Abstract
The utility model discloses a double-roller sheet crusher, relates to a crusher and solves the problem that the sheet teeth of the existing crusher are easily broken and inconvenient to repair. In the crusher, the structures of a movable roller and a fixed roller of the existing crusher are improved; multiple upper sheet tooth groups of the movable roller and multiple lower sheet tooth groups of the fixed roller are formed by fixing four 90-degree sector cylindrical tooth plate components respectively; and each sector cylindrical tooth plate component comprises a blade support and multiple sheet tooth groups integrally cast with the blade support, and is fixed on a roller shaft by a bolt. Since the sheet tooth groups and the blade supports of the movable roller and the fixed roller are assembled by integrally pouring 1/4 round sector cylinders and fixed on the fixing bolt slots and roller shafts by bolts, the sheet teeth are easy to replace; and moreover, since the side edge of the sheet tooth is made into an arc shape, the sheet tooth is not easily broken, and the service life of the crusher is prolonged.
Description
Technical field
The utility model relates to a kind of disintegrating machine, refers in particular to a kind of pair of roller chip disintegrating machine.
Background technology
Generally be furnished with a disintegrating machine in the pitch coke calciner plant in the smelter, be used for broken big lump coke.Its operation principle is: two round rollers that have a plurality of roller teeth respectively rotate with relative direction, make the bulk materials (coke) that falls between the disintegrating machine two roller roller teeth, under two roller relative direction turning efforts, are squeezed and are broken into the material of granularity.
Referring to Fig. 1, the primary structure of disintegrating machine is following:
Cycloid speed reducer 11 is power parts, is used to transmit moment, makes following stationary roll turn round;
Stationary roll 13 (can not adjust) is the rotation roller of band array (present embodiment is 6 groups) last slice tooth group 25;
The rotation roller of movable roll 14 (can adjust and stationary roll 13 between distance) is band quantity arrays (6 group) time sheet tooth group 25' identical with last slice tooth group 25, its through and stationary roll between mutual extrusion, broken coke.Following sheet tooth group 25' intersects with each sheet tooth group of last slice tooth group 25 and cooperates installation;
Gear-box 16 is connected with stationary roll 13 and movable roll 14 respectively, regulates the position of movable roll 14 and drives movable roll 14 rotations.
Existing disintegrating machine stationary roll and movable roll structure are following:
Shown in Fig. 2-3, Fig. 2 is existing disintegrating machine stationary roll and movable roll structure chart, is second figure of stationary roll (symmetry up and down), following first figure of movable roll of being (symmetry up and down) above; Fig. 3 is movable roll and stationary roll sheet tooth group structure diagram in the existing disintegrating machine.Last slice tooth group 25 in stationary roll 13 and the movable roll 14 is identical with following sheet tooth group 25' structure; Six groups of sheet tooth groups are all arranged on movable roll in the existing equipment and the stationary roll; And intersection cooperates installation; Each sheet tooth group is a single component, and adjacent two tooth groups are separated with spacer ring, guarantee the spacing of adjacent two tooth groups.Each sheet tooth group and spacer ring are installed in respectively separately on the axle, and with 8 fastening (see figure 2)s of screw rod; Keyway 21 is installed shaft coupling 12 among Fig. 2; Axle 22 is connected with bearing 23, fixes with key; Last slice tooth group 25 is enclosed within on the axle 22, and be through with screw rod 24 and install in the screw hole 31, and with locking nut that screw rod 24 is fastening; Label 32 is an axis hole among Fig. 3.
Because the user has requirement to product quality, require the granularity control index of broken back coke following: the following granularity of 30mm about 4.8%; Granularity about 22.3% between the 30-60mm; Granularity about 72.9% between the 60-80mm.Therefore on the circumference of each gear piece group of disintegrating machine, the alternate sheet toothing of length (lengthy motion picture tooth 33 shown in Figure 3 and short-movie tooth 34) is set, and the distance of length sheet tooth is had dimensional requirement, be intended to guarantee the granularity after the coke fragmentation.
The said structure disintegrating machine is after long-term the use, and wherein local sheet tooth fracture shortens, and most of sheet odontotripsis has a strong impact on fragmentation quality.The major defect of its existence is: it is bigger 1, to change sheet tooth group difficulty, because disintegrating machine is through after using, corrosion takes place the work under long-term wet environment of screw rod and locking nut.If concentrated wear of sheet tooth and fracture occur, need to remove when changing sheet tooth group, the basic employing destroyed screw rod and locking nut, and burst is removed and is changed then; When sheet tooth group and spacer ring corrosion occurring, when local replacing sheet tooth group and spacer ring, fitted position is difficult to guarantee that must a whole set of sheet tooth group and spacer ring, screw rod and locking nut together be upgraded, expense has high input.2, the unreasonable structure of sheet flank limit blade is prone to wearing and tearing.The blade that existing tooth contacts with coke is rectilinear form (shown in Figure 3), when blade with after coke contacts, when coke is squeezed, can produce slip, long-term and blade friction, the blade wearing and tearing are bigger, even rupture, and shortened the service life of blade.Coke slides in extruded space again, can cause windrow or the flash of moment, and influence is the linking of operation up and down, needs artificial clear material, has unsafe factor.3, the top structure of sheet teeth cutter blade unreasonable (top is a rectilinear form) when accepting coke, is difficult to pin coke, and coke also relative slip can take place, and influences sheet tooth service life.
