The material loading knot screen of three-dimensional stereo grating material extruder
Technical field
The utility model relates to three-dimensional stereo grating material extruder, is the material loading knot screen of three-dimensional stereo grating material extruder specifically.
Background technology
At present, suction is generally adopted in the charging of extruder in process of production, and it sucks particulate material in the hopper.Because be mingled with the impurity such as part dust in the particulate material, dust is inhaled into hopper in the process of suction, if do not remove impurity, will affect product quality.Existing knot screen generally is by flexible pipe blower inlet directly to be connected with the outlet of hopper, when particulate material sucks air blast with impurity by flexible pipe when sucking hopper, is then discharged by air blast.This mode not only easily causes air blast to be blocked by impurity, and impact is normally produced; And when the cleaning air blast, waste time and energy.
The utility model content
The utility model has solved above-mentioned technical problem, provides impurity-eliminating effect better and is convenient to clear up the material loading knot screen of the three-dimensional stereo grating material extruder of impurity.
For above-mentioned technical problem, the technical solution adopted in the utility model is: the material loading knot screen of three-dimensional stereo grating material extruder, comprise air blast and the extruder hopper that is provided with material inlet, be provided with a filter screen at described import upside, this filter screen upside forms the impurity outlet, this outlet is communicated with a trash separator, and this trash separator is communicated with the air inlet of described air blast.
The utility model also has following additional technical feature:
Described trash separator comprises a cylindrical shell, and a filter core with inner chamber is installed in this cylindrical shell, forms exocoel between cylindrical shell and the filter core; Described exocoel is communicated with described outlet, and described inner chamber is communicated with described air inlet.
Described filter core is installed in the cylindrical shell by bolt.
As can be known from the above technical solutions, the utility model can be removed a part of impurity by filter screen, utilizes the filter core in the trash separator to remove a part of impurity again, so that it is few to enter the interior impurity of air blast, not only be difficult for stopping up air blast, and impurity-eliminating effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model optimal way.
The specific embodiment
Describe the utility model in detail below in conjunction with Fig. 1:
This material loading knot screen comprises air blast 1 and is provided with the extruder hopper 2 of material inlet 21, be provided with a filter screen 3 at described import 21 upsides, these filter screen 3 upsides form impurity outlet 22, material can be exported from the filter screen downside, described outlet 22 is communicated with a trash separator 4, and this trash separator 4 is communicated with the air inlet 11 of described air blast 1.Under the effect of air blast, a part of impurity absorption has been removed the partial impurities in the material on filter screen.
Trash separator 4 of the present utility model comprises a cylindrical shell 41, and a filter core 42 with inner chamber 421 is installed in this cylindrical shell 4, forms exocoel 411 between cylindrical shell 41 and the filter core 42; Described exocoel 411 is communicated with described outlet 22, and described inner chamber 421 is communicated with described air inlet 11.In implementation process, described filter core 42 is installed in the cylindrical shell by bolt, be convenient to clear up after the dismounting, but also pass-through mode is installed, and just can as long as guarantee that filter core is quick detachable.In when work, enter the exocoel of trash separator from the gas of hopper outlet output, gas enters inner chamber from exocoel through filter core, then enters the air inlet of air blast, discharges from air blast.Like this so that a part of impurity absorption on filter core, is further removed impurity.From the above, not only structure is simple for the utility model, good impurity removing effect, and filter core is convenient to dismounting, and is time saving and energy saving during cleaning impurity.
Above-mentioned embodiment is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
