Control method and device of filter press material supplementing system, control cabinet and storage medium

Abstract

The invention provides a control method and device of a filter press material supplementing system, a control cabinet and a storage medium, and relates to the technical field of filter press materialsupplementing systems. The method is applied to a controller in a material supplementing system of a filter press. The system comprises a feeding barrel, a plurality of concentrators and the controller, wherein the feeding barrel and the concentrators are electrically connected with the controller; the method comprises the following steps: acquiring liquid level data of the feeding barrel througha liquid level sensor of the feeding barrel; according to preset liquid level parameters and the liquid level data of the feeding barrel, judging whether the feeding barrel meets material supplementing conditions or not, wherein the material supplementing conditions comprise the material supplementing starting condition and the material supplementing ending condition; and if the feeding barrel meets the material supplementing condition, controlling a feeding valve and / or a target thickener underflow pump to be opened or closed, wherein the target thickener is at least one of the thickeners. Byapplying the embodiment of the invention, not only is the labor cost saved, but also the control precision of the material supplementing link of the feeding barrel is improved.

Description

technical field [0001] The present application relates to the technical field of filter press feeding system, in particular, to a control method, device, control cabinet and storage medium of a filter press feeding system. Background technique [0002] The filter press system is generally composed of thickeners, feeding tanks, and filter presses. It is suitable for the solid-liquid separation of various suspended solids, especially in the coal slurry water treatment process of coal preparation plants. The filter press system is indispensable link. [0003] At present, many links in the production process of the filter press system rely on manual operations, especially in the filling process of the feeding tank. The staff need to observe the liquid level of the feeding tank to judge the timing of starting and ending feeding. The staff also need to observe the operating parameters of the concentrator to determine which concentrator underflow pump is started for feeding, and m...

Problems solved by technology

[0004] However, whether it is judging the timing of starting and ending the feeding of the feeding tank, or determining which concentrator underflow pump is needed for feeding, or turning on the concentrator underflow pump and related valves, all rely on manual operation, which not only requires A lot of labor costs, and it will also lead to inaccurate control of the filling link of the feeding tank
