Wherein, the elastic component includes: the sleeve ring 32 which is sleeved on the rotating shaft in a sliding way, and the compression spring 34, one end of which is connected with the sleeve ring 32, and the other end of which is fixed on the outer side of the material bin 2, can utilize the elastic force of the compression spring 34 when the rotating rod 3 moves, so that the rotating shaft always keeps a preset distance with the rotating rod 3, and the transmission gear 45 and the driving gear 46 are in a mutually meshed state.
It should be noted that the structure of the adjusting assembly in this embodiment is the same as that of the tensioning assembly, except that the tensioning cylinder 38 of the adjusting assembly needs to be disposed obliquely according to the actual situation.
As shown in fig. 4 and 5, in this embodiment, a partition 5 is installed between the inner walls of the bin 2 above the pulverizing device, the partition 5 and the rotating rod 3 are parallel to each other, swing plates 51 are rotatably installed on the inner walls of the bin 2 at both sides of the partition 5, the extending direction of the swing plates 51 is consistent with the length direction of the partition 5, two sides of the top of the partition 5 are hinged with a distributing plate 52, the bottom of the distributing plate 52 is approximately the same as the bottom of the swing plates 51, a first elastic member is installed between the distributing plate 52 and the partition 5, in a static state, the distributing plate 52 forms a predetermined acute angle with the partition 5 under the action of the first elastic member, and in addition, a swing assembly for driving the swing plates 51 to swing reciprocally is further provided on the bin 2.
Specifically, the swing assembly includes: the lifting plate 53 is slidably mounted on the outer side of the material bin 2, which is close to the swinging plate 51, the supporting plate 54 is mounted on the outer side of the material bin 2, the supporting plate 54 is used for supporting the lifting plate 53, a lug 55 matched with the cam 44 is fixed on one side, which is close to the material bin 2, of the bottom of the lifting plate 53, in addition, a second elastic piece is mounted between the swinging plate 51 and the inner wall of the material bin 2, the second elastic piece applies force, which is far away from the distributing plate 52, of the swinging plate 51, a reciprocating sliding block 56 is slidably inserted on the inner wall of the material bin 2, the inner end of the reciprocating sliding block 56 is abutted to one side, which is close to the inner wall of the material bin 2, of the swinging plate 51, an inclined surface is arranged at the outer end of the reciprocating sliding block 56, and the inclined surface is abutted to the top of the lifting plate 53.
When the transmission rod 42 drives the cam 44 to rotate, the cam 44 can abut against the convex blocks 55 to drive the lifting plate 53 to move upwards by a preset height, and when the lifting plate 53 moves upwards, the inner end of the reciprocating sliding block 56 abuts against the swinging plate 51 to swing, so that the advantage of the arrangement is that the distributing plate 52 is driven to swing in the process of throwing phosphogypsum into the material bin 2, and at the moment, the distributing plate 52 can be matched with the swinging plate 51 together to pre-squeeze and crush the agglomerated phosphogypsum, so that the working pressure of the crushing cylinder 31 and the screen 41 is reduced; when the protruding part of the cam 44 rotates in a direction away from the lifting plate 53, the lifting plate 53 moves downwards under the action of self gravity until the bottom of the lifting plate 53 abuts against the supporting plate 54, and the circulation is performed to crush phosphogypsum.
Through the scheme, when the first driving piece is started, power for rotating the crushing cylinder 31 can be provided, and meanwhile, power can be provided for the frame plate 4 and the swinging plate 51.
In addition, since the reciprocating slider 56 is likely to slip from the outer wall of the material bin 2 during the horizontal movement, a limit protrusion for limiting the displacement distance of the reciprocating slider 56 is provided at each of the positions of the reciprocating slider 56 on both the inner and outer sides of the material bin 2.
In addition, in order to further increase the crushing effect of the swinging plate 51 and the distributing plate 52 on the agglomerated phosphogypsum, in the embodiment, symmetrical mounting blocks 57 are fixed at the bottoms of the swinging plate 51 and the distributing plate 52, toothed plates 58 are rotatably mounted between the mounting blocks 57, two sides of the toothed plates 58 penetrate through the mounting blocks 57 through fixed extension rods, limit rings 59 are further connected with the outer ends of the extension rods penetrating through the mounting blocks 57 in a threaded manner, and when the angle of the toothed plates 58 needs to be adjusted, only the limit rings 59 need to be rotated.
It should be noted that, in this embodiment, the first driving member and the second driving member may both use a servo motor, and since the servo motor is relatively common, detailed description is not made, and the first elastic member and the second elastic member may both use relatively common springs.
The embodiment also provides a phosphogypsum solid waste treatment method, which comprises the following steps:
step one: firstly, putting phosphogypsum into a material bin 2, and then starting a first driving piece to drive a crushing device, a vibrating screen device and a swinging plate 51 to move so as to crush and sieve the phosphogypsum;
