[0002] The ash hopper is an important part of the boiler system and is usually located below the dust collector for collecting the dust captured by the dust collector. During the operation of the boiler, when the flue gas passes through the dust collector, the dust particles therein will be captured by the filter material inside the dust collector and deposited in the ash hopper. The function of the ash hopper is to temporarily store the captured dust.

[0032] In the embodiment of the present application, by providing a boiler ash conveying device, the following problems are solved: during the operation of the boiler, after the fine soot at the tail is collected by the dust collector, it deposits in the ash hopper of the dust collector. The accumulation of dust will increase the operating resistance of the dust collector, affect the normal operation of the fan and the ventilation efficiency of the boiler. If the dust in the ash hopper is not cleaned in time, a large amount of dust may enter the atmosphere through the discharge port of the dust collector, causing environmental pollution. During the process of cleaning the dust in the ash hopper, the difficulty of cleaning and maintenance is high, the dust is easily dispersed into the air, and the harmful substances in the dust may also cause long-term harm to the surrounding environment and human health.

[0033] To better understand the above technical solution, the following will describe the above technical solution in detail in conjunction with the specification drawings and specific implementation manners.

[0034] An embodiment of the present utility model discloses a boiler ash conveying device. As shown in the attached Figures 1-4 figure, it includes a bin pump 1. A dust collector ash hopper main body 2 is connected to the bin pump 1. The dust collector ash hopper main body 2 is composed of a multi-tube dust collector ash hopper 201 and a bag dust collector ash hopper 202.

[0035] An inlet valve 101 is provided on the pipeline between the bin pump 1 and the dust collector ash hopper main body 2. An air supplement valve 103 is provided at the bottom of the bin pump 1. The air supplement valve 103 is connected to a conveying pipe 3. A balance valve 1011 is connected to the bin pump 1. The balance valve 1011 is connected to the dust collector ash hopper main body 2 through a pipeline.

[0036] The number of bin pumps 1 is multiple groups, and the multiple groups of bin pumps 1 are connected by pipelines. The pipelines connecting the multiple groups of bin pumps 1 are connected to the conveying pipe 3, so as to use the conveying pipe 3 to convey the soot on the multiple groups of bin pumps 1 and the dust collector ash hopper main body 2.

[0037] Support legs 104 are provided at the bottom of the bin pump 1. The support legs 104 are fixed to the ground by bolts. The support legs 104 provide stable support for the bin pump 1, thereby ensuring that the pipeline connecting the bin pump 1 is under stable force and not easily shaken, so that the connection between the pipeline connecting the bin pump 1 and the bin pump 1 is stable and not prone to leakage.

[0038] Multiple groups of bin pumps 1 are connected by a conveying pipe 3. The conveying pipe 3 is composed of an inner lining of ceramic wear-resistant material. An air source 7 is connected to the conveying pipe 3. The air source 7 is used to supply air to the inside of the conveying pipe 3, so as to facilitate ash conveying;

[0039] One end of the conveying pipe 3 far from the air source 7 is connected to an ash silo 4. An ash discharge valve 301 is provided on the conveying pipe 3;

[0040] A middle material level meter 5 and a high material level meter 6 are provided on the silo pump 1 , a hopper material level meter 200 is provided inside the dust collector hopper body 2 , and an air intake valve 102 is provided on the side of the silo pump 1 , and the air intake valve 102 is connected to the conveying pipe 3 .

[0041] In the boiler ash conveying device, the dust collector collects fine smoke ash and temporarily stores it in the dust collector ash hopper body 2. When the ash hopper level meter 200 detects that the ash amount reaches the conveying condition, the feed valve 101 is opened, and the smoke ash enters the silo pump 1 under the action of gravity. At the same time, the balance valve 1011 is opened, and the air in the silo pump 1 returns to the dust collector ash hopper body 2. When the middle level meter 5 in the silo pump 1 detects that the smoke ash is at the middle level, the feed valve 101 and the balance valve 1011 are closed, and the air intake valve 102 and the air supply valve 103 are opened. When the pressure of the air intake pipe connected to the silo pump 1 reaches the set value, the ash outlet valve 301 is opened, and the smoke ash is subjected to the action of compressed air and begins to be conveyed to the ash storage 4 through the conveying pipe 3.

[0042] A discharging mechanism is provided at the bottom of the ash bin 4, and the discharging mechanism includes:

[0043] The docking seat 401 is arranged at the bottom of the ash bin 4;

[0047] The device adopts a discharge mechanism design, and uses a discharge nozzle 403 and an extension tube 404 to conveniently discharge the ash inside the ash bin 4 to the tank truck for transportation. The extension tube 404 is clamped on the discharge nozzle 403 by a clamping bolt 405, so that the position of the extension tube 404 is easy to adjust, so that it is suitable for receiving materials from tank trucks of different heights, ensuring that the tank trucks receive materials stably.

[0048] A clamping block 406 is fixedly connected to the docking platform 402, and the clamping block 406 is movably clamped in the docking seat 401. A locking sleeve 407 is provided on the docking seat 401, and a slider 4071 is slidably connected in the locking sleeve 407. The bottom and top of the slider 4071 are respectively fixedly connected with a locking rod 4072 and a spring 4073. The locking rod 4072 is movably inserted in the clamping block 406, and a pull rod 4074 is provided on the top of the slider 4071.

[0049] The device is designed with a clamping block 406 and a locking sleeve 407, so that the docking seat 401 and the docking platform 402 can be easily disassembled and assembled. Therefore, when the feed nozzle 403 and the extension tube 404 are blocked, they can be quickly disassembled, unblocked and maintained, thereby ensuring that the device is easy to maintain.

[0050] When installing the docking base 401 and the docking platform 402, first pull the pull rod 4074 upward, so that the pull rod 4074 drives the slider 4071 and the locking rod 4072 to move and compress the spring 4073. At this time, dock the docking base 401 and the docking platform 402, so that the latch 406 is snapped into the docking base 401. After complete snapping, release the pull rod 4074, and the spring 4073 resets and pushes the slider 4071 and the locking rod 4072 to move, so that the locking rod 4072 is inserted into the latch 406 to realize the installation and locking of the docking base 401 and the docking platform 402;

[0051] Notches corresponding to the material discharge nozzle 403 and the extension pipe 404 are provided on the docking base 401, the docking platform 402 and the latch 406.
