Problems solved by technology
[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 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 be unable to form, etc., reduce the work efficiency and cause

The invention relates to the technical field of papermaking equipment fault alarm, specifically to a monitoring alarm for a vacuum water suction box of a papermaking machine and a using method for themonitoring alarm. The monitoring alarm comprises a vacuum water suction box body, wherein a water pump and a vacuum pump are arranged at the bottom part of the vacuum water suction box body; an alarmtable is fixedly arranged on the right side wall of the exterior of the vacuum water suction box body; a fault alarm mechanism is arranged on the alarm table; a vacuum loss trigger mechanism is arranged at the upper part of the right side wall of the vacuum water suction box body and is in transmission connection with the fault alarm mechanism; and a drainage fault trigger mechanism is arranged at the bottom part of the vacuum water suction box body and is in transmission connection with the fault alarm mechanism. According to the monitoring alarm for the vacuum water suction box of the papermaking machine and the using method of the monitoring alarm, when a fault occurs, a corresponding alarm is given in time, so the influence of the fault on the whole papermaking equipment is reduced; meanwhile, after the fault is removed, the alarm mechanism can automatically give an alarm.
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 to vacuumize 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 of water in the vacuum suction box reduces the dehydration efficiency, and when the water 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 the papermaking equipment...
