Abstract
The invention discloses a material cake grinding and classifying screen which comprises an outer shell. The top and the bottom of the outer shell are respectively provided with a feed inlet and a coarse material outlet. Two groups of matched clapboards are arranged in the outer shell. Two fine material cavities are respectively formed outside the two groups of clapboards. The clapboards are respectively formed by connecting guide plates with sieve plates end to end and are respectively of a multilayer bent shape. A bent channel communicated between the feed inlet and the coarse material outlet is formed between the two groups of clapboards. Fine material outlets are arranged at the positions at the bottom of the outer shell, which correspond to the fine material cavities. The sieve plates are arranged at one or more positions on each clapboard, which are opposite to the flowing direction of materials in the bent channel. The material cake grinding and classifying screen is used for grinding and sieving materials ground by a roll squeezer and compressed into material cakes to create conditions for a subsequent treatment process, can be widely applied in powder preparation places in the industries such as building materials, chemical industry, metallurgy, mines and the like, and is particularly suitable for a pregrinding or final grinding system which uses the roll squeezer as a raw meal mill and a cement grinding mill in the cement industry.
Description
Technical field:
The present invention relates generally to a kind of material cake crushing and screening equipment, relates in particular to the broken classifying screen of a kind of material cake.
Background technology:
Prior art is scattering and grading machine and V-type powder concentrator.Can consult the periodical that code of post issue is 2-325 " cement "; 1996 the 9th phases the 26th page " application of scattering and grading machine in extruding combination grinding technology " and 2008 the 2nd phases the 39th page " application of V-type powder concentrator in extruding precrushing closed-circuit system ".
Existing scattering and grading machine is equipped with two motors, and occupation of land is big, vibrations are big, the investment height.Existing " V-type powder concentrator " is to come sorting through swiftly flowing air, and the sorting particle size adjustment is convenient, but system must be equipped with powerful blower fan and cleaner, and floor space is big, investment height, system complex, power consumption height.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, provides a kind of material cake broken classifying screen, and it does not promptly need power source; Powerful attached blower fan of big air quantity and cleaner need be provided again; Small investment is taken up an area of for a short time, and power consumption is low; But can break up and classification, for subsequent treatment process creates conditions the material cake that roll squeezer comes out.
The present invention realizes through following technical scheme:
The broken classifying screen of a kind of material cake; It is characterized in that: include shell body; The top of shell body and bottom are respectively equipped with charging aperture and coarse fodder outlet; Be provided with the dividing plate of two groups of couplings in the said shell body, the outside of said two groups of dividing plates is formed with the fines chamber respectively, and said dividing plate is respectively to be connected from beginning to end by stock guide and sieve plate to be multilayer bending shape; Be formed with the bent passage that is communicated between charging aperture and the coarse fodder outlet between said two groups of dividing plates, the position in corresponding fines chamber, shell body bottom is provided with the fines outlet; On the said dividing plate with bent passage in the relative one or more positions of flow direction of material be made as sieve plate.
The broken classifying screen of described a kind of material cake is characterized in that: said dividing plate plate is respectively that and head and the tail spaced apart with sieve plate are connected and are multilayer and bend shape by stock guide, and wherein, position adjacent with charging aperture on the dividing plate is made as sieve plate.
The broken classifying screen of described a kind of material cake, it is characterized in that: said sieve plate is the steel plate of perforate or fluting.
The broken classifying screen of described a kind of material cake is characterized in that: said sieve plate is to be become by rectangular steel splicing or weaving surface.
After the material cake was through charging aperture feeding the present invention, the material cake from top to bottom through the bent passage of these complications, received the bump repeatedly of sieve plate and fragmentation is sized simultaneously under the effect of gravity.In the bottom of passage, the thick material that does not pass sieve plate is pooled to the meal discharging opening, discharges broken classifying screen as defective work, returns roll squeezer and pushes again.And the thin material that passes sieve plate is regional away from sieve plate by the stock guide guiding, is collected by shell body, discharges broken classifying screen from the fine powder discharging opening then, gives the next stage treatment process as certified products.
The specific embodiment
The present invention can implement through following steps:
As the sieve plate of important spare part of the present invention, both can use the steel plate of perforate, also can use the steel plate of fluting, perhaps with steel wire or steel bar establishment, can also use the bar steel splicing of various cross sectional shapes, the crushing and screening face needs wear-resistant.
Advantage of the present invention is:
The present invention is used for the material that is compacted into the material cake after crowded broken by roll squeezer is again carried out fragmentation and screening; Thereby for subsequent treatment process creates conditions; The powder preparing occasion that can be widely used in industries such as building materials, chemical industry, metallurgy, mine is particularly useful for selecting for use in the system of roll squeezer as the precomminution of the raw mill of cement industry and cement grinding mill or whole grinding.
The specific embodiment:
Referring to accompanying drawing.
The broken classifying screen of a kind of material cake; Include shell body 4; The top of shell body 4 and bottom are respectively equipped with charging aperture 1 and coarse fodder outlet 6; Be provided with the dividing plates of two groups of couplings in the said shell body 4, the outside of said two groups of dividing plates is formed with fines chamber 7 respectively, and said dividing plate is respectively that spaced apart and head and the tail are connected and are multilayer and bend shape by stock guide 3 and sieve plate 2; Be formed with the bent passage that is communicated between charging aperture 1 and the coarse fodder outlet 6 between said two groups of dividing plates, the position in corresponding fines chamber, shell body 4 bottoms 7 is provided with fines outlet 5; Be sieve plate 2 with charging aperture 1 adjacent position on the dividing plate.Sieve plate 2 both can have been used the steel plate of perforate, also can use the steel plate of fluting, perhaps with steel wire or steel bar establishment, can also use the bar steel splicing of various cross sectional shapes, and the crushing and screening face needs wear-resistant.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
