Description

Technical Field

[0001] This application relates to the technical field of biomass fuels, and in particular to a biomass fuel preparation apparatus. Background Technology

[0002] Biomass fuel production facilities are complete sets of equipment that convert agricultural and forestry waste (such as sawdust, straw, reeds, etc.) into high-density, high-calorific-value fuels through physical or chemical methods. Their core objectives are to increase energy density, improve combustion performance, and achieve standardized production to replace fossil fuels.

[0003] In related technologies, reference can be made to Chinese utility model patent CN114250094B, which discloses a biomass fuel preparation device capable of producing fuel rods of equal length for easy transportation. This biomass fuel preparation device includes a conveying pipe, a pushing mechanism, a forming pipe, a mounting frame, and a cutting mechanism. The forming pipe is located at the rear end of the conveying pipe, and the mounting frame is fixed to the rear end of the forming pipe. The cutting mechanism for cutting the fuel is connected within the mounting frame, and the pushing mechanism is connected within the conveying pipe. An adding pipe is provided on the upper front end of the conveying pipe. The pushing mechanism includes a pushing shaft and a spiral plate; the pushing shaft rotates within the conveying pipe, and the spiral plate is fixed on the pushing shaft.

[0004] However, during actual operation, the aforementioned device generates a certain amount of debris when the fuel rod is cut, and some debris is also generated during the movement of the fuel rod when it is subsequently pushed. These debris can easily be scattered in the working environment as the fuel rod is discharged, causing pollution to the working environment and harming the health of the personnel who come to retrieve the fuel rod. Utility Model Content

[0005] To reduce the probability of fuel rod debris scattering in the working environment during discharge, this application provides a biomass fuel preparation apparatus.

[0006] This application provides a biomass fuel preparation device, which adopts the following technical solution:

[0007] A biomass fuel production apparatus includes a frame, on which a forming tube and a collection box are mounted. Fuel rods are formed inside the forming tube and then discharged into the collection box for collection. A guiding mechanism is provided on the frame to drive the fuel rods from the forming tube into the collection box. The guiding mechanism includes:

[0008] A guide plate is mounted on the frame. One end of the guide plate is connected to the forming tube, and the other end is connected to the collection box. A moving groove is provided on the guide plate, and the moving groove is connected to the inside of both the forming tube and the collection box.

[0009] Two conveyor wheels, both of which are mounted on a guide plate and located at opposite ends of the moving trough;

[0010] A conveyor belt, which is fitted onto two conveyor wheels;

[0011] A conveyor motor is mounted on a guide plate and its output shaft is connected to one of the two conveyor wheels.

[0012] A cover plate, which is rotatably mounted on a guide plate, and which blocks the opening of the movable slot;

[0013] A limiting component is disposed on the guide plate and is used to limit the rotational position of the cover plate;

[0014] A dust collection assembly, which is mounted on a frame and is used to absorb debris floating in the moving trough.

[0015] By adopting the above technical solution, a guide plate is installed between the forming tube and the collection box, and a conveyor belt is installed in the moving groove of the guide plate. The conveyor motor starts and drives the conveyor wheel to rotate, which in turn drives the conveyor belt to rotate. The rotation of the conveyor belt can move the fuel rods that have entered the moving groove, so that the fuel rods are guided from the forming tube into the collection box for collection. During the movement of the fuel rods, the cover plate is rotated to cover the moving groove, and the cover plate is limited by the limiting component. This can effectively prevent the probability of debris brought out by the fuel rods when they are removed from the forming tube from scattering in the working environment, and also reduce the probability of debris generated by the fuel rods during the movement scattering in the working environment.

[0016] Optionally, the limiting component includes:

[0017] A limiting spring is disposed on the guide plate;

[0018] A limiting block is horizontally slidably disposed on a guide plate in the direction of approaching or moving away from the cover plate and connected to a limiting spring. A limiting hole is provided on the side wall of the cover plate, and the limiting block is partially inserted into the limiting hole under the action of the limiting spring.

[0019] By adopting the above technical solution, a limiting spring and a limiting block are installed on the guide plate. When the cover plate covers the moving groove, the limiting block partially engages with the limiting hole under the action of the limiting spring, thereby limiting the position of the cover plate and reducing the probability of the cover plate opening due to mechanical vibration and causing debris to scatter.

[0020] Optionally, the guide plate is inclined, and the height of the end of the guide plate connected to the forming tube is higher than the height of the end connected to the collection box. The dust collection assembly includes:

[0021] The suction cup is vertically slidably mounted on the frame. The cover plate has a dust suction hole, which is blocked when the suction cup moves to its lowest position.

[0022] A movable component, which is mounted on the frame and is used to drive the suction cup to move;

[0023] A negative pressure fan, which is mounted on a frame;

[0024] The exhaust pipe has one end connected to a negative pressure fan and the other end connected to a suction cup. The exhaust pipe is connected to both the negative pressure fan and the inside of the suction cup. The exhaust pipe is configured as a flexible hose.

[0025] By adopting the above technical solution, when the cover plate covers the moving groove, the moving component starts to drive the suction cup to move until the suction cup touches the dust suction hole. Then, the negative pressure fan starts to suck air from the bottom of the cover plate through the exhaust pipe, so that the debris in the moving groove can be sucked into the exhaust pipe through the suction cup, thereby completing the work of sucking up the debris in the moving groove.

[0026] Optionally, the moving part includes:

[0027] A movable guide post is mounted on the frame, and the suction cup is slidably mounted on the movable guide post.

[0028] A movable electric cylinder is mounted on a frame, and the piston rod of the movable electric cylinder is vertically downward and connected to a suction cup.

[0029] By adopting the above technical solution, a movable guide post is installed on the frame, and the suction cup is vertically slid and installed through the movable guide post. A movable electric cylinder is installed on the frame, and when the movable electric cylinder is activated, it can drive the suction cup to move vertically along the movable guide post, thereby completing the work of controlling the vertical movement of the suction cup.

[0030] Optionally, the frame is provided with a filter mechanism for filtering debris extracted by the exhaust pipe, the filter mechanism comprising:

[0031] A filter clip frame is disposed between the negative pressure fan and the exhaust pipe;

[0032] A filter plate, wherein the filter plate is disposed within a filter debris frame;

[0033] A cleaning component is disposed on the filter debris frame and is used to clean the debris accumulated on the filter plate.

[0034] By adopting the above technical solution, a filter frame is installed between the negative pressure fan and the exhaust pipe, and a filter plate is installed inside the filter frame. The filter plate can filter the debris drawn by the exhaust pipe, thereby reducing the probability of debris entering the negative pressure fan and causing blockage. The cleaning component is used to clean the debris accumulated on the filter plate, which can ensure the filter plate's long-lasting filtering function.

[0035] Optionally, the cleaning component includes:

[0036] A cleaning plate, which is horizontally slidably disposed within the filter debris frame and in contact with the surface of the filter plate;

[0037] A push rod is horizontally slidably mounted on the filter chip frame, with one end of the push rod located outside the filter chip frame and the other end of the push rod extending into the filter chip frame and connecting to the cleaning plate;

[0038] A cleaning box is provided on the outer wall of the filter chip frame. A first through hole communicating with the inside of the filter chip frame is provided on the side wall of the cleaning box connected to the filter chip frame. A second through hole communicating with the first through hole is provided on the side wall of the filter chip frame located near the surface of the filter plate.

[0039] A baffle is vertically slidably disposed on the filter chip frame, and the baffle blocks the second through hole under the action of gravity.

[0040] By adopting the above technical solution, a cleaning plate is horizontally slidably installed inside the filter debris frame. Moving the push rod can drive the cleaning plate to move. The moving cleaning plate can scrape off the debris accumulated on the filter plate. Opening the baffle allows the cleaning plate to guide the debris through the first and second through holes into the collection box for collection, thereby completing the cleaning of the debris accumulated on the filter plate.

[0041] Optionally, a horizontal sliding hole is provided on the side wall of the cleaning box, and a collection frame is slidably installed on the cleaning box to receive debris falling out of the first through hole.

[0042] By adopting the above technical solution, horizontal sliding holes are opened on the cleaning box and a collection frame is installed, so that the debris can be taken out from the cleaning box for processing by moving the collection frame. The structure is simple and the operation is convenient and practical.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By installing a guide plate between the forming tube and the collection box, and then installing a conveyor belt in the moving groove of the guide plate, the conveyor motor starts to drive the conveyor wheel to rotate, the conveyor wheel rotates to drive the conveyor belt to rotate, and the rotation of the conveyor belt can move the fuel rods that have entered the moving groove, so that the fuel rods are guided from the forming tube to the collection box for collection. During the movement of the fuel rods, the cover plate is rotated to cover the moving groove, and the cover plate is limited by the limiting component, which can effectively prevent the probability of the debris brought out by the fuel rods when they are removed from the forming tube from flying into the working environment, and also reduce the probability of the debris generated by the fuel rods during the movement flying into the working environment;

[0045] 2. By installing a limiting spring and a limiting block on the guide plate, when the cover plate covers the moving groove, the limiting block partially engages with the limiting hole under the action of the limiting spring, thereby limiting the position of the cover plate and reducing the probability of the cover plate opening due to mechanical vibration and causing debris to scatter.

[0051] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0052] This application discloses a biomass fuel preparation apparatus.

[0053] Reference Figure 1 The biomass fuel production device includes a frame 1, on which a forming tube 11 and a collection box 12 are fixedly mounted. Fuel rods are formed inside the forming tube 11 and then discharged into the collection box 12 for collection. A guide mechanism 2 is provided on the frame 1 to drive the fuel rods from the forming tube 11 into the collection box 12.

[0054] Reference Figure 1 and Figure 2 The guiding mechanism 2 includes a guide plate 21, two conveyor wheels 22, a conveyor belt 23, a conveyor motor 24, a cover plate 25, a limiting component 26, and a dust collection component 27. The guide plate 21 is installed between the forming tube 11 and the collection box 12. One end of the guide plate 21 is fixedly connected to the outer side wall of the forming tube 11 near the collection box 12, and the other end of the guide plate 21 is fixedly connected to the outer side wall of the collection box 12 near the forming tube 11. The guide plate 21 is set in an inclined state, and the height of the end of the guide plate 21 connected to the forming tube 11 is higher than the height of the end connected to the collection box 12. A moving groove 28 is formed on the upper surface of the guide plate 21, and both ends of the moving groove 28 are connected to the interior of the forming tube 11 and the collection box 12.

[0055] Reference Figure 1 and Figure 2 Two conveyor wheels 22 are rotatably mounted on the inner wall of the moving trough 28 and located at opposite ends of the trough 28. A conveyor belt 23 is fitted onto the two conveyor wheels 22. A conveyor motor 24 is fixedly mounted on the guide plate 21, and its output shaft is connected to one of the two conveyor wheels 22. When the conveyor motor 24 starts, it drives the conveyor wheel 22 to rotate. The rotation of the conveyor wheel 22 drives the conveyor belt 23 to rotate, which in turn moves the fuel rods that have entered the moving trough 28, guiding them from the forming tube 11 into the collection box 12 for collection.

[0056] Reference Figure 2 The cover plate 25 is rotatably mounted on the upper surface of the guide plate 21. The cover plate 25 covers the upper opening of the moving groove 28. A limiting component 26 is disposed on the guide plate 21 and is used to limit the position of the cover plate 25 when it covers the moving groove 28. The limiting component 26 includes a limiting spring 31 and a limiting block 32. A mounting block 33 is fixedly mounted on the upper surface of the guide plate 21, and a sliding groove 34 is formed on the side wall of the mounting block 33 near the cover plate 25. The limiting spring 31 is fixedly mounted on the bottom wall of the sliding groove 34. The limiting block 32 is slidably mounted on the sliding groove 34 and connected to the limiting spring 31. A limiting hole is formed on the side wall of the cover plate 25 near the mounting block 33. Under the action of the limiting spring 31, the limiting block 32 partially engages with the limiting hole. This completes the limiting of the position of the cover plate 25.

[0057] Reference Figure 1 and Figure 2 A guide plate 21 is installed between the forming tube 11 and the collection box 12, and a conveyor belt 23 is installed in the moving groove 28 of the guide plate 21. The conveyor motor 24 starts, driving the conveyor wheel 22 to rotate. The rotation of the conveyor wheel 22 drives the conveyor belt 23 to rotate, which in turn moves the fuel rods that have entered the moving groove 28, guiding them from the forming tube 11 into the collection box 12 for collection. During the movement of the fuel rods, a rotating cover plate 25 covers the moving groove 28, and a limiting block 32 is used to limit the cover plate 25. This effectively prevents the probability of debris carried out by the fuel rods when they are removed from the forming tube 11 from scattering into the working environment, and also reduces the probability of debris generated by the fuel rods during movement scattering into the working environment.

[0058] Reference Figure 1 and Figure 2 A dust collection assembly 27 is mounted on the frame 1 and is used to absorb debris floating in the moving trough 28. The dust collection assembly 27 includes a suction cup 41, a moving part 42, a negative pressure fan 43, and an exhaust pipe 44. The suction cup 41 is vertically slidable on the frame 1 via the moving part 42. A dust collection hole is formed on the upper surface of the cover plate 25, penetrating vertically through the cover plate 25. When the suction cup 41 moves to its lowest position, it blocks the dust collection hole. The moving part 42 includes a moving guide post 45 and a moving electric cylinder 46. The moving guide post 45 is fixedly mounted on the frame 1 and is vertically arranged. The suction cup 41 is slidably mounted on the moving guide post 45. The moving electric cylinder 46 is fixedly mounted on the frame 1, and its output shaft is vertically downward and fixedly connected to the upper surface of the suction cup 41.

[0059] Reference Figure 1 and Figure 2 A negative pressure fan 43 is fixedly mounted on the frame 1. An exhaust pipe 44 is fixedly mounted between the suction cup 41 and the negative pressure fan 43. One end of the exhaust pipe 44 is connected to the negative pressure fan 43, and the other end is fixedly connected to the upper surface of the suction cup 41. The exhaust pipe 44, the negative pressure fan 43, and the suction cup 41 are all internally connected, and the exhaust pipe 44 is a flexible hose. When the negative pressure fan 43 is activated, it draws air through the exhaust pipe 44 to the bottom of the cover plate 25, allowing debris located in the moving groove 28 to be sucked into the exhaust pipe 44 through the suction cup 41, thus completing the removal of debris from the moving groove 28.

[0060] Reference Figure 2 and Figure 3The frame 1 is equipped with a filter mechanism 5 for filtering debris drawn by the exhaust duct 44. The filter mechanism 5 includes a filter frame 51, a filter plate 52, and a cleaning component 53. The filter frame 51 is fixedly installed between the negative pressure fan 43 and the exhaust duct 44, with both ends of the filter frame 51 connected to the negative pressure fan 43 and the exhaust duct 44, respectively. The filter plate 52 is fixedly installed on the inner wall of the filter frame 51. The filter plate 52 filters out the debris drawn into the exhaust duct 44 by the negative pressure fan 43 and places it on its surface. The cleaning component 53 is installed on the filter frame 51 and is used to clean the debris accumulated on the filter plate 52.

[0061] Reference Figure 2 and Figure 3 The cleaning assembly 53 includes a cleaning plate 54, a push rod 55, a cleaning box 56, and a baffle 57. The cleaning plate 54 is horizontally slidably installed inside the filter debris frame 51 and abuts against the surface of the filter plate 52. The push rod 55 is horizontally slidably installed on one outer wall of the filter debris frame 51. One end of the push rod 55 is located outside the filter debris frame 51, and the other end extends into the filter debris frame 51 and is fixedly connected to the cleaning plate 54. The cleaning box 56 is fixedly installed on the outer wall of the filter debris frame 51, and the cleaning box 56 and the push rod 55 are located on opposite side walls of the filter debris frame 51 in the horizontal direction. A first through hole communicating with the interior of the filter debris frame 51 is opened on the side wall of the cleaning box 56 connected to the filter debris frame 51, and a second through hole communicating with the first through hole is opened on the side wall of the filter debris frame 51 near the surface of the filter plate 52. The baffle 57 is vertically slidably installed on the upper surface of the filter debris frame 51, and the baffle 57 blocks the second through hole under the action of gravity.

[0062] Reference Figure 2 and Figure 3 When it is necessary to clean the debris accumulated on the surface of the cleaning plate 54, the movable baffle 57 opens the second through hole. The movable push rod 55 drives the cleaning plate 54 to move, and the movement of the cleaning plate 54 can scrape off the debris accumulated on the filter plate 52, and drive the debris through the first through hole and the second through hole into the collection box 12 for collection, thereby completing the cleaning work of the debris accumulated on the filter plate 52.

[0063] Reference Figure 3 A horizontal sliding hole is provided on the outer side wall of the cleaning box 56 away from the filter frame 51, and a collection frame 58 is horizontally slidably installed on the cleaning box 56. The collection frame 58 collects the debris falling from the first through hole. Thus, by moving the collection frame 58, the debris can be removed from the cleaning box 56 for processing. The structure is simple and the operation is convenient and practical.

[0064] The working principle of this application embodiment is as follows:

[0065] A guide plate 21 is installed between the forming tube 11 and the collection box 12, and a conveyor belt 23 is installed in the moving groove 28 of the guide plate 21. The conveyor motor 24 is started to drive the conveyor wheel 22 to rotate, which in turn drives the conveyor belt 23 to rotate. The rotation of the conveyor belt 23 moves the fuel rods that have entered the moving groove 28, so that the fuel rods are guided from the forming tube 11 into the collection box 12 for collection. During the movement of the fuel rods, the cover plate 25 is rotated to cover the moving groove 28, and the cover plate 25 is limited by the limiting block 32. This effectively prevents the probability of debris brought out by the fuel rods when they are removed from the forming tube 11 from scattering in the working environment, and also reduces the probability of debris generated by the fuel rods during the movement scattering in the working environment.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
