Description

Technical Field

[0001] The present invention relates to the technical field of energy utilization, and in particular to a biomass boiler. Background Art

[0002] During the operation of traditional biomass boilers, biomass fuel may accumulate when it is added to the boiler, or be affected by various factors during the combustion process, causing the fuel to accumulate in a specific area inside the boiler. This phenomenon will not only cause the fuel to form ash after combustion and accumulate inside the fuel pile, but also cause the fuel to easily form fuel agglomerates due to accumulation. At the same time, fuel agglomerates will hinder the contact between air and the inside of the fuel, resulting in incomplete combustion of the fuel. In addition, due to the accumulation of ash, some gaps will be formed, which further leads to low thermal conductivity of the fuel, making some fuel unable to be ignited or low combustion efficiency. The agglomerated fuel also significantly increases the difficulty and frequency of cleaning the boiler, which is not conducive to boiler maintenance and operation efficiency.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Reference Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a biomass boiler, comprising a biomass boiler body 1, a controller 2 is installed on one side of the biomass boiler body 1, a discharge door 3 is installed on one side of the biomass boiler body 1, a feed pipe 4 is fixedly connected to the top of the biomass boiler body 1, mounting frames 5 are installed on both sides of the biomass boiler body 1, and mixing components are installed inside the two mounting frames 5; Mixing components include: The sleeve 6 has a toothed disc 7 fixedly connected to its surface, and the bottom of the mounting frame 5 is fixedly connected to a drive motor 8. The output end of the drive motor 8 is meshed with the surface of the toothed disc 7 through a gear. A transmission rod 9 is installed inside the sleeve 6. The transmission rod 9 is fixedly connected to a long shell 10 on the side close to the biomass boiler body 1. The inner diameter of the biomass boiler body 1 is provided with a digging hopper 11, and the surface of the digging hopper 11 has a plurality of holes. A stirring assembly is used to make the digging hopper 11 revolve along the inner wall of the biomass boiler body 1, and to deflect the digging hopper 11 during the process of the digging hopper 11 revolving; The screening component is connected to the stirring component in a transmission manner to drive the transmission rod 9 to move forward and backward; The adjusting component is arranged on one side of the transmission rod 9 to adjust the forward and backward movement speed of the transmission rod 9. When the material is burned inside the biomass boiler body 1 through the provided mixing component, the fuel in the biomass boiler body 1 is stirred by using the hopper 11, and the material is driven to be evenly poured into the biomass boiler body 1. At the same time, the ash and solid fuel in the fuel are screened to increase the contact area between the fuel and the air, thereby avoiding the accumulation of ash in one place to affect the fuel combustion quality, thereby improving the combustion efficiency of the biomass boiler body 1 during operation.

[0019] Reference Figure 1 - Figure 8 As shown, in this embodiment, the stirring component includes: The square shell 12 is slidably connected to the inside of the long shell 10. Two slots 13 are provided on one side of the square shell 12. Both sides of the square shell 12 are fixedly connected with slide bars 14. The surface of the slide bar 14 is slidably connected to the long shell 10. The end of the left slide bar 14 away from the square shell 12 is fixedly connected to the shell 16. The inside of the shell 16 is rotatably connected with a special-shaped tooth plate 17. The inner wall of the long shell 10 is fixedly connected to two extension plates 18. The inner wall of the square shell 12 is slidably connected with a slide plate 19. The surface of the slide plate 19 is fixedly connected to a long rod 21. The long rod 21 is slidably connected to the inside of the slide bar 14. The surface of the slide plate 19 is fixedly connected to two first springs 20. The other end of the first spring 20 is fixedly connected to the inner wall of the square shell 12. When the material is accumulated inside the biomass boiler body 1 During combustion, the staff operates the manipulator 2 to start the drive motor 8, so that the drive motor 8 drives the transmission rod 9 to rotate through the gear plate 7, and then the transmission rod 9 drives the long shell 10 to rotate. Through the rotation of the long shell 10, the left and right slide bars 14 are driven to rotate close to the inner diameter of the biomass boiler body 1. At the same time, the rotation center point of the long shell 10 is placed at the bottom position of the center point of the biomass boiler body 1. When the long shell 10 rotates itself, the slide bar 14 slides with the long shell 10 and the slide bar 14, so that the slide bar 14 can slide along the long shell 10 with the square shell 12 as the center point, so that when the long shell 10 rotates, the slide bar 14 can follow the long shell 10 to rotate and adjust the position of the square shell 12 placed inside the long shell 10, so that the slide bar 14 rotates eccentrically. At the same time, the digging hopper 11 is always close to the inner diameter of the biomass boiler body 1. When the long shell 10 drives the slide rod 14 to rotate the slide rod 14, the slide rod 14 can dig up the material inside the biomass boiler body 1, so that the material is placed inside the digging hopper 11 and rotates upward. When the long shell 10 rotates to a certain angle, the slide rod 14 and the digging hopper 11 are in an inclined state. At this time, part of the material in the digging hopper 11 will tilt downward and fall. When the long shell 10 rotates to a specified angle, the square shell 12 will gradually move upward along the inside of the long shell 10, so that the extension plate 18 is gradually inserted into the slot 13, and tilted downward to push the slide plate 19 to squeeze the first spring 20 to contract. At the same time, the slide plate 19 will drive the long rod 21 to slide to one side, so that the long rod 21 is close to one end of the slide plate 19 When the hopper 11 is rotated to the right side of the top of the biomass boiler body 1, the extension plate 18 will gradually move away from the slide plate 19 and be pulled out from the inside of the slot 13. At the same time, the first spring 20 will release the force generated.The push slide 19 drives the long rod 21 and the long tooth plate 22 to move to one side of the shell 16, so that the long tooth plate 22 pushes the special-shaped tooth plate 17 in the opposite direction to transmit it to the digging hopper 11 for rotation, so that the digging hopper 11 gradually rotates in the opposite direction to reset when the self-deflection rotation angle is at the right side position of the biomass boiler body 1. The digging hopper 11 is in a gradually tilted state on the right side of the biomass boiler body 1, and then the remaining materials dug out from the digging hopper 11 continue to tilt, so that the materials inside the biomass boiler body 1 can be evenly distributed left and right, thereby avoiding the accumulation of materials in the middle of the inner wall of the biomass boiler body 1, which causes the air inside the accumulated materials to be unable to circulate and affect the combustion efficiency. This design not only ensures the uniform distribution of fuel in the biomass boiler body 1, but also promotes the circulation of air, effectively improving the combustion effect. In addition, during the rotation process, the digging hopper 11 scoops up and dumps the fuel, which can also moderately stir the material, further preventing the material from agglomerating and ensuring the continuous and stable operation of the biomass boiler body 1.

[0020] Reference Figure 1 - Figure 8 As shown, in this embodiment: the screening component includes: The bracket 24 is fixedly connected to the surface of the mounting frame 5. The top of the bracket 24 is fixedly connected to the housing 25. The inside of the bracket 24 is rotatably connected to the turntable 26. The surface of the turntable 26 is fixedly connected to the second spring 27. The outer side of the second spring 27 is provided with two rotary plates 28. The side of the bracket 24 close to the rotary plate 28 is fixedly connected to the rotary plate 28. The end of the transmission rod 9 close to the rotary plate 28 is fixedly connected to the rotary plate 28. The two rotary plates 28 are slidably connected. The opposite surfaces of the two rotary plates 28 are both arc-shaped inclined structures. When When the transmission rod 9 is in the state of self-rotation, the rotation of the transmission rod 9 drives the rotary plate 28 at the rear end to rotate and rotate along the surface of the rotary plate 28 fixed to the bracket 24. Through the inclined surface structure of the two rotary plates 28, the transmission rod 9 is pushed forward by the gradual separation between the inclined surfaces during rotation. At the same time, the transmission rod 9 pulls the second spring 27 to extend and store force. When the rotary plate 28 rotates out of position and pushes the transmission rod 9 forward, the second spring 27 can pull the transmission rod 9 to move relative to each other, reset the position of the transmission rod 9, and then through the rotation of the two rotary plates 28, the transmission rod 9 is pushed forward. The rotation contact realizes the forward movement of the transmission rod 9, and then the reset tension of the second spring 27 drives the transmission rod 9 to move backward, so that the transmission rod 9 repeatedly shakes back and forth during the rotation process, and then drives the long shell 10 through the transmission rod 9 to make the digging bucket 11 move back and forth repeatedly, so that the digging bucket 11 shakes back and forth, and the holes on the surface of the digging bucket 11 allow the fine ashes in the fuel to be screened out through the holes and the repeated movement of the digging bucket 11, thereby making the ashes in the fuel dug out inside the digging bucket 11 fall through the holes first. At the bottom of the inner wall of the biomass boiler body 1, the digging hopper 11 moves back and forth, driving the internal fuel to swing back and forth, so that the material inside the digging hopper 11 is flattened front and back and evenly distributed inside the digging hopper 11. When the digging hopper 11 is tilted, the material can be evenly scattered into the interior of the biomass boiler body 1 at the same horizontal plane, so that the material is flattened front and back inside the biomass boiler body 1, further avoiding the accumulation of materials affecting the combustion efficiency, and at the same time realizing the separation of the combustion ash of the material, avoiding most of the ash from accumulating in the unburned fuel.

[0021] Reference Figure 1 、 Figure 2 Figure 7 and Figure 8 As shown, in this embodiment: the regulating component includes: The electric push rod 29 is fixedly connected to the surface of the bracket 24. The output end of the electric push rod 29 passes through the bracket 24. The output end of the electric push rod 29 is fixedly connected to the I-plate 30. The I-plate 30 is rotatably connected to the inside of the turntable 26. The electric push rod 29 is connected to the wire of the manipulator 2 through the provided electric push rod 29, so that the manipulator 2 can control the start of the electric push rod 29 to run, thereby making the electric push rod 29 retract back and forth and drive the I-plate 30 to move back and forth. At the same time, when the I-plate 30 moves back and forth, it can pull the turntable 26 to move, and the turntable 26 is embedded in the I-plate 30 and is connected by a ball bearing. It does not affect the second spring 27 to rotate with the transmission rod 9 and can drive the I-plate 30 to control The front and rear positions of the turntable 26 enable the turntable 26 to stretch the second spring 27 when the electric push rod 29 drives the I-plate 30 to move backward, thereby increasing the reset tension of the second spring 27. When the electric push rod 29 drives the I-plate 30 to move forward, the turntable 26 relaxes the stretching of the second spring 27, causing the second spring 27 to reset under its own elastic action, thereby adjusting the reset force of the second spring 27, further promoting the forward and backward swing amplitude of the transmission rod 9 during the rotation process, and enhancing the screening effect of the hopper 11 on the ash in the fuel. This design not only improves the separation efficiency of ash and fuel, but also ensures the uniform distribution of fuel in the combustion chamber, optimizes the combustion process, and improves the overall combustion efficiency of the biomass boiler body 1.

[0022] Reference Figure 4 and Figure 5 As shown, in this embodiment: the surface of the special-shaped tooth plate 17 is fixedly connected with an arc plate 31, the thickness of the arc plate 31 is slightly larger than the outer diameter of the special-shaped tooth plate 17, and the arc plate 31 is provided so that the special-shaped tooth plate 17 is in a Figure 5 When the angle is medium, the rotation direction of the special-shaped tooth plate 17 is restricted by the arc plate 31, and the special-shaped tooth plate 17 cannot be deflected by the weight of the material carried by the digging bucket 11, so that the special-shaped tooth plate 17 can only rotate counterclockwise through the right movement of the long tooth plate 22 to drive the digging bucket 11 to self-deflect, so that the digging bucket 11 cannot reversely drive the special-shaped tooth plate 17 to rotate when it is in a horizontal state. At the same time, the initial position of the first spring 20 limits the position of the slide plate 19 and the long rod 21, and the first spring 20 can only be squeezed by the extension plate 18 on the slide plate 19 by the torque force of the rotation of the transmission rod 9 and the long shell 10 to shrink, thereby ensuring that the digging bucket 11 can stably rotate in one direction when screening the ash in the fuel, avoiding mechanical failure caused by reverse transmission.

[0023] Reference Figure 8As shown, in this embodiment: the inner wall of the toothed disc 7 is fixedly connected to the limiting blocks 32 on all sides, the surface of the sleeve 6 is provided with four long grooves 23, the surface of the arc plate 31 is slidably connected to the inner wall of the long groove 23, and the front and rear sliding connection between the limiting blocks 32 and the long groove 23 is used to make the drive motor 8 drive the toothed disc 7 so that the sleeve 6 rotates inside the mounting frame 5. The transmission rod 9 can be limited by the rotation of the limiting blocks 32 and the long groove 23, so that the sleeve 6 can drive the transmission rod 9 to rotate when it rotates. At the same time, the transmission rod 9 rotates through the thrust generated by the rotary plate 28, so that The transmission rod 9 can move back and forth repeatedly by sliding back and forth between the long slot 23 and the limit block 32, so that the transmission rod 9 can move back and forth repeatedly through the rotary plate 28, and at the same time can drive the transmission rod 9 to rotate by the sleeve 6, which not only enhances the stability of the transmission rod 9 during the rotation process, but also ensures that it can complete the reciprocating motion in the forward and backward directions while rotating. The thrust generated by the rotary plate 28 and the sliding connection between the limit block 32 and the long slot 23 form an efficient transmission mechanism, making the power transmission of the entire system smoother and more stable.

[0024] Reference Figure 3 、 Figure 4 and Figure 6 As shown, in this embodiment: the end of the right sliding rod 14 away from the square shell 12 is fixedly connected to a roller 15, and the roller 15 is slidably connected to the inner diameter of the biomass boiler body 1. When the sliding rod 14 rotates along the inside of the biomass boiler body 1 through the provided roller 15, the roller 15 can fit the inner diameter of the biomass boiler body 1 and roll and rotate, thereby reducing the friction between the sliding rod 14 and the biomass boiler body 1, and at the same time effectively forming a support for the right sliding rod 14 placed at the bottom position of the biomass boiler body 1. The rotation of the roller 15 can disperse and reduce the local pressure of the sliding rod 14 on the inner diameter of the biomass boiler body 1, avoiding the wear problem caused by long-term operation and extending the service life of the equipment. At the same time, the rotation of the roller 15 can also play a lubricating role to a certain extent, further reducing friction and kinetic energy loss during the rotation of the sliding rod 14.

[0025] Working principle: When the accumulated materials inside the biomass boiler body 1 are burned, the staff operates the controller 2 to start the drive motor 8, so that the drive motor 8 drives the transmission rod 9 to rotate through the gear plate 7, and then the transmission rod 9 drives the long shell 10 to rotate. Through the rotation of the long shell 10, the left and right sliding rods 14 are driven to rotate close to the inner diameter of the biomass boiler body 1, and at the same time, the rotation center point of the long shell 10 is placed at the bottom position of the center point of the biomass boiler body 1.

[0026] When the long shell 10 rotates by itself, the slide rod 14 can slide along the long shell 10 with the square shell 12 as the center point through the sliding of the long shell 10 and the slide rod 14, so that when the long shell 10 rotates, the slide rod 14 can rotate with the long shell 10 and adjust the position of the square shell 12 inside the long shell 10, so that the slide rod 14 rotates eccentrically, and at the same time, the digging hopper 11 is always close to the inner diameter of the biomass boiler body 1. When the long shell 10 drives the slide rod 14 to rotate the slide rod 14, the slide rod 14 can dig up the material inside the biomass boiler body 1, so that the material is placed inside the digging hopper 11 and rotates upward.

[0027] When the long shell 10 rotates to a certain angle, the slide bar 14 and the digging bucket 11 are in an inclined state. At this time, part of the material in the digging bucket 11 will tilt downward and fall. When the long shell 10 rotates to a specified angle, the square shell 12 will gradually move upward along the inside of the long shell 10, so that the extension plate 18 is gradually inserted into the inside of the slot 13, and tilts downward to push the slide plate 19 to squeeze the first spring 20 to contract. At the same time, the slide plate 19 will drive the long rod 21 to slide to one side, so that the end of the long rod 21 close to the slide plate 19 enters the square shell 1 2, the long tooth plate 22 is driven to slide to one side by the movement of the long rod 21, so that the long tooth plate 22 pulls the special-shaped tooth plate 17 to the right to rotate counterclockwise, thereby causing the special-shaped tooth plate 17 to drive the digging bucket 11 to self-deflect. When the digging bucket 11 rotates to the top of the inner diameter of the biomass boiler body 1, the inclination angle of the digging bucket 11 can be adjusted by self-deflection, so that the digging bucket 11 rotates at the top and gradually adjusts its horizontality during the rotation process, thereby being in a state relative to the horizontal state and no longer tilting to dump fuel.

[0028] When the digging hopper 11 rotates to the right side of the top position of the biomass boiler body 1 and continues to rotate, the extension plate 18 will gradually move away from the slide plate 19 and be pulled out to one side from the inside of the slot 13. At the same time, the first spring 20 will release the force generated, pushing the slide plate 19 to drive the long rod 21 and the long tooth plate 22 to move to one side of the shell 16, so that the long tooth plate 22 pushes the special-shaped tooth plate 17 in the opposite direction to transmit it to the digging hopper 11 for rotation, so that the digging hopper 11 gradually rotates in the opposite direction to reset when the self-deflection rotation angle is at the right side of the biomass boiler body 1. The digging hopper 11 is in a gradually tilted state on the right side of the biomass boiler body 1, and then continues to tilt the remaining materials dug up from the inside of the digging hopper 11, so that the materials inside the biomass boiler body 1 can be evenly distributed on the left and right.

[0029] When the transmission rod 9 is in the self-rotating state, the rotation of the transmission rod 9 drives the rotary plate 28 at the rear end to rotate and rotate along the surface of the rotary plate 28 fixed at the bracket 24. Through the inclined surface structure of the two rotary plates 28, the transmission rod 9 is pushed forward by gradually moving away from the inclined surfaces during rotation. At the same time, the transmission rod 9 pulls the second spring 27 to extend and store force. When the rotary plate 28 rotates out of position to push the transmission rod 9 forward, the second spring 27 can pull the transmission rod 9 to move against each other, reset the position of the transmission rod 9, and then realize the forward movement of the transmission rod 9 through the rotational contact of the two rotary plates 28, and then drive the transmission rod 9 to move backward through the reset tension of the second spring 27, realizing the transmission rod 9 to shake back and forth repeatedly during the rotation process, and then drive the long shell 10 through the transmission rod 9 to make the digging bucket 11 move back and forth repeatedly, realizing the shaking of the digging bucket 11 back and forth.

[0030] The holes on the surface of the digging hopper 11 allow the fine ashes in the fuel to be screened out through the holes and the repeated forward and backward movement of the digging hopper 11, thereby allowing the electric push rod 29 to retract forward and backward and drive the I-shaped plate 30 to move forward and backward. At the same time, when the I-shaped plate 30 moves forward and backward, it can pull the turntable 26 to move, and the turntable 26 is embedded in the inside of the I-shaped plate 30 and is connected by a ball bearing. It does not affect the second spring 27 that follows the transmission rod 9 to rotate and can drive the I-shaped plate 30 to control the forward and backward position of the turntable 26, so that when the electric push rod 29 drives the I-shaped plate 30 to move backward, the turntable 26 can stretch the second spring 27 and increase the reset tension of the second spring 27. When the electric push rod 29 drives the I-shaped plate 30 to move forward, the turntable 26 relaxes the second spring 27. The stretching of the spring 27 causes the second spring 27 to reset under its own elastic action, thereby realizing the adjustment of the reset force of the second spring 27. Through the front and rear sliding connection between the limit block 32 and the long slot 23, the drive motor 8 drives the gear plate 7 to rotate the sleeve 6 inside the mounting frame 5. The transmission rod 9 can be limited by the rotation of the limit block 32 and the long slot 23, so that the sleeve 6 can drive the transmission rod 9 to rotate when it rotates. At the same time, the thrust generated by the rotation of the transmission rod 9 through the rotary plate 28 allows the transmission rod 9 to slide back and forth through the long slot 23 and the limit block 32, and move back and forth repeatedly, thereby allowing the transmission rod 9 to move back and forth repeatedly through the rotary plate 28, and at the same time, it can drive the transmission rod 9 to rotate through the sleeve 6.
