Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically to a stirring device for dyeing and flame retardant co-bath treatment. Background Technology

[0002] In textile finishing processes, dyeing and flame retardancy are two common and important steps. To achieve energy conservation, reduce consumption, and shorten the process flow, the technology of dyeing and flame retardancy in the same bath has emerged. This technology places higher demands on the processing equipment, especially the stirring system. The dyeing agent and flame retardant need to be uniformly dispersed in the dye bath and be able to efficiently and evenly contact and penetrate into the fabric.

[0003] Existing ordinary dyeing machine stirring devices are often single-function and cannot meet the precise control requirements of dyeing and flame retardant co-bath treatment. If the stirring is insufficient, it is easy to cause uneven distribution of dye and flame retardant, resulting in quality problems such as uneven fabric color and inconsistent flame retardant effect. If the stirring is too vigorous, it may damage the fabric surface or cause more foam, affecting the treatment effect. There is an urgent need to design a stirring device for dyeing and flame retardant co-bath treatment to solve the above problems. Utility Model Content

[0008] Furthermore, the bottom of the mixing tank is conical, and the multiple flat blades are shortened sequentially from top to bottom and correspond to the conical shape of the mixing tank. Multiple through holes are provided on one side of each flat blade.

[0019] like Figure 1-4 As shown in the figure, this utility model provides a stirring device for dyeing and flame retardant co-bath treatment.

[0020] The system includes a mixing tank 1, a main mixing shaft 2 rotatably fitted inside the top of the mixing tank 1, a secondary mixing shaft 3 rotatably fitted inside the bottom of the mixing tank 1, multiple propeller blades 4 inclined around the main mixing shaft 2, multiple flat blades 5 arranged around the secondary mixing shaft 3, a first motor 6 connected to the main mixing shaft 2 installed at the top of the mixing tank 1, and a second motor 7 connected to the secondary mixing shaft 3 installed at the bottom of the mixing tank 1. An adjustment mechanism 8 is provided between the main stirring shaft 2 and multiple propeller blades 4. A support frame 9 is installed on the outside of the stirring tank 1. Multiple circulation pipes 10 are provided on the outside of the stirring tank 1. One end of the circulation pipe 10 is connected to the bottom of the stirring tank 1, and the other end of the circulation pipe 10 passes through the outside of the stirring tank 1. A circulation pump 11 is provided at one end of the circulation pipe 10, and an output mechanism 12 is provided on the multiple circulation pipes 10.

[0021] Reference Figure 2In this embodiment, a support plate 13 is provided on the top of the mixing tank 1, and a first motor 6 is installed on the top of the support plate 13. Both sides of the support plate 13 are rotatably fitted with baffles 14, and the top of the baffles 14 is provided with a handle. The support plate 13 provides a certain range of support while working with the baffles 14 to cover the top of the mixing tank 1.

[0022] Reference Figure 2 In this embodiment, the output mechanism 12 includes a fixed ring pipe 15 disposed around the periphery of the mixing tank 1 and an output pipe 16 connected to the fixed ring pipe 15. The bottom of the fixed ring pipe 15 is provided with multiple connecting pipes connected to multiple circulation pipes 10, forming a three-way pipe with the circulation pipes 10. A three-way valve 17 is provided between the connecting pipes and the circulation pipes 10. A fixing clamp 18 is provided around the periphery of the mixing tank 1 to engage with the circulation pipes 10. The three-way valve 17 can be adjusted to control the flow direction of the slurry in the circulation pipes 10. Under normal circumstances, the slurry in the circulation pipes 10 will continuously flow into the mixing tank 1 for circulation and mixing. When it is necessary to discharge the mixed slurry, adjusting the three-way valve 17 allows the slurry in the circulation pipes 10 to enter the fixed ring pipe 15 and be transported outwards through the fixed ring pipe 15 and the output pipe 16.

[0023] Reference Figure 3 In this embodiment, the bottom of the mixing tank 1 is conical, and multiple flat blades 5 are successively shortened from top to bottom and correspond to the conical shape of the mixing tank 1. Multiple through holes 19 are provided on one side of the flat blades 5. Through the through holes 19, when the flat blades 5 are stirring the slurry, the slurry can pass through the through holes 19, so that the slurry forms a certain small vortex. The conical bottom allows the slurry to concentrate as it gradually descends, allowing the flat blades 5 to stir the slurry. At the same time, the circulating pump 11 can more easily extract the slurry.

[0024] Reference Figure 4 In this embodiment, the adjustment mechanism 8 includes a fixed plate 20 sleeved around the main stirring shaft 2 and multiple fixing bolts 21 disposed on the top of the fixed plate 20. One end of the propeller blade 4 is inclinedly disposed within the fixed plate 20, and the multiple fixing bolts 21 correspond to the multiple propeller blades 4 respectively. Through the fixed plate 20, the fixed end of the propeller blade 4 can be inserted into the fixed plate 20, so that the fixing bolts 21 fix one end of the propeller blade 4. When different fluid forces are required, propeller blades 4 with different tilt angles can be replaced as needed.

[0025] Reference Figure 4In this embodiment, a sealing bearing 22 is provided around the peripheral side of the auxiliary stirring shaft 3. The sealing bearing 22 is located at the bottom of the inner wall of the mixing tank 1, and a connecting bearing 23 is provided at one end of the main stirring shaft 2 to connect with one end of the auxiliary stirring shaft 3. The sealing bearing 22 can seal the connection between the auxiliary stirring shaft 3 and the bottom of the inner wall of the mixing tank 1, and the connecting bearing 23 can strengthen the connection between the main stirring shaft 2 and the auxiliary stirring shaft 3, resulting in higher stability without affecting the rotation speed and direction of the main stirring shaft 2 and the auxiliary stirring shaft 3.

[0026] Working principle: In use, firstly, add dye and flame retardant to the mixing tank 1, then start the circulation pump 11 to draw the dye liquid from the bottom of the mixing tank 1, allowing the dye liquid to pass through the circulation pipe 10 to one side of the mixing tank 1. The dye liquid will be sprayed into the mixing tank 1 in a tangential jet, forming an initial vortex. Then, start the first motor 6 and the second motor 7. The first motor 6 and the second motor 7 will drive the main stirring shaft 2 and the auxiliary stirring shaft 3 to rotate, respectively. When the main stirring shaft 2 rotates, it will drive multiple propeller blades 4, causing the propeller blades 4 to generate a downward axial thrust to drive the dye liquid to form a strong downward circulating flow. The auxiliary stirring shaft 3 will drive multiple flat blades 5 to rotate, causing the flat blades 5 to... The flowing dye liquor undergoes shearing and stirring to break up any agglomerated particles. Micro-vortices are generated through the through-holes 19 on the flat blades 5 to enhance mixing. The rotation direction and speed of the main stirring shaft 2 and the auxiliary stirring shaft 3 can be adjusted by controlling the first motor 6 and the second motor 7 as needed. The flow field state inside the mixing tank 1 can be precisely controlled to meet the mixing and circulation intensity requirements of each stage of the dyeing and flame retardant co-bath treatment. After the mixing is completed, the first motor 6 and the second motor 7 are stopped. After adjusting the three-way valve 17, the circulation pump 11 continuously draws the dye liquor from the mixing tank 1, allowing the circulation pipeline 10 to deliver the dye liquor to the fixed ring pipe 15. The dye liquor will be output to the outside through the fixed ring pipe 15 and the output pipe 16.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
