Description
Technical field
The present invention relates to a kind of superfine powder material reciprocating sieve.
Background technology
Reciprocating sieve optional equipment in currently known various superfine powder engineering, all uses reciprocating sieve, airflow screen and rotation riddler
Deng, but in actual superfine powder engineer applied, due to superfine powder have that proportion is little, poor fluidity and easily build bridge, lump,
Meanwhile, the material of charging aperture skewness on screen cloth, formed and pile up, thus be difficult to make material smooth and easy by screen cloth, once block up
Plug screen cloth is likely to damage reciprocating sieve, pollutes to production environment, directly jeopardizes health, and affect screening efficiency,
It is likely to cause the generation of the accidents such as motor damage, affects normal manufacturing schedule, cause economic loss.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of superfine powder material reciprocating sieve
Technical scheme.
Described a kind of superfine powder material reciprocating sieve, including upper shell, lower house, be arranged on upper shell and lower house it
Between screen cloth, be arranged on the support below lower house and drive upper shell, lower house vibration vibrating motor, lower house and support
Between be provided with spring, upper shell is provided with charging aperture, lower house is provided with discharging opening, it is characterised in that: described upper casing
The laminar flow plate started in evolvent type it is additionally provided with from upper shell center, the inwall phase of laminar flow plate upper edge and upper shell on body
Even.
Described a kind of superfine powder material reciprocating sieve, it is characterised in that be provided with buffering homogenizing in described upper enclosure inner wall
Net and buffering homogenizing net are positioned at above screen cloth, and laminar flow plate is between screen cloth and buffering homogenizing net.
Described a kind of superfine powder material reciprocating sieve, it is characterised in that be provided with some sprays in described upper enclosure inner wall
Mouth, the gas outlet alignment screen cloth of nozzle.
Described a kind of superfine powder material reciprocating sieve, it is characterised in that be provided with between described upper shell, lower house and prop up
Support, the spherically 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 utilizing laminar flow plate to pile up superposition carries out segmentation and extends and guide, and makes powder
Material is distributed in screen surface again, thus fully improves screen cloth utilization rate.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
Shown in 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 screen cloth 3 between lower house 2, be arranged on the support 4 below lower house 2 and drive upper shell 1, lower house 2
The vibrating motor 5 of vibration, vibrating motor 5 is two and lays respectively at upper shell 1 both sides.It is provided with between lower house 2 and support 4
Spring 6, the upper surface of upper shell 1 is provided with charging aperture 7, and the lower surface of lower house 2 is provided with discharging opening 8, described charging
Mouth 7 and discharging opening 8 in the vertical direction are positioned at a straight line.As shown in Fig. 3, in order to prevent powder shape on screen cloth 3
Become to pile up, upper shell 1 is additionally provided with the laminar flow plate 10 in evolvent type by from upper shell 1 center, laminar flow plate 10 top
Along being connected with the inwall of upper shell 1, powder vibrations can be stoped to pile up for laminar flow plate 10 and gradually exploitation dissipates, thus improves screen cloth
Utilization rate.In order to make powder be evenly distributed on screen cloth, upper shell 1 inwall is provided with buffering homogenizing net 9 and buffering is equal
Changing net 9 and be positioned at above screen cloth 3, laminar flow plate 10 is between screen cloth 3 and buffering homogenizing net 9.If being provided with on upper shell 1 inwall
Dry nozzle 11, the gas outlet alignment screen cloth 3 of nozzle 11, the powder of poor fluidity is formed stable in screen cloth 3 surface
Bridging structure, can produce air-flow and puncture bridge formation powder and be easy to sub-sieve after being provided with nozzle 11, when actual production, and can be at laminar flow
Lower edge (laminar flow plate 10 is upper edge with the limit of upper shell 1 contact internal walls) the upper soldering blow tube 13 of plate 10, nozzle 11
It is arranged on jet pipe 13.In order to increase circulation screening area, between described upper shell 1 and lower house 2, it is provided with bracing frame
12, the spherically shape that arches upward in the middle of screen cloth 3 is fitted on bracing frame 12.
The work process of the present invention is: superfine powder material screens, and is first entered buffering homogenizing net 9 by charging aperture 7,
Buffered homogenizing net 9 uniformly diffuses to work screen cloth 3 surface, falls into the powder on screen cloth 3 surface at swashing that vibrating motor 5 produces
Under the effect of power of shaking, powder is made upwards to be thrown on compass screen surface 3, simultaneously for linear motion in horizontal direction, follow-up fall into
Powder can produce superposition and pile up, and affects screening efficiency, laminar flow plate 10 powder that superposition is piled up is carried out segmentation and extend and lead
Draw, make powder again be distributed in screen cloth 3 surface, again improve screen cloth utilization rate.It is aided with nozzle 11 and sprays compression off and on
Air, makes large area bridge formation powder be punctured porous by moment and passes through screen cloth 3 to form fluidizer gas with suitable powder, in case
Only causing equipment to be damaged because of powder accumulated plugging, therefore, this invention equipment is in powerful disposal ability, reduction energy consumption and fault
The advantages such as rate, extension device service life are occupied in various screening plants cannot replace status and practical value.
