All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the invention relates to a device for recovering waste residues generated in production of high-efficiency polyaluminium chloride, which is shown in figure 1 and comprises a supporting shell 1, a feeding pipeline, a filtering device 6, a stepless speed change device, a driving mechanism and a transmission mechanism. The feed pipe extends in the vertical direction and is mounted to the support housing 1, and a diffuser opening is provided in the circumferential wall thereof, so that the slag enters from the feed pipe and diffuses out of the diffuser opening (not shown in the figure). The filtering device comprises a first port 61, a second port 62, a plurality of springboards 63 and a plurality of screen assemblies; the first port 61 is rotatably mounted on the support shell 1 through a support rod 53 and is coaxial with the feed pipe; the second port 62 is located above the first port 61, and is configured to rotate in the same direction as the first port 61 under the action of the continuously variable transmission, and move downwards when the load resistance at one end of the continuously variable transmission is reduced, and the rotating speed is increased until the rotating speed is the same as the first port 61. A plurality of springboards 63 are evenly distributed along the circumferential direction of the feeding pipeline, the upper ends of the springboards 63 are connected to the second port 62, the lower ends of the springboards 63 are connected to the first port 61, and the springboards 63 are configured to be arched inwards when the second port 62 moves downwards, so that the aperture of a central through hole surrounded by the plurality of springboards 63 is reduced.

A plurality of filter screen assemblies are uniformly distributed along the circumferential direction of the feeding pipeline, and each filter screen assembly and the elastic plate 63 are arranged at intervals and comprise an elastic strip 64 and two groups of connecting rods 65; the elastic strip 64 is disposed between two adjacent elastic plates 63, has an upper end mounted to the second port 62 and a lower end mounted to the first port 61, and is configured such that the elastic strip 64 is arched outward when the second port 62 moves downward. Two groups of connecting rods 65 are respectively arranged at two sides of the elastic strips 64, each group of connecting rods 65 comprises a plurality of connecting rods 65 which extend along the horizontal direction and are sequentially arranged along the vertical direction, one end of each connecting rod 65 is arranged on the elastic strip 64, the other end of each connecting rod 65 is slidably inserted into the elastic plate 63, each elastic strip 64 arches outwards when the rotating speed of the second port 62 is increased and moves downwards, the connecting rods 65 connected with the elastic strips are pulled to move outwards to increase the filtering area, and the gap between two adjacent connecting rods 65 of each group of connecting rods 65 is reduced so as to reduce the particle size allowed to pass between the two connecting rods 65; and the included angle between two groups of connecting rods 65 of each filtering component is reduced, so that the extrusion acting force on the waste residue in the filtering device 6 is increased, and the waste residue separation effect is better.

In this embodiment, as shown in fig. 1, the efficient polyaluminium chloride production waste residue recovery device further comprises a driving mechanism and a transmission device, the driving mechanism is a motor 2, the motor 2 is mounted on the support shell 1, and a rotating shaft 22 extending along the vertical direction is arranged on the motor 2; the transmission device comprises two gears and a transmission chain 21, the two gears are respectively fixedly sleeved on the supporting rod 53 and the rotating shaft 22, and the transmission chain 21 is sleeved on the outer sides of the two gears so as to transmit the rotation of the rotating shaft 22 to the supporting rod 53 and further to the first port 61.

In the present embodiment, as shown in fig. 3 to 8, the spring plate 63 is gradually arched inward from both ends toward the middle in the initial state to further arch the spring plate 63 inward when the second port 62 moves downward, so that the hole diameter of the central through hole surrounded by the plurality of spring plates 63 is reduced. The lower end of the spring plate 63 is located at the front side of the upper end along the rotation direction of the first port 61 and the second port 62, so that when the first port 61 and the second port 62 rotate in the same direction, the rotation speed of the first port 61 is greater than that of the second port 62, thereby further twisting the spring plate 63 and increasing the extrusion force to the slag in the filter device 6.

In this embodiment, the distance from the elastic strip 64 to the elastic plates 63 on both sides is the same, and the middle part of the elastic strip 64 is located outside the first port 61 and the second port 62, so that when the elastic plate 63 is twisted, the elastic strip 64 pulls the links 65 on both sides to move outwards, and further the included angle between the two sets of links 65 is reduced.

In this embodiment, the support housing 1 is provided with a discharge port 12, and the discharge port 12 is located outside the filter device 6 to discharge the liquid after the slag separation.

When the device is used, the motor 2 is started, the motor 2 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the supporting rod 54 to rotate through the transmission chain 21 and the gear, so as to drive the first port 61 to rotate. Meanwhile, the rotating shaft 22 rotates to drive the driving cone disc set 3, the driven cone disc set 5 and the steel belt 21 to rotate, and the driven cone pulley 52 of the driven cone disc set 5 rotates to drive the second port 62 to rotate, and the rotating speed is less than that of the first port 62.

Waste residues are put into a feed pipeline and then diffused out from a diffusion opening, the waste residues start to be separated under the action of centrifugal force, the volume and the mass of the waste residues in the filtering device 6 start to be reduced, the rotating resistance between the driven cone pulley 52 of the driven cone pulley set 5 and the steel belt 4 starts to be reduced, the rotating speed of the steel belt 4 at one end of the driven cone pulley set 5 is accelerated, the rotating speed of the second port 62 is accelerated, and the driven cone pulley 52 of the driven cone pulley set 5 drives the second port 62 to move downwards; the filter screen begins the compression, and bullet board 63 takes place to twist reverse and further inwards hunch-up for the aperture of the central through-hole that a plurality of bullet boards 63 enclose reduces, and the increase is to the extrusion effort of the waste residue that is in filter equipment 6, and separation efficiency is higher. Meanwhile, the elastic strips 64 are arched outwards and pull the connecting rods 65 connected with the elastic strips to move outwards, so that the filtering area is increased, and the gap between every two adjacent connecting rods 65 of each group of connecting rods 65 is reduced, so that the particle size allowed to pass between the two connecting rods 65 is reduced; and the included angle between two groups of connecting rods 65 of each filtering component is reduced, so that the extrusion acting force on the waste residue in the filtering device 6 is increased, and the waste residue separation effect is better.

With the smaller and smaller mass and volume of the waste residue in the filtering device 6, the extrusion stroke of the driven cone pulley 52 and the second port 62 of the driven cone pulley set 5 to the waste residue below is also shorter and shorter, the rotating speed of the driven cone pulley set 5 is gradually increased, and finally the waste residue cannot be continuously extruded, so that the common speed of the second port 62 and the first port 61 is finally realized until the separation of the waste residue is completed.

The separated liquid is discharged from the discharge port 12 for subsequent operations.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
