Description
Technical field
It is specifically a kind of without blocking rotary screen the present invention relates to rotary screen technical field.
Background technology
Rotary screen is the new sieve material equipment of a generation, is construction material, refractory material, coal, miberal powder, river sand classification, sandstone
The equipment being commonly used in block-grading.
1st, for material to be separated by fineness, the material the feed separation of thickness together into different fineness.
2nd, separated in sandstone field with sandstone.
3rd, coal industry separates for lump coal with the thickness of coal dust.
4th, Mineral Processing Industry, chemical industry are used for the classification of size block and separate flour.
5th, dispensing equipment is used for the granular materials for selecting reasonable fineness.
6th, removing not use material in raw material, ensure Product Precision.
It can be reached in screening process by the relative motion of combed sieve cleaning mechanism and sifting barrel to the uninterrupted cleaning of sieve nest
Effect, make sifting barrel remained in whole work process cleaning, it is not viscous, not stifled, do not influence screening effect.According to difference
Classification requires that rotary screen hierarchical level is typically from carefully to slightly being saved for 1-4, material is not from carefully to rough segmentation from first segment to last one section
Screen cloth is sifted out, and the material more than final section sieve screen apertures is discharged from discharging opening.The agent structure of rotary screen is sifting barrel.
But the existing easy screen cloth of sifting barrel is easy to be plugged.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, using high pressure air stream device, prevents screen drum to be blocked
Firmly.
To achieve the above object, a kind of jet shape is designed without blocking rotary screen, including the discharging of cylinder, charging aperture, screenings
Mouth, coarse fodder discharging opening, it is characterised in that：
Also include the high pressure air stream device for conveying high-pressure air；
Described high pressure air stream device is hung on above cylinder.
Described high pressure air stream device, which is provided with, to be included,
Gas transmission main provided with air inlet；
An at least branch pipe communicated with gas transmission main；
The threeway pipe device being connected with the port of export of every branch pipe；Described threeway pipe device is to be included in the bottom of a house steward
Face right dry heteromorphic connector uniform vertically is formed；
The playpipe being connected with the port of export of heteromorphic connector.
Described playpipe uses straight line playpipe, and its inwall is set to smooth or provided with long pitch screw, described length
Its pitch of pitch screw is 4~∞ times of jet diameters.
Totally tapered joint, the bigger diameter end of heteromorphic connector connect house steward, the path of heteromorphic connector to described heteromorphic connector
End connection playpipe.
Described gas transmission main is provided with control valve.
Described cylinder is in tilted layout；The feed inlet end of described cylinder is higher than the afterbody of cylinder.
Described high pressure air stream device is provided with pressure gauge.
Described cylinder is rearwardly divided into some sections from charging aperture and forms classification screen cloth on direction, and is classified the adjacent of screen cloth
Level from charging aperture, rearwardly successively decrease by its sieve mesh number of direction.
The present invention compared with the existing technology, high pressure air stream device is added above cylinder, screen cloth had both been added
Direct jet power, and high velocity air can also produce certain vibration force to screen cloth, further prevent the blocking of screen cloth, carry
High workload efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the partial structural diagram of mesohigh air-spray device of the present invention.
Fig. 3 is the partial enlarged drawing in Fig. 2.
Fig. 4 is the partial schematic diagram of another threeway pipe device in the embodiment of the present invention.
Embodiment
The present invention is further described in conjunction with accompanying drawing.
Referring to Fig. 1~Fig. 4, the present invention includes cylinder 2, charging aperture 4, screenings discharging opening 3, coarse fodder discharging opening 5, its feature
It is：
Also include the high pressure air stream device 1 for conveying high-pressure air；
Described high pressure air stream device 1 is hung on the top of cylinder 2.
Further, described high pressure air stream device 1 is provided with and included, the gas transmission main 1-2 provided with air inlet；At least
A piece branch pipe 1-3 communicated with gas transmission main 1-2；The threeway pipe device being connected with the every branch pipe 1-3 port of export；Described three
Pipe device is formed by the bottom surface right dry heteromorphic connector 1-12 uniform vertically for being included in a house steward 1-1；With heteromorphic connector 1-
The playpipe 1-13 of 12 port of export connection.
Further, described playpipe 1-13 uses straight line playpipe, and its inwall is set to smooth or provided with long pitch
Screw thread, described its pitch of long pitch screw are 2~4 times of jet diameters.Cathetus playpipe of the present invention refers to playpipe 1-
13 inwall is totally in cylinder.As to whether it is depending on material sticks type, if material is viscous using long pitch screw
Attached property is small, then can use the playpipe of smooth inner wall, if adhesiveness is big, using the playpipe of long pitch screw, uses
The playpipe of this structure, can make that the stability of the high pressure draught of injection is higher, impulse force is bigger, range is more remote.
Further, totally tapered joint, heteromorphic connector 1-12 bigger diameter end connection are total by described heteromorphic connector 1-12
Pipe 1-1, heteromorphic connector 1-12 miner diameter end connection playpipe 1-13.The heteromorphic connector of this structure can strengthen stream pressure,
The long pitch screw of inside pipe wall is sprayed by straight line again, the screen cloth of the straight air stream impact cylinder of ejection is reached the work of broken arch
With.
Further, described gas transmission main 1-2 is provided with control valve.
