Detailed Description
The following detailed description of embodiments of the utility model refers to the accompanying drawings.

The working process of the mud recovery and treatment equipment can be summarized as follows: after the slurry generated by construction is transported to a treatment device by a transport vehicle, the slurry is poured into a slurry inlet hopper 11, the slurry which is agglomerated can be naturally precipitated, and the agglomerated slurry can be scattered by a high-pressure water column output by a flushing device 5 and is in a uniform mixing state; with continued input of the high pressure water column, the water level in the hopper 11 rises, causing the slurry to tumble over the separation barrier 12 between the hopper 11 and the sedimentation tank 2 and into the separation apparatus 3.
Based on the structure of the filter cavity, the inner wall of the filter cavity has a certain gradient. In this way, the fine sand in the slurry is introduced into the slurry tank 4 while leaking out through the filter holes 35, and the slurry in the slurry tank 4 can be put into use again. And the coarse sand retained in the filter cavity can fall into the sedimentation tank 2 along with the slope of the filter cavity under the driving of water flow and the action of gravity. The grit deposited in the sedimentation basin 2 can be tested to determine which engineering sites the grit material is available for, based on the geological formation conditions. Through above-mentioned technical scheme, can effectively separate the mud that the construction produced, obtain coarse sand and fine sand, can carry out reutilization to coarse sand and fine sand according to the construction demand like this. Therefore, the waste of resources is reduced, the resources are optimized and utilized, and the economic efficiency is better. Because the flushing device 5 and the separating device 3 are arranged in a non-contact manner, the separating device 3 can rotate at a constant speed without interference, and therefore coarse sand and fine sand can be effectively separated in a relatively stable state.
Of course, in order to further settle the fine sand particles which are not separated from the slurry, a slurry pump 7 can be arranged, so that the slurry pump 7 can be used for stirring effect, and then the suspension slurry pump 7 is arranged in the slurry settling tank 2, so as to obtain the slurry meeting the construction requirement.
In one embodiment provided by the present disclosure, the separating apparatus 3 comprises a drum 31, a carrier 32 and a screen 33.

In this way, the rotary drum 31 can rotate along with the start of the driving device 6, which not only helps the agglomerated slurry to disperse, but also can effectively separate coarse sand and fine sand in the slurry along with the rotation of the filter screen 33, thereby improving the recovery and treatment efficiency of the slurry.
The flushing means 5 also continuously introduces the high pressure water jets during the treatment process, which causes the high pressure water to flush the slurry, helping to break up the agglomerated slurry and causing fine sand in the slurry to penetrate the screen 33 and then to be introduced into the slurry tank 4 through the discharge openings 34 in the bowl 31. The coarse sand blocked by the filter screen 33 directly falls into the coarse sand pool.
Alternatively, the size of the filter holes 35 is 0.2 mm. In this regard, one skilled in the art can flexibly size the filter openings 35 depending on the use of the coarse and fine sand.
In one embodiment provided by the present disclosure, the separating device 3 further includes a plurality of skeletons 36, two ends of the skeletons 36 are respectively connected to the screen 33 and the drum 31, and the skeletons are uniformly spaced in an area between the screen 33 and the inner wall of the drum 31. The provision of the framework 36 is beneficial to improving the strength of the connection between the screen 33 and the drum 31, so that the screen 33 can effectively bear the load borne during rotation, and thus can effectively rotate along with the rotation of the drum 31.
In one embodiment provided by the present disclosure, the size of the weep holes 34 is greater than the size of the weep holes 35. This can help the fine sand and slurry to be discharged quickly and efficiently.
Alternatively, the discharge holes 34 are configured as square strip-shaped holes, which increases the discharge area, so that the fine sand and the slurry can be discharged in time and efficiently.
In one possible design, the rotating drum 31 includes a flow guiding section, a cylindrical section and a conical section connected in sequence, wherein the flow guiding section is communicated with the slurry inlet hopper 11, and the flow guiding section has a guiding inclined plane, which is beneficial to smoothly guiding slurry in through the inclined plane. The cylinder segment is connected with the driving device 6 in a transmission way, so that the driving device 6 can be conveniently connected, and meanwhile, the driving device 6 is beneficial to driving the cylinder segment to stably and reliably rotate; the conical section is arranged above the sedimentation tank 2, so that the coarse sand smoothly slides along the inclined plane of the conical section, and then effectively falls into the coarse sand tank.
In one embodiment provided by the present disclosure, the brackets 32 are arranged in a plurality of groups and are disposed at intervals in the axial direction of the drum 31. Therefore, the rotary drum 31 can be supported in a multi-section manner, and the condition of stress concentration caused by overlarge load is avoided.
In order to reduce the wear of the drum 31 during rotation, balls may be further provided on the bracket 32, so that the wear of the drum 31 is reduced by the rotation of the balls, and it is also advantageous to rotate the drum 31 smoothly.

It should be noted that the number of teeth of the driving pulley 63 is much smaller than that of the driven pulley 64, so that the reduction and torque increase are further performed by the meshing of the driving pulley and the driven pulley. On one hand, the rotary drum 31 can be reliably rotated, on the other hand, the rotating speed of the rotary drum 31 can be reduced, and the influence of slurry sputtering on the separation efficiency of coarse sand and fine sand is avoided.
Specifically, the motor 61 may be configured as a servomotor 61 model Y132S-4B 3. The size of the motor 61 can be adjusted according to the weight of the separating apparatus 3 when it is fully loaded.
In the present disclosure, the motor 61 is connected to the gearbox 62 through a pulley and belt drive. The mud passes through the filter screen 33 with the high-pressure water washing, then enters the mud pit 4 through mud leaking holes in the outer layer of the equipment, and is discharged into the fine sand sedimentation tank 2. The coarse sand blocked by the filter screen 33 directly falls into the coarse sand pool.
