Description

Technical Field

[0001] The utility model belongs to the technical field related to biomass boilers, and particularly relates to a fuel delivery device for a biomass boiler. Background Art

[0002] The boiler adopts the reciprocating grate, the combustion equipment most suitable for biomass fuel combustion. The boiler has a larger furnace space than traditional boilers in terms of structural design. At the same time, a very reasonable secondary air arrangement is conducive to the full combustion of a large amount of volatiles that are instantly released during the combustion of biomass fuel. The boiler can be equipped with a fuel (gas) ignition burner to realize automatic ignition. The feeding, combustion, slag removal, water supply, and ignition of the boiler can all be automatically controlled, which is very convenient to operate. The boiler is equipped with an automatic ash cleaning device, which can timely remove the ash accumulation on the heating surface of the boiler to ensure efficient and stable operation of the boiler. An economizer is arranged at the tail of the boiler, and an air preheater can also be arranged according to user needs. Compared with traditional boilers, the boiler has higher efficiency and lower exhaust gas temperature. During its combustion process, in order to ensure the combustion cycle, a fuel delivery device is required to deliver fuel. During the delivery of fuel, the boiler can be continuously burned, but it still has the following disadvantages in actual use:

[0003] When the fuel delivery device of the biomass boiler is working, the fuel is directly delivered to the boiler for combustion. During the delivery process, the fuel is directly transported to the boiler through the pipeline, which is easy to accumulate in the boiler. When the fuel accumulates and burns, the combustion is easy to be incomplete, resulting in insufficient cleanliness of the combustion during operation;

[0004] When the biomass boiler fuel delivery device is working, it delivers the fuel. During the operation and material transportation process, it is easy to cause congestion in the pipeline, resulting in insufficient smoothness of fuel transportation and inconvenience in use. Utility Model Content

[0005] The utility model aims to provide a biomass boiler fuel delivery device, which solves the problems that the biomass boiler fuel delivery device is prone to fuel accumulation and incomplete combustion when delivering fuel, and the fuel delivery is prone to congestion in the pipeline, resulting in insufficient smoothness of fuel delivery, by arranging a delivery cylinder, a feed cylinder and an output shell.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a fuel delivery device for a biomass boiler, comprising a delivery cylinder, a feed cylinder and an output shell, wherein one end of the delivery cylinder is closed and the other end is open, an output shell is arranged below the end of the delivery cylinder which is open, conveying blades are fixed in an annular array on the inner wall of the output shell, a feed cylinder is arranged above the end of the output shell which is away from the output shell on the peripheral side, a vibration motor is arranged above the top end of the feed cylinder, and when working, the biomass particle fuel transported in the feed cylinder is transported to the output shell through the delivery cylinder, and the biomass particle fuel is evenly transported through the conveying blades through the output shell.

[0008] Furthermore, a driving motor is fixed on one end face of the closed feeding barrel, a driving shaft is fixed on the output end of the driving motor, the driving shaft is movably connected through the feeding barrel, and the feeding barrel is driven by the driving motor to rotate the driving shaft.

[0009] Furthermore, a spiral blade is fixed on the circumference of the driving shaft in the feeding tube, and a fixing hole is opened at one end of the upper circumference of the feeding tube close to the driving motor. When the driving shaft rotates, the biomass particle fuel is transported through the spiral blade and the bottom end of the feeding tube is fixed through the fixing hole.

[0010] Furthermore, a connecting plate is fixed to the top of the feeding barrel, the vibration motor is fixed in the middle of the top of the connecting plate, a vibration shaft is fixed to the output end of the vibration motor, the vibration shaft is movably connected in the connecting plate, and a vibration plate is fixed to the bottom end of the vibration shaft. When the feeding barrel is working, it is connected to the vibration motor through the connecting plate, and the vibration shaft is driven to vibrate through the vibration motor. When the vibration shaft vibrates, the vibration plate is driven to vibrate.

[0011] Furthermore, the bottom end of the feed barrel is fixedly connected to a focusing barrel, the bottom end of the focusing barrel is fixedly connected to a delivery pipe, the vibration plate is arranged in the delivery pipe, and the bottom end of the delivery pipe is fixed in a fixed hole, so that the material in the feed barrel is transported to the delivery pipe through the focusing barrel and then transported to the delivery barrel.

[0012] Furthermore, a connecting pipe is fixedly connected to the top of the output shell, and the top of the connecting pipe is fixedly connected to one end of the feed barrel which is open. A fixing rod is commonly fixed to one side of the conveying blades close to the inner axis of the output shell. When the output shell is working, the biomass particle fuel is transported to the output shell through the connecting pipe.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the fuel delivery device of the biomass boiler is prone to fuel accumulation and incomplete combustion when delivering fuel by arranging a delivery cylinder and a feed cylinder. After the biomass particle fuel is delivered to the connecting pipe, the biomass particle fuel is guided to the output shell through the connecting pipe. During the delivery in the output shell, the biomass particle fuel is evenly delivered by the delivery blades, so that the biomass particle fuel is evenly delivered to the combustion position, so that when working, the uniformity of fuel delivery is guaranteed, the uneven delivery of the biomass particle fuel is prevented, and the uniformity and sufficiency of the combustion of the biomass particle fuel are increased.

[0015] The utility model solves the problem that the biomass boiler fuel delivery device is prone to congestion in the pipeline during fuel delivery, which causes the fuel delivery to be not smooth enough by arranging a delivery cylinder and an output shell. The utility model guides the biomass particle fuel into the feed cylinder, and after entering the feed cylinder, the biomass particle fuel is concentratedly delivered to the concentration cylinder, and then delivered to the delivery pipe after being concentrated by the concentration cylinder. When the vibration plate vibrates, the biomass particle fuel is smoothly delivered to the delivery cylinder through the delivery pipe, so that the biomass boiler delivery device can deliver the fuel more smoothly and the delivered fuel flow rate is more uniform.
