Control method used for spinning cake dewaterer

Abstract

The invention discloses a control method for a silk cake dehydrator, which includes a step of starting a disk and a step of starting a dehydration barrel, and further includes: a step of detecting a starting point and a step of detecting the position of the dehydration barrel before the step of starting the dehydration barrel, so that The start point detection step is to use the proximity switch I to detect the position of the start point on the index plate, and the dehydration bucket position detection step is to use the proximity switch II to detect the position corresponding to the dehydration bucket on the index plate after the start point is detected by the proximity switch I. The position of the detection point; the starting step of the dehydration bucket is that after the detection point is detected by the proximity switch II, the controller starts the rotation of the dehydration bucket corresponding to the detection point position for dehydration. The invention does not cause error accumulation, thereby further ensuring that the stop area of ​​the dehydration bucket does not change; the circuit is simple, the maintenance is convenient, and the failure rate is low.

Description

technical field

[0001] The invention relates to the field of dehydrator control, in particular to a control method for a silk cake dehydrator. Background technique

[0002] The current dehydration method of the disc dehydrator is composed of a disc and a centrifugal dehydration barrel. The main rotating motor of the disc dehydrator drives the disc to make a circular motion. There are multiple centrifugal dehydration barrels on the disc. The barrel uses a dehydration motor to drive the dehydration barrel to rotate at high speed to dehydrate the silk cake. The starting and energy consumption braking of each dehydration motor are controlled by a travel switch, so that the dehydration machine system has many travel switches and the control system is complicated. This contact travel switch has poor reliability after repeated collisions, short service life, and needs frequent maintenance and replacement; the control circuit is controlled by relays and contactors, which makes the ...
