Abstract

The utility model relates to a multifunctional filter. The utility model is provided with a housing [1], a cover plate [4], a screw [6] and a filtering net layer [7], besides, a feeding cavity is provided with a feeding port [9] and a heating pipe [8], both ends [2] and [10] of the heating pipe [8] penetrate through the housing [1] to the outside, and a discharging cavity is provided with a discharging port [3] and a magnetic rod [5] which is fixed between the filtering net layer [7] and the cover plate [4] of the housing [1]. The utility model is reasonable in design and has favorable filtering effect; the utility model has the functions of magnetic absorption and thermal dissolution and can prevent clogging and remove metal foreign matters, which guarantees the continuity and safety of subsequent manufacture and production and raises the production efficiency and product quality; besides, the utility model has the advantages of simple structure, wide application range and strong practicability.

Description

Multi-functional filter

Technical field

The utility model relates to a kind of equipment for separating liquid from solid, and particularly a kind of have that magnetic is attached, the anti-clogging multi-functional filter of thermosol function.

Background technology

In the prior art, equipment for separating liquid from solid is used very extensive in industrial production, and its effect is that solid matter and liquid substance are separated, and generally adopts filter to realize.In the petrochemical industry OIL IN LUBRICATING OIL PRODUCTION, as heavy grease benzol-kentone dewaxing process units, because operating temperature is lower, big wax stone is not easy to dissolve fully, influence the normal operation of downstream unit, before the pump inlet of downstream unit wax filter is set, purpose is to filter big wax stone, filters some other solid impurity again for this reason, but because employed filter, in long-time running, wax liquid solidifies caking on filter screen, block filter screen easily, can't in time judge the degree of congestion of filter screen, cause cutout, burn pump or the erroneous judgement filter screen blocks, and knownly only change the material of filter screen and the aperture of filter opening is unpractical, also can't eradicate above-mentioned problem; And often be mixed with some tiny metallic particles in the wax liquid; there is not a kind of effective way that it is removed; cause these tiny metallic particles to be brought in wax pump one screw pump in downstream through filter; cause the wearing and tearing of screw pump and even burn out; thereby cause damage; what influence was produced normally carries out, and has increased production cost.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved multi-functional filter is provided, and effectively removal of contamination prevents that filter screen from stopping up, and guarantees production continuity and security, enhances productivity and economic benefit.

The purpose of this utility model can realize by following technical measures: in the housing of this filter filter mesh layer is housed, filter mesh layer is separated into feed cavity and discharging chamber with the housing inner chamber, feed cavity is provided with charging aperture, the discharging chamber is provided with discharging opening, is provided with heating tube in feed cavity, and heating tube is near filter mesh layer, the cross-under of heating tube two ends is outside housing, in the discharging chamber, be provided with bar magnet, in the bar magnet distribution discharging chamber, be fixed between filter mesh layer and the housing cover.In the practical application, pressure sensor is housed on the filter, heating tube connects steam, and during work, filter screen is solidified the clogged up with material of caking, pressure sensor detects pressure change signal, the steam of heating tube is connected in control, and heating is dissolved and solidified caking, the mediation filter screen, it is attached that bar magnet carries out magnetic again to filter material, reaches further purification effects.

The utility model is reasonable in design, good filter effect is arranged, have magnetic simultaneously and echo the thermosol function, can prevent to stop up, remove metal impurities, guarantee continuity and security that following process is produced, improve production efficiency and product quality, it is simple in structure, adapts to widely, not only can be used for heavy, light lubricating oil process units, also can be used in other equipment for separating liquid from solid, practical.

Description of drawings

Fig. 1 is a structure chart of the present utility model.

The specific embodiment

With reference to Fig. 1, this filter has housing [1], filter mesh layer [7] is arranged in the housing [1], filter screen [7] links into an integrated entity by screw [6] and upper cover plate [4], can extract out and put into upper cover plate [4], filter mesh layer [7] is separated into upper and lower two inner chambers with housing [1] inner chamber, lower inner cavity is a feed cavity, charging aperture [9] is arranged, and last inner chamber is the discharging chamber, and discharging opening [3] is arranged, heating tube [8] is housed in the feed cavity, heating tube [8] is near filter mesh layer [7], and heating tube [8] two ends [10], [2] cross-under are connected with steam pipe outside housing [1].Be distributed with bar magnet [5] in the discharging chamber, bar magnet [5] is fixed between the upper cover plate [4] of filter screen [7] and housing.

During use, material is entered in the housing [1] by charging aperture [9], after filtering, filter mesh layer [7] comes out by discharging opening [3], tiny metallic particles can regularly be extracted magnet [5] out by upper cover plate [4] and remove to remove adsorbate then by bar magnet [5] absorption, has guaranteed the filtrate filtered quality, when filter mesh layer [7] upward solidifies the caking obstruction because of material, feed steam at heating tube [8], heating is dissolved to caking, guarantees that filter screen [7] is unobstructed.Can on housing, install pressure sensor, realize control heating automatically, report to the police automatically, be convenient for people to the condition of production is monitored.

Claims

1, a kind of multi-functional filter, housing [1], cover plate [4], screw [6], filter mesh layer [7] are arranged, filter mesh layer [7] is separated into feed cavity, discharging chamber with the housing inner chamber, and feed cavity has charging aperture [9], and there is discharging opening [3] in the discharging chamber, it is characterized in that in feed cavity, being provided with heating tube [8], heating tube [8] is near filter mesh layer, and the cross-under of heating tube two ends is provided with bar magnet [5] in the discharging chamber outside housing, in bar magnet [5] the distribution discharging chamber, be fixed between filter mesh layer [7] and the housing cover [4].
