Abstract
The invention belongs to the technical field of extruding machines, and provides an air exhausting device of an extruding machine. The air exhausting device comprises a vacuum pumping device connected with the extruding machine, wherein a filtering device is arranged between the extruding machine and the vacuum pumping device; the filtering device comprises a shell, and the two sides of the shell are provided with an air inlet for connecting with the extruding machine and an exhaust port connected with the vacuum pumping device; the shell is internally provided with a baffle for preventing a material from entering into an air exhausting pipeline, and an airflow channel is arranged between the baffle and the shell. When the air exhausting device of the extruding machine of the embodiment of the invention performs exhaustion, the material which enters into the filtering device can not enter into the air exhausting pipeline because of the material-blocking action of the baffle, so a problem that the air exhausting pipeline is blocked is effectively solved.
Description
Technical field
The invention belongs to the extruder technology field, relate in particular to a kind of extruder exhaust apparatus.
Background technology
At present, extruder, in the extrusion modling process, if material produces in heating process moisture content and lower-molecular substance are discharged not in time, can badly influence the quality of finished product.Usually on extruder barrel, be provided with exhaust outlet, exhaust outlet is connected with vavuum pump by gas exhaust piping.
But in process of production, material is in half plastifying state, under the air-extraction function of vavuum pump, make material also can partly flow in gas exhaust piping simultaneously, cause obstruction and the pollution of gas exhaust piping, and the gas exhaust piping cleaning is very difficult, cut off complete equipment and clear up gas exhaust piping, causes producing continuously.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of extruder exhaust apparatus, to solve partial material, flows into the technical problem that gas exhaust piping causes gas exhaust piping to stop up.
The embodiment of the present invention is to realize like this, the extruder exhaust apparatus, comprise the vacuum extractor that is connected with described extruder, between described extruder and described vacuum extractor, be provided with filter, described filter comprises housing, described housing both sides be provided be used to the air inlet that connects described extruder be used to being connected the exhaust outlet of described vacuum extractor, described enclosure interior is provided be used to stopping that material enters the baffle plate of discharge duct, between described baffle plate and described housing, is provided with gas channel.
As a kind of improvement, described housing bottom is provided with discharge gate, and described discharge gate is arranged between described baffle plate and described air inlet.
As further improvement, described housing is provided with vacuum meter, and described vacuum meter is corresponding with described exhaust outlet position.
As further improvement, described filter parallel connection is provided with two, between each described filter and described extruder, is equipped with a valve.
the extruder exhaust apparatus that the embodiment of the present invention provides, owing to comprising the vacuum extractor that is connected with described extruder, between described extruder and described vacuum extractor, be provided with filter, described filter comprises housing, described housing both sides be provided be used to the air inlet that connects described extruder be used to being connected the exhaust outlet of described vacuum extractor, described enclosure interior is provided be used to stopping that material enters the baffle plate of discharge duct, between described baffle plate and described housing, be provided with gas channel, thereby when exhaust, backgauge effect due to baffle plate, the material that enters filter can't enter in gas exhaust piping by baffle plate, efficiently solve the problem that gas exhaust piping stops up.
Because described housing bottom is provided with discharge gate, described discharge gate is arranged between described baffle plate and described air inlet, thereby can will enter the material discharge of filter from discharge gate, has avoided the waste of material.
Because described housing is provided with vacuum meter, described vacuum meter is corresponding with described exhaust outlet position, thereby can find in time whether filter needs discharge.
Because described filter parallel connection is provided with two; between each described filter and described extruder, be equipped with a valve; thereby when vacuum meter shows 0; can close one of them valve; opening its corresponding discharge gate clears up corresponding filter; can not cause shutdown, guarantee the continuous production of complete equipment, improve production efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure, 1, extruder, 2, vacuum extractor, 3, filter, 31, housing, 32, air inlet, 33, exhaust outlet, 34, baffle plate, 35, gas channel, 36, discharge gate, 37, vacuum meter, 38, valve.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
as shown in Figure 1, the extruder exhaust apparatus, comprise the vacuum extractor 2 that is connected with extruder 1, vacuum extractor 2 can be vavuum pump, between extruder 1 and vacuum extractor 2, be provided with filter 3, filter 3 comprises housing 31, housing 31 both sides are provided with for the air inlet 32 of connecting extruder 1 and exhaust outlet 33 be used to being connected vacuum extractor 2, housing 31 inside are provided be used to stopping that material enters the baffle plate 34 of discharge duct, between baffle plate 34 and housing 31, be provided with gas channel 35, housing 31 bottoms are provided with discharge gate 36, discharge gate 36 is arranged between baffle plate 34 and air inlet 32, housing 31 is provided with vacuum meter 37, vacuum meter 37 is corresponding with exhaust outlet 33 positions.
Filter 3 parallel connections are provided with two, between each filter 3 and extruder 1, are equipped with a valve 38.
the extruder exhaust apparatus that the embodiment of the present invention provides, owing to comprising the vacuum extractor 2 that is connected with extruder 1, between extruder 1 and vacuum extractor 2, be provided with filter 3, filter 3 comprises housing 31, housing 31 both sides are provided with for the air inlet 32 of connecting extruder 1 and exhaust outlet 33 be used to being connected vacuum extractor 2, housing 31 inside are provided be used to stopping that material enters the baffle plate 34 of discharge duct, between baffle plate 34 and housing 31, be provided with gas channel 35, thereby when exhaust, backgauge effect due to baffle plate 34, the material that enters filter 3 can't enter in gas exhaust piping by baffle plate 34, efficiently solve the problem that gas exhaust piping stops up.
Because housing 31 bottoms are provided with discharge gate 36, discharge gate 36 is arranged between baffle plate 34 and air inlet 32, thereby can will enter the material discharge of filter 3 from discharge gate 36, has avoided the waste of material.
Because housing 31 is provided with vacuum meter 37, vacuum meter 37 is corresponding with exhaust outlet 33 positions, thereby can find in time whether filter 3 needs discharge.
Because filter 3 parallel connections are provided with two; between each filter 3 and extruder 1, be equipped with a valve 38; thereby when vacuum meter shows 0; can close one of them valve 38; opening 36 pairs of corresponding filters 3 of its corresponding discharge gate clears up; can not cause shutdown, guarantee the continuous production of complete equipment, improve production efficiency.
