Specific implementation mode

The utility model is described in further detail with reference to the accompanying drawings and embodiments.

Embodiment 1

Referring to Fig.1 ~ 3, the vibrating screen provided in this embodiment for powder screening, including the shell 1 of lower ending opening 1.4, Vibration source, fixing piece and taper sieve, 1 top of shell is feed inlet 1.1, and taper sieve is contacted with the inner wall of shell 1, conical screen Upward, the shell 1 of the online side of conical screen is arranged with material clean-up port to the cone of net, and material clean-up port is equipped with and renovates 2.

It is installed with articulated section 1.2 on the shell 1, renovates 2 and is connect in articulated manner with articulated section 1.2.

The taper sieve is spliced by two pieces of flat-surfaced screens 3, and stitching portion is connected threadably by angle steel 4 It connects.4 both ends of angle steel are welded on the inner wall of shell 1.

The corner of the flat-surfaced screen 3 is folded upward to form bending part 3.1, and the bending angle of bending part is 90 degree.

The vibration source is the pneumatic vibrator 5 for sticking in 1 outside of shell.

The fixing piece is spring base 6, and 6 center of spring base is equipped with the opening for accommodating shell 1, and opening surrounding is installed with Spring 6.1, for 6.1 other end of spring against support angle steel 7, support angle steel 7 is welded on 1 outside of shell.

The operation principle and using method of the present embodiment：

In the confined space in shell 1, the sieve than plane is compared, using the sieving area bigger of taper sieve.It is small Granule materials are drawn off by taper sieve from the opening 1.4 of 1 lower end of shell；Due to taper sieve cone upward, large particle Material is trapped in conical screen side on the net, and is slid to the lower of taper sieve under its own gravity, is deposited in taper sieve and shell 1 Inner wall contact site, during this into, large granular materials are guided to the both sides of taper sieve, the mesh in center will not be caused stifled Plug.Opening renovates 2, you can is cleared up the large granular materials of accumulation by material clean-up port.

The taper sieve is spliced by two pieces of flat-surfaced screens 3, and stitching portion is removably connected by angle steel 4, Opening renovates 2, can further two pieces of flat-surfaced screens 3 be dismantled and be taken out from angle steel 4, convenient for the further clear of flat-surfaced screen 3 It washes or replaces.

The corner of the flat-surfaced screen 3 is folded upward to form bending part 3.1, when taking out flat-surfaced screen 3, can prevent Large granular materials are fallen from the edge of flat-surfaced screen 3, fall into the opening 1.4 of 1 lower end of shell, the small particle completed with screening Material mixing.

Vibration source is used as using pneumatic vibrator 5, it is not only safe but also energy saving compared with traditional motor, and its small, event Barrier is few, and installation and maintenance are simple, phenomena such as exudation without machine oil, the machine oil of exudation is avoided to be snapped down to what screening was completed along shell 1 In small particles material.

Fixing piece uses spring base 6, is supported to shell 1 by spring 6.1, when vibrosieve, can allow for shell 1 With certain offset, and under the reply force-fitting of spring 6.1, vibration is more abundant, short grained screening more book Smoothly.

Embodiment 2

With reference to Fig. 4, what embodiment 2 provided is used for the vibrating screen of powder screening and the difference is that only for embodiment 1：

The fixing piece is steel wire 8, and 1 outside of shell is welded with lifting lug 1.3, and shell 1 is suspended on steel wire 8 by lifting lug 1.3 On.

The operation principle and using method of the present embodiment：

Embodiment 2 and the working method of embodiment 1 are essentially identical, differ only in and use steel wire 8 as fixing piece, similarly Also can allow for shell 1, with certain offset, is a kind of alternative of embodiment 1 in vibration.
