Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber production, and in particular to a chemical fiber vacuum drum. Background Technology

[0002] Currently, the main processes for preparing chemical fiber products include drying polyester materials, melt extrusion, high-precision filtration, spinning in a spinning box, and cooling and stretching. Among these, drying polyester materials is the most basic and important step.

[0003] In existing technologies, the drying of polyester chips is mainly accomplished by vacuum drum machines. Although existing vacuum drum machines have a large internal space and can load a large number of polyester chips at a time, during the rotation of the drum, some polyester materials agglomerate into clumps or gather in the corners of the drum, making it impossible to be heated and stirred evenly, thus reducing the overall drying effect. This leads to a decrease in the quality of the spinning process in the later stages, ultimately resulting in a reduction in the wear resistance of the finished product.

[0004] Therefore, there is an urgent need for a vacuum drum that can evenly stir and stir chemical fiber materials. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a chemical fiber vacuum drum with a clear structure, uniform stirring, and excellent drying effect.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0007] A chemical fiber vacuum drum includes: a rotating drum containing chemical fiber material, comprising a receiving cavity formed by a wall panel, a high-temperature pipe disposed within the wall panel, and an air outlet disposed on the wall panel and communicating with the high-temperature pipe. A set of support seats are disposed at both ends of the rotating drum to support its rotation; an air inlet device for conveying high-temperature steam into the high-temperature pipe, including an air inlet pipe communicating with the high-temperature pipe and a solenoid valve for controlling the amount of air entering the air inlet pipe; a vacuum pump device for evacuating the rotating drum, including a vacuum pipe extending from the outer side of the rotating drum away from the air inlet device into the receiving cavity and a vacuum pump communicating with the receiving cavity through the vacuum pipe; and a rotatable stirring section disposed within the receiving cavity to stir the chemical fiber material.

[0008] To achieve the above technical solution, a stirring section is installed inside the containment cavity to achieve uniform stirring and rapid drying of chemical fiber materials.

[0009] Furthermore, the stirring section includes a stirring rod extending approximately along the length of the drum and stirring blades continuously arranged in a spiral pattern around the outer circumference of the stirring rod.

[0010] To achieve the above technical solution, the stirring blades, which are continuously arranged in a spiral pattern along the length of the stirring rod, can effectively increase the contact area between the stirring part and the chemical fiber material, thereby improving the stirring efficiency.

[0011] Furthermore, the stirring blades have several through holes spaced apart from each other.

[0012] The above technical solution can effectively prevent the accumulation of chemical fiber materials on the mixing blades.

[0013] Furthermore, the stirring rod is a hollow cylinder with an air intake chamber inside, which is connected to the air intake pipe.

[0014] To achieve the above technical solution, the hollow air inlet cavity inside the stirring rod is used to increase the heat conduction area, reduce the heat conduction time, and improve the drying efficiency.

[0015] Furthermore, the outer surface of the drum is covered with an insulation layer.

[0016] Implementing the above technical solutions can effectively reduce heat loss, lower heating costs, and achieve cost reduction and efficiency improvement.

[0017] Furthermore, a filter screen is provided at one end of the vacuum line near the containment cavity; the diameter of the filter screen mesh is smaller than the diameter of the material.

[0018] The above technical solution prevents synthetic fiber materials from entering the vacuum pump through the vacuum pipeline, ensuring the stable operation of the vacuum pump.

[0019] Furthermore, the drum is equipped with material inlets and outlets.

[0020] As described above, the chemical fiber vacuum drum of this utility model has the following beneficial effects:

[0021] 1. In this application, by setting a stirring part extending along its own length in the drum, the heating, stirring and drying of the chemical fiber material are made more uniform, thereby improving the quality of the subsequent spinning.

[0022] 2. In this application, the cavity of the stirring rod is used to form an air intake chamber connected to the air intake pipe, which increases the heat conduction area and makes the chemical fiber material heat up faster and more evenly; at the same time, it reduces heat loss and improves the utilization rate of heat energy.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0027] Please see Figure 1-2 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0028] First embodiment:

[0029] Please see Figure 1 This utility model provides a chemical fiber vacuum drum 100, including a rotating drum 1 containing chemical fiber materials, a set of support seats 2 for supporting the rotating drum 1, and a stirring part 5 disposed inside the rotating drum 1. The rotating drum 1 is surrounded by continuously arranged wall panels 11, forming a receiving cavity 12 for containing the chemical fiber materials. High-temperature pipes 13 are arranged inside the wall panels 11 to heat the chemical fiber materials in the receiving cavity 12. Both ends of the rotating drum 1 are rotatably mounted on the support seats 2. The support seats 2 are provided with a drive unit 21 for driving the rotating drum 1 to rotate.

[0030] Specifically, the stirring rod 51 is positioned within the receiving cavity 12 approximately along the length of the drum 1.

[0031] Furthermore, it also includes an air intake device 3 for supplying high-temperature steam into the high-temperature pipe 13 and a vacuum pumping device 4 for evacuating the drum 1. The air intake device 3 includes an air intake pipe 31 connected to the high-temperature pipe 13 and a solenoid valve 32 for controlling the amount of high-temperature steam entering the air intake pipe 31. The vacuum pumping device 4 includes a vacuum pipe 41 extending from the outer side of the drum 1 away from the air intake device 3 into the receiving cavity 12 and a vacuum pump 42 connected to the drum 1 through the vacuum pipe 41. The air intake device 3 supplies high-temperature steam from the steam heating device along the air intake pipe 31 to the high-temperature pipe 13 in the wall panel 11. The heat is conducted into the receiving cavity 12. The stirring part 5 stirs and stirs the chemical fiber material in the rotating drum 1, making the chemical fiber material heat up faster and more evenly. The moisture in the chemical fiber material is evaporated into the receiving cavity 12 and finally extracted from the drum 1 by the vacuum pumping device 4.

[0032] Please continue to refer to the figure. The stirring part 5 includes a stirring rod 51 and stirring blades 52 disposed on the stirring rod 51.

[0033] The stirring rod 51 extends approximately along the length of the drum 1, with both ends rotatably mounted inside the drum 1. The stirring blades 52 are continuously arranged in a spiral pattern around the outer circumference of the stirring rod 51. Because the individual volume of the chemical fiber material is small, using the stirring rod inserted into the stirring rod 51 results in a small contact area between the stirring rod and the chemical fiber material, leading to poor stirring effect. Therefore, using the stirring blades 52 to stir the chemical fiber material increases the contact and stirring area, resulting in more uniform stirring and a better effect.

[0034] Furthermore, the stirring blade 52 is provided with several through holes 521 spaced apart from each other. Since the stirring blade 52 has a large surface area, chemical fiber materials may accumulate on the stirring blade 52. Therefore, by providing through holes 521 on the stirring blade 52, sufficient stirring area can be ensured while preventing the accumulation of chemical fiber materials on the stirring blade 52, resulting in more uniform stirring and frying, and better drying effect.

[0035] Preferably, one end of the stirring rod 51 is connected to a drive motor. By setting a drive motor at either end of the stirring rod 51, the stirring speed and direction of the stirring section 5 can be actively adjusted. Different stirring speeds or different stirring directions can be used to stir the chemical fiber material at different time periods, which can greatly improve the stirring efficiency.

[0036] Please continue reading. Figure 1 A filter screen 7 is provided at one end of the vacuum line 41 near the receiving cavity 12. The diameter of the mesh of the filter screen 7 is smaller than the diameter of a single chemical fiber material, effectively preventing the chemical fiber material from entering the vacuum pump 42 along with the vacuum line 41.

[0037] like Figure 1 and Figure 2As shown, the drum 1 also has a material inlet / outlet 15 and an air outlet 14 connected to the high-temperature pipe 13. When the material inlet / outlet 15 faces upward, it can be used for feeding the chemical fiber material to be dried; when the material inlet / outlet 15 faces downward, it is used to discharge the dried chemical fiber material from the drum 1. In addition, the material inlet / outlet 15 also functions as an inspection port, allowing technicians to enter the drum 1 through the material inlet / outlet 15 to inspect and maintain the drum 1.

[0038] Second embodiment:

[0039] Please see Figure 2 The stirring rod 51 is a hollow cylinder, and an air intake chamber 511 is formed inside it.

[0040] Specifically, the two ends of the air inlet chamber 511 are connected to the high-temperature pipe 13 and the air outlet 14, respectively, and the high-temperature steam conducts heat from the air inlet chamber 511 into the receiving chamber 12. The stirring rod 51 serves as the heat conduction medium in the receiving chamber 12, which has closer contact with the chemical fiber material, resulting in excellent and even heat conduction, improving the thermal energy utilization rate of the high-temperature steam, and at the same time, the chemical fiber material is heated more evenly.

[0041] Please continue reading. Figure 1 The outer circumference of the drum 1 is covered with an insulation layer 6. The insulation layer 6 can effectively prevent heat from the high-temperature pipe 13 from being transferred to the outer circumference of the drum 1, thereby improving the utilization efficiency of high-temperature steam and reducing heat loss.

[0042] One end of the outlet 14 is connected to the high-temperature pipeline 13 and the inlet chamber 511, and is used to discharge the steam after the heat energy in the high-temperature pipeline 13 and the inlet chamber 511 has been released; the other end of the outlet 14 is equipped with a gate valve 16, and the outlet gas 14 is connected to the recovery pipeline 8 through the gate valve 16. The other end of the recovery pipeline 8 is connected to a safety exhaust device. When the drum 1 is working, the gate valve 16 is in the closed state; when it is necessary to discharge steam, the recovery pipeline 8 is connected to the outlet 14 and the gate valve 16 is opened, so that the discharged steam enters the safety exhaust device along the recovery pipeline 8.

[0043] The implementation principle of the chemical fiber vacuum drum 100 in this utility model is as follows: When the chemical fiber material enters the drum 1, high-temperature and high-pressure gas enters the high-temperature pipe 13 and the air inlet chamber 511 of the stirring rod 51 inside the wall plate 11 through the air inlet pipe 31. The drum 1 starts to rotate under the drive of the drive unit 21. The chemical fiber material is stirred inside the drum 1 under the drive of the drum 1 and is stirred back and forth by the stirring rod 51 under the action of gravity. The chemical fiber material is heated, and the moisture contained therein is released into the receiving chamber 12 in the form of steam. After stirring for a certain period of time, the moisture in the chemical fiber material is basically discharged. At this time, the vacuum pump 42 quickly extracts the air filled with water vapor from the receiving chamber 12 to achieve the purpose of drying the chemical fiber material. The steam after the heat energy is released is discharged from the air outlet 14 and enters the safety exhaust device along the recovery pipe 8, while the dried chemical fiber material is discharged from the material inlet and outlet 15.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
