[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a mixing device for sintering biomass fuel, comprising a bottom plate 1, both ends of the bottom plate 1 surface are fixedly connected with support frames a2, a shaking assembly 8 is arranged on the surface of the rear end of the bottom plate 1, the inner walls of the two groups of support frames a2 away from the bottom plate 1 are slidably connected with guide rods 3, a mixing tank 4 is fixedly connected between the two groups of guide rods 3, and the guide rods 3 are arranged on both sides of the mixing tank 4 so as to slide on the inner wall of the top of the support frame a2, so that when the shaking assembly 8 drives the mixing tank 4 to shake back and forth, the mixing tank 4 can only move forward and backward, and It will not separate from the two groups of support frames a2, and the mixing tank 4 is also supported as a whole by two groups of guide rods 3. At the same time, an observation window is provided on the surface of the mixing tank 4, so as to facilitate the observation of the internal sintering biomass fuel mixing. Feed ports 5 are provided on both sides of the top of the mixing tank 4. The sintering biomass fuel to be mixed can be classified and discharged through the two groups of feed ports 5. A discharge port 6 is provided at the bottom end of the outer wall of the mixing tank 4, and a valve is provided on the surface of the discharge port 6. By opening the valve, the sintering biomass fuel that has been completely mixed in the mixing tank 4 can be discharged.

[0039] Reference Figure 2 - Figure 4The inner wall of the mixing tank 4 is provided with a mixing mechanism 7, which includes a semi-toothed ring 71. The bottom end of the outer wall of the semi-toothed ring 71 is fixedly connected to the top of the outer wall of the mixing tank 4. The shape of the semi-toothed ring 71 is less than one hundred and sixty degrees of a semicircle. By setting the shape of the semi-toothed ring 71 to be less than a semicircle, the three sets of gears 76 will not mesh with the semi-gear 73 when rotating and meshing with it, thereby causing a stuck tooth. The output shaft of the motor 74 penetrates and is rotatably connected to the inner wall of the semi-gear 73. By passing the output shaft of the motor 74 through the inner wall of the semi-gear 73, the semi-gear 73 will not be driven to rotate synchronously when the driving connecting plate 75 rotates. The outer wall of the semi-toothed ring 71 A connecting frame 72 is fixedly connected to the top of the wall, and a half gear 73 is fixedly connected to the bottom end of the connecting frame 72 away from one end of the half gear ring 71. By setting a connecting frame 72 between the half gear ring 71 and the half gear 73, the half gear ring 71 and the half gear 73 can be fixed in series, and the position of the motor 74 is also supported. The shape of the half gear 73 is one hundred and eighty degrees. By setting the shape of the half gear 73 to one hundred and eighty degrees of a semicircle, the three sets of gears 76 will continue to mesh with the half gear 73 after a short distance after the half gear ring 71 is disengaged, thereby preventing the teeth from getting stuck, and the tooth spacing between the half gear ring 71, the half gear 73 and the gear 76 is matched.

[0040] Reference Figure 3 and Figure 4The top of the connecting frame 72 away from the half gear ring 71 is fixedly connected to a motor 74, and the output shaft of the motor 74 is fixedly connected to a connecting plate 75. The connecting plate 75 is shaped as a group of round blocks and three groups of brackets, and the output shaft of the motor 74 is fixed to the central axis of the round block. The top of the outer wall of the connecting plate 75 is rotatably connected to three groups of gears 76. The three groups of gears 76 mesh with the outer wall of the half gear 73. The meshing between the two makes the gear 76 rotate synchronously around the center of the circle following the connecting plate 75. , and will mesh with the half gear 73 when passing through it, so that the three sets of half gears 73 will rotate clockwise while rotating around the center of the circle, so that the three sets of rotating shafts 77 drive the stirring rod 78 to fully mix the sintering biomass fuel inside the mixing tank 4, and the three sets of gears 76 mesh with the inner side wall of the half gear ring 71. The meshing between the two makes the three sets of half gears 73 pass through the inner wall of the half gear ring 71 when they are no longer meshed with the half gear 73, so that the three sets of half gears 73 can pass through the inner wall of the half gear ring 71, The gears 76 are meshed with the teeth on the inner wall of the half gear ring 71, so that the three gears 76 drive the bottom shaft 77 and the stirring rod 78 to rotate counterclockwise synchronously, so that the internal sintering biomass fuel is fully stirred and mixed. The rotation center axes of the three gears 76 are fixedly connected to the shaft 77. A cavity is opened at the top of the mixing tank 4. The shaft 77 penetrates and is slidably connected to the inner wall of the cavity at the top of the mixing tank 4. By opening a cavity at the top of the mixing tank 4, the gears 76 are prevented from being entangled. When the rotation center point of the connecting disk 75 rotates around the center of the circle, it will be blocked by the top of the mixing tank 4. The connecting disk 75 is rotatably connected to the top of the inner wall of the mixing tank 4. The top of the outer wall of the three sets of rotating shafts 77 is rotatably connected to the bottom end of the outer wall of the connecting disk 75. The outer wall of the rotating shaft 77 is fixedly connected to multiple sets of stirring rods 78. The multiple sets of stirring rods 78 are fixed to the outer wall of the rotating shaft 77 in an inclined state, so that when the rotating shaft 77 rotates, it will drive the multiple sets of stirring rods 78 to fully mix, stir and disperse the sintering biomass fuel inside.

[0041] Reference Figure 2 and Figure 5The shaking assembly 8 includes two groups of support frames b81, and the two groups of support frames b81 are fixedly connected to the surface of the rear end of the bottom plate 1. The end of the upper group of guide seats 84 away from the L-shaped block 83 is fixedly connected to the outer wall of the mixing tank 4. Through the drive of the double-axis motor 82, its output shaft can drive the upper and lower groups of L-shaped blocks 83 to rotate synchronously, so that the L-shaped block 83 can slide on the inner wall of the guide groove of the guide seat 84, so as to push the mixing tank 4 to slide between the two groups of support frames a2, so as to avoid the internal sintering biomass fuel from being too small in density when unloading through the unloading port 6, thereby adsorbing together and causing blockage of the unloading port 6. A double-axis motor 82 is fixedly connected between the two groups of support frames b81. The double-axis motor 82 is a Yaskawa model Sig in the prior art. The ma-five series is provided with two sets of upper and lower output shafts. The output shaft of the dual-axis motor 82 is fixedly connected with the upper and lower sets of L-shaped blocks 83. The outer walls of the two sets of L-shaped blocks 83 are slidably connected with the guide seats 84. The inner walls of the guide seats 84 are provided with guide grooves that fit the L-shaped blocks 83, so that when the L-shaped blocks 83 rotate, the protrusions at the top thereof will rotate around the center of the circle, thereby sliding on the inner wall of the guide seats 84, so that the upper and lower sets of guide seats 84 will push the corresponding mixing tanks 4 and the placement plates 9 to reciprocate. The outer wall of the lower set of guide seats 84 is fixedly connected with the placement plates 9, and the placement plates 9 are pushed to reciprocate by the lower set of guide seats 84, thereby avoiding that when the inside of the collecting box 10 is discharged through the discharge port 6, the sintering biomass fuel after mixing will be accumulated on one side.

[0042] Reference Figure 2 and Figure 5 The inner wall of the placement plate 9 is slidably connected with a collecting box 10, and a handle is provided on the surface of the collecting box 10, through which the collecting box 10 can be conveniently taken out from the inner wall of the placement plate 9 as a whole, so as to facilitate the removal of the sintering biomass fuel after the mixing is completed. The front end of the collecting box 10 is fixedly connected with a fixing block 11, and the inner wall of the fixing block 11 is penetrated and slidably connected with a positioning rod 12, which is made of stainless steel, and the inner wall of the fixing block 11 is provided with a guide groove that fits the positioning rod 12, so that the positioning rod 12 can only move up and down on the inner wall of the fixing block 11 and cannot be separated. Its inner wall and the outer wall of the placement plate 9 are in contact with the outer walls of the bottom ends of the two groups of support frames a2. By arranging a triangular block between the two groups of support frames a2, the moving position of the placement plate 9 can be guided so that it can only move forward and backward. The bottom end of the outer wall of the placement plate 9 is in contact with the surface of the bottom plate 1. A through hole is opened on the surface of the placement plate 9. The bottom end of the outer wall of the positioning rod 12 is plugged into the inner wall of the through hole. The connection between the two can fix the position of the collection box 10 on the inner wall of the placement plate 9, thereby preventing the collection box 10 from detaching from the inner wall of the placement plate 9 during the reciprocating shaking of the placement plate 9.

[0043] Working principle: When using the mixing device for sintering biomass fuel, firstly, the sintering biomass fuel to be mixed is added into the mixing tank 4 through the two groups of feed ports 5, and the motor 74 is started. The output shaft of the motor 74 drives the connecting plate 75 to rotate, and the connecting plate 75 drives the three groups of gears 76 to rotate around the center of the circle. When one of the three groups of gears 76 passes through the half gear 73, since the gear 76 is meshed with the half gear 73, the gear 76 will rotate clockwise while rotating around the center of the circle. At this time, the three groups of rotating shafts 77 drive the stirring rod 78 to rotate clockwise, so as to stir the sintering biomass fuel inside the mixing tank 4. The materials are stirred and mixed, and the rear two sets of gears 76 will follow and mesh with the half gear 73. At the same time, after the first set of gears 76 cancels the meshing with the half gear 73, it will mesh with the tooth block on the inner wall of the half gear ring 71 after a short distance. Since the gear 76 is meshed with the half gear ring 71, the current gear 76 will drive the bottom shaft 77 and the stirring rod 78 to rotate counterclockwise synchronously, and continue to fully stir and mix the internal sintering biomass fuel. Through this clockwise and counterclockwise alternating rotation method, the stirring rod 78 can fully mix, stir and disperse the sintering biomass fuel inside the mixing tank 4.

[0044] The mixing condition of the internal fuel can be observed through the observation window on the surface of the mixing tank 4. After the mixing is completed, the valve of the discharge port 6 is opened to prepare for discharge, and the dual-axis motor 82 of the shaking assembly 8 is started at the same time. The dual-axis motor 82 drives the L-shaped block 83 to rotate, and the protrusion at the top of the L-shaped block 83 rotates around the center of the circle and slides on the inner wall of the guide seat 84, so that the mixing tank 4 is reciprocated and shaken on the top of the support frame a2 through the guide rods 3 on both sides. In this way, when discharging through the discharge port 6, the sintering biomass fuel inside is not too small and is adsorbed together, causing the discharge port 6 to be blocked. The placement plate 9 will be at the bottom of the two groups of support frames a2 Reciprocating shaking is performed to prevent the sintering biomass fuel from piling up on one side after mixing. The mixed fuel is discharged from the discharge port 6 into the collecting box 10. The collecting box 10 is fixed on the placement plate 9 by a positioning rod 12 to prevent it from detaching during shaking. When the collecting box 10 needs to be taken out, the positioning rod 12 is pulled upward to detach from the through hole on the placement plate 9, and the collecting box 10 is taken out from the inner wall of the placement plate 9 by the handle, so as to facilitate the subsequent processing of the sintering biomass fuel after mixing. The whole equipment realizes efficient mixing and smooth discharge of the sintering biomass fuel through the coordinated work of the mixing mechanism 7 and the shaking assembly 8.
