Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, and in particular to a support device for incinerator inlet and outlet valves. Background Technology

[0002] Regenerative thermal oxidizers (RTOs) are key equipment for the efficient treatment of industrial organic waste gases. They recover heat generated during combustion through a regenerator, achieving efficient energy utilization and compliant emissions. They are widely used in industries such as chemical and coating. Their core operation relies on the precise switching of inlet and outlet valves to ensure the orderly alternation of waste gas intake, heat storage, heat exchange, and exhaust. Therefore, the stable operation of these valves directly affects the incinerator's processing efficiency and safety performance. However, in actual operation, the support structure of the inlet and outlet valves faces multiple severe challenges. On the one hand, the frequent switching between high and low temperature flue gas during incinerator operation causes drastic thermal expansion and contraction of the support structure, resulting in periodic stress changes. On the other hand, the irregular thrust and tension generated during valve opening and closing further exacerbate the load on the support structure.

[0003] In existing technologies, valve research for regenerative thermal oxidizers (RTOs) primarily focuses on optimizing the valve's switching function. For example, Chinese patent CN220118649U discloses a gas switching valve for RTOs. This valve mainly uses a single-stroke cylinder to drive a connecting rod, baffle, and spring assembly, enabling a single valve to control two exhaust ports, effectively solving the problem of excessive costs caused by multiple valve control. Although this valve can improve its structural strength through components such as support seats, support frames, and mounting plates, this technology fails to consider the stability of the support structure under thermal stress and external forces.

[0004] Currently, conventional support structures are highly susceptible to breakage at their connection points with the furnace body due to the aforementioned multiple factors. Breakage of the support structure directly leads to valve failure, preventing the switching of exhaust gas flow direction and resulting in incomplete combustion and excessive emissions. In more serious cases, the mixture of unburned combustible gases may reach explosive limits, triggering furnace explosions and other major safety accidents, severely threatening production and environmental safety. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as poor stability of the support structure, which can easily lead to valve failure and affect environmental safety, and to provide a support device for the inlet and outlet valves of an incinerator.

[0006] This utility model is achieved through the following technical solution: a support device for an incinerator inlet and outlet valve, comprising a support column arranged on one side of the inlet and outlet valve, a guide pulley provided at the top of the support column, the bottom of the support column being able to connect with the mounting surface A of the furnace body, and the guide pulley being able to slide with the transmission rod of the inlet and outlet valve; a front positioning plate provided on the front side of the support column, a rear positioning plate provided on the rear side of the support column, and the front and rear positioning plates being able to connect with the mounting surfaces B and C of the furnace body; balancing braces provided on the left and right sides of the support column, the top of the balancing braces being connected to the support column, and a side positioning plate provided at the bottom of the balancing braces, and the side positioning plate being able to connect with the mounting surface A of the furnace body.

[0007] As the core load-bearing component, the support column is fixed to the furnace body shell by connecting its bottom to the mounting surface. The guide pulley at the top slides with the transmission rod of the inlet and outlet valves, providing precise guidance for the reciprocating motion of the transmission rod and preventing it from deviating or jamming. The front and rear positioning plates further fix the support column to the furnace shell from the front and rear directions, counteracting the front and rear thrust and pull forces generated when the valves are opened and closed. The balancing diagonal braces on the left and right sides are connected to the support column at the top and to the furnace shell at the bottom via the side positioning plates, forming a triangular stable structure that effectively resists lateral forces and prevents the support column from swaying left and right.

[0008] This device, through the aforementioned multi-directional positioning and support design, can enhance overall strength and stability, withstand the reaction force of the transmission rod movement and the stress generated by alternating hot and cold temperatures, prevent the support structure from breaking, and improve the reliability of valve operation.

[0009] A further improvement of this utility model is that a pulley base is provided on the top of the supporting column, a pulley bracket is fixed on the pulley base, and the guide pulley is installed on the pulley bracket.

[0010] A further improvement of this utility model is that reinforcing plates are respectively provided between the two sides of the pulley bracket and the pulley base, and the reinforcing plates are connected together with the pulley base and the pulley bracket.

[0011] A further improvement of this utility model is that the guide pulley is provided with a guide groove corresponding to the transmission rod, and the transmission rod is slidably disposed inside the guide groove.

[0012] A further improvement of this utility model is that the guide groove has a U-shaped structure.

[0013] A further improvement of this utility model is that a reinforcing diagonal brace is provided between the supporting column and the front positioning plate, the top of the reinforcing diagonal brace is connected to the top of the supporting column, and the bottom of the reinforcing diagonal brace is connected to the front positioning plate.

[0014] A further improvement of this utility model is that the top of the balancing brace is connected to the middle of the supporting column.

[0015] A further improvement of this utility model is that both the front positioning plate and the rear positioning plate can be embedded in the mounting surface B and mounting surface C of the furnace body.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] 1. The main support of this device adopts a combination of support columns and front and rear positioning plates, along with balancing diagonal braces on the left and right sides to form a three-dimensional fixed structure. This effectively resists the forward and backward thrust, lateral forces, and stresses caused by alternating hot and cold temperatures generated during valve opening and closing, solving the problem of easy breakage in traditional support structures. Simultaneously, the precise cooperation between the top guide pulley and the transmission rod, along with the groove design to prevent transmission rod misalignment, ensures smooth valve switching and avoids interruptions in waste gas treatment due to mechanical jamming, significantly improving the reliability of the regenerative thermal oxidizer operation.

[0018] 2. This device focuses on improving the durability of the support structure. Through detailed designs such as embedded positioning plates and reinforced diagonal braces, the connection strength with the furnace body is strengthened, which can extend the service life of the support device, reduce maintenance costs and downtime risks caused by structural wear, and ensure the long-term stable operation of the incinerator from the hardware foundation.

[0019] 3. This device, through its stable support structure, avoids turbulent waste gas flow caused by valve failure, preventing the accumulation of unburned combustible gas and the resulting explosion hazards. The reliable cooperation between the transmission rod and the guide pulley ensures the precision of intake and exhaust switching, guaranteeing complete combustion of waste gas to meet emission standards. Furthermore, the rigid connections and distributed stress design of each component reduce equipment damage and personnel safety hazards caused by structural fractures, comprehensively improving the safety performance of the regenerative thermal oxidizer.

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

[0027] Now refer to Figures 1-3 The following is a description of a specific embodiment of the present invention: A support device for an incinerator inlet and outlet valve of the present invention includes a support column 1, which is arranged on one side of the inlet and outlet valve 12. A guide pulley 7 is provided at the top of the support column 1, and the bottom of the support column 1 can be welded to the mounting surface A13 of the furnace body. The guide pulley 7 can be slidably connected to the transmission rod 11 of the inlet and outlet valve 12. A front positioning plate 3 is provided on the front side of the support column 1, and a rear positioning plate 4 is provided on the rear side of the support column 1. The front positioning plate 3 and the rear positioning plate 4 can be connected to the mounting surfaces B14 and C15 of the furnace body. Balance braces 5 are respectively provided on the left and right sides of the support column 1. The top of the balance brace 5 is connected to the support column 1, and a side positioning plate 6 is provided at the bottom of the balance brace 5. The side positioning plate 6 can be welded to or embedded in the mounting surface A13 of the furnace body.

[0028] As the core load-bearing component, the support column 1 is fixed to the base by connecting its bottom to the mounting surface of the furnace body shell. The guide pulley 7 at its top slides with the transmission rod 11 of the inlet and outlet valve 12, providing precise guidance for the reciprocating motion of the transmission rod 11 and preventing the transmission rod 11 from deviating or getting stuck. The front positioning plate 3 and the rear positioning plate 4 further fix the support column 1 to the mounting surface of the furnace body from the front and rear directions, counteracting the front and rear thrust and pull generated when the valve is opened and closed. The balance diagonal braces 5 on the left and right sides are connected to the support column 1 at the top and to the furnace shell at the bottom through the side positioning plate 6, forming a triangular stable structure that effectively resists lateral forces and prevents the support column 1 from swaying left and right.

[0029] This device, through the aforementioned multi-directional positioning and support design, can enhance overall strength and stability, withstand the reaction force of the transmission rod 11 movement and the stress generated by alternating hot and cold temperatures, prevent the support structure from breaking, and improve the reliability of valve operation.

[0030] Specifically, refer to Figure 1 and Figure 2 The top of the support column 1 is provided with a pulley base 8, a pulley bracket 9 is fixed on the pulley base 8, and the guide pulley 7 is installed on the pulley bracket 9.

[0031] The pulley base 8 at the top of the support column 1 provides an installation base for the pulley bracket 9. The pulley bracket 9 directly fixes the guide pulley 7. Through the hierarchical connection between the base and the bracket, the guide pulley 7 and the support column 1 form a rigid whole.

[0032] The above design enhances the installation stability of the guide pulley 7, preventing it from loosening or shifting under long-term sliding friction of the transmission rod 11, ensuring guiding accuracy, and extending the service life of the device.

[0033] Specifically, refer to Figure 2 and Figure 3 The guide pulley 7 is provided with a guide groove 701 corresponding to the transmission rod 11, and the transmission rod 11 is slidably disposed inside the guide groove 701.

[0034] The guide groove 701 on the guide pulley 7 matches the shape of the transmission rod 11. When the transmission rod 11 slides in the groove, the groove forms a radial constraint on the transmission rod 11, limiting its vertical or horizontal displacement.

[0035] The device, through the above design, can prevent the transmission rod 11 from disengaging from the guide pulley 7, ensuring its precise movement trajectory, reducing jamming during valve switching, and improving the smoothness of the intake and exhaust process.

[0036] Specifically, refer to Figure 1A reinforcing brace 2 is provided between the supporting column 1 and the front positioning plate 3. The top of the reinforcing brace 2 is connected to the top of the supporting column 1, and the bottom of the reinforcing brace 2 is connected to the front positioning plate 3.

[0037] The reinforcing diagonal brace 2 connects the top of the support column 1 to the front positioning plate 3, forming a triangular stable structure with the support column 1 and the front positioning plate 3, specifically resisting the forward thrust when the valve is opened and closed.

[0038] Through the above design, this device can specifically enhance the thrust resistance of the support column 1, prevent it from tilting forward or breaking at the root due to excessive force at the front end, and improve the adaptability of this device to complex working conditions.

[0039] In one embodiment, reference Figure 1 and Figure 2 A reinforcing plate 10 is provided on both sides of the pulley bracket 9 and between the pulley base 8, and the reinforcing plate 10 is connected to the pulley base 8 and the pulley bracket 9.

[0040] The reinforcing plates 10 on both sides of the pulley bracket 9 and the pulley base 8 form a triangular support structure, which disperses the lateral force of the transmission rod 11 borne by the pulley bracket 9 to the pulley base 8, reducing stress concentration at the connection between the bracket and the base.

[0041] The device, through the above design, can improve the deformation resistance of the pulley assembly, prevent the bracket from bending or breaking due to long-term stress, and ensure that the guide pulley 7 is always in a stable working position.

[0042] In one embodiment, reference Figure 3 The guide groove 701 has a U-shaped structure.

[0043] The U-shaped guide groove 701 has an open side and a closed bottom, which facilitates the installation and disassembly of the transmission rod 11 and can form an all-round wrapping constraint on the transmission rod 11 through the side walls and the bottom.

[0044] Through the above design, this device can enhance the limiting effect on the transmission rod 11 while ensuring ease of installation, adapt to the sliding requirements of transmission rods 11 with different diameters, and improve the versatility of this device.

[0045] In one embodiment, reference Figure 2 The top of the balancing brace 5 is connected to the middle of the supporting column 1.

[0046] The top of the balancing brace 5 is connected to the middle of the support column 1, so that the supporting force of the brace acts on the middle section of the column where the force is concentrated, and the bending moment generated by the lateral force in the middle of the column is more efficiently dispersed.

[0047] Through the above design, this device can optimize the force transmission path, reduce the risk of deformation in the middle of the supporting column 1, and further improve the overall structure's resistance to tilting.

[0048] In one embodiment, both the front positioning plate 3 and the rear positioning plate 4 can be embedded in the mounting surface A13 of the furnace body.

[0049] The front positioning plate 3 and the rear positioning plate 4 are embedded in the mounting surface A13 of the furnace body, so that the positioning plate and the mounting surface form an embedded connection, with a larger contact area and higher connection strength, while also ensuring the sealing of the mounting surface.

[0050] The above design enhances the connection stability between the positioning plate and the mounting surface, preventing it from loosening under long-term stress or vibration, providing a stable foundation for the support column 1, and improving the overall fatigue resistance of the device.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
