Detailed Description

The present invention will be described in further detail with reference to the following detailed description.

Examples

A screening device for solid particles or powder is shown in figures 1-3 and comprises a screening component, a material guide component, a material collecting tank 4, a support frame 1 for fixing the screening component, the material guide component and the material collecting tank 4;

the screening assembly comprises a screen frame 2, and a first screen 21 and a second screen 22 arranged on the screen frame 2. The reel 2 is trapezoidal, and the reel 2 downward sloping makes trapezoidal minor face be located the lower part, and trapezoidal long limit is located upper portion. The side wall of the screen frame 2 is detachably connected with the support frame 1 through bolts. The first screen 21 is located at the top of the screen frame 2, the second screen 22 is located at the bottom of the screen frame 2, and the mesh of the first screen 21 is larger than the mesh of the second screen 22. The first screen 21 and the second screen 22 are made of steel wire meshes, and in order to further improve the support strength of the first screen 21 and the second screen 22, cross bars (not shown in the figure) are arranged at the lower parts of the first screen 21 and the second screen 22; two ends of the cross rod are fixed on the screen frame 2 through pins;

the side wall of the screen frame 2 is provided with a lower hopper 24, and the lower hopper 24 is arranged on the side wall of the lowest part of the screen frame 2. Correspondingly, a feed opening is formed at the position corresponding to the position of the screen frame 2 and the feed hopper 24, and the materials intercepted by the second screen 22 enter the feed hopper 24 through the feed opening and are discharged. The bottom of the discharging hopper 24 is provided with a vibrator 25, the vibrator 25 is fixedly connected with the bottom of the discharging hopper 24, and the vibrator 25 is arranged to accelerate the falling of materials, so that the screening and discharging speed is improved.

The material guide assembly is positioned at the top of the screening assembly. The material guiding assembly comprises a material guiding frame 3 and a plurality of baffle plates; the material guiding frame 3 is also trapezoidal, and the inclination direction of the material guiding frame 3 is the same as that of the screen frame 2. Two ends of the baffle are fixed on the guide frame 3, and the baffle is vertical to the sliding direction of the materials to be screened. The baffle is divided into a first baffle 31 and a second baffle 32, and the second baffle 32 is located below the first baffle 31. In this embodiment, two first baffles 31 are provided, and a space for the material to enter the sieving device is formed between the uppermost first baffle 31 and the material guiding frame 3. The first baffle 31 is a straight plate, and a certain gap is left between the bottom of the first baffle 31 and the first screen 21; the second baffle 32 is an arc-shaped plate; the bottom of the second shutter 32 abuts against the second mesh 21.
