Description
Technical Field
[0001] This application relates to the technical field of polyester filament production and processing equipment, and in particular to a dust removal and drying device for polyester filament production. Background Art
[0002] Polyester filament, also known as polyester fiber, is a synthetic fiber made of polyethylene terephthalate (PET). Due to its high strength, good tensile resistance, wear resistance, colorfastness, and non-fading characteristics, it is widely used in many fields such as clothing, home textiles, industrial textiles, automotive interiors, ropes, fishing nets, and filtration materials.
[0003] Currently, during the production process of polyester filaments, they may absorb moisture in the air, leading to problems such as decreased fiber strength and moldiness due to excessive moisture; dust, impurities, and short fibers will adhere to the surface of the polyester filaments, and the impurities on the surface of the polyester filaments may wear the processing equipment during subsequent processing, reducing the cleanliness and quality of the polyester filaments. In order to facilitate subsequent processing and storage, it is a very necessary step to remove the residual impurity particles and moisture on the surface of the polyester filaments.
[0004] Existing polyester filament production equipment usually uses multiple layers of filter meshes to capture the fine dust on the surface of the filaments, and blows high-temperature air through the polyester filaments by a blower to quickly evaporate the moisture on their surfaces. Although this method can remove impurities and achieve the purpose of preliminary drying to a certain extent, many problems have also emerged in the actual application process. For example, the filter mesh is prone to clogging, resulting in a high maintenance frequency, and the direct contact between the high-temperature gas and the polyester filaments may damage their structure, thereby affecting the product quality.
[0005] First of all, the frequent replacement of the filter mesh increases the operating cost of the enterprise. Secondly, the problem that high-temperature air drying easily causes deformation or even breakage of the polyester filaments has not been effectively solved. This not only reduces the finished product rate but also limits the possibility of further improving production efficiency. Summary of the Utility Model
[0006] In order to improve the working efficiency of polyester filament drying and dust removal, this application provides a dust removal and drying device for polyester filament production.
[0007] The dust removal and drying device for polyester filament production provided by this application adopts the following technical solutions:
[0008] A dust removal and drying device for polyester filament production, including a chassis. Inside the chassis, a heat insulation plate is arranged horizontally. The heat insulation plate divides the chassis vertically into a drying chamber and a dust removal chamber. The drying chamber is located above the dust removal chamber. On the side walls of the drying chamber along both sides of the polyester filament conveying direction, a number of infrared heating tubes are evenly arranged. The dust removal chamber is distributed with a negative ion generation area and an electrostatic field area along the polyester filament conveying direction. Among them, a negative ion generator is arranged in the negative ion generation area, and an electrostatic dust collection component is arranged in the electrostatic field area. A feed port is opened on the chassis corresponding to the drying chamber, and a discharge port is opened on the chassis corresponding to the dust removal chamber. And the feed port and the discharge port are arranged on the same side wall of the chassis. A through hole for the polyester filament to pass through is vertically opened at the end of the heat insulation plate far from the feed port. At both corners of the chassis corresponding to the polyester filament conveying direction, a turning rod for the polyester filament to wind around is arranged. The axial directions of the two turning rods are parallel to the length direction of the through hole, and the three are in the same vertical direction.
[0009] By adopting the above technical solution, before using the dust removal and drying device to dry and remove dust from the polyester filament, the staff first pulls the polyester filament into the drying chamber from the feed port, then winds around the turning rod, turns and passes through the through hole, and then winds around the turning rod, turns and enters the negative ion generation area and the electrostatic field area of the dust removal chamber in sequence, and finally comes out from the discharge port. During the working process of the dust removal and drying device, the drying treatment is carried out first. The polyester filament is introduced into the closed infrared drying chamber and subjected to the action of mild and evenly distributed near-infrared spectrum radiation until it is fully dehydrated, which is convenient for subsequent processing and storage. The dust removal is carried out after drying. When the polyester filament passes through the negative ion generation area, it will be given a negative charge. As it continues to move forward to the electrostatic field area, due to the principle of like charges repelling and opposite charges attracting, the dust carrying negative charges will automatically adhere to the electrostatic dust collection component that has been subjected to positive polarization treatment, so as to separate from the surface of the polyester filament. This dust removal and drying device can efficiently remove the impurity particles and moisture on the surface of the polyester filament. Among them, the evenly arranged infrared heating tubes in the drying chamber can uniformly heat the polyester filament, so that the moisture evaporates quickly without damaging the structure of the polyester filament, avoiding the common deformation and fracture problems in the traditional high-temperature air drying method; the negative ion generator in the dust removal chamber generates particles with negative charges and adheres to the polyester filament after pretreatment, and the electrostatic dust collection device is arranged behind the negative ion generator, which can effectively adsorb the charged dust particles, improve the cleanliness of the polyester filament, and thus improve the quality of the polyester filament product.

The electrostatic dust collection assembly composed of the installation frame made of stainless steel and the dust collection plate made of aluminum can efficiently capture the impurities on the surface of the polyester filaments, improve the dust removal efficiency, and at the same time, the dust collection plate is easy to disassemble and clean, reducing the maintenance cost.
[0012] Optionally, a thermometer is provided in the drying chamber, and a controller is provided on the outer side wall of the chassis, and the thermometer is electrically connected to the controller.
[0013] By adopting the above technical solution, the operating temperature range of the drying chamber is controlled between 60°C and 80°C, which can effectively avoid thermal damage to the polyester filaments and ensure an ideal dehumidification effect. Therefore, the thermometer provided in the drying chamber can monitor the temperature change in the drying chamber in real time, ensure precise heating of the polyester filaments by the infrared heating tubes, and avoid damage to the polyester filaments caused by excessive temperature; the setting of the controller facilitates the operator to adjust the heating power according to the actual situation, maintaining the stability and controllability of the drying process, thereby improving the drying effect and production efficiency of the polyester filaments.
[0014] Optionally, a cover plate is detachably provided on one side of the chassis that commonly covers the drying chamber and the dust removal chamber.
[0015] By adopting the above technical solution, the detachably provided cover plate enables the operator to conveniently enter the interior of the chassis for maintenance operations such as cleaning and replacing parts, thereby ensuring the long-term stable operation of the device.

The inner opening space of the collection box matches the size of the through hole, and on both sides of the collection box along the length direction of the through hole, scraping plates are provided facing directly above the through hole.

The top ends of the two scraping plates are arranged oppositely for scraping short fibers and impurities from the polyester filaments.
[0017] By adopting the above technical solution, the setting of the scraping plates can effectively scrape short fibers and impurities from the surface of the polyester fibers, improving the cleanliness and quality of the polyester filaments and reducing the wear of subsequent processing equipment. At the same time, the impurities scraped by the scraping plates fall into the collection box along the inclined surface of the scraping plates, facilitating centralized treatment of the impurities and simplifying the subsequent maintenance process.
[0018] Optionally, limiting sliding grooves are provided on both sides of the top wall of the heat insulation plate along the length direction of the through hole. A limiting strip is slidably arranged in each limiting sliding groove. The limiting strip and the limiting sliding groove correspond to each other and are in sliding fit. The top walls of the two limiting strips are commonly connected to the bottom wall of the collection box.
[0019] By adopting the above technical solution, the design of the limit chute and the limit strip enables the collection box to be stably installed on the heat insulation board, and can be conveniently adjusted in position and disassembled, which helps to improve the convenience and working efficiency of cleaning the collection box.
[0020] Optionally, each of the steering rods is rotatably sleeved with a roller made of a flexible material.

The thermometer 42 is electrically connected to the controller 7.
[0037] Refer to Figure 1 and Figure 2 , In the dust removal chamber 5, a negative ion generation area 51 and an electrostatic field area 52 are distributed along the polyester filament conveying direction. A negative ion generator 511 is provided in the negative ion generation area 51. The negative ion generator 511 is fixedly provided on the top wall of the heat insulation plate 3 in the negative ion generation area 51 inside the chassis 1. An electrostatic dust collection assembly 8 is provided in the electrostatic field area 52.
[0038] Refer to Figure 1 and Figure 2 , During the operation of the dust removal and drying device, the polyester filament is introduced from the feed inlet 11 into the closed infrared drying chamber and subjected to the action of gentle and evenly distributed near-infrared spectrum radiation until it is fully dehydrated. Then the polyester filament winds around the turning rod 6, turns through the through hole 31, and then winds around the turning rod 6 and turns into the dust removal chamber 5. When the polyester filament passes through the negative ion generation area 51, it will be given a negative charge. As it continues to move forward in the moving direction and reaches the electrostatic field area 52, due to the principle of like charges repelling and opposite charges attracting, the dust carrying negative charges will automatically adhere to the electrostatic dust collection assembly 8 that has been positively polarized, thus separating from the surface of the polyester filament. Finally, the polyester filament that has completed dust removal and drying is output from the discharge outlet 12.
[0039] Refer to Figure 2, the electrostatic dust collection assembly 8 includes a mounting frame 81 and dust collection plates 82. The mounting frame 81 is made of stainless steel and is fixedly arranged on the side wall of the heat insulation plate 3 opposite to the chassis 1 in the electrostatic field area 52.

On the top wall of the heat insulation plate 3, limiting sliding grooves 32 are opened on both sides in the length direction of the through hole 31. A limiting strip 91 is slidably arranged in each limiting sliding groove 32. The limiting strip 91 corresponds to the limiting sliding groove 32 one by one and is in sliding fit. The top walls of the two limiting strips 91 are integrally formed on the bottom wall of the collection box 9 together.

The top ends of the two scraping plates 92 are arranged oppositely for scraping short fibers and impurities on the polyester filaments.
[0042] The implementation principle of the dust removal and drying device for polyester filament production in the embodiment of the present application is as follows: during the operation of the dust removal and drying device, the polyester filaments are introduced into the closed infrared drying chamber and subjected to the action of mild and uniformly distributed near-infrared spectral radiation until they are fully dehydrated;
[0043] Then the polyester filaments are wound around the steering rod 6 and turn to pass through the through hole 31, and while passing through the through hole 31, the short fibers and impurities on the polyester filaments are scraped off by the scraping plates 92. The scraped short fibers and impurities fall into the collection box 9 along the inclined surface of the scraping plates 92 and are subsequently centrally processed;
[0044] After passing through the through hole 31, the polyester filaments are wound around the steering rod 6 again and turn into the dust removal chamber 5. When the polyester filaments pass through the negative ion generation area 51, they will be given negative charges. As they continue to move forward in the moving direction and reach the electrostatic field area 52, due to the principle of like charges repelling and opposite charges attracting, the dust carrying negative charges will automatically adhere to the dust collection plates 82 that have been positively polarized, thus separating from the surface of the polyester filaments. Finally, the polyester filaments that have completed dust removal and drying are output from the discharge port 12.
