Through the design, the service life of a single filtering plate can be effectively prolonged, the stopping maintenance frequency can be reduced, the processing efficiency can be promoted, the energy waste can be reduced, the later-period maintenance cost of the filtering machine can be lowered.
Description
Technical field
The utility model relates to a kind of plastic granulating filter, is specially the structure-improved of plastic granulating filter.
Background technology
At present, in plastic processing granulation industry, conventionally adopt and with the filter of screen pack or filter, extruder extrusion plastic is filtered, in above process, particularly for those recycled plastics, because containing a large amount of foreign material in extrusion plastic, be easy to cause blocking even of screen pack or filter to block, need frequently shut down and safeguard, have a strong impact on working (machining) efficiency, shutdown simultaneously can make a large amount of preheated wire drawing raw material in extruder lose efficacy, in the time again starting shooting, the raw material of this partial failure need be taken out and again carry out pre-hot wire drawing, not only troublesome poeration, and can cause a large amount of energy wastes.
Summary of the invention
For the problems referred to above, the utility model has designed a kind of structure-improved of plastic granulating filter, and it can effectively extend the service time of single filter; reduce the frequency of shutting down maintenance; promote working (machining) efficiency, reduce energy waste, reduce the later maintenance cost of filter.
For achieving the above object, the utility model is by the following technical solutions:
A kind of structure-improved of plastic granulating filter, comprise the filter being arranged in frame, it is characterized in that: the discharging opening of some filtering holes of described filter is provided with stress induction device, stress induction device passes to the stress signal being subject in work controller and compares with the preset pressure value in controller; The charge level outside top that goes out of described filter is provided with can go out charge level to whole filter and scrape the scraper of cutting action, and scraper is positioned on vertical movement apparatus, and vertical movement apparatus drives the action of scraper by controller control.
Further, the charge level below that goes out of above-mentioned filter is provided with an aggregate bin, and aggregate bin below is provided with discharge nozzle and is connecting a sundry separating device.
Further, above-mentioned sundry separating device includes a threeway, the upper inlet of threeway is connected with discharge nozzle by upper control valve, in the Horizontal Exit of threeway, be provided with a pressure inductor, pressure signal transmission is given described controller by pressure inductor, and the lower outlet of threeway is by leading directly to ash can after control valve once; The switching of described upper control valve and lower control valve is by controller control.
Further, above-mentioned stress induction device is uniformly distributed on the plate face of filter.
The utility model is provided with some stress induction devices on the discharging opening of filter filtering holes, these stress induction devices will feed back to controller by the stressing conditions of filter in real time, thereby indirectly obtain the stopping state of filtering holes in filter, once the stressed setting value that is greater than of filter, controller will drive scraper to move down the charge level that of filter is scraped and cut, tamper in filtering holes is scraped off, thereby ensure the again unimpeded of filtering holes, effectively extend the service time of single filter, reduce the replacement frequency of filter.
At this, the tamper that scraper scrapes is collected by the aggregate bin that is positioned at filter below, and by the sundry separating device on discharge nozzle, foreign material is discharged in ash can gradually.
To sum up, the utility model carries out scraping of not timing by doctor blade system to filter filtering holes and cuts cleaning, can effectively extend the working time of single filter, promotes working (machining) efficiency, reduces energy waste, alleviates the later maintenance cost of filter.
Brief description of the drawings
Fig. 1, structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of structure-improved of plastic granulating filter, comprise the filter 2 being arranged in frame 1, the discharging opening of some filtering holes 21 of described filter 2 is provided with stress induction device 3, and the stress signal being subject in work is passed to controller 4 by stress induction device 3.
The charge level outside top that goes out of described filter 2 is provided with can go out charge level to whole filter and scrape the scraper 5 of cutting action, and scraper 5 is positioned on vertical movement apparatus 51, and vertical movement apparatus 51 drives scraper to move up and down by controller 4 and controls.
Above controller 4 receives the signal that stress induction device 3 sends in real time, thereby indirectly obtains the real-time stopping state of filtering holes 21 on filter 2.At this, truer for making to obtain data, described each stress induction device 3 is uniformly distributed on filter 2.In use, once local obstruction of filtering holes 21 on filter 2, when the stressed setting value being greater than in controller 4 of filter 2 that stress induction device 3 detects, controller 4 will drive vertical movement apparatus 51 and make scraper 5 scrape and cut operation the charge level that goes out of filter 2, tamper in filtering holes 21 is scraped off, thereby ensure filtering holes 21 again unimpeded, the service time that extends single filter 2 with this, reduce the replacement frequency of filter 2.
The charge level below that goes out of described filter 2 is provided with an aggregate bin 6, and aggregate bin 6 belows are provided with discharge nozzle 61 and are connecting a sundry separating device.In the present embodiment, sundry separating device includes a threeway 71, the upper inlet 711 of threeway is connected with discharge nozzle 61 by upper control valve 72, in the Horizontal Exit 712 of threeway 71, be provided with a pressure inductor 73, pressure signal transmission is given described controller 4 by pressure inductor 73, and the rear straight-through ash can 8 of control valve 74 is passed through in the lower outlet 713 of threeway 71; The switching of described upper control valve 72 and lower control valve 74 is controlled by controller 4.
Under original state, upper control valve 72 is in normally open, lower control valve 74 is in normally off, the tamper that scraper 5 scrapes drops to after aggregate bin 6, because the density of foreign material is greater than plastics, foreign material will sink to gradually aggregate bin 6 bottoms and be dropped in the lower outlet 713 of threeway 71 through upper control valve 72 by discharge nozzle 61, and along with the continuous accumulation of foreign material, once foreign material exceed the pressure inductor 73 on the Horizontal Exit 712 of threeway 71, pressure inductor 73 by transmission of signal to controller 4, controller 4 will send signal and control valve 72 be closed and lower control valve 74 is opened, foreign material in threeway 71 are directly discharged in ash can 8 through the lower outlet 713 of threeway, controller 4 sends signal again afterwards, control valve 72 is opened and lower control valve 74 is closed, again enter refuse collecting state.
To sum up, the utility model carries out scraping of not timing by doctor blade system to filter filtering holes and cuts cleaning, can effectively extend the working time of single filter, promotes working (machining) efficiency, reduces energy waste, alleviates the later maintenance cost of filter.
The above, it is only preferred embodiments of the present utility model, not invention is done to any pro forma restriction, every foundation know-why of the present utility model, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of technical solutions of the utility model.
