Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically to a rotary kiln particle mixing and heat transfer oscillating blade assembly. Background Technology

[0002] Rotary kiln heat transfer blades are typically installed inside the kiln. These blades increase the contact area between the material and the hot airflow, allowing heat to be transferred to the material more effectively. The design of the heat transfer blades causes the material to be continuously lifted and scattered during rotation, increasing the number of times the material is turned over, thereby improving the uniformity of heating. The special design of the heat transfer blades can optimize the airflow distribution inside the kiln, reduce dead zones in the airflow, and ensure that heat can be evenly transferred to every material particle.

[0003] However, in actual operation, the inventors found the following problems: In the existing technology, the distribution of airflow is achieved by heat transfer blades to reduce dead air angles and ensure that heat can be evenly transferred to each material particle. However, in actual operation, the airflow is somewhat unstable, and the airflow speed generated by the upper and lower airflows is also different. As a result, the heat transfer effect when using heat transfer blades is different, which affects the heat contact effect of particulate materials inside the rotary kiln.

[0004] Based on this, the present invention provides a rotary kiln particle mixing and heat transfer oscillating blade assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rotary kiln particle mixing and heat transfer oscillating blade assembly, which has the advantages of uniform airflow oscillation and conduction, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a rotary kiln particle mixing and heat transfer oscillating blade assembly, including a pre-installation ring block and a locking ring block. A conical conveying shell is fixedly connected inside the locking ring block. A cylindrical conveying shell is fixedly connected to the side of the conical conveying shell. An installation groove is opened on the side of the cylindrical conveying shell. A rotating shaft is fixedly installed inside the installation groove. Oscillating blades are rotatably connected to the surface of the rotating shaft. A connecting base plate is fixedly installed on the top of the oscillating blades. A second hinge block is hinged inside the connecting base plate. A cylinder is fixedly connected to the side of the second hinge block. A first hinge block is fixedly connected to the other end of the cylinder. A first hinge seat is hinged inside the first hinge block. A cylindrical conveying shell is fixedly connected to the bottom of the first hinge seat.

[0007] Preferably, the side of the pre-installed ring block is provided with several screw holes, and the internal threads of the screw holes are connected to fastening screws. The surface of the fastening screws is attached to a linkage plate, and the other end of the linkage plate is attached to another set of fastening screws. The surface of the other set of fastening screws is threadedly connected to the engaging ring block.

[0008] Preferably, a heat flow uniform plate is fixedly installed inside the cylindrical conveying shell, and an airflow main flow mesh is opened at the center of the heat flow uniform plate, and a plurality of uniform heat dissipation meshes are opened through the heat flow uniform plate.

[0009] Preferably, the pre-installed ring block is pre-installed inside the rotary kiln by welding.

[0010] Preferably, the interior of the pre-installed ring block cavity fits into the outer arc surface of the engaging ring block.

[0011] Preferably, the conical conveyor shell is wider on the left and narrower on the right.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This rotary kiln particle mixing heat transfer oscillating blade assembly is pre-installed into the rotary kiln by welding a pre-installed ring block. Then, a linkage plate aligns with the screw holes in the pre-installed ring block and the engaging ring block, and two sets of fastening screws are screwed in for rotational installation. The engaging ring block is then installed inside the pre-installed ring block. The shape of the conical conveying shell fixed to the side of the engaging ring block causes the incoming airflow to converge. The airflow is ensured by the main airflow mesh in the heat flow uniform plate inside the cylindrical conveying shell, and the airflow is uniformly flowed forward inside the cylindrical conveying shell by several uniform heat dissipation meshes. The extension and retraction of a cylinder controls the hinge blocks at both ends to rotate within the hinge seat and connecting base plate, respectively. This causes the oscillating blades fixed to the bottom of the connecting base plate to rotate on the surface of the rotating shaft. During rotation, several oscillating blades tend to oscillate outwards inside the cylindrical conveying shell, further homogenizing the airflow. The entire operation achieves uniform airflow through the perforations, ensuring uniform heat transfer. Attached Figure Description

An installation groove 5 is provided on the side of the cylindrical conveying shell 4. A rotating shaft 706 is fixedly installed inside the installation groove 5. An oscillating blade 7 is rotatably connected to the surface of the rotating shaft 706. A connecting base plate 705 is fixedly installed on the top of the oscillating blade 7. A second hinge block 704 is hinged inside the connecting base plate 705. A cylinder 703 is fixedly connected to the side of the second hinge block 704. A first hinge block 702 is fixedly connected to the other end of the cylinder 703. A first hinge seat 701 is hinged inside the first hinge block 702. The bottom of the first hinge seat 701 is fixed. The cylindrical conveyor shell 4 is connected to the pre-installed ring block 1. Several screw holes are opened on the side of the pre-installed ring block 1, and fastening screws 102 are connected to the internal threads of the screw holes. A linkage plate 101 is attached to the surface of the fastening screw 102. Another set of fastening screws 102 is attached to the other end of the linkage plate 101. The surface of the other set of fastening screws 102 is threadedly connected to the locking ring block 2. A heat flow uniform plate 6 is fixedly installed inside the cylindrical conveyor shell 4. An airflow main flow mesh 601 is opened at the center of the heat flow uniform plate 6. Several uniform heat dissipation meshes 602 are opened through the heat flow uniform plate 6. The pre-installed ring block 1 is pre-installed inside the rotary kiln by welding. The inside of the cavity of the pre-installed ring block 1 is fitted with the outer arc surface of the locking ring block 2. The conical conveyor shell 3 is shaped with a left-wide and right-narrow shape.

[0021] The working principle involves pre-installing the pre-installed ring block 1 into the rotary kiln via welding. Then, the linkage plate 101 is aligned with the screw holes on the pre-installed ring block 1 and the engaging ring block 2. Two sets of fastening screws 102 are then screwed in and rotated, thus installing the engaging ring block 2 inside the pre-installed ring block 1. The shape of the conical conveyor shell 3, fixedly connected to the side of the engaging ring block 2, causes the incoming airflow to converge. The airflow is further ensured by the main airflow mesh 601 on the heat flow equalization plate 6 inside the cylindrical conveyor shell 4. The heat flow uniform plate 6 has several uniform heat dissipation meshes 602 that make the airflow uniform and flow forward inside the cylindrical conveying shell 4. The extension and retraction of the cylinder 703 can control the hinge block 1 702 and hinge block 2 704 at both ends to hinge and rotate inside the hinge seat 1 701 and the connecting base plate 705, respectively. This causes the swing blades 7 fixedly connected to the bottom of the connecting base plate 705 to rotate on the surface of the rotating shaft 706. During the rotation, the swing blades 7 tend to swing outward inside the cylindrical conveying shell 4, which makes the airflow more uniform as it passes through.
