Description

Technical Field

[0001] The invention relates to the technical field of biomass fuels, and in particular to a pressing and forming device for making biomass fuels from solid waste. Background Art

[0002] Biomass fuel refers to the use of biomass materials as combustion fuel. The actual application is mainly biomass molded fuel. Biomass molded fuel uses agricultural and forestry waste as raw materials, such as straw, sawdust, bagasse and rice bran, which are made into granules or blocks through processes such as crushing, mixing, extrusion and drying. It is a clean fuel that can be directly burned. During the production and processing of biomass molded fuel, the raw materials will first be mixed, adjusted and crushed. In order for the biomass molded fuel to have better performance in production or use, shaping additives, combustion-aiding additives, etc. will be selectively added during the mixing and adjustment.

[0003] After searching, it was found that there are problems in the process of making biomass fuel from solid waste in the prior art. Since the staff generally loads the solid waste into the mold manually, the weight of the solid waste is not easy to control during the manual loading process, resulting in different volumes of biomass fuel blocks in the same batch. At the same time, after loading, the staff will have a hydraulic cylinder and a pressing plate to squeeze the solid waste. The stroke of the hydraulic cylinder will be limited by the volume of the solid waste in each groove on the mold, resulting in the pressing plate being difficult to press the solid waste in the mold into a suitable proportion, and its compression ratio is difficult to control, so that the volume compression ratio of the biomass fuel blocks after molding varies greatly, which is not conducive to the staff's batch and standardized production of biomass fuel blocks. Therefore, based on the above search and combined with the prior art, a pressing and molding device for making biomass fuel from solid waste is proposed to solve the above problems.

One end of the push plate 33 passes through the positioning groove 39 and is connected to one end of the air spring 28. An electric contact piece 45 is provided inside the positioning groove 39. An adjusting mechanism 8 for adjusting the position of the electric contact piece 45 is provided on one side of the mold 2.

[0035] The top surface of the cover plate 3 is provided with two connecting holes 24, which are connected to the forming groove 25. Two supporting frames 15 are fixedly installed on the top surface of the cover plate 3. A movable handle 47 is rotatably connected to one side of the supporting frame 15. A first DC motor 46 for driving the movable handle 47 to rotate is fixedly installed on one side of the supporting frame 15. One end of the output shaft of the first DC motor 46 passes through the supporting frame 15 and is fixedly connected to one side of the movable handle 47. A mounting block 48 is rotatably connected to one side of the movable handle 47. A supporting shaft 49 is fixedly installed on one side of the movable handle 47. The mounting block 48 is rotatably connected to the supporting shaft 49. An electric push rod 50 is fixedly installed on the bottom surface of the mounting block 48. The bottom of the telescopic shaft of the electric push rod 50 is fixedly connected to the bottom of the telescopic shaft of the electric push rod 50. A fixing frame 53 is fixedly installed on the surface, a second DC motor 54 is fixedly installed on the inner top surface of the fixing frame 53, a screw rod 55 is installed on the bottom surface of the output shaft of the second DC motor 54 through a coupling, a threaded sleeve 56 is threadedly connected to the outer circumferential wall surface of the screw rod 55, a plurality of connecting plates 57 are fixedly installed on the outer circumferential wall surface of the threaded sleeve 56, two movable rods 58 are rotatably connected between every two connecting plates 57 through pins, and clamping rods 63 are rotatably connected to the two movable rods 58 on both sides through pins, the clamping rods 63 are L-shaped structures, and a clamping plate 64 is fixedly installed on one side of the two clamping rods 63, the clamping plate 64 is a rectangular structure and the lower end is wavy, and the electric push rod 50 can adjust the position of the clamping plate 64;

[0036] One side of the interior of the fixed frame 53 is rotatably connected to two pull rods 60, and the pull rods 60 are rotatably connected to the movable rod 58 at the upper position through pins. Two rotating shafts 61 are fixedly installed on one side of the interior of the fixed frame 53, and the pull rods 60 are rotatably connected to the rotating shafts 61. The interior of the support frame 15 is slidably connected to the movable frame 51, and the outer circular wall surface of the electric push rod 50 is slidably connected to the movable frame 51. A slide bar 52 for limiting the movement of the movable frame 51 is fixedly installed inside the support frame 15, and the slide bar 52 is slidably connected to the movable frame 51. A slide groove matching the slide bar 52 is opened on one side of the movable frame 51, and both sides of the interior of the slide groove are inclined to the middle position of the slide groove. The rotation of the movable handle 47 drives the electric push rod 50 to move left and right. The left and right movement of the electric push rod 50 will drive the internal sliding of the movable frame 51 and make the movable frame 51 slide along the slide bar 52. The movable frame 51 and the slide bar 52 can limit the movement of the electric push rod 50.

[0037] A positioning hole 62 is provided on one side of the interior of the fixing frame 53, a placement block 59 is fixedly installed on the outer circumferential wall of the threaded sleeve 56, the placement block 59 is slidably connected with the positioning hole 62, the movement of the threaded sleeve 56 along the screw rod 55 will drive the placement block 59 to slide inside the positioning hole 62, the placement block 59 cooperates with the positioning hole 62 to limit the movement of the threaded sleeve 56, an alarm 65 for alarm is fixedly installed on the top surface of the substrate 1, a PLC controller is fixedly installed on the top surface of the substrate 1, and the conveyor belt body 7, the first hydraulic cylinder 10, the scale body 13, the electric contact sheet 45, the second DC motor 54, the electric push rod 50 and the first DC motor 46 are all electrically connected to the PLC controller;

[0038] Solid waste refers to straw, sawdust, bagasse and rice bran, etc. These materials are mixed, adjusted and crushed before being used as raw materials;

[0039] Through the above technical features, through the provided conveyor belt body 7, the staff pours the solid waste onto the two conveyor belt bodies 7, so that the solid waste is transported upward along the conveyor belt body 7 and falls into the inside of the feed hopper 4, and the solid waste entering the inside of the feed hopper 4 will fall on the top surface of the scale body 13 on the baffle 12, and the scale body 13 can weigh the solid waste. Under normal circumstances, when the solid waste reaches the weight set by the staff, the two baffles 12 drive the scale body 13 to move inward inside the limiting hole 19 on the cover plate 3, and after the baffles 12 and the scale body 13 move inward, the solid waste inside the feed hopper 4 will enter the inside of the forming groove 25, and then the two baffles 12 are reset to continue to block the solid waste (in the process of resetting the two baffles 12, some solid waste may enter the forming groove 25 in the gap of the baffle 12 reset, which is an unexpected situation);

[0040] The staff starts the first hydraulic cylinder 10, and the telescopic shaft of the first hydraulic cylinder 10 moves inward to drive the pressing plate 11 to move inward inside the forming groove 25 to squeeze the solid waste. The squeezing causes the solid waste to push the push plate 33 to move backward. The push plate 33 moves backward to drive the connecting rod 34 to move backward. The connecting rod 34 moves backward to compress the air spring 28. The reaction force of the air spring 28 causes the push plate 33 and the connecting rod 34 to cooperate with the pressing plate 11 to squeeze both sides of the solid waste.

[0041] As the telescopic shaft of the first hydraulic cylinder 10 continues to move forward, the solid waste and the connecting rod 34 will continue to move backward until they contact the electric contact piece 45 in the positioning groove 39. At this time, the electric contact piece 45 will transmit a signal to the PLC controller, and the PLC controller will allow the first hydraulic cylinder 10 to drive the pressing plate 11 to reset. In this process, the weight of the solid waste used to make biomass fuel each time is the same, and the moving distance of the pressing plate 11 and the connecting rod 34 is the same, so that the biomass fuel blocks made each time have a similar compression ratio, and then the volume of the biomass fuel blocks is the same, and the degree of standardization is high;

[0042] When an unexpected situation occurs, if a large amount of solid waste is put in, the telescopic shaft of the first hydraulic cylinder 10 drives the pressure plate 11 to push the solid waste and the push plate 33 to move backward. At this time, the push plate 33 cannot contact the positioning block 29. The staff starts the first DC motor 46. The output shaft of the first DC motor 46 rotates forward and reversely to drive the movable handle 47 to rotate back and forth. When the output shaft of the first DC motor 46 rotates forward to drive the electric push rod 50 to move downward, the electric push rod 50 moves downward inside the movable frame 51, and at the same time, the movable frame 51 moves inward along the slide bar 52. The electric push rod 50 moves downward to drive the fixed frame 5 3 moves downward, the fixing frame 53 moves downward through the connecting hole 24 and enters the interior of the forming groove 25. At this time, the output shaft of the second DC motor 54 rotates forward to drive the screw rod 55 to rotate, and the screw rod 55 rotates to drive the threaded sleeve 56 to move upward along the screw rod 55. The threaded sleeve 56 moves upward to drive the left ends of the multiple movable rods 58 to rotate upward between the two groups of connecting plates 57 through the pins. The left end of the movable rod 58 rotates upward so that the right end of the movable rod 58 drives the clamping rod 63 and the clamping plate 64 to rotate downward through the pins and clamp. The clamping rod 63 and the clamping plate 64 can clamp the solid waste between the pressing plate 11 and the clamping plate 64;

[0043] Then, the driving shaft of the first DC motor 46 rotates in the reverse direction to drive the electric push rod 50 to move downward inside the movable frame 51, and at the same time, the electric push rod 50 and the fixed frame 53 drive the movable frame 51 to move outward on the slide bar 52 to the outside of the mold 2. At this time, the driving shaft of the second DC motor 54 rotates in the reverse direction to drive the screw rod 55 to rotate in the reverse direction. The screw rod 55 rotates in the direction to reset the threaded sleeve 56 and separate the two clamping plates 64. The separation of the two clamping plates 64 causes the solid waste clamped between the two clamping plates 64 to fall outside the mold 2. The staff allows the two clamping plates 64 to continuously clamp the excess solid waste inside the molding groove 25. The waste electric push rod 50 will also continuously lower the height of the two clamping plates 64, so as to remove the excess solid waste in the forming groove 25. In this process, the telescopic shaft of the first hydraulic cylinder 10 continuously drives the pressing plate 11 to move forward to squeeze the solid waste. As the solid waste decreases, the pressing plate 11 pushes the solid waste and the connecting rod 34 to move backward until they contact the electric contact sheet 45. At this time, the compression molding of the solid waste is completed. Even if an unexpected situation occurs, the compression ratio of the biomass fuel block can be guaranteed, and the standardization of the production of the biomass fuel block is further maintained, so as to achieve the compression molding effect of the solid waste, and facilitate the subsequent use of the biomass fuel block by the staff;

[0044] The inner part of the limiting hole 19 is rotatably connected with a gear 21, and a driving motor 14 for driving the gear 21 to rotate is fixedly installed on the top surface of the substrate 1, and the output shaft of the driving motor 14 is fixedly connected with the bottom surface of the gear 21, and the outer circumferential wall surface of the gear 21 is meshedly connected with two racks 22, and one side of the rack 22 is fixedly connected with one side of the baffle 12, and the driving motor 14 is electrically connected with the PLC controller;

[0045] Specifically, through the set feed hopper 4, solid waste falls onto the scale body 13 on the baffle 12 through the feed hopper 4. When the weight of the solid waste reaches the preset weight of the staff, the PLC controller will start the drive motor 14. The output shaft of the drive motor 14 rotates to drive the gear 21 to rotate. The rotation of the gear 21 drives the two racks 22 to move inward. The inward movement of the rack 22 drives the two groups of baffles 12 and the scale body 13 to move inward. After the baffle 12 and the scale body 13 are no longer blocked, the solid waste of the predetermined weight can enter the interior of the molding groove 25 on the mold 2, thereby achieving the feeding effect of the solid waste.

[0046] As a preferred implementation in this embodiment, please refer to Figure 1 - Fig. 9 A support groove 20 is provided on one side of the inner side of the limiting hole 19, a connecting block 23 is fixedly installed on one side of the rack 22, and the connecting block 23 is slidably connected to the support groove 20, and positioning blocks 29 are fixedly installed on both sides of the baffle 12, and the positioning blocks 29 are slidably connected to the support groove 20;

[0047] Specifically, by means of the rack 22, the rack 22 moves to drive the connecting block 23 to slide inside the supporting groove 20 inside the limiting hole 19, and the connecting block 23 can limit the movement of the rack 22. The movement of the baffle 12 inside the limiting hole 19 drives the positioning block 29 to move inside the supporting groove 20, and the positioning block 29 can limit the movement of the baffle 12, thereby improving the stability of the movement of the baffle 12.

[0048] The top surface of the mold 2 is provided with a mounting groove 30, which is connected to the molding groove 25. A discharge plate 32 for pushing the biomass fuel to move is slidably connected inside the mounting groove 30. A second hydraulic cylinder 31 for driving the discharge plate 32 to move is inside the mounting groove 30. The second hydraulic cylinder 31 is electrically connected to the PLC controller.

[0049] Specifically, the second hydraulic cylinder 31 and the second hydraulic cylinder 32 move forward to drive the pressed biomass fuel block to move outward along the transverse forming groove 25 to the outside of the mold 2, thereby pushing the formed biomass fuel block to the outside of the mold 2, thereby achieving the discharge effect of the biomass fuel block;

[0050] The adjustment mechanism 8 includes two knobs 26, which are respectively installed on one side of the two molds 2. A fixing block 40 is fixedly installed inside the positioning groove 39. A threaded rod 41 is threadedly connected to one side of the fixing block 40. One end of the threaded rod 41 is connected to the electric contact piece 45 through a bearing. A first conical tooth 42 is fixedly installed on the other end of the threaded rod 41. The outer circumferential wall surface of the first conical tooth 42 is meshedly connected with a second conical tooth 44. A mounting rod 43 is fixedly installed on one end of the second conical tooth 44. One end of the mounting rod 43 passes through the positioning groove 39 and extends to the outside of the mold 2. One end of the mounting rod 43 is fixedly connected to one end of the knob 26.

[0051] Specifically, through the knob 26, the staff turns the knob 26 to drive the installation rod 43 to rotate, the installation rod 43 rotates to drive the second conical teeth 44 to rotate, the second conical teeth 44 rotate to drive the first conical teeth 42 to rotate, the first conical teeth 42 rotate to drive the threaded rod 41 to rotate, the threaded rod 41 rotates to drive the inner ring of the bearing to rotate and move the electric contact piece 45 at the same time, the staff can move the position of the electric contact piece 45 forward or backward by turning the knob 26, so as to adjust the compression ratio of the biomass fuel block;

[0052] Two support holes 17 are provided on the top surface of the base plate 1. Several electric rollers 18 for conveying biomass fuel blocks are rotatably connected inside the support holes 17. Connecting rollers 38 are fixedly installed at both ends of the electric rollers 18. One end of the connecting roller 38 is rotatably connected to one side of the inside of the support hole 17 through a bearing. Several limiting plates 16 for limiting biomass fuel blocks are fixedly installed on the top surface of the base plate 1.

[0053] Specifically, through the setting of the mold 2, the biomass fuel formed inside the mold 2 will be moved to multiple electric rollers 18. The rotation of the electric rollers 18 drives the positioning grooves 39 and the inner rings of the bearings to rotate. The multiple electric rollers 18 can continue to transport the biomass fuel forward. During this process, the limiting plate 16 can limit the two sides of the biomass fuel block to achieve the transportation effect of the biomass fuel block.

[0054] The collecting mechanism 9 includes two limiting frames 36, both of which are fixedly mounted on the bottom surface of the base plate 1, the inside of the limiting frames 36 is slidably connected with the collecting box 35, and the inner bottom surface of the limiting frames 36 is fixedly mounted with a magnet 37 for limiting the collecting box 35;

[0055] Specifically, through the provided clamping plates 64, the solid waste clamped by the two clamping plates 64 will fall onto multiple electric rollers 18, and the solid waste will enter the interior of the collection box 35 through the gap between the electric rollers 18 and the support holes 17. The magnet 37 inside the limiting frame 36 can limit the position of the collection box 35. The staff will move the collection box 35 to the interior of the limiting frame 36 and take out the solid waste therein for utilization, thereby preventing the solid waste from being scattered on the ground.

[0056] Working principle: through the conveyor body 7, the staff pours the solid waste on the conveyor body 7, and the conveyor body 7 transports the solid waste upward. When the conveyor body 7 transports the solid waste to the top, the solid waste will fall into the inside of the feed hopper 4. The solid waste entering the inside of the feed hopper 4 will fall on the scale body 13 on the top surface of the baffle 12. When the solid waste on the scale body 13 reaches a preset weight, the two baffles 12 move inward to allow the solid waste to enter the inside of the molding groove 25 on the mold 2;

[0057] Secondly, the staff starts the first hydraulic cylinder 10. The telescopic shaft of the first hydraulic cylinder 10 moves inwards, driving the pressure plate 11 to move inwards and cooperate with the push plate 33 to squeeze the solid waste. The pressure plate 11 drives the solid waste and the push plate 33 to move backwards until they contact the positioning groove 39. After the push plate 33 contacts the electric contact sheet 45, the second hydraulic cylinder 31 moves to drive the discharge plate 32 to move outwards. The discharge plate 32 moves outwards to move the biomass fuel block to the outside of the forming groove 25.

[0058] At the same time, if the solid waste entering the molding groove 25 exceeds the standard, the staff starts the first DC motor 46, and the driving shaft of the first DC motor 46 rotates to drive the movable handle 47 to move back and forth, and the movable handle 47 moves back and forth to drive the electric push rod 50 and the fixed frame 53 to move back and forth. The two clamping plates 64 inside the fixed frame 53 can clamp the excess solid waste inside the molding groove 25 through the connecting hole 24 and move the solid waste to the outside of the mold 2. As the solid waste decreases, the connecting rod 34 moves under the push of the pressing plate 11 until it contacts the positioning groove 39, thereby ensuring the compression ratio of the biomass fuel block and achieving a standard block of the biomass fuel block;

[0059] Finally, the formed biomass fuel blocks are transported outwards through a plurality of electric rollers 18 to prevent the formed biomass fuel blocks from piling up on the top surface of the base plate 1 .

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
