Technical field
The present invention relates to chemical plant installations, and in particular to a kind of strength particle screen selecting device.
Background technique
Screening i.e. will using sieveGranularityThe operation that the particle swarm of wider range is screened by granularity (or volume), it is a kind of
The operation for being separated solid material by required granular size using the different sieve of screen size.Screening apply in general to compared with
Thick material is greater than 0.5 or 0.25 millimeter of material.Particle swarm mainly presses its granularity or volume separation, specific gravity and shape when screening
The influence of shape is smaller.Screening plant is widely used in various industrial departments, thus there are many type of screening plant, there is no so far
Unified classification standard.Current screening plant mainly includes following 6 seed type, respectively gravity flow screen, roller picker, rotary screen,
Shaker screen, vibrating screen and other novel screening plants.
In engineering practice mainly by the relative motion of particle and compass screen surface so that the material of different-grain diameter pass through it is different
Sieve pore, to realize the purpose of particle screening, currently used is vibrosieve equipment.
Vibrating screen is current many most widely used screening plants of industrial department.Vibrating screen has band as shaker screen
The rectangle screen box of plane compass screen surface, but screen box supports (or hanging) on the rack with elastic element and carries out exciting with vibration excitor, because
And it is an elastic oscillating system, amplitude is by being fed and other kinetic factors are influenced, thus it is possible to vary.The vibration of vibrating screen
Dynamic frequency is high, amplitude is small, material makees jumping on compass screen surface, thus processing capacity and screening efficiency are all higher.Vibrating screen is suitable
For each grade material classification and in, the dehydration of fine fraction coal, desliming and de-mediated.
But existing vibrating screen, is primarily present following problems:
1, in order to meet screening effect, longer oscillation distances are needed, relatively thin stratum granulosum thickness takes up a large area；
2, particle is vibrated in vibration processes, is collided with compass screen surface, particle easy to damage；
3, in screening process, a large amount of flying dust can be generated, screening effect is poor.
Summary of the invention
For technical problem of the existing technology, the present invention provides a kind of strength particle screen selecting devices.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of strength particle screen selecting device, the device include vibrator and shell, and the top of the shell is equipped with charging
Mouthful, bottom end is equipped with ash bucket；The screen slope is placed on the inside of shell, and filtrate is located at the inner sidewall of shell, the vibration
Dynamic device is connected with sieve and filtrate respectively, and bleeding point is located at the lateral wall of the shell, and the discharge port side low with sieve is connected.
In technical solution of the present invention: ash bucket is connected with ash hole.
In technical solution of the present invention: the tilt angle of sieve and horizontal plane is 0-15 °.
In technical solution of the present invention: discharge port is equipped with access hole.
In technical solution of the present invention: bleeding point is connected with blower.
In technical solution of the present invention: the device includes at least two vibrators, to control different vibration frequencies.
In technical solution of the present invention: the device includes the sieve of at least two different screen sizes.
In technical solution of the present invention: material to be sieved enters screening plant from feed inlet, and conforming particle is discharged from discharge port,
Remaining broken particle and dust are discharged from ash hole, and the gas that device includes fugitive dust is discharged after media filtration by bleeding point.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of strength particle screening device of the present invention；
Fig. 2 is the side view of strength particle screening device of the present invention；
Wherein: 1 is feed inlet, and 2 be shell, and 3 be sieve, and 4 be vibrator, and 5 be access hole, and 6 be discharge port, and 7 be filtrate,
