Description

Technical Field

[0001] This utility model relates to the technical field of material processing, specifically to an energy-saving fluidized bed furnace. Background Technology

[0002] In the porcelain manufacturing process, a fluidized bed furnace is usually used to fire some of the materials to reduce the moisture content and promote crystal formation. Traditional fluidized bed furnaces typically use a single-layer air blowing system, which requires controlling the airflow. The hot air is then recycled after passing through the baking layer, resulting in significant energy waste. When multiple layers are stacked, the airflow to the bottom baking layer is too high, causing the material to flow directly out through the air outlet, while the top baking layer fails to achieve the desired firing effect. This leads to uneven overall temperature, making the material unusable and causing deviations in the quality of the materials from the same furnace. This severely affects the shape and structure of porcelain products from the same batch, rendering them unusable. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an energy-saving fluidized bed oven with better thermal energy utilization efficiency, while realizing multi-level and multi-layer baking without the need to control the air volume.

The rotating rods are disposed in the area of ​​the vertical air guide plate away from the support plane, and the rotating rods are connected to and rotatably connected to the inner frame of the flow equalization frame.

[0009] In one embodiment, a bracelet-shaped ring is provided on the inner cavity side of the protruding ring. The bracelet-shaped ring has a semi-circular rotating structure, and a plurality of fixed fins are provided between the bracelet-shaped ring and the protruding ring.

[0010] In one embodiment, the rectangular tube is provided with a plurality of air guide baffles, which are evenly arranged in an inclined array on both sides of the inner cavity of the rectangular tube with a tendency to move away from the perforated plate. The adjacent air guide baffles overlap in the vertical projection of the plane of the perforated plate. The inner cavity of the rectangular tube is also provided with a ventilation baffle, which is placed in the opposite direction to the air guide baffles and abuts against the three sides of the inner cavity of the rectangular tube. The ventilation baffle is located at the end of the plurality of air guide baffles away from the perforated plate.

[0011] In one embodiment, the rectangular tube is provided with an inlet pipe and an outlet pipe on both sides of the contact surface of the air guide baffle. The inlet pipe and the outlet pipe pass through the rectangular tube. The connection ports of the inlet pipe and the outlet pipe are located on both sides of the cavity between the plurality of air guide baffles and the perforated plate. A rotating block is provided at one end of the inlet pipe and the outlet pipe near the rectangular tube. The rotating block is provided with an air vent. A feed inlet is provided in the middle of the inlet pipe. An outlet pipe is provided at one end away from the rectangular tube. A rotating shaft is provided on the central axis of the inlet pipe and the outlet pipe. The outlet pipe and the outlet pipe are also provided with a drive motor. The drive motor drives the adjacent rotating shaft to rotate. A rotating block is provided at one end of the rotating shaft near the rectangular tube. Two adjacent sets of rotating blocks abut against each other.

[0012] The beneficial effects of this utility model are as follows: This utility model is an energy-saving fluidized bed oven with good thermal energy utilization efficiency, which can realize multi-stage and multi-layer baking without the need to control the air volume. The specific implementation method is as follows: The operator first feeds the calcining material through the inlet into the feed pipe. Then, the drive motor is started to rotate the rotating shaft and open the ventilation gaps on the two sets of rotating blocks. This allows the material in the feed pipe to flow into the perforated plate through the rectangular tube. The rotating blocks are then rotated to make the two sets of ventilation gaps cross and stagger to form a sealing structure, and the calcination work can then begin. After hot air is delivered from the heating furnace, the blower is started and the air is introduced into the air inlet funnel through the air supply pipeline. A large volume of hot air first passes through the gaps in the vertical air guide plates on the nearest flow equalization frame, and then blows the material through the perforated plate for baking. However, because the rectangular tubes are designed in a three-dimensional, multi-layered manner, the wind speed and intensity of the rectangular tubes closer to the air inlet funnel are greater than those above. Therefore, it is necessary to reduce the wind speed at the bottom and increase the wind speed at the top: Adjust the relative height of the magnetic semi-guide strips and the vertical air guide plates. The closer the magnetic semi-guide strips on the vertical air guide plates near the lower air inlet funnel are to the air inlet funnel, the more airflow there will be. After a large volume of air passes through the magnetic semi-guide strips between the two sets of vertical air guide plates, the air flow causes the ends of the two sets of vertical air guide plates furthest from the rotation axis to meet. As the airflow approaches each other, areas with high air volume are affected by the gaps between them, resulting in reduced inflow and air volume. The vertical air guide plates, which are further away from the air inlet funnel, are higher due to the height of the magnetic semi-guide strips. After the gas flows into the two sets of vertical air guide plates, it first passes through the straight area of ​​the vertical air guide plates, and then passes between the magnetic semi-guide strips. Because the magnetic semi-guide strips are close to the rotating rod, the rotational force is greater, causing the vertical air guide plates to not rotate. The smaller gaps increase the permeability pressure and provide greater energy, making it easier to blow more powerful air onto the upper rectangular tubes. At the same time, the two vertically set layers of air guide plates can evenly divide the air, ensuring that the airflow in each area remains as uniform as possible. After passing through the perforated plate, the air flows into the rectangular tube, achieving roasting.

[0013] Meanwhile, even if the airflow below the perforated plate is controlled, excessive airflow can still cause the roasting material to fly out of the rectangular tube. To solve this problem, a stepped baffle is used to diagonally guide the strong airflow. During the diagonal flow of the airflow below, it will also obstruct the airflow at the same position. Finally, the airflow is guided to the other side of the baffle away from the perforated plate through the ventilation baffle. The airflow intensity is greatly reduced, and the roasting material is carried away from the other side of the baffle away from the perforated plate and falls into the perforated plate, preventing the material from flowing out. Meanwhile, due to the gap between the extension tube and the rectangular tube, the gas flows directly through the gap to the exhaust pipe above the top cover bowl. This results in the rectangular tubes, except for the bottom rectangular tube, not being able to be blown by the airflow. In order to adjust the gas flow direction, a bracelet-shaped ring is set between the protruding rings, so that there is an arc-shaped channel between them. When the gas flows in the gap, it first passes through one end of the arc-shaped groove and is then blown into the bottom of the rectangular tube by the guiding action of the arc-shaped groove. This allows the hot air below to continue to enter the middle rectangular tube, thus achieving the roasting of the rectangular tube.

[0014] After roasting, the drive motor on the discharge pipe continues to rotate, connecting the two sets of rotating blocks on the discharge pipe. Hot air carries the roasted particles through the air guide baffle and the space below the perforated plate, then continues to flow out through the long discharge pipe for further collection, thus achieving the purpose of material collection. This equipment has a simple structure and effectively utilizes a special air guide structure to solve the problems of high-altitude hot air delivery and material entrainment during large-volume airflow. It effectively achieves efficient use of hot air, saves energy, and has good practicality and economy, which is beneficial for the promotion and use of the equipment. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] The following is combined with Figure 1-9This invention describes a specific embodiment of an energy-saving fluidized bed boiler, comprising a heating furnace 1. A fluidized bed mechanism 3 is provided on one side of the heating furnace 1. The heating furnace 1 uses a blower 2 to introduce hot air from a gas supply pipe 21 into the fluidized bed mechanism 3. The fluidized bed mechanism 3 includes a vent hood with a capsule-shaped structure. The gas supply pipe 21 enters the vent hood. Specifically, the vent hood includes several extension pipes 31, with protruding rings 33 between adjacent extension pipes 31. The protruding rings 33 have an arc-shaped cross-section and a rotating structure. The protruding rings 33 connect to and seal the extension pipes 31. One end of the pipe 31 is provided with an air inlet funnel 32. The flared end of the air inlet funnel 32 is connected to an adjacent extension pipe 31. The constricted end of the air inlet funnel 32 is connected to the air supply pipe 21. Several extension pipes 31 are provided with a top cover cup 311 at the end away from the air inlet funnel 32. The mouth of the top cover cup 311 is connected to the extension pipe 31. The top cover cup 311 is provided with an exhaust pipe 312 for discharging excess waste gas. The end of the exhaust pipe 312 away from the top cover cup 311 is connected to the oil cyclone dust collector 4. The residual material collection area of ​​the cyclone dust collector 4 is provided with a residual material discharge pipe 41 for collecting excess waste material. Beneficially, the end of the vent pipe 312 away from the top cover bowl 311 is connected to a cyclone dust collector 4. The residual material collection area of ​​the cyclone dust collector 4 is provided with a residual material discharge pipe 41 to collect excess waste. The attached drawing adopts an exaggerated drawing style and is not the actual connection structure. It mainly shows the positional relationship. In reality, a side connection is used.

[0020] The vent hood contains several vertically arrayed boiling boxes for heating materials. Each boiling box has a material inlet / outlet device that passes through the vent hood. Specifically, the boiling box includes a rectangular tube 34 located in the middle of an extension tube 31. Connecting fins 341, which are vertical thin plates, are used to fix the rectangular tube 34 to the extension tube 31. A perforated plate 351 is located at the end of the rectangular tube 34 near the air inlet funnel 32. (The attached diagram uses a simplified drawing style; the actual number of holes is much greater than the number shown.) Two sets of flow equalization plates are located on the side of the perforated plate 351 away from the rectangular tube 34 to evenly blow in airflow. One of the two sets of flow equalization plates is vertically rotated and stacked.

[0021] Beneficially, the flow equalization plate includes a flow equalization frame 35, within which are arranged a plurality of planar arrays of vertical air guide plates 352. The vertical air guide plates 352 are vertically positioned on the equipment support plane. Rotating rods 3521 are provided at both ends of the vertical air guide plates 352, located in the area of ​​the vertical air guide plates 352 away from the support plane, near the edge of the long side. The rotating rods 3521 are connected to and rotatably attached to the inner frame of the flow equalization frame 35. Symmetrically arranged magnetic semi-guide strips 353 are provided on both sides of the plane of the vertical air guide plates 352. The cross-section of the semi-circular, semi-elliptical, or semi-teardrop-shaped sweeping structure of the semi-guide strip 353 is advantageous. The magnetic semi-guide strip 353 is slidably connected to the vertical guide plate 352. The closer the magnetic semi-guide strip 353 is to the air inlet funnel 32, the further away the relative position of the magnetic semi-guide strip 353 to the vertical guide plate 352 is from the rotating rod 3521 that is rotatably connected. The position can be changed by adjusting the anti-detachment protrusion 3531 on the magnetic semi-guide strip 353 to the anti-detachment groove 3522 on the vertical guide plate 352, so as to prevent the magnetic semi-guide strip 353 from falling off.

[0022] Beneficially, a bracelet-shaped ring 331 is provided on the inner side of the protruding ring 33. The bracelet-shaped ring 331 has a semi-circular rotating structure, and several fixed fins 3311 are provided between the bracelet-shaped ring 331 and the protruding ring 33.

[0023] In practice, the gas flows directly through the gap to the air outlet pipe 312 above the top cover bowl 311, causing the rectangular tubes 34, except for the bottom rectangular tubes 34, to be unable to be blown by the airflow. In order to adjust the gas flow direction, a bracelet-shaped ring 331 is provided between the protruding rings 33, so that there is an arc-shaped channel between them. When the gas flows in the gap, it first passes through one end of the arc-shaped groove, and then is blown into the lower part of the rectangular tubes 34 by the guiding effect of the arc-shaped groove, so that the hot air below can continue to enter the middle rectangular tubes 34.

[0024] Beneficially, the rectangular tube 34 is provided with a plurality of air guide baffles 343, which are evenly placed on both sides of the inner cavity of the rectangular tube 34 in an inclined array away from the perforated plate 351. The adjacent air guide baffles 343 overlap in the vertical projection of the plane of the perforated plate 351. The inner cavity of the rectangular tube 34 is also provided with a ventilation baffle 342, which is placed in the opposite direction to the air guide baffles 343 and abuts against the three sides of the inner cavity of the rectangular tube 34. The ventilation baffle 342 is located at the end of the plurality of air guide baffles 343 away from the perforated plate 351.

[0025] Beneficially, the rectangular tube 34 is provided with an inlet pipe 36 and an outlet pipe 37 on both sides of the contact surface of the air guide baffle 343. The inlet pipe 36 and the outlet pipe 37 pass through the rectangular tube 34. The connection ports of the inlet pipe 36 and the outlet pipe 37 are located on both sides of the cavity between the several air guide baffles 343 and the perforated plate 351. A rotating block 364 is provided at one end of the inlet pipe 36 and the outlet pipe 37 near the rectangular tube 34. The rotating block 364 is provided with a venting notch 3641. The feed pipe 36 has a wide inlet 361 in the middle, and the discharge pipe 37 has a long discharge pipe 371 at the end away from the rectangular tube 34. A rotating shaft 363 is provided on the central axis of the feed pipe 36 and the discharge pipe 37. The discharge pipe 37 and the discharge pipe 37 are also provided with a drive motor 362. The drive motor 362 drives the adjacent rotating shaft 363 to rotate. A rotating block 364 is provided at the end of the rotating shaft 363 near the rectangular tube 34. Two adjacent sets of rotating blocks 364 abut against each other.

[0026] Working principle of this utility model: The operator first feeds the calcining material through the inlet into the feed pipe 36. Then, the drive motor 362 is started to rotate the rotating shaft 363, which drives the ventilation gaps 3641 on the two sets of rotating blocks 364 to be opened. This allows the material in the feed pipe 36 to flow into the perforated plate 351 through the rectangular tube 34. The rotating block 364 is then rotated so that the two sets of ventilation gaps 3641 are staggered to form a sealing structure, and the calcination work can then begin. After hot air is delivered through the heating furnace 1, the blower 2 is started and input into the air inlet funnel 32 through the air supply pipe 21. A large amount of hot air first passes through the gap of the vertical air guide plate 352 on the nearest flow equalization frame 35, and then blows the material through the perforated plate 351 for baking. However, since the rectangular tube 34 is set in a three-dimensional multi-layer structure, the wind speed and intensity of the rectangular tube 34 near the air inlet funnel 32 will be greater than that of the rectangular tube 34 above. Therefore, it is necessary to reduce the wind speed at the bottom and increase the wind speed at the top: adjust the relative height of the magnetic semi-guide strip 353 and the vertical air guide plate 352. The closer the magnetic semi-guide strip 353 on the vertical air guide plate 352 near the lower air inlet funnel 32 is to the air inlet funnel 32, the more air flows through the magnetic semi-guide strip 353 between the two sets of vertical air guide plates 352. The air flow causes the two sets of vertical air guide plates 352 to move away from the rotation axis. When the ends of the 363 are close to each other, the area with a large air volume is affected by the gap, which reduces the inflow and thus reduces the air volume. The vertical air guide plate 352, which is further away from the air inlet funnel 32, is higher because the magnetic semi-guide strip 353 is higher. After the gas flows into the two sets of vertical air guide plates 352, it first passes through the straight area of ​​the vertical air guide plate 352, and then passes between the magnetic semi-guide strips 353. Since the magnetic semi-guide strip 353 is close to the rotating rod 3521, the rotational force is greater, which causes the vertical air guide plate 352 to not rotate. The smaller gap increases the permeability pressure and provides greater energy, which facilitates a stronger airflow to the upper rectangular tube 34. At the same time, the two vertically set vertical air guide plates 352 can evenly divide the air, ensuring that the airflow in each area is kept as uniform as possible. After passing through the perforated plate 351, it flows into the rectangular tube 34 to achieve roasting.

[0027] At the same time, even if the airflow below the perforated plate 351 is controlled, excessive airflow can still cause the roasting material to fly out of the rectangular tube 34. To solve this problem, the strong airflow is diagonally directed by the stepped air guide baffle 343. During the diagonal flow of the airflow below, it will also obstruct the airflow at the same position. Finally, the airflow is guided to the other side of the air guide baffle 343 away from the perforated plate 351 by the ventilation baffle 342. The airflow intensity is greatly reduced, and the roasting material is carried away from the other side of the air guide baffle 343 away from the perforated plate 351 and falls onto the perforated plate 351, preventing the material from flowing out. Meanwhile, due to the gap between the extension tube 31 and the rectangular tube 34, the gas will flow directly through the gap to the exhaust pipe 312 above the top cover bowl 311. This results in the rectangular tubes 34, except for the bottom rectangular tubes 34, not being blown by the airflow. In order to adjust the gas flow direction, a bracelet-shaped ring 331 is provided between the protruding rings 33, so that an arc-shaped channel is left between the two. When the gas flows in the gap, it first passes through one end of the arc-shaped groove and is then blown into the bottom of the rectangular tube 34 by the guiding effect of the arc-shaped groove. This allows the hot air below to continue to enter the middle rectangular tube 34, thereby achieving the roasting of the rectangular tube 34.

[0028] After roasting, the drive motor 362 on the discharge pipe 37 continues to rotate, so that the two sets of rotating blocks 364 on the discharge pipe 37 are connected. The hot air drives the roasted particles through the air guide baffle 343 and the space below the perforated plate 351 and then continues to flow out through the discharge long pipe 371 for further collection, thus realizing the collection of materials.
