The hot air is recovered after passing through the baking layer, resulting in a large waste of energy. When multiple layers are stacked, the air volume of the baking layer at the bottom is too large, causing the material to flow out directly through the air outlet, while the top baking layer cannot achieve the baking effect. The overall temperature is uneven and cannot be directly used, resulting in deviations in the quality of materials in the same furnace, seriously affecting the morphological structure of the same batch of porcelain products, making them unusable.

[0014] In one embodiment, a method for using the energy-saving boiling furnace is also included, and the specific method of use is as follows:

[0015] S1. Use the material through the required roasting material into the boiling box;

[0016] S2. Start the heating furnace to heat, and then use the blower to flow the heated gas through the gas pipeline into the vent hood;

[0017] S3. Pass a certain length of time for roasting, and after completion, use the material to flow out of the roasted material;

[0018] S4. Repeat steps S1 and S3 to complete the continuous roasting function.

[0019] The beneficial effects of the present invention are as follows: the present invention is an energy-saving boiling furnace system with good thermal energy utilization efficiency, which realizes multi-stage and multi-layer baking without the need to control the air volume, and its use method. The specific implementation method is as follows:

[0020] The operator first passes the roasting material through the feed port and flows into the feed pipe. Then, the drive motor is started to rotate the rotary shaft to drive the ventilation gaps on the two sets of rotating blocks to penetrate, so that the material in the feed pipe flows into the porous plate through the rectangular tube. The rotating block is rotated to make the two sets of ventilation gaps cross and stagger to form a blocking structure, and then the roasting work can begin.

[0021] After the hot air is sent out through the heating furnace, the blower is started and input into the air inlet funnel through the air supply pipeline. A large amount of hot air first passes through the gap of the vertical air guide plate on the nearest equalizing frame, and then blows the material through the porous plate for baking. However, since the rectangular tube is arranged in three-dimensional multi-layers, the wind speed and intensity of the rectangular tube close to the air inlet funnel will be greater than the rectangular tube above, so the wind speed below needs to be reduced and the wind speed above needs to be increased: adjust the relative height of the magnetic semi-air guide strip and the vertical air guide plate. The closer the magnetic semi-air guide strip on the vertical air guide plate close to the lower air inlet funnel is to the air inlet funnel, after a large air volume passes through the magnetic semi-air guide strip between the two sets of vertical air guide plates, the flow of gas causes the two sets of vertical air guide plates to meet at one end away from the rotation axis. The areas with large air volume are close to each other, and the areas with large air volume are affected by the gaps close to each other, thereby reducing the inflow and resulting in reduced air volume. The vertical air guide plates that are further away from the air inlet funnel have higher heights of magnetic semi-air 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 through the magnetic semi-air guide strips. Since the magnetic semi-air guide strips are close to the rotating rod, the rotation-induced capacity is relatively large, resulting in the vertical air guide plates not rotating. When the gap becomes smaller, it will increase the air permeability pressure and provide greater energy, which is convenient for stronger wind blowing on the high-rise rectangular tubes. At the same time, the two vertical layers of vertical air guide plates can divide the air evenly, ensuring that the airflow in each area is as uniform as possible and then flows into the rectangular tube after passing through the porous plate to achieve roasting.

[0022] At the same time, even if the air volume below the porous plate is controlled, excessive air volume will still cause the roasting materials to fly out of the rectangular tube. To solve this problem, a stepped air guide baffle is used to diagonally guide the strong airflow. During the diagonal outflow of the airflow below, it will also hinder the airflow at the same position. Finally, the airflow is guided into the other side of the air guide baffle away from the porous plate through the ventilation baffle, and the airflow intensity is greatly reduced. The entrained roasting materials fall onto the porous plate from the other side of the air guide baffle away from the porous plate, preventing the material from flowing out.

[0023] At the same time, due to the gap between the extension tube and the rectangular tube, the gas will directly pass through the gap and flow out to the exhaust pipe above the top cover bowl, resulting in that except for the rectangular tube at the bottom, the remaining rectangular tubes cannot be blown by the airflow. In order to adjust the gas flow direction, a bracelet ring is provided between the protruding rings, 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 groove, and is blown into the bottom of the rectangular tube by the guiding effect of the arc groove, so that the hot air below can continue to pass into the rectangular tube in the middle, thereby realizing the roasting inside the rectangular tube.

[0024] After roasting is completed, continue to rotate the drive motor on the discharge pipe so that the two sets of rotating blocks on the discharge pipe are connected. The hot air drives the roasted particles through the air guide baffle and the space under the porous plate and then continues to flow out through the long discharge pipe for further collection, thereby realizing the collection of materials.

[0025] The equipment has a simple structure and effectively utilizes a special air guide structure to effectively solve the problem of high-rise hot air transportation and the problem of material entrainment when large air volumes pass through, effectively realizing the efficient use of hot air and saving energy. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The ventilation hood houses several boiling boxes arranged in a vertical array for heating materials. These boxes are equipped with material passages that penetrate the ventilation hood for the entry and exit of materials. Specifically, the boiling boxes include a rectangular tube 34, located in the middle of the extension tube 31. Connecting fins 341 are provided between the rectangular tube 34 and the extension tube 31 for securing them. Connecting fins 341 are vertical thin plates.

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.

[0044] Beneficially, a plurality of air guide baffles 343 are provided in the rectangular tube 34, and the plurality of air guide baffles 343 are evenly placed in an array on both sides of the inner cavity of the rectangular tube 34 with a tendency to be inclined away from the porous plate 351, and adjacent air guide baffles 343 partially overlap with the vertical projection of the plane of the porous plate 351. A ventilation baffle 342 is also provided in the inner cavity of the rectangular tube 34, and the ventilation baffle 342 is placed in the opposite oblique direction of the air guide baffle 343 and abuts against three sides of the inner cavity of the rectangular tube 34.

A wide feed opening 361 is provided in the middle of the material tube 36, and a long discharge tube 371 is provided at the end of the discharge tube 37 away from the rectangular tube 34. A rotating shaft 363 is provided on the central axis of the feed tube 36 and the discharge tube 37. The discharge tube 37 and the discharge tube 37 are also provided with a driving motor 362. The driving motor 362 drives the adjacent rotating shaft 363 to rotate. A rotating block 364 is provided at the end of the rotating shaft 363 close to the rectangular tube 34, and two adjacent groups of rotating blocks 364 abut against each other.

[0046] The invention also includes a method for using the energy-saving boiling furnace, and the specific method of use is as follows:

[0047] S1. Use the material through the required roasting material into the boiling box;

[0048] S2 starts the heating furnace 1 for heating, and then uses the blower 2 to flow the heated gas through the gas pipeline 21 into the vent hood;

[0049] S3. Pass a certain length of time for roasting, and after completion, use the material to flow out of the roasted material;

[0050] S4. Repeat steps S1 and S3 to complete the continuous roasting function.

[0051] Working principle of the present invention:

[0052] The operator first passes the roasting material through the feed port and into the feed pipe 36. Then, the operator starts the drive motor 362 to rotate the rotary shaft 363, driving the ventilation gaps 3641 on the two sets of rotating blocks 364 to penetrate, so that the material in the feed pipe 36 flows through the rectangular tube 34 and into the porous plate 351. The operator then rotates the rotating blocks 364 so that the two sets of ventilation gaps 3641 are staggered and blocked to form a sealing structure, and then the roasting process can begin.

[0053] After the hot air is sent out through the heating furnace 1, the blower 2 is started and input into the air inlet funnel 32 through the air supply pipeline 21. A large amount of hot air first passes through the gap between the vertical air guide plate 352 on the nearest flow equalizing frame 35, and then blows the material through the porous plate 351 for baking. However, since the rectangular tube 34 is arranged in a three-dimensional multi-layer, the wind speed and intensity of the rectangular tube 34 close to the air inlet funnel 32 will be greater than the rectangular tube 34 above, so it is necessary to reduce the wind speed below and increase the wind speed above: adjust the relative height of the magnetic semi-air guide strip 353 and the vertical air guide plate 352. The closer the magnetic semi-air guide strip 353 on the vertical air guide plate 352 close to the lower air inlet funnel 32 is to the air inlet funnel 32, after a large amount of air passes through the magnetic semi-air guide strip 353 between the two sets of vertical air guide plates 352, the flow of gas causes the two sets of vertical air guide plates 352 to move away from the rotation axis. One end of 363 is close to each other, and the area with large air volume is affected by the gap close to reduce the inflow and thus reduce the air volume. The vertical air guide plate 352 that is further away from the air inlet funnel 32 has a higher height of the magnetic semi-air guide strip 353. After the gas flows into the two groups of vertical air guide plates 352, it first passes through the straight area of ​​the vertical air guide plate 352, and then passes through between the magnetic semi-air guide strips 353. Since the magnetic semi-air guide strip 353 is close to the rotating rod 3521, the rotation-induced capacity is large, resulting in the vertical air guide plate 352 not rotating. When the gap becomes smaller, it will increase the air permeability pressure and provide greater energy, which is convenient for the high-rise rectangular tube 34 to have a stronger wind blowing. At the same time, the two vertical layers of vertical air guide plates 352 can divide the air evenly to ensure that the airflow in each area is kept as uniform as possible and then flows into the rectangular tube 34 after passing through the porous plate 351 to achieve roasting.

[0054] At the same time, even if the air volume below the porous plate 351 is controlled, excessive air volume will still cause the roasting material to fly out of the rectangular tube 34. To solve this problem, a stepped air guide baffle 343 is used to diagonally guide the strong air flow. During the diagonal outflow of the air flow below, it will also hinder the air flow at the same position. Finally, the air flow is guided into the other side of the air guide baffle 343 away from the porous plate 351 through the ventilation baffle 342, and the air flow intensity is greatly reduced. The entrained roasting material falls onto the porous plate 351 from the other side of the air guide baffle 343 away from the porous plate 351, thus preventing the material from flowing out.

[0055] At the same time, since there is a gap between the extension tube 31 and the rectangular tube 34, the gas will directly pass through the gap and flow out to the air outlet pipe 312 above the top cover bowl 311, resulting in that except for the rectangular tube 34 at the bottom, the remaining rectangular tubes 34 cannot be blown by the airflow. In order to adjust the gas flow direction, a bracelet 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 groove, and is blown into the bottom of the rectangular tube 34 by the guiding effect of the arc groove, so that the hot air below can continue to pass into the middle rectangular tube 34, thereby realizing roasting inside the rectangular tube 34.

[0056] After the roasting is completed, the driving 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 under the porous plate 351 and then continues to flow out through the long discharge pipe 371 for further collection, thereby realizing the collection of materials.
