Description

Technical Field

[0001] This utility model relates to the technical field of waste incineration equipment, and in particular to an adjustable waste incinerator grate ventilation device. Background Technology

[0002] In the field of waste incineration, grate ventilation is a core parameter affecting the efficiency and effectiveness of waste combustion. Sufficient and reasonable ventilation can provide the necessary oxygen for waste combustion, accelerate the oxidation reaction process, and enable waste to burn completely, thereby improving energy conversion efficiency. At the same time, scientific ventilation control can effectively suppress the emission of pollutants such as carbon monoxide and dioxins produced by incomplete combustion, reducing the risk of environmental pollution.

[0003] However, current waste incinerator grate ventilation control devices generally suffer from technical bottlenecks. From a performance perspective, most traditional devices employ a crude control model, equipped only with simple mechanical valves or fixed-gear adjustment structures, failing to accurately adapt to the characteristics of different types of waste. For example, when processing high-humidity municipal solid waste, these devices struggle to dynamically increase ventilation to compensate for the oxygen consumption during combustion due to moisture evaporation; conversely, when dealing with dry industrial waste, they cannot promptly reduce airflow, resulting in excessive air carrying away significant heat energy and reducing incineration efficiency.

[0004] In terms of equipment reliability, some devices are prone to problems such as component jamming and wear in high-temperature and high-dust incineration environments due to their complex structural design. This not only frequently affects the normal operation of the incinerator, but also incurs considerable costs for each repair, significantly increasing the operational burden on waste treatment companies.

[0005] Therefore, this application provides an adjustable grate ventilation device for waste incinerators to meet the requirements. Utility Model Content

[0006] The purpose of this application is to provide an adjustable grate ventilation device for a waste incinerator, which, through optimized structural design, enables flexible adjustment of ventilation volume, improves waste incineration efficiency, and reduces maintenance costs.

[0007] To achieve the above objectives, this application provides the following technical solution: an adjustable grate ventilation device for a waste incinerator, comprising a primary air chamber, a synchronous shaft seat, and an adjustment mechanism.

[0008] The bottom of the primary air chamber is provided with an air inlet for introducing primary air; the top of the primary air chamber is provided with an adjustment chamber, the front outer wall of the adjustment chamber is provided with an adjustment motor, the adjustment chamber is provided with an adjustment mechanism, and the adjustment motor is used to drive the adjustment mechanism to adjust the ventilation volume.

[0009] There are four sets of synchronous shaft seats arranged symmetrically. Two sets of synchronous shaft seats are vertically slidably connected to the front and rear inner walls of the adjustment chamber, providing connection and guidance for the components in the adjustment mechanism.

[0010] The adjustment mechanism further includes an upper blade, a lower blade, and a drive shaft. Multiple sets of upper and lower blades are present, with the upper blades evenly arranged and symmetrically positioned within the adjustment chamber. Each set of upper blades is hinged to a set of lower blades via a connecting shaft. The front and rear sides of the upper blades are hinged to the upper synchronous shaft seat, and the front and rear sides of the lower blades are hinged to the lower synchronous shaft seat. The drive shaft is rotatably connected within the adjustment chamber and driven by the adjustment motor. The drive shaft drives the connecting shafts on both sides to move synchronously in opposite directions, thereby opening and closing the upper and lower blades and adjusting the ventilation volume.

[0011] Furthermore, a through groove is provided in the middle of the connection between the upper blade and the lower blade, and a portion of the connecting shaft is exposed in the through groove. The exposed portions of the connecting shaft on the same side are all hinged to the synchronizing rods. Symmetrical swing arms are provided on the drive shaft, and the ends of the two sets of synchronizing rods are respectively hinged to the swing arms via connecting rods. This structure allows the drive shaft to drive the connecting shaft to move synchronously in opposite directions through the linkage of the swing arms, connecting rods, and synchronizing rods, ensuring coordinated movement of the upper and lower blades.

[0012] Furthermore, the front and rear inner walls of the adjusting chamber are symmetrically provided with limiting strips and guide strips. The limiting strips are located in the middle, and multiple sets of guide strips are symmetrically arranged. The synchronous shaft seat is provided with limiting grooves and guide grooves. The limiting grooves are adapted to the limiting strips, and the guide grooves are adapted to the guide strips. Through the cooperation of the limiting strips and guide strips with the corresponding grooves on the synchronous shaft seat, the stability and accuracy of the synchronous shaft seat during vertical sliding can be ensured, preventing it from shifting or shaking.

[0013] Furthermore, the upper blade is hinged to the synchronous shaft seat via an upper synchronous shaft, and the lower blade is hinged to the synchronous shaft seat via a lower synchronous shaft. The upper blade is bent along the upper synchronous shaft, and the lower blade is bent along the lower synchronous shaft. This bending design enhances the structural strength of the upper and lower blades, helps to change the airflow direction, makes ventilation more uniform, and can reduce or even eliminate gaps between the blades during folding.

[0014] Furthermore, the top of the regulating chamber is provided with an air distribution grille, and the air distribution grille is provided with an air outlet trough. The air outlet trough is uniformly provided with grid plates, all of which are vertically arranged. The arrangement of the air distribution grille and grid plates enables the regulated airflow to be evenly distributed, further improving the uniformity of ventilation on the grate surface.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. Precise adjustment of ventilation volume: By adjusting the motor-driven drive shaft, the upper and lower blades can be opened and closed, which can realize stepless adjustment of ventilation volume. It can precisely control the ventilation volume according to the combustion requirements of different wastes, thereby improving the waste incineration efficiency.

[0017] 2. Stable and reliable structure: The synchronous shaft seat cooperates with the limit strip and guide strip on the inner wall of the regulating chamber to ensure the smooth movement of the regulating mechanism, reduce wear between components, reduce maintenance costs, and extend the service life of the device.

[0018] 3. Optimized ventilation: The bending design of the upper and lower blades and the setting of the air distribution grille enable the airflow to be evenly distributed on the surface of the grate, which helps the waste to burn completely and reduces the emission of pollutants.

[0030] There are four sets of synchronous shaft seats 3 arranged symmetrically, and two sets of synchronous shaft seats 3 are vertically slidably connected to the front and rear inner walls of the regulating chamber 10.

[0031] The adjustment mechanism also includes an upper blade 4, a lower blade 5, and a drive shaft 6. There are ten sets of upper blades 4 and lower blades 5. The upper blades 4 are evenly arranged and symmetrically set in the adjustment chamber 10. Each set of upper blades 4 is hinged to a set of lower blades 5 through a connecting shaft 9. The front and rear sides of the upper blades 4 are hinged to the upper synchronous shaft seat 3, and the front and rear sides of the lower blades 5 are hinged to the lower synchronous shaft seat 3. The drive shaft 6 is rotatably connected in the adjustment chamber 10 and driven by the adjustment motor 11. The drive shaft 6 can drive the connecting shafts 9 on the left and right sides to move synchronously in opposite directions.

[0032] As one implementation method in this embodiment, to ensure the synchronous movement of the upper blade 4 and the lower blade 5, such as... Figures 4 to 6 As shown, a through groove is provided in the middle of the connection between the upper blade plate 4 and the lower blade plate 5. Part of the connecting shaft 9 is exposed in the through groove. The exposed parts of the connecting shaft 9 on the same side are all hinged to the synchronizing rod 8. The drive shaft 6 is symmetrically provided with swing arms 60. The ends of the two sets of synchronizing rods 8 are respectively hinged to the swing arms 60 through the connecting rod 7.

[0033] As one implementation method in this embodiment, to improve the stability of the synchronous shaft support 3 during movement, such as... Figures 3 to 5 As shown, the front and rear inner walls of the regulating chamber 10 are symmetrically provided with limiting strips 12 and guide strips 13. The limiting strips 12 are located in the middle, and there are multiple sets of guide strips 13 arranged symmetrically. The synchronous shaft seat 3 is provided with limiting grooves 30 and guide grooves 31. The limiting grooves 30 are adapted to the limiting strips 12, and the guide grooves 31 are adapted to the guide strips 13.

[0034] As one implementation method in this embodiment, to enhance the airtightness of the upper blade 4 and lower blade 5 after adjustment, such as... Figures 3 to 6 As shown, the upper blade 4 is hinged to the synchronous shaft seat 3 via the upper synchronous shaft 40, and the lower blade 5 is hinged to the synchronous shaft seat 3 via the lower synchronous shaft 50. The upper blade 4 is bent along the upper synchronous shaft 40, and the lower blade 5 is bent along the lower synchronous shaft 50.

[0035] As one implementation method in this embodiment, to improve the uniformity of airflow, such as Figure 1 , Figure 2 As shown, the top of the regulating chamber 10 is provided with an air distribution grille 2, the air distribution grille 2 is provided with an air outlet trough, and the air outlet trough is evenly provided with grid plates 20, all of which are vertically arranged.

[0036] The working principle of this utility model is as follows: In actual use, primary air enters through the air inlet at the bottom of the primary air chamber 1. The regulating motor 11 starts, driving the drive shaft 6 to rotate in the regulating chamber 10. The swing arm 60 on the drive shaft 6 pulls the synchronous rods 8 on both sides to move synchronously in opposite directions through the connecting rod 7. The synchronous rods 8 drive the connecting shaft 9 to move, causing the upper blade 4 and the lower blade 5 to swing around their respective hinge points with the synchronous shaft seat 3, thereby changing the cross-sectional area of ​​the ventilation channel and realizing the adjustment of the ventilation volume.

[0037] When increased ventilation is required, the regulating motor 11 drives the drive shaft 6 to rotate, causing the upper blade 4 to swing upward and the lower blade 5 to swing downward. The cross-sectional area of ​​the ventilation channel between adjacent upper blades 4 and adjacent lower blades 5 increases, and the air volume increases. During this process, the upper synchronous shaft 40 and the lower synchronous shaft 50 drive the synchronous shaft seat 3 to move in opposite directions. Conversely, when decreased ventilation is required, the drive shaft 6 rotates in the opposite direction, and the upper blades 4 and lower blades 5 swing in opposite directions. The cross-sectional area of ​​the ventilation channel decreases, and the air volume decreases. During this process, the upper synchronous shaft 40 and the lower synchronous shaft 50 drive the synchronous shaft seat 3 to move towards each other.

[0038] During the vertical sliding process of the synchronous shaft seat 3, the limiting strip 12 cooperates with the limiting groove 30 to prevent the synchronous shaft seat 3 from shifting laterally; the guide strip 13 cooperates with the guide groove 31 to ensure that the synchronous shaft seat 3 slides smoothly and to ensure the accuracy of the adjustment mechanism's operation.

[0039] After being regulated, the airflow passes through the air distribution grid 2 at the top of the regulating chamber 10. The grid plate 20 on the air distribution grid 2 divides the airflow evenly, so that the airflow is evenly sent to the grate, providing stable and uniform ventilation conditions for waste incineration and improving the waste incineration effect.
