Description

Technical Field

[0001] The utility model relates to the field of biomass boiler return conveyors, in particular to a split sleeve device for the ash discharge pipe of a biomass boiler return conveyor. Background Art

[0002] A biomass boiler return conveyor is a device that directly returns the solid materials separated by a separator to the furnace or an external heat exchanger. During the operation of the boiler, the ash particles carried by the flue gas and the burning coal particles enter the separator through the furnace. Most of the solid particles are separated in the separator and then return to the furnace through the return conveyor. This cyclic process has a direct impact on the combustion efficiency, superheated steam temperature, and load capacity of the boiler. The ash discharge pipe of a biomass boiler return conveyor is a pipe used to discharge waste or ash slag. The ash discharge pipe is installed at the lower part or the lower side of the return conveyor for discharging ash slag.

[0003] However, most of the existing biomass boiler return conveyors and ash discharge pipes on the market are integrated, resulting in the inability to split the ash discharge pipe, which greatly reduces the practicability of the device. Summary of the Utility Model

[0023] Example 1

[0024] Reference Figures 1-4 , which is the first embodiment of the present utility model, provides a split sleeve device for the ash discharge pipe of a biomass boiler return feeder, including an installation base 1 and an ash pipe 5. One side of the installation base 1 is fixedly connected to a return feeder body 2. The return feeder body 2 is an existing device and will not be elaborated here. A groove 10 is formed on the front surface of the ash pipe 5. A cylinder 11 is fixedly connected to the inner bottom wall of the groove 10. The top of the cylinder 11 is fixedly connected to a lifting plate 12. The bottom of the lifting plate 12 is fixedly connected to a telescopic rod 13. The bottom of the telescopic rod 13 is fixedly connected to the inner bottom wall of the groove 10. A spring 14 is fixedly connected to the inner wall of the groove 10. The spring 14 is in a compressed state. One end of the spring 14 is fixedly connected to an inclined plate 15. One side of the inclined plate 15 is fixedly connected to a mounting block 16. A through groove 18 is formed on the inner side wall of the groove 10.

[0025] The ash pipe 5 is slidably sleeved with the return feeder body 2. The lifting plate 12 is in the shape of a "ring" structure. The shape of the groove 10 is the same as that of the lifting plate 12. The lifting plate 12 is slidably connected to the groove 10. The mounting block 16 is slidably sleeved with the through groove 18. The operation of the cylinder 11 can drive the lifting plate 12 to move upward, and then the inclined plate 15 will be squeezed, causing the inclined plate 15 to drive the mounting block 16 to move into the internal of the clamping groove 17.

[0026] A clamping groove 17 is formed on the inner wall of the ash pipe 5, and the mounting block 16 is movably clamped with the clamping groove 17. The mounting block 16 can play a role in limiting the ash pipe 5, so that the ash pipe 5 is clamped and installed inside the return feeder body 2, and the ash pipe 5 can achieve the function of discharging ash.

[0027] During the use process, first, when the ash pipe 5 needs to be disassembled, the cylinder 11 is started. The cylinder 11 will drive the lifting plate 12 to move downward. Since the spring 14 is in a compressed state, when the lifting plate 12 is separated from the inclined plate 15, the reset of the spring 14 will drive the mounting block 16 to move into the internal of the groove 10, and then the mounting block 16 is separated from the clamping groove 17;

[0028] Secondly, after the mounting block 16 is no longer in contact with the clamping groove 17, the ash pipe 5 can be disassembled. The cylinder 11 on the new ash pipe 5 is started. The cylinder 11 drives the lifting plate 12 to move upward, and then the lifting plate 12 squeezes the inclined plate 15, and the inclined plate 15 will drive the mounting block 16 to move into the internal of the clamping groove 17;

[0029] Finally, the mounting block 16 can play a role in limiting the ash pipe 5, so that the ash pipe 5 is clamped and installed inside the return feeder body 2, and the ash pipe 5 can achieve the function of discharging ash.

[0030] Example 2

[0031] ReferenceFigures 1-4 This is the second embodiment of the present utility model. A material guiding block 3 is fixedly connected to the inner wall of the return feeder body 2. A channel 4 is opened at the top of the material guiding block 3. The inner wall of the channel 4 is an inclined surface. Ash and slag can enter the ash pipe 5 through the channel 4, and the channel 4 can play a role in guiding the material.

[0032] An electric telescopic rod 6 is fixedly connected to the outer wall of the ash pipe 5. A lifting rod 7 is fixedly connected to the bottom of the electric telescopic rod 6. The lifting rod 7 is of a "U" - shaped structure. A lifting ring 8 is fixedly connected to the top of the lifting rod 7. The electric telescopic rod 6 can drive the lifting ring 8 to move through the lifting rod 7. The lifting ring 8 is of a circular ring structure and will not affect the discharge of ash and slag.

[0033] The outer wall of the lifting ring 8 is slidably connected to the inner wall of the ash pipe 5, and a stirring frame 9 is fixedly connected to the top of the lifting ring 8. When the lifting ring 8 moves, it can drive the stirring frame 9 to lift, and then the stirring frame 9 can drive the ash and slag to rotate, so as to dredge the blocked ash and slag.

[0034] During the use process, the electric telescopic rod 6 can drive the lifting ring 8 to move through the lifting rod 7. The lifting ring 8 is of a circular ring structure. When the lifting ring 8 moves, it can drive the stirring frame 9 to lift, and then the stirring frame 9 can drive the ash and slag to rotate, so as to dredge the blocked ash and slag.
