Technical Field

[0001] This utility model relates to an integrated equipment for polypropylene fiber production. Background Technology

[0002] In the production process of polypropylene fiber, polypropylene granules need to be dried to improve the production quality of subsequent processes.

[0003] In existing technologies, large-scale dryers are used to dry polypropylene granules. Although this achieves the drying purpose, it requires a long waiting time, which affects the continuity of production and results in low work efficiency. Utility Model Content

[0006] The feeding assembly includes a feeding pipe, a guide pipe, and a spreading pipe. The feeding pipe is connected to the spreading pipe through the guide pipe. The feeding pipe is positioned above the spreading pipe. The guide pipe is arc-shaped. The horizontal height of the end of the feeding pipe away from the guide pipe is greater than the horizontal height of the end of the feeding pipe connected to the guide pipe.

[0007] The feeding assembly includes a feeding box and several guide plates disposed inside the feeding box. The spreading tube is horizontally disposed on the feeding box, and each guide plate is parallel and inclined. The end of each guide plate near the spreading tube is located below the spreading tube, and the side of the spreading tube near the guide plate is provided with a through hole.

[0008] The drying assembly includes a drying chamber, which contains a plurality of filters. The number of filters is equal to and corresponds one-to-one with the number of guide plates. The filters are inclined in the opposite direction to the inclination of the guide plates. A blower is provided at one end of the drying chamber, and an air outlet is provided at the other end of the drying chamber. The blower, filters, and air outlet are located at the same horizontal height.

[0009] Preferably, the spacing between each guide plate is equal.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1 As shown, an integrated polypropylene fiber production equipment includes a drying mechanism, which comprises a feeding component, a discharging component, and a drying component, arranged sequentially from top to bottom.

[0019] The feeding assembly includes a feeding pipe 1, a guide pipe 2, and a spreading pipe 3. The feeding pipe 1 is connected to the spreading pipe 3 through the guide pipe 2. The feeding pipe 1 is positioned above the spreading pipe 3. The guide pipe 2 is arc-shaped. The horizontal height of the end of the feeding pipe 1 away from the guide pipe 2 is greater than the horizontal height of the end of the feeding pipe 1 connected to the guide pipe 2.

[0020] The feeding assembly includes a feeding box 4 and several guide plates 5 disposed in the feeding box 4. The spreading tube 3 is horizontally disposed on the feeding box 4, and each guide plate 5 is arranged in parallel. The guide plates 5 are inclined. The end of each guide plate 5 near the spreading tube 3 is located below the spreading tube 3. The side of the spreading tube 3 near the guide plate 5 is provided with a through hole.

[0021] In fact, the feed pipe 1 is tilted upwards so that after the material particles enter the feed pipe 1, they can fall smoothly under their own gravity and enter the distribution pipe 3 through the guide pipe 2. The guide pipe 2 is designed as an arc shape mainly to reduce the lateral space occupied by the equipment. When the material accelerates into the distribution pipe 3, it will rush forward a distance under the action of inertia, preventing the material from accumulating at the opening of the guide pipe 2 and affecting the feeding effect.

[0022] The material enters the discharge box 4 through the spreading pipe 3. The spreading pipe 3 actually expands the discharge range. After the material is ejected from the guide pipe 2, it enters the spreading pipe 3, and the material will form a distribution from near to far from the discharge port of the guide pipe 2, increasing the discharge range. This allows the material to enter between multiple guide plates 5, avoiding the material from crowding between the guide plates 5 that are close to the discharge port of the guide pipe 2, thus enabling the material to be fully diffused.

[0023] The drying assembly includes a drying chamber 6, which contains a plurality of filters 7. The number of filters 7 is equal to and corresponds one-to-one with the number of guide plates 5. The filters 7 are inclined, and the inclination direction of the filters 7 is opposite to that of the guide plates 5. A blower 8 is provided at one end of the drying chamber 6, and an air outlet 9 is provided at the other end of the drying chamber 6. The blower 8, filters 7 and air outlet 9 are located at the same horizontal height.

[0024] The diffused material enters the space between the guide plates 5. At this time, the blower 8 blows hot air through the material, passing through the filter screen 7, thus drying the material. The filter screen 7 not only guides the hot air but also acts as a guide plate. As the material descends, it is dried by the hot air. After passing through multiple filters 7, the hot air is blown out from the air outlet 9. The isolation net 10 isolates the material to prevent it from being carried out by the airflow.

[0025] Preferably, the spacing between each guide plate 5 is equal.

[0026] Preferably, an intercepting net 10 is provided at the end of the air outlet 9 near the blower 8, and the mesh size of the intercepting net 10 is smaller than that of the filter 7.

[0027] Preferably, a receiving box 10 is connected to the bottom of the drying box 6, and the receiving box 10 is in communication with the drying box 6.

[0028] Preferably, in order to improve drying efficiency, the airflow introduced into the blower 8 is hot airflow.

[0029] Compared with existing technologies, this integrated polypropylene fiber production equipment enhances the inertial impact of particles by setting up a ramp feeding method, increasing the material travel distance and improving the uniformity of material drop. The material is then fed into the drying chamber 6 by the feeding component, where hot airflow blown by the blower 8 dries the material through airflow, achieving online drying and improving work efficiency.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
