Existing reactors usually use stirring and mixing devices to agitate the raw materials. However, these devices do not mix the raw materials evenly enough, and during the chemical reaction, sediment may accumulate on the inner wall of the mixing tank, thus affecting the production of PAC.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0025] Please see Figure 1 - Figure 4 The reactor for preparing polyaluminum chloride containing aluminum tail liquid in this embodiment includes a stirring tank 1 and a feed pipe 2 set at the upper end of the stirring tank 1. A discharge pipe 4 is set on one side of the stirring tank 1, and a one-way valve 5 is installed through the upper end of the discharge pipe 4. A connecting pipe is installed through the other side of the stirring tank 1. A suction device 6 is set at one end of the connecting pipe, and the suction device 6 and the connecting pipe are connected through each other. A motor 3 is set above the stirring tank 1. The output shaft of the motor 3 is connected through the stirring tank 1. A fixing plate 15 is fixedly connected to the upper end of the motor 3. One end of the fixing plate 15 is fixedly connected to the outside of the stirring tank 1. A rotating mechanism is set inside the stirring tank 1.
[0026] The rotating mechanism includes a rotating disk 16 for rotation, a gear 17 for pulling, and a circular toothed plate 7 for providing rotational support;
[0027] The feeding pipe 2 and the discharge pipe 4 are both through the mixing tank 1. The rotating disk 16 is fixedly connected to the side of the output shaft of the motor 3. The circular toothed plate 7 is fitted inside the mixing tank 1.
[0028] A fixed shaft 14 is provided through one end of the rotating disk 16 away from the center, and a limit block is fixedly connected to the upper end of the fixed shaft 14.
[0029] The removal of sediment accumulated at the bottom of the mixing tank 1 by the suction device 6 and the rotation of the rotating disk 16 by the motor 3 are both existing technologies, and therefore are not described in detail in this embodiment.
[0030] The material is fed into the mixing tank 1 through the feeding pipe 2. At this time, the fixed plate component is rotated by the motor 3. When the fixed plate component rotates, it will drive the mixing component to rotate, so as to achieve the effect of mixing the raw materials inside the mixing tank 1.
[0031] While the motor 3 rotates, the rotating disk 16 will rotate along with the motor 3 and drive the gear 17 to rotate. At this time, the gear 17 will rotate around the circular toothed plate 7. The cleaning component will rotate around the inner wall of the mixing tank 1 along with the gear 17 to remove the sediment accumulated on the inner wall of the mixing tank 1, so as to prevent the debris accumulated on the inner wall of the mixing tank 1 from affecting the preparation of raw materials. When the raw materials are prepared, the prepared raw materials will flow out from the discharge pipe 4 by opening the one-way valve 5. The sediment accumulated at the bottom of the mixing tank 1 can be extracted by starting the suction device 6 to remove the accumulated material.
[0032] By setting the fixed shaft 14 and the rotating disk 16 to be through-through, the problem of the fixed shaft 14 getting stuck when it rotates with the rotating disk 16 can be prevented. The limiting block at the upper end of the fixed shaft 14 can fix the longitudinal position of the fixed shaft 14, preventing the fixed shaft 14 from sliding out of the rotating disk 16 when it rotates.
[0033] A connecting plate 8 is fixedly connected to the lower end of the fixed shaft 14, and a rotating shaft is rotatably connected to the lower end of the connecting plate 8.
[0034] Gear 17 is rotatably connected to the lower end of the rotating shaft. Gear 17 is set inside the circular toothed plate 7 and meshes with the circular toothed plate 7. Rotating rod 9 is rotatably connected to the lower end of gear 17. Scraper 10 is fixedly connected to the circumference of rotating rod 9.
[0035] A disc 11 is provided below the rotating disc 16. The disc 11 is fixedly connected to one end of the output shaft of the motor 3, and several rotating rods 12 are fixedly connected to the lower end of the disc 11.
[0036] Several stirring blades 13 are fixedly connected to the circumference of the rotating rod 12, and the included angle between the several stirring blades 13 is α, and 130° > α > 100°;
[0037] By rotating the shaft to the lower end of the connecting plate 8, when the connecting plate 8 rotates with the rotating disk 16, the connecting plate 8 will pull the gear 17 to rotate. By meshing the gear 17 with the circular toothed plate 7, the gear 17 will rotate around the inner wall of the circular toothed plate 7 when it rotates, thus limiting the rotation position of the gear 17.
[0038] The rotating rod 9 is fixedly connected to the lower end of the gear 17. When the gear 17 rotates, it will drive the rotating rod 9 to rotate. The scraper 10 set around the rotating rod 9 will rotate around the inner wall of the mixing tank 1 to remove the sediment accumulated on the inner wall of the mixing tank 1. The scraper 10 is made of soft rubber material, so it will not scratch the inner wall of the mixing tank 1 when it removes the sediment. The disc 11 is fixedly connected to one end of the output shaft of the motor 3. When the motor 3 rotates, it will drive the disc 11 to rotate synchronously.
[0039] Several rotating rods 12 are fixedly connected to the lower end of the disc 11. The rotating rods 12 will rotate with the disc 11. Several stirring blades 13 at a certain angle are set around the rotating rods 12. When the stirring blades 13 rotate, the raw materials inside the mixing tank 1 will be evenly stirred, preventing the raw materials from having too much sediment due to uneven stirring.
[0040] The working principle of the above embodiments is as follows:
[0041] In use, raw materials are added into the mixing tank 1 through the feed pipe 2. The motor 3 is started to drive the disc 11 to rotate. The rotating rod 12 will drive the mixing blade 13 to rotate with the disc 11. At the same time as the motor 3 starts, the rotating disc 16 will also rotate with the motor 3. The rotating disc 16 pulls the gear 17 to rotate around the inner wall of the circular toothed plate 7 through the connecting plate 8. The scraper 10 on the side of the rotating rod 9 will rotate around the inner wall of the mixing tank 1 with the gear 17, so as to remove the sediment accumulated on the inner wall of the mixing tank 1.
[0042] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
