Description

Technical Field

[0001] The utility model relates to the technical field of demagnetizers, in particular to a demagnetizer for circulating and filtering magnetic foreign matter. Background Art

[0002] In the powder processing technology, it is necessary to remove magnetic foreign matter in the material, so an electromagnetic iron remover is generally used to absorb the magnetic foreign matter and then discharge it when the material passes through.

[0003] However, when the electromagnetic iron remover is used in the dry powder process, magnetic foreign matter often wraps around the good material and is discharged together, which greatly reduces the output of qualified finished products.

[0004] Therefore, how to remove magnetic foreign matter in the powder dry process while ensuring that good material will not be discharged along with the magnetic foreign matter has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a demagnetization device for circulating and filtering magnetic foreign matter.

[0006] The utility model provides a magnetic foreign matter circulation filtering demagnetization device, comprising an electromagnetic iron remover, the electromagnetic iron remover is provided with an iron remover inlet for inputting undemagnetized materials;

[0007] The electromagnetic iron remover is provided with an iron remover outlet and is connected with a diverter valve;

[0008] The diverter valve is provided with two outlets, which are respectively set as the material outlet and the slag outlet; the material outlet is used to output the material from which the magnetic foreign matter has been removed, and the slag outlet is connected to the iron remover inlet through a pipe;

[0009] When the electromagnetic iron remover is powered on, the material outlet is opened, the slag outlet is closed, and the magnetic foreign matter is adsorbed on the electromagnetic iron remover;

[0010] When the electromagnetic iron remover loses power, the material outlet is closed, the slag outlet is opened, and the magnetic foreign matter falls into the slag outlet and enters the electromagnetic iron remover from the iron remover inlet.

[0011] The utility model includes two processes, one is that the electromagnetic iron remover is powered on, the material enters the electromagnetic iron remover, and after the magnetic foreign matter is removed by magnetic adsorption, it is discharged from the material outlet; the second is that the electromagnetic iron remover is powered off, the magnetic foreign matter falls from the slag material outlet and enters the iron remover inlet; the above two processes are repeated in a cycle, and the impact force generated when the magnetic foreign matter enters the electromagnetic iron remover again makes the material and the magnetic foreign matter separate, and the material will not be discharged together with the magnetic foreign matter, thereby increasing the output of qualified finished products. In addition, the utility model realizes that the magnetic foreign matter automatically enters the iron remover inlet, reduces the manual burden, and improves efficiency.

[0012] If the pipe is connected to the material conveying pipe, it will be mixed with the material before entering the electromagnetic iron remover. This will not only reduce the separation efficiency of magnetic foreign matter and the material it wraps, but also make the magnetic foreign matter wrap more materials. Based on this, further improvements are: the inlet of the iron remover is connected with a three-way pipe; the three-way pipe is provided with a first inlet, a second inlet and a first outlet; the first inlet is used to input un-demagnetized materials; the second inlet is connected to the pipe; the first outlet is connected to the inlet of the iron remover. In this way, when the magnetic foreign matter and the material pass through the second inlet and the first inlet respectively and enter the first outlet together, a vertical stratification will be formed, and the magnetic foreign matter will fall on one side of the stratification, and the material will fall on the other side; then when it falls into the electromagnetic iron remover, two areas will be presented, and the magnetic foreign matter will fall into one area, and the material will fall into the other area, which not only improves the iron removal efficiency of the material, but also improves the separation efficiency of the magnetic foreign matter and the material it wraps.

[0013] When there is a position error between the three-way pipe and the electromagnetic iron remover, it is difficult to connect. Based on this, a further improvement is that the first outlet and the inlet of the iron remover are connected by a bellows.

[0014] In order to facilitate the magnetic foreign matter to stably enter the second entrance, further improvements are: a suction machine is installed at the second entrance; a pipe is connected to the entrance of the suction machine; and the drop port of the suction machine is connected to the first entrance.

[0015] The diameter of the slag outlet directly affects the stability of magnetic foreign matter entering the second inlet. Based on this, a further improvement is that the slag outlet is connected with a reducing pipe.

[0016] When the electromagnetic iron remover loses power, the slag outlet will open, and the magnetic foreign matter will enter the electromagnetic iron remover under the action of the suction machine. At this time, due to the loss of power in the electromagnetic iron remover, even if the magnetic foreign matter is separated from the material wrapped by it, it will still fall from the slag outlet at the same time, making it difficult to play an effective separation role. Based on this, further improvements are: the outlet of the suction machine is connected to a hopper; a valve is connected between the hopper and the first inlet. In this way, when the electromagnetic iron remover loses power, the valve is closed, and the magnetic foreign matter will accumulate in the hopper; when the electromagnetic iron remover is powered on, the valve is opened, thereby reducing the amount of material entering the slag outlet.

DETAILED DESCRIPTION

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] like Figure 1 As shown, the utility model discloses a magnetic foreign matter circulation filtering demagnetization device, comprising an electromagnetic iron remover 1, the upper end of the electromagnetic iron remover 1 is provided with an iron remover inlet 11 for inputting un-demagnetized materials; the lower end is provided with an iron remover outlet 12, and is connected to a diverter valve 2.

[0022] The diverter valve 2 is provided with two discharge ports, which are respectively set as a material outlet 21 and a slag outlet 22 ; the material outlet 21 is used to output the material from which the magnetic foreign matter has been removed, and the slag outlet 22 is connected to the iron remover inlet 11 through the connecting pipe 3 .

[0023] The on-off states of the material outlet 21 and the slag outlet 22 are opposite. When the electromagnetic iron remover 1 is powered on, the material outlet 21 is opened, the slag outlet 22 is closed, and the magnetic foreign matter is adsorbed on the electromagnetic iron remover 1; when the electromagnetic iron remover 1 is powered off, the material outlet 21 is closed, the slag outlet 22 is opened, and the magnetic foreign matter falls into the slag outlet 22 and enters the electromagnetic iron remover 1 from the iron remover inlet 11.

[0024] The inlet 11 of the iron remover is connected to a three-way pipe 4. The three-way pipe 4 is provided with a first inlet 41 and a second inlet 42 which are obliquely upward, and a first outlet 43 which is vertically downward. The first inlet 41 is used to input materials that have not been demagnetized; the second inlet 42 is connected to the slag outlet 22 through the connecting pipe 3; and the first outlet 43 is connected to the inlet 11 of the iron remover. With such an arrangement, when the magnetic foreign matter and the material respectively pass through the second inlet 42 and the first inlet 41 and enter the first outlet 43 together, a vertical stratification will be formed, and the magnetic foreign matter will fall on one side of the stratification, and the material will fall on the other side; and then when it falls into the electromagnetic iron remover 1, two areas will be presented, and the magnetic foreign matter will fall into one area, and the material will fall into the other area, which not only improves the iron removal efficiency of the material, but also improves the separation efficiency of the magnetic foreign matter and the material wrapped therein.

[0025] The first outlet 43 and the iron remover inlet 11 are connected via the bellows 5. In this way, the position error between the three-way pipe 4 and the electromagnetic iron remover 1 can be ignored, and the connection is convenient. In other embodiments, the bellows 5 can also be replaced by a hose.

[0026] A suction machine 6 is installed at the second inlet 42, and the pipe 3 is connected to the inlet of the suction machine 6. A hopper 7 and a valve 8 are connected in sequence between the drop port of the suction machine 6 and the first inlet 41. When the fan on the suction machine 6 is started, the magnetic foreign matter at the slag outlet 22 is sucked and input into the hopper 7. When the valve 8 is opened, the magnetic foreign matter in the hopper 7 enters the electromagnetic iron remover 1.

[0027] The slag outlet 22 is connected to a reducing pipe 23 , and the connecting pipe 3 is connected to the reducing pipe 23 , thereby reducing the output area of ​​the slag outlet 22 , improving the suction force of the suction machine 6 , and allowing the magnetic foreign matter to stably enter the hopper 7 .

[0028] The utility model includes two processes, one of which is that the electromagnetic iron remover 1 is powered on, the valve 8 is opened, the suction machine 6 is closed, the magnetic foreign matter and the material enter the electromagnetic iron remover 1, and after the magnetic foreign matter is removed by magnetic adsorption, the material is output from the material outlet 21, and the magnetic foreign matter is adsorbed in the electromagnetic iron remover 1; the second is that the electromagnetic iron remover 1 loses power, the valve 8 is closed, the suction machine 6 is opened, the magnetic foreign matter falls from the slag outlet 22, and enters the hopper 7; the above two processes are repeated in a cycle, and the impact force generated when the magnetic foreign matter enters the electromagnetic iron remover 1 again causes the material to separate from the magnetic foreign matter, and the material will not be discharged together with the magnetic foreign matter, thereby increasing the output of qualified finished products. In addition, the utility model realizes that the magnetic foreign matter automatically enters the iron remover inlet 11, reduces the manual burden, and improves efficiency.

[0029] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
