Description

Technical Field

[0001] The invention belongs to the field of textile dyeing, and in particular relates to a hot water circulation system for dyeing water. Background Art

[0002] In the process of textile fabric processing, it is usually necessary to dye the produced fabric. Dyeing refers to dyeing, also known as coloring, which is to use chemical or other methods to affect the material itself to make it colored. When dyeing, the equipment usually used is the dyeing machine, but the existing technology has the following deficiencies:

[0003] In the dyeing process of the dyeing machine, hot water is usually used for dyeing. Hot water can accelerate the dissolution and penetration of the dye, making it easier for the dye molecules to disperse in the water, so as to penetrate into the fabric fibers faster, thereby improving the dyeing effect. When dyeing the fabric in different seasons, the water temperature is different due to different temperatures, so the water temperature in the dyeing tank is also different. In the prior art, the hot water in the dyeing machine is usually replaced by direct discharge, which makes the energy cost high, and the hot water cannot be recycled. Reheating the hot water requires both steam energy consumption and the need to adjust the water temperature to the required temperature, which is time-consuming and laborious. When dyeing the fabric, most of the textile fabrics are directly placed in the dyeing tank of the dyeing machine, and the fabrics are soaked and dyed with the help of the dye in the dyeing tank. In the dyeing process, since the textile fabrics are easily stacked into a ball, the color difference between the outer and inner sides of the fabric occurs, resulting in uneven dyeing, which affects the quality of dyeing.

[0004] This application proposes a hot water circulation system for dyeing water to improve the above-mentioned defects. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hot water circulation system for dyeing water that can uniformly dye fabrics, maximize heat recovery of hot circulating water, reduce steam consumption, and make the water temperature as close as possible to the requirements of the dyeing process.

[0012] In a specific possible implementation mode, a plurality of rollers are arranged on the top of the sliding block, and a clamping block which can be movably engaged with the annular sliding rail is arranged between the plurality of rollers.

[0013] In a specific possible implementation manner, the fixing device includes an auxiliary motor, an extrusion mechanism and a placement rack, the top of the extrusion mechanism is equipped with an auxiliary motor connected to a slider, and the bottom of the extrusion mechanism is connected to the placement rack.

[0014] In a specific feasible implementation scheme, the extrusion mechanism includes a fixed shell, a ball screw, a movable seat, a connecting rod, a clamping rod and an extrusion block. A ball screw is provided at the center of the fixed shell. The ball screw is slidably fitted with a movable seat by means of a guide.

The other ends of the plurality of connecting rods are rotatably fitted with the clamping rod. One end of the clamping rod is connected to the fixed shell.

[0046] See also Figure 7-Figure 8 The ball screw 52 is driven to rotate by the auxiliary motor 31, and the rotational motion is converted into linear motion with the help of the guide member in the moving seat 53, so that the moving seat 53 can slide on the screw and drive the connecting rod 54 connected thereto to move together, so that the clamping rod 55 is pushed by the connecting rod 54 to perform a clamping motion, which can squeeze the dyed fabric ball on the placement rack 33, so that the dyeing liquid on the fabric ball is discharged and falls into the dyeing pool 2 at the bottom for recovery, avoiding waste caused by the slipping of the dyeing liquid when the fabric ball is discharged after dyeing.

[0047] See also Fig. 9 The placement rack 33 includes a clearance groove 61, a slide groove 62, an arc-shaped protrusion 63 and a limit plate 64.

[0049] Based on the above embodiment, the specific working principle is as follows:

[0050] When the textile fabric is being dyed, the processing personnel sequentially place the textile fabric to be dyed on the placement rack 33, and then sequentially pull down the limiting plate 64 on the placement rack 33 to limit the fabric by the limiting plate 64 to prevent the fabric from falling off in the dyeing tank 2;

[0051] After the fabric is fixed, the driving motor 42 drives the first gear 411 to rotate, and drives the chain 413 to move by meshing with the chain 413 so that the second gear 412 can rotate synchronously, driving the plurality of groups of sliders 415 on the chain 413 and the annular slide rail 414 to move until the placement rack 33 with the fabric installed is located right above the dyeing tank 2 and stops, and then the cylinder 5 provided on the mounting rack 3 is operated to drive the placement rack 33 to descend until the fabric is immersed in the dyeing liquid for dyeing processing;

[0052] At the same time, when the convex rotating rod 12 is driven to rotate by the reduction motor group 11, the convex part on the convex rotating rod 12 can make a convex eccentric movement, thereby driving the connecting piece 13 and the dyeing pool 2 that are rotated together with the convex rotating rod 12 to swing back and forth along with the rotation of the convex rotating rod 12, so that the dyeing liquid inside the dyeing pool 2 will flow, thereby uniformly dyeing the textile fabrics immersed in the pool;

[0053] After the dyeing of the fabric is completed, the placement rack 33 is driven to rise and leave the dyeing tank 2 by means of the cylinder 5, and then the ball screw 52 is driven to rotate by the auxiliary motor 31, driving the moving seat 53 to slide on the screw, and driving the connecting rod 54 connected thereto to move together, and the connecting rod 54 is used to push a plurality of clamping rods 55 to perform a clamping movement, so that the dyed fabric balls on the placement rack 33 can be squeezed, so that the dyeing liquid on the fabric balls is discharged and falls into the dyeing tank 2 at the bottom for recovery, so as to avoid waste caused by the slipping of the dyeing liquid when the fabric balls are discharged after the dyeing is completed;

[0054] Then the motor 42 is driven to rotate the first gear 411, thereby driving the chain 413 and the plurality of sliders 415 on the annular slide rail 414 to move, and the dyed textile fabric is transported to the other side for unloading. At the same time, the new fabric is transported to the top of the dyeing tank 2 for the next round of dyeing, forming a reciprocating cycle.

[0057] See also Fig.10 The hot water pool, warm water pool and cold water pool can be controlled by the temperature range of hot water, producing a hot water pool of 65-70℃, a warm water pool of 47-53℃ and a cold water pool between 33-37℃. The hot water of about 70℃ can be used for washing the tank and post-processing of disperse dyeing; warm water of about 50℃ is used for dyeing disperse materials, cationic materials, acid post-processing, and soaping; the different needs of the process are utilized to the greatest extent; at the same time, through the existing dyeing controller, different water temperatures are used for cooling in the dyeing cooling stage, 135℃-100℃ cooling uses hot water of about 70℃, 100-80℃ uses warm water of about 50℃, and cooling water below 80℃ is used to avoid using cold water to cool the heat exchange high temperature, and the cooling rate fluctuates too much, and the hot water cut is recycled to the greatest extent.

[0058] See also Fig.10 The cold water pool is mainly composed of soft cold water produced. The pool can be heated to the set temperature range through the condensed water of the setting machine. When the water temperature is 50-55℃ and is higher than the overflow position of the pool, the water will be cooled to the cold water pool through the cooling water tower; if the pool temperature is too high, cold water will be added in time to ensure that it is maintained within the dynamic temperature control range.

[0059] See also Fig.10 The warm water pool is mainly dyeing cooling water. The pool can be heated to the set temperature range through the condensed water of the setting machine.
