Abstract
A vibration screening device comprises pore screen meshes which are fixed on four springs obliquely. Coarse screening meshes in parallel with the pore screen meshes are fixed above the pore screen meshes through vertical plates on two sides of the pore screen meshes, a pneumatic vibration mechanism is fixed at the lower sides of the pore screen meshes; a circular track and steel balls accommodated in the circular track are arranged in the pneumatic vibration mechanism; a compressed air inlet is formed at the lower-right part of the circular track; and a compressed air outlet is formed above the circular track. Compared with the traditional vibration mechanism, the pneumatic vibration mechanism of the vibration screening mechanism needs no complicated motors or driving mechanisms, so that the structure is simplified greatly, and the service life is longer.
Description
Technical field
The utility model relates to a kind of material separation device, particularly a kind of vibration screening device.
Background technology
Bead after dispellable mould casting steam batch (-type) prefoam machine is sent out in advance is often inhomogeneous because of original bead, and some especially little so-called dead beads will sieve.The adhesion of part bead inevitably will take place and forming fritter pre-sending out in the process, should separate being broken into single bead and better using, otherwise the bead of one-tenth piece can stop up narrow space in the spray gun, make the spray gun can't the filling die cavity in addition.Existing vibration screening device all is to adopt eccentric wheel to produce vibration, its vibrating mechanism complex structure, and the life-span is short.
The utility model content
For addressing the above problem, the utility model provides a kind of vibrating mechanism simple in structure, the vibration screening device that the life-span is long.
The utility model vibration screening device, comprise and tilt to be fixed on four pore screen clothes on the spring, the top of described pore screen cloth is fixed with gross porosity screen cloth in parallel by the vertical panel of its both sides, wherein, described fine ga(u)ge screen side off the net is fixed with pneumatic vibration mechanism, described pneumatic vibration mechanism inside is provided with circular track and is contained in wherein steel ball, and the lower right of described circular track is provided with compressed air inlet, and the top is provided with compressed air outlet.
The utility model vibration screening device, wherein, it is online that the bolting hole of described pneumatic vibration mechanism by its both sides, upper end is fixed on described fine ga(u)ge screen.
The pneumatic vibration mechanism of the utility model vibration screening device compares with existing vibrating mechanism, need not complicated motor and transmission mechanism, and structure is simplified greatly, and the life-span is longer.
Description of drawings
Fig. 1 is that the master of the utility model vibration screening device looks cutaway view;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the master of the pneumatic vibration mechanism of the utility model vibration screening device looks cutaway view.
The specific embodiment
Below in conjunction with Figure of description the utility model vibration screening device is described further.
Referring to Fig. 1-Fig. 2, the utility model vibration screening device comprises and tilts to be fixed on four pore screen clothes 2 on the spring 4 that the top of pore screen cloth 2 is fixed with gross porosity screen cloth 1 in parallel by the vertical panel of its both sides.About 0.5 millimeter of the screen-aperture of pore screen cloth 2; the screen-aperture of gross porosity screen cloth 1 is pre-2～3 times of sending out the back bead diameter; rest on above the pore screen cloth 2 with the pre-back bead of sending out that guarantees normal pearl footpath; and the bead of adhesion caking is stayed on the gross porosity screen cloth 1; after the bead of adhesion caking enters breaker; join with the qualified bead of pore screen cloth 2 output, a small amount of fine-powdered bead is then stayed on the base plate (not shown) of its below by pore screen cloth 2 becomes discarded object, can not use again.
The vibration principle of pneumatic vibration mechanism 3 is as follows: compressed air enters from compressed air inlet 7, promotes steel ball 9 and rotates in circular track 6, makes the vibration screening device produce vibration.Pneumatic vibration mechanism 3 compares with existing vibrating mechanism, need not complicated motor and transmission mechanism, and structure is simplified greatly, and the life-span is longer.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
