Description

Technical Field

[0001] This utility model relates to the field of airflow dyeing machines, and more particularly to a gas-liquid mixing nozzle for an airflow dyeing machine. Background Technology

[0002] Airflow dyeing machines are advanced dyeing equipment that uses high-speed airflow instead of water baths. A fan suspends and circulates the fabric, simultaneously delivering atomized dye evenly into the fibers. Its core advantages include water conservation and environmental friendliness (liquor ratio as low as 1:2 to 1:3), high efficiency and energy saving (energy consumption reduced by 30% to 50%), low-tension dyeing (suitable for sensitive fabrics), and excellent evenness. Compared to traditional dyeing machines, it significantly reduces water consumption, shortens the dyeing cycle, and reduces fabric damage, making it particularly suitable for highly elastic or easily deformable fabrics such as polyester and nylon.

[0003] The nozzle of an airflow dyeing machine is a core component, responsible for atomizing the dye solution and precisely spraying it onto the fabric surface. High-pressure or high-speed airflow breaks the liquid dye into micron-sized droplets (typically 10–100 μm), ensuring that the dye uniformly covers the fibers in extremely fine particle form.

[0004] In existing technologies, the nozzles of airflow dyeing machines typically have an internal vortex chamber. When liquid passes through the vortex chamber, it is either refined into liquid particles or the liquid particles are atomized before being sprayed out through the nozzle. However, in practical applications, due to the different characteristics of different dyes, such as some high-viscosity dyes or liquids that are prone to agglomeration, the atomization effect of the vortex chamber alone is not good. There are problems such as poor breakage of some liquid particles and low gas-liquid mixing efficiency, which leads to defects such as color spots during dyeing.

[0005] Therefore, it is necessary to provide a gas-liquid mixing nozzle for an airflow dyeing machine to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a gas-liquid mixing nozzle for an airflow dyeing machine, which solves the problem that in some existing airflow dyeing machines, the nozzles have poor atomization and mixing of liquid and gas during use, which may lead to defects such as color spots during dyeing.

[0007] To solve the above-mentioned technical problems, this utility model provides a gas-liquid mixing nozzle for an airflow dyeing machine, comprising: a mixing chamber, an air inlet on the right side of the top of the mixing chamber, a liquid inlet on the right side of the mixing chamber, a support frame on the left side of the top of the inner wall of the mixing chamber, and rotating blades on the inner side of the support frame.

[0008] Preferably, an air intake ring groove is provided on the inner side of the mixing chamber, and six guide holes are connected to the left side of the air intake ring groove. The ends of the six guide holes that are close to each other are connected to the interior of the mixing chamber, and the bottom of the air inlet is connected to the top of the air intake ring groove.

[0009] Preferably, a liquid inlet connector is provided on the right side of the liquid inlet, a dispersing block is detachably provided on the right side of the liquid inlet connector, and a docking fixing member is provided on the right side of the dispersing block and outside the liquid inlet connector.

[0010] Preferably, a mixing tube is fixedly installed inside the mixing chamber and on the right side of the support frame. The connection between the right side of the mixing tube and the inner wall of the mixing chamber is a transition surface, and the mixing tube is smaller in the middle and larger at both ends.

[0011] Preferably, the left side of the mixing chamber is connected to a transition chamber, the inner side of the transition chamber is provided with a guide ring, the left side of the transition chamber is connected to a nozzle core, and the nozzle core and the outside of the transition chamber are provided with locking elements.

[0013] Compared with related technologies, the gas-liquid mixing nozzle of the airflow dyeing machine provided by this utility model has the following beneficial effects:

[0014] This invention provides a gas-liquid mixing nozzle for an airflow dyeing machine. By incorporating a dispersing block, it can disperse liquid clumps inside the mixing chamber before the liquid enters. Simultaneously, guide holes are provided in multiple directions within the mixing chamber to improve the mixing effect of gas and liquid. Finally, by incorporating a mixing tube and rotating blades, the gas-liquid two-phase flow is forcibly agitated, breaking up liquid clumps and forming initially mixed micro-droplets.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 A gas-liquid mixing nozzle for an airflow dyeing machine includes: a mixing chamber 1, an air inlet 2 on the right side of the top of the mixing chamber 1, a liquid inlet 3 on the right side of the mixing chamber 1, a support frame 4 on the left side of the top of the inner wall of the mixing chamber 1, and a rotating blade 5 on the inner side of the support frame 4.

[0021] By installing rotating blades 5 inside the mixing chamber 1, when external compressed air and liquid enter the mixing chamber 1, the liquid or gas impact will drive the rotating blades 5 to rotate at high speed. In turn, the rotating blades 5 will agitate and break up the liquid that subsequently passes through, forcibly agitate the gas-liquid two-phase flow, break up liquid clumps, and form initially mixed micro-droplets, which then enter the vortex chamber for further atomization, thereby reducing the atomization load of the subsequent vortex chamber and improving the final atomization uniformity.

[0022] An air intake ring groove 6 is provided on the inner side of the mixing chamber 1. Six guide holes 7 are connected to the left side of the air intake ring groove 6. The ends of the six guide holes 7 that are close to each other are connected to the interior of the mixing chamber 1. The bottom of the air intake port 2 is connected to the top of the air intake ring groove 6.

[0023] By introducing gas into the air inlet ring groove 6 and then discharging it into the mixing chamber 1 through each guide hole 7, since the guide holes 7 are set at an angle, when the liquid flows in the mixing chamber 1, the gas in each direction will mix with it, thereby initially improving the mixing efficiency and avoiding the problem of poor subsequent mixing effect.

[0024] A liquid inlet connector 31 is provided on the right side of the liquid inlet 3. A dispersing block 32 is detachably provided on the right side of the liquid inlet connector 31. A docking fixing member 33 is provided on the right side of the dispersing block 32 and outside the liquid inlet connector 31.

[0025] By incorporating a dispersing block 32, the liquid can be dispersed upon entry, preventing it from forming large clumps.

[0026] A mixing tube 8 is fixedly installed inside the mixing chamber 1 and on the right side of the support frame 4. The connection between the right side of the mixing tube 8 and the inner wall of the mixing chamber 1 is a transition surface. The mixing tube 8 is small in the middle and large at both ends.

[0027] By providing a mixing tube 8, both gas and liquid must pass through the narrowed channel in the center of the mixing tube 8, thus avoiding a large space where the gas is on top and the liquid is on the bottom.

[0028] The left side of the mixing chamber 1 is connected to the transition chamber 9. A guide ring 10 is provided on the inner side of the transition chamber 9. The left side of the transition chamber 9 is connected to the nozzle core 11. A locking element 12 is provided on the outside of the nozzle core 11 and the transition chamber 9.

[0029] The guide ring 10 has a tapered annular structure with a smooth inner wall that matches the inlet flow field of the vortex chamber. It can be made of silicon carbide ceramic, which resists dye corrosion and high fluid erosion.

[0030] The nozzle core 11 has a vortex chamber 13 inside, and the nozzle outlet 14 is located inside the nozzle core 11 and on the left side of the vortex chamber 13.

[0031] The end of the vortex chamber 13 that is connected to the nozzle 14 is an arc-shaped cavity, and the connection point between the vortex chamber 13 and the nozzle 14 is located at the top of the arc-shaped cavity.

[0032] The working principle of the gas-liquid mixing nozzle of the airflow dyeing machine provided by this utility model is as follows:

[0033] Step 1: When in use, liquid and gas are introduced into the corresponding interface through external equipment. When the liquid enters the mixing chamber 1, the dispersing block 32 can disperse larger liquid clumps and improve the subsequent mixing efficiency. At the same time, when the gas enters, the presence of various guide holes 7 and air inlet ring groove 6 allows the gas to mix with the liquid from different directions, improving the mixing effect.

[0034] Step 2: Under the continuous pressure of the external equipment, the gas and liquid will enter the gradually narrowing mixing tube 8 together. Since the center of the mixing tube 8 is small, the gas and liquid will be further mixed. Then, when the gas and liquid pass through the rotating blade 5, they will be driven to rotate at high speed. The rotating blade 5 will agitate and break up the liquid that passes through, forcibly agitate the gas-liquid two-phase flow, break up the liquid clumps, and form initially mixed tiny droplets, which then enter the vortex chamber for further atomization, thereby reducing the atomization load of the subsequent vortex chamber and improving the final atomization uniformity.

[0035] Compared with related technologies, the gas-liquid mixing nozzle of the airflow dyeing machine provided by this utility model has the following beneficial effects:

[0036] By incorporating a dispersing block 32, liquid clumps within the mixing chamber 1 can be dispersed before the liquid enters the mixing chamber 1. Simultaneously, guide holes 7 are provided in multiple directions within the mixing chamber 1 to improve the mixing effect of gas and liquid. Finally, by incorporating a mixing tube 8 and rotating blades 5, the gas-liquid two-phase flow is forcibly agitated, breaking up liquid clumps and forming initially mixed micro-droplets. These droplets then enter the vortex chamber for further atomization, thereby reducing the atomization load of the subsequent vortex chamber and improving the final atomization uniformity.

[0037] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
