A fully automatic printing water purification machine

Abstract

The invention relates to a full-automatic printing-water purification machine which comprises a water softening portion, a purification portion, a back pressure storage portion and an automatic constant-pressure water supply portion. The water softening portion comprises a resin softener, an automatic water-softening controller and a salt box connected with the automatic water-softening controller; the purification portion comprises a filter unit and a purification unit; the back pressure storage portion comprises a first storage tank and a second storage tank which are in parallel connection; the automatic constant-pressure water supply portion comprises a full-automatic self-sucking pump, and the water outlet of the full-automatic self-sucking pump is connected with a printing press. By the arrangement, printing water can be softened and purified, water purity is guaranteed, higher requirement on the printing water can be met, the machine is operated full-automatically, simple in operation, small in sizes and low in energy consumption, the printing water can reach ultrapure water level after treatment, various problems caused by water quality in printing can be solved, use cost of printing materials can be lowered, and printing quality is enabled to be more stable while color more colorful.

Description

technical field [0001] The invention relates to a printing water treatment device, in particular to a fully automatic printing water purification machine. Background technique [0002] At present, it is known that the only equipment used for printing water treatment is resin exchange water softening equipment. Using this method is only a simple softening of tap water, which cannot be purified and cannot be fully automatic for printing press water. The disadvantage of this kind of equipment is that after a certain period of time, it must be shut down to backwash and add salt to replace the reducing resin, which cannot guarantee the real-time water supply to the printing machine, cannot guarantee the purity of the supplied water, and cannot treat water other than calcium ions and magnesium ions. Other substances, unable to control the residual salt in the water after salt replacement, unable to ensure real-time constant pressure water supply, resulting in many problems caused ...

[0002] At present, it is known that the only equipment used for printing water treatment is resin exchange water softening equipment. Using this method is only a simple softening of tap water, which cannot be purified and cannot be fully automatic for printing press water.

The disadvantage of this kind of equipment is that after a certain period of time, it must be shut down to backwash and add salt to replace the reducing resin, which cannot guarantee the real-time water supply to the printing machine, cannot guarantee the purity of the supplied water, and cannot treat water other than calcium ions and magnesium ions. Other substances in the water cannot control the salt residue in the water after salt replacement, and cannot guarantee real-time constant pressure water supply, resulting in many problems caused by the unstable water quality of the printing machine
