Abstract
The utility model relates to a screening machine for sandstone. The utility model comprises an inner roller, an outer roller, a roller supporting wheel, a bearing seat, a loading hopper and a bracket, wherein, the rollers are driven by a motor and a speed reducer to rotate; the rollers and the horizontal plane of the bracket are slantways arranged axially; the surface of the inner roller is welded into a wide meshed screen by steel bars; the surface of the outer roller is provided with a fine meshed screen and a middle meshed screen. In order to ensure that the rollers are rotated in a vibrational state, the inner part of the bearing seat is provided with a self-aligning bearing with a spherical surface, and a radial stop bearing. The utility model can be used for continuously producing the sandstone with various specifications in a large scale.
Description
The utility model relates to the device that varigrained solid is screened separation, particularly a kind of aggregate screening machine.
Building needs sandstone, according to the varigrained sandstone of purposes different needs, the granularity of existing sandstone factory or sandstone raw sand that application units get is generally widely different, therefore be badly in need of a kind of aggregate screening machine, it both can screen the sandstone of different size, and it is simple and reasonable, the efficient height, can satisfy the needs of large-scale production sandstone, Chinese patent (CN2073777U) once disclosed a kind of self-propelled sand sieving machine, and it can produce the sandstone of three kinds of specifications, and take up an area of little, movable operation, but weak point is this machine complex structure, efficient is low, does not satisfy the needs of mass automatic production sandstone.
The purpose of this utility model provides a kind of simple and reasonable, cost is low, efficient is high aggregate screening machine.
The purpose of this utility model is achieved in that the aggregate screening machine comprises motor 12, reductor 10, bearing block 8, interior cylinder 3, outer cylinder 2, loading hopper 1, screen cloth 4,5,6, cylinder support wheel 16, sandstone discharging opening 13,14,15 and support 17.Raw sand is cylinder 3 in loading hopper 1 enters at first.The welding of interior cylinder wide-meshed screen 6 usefulness reinforcing bars, rubble is discharged through the interior cylinder other end, in, fine sand is by the interior cylinder outer drum inner surface screen cloth that bleeds.Outer cylinder is risen by feed end and arranges fine screen mesh 4 and middle screen cloth 5 respectively, is risen to the outer cylinder surface of cylinder low side by middle screen cloth and does not arrange screen cloth, also can arrange the screen cloth of different fineness as required.When cylinder rotated with certain speed, fine sand and medium sand were spilt by sandstone discharging opening 15,14 respectively.One end of whole cylinder is supported by two cylinder support wheels 16, the other end is supported by bearing block 8, spherical self-aligning bearing 18 and axial thrust bearing 19 are arranged in bearing block 8, be used for back-up roller, and can prevent to damage when cylinder causes power-transmitting part when off-centre is rotated, guarantee cylinder normal rotation under vibrational state.Drum shaft is 5-10 ° of angle to the horizontal plane with support, and sandstone is discharged smoothly from discharging opening in the cylinder that rotates.
The utility model has the advantages that: simple and reasonable, cheap, operating efficiency is high, can screen the sandstone of different size by the screen cloth of changing different size, therefore, this device can be suitable for large-scale continuous production as corollary equipment.
In conjunction with the accompanying drawings the utility model is done with explanation:
Fig. 1 is the structure chart of aggregate screening machine.
Fig. 2 is the bearing block cutaway view.
Wherein: 1, loading hopper, 2, outer cylinder, 3, interior cylinder, 4, outer cylinder fine screen mesh, 5, screen cloth in the outer cylinder, 6, interior cylinder wide-meshed screen, 7, ring flange, 8, bearing block, 9 is cross to wheel, 10, reductor, 11, the reductor belt pulley, 12, motor, 13, grit discharging opening, 14, middle sandstone discharging opening, 15, grail discharging opening, 16, the cylinder support wheel, 17, support, 18, spherical self-aligning bearing, 19, axial thrust bearing.
During by dress aggregate screening machine, cylinder axially horizontal by 5-10 ° of angle.When the aggregate screening machine is worked, with transmitting band sandstone is delivered to loading hopper, sandstone at first enters interior cylinder, the cylinder velocity of rotation is 15 rev/mins, interior cylinder wide-meshed screen is welded into the graticule mesh of 45 * 45mm with reinforcing bar, and in order to screen out grit, outer cylinder is arranged the fine screen mesh of 5 * 5mm and the middle screen cloth of 20 * 20mm respectively, so just can filter out the sandstone of granularity for＜5mm, 5-20mm reaches〉20mm.Also can change the sandstone that screen cloth is produced other granularity according to actual needs.
Claims (2)
1, a kind of aggregate screening machine, comprise cylinder, screen cloth, the cylinder support wheel, motor, reductor, loading hopper and support are formed, it is characterized in that cylinder and support level face are is in tilted layout, and the upper end of cylinder is supported by cylinder support wheel 16, and the cylinder lower end that connects with reductor 10 is by bearing block 8 supports; Cylinder is made up of with interior cylinder 3 the outer cylinder 2 with same axis, cylinder wide-meshed screen 6 in interior cylinder surface is welded into reinforcing bar, corresponding fine screen mesh 4 and the middle screen cloth 5 installed respectively with discharging opening of outer cylinder surface.
2,, it is characterized in that in bearing block 8, being equipped with spherical self-aligning bearing 18 and axial thrust bearing 19 according to the described aggregate screening machine of claim 1.
