Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel molding, in particular to a biomass fuel molding device. Background Art

[0002] Biomass shaped fuel uses agricultural and forestry waste as raw materials. It uses mechanical pressure to compress the original loose and amorphous raw materials into solid shaped energy with a certain shape and high density. It has the advantages of small size, convenient storage and transportation, stable combustion and high combustion efficiency.

[0003] A Chinese patent discloses a biomass fuel molding device (authorization announcement number CN218012467U). This patented technology crushes and mixes the raw materials by rotating the stirring rod and the twisted blades, thereby improving the effect of crushing and mixing the raw materials, thereby improving the quality of biomass fuel molding. However, in the extrusion molding structure in the extrusion box, a discharge port is directly opened on one side of the box body. When the extrusion plate extrude the crushed raw materials, since there is no obstruction at the discharge port, the unformed bulk material will be squeezed out, and the molding effect cannot be achieved. Therefore, those skilled in the art provide a biomass fuel molding device to solve the problems raised in the above background technology. Utility Model Content

[0006] Preferably, a feed hopper is installed on the top of the extrusion box, a hydraulic rod is fixedly installed on the side of the extrusion box away from the discharge port, an extrusion push plate is provided in the extrusion box, the output end of the hydraulic rod passes through the extrusion box and is fixedly connected to the extrusion push plate, and the hydraulic rod and the extrusion push plate are used to extrude the raw materials into plasticity and discharge them.

[0007] Preferably, a motor is provided on one side of the fixed plate, and a clamping block is installed on the motor, and the clamping block is slidably engaged with the second clamping slot. Since the motor is slidably engaged with the second clamping slot through the clamping block, the motor will not rotate while moving up and down.

[0008] Preferably, the rotating shaft is slidably sleeved with the through groove, the gear ring is slidably engaged with the first slot, and the gear ring is engaged with the teeth. When the rotating shaft rotates, it is affected by the gear ring and the teeth in the first slot and moves downward, thereby driving the roller to move downward and rotate on its own, so that when the roller moves to the discharge port, the protrusion is engaged and connected with the discharge port.

[0011] Compared with the existing technology, the present invention provides a biomass fuel molding device with the following beneficial effects:

[0012] Through design, the motor drives the rotating shaft, and when the rotating shaft rotates, it is affected by the gear ring and the teeth in the first slot to move downward, thereby driving the roller to move downward and rotate, so that when the roller moves to the discharge port, the protrusion engages with the discharge port. After the raw material is squeezed into shape by the extrusion push plate, the motor moves the roller back to the top. At this time, the extrusion push plate continues to extrude, and squeezes the raw material after preliminary extrusion out of the discharge port. This method avoids the problem of unformed bulk material being squeezed out during extrusion and discharging, resulting in the problem of being unable to form and wasting.

The output end of the hydraulic rod 18 passes through the extrusion box 1 and is fixedly connected to the extrusion push plate 19. The hydraulic rod 18 and the extrusion push plate 19 are used to extrude the raw materials into plasticity and discharge them. A discharge port 3 is opened on one side of the extrusion box 1. Please refer to Figure 3 、 Figure 4 、 Figure 5 , fixed plates 4 are installed on both sides of the discharge port 3, a roller 9 is provided between the two fixed plates 4, a protrusion 10 is installed on the roller 9, a rotating shaft 11 is installed at both ends of the roller 9, a gear ring 12 is installed on the rotating shaft 11, an annular groove 13 is provided at both ends of the roller 9, a cutting knife 14 is provided below the roller 9, and a positioning shaft 15 is installed on the inner side of the top of both ends of the cutting knife 14, a through groove 5 is provided on the fixed plate 4, a first card groove 6 is provided in the through groove 5, and a tooth 601 is installed on one side inner wall of the first card groove 6, a slide groove 8 is provided on the side of the fixed plate 4 facing the roller 9, and a second card groove 7 is provided on the side of the fixed plate 4 away from the roller 9;

[0021] See also Figure 3 、 Figure 4 、 Figure 5A motor 16 is provided on one side of the fixed plate 4, and a clamping block 17 is installed on the motor 16. The clamping block 17 is slidably engaged with the second clamping slot 7. Since the motor 16 is slidably engaged with the second clamping slot 7 through the clamping block 17, the motor 16 will not rotate while moving up and down. The rotating shaft 11 is slidably engaged with the through slot 5, and the gear ring 12 is slidably engaged with the first clamping slot 6. The gear ring 12 is engaged with the teeth 601, and the rotating shaft 11 is rotated. Affected by the tooth ring 12 and the teeth 601 in the first slot 6, it moves downward, thereby driving the roller 9 to move downward and rotate, so that when the roller 9 moves to the discharge port 3, the protrusion 10 is engaged with the discharge port 3, and the two ends of the cutting knife 14 are slidably engaged with the slide groove 8, and the positioning shaft 15 is slidably connected to the annular groove 13. The cutting knife 14 is in a "U" shape. When the roller 9 moves downward to block the material, the cutting knife 14 will first cut the raw material that has been plastically discharged.

[0022] In the present invention, a feed hopper 2 for feeding is installed above the extrusion box 1, and a hydraulic rod 18 is installed on one side of the extrusion box 1. The hydraulic rod 18 passes through the extrusion box 1 and is connected to the extrusion push plate 19 in the extrusion box 1. A discharge port 3 is opened on the other side away from the hydraulic rod 18 for extruding the raw materials into plasticity and discharging them;

[0023] A fixed plate 4 is installed at one end of the extrusion box 1 where a discharge port 3 is opened, a roller 9 is arranged between the two fixed plates 4, and the roller 9 is provided with the same number of protrusions 10 as the discharge port 3. When the raw material needs to be extruded, the motor 16 drives the rotating shaft 11. When the rotating shaft 11 rotates, it is affected by the gear ring 12 and the teeth 601 in the first card slot 6 to move downward, thereby driving the roller 9 to move downward and rotate, so that when the roller 9 moves to the discharge port 3, the protrusion 10 is engaged with the discharge port 3. After the raw material is squeezed into shape by the extrusion push plate 19, the motor 16 moves the roller 9 back to the top. At this time, the extrusion push plate 19 continues to squeeze and squeezes the initially extruded raw material out of the discharge port 3. This method avoids the unformed bulk material from being squeezed out during extrusion and causing waste;

[0024] Since the motor 16 is slidably engaged with the second slot 7 via the clamping block 17, the motor 16 will not rotate while moving up and down.

[0025] Annular grooves 13 are provided at both ends of the roller 9 with the rotating shaft 11, and a sliding groove 8 is provided on the side wall of the fixed plate 4 facing the annular groove 13, and a cutting knife 14 is slidably engaged in the sliding groove 8. The cutting knife 14 is "U"-shaped, and a positioning shaft 15 is installed on the inner side of the top of both ends, and the positioning shaft 15 is rotatably engaged with the annular groove 13. Therefore, when the roller 9 moves downward to block the material, the cutting knife 14 will first cut the raw material that has been plastically discharged, and then block the discharge port 3 again to avoid the problem of loose raw materials during discharge.
