Description

Technical Field

[0001] This utility model relates to the technical field of PVC stabilizer preparation, and specifically to an airflow mixer for PVC stabilizer preparation. Background Technology

[0002] The airflow continuous mixer mainly uses airflow to continuously mix PVC stabilizers and other components. The airflow mixer sends compressed air into the mixing chamber through the nozzle on the mixing head. The material instantly rises spirally along the cylinder wall with the compressed air, forming a fluidized mixing state. After several pulse blowing and pause intervals, the material in the whole volume can be quickly and uniformly mixed.

[0003] When mixing PVC stabilizers in an airflow mixer, some of the material will adhere to the inner wall of the mixer. However, the mixer lacks an internal cleaning mechanism, which makes the adhered material easy to solidify on the inner wall of the mixer, affecting the quality of the material mixing. In addition, the discharge end of the mixer is a pipe or solenoid valve structure. During the airflow mixing process, the material will accumulate in large quantities, affecting the discharge speed. Summary of the Invention

[0004] The purpose of this invention is to provide an airflow mixer for preparing PVC stabilizers, so as to solve the above-mentioned defects caused by the prior art.

[0005] An airflow mixer for preparing PVC stabilizers includes an ultrasonic cleaning tank, a cleaning trough, and a motor. The ultrasonic cleaning tank contains a cleaning solution, and the cleaning trough is horizontally immersed in the cleaning solution. The cleaning trough has a U-shaped cross-section and a rectangular through-hole at its bottom. Fan-shaped connecting plates are symmetrically welded to the left and right sides of the through-hole. Several support rollers are rotatably connected between the two connecting plates. Driven wheels are installed at both ends of the support rollers. The motor has a pair of symmetrically installed on the left and right sides of the cleaning trough. Drive wheels are installed on the output shaft of the motor. The drive wheels are connected to the driven wheels on the same side via a transmission belt.

[0006] Preferably, the mixing mechanism includes an injection pipe, an air inlet pipe II, a drive shaft, an impeller disc body, an eccentric disc, and mixing rods. The injection pipe is disposed through one side of the cover body. The impeller disc body is disposed inside the cover body. An air inlet pipe II is disposed on one side of the impeller disc body. One end of the air inlet pipe II is connected through one side of the cover body. The drive shaft is mounted on the bottom end of the impeller disc body. An eccentric disc is connected to the bottom end of the drive shaft. Multiple sets of mixing rods are connected to the outer side of the eccentric disc. The eccentric disc is disposed at the bottom end of the mixing shell.

[0007] Preferably, the drive shaft is connected to multiple sets of mixing rods via an eccentric disc connected by an outer key.

[0008] Preferably, the impeller disk body is connected to the outer side of the impeller disk body via a drive shaft located at the bottom end.

[0009] Preferably, the cleaning mechanism includes a cover, a slot, a cleaning brush, a cleaning rod, and an air inlet pipe. An impeller disc is disposed inside the cover, and a cleaning rod is disposed directly below the impeller disc. A drive shaft is connected through the outer side of the cleaning rod, and a cleaning brush is connected to one side of the cleaning rod. One end of the air inlet pipe is connected to one side of the mixing housing, and the cleaning rod is disposed inside the mixing housing.

[0010] Preferably, the cleaning rod is connected to one side of the cleaning brush bar via a slot on one side.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. While using compressed high-speed airflow to stir the material, the compressed air drives the mixing rod to mix, thereby accelerating the mixing speed and uniformity of the mixed material, avoiding material stacking that affects the feeding speed. After being dispersed by the eccentric disc on the drive shaft and the mixing rod, it is further dispersed by the airflow. Finally, under the dual action of the mixing blades and the airflow at the air inlet, the mixing is ensured to be uniform.

[0013] 2. The cleaning rod is connected to one side of the cleaning brush bar through a slot on one side, which facilitates the disassembly and removal of the cleaning brush bar and the cleaning rod. This avoids the cleaning brush bar being inside the mixing shell, which would cause increased wear on the cleaning brush bar. The rotating cleaning brush bar removes residual materials adhering to the shell, mixer, stirring blades and other components. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an airflow mixer for preparing PVC stabilizer includes a support 1, a drive shaft 8, and a cleaning rod 12. A mixing shell 2 is connected to the outside of the support 1. The bottom end of the mixing shell 2 is symmetrically connected to the input end of a solenoid valve 6. A mixing mechanism 5 is provided inside the mixing shell 2. The mixing mechanism 5 mixes the materials inside the mixing shell 2 with airflow and uses compressed gas to drive the mixing rod 15 to rotate and mix, thereby avoiding blockage during unloading. A cleaning mechanism 16 is provided outside the drive shaft 8. The cleaning mechanism 16 cleans the inner wall of the mixing shell 2, thereby preventing PVC particles from adhering and affecting the uniformity of mixing.

[0023] In this embodiment, the mixing mechanism 5 includes a feeding pipe 4, an air inlet pipe 13, a drive shaft 8, an impeller disc 9, an eccentric disc 14, and mixing rods 15. The feeding pipe 4 is disposed through one side of the cover 3. The impeller disc 9 is disposed inside the cover 3. An air inlet pipe 13 is disposed on one side of the impeller disc 9. One end of the air inlet pipe 13 is connected through one side of the cover 3. The drive shaft 8 is installed at the bottom end of the impeller disc 9. The bottom end of the drive shaft 8 is connected to the eccentric disc 14. Multiple sets of mixing rods 15 are connected to the outside of the eccentric disc 14. The eccentric disc 14 is disposed at the bottom end inside the mixing shell 2. The impeller disc 9 is driven by the air inlet pipe 13, and the impeller disc 9 drives the mixing rods 15 to rotate synchronously for mixing.

[0024] In this embodiment, the drive shaft 8 is connected to multiple sets of mixing rods 15 via an eccentric disk 14 connected by an outer key. The symmetrically arranged eccentric disk 14 drives the mixing rods 15 to rotate, avoiding the accumulation of stacked materials that affects the feeding speed.

[0025] In this embodiment, the impeller disc 9 is connected to the outside of the impeller disc 9 via a drive shaft 8 at the bottom. The drive shaft 8 drives the impeller disc 9 to rotate, which in turn drives the cleaning brush 11 to rotate, cleaning the inside of the mixing shell 2.

[0026] In this embodiment, the cleaning mechanism 16 includes a cover 3, a slot 10, a cleaning brush 11, a cleaning rod 12, and an air inlet pipe 7. An impeller disc 9 is disposed inside the cover 3, and a cleaning rod 12 is disposed directly below the impeller disc 9. A drive shaft 8 is connected through the outer side of the cleaning rod 12, and the cleaning brush 11 is connected to one side of the cleaning rod 12. One end of the air inlet pipe 7 is connected to one side of the mixing shell 2. The cleaning rod 12 is disposed inside the mixing shell 2, and the cleaning rod 12 is used to clean the inside of the mixing shell 2, thereby reducing the amount of deposits inside the mixing shell 2.

[0027] In this embodiment, the cleaning rod 12 is connected to one side of the cleaning brush 11 through a slot 10 on one side. The cleaning brush 11 is engaged and assembled through the slot 10, which facilitates the cleaning brush 11 in cleaning the residual material inside the mixing shell 2.

[0028] In practical applications, the airflow mixer prepared with this PVC stabilizer includes the following tasks:

[0029] Step 1: Before use, the material is first injected into the interior of the mixing shell 2 through the multiple sets of injection pipes 4 set at the top. At the same time, the high-pressure gas is directly injected into the interior of the mixing shell 2 through the air inlet pipe 7. The gas is sent into the mixing chamber through the nozzle on the mixing head. The material rises spirally along the cylinder wall with the compressed air, forming a fluidized mixing state. At the same time, the high-pressure gas is injected into the interior of the cover 3 through the air inlet pipe 13, which in turn drives the impeller disc 9 at the top of the mixing rod 15 to blow.

[0030] Step 2: The impeller disc 9 rotates inside the cover 3, driving the drive shaft 8 and eccentric disc 14 to rotate. The eccentric disc 14 drives multiple sets of mixing rods 15 to rotate, and the mixing rods 15 perform secondary mixing of the material. This prevents the material from piling up at the bottom of the mixing shell 2 during the discharge process of the solenoid valve 6, thus ensuring the uniformity of material discharge. The solenoid valve 6 is then opened to discharge the mixed material directly from inside the mixing shell 2.

[0031] Step 3: After the materials are mixed, the operator inserts the cleaning brush 11 into the slot 10. The slot 10 on the outside of the cleaning rod 12 is used to connect with one side of the cleaning brush 11. Then, the impeller disc 9 rotates inside the cover 3. The impeller disc 9 drives the cleaning rod 12 and the cleaning brush 11 to rotate. The cleaning brush 11 cleans the inside of the mixing shell 2 during the rotation, reducing the dirt inside.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
