Screen device

The present invention relates to a screen device, and more particularly to a screen device in which the outer peripheral wall of the screen frame body is provided with a flange for holding the screen.

The vibrating screen machine is used for screening a sieve having minerals or crops having different particle sizes, and has a plurality of screens overlapping each other, each screen having a different mesh size, when the sieve passes through the sieves When the screen is meshed, the vibrating screen machine vibrates the screen, so that the particles smaller in size than the screen mesh can pass, and the particles larger than the mesh mesh will remain on the screen, so that the size of the sieve can be made. Screening and classification.

Referring to FIGS. 5 and 6, a conventional screen device 100 includes an upper frame 10, a lower frame 20, and a screen 30. The upper frame 10 and the lower frame 20 are both cylindrical and identical. The diameter of the upper flange 12 projects inwardly from the bottom edge of the upper frame 10. Similarly, the lower flange 22 projects inwardly from the top edge of the lower frame 20, and a plurality of through holes 16 are formed in the upper flange 12. A plurality of screw holes 26 are formed in the lower flange 22, and the upper frame 10 is coupled to the lower frame 20 by the bolt 5 passing through the through hole 16 and screwed to the screw hole 26, and the upper flange 12 and the lower protrusion are formed. The edge 22 clamps the fixed screen 30, and after the material falls to the screen 30, after shaking, the material of the mesh size smaller than the screen 30 passes through the screen 30, and the mesh of the size larger than the screen 30 accumulates on the screen 30. And discharged by the discharge port 14.

In the above configuration, since the upper flange 12 and the lower flange 22 are both disposed inside the upper frame 10 and the lower frame 20, the material may accumulate at the upper flange 12 when it falls into the screen device 100. In addition, if the screen 30 is to be replaced, it must be operated by the inside of the upper frame 10, which is limited by the empty space of the upper frame 10. It is inconvenient to change jobs. Moreover, when the plurality of screen devices 100 are overlapped, it is inconvenient to replace the screen device after the lower screen has to be removed one by one.

In view of this, the purpose of the present invention is to provide a screen device in which the flange is disposed on the outer peripheral wall of the frame body, and when the material falls in the frame of the screen device, there is no problem of accumulation, and it can be externally Screen replacement is convenient for replacement work.

The main technical means for achieving the above purpose is that the screen device comprises: a first frame; a first flange protruding outward from the outer peripheral wall of the first frame; and a second frame corresponding to a first frame; a second flange protruding outward from the outer peripheral wall of the second frame; and a screen disposed between the first frame and the second frame, and the first frame A flange is clamped to the second flange.

The advantage of the present invention is that the flange is formed on the outer peripheral wall of the frame, and when the material is dropped into the frame, there is no problem of material accumulation. When the screen is replaced, the outer part of the frame can be carried out. Very convenient. Even if a plurality of screen devices are stacked, when the lower screen is to be replaced, the replacement work can be directly performed from the outside without removing the upper screen devices one by one.

Referring to FIG. 1 and FIG. 2 , the screen device 200 of the present invention mainly includes a first frame 110 , a second frame 120 , and a screen 130 . The first frame body 110 and the second frame body 120 are both cylindrical and have the same diameter. A first flange 112 is formed at the edge of the bottom of the first frame body 110, and the first flange 112 is from the first frame. The outer peripheral wall of the body 110 extends toward the outside, and a second flange 122 is formed at the edge of the top of the second frame 120. The second flange 122 extends outward from the outer peripheral wall of the second frame 120, and the screen 130 is clamped. The first flange 112 and the second flange 122 are locked by a plurality of bolts 7 so that the first frame 110 is coupled to the second frame 120, The screen 130 is fixed between the first frame 110 and the second frame 120.

Referring to FIGS. 2 to 4, a rib 116 is formed on the first flange 112. The rib 116 protrudes away from the first frame 110, and the plurality of first through holes 118 extend through the first flange 112 and the convex portion. The rib 116 has a first recessed portion 124 and a second recessed portion 126 formed on the second flange 122. The depth of the first recessed portion 124 is greater than the second recessed portion 126, and the second recessed portion 126 is positioned first. The position of the recess 124 is close to the second frame 120. A plurality of screw holes 128 are formed at the bottom of the first recessed portion 126, and the screw holes 128 correspond to the first through holes 118.

Referring to FIG. 4, when the screen device 200 is assembled, the screen 130 is clamped between the first flange 112 and the second flange 122, and is respectively pushed by the rib 116 of the first flange 112. a ring body 140, the bottom surface of the first flange 112 pushes a second ring body 150, and the first ring body 140 and the second ring body 150 respectively press the edges of the screen mesh 130 to the first recess portion 124 and The bottom of the second recess 126 forms a plurality of second through holes 148 on the first ring body 140. The second through holes 148 correspond to the first through holes 118 and the screw holes 128. The first ring body 140 can be a steel ring, the second ring body 150 can be a rubber ring, and the second ring body 150 can be pressed against the screen. The net 130 is provided with a force of the screen 130 so that the screen 130 is horizontally clamped between the first flange 112 and the second flange 122, and sequentially passes through the first through hole 118 and the first through the bolt 7. The two through holes 148 are screwed into the screw holes 128 to fix the screen 130 between the first flange 112 and the second flange 122.

When the material falls on the screen device 200, the material having a size smaller than the screen 130 passes through the screen 130, and the mesh having a size larger than the screen 130 accumulates on the screen 130 and is discharged by the discharge port 114.

Since the screen device of the present invention has the first flange 112 and the second flange 122 respectively disposed on the outer peripheral walls of the first frame 110 and the second frame 120, when the material falls into the frame, there is no The problem of material accumulation, when the screen is to be replaced, can be carried out from the outside of the frame, which is quite convenient. Even if a plurality of screen devices are stacked, when the lower screen is to be replaced, the replacement work can be directly performed from the outside without removing the upper screen devices one by one.

The present invention is disclosed in the above embodiments, but it is not intended to limit the scope of the present invention. Anyone skilled in the art can make some changes and refinements without departing from the spirit of the present invention. The scope of protection is subject to the definition of the scope of the patent application attached.
