Technical Field
[0001] This utility model relates to the field of steam engine technology, and in particular to a non-clogging biomass steam engine feed inlet structure. Background Technology
[0002] Biomass pellet fuel is a new type of clean fuel made from high-quality wood chips and straw as raw materials. It is produced by adding high-efficiency additives and undergoing processes such as crushing, mixing, extrusion, and drying to form pellets that can be directly burned. It is commonly used in steam stoves.
[0003] Since the fuel is made from wood chips and straw, flue gas carrying ash may be generated during combustion. This flue gas may rise with the hot air and adhere to the feed pipe or the inside of each stage of the fire channel, causing blockage in the furnace and affecting the combustion effect. In order to address this technical problem, this application proposes a blockage-proof biomass steam engine feed inlet structure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clog-resistant biomass steam engine feed inlet structure. The connecting inclined tube itself has an angle to prevent material from clogging inside. During combustion, a blower can be started to inject air into the connecting inclined tube through an air supply pipe to ensure that the fuel inside the combustion chamber can burn completely and reduce the generation of soot. At the same time, it can also prevent the flue gas generated during combustion from entering the screw conveyor along the connecting inclined tube and causing blockage that affects the feed.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A clog-resistant biomass steam generator feed inlet structure includes a combustion chamber. A connecting inclined pipe passes through the left end of the combustion chamber, and a feed assembly is installed at the left end of the connecting inclined pipe. An air supply pipe passes through the front end of the connecting inclined pipe, and a blower is fixedly connected to the other end of the air supply pipe. A box door is fixedly connected to the front end of the combustion chamber, and two box covers are hinged to the outer wall of the box door. A heating chamber is fixedly connected to the rear end of the combustion chamber. A steam pipe is connected to the inner wall of the heating chamber through a heating assembly. A water inlet is connected to the rear end of the heating chamber through a conveying assembly. A box body is fixedly connected to the top of the heating chamber, and an exhaust pipe passes through the top of the box body. An induced draft fan is installed at the right end of the exhaust pipe.
[0006] Furthermore, the feeding assembly includes a screw conveyor fixedly connected to the left end of the connecting inclined tube, a material box fixedly connected to the top of the screw conveyor, and a controller installed at the front end of the material box.
[0007] Furthermore, the right end of the blower is installed at the left end of the combustion chamber, a mesh is fixedly connected to the inner wall of the combustion chamber, and a fire port is provided at the top of the combustion chamber.
[0008] Furthermore, the heating assembly includes a first water chamber located on the inner wall of the heating chamber, a heating pipe passing through the top of the first water chamber, a steam box being fixedly connected to the top of the heating pipe, and the bottom of the steam pipe passing through the top of the steam box.
[0009] Furthermore, the bottom of the steam tank is fixedly connected to the left side of the top of the heating chamber, and a level gauge is fixedly connected to the left end of the steam tank.
[0010] Furthermore, the conveying assembly includes a water pipe extending through the rear end of the heating chamber, with the other end of the water pipe extending through the left end of the housing, and a second water chamber provided on the inner wall of the housing.
[0011] Furthermore, a water inlet is provided at the left end of the second water cavity, and the outer wall of the water inlet extends through the left end of the box.
[0012] This utility model has the following beneficial effects: In this invention, the inclined connecting tube itself has an angle that can prevent material from clogging inside. During combustion, a blower can be started to inject air into the inclined connecting tube through an air supply pipe to ensure that the fuel inside the combustion chamber can burn completely and reduce the generation of carbon black. At the same time, it can also prevent the flue gas generated by combustion from entering the screw conveyor along the inclined connecting tube and causing blockage that affects the feeding.
[0013] In this invention, the heat generated by combustion inside the combustion chamber can heat the water in the first water chamber and the heating tube. The high-temperature flue gas enters the heating chamber and the box body through the holes opened at the rear end of the combustion chamber and the rear end of the heating chamber, respectively, to heat the water in the second water chamber. The heat generated by combustion is fully utilized to raise the temperature of the water in the steam box and generate steam. Attached Figure Description

The connecting inclined pipe 12 itself has an angle to prevent material from clogging inside. During combustion, the blower 14 can also be started to inject air into the connecting inclined pipe 12 through the air supply pipe 13 to ensure that the fuel inside the combustion chamber 1 can be fully burned to reduce the generation of carbon black. At the same time, it can also prevent the flue gas generated by combustion from entering the screw conveyor 11 along the connecting inclined pipe 12 and causing blockage to affect the feeding. After the upper box cover 16 is opened, coal can be filled into it to assist the combustion of materials. The lower box cover 16 is opened to clean up the ash that has fallen into the bottom of the partition net 17.
[0018] Reference Figure 1 , Figure 3 and Figure 4A heating chamber 18 is fixedly connected to the rear end of the combustion chamber 1. A steam pipe 6 is connected to the inner wall of the heating chamber 18 through a heating assembly. The heating assembly includes a first water chamber 22 located on the inner wall of the heating chamber 18. A heating pipe 21 passes through the top of the first water chamber 22. A steam box 7 is fixedly connected to the top of the heating pipe 21. The bottom end of the steam pipe 6 passes through the top of the steam box 7. The bottom end of the steam box 7 is fixedly connected to the left side of the top of the heating chamber 18. A level gauge 8 is fixedly connected to the left end of the steam box 7. A box body 3 is fixedly connected to the top of the heating chamber 18. A water inlet 19 is connected to the rear end of the heating chamber 18 through a conveying assembly. The conveying assembly includes a water supply pipe 20 passing through the rear end of the heating chamber 18. The other end of the water supply pipe 20 passes through the left end of the box body 3. A second water chamber 23 is provided on the inner wall of the box body 3. The water inlet 19 passes through the left end of the second water chamber 23. The outer wall of the water inlet 19 passes through the left end of the box body 3. An exhaust pipe 5 passes through the top of the box body 3. An induced draft fan 4 is installed on the right end of the exhaust pipe 5. Specifically, water can be injected into the second water chamber 23 inside the housing 3 through the external pipe connected to the inlet 19. Then, under the action of the water supply pipe 20, water enters the first water chamber 22 and overflows into the steam box 7 along the heating pipe 21. At this time, the heat generated inside the combustion chamber 1 heats the water in the first water chamber 22 and the heating pipe 21. High-temperature flue gas enters the heating chamber 18 and the housing 3 through holes opened at the rear end of the combustion chamber 1 and the rear end of the heating chamber 18, respectively, to heat the water in the second water chamber 23. This fully utilizes the heat generated by combustion to raise the temperature of the water inside the steam box 7, causing it to evaporate and generate steam. A level gauge 8 installed on the outer wall of the steam box 7 is connected to the inside of the steam box 7, allowing observation of the remaining water level inside. The flue gas is guided by the induced draft fan 4 and discharged to the outside along the exhaust pipe 5. Working Principle: In practical use, the controller 10 can control the screw conveyor 11 to start conveying the material inside the hopper 9, sending it along the connecting inclined pipe 12 into the combustion chamber 1 for combustion. During combustion, the blower 14 can also be started to inject air into the connecting inclined pipe 12 through the air supply pipe 13 to ensure that the fuel inside the combustion chamber 1 can be fully burned to reduce the generation of soot. At the same time, it can also prevent the flue gas generated by combustion from entering the screw conveyor 11 along the connecting inclined pipe 12 and causing blockage that affects the feeding. The water required for steam generation is injected into the second water chamber 23 inside the housing 3 through the water inlet 19 external pipe, and then injected into the first water chamber 23 under the action of the water supply pipe 20. The water flows into the steam chamber 7 through the heating pipe 21. The heat generated by the combustion in the combustion chamber 1 heats the water in the first water chamber 22 and the heating pipe 21. The high-temperature flue gas enters the heating chamber 18 and the box 3 through the holes opened at the rear end of the combustion chamber 1 and the rear end of the heating chamber 18, respectively, to heat the water in the second water chamber 23. The heat generated by the combustion is fully utilized to make the water in the steam chamber 7 heat up and evaporate to produce steam. The flue gas is guided by the induced draft fan 4 and discharged to the outside through the exhaust pipe 5. The ash after combustion will fall into the bottom of the combustion chamber 1 through the holes on the partition 17. The side box cover 16 can be opened later to clean the ash.
