Description
Technical field
The utility model belongs to the filter plant technical field, relates to a kind of extruder exhaust gas filtering system.
Background technology
Existing modifying plastics industry all adopts vacuum system to take out the analyte of macromolecular material in the plastics melting process (lower-molecular substance), improves the presentation quality and the plastic material physical property of plastic pellet.
Simpler and cruder filtering tank is adopted in present most of factory commercial city, filters like horizontal expanded metal lath formula cylinder, has used 2 hours and will stop up; To take half an hour during cleaning net formula cylinder, and will use baked wheaten cake, in case distortion is a little arranged; The filter screen that must more renew is quite wasted time and energy.Even more serious is that lower-molecular substance can arrive all pipelines in the whole system through this simple and easy filter, in case cooling; Will solidify, stop up system pipeline, not only influence the use of other board; And will cut off all production lines and clear up all pipelines, just can resume production.This can cause serious stopping accident.
The utility model content
The utility model technical problem to be solved is the blocking problem that the existing filter that the analyte of macromolecular material in the plastics melting process is filtered causes entire equipment easily, and to this problem a kind of extruder exhaust gas filtering system is provided.
The utility model solves the problems of the technologies described above through following technical scheme:
A kind of extruder exhaust gas filtering system; Comprise filter element that is connected with the extruder exhaust outlet and the vacuumizing part that is connected with filter element; It is characterized in that said filter element comprises coarse filtration mechanism and the thin filter mechanism that is connected with the extruder exhaust outlet, coarse filtration mechanism is connected with vacuumizing part through thin filter mechanism.
The analyte of said macromolecular material contains lower-molecular substance not of uniform size usually; And the filtering tank that the background technology part is introduced only carries out disposable filtration to the analyte (lower-molecular substance) of said macromolecular material; The filter screen that is adopted often can't all possess good filter effect to all lower-molecular substances; Cause the analyte of part macromolecular material to reach in the pipeline of other equipment, have a strong impact on the operate as normal of equipment through filtering tank.
Thus, the filter element in the said a kind of extruder exhaust gas filtering system of the utility model comprises coarse filtration mechanism and the thin filter mechanism that is connected with the extruder exhaust outlet, and coarse filtration mechanism is connected with vacuumizing part through thin filter mechanism.
Individual bigger lower-molecular substance can obtain filtering through coarse filtration mechanism, and individual less lower-molecular substance can obtain filtering through thin filter mechanism, thereby can guarantee to obtain good filter effect on the whole.
The utility model has also adopted following technical scheme:
Said coarse filtration mechanism comprises that inside is provided with the filtering tank of baffle plate, and said filtering tank top is provided with import that connects the extruder exhaust outlet and the outlet that connects thin filter mechanism, and said baffle plate is provided with filtering holes;
Said filtering tank bottom is provided with sewage draining exit;
Thin filter mechanism comprises that at least two inside are provided with the thin filtering tank of steel wool, and said thin filtering tank top is provided with the bleeding point that connects vacuumizing part, and said thin filtering tank is provided with the import that connects coarse filtration mechanism;
Said import is provided with valve;
Said thin filtering tank bottom is provided with sewage draining exit.
Description of drawings
Fig. 1 is the structural representation of the said a kind of extruder exhaust gas filtering system of embodiment.
The specific embodiment
Embodiment
See Fig. 1; A kind of extruder exhaust gas filtering system; Comprise filter element that is connected with the extruder exhaust outlet and the vacuumizing part that is connected with filter element; Said filter element comprises coarse filtration mechanism and the thin filter mechanism that is connected with the extruder exhaust outlet, and coarse filtration mechanism is connected with vacuumizing part through thin filter mechanism.
Guarantee to obtain the design object of good filter effect on the whole for better realization; With regard to coarse filtration mechanism; This mechanism comprises filtering tank 4, and filtering tank 4 tops are provided with inlet tube 1 and the outlet 3 that connects the extruder exhaust outlet, are equipped with ball valve and vacuum meter 2 on inlet tube 1 and the outlet 3; Be provided with the baffle plate 5 that has filtering holes in the filtering tank 4, the size of filter opening can be set according to the size of the material of required filtration.
Individual lower-molecular substance (generally the form with jelly occurs) big and that weight is bigger gets into the bottom of filtering tank 4 through the filtering holes of baffle plate 5 from the gas that extruder is discharged; And blow-off pipe 6 dischargings through being arranged on filtering tank 4 bottoms, the switch of blow-off pipe 6 is by the ball valve control that is arranged on the blow-off pipe 6.
For thin filter mechanism; This mechanism comprises the first thin filtering tank 8 and the second thin filtering tank 11; Be equipped with the steel wool (this figure is not shown) that is used to filter in the said first thin filtering tank 8 and the second thin filtering tank 11; The said first thin filtering tank 8 and the second thin filtering tank 11 are equipped with the inlet tube (7 and 12) that is communicated with filtering tank outlet 3; The said first thin filtering tank 8 and the second thin filtering tank, 11 tops are equipped with the exhaust tube (9 and 10) that is communicated with vacuumizing part, and said inlet tube of this section and exhaust tube are equipped with ball valve.
Why two thin filtering tanks are set; At least be the continuity of having considered the said filtration system work of present embodiment; After filtering a period of time, suppose that the first thin filtering tank 8 need clear up, then operating personnel can close the ball valve that is arranged on the first thin filtering tank inlet tube 7; And use the second thin filtering tank 11 to filter, thereby the operate as normal that can guarantee said filtration system can be interrupted.
Material heavier relatively from the gas that filtering tank outlet 3 is discharged is fallen into tank base along the first thin filtering tank 8 or second thin filtering tank 11 spiral inner walls by the gravity effect, through Blowoff ball valve 13 dischargings that are arranged on tank base.
Then feeding steel wool for relative lighter material filters.
The said filtration system of present embodiment is compared and the described filtering tank of background technology part, has tangible technique effect:
The said filtering tank of background technology part needs cleaning in per 2 hours once, and the thin filtering tank of present embodiment can be cleared up once in 8 hours, and need not shut down, and the said filtering tank of present embodiment then can be cleared up once in 24 hours;
The said filtering tank of background technology part will be put in order factory and shut down one day cleaning system pipeline owing to filtering thoroughly blocking pipe, after the said filtration system of use present embodiment, need not do this work.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
