[0002] Straw pellets are a type of biomass energy. They are solid fuels made by crushing and compressing discarded crop waste such as straw, wheat straw, and corn straw. They are a type of biomass pellet, and together with wood pellets, fruit shell pellets, etc., they constitute a diversified system of biomass energy.

[0003] After preparation, the straw can be formed into particles of a specific shape, and then the straw is separated and converted into organic fertilizer.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 8 As shown, the present application provides a separation device for processing straw particles, including a conveying mechanism 1; the conveying mechanism 1 includes a conveying plate 11; the side wall of the conveying plate 11 is rotatably connected to a conveying shaft 13; the conveying shaft 13 is sleeved with a conveyor belt 12, and further includes:

[0037] The wind separation chamber 2 is arranged above the conveyor belt 12 and is used for separating straw particles;

[0038] A separation mechanism 3, arranged below the conveyor belt 12, is used for secondary separation of straw particles;

[0039] The flow guiding mechanism 4 is arranged above the separation mechanism 3 and is used for guiding and discharging the straw particles;

[0040] The pushing mechanism 5 is arranged in the separation mechanism 3 and is used for discharging the straw particles;

[0041] A shaking mechanism 6, connected to the separation mechanism 3, and used to drive the separation mechanism 3 to shake;

[0042] During operation, in the prior art, during the preparation of straw pellets, a portion of straw leaves may be transported to the screening machine together with the pellets. Then, during separation, the straw leaves in the straw pellets may clog the screen. Moreover, the straw leaves are light in weight, and it may not be possible to separate the straw leaves from the screen by simple vibration, resulting in reduced separation efficiency. In order to prevent such incidents from happening, first, the processed straw pellets are transported to the conveyor belt 12 in the conveying mechanism 1, and then the conveyor belt 12 is started to transport the straw pellets to the separation mechanism 3. When the straw pellets arrive at the separation mechanism 3, the straw pellets are Before leaving the mechanism 3, the straw particles will reach the bottom of the air separation bin 2. Since the straw leaves will be discharged together with the straw particles after processing, and the straw leaves are relatively light, the straw leaves can be sucked away by the air separation bin 2, thereby realizing the initial separation of the straw particles. The straw particles separated by the air separation bin 2 are conveyed to the separation mechanism 3 by the conveyor belt 12, and are subjected to secondary separation by the separation mechanism 3. Finally, they are sent out of the separation bin 31 by the pushing mechanism 5 to complete the operation. While the separation mechanism 3 is working, the separation mechanism 3 is continuously driven to shake by the shaking mechanism 6, which can speed up the progress of the separation operation.

After squeezing, the vibration spring 351 rebounds, which will drive the separation plate 37 to shake, thereby driving the straw particles to be lifted from the separation plate 37 for a distance. Through this shaking, the impurities remaining in the straw particles can be quickly separated and filtered. At the same time, the separation plate 37 below is driven The impact column 33 rotates, and when the impact column 33 rotates, the separation plate 37 is continuously impacted by the impact rod 331.

During separation, the pushing screw 52 in the pushing bin 51 is also driven to rotate. During rotation, the pushing plate 54 is used to push the straw particles on the separation plate 37 to the discharge port 311 for discharge. Through the coordinated arrangement of the impact column 33 and the vibration spring 351, the straw particles can be separated for a second time, and the separation efficiency is also accelerated.

During rotation, the pushing plate 54 will be used to push the straw particles on the separation plate 37 to the discharge port 311 for discharge.
