Description

Technical Field

[0001] This utility model relates to the technical field of humidity-controlled yarn drying device, and in particular to a humidity-controlled yarn drying device. Background Technology

[0002] The existing patent publication number (CN209588620U) discloses a yarn dryer, including a machine body and a conveying device. The machine body is provided with an inlet and an outlet. The conveying device includes a conveying track, a conveying roller mounted on the conveying track, and a driving device. The conveying roller can be driven by the driving device to move along the conveying track. The height of the inlet and outlet is greater than the diameter of the conveying roller but less than the height of the yarn loops hanging on the conveying roller. The conveying roller is parallel to the horizontal plane and the plane where the inlet is located, and can rotate along its own axis. An adjusting gear is installed on the conveying roller, and an adjusting rack parallel to the conveying track is installed at both the inlet and outlet. The adjusting gear can engage with the adjusting rack when it is about to pass the inlet or outlet. The yarn loops are fixedly mounted on the conveying roller. While ensuring the quality of the yarn loops, by designing the inlet and outlet to have a shorter height, the speed at which hot air dissipates from the machine body is reduced, thus saving production costs.

[0003] However, its control of drying humidity is not accurate enough. Since the time it enters the drying chamber each time is fixed, the drying temperature and air volume can only be adjusted based on experience. However, the error caused by this will increase due to the external temperature and humidity changes caused by the open port.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A humidity-controllable yarn drying device includes a non-standard support frame and a drying track frame designed to match the non-standard support frame. The drying track frame is equipped with a chain drive device for transmission, and a hanging bracket is provided on the chain drive device for hooking the yarn. The drying track frame forms a closed loop route.

[0006] It also includes an insulated evaporator, the walls of which are made of insulation material and surround a portion of the drying track frame. Heat drying and dehumidification are performed within the cavity formed by the insulated evaporator. It also includes a matching heat source for heat drying, and the heat source is connected to the inside of the insulated evaporator.

[0007] It further includes a detection unit which contains a humidity detector for on-line humidity detection of the hank yarn during the operation process, and the detection unit is located outside the heat preservation evaporation box. The advantage of this is to avoid the interference of the hot steam in the heat preservation evaporation box, making the actual humidity detection of the hank yarn more accurate.

[0008] Preferably, at least half of the travel of the drying rail rack is located outside the heat preservation evaporation box, and the two ends of the heat preservation evaporation box are respectively provided with a discharge port and a feed port. Under the drive of the chain drive device in the drying rail rack, the hank yarn enters the heat preservation evaporation box from the feed port and comes out through the discharge port and circulates. The detection unit is arranged on one side close to the feed port, thus leaving enough travel for the hot steam of the hank yarn to volatilize, which is convenient for reflecting its actual remaining humidity.

[0009] Preferably, the hot gas source includes a heating box and a hot drying fan supporting the heating box, and the hot gas source is arranged outside the heat preservation evaporation box.

[0010] Preferably, the hot gas source extends into the heat preservation evaporation box through a pipeline and forms a number of uniformly distributed exhaust ports in the heat preservation evaporation box.

[0011] The advantages and positive effects of the present utility model are:

[0012] 1. Compared with the existing drying system device, it can perform more accurate humidity control within a certain range and can be adjusted online without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] Combination Figure 1-2 A humidity-controllable yarn drying device includes a non-standard support 17 and a drying track frame 11 designed to be matched with the non-standard support 17. The drying track frame 11 is equipped with a chain drive device for transmission, and a hanging bracket is provided on the chain drive device for hooking the yarn. The drying track frame 11 forms a closed loop route.

[0020] It also includes an insulated evaporator 10, the wall of which is made of insulation material and surrounds a section of the drying track frame 11. Heat drying and dehumidification are performed in the cavity formed by the insulated evaporator 10. It also includes a matching heat source 18 for heat drying, and the heat source 18 is connected to the inside of the insulated evaporator 10.

[0021] It also includes a detection unit 14, which contains a humidity detector for online humidity detection of the yarn during operation. The detection unit 14 is located outside the heat-insulating evaporator 10. This has the advantage of avoiding interference from the hot steam inside the heat-insulating evaporator 10, making the actual humidity detection of the yarn more accurate.

[0022] Preferably, at least half of the travel of the drying track frame 11 is located outside the heat-insulating evaporator 10, and the heat-insulating evaporator 10 is provided with a discharge port 15 and a feed port 16 at both ends. Driven by the chain drive device in the drying track frame 11, the yarn enters the heat-insulating evaporator 10 through the feed port 16 and exits through the discharge port 15 and circulates. The detection unit 14 is located on the side close to the feed port 16, thereby leaving enough travel to facilitate the evaporation of hot steam from the yarn and to reflect its actual residual humidity.

[0023] Preferably, the heat source 18 includes a heating box 12 and a hot drying fan 13 that is matched with the heating box 12, and the heat source 18 is located outside the heat-insulating evaporation box 10.

[0024] Preferably, the heat source 18 extends into the heat-insulating evaporator 10 through a pipe and forms several evenly distributed exhaust ports inside the heat-insulating evaporator 10.

[0025] Preferably, in a specific embodiment, the humidity detector is a MODEL545 flue gas moisture and humidity meter provided by Qingdao Jingcheng Instrument Co., Ltd., which adopts the resistive-capacitive principle and is applicable to a temperature range of 0-190℃. During operation, a computer is also configured to control the operation and adjust the movement speed of the chain drive system in the drying track frame 11 according to the online humidity signal collected by the humidity detector. This allows for dynamic adjustment after each actual humidity detection, making the final humidity control more accurate and more scientific and efficient compared to traditional drying equipment.

[0026] It should be emphasized that the embodiments described in this utility model are illustrative and not limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation.
