Description
Technical field
The utility model relates to plastics, chemical fibre, rubber, colloidal sol device for filtering impurities, especially relates to a kind of macromolecule melt filter.
Background technology
In the macromolecular materials such as most plastics, chemical fibre, rubber, colloidal sol more or less all contain different impurity, these impurity can reduce the quality of shaped article and the qualification rate of finished product greatly, especially to the shaping finished product of having relatively high expectations; These impurity also can exert an adverse impact to production equipment simultaneously, as reduced production efficiency, the service life etc. of equipment.Therefore must be before production and the machine-shaping of product molding finished product, by heating raw materials to molten condition, under extrusion equipment or pressurized equipment, through filter equipment, its impurity is filtered out, the raw material that makes it to be purified, thus improve the quality of shaped article and expand range of application.
Pattern with regard to filter (net-changing device) is in the market more; there are single double-plate quick net-changing device, single Double-plunger, net belt type, rotating disc type, endless wire changer etc.; all there is the draping ability of not shutting down online; but except net belt type has artificial draping of long period; the draping cycle of the filter of all the other patterns is all shorter; especially in the time filtering dirtier reclaimed materials; the draping cycle is more of short duration, frequent; the more bothersome effort of draping sheet; also more to the fluctuation of output material stream; sometimes also there will be the discontinuity of production, affect the whole production process of product.And net belt type filter, though there is the longer draping cycle, walking net is that inner portion material presses driving guipure to walk net LAP, but the length of walking net in actual application process is uncertain, walk to net unstable, and the phenomenons such as net, card net, suspension are not walked in existence often, selection requirements to filter screen is higher, need to walk to net time, walk the net cycle also longer, output flow is reduced, reduce production efficiency, also can increase the duration of load application of extrusion equipment in the time needing draping simultaneously, thereby increase energy consumption, reduces service life.
Summary of the invention
The utility model object is to provide that a kind of draping is stable, not suspension, does not block the macromolecule melt filter of net.
For achieving the above object, the utility model can be taked following technical proposals:
Macromolecule melt filter described in the utility model, comprises frame, is arranged on the electric heater unit in described frame, is horizontally disposed with the melt canal with import and export in described electric heater unit; Described melt canal is made up of feed cavity and discharging chamber, in melt canal between described feed cavity and discharging chamber, be vertically installed with reciprocal web plate and screen pack, described reciprocal web plate and screen pack both sides are respectively by network access sealing device with go out net sealing device sealing and extend electric heater unit outside, and described reciprocal web plate one end is connected with the hydraulic rod end of hydraulic jack; The uniform barb groove that offers on described reciprocal web plate and screen pack contact-making surface; In described feed cavity, be provided with pressure sensor.
In described frame, be provided with limit switch, on described network access sealing device, be provided with filter screen sensor; Be provided with storage tape drum in frame one side, described screen pack one end is placed in described storage tape drum.
The utility model advantage is simple in structure, easy to control, easy to operate, and automaticity is high.Can not shut down continuously draping, draping is simultaneously stable, all permanent, and without the fluctuation of material stream, not suspension, does not block net, not high to the quality requirement of net, Increasing Production and Energy Saving; Without waste material, reduce work, time saving and energy saving, reduce production costs, withstand voltage height, does not leak material.

Detailed description of the invention
As shown in Figure 1, 2, 3, macromolecule melt filter described in the utility model, comprises frame 1, is arranged on the electric heater unit 2 in described frame 1, in described electric heater unit 2, is horizontally disposed with the melt canal with import and export; Described melt canal is made up of feed cavity 3 and discharging chamber 4, in melt canal between described feed cavity 3 and discharging chamber 4, be vertically installed with reciprocal web plate 5 and screen pack 6, the both sides of described reciprocal web plate 5 and screen pack 6 are respectively by network access sealing device 7 with go out 8 sealings of net sealing device and extend electric heater unit 2 outsides, and described reciprocal web plate 5 one end are connected with hydraulic stem 10 ends of hydraulic jack 9; The uniform barb groove 11 that offers on described reciprocal web plate 5 and screen pack 6 contact-making surfaces; In described feed cavity 3, be provided with pressure sensor 12; In described frame 1, be provided with limit switch, on described network access sealing device 7, be provided with filter screen sensor; Be provided with storage tape drum 13 in frame 1 one sides, described screen pack 6 one end are placed in described storage tape drum 13.
When work: macromolecule melt filter inlet end is connected with melt extrusion equipment or pressurized equipment delivery outlet, outlet connects corresponding subsequent production equipment; Screen pack 6 in storage tape drum 13 is extracted out, penetrated interior the going out net sealing device 8 and stretching out 20mm to right side of net groove of the network access sealing device 7 in electric heater unit 2 left sides; When melt enters feed cavity 3 at the state of certain pressure from import, to discharging chamber 4 and from outlet output, be clean material through screen pack 6, reciprocal web plate 5; Along with the passing of working time, the impurity before screen pack 6 can slowly increase, and the filter effect of screen pack 6 declines, and the pressure in feed cavity 3 will raise, and when being greater than after the setting pressure value of pressure sensor 12, will carry out draping by control system--walk net.
When draping, the hydraulic stem 10 of hydraulic jack 9 drives reciprocal web plate 5 to move right the given stroke place to limit switch, meanwhile because screen pack 6 and reciprocal web plate 5 are pressed and back and forth on web plate 5 under the effect of barb groove 11 at import material, the two is tightly sticked together, thereby make screen pack 6 force together to move right with reciprocal web plate 5.The length of once walking net can realize by the position that regulates limit switch; After walking to net, change the new net of certain length, the pressure drop of feed cavity 3, back and forth web plate 5 resets, wait for the beginning of draping next time, in the time that the screen pack 6 (10 meters, 20 meters) in storage tape drum 13 is finished, the filter screen sensor being arranged on network access sealing device 7 sends alarm signal, and notice is installed draping.
