[0001] The utility model belongs to the technical field of straw crushing, in particular to a straw crusher for biomass fuel production. Background Art

[0002] Biomass fuel refers to a new type of clean fuel that is directly burnt after the biomass material is processed by compression molding, crushing, etc. to form a solid fuel with a certain shape and density. Biomass fuel is a block-shaped environmentally friendly new energy source produced by processing straw, rice straw, rice husk, peanut shell, corn cob, oil tea shell, cottonseed shell, etc. and "three wastes". In order to meet its production needs, straw and other materials are often crushed into small raw materials before processing, so straw crusher has become an indispensable processing equipment;

[0003] At present, when using a disc crusher to crush straw, the material is often discharged directly, and it is impossible to determine whether the discharged material is crushed evenly, resulting in unqualified straw in the discharged material, affecting the subsequent production quality of biomass fuel;

[0004] In order to solve the above problems, the present application proposes a straw crusher for biomass fuel production. Utility Model Content

[0027] See also Figure 1-4 As shown, the utility model is a straw crusher for biomass fuel production, comprising: a crusher 1 and a conveyor belt 2 at the bottom of which the crushed straw raw materials appear;

[0028] A material tray 3 for placing straw is provided inside the upper end of the crusher 1, a limiting seat 4 for guiding the straw outward is provided inside the material tray 3, and a hot air blower 15 for applying hot air to the straw to form a drying process is provided inside the limiting seat 4;

[0029] A layered inner ring cylinder 7 is provided inside the crusher 1, an inner filter frame 8 for discharging materials is provided at the lower end of the inner ring cylinder 7, an outer filter frame 10 is provided between the crusher 1 and the inner ring cylinder 7, and is staggered with the inner filter frame 8 to perform secondary crushing on the incompletely crushed straw, and a positioning frame 17 is provided between adjacent outer filter frames 10, and a brush body 18 for cleaning the mesh is provided on the inner side of the positioning frame 17;

[0030] The present embodiment provides a straw crushing, discharge and drying mechanism, which increases the contact time with hot air through the rotational movement of the straw when it is put in, so as to remove the moisture contained in the straw and keep it dry, facilitate the subsequent crushing processing, and prevent the occurrence of entanglement of the tool. Secondly, the outer filter frame 10 and the inner filter frame 8 that are offset from each other can be used to perform secondary crushing of the straw to meet the predetermined discharge requirements. Secondly, the double-layer screening method can effectively prevent the insufficiently crushed straw from being discharged, which is beneficial to the subsequent use of biomass fuel production.

[0031] Among them, a shifting plate 5 for moving the straw is arranged on the outer side of the limiting seat 4, and a positioning notch 14 for the lower row of straw is opened inside one side of the material tray 3. The shifting plate 5 drives the straw to move above the positioning notch 14 and then automatically discharges the straw downward.

[0032] Among them, the upper end of the paddle 5 is provided with an air duct 6 for transmitting hot air, and both sides of the air duct 6 are provided with exhaust ducts 13 for guiding the hot air to blow toward the straw, so that the hot air blows directly on the surface of the straw to accelerate the removal of moisture.

[0033] Among them, an outer ring frame 9 for installing an outer filter frame 10 is arranged between the crusher 1 and the inner ring cylinder 7, and an inner convex seat 11 protruding from the plate body on one side of the outer ring frame 9 of a rotating mounting seat is arranged on the inner side of the crusher 1, and the outer side of the upper end of the outer ring frame 9 is a protruding tooth-shaped mechanism.

[0034] Among them, the crusher 1 is also provided with a transmission gear 12 meshingly connected to the outer side of the upper end of the outer ring frame 9 to drive the outer filter frame 10 to rotate and shift with the inner filter frame 8, while driving a positioning frame 17 and a brush body 18 inside it to clear the mesh of the inner filter frame 8.

[0035] The upper end of the material tray 3 is provided with a rotating motor 16 for driving the limit seat 4 to rotate.

[0036] The bottom of the crusher 1 is an inverted cone-shaped opening structure, which is connected to the top of one end of the conveyor belt 2.

[0037] It can be understood that the utility model can put the straw into production operation without long-term drying, thus shortening the production cycle and preventing the occurrence of knife entanglement. Secondly, when discharging the material, it can be aligned for secondary screening to prevent insufficiently crushed straw from being entrained and discharged, and at the same time, the discharged straw material can be secondary crushed to make the material quality uniform, which is conducive to subsequent production and processing.

[0038] A specific application of the operation process of this embodiment is as follows: when in use, first use the material tray 3 to block the input straw, then drive the rotating motor 16 to drive the limiting seat 4 and the dial plate 5 on its outer side to rotate, so that the straw is rotated and moved. In this process, the dial plate 5 arranged inside the limiting seat 4 is used to transmit hot air through the annular hollow mechanism at its bottom and the air guide 6 connected to the outside, and finally the hot air is guided to the surface of the straw through the exhaust pipe 13 to remove the moisture contained in the straw to achieve the drying effect. After this arrangement, the straw can be put into production operation without long-term drying, which shortens the time of drying. During the biomass fuel production cycle, it also avoids the situation where straw with excessive humidity causes blockage. The transmission gear 12 is further used to drive the outer filter frame 10 at its lower end to rotate through the outer ring frame 9 when discharging the crushed straw raw material, so that its inner surface scrapes the outer surface of the inner filter frame 8, and the straw that is not fully crushed is secondary crushed. At the same time, the brush body 18 on the inner side of the positioning frame 17 can also be used to conveniently push out the straw inside the outer filter frame 10, effectively avoiding the occurrence of material blockage, enriching the equipment's use functions while reducing the difficulty of work, and facilitating the straw crushing operation.
