Description
Technical field
The present invention relates to milling apparatus fields, and in particular to a kind of for cooperating the screening dress used when grinding host blanking
It sets.
Background technique
Powder manufacture is very important a part in modern industry, such as a variety of ores of calcium carbonate, barium sulfate are carrying out
When retrofit, it is required to that powder is made up of preprocessing, then carry out following process.The fining development of modern industry simultaneously,
Also the requirement to powder product is continuously improved.Existing power production line is processed by using grinder, cooperates conveyer belt
It is saved to transport powder product and be packed into storage room.
Large-scale grinder, which is usually matched, is arranged with continuity blanking device, so that continual attrition process is maintained, but very
The ore raw materials granular size provided when more is inconsistent, some feed particles are excessive, will lead to it and processes not in grinder
Sufficiently, processing efficiency and product quality are finally influenced, it is therefore desirable to be sieved before blanking, reject the underproof original in part
Material.Existing screening plant is usually rotary screen or shaking screen, is that passing through for particle is screened using the size of sieve pore.But
This screening plant has certain problems: first is that efficiency of screen out is low when the face of screening is lesser, being easy to happen blocking etc.
Problem influences raw material addition；Second is that sieve diameter is fixed, the particle demand of raw material be added can not be adjusted in time, is not adapted to
Modern intelligent grinder.
Summary of the invention
For the deficiency in the presence of the prior art, the present invention provides a kind of grinding host blanking screening mechanism, to
Solve efficiency of screen out present in screening plant in existing grinder it is low, be easy blocking and sieve pore fix, sieve can not be adjusted
The problem of selecting demand.
To achieve the above object, present invention employs the following technical solutions:
A kind of grinding host blanking screening mechanism, including the feed pipe, screening machine and discharge nozzle set gradually from top to bottom,
Wherein screening machine upper and lower ends opening is connect with feed pipe, discharge nozzle, and screening machine side is additionally provided with the feed back pipe tilted down；Also
Including the elevating conveyor being vertically arranged, described elevating conveyor one end is connect with feed back pipe, and the other end is connected with Material disintegrator, institute
The outlet for stating Material disintegrator is connected to the side of feed pipe；
The screening machine includes the impeller of cylindrical housing and coaxial arrangement inside the housing, and the impeller is located at feed pipe
Perpendicular to feed pipe, the lateral surface of the shell is respectively equipped with three openings and feed pipe, goes out the rotation axis of underface and impeller
Expects pipe and feed back pipe connect one by one, the diameter of the impeller matched with the diameter of shell can covering shell rounded face and from
By rotating.
Compared with the prior art, the invention has the following beneficial effects:
1, the present invention is sieved by the impeller being arranged perpendicular to feed pipe, and impeller is flat there is no screening out where sieve pore
The problem of face, therefore in the case where the face of screening is small, screening efficiency is impacted less, can greatly improve screening efficiency, also not
The case where will cause blocking reduces maintenance time and cost；
2, the velocity of rotation of impeller is adjustable in the present invention, compared to the sieve plate and sieve of fixed sieve diameter, Ke Yigeng
Add granular size sieved required for free adjustment, to cooperate different grinder configurations and different revolving speeds to carry out
It is most reasonable to arrange, obtain the powder product of better quality；
3, impeller side of the invention is additionally provided with feed back pipe, so that the unqualified raw material sifted out is discharged, then passes through promotion
Conveyer member, which is dredged, to be re-worked in Material disintegrator and is back in feed pipe, can be handled unqualified raw material with automatic cycle, be improved
Raw material processing efficiency.

Specific embodiment
The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
Embodiment:
As shown in Figure 1-3, the invention proposes a kind of grinding host blanking screening mechanisms, including set gradually from top to bottom
Feed pipe 1, screening machine 2 and discharge nozzle 3, wherein 2 upper and lower ends of screening machine opening connect with feed pipe 1, discharge nozzle 3, this reality
It applies feed pipe 1 and discharge nozzle 3 in example to be collinearly arranged, so that the upper and lower ends opening of screening machine 2 is oppositely arranged, raw material can be along perpendicular
Histogram does not fall off and is skewed off to elsewhere to whereabouts.
2 side of screening machine is additionally provided with the feed back pipe 4 tilted down in the present invention, in preferred scheme, feed back pipe 4 and discharging
The angle of pipe 3 is 30~60 °, and the present embodiment is 45 °, is returned for that will screen underproof raw material.The invention also includes vertical
The elevating conveyor 5 of setting, described 5 one end of elevating conveyor are connect with feed back pipe 4, and the other end is connected with Material disintegrator 6, described broken
The outlet of material machine 6 is connected to the side of feed pipe 1；Therefore the unqualified raw material sifted out can be discharged, then by promoting conveying
It dredges for 5 yuan of machine and re-works and be back in Material disintegrator 6 in feed pipe 1, unqualified raw material can be handled with automatic cycle, improved former
Expect processing efficiency.
In the present embodiment further embodiment, the screening machine 2 includes cylindrical housing 21 and is co-axially located at shell 21
Internal impeller 22, impeller 22 includes 6~10 blades 221, and the blade 221 is radially uniformly distributed, this implementation
8 blades 221 are used in example.The impeller 22 is located at immediately below feed pipe 1 and the rotation axis of impeller 22 is perpendicular to feed pipe
1, so that the raw material fallen from feed pipe 1 directly falls in 22 surface of impeller, so that the impeller 22 being rotated drives, need to illustrate
, 22 rotation direction of impeller is along the direction of feed pipe 1, discharge nozzle 3, feed back pipe 4 in the present embodiment；The biggish material of particle
Inertia is larger during rotation, thus be easier in 22 rotation process of impeller pass through discharge nozzle 3 enter feed back pipe 4, from
And play sieving actoion.The lateral surface of shell 21 is respectively equipped with three openings and connects one by one with feed pipe 1, discharge nozzle 3 and feed back pipe 4
It connects, the diameter of the impeller 22 is matched with the diameter of shell 21 21 rounded face of covering shell and to be freely rotated.
In preferred scheme, 221 surface of blade is waveform, choppiness the radially extending along impeller 22, and wave
The length of single arc is matched with the average particle size of raw material be added in shape wave.Particulate materials are preferably adhered to
On 221 surface of blade, feed inlet and outlet will not be directly slid because of gravity, preferably guarantees screening effect.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
