Small, material movement in screen cloth is slower, and less efficient, angle of inclination is excessive, and material is mobile very fast in screen cloth, and screening is not filled
Point.
In a preferred embodiment, support body 100 is 2~4 layers, such as 2 layers, 3 layers or 4 layers.
When support body is two layers, cylinder screen 200 is two, and when support body is three layers, cylinder screen 200 is three, when
When support body is four layers, cylinder screen 200 is four.Cylinder screen 200 is excessive, and space-consuming is excessive, and cylinder screen 200 is very few,
It is unfavorable for improving production efficiency.
In a preferred embodiment, the barrel lenght of cylinder screen 200 is 5~10m, for example, 5m, 6m, 7m, 8m,
9m or 10m.
The barrel lenght of cylinder screen 200 can be adjusted according to practical condition, and barrel lenght is too short, screening effect
Fruit is bad, and barrel lenght is long, and it is unstable to easily cause cylinder during rotation.
In a preferred embodiment, the barrel diameter of cylinder screen 200 is 0.7~1.5m, such as 0.7m,
0.8m, 0.9m, 1m, 1.2m or 1.5m.
Effectively the material of different-grain diameter can be sieved using the cylinder screen 200 of specific barrel diameter scope,
Barrel diameter is too small, and the material finite capacity of splendid attire, barrel diameter is excessive, and screening effect is bad.Barrel diameter can be according to production
Amount, the difference of screening amount are adjusted.
In a preferred embodiment, as shown in figure 5, multi-layer cylinder sieve also includes charging gear；Charging gear goes out
Tripper 400 is set below mouthful, and tripper 400 is connected by feed pipe with each charging aperture 230.
Preferably, charging gear is oscillating feeder.
It can be set and divided below charging gear outlet simultaneously toward feeding in multiple cylinder screens 200 by charging gear
Glassware 400 so that the material of charging gear output can be equably sent into different cylinder screens 200.Only needed during use to
Fed intake in charging gear, material can be simultaneously evenly into being sieved in each cylinder screen 200, can be to large batch of
Material is sieved simultaneously, improves production efficiency.
Preferably, the outlet of tripper 400 is provided with slide valve.
By the Truncation of slide valve when some cylinder screen 200 breaks down, can be made by closing slide valve
Material does not enter in the cylinder screen 200, convenient that the cylinder screen 200 is independently serviced.
According to other side of the present utility model, there is provided a kind of screening system, wherein：Fig. 5 is the utility model one
The structural representation of the screening system of kind embodiment.
As shown in figure 5, screening system comprises at least one group of above-mentioned multi-layer cylinder sieve, screening system can also be by multigroup
The multi-layer cylinder sieve stated forms side by side, and so multigroup drum sieve that is chopped into can work simultaneously, further to improve production efficiency.Should
Screening system has sieves same advantage with above-mentioned multi-layer cylinder.

Be advantageous to improve operating efficiency with conveyer belt 500, save recruitment, reduce workload.
By taking the production of ceramsite propping agent as an example, the work of multi-layer cylinder sieve and screening system of the present utility model is illustrated
Process：
Multi-layer cylinder sieve is arranged to three layers, and solid is put, and ceramsite propping agent material, feeding machine are added into feeding machine 300
300 equably enter cylinder screen 200 by tripper 400 to feeding at the charging aperture 230 of three cylinder screens 200, material
Afterwards, under the rotary action of cylinder screen 200, material skid in cylinder screen 200 advances, and is sieved by the first cylinder screen 210
The small mother bulb material gone out is fallen on the first discharging swash plate 251, is slid to the first discharging pipeline 261, by the second cylinder screen 220
The big mother bulb material sifted out is fallen on the second discharging swash plate 252, is slid to the second discharging pipeline 262, not by the first cylinder
The ceramsite propping agent (more than required particle diameter) that the cylinder screen 220 of screen cloth 210 and second sifts out finally flows from the discharging opening 240 of afterbody
Go out.After the first discharging pipeline 261 being finally pooled in each cylinder screen 200 by the small mother bulb that the first cylinder screen 210 sifts out
Into elevator, small mother bulb feed bin is promoted to by elevator, sifted out in each cylinder screen 200 by the second cylinder screen 220
Big mother bulb be finally pooled to the second discharging pipeline 262 after enter elevator, big mother bulb feed bin is promoted to by elevator, each
The waste material of the afterbody discharging opening 240 of cylinder screen 200 outflow is flow on conveyer belt 500 by deflector chute 241, defeated by conveyer belt 500
Waste disposal equipment is sent to be handled.
When a whole set of multi-layer cylinder riddler makees, it is only necessary to people's operation, both reduce labour, improve production again
Efficiency, the efficiency of this outer screening also improve, particularly the length of screen drum, can effectively screen out large and small two kinds of mother bulbs, right
The production efficiency of next process also functions to raising effect, and big mother bulb also shortens in the time of balling-up disc molding, small mother bulb energy
It is enough separately formed, improve yield rate.A whole set of multi-layer cylinder sieve floor space is small, and operating efficiency is high, and automaticity is high, and screen cloth is more
Change easy to maintenance, save manpower.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
