Description

Technical Field

[0001] This utility model relates to the field of chain grate boiler technology, and in particular to a chain grate boiler. Background Technology

[0002] The chain grate is the main component of the chain grate furnace. The fuel bed moves forward with the grate surface, and the fuel undergoes the entire process of preheating, drying, ignition, combustion, and burnout. Finally, the ash is discharged as the grate surface moves. The air required for combustion is introduced from the bottom up from the bottom of the grate.

[0003] Extensive research revealed that existing chain conveyors, due to the fixed distance between the discharge cylinder and the chain conveyor belt, cannot adjust the thickness of the fuel particles conveyed on the chain conveyor belt. If the fuel is too thick, incomplete combustion is likely to occur.

[0004] Therefore, it is necessary to provide a chain grate boiler to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a chain grate boiler, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a chain grate boiler, including a furnace body. An mounting frame is installed on the outer surface of the furnace body, with one end extending into the interior of the furnace body. A chain grate conveying mechanism is installed inside the mounting frame. A support rod is vertically installed on the top surface of the mounting frame, and a feed hopper is installed at the top of the support rod. A horizontal plate is installed on the outer surface of the feed hopper, and an electric push rod is vertically installed on the bottom surface of the horizontal plate. An installation plate is provided at the output end of the electric push rod. A rectangular corrugated cylinder is provided through the bottom of the feed hopper, and a discharge cylinder is provided through the bottom of the rectangular corrugated cylinder. Two installation plates are respectively fixedly connected to the discharge cylinder. By using a combination of mounting frame, support rod, feed hopper, mounting plate, horizontal plate, electric push rod, discharge cylinder, and rectangular corrugated cylinder, the distance between the discharge cylinder and the chain conveyor mechanism can be easily adjusted. This allows for adjustment of the thickness of the fuel particles conveyed on the chain conveyor mechanism, preventing incomplete combustion caused by excessive fuel accumulation. During adjustment, the electric push rod is activated, which moves the mounting plate up and down. As the mounting plate moves, the discharge cylinder causes the rectangular corrugated cylinder to extend and retract, thus adjusting the distance between the discharge cylinder and the chain conveyor mechanism. This method is simple to operate and improves the flexibility of equipment use.

[0007] Preferably, a limiting component is installed on the top surface of the mounting plate on one side of the electric push rod. A limiting sleeve is provided inside the limiting component, and a limiting rod is slidably inserted inside the limiting sleeve. The top end of the limiting rod is fixed to the bottom surface of the horizontal plate. By setting the limiting component, it is convenient to limit and support the rectangular corrugated cylinder, avoiding the compression of the inner wall of the rectangular corrugated cylinder by fuel particles during the fall, which would cause longitudinal changes in the rectangular corrugated cylinder. This facilitates the vertical expansion and contraction of the rectangular corrugated cylinder and improves its service life.

[0008] Preferably, a drive motor is installed on the outer surface of the feed hopper, and a main shaft is provided through the output end of the drive motor and extending through the surface of the feed hopper. Multiple stirring rods are installed on the circumferential side of the main shaft, and these stirring rods are equidistantly installed on the outer surface of the main shaft. A filter plate is installed inside the feed hopper below the main shaft. The coordinated use of the drive motor, main shaft, stirring rods, and filter plate facilitates the filtration of the particulate fuel fed into the feed hopper, preventing large fuel particles from entering the furnace and causing incomplete combustion. During operation, the drive motor is started, and then the drive motor drives the stirring rods to rotate via the main shaft, thereby mixing the particulate fuel inside the feed hopper. Small fuel particles are then filtered out by the filter plate, while large fuel particles remain in the feed hopper and can be removed later. This method is simple to operate.

[0009] Preferably, an igniter is installed on the outer surface of the furnace body, which facilitates the ignition of the furnace body.

[0010] Preferably, a slag discharge port is provided through the lower part of the furnace body surface to facilitate the discharge of ash and slag.

[0011] Preferably, the bottom of the furnace body is provided with support legs, and multiple support legs are provided. The multiple support legs are installed at equal intervals at the four corners of the bottom of the furnace body. By providing support legs, it is convenient to support the furnace body, thereby improving the stability of the furnace body during operation.

[0012] Preferably, a controller is installed on the outer surface of the furnace body, which facilitates the control of the electrical components inside the equipment.

[0013] Compared with related technologies, the chain grate boiler provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, this type of chain grate boiler, through the coordinated use of a mounting frame, support rod, feed hopper, mounting plate, horizontal plate, electric push rod, discharge cylinder, and rectangular corrugated cylinder, facilitates the adjustment of the distance between the discharge cylinder and the chain grate conveying mechanism. This allows for the adjustment of the thickness of the particulate fuel conveyed on the chain grate conveying mechanism, avoiding incomplete combustion caused by excessive fuel accumulation. During adjustment, the electric push rod is activated, which then moves the mounting plate up and down. During the up-and-down movement of the mounting plate, the discharge cylinder drives the rectangular corrugated cylinder to extend and retract, thereby adjusting the distance between the discharge cylinder and the chain grate conveying mechanism. This method is simple to operate and improves the flexibility of equipment use.

[0015] Compared with existing technologies, this type of chain grate boiler, by setting a limiting component, facilitates the limiting support of the rectangular corrugated cylinder, avoids the compression of the inner wall of the rectangular corrugated cylinder by fuel particles during the fall, and prevents longitudinal changes of the rectangular corrugated cylinder. This facilitates the vertical expansion and contraction of the rectangular corrugated cylinder and improves its service life.

[0016] Compared with existing technologies, this type of chain grate boiler, through the coordinated use of a drive motor, main shaft, stirring rod, and filter plate, facilitates the filtration of particulate fuel fed into the feed hopper, preventing large fuel particles from entering the furnace and causing incomplete combustion. During operation, the drive motor is started, and then the drive motor drives the stirring rod to rotate via the main shaft, thereby mixing the particulate fuel in the feed hopper. Small fuel particles are then filtered out by the filter plate, while large fuel particles remain in the feed hopper and can be removed later. This method is simple to operate.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1-4 A chain grate boiler includes a furnace body 1. A mounting frame 2 is installed on the outer surface of the furnace body 1, with one end extending into the interior of the furnace body 1. A chain grate conveying mechanism is installed inside the mounting frame 2. A support rod 4 is vertically installed on the top surface of the mounting frame 2, and a feed hopper 3 is installed at the top of the support rod 4. A horizontal plate is installed on the outer surface of the feed hopper 3, and an electric push rod 9 is vertically installed on the bottom surface of the horizontal plate. A mounting plate 10 is provided at the output end of the electric push rod 9. A rectangular corrugated cylinder 12 is provided through the bottom of the feed hopper 3, and a discharge cylinder 11 is provided through the bottom of the rectangular corrugated cylinder 12. Two mounting plates 10 are respectively fixedly connected to the discharge cylinder 11. The mounting frame 2 is used to... The coordinated use of the support rod 4, feed hopper 3, mounting plate 10, horizontal plate, electric push rod 9, discharge cylinder 11, and rectangular corrugated cylinder 12 facilitates the adjustment of the distance between the discharge cylinder 11 and the chain conveyor mechanism. This allows for the adjustment of the thickness of the fuel particles conveyed on the chain conveyor mechanism, preventing incomplete combustion due to excessive fuel accumulation. During adjustment, the electric push rod 9 is activated, which then moves the mounting plate 10 up and down. As the mounting plate 10 moves up and down, the discharge cylinder 11 drives the rectangular corrugated cylinder 12 to extend and retract, thereby adjusting the distance between the discharge cylinder 11 and the chain conveyor mechanism. This method is simple to operate and improves the flexibility of equipment use.

[0027] The working principle of the chain grate boiler provided by this utility model is as follows:

[0028] During adjustment, the electric push rod 9 is activated, which then drives the mounting plate 10 to move up and down. During this movement, the discharge cylinder 11 drives the rectangular corrugated cylinder 12 to extend and retract, thus adjusting the distance between the discharge cylinder 11 and the chain conveyor mechanism. This method is simple to operate and improves the flexibility of equipment use. The setting of a limiting component facilitates the limiting support of the rectangular corrugated cylinder 12, preventing fuel particles from squeezing the inner wall of the cylinder during its descent and causing longitudinal changes in the cylinder. This ensures the vertical extension and retraction of the rectangular corrugated cylinder 12, extending its service life. The system utilizes a drive motor 17, a main shaft 18, a stirring rod 15, and a filter plate 16 to facilitate the filtration of particulate fuel fed into the feed hopper 3. This prevents large fuel particles from entering the furnace body 1 and causing incomplete combustion. During operation, the drive motor 17 is started, and then the drive motor 17 drives the stirring rod 15 to rotate via the main shaft 18. This causes the stirring rod 15 to mix the particulate fuel inside the feed hopper 3. Small fuel particles are then filtered out by the filter plate 16, while large fuel particles remain in the feed hopper 3 and can be removed later. This method is simple to operate.

[0029] Compared with related technologies, the chain grate boiler provided by this utility model has the following beneficial effects:

[0030] By using the mounting frame 2, support rod 4, feed hopper 3, mounting plate 10, horizontal plate, electric push rod 9, discharge cylinder 11, and rectangular corrugated cylinder 12 in combination, the distance between the discharge cylinder 11 and the chain conveyor mechanism can be easily adjusted. This allows for adjustment of the thickness of the fuel particles conveyed on the chain conveyor mechanism, preventing incomplete combustion due to excessive fuel accumulation. During adjustment, the electric push rod 9 is activated, which then moves the mounting plate 10 up and down. During this movement, the discharge cylinder 11 drives the rectangular corrugated cylinder 12 to extend and retract, thus adjusting the distance between the discharge cylinder 11 and the chain conveyor mechanism. This method is simple to operate and improves the flexibility of equipment use. The inclusion of a limiting component facilitates the limiting support of the rectangular corrugated cylinder 12, preventing... During the descent of the fuel-free pellets, they compress the inner wall of the rectangular corrugated cylinder 12, causing a longitudinal change in the cylinder. This facilitates the vertical expansion and contraction of the cylinder, extending its service life. The coordinated use of the drive motor 17, main shaft 18, stirring rod 15, and filter plate 16 facilitates the filtration of the fuel pellets fed into the feed hopper 3, preventing large fuel particles from entering the furnace body 1 and causing incomplete combustion. During operation, the drive motor 17 is started, and then the drive motor 17 drives the stirring rod 15 to rotate via the main shaft 18. This causes the stirring rod 15 to mix the fuel pellets inside the feed hopper 3. Smaller fuel particles are then filtered out by the filter plate 16, while larger fuel particles remain in the feed hopper 3 and can be removed later. This method is simple to operate.
