PLC automatic batching control system for refractory material

Abstract

The invention relates to a PLC automatic batching control system for refractory materials. The PLC automatic batching control system is composed of a WinCC system, a PLC control system, a weighing system and a vibration feeding system. The WinCC system realizes real-time monitoring of the whole batching process. The PLC controls a parallel blanking mode, so that the production efficiency is improved. The weighing system is provided with secondary weighing, so that the weighing is more accurate. The vibration feeding system is provided with different vibration feeders according to different powder materials and particle materials, equipment faults are reduced, and the maintenance difficulty is reduced.

Description

Technical field [0001] The invention belongs to the field of refractory material production and processing, and specifically is a refractory material PLC automatic batching control system. Background technique [0002] The batching process of the refractory plant is basically divided into three categories: the first type uses manual batching, which has low batching automation, high labor intensity and poor working environment; the second type uses the traditional relay contactor control system with a certain degree of automation Improve, but can only complete the batching control of the fixed formula, and cannot change the batching process according to the change of the formula. The control method is not flexible enough; the third type uses the PLC control system to complete the refractory material formula control and management, and the batching process can be changed according to different formulas , And then weigh different raw materials and add them to the bin one by one to m...

[0002] The batching process of the refractory plant is basically divided into three categories: the first category uses manual batching, which has a low degree of automation, high labor intensity, and poor working environment; the second category uses traditional relay contactor control systems, and the degree of automation is somewhat Improvement, but can only complete the batching control of the fixed formula, and cannot change the batching process according to the change of the formula, and the control method is not flexible enough; the third category uses the PLC control system to complete the formula control and management of refractory materials, and can change the batching process according to different formulas , and then weigh different raw materials and add them to the silo one by one for mixing, realizing automatic batching

[0003] At present, the first type of artificial ingredients has long been eliminated, and the second type of relay contactor control system is gradually eliminated due to the fixed formula that cannot meet the trend of product diversification and complex formula.

The third type of PLC control system has become the mainstream batching process in refractory plants, but the degree of automation is not high, and the batching is done in a serial manner (each raw material is sent to the transport truck or belt conveyor in turn), and the production efficiency is not high.

At the same time, there are both powder and pellets in the raw materials of the refractory plant, and the current batching process basically adopts electromagnetic vibration feeding uniformly, without distinction

In addition, in some processes, both the load cell and the vibrating feeder are placed under the silo, and the material is weighed while vibrating, so that the vibration will cause great interference to the weighing, making the measurement inaccurate.
