Fountain solution filtering method and device for printing

Abstract

The invention relates to a filtration method for dampening solution used printing and a device thereof. By adopting the method, the dampening solution used for printing in an external circulation loop is inhaled mainly utilizing the pneumatic principles, and then the dampening solution is filtered by the corresponding filtration device for pneumatic dampening solution. The filtration device for the pneumatic dampening solution comprises a filter, a regulator and a shell, wherein, the filter is arranged on the shell, the regulator is arranged inside the shell, furthermore, the filter is connected with the regulator. Proved by long term experiments of researchers, the service life of the dampening solution which is filtered by the method of the invention is six times more than the service life of ordinary dampening solution which is not filtered. In addition, less chemical is used in the invention and exhaust emission and the cost of tail gas treatment is reduced greatly.

Description

technical field [0001] The invention relates to a method and device for filtering printing liquid, in particular to a method and device for filtering fountain solution for printing by using a pneumatic pump. Background technique [0002] With the continuous improvement of people's living standards, people are also pursuing spiritual needs while pursuing material, so various books, magazines and newspapers have appeared in society to meet people's spiritual needs. However, books The mass production of printed materials such as books, magazines and newspapers is inseparable from printing technology. In order to provide a large number of books, magazines and newspapers, etc., it is necessary to have better printing conditions and printing effects. [0003] In such a market with strict printing requirements, it is imperative to keep the printing machine working normally, but the fountain solution of the printing machine is one of the main factors affecting the working condition ...

AI Technical Summary

Problems solved by technology

[0005] First of all, as mentioned above, the existing printing machine will cause the stagnation of the machine due to the lack of its protection system, and after each machine stagnation, it takes a lot of time to replace the fountain solution. In today's huge demand, every little bit of time spent is wasting a lot of money. This is one of the main disadvantages of existing printing machines in the case of insufficient protection systems.

[0006] Secondly, as mentioned above, due to the lack of protection system of existing printing machines, the service life of fountain solution will be shortened, and the reduction of isopropanol will increase chemical substances and waste and pollute the environment. There is another disadvantage brought about by the printing machine in the case of insufficient protection system
