Description

Technical Field

[0001] This utility model relates to the field of monofilament manufacturing equipment technology, and in particular to an energy-saving monofilament drying device. Background Technology

[0002] In the process of producing monofilaments (such as chemical fiber monofilaments, plastic monofilaments, etc.) in the factory, drying is usually required. In a few cases, due to residual moisture after the monofilament is formed (such as coating, washing), it may be necessary to perform secondary drying in subsequent processes. In this case, a channel-type monofilament drying equipment is required.

[0003] Existing monofilament drying equipment generates hot air through electric heating or steam heating. The hot air circulates in a closed space, contacts the surface of the monofilament, and removes moisture. It works in conjunction with the production line to achieve continuous drying. The monofilament is pulled through a narrow drying tunnel by guide rollers. Heating devices are installed in the drying tunnel, which is suitable for large-scale, continuous production.

[0004] However, this type of channel-type drying equipment relies on internal heating elements and fans to perform hot air drying on monofilaments, which results in high energy consumption and therefore needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an energy-saving monofilament drying device that can use the waste hot water in the workshop as the heat source of the drying equipment, and reuse it to save energy.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an energy-saving monofilament drying device, comprising a frame and an oven located on top of the frame. The oven has an inlet and an outlet on both sides, and guide roller mechanisms are also provided at the inlet and outlet for winding monofilaments through the oven. Inside the oven is a coiled, snake-shaped heat radiation tube, made of pure copper, with a wall thickness of 0.5mm-1.5mm and an inner diameter of 8mm-15mm. A water storage tank is located beside the frame, and a circulation pump is installed on top of the tank. The input end of the circulation pump is connected to the water storage tank via a pipe, and the output end is connected to one end of the heat radiation tube via another pipe.

When the operating temperature detected by the first temperature measuring device is less than the minimum threshold for drying, the control circuit controls the heating wire structure to start, so as to compensate for the temperature inside the oven cavity.

[0010] In a further technical solution, the water storage tank is also equipped with a wastewater inlet and a wastewater outlet for connecting to hot wastewater from the workshop. The wastewater inlet is equipped with a first electrically controlled valve, and the wastewater outlet is equipped with a second electrically controlled valve. The inside of the water storage tank is equipped with a second temperature detection device for detecting the water temperature inside the tank. The first electrically controlled valve, the second electrically controlled valve, and the second temperature detection device are electrically connected to the control circuit. When the water temperature detected by the second temperature detection device is lower than the set working water temperature, the control circuit controls the opening of the first and second electrically controlled valves to output low-temperature wastewater and input high-temperature wastewater. The working water temperature is set to be no less than 65°C.

[0011] In a further technical solution, the guide roller mechanism includes a roller support, a roller shaft, and multiple guide wheels. The surface of the roller shaft is smooth, and the roller shaft is rotatably mounted on both sides of the roller support. A through-hole is provided on the axis of the guide wheel, and each guide wheel is rotatably fitted onto the roller shaft through the through-hole. An isolation part is provided on both sides of the guide wheel, and the isolation part protrudes from the side of the guide wheel along the axis of the guide wheel. The isolation parts of two adjacent guide wheels are in movable contact with each other.

[0012] In a further technical solution, secondary wheels are formed on both sides of the guide wheel, and a single-wire guide groove is formed between the two secondary wheels. The bottom surface of the single-wire guide groove is arc-shaped, and the width of the single-wire guide groove is 0.3mm-1.5mm. Different guide wheels are provided with single-wire guide grooves of different widths. The outer surfaces of the secondary wheels on both sides are respectively formed with guide slopes that are inclined toward the single-wire guide groove.

[0013] In a further technical solution, the roller support has upwardly protruding support parts on both sides, and the support parts have upwardly opening forks; a limiting side cover is installed at each end of the roller shaft, the outer diameter of the limiting side cover is larger than the width of the fork, the two ends of the roller shaft are respectively movably engaged in the corresponding forks, and the limiting side covers on both sides are respectively matched with the limiting of the corresponding support parts.

[0014] In a further technical solution, a connecting hole is provided at the center of both end faces of the roller shaft, and the connecting hole is provided with an internal thread; a connecting rod is provided at the center of the inner side of the limiting side cover, and the connecting rod is provided with an external thread.

[0025] like Figures 1 to 4 As shown, an energy-saving monofilament drying device includes a frame 1 and an oven 2 located on top of the frame 1. The oven 2 has an inlet and an outlet on both sides, and guide roller mechanisms 5 are also provided at the inlet and outlet for winding monofilaments through the oven 2. Inside the oven 2, a coiled, snake-shaped heat radiation tube 6 is provided. The heat radiation tube 6 has a pure copper tube body, a wall thickness of 0.8 mm, and an inner diameter of 13 mm. A water storage tank 3 is located beside the frame 1, and a circulation pump device 4 is installed on top of the water storage tank 3.

[0026] Existing technologies do not utilize waste hot water as a heat source for monofilament drying devices. However, the monofilament drying device in this application is a low-temperature baking type, particularly suitable for using waste hot water as a baking heat source. The device innovatively uses hot wastewater from the workshop as the primary heat source, achieving secondary heat utilization through a circulation system of the heat radiation tube 6 and the water storage tank 3, reducing reliance on electric or steam heating and significantly lowering energy consumption.

When the water temperature detected by the second temperature detection device is lower than the set working water temperature, the control circuit controls the opening of the first electrically controlled valve and the second electrically controlled valve to output low-temperature wastewater and input high-temperature wastewater. The working water temperature is set to be no less than 65°C.

[0033] In addition, this application innovatively designs a modular guide wheel 53 to be suitable for drying monofilaments of different diameters. Specifically, the guide roller mechanism 5 includes a roller support 51, a roller shaft 52, and multiple guide wheels 53. The surface of the roller shaft 52 is smooth and is rotatably mounted on both sides of the roller support 51.

The isolation parts 532 of two adjacent guide wheels 53 are movable and abutting with each other.

[0034] Specifically, secondary wheels 531 are formed on both sides of the guide wheel 53, and a single-wire guide groove 5310 is formed between the two secondary wheels 531. The bottom surface of the single-wire guide groove 5310 is arc-shaped, and the width of the single-wire guide groove 5310 is 0.4mm.
