Description

Technical Field

[0001] The utility model relates to a pressurized iron ore concentrate dehydration device, belonging to the technical field of iron ore concentrate dehydration. Background Art

[0002] Iron ore concentrate is a mineral powder made by crushing, grinding, beneficiation and other processing of iron ore. During the production process of iron ore concentrate, it is necessary to first add clean water and stir evenly, and then use a stirred mill to grind it to a qualified grinding particle size, and then pass the mixture through a parallel magnetic field channel. The iron ore concentrate is attracted by the parallel magnetic field and evenly distributed in the magnetic field channel. The non-magnetic gangue is naturally separated from the iron powder and falls off. The water flow washes away the gangue, leaving only the iron ore concentrate, and finally it is dehydrated.

[0003] Most common dehydration treatment devices use filter plates to filter the moisture in iron ore concentrate. Since some iron ore concentrate is small in size, it is easy to be clogged in the filter mesh holes on the filter plate. When the accumulation is thick, it will affect the speed of filtering the moisture, which is inconvenient to use. Utility Model Content

After cleaning, the filter plate 10 will rotate to the inside of the dust cover 20 in the next rotation, and be dried and dust-removed by the heater.

[0029] See also Figure 1 , Figure 2 , Figure 4The lifting assembly includes an active groove 12 located on the side of the support plate 3, a motor 2 is provided on the inner wall of the active groove 12, a gear 3 13 is provided at the output end of the motor 2, a rack plate 14 is meshed on the side of the gear 3 13, a support rod 15 is provided at one end of the rack plate 14 away from the gear 3 13, the bottom of the support rod 15 extending out of the support plate 3 is connected to the pressure plate 11, a slider 16 is provided on both sides of the rack plate 14, and a slide groove 17 matched with the slider 16 is provided on the inner walls of both sides of the active groove 12. By setting the lifting assembly, the dehydration box can be adjusted. 2 is squeezed to filter out the water. The staff puts the iron powder into the dehydration box 2 and starts the lifting assembly to drive the support rod 15 and the pressure plate 11 to descend until the pressure plate 11 penetrates into the dehydration box 2 and contacts the filter plate 10 in the dehydration box 2. The iron powder on the filter plate 10 is squeezed by continuously moving the pressure plate 11 downward. At this time, the water in the iron powder will flow from the filter plate 10 into the dehydration box 2, and the iron powder will be left on the filter plate 10. The lifting assembly drives the pressure plate 11 to squeeze the iron powder, so that the impurities in the iron powder can be quickly squeezed out, thereby effectively improving the dehydration efficiency of the iron powder.

[0030] See also Figure 1 , Figure 2 and Figure 3 A cleaning box 18 is provided on the side of the dehydration box 2, and a water pipe 19 is provided on the top of the cleaning box 18. One end of the water pipe 19 passes through the cleaning box 18 and is connected to a water gun.

[0031] See also Figure 2 and Figure 3 An arc-shaped box 22 is provided on one side of the inner top of the base 1, and a plurality of air outlets are opened on the inner top of the arc-shaped box 22. A heater is provided inside the arc-shaped box 22. Through the arrangement of the arc-shaped box 22 and the heater, the heater can dry and remove dust from the cleaned filter plate 10, thereby ensuring that the filter plate 10 remains dry and is easy to use. The outer sides of the dehydration box 2 and the cleaning box 18 are provided with grooves that match the filter plate 10, and the sides of the filter plate 10 are provided with sealing gaskets 21, which match the grooves.

[0032] When in use, first put the hydrated iron powder into the dehydration box 2, then start the lifting assembly to drive the pressure plate 11 to descend to dehydrate the iron powder, and start the motor 2 by controlling the external switch. The rotation of the motor 2 drives the gear 3 13 to rotate, and the rotation of the gear 3 13 drives the rack plate 14 meshed with it to move. Under the limit of the slider 16 and the slide groove 17, the rack plate 14 moves up and down with the rotation of the gear 3 13, and the movement of the rack plate 14 drives the support rod 15 and the pressure plate 11 to move until The pressure plate 11 penetrates into the dehydration box 2 and contacts the filter plate 10 in the dehydration box 2. The pressure plate 11 contacts the iron ore concentrate on the filter plate 10. As the pressure plate 11 moves downward continuously, the water in the iron ore concentrate flows from the filter plate 10 into the inner bottom of the dehydration box 2, and the iron ore concentrate is retained on the filter plate 10. The pressure plate 11 is driven by the lifting assembly to squeeze the iron ore concentrate, so that the impurities in the iron ore concentrate can be squeezed out quickly, thereby effectively improving the dehydration efficiency of the iron ore concentrate.

[0033] When the filter holes on the filter plate 10 are blocked by the iron concentrate with a smaller volume, the rotating assembly can be started to drive the filter plate 10 to rotate, and then the blocked filter plate 10 in the dehydration box 2 can be replaced to avoid the filter plate 10 being blocked and affecting the drainage. The motor 15 is started by controlling the external switch. The rotation of the motor 15 drives the gear 16 to rotate. The gear 16 rotates one circle and drives the meshing gear 27 to rotate one-sixth of a circle. The rotation of the gear 27 drives the rotating rod 8 to rotate. The gear 27 rotates one-sixth of a circle to drive the next filter plate 1 0 rotates into the dehydration box 2. At this time, a brand new filter plate 10 is installed in the dehydration box 2 to dehydrate the iron ore concentrate (because a sealing gasket 21 is provided on the side of the filter plate 10, and the shape of the sealing gasket 21 is a trapezoidal structure, so when the gear 2 7 drives the filter plate 10 to rotate, the sealing gasket 21 on the side of the filter plate 10 will squeeze the slot on the outer wall of the dehydration box 2, and then fill the gap in the slot, so as to prevent the water in the iron ore concentrate from flowing out of the dehydration box 2 through the gap in the slot when the iron ore concentrate is dehydrated);

[0034] At this time, with the movement of the rotating component, the new filter plate 10 is located in the dehydration box 2, and the previously blocked filter plate 10 will rotate into the cleaning box 18. At this time, the external water pump can be started to input external water through the water pipe 19, and finally sprayed onto the filter plate 10 in the cleaning box 18 through the water gun in the cleaning box 18, so that the iron ore powder blocked in the filter plate 10 can be washed off, thereby facilitating the cleaning of the filter plate 10. After cleaning, the filter plate 10 will rotate to the inside of the dust cover 20 in the next rotation, and be dried and dust-removed by the heater for the next use.

[0035] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
