Evacuation group includes real empty can, valve, filter equipment, intake pipe, blast pipe, fluid -discharge tube and vacuum pump. Real empty can is equipped with air inlet, gas vent and leakage fluid dram, and the air inlet is connected with the intake pipe, the opening and close of valve control air inlet, and the flowing back pipe is connected to the leakage fluid dram, is equipped with filter equipment in the gas vent. The one end run -on gas port of blast pipe, the vacuum pump is connected to the other end. This vacuum pumping system appears under the unusual condition in one of them evacuation group, can select to open another normal evacuation group work, closes unusual evacuation group to maintain, need not stop the extruder in maintaining the engineering, and is convenient high -efficient.
Description
Technical field
The utility model relates to double screw extruder, specifically refers to a kind of pumped vacuum systems of double screw extruder.
Background technology
Double screw extruder is a kind of material blending equipment, and after raw material feeding extruder, fully mixing and extruding under the effect of two screw rods, forms product.This process had both comprised physical reactions and had also comprised chemical reaction, and period can produce the lower-molecular substances such as a large amount of gas and precipitate.If the gas that these physical and chemical reactions produce and precipitate are mixed in the product extruded, the final outward appearance of product and mechanical property can be affected.
In the prior art, double screw extruder generally arranges exhaust outlet and connects vacuum extractor to remove the gas and precipitate that produce in raw material Blending Processes.But the pumped vacuum systems of routine is easily by the precipitate blocking pipe of all kinds of condensation and vavuum pump, affects the effect vacuumized and even cause stopping production, and safeguard and clean pumped vacuum systems and first must stop extruder, waste time and energy.
Utility model content
The purpose of this utility model is for double screw extruder provides a kind of vacuum capability strong, and the pumped vacuum systems for double screw extruder that can safeguard under open state and clean.
The technical scheme realizing the utility model object is: the utility model provides a kind of pumped vacuum systems of double screw extruder, comprise two be connected in parallel with the cylindrical shell of double screw extruder vacuumize group; The described group that vacuumizes comprises vacuum tank, valve, filter, air inlet pipe, blast pipe, discharging tube and vavuum pump; Described vacuum tank is provided with air inlet, exhaust outlet and leakage fluid dram; Described air inlet is connected with air inlet pipe; The keying of described Valve controlling air inlet; Described leakage fluid dram connected drainage pipe; Filter is provided with in described exhaust outlet; One end of described blast pipe connects exhaust outlet, and the other end connects vavuum pump.
The exhaust outlet of described vacuum tank is annular bulge-structure, and its inside is provided with annular shoulder block, and its outer ring is provided with screw thread and forms with blast pipe and is threaded; Described filter is positioned at the exhaust outlet of vacuum tank.
Described filter comprises extexine and is arranged on the interior packed layer in extexine.
The extexine of described filter is metal screen, and interior packed layer is loose porous absorbent material.
The utility model has positive effect: the pumped vacuum systems that (1) the utility model provides comprise two groups of parallel connections independently can carry out the work that vacuumizes vacuumize group, one vacuumizes group when occurring abnormal wherein, can select to open another and vacuumize group work normally, close the abnormal group that vacuumizes and safeguard.In addition on the one hand, when processing the many material of some escaping gas impurity, unlatching two can be selected to vacuumize group and to meet and stronger vacuumize demand.
(2) pumped vacuum systems that the utility model provides comprises filter, can effectively prevent the water of condensation and low molecule impurity from blocking vavuum pump and pipeline.
(4) filter apparatus configuration that provides of the utility model is simple, with low cost, is disposable parts; After completing certain working time, screw off blast pipe and change filter, convenient and swift.
(4) filter that the utility model provides comprises inside and outside two-layer, outer field metal screen, for keeping fixed profile and the size of filter, is convenient to transport, stores and installs, internal layer is absorbing material, for moisture and the low molecule impurity of absorption condensation.
