Description

Technical Field

[0001] This utility model belongs to the field of fully combusted biomass technology, and in particular relates to a fully combusted biomass heating device. Background Technology

[0002] Biomass pellet burners play a crucial role in heating systems that fully combust biomass. They use biomass pellets as fuel, which are processed from agricultural and forestry waste, making them widely available and environmentally friendly. In terms of their working principle, biomass pellets enter a high-temperature pyrolysis semi-gasification combustion chamber via an automatic feeding system. The gasifying agent is supplied from the bottom, and the pellets rapidly undergo a high-temperature pyrolysis reaction to produce high-temperature fuel gas. This fuel gas then enters a high-temperature combustion chamber with sufficient oxygen for complete combustion, releasing a large amount of heat energy. This further ensures the complete combustion of the biomass pellets and efficiently provides the heat required for heating in various locations.

[0003] The problem with existing technology is that during the operation of existing biomass pellet burners, the biomass pellets in the hopper have poor mobility and are prone to accumulation at the bottom of the hopper due to their own gravity. This causes the pellets to fall poorly into the feed pipe, and even results in the phenomenon that the upper part of the pellets is stationary while the lower part is empty, which affects the timely supply of fuel. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a fully combusting biomass heating device with the advantage of automatically preventing and clearing blockages in the hopper. To a certain extent, it improves and solves the problem that in the operation of existing biomass pellet burners, the biomass pellets in the hopper have poor mobility and are prone to accumulation at the bottom of the hopper due to their own gravity, resulting in poor pellet flow to the feed pipe and even the phenomenon of the upper pellets remaining stationary while the lower part has an empty layer, which affects the timely supply of fuel.

[0005] This utility model is implemented as follows: a fully combusting biomass heating device includes a furnace, a control box, a feed pipe, a screw conveyor, and a hopper. The control box is located on the right side of the furnace and is fixedly connected to the furnace. The feed pipe is fixedly connected to the upper right side of the furnace and communicates with the furnace. The screw conveyor is located inside the feed pipe. The hopper is fixedly connected to the upper right side of the feed pipe and communicates with the feed pipe. An anti-blocking device is provided inside the hopper, which includes a tilting component, a vibration component, and a linkage component.

[0006] The preferred embodiment of this invention features a tumbling assembly located at the lower end of the hopper. Two vibration assemblies are positioned on the left and right sides of the hopper, respectively. Four linkage components are positioned on the front and rear sides of the two vibration assemblies. An anti-blocking device is used to improve particle mobility, preventing particle accumulation at the lower end of the hopper and hindering their descent into the feed pipe, thus affecting the supply to the machine body. This effectively ensures stable particle descent into the feed pipe, thereby ensuring sufficient fuel supply in the furnace and laying the foundation for complete biomass combustion.

[0007] The preferred flipping assembly of this utility model includes a rotating rod, a flapping plate, a pressing wheel, and a motor. The rotating rod is disposed at the lower end of the hopper, with its front and rear ends extending out of the hopper and rotatably connected to it. Several flapping plates are evenly and fixedly connected to the circumference of the rotating rod. Two pressing wheels are respectively fitted onto the front and rear ends of the rotating rod and fixedly connected to it. The motor is fixedly connected to the front end of the rotating rod and to the front side of the hopper. By setting the flipping assembly at the lower end of the hopper, the material is flipped, improving its mobility and preventing accumulation and blockage at the lower end of the hopper, thus preventing and clearing blockages.

[0008] The preferred vibration assembly of this utility model includes a rotating seat, a rotating impact plate, and tension springs. The rotating seat is fixedly connected to the upper end of the left surface of the hopper. The upper end of the rotating impact plate is sleeved on the surface of the rotating seat and rotatably connected to the rotating seat. There are two tension springs, which are respectively fixedly connected to the front and rear sides of the upper end of the right surface of the rotating impact plate. The right ends of the two tension springs are fixedly connected to the left surface of the hopper. The linkage is arranged on the front and rear sides of the rotating impact plate and corresponds to the two extrusion rollers. By setting two vibration assemblies, the rotating impact plate is used to act on the left and right sides of the hopper. The instantaneous vibration generated by the slapping can further improve the downward movement of the particles and prevent the particles from accumulating in the hopper and not falling, which would cause the particles to remain stationary at the top of the hopper and create an empty layer at the bottom. It works in conjunction with the turning assembly to play a role in preventing blockage and clearing the hopper.

[0009] As a preferred embodiment of this invention, the right surface of the rotating impact plate is uniformly provided with a plurality of rubber protrusions, which are fixedly connected to the rotating impact plate. By uniformly providing a plurality of rubber protrusions on the right surface of the rotating impact plate, the hopper is directly contacted and struck, which avoids damage to the hopper when the rotating impact plate strikes, and at the same time reduces the noise generated by the striking.

[0010] The preferred linkage component of this utility model includes a connecting rod and a pressure plate. The connecting rod is fixedly connected to the lower end of the front surface of the rotating impact plate, and the pressure plate is fixedly connected to the right end of the front side of the connecting rod. The positions of the pressure plate and the extrusion wheel correspond to and are adapted to each other. By setting the linkage component, the pressure plate and the extrusion wheel are pressed together to drive the rotating impact plate to rotate and strike. This achieves the effect of linking the two vibration components through the rotation of the flipping component, so as to achieve the simultaneous flipping and striking.

[0011] In this invention, the right side of the rubber protrusion is pressed into contact with the surface of the hopper. By setting the right side of the rubber protrusion to press into contact with the surface of the hopper, the rubber protrusion can effectively contact the hopper during impact, producing a better impact effect and enhancing the vibration transmission efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated use of a combustion furnace, control box, feed pipe, screw conveyor, hopper, anti-blocking device, tilting assembly, rotating rod, tilting plate, extrusion wheel, motor, vibration assembly, rotating seat, rotating impact plate, tension spring, linkage component, connecting rod, pressure plate, and rubber protrusion, improves to a certain extent the problem of poor biomass pellet mobility in the hopper during the operation of existing biomass pellet burners. The pellets are easily compacted and piled up at the bottom of the hopper due to their own gravity, resulting in poor pellet flow to the feed pipe and even the phenomenon of the upper pellets remaining stationary while the lower layer of empty space appears, affecting the timely supply of fuel.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown in the figure, the present invention provides a fully combusted biomass heating device, including a furnace 1, a control box 2, a feed pipe 3, a screw conveyor 4, and a hopper 5. The control box 2 is located on the right side of the furnace 1 and is fixedly connected to the furnace 1. The feed pipe 3 is fixedly connected to the upper right side of the furnace 1 and communicates with the furnace 1. The screw conveyor 4 is located inside the feed pipe 3. The hopper 5 is fixedly connected to the upper right side of the feed pipe 3 and communicates with the feed pipe 3. An anti-blocking device 6 is provided inside the hopper 5. The anti-blocking device 6 includes a flipping component 61, a vibration component 62, and a linkage component 63.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The tumbling component 61 is located at the lower end of the hopper 5. There are two vibration components 62, which are located on the left and right sides of the hopper 5 respectively. There are four linkage components 63, which are located on the front and rear sides of the two vibration components 62 respectively.

[0024] The above solution involves setting up an anti-blocking device 6 to improve pellet mobility and prevent poorly moving pellets from accumulating at the bottom of the hopper 5, which would hinder their descent into the feed pipe 3 and affect the supply to the machine body. This effectively ensures that the pellets fall stably into the feed pipe 3, thereby ensuring sufficient fuel supply in the furnace 1 and laying the foundation for the complete combustion of biomass.

[0025] refer to Figure 2 , Figure 3 and Figure 4The flipping assembly 61 includes a rotating rod 611, a flap 612, an extrusion wheel 613, and a motor 614. The rotating rod 611 is located at the lower end of the inside of the hopper 5. The front and rear ends of the rotating rod 611 extend out of the hopper 5 and are rotatably connected to the hopper 5. There are several flaps 612, which are evenly and fixedly connected to the circumference of the rotating rod 611. There are two extrusion wheels 613, which are respectively sleeved on the front and rear ends of the rotating rod 611 and fixedly connected to the rotating rod 611. The motor 614 is fixedly connected to the front end of the rotating rod 611 and fixedly connected to the front side of the hopper 5.

[0026] The above solution is adopted: by setting a turning component 61 at the lower end of the hopper 5, the material is turned over. The turning over improves the mobility of the material, thereby avoiding the accumulation and blockage at the lower end of the hopper 5, and playing the role of preventing and clearing blockage.

[0027] refer to Figure 1 , Figure 3 and Figure 5 The vibration assembly 62 includes a rotating seat 621, a rotating impact plate 622, and a tension spring 623. The rotating seat 621 is fixedly connected to the upper left surface of the hopper 5. The upper end of the rotating impact plate 622 is sleeved on the surface of the rotating seat 621 and rotatably connected to the rotating seat 621. There are two tension springs 623, which are fixedly connected to the front and rear sides of the upper right surface of the rotating impact plate 622 respectively. The right ends of the two tension springs 623 are fixedly connected to the left surface of the hopper 5. The linkage 63 is arranged on the front and rear sides of the rotating impact plate 622 and corresponds to the two extrusion rollers 613.

[0028] The above solution is adopted: by setting two vibration components 62, the left and right sides of the hopper 5 are used to rotate the impact plate 622. The instantaneous vibration generated by the slapping can further improve the mobility of the particles falling downward, and prevent the particles from accumulating in the hopper 5 and not falling, which would cause the particles to remain stationary at the top of the hopper 5 and create an empty layer at the bottom. In conjunction with the turning component 61, it plays a role in preventing blockage and clearing.

[0029] refer to Figure 3 and Figure 5 Several rubber protrusions 7 are evenly arranged on the right surface of the rotating impact plate 622, and the rubber protrusions 7 are fixedly connected to the rotating impact plate 622.

[0030] The above solution involves uniformly arranging several rubber protrusions 7 on the right surface of the rotating impact plate 622 to directly contact and strike the hopper 5. This avoids damage to the hopper 5 when the rotating impact plate 622 strikes, while also reducing the noise generated by the striking.

[0031] refer to Figure 3 and Figure 5The linkage 63 includes a connecting rod 631 and a pressure plate 632. The connecting rod 631 is fixedly connected to the lower end of the front surface of the rotating impact plate 622, and the pressure plate 632 is fixedly connected to the right end of the front side of the connecting rod 631. The positions of the pressure plate 632 and the extrusion wheel 613 correspond to and are adapted to each other.

[0032] The above solution is adopted: by setting up a linkage component 63, the pressure plate 632 and the extrusion wheel 631 are used to push the rotating impact plate 622 to rotate and strike, so as to link the two vibration components 62 through the rotation of the flipping component 61, and realize the flipping and striking at the same time.

[0033] refer to Figure 3 and Figure 5 The right side of the rubber protrusion 7 is pressed into contact with the surface of the hopper 5.

[0034] The above solution involves setting the right side of the rubber protrusion 7 to make contact with the surface of the hopper 5, so that the rubber protrusion 7 can effectively contact the hopper 5 during impact, resulting in a better impact effect and enhancing the vibration transmission efficiency.

[0035] The working principle of this utility model:

[0036] In operation, the control motor 614 drives the rotating rod 611 to rotate. The rotating rod 611 drives the circumferentially distributed flaps 612 to agitate the biomass pellets at the lower end of the hopper 5, preventing pellet accumulation. Simultaneously, the extrusion rollers 613 at both ends of the rotating rod 611 rotate synchronously with the rotating rod 611. When the extrusion rollers 613 rotate to contact the pressure plate 632 of the linkage 63, the pressure plate 632 is compressed, which pushes the rotating impact plate 622 to rotate via the connecting rod 631. The rotating impact plate 622 rotates upward around the rotating seat 621. At this time, the rotating impact plate 622 rotates to the right. The rubber protrusion 7 on the side separates from the surface of the hopper 5, and at the same time the tension spring 623 is stretched and stored. When the extrusion wheel 613 disengages from the pressure plate 632, the tension spring 623 instantly resets and releases its elasticity, driving the rotating impact plate 622 to quickly strike the side wall of the hopper 5. The rubber protrusion 7 and the surface of the hopper 5 are pressed into contact, transmitting high-frequency vibration to the inside of the hopper 5. Through the stirring of the tumbling component 61 and the periodic striking of the vibration component 62, a synergistic anti-blocking effect is formed. The particles falling into the inside of the feed hopper 5 tube are conveyed into the combustion furnace 1 by the screw conveyor 4 for combustion.

[0037] In summary, this fully combusted biomass heating device, through the coordinated use of a combustion furnace 1, control box 2, feed pipe 3, screw conveyor 4, hopper 5, anti-blocking device 6, tilting assembly 61, rotating rod 611, tilting plate 612, extrusion wheel 613, motor 614, vibration assembly 62, rotating seat 621, rotating impact plate 622, tension spring 623, linkage 63, connecting rod 631, pressure plate 632, and rubber protrusion 7, improves to a certain extent the problem of poor biomass pellet mobility in the hopper during the operation of existing biomass pellet burners. The pellets are easily compacted and piled up at the bottom of the hopper due to their own gravity, leading to poor descent of the pellets into the feed pipe and even the phenomenon of the upper pellets remaining stationary while the lower layer of empty space appears, affecting the timely supply of fuel.

[0038] It should be noted that the screw conveyor 4 and the motor 614 are existing devices or equipment, or devices or equipment that can be implemented with existing technology, and the specific composition and principle of the power supply of the screw conveyor 4 and the motor 614 are clear to those skilled in the art, so they will not be described in detail here.
