Description

Technical Field

[0001] This invention relates to the field of rotary kiln equipment technology, and more specifically, to a rotary kiln head air-cooling jacket device that is easy to install, maintain and replace. Background Technology

[0002] Rotary kilns are a type of building materials equipment widely used in industries such as metallurgy, chemicals, building refractory materials, and sanitation. During normal operation of a rotary kiln, the material tends to agglomerate due to excessively high kiln head temperatures. Large pieces of material accumulate at the kiln head, easily causing blockages and resulting in uneven material discharge. This not only affects the normal production of the rotary kiln but also damages the kiln head over time, reducing its service life. Therefore, air-cooled jackets are installed at the kiln head of rotary kilns for cooling.

[0003] Because of the large amount of flying sand at the kiln head, the air-cooled cover will be damaged to a certain extent during long-term use, thus requiring regular inspection and maintenance. In the existing technology, the air-cooled cover and the kiln head are generally connected by an integrated welding process, which makes the inspection and disassembly work more difficult, increases the time required for disassembly and replacement, and also increases the labor force of the workers. Summary of the Invention

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0009] The connecting mechanism includes a connecting plate, which is fixedly connected to the outer surface of one end of the arc-shaped plate. A connecting groove is provided on the outer surface of the other end of the arc-shaped plate near the connecting plate. Two adjacent arc-shaped plates are connected to each other by the connection plate and the connecting groove. A gear is provided on the outer surface of the connecting plate, and a screw is fixedly connected to one end of the gear. The connecting plate, the arc-shaped plate and the kiln head are fixedly connected by screws.

[0010] Furthermore, the lower end of the gear is meshed with a toothed plate, and a groove A is provided on the outer surface of the arc-shaped plate near the toothed plate, and the toothed plate is slidably connected to the groove A.

[0011] Furthermore, a connecting block A is fixedly connected to the outer surface of one end of the arc-shaped plate, and a connecting block B is fixedly connected to the outer surface of the other end of the arc-shaped plate. The connecting block A and the connecting block B are fixedly connected by a nut, and two adjacent arc-shaped plates are fixedly connected by the connecting block A and the connecting block B.

[0012] Furthermore, a slider is uniformly fixedly connected to the front end of the outer surface of the kiln head, and a groove B is provided on the inner surface of the arc plate near the slider. The slider and the groove B are slidably connected in a T-shape.

[0013] Furthermore, the toothed plate and the slide groove A are slidably connected in a T-shape, and the upper and lower outer surfaces of the toothed plate are evenly connected with rolling balls on the side near the slide groove A.

[0014] Furthermore, a screw is rotatably connected to the outer surface of the front end of the toothed plate, and a fixing plate is fixedly connected to the front end of the outer surface of the arc-shaped plate near the screw. The front end of the screw passes through the fixing plate and is connected to it via a threaded drive.

[0015] Furthermore, a cavity is formed on the outer surface of the front end of the toothed plate near the screw, and the cavity is filled with electrorheological fluid. A rotating rod is fixedly connected to the rear end of the screw, and the rear end of the rotating rod extends into the cavity.

[0016] Furthermore, the inner surface of the cavity is uniformly provided with grooves, and the outer surface of the rotating rod is uniformly fixedly connected with protruding rods.

[0018] Furthermore, the curved plate is made of aluminum alloy.

[0019] 3. Beneficial Effects

[0020] Compared with the prior art, the advantages of this invention are:

[0021] (1) The present invention sets up a connecting mechanism to splice four arc-shaped plates together to form an air-cooling hood. The connecting plate and the connecting groove are attached to each other, and the four arc-shaped plates are connected by screws passing through the connecting plate and the arc-shaped plate. The two are connected by screws passing through the arc-shaped plate and the kiln head. When disassembling, the screws can be rotated by rotating the gear. When a certain arc-shaped plate is damaged, the arc-shaped plate can be disassembled and repaired in a directional manner without disassembling other arc-shaped plates, thereby reducing the difficulty of maintenance and replacement work, reducing the time required for disassembly and replacement, and reducing the labor force of the workers.

[0022] (2) By setting a toothed plate, when it is necessary to rotate the gear to drive the screw to rotate for disassembly, it is only necessary to drive the gear to rotate by sliding the toothed plate, so that the screw can rotate accordingly. There is no need for workers to disassemble multiple screws one by one, which further reduces the difficulty of maintenance and replacement work.

[0023] (3) By setting an annular groove and a through groove, when working, cold air is introduced into the air inlet pipe. The cold air passes through the air inlet pipe into the front annular groove and flows out through the through groove from the air outlet pipe, thereby cooling the air-cooled cover.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Please see Figures 1 to 8 A rotary kiln head air-cooled jacket device that is easy to install, maintain, and replace, such as Figures 1 to 4 As shown, it includes a kiln head 1, and an air-cooled shroud 2 is fixedly connected to the front end of the outer surface of the kiln head 1. The air-cooled shroud 2 is composed of four arc-shaped plates 21 spliced ​​together, and the four arc-shaped plates 21 are fixedly connected to each other by a connecting mechanism 3.

[0038] The connecting mechanism 3 includes a connecting plate 31, which is fixedly connected to the outer surface of one end of the arc plate 21. A connecting groove 32 is provided on the outer surface of the other end of the arc plate 21 near the connecting plate 31. Two adjacent arc plates 21 are connected to each other by the connection plate 31 and the connecting groove 32. A gear 34 is provided on the outer surface of the connecting plate 31. A screw 35 is fixedly connected to one end of the gear 34. The connecting plate 31, the arc plate 21 and the kiln head 1 are fixedly connected by the screw 35.

[0039] Because the kiln head 1 produces a lot of flying sand, long-term use will cause a certain degree of damage to the air-cooled cover 2, thus requiring regular inspection and maintenance. In the existing technology, the air-cooled cover 2 and the kiln head 1 are generally connected by an integrated welding process, which makes the inspection and disassembly work difficult, increases the time required for disassembly and replacement, and increases the labor force. The present invention sets up a connecting mechanism 3 to splice four arc-shaped plates 21 together to form the air-cooled cover 2. The connecting plate 31 and the connecting groove 32 are attached to each other, and the four arc-shaped plates 21 are connected by screws 35 passing through the connecting plate 31 and the arc-shaped plates 21. The screws 35 pass through the arc-shaped plates 21 and the kiln head 1 to connect the two. During disassembly, the screws 35 are rotated by rotating the gear 34. When a certain arc-shaped plate 21 is damaged, the arc-shaped plate 21 can be disassembled and repaired in a specific direction without disassembling the other arc-shaped plates 21, thereby reducing the difficulty of inspection and replacement work, reducing the time required for disassembly and replacement, and reducing the labor force.

[0040] As one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the lower end of the gear 34 is meshed with a toothed plate 33, and a groove A36 is provided on the outer surface of the arc plate 21 near the toothed plate 33. The toothed plate 33 is slidably connected to the groove A36.

[0041] By setting a toothed plate 33, when it is necessary to rotate the gear 34 to drive the screw 35 to rotate for disassembly, it is only necessary to drive the gear 34 to rotate by sliding the toothed plate 33, so that the screw 35 can rotate accordingly. This eliminates the need for workers to disassemble multiple screws 35 one by one, further reducing the difficulty of maintenance and replacement work.

[0042] As one embodiment of the present invention, such as Figure 2 As shown, a connecting block A37 is fixedly connected to the outer surface of one end of the arc plate 21, and a connecting block B38 is fixedly connected to the outer surface of the other end of the arc plate 21. The connecting block A37 and the connecting block B38 are fixedly connected by a nut, and two adjacent arc plates 21 are fixedly connected by the connecting block A37 and the connecting block B38.

[0043] The present invention connects four arc-shaped plates 21 by setting connecting block A37 and connecting block B38 and connecting them with nuts, thereby improving the stability of the connection between the arc-shaped plates 21 and preventing the arc-shaped plates 21 from loosening during long-term operation, which could cause gaps in the air-cooled cover 2 and affect the normal operation of the device.

[0044] As one embodiment of the present invention, such as Figure 3 and Figure 5 As shown, a slider 4 is uniformly fixedly connected to the front end of the outer surface of the kiln head 1, and a groove B5 is provided on the inner surface of the arc plate 21 near the slider 4. The slider 4 and the groove B5 are slidably connected in a T-shape.

[0045] This invention improves the stability of the connection between the kiln head 1 and the arc plate 21 by setting the slider 4 and the slide groove to slide in a T-shape. During installation, first align the slide groove with the slider 4, then slide the arc plate 21 to make the slider 4 slide along the slide groove so that the arc plate 21 is installed on the outer surface of the kiln head 1. Then install the remaining arc plates 21 one by one in this way. Since the slider 4 and the slide groove are connected in a T-shape, the arc plate 21 can be prevented from detaching from the outer surface of the kiln head 1 during the installation process. After the installation is completed, install the nut to connect the connecting block A37 and the connecting block B38. Then slide the toothed plate 33 to drive the gear 34 to rotate and drive the screw 35 to rotate, thereby connecting the arc plate 21 and the kiln head 1.

[0046] As one embodiment of the present invention, such as Figure 4 As shown, the toothed plate 33 and the slide groove A36 are slidably connected in a T-shape, and the upper and lower outer surfaces of the toothed plate 33 are evenly connected with rolling balls 39 on the side near the slide groove A36.

[0047] The present invention improves the stability of the connection between the toothed plate 33 and the slide groove A36 by sliding them in a T-shaped structure, thereby preventing the toothed plate 33 and the slide groove A36 from separating from each other. By setting the ball bearing 39, the toothed plate 33 and the slide groove A36 are connected in a rolling manner, which reduces the friction between the toothed plate 33 and the slide groove A36, thus making it easier for the operator to slide the toothed plate 33.

[0048] As one embodiment of the present invention, such as Figure 2 and Figure 6 As shown, a screw 310 is rotatably connected to the outer surface of the front end of the toothed plate 33, and a fixing plate 311 is fixedly connected to the front end of the outer surface of the arc plate 21 near the screw 310. The front end of the screw 310 passes through the fixing plate 311 and is connected to it by a threaded drive.

[0049] The present invention provides a threaded connection between the screw 310 and the fixing plate 311. When the screw 35 becomes loose, the screw 310 can be rotated to drive the screw along the screw groove, thereby sliding the toothed plate 33 and driving the screw 35 to rotate, thus tightening the connection between the arc plate 21 and the kiln head 1.

[0050] As one embodiment of the present invention, such as Figure 6 As shown, a cavity 312 is provided on the outer surface of the front end of the toothed plate 33 near the screw 310. The cavity 312 is filled with electrorheological fluid. A rotating rod 313 is fixedly connected to the rear end of the screw 310. The rear end of the rotating rod 313 extends into the cavity 312.

[0051] This invention provides a cavity 312 filled with electrorheological fluid. Before rotating the screw 310, the electrorheological fluid is de-energized to remain liquid. After the screw 310 is rotated to tighten the screw 35, the electrorheological fluid is energized to solidify it, thereby fixing the screw 310 and preventing it from rotating due to external forces. This would prevent the toothed plate 33 from sliding, causing the gear 34 to rotate and the screw 35 to loosen.

[0052] As one embodiment of the present invention, such as Figure 6 As shown, the inner surface of the cavity 312 is uniformly provided with grooves 314, and the outer surface of the rotating rod 313 is uniformly fixedly connected with protrusions 315.

[0053] By setting the groove 314 and the protrusion 315, the resistance between the electrorheological fluid and the cavity 312 and the rotating rod 313 is increased, which further improves the fixing effect of the screw 310.

[0054] As one embodiment of the present invention, such as Figure 7 and Figure 8 As shown, the arc-shaped plate 21 has arc-shaped grooves 6 at its rear end and center. The arc-shaped grooves 6 are connected to form an annular groove 61. The arc-shaped plate 21 has through grooves 7 evenly distributed between the two annular grooves 61. One side of the outer surface of one of the arc-shaped plates 21 is fixedly connected to an air inlet pipe 8, and the other side of its outer surface is fixedly connected to an air outlet pipe 9. The air inlet pipe 8 is connected to the annular groove 61 at the front end, and the air outlet pipe 9 is connected to the annular groove 61 at the rear end.

[0055] The present invention provides an annular groove 61 and a through groove 7. During operation, cold air is introduced into the air inlet pipe 8. The cold air passes through the air inlet pipe 8 and enters the front annular groove 61, and flows out through the through groove 7 and the air outlet pipe 9, thereby cooling the air-cooled cover 2.

[0056] As one embodiment of the present invention, such as Figure 5 As shown, the arc-shaped plate 21 is made of aluminum alloy.

[0057] Aluminum alloy is a good thermal conductor. By making the arc plate 21 out of aluminum alloy, it is easy to absorb the heat generated at the kiln head 1, and then the heat is carried away by the cold air, thereby improving the heat dissipation effect of the device on the kiln head 1.

[0058] Instructions for use: During installation, first align the slide groove with the slider 4, then slide the arc plate 21 to allow the slider 4 to slide along the slide groove, thus installing the arc plate 21 onto the outer surface of the kiln head 1. Then install the remaining arc plates 21 one by one in this manner. Because the slider 4 and the slide groove are connected in a T-shape, the arc plate 21 can be prevented from detaching from the outer surface of the kiln head 1 during installation. After installation, install the nut to connect the connecting block A37 and the connecting block B38. Then slide the toothed plate 33 to drive the gear 34 to rotate, causing the screw 35 to rotate accordingly, thereby securing the arc plate 21 to the kiln head 1. When screw 35 becomes loose, the electrorheological fluid is de-energized and becomes liquid. The screw 310 can be rotated to drive the fluid along the screw groove, thereby sliding the toothed plate 33 and driving screw 35 to rotate, thus tightening the connection between the arc plate 21 and the kiln head 1. Then, the electrorheological fluid is energized to solidify it, thereby fixing screw 310. By setting an annular groove 61 and a through groove 7, cold air is introduced into the air inlet pipe 8 during operation. The cold air passes through the air inlet pipe 8 and enters the front annular groove 61, and flows out through the through groove 7 and the air outlet pipe 9, thereby cooling the air-cooled cover 2.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
