Description

Technical Field

[0001] This application relates to the technical field of liquid stirring, and in particular to a dyeing liquid stirring device for an overflow dyeing machine. Background Technology

[0002] In the textile printing and dyeing industry, overflow dyeing machines are a commonly used dyeing equipment that plays a vital role in textile dyeing and processing. With the continuous development of the textile industry, the requirements for dyeing quality and efficiency are also increasing. Overflow dyeing machines can achieve uniform dyeing of textiles to a certain extent, improve dyeing effects, promote the development of the textile printing and dyeing industry, and enable the production of more high-quality dyed textiles, meeting market demands for textiles of different colors and qualities.

[0003] In traditional overflow dyeing machines, a stirring shaft and stirring paddle structure are usually used to agitate the dye liquor. The stirring shaft drives the stirring paddle to rotate, thereby agitating the dye liquor.

[0004] However, the dye solution tends to adhere to the inner wall of the tank and the surface of the stirring paddle during the stirring process. Traditional cleaning methods rely on manual scrubbing, which is not only time-consuming and labor-intensive, but also leaves many cleaning dead spots. The residual dye solution will contaminate subsequent batches of dye solution and affect the dyeing quality. Utility Model Content

[0005] In order to facilitate the cleaning of residual dye liquor and impurities, reduce cleaning dead spots, reduce the impact on the dyeing effect of subsequent batches of dye liquor, and improve the dyeing quality, this application provides a dye liquor stirring device for an overflow dyeing machine.

[0006] This application provides a dye liquor stirring device for an overflow dyeing machine, which adopts the following technical solution: it includes a dye liquor mixing tank, a stirring shaft and a stirring paddle are provided inside the dye liquor mixing tank, the stirring shaft is rotatably disposed inside the dye liquor mixing tank along the axial direction of the dye liquor mixing tank, the stirring paddle is radially disposed on the stirring shaft along the stirring shaft, and a cleaning nozzle is provided inside the dye liquor mixing tank, the cleaning nozzle is disposed towards the inner wall of the dye liquor mixing tank and the stirring paddle, and is used to rinse and clean the inner wall of the tank and the stirring paddle.

[0007] By adopting the above technical solution, the axial rotation of the stirring shaft and the radial arrangement of the stirring paddles achieve efficient mixing of the dye liquor, ensuring dyeing uniformity. At the same time, the cleaning nozzles are precisely oriented towards the inner wall of the tank and the stirring paddles, which can directly rinse away residual dye liquor and impurities, reduce cleaning dead corners, reduce the impact on the dyeing effect of subsequent batches of dye liquor, and improve dyeing quality.

[0008] Preferably, the dye mixing tank is provided with a planetary drive component, which drives the stirring shaft to rotate while simultaneously driving the cleaning nozzle to rotate.

[0009] By adopting the above technical solution, the planetary drive component synchronously drives the stirring shaft and the cleaning nozzle to rotate, eliminating the need for an additional drive structure and simplifying the overall layout of the device; the cleaning nozzle expands the rinsing coverage area as it rotates with the drive, making the cleaning of the tank wall and the stirring blade more comprehensive and thorough.

[0010] Preferably, the planetary drive component includes a sun gear and multiple planet gears. The multiple planet gears are distributed circumferentially around the sun gear and all mesh with the sun gear. The multiple planet gears are rotatably connected to the dye mixing tank. Multiple cleaning nozzles are provided. The multiple cleaning nozzles are coaxially connected to the multiple planet gears through bearings. One end of the sun gear is coaxially connected to a drive motor, and the other end of the sun gear is coaxially connected to the stirring shaft.

[0011] By adopting the above technical solution, the meshing structure of the sun gear, planetary gears and planetary orbits ensures that the rotation rhythm of the stirring shaft and the cleaning nozzles are matched in a coordinated manner, taking into account both the dye liquor mixing efficiency and the cleaning effect; multiple cleaning nozzles are coaxially connected to the planetary gears to achieve multi-directional synchronous rinsing, further improving the cleaning efficiency.

[0012] Preferably, the stirring paddle includes a stirring rod and a plurality of stirring blades. One end of the stirring rod is connected to the stirring shaft, and the other end of the stirring rod extends radially along the stirring shaft. The stirring blades are arranged radially along the stirring rod, and the plurality of stirring blades are arranged alternately along the axial direction of the stirring rod.

[0013] By adopting the above technical solution, the stirring blades are arranged in an alternating pattern along the stirring rod axis, breaking the inertia of the dye liquor flow, enhancing the turbulence effect of the dye liquor, and allowing the dye liquor to be mixed more thoroughly; the radial extension design of the stirring rod and stirring blades expands the stirring range, covers more areas in the dye liquor mixing tank, and improves the overall mixing uniformity.

[0014] Preferably, the top of the dye liquor mixing tank is connected to an inlet pipe, and a flow rod is also provided inside the dye liquor mixing tank. The flow rod is arranged along the axial direction of the dye liquor mixing tank and is connected to the inlet pipe. One end of the flow rod is rotatably connected to the top of the dye liquor mixing tank, and the other end of the flow rod is used to pass the dye liquor in the inlet pipe into the dye liquor mixing tank.

[0015] By adopting the above technical solution, the inlet pipe axially transports the dye liquor through the flow rod, avoiding the dye liquor from directly impacting local areas inside the tank and causing uneven mixing; the flow rod is rotatably connected to the top of the tank, and can adjust the conveying direction according to the flow of the dye liquor or external drive, so that the dye liquor is evenly dispersed to all parts of the tank, improving the initial mixing effect.

[0016] Preferably, the flow rod is provided with a plurality of fan blades at one end near the dye mixing tank, the fan blades are arranged radially along the flow rod, and the plurality of fan blades are arranged circumferentially along the flow rod.

[0017] By adopting the above technical solution, the fan blades at the end of the flow rod generate auxiliary stirring force as the dye liquor flows or rotates, enhancing the circulation effect of the dye liquor in the tank and accelerating the fusion of the newly injected dye liquor with the original dye liquor; the multiple fan blades are arranged circumferentially to further expand the coverage of auxiliary stirring and improve the mixing efficiency.

[0018] Preferably, a temporary storage tank is coaxially sleeved on the flow rod, one end of the liquid inlet pipe is connected to the top of the temporary storage tank, a flow channel is opened inside the flow rod, a flow opening is opened on the wall of the flow rod, the flow opening and the flow channel are connected, and the flow channel is used to lead to the dye liquor mixing tank.

[0019] By adopting the above technical solution, the temporary storage tank acts as a buffer for the dye liquor input through the inlet pipe, preventing excessively high local concentrations caused by excessively fast dye liquor injection speed; the flow channel and flow opening work together to realize the diversion and transportation of dye liquor, allowing the dye liquor to enter the tank in sections and evenly, ensuring mixing stability.

[0020] Preferably, a flow cavity is formed inside the fan blade, one end of which passes through the end of the fan blade away from the flow rod, and the flow cavity is connected to the flow channel.

[0021] By adopting the above technical solution, the flow chamber inside the fan blade transports the dye liquor to the far end of the fan blade and sprays it directly, so that the dye liquor can quickly spread to the edge area inside the tank and reduce the mixing blind zone; the flow chamber is connected to the flow channel to achieve auxiliary stirring and complete the effect of dye liquor dispersion, further improving the mixing uniformity and efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The staggered stirring blades of the agitator, combined with the dispersed spraying of the fan blades, work together to break up the layering of the dye liquor, avoid local concentration differences, and reduce color difference problems in fabric dyeing. 2. By using planetary drive components to achieve the linkage between stirring and cleaning, there is no need to configure an independent drive motor for the cleaning nozzle, which reduces energy consumption and achieves thorough cleaning. 3. The design of the temporary storage tank and flow channel buffers the impact of feeding, prevents dye liquor splashing and raw material waste, and the auxiliary stirring of the fan blades further improves the fusion speed of the feeding material and the original dye liquor in the tank.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application provides a dye liquor stirring device for an overflow dyeing machine, which facilitates the cleaning of residual dye liquor and impurities, reduces cleaning dead corners, minimizes the impact on the dyeing effect of subsequent batches of dye liquor, and improves dyeing quality.

[0027] refer to Figures 1-4 A dye liquor stirring device for an overflow dyeing machine includes a dye liquor mixing tank 110, which is cylindrical. A stirring shaft 120 and a stirring paddle 121 are disposed inside the dye liquor mixing tank 110. The stirring shaft 120 is rotatably disposed within the dye liquor mixing tank 110 along its axial direction. The stirring paddle 121 is radially disposed on the stirring shaft 120. A cleaning nozzle 130 is disposed inside the dye liquor mixing tank 110, facing the inner wall of the dye liquor mixing tank 110 and the stirring paddle 121, for rinsing and cleaning the inner wall of the tank and the stirring paddle 121. A planetary drive component 111 is mounted at the bottom of the dye liquor mixing tank 110 via a partition 117, and a drive motor is connected to one side of the planetary drive component 111. 15. On the other side, it is connected to the stirring shaft 120 and the cleaning nozzle 130 respectively. In this embodiment, the drive motor 115 is externally located at the bottom of the dye liquor mixing tank 110, and three stable support feet 116 are provided around the bottom of the dye liquor mixing tank 110. The stirring shaft 120 and the cleaning nozzle 130 are rotatably connected through the sealed bearing and the partition plate 117. The drive motor 115 drives the stirring shaft 120 to rotate and the cleaning nozzle 130 to rotate synchronously through the planetary drive component 111. This achieves efficient mixing of dye liquor and uniform dyeing. At the same time, the cleaning nozzle 130 is precisely oriented towards the inner wall of the tank and the stirring paddle 121, which can directly rinse away residual dye liquor and impurities, reduce cleaning dead corners, reduce the impact on the dyeing effect of subsequent batches of dye liquor, and improve the dyeing quality.

[0028] Specifically, the planetary drive component 111 includes a sun gear 112 and three planet gears 114. The three planet gears 114 are evenly distributed around the sun gear 112 and are rotatably connected to the central support column 113 and the partition plate via bearings. The lower end of the sun gear 112 is coaxially connected to the output shaft of the drive motor 115 via a coupling, and the upper end is welded and fixed to the bottom of the stirring shaft 120. A total of three cleaning nozzles 130 are provided. The three cleaning nozzles 130 are coaxially connected to the three planet gears 114 via rolling bearings. The nozzle outlets face the inner wall of the dye liquor mixing tank 110 and the stirring paddle 121. In this embodiment, a water tank 132 is also provided at the bottom of the dye liquor mixing tank 110. The three cleaning nozzles 130 are connected to the water tank 132 via three water pipes 131. The water pipes 131 and the partition plate 117 are rotatably connected via sealed bearings.

[0029] The stirring paddle 121 is provided in three sets. The three sets of stirring paddles 121 are distributed at equal angles along the circumference of the stirring shaft 120. Each set of stirring paddles 121 includes a stirring rod 122 and four stirring blades 123. One end of the stirring rod 122 is welded and fixed to the stirring shaft 120, and the other end extends horizontally along the radial direction of the stirring shaft 120. The four stirring blades 123 are arranged radially along the stirring rod 122, and adjacent stirring blades 123 are staggered at 45° along the axial direction of the stirring rod 122 to form a three-dimensional stirring structure, which can effectively break the inertia of the dye liquor flow.

[0030] In addition, the top of the dye liquor mixing tank 110 is connected to an inlet pipe 140. The dye liquor mixing tank 110 also includes a flow rod 142, a temporary storage tank 141, and three fan blades 143. One end of the inlet pipe 140 is connected to the top of the temporary storage tank 141, and the other end is used to connect to an external dye liquor supply system. The flow rod 142 is inserted axially at the center of the top of the dye liquor mixing tank 110, and one end of the flow rod 142 is rotatably connected to the top of the dye liquor mixing tank 110 via a sealed bearing. A rotary motor 118 is installed at the top of the dye liquor mixing tank 110, and one end of the flow rod 142 is coaxially connected to the output shaft of the rotary motor 118. The temporary storage tank 141 is cylindrical. The structure is coaxially sleeved on the upper part of the flow rod 142. The flow rod 142 has an axially penetrating flow channel 144 that runs through the bottom of the flow rod 142. Four flow openings 145 are evenly distributed circumferentially on the wall of the flow rod 142. The flow openings 145 are connected to the interior of the temporary storage tank 141 and the flow channel 144. Three fan blades 143 are evenly distributed circumferentially along the lower end of the flow rod 142. The fan blades 143 are perpendicularly welded to the flow rod 142. Each fan blade 143 has a flow cavity 146 inside. One end of the flow cavity 146 passes through the end of the fan blade 143 away from the flow rod 142, and the other end is connected to the flow channel 144, forming a diversion spray structure.

[0031] The implementation principle of the dye liquor stirring device of the overflow dyeing machine in this application embodiment is as follows: The drive motor 115 is started, and the drive motor 115 drives the sun gear 112 to rotate. The sun gear 112 simultaneously drives the stirring shaft 120 and three planetary gears 114 to rotate. The stirring shaft 120 drives three sets of stirring paddles 121 to rotate at high speed in the tank. The staggered stirring blades 123 form a three-dimensional stirring of the dye liquor, promoting the full fusion of dye and auxiliaries. At the same time, the external dye liquor enters the temporary storage tank 141 through the inlet pipe 140. After being buffered, it flows into the flow channel 144 through the flow opening 145. A part of the dye liquor is directly transported to the lower part of the tank along the flow channel 144, and another part is sprayed out from the far end of the fan blade 143 through the flow cavity 146 in the fan blade 143, so as to achieve uniform dispersion of the dye liquor. The flow rod 142 rotates synchronously under the action of the dye liquor impact and the stirring airflow, driving the fan blade 143 to perform auxiliary stirring, further improving the uniformity of dye liquor mixing.

[0032] During cleaning, high-pressure cleaning fluid is introduced into the cleaning nozzle 130. The planetary gear 114 rotates under the drive of the sun gear 112, which in turn drives the cleaning nozzle 130 to rotate, so that the nozzle forms a spiral rinsing trajectory. The high-pressure cleaning fluid is precisely sprayed through the nozzle onto the inner wall of the dye liquor mixing tank 110 and the surface of the stirring paddle 121, quickly removing the attached residual dye liquor and impurities. The cleaning wastewater is discharged through the drain pipe 119 at the bottom of the dye liquor mixing tank 110. All-round cleaning can be completed without manual intervention, which can directly rinse away residual dye liquor and impurities, reduce cleaning dead corners, reduce the impact on the dyeing effect of subsequent batches of dye liquor, and improve the dyeing quality.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
