A pressure control system and control method

Abstract

This paper discloses a pressure control system and a control method. The system is provided with a first air pressure tank, a second air pressure tank, a delivery pipeline and a control circuit; the method includes the following steps: step a, in the initial state, the first air pressure tank Both the second air pressure tank and the second air pressure tank are set to a full tank state; the control circuit controls the first electromagnetic valve at the bottom end of the first air pressure tank to be in a fully open state, and controls the second electromagnetic valve at the bottom end of the second air pressure tank to be in a fully closed state, etc.; this application can be applied to auxiliary equipment for the production of mineral wool boards, and the application of this application can effectively solve the defects existing in the prior art, and can realize the technical effect of replacing the tank body without stopping the machine, and can effectively improve the production efficiency of the equipment; in addition, It can provide stable pressure air, and can effectively avoid process instability caused by compressed air fluctuations.

Description

technical field [0001] This application relates to but not limited to auxiliary equipment for mineral wool board production, especially a pressure control system and control method. Background technique [0002] In the prior art, mineral wool boards have superior performances such as sound absorption, non-combustibility, heat insulation, and decoration, and are widely used in various building ceilings and interior decorations attached to walls. The commonly used production process of mineral wool board mainly includes the following steps: loosening of mineral wool, paper grinding and beating, mixing and stirring, entering the constant position tank, putting pulp on the net, forming, entering the room for drying, cutting and beating the board out of the board, drying, Spraying, embossing, cutting, spraying adhesive, packaging and storage, etc. Among them, it is often necessary to provide compressed air through an air tank during production. [0003] However, the air tank pr...

AI Technical Summary

Problems solved by technology

[0003] However, the air tank pressure supply system used as a sheet metal production line has the following defects: first, the compressed air tank needs to be shut down for corresponding replacement operations after use, which seriously reduces production efficiency; second, the pressure tank is constantly under pressure during use. Decline, there is a certain fluctuation in the compressed air provided, which affects the subsequent related processes of the production line
