Abstract
The invention relates to a vibrating screen. The vibrating screen comprises an upper shell, a lower shell, a screen net arranged between the upper shell and the lower shell, a bracket arranged below the lower shell and a vibrating motor used for driving the upper shell and the lower shell to vibrate, wherein a spring is arranged between the lower shell and the bracket, a feeding opening is formed in the upper shell, and a discharging opening is formed in the lower shell. The vibrating screen is characterized in that a laminar flow plate which is in an involute form from the center of the upper shell is further arranged on the upper shell, and the upper edge of the laminar flow plate is connected with the inner wall of the upper shell. The vibrating screen has the advantages that segmental extension and guide are carried out on a stacked and accumulated powder material by using the laminar flow plate, and the powder material is then uniformly distributed on the surface of the screen net, so that the utilizing rate of the screen net is fully improved.
Description
Technical field
The present invention relates to a kind of reciprocating sieve.
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 reciprocating 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
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of reciprocating sieve.
Described a kind of reciprocating 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, it is characterized in that: described upper shell is also provided with the laminar flow plate in evolvent type from upper shell center, laminar flow plate upper edge is connected with the inwall of upper shell.
Described a kind of reciprocating sieve, is characterized in that described upper enclosure inner wall being provided with buffering homogenizing net and buffering homogenizing net is positioned at above screen cloth, and laminar flow plate is between screen cloth and buffering homogenizing net.
Described a kind of reciprocating sieve, is characterized in that described upper enclosure inner wall is provided with some nozzles, and screen cloth is aimed in the gas outlet of nozzle.
Described a kind of reciprocating sieve, is characterized in that being provided with bracing frame between described upper shell, lower house, and spherically shape of arching upward in the middle of screen cloth is fitted on bracing frame.
The invention has the beneficial effects as follows: utilize laminar flow plate to carry out segmentation to the powder that superposition is piled up and extend and guiding, make powder again be distributed in screen surface, thus fully improve screen cloth utilization rate.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
As shown in Figure 1 and Figure 2, reciprocating 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.Be provided with spring 6 between lower house 2 and support 4, the upper surface of upper shell 1 be 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.As shown in Figure 3, on screen cloth 3, accumulation is formed in order to prevent powder, upper shell 1 is also provided with by the laminar flow plate 10 in evolvent type from upper shell 1 center, laminar flow plate 10 upper edge 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.In order to make powder be evenly distributed on screen cloth, upper shell 1 inwall is provided with buffering homogenizing net 9 and buffering homogenizing net 9 is positioned at above screen cloth 3, laminar flow plate 10 is between screen cloth 3 and buffering homogenizing net 9.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 10 to the powder that superposition is piled up to extend and guiding, powder is made again to 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.
