DETAILED DESCRIPTION

[0036] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0037] Please refer to Figures 1-9 The present application provides a technical solution: a suspension combustion boiler, comprising a base 5, the base 5 is fixedly connected with a furnace body 1, the upper end of the furnace body 1 is provided with a feeding port 36, one side of the outer wall of the furnace body 1 is provided with an air blower 4, the air outlet end of the air blower 4 is communicated with the inner cavity of the furnace body 1, one side of the outer wall of the furnace body 1 is provided with an igniter 3, the ignition end of the igniter 3 penetrates through the furnace body 1 and extends into the inner cavity of the furnace body 1, one side of the upper end of the furnace body 1 is provided with a smoke pipe 2, and the upper end of the furnace body 1 is also provided with a granular fuel adding auxiliary assembly;

[0038] The granular fuel adding auxiliary assembly comprises a fixed shell 7 fixedly connected to one side of the upper end face of the furnace body 1, and the fixed shell 7 is provided with a discharging port 13 in the middle of the upper side and the lower side, the discharging port 13 is aligned with the feeding port 36, the feeding hopper 6 is fixedly connected and communicated at the upper side discharging port 13, a rotating shell 12 is rotatably arranged at one side of the inner cavity of the fixed shell 7, the outer wall of the rotating shell 12 is attached to the inner wall of the fixed shell 7, rotating rollers 38 are rotatably arranged in the grooves on both sides of the upper end of the rotating shell 12, bearing cloths 22 are wound on the rotating rollers 38, the bearing cloths 22 penetrate through one side of the grooves of the rotating shell 12, and the bearing cloths 22 can move in the grooves of the rotating shell 12 when the rotating rollers 38 rotate.

[0039] In this embodiment, as shown in Figures 6-8 One side of the support plate 19 is fixedly connected with an air cylinder 20, and the piston end of the air cylinder 20 is fixedly connected with one side of the bearing plate 14.

[0040] The motor seven 37 is fixedly connected to one side of the rotating shell 12 groove, and the output end of the motor seven 37 is fixedly connected to one end of the rotating roller 38.

[0041] The motor five 29 is fixedly connected to one side of the fixed shell 7 outer wall, and the output end of the motor five 29 is fixedly connected to the rotating shell 12.

[0042] Specifically, in the prior art, when the suspended combustion boiler is in use, the particle fuel is sent into the combustion chamber through the screw feeder, the air is delivered into the combustion chamber by the air blower 4, and then the particle fuel is ignited to produce a suspended combustion effect. However, the fuel distribution in the cavity of the screw feeder may not be uniform enough, which makes it difficult for the particle fuel to be discharged from the end of the screw feeder at a fixed rate. In some cases, it is necessary to control the amount of particle fuel added in real time according to the combustion condition. If the particle fuel cannot be added at a fixed rate, it will be inconvenient to accurately control the amount of fuel added, thereby affecting the combustion efficiency.

[0043] Therefore, in order to solve the above problems, in the use of the present embodiment, the particle fuel is added through the feeding hopper 6. Since the outer wall of the rotating shell 12 is attached to the inner wall of the fixed shell 7, and the rotating shell 12 is provided with a notch on one side, when the particle fuel contacts the outer wall of the rotating shell 12, the particle fuel will always stay in the inner cavity of the feeding hopper 6 due to the blockage of the outer wall of the rotating shell 12. And since the carrier plate 14 and the two side carrier cloths 22 cooperate to form a receiving groove at the notch of the rotating shell 12, when the motor five 29 drives the rotating shell 12 to rotate, the notch of the rotating shell 12 is aligned with the upper discharge port 13 of the fixed shell 7, the particle fuel in the inner cavity of the feeding hopper 6 will fall into the receiving groove due to the loss of support from the outer wall of the rotating shell 12, and when the rotating shell 12 continues to rotate, the particle fuel above the receiving groove still stays in the feeding hopper 6, and the rest of the particle fuel will move with the receiving groove, and during the movement of the receiving groove, the particle fuel inside the receiving groove will not move out due to the blockage of the inner wall of the fixed shell 7. When the receiving groove moves to the lower discharge port 13, the particle fuel will fall into the furnace body 1 from the feeding port 36, and then the air is delivered into the inner cavity of the furnace body 1 by the air blower 4, and the igniter 3 is operated to ignite, to produce a suspended combustion effect, and the flue gas generated by combustion is discharged from the smoke pipe 2.

[0044] During combustion, the above operation is repeated, so that the particle fuel can be intermittently added into the furnace body 1 according to the real-time combustion condition, and the carrier plate 14 can be moved by the air cylinder 20 to adjust the distance between the carrier plate 14 and the discharge port 13, and at the same time, the rotating roller 38 is driven by the motor seven 37 to rotate to wind or unwind the carrier cloth 22, so that the volume of the entire receiving groove can be adjusted. Therefore, when the receiving groove receives the particle fuel, the volume of the receiving groove is the amount of particle fuel added at a time, so that the accurate control of the amount of particle fuel added is realized, which is conducive to improving the combustion efficiency.

[0045] In the present embodiment, asFigure 3 、 Figure 6 、 Figure 7 As shown in FIG. 1, the bottom side of the fixed shell 7 is provided with a scraping assembly;

[0046] The scraping assembly comprises a rack 9 slidingly connected to the bottom side of the outer wall of the fixed shell 7, and the end of the rack 9 is fixedly connected with a scraper 8, and the side edge of the scraper 8 is attached to the outer wall of the fixed shell 7.

[0047] A gear 11 is rotatably arranged on the bottom side of the outer wall of the fixed shell 7, and the gear 11 is engaged with the tooth blocks on the rack 9, and a motor 10 is fixedly connected to the bottom side of the outer wall of the fixed shell 7, and the output end of the motor 10 is fixedly connected with the gear 11.

[0048] The support plate 19 is also provided with an auxiliary falling assembly;

[0049] The auxiliary falling assembly comprises a reciprocating rod 21 slidingly connected to the upper end surface of the support plate 19, and the end of the reciprocating rod 21 is fixedly connected with a squeezing roller 28.

[0050] One end of the reciprocating rod 21 is rotatably provided with a connecting rod 17, one end of the connecting rod 17 is rotatably provided with an adjusting block 15, one side of the adjusting block 15 is threadedly connected with a threaded rod 16, one end of the threaded rod 16 is rotatably arranged on the support plate 19, and the other end is rotatably arranged on the rotating shell 12, and one side of the support plate 19 is fixedly connected with a motor 18, and the output end of the motor 18 is fixedly connected with one end of the threaded rod 16.

[0051] Specifically, in the above embodiment, although the material receiving groove composed of the bearing plate 14 and the bearing cloth 22 can be used to receive the material, when the granular fuel is discharged from the material receiving groove, it may be attached to the surface of the bearing plate 14 and the bearing cloth 22 due to viscosity, thereby causing part of the granular fuel to not be completely added into the furnace body 1, and further affecting the addition amount and combustion efficiency of the granular fuel;

[0052] Therefore, in order to solve the above problems, when the material receiving groove is aligned with the lower side of the material falling port 13 during use, the cylinder 20 drives the bearing plate 14 to move, so that the bearing plate 14 approaches the lower side of the material falling port 13, and at the same time, the bearing cloth 22 is also being wound, and during the winding of the bearing cloth 22, the motor 18 drives the threaded rod 16 to rotate, and through the adjusting block 15, the two connecting rods 17 on both sides are driven to rotate, so that the two reciprocating rods 21 reciprocate, and then the squeezing roller 28 at the end of the reciprocating rod 21 can be used to knock the bearing cloth 22, so that the bearing cloth 22 vibrates, and the granular fuel is caused to fall off from the surface of the bearing cloth 22. Since the movement of the squeezing roller 28 and the winding of the bearing cloth 22 are carried out at the same time, the squeezing roller 28 can knock the bearing cloth 22 at various positions, thereby improving the uniformity of the knocking, and avoiding the granular fuel from being attached to the surface of the bearing cloth 22.

[0053] And, when the bearing plate 14 is attached to the edge of the drop port 13, the lower drop port 13 is filled by the bearing plate 14, at this time, the gear 11 is driven to rotate by the motor 10, the rack 9 is slid on the surface of the fixed shell 7, and the scraper 8 makes a circular motion around the outer wall of the fixed shell 7, so that the scraper 8 and the surface of the bearing plate 14 form scraping, and the particles adhering to the surface of the bearing plate 14 are scraped off. At this time, the removal of the particles adhering to the surface of the bearing plate 14 and the carrying cloth 22 is realized, and the situation that the particles adhere to the surface of the bearing plate 14 and the carrying cloth 22 due to viscosity when the particles are discharged from the receiving groove, resulting in that part of the particles cannot be completely added into the furnace body 1, thereby affecting the adding amount and combustion efficiency of the particles, is avoided.

[0054] In the embodiment, as shown in Figure 4 and Figure 9 The bearing plate 14 is also provided with a cooperative cutting assembly.

[0055] The cooperative cutting assembly comprises a rotating cylinder 23 slidably connected to both sides of the bearing plate 14, a threaded block 24 rotatably arranged at the lower end of the rotating cylinder 23, a displacement rod 35 slidably connected to both sides of the inner cavity wall of the rotating cylinder 23, a plurality of blades 31 fixedly connected to one side of the displacement rod 35, and the blades 31 are insertedly and slidably connected with the rotating cylinder 23.

[0056] A motor three 25 is fixedly connected to one side of the lower end surface of the threaded block 24, the output end of the motor three 25 is fixedly connected with the bottom of the rotating cylinder 23, a threaded rod two 27 is threadedly connected to one side of the threaded block 24, one end of the threaded rod two 27 is rotatably arranged on the bearing plate 14, a motor four 26 is fixedly connected to one side of the bottom of the bearing plate 14, the output end of the motor four 26 is fixedly connected with one end of the threaded rod two 27, a connecting rod two 34 is rotatably arranged at one end of the displacement rod 35, a lifting block 33 is rotatably arranged at one end of the connecting rod two 34, a threaded rod three 32 is threadedly connected to one side of the lifting block 33, both ends of the threaded rod three 32 are rotatably arranged in the inner cavity of the rotating cylinder 23, a motor six 30 is fixedly connected to one side of the inner cavity of the rotating cylinder 23, the output end of the motor six 30 is fixedly connected with one end of the threaded rod three 32.

[0057] Specifically, in the above embodiment, although the receiving groove can be used to receive the particles, part of the particles may be in the form of agglomerates, and during subsequent combustion, the particles may not be completely combusted, affecting the combustion effect;

[0058] Therefore, in order to solve the above problems, when the bearing plate 14 is used to receive the granular fuel, according to the height of the bearing plate 14 at this time, the threaded rod two 27 is driven by the motor four 26 to rotate, so that the threaded block 24 and the rotating cylinder 23 are lifted, the height of the upper end of the rotating cylinder 23 is adjusted, and the rotating cylinder 23 is lower than the upper edge of the receiving groove, so that when the rotating shell 12 rotates, the rotating cylinder 23 will not collide with the fixed shell 7, and when the receiving groove is moved away from the upper side of the material inlet 13, the threaded rod three 32 is driven by the motor six 30 to rotate, so that the lifting block 33 moves, and under the action of the connecting rod two 34, the displacement rod 35 slides on the inner wall of the rotating cylinder 23, so that the blade 31 moves out of the inner cavity of the rotating cylinder 23, at this time, the rotating cylinder 23 is driven by the motor three 25 to rotate, and the blade 31 is used to cut and crush the granular fuel in the receiving groove. At the same time, since the granular fuel is in the closed receiving groove, and the granular fuel in the receiving groove will roll when the receiving groove rotates, and cooperates with the movement of the bearing plate 14, the knocking of the bearing plate 22 by the squeezing roller 28, the granular fuel in the receiving groove can continuously move, so that the granular fuel in the receiving groove can be uniformly cut and crushed, and the caked granular fuel is dispersed, so that the incomplete combustion of the granular fuel during subsequent combustion is effectively avoided, and the combustion effect is affected. And when the granular fuel is discharged from the receiving groove, the blade 31 is retracted into the inner cavity of the rotating cylinder 23, and the rotating cylinder 23 moves longitudinally until the end is flush with one side of the bearing plate 14, so that the granular fuel attached to the blade 31 and the surface of the rotating cylinder 23 will fall off due to scraping, and the granular fuel will not be attached to the blade 31 and the surface of the rotating cylinder 23; and compared with the way of crushing the granular fuel before adding the granular fuel, this crushing method is coordinated with the batch adding of the granular fuel, and is crushed batch by batch, which is beneficial to improve the crushing effect.

[0059] Working principle: The granular fuel is added through the feeding hopper 6. Since the outer wall of the rotating shell 12 is attached to the inner wall of the fixed shell 7, and the rotating shell 12 is provided with a notch on one side, when the granular fuel contacts the outer wall of the rotating shell 12, the granular fuel will always stay in the inner cavity of the feeding hopper 6 due to the blocking of the outer wall of the rotating shell 12. And because the bearing plate 14 and the two sides of the bearing cloth 22 cooperate to form a receiving groove at the notch of the rotating shell 12, when the motor 29 drives the rotating shell 12 to rotate, the notch of the rotating shell 12 is aligned with the upper discharge port 13 of the fixed shell 7, the granular fuel in the inner cavity of the feeding hopper 6 will fall into the receiving groove due to the loss of support from the outer wall of the rotating shell 12. When the rotating shell 12 continues to rotate, the granular fuel above the receiving groove still stays in the feeding hopper 6, and the remaining granular fuel will move with the receiving groove, and during the movement of the receiving groove, the granular fuel inside the receiving groove will not move out due to the blocking of the inner wall of the fixed shell 7. When the receiving groove moves to the lower discharge port 13, the granular fuel will fall into the furnace body 1 from the feeding port 36, then the air is sent into the inner cavity of the furnace body 1 by the air blower 4, and the igniter 3 performs ignition operation, producing a suspended combustion effect. The flue gas produced by combustion will be discharged from the smoke pipe 2. During combustion, the above operation is repeated, so that the granular fuel can be added intermittently into the furnace body 1 according to the real-time combustion condition, and the distance between the bearing plate 14 and the discharge port 13 can be adjusted by moving the bearing plate 14 driven by the air cylinder 20, at the same time, the volume of the entire receiving groove can be adjusted by winding and unwinding the bearing cloth 22 driven by the motor 37 and the rotating roller 38, so that the volume of the receiving groove is the amount of granular fuel added at a time when the receiving groove is receiving, thereby realizing precise control of the amount of granular fuel added, which is conducive to improving the combustion efficiency. When the receiving groove is aligned with the lower discharge port 13, the bearing plate 14 is moved by the air cylinder 20, so that the bearing plate 14 approaches the lower discharge port 13, at the same time, the bearing cloth 22 is also being wound, during the winding of the bearing cloth 22, the screw rod 16 is rotated by the motor 18, the two side connecting rods 17 are rotated by the adjusting block 15, and the two reciprocating rods 21 are reciprocated, so that the extrusion roller 28 at the end of the reciprocating rod 21 can knock the bearing cloth 22 to make the bearing cloth 22 vibrate, and the granular fuel can be shaken off from the surface of the bearing cloth 22. Since the movement of the extrusion roller 28 and the winding of the bearing cloth 22 are carried out at the same time, the extrusion roller 28 can knock the bearing cloth 22 at various positions, thereby improving the uniformity of knocking and avoiding the granular fuel adhering to the surface of the bearing cloth 22. And when the bearing plate 14 is attached to the edge of the discharge port 13, the lower discharge port 13 is filled by the bearing plate 14, at this time, the gear 11 is rotated by the motor 10, the gear 11 drives the rack 9 to slide on the surface of the fixed shell 7, and the scraper 8 makes a circular motion around the outer wall of the fixed shell 7, so that the scraper 8 and the surface of the bearing plate 14 form a scraping, and the granular fuel adhering to the surface of the bearing plate 14 is scraped off.At this point, the removal of the particles fuel attached to the surface of the carrier plate 14 and the carrier cloth 22 is achieved, avoiding the situation that the particles fuel attached to the surface of the carrier plate 14 and the carrier cloth 22 due to viscosity when the particles fuel is discharged from the receiving groove, resulting in that part of the particles fuel cannot be completely added into the furnace body 1, thereby affecting the adding amount and combustion efficiency of the particles fuel. When the carrier plate 14 receives the particles fuel, according to the height of the carrier plate 14 at this time, the threaded rod two 27 is driven to rotate by the motor four 26, so that the threaded block 24 and the rotating cylinder 23 are lifted and lowered, the height of the upper end of the rotating cylinder 23 is adjusted, and the rotating cylinder 23 is lower than the upper edge of the receiving groove, so that when the rotating shell 12 rotates, the rotating cylinder 23 will not collide with the fixed shell 7. When the receiving groove is moved away from the upper side of the feeding port 13, the threaded rod three 32 is driven to rotate by the motor six 30, so that the lifting block 33 moves and drives the displacement rod 35 to slide on the inner wall of the rotating cylinder 23 under the action of the connecting rod two 34, so that the blade 31 moves out of the inner cavity of the rotating cylinder 23. At this time, the rotating cylinder 23 is driven to rotate by the motor three 25, and the particles fuel in the receiving groove is cut and crushed by the blade 31. At the same time, since the particles fuel is in the closed receiving groove, and the particles fuel in the receiving groove will roll when the receiving groove rotates, and the particles fuel in the receiving groove can move continuously under the cooperation of the movement of the carrier plate 14 and the knocking of the squeezing roller 28 on the carrier cloth 22, so that the particles fuel in the receiving groove can be uniformly cut and crushed under the cooperation of multiple structures, so that the caked particles fuel is dispersed, thereby effectively avoiding the situation that the particles fuel is not completely burned during subsequent combustion, affecting the combustion effect. And when the particles fuel is discharged from the receiving groove, the blade 31 is retracted into the inner cavity of the rotating cylinder 23, and the rotating cylinder 23 moves longitudinally until the end thereof is flush with one side of the carrier plate 14, so that the particles fuel attached to the surface of the blade 31 and the rotating cylinder 23 will fall off due to scraping, and the particles fuel will not be attached to the surface of the blade 31 and the rotating cylinder 23. Compared with the method of crushing the particles fuel before adding the particles fuel, this crushing method is coordinated with the batch adding of the particles fuel, and the particles fuel is crushed batch by batch, which is beneficial to improve the crushing effect.
