The material box is made by welding steel plates and mainly used for bearing powdery materials of doped particles. The feed inlet 1 is used for powder material to enter, and in order to adjust the feed speed, a flow regulating device is arranged at the feed inlet 1. For example, the flow rate adjusting means is: the baffle 13 for adjusting the opening of the feed inlet is arranged at the feed inlet 1, and the flow adjusting device can also be a valve with adjustable opening. The workbin can use the steel sheet preparation that thickness is 3mm and below, lightens box whole weight, the preparation, installation of being convenient for. The top of the feed box is provided with an upper cover 10, and the upper cover 10 can be uncovered, so that the feeding condition can be observed conveniently or the screen mesh can be replaced conveniently.

In addition, a hanging table can be arranged in the feed box, and the screen is hung in the feed box. The screen cloth can all be fixed mounting in the workbin in four sides, or only one side articulates in the screen cloth, or directly opposite both sides block respectively in the draw-in groove. The screen cloth separates workbin inside for feeding chamber 4 and material chamber 5, and feeding chamber 4 communicates with feed inlet 1, and the screen cloth of screen cloth is located feeding chamber 4. The screen is the boundary between the feed chamber 4 and the material chamber 5, and material entering the material chamber 5 from the feed chamber 4 must pass through the screen. The material gets into feeding chamber 4 from feed inlet 1, and through the screening of screen cloth, reentrant material chamber 5, the impurity that sieves out etc. falls in feeding chamber 4 bottom to discharge from the slag charge export 3 of feeding chamber 4 bottom. The bottom of the feeding cavity 4 is preferably funnel-shaped, the bottom of the funnel is provided with a slag discharging pipe, a valve is arranged on the slag discharging pipeline, and the slag discharging pipe forms a slag outlet 3. In order to facilitate monitoring whether the material is blocked between the feeding cavity 4 and the slag outlet 3, the material level monitoring device 12 is arranged in the feeding cavity 4, and the existing monitoring device of the material level monitoring device 12, such as a contact type material level signal switch with alarm signal output, outputs the alarm signal in time when the monitoring device monitors that the material is blocked at the slag outlet 3. The bottom of the material cavity 5 is a material outlet 2, the bottom of the material cavity 5 is preferably funnel-shaped, and the material filtered by the screen is discharged from the material outlet 2.

And a hammering device 6 is arranged at the bottom of the screen, and the hammering device 6 is in transmission connection with a power mechanism 7. The hammering device 6 is a device capable of continuously or intermittently knocking the screen mesh, so that the effect of bouncing the screen mesh after being violently knocked is achieved. For example, the hammering device 6 is a rotary hammer including two hammers, each of which is two iron balls having a total weight of 2.5 kg. The hammering device 6 may be mounted on the screen or under the screen of the screen. The power mechanism 7 provides power for the hammering device 6 to knock the screen, for example, the power mechanism 7 is a motor, and the motor is provided with a speed reducing mechanism and a speed regulator, so that low power and high output torque of the motor are realized. Because the motor is only used for knocking the screen, the power is less than or equal to 200W, the power supply voltage is widely selected and can be 380V, 220V, 36V, 24V and the like, and when the voltage is higher than 36V, the motor is provided with a leakage protector. When the motor is provided with the speed reducing mechanism and the speed regulator, the two hammering devices 6 can be driven to knock the screen mesh by the motor at the rotating speed of 3r/min, the screen mesh is knocked for 10 times/min to generate violent bouncing action and then returns to the original position, the rotating speed of the motor is adjustable, and the knocking times are adjustable.

The second screen mesh 9 can be directly placed in a clamping groove of the material box, and the second screen mesh 9 bounces and vibrates when the hammering device 6 knocks. Alternatively, one side, e.g. the lowermost side, of the second screen 9 is hinged to the box and the second screen 9 vibrates in a side-tipping manner when struck by the hammering device 6. The position of the hammering device 6 relative to the screen is suitable for facilitating the blanking, for example, the hammering device 6 is arranged on the higher side of the second screen 9, see fig. 1.

First screen cloth 8 and second screen cloth 9 all incline to set up, and inclination is so that to sieve for suitable, for example the contained angle of first screen cloth 8 and horizontal plane is greater than the contained angle of second screen cloth 9 and horizontal plane. The material is the form that scatters after first screen cloth 8, and the impurity that contains in material and the material can be more even come on second screen cloth 9, and when two-layer screen cloth bounced, can be fine shake off impurity, and do not influence the material and pass through two-layer screen cloth. First screen cloth 8 is arranged in blocking flexible debris such as palpus line and large granule material, and second screen cloth 9 is arranged in filtering other impurity in the material, plays further filterable effect. For example, the first screen 8 has a mesh size of 20.0 × 20.0mm, and the second screen 9 has a mesh size of 1.5 × 1.5mm, 2.0 × 2.0mm, or 2.5 × 2.5 mm. The first screen 8 can filter flexible sundries such as flocculent whiskers and large-particle materials with the diameter more than 20mm, and the second screen can filter particles with the diameter of 1.5mm or less at the minimum, which is determined according to the mesh size of the second screen.
