[0002] The sizing and dyeing combined machine includes sizing and dyeing functions, and is used in the pre-weaving process of the textile industry to complete the sizing and dyeing processes. It is also compatible with the matching requirements of shuttle and shuttleless looms, and can meet the sizing requirements of starch sizing, chemical sizing, and mixed sizing for warp yarns of pure cotton yarn, linen yarn, blended fabrics, chemical fibers and their blends.
[0003] During the sizing and dyeing process, a drying device is required to dry the sizing and dyed warp yarns. During this process, when the warp yarns come into contact with hot air, the water on them evaporates upwards under high temperature. This water vapor contains a large amount of heat energy, and its direct release causes significant energy loss, increasing the overall energy consumption of the drying process. Therefore, we propose an energy-saving and water-saving hot air drying device for sizing and dyeing to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-4 An energy-saving and water-saving hot air drying device for sizing and dyeing includes a drying box 1. The drying box 1 has symmetrically arranged strip-shaped inlets and outlets 2 at both ends. During use, warp yarns are fed into the drying box 1 through one inlet and outlet 2 and then out through the other inlet and outlet 2, allowing the sizing and dyeing warp yarns to pass through the drying box 1 for drying. In actual use, two parallel limiting shafts 16 are provided inside the inlet and outlet 2. The ends of the limiting shafts 16 are fixed to a fixed base, which is fixed to the drying box 1. The sizing and dyeing warp yarns pass between the two supporting shafts, thus supporting the warp yarns passing through the drying box 1.
[0025] like Figure 1 and Figure 2 As shown, a fixed frame 3 is provided at the bottom of the drying chamber 1. The fixed frame 3 is installed on the first support frame 4, and the first support frame 4 is fixed to the second support frame 5. The second support frame 5 is fixed to the bottom of the drying chamber 1. Several cross-flow fans 6 are installed at intervals at the bottom of the fixed frame 3. Multiple vents 17 are provided at intervals at the bottom of the drying chamber 1. Support legs 18 are installed at the bottom corners of the drying chamber 1. When the cross-flow fans 6 are operating, air outside the drying chamber 1 can be drawn into the drying chamber 1 through the vents 17 and transported upward by the cross-flow fans 6. Multiple support shafts 14 are provided at intervals inside the fixed frame 3. The ends of the support shafts 14 are fixed to the inner wall of the fixed frame 3. A second heating wire 15 is wound on the support shafts 14 to heat the upward-blown air, thereby drying the warp yarns passing through the drying chamber 1.
[0026] When the warp yarns are dried with hot air, the water remaining on the yarns will turn into steam after heating and rise upwards, such as... Figure 3 and Figure 4As shown, multiple heat-conducting pipes 7 are arranged at intervals above the fixed frame 3. The ends of the heat-conducting pipes 7 penetrate the fixed frame 3 and are connected to multi-port pipes 8. A "U"-shaped vent pipe 9 is arranged above the fixed frame 3. The ends of the vent pipe 9 are connected to the multi-port pipes 8 on both sides. Several air pumps 11 are arranged at intervals below the top of the vent pipe 9. A conduit 10 is installed at the outlet of the air pump 11. The other end of the conduit 10 is fixed to the vent pipe 9. The upward-flowing water vapor is drawn into the vent pipe 9 by the air pump 11 and sent to the heat-conducting pipes 7 by the vent pipe 9. Due to the thermal conductivity of the heat-conducting pipes 7, they can heat the air blown upward by the crossflow fan 6 together with the second heating wire 15. This allows the water vapor that is about to be discharged to be utilized and reduces the working power of the second heating wire 15, thereby achieving energy saving.
[0027] In order to reduce heat loss when water vapor is transported to the heat pipe 7, the vent pipe 9 is a heat-spreading pipe, and the first heating wire 12 is wound on the vent pipe 9 to heat the vent pipe 9, thereby preventing the water vapor from decreasing on its own.
[0028] Furthermore, such as Figure 2 and Figure 3 As shown, a gas collection hood 13 is provided at the top of the drying chamber 1, and the top of the gas collection hood 13 is fixed to the drying chamber 1 by a bracket. The inlet of the air pump 11 extends through the gas collection hood 13, which can limit and block the rising water vapor, and allow the water vapor to flow towards the air pump 11 under the operation of the air pump 11, so as to ensure the full collection of water vapor in the drying chamber 1.
[0029] To facilitate maintenance and repair of the internal facilities of the drying oven 1, an opening 19 is provided on one side of the drying oven 1, and a sealing door 20 is hinged to one side of the opening 19. The other side of the sealing door 20 is fixed to the drying oven 1 by a latch. A window 21 is provided on the sealing door 20, and a viewing glass is installed in the window 21 to facilitate observation of the interior of the drying oven 1 from the outside.
[0030] It should be noted that multiple temperature sensors are installed inside the drying chamber 1. These sensors are located on the inner wall of the fixed frame 3 and on the air vent 9, respectively. This allows for monitoring of the temperature of the hot air blown during drying and the temperature of the water vapor during transmission, ensuring the drying efficiency of the sized and dyed warp yarns. It should also be noted that a control cabinet is installed on the outer wall of the drying chamber 1. The control cabinet contains a controller, which is connected to the temperature sensors, the crossflow fan 6, the air pump 11, the first heating wire 12, and the second heating wire 15 via wires, enabling intelligent control of the drying process.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
