Abstract
The utility model relates to an on-line filtering device of a coal conveying pipeline. The on-line filtering device can be used for intercepting sundries carried by coal slurry in a filtering pipeline on line so as to completely eliminate potential safety hazards and economic losses caused by the sundries. The on-line filtering device consists of a normal Y-shaped pipeline, a reverse Y-shaped pipeline, pressure meters, a filtering unit I, a filtering unit II, valves and flanges, wherein the filtering unit I and the filtering unit II have the same structure and are respectively formed by connecting a filtering pipe, two layers of filtering nets, two valves and three groups of flanges in a certain sequence. The non-branch pipelines of the normal Y-shaped pipeline and the reverse Y-shaped pipeline are respectively provided with one pressure meter; and the sudden increase of the pressure difference change of the two pressure meters shows the existence of the sundries in the filtering pipes. The two filtering units are standby for each other, and the normal continuous operation of the coal conveying pipeline is ensured when the sundries in the filtering pipes are cleared away.
Description
Technical field
The utility model relates to a kind of convey coal pipe on-line filtration device, belongs to long apart from convey coal pipe engineering pipeline filter plant technical field.
Background technology
Long apart from the convey coal pipe engineering, owing in processes such as pipeline welding, workman's operation and overhaul of the equipments, because of carelessness foreign material such as metalloid bar, cloth are remained in the pipeline easily.Stock pump and the main delivery pump of feeding along the line is apt to cause breakage or block when suffering such foreign material, and the lighter's damage equipment, severe patient can cause that whole tubing paralyses temporarily, bring serious potential safety hazard and economic loss.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of convey coal pipe on-line filtration device, and the foreign material of carrying secretly in can online interception filter pipe coal slurry are thoroughly eliminated potential safety hazard and the economic loss of bringing because of foreign material.
For achieving the above object, the utility model is by the following technical solutions:
Convey coal pipe on-line filtration device mainly is made up of positive Y-piece road, anti-Y-piece road, Pressure gauge, a filter element, No. two filter elements, valve, flanges, a wherein said filter element is identical with described No. two filter element structures, connects to form in certain sequence by screen pipe, screen pack, two valves, three-group method orchids.The furcated end in positive Y-piece road and anti-Y-piece road is docked in opposite directions, is separately installed with a filter element and No. two filter elements by the flange mode between the two.
Further, on the not bifurcated segment pipe in positive Y-piece road and anti-Y-piece road a Pressure gauge is housed respectively, when two manometric pressure reduction changed increase suddenly, showing to have had foreign material in the screen pipe.
Further, screen pipe is funnel shaped, and the diameter of screen pipe is the twice of convey coal pipe diameter.
Further, establish two-layer screen pack in the screen pipe.
Further, the mesh diameter of screen pack is three times of coal particle maximum particle diameter in the defeated coal slurry of pipe.
Further, the screen pipe between two-layer screen pack is equipped with a flange, flange is opened can be removed the foreign material that are trapped in the screen pipe.
Further, when convey coal pipe normally moved, one of them of opening in filter element and No. two filter elements carried out work, and another is as standby, when the filter element of this work unloads the removing foreign material, enable standby filter element, guarantee the normal operation continuously of convey coal pipe thus.
The beneficial effect of this convey coal pipe on-line filtration device: the foreign material of carrying secretly in can online interception filter pipe coal slurry, thoroughly eliminate potential safety hazard and the economic loss of bringing because of foreign material, and guarantee the normal operation continuously of convey coal pipe during the foreign material in removing screen pipe.
