Device and process for washing carpets

Abstract

The invention relates to a device and a process for washing carpets in digital inkjet printing procedures. The device for washing the carpets comprises a paste recycling device, a washing tank, four guide rolls, a first water spraying device, a second water spraying device, a water flow flushing device and a vacuum water sucking device. The paste recycling device comprises two sucking barrels, a pumping pipeline, a vacuum pump, a filter device, a centrifugal water removing device and a mixing barrel; the washing tank is a trapezoidal tank with the length of 2 meters, the width of 4.3 meters and the depth of 1.3 meters, and the water flow flushing device and two guide rolls are mounted in the washing tank. The device and the method have the advantages that residual paste in the carpets can be thoroughly removed by the aid of the method, and accordingly the carpets are high in quality; water can be recycled in washing procedures, so that water resources can be saved; the paste can be recycled, so that the printing and dyeing waste water disposal difficulty can be lowered, and the benefit can be increased.

Description

technical field [0001] The invention belongs to the technical field of carpet printing production, and in particular relates to a carpet washing device and process in the process of digital inkjet printing. Background technique [0002] The production method of carpet digital jet printing is to spray the printing and dyeing slurry onto the white carpet to print and dye various colorful patterns. The products obtained by digital jet printing technology have rich patterns, bright colors, convenient pattern transformation, high production efficiency, and high production efficiency. The cost is low, so the digital jet printing carpet has been favored by many economical hotels as soon as it comes into the market. With the improvement of environmental protection awareness in the whole society, during the printing process, a certain amount of paste and additives are contained in the printing paste, and they enter the waste water together during washing. If the paste and additives ...

AI Technical Summary

Problems solved by technology

If the paste and additives in the carpet are not fully washed out, it will be difficult to dry the carpet in the subsequent sequence, and in the process of storage and transportation, there will be residual paste in the carpet, which is easy to breed bacteria, resulting in mildew and scrapping of the carpet

If the paste and additives are fully washed out, a large amount of water is required for washing, and the water consumption in the washing process reaches 6-8 tons / hour, the cost of water consumption is high, the pressure of sewage treatment is high, and the processing efficiency is low, time-consuming and labor-intensive
