Description

Technical Field

[0001] This utility model relates to the field of chemical fiber spinning technology, specifically to a spinning and drying device for chemical fiber production. Background Technology

[0002] In chemical fiber spinning, the fiber-forming polymer is dissolved in a solvent to form a solution, or the fiber-forming polymer chips are heated and melted in a screw extruder to form a melt. After pre-spinning preparation, the melt is fed into a spinning machine. A spinning pump (metering pump) is used to press out the spinning solution or melt quantitatively, continuously, and uniformly from the fine orifice of the spinneret. This fine stream solidifies in water, coagulation liquid, or air to generate nascent fibers. This process is called fiber forming.

[0003] However, for the raw materials currently used in chemical fiber spinning, a crucial pretreatment step—drying—must be completed before further processing. The commonly used heating methods in this step have significant shortcomings.

[0004] Raw materials often accumulate inside the heating device, significantly reducing their mobility and causing compression. This results in uneven heating, which in turn reduces the efficiency of the drying process, leading to longer drying times and less than ideal drying results, failing to meet the production requirements of high-quality chemical fiber spinning. Therefore, a spinning drying device for chemical fiber production is proposed. Utility Model Content

[0005] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a spinning and drying device for chemical fiber production, capable of uniformly drying chemical fiber spinning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spinning and drying device for chemical fiber production, including a drying box, a feeding hopper at the top of the drying box, a partition fixed inside the drying box, and two sets of stepped lifting components capable of lifting materials at the top of the partition.

[0007] The stepped lifting assembly includes two sets of stepped frames mounted on the top of the partition. Each set of stepped frames has a baffle on its outer side. The outer wall of the baffle is provided with a guide plate connected to the inner wall of the drying chamber. Each set of stepped frames has multiple sets of single-step components. Each set of single-step components includes a fixed plate fixed to the top of the partition. One side of the fixed plate has a movable plate that extends through to the bottom of the partition. The bottom of the multiple sets of movable plates is connected to a connecting plate. A crankshaft capable of driving the movable plate to reciprocate and rise is rotatably provided inside the drying chamber.

[0008] As a preferred technical solution, the drying oven is equipped with a drive motor capable of driving the crankshaft to rotate, and the outer wall of the crankshaft is provided with a lifting arm connected to the bottom of the connecting plate.

[0009] As a preferred technical solution, the stepped lifting assembly further includes a rectangular frame positioned centrally between two sets of stepped frames, a rectangular groove for sliding of the rectangular frame is provided on the top of the partition, and a lifting arm connected to the rectangular frame is fitted on the outer wall of the crankshaft.

[0010] As a preferred technical solution, the ends of the two sets of guide plates abut against each other and are provided with constraint cones. The guide plates, drying box and baffles form a material return channel.

[0011] As a preferred technical solution, each set of moving plates is provided with a hot air pipe above it, and both ends of the multiple sets of hot air pipes are connected to a ventilation frame.

[0012] As a preferred technical solution, the top of the drying chamber is provided with a removable top cover, and the feed hopper is located on top of the top cover.

[0013] As a preferred technical solution, the front surface of the drying oven is provided with a material handling window, and the window is provided with a rotatable sealing plate.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention effectively avoids material accumulation inside the heating device by using a stepped lifting assembly, greatly enhancing the mobility between materials and reducing mutual pressure, thereby ensuring that the materials can be heated evenly. The crankshaft and lifting arm work together to drive the moving plates to rise back and forth, causing the materials on multiple moving plates to rise in an orderly manner. Combined with the material return channel formed by the guide plate, drying chamber, and baffles, a highly efficient material circulation system is formed, further improving drying efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A spinning and drying device for chemical fiber production, such as Figures 1 to 5 As shown, the equipment includes a drying chamber 100, a feeding hopper 120 on the top of the drying chamber 100, a partition 130 fixed inside the drying chamber 100, and two sets of stepped lifting components 200 on the top of the partition 130 that can lift materials.

[0026] The stepped lifting assembly 200 includes two sets of stepped frames 240 mounted on the top of the partition 130. Each set of stepped frames 240 has a baffle 230 on its outer side. The outer wall of the baffle 230 is provided with a guide plate 250 connected to the inner wall of the drying oven 100. Each set of stepped frames 240 has multiple sets of single-step components 241. Each set of single-step components 241 includes a fixed plate 242 fixed to the top of the partition 130. One side of the fixed plate 242 is provided with a movable plate 243 that extends through to the bottom of the partition 130. The bottom of the multiple sets of movable plates 243 is connected to a connecting plate 260. A crankshaft 140 is rotatably provided inside the drying oven 100, which can drive the movable plates 243 to reciprocate and rise.

[0027] The drying oven 100 is equipped with a drive motor 150 that can drive the crankshaft 140 to rotate. The outer wall of the crankshaft 140 is provided with a lifting arm 270 connected to the bottom of the connecting plate 260.

[0028] The step lifting assembly 200 also includes a rectangular frame 280 positioned centrally between two sets of step frames 240. The top of the partition 130 is provided with a rectangular groove 131 for sliding of the rectangular frame 280. The outer wall of the crankshaft 140 is fitted with a lifting arm 270 connected to the rectangular frame 280.

[0029] It is worth noting that the moving plate 243, together with the two adjacent fixed plates 242 and the baffle 230, forms a temporary storage slot, and the baffle 230 is U-shaped and sleeved on the outside of the stepped frame 240.

[0030] Both sets of stepped shelves 240 are tilted outwards;

[0031] The lifting arm 270 is movably sleeved on the outer wall of the crankshaft 140, and can intermittently lift the plate 243 as the crankshaft 140 rotates;

[0032] A long groove is provided at the position where the partition 130 contacts each set of moving plates 243, and the moving plates 243 can slide up and down in the long groove;

[0033] Each set of moving plates 243 is provided with a hot air pipe 220 above it. Both ends of the multiple sets of hot air pipes 220 are connected to a ventilation frame 210. The ventilation frame 210 is fixed to the bottom of the top cover 110 with bolts, and the outer wall of the hot air pipe 220 at the highest point is provided with a connecting pipe that penetrates to the top cover 110.

[0034] The raw materials for chemical fiber spinning enter the drying chamber 100 through the feed hopper 120. The raw materials fall onto the upper surface of the rectangular frame 280. At this time, the drive motor 150 starts, and its output end drives the crankshaft 140 to rotate. During the rotation of the crankshaft 140, the connecting plate 260 is driven to reciprocate up and down through the lifting arm 270. Due to the protrusion in the middle of the rectangular frame 280, the raw materials at the top slide to both sides when it rises, and then fall to the top of the lowest fixed plate 242 and the moving plate 243. As the crankshaft 140 rotates, the moving plate 243 rises, and the raw materials in the temporary storage tank are lifted to a higher position in a stepped manner. Then, under the action of gravity, they slide down the guide plate 250 to the next step frame 240, forming a stepped material conveying path.

[0035] Please refer to this carefully. Figure 1 and Figure 3 The ends of the two sets of guide plates 250 abut against each other and are provided with constraint cones 251. The constraint cones 251 guide the raw material on the guide plates 250 to the top of the rectangular frame 280. The guide plates 250, the drying box 100 and the baffle 230 form a material return channel.

[0036] The front surface of the drying oven 100 has a material loading window, and the window is equipped with a rotatable closing plate.

[0037] Meanwhile, the ventilation rack 210 evenly delivers hot air to the top of each moving plate 243 through the hot air pipe 220, dynamically heating the raw material during the sliding process; this ensures that the raw material is evenly heated during continuous turning, effectively avoiding the uneven heating problem caused by traditional stacking drying; after the raw material is circulated through the multi-stage step lifting component 200, it is finally collected through the material collection window on the front surface of the drying box 100, ensuring processing efficiency throughout the entire drying process.

[0038] Please refer to this carefully. Figure 1 and Figure 2 The top of the drying chamber 100 is provided with a removable top cover 110, and the feed hopper 120 is located on the top of the top cover 110;

[0039] The removable top cover 110 facilitates the cleaning and maintenance of the interior of the drying oven 100 in the future.
