Description

Technical Field

[0001] The utility model relates to the technical field of bleaching tanks, and more specifically to an environmentally friendly bleaching tank. Background Art

[0002] The main reason why fabrics need to be bleached is to remove impurities and pigments from the surface of the fabric, making it cleaner and brighter. Bleaching can make the fabric softer, smoother, and easier to absorb dyes or printing pigments. In addition, bleaching can also improve the durability and quality of fabrics, making them more durable and easy to maintain. The bleach in the bleaching tank can effectively remove stains, dirt and pigments from the fabric, making the fabric look cleaner and more beautiful. Therefore, bleaching is a very important step in the fabric processing process.

[0003] A Chinese patent (application number 2022220866859) discloses a bleaching device for gauze production, which includes a bleaching tank, a cleaning tank and a dewatering tank. The bleaching device performs water pressure treatment on the gauze through the cooperation between the upper squeezing roller 14 and the lower squeezing roller 15, but the squeezing dewatering effect is not good, and a lot of water will still remain on the gauze. Therefore, it is necessary to perform secondary dewatering on the cloth coming out of the dewatering tank and further improve the structure. Utility Model Content

[0004] The purpose of the utility model is to provide an environmentally friendly bleaching pool in order to solve the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] An environmentally friendly bleaching tank comprises a base, a bleaching tank, a cleaning tank and a water removal tank installed on the base, the cloth passes through the bleaching tank, the cleaning tank and the water removal tank in sequence, the bleaching tank also comprises a drying tank installed on the base, the cloth comes out from the outlet of the water removal tank and is movably connected to the inside of the drying tank;

[0007] A plurality of drying rollers are arranged inside the drying box, and the drying rollers are rotatably connected to the inner wall of the drying box. A hot air blower is arranged on the top of the drying box, and the air outlet of the hot air blower is connected to the inside of the drying box. A feed port and a discharge port are arranged on the left side of the drying box. After the cloth enters the feed port of the drying box, it rotates and connects along the drying rollers in sequence, and then comes out of the discharge port. The cloth in the drying box is dried by the hot air blower, and the water on the cloth evaporates to further remove water. The bleaching box, the cleaning box and the dewatering box in the utility model are all treated as the prior art. The inside of the bleaching box, the cleaning box and the dewatering box are all provided with an inlet and outlet adapted to the cloth. The cloth is bleached by the bleaching box, and then the bleached cloth is cleaned by the cleaning box. The cloth is preliminarily dewatered by the dewatering box. The drying box is mainly responsible for secondary dewatering of the cloth coming out of the dewatering tank.

[0008] The drying rollers are distributed in a V shape. In order to increase the residence time of the cloth in the drying box and improve the drying effect, the distribution of the drying rollers is designed to be V-shaped to increase the cloth's travel. The cloth's travel is increased, and the residence time increases at the same speed. In the utility model, the gap between the drying rollers will affect the drying effect of the cloth. If the gap is too small, it is not suitable for moisture volatilization. Therefore, after multiple simulation experiments, it was finally measured that the shortest distance between the two drying rollers cannot be less than 10 cm.

[0009] The top of the drying box is provided with a dehumidification port. By arranging the dehumidification port on the top of the drying box, the water vapor generated during the drying process can be effectively discharged, the inside of the drying box is kept dry, and the drying efficiency is improved.

[0010] The outer wall of the washing box is provided with a heating jacket, a heat pipe is provided between the heating jacket and the drying box, and a pressure relief hole is provided on the top of the heating jacket. The washing box is responsible for washing the fabrics. Washing can help remove residual bleach to avoid affecting subsequent dyeing, and the temperature of the clean water in the washing box will affect the washing effect of the fabrics, especially in winter, when the temperature of the clean water drops too quickly, resulting in poor washing effect of the fabrics that enter the site later. By providing a heat pipe to connect the heating jacket with the drying box, the residual heat in the drying box is passed into the heating jacket, the heating jacket is heated, and then the clean water is heated to avoid the clean water temperature being too low to affect the washing effect. The residual heat in the heating jacket is discharged through the pressure relief hole, and the residual heat in the drying box is used for heating and temperature increase, so that resources are reused and green and environmentally friendly.

[0011] The bleaching tank also includes a temperature sensor, a controller and a solenoid valve; the temperature sensor is installed on the inner wall of the washing box, the heat pipe is connected to an exhaust pipe, and the heat pipe and the exhaust pipe are both provided with the solenoid valve. The solenoid valve and the temperature sensor are both connected to the controller. The temperature of the clean water should not be too high. Too high a temperature will cause the fabric to harden and shrink, affecting the texture of the fabric. The optimal temperature of the clean water is about 30°C. The temperature sensor is used to monitor the temperature in the washing box and transmit the signal to the controller. When the monitored temperature reaches the preset temperature value, the controller issues a command to control the solenoid valve on the heat pipe to close, and at the same time controls the solenoid valve on the exhaust pipe to open. The residual heat in the drying box is discharged through the exhaust pipe to prevent the washing box from continuing to heat up.

[0012] The left side of the base is rotatably connected to a feeding roller, and the right side of the base is rotatably connected to a receiving roller; the left side of the bleaching box and the right side of the drying box are both rotatably connected to cloth guide rollers. Under the rotation of the receiving roller, the cloth passes through the cloth guide roller, the bleaching box, the cleaning box, the dewatering box, the drying box and the cloth guide roller in sequence from the feeding roller, and finally returns to the receiving roller.

[0013] The beneficial effects of the utility model are as follows:

[0014] The drying box is set up to remove water from the fabric for the second time to improve the water removal effect. The distribution design of the drying rollers is V-shaped to increase the fabric's passing stroke and increase the fabric's residence time in the drying box to improve the drying effect.
