Abstract
The invention relates to a vibrating screen for powder materials. The vibrating screen comprises an upper shell body, a lower shell body, a screen cloth arranged between the upper shell body and the lower shell body, supporting frames arranged on the lower portion of the lower shell body and vibrating motors driving the upper shell body and the lower shell body to vibrate. Springs are arranged between the lower shell body and the supporting frames; a feeding inlet is formed in the upper shell body; and a discharging outlet is formed in the lower shell body. The vibrating screen is characterized in that the upper shell body is further provided with a laminar flow plate which is in an involute mode from the center of the upper shell body, and the upper edge of the laminar flow plate is connected with the inner wall of the upper shell body. The vibrating screen has the beneficial effects that the overlaid and accumulated powder materials are partitioned, extended and guided through the laminar flow plate, and the powder materials are uniformly distributed on the surface of the screen cloth again, so that the utilization rate of the screen cloth is fully increased.
Description
Technical field
The present invention relates to a kind of powder material reciprocating sieve.
Background technology
Screening installation is shaken in currently known various superfine powder engineerings, using reciprocating sieve, airflow screen and rotation riddler
Deng, but in actual superfine powder engineer applied, have that proportion is little due to superfine powder, poor fluidity and easily build bridge, lump,
Meanwhile, the material of the charging aperture skewness on screen cloth is formed and piled up, so as to be difficult to make material smooth by screen cloth, once it is stifled
Plug screen cloth is likely to damage reciprocating sieve, pollutes to production environment, directly jeopardizes health, and affects screening efficiency,
It is likely to cause the generation of the accidents such as motor damage, affects normal manufacturing schedule, causes economic loss.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of technology of powder material reciprocating sieve
Scheme.
A kind of described powder material reciprocating sieve, including upper shell, lower house, be arranged between upper shell and lower house
Screen cloth, the support being arranged on below lower house and driving upper shell, the vibrating motor of lower house vibration, between lower house and support
Spring is provided with, charging aperture is provided with upper shell, discharging opening is provided with lower house, it is characterised in that：On the upper shell
It is additionally provided with from upper shell center and starts the laminar flow plate in evolvent type, laminar flow plate upper edge is connected with the inwall of upper shell.
A kind of described powder material reciprocating sieve, it is characterised in that be provided with the upper enclosure inner wall buffering homogenizing net and
Buffering homogenizing net is located at screen cloth top, and laminar flow plate is located between screen cloth and buffering homogenizing net.
Described a kind of powder material reciprocating sieve, it is characterised in that some nozzles are provided with the upper enclosure inner wall, spray
The gas outlet alignment screen cloth of mouth.
Described a kind of powder material reciprocating sieve, it is characterised in that be provided with bracing frame between the upper shell, lower house,
The spherical shape that arches upward in the middle of screen cloth is fitted on bracing frame.
The invention has the beneficial effects as follows：The powder that superposition is piled up is carried out using laminar flow plate split extension and guiding, make powder
Material is distributed in again screen surface, so as to fully improve screen cloth utilization rate.

Specific embodiment
With reference to Figure of description, the present invention will be further described：
It is shown as shown in Figure 1, Figure 2, reciprocating sieve of the present invention, including upper shell 1, lower house 2, it is arranged on upper shell 1
And the screen cloth 3 between lower house 2, be arranged on the support 4 of the lower section of lower house 2 and drive upper shell 1, lower house 2
The vibrating motor 5 of vibration, vibrating motor 5 is for two and respectively positioned at the both sides of upper shell 1.It is provided between lower house 2 and support 4
Spring 6, is provided with charging aperture 7 on the upper surface of upper shell 1, discharging opening 8, the charging are provided with the lower surface of lower house 2
Mouth 7 and the in the vertical direction of discharging opening 8 are located at a straight line.As shown in Fig. 3, in order to prevent powder shape on screen cloth 3
Into accumulation, the laminar flow plate 10 in evolvent type, the top of laminar flow plate 10 by from the center of upper shell 1 are additionally provided with upper shell 1
Along being connected with the inwall of upper shell 1, powder vibrations can be prevented to pile up for laminar flow plate 10 and gradually exploitation dissipates, so as to improve screen cloth
Utilization rate.In order that powder is evenly distributed on screen cloth, buffering homogenizing net 9 is provided with the inwall of upper shell 1 and is buffered equal
Change net 9 and be located at the top of screen cloth 3, laminar flow plate 10 is located between screen cloth 3 and buffering homogenizing net 9.If being provided with the inwall of upper shell 1
Dry nozzle 11, the gas outlet alignment screen cloth 3 of nozzle 11, the powder of poor fluidity forms stable in the surface of screen cloth 3
Bridging structure, is provided with after nozzle 11 to produce air-flow and puncture bridge formation powder and is easy to sub-sieve, in actual production, can be in laminar flow
The lower edge of plate 10（The side that laminar flow plate 10 is contacted with the inwall of upper shell 1 is upper edge）Upper soldering blow tube 13, nozzle 11
It is arranged on jet pipe 13.In order to increase circulation screening area, between the upper shell 1 and lower house 2 bracing frame is provided with
12, the spherical shape that arches upward in the middle of screen cloth 3 is fitted on bracing frame 12.
The present invention the course of work be：Superfine powder material is screened, and enters buffering homogenizing net 9 by charging aperture 7 first,
Buffered homogenizing net 9 uniformly diffuses to the surface of work screen cloth 3, and the powder fallen on the surface of screen cloth 3 is in swashing that vibrating motor 5 is produced
In the presence of power of shaking, powder is set to be thrown upwards on compass screen surface 3, at the same it is for linear motion in horizontal direction, subsequently fall into
Powder can produce superposition and pile up, and affect screening efficiency, and the powder piled up by the 10 pairs of superpositions of laminar flow plate is carried out splitting extension and led
Draw, make powder be distributed in the surface of screen cloth 3 again, screen cloth utilization rate is improved again.It is aided with nozzle 11 and sprays compression off and on
Air, makes large area bridge formation powder moment be punctured porous to form fluidizer gas with suitable powder by screen cloth 3, in case
Only equipment is caused to be damaged because of powder accumulated plugging, therefore, the invention equipment is in powerful disposal ability, reducing energy consumption and failure
The advantages of rate, extension device service life, is occupied in various screening plants and cannot replace status and practical value.
