[0002] Currently, conventional biomass pellet furnaces consist of a furnace body and a pellet feeder that supplies fuel to the furnace body. The pellet feeder is an integrated structure with the furnace body and is relatively large. The pellet feeder generally includes a box body, a storage bin within the box body, a feed pipe, and a burner. The feed pipe connects the storage bin and the burner at both ends, respectively. The burner extends to a predetermined position in the furnace body for combustion.

[0003] Among them, the feeding pipe is linear to facilitate the smooth supply of biomass pellets. However, this also causes most of the length of the feeding pipe to extend out of the side of the box so that the burner can extend into the furnace body. During the production and assembly process, the part of the feeding pipe extending out of the box is prone to collision and damage. In addition, a large amount of biomass pellets are stored in the pellet feeder, which will further cause the overall center of gravity of the pellet feeder to deviate from the center position, causing difficulties in transportation and carrying, and also causing great inconvenience to the automated production, assembly and transfer processes.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] See also Figures 1 to 3The present invention provides a particle feeder, comprising: a box body 100, wherein the box body 100 has a cavity 110 with a side opening; a storage bin 200, which is arranged inside the box body 100; a feeding pipe 300, one end of which is connected to the output end of the storage bin 200, and the feeding pipe 300 can be displaced relative to the box body 100 to have a working state and a storage state; when the feeding pipe 300 is in the working state, the other end of the feeding pipe 300 extends from the side opening of the cavity 110; when the feeding pipe 300 is in the storage state, the other end of the feeding pipe 300 retracts from the side opening of the cavity 110 to be at least partially accommodated in the cavity 110.

[0031] The particle feeder of the above structure can drive the feeding pipe 300 to switch to a storage state in which it is at least partially contained in the cavity 110 during the production and transportation process, thereby preventing the portion of the feeding pipe 300 extending out of the box body 100 from being easily impacted or damaged, reducing the volume of storage and packaging, and avoiding the impact of the center of gravity deviating significantly from the center position on transportation or carrying. During assembly, the feeding pipe 300 can be driven to switch to a working state extending out of the cavity 110, thereby meeting the installation and use requirements.

[0032] It should be noted that the feed pipe 300 is docked with the output end of the storage bin 200 when in both the operating and storage states, preventing particle leakage when the feed pipe 300 switches positions. When in the storage state, the particle feeder of the conveying device is less likely to tilt when transported by the conveyor belt, facilitating the transfer process in automated production.

[0033] See also Figure 1 and Figure 3 In some embodiments of the present invention, the storage bin 200 is disposed at the upper portion of the housing 100, the feeding pipe 300 is located below the storage bin 200 and is always connected to the storage bin 200, the feeding pipe 300 is in a straight, elongated shape, and the cavity 110 has an elongated storage space below the storage bin 200 that can completely accommodate the feeding pipe 300. It is understood that the particles within the storage bin 200 move downward under their own gravity to enter the feeding pipe 300. The feeding pipe 300 is completely accommodated in the storage space of the cavity 110, that is, it does not protrude from the outer contour of the housing 100, making the overall shape of the particle feeder more regular, which is convenient for storage and stacking as well as arranging in a row for transportation.

[0034] See also Figure 2 and Figure 3In some embodiments of the present invention, a feed screw 310 is rotatably disposed within the feed pipe 300 and extends along its length. One end of the feed screw 310 extends from the end of the feed pipe 300 and is connected to a driver 320 for driving the feed screw 310. A burner 400 is provided on the feed pipe 300 and is connected to the other end of the feed screw 310. It is understood that the driver 320 and the burner 400 are also housed within the cavity 110 along with the feed pipe 300. Particles in the storage bin 200 move downward into one end of the feed pipe 300. As the driver 320 drives the feed screw 310 to rotate, the feed screw 310 propels the particles along the feed pipe 300 toward the burner 400. An ignition rod in the burner 400 continuously transfers heat to the particles through heat conduction, promoting combustion. The feeding screw 310 can accurately control the amount of particles supplied to the burner 400 and prevent the particles from getting stuck. Of course, in other embodiments, the feeding pipe 300 can also be transported by a linear vibrator.

[0035] See also Figure 2 In some embodiments of the present invention, a discharge port 210 is provided at the lower end of the storage bin 200, and a feed port opposite to the discharge port 210 is provided on the top wall of the feed pipe 300 at the end away from the burner 400. The discharge port 210 and the feed port are connected via a rotating tube assembly 500. The feed pipe 300 can rotate about a vertical axis relative to the storage bin 200 to switch between the working state and the storage state. It should be noted that the feed pipe 300 can rotate about the centerline of the rotating tube assembly 500 so that the feed pipe 300 is rotated to be stored in the cavity 110 or rotated to be displayed outside the cavity 110. At the same time, the rotating tube assembly 500 can also maintain a sealed connection between the discharge port 210 of the storage bin 200 and the feed port of the feed pipe 300 to prevent leakage of particulate matter. Of course, in other embodiments, the rotating tube assembly 500 can also be replaced by a corrugated hose.

[0036] See also Figure 5In some embodiments of the present invention, the rotating tube group 500 includes a first inner tube 510 and a first outer tube 520 sleeved on the outside of the first inner tube 510, the central axes of the first inner tube 510 and the first outer tube 520 are coaxial with the vertical axis, one of the first inner tube 510 and the first outer tube 520 is arranged at the discharge port 210, and the other is arranged at the feed port. In this embodiment, a first mounting plate 530 is fixed to the bottom of the storage bin 200 by screws, the first inner circular tube 510 is fixed on the first mounting plate 530, the top of the feeding pipe 300 is fixed to the second mounting plate 540 by screws, the first outer circular tube 520 is fixed on the second mounting plate 540, the first inner circular tube 510 and the first outer circular tube 520 are slidably nested to achieve relative rotation, and the whole formed by the first inner circular tube 510 and the first outer circular tube 520 is used for both particulate matter transmission and for achieving relative rotation between the feeding pipe 300 and the storage bin 200, achieving the effect of one thing serving two purposes.

[0037] See also Figure 5 In some embodiments of the present invention, a rotation support mechanism 600 is provided between the lower side wall of the feeding pipe 300 and the inner bottom wall of the box body 100, and the rotation axis of the rotation support mechanism 600 is coaxial with the vertical axis. It is understandable that when the feeding pipe 300 and the storage bin 200 rely solely on the first inner tube 510 and the first outer tube 520 to achieve relative rotation, the feeding pipe 300 is essentially a cantilever, and the feeding pipe 300 cannot be stably supported, which increases the load on the first inner tube 510 and the first outer tube 520, which may cause abnormal rotation noise and uneven rotation. By adding the rotation support mechanism 600, this problem can be improved or solved. Specifically, in this embodiment, a rectangular frame 900 is further provided on the outside of the feeding pipe 300, and the feeding pipe 300 is installed inside the rectangular frame 900. The rotating support mechanism 600 includes a second inner tube 610 and a second outer tube 620 which is sleeved on the outside of the second inner tube 610. The central axes of the second inner tube 610 and the second outer tube 620 are coaxial with the above-mentioned vertical axis. The second inner tube 610 is provided on the inner bottom wall of the box body 100, and the second outer tube 620 is provided on the lower side wall of the rectangular frame 900. The gap between the second inner tube 610 and the second outer tube 620 is matched to guide the feeding pipe 300 to rotate. Among them, a gas channel 910 is formed between the rectangular frame 900 and the feeding pipe 300, the burner 400 includes a combustion box located in the gas channel 910 and an ignition rod passing through the side wall of the combustion box, and a plurality of air inlet holes 410 are opened on the outer wall of the combustion box. A fan 800 for inputting external gas into the gas channel 910 is provided on the rectangular frame 900, thereby continuously providing oxygen for the combustion of particulate matter.

[0038] See also Figure 3 and Figure 4 In some embodiments of the present invention, the box body 100 is a flat rectangular box. The feeding conduit 300 in the storage state extends along the length of the rectangular box. The storage bin 200 has an upwardly opening input port. A cover 120 is provided at the top of the box body 100 for opening or closing the input port. The cover 120 has a handle 121. It is understood that when adding pellets, the user can grasp the handle 121 to open the input port. After adding pellets, the user locks the cover 120, switching the feeding conduit 300 to the storage state. The pellet feeder thus forms a suitcase shape, making it convenient for the user to carry. Specifically, in this embodiment, one side of the cover 120 along its width is rotatably connected to the box body 100 via a hinge 730, and the other side of the cover 120 along its width is connected to the box body 100 via a snap lock.

[0039] See also Figure 4 In some embodiments of the present invention, in order to protect the feeding pipe 300 housed in the cavity 110 and prevent foreign matter from entering and contaminating the interior of the cavity 110, a switch mechanism 700 is movably provided on the box body 100 for opening or closing the side opening of the cavity 110.

[0040] See also Figure 4 In some embodiments of the present invention, the switch mechanism 700 includes a fixed plate 710 mounted on the side wall of the box body 100 and a baffle 720 rotatably connected to the fixed plate 710 via a hinge 730. The pivot of the hinge 730 is arranged horizontally, and the baffle 720 can be flipped upward to stabilize to open the side opening of the cavity 110, or flipped downward to close the side opening of the cavity 110. The hinge 730 has a certain degree of rotational damping, and the baffle 720 can be stable after flipping upward or downward. When the baffle 720 is flipped upward to open the side opening of the cavity 110, the feeding pipe 300 can be rotated to the working state. When the feeding pipe 300 is rotated to the storage state, the baffle 720 can be flipped downward to close the side opening of the cavity 110.

[0041] The present invention further discloses a combustion device comprising a furnace body and a particle feeder according to any of the above-described technical solutions, mounted on the furnace body. The particle feeder of the combustion device can reduce collisions and damage to the feed pipe 300 during production and transportation, reduce storage volume, and facilitate transportation and portability. During assembly, the feed pipe 300 can be driven to switch to an operating state extending from the cavity 110, thereby meeting installation and operational requirements.

[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

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