Abstract

The utility model relates to a flushing type multiple stage heavy oil filter which solves the problems that a filtration effect is poor, and time and labor are wasted. The utility model is characterized in that the upper end and the lower end of the corresponding side of a casing (13) are respectively connected with an oil inlet and an oil outlet (15, 14); a plurality of filtering nets (1, 4) which are arranged at intervals and are parallel to a pressing cover (11) are arranged between the upper end of the oil inlet (14) and the oil outlet (15) through a support frame (12); the upper end of the support frame (12) is fixed with a hole type disc (5); a spring (10) fixed between the hole type disc (5) and the pressing cover (11) is corresponding to a steam joint (6) on the pressing cover (11); the bottom end of the casing (13) forms a conical collecting body (9) and a sewage draining exit (7); the lower end of the oil inlet (14) is fixed with a guide plate (8) in the casing (13). The utility model has the characteristic of good filtration effect. Simultaneously, the filtering nets can be automatically flushed, which reduces labor intensity.

Description

The multistage heavy oil filter of flushing type

Technical field

The utility model relates to a kind of fuel oil filter of oil burning boiler, particularly relates to the multistage heavy oil filter of a kind of flushing type.

Background technology

The oil burning boiler that warming is used, for saving cost, the employing heavy oil that has acts as a fuel, because the heavy oil impurities is many, needs to filter, the heavy oil filter application of using is dull and stereotyped rectangle net or cylindrical net at present, heavy oil directly is filled into the oil-out corresponding with it, PARALLEL FLOW from oil-in, and poor filtration effect often quits work because of stopping up burner, and the gland that need open on the housing when inspection or flushing impurity screening is handled, and wastes time and energy.

The utility model content

For the deficiency that overcomes present technical filter weak effect, wastes time and energy, the utility model provides a kind of flushing type multistage heavy oil filter, this device good filtration effect, high efficiency.

The invention for solving the technical problem can reach by following technical solution: the upper and lower end in the housing respective side is connected with out respectively, oil-in, between the upper end of oil-in and oil-out, some screen packs parallel with gland at interval fixedly are housed by support, be fixed with the cellular type dish in the upper end of support, fixing spring is corresponding with steam joint on the gland between cellular type dish and the gland; The housing bottom forms a cone-shaped collection body and a sewage draining exit; In the oil-in lower end in housing fixing deflector.

In such scheme, screen pack is 2, and being positioned at the mesh diameter of screen pack at oil-in place and the mesh diameter difference of another screen pack is positive number.

The utility model is compared with background technology has following beneficial effect: since the utility model adopts the multistage filtering net and into and out of hydraulic fluid port not on same horizontal line, changed the mode of the advection of oil in filter for flowing vertically upward, the big impurity such as sand of part weight can directly avale good filtration effect; The gland top connects steam joint, during flushing, inserts steam pipe, but automatically washing filter screen flows to the heavy oil in the housing owing to contact with the orlop screen pack by oil-in simultaneously, also can reach the effect of automatically washing filter screen, has alleviated labour intensity.

Description of drawings

Accompanying drawing is the utility model structure cut-away view.

Among the figure: 1-screen pack, 2-pressure ring, 3-support ring, 4-screen pack, 5-cellular type dish, 6-steam joint, 7-sewage draining exit, 8-deflector, 9-collection body, 10-spring, 11-gland, 12-support, 13-housing, 14-oil-in, 15-oil-out.

The specific embodiment

Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:

By shown in Figure 1, upper and lower end in housing 13 respective side is connected with respectively into and out of hydraulic fluid port (15,14), between the upper end of oil-in 14 and oil-out 15, the parallel screen pack (1 of at interval 2 and gland 11 fixedly is housed by support 12,4), the difference of the mesh diameter of the mesh diameter of screen pack 1 and screen pack 4 is a positive number.Be fixed with cellular type dish 5 in the upper end of support 12, fixing spring 10 is corresponding with steam joint 6 on the gland 11 between cellular type dish 5 and the

gland

11,5 pairs of vapor streams of cellular type dish disperse decompression, prevent the excessive damage screen pack of pressure, bottom at housing 13 forms cone-shaped collection body 9 and sewage draining exit 7, in oil-in 14 lower ends in housing 13 fixing deflector 8, prevent that the heavy oil disturbance has been deposited in the impurity in the collection body 9.

During actual the use, heavy oil is after oil-in 14 enters, because pressure effect, upwards flow, filter the back through filter screen (1,4) and flow out by oil-out 15, flow to the heavy oil in the housing 13 owing to contact by oil-in 14 with screen pack 1, but automatically washing filter screen 1, pressure ring 2 tightly contacts with support ring 3, prevents that heavy oil from oozing out outside filter screen; When flushing, close into and out of hydraulic fluid port (14,15) valve, the steam joint 6 access steam pipes of gland 11 upper ends, vapor stream evenly is sprayed on the screen pack (1,4) and washes after cellular type dish 5 disperses decompression, collect when a certain amount of when impurity, open sewage draining exit 7, discharge impurity.

Claims

1, the multistage heavy oil filter of a kind of flushing type, comprise and having into, oil-out (14,15) and the housing (13) of gland (11), it is characterized in that: on housing (13) respective side, the lower end is connected with out respectively, oil-in (15,14), between the upper end of oil-in (14) and oil-out (15), some parallel with gland (11) screen pack (1 at interval fixedly is housed by support (12), 4), be fixed with cellular type dish (5) in the upper end of support (12), fixing spring (10) is corresponding with steam joint (6) on the gland (11) between cellular type dish (5) and the gland (11); Housing (13) bottom forms a cone-shaped collection body (9) and sewage draining exit (7); In oil-in (14) lower end in housing (13) fixing deflector (8).
