Description

Technical Field

[0001] This utility model belongs to the field of polyamide fiber processing technology, and specifically relates to a drying device for polyamide fiber processing. Background Technology

[0002] Polyamide fiber is a synthetic fiber, with common varieties including nylon. It is a polymer synthesized from diamines and diacids through a polymerization reaction. Due to its excellent strength, elasticity, abrasion resistance, and chemical resistance, polyamide fiber is widely used in various textiles and industrial fields. The manufacturing of polyamide fiber begins with processing granular raw materials, followed by a series of processing steps to ultimately transform them into fiber form. During processing, the raw materials require drying to ensure the quality of the processed fiber, its performance, and the stability and durability of the final product.

[0003] In existing drying equipment, raw materials are usually piled up in one area when drying raw materials. Hot air is difficult to penetrate evenly into the entire pile of materials. Due to the possible existence of isolation layers between materials or uneven packing density, the propagation of hot air in the pile of materials is restricted, resulting in a large temperature difference between the surface and the interior of the material. This may cause some areas to overheat while other areas are under-dried, which in turn affects the drying effect of the raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for polyamide fiber processing, which enables material to be dried by flowing air and heating by hot air passing through the material layer. This makes the contact between heat and material more thorough and uniform, thereby improving drying efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A drying device for processing polyamide fibers includes a drying device shell, an inlet, and an outlet. The inlet is located on one side of the drying device shell, and the outlet is located on the other side of the drying device shell. The outlet is located at the bottom of the inlet. A drying auxiliary mechanism is provided inside the drying device shell. The drying auxiliary mechanism includes hot air blowers fixedly installed on both sides of the drying device shell. A first drying plate is fixedly connected to the inner wall of the drying device shell. A second drying plate and a third drying plate are provided at the bottom of the first drying plate. The second and third drying plates are evenly distributed vertically downwards. A baffle plate is installed on the top of each of the first, second, and third drying plates. There are several baffle plates, which are evenly arranged on the top of the first, second, and third drying plates. Each baffle plate is fixedly connected to the inner wall of the drying device shell. A backflow plate is fixedly connected to the inner wall of the drying device shell and is installed at an angle towards the outlet.

[0007] Preferably, inclined plates are fixedly connected to both sides of the inner wall of the drying device housing, a ventilation opening is provided at the top of the inclined plate, and a blower is fixedly installed at the bottom of the inclined plate. There are several blowers, which are evenly distributed at the bottom of the inclined plate.

[0008] Preferably, the top of the drying device housing is provided with a dehumidification port, and a dehumidification fan is fixedly installed on the top of the inner wall of the drying device housing, and the dehumidification fan is adapted to the dehumidification port.

[0009] Preferably, a baffle is fixedly installed on the top of the drying device housing, and the baffle is located on top of the dehumidification port.

[0010] Preferably, a shelf is installed on the inner wall of the drying device housing, the shelf is located inside the inclined plate, and the front hinge of the drying device housing is connected to the door panel, the shelf being adapted to the door panel.

[0011] Preferably, the inner walls of the inlet and outlet are hinged with partitions, and the partitions are made of stainless steel.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when drying raw materials, the raw materials are first added to the first drying plate inside the drying device housing through the feed inlet. Simultaneously, a hot air blower is operated, heating the interior of the drying device housing and increasing its internal temperature. Once the raw materials are on the first drying plate, they flow along the inclined direction of the plate. During this flow, the baffle plate ensures a slow and even flow, preventing excessive material density that would hinder the even penetration of hot air. After sliding down from the first drying plate, the raw materials slowly slide onto the second drying plate for even flow, and then onto the third drying plate for further drying. This even flow across the three drying plates ensures more thorough and uniform contact between heat and the raw materials, improving drying efficiency.

[0014] In this invention, a blower can be operated simultaneously when drying raw materials. The blower blows air upwards, which can effectively improve the airflow inside the drying device housing, help the hot air to be distributed more evenly on the material surface, enhance airflow to facilitate heat conduction, and allow the hot air to quickly contact the material surface, thereby accelerating the evaporation of moisture from the material and improving drying efficiency.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-3 As shown, a drying device for polyamide fiber processing includes a drying device housing 1, an inlet 101, and an outlet 102. The inlet 101 is located on one side of the drying device housing 1, and the outlet 102 is located on one side of the drying device housing 1, with the outlet 102 situated at the bottom of the inlet 101. A drying auxiliary mechanism is provided inside the drying device housing 1. The drying auxiliary mechanism includes hot air blowers 201 fixedly installed on both sides of the drying device housing 1. A first drying plate 202 is fixedly connected to the inner wall of the drying device housing 1. A second drying plate 203 and a third drying plate 204 are disposed at the bottom of the first drying plate 202. The second drying plate 203 and the third drying plate 204 are evenly distributed vertically downwards. A baffle plate 205 is installed on the top of the first drying plate 202, the second drying plate 203, and the third drying plate 204. There are several baffle plates 205, which are evenly distributed on the top of the first drying plate 202, the second drying plate 203, and the third drying plate 204. The baffle plates 205 are all fixedly connected to the inner wall of the drying device housing 1. A backflow plate 206 is fixedly connected to the inner wall of the drying device housing 1. The backflow plate 206 is installed at an angle towards the discharge port 102. With the cooperation of the drying auxiliary mechanism, the material can flow evenly during drying, so that the contact between heat and raw materials is more sufficient and uniform, preventing material accumulation from affecting the heat transfer, thereby effectively improving the drying efficiency of polyamide fiber raw materials.

[0022] like Figures 2-3As shown, inclined plates 301 are fixedly connected to both sides of the inner wall of the drying device housing 1. A vent 302 is provided at the top of the inclined plate 301, and a blower 303 is fixedly installed at the bottom of the inclined plate 301. There are several blowers 303, which are evenly distributed at the bottom of the inclined plate 301. While drying, the blowers 303 can be run and blow air upward through the vent 302. By pushing the airflow, the blowers 303 can increase the heat exchange rate, reduce the temperature difference between the material surface and the air, and allow the moisture to be quickly removed, thereby accelerating the drying process. This can significantly reduce drying time, save energy, and improve production efficiency.

[0023] like Figures 1-2 As shown, a dehumidification port 401 is provided at the top of the drying device shell 1, and a dehumidification fan 402 is fixedly installed on the top of the inner wall of the drying device shell 1. The dehumidification fan 402 is adapted to the dehumidification port 401. The dehumidification fan 402 can also be operated while drying. The operation of the dehumidification fan 402 can blow air upwards, which can effectively promote air flow and improve the convection of air inside the drying device shell 1, so that hot air and moisture can flow evenly. This can prevent moisture from accumulating in a certain position, thereby maintaining the uniformity of temperature distribution, avoiding local over-humidity or overheating, and ensuring that the material inside the entire drying device shell 1 is heated evenly.

[0024] like Figures 1-2 As shown, a baffle 403 is fixedly installed on the top of the drying device housing 1. The baffle 403 is located on top of the exhaust port 401. In some harsh environments, dust, debris, or external contaminants may exist around the exhaust port 401. The installation of the baffle 403 can effectively prevent these substances from entering the interior of the drying device housing 1 through the exhaust port 401, affecting the drying process or contaminating the materials. This can protect the internal cleanliness of the drying device housing 1 and reduce maintenance costs.

[0025] like Figure 2 As shown, a shelf 501 is installed on the inner wall of the drying device housing 1. The shelf 501 is located inside the inclined plate 301. The front hinge of the drying device housing 1 is connected to the door panel 502. The shelf 501 and the door panel 502 are adapted to each other. When the raw material is being dried in a flowing manner, small debris in the raw material will fall through the backflow plate 206 and be collected on the shelf 501. Thus, the debris inside the raw material can be collected in a concentrated manner under the action of the shelf 501. After collection, the door panel 502 can be opened, and then the debris collected on the shelf 501 can be collected and processed to prevent the debris from accumulating inside the drying device housing 1 and affecting its normal drying effect.

[0026] like Figures 1-2As shown, the inner walls of the feed inlet 101 and the discharge outlet 102 are hinged with partitions 6. The partitions 6 are made of stainless steel. Under the action of the partitions 6, the feed inlet 101 and the discharge outlet 102 can be dynamically blocked. During the drying process, by properly blocking, hot air can be prevented from easily escaping from these openings, which would lead to a decrease in thermal efficiency. By blocking the feed inlet 101 and the discharge outlet 102, the temperature inside the drying device shell 1 can be effectively maintained, heat loss can be reduced, and energy utilization efficiency can be improved.

[0027] The working principle of this utility model is as follows: When drying raw materials, the raw materials can be added to the first drying plate 202 inside the drying device housing 1 through the feed inlet 101. At the same time, the hot air blower 201 is running, which heats and blows air into the drying device housing 1, increasing the internal temperature. When the raw materials are on the first drying plate 202, they will flow along the inclined direction of the first drying plate 202. While flowing, the raw materials are blocked by the flow baffle 205, which makes the flow of the raw materials slow and uniform, preventing the raw materials from accumulating too densely and causing heat loss. Since air cannot penetrate the material evenly, when the raw material slides down from the first drying plate 202, it will slowly slide onto the second drying plate 203 for even flow, and then flow onto the third drying plate 204 for drying. This allows the raw material to flow evenly through the three drying plates, making the contact between heat and the raw material more sufficient and uniform, thus improving the drying efficiency. Finally, the dried raw material will slide down from the third drying plate 204 and flow onto the backflow plate 206. As the backflow plate 206 discharges outward from the discharge port 102, the uniform drying of the raw material is completed.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
