Description

Technical Field

[0002] According to the forecast of agricultural and forestry development needs, my country's biomass resources can reach a production capacity potential of about 610 million tons of standard coal. The application of biomass to gradually replace fossil fuels can effectively reduce the dependence of traditional production processes on non-renewable resources, reduce greenhouse gas emissions in the production process, and simultaneously achieve the reduction and resource utilization of agricultural and forestry solid waste.

[0003] In the prior art, biomass is dried and crushed to make biomass raw material particles. Biomass raw material particles usually have high water content, poor grindability, low energy density, easy corruption and other problems, and are usually difficult to use directly; baking pretreatment is an effective means to optimize the quality of biomass fuel, which can significantly improve the energy density, thermal stability and grindability of biomass raw material particles.

[0004] The baking process in the prior art is to place biomass particles in a stacked bed reaction device, pass the treated high-temperature flue gas from the boiler to dry them, and cool and store the improved samples through a water cooling system to obtain a baked pretreated biomass fuel. However, the biomass raw material particles placed at the bottom and inside are not in direct contact with the boiler flue gas, and the drying efficiency is low, resulting in different drying effects inside and outside, affecting the quality of the finished product.

At the same time, the winding part rolls up the flattened biomass particles into the drying chamber to achieve layered storage of the biomass particles. After the layered storage is completed, each group of air inlet pipes and air outlet pipes are arranged at the corresponding end of the drying chamber, which is convenient for the subsequent positioning and transportation of boiler flue gas, replacing the traditional stacking drying method, improving the drying efficiency, and allowing the biomass particles inside and outside to be dried synchronously, thereby improving the quality of the biomass fuel.

[0039] Working principle of the first embodiment:

[0040] The unloading part 8 is controlled to drive the winding part 7 to slide synchronously. During this process, the unloading part 8 evenly lays the biomass particles on the drying section 14.

[0043] The inner wall of the fixed box 1 is symmetrically provided with slide grooves 35; the sliding part includes a guide plate 36 symmetrically slidably arranged in the corresponding slide grooves 35; a slide rod 37 is symmetrically fixed between the two guide plates 36; a screw rod 38 is rotatably arranged between the two guide plates 36; a servo motor 39 is fixedly installed on the side of one guide plate 36; the output end of the servo motor 39 is fixedly connected to one end of the screw rod 38; a screw hole 40 that is rotatably matched with the screw rod 38 is provided on the side of the U-shaped frame 28; sliding holes 41 that are slidably matched with the slide rod 37 are symmetrically provided on the side of the U-shaped frame 28; a bearing plate 42 with a hollow interior is fixed to the inner wall of the fixed box 1; a plurality of adsorption holes 43 are evenly provided on the top of the bearing plate 42; an L-shaped tube 44 that passes through the inner wall of the fixed box 1 and extends outward is connected to the bottom surface of the bearing plate 42; the L-shaped tube 44 is connected to an external vacuum pump through an exhaust hose.

[0044] Extension plates 45 are symmetrically fixed to the sides of the U-shaped frame 28; a storage box 46 is fixed between the two extension plates 45; the inner bottom surface of the storage box 46 is opened, and a feed roller 47 is rotatably arranged between its inner walls near its bottom; a number of discharge grooves 48 are evenly arranged on the sides of the feed roller 47; a drive motor 79 electrically connected to the output end of the controller 4 is fixed to the side of the storage box 46; the output end of the drive motor 79 is fixedly connected to one end of the feed roller 47.

[0045] Working principle of the second embodiment:

[0046] In the initial state, both ends of the first winding shaft 9 are respectively placed at the bottom of the corresponding inclined guide groove 2. At this time, the baffle 20 is inserted into the two insertion grooves 24 to achieve fixed limiting of the connecting section 16 on the high temperature resistant conveyor belt 11. At this time, the drying section 14 and the sealing section 15 on the high temperature resistant conveyor belt 11 are flatly laid on the supporting plate 42.

[0047] The external vacuum pump is controlled to start to extract the air inside the carrier plate 42 through the L-shaped tube 44, so that a negative pressure environment is formed inside the carrier plate 42, and the high temperature resistant conveyor belt 11 is sucked through the adsorption hole 43. The servo motor 39 is controlled to start to drive the screw rod 38 to rotate, thereby driving the unloading part 8 to slide along the slide rod 37 toward the direction close to the discharge port 75. In this process, the first winding roller 9 on the winding part 7 is driven to slide and rise along the inclined guide groove 2, and the first gear 6 at the end of the first winding roller 9 is meshed and rotated along the corresponding first tooth plate 3 to advance, thereby realizing the winding of the high temperature resistant conveyor belt 11. During the winding process of the high-temperature resistant conveyor belt 11, the high-temperature resistant rubber strip 12 thereon is stuck into the sealing groove 13 at the corresponding position. When the first winding roller 9 moves and presses on the end at the highest point of the inclined guide groove 2, the high-temperature resistant conveyor belt 11 has just completed winding, and the sealing section 15 is wound on the outer peripheral side, cooperating with each group of wound high-temperature resistant rubber strips 12 to achieve sealing of both ends of each group of drying chambers 22, so that the biomass particles stored in each group of drying chambers 22 are in a sealed environment. At this time, the high-temperature resistant rubber strips 12 corresponding to the ends of each group of drying chambers 22 are alternately arranged with inlet pipes 18 and outlet pipes 19 in sequence.

[0048] During the movement of the unloading part 8, the driving motor 79 is controlled to start and drive the unloading roller 47 to rotate, and the discharging trough 48 placed inside the storage box 46 rotates to be separated from the storage box 46, and the biomass particles in the discharging trough 48 fall onto the surface of the drying section 14. As the unloading part 8 slides, the first winding roller 9 on the winding part 7 winds up the drying section 14, and is adsorbed on the surface of the drying section 14 through the air vents 17 to prevent the biomass particles from falling off due to gravity during the winding process, affecting the winding and storage, so that the corresponding biomass particles are stored in the corresponding drying chamber 22; when the drying sections 14 are all wound up, the driving motor 79 is controlled to stop, the unloading of the biomass particles is stopped, and the unloading part 8 continues to slide to realize the winding of the sealing section 15.

[0049] In summary, through the linkage and coordination between various components, the automatic unloading, automatic winding and layered storage of biomass particles can be achieved, thereby improving work efficiency.

[0050] For example 3, please refer to Figure 1-13, the third embodiment of the present invention is improved as follows on the basis of the second embodiment. Specifically, a plurality of sliding sleeves 49 are slidably arranged on the sliding rod 37; an ear rod 50 is fixed to the side surface of the sliding sleeve 49; a connector 51 is fixed to the end of the ear rod 50; a first delivery pipe 52, a second delivery pipe 53, a third delivery pipe 54 and a fourth delivery pipe 55 are sequentially penetrated and connected to the inner wall of the fixed box 1; the ends of the first delivery pipe 52, the second delivery pipe 53, the third delivery pipe 54 and the fourth delivery pipe 55 are all connected and provided with a gas delivery hose 56; the gas delivery hose 56 is fixed on the corresponding sliding sleeve 49 and the connector 51; the first delivery pipe 52, the second delivery pipe 53, the third delivery pipe 54 and the fourth delivery pipe 55 are all provided with a gas delivery hose 56 connected to the controller 4 The outlet end is electrically connected to a solenoid valve; the first delivery pipe 52 and the third delivery pipe 54 are connected to the boiler exhaust pipe, and the flue gas in the boiler exhaust pipe is connected to the first delivery pipe 52 and the third delivery pipe 54 after being cooled and filtered to prevent the high-temperature flue gas from being too hot and affecting its use; the second delivery pipe 53 and the fourth delivery pipe 55 are connected to the external gas pipe; the end of the gas hose 56 is connected to a gas collecting box 57; a number of ear tubes 58 are evenly connected to the side of the gas collecting box 57; the ear tubes 58 respectively connected to the first delivery pipe 52, the second delivery pipe 53, the third delivery pipe 54 and the fourth delivery pipe 55 are respectively connected to the air inlet pipe 18 and the air outlet pipe 19 at both ends of the high-temperature resistant conveyor belt 11 through high-temperature resistant hoses.

[0051] A return spring 59 is fixedly connected between one end of the guide plate 36 and the slide groove 35, and a guide rod 60 is fixed at the other end thereof and is slidably arranged through the fixed box 1; a fixed plate 61 is fixed between the two guide rods 60; an iron block 62 is fixed to the side of the fixed plate 61; a U-shaped plate 63 is fixed to the side of the fixed box 1; an electromagnetic suction cup 64 electrically connected to the output end of the controller 4 is fixed to the inner wall of the U-shaped plate 63; the output end of the controller 4 is electrically connected to the electromagnetic suction cup 64 and the external vacuum pump respectively.

[0052] Working principle of the third embodiment:

[0053] During the sliding process of the unloading part 8, the winding part 7 is driven to move synchronously. In this process, each group of gas collecting boxes 57 and the corresponding gas delivery hose 56 are driven to move synchronously. When the biomass particles are layered and rolled up, the solenoid valve on the first conveying pipe 52 is controlled to open, and the solenoid valve on the fourth conveying pipe 55 is opened at the same time. At this time, the solenoid valves on the second conveying pipe 53 and the fourth conveying pipe 55 are closed, and the boiler exhaust pipe connected to the first conveying pipe 52 sends the treated high-temperature flue gas through the first conveying pipe 52 into the corresponding gas delivery hose 56, and passes through the corresponding gas collecting box 57. The flue gas is sent into the corresponding drying chamber 22 through the ear tubes 58 and the corresponding air inlet pipes 18 on the corresponding drying chamber 22 to dry the biomass particles in the drying chamber 22, and the flue gas after heat exchange is discharged through the corresponding air outlet pipe 19, the corresponding air delivery hose 56, and the fourth delivery pipe 55; after a period of time, the solenoid valves on the first delivery pipe 52 and the fourth delivery pipe 55 are controlled to be closed, and the solenoid valves on the second delivery pipe 53 and the fourth delivery pipe 55 are opened at the same time, and the high-temperature flue gas in the boiler exhaust pipe enters through the other end to dry the biomass particles in each group of drying chambers 22.

[0054] In summary, by controlling the periodic opening and closing of the corresponding solenoid valves, the boiler high-temperature flue gas can periodically enter alternately from both ends of the combined drying chamber 22, thereby drying the biomass particles in each group of drying chambers 22, thereby improving the drying efficiency and drying effect.

[0055] After completing the layered storage, the arc sleeve 32 moves to be sleeved in the second annular groove 33 (the arc sleeve 32 can also be set as a straight plate, the size of which is compatible with the second annular groove 33, that is, it can be inserted between the inner walls of the second annular groove 33 to drive the second winding roller 10 along its length direction). When the electromagnetic suction cup 64 is energized, it attracts the iron block 62, pulling the sliding part toward the direction close to the electromagnetic suction cup 64, and the corresponding reset spring 59 is stretched. When the electromagnetic suction cup 64 loses power, under the elastic reset force of the reset spring 59, the sliding part is driven to slide in the direction away from the electromagnetic suction cup 64, and the electromagnetic suction cup 64 is controlled to periodically gain and lose power, so that the sliding part drives the second rotating shaft 26 on the winding part 7 to slide back and forth along the shaft hole 25, and drives the first rotating shaft 27 to slide back and forth along the inclined guide groove 2, so as to realize the periodic sliding of the biological clock particles inside each group of drying chambers 22, thereby further improving the drying efficiency.

[0058] Working principle of the fourth embodiment:

[0059] When the unloading part 8 and the winding part 7 are moving, the brake structure in the brake motor 5 clamps and fixes its output end, so that the first gear 6 remains stationary, thereby limiting the first tooth plate 3. During this process, the first tooth plate 3 remains stationary, and the third gear 82 at the end of the first rotating shaft 27 rotates and moves forward along the first tooth plate 3 to achieve winding.

[0060] When the biomass particles are dried, the electric push rod 66 is controlled to start and shrink, so that the baffle 20 is pulled out from the corresponding plug-in slot 24, and the fixing restriction on the connecting section 16 on the high temperature resistant conveyor belt 11 is released. Figure 5As shown, the control brake motor 5 is started, driving the first gear 6 to rotate clockwise, thereby driving the first tooth plate 3 to slide and rise along the inclined groove 67 (slide in the direction close to the controller 4), thereby driving the third gear 82 placed above the first tooth plate 3 and meshing with the first tooth plate 3 to rotate counterclockwise, thereby realizing the release of the high-temperature resistant conveyor belt 11 by the first winding roller 9, and driving the corresponding sprocket 73 to rotate clockwise through the chain 74, thereby driving the second tooth plate 69 to slide in the opposite direction along the straight groove 68 (slide in the direction away from the controller 4), thereby driving the fourth gear 83 placed above the second tooth plate 69 and meshing with the second tooth plate 69 to rotate clockwise, thereby realizing the synchronous winding of the high-temperature resistant conveyor belt 11 by the second winding roller 10. In this process, the dried biomass particles detach from the corresponding drying chamber 22 and fall into the discharge port 75 to be collected, so as to facilitate the collection of the dried biological clock particles.

[0061] After the collection is completed, the brake motor 5 is controlled to start, driving the first gear 6 to rotate counterclockwise, thereby driving the second winding roller 10 to release the high-temperature resistant conveyor belt 11, and driving the first winding roller 9 to synchronously wind up the high-temperature resistant conveyor belt 11, and controlling the start of the electric push rod 66 to extend it to drive the baffle 20 to be inserted into the corresponding plug-in slot 24, so as to achieve fixed restriction on the connecting section 16, and controlling the servo motor 39 to drive the screw rod 38 to rotate in the opposite direction. Under the elastic force of the extrusion spring, the wound high-temperature resistant conveyor belt 11 is flatly laid on the surface of the carrying plate 42 during the reverse movement and release process, and each group of air inlet pipes 18 and air outlet pipes 19 on the high-temperature resistant conveyor belt 11 after flattening are coaxially arranged with the corresponding positioning holes 78. The sealing cover 80 is regularly disassembled for cleaning, so as to facilitate the dredging of each group of coaxial air inlet pipes 18 and air outlet pipes 19 through the dredging rod, thereby improving the practicality of the device.
