DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-5 In the embodiments of the utility model, an efficient static mixer comprises a pipeline 1 connected with a feeding device, a mixed core 2 is detachably connected inside the pipeline 1, the central axis of the mixed core 2 is a tubular structure, one end of the pipeline 1 is provided with a discharge pipe 3, both ends of the pipeline 1 are detachably connected with connecting pieces 4 for fixing the mixed core 2, the inside of the discharge pipe 3 is provided with an accelerating piece 5 in communication with the inside of the central axis of the mixed core 2, the accelerating piece 5 comprises a connecting pipe 51 inserted with the end part of the central axis of the mixed core 2, one end of the connecting pipe 51 close to the discharge port of the discharge pipe 3 is in a plugging state, the outer wall of the connecting pipe 51 is fixedly connected with a rotary nozzle 52 in communication with the inside of the connecting pipe 51.

[0026] Specifically, firstly, the mixing core 2 is placed into pipe 1. Then, the mixing core 2 is fixed in pipe 1 by two connectors 4. After the mixing core 2 is fixed, the discharge pipe 3 is connected to one end of pipe 1, and one end of the central shaft of the mixing core 2 is inserted into the connecting pipe 51. Then, the end of pipe 1 away from the discharge pipe 3 is connected to an external feeding device. The feeding device pours various raw materials into pipe 1 and moves them towards the discharge pipe 3. Some of the various raw materials poured into pipe 1 are mixed together by the action of the mixing core 2, while some raw materials are poured into the central shaft of the mixing core 2 and sprayed out from the other end of the central shaft. Since the other end of the central shaft is inserted into the connecting pipe 51, the other end of the central shaft is sprayed out. The raw material ejected from one end enters the connecting pipe 51 and is ejected from the rotating nozzle 52. The rotating nozzle 52 rotates during the ejection of the raw material (the rotating nozzle 52 is existing technology, so it will not be described in detail). Since the connecting pipe 51 is located in the discharge pipe 3, the raw material ejected from the rotating nozzle 52 collides with the raw material flowing between the pipe 1 and the mixing core 2, causing the raw material ejected from the rotating nozzle 52 to resonate and mix with the raw material flowing between the pipe 1 and the mixing core 2. This allows the various raw materials to be mixed more evenly and the mixing effect to be better. Moreover, it is not necessary to use mixing cores 2 of different specifications, so it is not necessary to increase the overall length of the pipe 1, making the discharge speed of the mixed raw material faster.

[0027] Example 1

[0028] like Figure 5 As shown, in this embodiment, both ends of the outer wall of the connecting pipe 51 are fixedly connected with stirring blocks 53 at equal angles in an annular shape, and both ends of the outer wall of the connecting pipe 51 are rotatably connected with rotating rings 54. The outer wall of the rotating rings 54 is fixedly connected with a fixing rod 55 that is fixedly connected to the inner wall of the discharge pipe 3 at equal angles in an annular shape.

[0029] In this embodiment, since the rotary nozzle 52 is fixedly connected to the connecting pipe 51, the rotary nozzle 52 can rotate multiple stirring blocks 53 when it rotates, thereby stirring and mixing the raw materials gathered in the discharge pipe 3 again, making the mixture of multiple raw materials more thorough.

[0030] Example 2

[0031] like Figure 4 As shown, in this embodiment, threaded grooves 21 are provided at both ends of the outer wall of the central shaft of the mixing core 2. The connector 4 includes a flange ring 3 41 that is detachably connected to the pipe 1 and the discharge pipe 3. The flange ring 3 41 is provided with a threaded sleeve 42 that is screwed into the threaded groove 21 at the corresponding position. The outer wall of the threaded sleeve 42 is provided with a collar 43. The outer wall of the collar 43 is fixedly connected with a plurality of fixing rods 1 44 that are fixedly connected to the flange ring 3 41 at the corresponding position at equal angles. The threaded sleeve 42 slides through the collar 43 at the corresponding position. A hexagonal block 45 is fixedly connected to one end of the outer wall of the threaded sleeve 42.

[0032] In this embodiment, the mixing core 2 is first inserted into the pipe 1. Then, one of the flange rings 3 41 is abutted against the flange ring 11 at the corresponding position, and one end of the central shaft of the mixing core 2 is inserted into the collar 43 at the corresponding position. Then, the threaded sleeve 42 is screwed into the threaded groove 21 at the corresponding position. During the screwing process, the threaded sleeve 42 moves forward and is inserted into the collar 43 at the corresponding position until the hexagonal block 45 is tightly abutted against the collar 43 at the corresponding position. Then, the threaded sleeve 42 in the other connector 4 is screwed into the threaded groove 21 at the corresponding position in the same way. At this time, the mixing core 2 is fixed in the pipe 1 by the two flange rings 3 41, which can prevent the mixing core 2 from shaking in the pipe 1.

[0033] Example 3

[0034] like Figure 2 As shown, in this embodiment, flange ring 11 is fixedly connected to both ends of pipe 1, and flange ring 31 is fixedly connected to one end of discharge pipe 3.

[0035] In this embodiment, one end of the pipe 1 connected to the external feeding equipment is fixed to the outlet of the feeding equipment by bolts using flange ring 3 41 and flange ring 11. The other end of the pipe 1 is fixed together with flange ring 11, flange ring 2 31 and flange ring 3 41 by bolts. At this time, the mixing core 2 is completely limited and fixed inside the pipe 1, and the discharge pipe 3 is also fixed at the end of the pipe 1.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
