Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] As shown in Figure 1. The static logic controller for the blanking of the alumina blanking scale of the present invention is composed of five parts: an anti-interference circuit 1, an instruction latch circuit 2, a static logic control circuit 3, a drive circuit 4, and DC-light-AC. The anti-interference circuit 1 consists of an impedance coil 7 and a capacitor 8, as shown in Figure 2; the command latch circuit 2 consists of a gate circuit 9 that can write control discharge, feeding, and stop signals, a high-level button switch 10 and a low-voltage Flat button switch 11 is formed, as shown in Figure 3; Described static logic control circuit 3 is by control R chute blanking, F chute blanking and discharging three working states of R chute blanking, F chute blanking, supply A logic control circuit 12 composed of 6 signals of material master gate, d...

Abstract

The invention relates to a controlling system, especially to a baiting controller of aluminum oxide baiting scale in aluminium electrolysis industry. The invention comprises an anti-interference circuit, a direction latching circuit, a static logical control circuit, a driving circuit and a DC-light-AC. The invention has the beneficial effects as: it integrates the five parts of non-contactor controller into one circuit board, decreases wiring, reduces volume and replaces the relay control circuit completely; it applies simple logic gate circuit control, improves level of resources utilization; it applies electromagnetic field proof high-low electrical level in the whole control, obtains stable performance; and it can eliminate the defections of death and malfunction in the run procedure. The invention can be used in baiting control system of aluminum oxide baiting scale in aluminum electrolysis industries, also can be used in baiting control system for material in food processing and material storage, and in blower fan engine control for simple vehicle and industrial boiler.

Description

technical field [0001] The invention relates to a logic control system, which is characterized in that it relates to a static logic controller for the feeding of alumina feeding scales in the aluminum electrolysis industry. Background technique [0002] At present, in the aluminum electrolysis industry, the feeding control system of alumina feeding scales uses buttons and function switches to issue instructions, and the control part of the relay executes the instructions to control the solenoid valve to realize the supply of electrolytic aluminum production. The control system has a total of 200 terminals, 23 relays, 6 buttons and 3 function switches. The contacts of each component are often switched on and off to generate electric sparks, so that the scratches on the contact surface cause poor contact and cause equipment failure. rate increased significantly. Improving the existing controller as a non-contact control system is an effective solution to reduce the failure ra...
