Description

Technical Field

[0001] This utility model relates to the field of gasification boiler technology, specifically a longitudinally mounted semi-gasification biomass gasification boiler. Background Technology

[0002] With the increasing global demand for renewable energy and increasingly stringent environmental regulations, the market demand for semi-gasification biomass gasification boilers has increased significantly. By converting biomass materials into combustible gas, semi-gasification biomass gasification boilers not only effectively reduce dependence on traditional fossil energy sources such as coal, but also significantly reduce carbon emissions and air pollution.

[0003] Existing technology, such as the patent publication number "CN215675830U", discloses a biomass semi-gasification boiler for linen washing. This patent relates to the field of hotel equipment technology and includes a furnace. A support base is fixedly connected to the bottom of the furnace, and hydraulic arms are fixedly connected to both the front and back of the furnace. The free ends of the two hydraulic arms are fixedly connected through a closed door. In use, the smoke generated during combustion in the furnace is transported through a flue pipe to a dust collector for filtration before being discharged. As the smoke moves inside the flue pipe, it contacts the inclined surface of the guide block, causing the guide block to be stressed. This causes the main and secondary transfer rings to rotate via the main and secondary steering grooves. The rotation of the main and secondary transfer rings drives the scraper to rotate in the same direction, scraping and cleaning the inner wall of the flue pipe, removing attached particles that are discharged with the smoke. Furthermore, the centrifugal force during rotation makes it difficult for particles to adhere to the surface.

[0004] However, the current biomass semi-gasification boilers for linen washing have the following problems: when biomass fuel is poured into the boiler, the fuel will accumulate between the feed inlet and the furnace body, which will lead to local overheating and ash accumulation and coking during subsequent fuel combustion. In view of this, we propose a longitudinal semi-gasification biomass gasification boiler. Utility Model Content

[0005] The purpose of this utility model is to provide a longitudinally mounted semi-gasification biomass gasification boiler, which solves the above-mentioned problems.

[0008] Preferably, the end of the slide bar near the inner wall of the boiler furnace is set with an inclined surface, the push plate is in contact with the top surface of the lower plate, the abutting block is set with a right angle triangle, and there are several abutting blocks, and the several abutting blocks are located on the movement trajectory of the inclined surface of the slide bar.

[0009] Preferably, the homogenizing device further includes a fixed block, a rotating plate, a connecting plate, and a homogenizing plate. The fixed block is fixedly installed on the top outer wall of the push plate, the rotating plate is rotatably installed on the inner wall of the fixed block, the connecting plate is fixedly installed on the bottom of the rotating plate, and the homogenizing plate is fixedly installed on the side wall of the connecting plate.

[0010] Preferably, there are several fixing blocks, and a short plate is provided on the top of the rotating plate, and the short plate of the rotating plate is located on the movement trajectory of the outer shell.

[0011] Preferably, the unblocking device includes a pentagonal rod, a sliding rod, and an abutment ball.

[0014] By employing the above technical solution, this utility model provides a longitudinally mounted semi-gasification biomass gasification boiler. It possesses at least the following beneficial effects:

[0015] (1) By setting up a homogenizing device, the sliding rod drives the connecting block to move inward, the connecting block drives the push plate to move inward, and the sliding rod is reset by the elastic force of the spring. While the push plate rotates, it can also move back and forth, thus realizing the back and forth movement of the push plate to push the biomass fuel into the boiler body. This not only effectively prevents the biomass fuel from accumulating too much between the feed pipe and the boiler body, but also improves the combustion efficiency and thermal energy utilization rate. The homogenizing plate rotates upward, and the rotation of the homogenizing plate throws the biomass fuel at the front end upward. With the setting of the push plate, the uniform distribution of biomass fuel in the boiler body is further improved, which further promotes the complete combustion of fuel, improves the thermal efficiency of the boiler, and also reduces the possibility of local high temperature and ash accumulation and coking, thereby reducing the exhaust loss and reducing the pollution to the environment.

[0016] (2) By setting up a dredging device, when the pusher frame rotates, the pusher frame will abut against the abutting ball. The abutting ball drives the sliding rod to slide downward on the inner wall of the pentagonal rod. The abutting ball is elastic under the spring two. After the abutting ball releases the abutting frame, it resets upward. The bottom plate can limit the length of the sliding rod to reset upward. The up and down movement of the abutting ball can dredge the ash and slag attached to the slots of the lower plate, prevent the lower plate from being blocked, improve the operating efficiency and stability of the boiler, and also reduce the burden of maintenance work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A vertically arranged semi-gasification biomass gasification boiler, such as Figures 1-4As shown, the boiler includes a boiler body 1. A feed pipe 11 is fixedly installed on the outer wall of the middle section of the boiler body 1. An exhaust pipe 12 is fixedly installed on the outer wall of the top section of the boiler body 1. A collection box 13 is slidably installed on the inner wall of the bottom section of the boiler body 1. A gasification chamber 14 is fixedly installed on the inner wall of the top section of the boiler body 1. A blower 15 is fixedly installed on the outer wall of the bottom section of the boiler body 1. A burner 16 is fixedly installed on the top section of the boiler body 1. A lower plate 17 is fixedly installed on the inner wall of the boiler body 1, and slots are formed on the surface of the lower plate 17. A homogenizing device 2 is provided on the top of the lower plate 17, and a clearing device 3 is provided on the bottom of the lower plate 17. The homogenizing device 2 includes a motor 21, a rotating rod 22, a spiral conveyor blade 23, a fixed column 24, a rotating shaft 1 25, a rotating shaft 26, and a transmission bar 2. 7. The components include: outer casing 28, pusher frame 29, slide rod 210, connecting block 211, push plate 212, spring 213, and contact block 214. Motor 21 is fixedly installed at the bottom of feed pipe 11. Biomass fuel is poured into the boiler body 1 through feed pipe 11. Motor 21 is turned on. Rotating rod 22 is fixedly installed at the output end of motor 21. Motor 21 drives rotating rod 22 to rotate. Spiral conveying blades 23 are fixedly installed on the outer wall of rotating rod 22. Rotating rod 22 drives spiral conveying blades 23 to rotate. Fixed column 24 is fixedly installed on the top of the center end of lower plate 17. Rotating shaft 25 is rotatably installed on the outer wall of fixed column 24. Rotating shaft 26 is fixedly installed on the outer wall of the bottom end of rotating rod 22. Transmission strips 27 are rotatably installed on the outer walls of rotating shaft 25 and rotating shaft 26 respectively. The spiral conveyor blades 23 transport biomass fuel into the boiler body 1. The burner 16 is then turned on, burning the biomass fuel. The blower 15 circulates air inside the boiler. The combustible gas produced by the biomass fuel enters the gasification chamber 14 through gasification, and is then discharged through the exhaust pipe 12. Unburned biomass fuel provides heat to the boiler body 1. However, after the biomass fuel is transported into the boiler body 1 by the spiral conveyor blades 23, a large amount of biomass fuel accumulates between the feed pipe 11 and the boiler body 1, resulting in higher heat generation during combustion. This is not conducive to heat absorption and utilization. At this time, the rotating rod 22 drives the rotating shaft 26 to rotate, which in turn drives the transmission bar 27 to rotate. The transmission bar 27 then drives the fixed column 24... The rotating shaft 25 rotates, the outer casing 28 is fixedly installed on the inner wall between the feed pipe 11 and the boiler body 1, the pusher frame 29 is fixedly installed on the outer wall of the rotating shaft 25 located at the bottom of the transmission bar 27, the rotating shaft 25 drives the pusher frame 29 to rotate, the slide rod 210 is slidably installed on the inner wall of the pusher frame 29, the pusher frame 29 drives the slide rod 210 to rotate, the end of the slide rod 210 near the inner wall of the boiler body 1 is set with an inclined surface, the connecting block 211 is fixedly installed on the outer wall of the slide rod 210, the slide rod 211 drives the connecting block 211 to rotate, the push plate 212 is fixedly installed on the end of the connecting block 211 away from the slide rod 210, the connecting block 211 drives the push plate 212 to rotate, the push plate 212 contacts the top surface of the lower plate 17, and the spring 213 is set between the slide rod 210 and the pusher frame 29.The contact block 214 is fixedly installed on the inner wall of the boiler body 1. The contact block 214 is a right-angled triangle, and there are several contact blocks 214 located on the movement trajectory of the inclined surface of the slide rod 210. Simultaneously, the inclined surface of the slide rod 210 abuts against the inclined surface of the contact block 214, causing the slide rod 210 to drive the connecting block 211 to move inward. The connecting block 211 then drives the push plate 212 to move inward. The slide rod 210 is then reset by the elastic force of the spring 213. While rotating, the push plate 212 can also move back and forth, thus pushing biomass fuel into the boiler body 1. This not only effectively prevents excessive accumulation of biomass fuel between the feed pipe 11 and the boiler body 1, but also improves combustion efficiency and thermal energy utilization.

[0027] The homogenizing device 2 also includes a fixed block 215, a rotating plate 216, a connecting plate 217, and a homogenizing plate 218. The fixed blocks 215 are fixedly installed on the top outer wall of the push plate 212, and there are several fixed blocks 215. The rotating plate 216 is rotatably installed on the inner wall of the fixed blocks 215. When the push plate 212 pushes the biomass fuel into the boiler body 1, the push plate 212 drives the fixed blocks 215 to rotate. The top of the rotating plate 216 is provided with a short plate, and the short plate of the rotating plate 216 is located on the movement trajectory of the outer shell 28. The fixed blocks 215 drive the rotating plate 216 to rotate, and the short plate at the top of the rotating plate 216 abuts against the bottom end of the outer shell 28, causing the rotating plate 216 to rotate counterclockwise downwards. The connecting plate 217 is fixedly installed at the bottom of the rotating plate 216. The rotating plate 216 drives the connecting plate 217 to rotate counterclockwise. The homogenizing plate 218 is fixedly installed on the side wall of the connecting plate 217. The connecting plate 217 drives the homogenizing plate 218 to rotate counterclockwise, that is, the homogenizing plate 218 rotates upward. The rotation of the homogenizing plate 218 throws the biomass fuel at the front end upward. With the setting of the push plate 212, the uniform distribution of biomass fuel in the boiler body 1 is further improved, which further promotes the complete combustion of fuel, improves the thermal efficiency of the boiler, and also reduces the possibility of local high temperature and ash accumulation and coking, thereby reducing flue gas loss and mitigating environmental pollution.

[0028] In operation, the longitudinally mounted semi-gasification biomass gasification boiler of this utility model involves pouring biomass fuel into the boiler body 1 through the feed pipe 11, turning on the motor 21, which drives the rotating rod 22 to rotate, which in turn drives the spiral conveying blades 23 to rotate. The spiral conveying blades 23 transport the biomass fuel into the boiler body 1. The burner 16 is then turned on to burn the biomass fuel. The blower 15 is turned on to circulate air inside the boiler. The combustible gas produced by the biomass fuel enters the gasification chamber 14 through gasification, and is then discharged through the exhaust pipe 12. Unburned biomass fuel provides heat energy to the boiler body 1. However, after the biomass fuel is transported into the boiler body 1 by the spiral conveying blades 23, a large amount of biomass fuel accumulates between the feed pipe 11 and the boiler body 1, resulting in higher heat generation during combustion. This is not conducive to the absorption and utilization of heat energy. Rotating rod 22 drives rotating shaft 26 to rotate, rotating shaft 26 drives transmission bar 27 to rotate, transmission bar 27 drives rotating shaft 25 on fixed column 24 to rotate, rotating shaft 25 drives pushing frame 29 to rotate, pushing frame 29 drives sliding rod 210 to rotate, sliding rod 210 drives connecting block 211 to rotate, connecting block 211 drives push plate 212 to rotate. At the same time, the inclined surface of sliding rod 210 abuts against the inclined surface of contact block 214, causing sliding rod 210 to drive connecting block 211 to move inward, connecting block 211 to drive push plate 212 to move inward, and sliding rod 210 is then reset by the elastic force of spring 213. While pushing plate 212 rotates, it can also move back and forth left and right, realizing the left and right back and forth movement of push plate 212 to push biomass fuel into the boiler body 1. This can not only effectively prevent the problem of excessive accumulation of biomass fuel between feed pipe 11 and boiler body 1, but also improve combustion efficiency and thermal energy utilization.

[0029] When the pusher plate 212 pushes the biomass fuel into the boiler body 1, the pusher plate 212 drives the fixed block 215 to rotate, and the fixed block 215 drives the rotating plate 216 to rotate. The short plate at the top of the rotating plate 216 abuts against the bottom of the outer shell 28, causing the rotating plate 216 to rotate counterclockwise downwards. The rotating plate 216 drives the connecting plate 217 to rotate counterclockwise, and the connecting plate 217 drives the homogenizing plate 218 to rotate counterclockwise, that is, the homogenizing plate 218 rotates upwards. The rotation of the homogenizing plate 218 throws the biomass fuel at the front end upwards. With the setting of the pusher plate 212, the uniform distribution of biomass fuel in the boiler body 1 is further improved, which further promotes the complete combustion of fuel, improves the thermal efficiency of the boiler, and also reduces the possibility of local high temperature and ash accumulation and coking, thereby reducing flue gas loss and mitigating environmental pollution.

[0030] Example 2

[0031] like Figure 5As shown, the unblocking device 3 includes a pentagonal rod 31, a sliding rod 32, and an abutting ball 33. The pentagonal rod 31 is fixedly installed at the bottom of the center end of the lower plate 17. The sliding rod 32 passes through and slides on the top of the pentagonal rod 31. The sliding rods 32 are grouped in sets of three, and each group of sliding rods 32 passes through and slides on the top of the pentagonal rod 31. The abutting ball 33 is fixedly installed on the top of the sliding rod 32. The abutting ball 33 is located on the movement trajectory of the pusher frame 29, and the abutting ball 33 slides on the inner wall of the slot of the lower plate 17.

[0032] The unblocking device 3 also includes a second spring 34 and a base plate 35. The second spring 34 is located between the pentagonal rod 31 and the contact ball 33. The base plate 35 is fixedly installed at the bottom of the sliding rod 32. After the fuel burns, it accumulates on the top of the lower plate 17. The ash will be discharged downward through the slots of the lower plate 17 into the inside of the collection box 13. However, some of the ash will adhere to the inner wall of the slots of the lower plate 17, causing blockage of the lower plate 17. When the pusher frame 29 rotates, the pusher frame 29 will abut against the contact ball 33. 3. The contact ball 33 drives the sliding rod 32 to slide downward on the inner wall of the pentagonal rod 31. The contact ball 33 is elastic under the spring 34. After the contact ball 33 releases the contact of the pusher frame 29, it resets upward. The bottom plate 35 can limit the length of the sliding rod 32 to reset upward. The up and down movement of the contact ball 33 can clear the ash and slag attached to the slot of the lower plate 17, prevent the lower plate 17 from being blocked, improve the operating efficiency and stability of the boiler, and also reduce the burden of maintenance work.

[0033] In the operation of this utility model, a longitudinally arranged semi-gasification biomass gasification boiler accumulates on the top of the lower rack 17 after fuel combustion. Ash and slag are discharged downwards through the slots of the lower rack 17 into the collection box 13. However, some ash and slag adhere to the inner wall of the slots of the lower rack 17, causing blockage. When the pusher frame 29 rotates, it abuts against the abutting ball 33. The abutting ball 33 drives the sliding rod 32 to slide downwards on the inner wall of the pentagonal rod 31. Under the elasticity of the spring 2 34, the abutting ball 33 returns to its original position after releasing the abutting frame 29. The bottom plate 35 can limit the length of the sliding rod 32 to return to its original position. The up and down movement of the abutting ball 33 can clear the ash and slag adhering to the slots of the lower rack 17, preventing blockage and improving the boiler's operating efficiency and stability, while also reducing the burden of maintenance.
