[0028] Example 2

[0029] When the present invention is used, the raw materials enter the feed barrel 22, which is wide at the top and narrow at the bottom, so that the biomass is prevented from being scattered outside. The biomass flows along the feed barrel 22 to the stirring chamber 1 below, and the biomass is stirred by the stirring blades 24 inside the stirring ring 2. The stirring is more delicate and the evaporation of water is maximized. The stirred biomass flows downward along the stirring barrel 3 to the pull-out screen 16 by gravity, and the ash is separated on the pull-out screen 16. The dust removal mechanism provided on the side wall of the drying box blows the dust and ash to the dust storage box 17 on the side wall. The properly stirred biomass passes through the screen holes 32 on the pull-out screen 16 and reaches the tumbling drying machine below by gravity. The drying box 9 and the sensor 23 provided on the side wall of the tumbling drying box 9 sense a certain weight and merge the upper top cover 26, which is tumbled 360 degrees by the motor 8 and the rotating rod 27, so that the biomass is dried on multiple sides under the combination of the heater 19 below and the tumbling drying box 9, so that its moisture is evaporated to the maximum. After drying is completed, the lower bottom cover 29 is opened to move the dried biomass to the lowest conveying slope 11. The biomass slides through the conveying slope 11 into the conveying pipe 12 of the conveying port, and enters the collection box 15 along the collection pipe 14 through the suction of the suction machine 13, and the dried biomass is collected in the collection box 15.

[0030] When the biomass enters the filter chamber, if the ash of the pull-out screen 16 is too fine and gets stuck in the screen hole 32, the pull-out screen 16 is pulled out through the slide 36 using the pull-out opening on the side wall of the drying box to process the stuck biomass. When the processing is completed, it is inserted into the filter chamber again and pushed forward. A magnetic sticker 37 is provided on the side wall of the pull-out screen 16, which is automatically magnetically attracted to the inside for fixation when it approaches the wall.

[0031] When the tumble drying box 9 is working, the gate below the upper mixing barrel 3 is automatically closed. A controller is provided between the two, which will take action when a signal is sensed. When the tumble drying box finishes the previous round of work, the gate opens and transports the next round of biomass to the bottom for further drying, which is more convenient and intelligent.

[0032] The new components added in the utility model make the biomass drying more thorough, and the biomass is tumbled 360 degrees for drying, so that the later combustion rate effect is maximized, which is more convenient and quick and increases work efficiency.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
