Description

Technical Field

[0001] This utility model relates to the technical field of biomass pellet production equipment, specifically a biomass pellet forming equipment. Background Technology

[0002] Chinese Patent CN219968956U discloses a biomass pellet fuel forming and extrusion device, including a housing. A forming component is fixedly installed on the left side of the bottom of the housing's inner cavity, a vibration component is installed on the right side of the bottom of the housing's inner cavity, a cleaning component is fixedly installed on the left side of the housing, an electric cylinder is connected through the top left side of the housing, a pressure plate is fixedly installed at the bottom of the electric cylinder, and a mixing chamber is fixedly installed on the right side of the top of the housing's inner cavity. Heating components are fixedly installed on both sides of the mixing chamber's inner cavity. Through the cooperation of the electric cylinder, forming component, cleaning component, heating component, mixing component, and vibration component, the biomass raw material can be fully heated and dried, removing moisture and thus ensuring more complete combustion of the solid fuel pellets. This results in more complete combustion of the biomass raw material, reducing air pollution and improving resource utilization.

[0003] The specification of this utility model also states that "when the electric cylinder 12 rises to the corresponding position, the telescopic end of the first electric telescopic rod 16 is controlled to push the fixed plate 17 and the brush bristles 15. Under the action of the brush bristles 15, the raw material residue adhering to the bottom of the pressure plate 13 is cleaned off, achieving a cleaning effect." However, when cleaning the residue on the pressure plate, most of the residue falls directly back into the extrusion frame. Since the residue itself is formed by extrusion, the size of the residue is generally small. After falling back into the extrusion frame, the residue will be discharged through the through hole and the discharge port, mixing with the finished product. A small portion of the residue will be scattered inside the box due to the pushing force of the brush bristles. Moreover, since the brush bristles face upwards, some residue will get stuck on the brush bristles. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a biomass pellet forming equipment, which achieves the following technical effect: when cleaning the residue on the pressing plate, the residue can be collected and fall into the collection box.

[0005] A biomass pellet forming device includes a box, an extrusion frame, an electric cylinder, and a pressure plate. A motor and a rotating tube are mounted at the top of the box. The motor is fixedly installed at the top of the box, and a drive wheel is fixedly mounted on the motor's output shaft. The rotating tube is rotatably connected to the box via a bearing. The top of the rotating tube is located above the box and is fitted with a driven wheel. The driven wheel and the drive wheel are connected by a transmission belt. The bottom end of the rotating tube passes into the box and is fixedly mounted on a turntable. The electric cylinder is fixedly installed at the top edge of the turntable. The piston rod of the electric cylinder passes vertically downward through the turntable and is fixedly mounted on a lifting plate. A first electric telescopic rod is installed at the top edge of the lifting plate. The piston rod of the first electric telescopic rod passes vertically downward through the lifting plate and is hinged to a slider. A vertical rod is fixed at the bottom of the lifting plate, and the bottom end of the vertical rod is hinged to the center of the top of the pressure plate. Two spaced-apart mounting blocks are fixed at the top edge of the pressure plate, and a guide rod that slides through the slider is fixedly connected between the two mounting blocks.

[0006] A second electric telescopic rod is installed on the outer side wall of the box. The piston rod of the second electric telescopic rod is inserted into the box at an angle and a movable plate corresponding to the pressure plate is fixed thereon. A scraper for cleaning the bottom surface of the pressure plate is installed at the top of the movable plate.

[0007] The inside of the box also contains a collection box corresponding to the scraper.

[0008] By adopting the above technical solution, when it is necessary to clean the residue on the bottom surface of the pressure plate, the motor is started. The output shaft of the motor rotates, driving the drive wheel to rotate. The drive wheel drives the driven wheel to rotate via a transmission belt. The driven wheel drives the rotating tube to rotate. The rotating tube drives the turntable to rotate 180°. After the turntable rotates 180°, the positions of the electric cylinder, lifting plate, first electric telescopic rod, lifting plate, vertical rod, and pressure plate all change, corresponding to the top of the collection box. Then, the first electric telescopic rod is started, the piston rod of the first electric telescopic rod retracts, driving the slider to move upward, and the slider slides along the guide rod. This lifts one end of the pressure plate, and the pressure plate rotates around the bottom end of the vertical rod as the center, causing the pressure plate to tilt. Then, the second electric telescopic rod is started, the piston rod of the second electric telescopic rod extends, driving the moving plate and scraper to move. The scraper scrapes off the residue on the bottom surface of the pressure plate. All the residue will fall into the collection box. This utility model ensures that when cleaning residue on the pressure plate, the residue can fall into the collection box in a concentrated manner.

[0009] A further feature of this invention is that the top of the movable plate is provided with a groove, the bottom of the scraper is slidably inserted into the groove and a spring is fixedly connected between the scraper and the bottom of the groove, and the top of the scraper is provided with an inclined surface corresponding to the side wall of the pressure plate.

[0010] By adopting the above technical solution, when the scraper moves downwards at an angle, its inclined surface presses against the side of the pressure plate. The force on the inclined surface can be decomposed into a force acting towards the inside of the groove. Under the action of this force, the scraper moves into the groove, and the spring is compressed to form a rebound force towards the outside of the groove. This allows the scraper to smoothly align with the bottom surface of the pressure plate, and under the action of the spring's rebound force, the top of the scraper is tightly attached to the bottom surface of the pressure plate. This ensures that the residue on the bottom surface of the pressure plate can be completely scraped off by the scraper.

[0011] Further features of this invention: The scraper includes a buffer plate and a cleaning plate. The bottom end of the buffer plate is slidably inserted into the groove. The spring is connected between the bottom end of the buffer plate and the bottom of the groove. The top end of the buffer plate extends out of the groove and is fixed with an insert plate. The bottom end of the cleaning plate has a slot. The cleaning plate is sleeved on the outside of the insert plate through the slot and fixed with bolts and nuts.

[0012] By adopting the above technical solution, when the top of the cleaning plate is damaged by friction due to long-term use, the cleaning plate can be removed from the buffer plate by unscrewing the bolts and nuts. Similarly, the cleaning plate can be installed by fitting it onto the outside of the insert plate through the slot and securing it with bolts and nuts. This facilitates the replacement of the cleaning plate.

[0013] A further feature of this invention is that a positioning frame for positioning the collection box is fixed on the inner bottom wall of the box.

[0014] By adopting the above technical solution, when placing the collection box, the bottom of the collection box is inserted into the positioning frame, which can quickly position the collection box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] A biomass pellet forming device is disclosed. When cleaning residue from the pressing plate, the residue can be collected and fall into the collection box, preventing it from falling back into the extrusion frame or scattering inside the box. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A biomass pellet forming device, such as Figures 1-4 As shown, it includes a box body 1, a squeezing frame 2, a collection box 3, a transposition structure, a squeezing structure, and a cleaning structure.

[0024] A door is provided on the front of the box 1. The collection box 3 and the squeezing frame 2 are both placed on the inner bottom wall of the box 1 and are spaced apart on the left and right.

[0025] The housing 1 and the extrusion frame 2 are mature existing technologies and will not be specifically described in this embodiment. Furthermore, the technical problem to be solved in this embodiment is unrelated to how to feed material into the extrusion frame 2. Therefore, this embodiment will not specifically describe the method of feeding material into the extrusion frame 2. In this embodiment, the opening and closing door can be directly opened to feed material into the extrusion frame 2, or a structure such as the vibration component and mixing box described in the utility model patent with authorization announcement number CN219968956U (A Biomass Pellet Fuel Forming and Extrusion Equipment) can be used to feed material into the extrusion frame 2.

[0026] The switching structure is used to switch the position of the extrusion structure, allowing it to move between two positions: above the corresponding extrusion frame 2 and above the corresponding collection box 3. The switching structure includes a motor 4 and a rotating tube 5. The motor 4 is fixedly mounted on the top of the housing 1. A drive wheel 6 is fixed to the output shaft of the motor 4. The rotating tube 5 is rotatably connected to the housing 1 via bearings. The top of the rotating tube 5 is located above the housing 1 and is fixedly fitted with a driven wheel 7. The driven wheel 7 and the drive wheel 6 are connected by a transmission belt. The bottom end of the rotating tube 5 extends into the housing 1 and is fixedly fitted with a turntable 8.

[0027] The extrusion structure is used to extrude the raw material within the extrusion frame 2. The extrusion structure includes an electric cylinder 9 and a pressure plate 10. The electric cylinder 9 is fixedly installed at the top edge of the turntable 8. The piston rod of the electric cylinder 9 passes vertically downward through the turntable 8 and is fixed to a lifting plate 11. A first electric telescopic rod 12 is installed at the top edge of the lifting plate 11. The piston rod of the first electric telescopic rod 12 passes vertically downward through the lifting plate 11 and is hinged to a slider 13. A vertical rod 14 is fixed to the bottom end of the lifting plate 11. The bottom end of the vertical rod 14 is hinged to the center of the top of the pressure plate 10. Two spaced-apart mounting blocks 15 are fixed to the top edge of the pressure plate 10. A guide rod 16, which slides through the slider 13, is fixedly connected between the two mounting blocks 15.

[0028] The cleaning structure is used to clean residue from the bottom surface of the pressure plate 10. The cleaning structure includes a second electric telescopic rod 17, a moving plate 18, and a scraper 19. The second electric telescopic rod 17 is installed on the outer wall of the housing 1 and is inclined. The piston rod of the second electric telescopic rod 17 is inclinedly inserted into the housing 1 and fixed to the moving plate 18. The moving plate 18 corresponds to the pressure plate 10, and its top end has a groove 20. The bottom end of the scraper 19 is slidably inserted into the groove 20, and a spring 21 is fixedly connected between the scraper 19 and the bottom of the groove 20. The top end of the scraper 19 has an inclined surface 22 corresponding to the side wall of the pressure plate 10.

[0029] It is worth noting that the power cord on the electric cylinder 9 is threaded into the rotating tube 5 and then out through the top of the rotating tube 5 before being connected to the mains power. The power cord on the first electric telescopic rod 12 is threaded into the turntable 8, then out through the rotating tube 5 before being connected to the mains power. The portion of the power cord between the bottom of the turntable 8 and the first electric telescopic rod 12 should have sufficient length to allow for the vertical movement of the lifting plate 11.

[0030] Additionally, the scraper 19 includes a buffer plate 23 and a cleaning plate 24. The bottom end of the buffer plate 23 slides into the groove 20. A spring 21 connects the bottom end of the buffer plate 23 to the bottom of the groove 20. The top end of the buffer plate 23 protrudes from the groove 20 and is fixed with an insert plate 25. The bottom end of the cleaning plate 24 has a slot 26. The cleaning plate 24 is fitted onto the outside of the insert plate 25 through the slot 26 and secured with bolts and nuts. When the top end of the cleaning plate 24 is damaged by friction due to long-term use, the bolts and nuts can be removed to detach the cleaning plate 24 from the buffer plate 23. Similarly, the cleaning plate 24 is fitted onto the outside of the insert plate 25 through the slot 26 and secured with bolts and nuts, thus completing the installation of the cleaning plate 24. This facilitates the replacement of the cleaning plate 24.

[0031] A positioning frame 27 for positioning the collection box 3 is fixed on the inner bottom wall of the box body 1. When placing the collection box 3, the bottom end of the collection box 3 is inserted into the positioning frame 27, which can quickly position the collection box 3.

[0032] Working principle:

[0033] Extrusion molding preparation stage: The extrusion structure is located above the extrusion frame 2, and the pressure plate 10 is located directly above the extrusion frame 2.

[0034] Extrusion molding operation stage: After adding raw material into the extrusion frame 2, the electric cylinder 9 is activated. The piston rod of the electric cylinder 9 extends, causing the lifting plate 11 to move downward. The lifting plate 11 causes the vertical rod 14 to move downward. The vertical rod 14 causes the pressure plate 10 to move downward. The pressure plate 10 presses down on the raw material in the extrusion frame 2, thus extruding and molding the raw material.

[0035] Preparation stage for cleaning: The piston rod of the retracting electric cylinder 9 moves the pressure plate 10 upward to reset. Then, the first electric telescopic rod 12 is activated. The piston rod of the first electric telescopic rod 12 retracts, driving the slider 13 upward, and the slider 13 slides along the guide rod 16. This lifts one end of the pressure plate 10, and the pressure plate 10 rotates around the bottom end of the vertical rod 14, tilting the pressure plate 10 at the same tilt angle as the second electric telescopic rod 17. Then, the motor 4 is activated. The output shaft of the motor 4 rotates, driving the drive wheel 6 to rotate. The drive wheel 6 drives the driven wheel 7 to rotate via a transmission belt. The driven wheel 7 drives the rotating tube 5 to rotate. The rotating tube 5 drives the turntable 8 to rotate 180°, so that the extrusion structure is positioned above the collection box 3, the pressure plate 10 is positioned directly above the collection box 3, and corresponds to the scraper 19.

[0036] Cleaning operation phase: The second electric telescopic rod 17 is activated, and its piston rod extends, causing the moving plate 18 and scraper 19 to tilt downwards. As the scraper 19 tilts downwards, its inclined surface 22 presses against the side of the pressure plate 10. The force on the inclined surface 22 can be decomposed into a force acting towards the groove 20. Under this force, the scraper 19 moves into the groove 20, and the spring 21 is compressed, creating a rebound force towards the outside of the groove 20. This allows the scraper 19 to smoothly align with the bottom surface of the pressure plate 10, and under the rebound force of the spring 21, the top of the scraper 19 is tightly pressed against the bottom surface of the pressure plate 10. This ensures that the residue on the bottom surface of the pressure plate 10 can be completely scraped off by the scraper 19. All the residue scraped off the bottom surface of the pressure plate 10 falls into the collection box 3.

[0037] When cleaning residue from the pressure plate 10, the residue can be collected and fall into the collection box 3, preventing it from falling back into the extrusion frame 2 or scattering inside the box 1.
