting ring 3 can be sleeved outside the mixer housing 1 to fix the two.

[0028] In some technical solutions, referring to Figures 1-5 , the metal tube 401 is connected to the spoiler rack tube 6, the rubber ring 402 is installed inside the bearing vertical tube 5, the clamping block 403 is installed on the outer wall of the metal tube 401, the L-shaped groove 404 is provided on the rubber ring 402, the L-shaped groove 404 is provided on the metal tube 401, the metal tube 401 is inserted into the rubber ring 402, and the clamping block 403 is clamped in the L-shaped groove 404; a groove 11 is provided on the clamping block 403, a spring 12 is installed in the groove 11, a ball 13 is installed on the spring 12, and an arc groove 14 is provided on the L-shaped groove 404. The ball 13 is clamped in the arc groove 14.

[0029] In this technical solution, the spoiler pipe 6 is inserted with the metal pipe 401 into the rubber ring 402 on the bearing vertical pipe 5, so that the spoiler pipe 6 is hermetically connected to the bearing vertical pipe 5. As the metal pipe 401 is inserted into the rubber ring 402 on the bearing vertical pipe 5, the clamping block 403 is clamped into the L-shaped groove 404. Then, when the metal pipe 401 is rotated, the clamping block 403 is clamped into the root position of the L-shaped groove 404. At this time, the spring 12 in the groove 11 gives the ball 13 a force towards the outside, and the ball 13 is clamped into the arc-shaped groove 14, enhancing the connection stability between the spoiler pipe 6 and the bearing vertical pipe 5. Conversely, the bearing vertical pipe 5 and the spoiler pipe 6 can be disassembled.

[0030] In some technical solutions, referring to FIGS. 1-5, an external thread 15 is provided on the outer wall of the fixing rod 9, and the external thread 15 is engaged with the internal threads of the countersunk screw hole 10 and the screw groove 8. A turntable 13 is installed at the end of the fixing rod 9, and the turntable 13 is arranged in the countersunk screw hole 10;

[0031] In this technical solution, when installing the spoiler block 2, the screw groove 8 in the ear plate 7 on the spoiler block 2 is aligned with the countersunk screw hole 10 in the spoiler pipe 6, and by means of threaded connection, the fixing screw 8 is screwed into the countersunk screw hole 10 and the screw groove 8, thereby fixing the spoiler block 2 inside the spoiler pipe 6.

[0032] In some technical solutions, referring to Figures 1-5 , anti-slip grooves 16 are evenly and equidistantly provided on the outer wall of the turntable 13 along its axis;

[0033] In this technical solution, through the arrangement of the anti-slip grooves 16, it is prevented that when the turntable 13 is rotated, a slipping phenomenon occurs.

[0034] In some technical solutions, referring to Figures 1-5 , slider blocks 18 are installed on the outer wall of the spoiler pipe 6 in a triangular shape, and sliding grooves are provided in a triangular shape on the inner wall of the mixer housing 1, and the slider blocks 18 are installed in the sliding grooves;

[0035] In this technical solution, the sliding of the slider blocks 18 in the sliding grooves facilitates the sliding of the spoiler pipe 6 in the mixer housing 1.

[0036] Working principle: When in use, when maintenance is required, first, through the connection structure 4, the bearing vertical pipe 5 is disconnected from the spoiler pipe 6. Then, the limit ring 3 and the bearing vertical pipe 6 are disengaged from the mixer housing 1. Then, the spoiler pipe 6 is taken out of the mixer housing 1, and the fixing rod 9 in the countersunk screw hole 10 is removed, and the spoiler block 2 can be taken out from the inside of the spoiler pipe 6 for maintenance. That's it.
