Abstract

The utility model relates to a filter, which is composed of a main body with a barrel-shaped chamber, and a filter screen barrel which is arranged in the barrel-shaped chamber. The utility model is arranged on production lines of macromolecule materials such as plastic, chemical fiber, etc., and products of the macromolecule materials, and is used for filtering and separating impurities in raw materials and homogenizing each component of the raw materials. The utility model has the advantages of big filtering area, easy and safe operation for filter screen change.

Description

Cross cylinder type filter for extrusion press

The utility model relates to a kind of filter, is contained in the downstream of extruder on macromolecular materials such as plastics, chemical fibre and the production of articles line thereof, is used in isolated by filtration impurities in raw materials and each component of homogenizing raw material.

This type of filter of nowadays working on production line can be divided into flat and the two classes garden cartridge type substantially.Flat major defect is that filter area is little, efficient is poor, increasing area simply makes its pressure increase again, the intensity of material is difficult to guarantee, made the garden cartridge filter in order to increase area raising filter efficiency, SJ-80 * 25 of producing as Changzhou plastics machinery head factory are the one example, it is to adorn a screen tube longitudinally in cylindrical main body, and the chamber in the main body is divided into inside and outside two parts, and exocoel leads to charging aperture, inner chamber leads to discharging opening, this filter has improved the efficient of filtering, but major defect is arranged, and bottom, filter screen hole is stressed to be needed greatly with a plurality of king-bolt lockings, the dismounting effort is time-consuming during draping, and easily scalds the workman; The interior residual a lot of raw materials of main cavity both wasted raw material during draping, clean out these high temperature raw materials, and were promptly time-consuming, also slatterned many raw material, had danger again.

The purpose of this utility model is to disclose a kind of existing big filter area, easily changes dismounting again, must manually not clean the filter that vestibule is exempted labourer's danger.

The horizontal garden of a kind of extruder cartridge filter, by the band cylindrical chamber main body and place the screen tube in chamber to constitute, the diameter in screen tube two base external diameters and chamber is same, and the barrel external diameter of porous is less than the footpath, chamber, and barrel is divided into interior two parts of exocoel with the chamber, charging aperture communicates with exocoel, it is characterized in that charging aperture and discharging opening are coaxial, the cylindrical chamber of main body is coaxial with screen tube, the axis normal of charging aperture axis and screen tube, there is interface at the middle part of filter screen barrel, and inner chamber footpath interface and discharging opening are linked up.

Raw material enters exocoel from charging aperture during work, filter through the filter screen barrel again and enter inner chamber, after interface flows to outlet, lead in the equipment of subsequent processing and go, the whole barrel that almost is covered with screen tube because of filtering surface of the present utility model, area is big, the efficient height, the horizontal screen tube of placing, the right and left symmetry, overall stressed cancelling out each other, only the inwall of some thrust at main cavity arranged to the charging aperture direction, only just the next with several stove bolts fixed, needn't lock with king-bolt, so easy disassembling.Screen tube is pulled out from left to right by screw rod (or hydraulic cylinder) during draping, because of the external diameter of screen tube bottom surface is identical with the main cavity diameter, so clout in the chamber all can be scraped (there is self-cleaning in the chamber), does not need artificial clear chamber, saving of work and time and avoid scalding dangerous.

To contrast accompanying drawing below and further describe by embodiment.

Description of drawings:

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is the A-A profile;

Fig. 3 is the side view of correlation technique (vertically garden cartridge filter).

Arrow is represented the materials flow direction among the figure.

Embodiment: main body 2 and the screen tube 3 that is contained in its garden cylindrical cavity constitute a horizontal garden cartridge filter, chamber, the garden sliding fit of two bottom surfaces and main body about screen tube, barrel external application filter screen, diameter is slightly less than the diameter of bottom surface, the chamber of main body is divided into inner chamber 10, exocoel 11, charging 1 communicates with exocoel 11, there is interface 12 at filter screen barrel middle part, and inner chamber 10 is linked up through interface 12 and discharging opening 9.For screen tube interface 12 and tube chamber, main body garden discharging opening are accurately located, be provided with slide guide location-plate 4 and bolt 8.Also be provided with slide guide pole 5, outer support plate 6 and threaded rod 7 for push-and-pull is convenient, the turn threaded rod can be pulled out screen tube from left to right during the draping of oil cylinder piston bar, pulling out screen tube has self-cleaning action to the chamber, garden of main body, does not need clear chamber can will take screen tube that dirty net 13 applies new net off and packs in the chamber.

Claims

1, the horizontal garden of a kind of extruder cartridge filter, by the band cylindrical chamber main body and place the screen tube in chamber to constitute, screen tube two base external diameters are identical with the diameter in chamber, and the barrel external diameter of porous is less than the footpath, chamber, and barrel is divided into two parts in inside and outside chamber with the chamber, charging aperture communicates with exocoel, it is characterized in that charging aperture and discharging opening are coaxial, the shape chamber of main body is coaxial with screen tube, the axis normal of charging aperture axis and screen tube, there is interface at the middle part of filter screen barrel, and inner chamber footpath interface and discharging opening are linked up.
