Abstract
The utility model discloses an automatic metering system for cement grinding aids. The automatic metering system comprises a grinding aid metering pump, a grinding aid storage tank, a flow meter, a cement mill, a DCS (Distributed Control System) control cabinet and an upper computer, wherein an outlet of the grinding aid storage tank is provided with the grinding aid metering pump; the outlet of the grinding aid storage tank is connected with an inlet of the grinding aid metering pump by a pipeline; an outlet of the grinding aid metering pump is connected with an inlet of a cement mill by a pipeline; and the flow meter is arranged on the pipeline connecting the outlet of the metering pump with the inlet of the cement mill. The automatic metering system for the cement grinding aids has the advantages that the stability of the cement product quality is further ensured by performing effectively on-line monitoring and timely adjusting on the adding amount of the grinding aids, so that conditions are created for the development of enterprises and the rapid development of the cement industry.
Description
Technical field
The utility model relates to a kind of automatic metering system, particularly relates to a kind of cement grinding aid automatic metering system.
Background technology
Along with the development of society, grinding aid is widely applied in manufacture of cement, but rationally controls accurately the addition content of grinding aid, and also there is certain deficiency in each enterprise at present.Through the discovery of visiting to many cement production enterprises, aspect grinding aid addition content and monitoring, have following problem: owing to can't obtain on-line monitoring to the grinding aid addition content in the cement production process, cause the grinding aid addition content what be difficult in time to adjust according to the variation of output; Can not accurate and effective control the grinding aid addition content, will have a strong impact on product quality.
The utility model content
The purpose of this utility model is to provide a kind of cement grinding aid automatic metering system.
The purpose of this utility model is implemented by following technical scheme, a kind of cement grinding aid automatic metering system, it comprises the grinding aid volume pump, the grinding aid hold-up vessel, flowmeter, cement mill, DCS system control cabinet and host computer, the exit of described grinding aid hold-up vessel is provided with described grinding aid volume pump, the outlet of described grinding aid hold-up vessel is connected by pipeline with the entrance of described grinding aid volume pump, described grinding aid metering delivery side of pump is connected by pipeline with the entrance of described cement mill, the pipeline that connects the entrance of described grinding aid metering delivery side of pump and described cement mill is provided with described flowmeter, the signal output part of described flowmeter is connected with the signal input part of described DCS system control cabinet, the signal output part of described DCS system control cabinet is connected with the signal input part of described grinding aid volume pump, and described DCS system control cabinet is connected with described host computer.
Distance between described flowmeter and the outlet of described grinding aid volume pump is 10 meters.
Do grinding aid volume pump automatic control program one cover, flowmeter on-line monitoring program one cover by DCS procedure operation, operation host computer, be downloaded to the DCS system control cabinet, program brings into operation.When flowmeter moves to direct current 4-20mA analog quantity current signal of DCS system control cabinet feedback, through program is inner convert after at the actual addition content of the current grinding aid of ipc monitor picture disply; When the grinding aid volume pump brings into operation, variation according to output provides order by host computer at any time according to the admixture index, provide a direct current 4-20mA analog quantity current signal to the grinding aid volume pump after converting voluntarily by the DCS system control cabinet, the grinding aid volume pump is received the rotating speed that comes regulating electric machine behind the signal according to the size of analog quantity electric current, controls what of grinding aid addition content with this.
The utility model has the advantage of, by the grinding aid addition content is carried out effective on-line monitoring and adjust in good time, further guarantee the stability of cement product quality, create conditions for the development of enterprise and the develop rapidly of cement industry.
