Problems solved by technology

[0003] If the existing vacuum suction box loses vacuum during use or the drainage is not timely, the internal vacuum degree of the vacuum suction box is likely to decrease, thereby reducing the dehydration efficiency of the pulp blank, and the drainage is not timely, which is easy to cause The increase in the water volume inside the vacuum suction box reduces the dehydration efficiency, and when the water volume overflows the vacuum inlet, it is easy to cause damage to the vacuum equipment
If the occurrence of these faults cannot be detected in time, it will affect the normal operation of the papermaking equipment, reduce the water absorption rate, cause the paper to fail to form, etc., reduce work efficiency and cause

Abstract

The invention relates to the technical field of fault alarms for papermaking equipment, in particular to a monitoring alarm for a vacuum water suction box of a paper machine and a method for using the same. An alarm platform is fixed on the outer right wall of the tank body, and a failure alarm mechanism is set on the alarm platform. A vacuum trigger mechanism is installed on the upper part of the right wall of the vacuum suction tank body, and the vacuum trigger mechanism is connected to the failure alarm mechanism. The bottom of the vacuum suction tank body is provided with a drainage failure trigger mechanism, and the drainage failure drainage mechanism is connected to the failure alarm mechanism through transmission. The monitoring alarm for the vacuum water suction box of a paper machine and its use method can send a corresponding alarm in time when a fault occurs, reducing the impact of the fault on the entire papermaking equipment, and the alarm mechanism can automatically alarm after the fault is eliminated.

Description

technical field [0001] The invention relates to the technical field of fault alarms for papermaking equipment, in particular to a monitoring alarm for a vacuum suction box of a papermaking machine and a method for using the same. Background technique [0002] The vacuum suction box on the paper machine is used to vacuum and absorb the formed pulp blanks to dehydrate the pulp blanks. [0003] If the existing vacuum suction box loses vacuum or the drainage is not timely during use, the internal vacuum degree of the vacuum suction box is likely to decrease, thereby reducing the dehydration efficiency of the pulp blank, and the drainage is not timely, which is easy to cause The increase in the water volume inside the vacuum suction box reduces the dehydration efficiency, and when the water volume overflows the vacuum inlet, it is easy to cause damage to the vacuum equipment. If the occurrence of these failures cannot be detected in time, it will affect the normal operation of t...
