Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing clogging of a mesh of vibration nodes of granular materials such as minerals and plants.

Conventional vibrating ring meshes (silk with only meridian lines) become clogged with powder during use, resulting in poor nodal efficiency.

In order to prevent this, some types have a brush attached to the bottom of the silk for cleaning, but the mechanism is complicated. Another disadvantage is that if the operation is stopped and cleaning is performed, the operating rate decreases. This invention is intended to improve the above-mentioned shortcomings, and aims to improve the operating rate by reducing the tension of the meridian of the vibration of the frame and allowing clogging powder to fall through the screen during work.

To describe this invention with reference to drawings showing one embodiment, in FIGS. 1 to 4, a main body 1 having a vibrating device 3; a wire mesh 2 formed only of meridians provided on the wire main body 1;
A device for preventing blindness of a fender, comprising: a device for hooking one end to the main body 1; a device for hooking the pond end of the wire mesh 2 to the main body 1, and a device for tensioning or loosening the wire mesh 2. be.

To explain this in detail, the main body 1 is provided with several stages of wire meshes 2, and the vibrating device 3 on the upper part is operated to divide the powder into sections by the wire meshes 2. Large grains are separated using the wire mesh on the upper tier, and smaller grains are successively separated using the wire mesh on the lower tier. The wire mesh 2 has a large number of linear wire meshes arranged horizontally, and hooks 4 at the top of the wire mesh 2
is hung on a hook hanging fitting 5, and the lower hook 6 is hung on a hanging fitting 7 of a lower fixed pipe 8.

The middle of the wire mesh 2 is supported by a fixed pipe 8 and a vibrating pipe 9. The details of the hook hanging fitting 5 will be explained with reference to FIG. 3. A rectangular pipe 12 having a vertical support plate 11 is fixed to the side plate 10' of the machine frame, and a plurality of bolts 13 are slidably attached to the support plate 11. A spring 15 is provided at one end of the bolt 13 via a cylindrical cover 14, and the bolt 13 is pulled by compressing the spring 15 with a nut 13' in the cylindrical cover 14.
A square plate 16 is fixed to the other end of the bolt 13, and the hook 4 of the net 2 is hung on the tip of the square plate 16. In FIG. 4, a plurality of cylindrical covers 14 are integrated by a connecting plate 17,
A fluid cylinder 18 is fixed in the hole of the connecting body 17, and the rod 20 of the piston 19 of the fluid cylinder 18 is attached to the support plate 1.
1.

To explain the operation of this invention, the vibration device 3 is operated,
Powder and granular material is supplied onto the wire mesh 2 in the direction of arrow AI in FIG.

The powder and granules are separated by a wire mesh 2.

During ring separation, as shown in FIG. 4, when hydraulic pressure is applied to the cylinder 18 and the tip of the rod 20 pushes the support plate 11, the cylindrical cover 14 is separated from the support plate 11 by a length of 1, and the corner plate 16 is also moved as shown by arrow AI6. direction, tensioning the wire mesh 2.

If powder is caught between the lines of the wire mesh 2 during the knotting operation and the efficiency of the knotting work is reduced, reduce the oil pressure of the cylinder 18 and the cylindrical cover 14 will move in the opposite direction of arrow AI6, as shown in Figure 3. It comes into contact with the support plate 11 as shown in FIG.

Therefore, the square plate 16 moves together with the bolt, and the tension of the wire of the wire mesh 2 is relaxed. In addition, in the one shown in Fig. 3, the nut 13'
By loosening , the tension on the wire mesh 2 is loosened.

When the main body 1 is vibrated in this relaxed state, since the wire mesh 2 is formed only from meridian lines, the distance between the meridian lines is widened, and therefore powder particles between the lines or attached to the lines are Powder is falling down. Once the powder has fallen, hydraulic pressure is applied to the cylinder 18 to tighten the silk and continue the sectioning process. Since the present invention has the above-described configuration, the vibration of the binder is used while the binder is in operation, and the wires of the wire mesh are loosened to cause the powder adhering to the wire mesh 2 to fall. It is possible to prevent clogging and improve sorting efficiency.
