Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a high-efficiency hot air furnace with three-dimensional space. Background Technology

[0002] A hot air furnace is a drying device that primarily uses hot air circulation to evaporate moisture from products, thus achieving the drying purpose. Existing hot air furnaces typically consist of a long, straight conveyor track inside the equipment, with heating mechanisms installed above or below the track. These heating mechanisms radiate heat onto the products on the track, and fans are installed in each temperature zone to bake and solidify the products. However, this results in a large equipment size, requiring significant production space, and inefficient maintenance. Furthermore, because all products are placed individually on the track, they tend to stick together, making it difficult to separate larger or heavier products and hindering connections to subsequent equipment.

[0003] Therefore, it is necessary to provide a high-efficiency hot blast stove with a three-dimensional space to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a high-efficiency hot air furnace with three-dimensional space to solve the problems of existing hot air furnaces, such as large size, large production space occupation, low maintenance efficiency, easy connection of products, difficulty in separation, and inconvenience for connecting to downstream equipment.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-dimensional high-efficiency hot air furnace, which includes: a heating box, a lifting bar input mechanism, a lifting bar output mechanism, a hot air heating mechanism, an input transmission mechanism, an output transmission mechanism, and a push plate mechanism;

[0006] The heating chamber has a heating cavity inside. The heating chamber has an input opening and an output opening on both sides that communicate with the heating cavity. The input transmission mechanism is raised and lowered at the input opening, and the output transmission mechanism is raised and lowered at the output opening. Multiple hot air heating mechanisms are arranged on the inner walls of both sides of the heating cavity.

[0007] Both the lifting bar input mechanism and the lifting bar output mechanism are located inside the heating chamber. Both the lifting bar input mechanism and the lifting bar output mechanism are located between the input transmission mechanism and the output transmission mechanism. The lifting bar input mechanism is located close to the input transmission mechanism, and the lifting bar output mechanism is located close to the output transmission mechanism.

[0008] Both the lifting support bar input mechanism and the lifting support bar output mechanism include sprockets, two sets of chains, and support plates. The rotation axes of the two sets of chains are parallel. Multiple sprockets are connected to the inner side of the chain in a ring structure. Multiple support plates are fixedly arranged on the outer side of the chain. The support plates between the two sets of chains lift the product and perform lifting and lowering. The rotation axes of the chains of the lifting support bar input mechanism and the lifting support bar output mechanism are coaxial, and the running directions of the chains of the lifting support bar input mechanism and the lifting support bar output mechanism are opposite.

[0009] The pusher mechanism is located at the end of the conveying direction of the lifting bar input mechanism and is used to push the product on the lifting bar input mechanism to the lifting bar output mechanism.

[0010] In this utility model, both the lifting bar input mechanism and the lifting bar output mechanism include three sprockets. The three sprockets make the chain triangular, with the two sprockets at both ends located on the same vertical line, and the two sets of chains are close to each other and the chain segments between the two sprockets at both ends are parallel. The middle sprocket is connected to the motor drive.

[0011] The two sets of chains are arranged one-to-one on two movable frames, which are slidably connected to the inner wall of the heating chamber, and the sliding trajectory of the movable frames is perpendicular to the transmission trajectory of the input transmission mechanism.

[0012] The heating box is rotatably equipped with a width-adjusting screw. The two ends of the width-adjusting screw have threaded sections with opposite directions of rotation. The threaded sections at both ends are connected to the two movable frames in a corresponding manner to drive the two movable frames to move closer to or further away from each other.

[0013] In this invention, two adjustable lead screws are connected at different heights of the movable frame. A drive rod is rotatably mounted on the heating box. One end of the drive rod extends outside the heating box and is connected to an operating handle. The other end of the drive rod is connected to the two adjustable lead screws via a transmission rod.

[0014] In this utility model, both the input transmission mechanism and the output transmission mechanism include a lifting cylinder, a transmission platform, and a transmission belt. The transmission platform is connected to the output end at the top of the lifting cylinder. A U-shaped groove is provided on the top of the transmission platform. The transmission belts are provided on two opposite side walls inside the transmission platform. The two sets of transmission belts support and transport the product.

[0015] In this utility model, the three-dimensional high-efficiency hot air furnace includes two sets of pusher mechanisms. The positions of the two sets of pusher mechanisms correspond one-to-one with the positions of the lifting support bar input mechanism and the lifting support bar output mechanism, and the pusher trajectories of the two sets of pusher mechanisms simultaneously cover the area between the lifting support bar input mechanism and the lifting support bar output mechanism.

[0016] In this utility model, the push plate mechanism includes a push plate linear drive, a fixed block, a push plate cylinder, and a push plate body. The push plate linear drive is disposed on the inner wall of the heating box. The output end of the push plate linear drive is connected to the fixed block to drive the fixed block to slide. The sliding trajectory of the fixed block covers the lifting support bar input mechanism and the lifting support bar output mechanism. The push plate cylinder is fixedly connected to the fixed block. The push plate body is connected to the output end of the push plate cylinder. The push plate cylinder drives the push plate body to move closer to or away from the lifting support bar input mechanism and the lifting support bar output mechanism.

[0017] In this utility model, the hot air heating mechanism includes a fan, an air guide box, and a heating element. The air guide box is connected to the inner wall of the heating box. The heating element is disposed inside the air guide box. The output port of the fan is connected to the inner cavity of the air guide box. An air outlet is provided on the side of the air guide box near the lifting bar input mechanism and the lifting bar output mechanism.

[0018] In this embodiment, heat insulation cotton is provided between the air guide box and the inner wall of the heating box.

[0019] In this invention, the top of the heating chamber is provided with an exhaust vent that connects the heating cavity to the external space.

[0020] Compared with the prior art, the advantages of this utility model are as follows: The high-efficiency hot air furnace of this utility model with three-dimensional space, by setting up lifting bar input mechanism and lifting bar output mechanism, allows products to be stacked at a certain interval and transported back and forth along the vertical space of the heating chamber. The products are not easy to stick together, which improves the drying time and efficiency of the products, while the size of the equipment is smaller. Attached Figure Description

For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Existing hot blast stoves typically use long, straight conveyor tracks to transport products, resulting in large equipment size, requiring significant production space, and inefficient and time-consuming maintenance. Furthermore, because products are all individually positioned on the track, they tend to stick together, making it difficult to separate larger and heavier products and hindering the connection to subsequent equipment.

[0030] The following is a preferred embodiment of a three-dimensional high-efficiency hot blast stove provided by this utility model, which can solve the above-mentioned technical problems.

[0031] Please refer to Figures 1-4 In the diagram, units with similar structures are represented by the same labels.

[0032] This embodiment provides a high-efficiency hot air furnace in a three-dimensional space, which includes: a heating box 11, a lifting support bar input mechanism 12, a lifting support bar output mechanism 13, a hot air heating mechanism 17, an input transmission mechanism 16, an output transmission mechanism 15, and a push plate mechanism 14.

[0033] The heating chamber 11 has a heating cavity 111 inside. The heating chamber 11 has an input opening and an output opening on both sides that connect to the heating cavity 111. The input transmission mechanism 16 is raised and lowered at the input opening, and the output transmission mechanism 15 is raised and lowered at the output opening. Multiple hot air heating mechanisms 17 are arranged on the inner walls of both sides of the heating cavity 111.

[0034] The lifting bar input mechanism 12 and the lifting bar output mechanism 13 are both located inside the heating chamber 111. The lifting bar input mechanism 12 and the lifting bar output mechanism 13 are both located between the input transmission mechanism 16 and the output transmission mechanism 15. The lifting bar input mechanism 12 is located close to the input transmission mechanism 16 to receive the product on the input transmission mechanism 16, and the lifting bar output mechanism 13 is located close to the output transmission mechanism 15 to transport the product to the output transmission mechanism 15.

[0035] Please refer to Figures 2-4 Specifically, in this embodiment, the lifting bar input mechanism 12 and the lifting bar output mechanism 13 have the same structure. Both the lifting bar input mechanism 12 and the lifting bar output mechanism 13 include a sprocket 21, two sets of chains 22, and a bar plate 23.

[0036] The two sets of chains 22 have parallel rotation axes so that they can drive the product to rise and fall together. Multiple sprockets 21 are connected to the inner side of the ring-shaped chain 22, allowing the chain 22 to rotate cyclically. Multiple support plates 23 are fixedly installed on the outer side of the chain 22, and the support plates 23 between the two sets of chains 22 support the product and move it up and down.

[0037] The rotation axes of the chains 22 of the lifting bar input mechanism 12 and the lifting bar output mechanism 13 are coaxially arranged, that is, the distance between the two sets of chains of the lifting bar input mechanism 12 is equal to the distance between the two sets of chains of the lifting bar output mechanism 13, and products of the same batch can be transferred between the lifting bar input mechanism 12 and the lifting bar output mechanism 13.

[0038] The chains 22 of the lifting bar input mechanism 12 and the lifting bar output mechanism 13 run in opposite directions. That is, the product can first rise through the lifting bar input mechanism 12 and then fall through the lifting bar output mechanism 13, or the product can first fall through the lifting bar input mechanism 12 and then rise through the lifting bar output mechanism 13. This can make full use of the vertical space in the heating chamber 111, improve the drying time and efficiency of the product, and at the same time, the size of the equipment is smaller.

[0039] The push plate mechanism 14 is located at the end of the conveying direction of the lifting bar input mechanism 12 and is used to push the product on the lifting bar input mechanism 12 to the lifting bar output mechanism 13.

[0040] Please refer to Figure 3 and Figure 4 In this embodiment, both the lifting bar input mechanism 12 and the lifting bar output mechanism 13 include three sprockets 21. The three sprockets 21 make the chain 22 triangular, which makes the chain relatively taut and the conveying stable. The two sprockets 21 at both ends are located on the same vertical line, and the two sets of chains 22 are close to each other. The chain segments between the two sprockets 21 at both ends are parallel, so the product can be stably positioned between the two parallel chain segments. The middle sprocket 21 is connected to the motor drive to drive the chain 22 to rotate.

[0041] Two sets of chains 22 are arranged one-to-one on two movable frames 24. The movable frames 24 are slidably connected to the inner wall of the heating chamber 111. The sliding trajectory of the movable frames 24 is perpendicular to the transmission trajectory of the input transmission mechanism 16.

[0042] Specifically, a width-adjusting screw 183 is rotatably mounted on the heating box 11. The two ends of the width-adjusting screw 183 have threaded sections with opposite directions of rotation. The threaded sections at both ends are connected to the two movable frames 24 in a corresponding manner to drive the two movable frames 24 to move closer or further apart from each other, thereby adjusting the distance between the two sets of chains 22 for conveying products of different sizes and specifications.

[0043] In this embodiment, two width-adjusting lead screws 183 are connected at different height positions of the movable frame 24. A drive rod 181 is rotatably mounted on the heating box 11. One end of the drive rod 181 extends outside the heating box 11 and is connected to the operating handle 185. The other end of the drive rod 181 is connected to the two width-adjusting lead screws 183 through a transmission rod 182. One drive rod 181 drives the two width-adjusting lead screws 183 to rotate, thereby stably driving the two movable frames 24 to move.

[0044] Specifically, the drive rod 181 and the transmission rod 182, and the transmission rod 182 and the width-adjusting lead screw 183, can be connected by a linkage reversing assembly 184. The linkage reversing assembly can be, for example, but not limited to, a meshing transmission structure of two bevel gears, to achieve a change in transmission direction.

[0045] In this embodiment, both the input transmission mechanism 16 and the output transmission mechanism 15 include a lifting cylinder 31, a transmission platform 32, and a transmission belt 33. The transmission platform 32 is connected to the output end at the top of the lifting cylinder 31. A U-shaped groove is provided at the top of the transmission platform 32. Transmission belts 33 are provided on two opposite side walls inside the transmission platform 32. The two sets of transmission belts 33 support and transport the product.

[0046] The input transmission mechanism 16's transmission platform 32 lowers to place the product onto the support plate 23, allowing the product to be conveyed upwards with the chain 22. The output transmission mechanism 15's transmission platform 32 rises to lift the product on the support plate 23, enabling the conveyor belt 33 to output the product.

[0047] In this embodiment, the high-efficiency hot air furnace in three-dimensional space includes two sets of push plate mechanisms 14. The positions of the two sets of push plate mechanisms 14 correspond one-to-one with the positions of the lifting support bar input mechanism 12 and the lifting support bar output mechanism 13, and the push plate trajectories of the two sets of push plate mechanisms 14 simultaneously cover the area between the lifting support bar input mechanism 12 and the lifting support bar output mechanism 13.

[0048] After the push plate mechanism 14 pushes the product out of the lifting support bar input mechanism 12, the lifting support bar input mechanism 12 and the input transmission mechanism 16 can start working. Meanwhile, another push plate mechanism 14 pushes the product to the set position on the lifting support bar output mechanism 13, which can improve the overall work efficiency.

[0049] Specifically, the pusher mechanism 14 includes a pusher linear drive 141, a fixed block 142, a pusher cylinder 143, and a pusher body 144. The pusher linear drive 141 can be, but is not limited to, a motor screw mechanism, a linear motor, or an electric push rod. The pusher linear drive 141 is disposed on the inner wall of the heating chamber 11, and its output end is connected to the fixed block 142 to drive the fixed block 142 to slide. The sliding trajectory of the fixed block 142 covers the lifting bar input mechanism 12 and the lifting bar output mechanism 13. The pusher cylinder 143 is fixedly connected to the fixed block 142, and the pusher body 144 is connected to the output end of the pusher cylinder 143. The pusher cylinder 143 drives the pusher body 144 to move closer to or further away from the lifting bar input mechanism 12 and the lifting bar output mechanism 13.

[0050] Please refer to Figure 3 and Figure 4 In this embodiment, the hot air heating mechanism 17 includes a fan 171, an air guide box 172, and a heating element 173. The air guide box 172 is connected to the inner wall of the heating chamber 11, the heating element 173 is disposed inside the air guide box 172, the output port of the fan 171 is connected to the inner cavity of the air guide box 172, and an air outlet 174 is provided on the side of the air guide box 172 near the lifting support bar input mechanism 12 and the lifting support bar output mechanism 13. Hot air can pass through the gap between the support bar plates 23 to dry the product effectively, and the heat can quickly and evenly fill the entire heating chamber 111.

[0051] Preferably, heat insulation cotton is provided between the air guide box 172 and the inner wall of the heating box 11 to reduce heat loss.

[0052] In this embodiment, the top of the heating chamber 11 is provided with an exhaust vent 112 that connects the heating chamber 111 and the external space, which can be used to discharge exhaust gas.

[0053] It should be noted that in this embodiment, the product position is sensed by corresponding sensors during the process of being transported on the lifting support input mechanism 12, the lifting support output mechanism 13, the input transmission mechanism 16, and the output transmission mechanism 15.

[0054] The working principle of this utility model is as follows: First, the product is transported to the inner side of the lifting support bar input mechanism 12 through the input transmission mechanism 16. When the product is transported on the input transmission mechanism 16, the product and the upper and lower support bars 23 of the lifting support bar input mechanism 12 are both at a set distance. When the product is transported to the position, the transmission platform 32 of the input transmission mechanism 16 lowers to place the product on the support bar 23, so that the product can be transported upward with the chain 22.

[0055] When the product is conveyed to the top of the lifting support bar input mechanism 12 by the rising chain 22, the push plate mechanism 14 pushes the product on the lifting support bar input mechanism 12 onto the support bar plate 23 of the lifting support bar output mechanism 13. Then the product is conveyed to the bottom by the rising chain 22. When the product is conveyed to the set position by the rising chain 22, the transmission platform 32 of the output transmission mechanism 15 lifts the product on the support bar plate 23, so that the transmission belt 33 can output the product.

[0056] During the process of the product moving up and down on the lifting support bar input mechanism 12 and the lifting support bar output mechanism 13, the product is dried by hot air blowing through the hot air heating mechanism 17.

[0057] This completes the process of product conveying and drying using a three-dimensional high-efficiency hot air furnace according to this preferred embodiment.

[0058] This preferred embodiment of the high-efficiency hot air furnace in three-dimensional space, by setting up lifting bar input mechanism and lifting bar output mechanism, allows products to be stacked at certain intervals and transported back and forth along the vertical space of the heating chamber. The products are less likely to stick together, which improves the drying time and efficiency of the products, while the size of the equipment is smaller.

[0059] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
