The invention discloses a kind of chemical industry powder sifter, dusting cover device including inverted cone-shaped, dusting cover device is thin-wall member, several small through hole are evenly equipped with dusting cover device, the first cribellum of inverted cone-shaped is provided with dusting cover device, several large through-holes are evenly equipped with first cribellum, the lower end of first cribellum is provided with spacer bar, the lower end of spacer bar abuts with the cone angle of dusting cover device inwall, so that uniform gap is just provided between the outer wall of cribellum and the inwall of dusting cover device, the upper limb of first cribellum overturns to form isolation part outward, and isolation part abuts with the inwall of dusting cover device, and set accommodates oscillation ring on spacer bar.Due to there is the setting of oscillation ring, so just cribellum can be directly vibrated, the industrial chemicals allowed below medium size is fallen into dusting cover device, then the screening of dusting cover device is passed through again, industrial chemicals with regard to final size can be obtained, cribellum power consumption is small at the beginning of being directly vibrated using oscillation ring, and passes through and screen twice, and the situation of plug-hole can be avoided to occur most possibly.The present invention is used for the screening of industrial chemicals.
Description
Technical field
The present invention relates to chemical industry equipment, more particularly to a kind of chemical industry powder sifter.
Background technology
The industrial chemicals granularity of many powderies varies, using preceding needing to be sieved, and the chemical industry of some powderies
Raw material is by prolonged storage or all easy caking that jolts in transit.
In order to tackle case above, chemical plant is often sieved to these industrial chemicals, passes through the side of vibrosieve
Formula separates the small industrial chemicals of the big industrial chemicals of granularity and granularity, and the industrial chemicals of caking is broken up.
But existing sifter power consumption is greatly, is easily occurring the problem of stifled eye during screening.
The content of the invention
The technical problem to be solved in the present invention is：A kind of power consumption chemical industry powder sifter that is small, being avoided that stifled eye is provided.
The present invention solve its technical problem solution be：
A kind of chemical industry powder sifter, includes the dusting cover device of inverted cone-shaped, and dusting cover device is thin-wall member, uniform on dusting cover device
There are several small through hole, the first cribellum of inverted cone-shaped is provided with dusting cover device, several large through-holes, first cribellum are evenly equipped with first cribellum
Lower end be provided with spacer bar, the lower end of spacer bar abuts with the cone angle of dusting cover device inwall so that the outer wall of first cribellum and dusting cover device
Inwall between be provided with uniform gap, the upper limb of first cribellum overturns to form isolation part outward, the inwall of isolation part and dusting cover device
Abut, set accommodates oscillation ring on spacer bar.
As the further improvement of above-mentioned technical proposal, the top edge of dusting cover device overturns to form connecting portion outward.
As the further improvement of above-mentioned technical proposal, present invention additionally comprises upper press ring and lower pressure ring, the top of isolation part
Provided with crimping plane, the inward flange of upper press ring down overturns to form trim ring, and upper trim ring abuts with crimping plane, and upper press ring is with
Pressure ring is clipped between connecting portion, and upper press ring is bolted together with lower pressure ring.
The beneficial effects of the invention are as follows：A kind of chemical industry powder sifter, includes the dusting cover device of inverted cone-shaped, and dusting cover device is thin
Wall member, several small through hole are evenly equipped with dusting cover device, the first cribellum of inverted cone-shaped is provided with dusting cover device, is evenly equipped with first cribellum
Several large through-holes, the lower end of first cribellum are provided with spacer bar, and the lower end of spacer bar abuts with the cone angle of dusting cover device inwall so that just
Uniform gap is provided between the outer wall of cribellum and the inwall of dusting cover device, the upper limb of first cribellum overturns to form isolation part outward, every
Abutted from portion with the inwall of dusting cover device, set accommodates oscillation ring on spacer bar.Due to there is the setting of oscillation ring, it is possible to directly shake
Dynamic just cribellum, the industrial chemicals allowed below medium size are fallen into dusting cover device, are then passed through the screening of dusting cover device again, can just be obtained
The industrial chemicals of final size, cribellum power consumption is small at the beginning of being directly vibrated using oscillation ring, and passes through and screen twice, can be with maximum possible
Ground avoids the situation of plug-hole from occurring.The present invention is used for the screening of industrial chemicals.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment
Accompanying drawing is briefly described.Obviously, described accompanying drawing is the part of the embodiment of the present invention, rather than is all implemented
Example, those skilled in the art on the premise of not paying creative work, can also obtain other designs according to these accompanying drawings
Scheme and accompanying drawing.
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Carried out below with reference to the design of embodiment and accompanying drawing to the present invention, concrete structure and caused technique effect clear
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright part of the embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to form more excellent draw bail.Each technical characteristic in the present invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
Reference picture 1, this is embodiments of the invention, specifically：
A kind of chemical industry powder sifter, includes the dusting cover device 1 of inverted cone-shaped, and dusting cover device 1 is thin-wall member, on dusting cover device 1
Several small through hole are evenly equipped with, the first cribellum 2 of inverted cone-shaped is provided with dusting cover device 1, it is big logical to be evenly equipped with several on first cribellum 2
Hole, the lower end of first cribellum 2 are provided with spacer bar 21, and the lower end of spacer bar 21 abuts with the cone angle of the inwall of dusting cover device 1 so that first cribellum
