Description

Technical Field

[0001] This utility model belongs to the field of combustion engine technology, and specifically relates to a high-efficiency and energy-saving chain-driven automatic slag-cleaning biomass combustion engine. Background Technology

[0002] The function of a combustion furnace is to burn materials such as wood chips, waste straw, and biomass pellets to generate heat for other uses. The whole process is a process of energy conversion and transfer; the completeness of combustion is the key to the heat conversion efficiency.

[0003] The inventor's existing product is a biomass burner with publication number CN 216281342 U. It uses a circulating water layer to cool the furnace body, and a blower mechanism at the bottom of the furnace provides sufficient air for complete combustion of the pellets. However, during later applications, it was discovered that due to the closed structure of the furnace chamber, the pellets burn on the grate, causing slag to accumulate on the grate while fresh feed continuously enters the furnace. Simultaneously, the ventilation pipe IV blows air onto the grate, causing the two materials to mix. This airflow further mixes the slag and fresh feed, resulting in slag filling the entire furnace chamber, which is detrimental to the complete combustion of the fresh feed. Therefore, based on the shortcomings of the previous product, the inventor has provided a new solution to improve it. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency and energy-saving chain automatic slag-cleaning biomass burner. It can transfer and clean the slag in real time during the combustion process through the chain grate mechanism, ensuring the combustion environment of the new material. At the same time, the setting of baffles and ventilation openings can improve the combustion efficiency and achieve the effect of high efficiency and energy saving.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency and energy-saving automatic chain grate biomass burner includes a furnace body, a furnace chamber, a feeding mechanism, a slag cleaning mechanism, and a chain grate mechanism.

The feeding mechanism is located above the furnace body and connected to the furnace chamber, the slag cleaning mechanism is located below the furnace chamber, and the chain grate mechanism is located inside the furnace chamber and above the slag cleaning mechanism. One end of the furnace body has a furnace opening connected to the furnace chamber for ignition. A protective cover is fitted onto the furnace opening and is fixedly connected to the side wall of the furnace body, with a gap between the cover and the furnace opening. The feeding mechanism feeds the biomass into the chain grate mechanism inside the furnace chamber, and then the furnace opening is ignited for combustion. The chain grate mechanism carries the burned slag to the slag cleaning mechanism for cleaning.

[0007] The bottom of the furnace chamber is provided with a second baffle connected to the inner wall of the furnace chamber to block the wind; a first baffle is provided on the outer wall of one end of the furnace chamber, which can cause the gas in the interlayer to surge upward when it flows through the first baffle, thereby increasing the wind speed and diverting the gas.

A sprocket is located at the end of the third motor shaft and connected to the sprocket on the reducer's power shaft via a chain. The reducer's output shaft connects to the power roller to control its speed. The third motor provides power for the rotation of the power roller, thereby driving the chain grate. The chain grate is inclined, with the end closer to the furnace opening lower than the end closer to the slag removal mechanism. The inclination direction of the chain grate is opposite to that of the furnace top, concentrating the fire at the feed inlet. An oxygen supply box is located inside the chain grate, with air inlets on it. The two sides of the oxygen supply box are connected to a first passage. The upper surface of the chain grate is aligned with a second passage to facilitate air intake and ensure sufficient air for complete combustion. The transmission principle and structure of the chain grate mechanism described above are existing technologies and will not be elaborated upon here.

[0009] The furnace body has a cleaning port and a repair port on both sides, and the cleaning port and repair port are equipped with openable and closable sealing doors. A bracket is provided at one end of the furnace body for installing the slag cleaning mechanism. A gas box connected to the internal interlayer is provided at one end of the furnace body. A gas pipe is provided on the gas box, which is connected to the feeding mechanism. A gas passage is provided on one side of the gas box, which is connected to the furnace body. A fan is provided on one side of the gas box to provide air power to the gas box. The cleaning port is located below the second partition of the furnace to facilitate manual removal of residual slag falling from the chain grate. The repair port is aligned with the oxygen supply air box and the first opening to facilitate observation and cleaning of slag.

[0010] The slag removal mechanism includes a second cylinder, a second motor, and a second auger. The second cylinder is fixed to one end of the bottom of the furnace body, and the second auger is located inside the second cylinder. The second cylinder has a material receiving port and a guide plate for receiving materials. The two ends of the second auger shaft are rotatably connected to the side wall of the furnace body. A sprocket is provided at one end of the second auger shaft, and a bracket is rotatably connected at the other end of the second auger shaft for discharging materials. The second motor is fixed to the side wall of the furnace body, and a sprocket is provided at the end of the second motor shaft, which is connected to the sprocket at the end of the second auger shaft by a chain. The second motor drives the second auger to rotate and transport the burned slag outward.

[0011] The feeding mechanism includes a first cylinder, a first spiral auger, a first motor, and a feeding end. The feeding end is connected to one end of the first cylinder and the feed inlet on the top of the furnace. The first cylinder is obliquely mounted on the top of the furnace via a fixing frame. A filling port is provided at one end of the first cylinder. The first spiral auger is located inside the first cylinder.

The fixed shafts are rotatably connected to the sidewalls of the air duct, and the sidewalls of the air duct have positioning holes. An adjusting arm is fixedly connected to one of the fixed shafts. The adjusting arm has an adjusting groove, and a locking block is located in the adjusting groove and can slide within the groove. The locking block has a threaded bolt. By rotating the adjusting arm, the baffle is controlled to rotate around the fixed shaft, thereby controlling the air intake of the air duct. Then, by rotating the bolt, one end of the bolt is inserted into the positioning hole to achieve fixation, thus completing the adjustment process. During this process, the locking block can slide within the adjusting groove to adapt to the application of different positioning holes.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1) The first spiral auger in the feeding mechanism can directly transport fuel into the furnace and drop it onto the chain grate mechanism. The gas pipe connected to the first cylinder can provide strong cold air, which not only accelerates the fuel into the furnace, but also forms positive air pressure to suppress the fire and prevent the fire in the furnace from igniting the fuel in the first cylinder in the feeding mechanism, and from causing backfire in the furnace to burn the first spiral auger. At the same time, it cools down the first spiral auger. Furthermore, a large amount of air can enter through the first and second openings to provide sufficient air for fuel combustion, and the fuel can be dispersed and fully burned through the transmission of the chain grate.

[0016] 2) The use of the chain grate mechanism can not only disperse the fuel in conjunction with the air entering the furnace, but also concentrate the slag after combustion into the slag cleaning mechanism for cleaning. It can maintain continuous cleaning of the chain grate, facilitate the combustion of new material, and further improve the combustion efficiency of fuel.

[0017] 3) There is a jacket between the furnace body and the furnace chamber. Air can flow quickly in the jacket and then be discharged through the gap between the protective cover and the furnace opening, which provides a cooling effect. The use of the first baffle can divert the air. While the air flows along the jacket to cool down, it allows enough air to enter the furnace chamber to ensure sufficient combustion air.

[0018] 4) The airway is equipped with a baffle, and there are fixed shafts on both sides of the baffle. Adjusting arms are fixedly connected to the fixed shafts. By rotating the adjusting arms, the baffle is controlled to rotate around the fixed shaft, thereby controlling the air intake of the airway and air tube. Attached Figure Description
