Fig. 3 is the structural representation that this material screen is chosen device embodiment three.
Among the figure: 1, hopper; 2, housing; 21, material cavity; 22, fine fodder goes out the chamber door; 23, coarse fodder goes out the chamber door; 24, material collection case; 25, perforate; 3, wind power system; 31, air filter; 4, screening net; 5, separation net; 6, material; 7, connecting rod.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Figure 1 shows that this material screen chooses the embodiment one of device, this material screen is chosen device and is comprised hopper 1, housing 2, wind power system 3, screening net 4, separation net 5, connecting rod 7, described hopper 1 is funnel-form, be loaded on described housing 2 tops, the wind-force blowing direction of described wind power system 3 is towards housing 2 inside, described screening net 4 tilts to be loaded on the wind-force blowing direction opposite of wind power system 3, screening net 4 is positioned at hopper 1 below, described housing 2 interior screening nets 4, a material cavity 21 is arranged at the bottom of separation net 5, the next door of described material cavity 21 has the fine fodder that is articulated on the housing 2 to go out chamber door 22, described separation net 5 tops have the coarse fodder that is articulated on the housing to go out chamber door 23, described screening net 4, separation net 5 is made for grid material, and described connecting rod 7 is loaded in the housing 2 and screening net 4, separation net 5 is strained and fixed.
This material screen is chosen device wind screening and grid screening is assembled one, adopt 1 li material that falls of 3 pairs of hoppers of wind power system 6 to carry out wind, with blowing on the screening net 4 of 6 li less particles of material, these material 6 particles are along the 4 inclined-plane landings of screening net, meet seeing through of material 6 requirements and screen net 4, fall in the material cavity 21, and undesirable material 6 will fall on the separation net 4, finish material 6 thick smart screenings.
In the specific implementation, need how much to select according to the specific design blanking size of hopper 1 end opening, select to screen the size of net 4, separation net 5 grids according to the size of material particles, perforate 25 is arranged at the top of housing 2, as shown in Figure 1, the flow pass that this perforate 25 blows for the wind-force of wind power system 3, pore size distribution density is equipped with less than the net of screening net 4 and separation net 5 in this hole, to prevent that material is blown from here, this net will conveniently be taken away, in order to housing 2 inside are operated, come that material is attached to screening net 4 material 6 that can't fall and process.The preferred stainless steel of the material of housing 2, stainless steel has extraordinary antirust function.
