Description

Technical Field

[0001] This utility model relates to the field of biomass fuel processing, and in particular to a biomass fuel processing raw material mixing device. Background Technology

[0002] Biomass fuel refers to the combustion of biomass materials as fuel, which are generally agricultural and forestry wastes such as straw, sawdust, bagasse, and rice husks. The processing of biomass fuel requires processes such as crushing, mixing, extrusion, and drying to produce various shapes (such as blocks and pellets), thus requiring the use of mixing equipment.

[0003] However, traditional biomass fuel processing raw material mixing devices can only achieve local shear mixing due to the large differences in biomass raw material density and uneven particle size. They are prone to stratification due to gravity settling, resulting in light materials floating and heavy materials sinking, which leads to uneven fuel composition. When a crushing roller is added, the crushing roller is easily entangled by long fiber raw materials or long strip-shaped foreign objects mixed in the raw materials, affecting the crushing effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biomass fuel processing raw material mixing device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a biomass fuel processing raw material mixing device, comprising a housing, a power distribution box fixedly connected to the left side of the housing, two evenly distributed partitions fixedly connected inside the power distribution box, motors fixedly connected to the top of the partitions and the inner wall of the bottom of the power distribution box, main gears fixedly connected to the output ends of three motors, a secondary gear meshing with the right side of the main gears and rotatably connected to the power distribution box, the output ends of the three motors penetrating the housing and fixedly connected to the crushing roller and the spiral roller and the rotating shaft respectively, and comb teeth fixedly connected to the surface of the spiral roller. The rotating shaft is rotatably connected to a uniformly distributed drive box. A triangular fixing plate is fixedly connected to the lower part of the inner wall of the drive box, and the bottom of the triangular fixing plate is fixedly connected to the drive box. Three uniformly distributed driving bevel gears are fixedly connected to the surface of the rotating shaft, and the driving bevel gears are rotatably connected inside the drive box. The bottom of each drive box is rotatably connected to a transmission shaft, and one end of the transmission shaft is rotatably connected to the box body. A driven bevel gear is fixedly connected to the top of the transmission shaft, and the driven bevel gear is rotatably connected inside the drive box. The driving bevel gear and the driven bevel gear are meshed together. A stirring rod is fixedly connected to the surface of the transmission shaft.

[0006] As a further description of the above technical solution: an air compressor is fixedly connected to the bottom of the box, an aeration pipe is fixedly connected to the exhaust port of the air compressor and the aeration pipe passes through and is fixedly connected to the bottom of the inner wall of the box, and micro aeration holes are fixedly connected to the surface of the aeration pipe.

[0007] As a further description of the above technical solution: a hinge is fixedly connected to the surface of the distribution box, and a protective door is fixedly connected to the hinge. A door handle is provided on the surface of the protective door.

[0008] As a further description of the above technical solution: a discharge port is connected through and fixedly connected to the right side of the box, and a material collection trough is provided below the discharge port.

[0012] This utility model has the following beneficial effects:

[0013] 1. The present invention proposes a biomass fuel processing raw material mixing device. First, two spiral rollers are installed above the crushing roller. The spiral rollers disperse the raw materials that are in clumps or clusters, reducing the working pressure on the crushing roller below. Because the crushing roller is easily entangled by long fiber raw materials or long strip-shaped foreign objects mixed in the raw materials, affecting the crushing effect, comb teeth are installed on the surface of the upper spiral roller to scrape out the long fibers and long strip-shaped foreign objects mixed in the raw materials in real time, preventing them from falling into the crushing roller below, thus solving the risk of the crushing roller being entangled. The raw materials are pre-treated by the spiral rollers before crushing and mixing, which can greatly improve the working efficiency.

[0014] 2. The present invention proposes a biomass fuel processing raw material mixing device, which fluidizes light materials by installing an air compressor at the bottom of the box and an aeration pipe at the bottom of the box, and forms a gas-solid two-phase mixture by mechanical stirring. When the heavy materials sink, they are blown upward by high-pressure gas sprayed from the micro aeration holes set on the aeration pipe, so that the heavy materials are stirred again by the stirring equipment, which suppresses the gravity stratification phenomenon caused by the large density difference between light and heavy materials and improves the uniformity of stirring.

The output ends of the three motors 14 are fixedly connected to a main gear 22. A secondary gear 13 is meshed with the right side of the main gear 22 and is rotatably connected to the power distribution box 5. The power of the main gear 22 is transmitted to the secondary gear 13 through the gear movement. The output ends of the three motors 14 pass through the housing 1 and are fixedly connected to a crushing roller 17 and a spiral roller 15, respectively, and a rotating shaft 10. The surface of the spiral roller 15 is fixedly connected to a comb tooth 16 to scrape out long fibers and long strip-shaped foreign objects mixed in the raw material in real time, preventing them from falling into the crushing roller 17 below. A uniformly distributed partition 27 is rotatably connected through the rotating shaft 10. The evenly distributed drive box 23 transmits power through its internal structure. A triangular fixing plate 28 is fixedly connected to the lower part of the inner wall of the box 1, and the bottom of the triangular fixing plate 28 is fixedly connected to the drive box 23 to fix the position of the drive box 23 and achieve a stabilizing effect. The triangular top design can prevent material from accumulating on the top of the drive box 23. Three evenly distributed active bevel gears 24 are fixedly connected to the surface of the rotating shaft 10, and the active bevel gears 24 are rotatably connected inside the drive box 23. The horizontal motion is transmitted into vertical rotational motion through the meshing motion of the gears. The bottom of the drive box 23 is rotatably connected to the transmission shaft 18, and one end of the transmission shaft 18 is rotatably connected to the box 1. The top of the transmission shaft 18 is fixedly connected to the driven bevel gear 25, and the driven bevel gear 25 is rotatably connected inside the drive box 23. The active bevel gear 25 and the driven bevel gear 24 are meshed. A stirring rod 19 is fixedly connected to the surface of the transmission shaft 18 to stir and mix the raw materials.

[0026] An air compressor 12 is fixedly connected to the bottom of the housing 1 to provide high-pressure gas. An aeration pipe 20 is fixedly connected to the exhaust port of the air compressor 12, and the aeration pipe 20 passes through and is fixedly connected to the bottom of the inner wall of the housing 1. Micro aeration holes 21 are fixedly connected to the surface of the aeration pipe 20. Gas is delivered to the micro aeration holes 21 through the aeration pipe 20 installed at the bottom of the housing 1 to spray out high-pressure gas, causing the heavy materials to be agitated again by the mixing equipment. A hinge 8 is fixedly connected to the surface of the distribution box 5, and a protective door 26 is fixedly connected to the hinge 8. A door handle 9 is provided on the surface of the protective door 26. The power distribution box 5 protects the movement of the motor 14 inside and prevents accidental contact. The right side of the box 1 has a discharge port 4 that runs through and is fixedly connected to it. Below the discharge port 4, there is a material collection trough 3 to collect the mixed materials. The air inlet of the air compressor 12 is fixedly connected to a filter screen 11 to prevent external impurities from clogging the air compressor 12.

[0027] Working principle: The start switch in switch box 7 is triggered. The distribution box 5 is divided into three layers by two partitions 27. Motors 14 are installed on the top of partitions 27 and the bottom inner wall of the distribution box 5. Motor 14 starts rotating, and its output drives the main gear 22 to rotate. The main gear 22 drives the auxiliary gear 13 to rotate, causing the spiral roller 15 to rotate. The spiral roller 15 breaks up the lumps of raw material. The comb teeth 16 on the surface of the spiral roller 15 scrape off long strips of foreign matter from the raw material, preventing them from falling into the lower crushing roller 17 and becoming entangled. The raw material pre-treated by the spiral roller 15 falls into the lower crushing roller 17 for further crushing. The crushed raw material falls to the bottom, and the output of motor 14 in the lower layer of the distribution box 5 rotates... The main gear 22 is driven to move, which in turn drives the secondary gear 13. The rotating shaft 10 driven by the gear drives the active bevel gear 24 inside the drive box 23 to rotate, which in turn drives the driven bevel gear 25 at the top of the transmission shaft 18 to rotate. The transmission shaft 18 is driven to rotate by the driven bevel gear 25, which in turn drives the stirring rod 19 to stir the crushed raw materials. During stirring, the micro aeration holes 21 on the surface of the aeration pipe 20 at the bottom of the inner wall of the box 1 are supplied with compressed gas by the air compressor 12 at the bottom of the box 1, which blows the heavy raw materials that have sunk to the bottom back to the stirring rod 19 above for stirring, so that the light and heavy raw materials are fully mixed. The stirred raw materials are discharged from the discharge port 4 and fall into the collection trough 3 below.
