Abstract

The utility model relates to an anti-clogging spray device, which mainly comprises a steel pipeline and a filter pipe, wherein one side of the steel pipeline is provided with a nozzle installation hole, holes are uniformly distributed on the filter pipe, the steel pipeline and the filter pipe are of an eccentric structure, and the space which is close to the nozzle installation hole is more than that on the far end; two ends of the spray device adopt the thread connection structure; the holes of the filter pipe are of a conical structure, the diameter of the holes at the inner side is small, the diameter of the holes at the outer side is large, and the diameter of the holes at the inner side of the filter pipe is smaller than that of the nozzle installation hole; a filter screen mesh adopts a conical structure, so that the clogging possibility is greatly reduced, the filter screen is installed at the side which is away from the nozzle installation position and can be installed eccentrically so as to increase the space for water to enter the nozzle; and when part of the meshes of the filter screen are clogged, the filtered water at other position can flow to the part, so that the nozzle at the part can spray water normally.

Description

A kind of anti-blocking spray equipment

Technical field:

The utility model relates to a kind of spray equipment, especially a kind of cooling sprayer that is used on the plastic extruder.

Background technology:

Need to use spray system that tubing is cooled off in the plastic pipe processing industry, the quality of spray effect directly influences the physical and mechanical properties of outward appearance, physical dimension and the tubing of tubing.But because industrial water, stopping state appears in spray system unavoidably, causes the spray effect to descend.At this moment have to clear up spray system, cause to produce and interrupt.Spray system generally is made up of spray piping, filter and shower nozzle three parts in the prior art, impurity in the water is wished to filter in filter and is resolved, in fact in running, because the filter area of filter is limited, the increase of impurity causes the reduction of hydraulic pressure easily, and then influence spray effect.

Summary of the invention

The purpose of this utility model is to avoid the deficiencies in the prior art and proposed a kind of anti-blocking spray equipment.

The technical scheme that the utility model adopted is:

A kind of anti-blocking spray equipment mainly is made up of steel conduit and screen pipe, and a side of steel conduit has the nozzle installing hole, uniform eyelet on the screen pipe, and steel conduit and screen pipe are eccentric structure, near the space greater than far-end, the space of nozzle installing hole; The two ends of spray equipment adopt helicitic texture to connect.

The eyelet of screen pipe is a conical structure, and medial aperture is little, and aperture, the outside is big, and the aperture of screen pipe inboard is less than the aperture of nozzle installing hole.

The beneficial effects of the utility model are: the screen pack eyelet adopts conical structure, can greatly reduce the probability of obstruction, screen pack is installed in the side away from the shower nozzle installation site, adopt eccentric the installation, can increase water and enter the space of shower nozzle, when screen pack part mesh stopped up, the water of other location filterings can flow to this position, guaranteed that this position shower nozzle can normally spray water.

Fig. 2 is the generalized section of spray equipment.

Fig. 3 is the cell structure schematic diagram of screen pipe.

The specific embodiment

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1, 2, a kind of anti-blocking spray equipment, this structure is made up of steel conduit 2 and screen pipe 3, steel conduit 2 and screen pipe 3 disalignments, be eccentric structure, the space of close nozzle installing hole 1 is greater than the space of far-end, and a side of steel conduit 2 has nozzle installing hole 1, uniform eyelet 4 on the screen pipe 3, water passes eyelet 4 from the inboard of screen pipe 3 and enters the cavity of being made up of steel pipe 2 and screen pipe 3, and at this moment water is filtered, free from admixture, enter nozzle through nozzle bore 1 then, spray.

Helicitic texture 5 is adopted at the two ends of this spray equipment, and adopting helicitic texture is for convenience of connecting pipe, can unclamp duct element simultaneously when stopping up appears in screen pipe, cleaning means pipe blow-throughs such as convenient use wire brush.

As shown in Figure 3, the structure of screen pipe filtering holes is a kind of conical structure, and this conical structure is that the screen pipe medial aperture is little, and the aperture of screen pipe inboard is less than the spray orifice aperture of nozzle.Aperture, the screen pipe outside is big.

Claims (2)

1, a kind of anti-blocking spray equipment, mainly form by steel conduit and screen pipe, a side that it is characterized in that steel conduit (2) has nozzle installing hole (1), screen pipe (3) is gone up uniform eyelet (4), steel conduit (2) and screen pipe (3) are eccentric structure, and the space of close nozzle installing hole (1) is greater than the space of far-end; The two ends of spray equipment adopt helicitic texture (5) to connect.

2, a kind of anti-blocking spray equipment according to claim 1 is characterized in that: the eyelet (4) of screen pipe (3) is a conical structure, and medial aperture is little, and aperture, the outside is big, and the aperture of screen pipe (3) inboard is less than the aperture of nozzle installing hole (1).
