Description

Technical Field

[0001] The utility model belongs to the technical field related to spinning and drying, and particularly relates to a novel superheated water insulation sleeve. Background Art

[0002] In the production process of continuous spun viscose fiber, the superheated water system is responsible for the drying process of the filaments. The difference in drying effect directly affects the forming of the bobbin, the dry stretching, dry strength and moisture regain of the filaments. Due to the high temperature of the superheated water, the service life of the contact accessories is affected, resulting in a high failure rate of the equipment. Therefore, extending the service life of the accessories and reducing the failure rate of the equipment are particularly important in ensuring and improving the spinnability of the machine. However, it still has the following disadvantages in actual use:

[0003] During the continuous spinning of viscose, hot water is directly passed through the drying shaft to heat the drying shaft. In order to better ensure the drying temperature, a heat preservation sleeve is inserted into the drying shaft to cooperate with water circulation. However, this modification causes direct contact between the superheated water and the drying shaft. The temperature of the drying shaft is high, and the inner sleeve of the heat preservation sleeve is heated inside and outside, which accelerates the aging process. At the same time, the reinforced polypropylene material of the inner sleeve is particularly severely aged.

[0004] During the continuous spinning and drying of viscose, superheated water needs to be circulated in the insulation casing. During the circulation process, the water delivery structure needs to cooperate with the water for transportation. During the operation, the water circulation delivery structure needs to rotate together with the drying shaft, which is easily damaged. Utility Model Content

[0008] Furthermore, one end of the inner sleeve close to the movable cavity is fixedly connected with a pressure pipe, and the pressure pipe is movably connected in the movable cavity. The inner sleeve is pressed into the movable cavity through the pressure pipe, so that the superheated water is transported to the inner sleeve.

An input hole is provided on the circumference of the thermal insulation outer tube at a position corresponding to the transfer cavity, and the input hole is connected to the transfer cavity.

During the conveying process through the water conveying pipe, the heat-insulating outer tube rotates as the drying shaft rotates, but the fixed cavity may not rotate as the heat-insulating outer tube rotates, thereby ensuring the stability of the water circulation. The water circulation conveying structure remains stable during operation and is not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-3 The utility model is a novel superheated water insulation sleeve, comprising an insulation outer tube 1, a fixed cavity 2 and an inner sleeve 3. A water delivery cavity 101 is provided at one end of the insulation outer tube 1. The insulation outer tube 1 is sleeved inside the drying shaft when working, and water is transferred through the water delivery cavity 101. The water to be transported is transferred through the water delivery cavity 101, and the heat of the hot water is transferred to the drying shaft through the insulation outer tube 1. An active cavity 103 is provided in the insulation outer tube 1 on the inner wall end face of the water delivery cavity 101. Water is transferred through the active cavity 103 to transfer heat. A central cavity 103 is provided in the insulation outer tube 1 on the side of the active cavity 103 away from the water delivery cavity 101. The transfer chamber 104 transfers the water input from the input hole 105 to the pressure pipe 301 through the transfer chamber 104. The outer side of the transfer chamber 104 is movably connected with a fixed chamber 2 around the insulation outer tube 1. The outer side of the water transfer chamber 101 is also movably connected with a fixed chamber 2 around the insulation outer tube 1. The water in the input insulation outer tube 1 and the output insulation outer tube 1 are transferred respectively through the two fixed chambers 2. The water transfer chamber 101 of the insulation outer tube 1 is provided with an inner sleeve 3. The heated water is transported through the inner sleeve 3. The diameter of the inner sleeve 3 is smaller than the inner diameter of the movable chamber 103, providing a transportation gap between the inner sleeve 3 and the outer sleeve for superheated water.

[0026] Specifically, one end of the inner sleeve 3 close to the active chamber 103 is fixedly connected to a pressure pipe 301, and the pressure pipe 301 is movably connected in the active chamber 103. When the inner sleeve 3 is working, it is movably connected in the active chamber 103 through the pressure pipe 301, so that when working, superheated water enters the transfer chamber 104 and is transported to the pressure pipe 301.

[0027] Furthermore, an output hole 106 is provided on the inner wall of the water transfer chamber 101 near the edge of the active chamber 103, and the output hole 106 is communicated with the water transfer chamber 101. An input hole 105 is provided on the inner wall of the water transfer chamber 101 at a position corresponding to the transfer chamber 104, and the input hole 105 is communicated with the transfer chamber 104. The output hole 106 and the input hole 105 are respectively arranged in two fixed chambers 2. The water transfer chamber 101 transfers water to the fixed chamber 2 through the output hole 106, transfers water in the fixed chamber 2 to the transfer chamber 104 through the input hole 105, and then transfers water to the pressure tube 301 through the transfer chamber 104.

[0028] Furthermore, the inner wall of the fixed cavity 2 is open, and sealing rings 201 are fixed at both ends of the fixed cavity 2. A fixing ring 202 is fixed on the inner wall of each sealing ring 201. The fixing ring 202 is fixed on the circumference of the thermal insulation outer tube 1, so that when working, the fixed cavity 2 is rotatably connected to the circumference of the thermal insulation outer tube 1.

[0029] The operation process of this embodiment is as follows: when working, water is first transported to the input hole 105 through the fixed cavity 2 outside the input hole 105, and after the water flows in the thermal insulation outer tube 1, it is transported to the output hole 106, and output to the fixed cavity 2 outside the output hole 106. During operation, when the input end and the output end of the external circulation heating water equipment are matched, the position of the delivery pipe 203 is changed by rotating the fixed cavity 2, and water is transported through the delivery pipe 203. During the transportation through the water delivery pipe, the thermal insulation outer tube 1 rotates with the rotation of the drying shaft, but the fixed cavity 2 may not rotate with the rotation of the thermal insulation outer tube 1, thereby ensuring the stability of the water circulation. Specific embodiment 2

[0030] See also Figure 1-5 On the basis of the specific embodiment 1, a delivery pipe 203 is fixedly connected to the peripheral side of the fixed cavity 2, and the end of the delivery pipe 203 away from the fixed cavity 2 is connected to the hard pipe of the external circulating heating water to stabilize the position of the fixed cavity 2. The end of the peripheral side of the inner sleeve 3 away from the pressure pipe 301 is provided with water outlet holes 302 in a circular array. The fixed cavity 2 transfers water through the delivery pipe 203, and the water transported in the inner sleeve 3 is transferred through the water outlet holes 302.

[0031] Specifically, a screw barrel 102 is fixed at the edge of one end of the water delivery cavity 101 in the thermal insulation outer tube 1 away from the active cavity 103, and a sealing cover 4 is connected to the screw barrel 102 through a thread. One end of the inner sleeve 3 away from the pressing tube 301 is movably connected in the screw barrel 102, and the sealing cover 4 and the screw barrel 102 abut against each other. The thermal insulation outer tube 1 is threadedly connected to the sealing cover 4 through the screw barrel 102 in the active cavity 103, and is pressed to the end of the inner sleeve 3 through the sealing cover 4, so that the pressing tube 301 on the inner sleeve 3 and the active cavity 103 are tightly pressed.

[0032] The operation process of this embodiment is as follows: when working, the superheated water is first transported to the input hole 105 through the fixed cavity 2, and then the water is transported to the transfer cavity 104. After the water is transported to the transfer cavity 104, it is transported to the pressure pipe 301, transported to the inner sleeve 3 through the pressure pipe 301, transported to the water outlet hole 302 through the inner sleeve 3, and transported to the gap between the inner sleeve 3 and the water delivery cavity 101 in the heat-insulating outer tube 1 through the water outlet hole 302. The heat of the superheated water is transferred to the heat-insulating outer tube 1, and is transferred to the drying shaft through the heat-insulating outer tube 1. After the water circulates, it is transported to the output hole 106, so that in the process of superheated water circulation, when passing through the gap between the inner sleeve 3 and the water delivery cavity 101 in the heat-insulating outer tube 1, the heat can be supplemented by heat exchange through the superheated water passing through the inner sleeve 3, thereby increasing the uniformity of the drying temperature.
