Abstract
The invention discloses a vibrating screen with an enlarged circulation screening area. The vibrating screen comprises an upper shell, a lower shell, a screen mesh, a bracket and a vibrating motor, wherein the screen mesh is arranged between the upper shell and the lower shell; the bracket is arranged below the lower shell; the vibrating motor drives the upper shell and the lower shell to vibrate; a spring is arranged between the lower shell and the bracket; the upper shell is provided with a feed port; the lower shell is provided with a discharge port; a support frame is arranged between the upper shell and the lower shell; and the middle of the screen mesh is cambered into a spherical shape to be adhered to the support frame. According to the vibrating screen, the area of the screen mesh can be enlarged after the screen mesh is adhered to the support frame in the spherical shape so that the utilization ratio of the screen mesh can be increased, and therefore the production efficiency can be improved.
Description
Technical field
The present invention relates to a kind of reciprocating sieve for superfine powder.
Background technology
Reciprocating sieve optional equipment in the present known various superfine powder engineerings, all adopt reciprocating sieve, airflow screen and revolve riddler etc., but in actual superfine powder engineering is used, because superfine powder exists proportion little, poor fluidity and easily building bridge, caking, simultaneously, the material of charging aperture skewness on screen cloth, form and pile up, thereby be difficult to make material smooth and easy by screen cloth, probably damage reciprocating sieve in case stop up screen cloth, pollute to production environment, directly jeopardize health, and affect screening effeciency, also may cause the generation of the accidents such as motor damage, affect normal manufacturing schedule, economic loss.
Summary of the invention
Technical problem to be solved by this invention is: a kind of reciprocating sieve that increases circulation screening area is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of reciprocating sieve, comprise upper shell, lower house, be arranged on the vibrating motor that the screen cloth between upper shell and the lower house, the support that is arranged on the lower house below and driving upper shell, lower house vibrate, be provided with spring between lower house and the support, be provided with charging aperture on the upper shell, be provided with discharging opening on the lower house, be provided with bracing frame between the described upper and lower casing, arching upward in the middle of the screen cloth is spheric and is fitted on the bracing frame.
Be provided with buffering homogenizing net on the described upper enclosure inner wall and cushion the homogenizing net and be positioned at the screen cloth top;
Also be provided with the laminar flow plate that begins to be evolvent type from the upper shell center on the described upper shell, the laminar flow plate is between screen cloth and buffering homogenizing net, and laminar flow plate upper edge links to each other with the inwall of upper shell;
Be provided with some nozzles on the described upper enclosure inner wall, screen cloth is aimed in the gas outlet of nozzle.
The invention has the beneficial effects as follows: can increase the area of screen cloth after screen cloth being fitted on the bracing frame that is spheric, thereby can improve the utilization rate of screen cloth, thereby enhance productivity.

Among the figure: 1, upper shell, 2, lower house, 3, screen cloth, 4, support, 5, vibrating motor, 6, spring, 7, charging aperture, 8, discharging opening, 9, buffering homogenizing net, 10, the laminar flow plate, 11, nozzle, 12, bracing frame, 13, jet pipe.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1 and Figure 2, reciprocating sieve of the present invention, the vibrating motor 5 that comprise upper shell 1, lower house 2, be arranged on the screen cloth 3 between upper shell 1 and the lower house 2, the support 4 that is arranged on lower house 2 belows and driving upper shell 1, lower house 2 vibrates, vibrating motor 5 is two and lays respectively at upper shell 1 both sides.Be provided with spring 6 between lower house 2 and the support 4, be provided with charging aperture 7 on the upper surface of upper shell 1, be provided with discharging opening 8 on the lower surface of lower house 2, described charging aperture 7 and discharging opening 8 in the vertical directions are positioned at a straight line.In order to increase circulation screening area, be provided with bracing frame 12 between described upper shell 1 and the lower house 2, arching upward in the middle of the screen cloth 3 is spheric and is fitted on the bracing frame 12.As shown in Figure 3, pile up in order to prevent that powder from forming at screen cloth 3, also be provided with the laminar flow plate 10 that begins to be evolvent type from upper shell 1 center on the upper shell 1, laminar flow plate 10 upper edges link to each other with the inwall of upper shell 1, laminar flow plate 10 can stop the powder vibrations to be piled up and gradually exploitation is loose, thereby improves the utilization rate of screen cloth.For powder is evenly distributed at screen cloth, be provided with buffering homogenizing net 9 on upper shell 1 inwall and buffering homogenizing net 9 is positioned at screen cloth 3 tops, laminar flow plate 10 is between screen cloth 3 and buffering homogenizing net 9.Be provided with some nozzles 11 on upper shell 1 inwall, screen cloth 3 is aimed in the gas outlet of nozzle 11, the powder of poor fluidity forms the steady rest bridge construction in screen cloth 3 surfaces, be provided with and produce air-flow behind the nozzle 11 and puncture the bridge formation powder and be convenient to sub-sieve, when actual production, can go up soldering blow tube 13 in the lower edge of laminar flow plate 10 (limit that laminar flow plate 10 contacts with upper shell 1 inwall is the upper edge), nozzle 11 is arranged on the jet pipe 13.
The course of work of the present invention is: the screening of superfine powder material, at first enter buffering homogenizing net 9 by charging aperture 7, evenly diffuse to work screen cloth 3 surfaces through buffering homogenizing net 9, fall into screen cloth 3 lip-deep powders under the effect of the exciting force that vibrating motor 5 produces, powder is upwards thrown on compass screen surface 3, moving linearly on the while horizontal direction, the follow-up powder that falls into can produce stack and pile up, affect screening effeciency, cut apart extension and guiding by the powder that 10 pairs of stacks of laminar flow plate are piled up, make powder again be distributed in screen cloth 3 surfaces, again improve the screen cloth utilization rate.Be aided with nozzle 11 and spray off and on compressed air, making large tracts of land bridge formation powder be punctured porous by moment helps gas body and suitable powder to pass through screen cloth 3 with formation, to prevent that piling up obstruction because of powder causes the equipment damage, therefore, this invention equipment in powerful disposal ability, reduce the advantage such as energy consumption and fault rate, extension device service life and in various screening plants, occupy and can't replace status and practical value.
