Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel processing, in particular to a mixer for biomass fuel processing. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, which are generally agricultural and forestry wastes such as straw, sawdust, bagasse, wood materials, etc. The processing of biomass fuel requires crushing, mixing, extrusion, drying and other processes to make various shapes (such as blocks, granules, etc.), so a mixing device is required.

[0003] The existing equipment for mixing biomass fuel raw materials is mainly mixers of various models. However, we have found in actual use that the stirring structure of the mixer can only rotate continuously in the same direction. This mixing method will cause the raw materials of the biomass fuel to always rotate in one direction, resulting in poor mixing effect of the raw materials at the edge. At the same time, there is moisture inside the material, which is easy to stick together and cannot be dispersed, making the overall material unable to achieve good uniformity. Therefore, the utility model designs a biomass fuel processing mixer that improves mixing uniformity and avoids agglomeration to solve this existing technical defect. Utility Model Content

[0030] In the embodiment, the mixing machine cylinder 1 is provided with a feeding and distribution assembly.

[0031] It should be noted that the feeding and distribution assembly comprises a circular groove 5 which is communicated between the top inner wall of the mixing machine cylinder 1 and the top opening of the mixing machine cylinder 1, the circular groove 5 is rotationally connected with a disc 6, and the inner wall of the disc 6 is fixedly provided with a feeding hopper 7 which is attached to the mixing machine cylinder 1.

[0032] The bottom wall of the upper hopper 7 is fixedly provided with a boss 8, and the bottom wall of the upper hopper 7 is communicated with a plurality of downwardly inclined distribution pipes 9, facilitating unloading and improving the unloading smoothness.

[0033] The boss 8 is a circular truncated cone body, facilitating the wood chips to fall onto the boss 8 and slide along the inclined surface of the circular truncated cone, and the diameter of the upper hopper 7 is equal to the opening diameter of the top of the mixing cylinder 1.

[0034] The mixing cylinder 1 in the embodiment is provided with a driving mechanism for driving the upper feeding and distribution assembly to rotate and distribute the mixed materials.

[0035] It should be noted that the driving mechanism includes a micro motor 11 fixedly installed on the left side of the mixing cylinder 1 and a transmission disc I 10 fixedly installed on the outside of the upper hopper 7, and a transmission disc II 12 is fixedly installed on the output shaft of the micro motor 11, and a transmission belt 13 is sleeved between the outside of the transmission disc I 10 and the transmission disc II 12.

[0036] The outside of the micro motor 11 is provided with a protective cover with heat dissipation holes.

[0037] The mixing cylinder 1 in the embodiment is provided with a conveying structure for conveying the stirred mixed materials into the upper feeding and distribution assembly for distribution and mixing.

[0038] It should be noted that the conveying structure includes a conveying pipe 14 communicated with the bottom of the mixing cylinder 1, the other end of the conveying pipe 14 is communicated with a conveying cylinder 15, the bottom of the conveying cylinder 15 is fixedly installed with a conveying motor 18, the output shaft of the conveying motor 18 is fixedly installed with a spiral conveying rod 19 rotationally connected with the top wall of the inner cavity of the conveying cylinder 15, and the left top of the conveying cylinder 15 is communicated with a unloading pipe 20 located above the upper hopper 7.

[0039] The outside of the conveying pipe 14 is communicated with a discharge pipe 16 for discharging, and the outside of the discharge pipe 16 is communicated with an on-off control valve 17.

[0042] The working principle of the above embodiment is as follows:

[0043] The micro motor 11 is driven to rotate the transmission disc II 12, and the transmission disc II 12 and the transmission disc I 10 are driven by the transmission belt 13, so that the upper hopper 7 on the transmission disc I 10 is driven to rotate in the circular groove 5 by the circular disc 6 under the transmission of the transmission belt 13.

[0044] Therefore, it is convenient to load the wood chips through the upper hopper 7 when the upper hopper 7 rotates, and the loaded wood chips are distributed to the several circumferentially arranged distribution pipes 9 on the upper hopper 7 through the boss 8 of the frustum. Under the condition of rotation, the loaded wood chips are dispersed and discharged from the various distribution pipes 9 and scattered into the mixing barrel 1, avoiding the traditional direct discharge of the materials into blocks and piles, ensuring the dispersion effect of the materials, and at the same time, the stirring motor 3 is driven by the stirring rod 4 to rotate to mix the dispersed wood chips, thereby improving the uniformity of the stirring and mixing.

[0045] In addition, after a round of mixing and stirring is completed, the stirred material is discharged into the conveying cylinder 15 through the provided conveying pipe 14, and the provided conveying motor 18 works to drive the spiral conveying rod 19 to rotate and spirally convey the stirred wood chips to the discharge pipe 20 and discharge it into the upper hopper 7 for further distribution and stirring, thereby realizing multiple cycles of mixing of the wood chips and improving the uniformity of the mixing.

[0046] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
