Description

Technical Field

[0001] This invention relates to the technical field of yarn processing equipment, and in particular to the technical field of a yarn drying device. Background Technology

[0002] Yarn is a basic raw material in the textile industry. Before it can be used in textile processes, it needs to be processed, and one important step is yarn drying.

[0003] A yarn drying device with application (patent) number CN202320218658.4 includes a frame, a lid, a box body, and several driving mechanisms. The frame is provided with a lid and a box body that is slidably set and located inside the lid. The opening of the box body corresponds to the lid. The frame is provided with a driving mechanism that drives the box body to move away from and towards the lid. Several heating elements are provided inside the box body. The front and rear ends of the box body are respectively provided with a yarn inlet and a yarn outlet. Because the heat emitted by the heating elements is directly blown by several fans and flows inside the box body, the hot airflow is turbulent inside the box body and cannot achieve good circulation. The drying effect on the transmitted yarn is poor, and the hot airflow cannot contact the yarn evenly, resulting in poor yarn drying uniformity and affecting product quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a yarn drying device that can improve the uniformity of yarn drying and product quality, thereby enhancing market competitiveness.

[0005] To achieve the above objectives, the present invention proposes a yarn drying device, including an insulation box and a circulating heating mechanism.

A circulation channel is provided between the front end and / or rear end of the inner liner and the insulation box. The upper end of the insulation box contains motors arranged at intervals. The upper end of the inner liner contains air inlets corresponding to each motor. Each motor's rotating shaft is equipped with a fan impeller located inside the air inlet.

[0006] Preferably, the guide fluid is located above the heating tube, and the guide fluid and the heating tube are arranged in a row, with the guide fluid and the heating tube arranged perpendicularly to each other.

[0007] Preferably, the cross-section of the guide fluid is triangular, and the airflow channel between two adjacent guide fluids gradually narrows from top to bottom.

The upper part of the insulation box 1 is provided with the inner liner 21, the lower end of the inner liner 21 is open, and the inner liner 21 is provided with rows of guide tubes 25 and heating tubes 22. A circulation channel 3 is left between the front end and / or rear end of the inner liner 21 and the insulation box 1.

[0021] The cross-section of the guide fluid 25 is triangular, and the airflow channel 26 between two adjacent guide fluids 25 gradually narrows from top to bottom.

[0022] The circulation channel 3 is equipped with a mesh plate 4.

[0023] The lower part of the insulated box 1 is provided with a partition 5, and the partition 5 has a mesh hole 6 in the middle.

[0024] It also includes an exhaust fan 7, the input end of which is connected to the insulation box 1 below the partition 5 via a telescopic pipe, and the output end of which is connected to the discharge pipe.

[0025] It also includes a support 9, on which the insulated box 1 is slidably mounted. One side of the insulated box 1 is provided with a grooved yarn passage 8 located between the partition 5 and the inner liner 21. The support 9 is provided with a groove sealing plate 10 for sealing the groove of the grooved yarn passage 8. The support 9 is provided with two sealing plates 17 located at the two ends of the grooved yarn passage 8, respectively. Each sealing plate 17 is provided with a narrowing opening 18 corresponding to the grooved yarn passage 8. The area of ​​the narrowing opening 18 is smaller than the cross-sectional area of ​​the closed grooved yarn passage 8.

[0026] The support 9 is provided with two upper and lower guide rails 11 at both the front and rear ends. The insulation box 1 is provided with several guide rail wheels 12 that ride on the corresponding guide rails 11.

[0030] Working process of this invention: In the operation of the yarn drying device of the present invention, the motor 23 drives the fan impeller 24 to rotate. The airflow generated by the fan impeller 24 is evenly distributed through the rows of guide tubes 25 and heated by the heating tubes 22 before being blown onto the yarn passing through the trough-shaped yarn passage 8. Then, it enters the air inlet 26 through the circulation channel 3 (because when the fan impeller 24 rotates, it will draw the air in the heat preservation box 1 above the mesh plate 4 out of the air inlet 26, so that a negative pressure is formed inside the heat preservation box 1 above the mesh plate 4, so that the airflow in the trough-shaped yarn passage 8 can pass through the mesh plate 4 more smoothly into the heat preservation box 1 above). Under the action of the fan impeller 24, it is circulated again.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
