Description

Technical Field

[0001] This utility model relates to the field of industrial furnace technology, and in particular to the impeller blade structure of a bell-type annealing furnace for preventing ash accumulation. Background Technology

[0002] Bell-type annealing furnaces are widely used in industrial production for the heat treatment of metal materials. They mainly rely on the high-speed rotation of the impeller blades of the furnace blower to promote the circulation and uniform heating of the furnace atmosphere, thereby ensuring the quality of the annealing process. During long-term operation, due to the high temperature inside the annealing furnace and the dust generated by the materials to be treated and the furnace lining materials, this dust inevitably adheres to the surface of the impeller blades, resulting in a large accumulation of dust. The accumulation of dust can significantly change the original aerodynamic shape of the blades, thereby affecting the working efficiency of the impeller, reducing the air volume of the blower, and increasing energy loss. Over time, it can also cause dynamic imbalance of the impeller, generating vibration, accelerating the wear of bearings and related transmission components, and even leading to equipment failure. Frequent shutdowns for manual cleaning not only consume a lot of time and increase maintenance costs, but also seriously affect production efficiency.

[0003] Furthermore, in actual operation of bell-type annealing furnaces, especially when placing or removing heavy materials, the entire furnace structure, particularly the bottom support structure, will be subjected to significant instantaneous impacts and pressures. The base structure lacks an effective buffering mechanism, and long-term exposure to such impacts will lead to structural fatigue, increasing the risk of cracking or damage to support components and shortening the service life of the equipment. Based on the above situation, there is room for improvement in the impeller blade structure of existing bell-type annealing furnaces in terms of preventing ash accumulation and base vibration reduction. Existing technologies rely on periodic manual cleaning to solve the problem of ash accumulation on the blades, which is inefficient and costly. In terms of base vibration reduction, there is also a lack of integrated and efficient solutions.

[0004] Therefore, this utility model proposes a hood-type annealing furnace impeller blade structure to prevent ash accumulation, thereby addressing the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of dust accumulation on the impeller blade structure of the hood-type annealing furnace, which is difficult to clean automatically, and the lack of a buffer mechanism on the base when subjected to pressure, which leads to impact damage to the support, this utility model aims to provide a dust accumulation-proof hood-type annealing furnace impeller blade structure that can effectively solve the above problems.

[0006] This utility model provides a hood-type annealing furnace impeller blade structure for preventing ash accumulation, comprising: a base, a rotating wheel rotatably disposed on the top of the base, fan blades fixedly connected to the inner wall of the rotating wheel, and a cleaning mechanism.

[0007] Furthermore, the cleaning mechanism includes a coupling, a transmission block, and a steel ball. The coupling is fixedly connected to the right side of the fan blade, the transmission block is rotatably connected to the inner wall of the coupling, and the steel ball is fixedly connected to the bottom of the transmission block.

[0008] Preferably, the cleaning mechanism further includes a guide plate and a collection trough, the guide plate is fixedly connected to the bottom right side of the fan blade, and the collection trough is provided on the top of the base.

[0009] Preferably, the guide port of the guide plate is directed to the top of the collection tank.

[0010] Preferably, the impeller blade structure of the ash-proof hood-type annealing furnace further includes a shock-absorbing mechanism, which is disposed at the bottom of the base.

[0011] Preferably, the shock absorption mechanism includes a limiting column, a fixing column, and a lifting leg. The limiting column is fixedly connected to the bottom of the base, and the fixing column is used to fix it at a designated position below the base.

[0012] Preferably, the lifting leg is slidably connected to the inner wall of the limiting post and the fixed post.

[0013] Preferably, the shock absorption mechanism further includes a spring, which is fixedly connected to the inner wall of the limiting post, and the bottom of the spring is fixedly connected to the top of the fixed post.

[0014] Preferably, the lifting leg encloses the spring inside.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem of dust accumulation on the surface of impeller blades in existing bell-type annealing furnaces after long-term operation, which is difficult to clean automatically, by setting a cleaning mechanism consisting of a coupling, a transmission block, and steel balls on the impeller blades, and cooperating with the guide plate at the bottom of the blades and the collection groove on the base. It achieves the effect of automatically knocking off the dust by the steel balls driven by gravity when the impeller stops rotating, and guiding the dust to slide into the collection groove for centralized collection through the guide plate, effectively keeping the blades clean and ensuring the operating efficiency of the equipment.

[0017] 2. This utility model solves the problem in the prior art that the base lacks effective buffer protection when subjected to external pressure or impact, leading to the breakage or damage of the bottom support structure. It achieves the effect of using the elastic deformation of the spring to absorb the impact force and provide a certain buffer space for the base, thereby significantly improving the load-bearing stability and service life of the overall equipment structure.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 6 This utility model provides a dust-proof impeller blade structure for a hood-type annealing furnace, which aims to solve the problem that dust accumulates on the surface of the fan blade 201 in the existing hood-type annealing furnace impeller blade structure, and that the base 1 lacks an effective buffering mechanism when subjected to pressure, resulting in the support being damaged by impact.

[0029] Please refer to Figure 1 and Figure 2 The impeller blade structure of the hood-type annealing furnace for preventing ash accumulation includes a base 1 and a rotating wheel 4 rotatably mounted on top of the base 1. The base 1 serves as the main support base for the entire equipment, bearing the upper rotating mechanism and the lower shock-absorbing mechanism 3. The rotating wheel 4 is used to drive the fan blades 201 to generate wind power when rotating, thereby realizing gas circulation inside the annealing furnace.

[0030] Please refer to Figure 2 , Figure 3 and Figure 4 The cleaning mechanism 2 includes a coupling 202, a transmission block 203, a steel ball 204, a guide plate 205, and a collection trough 206.

[0031] The coupling 202 is fixedly connected to the right side of the fan blade 201, and the transmission block 203 is rotatably connected to the inner wall of the coupling 202. This connection method allows the transmission block 203 to swing freely under the action of the center of gravity. The steel ball 204 is fixedly connected to the bottom of the transmission block 203, forming a component with specific mass and impact capability. When the wheel 4 rotates at high speed driven by the external motor, the fan blade 201 rotates accordingly. The transmission block 203 rotates backward and unfolds under the action of centrifugal force, so that the bottom steel ball 204 is away from the surface of the fan blade 201 and does not come into contact. Once the fan blade 201 stops rotating, the transmission block 203 will fall rapidly under its own gravity, driving the steel ball 204 fixed at the bottom of the transmission block 203 to strike the surface of the fan blade 201. The vibration generated by the striking effectively removes the dust attached to the fan blade 201.

[0032] Meanwhile, the guide plate 205 is fixedly connected to the bottom right side of the fan blade 201, and the collection trough 206 is set on the top of the base 1. The guide port of the guide plate 205 guides the top of the collection trough 206. When the steel ball 204 knocks on the fan blade 201 and causes dust to fall off, the dust will fall to the top of the guide plate 205. Through the guiding action of the guide plate 205, the dust is guided and slides into the collection trough 206, realizing the centralized collection of dust and facilitating subsequent cleaning. This series of structures work together to effectively solve the problem of dust accumulation on the fan blade 201 and improve the operating efficiency and cleanliness of the bell-type annealing furnace.

[0033] As a preferred embodiment, please refer to Figure 1 , Figure 5 and Figure 6The impeller blade structure of the hood-type annealing furnace for preventing ash accumulation also includes a shock-absorbing mechanism 3. The shock-absorbing mechanism 3 is located at the bottom of the base 1. The shock-absorbing mechanism 3 includes a limiting column 301, a fixing column 302, and a lifting leg 303. The limiting column 301 is fixedly connected to the bottom of the base 1, and the fixing column 302 is used to fix it at a designated position below the base 1. As a moving part of the shock-absorbing mechanism 3, the lifting leg 303 is slidably connected to the inner wall of the limiting column 301 and the fixing column 302. In order to provide buffering force, the shock-absorbing mechanism 3 also includes a spring 304. The spring 304 is fixedly connected to the inner wall of the limiting column 301, and the bottom of the spring 304 is fixedly connected to the top of the fixing column 302. As a protective structure, the lifting leg 303 wraps the spring 304 inside.

[0034] Working Principle: During annealing, a rotating wheel 4 is installed on the top of the base 1. Multiple fan blades 201 are fixedly connected to the inner wall of the rotating wheel 4. When the external motor is started, driving the rotating wheel 4 to rotate, the multiple fan blades 201 rotate accordingly, generating airflow. Since couplings 202 are fixedly connected to the right sides of each fan blade 201, and transmission blocks 203 are rotatably connected to the inner walls of the couplings 202, and multiple steel balls 204 are fixedly connected to the bottom of the transmission blocks 203, the transmission blocks 203 rotate and unfold backward through the couplings 202 when the fan blades 201 rotate. When the fan blades 201 stop rotating, the transmission blocks 203... 03 Due to gravity, the steel ball 204 falls and strikes the fan blade 201, thereby removing the dust attached to the surface of the fan blade 201. Since the bottom right side of the fan blade 201 is fixedly connected to the guide plate 205, and the top of the base 1 is provided with a collection groove 206, and the guide opening of the guide plate 205 guides the top of the collection groove 206, after the steel ball 204 strikes the fan blade 201, the dust falling from the surface of the fan blade 201 will fall to the top of the guide plate 205, and through the guidance of the guide plate 205, the dust will slide into the collection groove 206, thereby collecting the dust. The cleaning mechanism 2 collects the dust attached to the fan blade 201.

[0035] Furthermore, when placing materials, since multiple limiting posts 301 are fixedly connected to the bottom of the base 1, and the fixing posts 302 are used to fix the base 1 at a designated position below it, and the multiple limiting posts 301 and the inner wall of the fixing posts 302 are slidably connected to the lifting legs 303, after the multiple fixing posts 302 are fixed at the designated position, the base 1 can move up and down slightly through the lifting legs 303, so that the base 1 has a certain buffer space. Since the inner wall of the limiting posts 301 is fixedly connected to the springs 304, and the bottom of the springs 304 is fixedly connected to the top of the fixing posts 302, and the lifting legs 303 wrap the springs 304 inside, when the materials are placed on top of the base 1, the base 1 is pressed down a certain distance. During this process, the multiple springs 304 offset part of the pressure generated, thereby preventing the support at the bottom of the base 1 from breaking due to excessive pressure. The shock absorption mechanism 3 relieves the pressure generated, so that the equipment will not be unable to support itself due to excessive pressure.
