[0027] The technical solutions of the utility model will be clearly and completely described below in combination with the embodiments, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] As Figures 1-3 The utility model discloses an embodiment provides a kind of atomized metal soft magnetic powder settlement collection device, including settling tank 1, water inlet pipe 104, multiple filter plates 2 and multiple magnet modules;Settling tank 1 has tank body structure, along the length direction of settling tank 1, water inlet is equipped in one end of settling tank 1, and its other end has drain, one end of water inlet pipe 104 is connected with water inlet, and its other end is connected with atomization barrel 4, for atomization barrel 4 inside atomization water powder mixture 6 is discharged to settling tank 1;Multiple filter plates 2 are arranged and installed in tank body structure along the length direction of settling tank 1, to separate tank body structure into multiple settlement zones, and filter plate 2 is used to delay the flow rate of atomization water powder mixture 6 in tank body structure;Magnet module is installed below each settlement zone, and magnet module is attracted by magnetic force metal soft magnetic powder in atomization water powder mixture 6 in settlement zone.

[0029] Need to be explained, metal steel liquid 5 is atomized into powder after high-pressure water, and water together with water enters inside atomization barrel 4, and metal soft magnetic powder in water slowly deposits into powder collecting tank in the bottom of atomization barrel 4 under the action of gravity.Due to high water temperature, part of metal powder will be suspended in water for a long time and be difficult to deposit, after depositing for a certain period of time, metal soft magnetic powder needs to be dehydrated and dried to control the oxygen content of powder, at this time, the water in atomization barrel 4 needs to be discharged, and the suspended metal powder in water will be discharged into settling tank 1 with water.

[0030] And in the embodiment, atomization water powder mixture 6 in atomization barrel 4 flows into the tank body structure of settling tank 1 along with water inlet pipe 104, under the action of filter plate 2, the flow rate of atomization water powder mixture 6 in tank body structure is slowed down, and the time of atomization water powder mixture 6 staying in each settlement zone is prolonged.At the same time, when atomization water powder mixture 6 flows through each settlement zone, a magnet module is arranged below each settlement zone, and the magnet module is attracted by magnetic force metal soft magnetic powder in atomization water powder mixture 6 in settlement zone, to gather metal soft magnetic powder to the inner bottom wall of settlement zone.After waiting for a period of time, after all atomization water powder mixture 6 is discharged from settling tank 1, then filter plate 2 and magnet module are disassembled, and finally the muddy magnetic powder at the bottom of settling tank 1 is taken out using tool shovel, dried, so that qualified magnetic powder is obtained.

[0031] It can be seen that the atomized metal soft magnetic powder sedimentation collection device utilizes the filter plate 2 to slow down the flow rate of the atomized water powder mixture 6 in the tank structure, and then utilizes the magnet module to adsorb the metal soft magnetic powder in the atomized water powder mixture 6 in the sedimentation area, so as to gather the metal soft magnetic powder on the inner bottom wall of the sedimentation area. 99% of the fine powder can be filtered, the production cycle is shortened, the powder yield is increased, the collection efficiency and the collection amount of the metal soft magnetic powder are greatly improved, and no electricity is needed, thereby reducing the cost.

[0032] Optionally, the material of the sedimentation tank 1 can be polytetrafluoroethylene (plastic), stainless steel, galvanized steel, or one or a combination of several corrosion-resistant materials.

[0033] For the convenience of description, the direction from the water inlet of the sedimentation tank 1 to the water outlet thereof is defined as the front-rear direction. In the embodiment, the sedimentation tank 1 includes a bottom plate and a rectangular frame arranged on the bottom plate, and the rectangular frame and the bottom plate enclose a tank structure, i.e., the top of the sedimentation tank 1 is in an open shape. Figure 3 As shown in the sectional view of the sedimentation tank 1, Figure 3 It can be seen that a hollow interlayer is arranged in the inside of the bottom plate, and the interlayer extends from the left side of the bottom plate to the right side thereof. A plurality of openings corresponding to the interlayers are arranged on the front surface of the bottom plate, and the openings are in communication with the corresponding interlayers. In this way, when the magnet module is placed, the magnet module can be placed into the interlayer from the opening.

[0034] Optionally, in order to facilitate the removal of the magnet module, a drawer structure is slidably arranged in each interlayer. The drawer structure specifically includes a drawer 7 and a handle 701, and the drawer 7 extends into or exits the interlayer from the opening of the interlayer.

[0035] Preferably, the magnet module is a magnet 3, and the material of the magnet 3 can be one or a combination of several magnet materials having magnetic force adsorption to the magnetic powder, such as permanent ferrite, rare earth permanent magnet, or electromagnet. The shape of the magnet 3 is not specifically limited, and can be assembled or integral.

[0036] As a specific embodiment, the magnet module is a rectangular block-shaped magnet 3. In order to maximize the adsorption of the metal soft magnetic powder, the cross section of the rectangular block-shaped magnet 3 is slightly smaller than the cross section of the sedimentation area, so that the magnet 3 can generate an attractive force on most positions of the sedimentation area.

[0037] In the embodiment, the filter plate 2 is detachably installed on the inner wall of the sedimentation tank 1. It should be noted that the filter plate 2 can be installed between the left and right inner walls of the sedimentation tank 1 by means of a clamping groove, a clamp, or a bolt, and the specific installation form is not specifically limited.

[0038] As a specific embodiment, as shown in Figure 2As shown, a plurality of clamping grooves 102 are formed on the left and right inner walls of the settling tank 1, and the clamping grooves 102 on the left and right inner walls of the settling tank 1 are one-to-one corresponding, that is, the left and right ends of the filter plate 2 are clamped into the clamping grooves 102 on the left and right inner walls of the settling tank 1. The filter plate 2 is limited by the clamping grooves 102.

[0039] Further, in order to further improve the stability of the filter plate 2, as shown, Figure 2 a fixing plate 105 is fixedly installed on the right side of each clamping groove 102, that is, a fixing plate 105 is fixedly installed on the right side of the clamping groove 102 on the left inner wall of the settling tank 1 and on the right side of the clamping groove 102 on the right inner wall of the settling tank 1. The filter plate 2 is connected to the fixing plate 105 through bolts when being inserted between the clamping grooves 102 on the left and right inner walls of the settling tank 1.

[0040] It should be noted that, as shown in Figure 1 , Figure 2 and Figure 3 , the height of the filter plate 2 is lower than the depth of the tank structure, so that when the lower surface of the filter plate 2 is in contact with the inner bottom wall of the tank structure, the upper surface of the filter plate 2 is lower than the upper surface of the settling tank 1. To ensure that the atomized water powder mixture 6 can flow smoothly from the space above the filter plate 2.

[0041] In this embodiment, the heights of the plurality of filter plates 2 are the same, that is, when the plurality of filter plates 2 are arranged and installed in the settling tank 1 in sequence, the lower surfaces of the plurality of filter plates 2 are in contact with the inner bottom wall of the settling tank 1, and the upper surfaces of the plurality of filter plates 2 are located in the same horizontal plane.

[0042] As an alternative embodiment, the heights of the plurality of filter plates 2 are in a stepped increasing manner, that is, from the water inlet to the water outlet of the settling tank 1, the heights of the upper surfaces of the filter plates 2 installed in the settling tank 1 gradually decrease. Because the amount of metal soft magnetic powder in the atomized water powder mixture 6 near the water inlet of the settling tank 1 is more, the height of the filter plate 2 near the water inlet of the settling tank 1 is set to be a little higher to intercept more atomized water powder mixture 6. And the amount of metal soft magnetic powder in the atomized water powder mixture 6 far from the water inlet of the settling tank 1 is less, so the size of the filter plate 2 near the water outlet is set to be a little lower to ensure the drainage efficiency.

[0043] Of course, the height of the filter plate 2 can also be flexibly combined, as long as it can play a role in intercepting and delaying the atomized water powder mixture 6.

[0044] In the present embodiment, one end of the water inlet pipe 104 is connected to the water inlet of the settling tank 1, and the other end is connected to the opening on the sidewall near the bottom of the atomizing barrel 4. An opening is formed on the sidewall near the bottom of the atomizing barrel 4, which is close to the bottom of the atomizing barrel 4 so that more atomized water and powder mixture 6 can be discharged, but the opening cannot be too close to the bottom of the atomizing barrel 4 to avoid the metal soft magnetic powder deposited on the bottom of the atomizing barrel 4 from being discharged into the water inlet pipe 104 under the disturbance of the water flow.

[0045] Optionally, the water inlet pipe 104 can be any one of a polytetrafluoroethylene (plastic) pipe, a stainless steel pipe, a galvanized steel pipe, and the like. The water inlet pipe 104 can be a straight pipe or a pipe with a certain angle or curvature. The water inlet pipe 104 can be a round pipe, a square pipe, and other irregularly shaped pipes, which are not specifically limited here.

[0046] In the present embodiment, a drain pipe 103 is connected to the water outlet of the settling tank 1, which functions to discharge the filtered atomized water and powder mixture 6 in the settling tank 1. The drain pipe 103 can be any one of a polytetrafluoroethylene (plastic) pipe, a stainless steel pipe, a galvanized steel pipe, and the like. The drain pipe 103 can be any one of a polytetrafluoroethylene (plastic) pipe, a stainless steel pipe, a galvanized steel pipe, and the like. The drain pipe 103 can be a straight pipe or a pipe with a certain angle or curvature. The drain pipe 103 can be a round pipe, a square pipe, and other irregularly shaped pipes, which are not specifically limited here as long as it can have the function of draining water.

[0047] It should be noted that the water outlet of the settling tank 1 is close to the inner bottom wall of the settling tank 1 to ensure that the atomized water and powder mixture 6 inside can be discharged to the maximum extent.

[0048] In addition, in the present embodiment, a first valve body is installed at one end of the water inlet pipe 104 close to the atomizing barrel 4, and a second valve body is installed at one end of the drain pipe 103 close to the water outlet of the settling tank 1. When the atomized water and powder mixture 6 in the atomizing barrel 4 is in the settling period, the first valve body is in a closed state. It should be noted that if the volume of the atomized water and powder mixture 6 produced in this production is less than the capacity of the settling tank 1, the second valve body can be closed so that the atomized water and powder mixture 6 can be fully settled in the settling tank 1. If the volume of the atomized water and powder mixture 6 produced in this production is much greater than the capacity of the settling tank 1, the second valve body needs to be kept open to avoid the atomized water and powder mixture 6 overflowing from the settling tank 1.

[0049] In the present embodiment, a plurality of supporting legs 101 are welded to the bottom of the settling tank 1 for supporting the settling tank 1. The supporting legs 101 are metal supporting legs, such as stainless steel supporting legs or galvanized steel supporting legs.

[0050] In the embodiment, the water in the atomization barrel 4 is discharged by opening the first valve body on the water inlet pipe 104, and the atomized water-powder mixture 6 in the atomization barrel 4 flows into the tank structure of the settling tank 1 through the water inlet pipe 104, and the flow rate of the atomized water-powder mixture 6 in the tank structure is slowed down under the action of the filter plate 2, thereby prolonging the residence time of the atomized water-powder mixture 6 in each settling area. At the same time, when the atomized water-powder mixture 6 flows through each settling area, a magnet module is arranged below each settling area, and the magnet module adsorbs the metal soft magnetic powder in the atomized water-powder mixture 6 in the settling area by magnetic force, so as to gather the metal soft magnetic powder on the inner bottom wall of the settling area. After the atomized water-powder mixture 6 in the atomization barrel 4 is completely discharged, a period of time is waited, then the filter plate 2 in the settling tank 1 is disassembled, and the drawer 7 is pulled out to take away all the magnets 3. Since the filter plate 2 no longer intercepts the atomized water-powder mixture 6 in the settling tank 1, the atomized water-powder mixture 6 in the settling tank 1 is finally discharged through the drain pipe 103, and finally the mud-shaped magnetic powder at the bottom of the settling tank 1 is taken out by using a tool shovel and dried, so as to obtain qualified magnetic powder.

[0051] When the atomized metal soft magnetic powder settling and collecting device is used to collect the metal soft magnetic powder in the atomized water-powder mixture 6, 99% of fine powder can be filtered and collected, the production cycle is greatly shortened, the powder yield is increased, the collection efficiency and the collection amount of the metal soft magnetic powder are improved, and no electricity is needed, and the cost is low.

[0052] After introducing the atomized metal soft magnetic powder settling and collecting device provided in the embodiment, a water atomization powder production system provided in the embodiment is introduced, which comprises the atomized metal soft magnetic powder settling and collecting device of any one of the above embodiments, the atomization barrel 4 and the powder collecting tank, and the settling tank 1 of the atomized metal soft magnetic powder settling and collecting device and the atomization barrel 4 are connected in communication through the drain pipe 103.
