Description

Technical Field

[0001] The invention relates to the technical field of textile pulp preparation, and in particular to a preparation method of green and environmentally friendly modified textile pulp and a production device thereof. Background Art

[0002] Sizing is a critical process in textile weaving production. The sizing process is mainly aimed at the characteristics of warp yarns that are easy to pilling, easy to break, easy to generate static electricity, and not resistant to friction. Sizing is performed on them so that the yarns can withstand complex external mechanical forces during weaving. During the sizing process, on the one hand, the sizing liquid is coated on the surface of the yarn, and on the other hand, it penetrates into the inside of the yarn. After drying, a soft, tough, and elastic sizing film is formed on the surface of the sizing yarn, making the yarn smooth and the hairiness flat, and the bonding force inside the yarn and between fibers is enhanced. During the sizing process, the reasonable preparation and use of the sizing liquid plays a very important role in enhancing the wear resistance and elasticity of the yarn and improving the weavability of the yarn.

[0003] At present, in the formula of most textile slurries, PVA slurry and modified starch still account for the main body. However, PVA slurry has certain environmental pollution. Due to the increasing attention to environmental protection, not using or using less PVA has become the development direction of textile slurry. Although modified starch can meet the needs of hydrophilic fiber sizing to a certain extent, it is difficult to meet the sizing requirements of hydrophobic fibers. In fact, there are still many problems in the use of modified starch for sizing hydrophilic fiber yarns, such as: brittle film, small elongation at break, etc., and the existing reactor for preparing textile slurry itself does not have the function of filtering, resulting in the need to use a filtering device to filter the slurry after the preparation is completed, which not only reduces the production efficiency of the slurry but also increases the production cost. Therefore, in order to solve the above-mentioned existing problems, the inventors have developed a preparation method and a production device of a green and environmentally friendly modified textile slurry.

By providing the heat preservation sleeve, the air inlet pipe and the air outlet pipe, the kettle body can be heated, insulated and cooled, thereby improving the production efficiency, and the heat dissipation fins can improve the heat exchange effect of the air;

[0060] A slag discharge pipe 7 is connected to the bottom of the filter plate 3, and the slag discharge pipe 7 is located inside the discharge pipe 2. A blocking piece 8 that cooperates with the slag discharge pipe 7 is provided in the discharge pipe 2. When the filter plate 3 abuts against the bottom of the inner cavity of the kettle body 1, the top of the blocking piece 8 is flush with the top of the filter plate 3, and the blocking piece 8 includes a rubber blocking column 81 and a connecting rod 82. The rubber blocking column 81 is inserted into the inner wall of the slag discharge pipe 7, and the two ends of the connecting rod 82 are respectively connected to the rubber blocking column 81 and the inner wall of the discharge pipe 2. The rubber blocking column can play a role in sealing the slag discharge pipe to prevent the slurry from entering the slag discharge pipe during preparation.

[0061] The stirring rod 6 includes a connecting rod 61 and a connecting sleeve 62. One end of the connecting rod 61 is connected to the output end of the driving mechanism 4. The connecting sleeve 62 is sleeved on the outer wall of the other end of the connecting rod 61 and is slidably connected to the connecting rod 61. The outer wall of the connecting sleeve 62 is sleeved with a first rotating bearing seat 63. The side wall of the rotating bearing seat 63 is provided with a fixing rod 64. The fixing rod 64 is connected to the telescopic end of the electric cylinder 5. The outer wall of the connecting sleeve 62 is provided with a stirring blade 65. The bottom of the connecting sleeve 62 is rotatably connected to the filter plate 3. The telescopic movement of the electric cylinder drives the second rotating bearing seat to slide, thereby driving the connecting sleeve to slide along the connecting rod to realize the telescopic movement of the stirring rod. The side surface of the filter plate 3 close to the connecting sleeve 62 is provided with a mounting rod 31 at equal angles. The second rotating bearing seat 32 is connected between the ends of the four groups of mounting rods 31 close to each other, and the second rotating bearing seat 32 is sleeved on the outer wall of the connecting sleeve 62. This structure can not only ensure the relative rotation between the connecting sleeve and the filter plate, but also ensure that the filter plate can be driven to rise through the second rotating bearing seat when the connecting sleeve rises.

[0062] At the same time, the stirring blade 65 located at the bottom is in contact with the filter plate 3, and the stirring blade 65 is located between the mounting rods 31. By making the stirring blade in contact with the filter plate, the stirring blade can clean the surface of the filter plate when discharging slag, thereby preventing residue from remaining on the filter plate.

[0063] The working principle of the above reactor is as follows:

[0064] After the materials are sequentially added into the kettle body 1 through the feed pipe on the kettle body 1, the driving motor on the driving mechanism 4 is started to drive the connecting rod 61 and the connecting sleeve 62 to rotate (and in order to ensure that the connecting rod 61 can drive the connecting sleeve 62 to rotate, a sliding bar is provided on the outer wall of the connecting rod 61, and a sliding groove matching each other is provided on the inner wall of the connecting sleeve 62. The rotation of the connecting sleeve 62 drives the stirring blade 65 to rotate to stir the materials, so that the materials are mixed evenly to prepare the textile slurry, and during the material stirring process, the filter plate 3 abuts against the bottom of the inner cavity of the kettle body 1;

[0065] After the preparation of the textile slurry is completed, the electric cylinder 5 is started, and the electric cylinder 5 drives the connecting sleeve 62 to slide and shrink along the connecting rod 61 through the fixing rod 64 and the first rotating bearing seat 63, thereby driving the filter plate 3 to rise through the second bearing seat 32 and the mounting rod 31, and then the filter plate 3 is disengaged from the bottom of the inner cavity of the kettle body 1, so that the slurry can pass through the filter holes on the filter plate 3 and be discharged through the discharge pipe 2. At the same time, in order to prevent the slurry from accumulating in the slag discharge pipe 7, a filter hole is provided on the side wall of the slag discharge pipe 7, so that when the slag discharge pipe 7 rises with the filter plate 3, when the rubber plugging column 81 is immersed in the slag discharge pipe 7, part of the slurry flowing into the slag discharge pipe 7 can also be filtered, and in order to prevent the slurry from flowing out of the filter plate 3 when preparing the slurry, the filter plate 3 does not have a filter hole at the position corresponding to the discharge pipe 2;

[0066] After the slurry is discharged, the electric cylinder 5 is started to further drive the filter plate 3 to rise, so that the rubber blocking column 81 is completely separated from the slag discharge pipe 7, thereby opening the slag discharge pipe 7, so that the residue filtered on the filter plate 3 can be discharged from the slag discharge pipe 7, and the driving mechanism 4 drives the stirring blade 65 to rotate to clean the surface of the filter plate 3, further avoiding the accumulation of residue;

[0067] After the residue is cleaned, the filter plate 3 is lowered by the electric cylinder 5 so that the filter plate 3 abuts against the bottom of the kettle body 1, and the rubber plugging column 81 is reinserted into the slag discharge pipe 7 and flush with the top of the filter plate 3, and then the next preparation work is carried out.

[0068] In this embodiment, during the slurry preparation process, when the inside of the kettle body 1 needs to be heated, high-temperature gas is input into the insulation chamber through the air inlet pipe 11, so that the high-temperature gas heats the kettle body 1 and is then discharged from the air outlet pipe 11, and the heat dissipation fins 12 can improve the heat exchange effect. Similarly, when cooling is required, low-temperature gas is input into the insulation chamber to increase the cooling rate.
