DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 3 As shown, a biomass combustible waste pelletizing device includes a bracket 1, a crushing box 2 is provided above the bracket 1, the crushing box 2 is provided with a feed port 3 and a discharge port 4, the crushing teeth 15 in the crushing box 2 can quickly crush the input biomass fuel raw materials into small particles, a screen 13 is provided at the discharge port 4, and is connected to a mixing box 5, the evenly crushed biomass raw materials enter the mixing box 5, and as the agitator 14 rotates, the adhesive sprayer 6 will evenly spray the adhesive on the small particles of the biomass raw materials, the bottom of the mixing box 5 is connected to the extrusion box 7, the extrusion box 7 is provided with a spiral shaft extruder 12, the tail end of the extrusion box 7 is provided with a forming die hole 8, the outside of the forming die hole 8 is provided with a cutting knife 9, the cutting knife 9 is driven by an electric motor and controlled by a PLC control module, and adopts an intermittent cutting working mode.

[0019] Preferably, a pair of rollers 11 are provided at the bottom of the mixing box 5 , and the rollers 11 are driven by an electric motor to perform preliminary compaction on the mixed biomass raw materials, so that the subsequent extrusion work in the extrusion box 7 is more efficient.

[0020] The usage process of the present invention is as follows: the operator first starts the entire device, and the electromagnetic adsorption device 10, the adhesive sprayer 6 and each motor start to operate, and then the biomass raw material is put into the feed port 3. After the raw material is crushed, it passes through the screen 13 and enters the mixing box 5. After being sprayed with adhesive and stirred, it falls onto the roller 11. The roller 11 rotates and crushes the raw material mixture and then sends it into the extrusion box 7 below. The motor drives the extruder 12 in the extrusion box 7 to rotate, and the raw material mixture is squeezed toward the tail end of the extrusion box 7, and finally comes out through the forming die hole 8. The working frequency of the cutting knife 9 is manually set to control the particle length and size.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to modification and variation. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
