Description

A kind of drum sieve

Technical field

The utility model relates to a kind of drum sieve, belongs to screening plant.

Background technology

Chinese patent ZL200520036705.5 discloses a kind of " drum sieve ", this drum sieve comprises feed arrangement and places the sifting barrel that rotates on the support roller, sifting barrel is made up of inside and outside two-layer at least cylindrical shell, the number of plies is uncertain by the granularity progression that material need sieve, and each layer screen drum end is provided with corresponding discharging opening; The perisporium of each cylindrical shell of internal layer is provided with sieve aperture, sieve aperture on the cylindrical shell is through diminishing step by step from the internal layer to the skin, the outlet of feeding device is communicated with the inlet of the innermost layer of sifting barrel, the discharging opening of each layer of sifting barrel is isolated mutually, sifting barrel is positioned on the support roller of rotation and by support roller and drives revolution, material skid in screen drum advances, and is screened into some particle size ranges and send mouth from discharging opening separately respectively.

The sieve plate of present widely used drum sieve all adopts steel construction, and the drum sieve sieve plate of this metal structure is coarse, heavy, not wear-resisting, but also also inconvenience is installed in stifled ore deposit, and the life-span is short, has a strong impact on production efficiency, has increased working strength of workers.

Summary of the invention

The purpose of this utility model aims to provide a kind of wear-resisting, light, energy-conserving and environment-protective, screening is even and efficient is high drum sieve.

To achieve these goals, drum sieve of the present utility model is made up of steel outrigger, sieve plate and deflector, in the described steel outrigger sieve plate is set, locking strip and installing plate are set between sieve plate, between the sieve aperture of sieve plate flexible back bone is set, fixedly connected with the steel outrigger in the two ends of flexible back bone, the sieve plate two ends are provided with backplate, on the sieve plate inner surface spiral type flow guide plates is set; Described locking strip, setting is matrix, upper end two arranged outside projectioies, it is circular-arc that projection is, perhaps rectangular triangular form, the corresponding matrix that is of described installing plate with locking strip, two inboards, upper end are provided with projection, it is circular-arc that projection is, perhaps rectangular triangular form, and fixedly connected with the steel outrigger in the installing plate bottom.

Drum sieve of the present utility model compared with prior art has following excellent effect.

Sieve plate adopts abrasive rubber to manufacture, improved the service life of sieve plate, the light energy consumption that reduces sieve plate work of rubber, being evenly distributed of sieve aperture effectively sieved material, embeds locking strip between sieve plate, make sieve plate stable and unshift, locking strip upper end and the installing plate corresponding embedding mutually in upper end, fixedlying connected with the steel outrigger in the installing plate bottom, has guaranteed the stability of sieve plate; Flexible back bone between sieve aperture has played the effect of reinforcement, makes the aperture of elasticity sieve aperture stable, has overcome stifled sieve phenomenon, has guaranteed the quality and the efficient of material screening; The spiral setting of deflector makes material spiral mobile along same direction, has guaranteed that material screening is even, has improved material screening efficient.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Drum sieve shown in Figure 1 is by a steel frame 1, sieve plate 2 and deflector 3 are formed, steel outrigger 1 is made cylindrical, sieve plate 2 is mated formation on the inwall of steel outrigger 1 cylindrical drum, backplate 4 is arranged on the two ends of steel outrigger 1 cylindrical drum, to 2 fixations of sieve plate, sieve plate is provided with spiral type flow guide plates 3 on 2 surfaces, and fixedly connected.

Sieve plate 2 shown in Figure 2 is made up of sieve aperture 10 and flexible back bone 5, and sieve aperture 10 evenly is arranged on the sieve plate 2 by the material grade, and flexible back bone 5 adopts polyamide fabric or soft steel wire to be arranged between the sieve aperture 10, fixedlys connected with steel outrigger 1 in flexible back bone 5 two ends.

Deflector shown in Figure 33 is screw type to be fixedly connected on the surface of sieve plate 2, to guarantee the flow direction of material screening.

Locking strip 6 and installing plate 7 shown in Figure 4 all are set to matrix, the two arranged outside outside, the upper end projection 8 of locking strip 6, and two inboards, upper end of installing plate 7 are provided with inner bulge 9, locking strip 6 and installing plate 7 embed between the sieve plate 2 accordingly, to 2 fixations of sieve plate, easy accessibility, and safety.

Fig. 5 and locking strip 6 shown in Figure 7 are matrix, and locking strip shown in Figure 56 upper ends two arranged outside are circular-arc outside projection 8, the rectangular triangular shape of locking strip shown in Figure 76 upper ends two arranged outside outside projection 8.

Locking strip 6 shown in Figure 6 is a rectangle, and upper end two arranged outside are circular-arc outside projection 8.
