Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a hot air drying device. Background Technology

[0002] Hot air drying equipment is a device that uses hot air to dry materials. It is widely used in the food, pharmaceutical, and chemical industries. Its working principle involves generating hot air through a heater and evenly distributing it into the drying chamber to promote the evaporation of moisture from the material surface. The equipment typically consists of a hot air generation system, a drying chamber, a conveyor belt, and a control system. The temperature and flow rate of the hot air can be adjusted to meet the drying requirements of different materials. The material is continuously dried within the drying chamber via the conveyor belt, resulting in high drying efficiency and convenient operation.

[0003] Because existing hot air drying equipment tends to cause materials to clump together or stick to the surface of the conveying components during the drying process, resulting in excessively thick material in some areas, the contact area between hot air and material is reduced, which is not conducive to rapid evaporation of moisture and reduces the drying efficiency of the hot air drying equipment. Therefore, it is necessary to improve the current hot air drying equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a hot air drying device to solve the problem mentioned in the background art that in the current hot air drying devices on the market, materials tend to clump together or stick to the surface of the conveying components, resulting in excessively thick local materials, which reduces the contact area between hot air and materials and is not conducive to rapid evaporation of moisture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot air drying device, comprising a body and a drive assembly, wherein a hot air drying assembly is installed on the top of the body, and uprights are fixedly connected to both ends of the body, the drive assembly is installed on the inner side of the uprights, and a conveyor belt is installed on the outer side of the drive assembly, and a shaking mechanism is installed on the inner side of the body near the conveyor belt, the shaking mechanism including a connecting frame fixedly connected to the inner wall of the body, a sliding rod slidably sleeved on the inner side of the connecting frame, a support spring sleeved on the outer side of the sliding rod, a lifting plate fixed to the top of the sliding rod, and a drive shaft mounted on the inner wall of the body near the bottom of the lifting plate via a bearing, and a lifting block fixedly connected to one end of the drive shaft near the outside of the body.

[0006] Preferably, a drive sprocket is fixedly sleeved at one end of the drive shaft near the outside of the machine body, and a chain is meshed with the outer side of the drive sprocket. A motor connected to the drive shaft via a coupling is installed on the outer wall of the machine body.

[0007] Preferably, the conveyor belt has fixed blocks that are evenly distributed on both sides, and the upper surface of the conveyor belt near the fixed blocks is provided with a plurality of bearing mesh plates, and the two ends of the bearing mesh plates are fixed with connecting shafts.

[0008] Preferably, the fixing block has a mating groove on its inner side near the connecting shaft, and a limit mechanism is installed at one end of the connecting shaft.

[0009] Preferably, the limiting mechanism includes a limiting hole, a return spring, a pull rod, a telescopic groove, and a limiting rod, and the connecting shaft has a telescopic groove at one end near the fixed block.

[0010] Preferably, a pull rod is slidably sleeved on the inner side of the telescopic groove, and limit rods are fixed on both sides of the pull rod.

[0011] Preferably, a limiting hole is provided on the outer wall of the fixing block near the limiting rod, and a return spring is sleeved on one end of the pull rod near the telescopic groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Equipped with a shaking mechanism and a motor, the motor drives the drive shaft to rotate when the conveyor belt is conveying materials. The drive shaft then drives the drive sprocket to rotate, which in turn drives the chain to rotate. This can drive three sets of drive shafts simultaneously. The drive shaft also drives the lifting plate to rotate. When the protruding end of the lifting plate contacts the bottom surface of the lifting plate, the lifting plate is squeezed and moves upward. At the same time, the lifting plate drives the slide rod to slide inside the connecting frame and squeeze the support spring. Subsequently, the lifting plate collides with the inside of the conveyor belt, causing the conveyor belt to shake. The support spring provides elastic support for the lifting plate's rise and fall. The shaking of the conveyor belt can prevent material accumulation or excessive thickness in some areas, help accelerate moisture evaporation, and improve the working efficiency of the hot air drying equipment.

[0013] 2. Equipped with a support mesh plate and a limiting mechanism, the material is placed in the support mesh plate, with a certain distance between the bottom surface of the support mesh plate and the surface of the conveyor belt. The support mesh plate allows hot air to contact the bottom surface of the material, improving the drying effect. When unloading is required, the pull rods can be pulled to both sides, causing the pull rods to slide in the telescopic groove and squeeze the return spring. At the same time, the pull rods drive the limiting rods to disengage from the limiting holes. Then, the pull rods are lifted upwards, causing the pull rods to drive the connecting shaft to disengage from the docking groove, facilitating the disassembly of the support mesh plate and promoting rapid unloading, thus improving the convenience of the hot air drying equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 The present invention provides a technical solution: a hot air drying device, comprising a body 1 and a drive assembly 4, wherein a hot air drying assembly 2 is installed on the top of the body 1, and a frame 5 is fixedly connected to both ends of the body 1, the drive assembly 4 is installed on the inner side of the frame 5, and a conveyor belt 3 is installed on the outer side of the drive assembly 4.

[0018] Please see Figures 1-5A shaking mechanism 9 is installed on the inner side of the machine body 1 near the conveyor belt 3. The shaking mechanism 9 includes a connecting frame 903 fixedly connected to the inner wall of the machine body 1. A slide rod 902 is slidably sleeved on the inner side of the connecting frame 903. A support spring 901 is sleeved on the outer side of the slide rod 902. A lifting plate 904 is fixedly fixed on the top of the slide rod 902. A drive shaft 14 is installed on the inner wall of the machine body 1 near the bottom of the lifting plate 904 via a bearing. A lifting block 15 is fixedly connected to one end of the drive shaft 14 near the outside of the machine body 1. A drive sprocket 11 is fixedly sleeved on one end of the drive shaft 14 near the outside of the machine body 1. A chain 12 is meshed on the outer side of the drive sprocket 11. A motor 13 connected to the drive shaft 14 via a coupling is installed on the outer wall of the machine body 1. The lifting block 15 is designed as a hoist structure.

[0019] In practice, when hot air drying equipment conveys and dries materials, the materials tend to clump together or adhere to the surface of the conveying components, resulting in excessively thick localized areas of material. This reduces the contact area between the hot air and the material, hindering rapid moisture evaporation and lowering the drying efficiency of the hot air drying equipment. To address this, while the conveyor belt 3 is conveying the material, the motor 13 drives the drive shaft 14 to rotate. The drive shaft 14 then drives the drive sprocket 11 to rotate, which in turn drives the chain 12. This allows for the simultaneous driving of three sets of drive shafts 14, which in turn drive the lifting block. When the lifting block 15 rotates, and the protruding end of the lifting block 15 contacts the bottom surface of the lifting plate 904, the lifting plate 904 is squeezed by the lifting block 15 and moves upward. At the same time, the lifting plate 904 drives the sliding rod 902 to slide inside the connecting frame 903 and squeeze the support spring 901. Then the lifting plate 904 collides with the inner side of the conveyor belt 3, causing the conveyor belt 3 to vibrate. The support spring 901 can provide elastic support for the lifting of the lifting plate 904. The vibration of the conveyor belt 3 can prevent material accumulation or excessive thickness in some areas, help accelerate the evaporation of moisture, and improve the working efficiency of the hot air drying equipment.

[0020] Please see Figures 1-3 and Figures 6-8The conveyor belt 3 has fixed blocks 8 evenly spaced on both sides. Several carrying mesh plates 6 are provided on the upper surface of the conveyor belt 3 near the fixed blocks 8. Connecting shafts 16 are fixed at both ends of the carrying mesh plates 6. A docking groove 10 is provided on the inner side of the fixed blocks 8 near the connecting shafts 16. A limiting mechanism 7 is installed at one end of the connecting shafts 16. The limiting mechanism 7 includes a limiting hole 701, a return spring 702, a pull rod 703, a telescopic groove 704, and a limiting rod 705. A telescopic groove 704 is provided at one end of the connecting shaft 16 near the fixed blocks 8. A pull rod 703 is slidably sleeved on the inner side of the telescopic groove 704. Limiting rods 705 are fixed on both sides of the pull rod 703. A limiting hole 701 is provided on the outer wall of the fixed blocks 8 near the limiting rods 705. A return spring 702 is sleeved on one end of the pull rod 703 near the telescopic groove 704.

[0021] In practice, since the side of the material that contacts the conveyor belt 3 is not easy to come into contact with hot air, affecting the drying effect, the material can be placed in the support mesh plate 6. The bottom surface of the support mesh plate 6 is a certain distance from the surface of the conveyor belt 3. The support mesh plate 6 allows the hot air to come into contact with the bottom surface of the material, improving the drying effect. When unloading is required, the pull rod 703 can be pulled directly to both sides, causing the pull rod 703 to slide in the telescopic groove 704 and squeeze the return spring 702. At the same time, the pull rod 703 drives the limit rod 705 to disengage from the limit hole 701. Then, the pull rod 703 is lifted upwards, causing the pull rod 703 to drive the connecting shaft 16 to disengage from the docking groove 10, which facilitates the disassembly of the support mesh plate 6, promotes rapid unloading, and improves the convenience of the hot air drying equipment.

[0022] Working principle: When using this hot air drying equipment, the material is first placed in the carrying mesh plate 6. The drive component 4 drives the conveyor belt 3 to rotate and move, conveying the material. Then the hot air drying component 2 dries the material. At the same time, the shaking mechanism 9 makes the conveyor belt 3 shake to avoid material accumulation and improve drying efficiency. After drying, the carrying mesh plate 6 is disassembled by the limiting mechanism 7 for convenient and quick unloading, which improves the working efficiency and convenience of the hot air drying equipment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
