Description

Technical Field

[0001] The utility model relates to the technical field of biomass heaters, in particular to a biomass heater capable of preventing biomass particles from sticking. Background Art

[0002] Biomass pellets are made by cold-dense molding of crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. By processing the biomass raw materials into biomass pellets, the biomass can be burned more fully and the residue during combustion can be reduced.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN220453716U discloses a biomass particle burning heater, including: a shell assembly, the interior of which is divided into a first combustion chamber and a second combustion chamber that are interconnected, a feed port and a first air inlet that are connected to the first combustion chamber; a combustion pipe, arranged in a vertical direction, with the upper end extending upward from the shell assembly, and the lower end extending into the second combustion chamber, and the side is provided with an inlet that is connected to the second combustion chamber, and the lower end of the combustion pipe is provided with an air inlet channel that gradually narrows from top to bottom, and the air inlet channel is connected to the first air inlet. The biomass particles burn in the first combustion chamber to produce a large amount of smoke and open flames, and the smoke enters the combustion pipe through the inlet. The air inlet channel can accelerate the air in the second combustion chamber to be sucked into the combustion pipe. In a high temperature environment, the air mixed with the smoke is further burned in the combustion pipe, so that the biomass particles are fully burned, the energy utilization efficiency is improved, and the pollution to the ambient air is reduced.

[0004] The above mechanism performs secondary combustion of air and flue gas to make biomass particles burn fully and reduce the impact on the environment. However, in actual use, the biomass particles may stick together due to improper storage. When burning, the sticky particles will cause incomplete combustion, affecting the overall combustion efficiency, and also causing excessive residues. In addition, the sticky particles will cause blockage of the feed port when feeding. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a biomass heater for preventing biomass particles from sticking, comprising a heater body and a fan arranged on one side of the heater body, one side of the fan is connected to an air inlet pipe through a pipeline, the air inlet pipe is arranged on one side of the interior of the heater body, and the other side of the interior of the heater body is fixedly connected to a combustion box, a plurality of mixing tubes are fixedly connected to the top of the combustion box, and one side of the mixing tube is connected to the air inlet pipe through a pipeline, a dust collection box is fixedly connected to the bottom end of the interior of the heater body below the combustion box, a feed box is fixedly connected to the other side of the heater body, and a feed port is provided on one side of the top of the feed box, a heat dissipation port is provided at one end of the heater body, and heat dissipation fins are fixedly connected to the upper and lower ends of one end of the heater body;

[0007] The top of the feed box is fixedly connected to a first drive motor, and the output end of the first drive motor is provided with an anti-adhesion mechanism to prevent the biomass particles from sticking and causing blockage, the anti-adhesion mechanism comprises a rotating rod, and the rotating rod is fixed at a distance from the output end of the first drive motor, and the top and bottom ends of both sides of the rotating rod are fixedly connected to connecting rods;

[0008] One end of the feed port is slidably connected with a toggle plate, and one end of the toggle plate is provided with an anti-blocking mechanism for preventing the feed port from being blocked and adhered by biomass particles.

[0009] Furthermore, a mounting rod is fixedly connected to one end of the connecting rods, and a plurality of moving brushes are fixedly connected to the outer side of the mounting rod, and the moving brushes are evenly spaced and distributed on the outer side of the mounting rod.

[0010] Furthermore, the anti-blocking mechanism includes a cam, and the cam is rotatably connected to the top of the feed box, the output end of the first drive motor is wound around the lower end of the outer side of the cam through a pulley mechanism, and the cam is arranged at one end of the feed port.

[0011] Furthermore, one end of the toggle plate is fixedly connected to a push plate, and one end of the push plate passes through and extends to the outside of the feed port.

[0012] Furthermore, both sides of one end of the push plate are fixedly connected with a return spring, and an elastic structure is formed between one end of the return spring and the feed port.

[0013] Furthermore, a feed pipe is fixedly connected to the bottom of the feed box, and a second drive motor is fixedly connected to one side of the feed pipe. The output end of the second drive motor extends to the inside of the feed pipe and is fixedly connected to a spiral feeding rod.

[0014] Furthermore, the spiral feeding rod is arranged directly below the feed box, and one side of the spiral feeding rod passes through and extends to the interior of the combustion box.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The output end of the first driving motor drives the rotating rod to rotate, and at the same time, the rotating rod can drive the mounting rods and the toggle brushes on both sides to continuously rotate inside the feed box, so that the adhering biomass particles are continuously toggled by the toggle brushes to separate the adhering biomass particles, and at the same time, it also prevents the blockage of the drop port caused by too many biomass particles falling at one time;

[0017] Furthermore, the fan blows air into the mixing tube through the air inlet pipe, so that the inside of the mixing tube is full of oxygen, and the biomass particles can be burned more fully. At the same time, the flue gas and air are mixed and rise inside the mixing tube. Since the inside of the heater body and the mixing tube are both in a high temperature environment, the flue gas and air will be secondary burned at the upper end of the mixing tube, and can burn more fully, reducing the residual biomass particles.

[0018] Furthermore, the number of biomass particles falling from the feeding port into the combustion chamber each time can be limited by the spiral feeding rod, and the number of biomass particles falling into the combustion chamber can be controlled differently by the different rotation speeds of the spiral feeding rod, thereby adjusting the degree of combustion and the temperature. Furthermore, the continuous rotation of the spiral feeding rod can gradually transport the particles to the combustion chamber for combustion, thereby avoiding the situation in which the feed port on one side of the combustion chamber is blocked and the subsequent combustion cannot be caused.

[0019] 2. The first driving motor can drive the cam to rotate through the pulley during the rotation process, so that the cam continuously moves the propulsion plate, so that the propulsion plate moves to one side. The reset spring is shortened due to the force after the propulsion plate is squeezed, and the propulsion plate repeatedly pulls the toggle plate inside the feed port, so that the biomass particles fed from the feed port will not cause the feed port to be blocked due to adhesion, thereby ensuring the stable feeding of the biomass particles, so that the overall combustion efficiency of the heater body can also be guaranteed;

[0020] Furthermore, the elastic force of the reset spring will automatically reset the push plate after the cam rotates to the other side, so that the biomass particles are repeatedly moved when feeding at the feed inlet, thereby effectively reducing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 5 The technical solution shown is to solve the problem of incomplete combustion caused by adhesion of biomass particles during use: the biomass heater for preventing biomass particles from sticking discloses an anti-adhesion mechanism, including a heater body 1 and a fan 2 arranged on one side of the heater body 1, one side of the fan 2 is connected to an air inlet pipe 3 through a pipeline, the air inlet pipe 3 is arranged on one side of the heater body 1, and a combustion box 5 is fixedly connected to the other side of the heater body 1, a plurality of mixing tubes 4 are fixedly connected to the top of the combustion box 5, and one side of the mixing tube 4 is connected to the air inlet pipe 3 through a pipeline, a dust collection box 6 is fixedly connected to the bottom end of the heater body 1 below the combustion box 5, a feed box 9 is fixedly connected to the other side of the heater body 1, and a feed port 10 is provided on one side of the top of the feed box 9, a heat dissipation port 21 is provided at one end of the heater body 1, and heat dissipation fins 20 are fixedly connected to the upper and lower ends of one end of the heater body 1;

[0032] The top of the feed box 9 is fixedly connected to the first drive motor 11, and the output end of the first drive motor 11 is provided with an anti-adhesion mechanism to prevent the biomass particles from sticking and causing blockage. The anti-adhesion mechanism includes a rotating rod 12, and the rotating rod 12 is fixed at a distance from the output end of the first drive motor 11, and the top and bottom ends on both sides of the outside of the rotating rod 12 are fixedly connected with connecting rods 13.

[0033] One end of the connecting rod 13 is fixedly connected to a mounting rod 14 , and the outer side of the mounting rod 14 is fixedly connected to a plurality of moving brushes 15 , which are evenly spaced and distributed on the outer side of the mounting rod 14 .

[0034] In this example, biomass particles are added to the interior of the feed box 9 through the feed port 10, and the biomass particles enter the interior of the feed pipe 7 through the drop port. The second drive motor 22 rotates to drive the spiral feed rod 8 to transport the biomass particles, so that the biomass particles fall into the interior of the combustion box 5 and burn. During the combustion process, the generated dust will fall from the hole groove opened at the bottom of the combustion box 5 to the interior of the dust collection box 6. At the same time, the fan 2 blows air into the interior of the mixing tube 4 through the air inlet pipe 3, so that the interior of the mixing tube 4 has sufficient oxygen, which can more fully burn the biomass particles. At the same time, the smoke mixes with the air and rises inside the mixing tube 4. Due to the interior of the heater body 1 and the mixing tube 4 When both are in a high-temperature environment, the flue gas and air will undergo secondary combustion at the upper end of the mixing tube 4, and the combustion will be more complete, reducing the residual biomass particles. The heat discharge from the heater body 1 can be achieved through the cooperation between the heat dissipation port 21 and the heat dissipation fins 20, thereby achieving the purpose of heating. The output end of the first drive motor 11 drives the rotating rod 12 to rotate, and at the same time, the rotating rod 12 can drive the mounting rods 14 and the moving brushes 15 on both sides to continuously rotate inside the feed box 9, so that the adhered biomass particles are continuously moved by the moving brush 15, and the adhered biomass particles are separated, while also preventing too many biomass particles from falling at one time and causing blockage in the feed port.

[0035] Embodiment 2:

[0036] like Figure 1 and Figure 5 The technical solution shown is to solve the problem of clogging of particles during transportation: the biomass heater that prevents biomass particles from sticking discloses a feeding mechanism, a feeding pipe 7 is fixedly connected to the bottom of the feeding box 9, and a second drive motor 22 is fixedly connected to one side of the feeding pipe 7, the output end of the second drive motor 22 extends to the inside of the feeding pipe 7 and is fixedly connected to a spiral feeding rod 8, the spiral feeding rod 8 is arranged directly below the feeding box 9, and one side of the spiral feeding rod 8 passes through and extends to the inside of the combustion box 5.

[0037] In this example, the spiral feeding rod 8 can limit the number of biomass particles falling into the interior from the drop-out port each time, and the different rotation speeds of the spiral feeding rod 8 can control the number of biomass particles falling into the interior differently, thereby achieving adjustment of the degree of combustion and temperature, and the continuous rotation of the spiral feeding rod 8 can gradually transport the particles to the interior of the combustion box 5 for combustion, thereby avoiding blockage at the feed point on one side of the combustion box 5 and causing subsequent combustion failure.

[0038] Embodiment three:

[0039] like Figure 1 , Figure 6 and Figure 7 The technical solution shown is to solve the problem of the feed port being blocked and obstructed due to the adhesion of biomass particles during the feeding process: the biomass heater that prevents the biomass particles from sticking discloses an anti-blocking mechanism, one end of the feed port 10 is slidably connected to a toggle plate 19, and one end of the toggle plate 19 is provided with an anti-blocking mechanism for preventing the feed port 10 from being blocked and adhered by biomass particles.

[0040] The anti-blocking mechanism includes a cam 16, and the cam 16 is rotatably connected to the top of the feed box 9, the output end of the first drive motor 11 is wound around the lower end of the outer side of the cam 16 through a pulley mechanism, and the cam 16 is arranged at one end of the feed port 10.

[0041] One end of the toggle plate 19 is fixedly connected to the push plate 17, and one end of the push plate 17 passes through and extends to the outside of the feed port 10. Both sides of one end of the push plate 17 are fixedly connected to the return spring 18, and an elastic structure is formed between one end of the return spring 18 and the feed port 10.

[0042] In this example, the first drive motor 11 can drive the cam 16 to rotate through the pulley during the rotation process, so that the cam 16 continuously pushes the push plate 17, causing the push plate 17 to move to one side. The return spring 18 is shortened due to the force after the push plate 17 is squeezed, and the push plate 17 repeatedly pulls the push plate 19 inside the feed port 10, so that the biomass particles fed from the feed port 10 will not cause the feed port 10 to be blocked due to adhesion, thereby ensuring the stable feeding of the biomass particles, so that the overall combustion efficiency of the heater body 1 can also be guaranteed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
