Description
Technical field
The utility model relates to the technical field of screening plant, especially one and there are two grades of screening plants
Block-resistant type rotary screen.
Technical background
Rotary screen is mainly and solid material carries out the equipment that screening separates, and enters the material of rotary screen along with sieve
The rotation of cylinder and overturn and roll, qualified material discharging opening bottom screen drum is discharged, underproof
Material is discharged through the discharge gate of screen drum afterbody.In building trade, rotary screen be a requisite equipment it
One.Dry sand can be screened by operator, and the dry sand screened is typically between 0～5mm, the most not
It can be screened further, in building trade, it is often necessary to the dry sand of various different ratio.After
Carry out scientific research personnel rotary screen is improved further, rotary screen arranges different size of sieve aperture and enters
Row sieves further, but during screening, usually there will be the dry sand of various component, screening
Ratio is the most uneven, and the powder ash particle in dry sand is 0～0.075mm, and content the most usually can affect entirety
The quality of dry sand.
During traditional rotary screen operation, the problem that usually there will be is exactly that sieve aperture blocked by material
Problem, it is common that by the way of people are to be tapped by iron hammer, clear up sieve aperture, so cleaning mistake

Detailed description of the invention
The block-resistant type rotary screen with two grades of screening plants as shown in Figures 1 to 3, mainly by frame 1, cylinder
Sieve 2, electric rotating machine 3, rotary shaft 4, outer housing 5, be arranged on outer housing 5 one end charging aperture 6, be arranged on outside
Cover the waste material discharging opening 7 of 5 other ends, anti-block apparatus 8 and be positioned at two grades of screening plant compositions of outer housing 5 lower end；
Rotary screen 2 is arranged in frame 1 horizontal by 5 °～10 °；Such design can facilitate by air bubble
The blocking material blown off is discharged from waste material discharging opening 7.The inside of rotary screen 2 is inserted with rotary shaft 4, described rotation
One end of rotating shaft 4 connects electric rotating machine 3 through rotary screen 2, and outer housing 5 surrounds the outside being arranged on rotary screen 2,
Multiple anti-block apparatus 8 it is uniformly arranged on outer housing 5 outer surface；Anti-block apparatus 8 is main by multiple pulsed air big guns
Composition；The material of blocking regularly can be cleared up by such design by pulsed air big gun.Two grades
Sieve compartment 10 and discharge gate 11 that screening plant mainly by equal flitch 9, is positioned at equal flitch 9 lower end form；All
Flitch 9 is arranged on the lower end of rotary screen 2, and discharge gate 11 is arranged on the lower end of sieve compartment 10, sieve compartment 10
For blower port 12, air inducing port 13, long-pending adjustable plate 14 and the regulation hands of joining, one screening of 15 compositions is held
Chamber, blower port 12 and air inducing port 13 level of relative arrange, and long-pending join adjustable plate 14 and is movably arranged on air blast
Port 12 and the middle part of air inducing port 13, regulation hands is fixedly connected on the long-pending lower end joining adjustable plate 14 15.
In order to realize the accurate screening of material proportion, therefore at the external aerator of blower port 12, at air inducing port
External air-introduced machine.
In order to effectively prevent being directly entered two grades of screening districts, impact screening effect without the material once sieved
Really, therefore being additionally provided with flash testing agency 16 in the side of two grades of screening plants, flash testing agency 16 is arranged
Lower end at charging aperture 6.Flash testing agency 16 is rotary level-sensing device.
In order to by clean for the dust absorbing of generation in rotary screen 2 running, therefore also can set on outer housing 5
It is equipped with and connects air-vent 17.
Dust and Impurity Absorption in order to be produced by normal for rotary screen operation fall, therefore are connecing outside air-vent 17
Connect air-introduced machine.
Operator can be apparent from the ruuning situation of rotary screen 2, and convenient rolling later for convenience
The maintenance of shaft screen 2, therefore on outer housing 5, it is additionally provided with observation door 18.
The operating process explanation of flash testing agency 16:
Owing to charging aperture 6 is arranged on outer housing 5, there is spacing between outer housing 5 and rotary screen 2, work as material
From charging aperture 6 adds when, the material of part can flow to two grades of screening districts along with gap, so can be serious
Having influence on the effect of screening, on outer housing 5, the position in corresponding gap arranges flash testing agency 16, employing
It it is rotary level-sensing device structure.When not in contact with the when of to material, motor can run well；Work as stuff level switch
Blade when touch material, motor can drive microswitch action, exports control signal, cuts off horse
Reach power supply, cut off charging.
The operating process explanation of anti-block apparatus 8:
Anti-block apparatus 8 is mainly become by multiple pulsed air batterys；Pulsed air big gun is that one can be in wink
Between discharge a large amount of compressed air formed impact type gas big gun, tamper regularly can be cleared up.This
Arranging 8 pulsed air big guns in utility model altogether, the spacing between them is 0.5m.Work as pulsed air
After tamper is blown down by big gun, owing to rotary screen 2 is horizontal by 5 °～10 °, the tamper of whereabouts can fall
To one end of low level, finally discharge from waste material discharging opening 7.
The operating process explanation of two grades of screening plants:
As it is shown on figure 3, the material after sieving through rotary screen 2 can drop on equal flitch 9, equal flitch 9
Effect be can make from rotary screen sieve material pass from equal flitch 9 after can fall uniformly, under
The material fallen enters in sieve compartment 10, during falling, and the horizontally disposed aerator material to falling
Blowing, the air-introduced machine that relative aerator is arranged carries out air draught to material, the material of the material small particles of whereabouts
Can be affected by the long-pending opposite side joining adjustable plate 14, namely drop in the side away from aerator, in material
The dust existed then can be taken out of by air-introduced machine, and the material that granule is big is affected by little due to deadweight, can be close
The side of aerator falls, and material can be separated discharge from discharging opening respectively by long-pending adjustable plate 14 of joining, and thus may be used
To accomplish the screening of the accurate proportioning of material.When needs regulate material proportion therein when, can pass through
Regulation hands regulates to amass 15 joins the distance between adjustable plate 14 and aerator, it is possible to change variable grain
The blanking direction of size material, meets the component proportion of different material.
Although the foregoing describing detailed description of the invention of the present utility model, but those skilled in the art should
Working as understanding, these are merely illustrative of, and present embodiment can be made various changes or modifications, and do not carry on the back
From principle of the present utility model and essence, protection domain of the present utility model is only limited by the claims that follow.
