Abstract

The utility model discloses an anti-clogging cage-bar static screen. The static screen adopts the structure that a first subsidiary screen is mounted in a frame made of metal materials in the horizontal direction; a second subsidiary screen is mounted close to the first subsidiary screen, and an angle Beta is formed between the tail part of the second subsidiary screen and the horizontal direction; a third subsidiary screen is mounted close to the second subsidiary screen, and an angle Beta' is formed between the tail part of the third subsidiary screen and the horizontal direction; L (an odd number) cage bars and L' (an even number) cage bars which are arranged on the first, the second and the third screens are connected into a whole through a first fixing beam and a second fixing beam; and the distance between two adjacent cage bar (an odd number) and cage bar (an even number) is d, and two adjacent cage bars (an odd number and an even number) are arranged in a staggered manner with an Alpha angle therebetween. The anti-clogging cage-bar static screen can screen materials in different grades without other power equipment, avoid clogging, prolong the service life of the screen frame, and save maintenance and operation costs, thereby having rather high popularization value.

Description

Anti-blocking grid section slide sieve

Technical field

The utility model relates to a kind of sieve, relates in particular to a kind of anti-blocking grid section slide sieve that is used for coke size classification, iron ore grading, dolomite mineral grading or limestone mine grading.

Background technology

The nonmetal mineral product of the coke that the coke-oven plant is produced, the iron ore of iron ore mine exploitation and exploitations such as dolomite mineral or limestone mine sieves the product of selecting size fractionated and is used for different production lines, sieves used instrument on sieve.Before the utility model, " Elastic strip screen " of ZL01213399.X arranged, its feature is that the nonmetal mineral product to different in moisture content can sieve; In addition, most of sieve is the reciprocating sieve of difformity or structure, its advantage is arranged, but it is that various types of sieves are serious through the long-term plug-hole phenomenon of using that common weak point is arranged, especially to containing the product of moisture, screening is got up hard especially, and maintenance load is big, influences the operating rate of various sieves.

Summary of the invention

The purpose of this utility model is to provide the product of a kind of effectively separate coke, iron ore, limestone mine or dolomite mineral size fractionated and improves sieve service life, reduces the anti-blocking grid section slide sieve of maintenance load.

For achieving the above object, the technical solution adopted in the utility model is: make a framework with metal material (as shaped steel), this framework constitutes the main body of described anti-blocking grid section slide sieve.In the inner one-tenth of this framework horizontal direction first fen slide sieve is installed, at its afterbody second fen slide sieve was installed from the horizontal by the β angle near first fen slide sieve, at its afterbody the 3rd fen slide sieve was installed from the horizontal by β ' angle near second fen slide sieve, divides L root odd number grid section and the L ' root even number grid section arranged on the slide sieve to fuse through first built-in beam and second built-in beam at each.The spacing of two adjacent odd number grid sections and even number grid section is d, and two adjacent odd number grid sections and even number grid section are α angle alternating expression and arrange.

Adopt a kind of anti-blocking grid section slide sieve that as above technical scheme provided compared with prior art, its advantage is:

1. be assemblied in first fen slide sieve in the framework, second fen slide sieve becomes certain angle of inclination monoblock type to install with the 3rd fen slide sieve, the material that carry out grading slips row from top to bottom and advances, do not need to each minute slide sieve impose power, provide cost savings;

2. each divides slide sieve to be arranged by many odd number grid sections and the angled alternating expression of Duo Gen even number grid section, and each odd number grid section and each even number grid section have spacing, and when the material of desired particle size classification slips when capable from top to bottom, what granularity was little falls earlier, what granularity was big falls at last, has carried out natural classification;

3. each classification hole is not a circular hole, but the cylindrical void of strip, no matter whether the material of required classification contains moisture can both pass through smoothly, does not have blockage problem;

4. the service life of whole slide sieve be prior art 5～10 times;

5. reduce maintenance load, alleviated operating personnel's labour intensity.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

In the framework 4 inner one-tenth horizontal directions of making first fen slide sieve I is installed of metal material (as shaped steel), at its afterbody second fen slide sieve II was installed from the horizontal by the β angle near first fen slide sieve I, at its afterbody the 3rd fen slide sieve III was installed from the horizontal by β ' angle near second fen slide sieve II, described β angle or β ' angle can equate or be unequal.Can also become β angle or β ' angle that the 4th fen slide sieve and the 5th fen slide sieve etc. are installed with horizontal plane at the afterbody of the 3rd fen slide sieve III according to field condition, in the application's case, only show three branch slide sieves.As Fig. 2 and shown in Figure 4, at each first minute slide sieve I, second fen slide sieve II or L (integer of L 〉=1) the root odd number grid section 1 and 1 arranged on the slide sieve III in the 3rd minute _AAnd L ' (integer of L ' 〉=1) root even number grid section 2 and 2 _AThrough first built-in beam 3 and second built-in beam 3 _AFuse.Two adjacent odd number grid sections 1 or 1 _AWith even number grid section 2 or 2 _ABetween spacing be d, perhaps two adjacent even number grid sections 2 or 2 _AWith odd number grid section 1 or 1 _ABetween spacing also be d, promptly spacing to each other equates.As shown in Figure 3, two adjacent odd number grid sections 1 are with even number grid section 2 or two adjacent odd number grid sections 1 _AWith even number grid section 2 _ABe α angle alternating expression and arrange, be i.e. even number grid section 2 or 2 _AThe α angle that is inclined upwardly also can be odd number grid section 1 or 1 _AThe form interlaced arrangement at α angle is inclined upwardly.At first built-in beam 3 and second built-in beam 3 _AOn road wheel is housed, through road wheel first minute slide sieve I, second fen slide sieve II and the 3rd fen slide sieve III are contacted with other support, a stable position is arranged.

During enforcement, 4 one-tenth certain angles of inclination of framework are installed to the operation area, make the whole heeling condition that is.Materials such as the coke of required classification, iron ore, dolomite mineral or limestone mine are transported to earlier on the 3rd fen slide sieve III, and under the gravity effect, the material of each required screening is earlier along the odd number grid section 1 and 1 on the 3rd fen slide sieve III _AAnd even number grid section 2 and 2 _ASmooth and descend, more fine-graded material is earlier from odd number grid section 1 and 1 _AWith even number grid section 2 and 2 _AThe gap fall and carried out for the first time screening, more coarsely graded material and the more fine-graded material of part that does not also fall be slippery to carry out second time to second fen slide sieve II and sieves, remaining part is slippery again to be sieved for the third time to first fen slide sieve I.Through screening several times, the grade thing of the different size of each material just can be sent into required feed bin in different screening program playback and store.In screening process, clogging can not occur, reach purpose described in the utility model.
