Embodiment 1
[0031] The embodiment of the present invention provides a sludge dewatering process loaded with magnetic powder, including the following content:
[0032] Step 1: Collect the sludge from the sedimentation tank, add water and stir into a slurry, the mass ratio of water and sludge is 0.5-5:1, the purpose of which is more convenient to separate the magnetic powder in the sedimentation;
[0033] Step 2: Use the magnet sleeved with the isolation sleeve to extend into the mud to absorb the magnetic powder, and the magnetic powder in the mud is adsorbed by the magnet. The isolation sleeve is used to prevent the magnetic powder from being directly adsorbed on the magnet, which is difficult to separate. The magnet can be separated by an electromagnet or a permanent magnet. Isolate the sleeve and the magnet, collect the magnetic powder, remove the magnet after the adsorption is completed, and then separate the isolation sleeve. The magnetic powder attached to the upper end of the isolati...
Embodiment 2
[0038] refer to figure 1 and figure 2 , the dewatering device used in the sludge dewatering process of magnetic powder, including:
[0039] The two uprights 4, the crossbar 5, the filter cylinder 7 and the crossbeam 8, the two ends of the crossbeam 8 are fixedly connected to the uprights 4 respectively, the cross-section of the uprights 4 is circular, and the two ends of the crossbars 5 are slidably fitted on the uprights 4, that is, the horizontal The rod 5 can be lifted and lowered on the upright column 4. The lower end of the filter cylinder 7 is fixed in the middle of the cross bar 5 and is in a conducting state. A mud pipe 10 is fixedly connected in the middle, and the mud pipe 10 is communicated with the filter cylinder 7. Through the mud pipe 10, the mud after adsorbing the magnetic powder is sent to the filter cylinder 7. The middle part of the cross bar 5 is fixedly connected with a valve body 11. At the lower end of the closed filter cartridge 7, when necessary, t...
