Abstract

The utility model discloses a device disposing powder iron impurities and the device uses an iron-aluminum sleeve which is equipped with a magnet to replace an original steel pipe line. The device disposing the powder iron impurities changes the fact that the original pipeline only has a transporting function. When dry mixed materials pass through a modified pipeline, the iron impurities in the dry mixed materials can be all adsorbed on the inner wall of an iron pipe under the influence of a magnet field of the magnet inside the iron-aluminum sleeve, and therefore the iron impurities in the dry mixed materials entering a subsequent working procedure is avoided. Therefore, problems that an intermediate bin rotary valve is damaged, material is run out, a screw of an extruder is damaged and scraped, a die is damaged, quality of a product is affected and the like are avoided, product percent of pass can be obviously improved, and manufacturing cost can be obviously reduced.

Description

Process powder iron tramp device

Technical field

The utility model relates to knot screen, more specifically says a kind of iron tramp device of processing in the powder, is used for improving the quality problems that section bar is produced used dry blend.

Background technology

In not plasticized polyvinyl chloride section bar production process, need with polyvinyl chloride resin and various additives by the prescription requirement measure mix after, the dry blend that mixes is distributed into again is dry mixed in the holding vessel, send into by spring conveyer in the hopper of extruder, clamp-on extruder by metering screw, in extruder barrel through the heating, shear extrusion is mixed, fully extrude from extruding dies after the plasticizing, enter the vacuum cooled shaping platform, make section bar fully and stock mould be affixed, to meet the requirements of size, draw through hauling machine, after fixed length mensuration, cut off by cutting machine, through putting in storage after the assay was approved.

But because the raw material types of using in the production not plasticized polyvinyl chloride section bar is more; mix and extrude operation through multiple tracks again; iron tramp often can appear containing in the dry blend; cause the intermediate bin rotary valve to damage, carry fracture, the extruder screw damage is scrapped, mould damages or affect the problems such as product quality continuous appearance, make that product percent of pass is low, production cost can be in any more.

Summary of the invention

The purpose of this utility model provides processes powder iron tramp device, with avoid carry and production process in occur that the damage of intermediate bin rotary valve, fracture, extruder screw damage are scrapped, mould damage or affect the generation of the problems such as product quality.Make constant product quality and reduce production costs.

Technical solution of the present utility model is: a kind of processing powder iron tramp device, comprise base (1), iron pipe (2), and iron pipe (2) outer wall is provided with aluminium sleeve (3), is provided with strong magnets (4) between iron pipe (2) and aluminium sleeve (3).

The utility model replaces original steel conduit with iron aluminium sleeve pipeline, is applicable to the dry blend course of conveying.Have following features:

1, the utility model is to carry part of dry blend pipeline, is to have done local improvement on the basis of original structure, and therefore investment is less.

Do not change original process route when 2, using, do not affect original operating efficiency.

3, result of use is obvious, can thoroughly stop the iron tramp in the dry blend, has avoided the variety of issue that causes because of iron tramp.

4, dismounting and cleaning is convenient, only needs during periodic cleaning this little segment pipe and original junction are dismantled, and gets final product at the iron pipe inner wall cleaning with the specific purpose tool of making, and is convenient, fast.

Description of drawings

Accompanying drawing is overall structure schematic diagram of the present utility model.

The specific embodiment

As shown in drawings, a kind of processing powder iron tramp device comprises base 1, iron pipe 2, and iron pipe 2 outer walls are provided with aluminium sleeve 3, are provided with strong magnets 4 between iron pipe 2 and aluminium sleeve 3.Original steel conduit cuts 550mm above the manually-operated gate of finished bin leading to from transitional storehouse, change the iron pipe 2 of Φ 90 into, make the Φ 120 aluminium sleeves 3 that length is 400mm at iron pipe 2 outer walls, fill Φ 25 strong magnets 4 and fix with nut at aluminium sleeve 3 inwalls, the every circle of aluminium sleeve 3 inwalls can fill 11 strong magnets 4, fills altogether 16 circles.Upper end and the steel for pipe pipe of being connected connect folder and connect, the lower end be connected the flange connection.The utility model is used for the course of conveying of dry blend, dry blend is in by this segment pipe course of conveying after the repacking during use, at the strong magnetic of magnet after the match, iron tramp in the dry blend all can be adsorbed on the iron pipe inwall, Ex-all the iron tramp in the dry blend, and then avoided intermediate bin rotary valve damage, fracture, the extruder screw damage is scrapped, mould damages or affect the problems such as product quality continuous appearance, can significantly improve product percent of pass, obviously reduce production costs.

Claims (1)

1. process powder iron tramp device for one kind, comprise base (1), iron pipe (2), it is characterized in that: iron pipe (2) outer wall is provided with aluminium sleeve (3), is provided with strong magnets (4) between iron pipe (2) and aluminium sleeve (3).
