Description
Technical field
The present invention relates to the filter technology field of plastics machinery, especially a kind of double filter screen circular plate type net-changing device of not shutting down.
Background technology
In plastics machinery, filter also is a critical component, plastic raw materials enters filter net device after extruding through the extruder heating spiral rod, because the plastic raw materials overwhelming majority can not adopt brand-new material article of manufacture, need add various auxiliary materials in process of production, as the color material, modification agent etc., also can add a certain proportion of recovery cycle stock in the plastics that can be recycled, because the impurity that contains in these auxiliary materials is more, containing impurity in the extruded product can influence the post-production and the use of product, filter makes material obtain filtering, and can improve the mixed effect of material, so filter has become necessary part.Because the particularity of the production of plastic raw materials; extruding raw material, spray silk or going out in the membrane process; need to be formed the goods of different shape by mould, and all need not shut down use through being heated into molten condition; the clean pressure that screen pack produced is less; if impurities more for a long time in the plastic raw materials, filter screen takes place to stop up over pressure and cause danger, along with the increase of pressure; it is many that amount of impurities in the plastics of being held back on the screen pack just becomes, thereby block screen pack.Therefore after filter screen blocks, should in time change filter screen, must shut down when changing filter screen, when changing the screen pack that blocks.The quantity-produced later process is brought influence, and shutdown need heat again after changing the filter screen reparation, reenter later process, wastes energy, produces substandard products, causes waste.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the deficiencies in the prior art, the invention provides a kind of double filter screen circular plate type net-changing device of not shutting down, adopt two filters in parallel to realize not shutting down the draping operation, satisfy continuous production requirement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of double filter screen circular plate type net-changing device of not shutting down; comprise filter cylinder shell and the filter that is arranged in the filter cylinder shell inner cavity; described filter comprises filter screen plectane and the roll-over that is used for holding by the fluid of filter screen plectane; several through holes evenly distribute on the filter screen plectane; the skin of filter screen plectane is coated with screen pack; be arranged in parallel the standby each other filter of two covers in the inner chamber of described filter cylinder shell; has the font of falling T feed cavity between the described two sets filtering device; the ends of two shoulders of the described font of falling T feed cavity are tightly connected with the filter screen plectane of two sets filtering device respectively; two sets filtering device all has the discharging chamber; described two discharging chambeies interconnect and merge into a discharge end; the junction of the font of falling T feed cavity is equipped with the import reversal valve, and the outlet reversal valve is installed on the discharge end.
For making reversal valve be convenient to operation, described import reversal valve includes reversing valve core and pedestal is installed with the outlet reversal valve, pedestal is installed is fixed on the filter cylinder shell, and reversing valve core has external part, and described external part passes the installation pedestal and extend out to outside the filter cylinder shell.
For the ease of changing filter screen plectane and the screen pack in the filter, have the end cap of filter on the described filter cylinder shell, described end cap is by being bolted on the filter cylinder shell.
Be connected with exterior line for convenience, also have charging aperture that communicates with feed cavity and the discharging opening that communicates with discharge end, described charging aperture and discharging opening all have and exterior line flange connecting pipe.
The invention has the beneficial effects as follows; the double filter screen circular plate type net-changing device of not shutting down of the present invention adopts the two sets filtering device that is arranged in parallel; realize not shutting down the replacing filter by regulating the import reversal valve and exporting reversal valve; need not regulate any operation of filter during replacing; input and output material does not have significant change; thereby guarantee the later process operate as normal; reduce the generation of substandard products; shutdown operation is not enhanced productivity; energy savings; save time, save material, the detachable back of filter net device that is in the state of quitting work is changed or is cleaned.
