Description

Floating type anti-blocking sieve plate

Technical Field

The utility model relates to a shale shaker technical field especially relates to a floating anti-blocking sieve.

Background

In the current screening field, when the sieve pore is smaller than 12mm and below, and the water content is large, the material is relatively difficult to pass through the sieve due to the reasons of viscosity and the like, the screening efficiency is reduced rapidly, and the seeking of a proper anti-blocking sieve plate is vital, the current anti-blocking sieve plates comprise a cantilever bar type sieve plate, a bouncing rod type sieve plate and the like, but the effect of the current anti-blocking sieve plate is not good, the bouncing rod type sieve plate is characterized in that bars are sequentially inserted on a drilling plate, the aperture of the drilling plate is generally 0.5-1mm larger than that of the bars, when the sieve plate vibrates, the sieve plate can bounce continuously in the bouncing rod due to the 0.5-1 gap to realize anti-blocking, theoretically, the bars of the sieve plate can bounce continuously in the drilling plate, but large-scale hole blocking still occurs in the actual operation, firstly, the bars are pressed and cannot bounce, and secondly, the bounce amount is too small compared with the complex material working condition, the effect is not obvious, so the anti-blocking sieve plate which has good screening effect, does not block holes and does not block holes is urgently needed to be sought.

Disclosure of Invention

The utility model aims to overcome not enough among the prior art, provide a structural design is reasonable, not stifled hole, on-stick material prevents stifled effectual and can guarantee a floating stifled sieve of preventing of screening efficiency.

The utility model discloses a realize through following technical scheme: including fixed frame, fixed frame goes up the interval certain distance and has the floating frame through shearing spring coupling, fixed frame on be equipped with the first stick of a plurality of on the fixed drilling board, floating frame on be equipped with a plurality of second stick on the drilling board.

Preferably, the plurality of first bars and the plurality of second bars are arranged in a staggered manner.

Preferably, the first bars on the fixed frame vibrate with the box body.

Preferably, the plurality of second bars on the floating frame vibrate together with the shear springs.

Preferably, the fixed drilling plate is fixed on the fixed frame by welding.

Preferably, the floating drilling plate is welded and fixed on the floating frame.

Preferably, the fixing frame is provided with a fixing hole connected with the screen body.

The utility model discloses mainly solve below the 10mm hierarchical stifled hole problem, it is reasonable to have a structural design, not stifled hole, on-stick material prevents stifled effectual and can guarantee the advantage of screening efficiency.

Detailed Description

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, 2, 3, 4, the utility model relates to a floating anti-blocking sieve plate, including fixed frame 1, fixed frame 1 goes up the interval certain distance and is connected with floating frame 3 through shearing spring 2, fixed frame 1 on be equipped with the first stick 5 of a plurality of on the fixed drilling plate 4, floating frame 3 on be equipped with a plurality of second stick 7 on the drilling plate 6 that floats. The first bars 5 and the second bars 7 are arranged in a staggered manner. The first bars 5 on the fixed frame 1 vibrate along with the box body. The second bars 7 of the floating frame 3 vibrate together with the shear springs 2. The fixed drilling plate 4 is fixed on the fixed frame 1 by welding. The floating drilling plate 6 is fixed on the floating frame 3 by welding. The fixed frame 1 is provided with a fixed hole 8 connected with the screen body.

The fixed drilling plate 4 of the utility model is welded and fixed on the fixed frame 1, the first bar 5 is inserted in the fixed drilling plate 4, and vibrates with the fixed frame 1 during vibration; the floating drilling plate 6 is a drilling plate of the floating frame 3, the second bar 7 is inserted into the floating drilling plate 6 and fixed on the floating frame 3, and vibrates along with the floating frame 3 during vibration, and the floating frame 3 and the fixed frame 1 are connected through the shearing spring 2.

When the utility model discloses a fixed orifices 8 are fixed when vibrating along with the screen frame on the screen frame, at first fixed frame 1 is along with the screen frame constantly vibrates, and floating frame 3 only receives the periodic effort of shearing spring 2, because fixed frame 1 is different with the periodic effort that moving frame 3 receives, so can constantly periodic production relative motion between fixed frame 1 and the floating frame 3, round bar form stick has all been inserted on fixed frame 1 and the moving frame 3, so corresponding, first stick 5 and second stick 7 clearance also can constantly periodic variation around a certain fixed value (generally for required sieve mesh), because this sieve mesh constantly changes, this change is extremely little, within reasonable scope, the sieve mesh constantly slight change can destroy the tension on wet sticky material surface and to the viscidity of sieve mesh, thereby make the material pass through the sieve fast, be difficult to the viscidity hole, The hole is blocked, thereby playing a good anti-blocking effect.

The utility model discloses movable frame 3 is reciprocating motion constantly relatively fixed frame 1 to make the sieve mesh constantly change, in order to prevent stifled hole. The utility model provides a stifled hole problem when wet sticky material sieves, the hierarchical stifled hole problem of material below the main 10mm of solving.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
