Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln equipment, specifically to an internal support device for a rotary kiln burner. Background Technology

[0002] In rotary kilns, the central pipe is usually connected to the burner body via a rotary connection. The central pipe is mainly used to transport combustion-supporting gas or denitrification medium into the kiln.

[0003] Patent (CN220981339U) discloses a cement rotary kiln burner, relating to the field of rotary kiln technology. It includes a central tube with an outer sleeve fitted around it, forming a gas chamber between the central tube and the outer sleeve. A first baffle is fixedly installed on one side of the gas chamber, with several first air distribution holes on the first baffle. Inside the outer sleeve, on one side of the central tube, a second baffle, a third baffle, and a rectifier block are sequentially arranged. The second baffle has several second air distribution holes, the third baffle has a central hole, and the rectifier block has several vent holes. This invention uses a guide cone to disperse the gas discharged from the central tube. The dispersed gas mixes with the combustion-supporting gas ejected from the first air distribution holes and is then discharged through the second air distribution holes. The central hole on the third baffle gathers the gas discharged from the second air distribution holes, achieving secondary gas fusion. The vent holes on the rectifier block change the flow path of the mixed gas.

[0004] The rotary kiln burner in the aforementioned patent, as well as most rotary kiln burners on the market, are prone to deformation and increased vibration due to the long central pipe inside the rotary kiln and the lack of support. This can lead to damage, failure, or even further danger. Summary of the Invention

[0005] The purpose of this invention is to provide an internal support device for a rotary kiln burner to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a kiln internal support device for a rotary kiln burner, comprising a triangular support assembly and an installation cylinder. The triangular support assembly is disposed on the outer wall of the installation cylinder, and guide assemblies are symmetrically arranged on both sides of the outer wall of the installation cylinder. The triangular support assembly includes an outlet support pipe and two support feet. The outlet support pipe is vertically disposed at the top of the outer wall of the installation cylinder, and the two support feet are symmetrically inclined on both sides of the outer wall of the installation cylinder. The end of the support foot away from the installation cylinder passes through the kiln bricks of the kiln body and is fixedly connected to the kiln lining. The end of the outlet support pipe away from the installation cylinder extends to the outside of the kiln body and is slidably fitted with a dustproof sleeve, which is fixedly connected to the outer wall of the kiln body.

[0007] Furthermore, the outlet support pipe and the two support feet are radially distributed at a 120-degree angle on the outer wall of the mounting cylinder.

[0008] Furthermore, the guiding assembly includes a guide wheel and two rollers that are rotatably connected, and the guide wheel and the two rollers are distributed in an isosceles triangle.

[0009] Furthermore, the outer wall of the guide wheel has an arc-shaped structure with a concave center and convex sides.

[0010] Furthermore, the two rollers are located between the outlet support pipe and the guide wheel, and the support foot is located between the guide wheel and the rollers.

[0011] Furthermore, a first welded mesh is fitted on the outer wall of the support base, and a second welded mesh is fitted on the outer wall of the dustproof sleeve outside the outlet support pipe. The second welded mesh is fixedly connected to the dustproof sleeve through a baffle ring.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] 1. This utility model, through the setting of a triangular support assembly, an installation cylinder, a guide assembly, an outlet support pipe, a support base, and a dustproof sleeve, allows for the effective suspending of the installation cylinder by directly connecting the triangular support assembly to the kiln body. The triangular support assembly forms a triangular support structure on the outside of the central pipe, effectively improving the safety and stability of the central pipe and reducing radial runout caused by gravity deformation and internal impact, thus significantly enhancing product reliability and safety. The outlet support pipe is fitted with a dustproof sleeve, allowing it to move vertically relative to the kiln lining to eliminate relative displacement caused by kiln expansion and contraction deformation, preventing tearing of the outlet support pipe. The guide wheel and two rollers in the guide assembly provide rolling support at three points on the outer wall of the central pipe, effectively improving its safety and stability, further reducing radial runout caused by gravity deformation and internal impact, and significantly enhancing product reliability and safety.

[0014] 2. In this utility model, the guide wheel and two rollers are designed to be distributed in an isosceles triangle, which limits the position of the guide wheel and rollers, allowing them to better support the central pipe and effectively improve the rolling support effect of the central pipe. The outer wall of the guide wheel has an arc-shaped structure with a concave center and convex sides. The design of the outer wall structure of the guide wheel makes the surface of the guide wheel fit better with the central pipe, thereby improving the rolling support effect of the central pipe.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a kiln internal support device for a rotary kiln burner, comprising a triangular support assembly 1 and an installation cylinder 2. The triangular support assembly 1 is disposed on the outer wall of the installation cylinder 2. Guide assemblies 3 are symmetrically arranged on both sides of the outer wall of the installation cylinder 2. The triangular support assembly 1 includes an outlet support pipe 101 and two support feet 102. The outlet support pipe 101 is vertically disposed at the top of the outer wall of the installation cylinder 2. The two support feet 102 are symmetrically inclined on both sides of the outer wall of the installation cylinder 2. The end of the support foot 102 away from the installation cylinder 2 passes through the kiln bricks of the kiln body and is fixedly connected to the kiln lining. The end of the outlet support pipe 101 away from the installation cylinder 2 extends to the outside of the kiln body and is slidably fitted with a dustproof sleeve 103. The dustproof sleeve 103 is fixedly connected to the outer wall of the kiln body. The guide assembly 3 includes a rotatably connected guide wheel 301 and two rollers 302. The guide wheel 301 and the two rollers 302 are distributed in an isosceles triangle. The outer wall of the guide wheel 301 is an arc-shaped structure with a concave center and convex sides.

[0023] In one embodiment, the outlet support pipe 101 and the two support feet 102 are radially distributed at a 120-degree angle on the outer wall of the mounting cylinder 2, and the triangular support assembly 1 is radially installed in the kiln body at 120° equal intervals. The mounting cylinder 2 at the center of the triangular support assembly 1 is fixedly connected to the central pipe, which can effectively ensure the stability and safety of the support for the central pipe.

[0024] In one embodiment, two rollers 302 are disposed between the outlet support pipe 101 and the guide wheel 301, and the support foot 102 is disposed between the guide wheel 301 and the rollers 302, so that the triangular support assembly 1 and the guide assembly 3 form two symmetrical intersecting triangles to support the central pipe, which can effectively improve the safety and stability of the central pipe during use.

[0025] In one embodiment, a first welded mesh 104 is fitted on the outer wall of the support foot 102, and a second welded mesh 105 is fitted on the outer wall of the dustproof sleeve 103 outside the outlet support pipe 101. The second welded mesh 105 is fixedly connected to the dustproof sleeve 103 through a baffle ring 106. The dustproof sleeve 103 and the outer sides of the two support feet 102 are wrapped with castable refractory by welding the mesh with welded nails. The top of the castable refractory is cast integrally with the kiln bricks and the top is sealed to the baffle ring 106. The baffle ring 106 is welded to the outer wall of the dustproof sleeve 103 to form a labyrinth structure, making it difficult for particles, dust, and lumps to escape.

[0026] The working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-4 This utility model includes a triangular support assembly 1, an installation cylinder 2, a guide assembly 3, an outlet support pipe 101, a support foot 102, and a dustproof sleeve 103. The installation cylinder 2 provides an installation position for the central pipe of the burner. The triangular support assembly 1 provides triangular support on the outside of the installation cylinder 2 and is directly connected to the kiln body. This effectively suspends the installation cylinder 2. The triangular support assembly 1 forms a triangular support structure on the outside of the central pipe, which can effectively improve the safety and stability of the central pipe and reduce the radial runout of the central pipe caused by gravity deformation and internal impact, thus greatly improving the reliability and safety of the product.

[0028] The outlet support pipe 101 is fitted with a dustproof sleeve 103 on the outside. The outlet support pipe 101 can move vertically relative to the kiln skin to eliminate the relative displacement caused by the expansion and contraction deformation of the kiln body and prevent the outlet support pipe 101 from being torn.

[0029] The guide assembly 3 provides guidance and support to the outer wall of the central pipe on both sides of the outer wall of the mounting cylinder 2, which can further improve the safety and stability of the central pipe. The guide wheel 301 and the two rollers 302 in the guide assembly 3 provide rolling support in three directions on the outer wall of the central pipe, which can effectively improve the safety and stability of the central pipe, thereby further reducing the radial runout of the central pipe caused by gravity deformation, internal impact, etc., and greatly improving the reliability and safety of the product.

[0030] The guide wheel 301 and two rollers 302 are designed in an isosceles triangle configuration. This design limits the positions of the guide wheel 301 and rollers 302, allowing them to better support the central pipe and effectively improve its rolling support. The guide wheel 301 has an arc-shaped outer wall with a concave center and convex sides. This design enhances the surface contact between the guide wheel 301 and the central pipe, further improving its rolling support.

[0031] 1. Through the design of the triangular support component 1, the triangular stable structure can effectively reduce the radial runout of the central pipe caused by gravity deformation, internal impact, etc., and greatly improve the reliability and safety of the product.

[0032] 2. By designing the guide component 3, rolling guide support is provided on the surface of the central pipe, which can further reduce the radial runout of the central pipe caused by gravity deformation, internal impact, etc., and greatly improve the reliability and safety of the product.

[0033] 3. The sliding design of the dustproof sleeve 103 and the outlet support pipe 101 can eliminate the relative displacement caused by the expansion and contraction deformation of the kiln body, prevent the outlet support pipe 101 from being torn, and further improve safety.

[0034] 4. The maze-like structural design avoids dust pollution.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
