[0001] The utility model relates to the technical field of iron-based copper composite powder processing, in particular to a dehydrator for processing iron-based copper composite powder. Background Art

[0002] Iron-clad composite powder (iron-based copper composite powder), developed and produced in recent years, is an ideal material for oil-bearing bearings. It's based on iron powder, with a copper film coated on the surface of the particles, creating a copper-iron-based composite powder with the same appearance and color as copper powder. Compared to oil-bearing bearings made with bronze powder, oil-bearing bearings produced with copper-clad iron composite powder not only meet environmental requirements but are also significantly less expensive. Consequently, they are widely used and adopted by users in the manufacture of powder metallurgy oil-bearing bearings, friction materials, and the binder phase material in diamond tools.

[0003] Among them, CN1209216C discloses an invention patent for a method for manufacturing copper-clad iron composite powder. The method described in the patent is to quickly add reduced iron powder to a copper sulfate solution doped with a stabilizer and having a pH value of 0.5 to 4.8 while stirring, and continue stirring for 2 to 10 minutes to completely coat the surface of the iron powder particles with copper to form a copper-clad iron composite powder; let the copper-clad iron composite powder settle for 3 to 20 minutes, remove the supernatant, and wash with clean water until it is non-acidic; then dehydrate, dry and reduce the powder and then screen it. When the existing dehydrator is used to dry the ultrafine copper-clad iron composite powder, the ultrafine composite powder sticks together, making it difficult to achieve rapid dehydration and drying.

[0043] The locking pipe 75 defines a through hole 701 .

[0044] It should be noted that: during dehydration, the liquid is discharged into the connecting sleeve 71 from the drainage hole 101, and then automatically discharged after being filtered by the filter cartridge 73. The filter cartridge 73 is fixed to the mounting base 72 by using the locking pipe 75 and the pressure rod 74.

Here, the filter cartridge 73 is hollow, and the pressure rod 74 is provided with a pressure plate for pressing the filter cartridge 73, so that the filter cartridge 73 can be pressed onto the mounting base 72 in cooperation with the locking pipe 75.

[0045] The working principle of the dehydrator for processing iron-based copper composite powder provided by the utility model is as follows:

[0046] During use, the electric telescopic rod 3 is controlled to extend by the numerical control box 8, and then the bucket cover 4 is pushed upward through the connecting ring 31, thereby driving the bucket cover 4 away from the fixed bucket 1, and then pouring the copper-based iron powder to be dehydrated into the dehydration bucket 2, and then the electric telescopic rod 3 is controlled to retract, driving the bucket cover 4 to reset and tightly cover the top of the fixed bucket 1. At the same time, the sealing component 5 is used to tightly cover the top of the dehydration bucket 2, and then the motor 13 and the motor 2 62 are synchronously controlled to start, and the motor 13 drives the transmission shaft 12 to rotate. The transmission shaft 12 drives the dehydration bucket 2 to rotate through the hexagonal joint 14, and the copper-based iron powder placed inside is pressed. The material is subjected to high-speed centrifugal dehydration, and the motor 2 62 drives the hollow tube 61 to rotate through the belt, and the hollow tube 61 drives the stirring tube 63 and the stirring rod 64 to stir the copper-based iron powder placed in the dehydration barrel 2, thereby accelerating the dehydration speed and improving the dehydration efficiency. Further, when the hollow tube 61 rotates, the current controller 66 is controlled by the numerical control box 8 to alternately energize the multiple electromagnetic rods 65 at equal intervals, thereby magnetically attracting the copper-based iron powder inside the dehydration barrel 2, so that it is stirred more fully, and then the electric heating rod 67 is powered synchronously, thereby heating and stirring the inside of the dehydration barrel 2, which is conducive to improving the speed of dehydration and drying;

[0047] During dehydration, the liquid is discharged into the connecting sleeve 71 from the drainage hole 101, and then automatically discharged after being filtered by the filter cartridge 73. The filter cartridge 73 is fixed to the mounting base 72 by using the locking pipe 75 and the pressure rod 74. When the filter cartridge 73 needs to be replaced, the connecting sleeve 71 is removed from the bottom end of the fixed barrel 1, and then the locking pipe 75 is unscrewed from the pressure rod 74, the pressure rod 74 is pulled out, and then a new filter cartridge 73 is replaced to facilitate the full recovery of copper-based iron powder.
