Description

A kind of spinneret for the processing of PP filter core

Technical field

The present invention is specifically related to a kind of spinneret for the processing of PP filter core, belongs to the filter core processing component.

Background technology

at present, it is raw material that PP filter core (claiming again melt-blown filter) adopts nonpoisonous and tasteless polypropylene, through heating and melting, spray, traction, the filter material that receives moulding and make, can effectively remove the suspended matter in liquid, particulate, the impurity such as iron rust, after entering when fluid the PP filter core that is equipped with the certain specification filter screen, its impurity is blocked, and the stream logistics of cleaning goes out, reclaiming industry at waste water is widely used, in PP filter core process, need spinneret to spray the PP fuse, the PP filter core receives the PP fuse in fast rotational, spinneret adopts wind flow to drive the injection of PP fuse, the spinneret orifice place of existing spinneret designs for flat mouth, the speed that causes the PP fuse to spray is not high, crin easily appears, fault appears in the PP cartridge surface, jeting effect is not high, the speed that needs hair-dryer to strengthen wind flow improves the speed that causes the injection of PP fuse, waste energy.

Summary of the invention

In order to overcome the problem of the spinneret existence that is used for the processing of PP filter core in prior art.Spinneret for PP filter core processing provided by the invention is designed to the cone-shaped of sharp mouth with the spinneret orifice place, and wind flow makes and has guiding, can not disperse, accelerate the speed that the PP fuse sprays, jeting effect is high, improve the ratio of briquetting of PP filter core, save the energy, have a good application prospect.

In order to achieve the above object, the technical solution adopted in the present invention is:

A kind of spinneret for the processing of PP filter core, it is characterized in that: comprise the spinneret substrate, the spinneret body has raised up in the middle part of described spinneret substrate, described spinneret body is the triangle cone, and one-body molded with the spinneret substrate, on described spinneret body, the tip is provided with the spinneret orifice that a row is spacedly distributed, and a side of described spinneret substrate is provided with fresh air inlet, the both sides of described spinneret body are provided with wind guide tank, and described wind guide tank is connected with fresh air inlet.

Aforesaid a kind of spinneret for the processing of PP filter core, it is characterized in that: the back of described spinneret substrate is provided with PP fuse feed well, and described PP fuse feed well is connected with the spinneret body.

Aforesaid a kind of spinneret for the processing of PP filter core, it is characterized in that: described PP fuse feed well has been nested with filter, and the outer surface of described filter is provided with one deck stainless steel screen pack.

The invention has the beneficial effects as follows: the spinneret for the processing of PP filter core provided by the invention, the spinneret orifice place is designed to the cone-shaped of sharp mouth, and wind flow makes and has guide function, and wind can not dispersed to both sides and hold, need not to increase the speed of wind flow, the energy-conservation energy just can be accelerated the speed that the PP fuse sprays, and jeting effect is high, improve the ratio of briquetting of PP filter core, and be provided with filter on PP fuse feed well, and can effectively remove impurity, improve the quality of PP filter core.

The specific embodiment

Below in conjunction with Figure of description, the present invention is further illustrated.

as Fig. 1, Fig. 2 and shown in Figure 3, a kind of spinneret for the processing of PP filter core, comprisespinneret substrate 1, thespinneret substrate 1 middle partspinneret body 2 that raised up,spinneret body 2 is the triangle cone, and one-body molded withspinneret substrate 1,spinneret substrate 1 andspinneret body 2 adopt mould steel to make, sound construction, high temperature resistant, high pressure, be convenient to long-term use, onspinneret body 2, the tip is provided with thespinneret orifice 3 that a row is spacedly distributed, one side ofspinneret substrate 1 is provided with fresh air inlet 4, the both sides ofspinneret body 2 are provided withwind guide tank 5,wind guide tank 5 is connected with fresh air inlet 4, during use, on thewind guide tank 5 of both sides, cover plate is installed, fix cover plate by thefixing hole 8 that is arranged onspinneret substrate 1, wind can be along the side flow ofspinneret body 2 like this, the shape of triangle cone can be accelerated the speed of wind flow, and wind can not dispersed to both sides and hold, need not to increase the speed of wind flow, the energy-conservation energy, just can accelerate the speed that the PP fuse sprays, jeting effect is high, improve the ratio of briquetting of PP filter core, the back ofspinneret substrate 1 is provided with PP fuse feed well, PP fuse feed well is connected withspinneret body 2, the PP fuse can eject byspinneret orifice 3, PP fuse feed well has been nested withfilter 6, the outer surface offilter 6 is provided with one deck stainless steel screen pack 7, can effectively remove impurity like this, improve the quality of PP filter core.

Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
