The specific maintenance method of the filter is as follows:
1. The filter cleans the groove and leaks the new surface.Clean it with a small saw blade.
2. filter filter plate black and white two repair agent ratio of 1:1.
3. Apply the prepared patch to the groove, and then add a little more.
4. The press filter plate quickly sets the filter cloth to squeeze the filter plate together to stick the restorative and filter cloth together while squeezing the grooves.
5. After filter filter extrusion for a period of time, the adhesive forms naturally and no longer changes.At this point, it can use it normally.
According to the above method, the filter plate can be better applied, and the cost can be saved.
In terms of filter form, the filter has compartment and frame type.Filplates were placed in different directions and had vertical and horizontal separation.Filfilters have different materials, including plastic, rubber, cast iron, cast steel, carbon steel, stainless steel.Whether the filter plate contains rubber extrusion film, extruded dehydration and non extrextrusion dehydration.The filter plate configuration has different filter cloth surfaces, single-sided dehydration and double-sided dehydration points, etc.However, no matter which press, its working principle is to first conduct positive pressure dehydration, also known as slurry dehydration, that is, a certain number of filter plate in a tight row under the action of strong mechanical force, the surface and filter plate surface.A filter chamber is formed between the filter materials and delivered to the filter chamber under strong positive pressure.The solid portion of the filter material entering the filter chamber is captured by the filter medium (e. g., the filter cloth) to form a filter cake, and the liquid portion is discharged through the filter medium.The filtration chamber was used for solid-liquid separation.Solid-liquid separation is more thorough as positive pressure increases, but excessive positive pressure is not cost-effective in terms of energy and cost.After the slurry is dehydrated, using a press equipped with a rubber extrusion film, the compression medium (such as gas or water) enters the back of the extrusion film, pushing the extrusion film to further dehydration the extrusion filter cake, which is known as extrusion dehydration.After the slurry is dehydrated or squeezed, the compressed air enters the filter cake side through the filter cake, and the liquid water is discharged from the other side of the filter cake through the filter cloth to discharge the filter.The room should be dehydrated.If the filter cloth is applied to both sides of the filter chamber, the liquid portion may pass through the filter cloth on both sides of the filter chamber and leave the filter chamber to dehydrate the filter chamber.After dehydration, release the mechanical pressure of the filter plate, and gradually open the filter plate sheet, and open the filter chamber separately to complete the unloading of the filter cake.Depending on the properties of the filter material, the press can be set to slurry dehydration, extrusion dehydration, wind blowing or single and two-sided dehydration, to greatly reduce the moisture of the filter cake.
