Problems solved by technology

[0002] As we all know, the current full-automatic bottom unloading centrifuge generally has excessive vibration during the feeding process. There are many reasons for the excessive vibration. If it is caused by the uneven distribution of materials in the drum, the drum will vibrate for a long time. If the operation exceeds the standard, it will accelerate the aging of the drum and greatly shorten its service life; if it is caused by the mechanical failure of the centrifuge, if the centrifuge is not found and shut down in time, it will cause a major accident and seriously threaten the life of the centrifuge. Personal safety of people around the centrifuge

Embodiment Construction

[0011] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 , figure 2 As shown, the control device of the fully automatic unloading centrifuge of the present invention includes: a controller, a vibration intensity meter 4 and a vibration sensor arranged on the centrifuge casing 1, and the output end of the vibration sensor It is connected to the input end of the vibration intensity meter 4, and the output end of the vibration intensity meter 4 is connected to the input end of the controller. In this embodiment, the vibration sensor is a magnetoelectric vibration sensor 3, and the controller is a programmable logic controller 5, namely PLC.

[0013] When vibration occurs during the operation of the centrifuge, the coil inside the magnetic vibration sensor cuts the magnetic force line and outputs different equivalent voltage signals

[0014] After the present invention instal...

Abstract

The invention discloses a control device for a full automatic discharge centrifuge with safety protection device, comprising a controller, a vibration intensity scale and a vibration inductor arranged on the casing of the centrifuge; wherein, the output end of the vibration inductor is connected with the input end of the vibration intensity scale; the output end of the vibration intensity scale is connected with the input end of the controller. As a vibration inductor and a vibration intensity scale are added to the control device, the vibration intensity scale can compare the voltage value from the vibration inductor with the preset alarm threshold voltage value; if the overproof vibration continues after a certain time, the rotating drum is shut down and the centrifuge is overhauled; thus accidents are avoided and the personal safety of the operators around the centrifuge is reliably protected.

Description

technical field [0001] The invention relates to a control device, in particular to a control device for a full-automatic down-discharging centrifuge. Background technique [0002] As we all know, the current full-automatic bottom unloading centrifuge generally has excessive vibration during the feeding process. There are many reasons for the excessive vibration. If it is caused by the uneven distribution of materials in the drum, the drum will vibrate for a long time. If the operation exceeds the standard, it will accelerate the aging of the drum and greatly shorten its service life; if it is caused by the mechanical failure of the centrifuge, if the centrifuge is not found and shut down in time, it will cause a major accident and seriously threaten the life of the centrifuge. Personal safety of personnel around the centrifuge. Contents of the invention [0003] A technical problem to be solved by the present invention is to provide a control device for a fully automatic ...
