Embodiment two: the second embodiment is a further improvement on the first embodiment.

Because the present embodiment firstly can not carry out crushing treatment on the agglomerated zinc powder when the agglomerated zinc powder is processed, the agglomerated zinc powder can only be output through the slag discharging plug 3, and zinc powder blocks extracted from the slag discharging plug 3 are required to be crushed again to cause the increase of working procedures, the present embodiment secondly further carries out crushing on the zinc powder blocks on the basis of the conveying mode of the present embodiment I, please refer to fig. 3, 7 and 9, the screening auger 13 carries out spiral conveying, zinc powder is placed on the conveying surface by utilizing the zinc powder, the zinc powder is forced to move upwards, a separation sieve frame 12 is arranged on the conveying surface of the screening auger 13, the separation sieve frames 12 are symmetrically arranged in the conveying surface of the screening auger 13, a plurality of groups of separation sieve frames 12 are arranged, the separation sieve frames 12 are gradually increased in the direction from bottom to top of the screening auger 13, the zinc powder blocks are filtered through the separation sieve frames 12 in the conveying process of the zinc powder through the conveying surface, and the zinc powder blocks larger than the separation sieve frames 12 continue to be conveyed upwards until the zinc powder blocks with the separation sieve frames 12 fall down to the separation sieve frames 12 to the separation sieve frames 12, and the separation sieve frames 12 fall down to the zinc powder from the conveying surface of the sorting sieve frames 12 to the zinc powder to the sorting sieve frames, and the zinc powder is separated from the zinc powder to the zinc powder is separated from the separating sieve frames to the zinc powder.

In the embodiment, in order to further increase the crushing strength of zinc powder, a plurality of crushing ejector rods 14 are arranged on the material conveying surface of the screening auger 13, the crushing ejector rods 14 are equidistantly arranged, the top ends of the crushing ejector rods 14 are tapered, so that in the use process, the agglomerated zinc powder can pass through the tapered tips on the crushing ejector rods 14 at first, and the zinc powder blocks are crushed by friction between the zinc powder blocks and the tips.

Embodiment III: the third embodiment is further improved on the basis of the second embodiment.

Because in the second embodiment, the protruding crushing ejector rod 14 is arranged, when the screening auger 13 is stopped, the unbroken agglomerated raw material is not easy to slide towards the slag discharging plug 3 due to the extension of the crushing ejector rod 14, so that the residual raw material is not easy to clean later, and the third embodiment is used for solving the problem remained when the second embodiment is used at present.

Referring to fig. 4-6 and 11, an adjusting hinge frame 140 is arranged in the sieving auger 13, the bottom end of a crushing ejector rod 14 is fixed on the surface of the adjusting hinge frame 140, the adjusting hinge frame 140 serves as a supporting frame which is the same as that of the sieving auger 13 in a spiral manner, the adjusting hinge frame 140 can move up and down in the crushing ejector rod 14 and drive the crushing ejector rod 14 to eject up and down, a swinging plate 9 is movably arranged at the bottom side of the top of the sieving auger 13, and the end part of the swinging plate 9 is fixedly connected with a raised head 900 positioned below the adjusting hinge frame 140, so that the sieving auger 13 moves up by pushing the raised head 900 through the centrifugal force of the swinging plate 9 in the outward deflection manner in the rotating process of the sieving auger 13, the crushing ejector rod 14 ejects from the conveying surface of the sieving auger 13, and is pushed out by the crushing ejector rod 14 to crush zinc dust in a lump, and in a shutdown state, the swinging plate 9 is subject to gravity sagging until the raised head 900 is separated from the adjusting hinge frame 140, the crushing ejector rod 14 is pulled, and then the zinc dust blocking block between the crushing ejector rods 14 is easily blocked by the sieving ejector rod 14 and separated from the crushing ejector rod 14, and finally the zinc dust is recovered to the rest 100, and finally the zinc dust is recovered to the sieving cavity 100.

Because of the crushing mode, the clustered zinc powder is clamped between the crushing ejector rods 14 and in the space between the sorting sieve frames 12, and the zinc powder blocks can be output only under the stop, so that the crushing efficiency of the zinc powder is reduced.

The third working example is as follows: the conveying motor 5 drives the screening auger 13 to rotate, the swinging plate 9 is deflected outwards by centrifugal force, the raised head 900 pushes the adjusting winch 140 to move upwards, the crushing ejector rod 14 is output from the conveying surface of the screening auger 13, and the upward adjusting winch 140 synchronously pushes the opening and closing pull frame 141 to move upwards, so that the sorting sieve frames 12 at all parts are positioned at preset intervals.

The zinc powder in the screening cavity 100 is conveyed upwards through the conveying surface of the screening auger 13, the agglomerated zinc powder is crushed when the tip of the crushing ejector rod 14 moves, meanwhile, the zinc powder is pushed upwards by the rotation of the screening auger 13, the agglomerated zinc powder passes through the sorting screen frame 12 and falls on the crushing ejector rod 14 from the sorting screen frame 12, secondary crushing is realized, the speed of falling zinc powder blocks from the sorting screen frame 12 is further increased due to the fact that the fan blades 6 continuously blow down air current, the strength of the zinc powder blocks striking the crushing ejector rod 14 is further enhanced, meanwhile, the air current simultaneously blows zinc powder between the crushing ejector rods 14, and the zinc powder is input into the conveying cavity 101 through the screen drum 11 and conveyed to the discharging pipe 4 through the conveying auger 10.

In the rotation process of the screening auger 13, when the windward tank 8 is arranged below the vent hole 700, the air flow in the fan blade 6 directly acts on the swinging plate 9 through the windward tank 8, the swinging plate 9 is blown to deflect downwards, a labor-saving lever is formed because the windward tank 8 is far away from the installation position of the swinging plate 9, in the downward deflection process of the swinging plate 9, the adjusting stranding frame 140 moves downwards, the crushing ejector rods 14 are retracted into the screening auger 13, zinc powder is continuously conveyed upwards by the conveying surface of the screening auger 13, zinc powder clamped between the screening augers 13 is continuously conveyed upwards until zinc powder blocks are conveyed into the screening sieve frame 12 for filtering, the screening sieve frame 12 also moves downwards due to the adjusting stranding frame 140, the separation sieve frame 12 is prevented from continuously blocking, after that, when the windward tank 8 is far away from the vent hole 700, the swinging plate 9 is not directly blown by the air flow, the separation sieve frame 12 is outwards deflected, the separation sieve frame 12 is restored to the preset position, the crushing ejector rods 14 are conveyed again, and zinc powder is conveyed and conveyed again, meanwhile, the zinc powder blocks are conveyed upwards by the crushing ejector rods are deflected outwards, and the separation sieve frame 12 is prevented from being impacted on the drum 11, and the separation sieve 11 is blocked up to the drum 11.

Finally, when the conveying motor 5 is stopped, the swinging plate 9 is deflected downwards by self gravity, the adjusting winch 140 moves downwards and withdraws the crushing ejector rod 14 into the screening auger 13, the separation distance of the sorting sieve frames 12 is maximum, the uncrushed zinc powder blocks drop on the slag discharging plug 3, the zinc powder blocks are extracted through the slag discharging plug 3, and then the zinc powder blocks are taken out.

In order to prevent zinc powder from entering the screening auger 13 and blocking the movement of the adjusting hinge frame 140 when the invention is used, referring to fig. 7, the protruding block sliding with the screening auger 13 is arranged on the crushing ejector rod 14, so that the shielding of the zinc powder is formed, the normal movement of the adjusting hinge frame 140 is prevented from being influenced by the input of the zinc powder, the crushing ejector rod 14 is retracted into the screening auger 13, the tip of the crushing ejector rod 14 is retracted into the screening auger 13, the zinc powder is prevented from being input into the vicinity of the adjusting hinge frame 140 from the crushing ejector rod 14, and the setting of other details of the device can be solved according to common means in the art, and redundant description is omitted.
