The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, shown in Fig. 2 and Fig. 3, fibre material discharger, it comprises housing 1, feed pipe 2 and separator, the upper end of housing 1 is provided with air stream outlet, the lower end of housing 1 is provided with fiber outlet, described housing 1 is by the upper conical portion 3 along direction connects successively from top to bottom, cylindrical portion 4 and lower back taper portion 5 form, air stream outlet is arranged at the upper end of upper conical portion 3, fiber outlet is arranged at the lower end of lower back taper portion 5, described separator comprises the cylindrical shell 6 that is fixedly arranged on housing 1 inside and the obconical 7 that is arranged at cylindrical shell 6 inside, the external diameter on obconical 7 tops equates with the internal diameter of cylindrical shell 6, the top of obconical 7 is fixedly connected with cylindrical shell 6, feed pipe 2 is arranged on the sidewall of housing 1, and feed pipe 2 runs through housing 1 and cylindrical shell 6 successively, feed pipe 2 is tangent with the inner surface of cylindrical shell 6.
The inside of described upper conical portion 3 is provided with back taper inner casing 8, and the top external diameter of back taper inner casing 8 equates with the top internal diameter of upper conical portion 3, and the top of back taper inner casing 8 is fixedly connected with the top of upper conical portion 3.
The top of described back taper inner casing 8 is also provided with the backstop 9 of capping back taper inner casing 8 upper ends.
Described fiber outlet is connected with discharge nozzle 10, discharge nozzle 10 can be bend pipe, straight tube or reducer pipe, as shown in Figure 1, is a kind of structure of discharge nozzle 10, and also can, according to the difference of the equipment of connection discharge nozzle 10, discharge nozzle 10 be set to the structure as shown in Fig. 4, Fig. 5 or Fig. 6.
The course of work of the present utility model is as follows: the air-flow that is mixed with fibre material enters cylindrical shell 6 through feed pipe 2, because feed pipe 2 is tangent with the inner surface of cylindrical shell 6, air-flow is at the interior wall guided backspin stream of cylindrical shell 6, due to the density variation of fiber and air-flow, fibre material falls down along the inwall of cylindrical shell 6, and finally falls into back taper portion 5 inside from cylindrical shell 6 bottoms, and air-flow is along cylindrical shell 6 inwall eddy flows to lower back taper portion 5 inwalls, due to the reflex of lower back taper portion 5 inwalls, air-flow is transferred the annular space to forward spin flow to the outer wall of cylindrical shell 6 and between the inwall of cylindrical portion 4, along annular space toward forward spin flow to upper conical portion 3, the setting of top back taper inner casing 8, the air-flow rising is flowed along housing 1 inwall, and enter in the space between back taper inner casing 8 and housing 1, be subject to after the packing of top, air-flow slows down and is pressed down, thereby be beneficial in air-flow the still whereabouts of residual part fiber, the air-flow being pressed down finally flows out by the top of back taper inner casing 8, the setting of backstop 9 has further intercepted the outflow of fiber, thereby effectively prevent the leakage of fibre material, avoid the waste of resource.
