Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and more specifically to a mixing device for zinc-modified magnesium-aluminum hydrotalcite. Background Technology

[0002] Zinc-modified magnesium-aluminum hydrotalcite is a material modified by introducing zinc ions into magnesium-aluminum hydrotalcite. This modified material exhibits excellent performance in PVC (polyvinyl chloride) heat stabilizers, acting synergistically with calcium-zinc primary stabilizers to enhance coordination stabilization and thus extend the thermal stability time. Currently, mixing is a necessary step in the processing of zinc-modified magnesium-aluminum hydrotalcite, directly affecting the final properties and application effects of the material.

[0003] Currently, when mixing zinc-modified magnesium-aluminum hydrotalcite, the stirring rod of the mixing device is usually used to stir the material to make it evenly mixed. However, when the material is stirred and mixed by the stirring rod alone, the stirring range of the stirring rod is limited, and the material lacks fluidity during stirring. Some materials located at the bottom of the inner cavity of the device are difficult to be fully mixed, which reduces the mixing effect to a certain extent and needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mixing device for zinc-modified magnesium-aluminum hydrotalcite, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a mixing device for zinc-modified magnesium-aluminum hydrotalcite, comprising a mixing tank, a rotating shaft rotatably mounted on the top of the mixing tank via a sealed bearing, the bottom end of the rotating shaft extending to the lower part of the mixing tank and fixedly mounted with an arc-shaped mounting plate, scrapers fixedly connected to both sides of the bottom of the arc-shaped mounting plate, one side of the scraper overlapping the lower part of the inner wall of the mixing tank, a mixing lifting shell fixedly mounted on the right side of the mixing tank, a connecting shaft provided inside the mixing lifting shell, spiral lifting blades fixedly mounted on the outer wall of the connecting shaft, a second motor fixedly mounted on the top of the mixing lifting shell, the output end of the second motor extending to the interior of the mixing lifting shell and fixedly mounted on the top of the connecting shaft via a coupling, and the bottom end of the connecting shaft rotatably mounted on the bottom of the inner wall of the mixing lifting shell via a sealed bearing.

[0006] Furthermore, a mounting bracket is fixedly installed on the top of the mixing tank, and a No. 1 motor is fixedly installed on the top of the mounting bracket. The output end of the No. 1 motor extends to the bottom of the mounting bracket and is fixedly installed on the top of the rotating shaft via a coupling.

[0007] Furthermore, multiple stirring rods are fixedly installed on the outer wall of the rotating shaft, and the multiple stirring rods are evenly distributed inside the mixing tank.

[0008] Furthermore, a No. 1 feed pipe is fixedly installed on the lower right side of the mixing tank, and a control valve is installed on the No. 1 feed pipe. One end of the No. 1 feed pipe is fixedly installed on the lower left side of the mixing lifting shell.

[0009] Furthermore, a second guide pipe is fixedly installed on the upper left side of the mixing lifting shell, and one end of the second guide pipe is fixedly installed on the right side of the top of the mixing tank.

[0010] Furthermore, a feed inlet is provided on the left side of the top of the mixing tank, and a discharge pipe is fixedly installed in the middle of the bottom of the mixing tank, with a discharge valve installed on the discharge pipe.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the cooperation of a No. 1 feed pipe, a control valve, a mixing lifting shell, a No. 2 motor, a connecting shaft, spiral lifting blades, and a No. 2 feed pipe, can discharge the material from the bottom of the mixing tank into the mixing lifting shell, and use the spiral lifting blades to lift the material upwards. Then, the material is discharged back into the mixing tank through the No. 2 feed pipe, so that the zinc-modified magnesium-aluminum hydrotalcite material circulates during mixing, and is stirred by the stirring rod, so that the material can be mixed quickly and evenly, improving the mixing effect.

[0012] 2. This utility model uses a No. 1 motor and a rotating shaft to drive the stirring rod, the arc-shaped mounting plate and the scraper to rotate. The stirring rod stirs the material, and the scraper can move the material at the bottom of the mixing tank.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The mixing device for zinc-modified magnesium aluminum hydrotalcite involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: like Figure 1-5 As shown, a mixing device for zinc-modified magnesium-aluminum hydrotalcite includes a mixing tank 1. A rotating shaft 22 is rotatably mounted on the top of the mixing tank 1 via a sealed bearing. The bottom end of the rotating shaft 22 extends to the lower part of the mixing tank 1 and is fixedly mounted with an arc-shaped mounting plate 24. Scrapers 25 are fixedly connected to both sides of the bottom of the arc-shaped mounting plate 24. One side of the scraper 25 overlaps the lower part of the inner wall of the mixing tank 1. A mounting frame 2 is fixedly mounted on the top of the mixing tank 1. A No. 1 motor 21 is fixedly mounted on the top of the mounting frame 2. The output end of the No. 1 motor 21 extends to the lower part of the mounting frame 2 and is fixedly mounted on the top of the rotating shaft 22 via a coupling. Multiple stirring rods 23 are fixedly mounted on the outer wall of the rotating shaft 22. The multiple stirring rods 23 are evenly distributed inside the mixing tank 1. A feed inlet 4 is opened on the left side of the top of the mixing tank 1. A discharge pipe 5 is fixedly mounted in the middle of the bottom of the mixing tank 1. A discharge valve 6 is installed on the discharge pipe 5.

[0021] In this embodiment, the cooperation of motor 21 and shaft 22 facilitates the rotation of stirring rod 23, arc-shaped mounting plate 24 and scraper 25. Multiple stirring rods 23 are used to stir and mix the materials, and scraper 25 is used to scrape and move the materials at the bottom of the mixing tank 1, so that the materials at the bottom of the mixing tank 1 can be evenly discharged into the mixing lifting shell 3. The material can be put into the mixing tank 1 through the feed port 4, and the mixed material can be discharged through the discharge pipe 5 and discharge valve 6.

[0022] Example 2: like Figure 1-5As shown, a mixing lifting shell 3 is fixedly installed on the right side of the mixing tank 1. A connecting shaft 33 is provided inside the mixing lifting shell 3. A spiral lifting blade 34 is fixedly installed on the outer wall of the connecting shaft 33. A second motor 32 is fixedly installed at the top of the mixing lifting shell 3. The output end of the second motor 32 extends into the interior of the mixing lifting shell 3 and is fixedly installed at the top of the connecting shaft 33 through a coupling. The bottom end of the connecting shaft 33 is rotatably installed at the bottom of the inner wall of the mixing lifting shell 3 through a sealed bearing. A first guide pipe 31 is fixedly installed at the lower right side of the mixing tank 1. A control valve 311 is installed on the first guide pipe 31. One end of the first guide pipe 31 is fixedly installed at the lower left side of the mixing lifting shell 3. A second guide pipe 35 is fixedly installed at the upper left side of the mixing lifting shell 3. One end of the second guide pipe 35 is fixedly installed at the right side of the top of the mixing tank 1.

[0023] In this embodiment, by setting up the first feed pipe 31 and the control valve 311, the material at the bottom of the mixing tank 1 can be discharged into the mixing lifting shell 3. Through the cooperation of the second motor 32 and the connecting shaft 33, the spiral lifting blades 34 are driven to rotate. The spiral lifting blades 34 lift the material inside the mixing lifting shell 3 upward and discharge the material back into the mixing tank 1 through the second feed pipe 35. This allows the zinc-modified magnesium-aluminum hydrotalcite material to circulate during mixing, thereby improving the mixing efficiency.

[0024] In summary, as Figure 1-5 As shown, this mixing device for zinc-modified magnesium-aluminum hydrotalcite involves feeding the zinc-modified magnesium-aluminum hydrotalcite material into the mixing tank 1 through the feed inlet 4. The output of motor 21 drives the rotating shaft 22 to rotate, which in turn drives the stirring rods 23, the arc-shaped mounting plate 24, and the scraper 25 to rotate inside the mixing tank 1. The stirring rods 23 mix the material, and the scraper 25 moves the material at the bottom of the mixing tank 1. At this time, the control valve 311 can be opened to allow the material at the bottom of the mixing tank 1 to move. The material is discharged into the mixing and lifting shell 3 through the first guide pipe 31, and the connecting shaft 33 and the spiral lifting blade 34 are driven to rotate by the output end of the second motor 32. The spiral lifting blade 34 lifts the material inside the mixing and lifting shell 3 upwards, and discharges the material back into the mixing tank 1 through the second guide pipe 35. This allows the zinc-modified magnesium-aluminum hydrotalcite material to circulate during mixing, and is stirred in conjunction with the stirring rod 23, so that the material can be mixed quickly and evenly. After mixing, the discharge valve 6 is opened, and the material inside the mixing tank 1 is discharged through the discharge pipe 5.
