Abstract
The utility model belongs to the technical field of screening machinery and particularly relates to a high aperture ratio polyurethane sieve plate which comprises a sieve frame, a sieve surface, and sieve slits. The sieve frame is disposed below the sieve surface and is connected with the same. The high aperture ratio polyurethane sieve plate is characterized in that the sieve slits are continuously distributed on the whole sieve surface, the sieve frame is formed by intersecting and connecting transverse boards and vertical boards, the transverse boards are higher than the vertical boards, the transverse boards are connected with the sieve surface, the upper portion of each sieve slit is wider than the lower portion, and the sieve frame is clamped to the sieve surface through grooves and lugs matching with each other. The high aperture ratio polyurethane sieve plate has the advantages aperture area and aperture ratio are increased, operating efficiency is increased, bottom space of the sieve surface is large, the problem that materials are jammed easily when passing the sieve slits is solved, passage capacity of the sieve plate is increased, and the sieve plate is convenient to dismount. The high aperture ratio polyurethane sieve plate is high in operating efficiency, fine in passage capacity, simple in structure and easy to implement.
Description
Technical field
The utility model belongs to the sieving machine technical field, relates in particular to a kind of high opening rate polyurethane sieve plate.
Background technology
The sieve plate that domestic vibratory sieve or drum sieve are used mostly is stainless steel strip net or common metal net greatly, not only wear no resistance, corrosion-resistant, and weight is big, life-span is short, in order to improve the performance of sieve plate, now a lot of sieve plates all use polyurethane to make, and polyurethane sieve plate is a kind of high polymer elastic sieve plate, and it has excellent wear-resisting, oil resistant, hydrolysis, ageing resistace.This sieve plate can not only alleviate weight of equipment significantly, reduces equipment cost, prolongs equipment life, and reduces noise, is widely used in industries such as metallurgy, coal, mine, coke, chemical industry.The full-polyurethane sieve plate of present prior art, generally comprise screen frame, compass screen surface, sieve seam, dividing plate, sieve plate generally passes through bolted, dismounting trouble, and bolt loses easily, and be provided with barrier in the middle of when compass screen surface cracks, anyhow screen frame is all very big with compass screen surface interconnection and joint face, so just taken the very big area of compass screen surface, percent opening is descended significantly, thereby operating efficiency is also descended significantly.Be exactly that barrier and screen frame in the middle of cracking on the compass screen surface all makes the performance of passing through of sieve plate descend with the cross-coupled joint face of compass screen surface in addition, material by the time be stuck in problem such as centre easily, so just have influence on precision and the quality of screening.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of high opening rate polyurethane sieve plate, comprise screen frame, compass screen surface, the sieve seam, described screen frame is arranged under the described compass screen surface and with described compass screen surface and is connected, it is characterized in that on the described compass screen surface of described sieve seam continuous distributed, and be full of the sieve seam on the described compass screen surface, described screen frame is formed by transverse slat and the mutual interconnection of riser, the height of described transverse slat is greater than the height of described riser, and described transverse slat is connected with described compass screen surface, described sieve is sewed on the width of portion greater than the width of bottom, groove and the projection clamping by cooperatively interacting of described screen frame and described compass screen surface.
The shape of cross section of described sieve seam is trapezoidal.
The material of described sieve seam is polyurethane.
Described riser interts in described transverse slat.
Described sieve seam is vertical bar seam.
The beneficial effects of the utility model are: cancelled the setting of dividing plate, sieve is sewn on the compass screen surface can continuous distributed, perforated area and percent opening have been increased, improved operating efficiency, by facts have proved that high opening rate polyurethane sieve plate of the present utility model doubles than the polyurethane sieve plate of prior art, operating efficiency also is doubled, screen frame is formed by transverse slat and the mutual interconnection of riser, and riser does not connect compass screen surface, and such design just makes the space of compass screen surface bottom strengthen, easy jammed problem when having solved material by the sieve seam, improved the performance of passing through of sieve plate, be connected with projection by groove between sieve plate and the compass screen surface, easy accessibility saves time.The utility model high efficiency, good, simple in structure by performance is easy to realize.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model sieve seam.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation.
Among the figure, 1, screen frame, 2, compass screen surface, 3, the sieve seam, 4, transverse slat, 5, riser, 6, groove, 7, projection.
As Fig. 1, shown in Figure 2, the high opening rate polyurethane sieve plate that the utility model provides, comprise screen frame 1, compass screen surface 2, sieve seam 3, screen frame 1 is arranged on compass screen surface 2 times and is connected with compass screen surface 2, on the sieve seam 3 continuous distributed compass screen surfaces 2, sieve seam 3 is vertical bar seam, and be full of sieve seam 3 on the compass screen surface 2, screen frame 1 is formed by transverse slat 4 and riser 5 mutual interconnections, and the height of transverse slat 4 is greater than the height of riser 5, and transverse slat 4 is connected with compass screen surface 2, riser 5 interts in transverse slat 4, and the width on sieve seam 3 tops is greater than the width of bottom, and the shape of cross section of sieve seam 3 is trapezoidal, the material of sieve seam 3 is polyurethane, screen frame 1 and the groove 6 and projection 7 clampings of compass screen surface 2 by cooperatively interacting.
Make use-case: during use, by groove 6 and projection 7 sieve plate is installed earlier, then sieve plate of the present utility model is installed on the corresponding machine, material is by sieve seam 3, is sized out respectively according to the difference of material size.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should belong within the patent covering scope of the present utility model.
