Washing production line after printing and dyeing

Abstract

The invention provides a washing production line after printing and dyeing. The washing production line comprises wash water units, inter-box wringing devices as well as a fabric feeding device and a fabric discharge device which are distributed at the head and the tail of the production line respectively. The washing production line is characterized in that the production line is distributed in a U shape; and each wash water unit comprises a wash water groove, upper wringing rollers, lower wringing rollers, flow partition boards and cropping rollers, the upper wringing rollers and the lower wringing rollers are vertically opposite and located above isolation grooves, and are arranged in the length direction of the production line, the cropping rollers are located on the near sides of the lower wringing rollers, and each upper wringing roller is located above the corresponding isolation groove and can perform wringing movement of approaching and leaving the lower wringing rollers. With the adoption of the washing production line after printing and dyeing, the labor intensity of an operator can be reduced, a fabric is separated from a washing liquid after every time of cleaning and subjected to repeated wringing piece by piece, the cleaning gradient of the washing liquid is changed, and efficient, high-quality and environment-friendly production with low water and energy consumption is realized.

Description

technical field [0001] The invention relates to printing and dyeing equipment, in particular to a washing production line for washing after printing and dyeing. Background technique [0002] The printing and dyeing industry is an industry with a large amount of industrial water consumption and polluted wastewater discharge. It is one of the five key water engineering departments and a large sewage discharger after the power generation industry. my country is also one of the countries with serious water shortage and water pollution. Therefore, implementing clean production, saving water and reducing pollution is the only way for the sustainable development of my country's printing and dyeing industry. Compared with other printing and dyeing processes, the processing steps of washing water after printing are cumbersome and consume more water and heat. With the shortage of energy, the increase of prices, and the needs of environmental protection, the disadvantages of traditiona...

Problems solved by technology

Compared with other printing and dyeing processes, the processing steps of washing water after printing are cumbersome and consume more water and heat. With the shortage of energy, the increase of prices, and the needs of environmental protection, the disadvantages of traditional washing devices are more obvious. Change this status quo imperative

[0003] At present, the traditional washing production line after printing and dyeing is a straight line with a length of about 40 meters. The laborers have to go back and forth for inspection every 5 to 10 minutes, which is extremely labor intensive; There are a number of washing units and water squeezing devices between the tanks. The cloth feeding device and the cloth outlet device are respectively arranged at the head and tail of the production line. The water squeezing device between the tanks is located between the washing water units and is used to transfer The rope-shaped cloth is squeezed, and its washing unit has a washing tank; the lower part of the washing tank is provided with compartments through the partition, and the upper part of the washing tank is equipped with a cloth rolling roller that spans over each compartment. The shaft is installed on the front and rear end plates of the washing tank, and the front and rear end plates are respectively provided with a cloth inlet hole and a cloth outlet hole. The cloth roll rolls up the cloth strip from one compartment and falls into the next compartment, so that the cloth strip is continuously immersed in the compartment for washing, and then rolled out and dropped into the next compartment. In this way of washing water, the cloth strip will bring the liquid in the previous compartment to the next compartment, the concentration of the paste liquid is high, and sometimes the cloth strip will move forward directly on the cloth roll and fall into the compartment. The water immersion rate is not high, which makes it difficult to clean the cloth strips. To achieve the ideal cleaning effect, it is necessary to add more washing units, lengthen the production line, or increase the frequency of cleaning water renewal

Therefore, this traditional washing production line has the characteristics of high energy consumption, high water consumption, and high physical exertion of laborers.
