Problems solved by technology

[0002] The coating liquid must be prepared before the existing coating. Conventionally, various liquids of different components are mixed together for stirring, and the fully stirred coating liquid enters the downstream from the feeding pipeline for coating. The disadvantage is that due to The preparation of a variety of different materials, if not used up within the effective time, will produce changes in chemical properties, such as the preparation of PCB photosensitive film mixture, the viscosity will increase after a long time, and it will also produce sensitivity and fog. Changes, so this will affect the quality of downstream coating products, resulting in waste, which will increase production costs for enterprises

Embodiment Construction

[0008] The embodiment will be described in detail in conjunction with the above drawings. A precision gear metering pump 2, a mass flow meter 3 and a dynamic mixer 4 are arranged in sequence on the liquid tank 1. There are at least two precision gear metering pumps, and each precision gear metering pump The inlet of the metering pump is connected with a feed pipe, and the feed pipe 7 is connected with the raw material liquid tank, and the outlet of the precision gear metering pump is connected with the inlet of the mass flow meter 3 through the delivery pipeline 8. The flowmeter is connected to the controller, and the controller is connected to the control display 10 through a special cable 9 to form a closed-loop control. The control display is fixed on the wall above the mass flowmeter, and the outlet of the mass flowmeter is connected to the dynamic flow through the pipeline. The liquid inlet 5 on the mixer is connected, and the liquid outlet 6 on the dynamic mixer is connec...

Abstract

The invention discloses an online mixing-feeding system. At least two precise gear metering pumps, a mass flow meter and a dynamic mixer are sequentially arrayed on a liquid trough, an inlet of each precise gear metering pump is connected with a feeding pipe, the feeding pipe is connected with a raw material liquid trough, and outlets of the precise gear metering pumps are connected with an inlet of the mass flow meter through a conveying pipeline so as to form a closed-loop system; and the mass flow meter is connected with the controller, and the controller is connected with a control display through a special cable; and an outlet of the mass flow meter is connected with a liquid inlet in the dynamic mixer through a pipeline, and a liquid outlet in the dynamic mixer is connected with a liquid inlet in a downstream coating machine through a supply pipe.

Description

technical field [0001] The invention relates to a mixing feeding system, in particular to conveying multiple liquids separately and feeding them in the state of online mixing. Background technique [0002] The coating liquid must be prepared before the existing coating. Conventionally, various liquids of different components are mixed together for stirring, and the fully stirred coating liquid enters the downstream from the feeding pipeline for coating. The disadvantage is that due to The preparation of a variety of different materials, if not used up within the effective time, will produce changes in chemical properties, such as the preparation of PCB photosensitive film mixture, the viscosity will increase after a long time, and it will also produce sensitivity and fog. Changes, so this will affect the quality of downstream coating products, generate waste, and increase production costs for enterprises. Contents of the invention [0003] The task of the present inventio...
