Problems solved by technology

However, this equipment is a set of independent testing equipment. Although the testing process is fully automatic, the sample still needs to be weighed manually, which is only suitable for laboratory conditions and cannot realize online automatic testing in industrial production; The result is automatic control of the operation of the equipment

Embodiment 1

[0028] See figure 1 , The system of this embodiment has a dye liquor component adding device, a dye liquor reducing agent online detection device 5, a dye liquor pH online detection device 6, a dye liquor sampling pump 8 and a circuit device. The dye liquor component adding device has a dye liquor replenishing device 2 , a caustic soda replenishing device 3 and a hydrosulfite adding device 4 . The circuit arrangement has an industrial control computer 9 . The on-line detection and control system also has a material addition container 1 arranged in the dye liquor circulation loop of the dyeing machine.

[0029] 2, the industrial control computer 9 has a CPU board 91, an input board 92 and an output board 93 controlled by the CPU board 91, and also has an LCD display, a mouse, a keyboard, and a display card. The input board 92 is composed of an analog signal input sampling card 92-1 and a digital signal input card 92-2, and the output board 93 is composed of an analog and digi...

Embodiment 2

[0075] See Fig. 6 and Fig. 7, others are the same as embodiment 1, the difference is that: the online detection and control system of this embodiment is used in the ball warp dyeing machine. Therefore, compared with Embodiment 1, there are certain changes in the connection relationship of related equipment and components. Among them, the dye constant flow box 21 in the system is connected to the dye solution suction pipe 74 at the suction port of the dye solution circulation pump 71 through the filter, the dry vat dye solution supply metering pump 22 and the valve in sequence; the material addition container 1 is a material addition tank; The material adding tank 1 has a hydrosulfite adding port, a caustic soda solution adding port, a dye liquor output port and a dye liquor return port. The dye solution output port of the material adding tank 1 is connected with the dye solution circulating pump 71 through the valve, the dye solution suction pipe 74 and the filter screen succe...

Abstract

A detection and control system of dyeing liquid composition used on dyeing machine comprises addition unit of dyeing liquid composition, on - line detection unit of reducing agent and pH value for dyeing liquid, sampling pump and computer. It is featured as using potentiometric titration to detect reducing agent concentration in dyeing liquid and pH value of dyeing liquid on - line with set time, comparing obtained value with set value and controlling addition unit to add dyeing liquid according to compared result to keep dyeing liquid composition to be the same as set value for ensuring quality of dyeing.

Description

technical field [0001] The invention relates to a system for detecting and controlling the dye liquor components of a dyeing machine in textile printing and dyeing, and belongs to the field of dyeing textiles with vat dyes. Background technique [0002] The detection and control of traditional vat dyes in textile printing and dyeing basically adopt manual detection and manual control. In this control method, due to the long time interval of manual detection, the addition of dyes and auxiliaries varies from person to person, and the responsibility of the dyeing control personnel is different, human factors have a greater impact on the dyeing quality, and it is easy to cause The instability of various components of the dye solution in the dyeing tank, especially the color difference before and after dyeing. Therefore, ensuring the stability of various elements related to dyeing and reducing the influence of human factors has become the key to controlling color difference in d...
