Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1 and Figure 2, a kind of dust suppression device for development machine, this dust suppression device comprises: mounting base 1, nozzle installing rack 2 and multiple jet element 3.
Wherein, nozzle installing rack 2 is arranged on mounting base 1; Multiple jet element 3 is separately positioned in the top of nozzle installing rack 2.
In the present embodiment, 2-8 jet element 3 is adopted to be arranged in nozzle installing rack 2.
As shown in Figure 3, Figure 4, in the present embodiment, when installing this dust suppression device for development machine, the setting angle scope between mounting base 1 and horizontal plane is 8 °-12 °.
Mounting base 1 is for being fixed on dust suppression device the gusset piece of development machine correct position, and the setting angle between mounting base 1 and horizontal plane is 10 °, and the water smoke allowing multiple jet element 3 spray effectively covers the cutterhead of development machine in the horizontal direction.
As shown in Figure 3, Figure 4, the side of nozzle installing rack 2 is provided with air inlet port 23, water inlet 22.One end of water inlet 22 is connected with water source interface under outer well, and the other end of this water inlet 22 is connected with multiple jet element 3.One end of air inlet port 23 is connected with outer well compressed air interface, and the other end of this air inlet port 23 is connected with multiple nozzle 31 parts 3.
As shown in Figure 2, the head clearance of nozzle installing rack 2 is provided with multiple nozzle installing hole 21.In the present embodiment, be arranged on normal and the horizontal plane of multiple nozzle installing holes 21 of the crown center of nozzle installing rack 2, the angular range between the normal of remaining nozzle installing hole 21 and vertical plane is 6 °-10 °.
In the present embodiment, the angle between the normal of remaining nozzle installing hole 21 and vertical plane is 8 °.
