[0002] Biomass pellets are a renewable energy product, typically made from compressed organic materials. These materials can include wood waste (such as sawdust, branches, and bark), crop residues (such as corn stalks or rice husks), and other organic waste. In order to ensure that the various materials in the biomass pellets are evenly distributed, they need to be stirred and mixed during the processing process.

The biomass pellet raw material mixing device, through the arrangement of the first motor and the mixing device, when mixing raw materials, adds raw materials from the feed hopper to the mixing trough, starts the first motor, drives the mixing device to stir and mix the raw materials, and has high mixing efficiency. Through the arrangement of the first chute, slider, spring, second motor and bent shaft, the second motor is started to drive the bent shaft to rotate. Under the action of the first chute and slider, the mixing trough moves vertically up and down, so that the raw materials are mixed more evenly and the mixing efficiency is improved.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-Figure 5A raw material mixing and stirring device for biomass pellet processing comprises an outer cylinder 1 with supporting legs, the inner wall of the bottom surface of the outer cylinder 1 is rotatably connected to a discharge pipe 3, the upper end of the discharge pipe 3 is fixedly connected to an inner cylinder 11, the upper end of the inner cylinder 11 is rotatably connected to a feed hopper 2, the outer wall of the upper end of the outer cylinder 1 is connected to a power mechanism, the output end of the power mechanism is connected to a transmission assembly, the other end of the transmission assembly is connected to one end of the feed hopper 2 located outside the outer cylinder 1, the outer wall of one end of the feed hopper 2 located inside the outer cylinder 1 is connected to a reverse assembly and a conveying assembly, one end of the reverse assembly is connected to the upper end of the inner cylinder 11, and the conveying assembly is located inside the inner cylinder 11.

[0025] like Figures 1 to 5 As shown, when the raw material mixing and stirring device for biomass particle processing in the utility model is used, the discharge pipe 3 is first closed, and then the biomass particle raw material to be mixed and stirred (hereinafter referred to as raw material) is put into the feed hopper 2. The raw material after being put into the feed hopper 2 enters the inner cylinder 11, and then the power mechanism is turned on through the external controller (this is the existing technology, so it is not described in detail). After the power mechanism is started, the feed hopper 2 is driven to rotate through the transmission component. The rotation of the feed hopper 2 can drive the reversing component and the conveying component to rotate, and the rotation directions of the reversing component and the conveying component are opposite, so that the raw material inside the inner cylinder 11 can be continuously raised, freely fallen, and stirred, thereby accelerating the mixing speed and improving the mixing efficiency.

[0026] like Figure 1-Figure 3 As shown, the power mechanism includes a motor frame 4 and a rotating motor 5. One end of the motor frame 4 is fixedly connected to the upper surface of the outer wall of the outer cylinder 1, and the other end of the motor frame 4 is fixedly connected to the outer wall of the rotating motor 5. The output shaft of the rotating motor 5 is connected to the transmission assembly.

[0027] More specifically, when the inner drum 11 needs to be controlled to rotate, the rotating motor 5 only needs to be turned on through an external controller, and the output shaft of the rotating motor 5 can drive the transmission assembly to rotate.

[0028] like Figure 1-Figure 3 As shown, the transmission assembly includes a No. 1 gear 6 and a No. 2 gear 7. The inner wall of the No. 1 gear 6 is fixedly connected to the output shaft of the rotating motor 5. The No. 2 gear 7 is sleeved and fixedly connected to the outer wall of the upper end of the feed hopper 2. The No. 1 gear 6 and the No. 2 gear 7 are meshed.

[0029] More specifically, when the rotating motor 5 is started, the output shaft can drive the No. 1 gear 6 to rotate. After the No. 1 gear 6 rotates, it will engage and drive the No. 2 gear 7 to rotate, thereby driving the feed hopper 2 located inside the No. 2 gear 7 and the reverse component and conveying component located at the lower end of the feed hopper 2 to rotate together.

[0030] like Figure 2-Figure 5As shown, the reverse assembly includes a number three gear 8, an inner gear ring 10 and a number of number four gears 9. The number three gear 8 is sleeved and fixedly connected to the outer wall of the lower end of the feed hopper 2. The bottom surface of the inner gear ring 10 is fixedly connected to the upper surface of the outer wall of the inner cylinder 11. The upper ends of the number four gears 9 are rotatably connected to the upper surface of the inner wall of the outer cylinder 1. The number three gear 8 is meshed with the number four gears 9, and the other ends of the number four gears 9 are meshed with the inner gear ring 10.

[0031] More specifically, when the feed hopper 2 rotates, it will drive the third gear 8 connected to its surface to rotate. After the third gear 8 rotates, it can drive several fourth gears 9 to rotate in the opposite direction. After the fourth gears 9 rotate, they can drive the external inner gear ring 10 to rotate in the same direction. Because the rotation direction of the inner gear ring 10 is opposite to that of the feed hopper 2, the rotation direction of the inner cylinder 11 and the conveying assembly can be made opposite.

[0032] like Figure 4 and Figure 5 As shown, the conveying assembly includes a U-shaped frame 12 and a spiral disk 13. Both ends of the U-shaped frame 12 are fixedly connected to the bottom surface of the feed hopper 2, and the bottom surface of the U-shaped frame 12 is fixedly connected to the upper end of the central axis of the spiral disk 13. The U-shaped frame 12 and the spiral disk 13 are both located inside the inner cylinder 11.

[0033] More specifically, when the feed hopper 2 rotates, the spiral disk 13 will rotate together under the action of the U-shaped frame 12, and then, through its own characteristics, the raw materials at the bottom of the inner cylinder 11 can be transported to the outside of the inner cylinder 11. After that, these raw materials will freely fall to the bottom of the inner cylinder 11 to achieve circulation, so that the mixing of the raw materials can be completed more quickly.

[0034] like Figure 4 and Figure 5 As shown, a plurality of equally spaced baffles 14 are fixedly connected to the inner wall of the spiral disk 13 .

[0035] More specifically, by providing the baffle 14, the stability of the raw material on the spiral disk 13 can be increased, making it less likely to slide and not rise.

[0036] like Figure 4 and Figure 5 As shown, the bottom surface of the inner wall of the inner cylinder 11 is fixedly connected with an inclined cover 15 , which is sleeved on the outside of the spiral disk 13 , and the inner wall of the inclined cover 15 does not contact the spiral disk 13 .

[0037] More specifically, by providing the inclined cover 15 , it is possible to avoid the situation where the raw materials at the lower end of the inner cylinder 11 are accumulated on the side wall of the inner cylinder 11 and cannot move along with the spiral disk 13 for mixing.

[0038] like Figure 4 and Figure 5 As shown, a scraper 16 is fixedly connected to the inner wall of the inclined cover 15 , and the upper end of the scraper 16 protrudes from the upper end of the inclined cover 15 .

[0039] More specifically, by providing the scraper 16 , the impact on the raw materials inside the inner drum 11 can be increased when the inner drum 11 rotates, thereby enhancing the stirring and mixing effect.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
