Description

Technical Field

[0001] This invention relates to the field of biomass boiler fuel addition technology, specifically to a biomass boiler capable of automatic fuel addition. Background Technology

[0002] Biomass boilers are a type of boiler that uses biomass energy as fuel. They are classified into biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, vertical biomass boilers, and horizontal biomass boilers. They can be widely used in industries such as textiles, printing and dyeing, and food processing. In addition, fuel needs to be continuously added to the boiler during use.

[0003] According to patent number CN218154305U, an automatic biomass boiler fuel adding device is disclosed. Its structure includes a storage tank and a metering mechanism. Biomass fuel pellets are fed into the storage tank through the feed inlet. Then, during the metered and timed output, the drive motor drives the rotating shaft to rotate the screw pusher to feed the biomass fuel pellets into the receiving trough inside the rotating drum.

[0004] While this automatic biomass boiler fuel adding device can add biomass fuel pellets in a timely and quantitative manner, resulting in more stable boiler combustion and reduced energy consumption, it cannot achieve automatic fuel addition. Therefore, this technical solution needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a biomass boiler that can automatically add fuel, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a biomass boiler that can automatically add fuel, including a support column, a feeding mechanism fixedly connected to the top of the support column, a dustproof mechanism fixedly connected to the top of the feeding mechanism, and a receiving box provided at the bottom of the inside of the support column; The feeding mechanism includes a material control component and a material dispensing component, wherein the material dispensing component is disposed on the front side of the material control component; The dustproof mechanism includes a supporting top plate, which is fixedly connected to the top of the material control assembly. A dustproof seat is fixedly connected to the top of the supporting top plate. A second spring is fixedly connected to the top left end of the dustproof seat. A locking rod is fixedly connected to the top of the second spring. A pull block is fixedly connected to the top of the locking rod. A dustproof plate is provided inside the dustproof seat. Long slides are fixedly connected to both ends of the surface of the dustproof plate. A pull plate is fixedly connected to the left end of the long slide.

[0007] According to the above technical solution, the material control component includes a supporting long base plate, which is fixedly connected to the top of the support column. A feeding box is fixedly connected to the top of the supporting long base plate. Connecting blocks are fixedly connected to the front and rear ends of the feeding box, respectively. A first spring is fixedly connected to the top of the connecting block, and a connecting top block is fixedly connected to the top of the first spring. A support rod is fixedly connected to the bottom of the connecting top block. A telescopic channel is fixedly connected to the bottom of the supporting long base plate, and a connecting long plate is fixedly connected to the bottom end of the telescopic channel. A material handling box is fixedly connected to the bottom end of the connecting long plate, and the bottom of the supporting top plate is fixedly connected to the top of the feeding box.

[0008] According to the above technical solution, there are two support rods and two connecting blocks. A through hole is opened in the middle of the connecting block. The surfaces of the two support rods pass through the through holes opened in the middle of the two connecting blocks respectively. When the material inside the feed box decreases, causing the support rods and connecting top blocks on both sides of the connecting plate to move upward under the elastic action of the first spring, the surface of the first spring can move upward under the support and limiting action of the through hole opened in the middle of the connecting block, and drive the telescopic channel to lengthen, thereby providing support and stability for the material feeding box.

[0009] According to the above technical solution, openings are provided at the bottom of the feeding box and the left end of the surface of the supporting long base plate, and openings are provided in the middle of the connecting long plate and the inside of the material conveying box. The inside of the material conveying box and the inside of the feeding box are connected through the openings in the middle of the connecting long plate and the left end of the surface of the supporting long base plate.

[0010] According to the above technical solution, the feeding assembly includes a support roller, which is rotatably connected to the inside of the feeding box. A feeding slide is fixedly connected to the surface of the support roller. A rotating plate is fixedly connected to one end of the front of the support roller. A T-shaped block is provided inside the rotating plate. A support round seat is fixedly connected to the front of the T-shaped block. An I-shaped round block is provided inside the support round seat. An L-shaped strip is fixedly connected to the front of the I-shaped round block. The bottom left end of the L-shaped strip is fixedly connected to the right side of the connecting long plate.

[0011] According to the above technical solution, a through hole is provided in the middle of the front of the feeding box, and the surface of the support roller passes through the through hole in the middle of the front of the feeding box. One end of the back of the support roller is rotatably connected to the back of the inside of the feeding box. When feeding, fuel is put into the feed box through the feeding box. Then, the feed box is filled with too much fuel, which causes the feed box to be driven by gravity to move the connecting plate downward, and drive the L-shaped strip, the I-shaped block, the support seat and the T-shaped block to move downward. When the rotating plate rotates, it can drive the support roller at one end of the rotating plate to drive the feeding slide to rotate, and cause the left end of the feeding slide to tilt upward, so that the feeding slide is in a horizontal state and prevents the fuel on the feeding slide from falling, thereby enabling automatic fuel addition.

[0012] According to the above technical solution, a T-shaped groove is provided on the front side of the rotating plate, and the surface of the T-shaped block is slidably connected to the inside of the T-shaped groove.

[0013] According to the above technical solution, the supporting circular seat has a circular cavity inside, and an opening is formed in the middle of the front of the circular cavity. The surface of the I-shaped circular block is rotatably connected to the inside of the circular cavity. A groove is formed in the middle of the surface of the I-shaped circular block, and the groove in the middle of the surface of the I-shaped circular block is located inside the opening. When the L-shaped strip drives the rotating plate to flip, the L-shaped strip drives the I-shaped circular block and allows it to rotate under the limiting support inside the supporting circular seat. This also drives the T-shaped block at one end of the supporting circular seat to rotate in the T-shaped groove formed on the front of the rotating plate, thereby driving the rotating plate to flip.

[0014] According to the above technical solution, a slot is provided inside the supporting top plate, and an opening is provided on the left side of the slot. There are two long slide bars, and the surfaces of the two long slide bars are respectively located inside the slots provided in the supporting top plate.

[0015] According to the above technical solution, an opening is provided at the top left end of the dustproof seat, and through holes are provided at the left ends of the dustproof plate surface and the long slide bar surface. The surface of the locking rod passes through the opening at the top left end of the dustproof seat, and the surface of the locking rod also passes through the through holes at the left ends of the dustproof plate surface and the long slide bar surface. When using the dustproof plate for dust prevention, when the dustproof plate and the long slide bar are inserted into the slots inside the dustproof seat, when they move to align with the through holes at the left ends of the dustproof plate surface and the long slide bar surface and the opening at the top left end of the dustproof seat, the locking rod can be inserted downwards into the dustproof plate and the long slide bar under the elastic action of the second spring, thereby installing and fixing the dustproof plate and achieving a certain dust prevention effect. In addition, when pulling out, the dustproof plate can be easily pulled out from inside the dustproof seat by pulling the pull plate, which facilitates cleaning the surface of the dustproof plate and adding fuel to the feed box.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: This biomass boiler with automatic fuel addition, through its feeding mechanism, allows the support rods and connecting top block on both sides of the connecting plate to move upward under the elastic action of the first spring when the material inside the feeding box decreases. This movement is supported and limited by the through hole in the middle of the connecting block, which in turn stretches the telescopic channel, thus providing support and stability for the feeding box.

[0017] This biomass boiler with automatic fuel addition works by using a feeding mechanism. When there is too much fuel in the feed box, the feed box is driven by gravity to move the connecting plate downwards, which in turn moves the L-shaped bar, I-shaped block, support seat, and T-shaped block downwards. When the rotating plate rotates, it can drive the support roller at one end of the rotating plate to rotate the feed slide, causing the left end of the feed slide to tilt upwards, thus changing the feed slide to a horizontal state and preventing the fuel on the feed slide from falling. This allows for automatic fuel addition.

[0018] This biomass boiler, which can automatically add fuel, uses a feeding mechanism. When the L-shaped bar drives the rotating plate to flip, the L-shaped bar drives the I-shaped block to rotate under the limiting support inside the support round seat. This causes the T-shaped block at one end of the support round seat to rotate in the T-shaped groove on the front of the rotating plate, thereby driving the rotating plate to flip.

[0019] This biomass boiler with automatic fuel addition features a dustproof mechanism. Under the elastic action of the second spring, the lever can be inserted downwards into the dustproof plate and long slide bar to install and fix the dustproof plate, thus providing a certain dustproof effect. In addition, when pulling out, the dustproof plate can be easily pulled out from inside the dustproof seat by pulling the pull plate, which facilitates cleaning the surface of the dustproof plate and adding fuel to the feed box.

A feed box 219 is fixedly connected to the bottom of the connecting long plate 218. The bottom of the supporting top plate 31 is fixedly connected to the top of the feed box 212. There are two support rods 215 and two connecting blocks 213. A through hole is opened in the middle of the connecting block 213. The surfaces of the two support rods 215 pass through the through holes opened in the middle of the two connecting blocks 213.

[0025] Furthermore, openings are provided at the bottom of the feed box 212 and the left end of the surface of the supporting long base plate 211. Openings are also provided in the middle of the connecting long plate 218 and the inside of the feed box 219. The inside of the feed box 219 and the inside of the feed box 212 are connected through the openings in the middle of the connecting long plate 218 and the left end of the surface of the supporting long base plate 211. When the material inside the feed box 219 decreases, causing the support rods 215 and the connecting top block 216 on both sides of the connecting long plate 218 to move upward under the elastic action of the first spring 214, the surface of the first spring 214 can move upward under the support and limiting action of the through hole in the middle of the connecting block 213, and drive the telescopic channel 217 to lengthen, thereby providing support and stability for the feeding of the feed box 212. Example 2

[0026] See Figure 1-6Furthermore, based on Embodiment 1, the feeding assembly 22 further includes a support roller 221, which is rotatably connected to the inside of the feeding box 212. A feeding slide 222 is fixedly connected to the surface of the support roller 221. A rotating plate 223 is fixedly connected to one end of the front of the support roller 221. A T-shaped block 224 is provided inside the rotating plate 223. A support round seat 225 is fixedly connected to the front of the T-shaped block 224. An I-shaped round block 226 is provided inside the support round seat 225. An L-shaped strip 227 is fixedly connected to the front of the I-shaped round block 226. The bottom left end of the L-shaped strip 227 is fixedly connected to the right side of the connecting long plate 218. A through hole is opened in the middle of the front of the feeding box 212. The surface of the support roller 221 passes through the through hole opened in the middle of the front of the feeding box 212. One end of the back of the support roller 221 is rotatably connected to the back of the inside of the feeding box 212. A T-shaped groove is opened on the front of the rotating plate 223. The surface of the T-shaped block 224 is slidably connected to the inside of the T-shaped groove.

[0027] Furthermore, the support round base 225 has a cavity inside, with an opening in the center of the front of the cavity. The I-shaped round block 226 is rotatably connected to the cavity on its surface. The I-shaped round block 226 has a groove in the center of its surface, which is located inside the opening. When there is too much fuel inside the feed box 219, the feed box 219 is driven by gravity to move the connecting long plate 218 downward, which in turn drives the L-shaped strip 227, the I-shaped round block 226, the support round base 225, and the T-shaped block 224 downward. When this causes the rotating plate 223 to rotate, it can drive the support roller 221 at one end of the rotating plate 223. The feed chute 222 is rotated, and the left end of the feed chute 222 is tilted upward, causing the feed chute 222 to be in a horizontal state, preventing the fuel on the feed chute 222 from falling, thereby enabling automatic fuel addition. When the L-shaped bar 227 drives the rotating plate 223 to flip, the L-shaped bar 227 drives the I-shaped block 226 to rotate under the limiting support inside the support round seat 225, and drives the T-shaped block 224 at one end of the support round seat 225 to rotate in the T-shaped groove opened on the front of the rotating plate 223, thereby driving the rotating plate 223 to flip. Example 3

[0028] See Figure 1-6 Furthermore, based on Embodiment 1, the support top plate 31 has a slot inside, an opening on the left side of the slot, two long slide bars 35, the surfaces of the two long slide bars 35 are respectively located inside the slots opened in the support top plate 31, the dustproof seat 32 has an opening at the top left end, the dustproof plate 36 and the long slide bar 35 have through holes at the left end of their surfaces, the locking rod 34 passes through the opening at the top left end of the dustproof seat 32, and the locking rod 34 also passes through the through holes at the left end of the dustproof plate 36 and the long slide bar 35.

[0029] Furthermore, under the elastic action of the second spring 33, the lever 34 can be inserted downwards into the dustproof plate 36 and the long slide bar 35 to install and fix the dustproof plate 36 and provide a certain dustproof effect. In addition, when pulling out, the dustproof plate 36 can be easily pulled out from the dustproof seat 32 by pulling the pull plate 37, which facilitates cleaning the surface of the dustproof plate 36 and adding fuel to the feed box 212.

[0030] In actual operation, when this device is used, a certain amount of fuel is first stored inside the feed box 212. During feeding, the fuel is fed into the feed box 219 through the feed box 212. Then, when there is too much fuel in the feed box 219, the feed box 219 is driven by gravity to move the connecting plate 218 downward, which in turn drives the L-shaped bar 227, the I-shaped block 226, the support seat 225, and the T-shaped block 224 downward. When the rotating plate 223 rotates, it can drive the support roller 221 at one end of the rotating plate 223 to drive the feed slide 222 to rotate, and cause the left end of the feed slide 222 to rotate. The upward tilting of the feed chute 222 causes it to be in a horizontal position, preventing fuel from falling off the feed chute 222 and enabling automatic fuel addition. When the material inside the feed box 219 decreases, causing the support rods 215 and the connecting top block 216 on both sides of the connecting plate 218 to move upward under the elastic action of the first spring 214, the surface of the first spring 214 can move upward under the support and limiting action of the through hole in the middle of the connecting block 213, and drive the telescopic channel 217 to lengthen, thereby providing support and stability for the material discharge from the feed box 212. When the L-shaped bar 227 drives the rotating plate 223 to rotate, the L-shaped bar 227 drives the I-shaped block 226 to rotate under the limiting support inside the supporting round seat 225, and drives the T-shaped block 224 at one end of the supporting round seat 225 to rotate in the T-shaped groove opened on the front of the rotating plate 223, thereby driving the rotating plate 223 to rotate. When using the dustproof plate 36 for dustproof operation, when the dustproof plate 36 and the long slide bar 35 are inserted into the slot opened inside the dustproof seat 32, when it moves to the left end of the surface of the dustproof plate 36 and the long slide bar When the through hole on the left end of surface 35 is aligned with the opening on the top left end of dustproof seat 32, the locking rod 34 can be inserted downward into the dustproof plate 36 and the long slide bar 35 under the elastic action of the second spring 33, thereby performing the installation and fixing operation of dustproof plate 36 and providing a certain dustproof effect. In addition, when pulling out, the dustproof plate 36 can be easily pulled out from inside the dustproof seat 32 by pulling the pull plate 37, which facilitates the cleaning of the surface of dustproof plate 36 and the addition of fuel to the feed box 212.
