Description

Technical Field

[0001] This utility model relates to the field of mechanical feeding technology, specifically a waste incinerator grate feeding control system. Background Technology

[0002] Waste enters the inclined grate through the feed hopper. The grate is divided into a drying zone, a combustion zone, and a burnout zone. Due to the staggered movement between the grates, the waste is pushed downwards, allowing it to pass through the various zones on the grate in sequence. Combustion air enters from the bottom of the grate and mixes with the waste. High-temperature flue gas generates hot steam through the boiler's heating surface, while the flue gas is also cooled. Finally, the flue gas is discharged after being treated by a flue gas treatment device.

[0003] Mechanical reciprocating grate furnaces are commonly used combustion equipment in fields such as waste incineration and industrial solid waste treatment. They achieve the turning, pushing and combustion of materials through the reciprocating motion of the grate. The reciprocating motion of the grate is mainly driven by mechanical force to propel the materials forward. The distribution and turning degree of materials on the grate are limited by the structure, which can easily lead to local accumulation that is too thick or too thin. Areas with excessively thick accumulation have insufficient oxygen supply, which can easily lead to incomplete combustion, such as the generation of carbon monoxide and soot, reducing combustion efficiency. Areas with excessively thin accumulation may experience accelerated wear of the grate bars due to excessively high temperatures. Summary of the Invention

[0015] Please see Figures 1-4 In this embodiment of the invention, a waste incinerator grate feeding control system includes a furnace body 1, a pusher 2, and a combustion chamber 6. The furnace body 1 has a discharge port, through which waste is pushed into the combustion chamber 6 by the pusher 2. A waste shredder 3 is positioned above the discharge port. The furnace body 1 contains a static grate and a dynamic grate. The dynamic grate is mounted on a grate base 5, which is driven by a hydraulic pusher 11. Static grates are positioned between the dynamic grates and are fixed to the furnace body 1. Waste is fermented in a waste storage area, and a mechanical gripper grabs the waste from the storage area and feeds it into the waste shredder 3. The waste shredder 3 shreds the waste into fragments, which facilitates grate advancement. The waste fragments enter through the discharge port and are pushed into the combustion chamber 6 by the pusher 2. The dynamic grate has a travel distance of five centimeters, and the distance from the end of the dynamic grate to the end of the static grate is also five centimeters. Each movement of the dynamic grate... The stroke of the grate can completely push the waste on the static grate to the next row of dynamic grates. As the next row of dynamic grates extends outward, the waste falls onto the newly extended portion. During the retraction of the dynamic grate, the waste on the dynamic grate is pushed onto the next layer of static grate by the obstruction of the static grate, thus completing the waste transportation. This reduces the travel distance of the dynamic grate and increases the number of dynamic and static grates. Each time, the material on the previous grate can be pushed completely and fall onto the next layer of grate, thus preventing uneven waste accumulation. It also increases the frequency of waste tumbling and pushing, ensuring complete combustion of the waste. The dynamic and static grates are also equipped with oxygen blowing holes, and oxygen supply lines are installed at the bottom of the dynamic and static grates. Oxygen enters the cavity between the grate base 5 and the dynamic and static grates through the oxygen supply lines, and is then blown out from the gaps in the structure and through the oxygen blowing holes to aid combustion.

[0016] In a preferred embodiment, the grate base 5 and the furnace body 1 are movably installed via a sliding rail component. The sliding rail component includes a sliding seat 7 and a fixed seat 9. The sliding seat 7 is provided on one side of the combustion chamber 6, and the fixed seat 9 is provided inside the furnace body 1. The sliding seat 7 and the fixed seat 9 are movably connected. The sliding seat 7 includes a horizontal seat 701, a bracket 702, and a steel rail 703. The horizontal seat 701 is fixed to the grate base 5 by multiple brackets 702, and the horizontal seat 701 is kept horizontal. Multiple steel rails 703 are installed at the bottom of the horizontal seat 701. The fixed seat 9 includes a water platform 901, a roller seat 902, and a roller assembly 903. The water platform 901 is installed inside the furnace body 1 and located below the steel rails 703. Multiple roller seats 902 are installed on the top of the grate. A rotatable roller assembly 903 located below the rail 703 is installed between two adjacent roller seats 902. The rail 703 is provided with a sliding groove. The roller assembly 903 rolls in the sliding groove to reduce friction during the movement of the dynamic grate. The number of dynamic grates on the grate base 5 increases, and the weight also increases significantly. In the past, when the grate was installed by means of a sliding rail, the ambient temperature also increased when the temperature inside the furnace was high. The sliding rail expanded due to heat, and the friction increased. At the same time, impurities in the environment would also enter the sliding rail and affect its working stability. Therefore, this application can effectively reduce the sliding resistance and friction caused by thermal expansion by using the rail 703 and the roller assembly 903. At the same time, it has a strong load-bearing capacity and stable operation.

[0017] In a preferred embodiment, the grate base 5 and the hydraulic push rod 11 are connected by a transmission assembly; The transmission assembly includes a bearing housing 8, a drive shaft 10, and a crank arm 12. The telescopic end of the hydraulic push rod 11 is rotatably connected to the crank arm 12, and the other end of the crank arm 12 is rotatably connected to the drive shaft 10. The drive shaft 10 is rotatably connected to the grate base 5 through the bearing housing 8. The hydraulic push rod 11 is not suitable for operation in high-temperature environments. The hydraulic push rod 11 needs to be installed outside the furnace, and the power is transmitted to the grate base 5 through the transmission assembly to perform the operation.

[0018] In a preferred embodiment, the crank arm 12 is curved, and the bend of the crank arm 12 is rotatably connected to the carrier through a bearing. The connection end of the crank arm 12 and the hydraulic push rod 11 is the power arm, and the connection end of the crank arm 12 and the drive shaft 10 is the resistance arm. The function of the crank arm 12 is to change the power direction of the hydraulic push rod 11 to drive the grate base 5 to move horizontally.

[0019] In a preferred embodiment, the static grate and the dynamic grate have the same structure, consisting of a grate frame and a grate liner 13. The grate liner 13 is installed on the outside of the grate frame, and the grate frame of the static grate is fixed to the grate base 5 by the grate seat 4.
