Abstract
The invention discloses a vibrating screen enables powder materials to be uniformly distributed on a mesh. The vibrating screen comprises an upper shell, a lower shell, the mesh between the upper shell and the lower shell, a support below the lower shell, and a vibrating motor for driving the upper and lower shells to vibrate, wherein a spring is arranged between the lower shell and the support, a feeding hole is formed in the upper shell, a discharging hole is formed in the lower shell, and a buffer and homogenization net is arranged on the inner wall of the upper shell and is positioned above the mesh. The vibrating screen has the advantages that the direct impact of the powder materials to the mesh is reduced by virtue of the buffer and homogenization net above the mesh, so that the powder materials can uniformly fall on the mesh, and the working efficiency of the mesh is improved.
Description
Technical field
The present invention relates to a kind of vibratory sieve for superfine powder.
Background technology
Reciprocating sieve optional equipment in current known various superfine powder engineering, all adopt reciprocating sieve, airflow screen and revolve riddler etc., but in actual superfine powder engineer applied, due to superfine powder, to there is proportion little, poor fluidity and easily building bridge, caking, simultaneously, material skewness on screen cloth of charging aperture, formed and pile up, thus be difficult to make that material is smooth and easy passes through screen cloth, once blocking screen cloth probably damages vibratory sieve, pollute to production environment, directly jeopardize health, and affect screening effeciency, also the generation of the accidents such as motor damage may be caused, affect normal manufacturing schedule, cause economic loss.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of vibratory sieve that powder is evenly distributed on screen cloth.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of vibratory sieve, comprise upper shell, lower house, be arranged on screen cloth between upper shell and lower house, be arranged on the support below lower house and drive the vibrating motor of upper shell, lower house vibration, spring is provided with between lower house and support, upper shell is provided with charging aperture, lower house is provided with discharging opening, described charging aperture and discharging opening in the vertical direction are positioned at a straight line, upper enclosure inner wall are provided with buffering homogenizing net and cushion homogenizing net to be positioned at above screen cloth.
Described upper shell is also provided with the laminar flow plate in evolvent type from upper shell center, laminar flow plate is between screen cloth and buffering homogenizing net, and laminar flow plate upper end is connected with the inwall of upper shell;
Described upper enclosure inner wall is provided with some nozzles, and screen cloth is aimed in the gas outlet of nozzle;
Be provided with bracing frame between described upper and lower casing, spherically shape of arching upward in the middle of screen cloth is fitted on bracing frame.
The invention has the beneficial effects as follows: after buffering homogenizing net is set above screen cloth, reduces powder and directly screen cloth is impacted, thus powder is evenly fallen on screen cloth, improve the operating efficiency of screen cloth.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1 and Figure 2, vibratory sieve of the present invention, comprise upper shell 1, lower house 2, the vibrating motor 5 that is arranged on screen cloth 3 between upper shell 1 and lower house 2, is arranged on the support 4 below lower house 2 and drives upper shell 1, lower house 2 to vibrate, vibrating motor 5 is two and lays respectively at upper shell 1 both sides.Spring 6 is provided with between lower house 2 and support 4, the upper surface of upper shell 1 is provided with charging aperture 7, the lower surface of lower house 2 is provided with discharging opening 8, described charging aperture 7 and discharging opening 8 in the vertical direction are positioned at a straight line, upper shell 1 inwall are provided with buffering homogenizing net 9 and cushion homogenizing net 9 to be positioned at above screen cloth 3.As shown in Figure 3, on screen cloth 3, accumulation is formed in order to prevent powder, upper shell 1 is also provided with the laminar flow plate 10 in evolvent type from upper shell 1 center, laminar flow plate 10 is between screen cloth 3 and buffering homogenizing net 9, laminar flow plate 10 upper end is connected with the inwall of upper shell 1, laminar flow plate 10 can stop powder vibrations heap sum gradually to develop loose, thus improves the utilization rate of screen cloth.Upper shell 1 inwall is provided with some nozzles 11, screen cloth 3 is aimed in the gas outlet of nozzle 11, the powder of poor fluidity forms steady rest bridge construction in screen cloth 3 surface, air-flow can be produced after being provided with nozzle 11 puncture bridge formation powder and be convenient to sub-sieve, when actual production, can at the lower edge of laminar flow plate 10 (laminar flow plate 10 is upper edge with the limit of upper shell 1 contact internal walls) upper soldering blow tube 13, nozzle 11 is arranged on jet pipe 13.In order to increase circulation screening area, be provided with bracing frame 12 between described upper shell 1 and lower house 2, spherically shape of arching upward in the middle of screen cloth 3 is fitted on bracing frame 12.
The course of work of the present invention is: superfine powder material screens, first buffering homogenizing net 9 is entered by charging aperture 7, work screen cloth 3 surface is evenly diffused to through buffering homogenizing net 9, under falling into the effect of the exciting force that powder on screen cloth 3 surface produces at vibrating motor 5, powder is upwards thrown on compass screen surface 3, moving linearly in horizontal direction simultaneously, the follow-up powder fallen into can produce superposition and pile up, affect screening effeciency, carry out segmentation by laminar flow plate to the powder that superposition is piled up to extend and guiding, make powder again be distributed in screen cloth 3 surface, again improve screen cloth utilization rate.Be aided with nozzle 11 and spray compressed air off and on, making large area bridge formation powder be punctured porous instantaneously helps gas body and suitable powder by screen cloth 3 to be formed, to prevent from causing equipment to be damaged because of powder accumulated plugging, therefore, this invention equipment in powerful disposal ability, reduce the advantage such as energy consumption and fault rate, extension device service life and occupy in various screening plant and cannot replace status and practical value.
