[0002] Biomass fuel refers to fuel made from organic matter that has been processed into renewable energy sources that can be directly burned or converted into other forms. Moisture content affects the calorific value and combustion uniformity of the fuel. The specific testing method is similar to that for soil moisture content testing, which involves weighing the fuel before and after drying and calculating the moisture content based on the weight difference.

[0004] However, existing technologies still have shortcomings:

[0005] 1. The above settings require manual removal and installation of the top cover. After reading the initial values, the water suction bucket needs to be manually placed in the tank to dry the material in the tank, which affects the overall detection efficiency of the device.

[0006] 2. When reading the initial value, the water suction bucket was removed, and then the water suction bucket was installed to dry the material in the evaporation shell tank. The water suction bucket was then removed again to read the drying value. When the water suction bucket was removed for the second time, there may be residue on the inner wall due to direct contact with the dried material, which may affect the accuracy of the second reading.

The evaporation tank shell 21 is used to hold the biomass fuel to be dried. The evaporation tank shell 21 is provided with a top cover 23. Specifically, the evaporation tank shell 21 and the top cover 23 are snapped together, which facilitates the installation and removal of the top cover 23 on the evaporation tank shell 21. Several air valves 15 are fixedly provided on the top cover 23. An installation block 12 is rotatably provided on the top cover 23. A rotating shaft 17 is fixedly provided on the installation block 12. The rotating shaft 17 is located inside the evaporation tank shell 21. Several stirring blades 18 are provided at the upper end of the rotating shaft 17 to stir and process the biomass fuel and accelerate its drying and evaporation. Two sets of crushing blades 19 are fixedly provided at the bottom of the rotating shaft 17. The crushing blades 19 are used to crush the biomass fuel.

[0027] In one embodiment, a mounting frame 2 is fixedly mounted on the processing table 1, and a hydraulic cylinder 7 is fixedly mounted on the mounting frame 2. An adjusting frame 8 is fixedly connected to the output shaft of the hydraulic cylinder 7. A motor 10 is fixedly mounted inside the adjusting frame 8, and a threaded block 11 is fixedly connected to the output shaft of the motor 10. The threaded block 11 is fixedly connected to a mounting block 12. Specifically, the mounting block 12 has threaded holes. By screwing the threaded block 11 into the mounting block 12, the threaded block 11 and the mounting block 12 are fixedly connected.

Then, the hydraulic cylinder 7 is started to drive the adjusting frame 8 to descend until the top cover 23 is engaged with the evaporation tank shell 21. Then, the hydraulic cylinder 7 and the motor 10 are started to drive the threaded block 11 to rotate in the reverse direction to disengage the threaded block 11 from the mounting block 12. The electronic balance 3 is started to read the initial value, and then the hydraulic cylinder 7 and the motor 10 are started again to drive the threaded block 11 to rotate in the reverse direction. 1. Rotate forward to fix the threaded block 11 and the mounting block 12. Then start the evaporator shell 5 to heat the evaporator tank shell 21 and dry the fuel in the evaporator tank shell 21. Remove a pair of limit bolts 14 and start the motor 10 to drive the rotating shaft 17 to rotate, thereby cutting and stirring the fuel in the evaporator tank shell 21 and accelerating its drying. After the drying process is completed, reinsert the limit bolts 14. Then start the hydraulic cylinder 7 and the motor 10 to drive the threaded block 11 to disengage from the mounting block 12. Start the electronic balance 3 again and read the value after drying. The water content of the fuel can be obtained by comparing the initial value with the value after drying.

[0030] Working principle:

[0031] During processing, firstly, hydraulic cylinder 7 is activated, causing the adjusting frame 8 to rise, which in turn raises the top cover 23 and the rotating shaft 17. The biomass fuel to be tested is placed inside the evaporation tank shell 21. Then, hydraulic cylinder 7 is activated, causing the adjusting frame 8 to descend until the top cover 23 is engaged with the evaporation tank shell 21. Subsequently, hydraulic cylinder 7 and motor 10 are activated, causing the threaded block 11 to rotate in the reverse direction, thus separating the threaded block 11 from the mounting block 12. The electronic balance 3 is then activated to read the initial value. Subsequently, hydraulic cylinder 7 and motor 10 are activated again, causing the threaded block 11 to rotate in the forward direction, thus separating the threaded block 11 from the mounting block 12. After the fixed connection of 2 is established, the evaporator shell 5 is started to heat the evaporator tank shell 21, thereby drying the fuel inside the evaporator tank shell 21. A pair of limit bolts 14 are removed, and the motor 10 is started to drive the rotating shaft 17 to rotate, thereby cutting and stirring the fuel inside the evaporator tank shell 21 and accelerating its drying. After the drying process is completed, the limit bolts 14 are reinserted, and then the hydraulic cylinder 7 and the motor 10 are started to drive the threaded block 11 to disengage from the mounting block 12. The electronic balance 3 is started again to read the value after drying. The water content of the fuel can be obtained by comparing the initial value with the value after drying.
