Description

Technical Field

[0001] This utility model relates to the field of polyurethane particle processing technology, and more specifically, to a drying device for polyurethane particles. Background Technology

[0002] Polyurethane is a polymer material with high strength, tear resistance, and abrasion resistance. Due to its excellent properties, it is widely used in light industry, chemical industry, electronics, textiles, medical, construction, building materials, automotive, aerospace, and aviation fields. With the increasing demand for polyurethane products, its production scale is gradually expanding, and the requirements for the post-processing of polyurethane particles, including the drying process, are also increasing. Polyurethane particles can be dried using a rotary drum dryer.

[0003] However, existing rotary drum dryers often rely on fans to blow particles, transporting them while drying. The particle speed depends on the fan's power. When a large number of particles need to move slowly for thorough drying, the fan speed must be reduced, decreasing the efficiency of the drying air input and consequently affecting the drying effect. Therefore, we propose a drying device for polyurethane particles. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a drying device for polyurethane particles to solve the technical problem that the drying efficiency will decrease when the particle moving speed is slowed down in the current drying device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drying device for polyurethane particles, comprising a drying structure, a push-pull rod disposed within the drying structure, and a reciprocating drive structure installed at one end of the push-pull rod. The reciprocating drive structure includes a drive motor B, a turntable, a connecting rod, a push-pull block, and a limiting guide rod. The output end of the drive motor B is fixedly connected to the turntable. The outer front end of the turntable is rotatably connected to the connecting rod. The other end of the connecting rod is rotatably connected to the push-pull block. The push-pull block is slidably connected to the limiting guide rod through an opening slot. The push-pull block is fixedly connected to the push-pull rod. A plurality of diffusion structures are fixedly connected to the push-pull rod. The diffusion structure includes a collecting hopper and a dispersing plate. Both the collecting hopper and the dispersing plate are rotatably connected to the push-pull rod. The collecting hopper and the dispersing plate are arranged in opposite directions. The collecting hopper is provided with a through collecting groove.

[0006] Preferably, the drying structure includes a drying barrel, a connecting barrel, a drive motor A, a drive gear, and a drive gear ring. Both ends of the drying barrel are rotatably connected to the connecting barrel. The output end of the drive motor A is fixedly connected to the drive gear. The drive gear meshes with the drive gear ring, and the drive gear ring is installed on the outside of the drying barrel.

[0007] Preferably, one of the connecting barrels is connected to a feed pipe and a drying fan, and the other connecting barrel is connected to a storage silo.

[0008] Preferably, the inner wall of the drying barrel is provided with actuating plates installed in an equidistant ring, and the spacing between two adjacent actuating plates is adapted to a collecting plate.

[0009] Preferably, the collecting trough includes a large end and a small end. The small end of the collecting trough is close to the dispersing plate. The surface of the dispersing plate is provided with an inclined surface, and the small end of the inclined surface is close to the collecting hopper. The collecting hopper is fixedly connected to the collecting plate in an equidistant ring at its edge.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This invention uses a reciprocating drive structure and push-pull rod to drive the collecting hopper and dispersing plate to move back and forth, thereby repeatedly pushing polyurethane particles away from the end of the drying structure near the discharge port and allowing the polyurethane particles to remain on the collecting hopper for a certain period of time. This invention can actively extend the drying time of polyurethane particles in the equipment when needed, enhancing the drying effect of the equipment.

[0012] 2. This invention uses collection grooves of varying sizes to collect polyurethane particles, and then the inclined surface of the collection hopper allows the polyurethane particles to diffuse again. This process of aggregation and dispersion ensures that the polyurethane particles have sufficient contact with the dry air. By breaking up the polyurethane particles, this invention actively disperses the internal structure of the polyurethane particles, thereby ensuring uniform contact between the polyurethane particles and the dry air and optimizing the drying effect.

Detailed Implementation

[0018] like Figures 1 to 4 As shown, this utility model relates to a drying device for polyurethane particles, including a drying structure 1, a push-pull rod 2 disposed within the drying structure 1, and a reciprocating drive structure 3 installed at one end of the push-pull rod 2. The reciprocating drive structure 3 includes a drive motor B301, a turntable 302, a connecting rod 303, a push-pull block 304, and a limiting guide rod 305. The output end of the drive motor B301 is fixedly connected to the turntable 302, and the outer front end of the turntable 302 is rotatably connected to the connecting rod 303. The other end of the connecting rod 303... One end is rotatably connected to a push-pull block 304, which is slidably connected to a limiting guide rod 305 through a through groove. The push-pull block 304 is fixedly connected to a push-pull rod 2, and several diffusion structures 4 are fixedly connected to the push-pull rod 2. Each diffusion structure 4 includes a collecting hopper 401 and a dispersing plate 402, both of which are rotatably connected to the push-pull rod 2. The collecting hopper 401 and the dispersing plate 402 are arranged in opposite directions, and the collecting hopper 401 has a through collecting groove 403. This invention drives the collecting hopper 401 and the dispersing plate 402 to move back and forth through the reciprocating drive structure 3 and the push-pull rod 2, thereby repeatedly pushing polyurethane particles away from the end of the drying structure 1 near the discharge port and allowing the polyurethane particles to remain on the collecting hopper 401 for a certain period of time. This invention can actively extend the drying time of polyurethane particles in the equipment when needed, enhancing the drying effect of the equipment.

[0019] Furthermore, the drying structure 1 includes a drying barrel 101, a connecting barrel 102, a drive motor A103, a drive gear 104, and a drive gear ring 105. Both ends of the drying barrel 101 are rotatably connected to the connecting barrel 102. The output end of the drive motor A103 is bolted to the drive gear 104. The drive gear 104 meshes with the drive gear ring 105, and the drive gear ring 105 is snap-fitted to the outside of the drying barrel 101. This invention, by setting up the drive motor A103, drive gear 104, and drive gear ring 105, causes the drying barrel 101 to rotate, continuously tumbling the internal polyurethane particles and optimizing the drying performance.

[0020] Furthermore, one of the connecting barrels 102 is connected to a feed pipe 107 and a drying fan 108, and the other connecting barrel 102 is connected to a storage silo 109. This invention uses the feed pipe 107 and the drying fan 108 to transport raw materials and blow dry air, and the storage silo 109 to store the dried polyurethane particles.

[0021] Furthermore, the inner wall of the drying barrel 101 is provided with equidistant annular actuating plates 106 connected by bolts, and the spacing between two adjacent actuating plates 106 is adapted to accommodate a collecting plate 405. By providing the actuating plates 106, this invention optimizes drying performance by assisting in pushing the polyurethane particles to rotate within the drying barrel 101 during rotation.

[0022] In embodiments of this invention, in order for the collecting tank 403 to repeatedly collect and diffuse the polyurethane particles, allowing the polyurethane particles to disperse and contact with dry air, such as... Figure 3 This utility model discloses the specific structure of the collecting hopper 401 and the dispersing plate 402. The collecting trough 403 includes a large end and a small end, with the small end of the collecting trough 403 close to the dispersing plate 402. The surface of the dispersing plate 402 is provided with an inclined surface 404, and the small end of the inclined surface 404 is close to the collecting hopper 401. The collecting plate 405 is fixedly connected in an equidistant ring shape to the edge of the collecting hopper 401. This utility model collects polyurethane particles by setting up collecting troughs 403 of different sizes, and then the polyurethane particles are further dispersed by the inclined surface 404 of the collecting hopper 401. This aggregation and dispersion allows the polyurethane particles to fully contact the dry air. This utility model disperses the polyurethane particles by breaking them up, thereby making the polyurethane particles contact the dry air evenly and optimizing the drying effect.

[0023] Working principle: This embodiment provides a drying device for polyurethane particles. In use, polyurethane particles are fed into the feed hopper 102 through the feed pipe 107. The drying fan 108 blows the polyurethane particles into the drying hopper 101. The drive motor A drives the drive gear 104 to rotate, which in turn drives the drive gear ring 105 to rotate. The drive gear ring 105 then rotates the drying hopper 101. The drying hopper 101, via the agitator plate 106, causes the polyurethane particles to tumble, thus achieving drying. When it is necessary to increase the drying time... At that time, the drive motor B301 drives the turntable 302 to rotate, the turntable 302 drives the connecting rod 303 to move, the connecting rod 303 drives the push-pull block 304 to slide on the limit guide rod 305, the push-pull block 304 drives the push-pull rod 2 to move, the push-pull rod 2 pushes the collecting hopper 401 and the dispersing plate 402 to move repeatedly, the collecting hopper 401 and the dispersing plate 402 push the polyurethane particles forward, and the polyurethane particles are gathered and dispersed through the collecting groove 403 and the inclined surface 404, so that the polyurethane particles can fully contact the dry air.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
