Abstract

The invention relates to a constant-pressure liquid supply device for spraying. The constant-pressure liquid supply device comprises a water tank, a spraying assembly, a first pressure tank, a secondpressure tank and an air inflating mechanism, the water tank, the air inflating mechanism and the spraying assembly communicate with the first pressure tank and are provided with a first conveying adjusting assembly used for adjusting the water conveying state, a first air inflation adjusting assembly used for adjusting the air inflation state and a first water outlet adjusting assembly used for adjusting the water outlet state respectively. The water tank, the air inflating mechanism and the spraying assembly are all communicated with the second pressure tank and are provided with a second conveying adjusting assembly used for adjusting the water conveying state, a second air inflation adjusting assembly used for adjusting the air inflation state and a second water outlet adjusting assembly used for adjusting the water outlet state respectively. By means of the arrangement, the constant-pressure liquid supply device can be used in cooperation with an original water tank of the printing machine, idle waste of resources is avoided, liquid can be quantitatively supplied to the printing machine according to use requirements, a large amount of printing waste water cannot be caused by quantitative liquid supply, and VOCs cannot volatilize due to the adoption of a totally-closed system.

Description

technical field [0001] The present application relates to the technical field of paper-making felts, and more specifically, to a constant-pressure liquid supply device for spraying. Background technique [0002] The water for the printing press is supplied through the circulation of the water tank and the water tank. Since the water tank of the printing machine is open during printing, a large amount of paper powder and paper scraps will fall into the water tank; the ink returned to the water tank caused by the rotation of the water bucket roller during printing will also pollute the printing water, so the water in the water tank must be Often replaced, resulting in a large amount of printing wastewater. Open sinks also volatilize a large amount of VOCs (generally referring to volatile organic compounds) into the air, causing air pollution. In order to solve this problem, the current printing machine can be changed to spray wetting method. The existing spray wetting needs ...
